High-speed chuck for aluminum alloy wheel

Abstract

The invention discloses a high-speed chuck for an aluminum alloy wheel, belonging to the machining process equipment for the aluminum alloy wheel. The high-speed chuck is capable of realizing quick mounting (loosening) of the aluminum alloy wheel, and the mounting time taken is one quarter of that of the existing chuck; and the high-speed chuck is capable of mounting the aluminum alloy wheels of a series of diameters, and does not need to be frequently replaced and adjusted. Three driving cylinders 1, three pairs of synchronous gears 10, six jaw shafts 9, six jaws 12 and a synchronous turntable 4 are mounted on the chuck body 14; and a locking sleeve 11 is connected to the synchronous gears 10 and the jaw shafts 9. The driving cylinders 1 fixed to the chuck body 14 acts to drive the synchronous turntable 4 to rotate; the swinging of three synchronous gear oscillating arms 3 and the rotation engagement of three gear pairs 10 are realized through three lead pins 6 which are arranged on the synchronous turntable 4 and embedded in the lead grooves of the synchronous gear oscillating arms 3, so that the jaws 12 at the upper ends of the jaw shafts 9 are closed up; therefore, quick fastening of the aluminum alloy wheel is completed. The high-speed chunk is quick in mounting, accurate in centering, reliable in locking, and universal.

Description

technical field [0001] The invention relates to a clamping device used for machining aluminum alloy wheels of cars. Background technique [0002] The machining of the aluminum alloy wheel of a car is usually carried out by using a chuck similar to that used in a lathe and a special mechanical buckle device. The disadvantages of this type of chucking method are: 1. It generally takes about 8 seconds to install an aluminum alloy wheel, and the production cycle is relatively slow; 2. Chips often enter the gap between the chucks and need to be cleaned continuously, otherwise it is easy to cause jamming Phenomenon; 3. The chuck claws have a stepped structure with different heights of the wheel abutment surface, so the wheels are prone to tilt when loading the chuck; 4. The chuck is driven by an oil motor and a hydraulic station is required. Contents of the invention [0003] In view of the shortcomings of the foregoing chucks, the purpose of the present invention is to realize...
