A linear guide rail structure includes a guide rail, a dustproof cover, a pressure-exerting plate, and a locking member. The guide rail extends along an axial direction. The guide rail has at least one locking hole extending from a top surface in a height direction perpendicular to the axial direction. The dustproof cover is disposed on the top surface of the guide rail to cover the locking hole. The pressure-exerting plate is disposed on an end portion of the guide rail to press against the dustproof cover. The locking member includes a fastener and at least one pressure-exerting block. The fastener is fixed to the end portion of the guide rail. The pressure-exerting block is locked into the fastener in the height direction to abut against the pressure-exerting plate in the height direction, so that the pressure-exerting plate is pressed against the dustproof cover.

The present application discloses a self-locking linear guide rail channel detection device, comprising: a detection platform for placing the guide rail to be detected; a detection device arranged on the detection platform; a conveying device connected with the detection device and is configured to push the detection device to slide horizontally along the detection platform; a locking device configured to fix the guide rail to be detected. In the present application, the guide rail to be detected is fixed on the placing platform by the vertical clamping mechanism and the side positioning and clamping mechanism, and a U-shaped groove linear motor drives the detection device to detect the channel of the linear guide rail, which greatly improves the detection accuracy and saves money. It reduces the labor cost; it is of great significance to promote the development of the bearing guide industry.

An actuator is equipped with a body and a slider. Body side rail grooves are formed in side wall portions that constitute the body. On the other hand, slider side rail grooves are formed in the slider. Body side guide rails and slider side guide rails are provided in the body side rail grooves and the slider side rail grooves, respectively. Circular arc grooves serving as ball grooves are formed by body side ball receiving portions of the body side guide rails, and slider side ball receiving portions of the slider side guide rails.

For the purpose of improving a protective effect of a home appliance device, in particular a home appliance chiller device, is proposed comprising: a telescopic guiding unit, which is convertible at least from a fully contracted state to a fully extracted state and vice versa, and has at least one stationary guiding element; and comprising a cover unit, which at least mostly covers the stationary guiding element at least in the fully extracted state.

To provide an actuator with which side face covers can be easily attached and detached without damaging a top face cover, and workability is enhanced, and cost can be reduced without upsizing the actuator, by fastening and fixing the actuator to a base stand from above the actuator in a state in which the side face covers are removed. In an actuator having a long screw shaft with a first roller rolling groove in a spiral shape formed on an outer periphery, an inner block where a screw hole through which the screw shaft penetrates is formed, and which has a second roller rolling groove that is formed on an outer periphery to be parallel with the screw shaft, an outer rail that faces the second roller rolling groove, and a plurality of rollers that are respectively arranged between the screw shaft and the inner block, and between the inner block and the outer rail, side face covers that are laid between a pair of end portion members that are installed at both end portions of the screw shaft, and a top face cover that is disposed to close an opening portion that is formed between the side face covers and is opened parallel with the screw shaft are included, the side face covers each includes a top plate that is formed to be parallel with the top face cover, and a side plate that hangs from one end of the top plate, and the end portion members each has posture retaining device that contacts a corner portion of the top plate and the side plate.

A cap of a linear guide device includes a receiving part configured to receive hitting of a hitting jig, a fitting part extending from the receiving part, having an outer diameter to be an interference with the counterbore part, and being press-fitted into the counterbore part, a foreign material receiving groove arranged at an outer circumference of the fitting part, and configured to receive a foreign material generated from the fitting part when the cap is hit into the counterbore part, and a gas discharge groove extending to reach an inside of the counterbore part from the foreign material receiving groove, with the fitting part being press-fitted into the counterbore part at the outer circumference of the fitting part, and configured to discharge a gas in the inside of the counterbore part to a foreign material receiving groove side.

The present invention relates to a guide device for a machine tool comprising a base body having at least one contact surface, a guide rail having at least one bearing surface and a guide axis, and a plurality of exchangeable support plates for positioning the guide rail on the base body.

An actuator is equipped with a body and a slider. Body side rail grooves are formed in side wall portions that constitute the body. On the other hand, slider side rail grooves are formed in the slider. Body side guide rails and slider side guide rails are provided in the body side rail grooves and the slider side rail grooves, respectively. Circular arc grooves serving as ball grooves are formed by body side ball receiving portions of the body side guide rails, and slider side ball receiving portions of the slider side guide rails.

A linear guide rail structure includes a guide rail, a dustproof cover, a pressure-exerting plate, and a locking member. The guide rail extends along an axial direction. The guide rail has at least one locking hole extending from a top surface in a height direction perpendicular to the axial direction. The dustproof cover is disposed on the top surface of the guide rail to cover the locking hole. The pressure-exerting plate is disposed on an end portion of the guide rail to press against the dustproof cover. The locking member includes a fastener and at least one pressure-exerting block. The fastener is fixed to the end portion of the guide rail. The pressure-exerting block is locked into the fastener in the height direction to abut against the pressure-exerting plate in the height direction, so that the pressure-exerting plate is pressed against the dustproof cover.

A low dust linear module includes a rail unit, a slide seat unit, a dustproof strip and two magnetic members. The two magnetic members are disposed at the two slide seat end portions of the slide seat, the first magnetic attraction gap is defined between the magnetic attraction area and a corresponding one of the magnetic members, and the second magnetic attraction gap is defined between the magnetic attraction area and the slide seat cover. When the dustproof strip passes through and are magnetically attracted by the magnetic members, a gap will appear between the magnetic members and the slide seat and the slide seat cover, so that the magnetic members and the dustproof strip are kept in a gap without friction, so as to avoid the generation of dust due to friction, so that the linear module can operate normally and maintain the standard of the working environment.
