A wheel rim chuck has a chuck seat (10) and multiple soft jaws (20). The soft jaws are arranged radially at equiangular intervals and slidably mounted on the chuck seat (10). Each soft jaw (20) has a claw (21) having a protrusion (211), a clamping groove (213), and an inclined plane (216). The protrusion (211) protrudes from a side of the soft jaw (20) away from the chuck seat (10). The clamping groove (213) is recessed in a side of the protrusion (211) facing the center (111) of the chuck seat (10) and having a side wall (214) and a bottom wall (215). The inclined plane (216) extends longitudinally and obliquely from the bottom wall (215) away from the side wall (214) of the clamping groove (213).

A manufacturing method for a vehicle wheel includes an overlap cutting step in which lathe machining is performed on a design portion of the vehicle wheel at feed speed that allows cutting marks to be connected with each other in a radial direction with a first cutting depth from a given reference position, and a non-overlap cutting step in which, after the overlap cutting step, lathe machining is performed on the design portion at feed speed that allows cutting marks to be separated from each other in the radial direction with a second cutting depth from the reference position, the second cutting depth being deeper than the first cutting depth.

A tool-transition-free machining method includes: first, a primary turning is conducted, then holes are drilled out by a machining center, and finally a secondary turning is conducted.

A machined wheel post-processing equipment includes a wheel inlet roller way, a lower machine frame, lower guide posts, lower air cylinders, a supporting plate, guide sleeves, a lifting table, guide rails, a clamping cylinder, a left sliding plate, a right sliding plate, a rack and pinion, servomotors, a lifting roller way, clamping wheels, a first servomotor, and a overturning platform.

A device for removing tool joint edge burrs on a cap slot edge and an outer rim of a vehicle wheel includes a vehicle wheel positioning system and a cutter system. The vehicle wheel positioning system is used to make a rotating center of a cap seam allowance superposed with that of the cutter system. The cutter system includes a pyramid cutter and four blades, the pyramid cutter is used to remove burrs on the cap slot edge of the vehicle wheel, and the four blades are used to remove burrs on the outer rim of the vehicle wheel.

The disclosure provides a device for milling wheel window burrs on line, which is composed of a frame, a base plate, a lifting cylinder, a first bracket, a bearing base, a linear bearing, a mounting plate, a guide shaft, a lifting shaft, a first servo motor, a first synchronous pulley, a connecting plate and the like. The device comprises a lifting portion, in which the base plate is fixed on the frame, the mounting plate is fixed on the base plate via the first bracket, the bearing base and the lifting cylinder are fixed on the mounting plate, and the lifting shaft is mounted on the bearing base via the linear bearing.

A rim drilling and milling machine has a base (10), a column (20), a turret (30), a saddle (40), a table (50), and a fixture unit (60). The fixture unit (60) has a foundation (61) and four clamping seats defined as two first clamping seats (63A) and two second clamping seats (63B). The first clamping seats (63A) are slidably mounted on the foundation (61) along a first radial direction, and are disposed at positions diametrically opposite in the first radial direction. The second clamping seats (63B) are slidably mounted on the foundation (61) along a second radial direction perpendicular to the first radial direction, and are disposed at positions diametrically opposite in the second radial direction. The four clamping seats can clamp at four equiangular points of a wheel rim.

The present application provides a device for correcting an aluminum alloy wheel, which is mainly composed of a frame, an expansion cylinder, a correction motor, a feed motor and the like. A hub positioning unit initially positions a hub to prepare for positioning a center hole expansion sleeve; a hub feed unit performs precise center hole positioning on the hub and completes upward feed movement of the hub; and a tool correction unit completes hub correction through a rotating standard correction cutter head. The device may meet the process requirements of wheels in flow production, improve the runout and balance qualified rate of products, and solve the problems of decentraction of the outer diameter in the first procedure and the second procedure and deformation of rim bulges.
