Description

Technical Field

[0001] This utility model relates to the field of vehicle component assembly technology, and in particular to an auxiliary tooling for assembling a vehicle control arm buffer block. Background Technology

[0002] The control arm, also known as the cantilever, is a guiding and force-transmitting element of the car's suspension system. During vehicle operation, various forces acting on the wheels are transmitted to the vehicle body through the control arm. Because vehicles may encounter bumpy or complex road conditions during operation, the control arm will move relative to the vehicle body. Modern vehicles utilize buffer blocks on the control arm to cushion the impact when the control arm reaches its extreme position.

[0003] Chinese patent CN205237937U discloses an "Auxiliary Device for Assembling Vehicle Control Arm Buffer Blocks," which uses rubber pads to prevent nuts from falling off. However, this device is only applicable to rubber buffer blocks because rubber buffer blocks can deform for installation. Existing control arm buffer blocks mostly use metal gaskets, and the aforementioned device cannot position the metal gaskets, easily leading to metal gasket displacement or nuts falling into the control arm cavity. Therefore, an auxiliary tooling adapted for metal gasket installation is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary tooling for assembling a buffer block in a vehicle control arm, so as to solve the technical problem that metal gaskets in the vehicle control arm are prone to displacement or falling off during assembly in the prior art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an auxiliary tooling for assembling a vehicle control arm buffer block, including a cylindrical cover extending into the mounting hole of the control arm. The cover is used to assist in the installation of a nut that is bolted to the buffer block. One end of the cover extending into the mounting hole is provided with an annular bottom. A permanent magnet is provided on the inner end face of the annular bottom. The permanent magnet is used to attract the metal gasket to be installed.

[0006] Furthermore, the edge of the cover away from the annular bottom is provided with an outwardly protruding annular ridge, which is used to limit the depth of the cover extending into the control arm mounting hole.

[0007] Furthermore, the permanent magnet consists of multiple rectangular permanent magnets, which are radially distributed on the inner end face of the annular base, and the length of the rectangular permanent magnets is greater than the width of the annular base.

[0008] Furthermore, the side wall of the cover is provided with a plurality of elongated weight-reducing holes, which extend along the axial direction of the cover.

[0009] Furthermore, the metal gasket has a central mounting hole, the diameter of which is larger than the diameter of the buffer block bolt and smaller than the diameter of the nut.

[0010] Furthermore, a motor is provided at the top of the inner side of the cover. The motor is fixed to the upper end of the cover by a connecting rod. The output end of the motor is connected to a drive shaft, and a nut sleeve is provided at the end of the drive shaft.

[0011] Furthermore, the motor is equipped with a control button at its upper end, which is used to trigger the rotation of the nut sleeve.

[0012] Based on the above technical solution, the beneficial effects of this utility model are: 1. This utility model uses a permanent magnet set on the inner end face of the annular bottom to magnetically attract the metal gasket, thereby achieving precise positioning of the metal gasket during assembly and preventing the nut from falling into the control arm cavity during assembly, thus solving the technical problem of metal gasket displacement or detachment during installation.

[0013] 2. The annular convex ridge design of this utility model limits the depth of the cover extending into the mounting hole, avoiding interference installation problems caused by excessive insertion; the weight reduction hole reduces the overall weight of the tooling and improves the ease of operation.

[0014] 3. The optional motor drive mechanism of this utility model triggers the rotation of the nut sleeve through the control button to realize the automatic tightening of the nut, which can improve assembly efficiency and is especially suitable for batch operations on the production line.

[0020] The following combination Figure 1-4 This document provides a detailed description of the technical solutions provided in each embodiment of the present invention.

[0021] Example 1 like Figure 1-3 As shown, an auxiliary tooling for assembling a vehicle control arm buffer block includes a cylindrical cover 2 that extends into the control arm mounting hole. The outer diameter of the cover 2 is slightly smaller than the diameter of the control arm mounting hole. One end of the cover 2 extending into the mounting hole has an annular base 3. Multiple rectangular permanent magnets 4 are radially embedded on the inner end face of the annular base 3, with the length of each permanent magnet 4 greater than the width of the annular base 3. An annular protrusion 1 is provided on the outer edge of the end of the cover 2 away from the annular base 3 to limit the insertion depth of the cover 2. During assembly, a metal washer 5 is attracted to the outer end face of the annular base 3 via the permanent magnets 4. Then, the cover 2 is inserted into the control arm mounting hole until the annular protrusion 1 abuts against the edge of the mounting hole. At this point, the buffer block bolt 7 passes through the mounting hole of the metal washer 5, and then the nut 6 is manually tightened. Because the diameter of the mounting hole of the metal washer 5 is between the diameter of the buffer block bolt 7 and the diameter of the nut 6, the nut 6 is effectively constrained on the surface of the metal washer 5, avoiding the risk of displacement or detachment. Multiple elongated weight-reducing holes 8 are provided on the side wall of the cover body 2, extending axially to reduce the weight of the tooling. After installation, the tooling is lifted to complete the assembly work.

[0022] Example 2 An auxiliary tooling for assembling a vehicle control arm buffer block is basically the same as that in Embodiment 1; furthermore, the permanent magnet 4 on the inner end face of the annular bottom 3 is an annular permanent magnet 4, and its inner diameter is larger than that of the annular bottom 3, so as to enhance the attraction force on the edge of the metal pad 5.

[0023] Example 3 like Figure 1-4 As shown, an auxiliary tooling for assembling a vehicle control arm buffer block, based on embodiment 1 or 2, has a motor 10 fixed to the top of the inner side of the cover 2. The output end of the motor 10 is connected to a drive shaft 12, and a detachable nut sleeve 13 is fitted to the end of the drive shaft 12 to accommodate nuts 6 of different sizes. A control button 9 is provided on the upper surface of the motor 10. During assembly, the nut 6 is pre-placed in the nut sleeve 13, and the metal washer 5 is attracted to the outer end face of the annular bottom 3 by a permanent magnet 4. Then, the cover 2 is inserted into the control arm mounting hole. Pressing the control button 9 starts the motor 10, and the nut sleeve 13 automatically tightens the nut 6. Then, the tooling is lifted to complete the assembly work.

[0024] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
