Description
Technical field
The invention belongs to car body welding technology field, especially relate to a kind of manual positioning mechanism for car body welding.
Background technology
In car body welding process, need to manually locate, former manual positioning mechanism as shown in Figure 1, 2, handgrip is mobile location of realizing alignment pin in the J-shaped groove of key seat, time has been grown, between handgrip and J-shaped groove, friction can produce wearing and tearing repeatedly, alignment pin is offset, produces the low problem of positioning precision, and key seat processing is relatively difficult.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of manual positioning mechanism for car body welding, and in structure, improvement to some extent, improves positioning precision.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of manual positioning mechanism for car body welding, comprise alignment pin, key seat and handgrip, alignment pin is stretched out or is retracted by moving of handgrip, also comprise the external bushing being connected with key seat and be located at the neck bush in key seat, described handgrip is located at one end of alignment pin, alignment pin is successively through external bushing, key seat, neck bush and handgrip, neck bush is fixedly connected with key seat, alignment pin overcoat has Compress Spring, the two ends of Compress Spring are connected between the side and neck bush of external bushing near alignment pin top, the corresponding stopping means cooperatively interacting that is provided with on key seat outside and handgrip, stopping means on handgrip is realized with the stopping means on key seat and is mutually engaged or separate by the movement of self and handgrip.
Further, described stopping means is be located at the L shaped limited block on handgrip and be located at the spacing groove on key seat, and described handgrip and L shaped limited block are fixed by screw, and L shaped limited block horizontally rotates on handgrip.Rotary handle, L shaped limited block and spacing groove diverge to, and press handgrip and go back to, and make L shaped limited block and the mutual interlock of spacing groove, and alignment pin stretches out, and plays positioning action.In the time that needs alignment pin is return, rotary handle, L shaped limited block and spacing groove diverge to, and rely on the elastic force of Compress Spring automatically alignment pin to be exited.
Further, described spacing groove comprises fixed part and hook body, between fixed part and key seat, is fixedly connected with, and described hook body mutually engages or separates with L shaped limited block.
Further, described key seat is rectangle, and its one end towards handgrip is provided with three stop screws, is located at respectively away from two edges of spacing groove one end and any one edge of close spacing groove one end.Three stop screws limit the rotating range of handgrip.
Advantage and good effect that the present invention has are: simple in structure; Reduce alignment pin and key seat friction, improve positioning precision; Utilize spring to make operation more laborsaving.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
As shown in Fig. 3～8, a kind of manual positioning mechanism for car body welding, comprise alignment pin 1, key seat 2, handgrip 3, external bushing 8, neck bush 5 and Compress Spring 4, external bushing 8 is connected with key seat 2, neck bush 5 is located in key seat 2, neck bush 5 is graphite copper sheathing, handgrip 3 is located at one end of alignment pin 1, alignment pin 1 is successively through external bushing 8, key seat 2, neck bush 5 and handgrip 3, alignment pin 1 is stretched out or is retracted by moving of handgrip 3, neck bush 5 is fixedly connected with key seat 2, alignment pin 1 overcoat has Compress Spring 4, the two ends of Compress Spring 4 are connected between the side and neck bush 5 of external bushing 8 near alignment pin 1 top, the corresponding stopping means cooperatively interacting that is provided with on key seat 2 outsides and handgrip 3, stopping means is be located at the L shaped limited block 7 on handgrip 3 and be located at the spacing groove 6 on key seat 2, handgrip 3 is fixing by screw 9 with L shaped limited block 7, L shaped limited block 7 can horizontally rotate by screw 9.
Spacing groove 6 comprises fixed part and hooks body, between fixed part and key seat 2, is fixedly connected with, and hooks body and mutually engages or separate with L shaped limited block 7.
