[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Reference Figure 1 、 Figure 3 and Figure 4 , an embodiment provided by the present utility model: a fixing jig for welding communication parts, including a bottom plate 1 for supporting a workpiece, a fixing component 2 for fixing the workpiece is arranged at the top end of the bottom plate 1. The fixing component 2 includes a sliding plate 21 for supporting the whole fixing component 2. The sliding plate 21 is slidably connected to the top end of the bottom plate 1. The sliding plate 21 can slide horizontally left and right at the top end of the bottom plate 1. A sliding rod 22 for guiding the movement of an extrusion plate 23 is penetrated and slidably connected to the left end of the sliding plate 21. A left end of the sliding rod 22 is fixedly connected to an extrusion plate 23 for extruding the workpiece. A bolt 26 for driving an extrusion block 27 to move is penetrated and threadedly connected to the top end of the extrusion plate 23. A bottom end of the bolt 26 is rotatably connected to an extrusion block 27 for extruding the workpiece. The extrusion block 27 is made of rubber material and will undergo elastic deformation when being extruded. A knob 28 for facilitating an operator to rotate the bolt 26 is fixedly connected to the top end of the bolt 26. An adjusting component 3 for fixing the sliding plate 21 is arranged at the front end of the bottom plate 1. The adjusting component 3 includes a support plate 36 for supporting the rotation of a rotating rod 31. The left end of the support plate 36 is rotatably connected to the rotating rod 31.

[0032] Reference Figure 2 - Figure 4, the adjusting assembly 3 further includes a moving plate 32 for driving the sliding plate 21 to move. The rear end of the moving plate 32 is fixedly connected to the front end of the sliding plate 21. When the moving plate 32 moves, the sliding plate 21 will also be driven to move synchronously. A spiral groove 34 for accommodating the ball block 33 is provided on the outer wall of the rotating rod 31, and a ball block 33 for driving the moving plate 32 to move is provided on the inner wall of the moving plate 32. The ball block 33 slides on the inner wall of the spiral groove 34. When the spiral groove 34 rotates, it will drive the moving plate 32 to move by squeezing the ball block 33. There are multiple groups of spiral grooves 34 and moving plates 32, and multiple groups of spiral grooves 34 and moving plates 32 are symmetrically arranged with the center line of the rotating rod 31 as the axis of symmetry. Since the two groups of spiral grooves 34 are symmetrically arranged, when the rotating rod 31 rotates, the two moving plates 32 will move in opposite directions. The left end of the support plate 36 is fixedly connected with a torsion spring 37 for driving the rotating rod 31 to rotate and reset. The left end of the torsion spring 37 is fixedly connected with a rotating ring 35 for driving the rotating rod 31 to rotate. The rotating ring 35 is fixedly connected to the outer wall of the rotating rod 31. When the rotating ring 35 rotates, the rotating rod 31 will also be driven to rotate synchronously. The front end of the bottom plate 1 is fixedly connected with a fixed sleeve 39 for accommodating the fixed block 310. The inner wall of the fixed sleeve 39 penetrates and is slidably connected with a fixed block 310 for fixing the rotating rod 31. The top end of the fixed block 310 is provided with an inclined surface. When the inclined surface is squeezed, the fixed block 310 will be forced to move forward. A fixed groove 38 for accommodating the fixed block 310 is provided on the outer wall of the rotating rod 31, and the fixed block 310 and the fixed groove 38 are adapted to each other. After the fixed block 310 is inserted into the inside of the fixed groove 38, the rotating rod 31 will not be able to rotate forward.

[0033] Referring to Figure 2 - Figure 4 , the front end of the fixed block 310 is fixedly connected with a fixed spring 312 for pushing the fixed block 310. The front end of the fixed spring 312 is fixedly connected to the inner wall of the fixed sleeve 39. When the rotating rod 31 rotates backward, it will drive the two moving plates 32 to move towards the middle position by squeezing the ball block 33 through the spiral groove 34. When the rotating rod 31 stops, the fixed spring 312 will push the fixed block 310 to make it snap into the inside of the fixed groove 38. The front end of the fixed sleeve 39 is fixedly connected with a connecting rod 311 for driving the fixed block 310 to move. The connecting rod 311 penetrates and is slidably connected to the front end of the fixed sleeve 39. By pulling the connecting rod 311, the fixed block 310 can be driven to move. The front end of the connecting rod 311 is fixedly connected with a dial block 313 for facilitating the operator to dial the connecting rod 311. The right end of the sliding rod 22 is fixedly connected with a closing cover 25 for closing the right end opening of the sliding rod 22. The left end of the closing cover 25 is fixedly connected with a compression spring 24 for pulling the closing cover 25. The left end of the compression spring 24 is fixedly connected to the right end of the sliding plate 21. The compression spring 24 will always pull the closing cover 25 to the left.

[0034] Working principle: When it is necessary to clamp the workpiece, you can first move a set of slides 21 to the middle position. The slide 21 will drive the rotating rod 31 to rotate backward through the moving plate 32 and the ball block 33. Since the two sets of spiral grooves 34 are symmetrically arranged, when the rotating rod 31 rotates, it will drive the two sets of moving plates 32 to move synchronously to the middle position by squeezing the ball block 33. The moving plate 32 will drive the slide 21 to move, and the slide 21 will drive the squeezing plate 23 to squeeze and fix the workpiece from the left and right directions. When the rotating rod 31 stops rotating, the fixing spring 312 will push the fixing block 310 to get into the fixing groove 38, so that the rotating rod 31 cannot rotate forward, thereby fixing the position of the slide 21, reducing the offset space of the workpiece, and increasing the processing accuracy.

[0035] When the workpiece is fixed in the left and right directions, the knob 28 can be rotated to drive the bolt 26 to rotate, so that the extrusion block 27 moves downward to squeeze the workpiece and fix the upper and lower positions of the workpiece. The workpiece can be fixed to the top of the base plate 1 through the combined action of the extrusion block 27 and the extrusion plate 23.

[0036] When the workpiece needs to be released, the bolt 26 needs to be rotated first to release the fixation of the extrusion block 27 on the workpiece. Then, the connecting rod 311 can be pulled by the shift block 313 to drive the fixing block 310 to move out of the fixing groove 38, thereby releasing the fixation of the rotating rod 31. At this time, the torsion spring 37 will pull the rotating ring 35 to rotate and reset the rotating rod 31. The rotating rod 31 drives the two sets of movable plates 32 to move outward, and the slide plate 21 will also move outward and reset under the action of the extrusion spring 24, so that the operator can easily remove the workpiece.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
