Technical Field

[0001] The utility model relates to the technical field of bracket fixing, in particular to a fixing device for an automobile bracket assembly. Background Art

[0002] Various brackets are used in automobile mechanical structures. For brackets with more complex structures, multiple brackets are generally used to assemble and fix them to form a complex bracket assembly. The bracket assembly is generally fixed by welding or riveting. For the riveting fixation method, refer to Figure 1 In the prior art, when riveting more than three components, the first component and the second component are generally first inserted together through rivets, and then supported on a support column. Thereafter, pressure is applied by a press to deform the rivet to complete the riveting work of the first component. Thereafter, the orientation of the first component is reversed, and the first component and the third component are inserted together through rivets, and then placed on the support column again, and pressure is applied by a press again to complete the riveting of the first component and the third component. This riveting method has very complicated operation steps and relatively low work efficiency. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Reference Figure 2-Figure 4A fixing device for an automobile bracket assembly includes a working platform 1, a support column 7, and a press 9. The upper end of the support column 7 has a first abutting portion 8 and a second abutting portion 18 arranged opposite to each other on the left and right. The press 9 is arranged on the working platform 1 and is located on the side of the first abutting portion 8 away from the second abutting portion 18. A second rivet pressing head 17 is fixedly installed on the working platform 1 on the side of the second abutting portion 18 away from the first abutting portion 8. The support column 7 is slidably connected to the working platform 1, and the support column 7 can slide along the telescopic direction of the press 9.

[0019] When using this device, refer to Figure 2 , through the first rivet 12, the left side of the second part 13 is connected to the first part 11, and through the second rivet 14, the right side of the second part 13 is connected to the third part 15, and then supported above the support column 7, refer to Figure 3 , so that the first rivet 12 is located between the first riveting head 10 and the first abutment portion 8, and the second rivet 14 is located between the second riveting head 17 and the second abutment portion 18, refer to Figure 4 , and then start the press 9. Since the support column 7 can slide along the telescopic direction of the press 9, when the press 9 pushes the first riveting head 10 to move to the right, the entire support column 7 moves to the right under the conduction of the thrust, so that the first rivet 12 and the second rivet 14 are clamped between the first riveting head 10 and the second riveting head 17. As the force of the press 9 is applied, the first rivet 12 and the second rivet 14 are deformed to achieve the riveting purpose. The device can complete the riveting action of the first component 11 and the second component 13, and the second component 13 and the third component 15 through the thrust action of a press 9. There is no need to repeatedly adjust the position of each component. The operation is simple and the work efficiency is effectively improved.

[0020] Along the sliding direction of the support column 7, a first spring 2 is connected between the support column 7 and the working platform 1. The first spring 2 can make the support column 7 approach the press 9. When the riveting is completed, the press 9 shrinks to the left. Under the tension of the first spring 2, the support column 7 is reset, which is convenient for the next riveting process.

[0021] To reduce the difficulty of operation, refer to Figure 1 、 Figure 2 The first abutment portion 8 has a first sliding guide groove at one end close to the press 9, and / or the second abutment portion 18 has a second sliding guide groove at one end close to the second riveting head 17. The sliding guide grooves are provided so that the first rivet 12 can slide into the first sliding guide groove and the second rivet 14 can slide into the second sliding guide groove, thereby facilitating the preliminary positioning of the rivets.

[0022] A support block 16 that can be adjusted up and down is provided at the top of the support column 7. By adjusting the support block 16 up and down, the second component 13 is supported on the support block 16. For example, the support block 16 is threadedly connected to the support column 7, and the height of the support block 16 is adjusted by rotating the support block 16 under the action of the thread.

[0023] refer to Figure 2 、 Figure 3 In order to reduce the difficulty of operation, a supporting platform is provided on each side of the supporting column 7. The supporting platform includes a first bracket 3 installed on the supporting column 7. Two symmetrically arranged clamping blocks 6 are slidably connected to the upper part of the first bracket 3. A second spring 5 is connected between the clamping block 6 and the first bracket 3. The rivet is slipped into the limited sliding guide groove, and the first component 11 is clamped between the two clamping blocks 6 on the left, and the third component 15 is clamped between the two clamping blocks 6 on the right. In this way, the second component 13 is finally supported by the supporting block 16, and the first component 11 and the third component 15 are respectively supported by the supporting platform, so that after the support of each component is completed, it is more convenient to perform pressure riveting.

[0024] Since the first component 11 and the third component 15 may be at different heights, in order to improve adaptability, the support platform includes a height adjustment plate 4 fixed to the clamping block 6. The height adjustment plate 4 is fixed to the support column 7 by bolts. The support column 7 has several threaded holes for mounting bolts. The support height is changed by adjusting the height of the first bracket 3 up and down.

[0025] The above is only a preferred specific implementation method of the present invention, but the scope of protection of the present invention is not limited to this. Any technical solution, conception, and design obtained by equivalent replacement or modification of the technical solution and utility model concept of the present invention by any technical personnel familiar with the technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
