Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 to 3, a riveting tool for improving the quality of riveting processing includes a fixing fixture 10 and a blind rivet 20 that is fixed with the aid of the fixing fixture 10, and the fixing fixture 10 and the blind rivet are used in cooperation with a first workpiece 30 and a second workpiece 40 that are required to be riveted during the riveting processing.

Referring to fig. 2 and 3, the fixing clamp 10 includes a fixing frame 11, a positioning rod 12, two sets of connecting frames 13, and two sets of clamping frames 14. The position-adjusting rod 12 can be adjusted and moved by a worker so as to be movably arranged in the middle part in the fixing frame 11. The middle parts of the positioning rods 12 are respectively and rotatably connected with two groups of connecting frames 13, one end of each group of connecting frames 13 far away from the positioning rods 12 penetrates through the fixing frame 11 and is rotatably connected with the clamping frames 14, and the middle parts of the two groups of clamping frames 14 are rotatably connected with the corners of the fixing frame 11 by utilizing pin shafts. The positioning rod 12 can push the two groups of connecting frames 13 to deflect symmetrically when moving, and the connecting frames 13 push the clamping frames 14 connected with the connecting frames to deflect by taking the pin shafts as the rotation center shafts, so that the angle state of the clamping frames 14 connected with the positioning rod 12 is adjusted by the connecting frames 13 when moving, and the blind rivets 20 can be clamped after the two groups of clamping frames 14 deflect oppositely.

In this embodiment, the fixing frame 11 may include a hollow frame body 111 and two sets of suction cups 112. The frame 111 may be a hollow frame structure formed by metal die casting or plastic injection molding. The two opposite sides of the frame 111 are provided with movable slots 113, and the movable slots 113 are used for preventing the frame 111 from blocking the deflection of the connecting frame 13. Two groups of suckers 112 are fixed at the corner of one side of the frame 111 far away from the clamping frame 14, and the suckers 112 can be permanent magnet blocks or soft rubber suckers. So that the fixing frame 11 can utilize the suction of the suction disc 112 to the first workpiece 30 when in use, so that the fixing frame 11 is temporarily fixed without the need of a worker to hold the fixing frame all the time. When the sucker 112 adopts permanent magnet blocks, magnetic force can be utilized to absorb metal workpieces; when the rubber suction cup is adopted, the fixing frame body 111 can be adsorbed by utilizing the negative pressure of the contact surface of the rubber suction cup and the rubber suction cup through extrusion of the rubber suction cup.

In the present embodiment, the positioning rod 12 includes a positioning seat 121, a return spring 122, a rod 123, and a pressing screw 124. The positioning seat 121 is fixed on the inner wall of the frame 111, and a cross section of a side of the positioning seat 121 facing the frame 111 is provided in a circular shape. Both ends of the return spring 122 are fixedly connected to opposite sides of the positioning seat 121 and the rod body 123, respectively. The pressing screw 124 is in threaded connection with the frame 111, and the pressing screw 124 and the rod body 123 are coaxially distributed. One end of the pressing screw 124 extending into the frame 111 contacts with the end of the rod 123, so that when the pressing screw 124 is screwed into the frame 111, the rod 123 can be pushed to compress the movement of the return spring 122; when the pressing screw 124 is unscrewed away from the frame 111, the return spring 122 deforms to push the rod body 123 toward the pressing screw 124 and maintains contact with the pressing screw 124. The inner diameter of the positioning seat 121 is matched with the diameter of the end part of the rod body 123, and the rod body 123 slides through the gap in the middle of the positioning seat 121, so that the rod body 123 can be guided by the positioning seat 121 in the moving process, and the rod body 123 is prevented from shifting when moving.

In this embodiment, a clamping piece 141 is fixed on one side of the clamping frame 14 near the blind rivet 20, and the height of the clamping piece 141 is similar to the height of the end of the blind rivet 20, so that the clamping piece 141 can prop against the blind rivet 20 after contacting with the blind rivet 20.

During the rivet pulling process, holes matched with the blind rivets are formed in the first workpiece 30 and the second workpiece 40 which are required to be riveted and fixed in advance, and then the blind rivets 20 are inserted from the lower side of the first workpiece 30 to the upper side after the holes formed in the first workpiece 30 and the second workpiece 40 are aligned. The user may then place the fixture 10 under the first workpiece 30 and cause the fixture 10 to be secured to the surface of the first workpiece 30 using suction cups 112. Then, the pressing screw 124 is screwed into the frame 111, so that the angle state of the clamping frames 14 connected with the positioning rod 12 is adjusted by the connecting frame 13 when the positioning rod moves, and the blind rivets 20 can be clamped after the two groups of clamping frames 14 deflect oppositely, so that the blind rivets are kept vertical. The operator may then perform a rivet extraction operation with the rivet extractor from above the second workpiece 40. After the riveting process is completed, the user unscrews the pressing screw 124 and pulls the frame 111 downward, and then the fixing jig 10 can be detached.

In all the above mentioned solutions, in which the connection between two components can be chosen according to the actual situation, a welded, bolt-and-nut-fitted connection, a bolt-or-screw connection or other known connection means, which are not described in detail herein, where reference is made to a written fixed connection, the preferred consideration is welding, although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that numerous variations, modifications, substitutions and alterations can be made to these embodiments without departing from the principle and spirit of the utility model, the scope of which is defined by the appended claims and their equivalents.
