fig. 2 is a detailed view of the pneumatic locking device of the present utility model.
In the figure: 1. a tailstock body; 17. the second locking block; 23. a center; 24. a hydraulic cylinder; 25. a tailstock tube; 26. a pneumatic locking device; 29. a first locking block; 32. a thin cylinder.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples:
referring to fig. 1 to 2, the present utility model provides a technical solution:
the pneumatic locking tailstock comprises a tailstock body 1 and a tailstock barrel 25 positioned on the tailstock body 1, wherein a hydraulic cylinder 24 is arranged at one end of the tailstock barrel 25, a center 23 is arranged at the other end of the tailstock barrel 25, the center 23 is ejected out of the tailstock barrel 25 through the transmission of the hydraulic cylinder 24, and the tailstock barrel 25 is locked through a pneumatic locking device 26 vertically arranged at one side of a cutter tower of the tailstock barrel 25.
Specifically, the pneumatic locking device 26 includes a thin cylinder 32, a first locking block 29, and a second locking block 17, where the first locking block 29 and the second locking block 17 are installed on a piston rod of the thin cylinder 32, the pneumatic locking device 26 is vertically installed on the tailstock barrel 25, and the thin cylinder 32 drives the first locking block 29 and the second locking block 17 located on the piston rod to lock the tailstock barrel 25.
Specifically, when the pneumatic locking device 26 is locked, the locking force of the first locking block 29 is downward, and the locking force of the second locking block 17 is upward, so that kinetic energy input by the thin air cylinder 32 is efficiently transmitted, the clamping and loosening time is shortened, the locking tailstock tube 25 is maximized, redundant intervals are eliminated, and the working efficiency is improved.
