Along with the clamping action hooking pawl clamping device 4, the fixing reliable, accurate positioning of lower fork and hook pawl；Due to being provided with upper fork
Board 52 and upper fork holding frame 54, carry out supporting positioning by upper fork support plate 52 to upper fork, by upper fork holding frame 54 to upper
Fork is gripped, the fixation of so upper fork, reliability；In addition, upper fork support plate 52 is relative with lower fork support plate 61
Angle is to determine, the angle between therefore upper fork and lower fork can also determine, and degree of accuracy is high, in welding process also not
It is susceptible to displacement, deformation.In this utility model, on automatic welding tooling welding hook pawl with fork junction, five lead to
With the junction of the junction of lower fork, the five logical junctions with standpipe and standpipe and upper fork, with respect to prior art it is not necessary to
Welding tooling, with fork and lower fork in external welding, accordingly, it is capable to improve efficiency, can improve the degree of accuracy of welding simultaneously.
Hook pawl clamping device 4 of the present utility model, can not only be positioned moreover it is possible to reliably be clamped to hooking pawl, with
When hook pawl easy to disassemble.
In the present embodiment, pitch by upper fork rest pad 523 supporting, fork can be avoided directly to connect with upper fork support plate 52
Touch, the effect of fork in protection can be played.Due to using the second waist type groove 521, as long as unclamping the second bolt 522, can adjust
The position of fork rest pad 523, to be applied to the welding ibid do not pitched.
Lower fork is supported by lower fork rest pad 613, lower fork can be avoided directly to contact with lower fork support plate 61, protection can be played
The effect of lower fork.Due to using the 3rd waist type groove 611, as long as unclamping the 3rd bolt 612, lower fork rest pad 613 can be adjusted
Position, to be applied to the welding of different lower forks.
