The antenna used to transmit a signal upon activation of a microswitch.

An object of the present invention is to provide a clamping device in which replacement work is easy and hydraulic hoses do not need to be laid between a body of the clamping device body and a pressurization device. The present invention is a clamping device in which a pressurization device (4) is configured from a plunger cylinder unit (5) that accommodates a pressure medium (M) provided in a body part (1), a plunger unit (6) that moves through the interior of the plunger cylinder unit (5) and pressurizes the pressure medium (M), and a manual operation part (7) for operating the movement of the plunger unit (6). A clamp part (3) is detachably and replaceably provided to the body part (1).

The present application provides a material transferring and positioning device for a wheel machining center, which includes a base plate, a base, a first bearing, a first shaft sleeve, a hydraulic cylinder brake, a rotary cylinder, a cap and so on. The application may meet the positioning requirement of the wheel machining center, and has the advantages of simple structure, convenient manufacture, stable performance, high positioning precision and simple operation, so that it is very suitable for automatic mass production.

A conveyance apparatus includes two clamp mechanisms. Each of the clamp mechanisms is configured to freely change its state among a fully clamping state, a semi-clamping state, and a non-clamping state. When an object is delivered from a first clamp mechanism that is holding the object to a second clamp mechanism, the second clamp mechanism is brought into the semi-clamping state to temporarily hold the object. Then, the first clamp mechanism is brought into the non-clamping state and the second clamp mechanism is brought into the fully clamping state.

In a rod hole (19) of a holding rod (18) held in a guide hole (17) of a piston (10), a limit switch (20) is fixed and a detection rod (21) is inserted. A first engagement ball (30) and a second engagement ball (40) are configured to be in contact with a first cam surface (32) and a second cam surface (42), respectively, which are provided at an outer periphery of the detection rod (21). The first engagement ball (30) and the second engagement ball (40) are configured to be in contact with a first pushing portion (35) and a second pushing portion (45), respectively, which are provided inside the guide hole (17). The position of the piston (10) is detected by electrically or electronically detecting the movement of the detection rod (21) by the limit switch (20).

A device for stabilizing a workpiece, in particular a thin-walled workpiece mounted in a machine tool, comprises at least one base; and a plurality of stabilizing elements. The stabilizing elements protrude away from one surface of the base, wherein the stabilizing element comprises a cylinder and a rod arranged therein and the rod can be driven hydraulically to move in the axial direction of the stabilizing element such that the rod of at least two of the stabilizing elements can be brought into contact with one surface of the workpiece.

A steering knuckle casting hydraulic fixture includes a positioning mandrel, a pair of flat keys fixed on a bottom surface of a fixture body, a linear bearing and an elastic taper pin match a steering knuckle casting, an angle positioning seat, a straight pin, an angle positioning nail, an angle clamping nail, a nut, a spring, a spring seat and a linear cylinder are used to restrict the rotational freedom of the casting around the Z axis, hydraulic corner cylinders, pressure plates, and support nails are used to clamp the casting, and three guide blocks are used to guide the installation of the steering knuckle casting.

Disclosed is a wheel milling window device, composed of a bottom plate, guide blocks, clamping slide blocks, mounting keys, hydraulic cylinders, hydraulic pipelines, connecting blocks, pressure claws, first rotating shafts, second rotating shafts, end face blocks, a mandrel, a mandrel seat, a locking jackscrew, a mandrel height adjusting post, a mandrel guide post, a mandrel guide post locking screw, a locking ring, circumferential positioning posts and circumferential slide blocks. The device can reduce the manufacturing cost, shorten the manufacturing period, effectively reduce the time for replacing a fixture and improve the efficiency of milling a wheel window.

The invention relates to a transport device comprising a rotary object carrier which comprises object carrier elements arranged so as to be distributed around the circumference, on which carrier elements objects are arranged which are transported on a circular movement path from work station to work station of a production facility. Furthermore, the invention relates to a production facility for making products, in particular containers filled with a medical product, comprising a transport device of this kind, as well as to a method for transporting objects from work station to work station of a production facility. The transport device according to the invention is characterised in that one or more actuator units 18.1, 18.2; 12.1, 12.2 are assigned to one object carrier element 6 or to a plurality of object carrier elements 6, which units can move together with the object carrier element 6 or the object carrier elements 6. Since the actuator units 18.1, 18.2; 12.1, 12.2 rotate together with the object carrier elements, process steps can be performed on the objects that are assigned to the object carrier elements directly on the object carrier elements. A stationary arrangement of actuators that engage with the objects from the outside is therefore not required. This makes the entire production process more flexible. The actuator units are preferably provided with media by a central supply device by means of a rotary feedthrough.

The present application provides a stationary fixture for machining of an aluminum alloy wheel, includes a machine tool base, first supports, end covers, a first power shaft, bearings, a second end cover, and the like, wherein the first support and a second support are mounted on the machine tool base, the first power shaft is mounted inside a bearing seat, a group of bearings is mounted between the bearing seat and the first power shaft, a nut is mounted at the left end of each bearing to position the inner ring of the bearing, the first end cover is mounted on the left side of the bearing seat at the upper end of the first support by screws, the first sealing ring is mounted between the first end cover and the first power shaft, and the second end cover is fixed to the right side of the bearing seat.
