Description
Technical Field
[0001] The utility model relates to the technical field of vehicle part processing, and particularly relates to a processing tool for a rear mount bracket. Background Art
[0002] The rear mount bracket is a structure commonly used in various vehicles. It can be divided into left and right brackets or upper and lower brackets according to position, and is usually in a symmetrical relationship. The left and right rear mount brackets are special-shaped parts and are not planar structures. Their structures are generally formed by connecting several surface structures that are not in the same plane. In order to meet the functional requirements, different surfaces are connected at a certain angle, and each surface is provided with an edge. Holes need to be processed and drilled on each surface, so it is divided into multiple processing procedures.
[0003] The rear mount bracket has high requirements for processing accuracy, and the allowable deviation is only a few tenths of a millimeter. When drilling holes on each surface of the rear mount bracket, it is difficult to clamp and position, the clamping is not firm, and the positioning is inaccurate. During drilling, the position of the rear mount bracket is likely to shift, resulting in the deviation of the hole opening position or too large hole opening deviation, affecting the drilling accuracy, low qualified rate of the processed parts, high unqualified rate, affecting the production efficiency, wasting raw materials, and affecting the economic benefits. Summary of the Utility Model
[0004] In order to solve the problems of difficult clamping and inaccurate positioning during drilling of the rear mount bracket, which in turn affect the drilling accuracy, the utility model provides a processing tool for a rear mount bracket that can firmly clamp and accurately position the rear mount bracket and has high drilling accuracy.
[0005] To solve the above technical problems, the utility model includes a bottom plate. At least two positioning members for positioning the rear mount bracket are provided on the bottom plate. A pressing plate assembly for fixing the rear mount bracket is also provided on the bottom plate. Its structural feature is that: the pressing plate assembly includes a first pressing plate assembly for fixing the horizontal part of the rear mount bracket and a second pressing plate assembly for fixing the connecting part of the rear mount bracket. A side anti-deviation assembly for preventing the small end of the rear mount bracket from deviating to one side under the impact force of drilling is also provided on the bottom plate. The side anti-deviation assembly is arranged on the other side opposite to the drilling side of the small end and abuts against the side wall of the small end.
[0006] After adopting the above structure, the position of the rear mounting bracket is positioned by positioning members. There are at least two positioning members, which can accurately position the position of the rear mounting bracket; the first pressing plate assembly clamps and fixes the horizontal part of the rear mounting bracket, and the second pressing plate assembly clamps and fixes the connecting part of the rear mounting bracket. Under the combined action of the first pressing plate assembly and the second pressing plate assembly, the rear mounting bracket is firmly clamped and fixed; on the other side opposite to the drilling side of the small end, there is a side anti-offset assembly. The side anti-offset assembly abuts against the side wall of the small end. When drilling the hole of the small end, the small end will deflect towards the side anti-offset assembly under the push of the drilling force. The side anti-offset assembly abuts against the side wall of the small end, playing a role in hindering the deflection of the small end and improving the drilling accuracy.
[0007] Further, the positioning member is a positioning pin, and the positioning pin corresponds to the position of the hole already opened on the rear mounting bracket, and the upper pin column is inserted into the hole.
[0008] Further, several support pins for supporting the rear mounting bracket are also fixed on the bottom plate, and the support pins correspond to the positions of the holes already opened on the rear mounting bracket.
[0009] Further, the first pressing plate assembly includes a first pressing plate pressing on the upper surface of the horizontal part of the rear mounting bracket. Two first bolts fixedly penetrating through both ends of the first pressing plate upward are provided on the bottom plate, and a first nut is screwed on the upper part of the first bolt.
[0010] Furthermore, a notch is opened at one end of the first pressing plate. When the first pressing plate rotates around the first bolt at one end, the first bolt at the other end can be inserted into the first pressing plate through the notch.
[0011] Further, the second pressing plate assembly includes a pressing plate positioning block fixed on the bottom plate, and a second pressing plate is connected above the pressing plate positioning block. The connecting part of the rear mounting bracket is fixedly clamped between the pressing plate positioning block and the second pressing plate.
[0012] Furthermore, the pressing plate positioning block is fixed on the bottom plate by a bolt-nut combination. Two second bolts fixedly penetrating through both ends of the second pressing plate upward are provided on the upper surface of the pressing plate positioning block, and a second nut is screwed on the upper part of the second bolt.
[0013] Furthermore, a notch is opened at one end of the second pressing plate. When the second pressing plate rotates around the second bolt at one end, the second bolt at the other end can be inserted into the second pressing plate through the notch.
[0014] Further, the side anti-deviation assembly includes a third bolt that penetrates through a bolt fixing block. A fixed third nut is provided on one side of the bolt fixing block, and the third bolt is screwed with the third nut. One end of the third bolt abuts against one side of the small end of the rear suspension bracket. The bolt fixing block is fixed on the bottom plate.
[0015] Further, a small end support member for supporting the small end is provided below the small end of the rear suspension bracket.
[0016] The positioning member on the tooling of the present utility model positions the rear suspension bracket, the support pin supports the rear suspension bracket, and the first pressing plate assembly and the second pressing plate assembly respectively press the horizontal part and the connecting part of the rear suspension bracket, jointly playing a role in fixing the main structure of the rear suspension bracket. The side anti-deviation assembly and the small end support member play a role in preventing the small end from shifting under the action of external forces during drilling. Under the combined action of each component, the rear suspension bracket is firmly clamped and accurately positioned, and the position of the rear suspension bracket is not easily shifted during the operation of drilling the small end hole, which facilitates the drilling operation and improves the drilling accuracy. The processing tooling for the rear suspension bracket of the present utility model has the characteristics of firm clamping, accurate positioning, convenient drilling, and high drilling accuracy.

A second nut 1201 is screwed on the upper part of the second bolt 12. By screwing the second nut 1201, the second pressing plate 11 is pressed against the connecting part 1303.
[0025] Refer to Figure 3 , two holes to be opened 1306 need to be opened on the small end 1304 of the rear suspension right bracket 13. The holes to be opened 1306 are drilled from the upper side of the small end 1304. On the lower side of the small end 1304, there is a side anti-deviation component 6. The side anti-deviation component 6 includes a third bolt 601 with one end abutted against the side of the small end 1304. The third bolt 601 passes through a bolt fixing block 603. A third nut 602 is welded on one side of the bolt fixing block 603. The third bolt 601 is screwed with the third nut 602. The bolt fixing block 603 is welded on a support seat 7. The support seat 7 is fixed on the bottom plate 1 with a bolt-nut combination. A fourth nut 801 is welded on the bottom plate 1. The fourth nut 801 can be arranged on the upper surface or the lower surface of the bottom plate 1. The fourth nut 801 is threadedly connected with a fourth bolt 8. The upper end of the fourth bolt 8 supports the small end 1304 from below.
[0026] Instructions for use: Fix the support pin 2, the first bolt 3, the positioning pin 5, the support base 7 (the bolt fixing block 603 has been welded to the support base 7, and the third nut 602 has been welded to the bolt fixing block 603), the fourth nut 801, and the fifth nut 901 on the bottom plate 1, and then fix the pressure plate positioning block 10 (the second bolt 12 has been welded to the pressure plate positioning block 10). Screw the third bolt 601 and the fourth bolt 8 onto the third nut 602 and the fourth nut 801 respectively. Fixing of the rear suspension right bracket 13: Insert the pre-opened hole 1305 corresponding to the positioning pin 5 on the rear suspension right bracket 13 into the upper pin column of the positioning pin 5 to position the rear suspension right bracket 13. Since the upper pin column of the positioning pin 5 is inserted into the pre-opened hole 1305, it also plays an auxiliary fixing role for the rear suspension right bracket 13. The support pin 2 supports the rear suspension right bracket 13 from below corresponding to the other pre-opened holes 1305, and the connecting part 1303 rests on the pressure plate positioning block 10. Insert the first pressure plate 4 into the first bolts 3 at both ends, and screw the first nut 301 onto the upper part of the first bolt 3.

Turn the second nut 1201 to clamp and fix the connecting part 1303 of the rear suspension right bracket 13. By pressing two different parts of the rear suspension right bracket 13, the purpose of firmly clamping the main body of the rear suspension right bracket 13 is achieved. Turn the third bolt 601 so that one end of the third bolt 601 abuts against the side of the small end 1304, and drill the to-be-opened hole 1306 from the opposite side. The third bolt 601 plays a role in preventing the small end 1304 from shifting due to the impact force during drilling, improving the drilling accuracy. Turn the fourth bolt 8 so that the upper end of the fourth bolt 8 abuts against the bottom of the small end 1304, which plays a role in supporting the small end 1304 from below and preventing the small end 1304 from shifting, improving the drilling accuracy. After the rear suspension right bracket 13 is clamped and fixed, use a drilling machine to open the to-be-opened hole 1306 on the small end 1304. After the drilling is completed, loosen the first nut 301 and the second nut 1201, rotate the first pressure plate 4 and the second pressure plate 11 so that the first bolt 3 and the second bolt 12 at the notch end are disengaged from the first pressure plate 4 and the second pressure plate 11, take out the rear suspension right bracket 13, and then place another rear suspension right bracket 13 to be drilled. Its positioning method is the same as the above operation. Rotate the first pressure plate 4 and the second pressure plate 11 so that the first bolt 3 and the second bolt 12 are inserted into the first pressure plate 4 and the second pressure plate 11 again. Screw the first nut 301 and the second nut 1201 to clamp and fix the rear suspension right bracket 13. Turn the third bolt 601 and the fourth bolt 8 as needed, and then start drilling. Repeat the above operation to drill the rear suspension right bracket 13.
