[0012] Technical effects and advantages of the utility model:

[0013] The utility model utilizes the design of a clamping jaw, a processing head, an anti-scratch component and a pushing component. When the processing head pushes and squeezes the riveted nut, the processing head drives the fixing ring to move synchronously, and the fixing ring drives the pushing block to squeeze the extrusion plate first. At this time, the processing head does not contact the clamping jaw. As the extrusion plate compresses the spring, when the processing head contacts the riveted nut, the clamping jaw is pushed to rotate under the action of the spring, so that the symmetrically arranged clamping jaws are opened, so that the processing head does not contact the top end of the clamping jaw, thereby achieving the anti-scratch effect of the top end of the clamping jaw.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-4The shown anti-scratch clamping tool for processing riveted nuts includes symmetrically arranged jaws 1, a mounting frame 2 for fixing the jaws 1 is arranged on the back of the jaws 1, a processing head 3 for processing riveted nuts is arranged on the top of the jaws 1, an anti-scratch component 7 for preventing the jaws 1 from being scratched is arranged on the top of the jaws 1, a pushing component 8 for pushing the anti-scratch component 7 is arranged on the bottom of the processing head 3, and the anti-scratch component 7 includes an extrusion plate 71 and a spring 72, the spring 72 is arranged at the top of the jaws 1, and the extrusion plate 71 is arranged at the top of the spring 72.

[0021] Specifically, a circular through groove is provided on one side of the front face of the clamping jaw 1, and a fixed round rod 4 is inserted and connected inside the circular through groove. One end of the fixed round rod 4 is fixedly connected to the front face of the mounting frame 2, and a torsion spring 5 is sleeved on the outer wall of one end of the fixed round rod 4. One end of the torsion spring 5 is fixedly connected to the bottom end of the clamping jaw 1, and the other end of the torsion spring 5 is fixedly connected to a fixing plate 6. The back side of the fixing plate 6 is fixedly connected to the front face of the mounting frame 2, and a second circular hole for inserting the fixed round rod 4 is provided on one side of the front face of the fixing plate 6. The cross-section of the clamping jaw 1 is L-shaped, and a limiting hole is provided on the other side of the front face of the fixing plate 6. The clamping jaw 1 is inserted and connected with the limiting hole, and the limiting hole is used to limit the range of rotation of the clamping jaw 1.

[0022] Furthermore, the clamping jaws 1 and the processing head 3 are the clamping parts and stamping parts of the riveted nuts of the existing hydraulic riveting machine. The clamping jaws 1 are symmetrically arranged at the two ends of the front side of the mounting frame 2. The two clamping jaws 1 are provided with clamping grooves for clamping the riveted nuts on the opposite sides. The inner wall of the circular through groove is a smooth inner wall, so that the clamping jaw 1 rotates around the fixed round rod 4. The back side of the top end of the fixed plate 6 is fixedly connected to the front side of the mounting frame 2 by welding, and the other end of the torsion spring 5 is fixedly connected to the inner wall of the fixed plate 6 by welding. One end of the torsion spring 5 is fixedly connected to the bottom end of the clamping jaw 1 by welding, so that when the clamping jaw 1 rotates away from the processing head 3, the torsion spring 5 will generate a restoring force, thereby driving the clamping jaw 1 to rotate toward the processing head 3. The end of the clamping jaw 1 close to the mounting frame 2 is inserted into the limiting hole, and the limiting hole only limits the range of rotation of the clamping jaw 1 toward the processing head 3, thereby keeping the clamping jaw 1 in a horizontal state without the extrusion of the pushing component 8.

[0023] Specifically, the top end of the clamping jaw 1 is fixedly connected to the bottom end of the spring 72 , and the top end of the spring 72 is fixedly connected to the bottom end of the extrusion plate 71 .

[0024] Furthermore, two springs 72 are symmetrically arranged on both sides of the bottom end of the squeezing plate 71 , and the top and bottom ends of the springs 72 are fixedly connected to the bottom end of the squeezing plate 71 and the top end of the clamping jaw 1 respectively by welding.

[0025] Specifically, the pushing assembly 8 includes a symmetrically arranged pushing block 82, the top of which is fixedly connected to a fixing ring 81 for installing the pushing block 82, a first circular hole is opened at the top of the fixing ring 81, the processing head 3 is connected with the first circular hole through an insertion, and the outer wall of the processing head 3 is fixedly connected with the inner wall of the first circular hole.

[0026] Furthermore, the first circular hole is fixedly connected to the outer wall of the processing head 3 by welding, and the top of the pushing block 82 is fixedly connected to the bottom end of the fixing ring 81 by welding. The pushing block 82 corresponds to the position of the extrusion plate 71. When the processing head 3 moves toward the direction close to the clamp 1, the processing head 3 drives the fixing ring 81, and the fixing ring 81 drives the pushing block 82 to move synchronously. The pushing block 82 will squeeze the extrusion plate 71, and the extrusion plate 71 squeezes the spring 72. As the processing head 3 continues to descend, the spring 72 is continuously compressed, so that when the processing head 3 contacts the rivet nut, the spring 72 pushes the clamp 1 to flip and rotate away from the processing head 3. Therefore, in the process of pressing down the processing head 3, the bottom end of the processing head 3 will not contact the top of the clamp 1 to protect the top of the clamp 1 from being scratched.

[0027] 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 substitutions for some of the technical features therein.
