技术领域Technical Field

背景技术Background Art
夹持卡盘主要用于工件的定位夹持，应用于各类工件加工设备中。其中一类夹持卡盘，在进行工件的夹持后，通常需要控制卡盘转动，进而方便带动工件转动，进而对工件不同的部位进行加工。目前，市面上有一类夹持卡盘，是通过气压带动活塞移动，进而带动夹持爪动作进而实现工件的定位夹持以及松开，而卡盘是通过外套筒与转动座连接进而实现卡盘的转动的，这种结构的缺陷是：活塞结构一般是设置在外套筒内的，这就导致外套筒的体积变得很大，而且在外套筒内设置活塞结构，需要设置中间轴对其进行支撑，结构相对复杂，同时这种结构的受力部位主要其中在外套筒内，导致设备整体的受力情况并不均衡，导致设备运行的稳定性较差。The clamping chuck is mainly used for positioning and clamping workpieces, and is applied to various types of workpiece processing equipment. One type of clamping chuck usually needs to control the rotation of the chuck after clamping the workpiece, so as to facilitate the rotation of the workpiece and process different parts of the workpiece. At present, there is a type of clamping chuck on the market, which drives the piston to move by air pressure, and then drives the clamping claw to move to achieve the positioning, clamping and loosening of the workpiece, and the chuck is connected to the rotating seat through the outer sleeve to achieve the rotation of the chuck. The defect of this structure is that the piston structure is generally arranged in the outer sleeve, which causes the volume of the outer sleeve to become very large, and the piston structure is arranged in the outer sleeve, and an intermediate shaft needs to be arranged to support it, and the structure is relatively complex. At the same time, the stress-bearing part of this structure is mainly in the outer sleeve, resulting in the overall stress of the equipment being unbalanced, resulting in poor stability in the operation of the equipment.
