Description

Technical Field

[0001] This utility model relates to the field of automotive subframe assembly, specifically to a subframe bushing press-fitting multi-model quick-switching positioning mechanism. Background Technology

[0002] The subframe is an important component of a car chassis, significantly impacting vehicle comfort and handling. Connected to the body via bushings, the subframe effectively reduces vibration and suppresses abnormal noises, improving driving comfort while balancing handling performance.

[0003] The bushing is pressed directly into the bushing tube on the subframe using equipment. During the pressing process, in order to ensure the smooth pressing of the bushing, it is necessary to position the bushing and the bushing tube on the subframe. The size and shape of the bushings on different subframes and the bushings at different positions on the same subframe are different, so the bushing tube positioning mechanism and the bushing positioning mechanism are different.

[0004] Previous pressing equipment was mostly designed as specialized equipment, or the bushing positioning mechanism used traditional multiple bolts and positioning pins for fixed connection. This resulted in low equipment utilization, the inability of a single operator to complete the replacement, and cumbersome disassembly and assembly, leading to low efficiency. Therefore, there is an urgent need to develop a multi-vehicle model quick-change positioning mechanism for subframe bushing pressing to meet manufacturing requirements. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-vehicle model quick-switching positioning mechanism for subframe bushing press-fitting, so as to solve the switching requirements of the positioning mechanism in the existing bushing press-fitting process. The specific technical solution is as follows:

[0006] A subframe bushing press-fitting multi-model quick-change positioning mechanism includes a bushing positioning mechanism and a bushing tube positioning mechanism. The bushing positioning mechanism includes a positioning support mounting base, a bushing positioning support, a clamping plate, a fixing bolt, and a fixing nut. The bushing tube positioning mechanism includes a bushing tube positioning support mounting base, a bushing tube positioning support, a positioning mandrel, and a limiting bolt. The bushing is placed on the bushing positioning support, which is connected to the positioning support mounting base via the fixing nut, fixing bolt, and clamping plate. The bushing tube positioning support is connected to the bushing tube positioning support mounting base via the positioning mandrel and the limiting bolt.

[0007] Furthermore, the bushing positioning support and the bushing tube positioning support are provided correspondingly and have different sizes and specifications.

[0008] Furthermore, the bushing positioning support mounting base is provided with a clearance groove that matches the size of the positioning mandrel, and the positioning mandrel moves within the clearance groove.

[0009] Furthermore, bolt holes are provided on the side of the clearance groove to match the limiting bolts.

[0010] Furthermore, the fixing nut is disposed inside the positioning support mounting base, and the bushing positioning support is provided with a fixing bolt through hole, through which the fixing bolt passes and matches the fixing nut.

[0011] The method for switching the bushing positioning mechanism is as follows: loosen the fixing bolts, loosen the clamping plate, and open the fixing bolts and clamping plate outwards to remove the bushing positioning support from the positioning support mounting base; take another bushing positioning support and place it in the corresponding position on the positioning support mounting base, put the fixing bolts and clamping plate inwards, and tighten the bolts to complete the switching.

[0012] The method for switching the bushing positioning mechanism is as follows: Loosen the limiting bolts, rotate the bushing positioning seat so that the positioning mandrel is in the clearance groove position of the bushing positioning support mounting seat, and then remove the bushing positioning seat; take another bushing positioning seat, align the positioning mandrel with the clearance groove position of the bushing positioning support mounting seat and install it upwards, rotate it after it is in place, and then tighten the limiting bolts to complete the switching.

[0013] The structure of this utility model enables the installation of different bushing positioning mechanisms on the bushing pressing equipment, and the bushing tube positioning mechanism can be quickly switched to complete the pressing of bushings of different specifications and models, thus meeting the final product manufacturing requirements.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] like Figure 1-3 As shown, a subframe bushing press-fitting multi-model quick-change positioning mechanism includes a bushing positioning mechanism and a bushing tube positioning mechanism. The bushing positioning mechanism includes a positioning support mounting base 1, a bushing positioning support 2, a bushing 3, a fixing nut 6, a fixing bolt 7, and a clamping plate 8. The bushing tube positioning mechanism includes a bushing tube positioning support 4, a bushing tube positioning support mounting base 5, a limiting bolt 9, and a positioning mandrel 10. The bushing 3 is placed on the bushing positioning support 2, and the bushing positioning support 2 is connected to the positioning support mounting base 1 through the fixing nut 6, the fixing bolt 7, and the clamping plate 8. The bushing tube positioning support 4 is connected to the bushing tube positioning support mounting base 5 through the positioning mandrel 10 and the limiting bolt 9.

[0021] The working principle of this utility model is briefly described as follows:

[0022] Loosen the fixing bolt 7 from the fixing nut 6 and loosen the clamping plate 8. At this time, open the fixing bolt and clamping plate outward as a whole, and the bushing positioning support 2 can be directly removed from the positioning support mounting base 1. Take another type of bushing positioning support 2, place it in the corresponding position of the positioning support mounting base 1, put the fixing bolt 7 and clamping plate 8 inward into place, and tighten the fixing bolt 7 on the fixing nut 6 to complete the switching.

[0023] Loosen the limiting bolt 8, rotate the bushing positioning seat 3 so that the positioning core 10 is in the clearance groove position of the bushing positioning support mounting seat 5, and then remove the bushing positioning seat 3; take another bushing positioning seat 3, align the positioning core shaft 10 with the clearance groove position of the bushing positioning support mounting seat 5 and install it upwards, rotate it after it is in place, and then tighten the limiting bolt 8 to complete the switching.
