Background
In the assembly welding production process of the automobile body, especially in the assembly process of the adjusting line harness, due to the requirement of specific occasions, the positioning mechanism needs to use a telescopic pin for positioning.
Where a telescopic pin is generally used, a double-guide-rod telescopic cylinder is generally used. Therefore, workers need to design the air path, the limiting mechanism, the control valve plate and the like. Still need design handle when the manual bolt of needs because can cause the mechanism complicated and trivial details, difficult operation has increased the maintenance cost, promotes equipment failure rate.
Simple manual latch solutions are also commonly used by current workers. However, the manual bolt scheme does not fully consider the condition that the positioning pin is loosened, so that the working performance of the bolt is unstable, the risk of movement exists, and the application occasions are limited.

According to the optimized scheme, a plurality of positioning holes are formed in the base, and internal threads are formed in each positioning hole; an axial groove corresponding to the positioning hole is arranged on the positioning pin; the locating hole has the anti-rotation pin through female connection, and the medial extremity of anti-rotation pin corresponds axial recess.
According to the optimized scheme, the total number of the plunger holes and the positioning holes on the base is four, and the plunger holes and the positioning holes are alternately distributed.
According to the optimized scheme, the upper end part of the positioning pin is provided with a threaded column, and the threaded column is in threaded connection with a handle.
According to the optimized scheme, a cover plate is arranged between the lower portion of the positioning pin and the lower end face of the base, and the positioning pin penetrates through the cover plate.
Due to the adoption of the technology, compared with the prior art, the invention has the beneficial effects that:
the invention realizes the manual positioning of the positioning pin by utilizing the base, the ball plunger and the anti-rotation pin, has simple structure and easy operation, can meet the positioning requirement, can effectively prevent the positioning pin from moving back and forth, and has good stability.
Drawings
FIG. 1 is a schematic overall structure diagram of an embodiment of the present invention;
fig. 2 is a schematic cross-sectional structure diagram according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
As shown in fig. 1-2, the anti-shifting manual latch mechanism includes a positioning pin 1, a base 2 is disposed at a lower portion of the positioning pin 1, and the positioning pin 1 penetrates through the base 2.
And bushings 4 corresponding to the positioning pins are respectively arranged on two sides of the base 2. And a plunger hole 10 is arranged on the base 2, and an annular groove 8 corresponding to the plunger hole 10 is arranged on the positioning pin 1. An internal thread is arranged in the plunger hole 10, the plunger hole is connected with a ball plunger 5 through the internal thread, and the end part of the inner side of the ball plunger 5 corresponds to the annular groove 8.
The base is provided with positioning holes 9, and each positioning hole 9 is internally provided with an internal thread. The positioning pin 1 is provided with an axial groove corresponding to the positioning hole. The locating hole has the anti-rotation pin 6 through female connection, and the medial extremity of anti-rotation pin 6 corresponds the axial recess.
According to the requirement of actual work, the total number of the plunger holes and the positioning holes on the base is four, and the plunger holes and the positioning holes are alternately distributed.
The upper end of locating pin is provided with screw thread post 11, and screw thread post 11 threaded connection has handle 7. And a cover plate 3 is arranged between the lower part of the positioning pin and the lower end surface of the base, and the positioning pin penetrates through the cover plate.
When the positioning pin is used, the positioning pin moves to a proper position, the ball plunger and the anti-rotation pin are unscrewed, the ball plunger clamps the position of the annular groove, and the anti-rotation pin corresponds to the axial groove in the positioning pin. The purpose of the anti-rotation pin is to prevent the rotation of the positioning pin so that the positioning pin can only move in the front-back direction. The positioning pin is provided with an annular groove, so that the positioning pin can be just clamped by the ball plunger in the extending and retracting states of the positioning pin, and the front and back movement of the positioning pin is prevented.
The invention realizes the manual positioning of the positioning pin by utilizing the base, the ball plunger and the anti-rotation pin, has simple structure and easy operation, can meet the positioning requirement, can effectively prevent the positioning pin from moving back and forth, and has good stability.
