Problems solved by technology
[0002] During the production process, it is necessary to move the workpiece to the designated working position. For some small workpieces, it can be done by hand in a safer production environment, but for large and medium-sized workpieces, especially in dangerous production environments (such as radiation, etc.) Under certain conditions, it is extremely difficult and dangerous to realize it manually by hand; some current fixtures can only meet the requirements of pushing or pulling, and there is no self-locking function

Embodiment Construction
[0015] In order to describe the technical content and structural features of the present invention in detail, further description will be given below in conjunction with the implementation and accompanying drawings.
[0016] see Figure 1 to Figure 4 , the push-pull self-locking fixture 100 of the present invention is used for pushing and pulling large and medium-sized workpieces 200 with vertical cylindrical convex pins 210 in hazardous environments. The push-pull self-locking fixture 100 includes a fixing plate 10 , a clamping mechanism 20 and a self-locking mechanism 30 built in the fixing plate 10 . The fixed plate 10 has a gap 11 along the direction from the left end to the right end of the fixed plate 10. Specifically, in this embodiment, the fixed plate 10 includes an upper fixed plate 12, a lower fixed plate 13 and a guide plate 14, The upper fixing plate 12 and the lower fixing plate 13 are arranged in parallel to form a receiving cavity 15, the receiving cavity 15 m...

The invention discloses a push-and-pull self-locking clamp, which comprises a fixing plate, a clamping mechanism arranged in the fixing plate and a self-locking mechanism, wherein a gap is formed on the edge of the fixing plate; the clamping mechanism comprises two clamping pieces; the two clamping pieces are pivoted in the fixing plate, and a clamping region corresponding to the gap is formed between the two clamping pieces; one end of each clamping piece stretches into the gap, and the other end of each clamping piece is in elastic connection with the fixing plate; the self-locking mechanism is positioned between the two clamping pieces, and comprises a connecting pin, a guide rod and two self-locking rods; one end of the guide rod is jointly pivoted with one end of one self-locking rod and one end of the other self-locking rod through the connecting pin; one end of the guide rod can be arranged on the fixing plate along a forming direction of the gap in a sliding mode; the other end of one self-locking rod is pivoted on one clamping piece; and the other end of the other self-locking rod is pivoted on the other clamping piece. The push-and-pull self-locking clamp can integrate pushing and pulling functions and has a self-locking function so as to be suitable for pushing and pulling medium and large workpieces in a dangerous production environment.
Description
technical field [0001] The invention relates to a clamp, in particular to a push-pull self-locking clamp. Background technique [0002] During the production process, it is necessary to move the workpiece to the designated working position. For some small workpieces, it can be done by hand in a safer production environment, but for large and medium-sized workpieces, especially in dangerous production environments (such as radiation, etc.) Under certain conditions, it is extremely difficult and dangerous to realize it manually by hand; some current fixtures can only meet the requirements of pushing or pulling, and have no self-locking function. [0003] Therefore, there is an urgent need for a push-pull self-locking fixture that can integrate push and pull and has a self-locking function to overcome the above-mentioned defects. Contents of the invention [0004] The object of the present invention is to provide a push-pull self-locking fixture which can integrate push and ...
