Problems solved by technology

[0003] The tailstock locking mechanism of the existing rotary net making machine uses two splints and a wrench to directly lock the tailstock on the slide rail. In order to protect the slide rail, nylon blocks are usually lined between the splint and the slide rail. The structure makes the locking effect very poor, and the tailstock will slip under the action of the axial force generated by the compressed air, and there is a defect that it cannot be locked firmly

Abstract

The invention relates to a tailstock locking device, comprising an end cap and a stand, wherein the stand is provided with a big carriage which moves and is positioned along the stand; the big carriage is provided with a small carriage which moves in parallel to the moving direction of the big carriage; the small carriage is provided with a support 1 which is horizontally provided with a rotation shaft in the direction consistent to the moving direction of the big carriage and the small carriage, and the end cap is arranged on one end of the rotation shaft; and a control device for controlling the movement amount of the small carriage is arranged between the big carriage and the small carriage. The tailstock locking device is suitable for circular screens with different lengths and ensures that slippage cannot generate under the action of the axial force of compressed air, therefore, the compressed air in the circular screen cannot be leaked.

Description

technical field [0001] The invention relates to a rotary screen machine used in the printing industry, in particular to a tailstock locking device of the rotary screen machine. Background technique [0002] The rotary screen making machine is a kind of equipment used to make printing templates. The rotary screen is a circular thin-walled long cylindrical object made of metal. When processing images on the rotary screen, in order to maintain its rigidity and roundness, plugs are usually installed at both ends of the rotary screen and the inside of the rotary screen is filled with compressed air. One of the two plugs is usually fixed on the drive shaft, and the position of the other plug can be adjusted arbitrarily along the guide rail on the frame to adapt to different lengths of the rotary screen. In order to realize this adjustment function, the plug needs to be installed on a tailstock, which can move along the guide rail. As long as the tailstock is locked, the position...
