The invention relates to a method, a tool receptacle (13), and an apparatus for turning a face of a workpiece (2, 102) with a tool (3), wherein the workpiece (2, 102) is held in a workpiece receptacle (12) rotating about an axis of rotation (100) of a workpiece spindle, wherein, for producing and/or machining a workpiece contour having convex and/or concave portions on the face (20) that extend over defined angles of rotation, the tool (3) and the workpiece (2, 102) are moved back and forth relative to one another in an axial movement along the axis of rotation (100) of the workpiece spindle, said axis being synchronized with the rotational movement of the workpiece (2, 102), and wherein a blade (30) of the tool (3) is aligned at least in the cutting direction and/or transverse to the cutting direction opposite to the surface normals (N) of the workpiece contour to be produced and/or machined, in such a way that an effective clearance angle (α) and an effective cutting angle (γ) remain at least virtually constant opposite to the surface normals (N). The invention relates to a workpiece (2, 102) having a turned face.

The invention discloses an improved wheel alignment device which comprises a rack, a cylinder, a servo motor, a hollow shaft and the like. When the improved wheel alignment device is used, a stopper on a roller table centers a wheel, air enters at the lower end of a large piston and causes a long cylinder rod, a flange end cover, an expanding sleeve and the like to rise; the flange end cover is in contact with a wheel flange plate, and after the expanding sleeve is in contact with a central hole, air enters at the upper end of a small piston of a small cylinder, a short cylinder rod pulls an expanding core downwards, and the expanding sleeve clamps the central hole of the wheel; the servo motor causes the hollow shaft and the wheel to rotate by a belt pulley I and a belt pulley II, and the hollow shaft and the wheel stop rotating after a sensor finds the position of a valve hole of the wheel; at the moment, lifting cylinders cause a supporting plate to rise to a certain height through guide pillars, and a large cylinder causes the wheel to descend and the lower end surface of the wheel to fall above the supporting plate. The improved wheel alignment device can realize the alignment function before the automatic machining of wheel finish turning in use, and when the wheels with different wheel widths and different offset distances are automatically produced, programs do not need to be switched.

A wheel hub special drilling device comprises a main shaft transmission device, which has a transmission mechanism base and a transmission mechanism mounted on the transmission mechanism base, wherein the transmission mechanism comprises an X-axis transmission mechanism, a Y-axis transmission mechanism and a Z-axis transmission mechanism which are used for respectively moving a main shaft in three vertical axial directions; a main shaft, which is mounted on the vertical Z-axis transmission mechanism; a drilling tool, which is mounted on the main shaft and is rotationally driven by the main shaft; a clamp device, which is used for clamping and fixing a wheel hub to be processed.

Disclosed is a device for automatically removing burrs from a riser of an aluminum alloy wheel. The device is composed of a frame, a clamping gear rack structure, a support plate, a servo motor and the like. When a clamping cylinder drives a first sliding plate to move, clamping wheels are controlled to center and clamp the wheel, and the servo motor controls the rotation of the clamping wheels, so that the wheel may rotate while being clamped. When a distance adjusting cylinder drives a second sliding block to move, a first sliding block and the second sliding block move synchronously under the action of a feed gear rack structure, so that a first deburring tool and a second deburring tool move synchronously to adjust the distance between them according to the diameter of a cap slot.

A rim drilling and milling machine has a bottom base, a table, and a clamping unit. The clamping unit is fixed on the table and has a clamping base and multiple clamping members. Each clamping member has at least one jaw each having a jaw body, a clamping groove recessed in the jaw body, and an abutting protrusion formed between a top surface of the jaw body and the clamping groove. A distance defined from a bottom surface of the clamping groove of each of the at least one jaw to a bottom surface of the bottom base ranges from 850 millimeters to 1000 millimeters. The rim drilling and milling machine can firmly and stably clamp a wheel rim, and the wheel rim can be clamped at a position for a user to easily see a processing area of the wheel rim.

A wheel fixture is disclosed. A main shaft drives a first positioning pull rod on a chuck body to extend and contract in the radial direction via a tightening screw, a clamping jaw is at a position within the travel range of extension and contraction, a wheel is positioned and clamped by the fixture, airtight support blocks are pressed down by the wheel and flush with the support plane of the clamping jaw, at this time, airtight ejector rods press second O rings to prevent air from flowing out of the airtight detection position, a detection system of a machine tool detects a preset air pressure value which indicate that the wheel has been placed correctly, and if the wheel is not placed correctly on the fixture, the machine tool will alarm through the detected pressure feedback.

A lathe fixture for machining a hub is characterized in that a power chuck (10) is installed inside a base (5), a positioning connecting block (6) is installed on the power chuck (10), a fan-shaped claw (7) is installed on the positioning connecting block (6), a pressing block (18) is installed on the base (5), and a first support plate (16) is arranged; the shell (2) is arranged in a back cavity of the base (5) from bottom to top, the force transmission shaft (4) penetrates through the base (5), the force transmission rod (3) is fixedly arranged in a groove of the shell (2), the first support plate (16) and the second support plate (14) are respectively arranged at the front end and the rear end of the shell (2), the balance block (15) is fixed between the first support plate (16) and the second support plate (14) through two guide posts (17), the spring (13) is arranged in the groove of the balance block (15) and the second support plate (14), and the cover plate (1) is fixedly arranged at the lower end of the shell (2); the invention provides a clamp with a centrifugal force compensation mechanism.
