Lock tongue and lock seat of locking mechanism of van and manufacturing method of lock tongue and lock seat
The invention provides a spring bolt and a lock seat of a locking mechanism of a van and a manufacturing method of the spring bolt and the lock seat, the spring bolt is provided with a ball socket and a ball, the lock seat is provided with a groove arc raceway, the contact part of the lock seat and the spring bolt is changed into the groove arc raceway from an existing convex slide way, the diameter of the groove arc raceway is larger than that of the ball, and the ball socket and the lock seat are arranged in the groove arc raceway. And the groove arc raceways are used as raceways of the balls. A ball is arranged at the contact part of a lock tongue and a lock seat, so that the lock tongue is difficult to manufacture, and the lock tongue can be manufactured by drilling and grinding and adopting an existing precision casting process and a manufacturing method for stamping a curled spherical surface, and the simple and ingenious method is as follows: when the precisely cast lock head is assembled with the ball on a punching machine, the lock head is put into a working platform of the punching machine to be fastened, and then the ball is inserted into the working platform of the punching machine; the ball is placed in the ball socket of the spring bolt, then the punch with the arc punches down, the upper portion of the ball socket is spherically curled, and the ball can be sealed in the ball socket with a slight gap.
本发明提供了一种厢式货车的锁闭机构的锁舌和锁座及其制造方法，包括带有球窝和滚珠的锁舌和带凹槽圆弧滚道的锁座，在锁座与锁舌的接触部分由现在的凸起滑道改为凹槽圆弧滚道，该凹槽圆弧滚道的直径较滚珠的直径要大，凹槽圆弧滚道作为滚珠的滚道。由于在锁舌与锁座接触部位设置一个滚珠，致使锁舌制造困难，通过钻研，采用现有的精铸工艺和冲压卷曲球面的制造方法即可完成，简单巧妙的方法为：在精铸出来的锁头在冲床进行与滚珠进行组装时，将锁头放入冲床的工作平台紧固后，再将滚珠放入锁舌的球窝中，此后，带圆弧的冲头冲下来，将球窝上部进行球形卷曲，可将滚珠略带间隙地封闭在球窝中。
