Description

Technical Field

[0001] The present application relates to the technical field of automobile parts processing, and in particular to a rivet auxiliary positioning fixture. Background Art

[0002] In the riveting process, external tension causes the riveted parts to plastically deform, clamping the base material at the deformed area to achieve a reliable connection. With the rapid development of the automotive industry, riveting is increasingly used in automotive manufacturing. Whether in body construction or internal parts assembly, riveting can be used to connect different parts. Compared with traditional welding and bolting, riveting technology achieves a stronger bond at the connection point by connecting materials through plastic deformation. This high-strength connection ensures that the vehicle's structure remains stable and less susceptible to deformation or damage when subjected to various external forces and vibrations during driving.

[0003] In automotive products, some small parts are connected by rivets. For example, the shock-absorbing reinforcement bracket of the car tailgate needs to be connected by rivets. If employees are asked to hold the parts by hand to rivet, the positioning accuracy of the parts will be unstable, and the riveting impact will cause the bracket to shift, resulting in shock absorption failure and abnormal noise.

[0035] like Figure 1 As shown, this embodiment provides a rivet auxiliary positioning device, including:

[0036] Equipment body 1;

[0037] A support block 2 is installed at the bottom of the harness body 1, and the relative position between the support block 2 and the harness body 1 is adjustable;

[0038] A first clamping block 3 is mounted on the side of the harness body 1;

[0039] The second clamping block 4 is installed on the side of the harness body 1 . A clamping space 5 is formed between the second clamping block 4 and the first clamping block 3 , and the size of the clamping space 5 is adjustable.

[0040] In some embodiments, the support block 2, the first clamping block 3, and the second clamping block 4 are all mounted on the harness body 1. Therefore, when the relative position between the support block 2 and the harness body 1 is adjusted, the position change of the harness body 1 will simultaneously drive the position change of the first clamping block 3 and the second clamping block 4, which is equivalent to adjusting the position height of the clamping space 5.

[0041] By setting the support block 2, it is possible to facilitate the placement of the entire positioning harness in the work scene and improve its stability when placed in application. By adjusting the relative position between the support block 2 and the harness body 1, the position height of the harness body 1 can be adjusted, and the position height of the clamping space 5 can be adjusted.

[0042] By setting the first clamping block 3 and the second clamping block 4, the clamping space 5 formed therebetween can be used to clamp parts, thereby facilitating subsequent riveting operations; and by adjusting the size of the clamping space 5, it can be adapted to the clamping applications of parts with more thickness sizes, and the scope of use can be wider.

[0043] As an application example, the support block 2 is provided with a bending portion 21, and the bending portion 21 is mounted on the bottom of the harness body 1 through a first fastener 22;

[0044] An accommodating space 23 is formed between the bottom end surface of the bent portion 21 and the bottom end surface of the supporting block 2 , and the head of the first fastener 22 falls in the accommodating space 23 .

[0045] In some embodiments, the first fastener 22 is configured as a bolt. During installation, the first fastener 22 sequentially penetrates the bent portion 21 and the harness body 1 from below the bent portion 21 , and after being tightened, the support block 2 is installed on the harness body 1 .

[0046] In some embodiments, the height of the accommodating space 23 in the vertical direction is greater than the height of the head of the first fastener 22, so that the first fastener 22 is completely located in the accommodating space 23 when installed, thereby avoiding the setting of the first fastener 22 affecting the supporting performance of the support block 2.

[0047] As an application example, a first adjusting piece 24 is provided between the bending portion 21 and the harness body 1 .

[0048] In some embodiments, the number of the first adjustment pieces 24 is not unique, that is, the first adjustment pieces 24 can be provided in one piece or in multiple pieces.

[0049] In some embodiments, the thickness of the first adjustment sheet 24 has various specifications.

[0050] During use, the relative position between the bending portion 21 and the harness body 1 can be adjusted by changing the number of the first adjusting pieces 24 or the thickness of the first adjusting pieces 24 , which makes use more convenient.

[0051] As an application example, the first clamping block 3 is detachably mounted on the bottom of the side of the harness body 1;

[0052] A rivet plane pressing block 31 is detachably mounted on the front end of the first clamping block 3 .

[0053] The rivet plane pressing block 31 can be used to press the rivet planes of the riveted part and the main part, thereby facilitating the rivet operation.

[0054] As an application example, the second clamping block 4 includes a connecting portion 41 and a clamping portion 42 , and the connecting portion 41 is mounted on the top of the harness body 1 through a second fastener 43 ;

[0055] The clamping space 5 is formed between the bottom end surface of the clamping portion 42 and the top end surface of the first clamping block 3 .

[0056] In some embodiments, the second fastener 43 is configured as a bolt. During installation, the second fastener 43 sequentially penetrates the connecting portion 41 and the harness body 1 from above the connecting portion 41 , and after being tightened, the second clamping block 4 is installed on the harness body 1 .

[0057] As an application example, a second adjustment piece 44 is provided between the connecting portion 41 and the harness body 1 .

[0058] In some embodiments, the number of the second adjustment pieces 44 is not unique, that is, the second adjustment pieces 44 can be provided in one piece or in multiple pieces.

[0059] In some embodiments, the thickness of the second adjustment sheet 44 has various specifications.

[0060] During use, by changing the number of the second adjustment pieces 44 or the thickness of the second adjustment pieces 44 , the relative position between the connecting portion 41 and the harness body 1 and the size of the clamping space 5 can be adjusted, making use more convenient.

[0061] As one application example, in order to facilitate the use of the first fastener 22 and the second fastener 43, a U-shaped bayonet 441 is provided on the first adjusting piece 24 and the second adjusting piece 44, so that the first adjusting piece 24 and the second adjusting piece 44 can be installed in a plug-in manner to avoid the need for the first fastener 22 and the second fastener 43 to be disengaged as a whole when increasing or decreasing the first adjusting piece 24 and the second adjusting piece 44, which will be more convenient to use.

[0062] As an application example, magnetic elements are provided in the support block 2 , the first clamping block 3 , and the second clamping block 4 .

[0063] In some embodiments, the magnetic element may be provided only on the support block 2 to improve the placement stability of the entire positioning fixture.

[0064] In some embodiments, the magnetic element may be provided only in the first clamping block 3 and / or the second clamping block 4 to improve the clamping stability of the clamped parts.

[0065] In some embodiments, the magnetic attraction member is configured as a magnet.

[0066] The provision of the magnetic element can improve the stability of the entire positioning device during use and prevent the device from accidentally falling during use.

[0067] As an application example, a positioning pin 11 is provided at the front end of the harness body 1 .

[0068] By providing the positioning pins 11, the entire positioning fixture can be easily adapted to a specific location in the working environment, thereby improving positioning accuracy and working efficiency.

[0069] As an application example, a handle 12 is detachably mounted on the rear end of the harness body 1 .

[0070] The handle 12 is provided to facilitate the operator to hold and use the positioning device, thereby facilitating the manipulation of the entire positioning device.
