Problems solved by technology
[0002] In the existing industrial production, the clamping device for clamping the workpiece with a spring chuck is widely used. The spring chuck is generally internally expanded. This clamping device is widely used on automatic lathes for fast clamping of the workpiece. , improve production efficiency, and in the process of clamping workpieces, such as iron filings on the outer surface of spring chucks, supports, etc., or burrs on the workpiece, the clamping and positioning of the workpiece will be inaccurate, which will cause batches of workpieces to be scrapped. Damage to parts such as chucks, etc., increases costs

The invention relates to the field of machining equipment, in particular to a clamping device for clamping workpieces. In a clamping process, if parts or workpieces have iron scraps, burrs or the like, the clamping and locating of the workpieces are not accurate and the parts or workpieces are declared worthless in batches. The invention discloses a clamping device. The clamping device comprises a spring clamping head and the like, a chuck holder and a support fixedly connected with a clamping head holder. The spring clamping head passes through the inner cavity threads of the support and is connected with the clamping head holder. A nut is fixedly connected with the inner cavity of the clamping head holder. Tightening screws are sleeved in the inner cavity of the nut. Tightening screw rods are connected with the tightening screws by threads. The other end of the chuck holder is provided with an air inlet sleeve. A mandril passes through the air inlet sleeve and the inner cavity threads of the chuck holder to be connected with the nut. The chuck holder and the clamping head holder are both provided with communicated long slots to allow compressed air to pass through. By adoption of the clamping device disclosed by the invention, the clamping accuracy of workpieces is improved. When the clamping is not accurate, the clamping device is capable of detecting the clamping condition automatically and alarming, so that the production cost of workpieces is reduced.
Description
Technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a clamping device for clamping a workpiece. Background technique [0002] In the existing industrial production, the clamping device that clamps the workpiece with the collet chuck is widely used, and the collet chuck is generally inwardly expanded. This kind of clamping device is widely used on the automatic lathe to quickly clamp the workpiece. , Improve production efficiency, and in the process of clamping the workpiece, such as the spring chuck, support, etc., when there are iron filings on the outer surface or the workpiece has burrs, etc., the clamping and positioning of the workpiece will be inaccurate, which will cause the workpiece to be scrapped in batches. Damage to parts such as chucks, etc., increase costs. Summary of the invention [0003] The purpose of the present invention is to solve the above-mentioned existing shortcomings and provide a clamping devic...
