Description
Technical field
The utility model belongs to car body welding technology field, especially relates to a kind of manual positioning mechanism for car body welding.
Background technology
Need to manually locate in car body welding process, former manual positioning mechanism as shown in Figure 1, 2, hand is the location realizing alignment pin mobile in the J-shaped groove of key seat, time has been grown, between hand handle and J-shaped groove, friction can produce wearing and tearing repeatedly, alignment pin is offset, produces the problem that positioning precision is low, and key seat processing is relatively difficult.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of manual positioning mechanism for car body welding, and structure improves to some extent, improves positioning precision.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of manual positioning mechanism for car body welding, comprise alignment pin, key seat and hand handle, alignment pin is stretched out by moving of hand handle or is retracted, also comprise the external bushing be connected with key seat and the neck bush be located in key seat, described hand is the one end being located at alignment pin, alignment pin is successively through external bushing, key seat, neck bush and hand handle, neck bush is fixedly connected with key seat, alignment pin overcoat has Compress Spring, the two ends of Compress Spring are connected to external bushing near between the side and neck bush on alignment pin top, outside and the hand of key seat is correspondingly provided with the stopping means cooperatively interacted upper, hand realizes upper stopping means mutually to engage with the stopping means on key seat or be separated by self and the movement of hand handle.
Further, described stopping means is be located at hand upper L shape limited block and the spacing groove be located on key seat, and described hand handle is fixed by screw with L shape limited block, and L shape limited block horizontally rotates on hand handle.Rotary handle, L shape limited block and spacing groove diverge to, and by setting about and going back to, L shape limited block is engaged mutually with spacing groove, and alignment pin stretches out, and plays positioning action.When needs alignment pin is return, rotary handle, L shape limited block and spacing groove diverge to, and rely on the elastic force of Compress Spring automatically to be exited by alignment pin.
Further, described spacing groove comprises fixed part and hooks body, and be fixedly connected with between fixed part with key seat, described hook body mutually engages with L shape limited block or is separated.
Further, described key seat is rectangle, and its one end towards hand handle is provided with three stop screws, is located at two edges away from spacing groove one end and any one edge near spacing groove one end respectively.The rotating range of three stop screw opponent handles limits.
The advantage that the utility model has and good effect are: structure is simple; Reduce alignment pin and key seat friction, improve positioning precision; Spring is utilized to make operation more laborsaving.

Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Fig. 3 ~ 8, a kind of manual positioning mechanism for car body welding, comprise alignment pin 1, key seat 2, hand is 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, hand is located at one end of alignment pin 13, alignment pin 1 is successively through external bushing 8, key seat 2, neck bush 5 and hand are 3, alignment pin 1 by hand 3 move and stretch out or retract, 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 to external bushing 8 near between the side and neck bush 5 on alignment pin 1 top, key seat 2 outside and hand are provided with corresponding on 3 the stopping means cooperatively interacted, stopping means is be located at hand the L shape limited block 7 on 3 and the spacing groove 6 be located on key seat 2, hand is fixed by screw 9 with L shape limited block 73, L shape limited block 7 can be horizontally rotated by screw 9.
Spacing groove 6 comprises fixed part and hooks body, is fixedly connected with between fixed part with key seat 2, hooks body and mutually engages with L shape limited block 7 or be separated.
Key seat 2 is rectangle, and it is provided with three stop screws 10 towards hand one end of 3, is located at two edges away from spacing groove 6 one end and any one edge near spacing groove 6 one end respectively.Three stop screw 10 opponents limit the rotating range of 3.As shown in Figure 7, dotted line is that hand is the rotate path of 3.
The course of work of the present utility model: rotary handle 3, L shape limited block 7 and spacing groove 6 diverge to, by setting about 3 and going back to, L shape limited block 7 is engaged mutually with spacing groove 6, and alignment pin 1 stretches out, and plays positioning action.When needs alignment pin 1 is return, rotary handle 3, L shape limited block 7 and spacing groove 7 diverge to, and rely on the elastic force of Compress Spring 4 automatically to be exited by alignment pin 1.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and all should still belong within patent covering scope of the present utility model.
