Description

Technical Field

[0001] This utility model relates to a positioning tool, specifically a special positioning tool used when assembling the lower connecting plate and the front shock absorber of a motorcycle. Background Technology

[0002] Currently, when assembling the motorcycle lower clamp plate and front shock absorber, the workpiece is placed horizontally on the workbench. Because the support points of the two front shock absorbers are not coplanar, and the lower end of the front shock absorber is suspended and drooping without any support points, and the relative positional deviation between the support points of the lower clamp plate and the front shock absorber is large, the positioning before assembly is inaccurate. This results in a large height difference between the two front shock absorbers after assembly with the lower clamp plate, leading to a high defect rate. Special personnel are required to make adjustments to ensure that the two front shock absorbers are at the same height. However, this assembly method is not only inefficient but also wastes manpower. Utility Model Content

[0004] To achieve the above objectives, the technical solution of this utility model is: a special positioning fixture for assembling the lower connecting plate and the front shock absorber, the innovation of which lies in: including a positioning platform, and a front shock absorber positioning unit and a lower connecting plate positioning unit disposed on the positioning platform.

[0005] The front shock absorber positioning unit includes positioning blocks, and positioning blocks are respectively provided at both ends of the positioning platform along its length.

[0006] The lower connecting plate positioning unit includes a cylinder, a crank arm, a pressure block, and a positioning sleeve. Both the cylinder and the positioning sleeve are mounted on a positioning platform. The pressure block is connected to the cylinder's push rod via the crank arm, and the crank arm is rotatably connected to the cylinder's outer shell.

[0007] The front shock absorber is positioned vertically and inverted on the positioning platform by the positioning block. The lower connecting plate is fitted onto the front shock absorber and connected with the positioning sleeve. At this time, the drive cylinder is activated, which drives the crank arm to rotate, so that the pressure block abuts against the lower connecting plate, completing the positioning of the lower connecting plate and the front shock absorber before assembly.

[0008] In the above technical solution, the positioning block has a positioning hole that mates with the shaft hole of the front shock absorber.

[0009] In the above technical solution, the positioning platform is provided with a positioning base, the positioning sleeve is provided on the front side of the positioning base, and the cylinder is provided on the back side of the positioning base.

[0010] In the above technical solution, the positioning sleeve is connected to the positioning base through a connecting plate.

[0011] In the above technical solution, a support beam is provided on the back of the positioning base, and the cylinder is fixed on the support beam.

[0012] In the above technical solution, the positioning base has an L-shaped structure, and the bottom of the positioning base forms a positioning and pressing connection with the positioning platform through a U-shaped pressing block.

[0013] In the above technical solution, the cylinder housing is provided with a connecting block, and the two sides of the crank arm are rotatably connected to the connecting block through a linkage plate, so that the crank arm drives the pressure block to rotate under the action of the cylinder.

[0014] In the above technical solution, the connecting block has a T-shaped structure.

[0015] In the above technical solution, the pressure block includes a pressure plate and an elastic pressure head. The pressure plate is detachably connected to the crank arm, and the elastic pressure head is fitted onto the end of the pressure plate.

[0016] The positive effects of this utility model are: after adopting the special positioning fixture used when assembling the lower connecting plate and the front shock absorber using the lower connecting plate of this utility model, since it includes a positioning platform, as well as a front shock absorber positioning unit and a lower connecting plate positioning unit set on the positioning platform,

[0017] The front shock absorber positioning unit includes positioning blocks, and positioning blocks are respectively provided at both ends of the positioning platform along its length.

[0018] The lower connecting plate positioning unit includes a cylinder, a crank arm, a pressure block, and a positioning sleeve. Both the cylinder and the positioning sleeve are mounted on a positioning platform. The pressure block is connected to the cylinder's push rod via the crank arm, and the crank arm is rotatably connected to the cylinder's outer shell.

[0019] The front shock absorber is vertically and invertedly positioned on the positioning platform via a positioning block. The lower connecting plate is fitted onto the front shock absorber and connected with the positioning sleeve. At this time, the drive cylinder is activated, causing the crank arm to rotate, so that the pressure block abuts against the lower connecting plate, completing the positioning of the lower connecting plate and the front shock absorber before assembly.

[0020] Therefore, this utility model fixes the positioning units of the lower connecting plate and the front shock absorber on the same platform, making it easy to ensure the relative accuracy of the two positioning units. Furthermore, the lower connecting plate and the front shock absorber are assembled in a vertical, inverted manner, with the lower connecting plate as the main positioning point and the two front shock absorbers providing auxiliary positioning. This positioning method, using this utility model before assembly, not only ensures high positioning accuracy but also significantly reduces the height error between the two front shock absorbers after assembly. Specifically, the lower connecting plate is pre-fitted onto the front shock absorber positioned on the positioning block, and the lower connecting plate is positioned and engaged with the positioning sleeve. Then, the cylinder is driven to rotate and press the pressure block onto the lower connecting plate. When the lower connecting plate and the front shock absorber are tightened with connecting bolts, the pressure block presses down on the lower connecting plate, effectively preventing movement during tightening. Using this utility model for positioning and assembling the lower connecting plate and the front shock absorber significantly reduces the defect rate.

[0021] This utility model is not only simple and reliable in structure, but also convenient to use and easy to promote. It has multiple positioning support points, which improves positioning accuracy and greatly reduces the height error between the two shock absorbers after assembly. This reduces quality problems caused by poor product assembly, reduces the number of adjustment personnel, saves production costs, and improves assembly efficiency. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and the given embodiments, but it is not limited thereto.

[0028] like Figure 1 , 2 As shown in Figures 3, 4, and 5, a special positioning fixture for assembling a lower connecting plate with a front shock absorber includes a positioning platform 1, and a front shock absorber positioning unit and a lower connecting plate positioning unit mounted on the positioning platform 1.

[0029] The front shock absorber positioning unit includes positioning blocks 2, and positioning blocks 2 are respectively provided at both ends of the positioning platform 1 along its length.

[0030] The lower connecting plate positioning unit includes a cylinder 3, a crank arm 4, a pressure block 5, and a positioning sleeve 6. The cylinder 3 and the positioning sleeve 6 are both mounted on the positioning platform 1. The pressure block 5 is connected to the push rod of the cylinder 3 via the crank arm 4, and the crank arm 4 is rotatably connected to the outer shell of the cylinder 3.

[0031] The front shock absorber is positioned vertically and invertedly on the positioning platform 1 by the positioning block 2. The lower connecting plate is fitted onto the front shock absorber and is positioned and connected with the positioning sleeve 6. At this time, the drive cylinder 3 is activated, which drives the crank arm 4 to rotate, so that the pressure block 5 abuts against the lower connecting plate, completing the positioning of the lower connecting plate and the front shock absorber before assembly.

[0032] Furthermore, in order to facilitate the operation of the cylinder, the positioning platform 1 is equipped with a switch 11 for controlling the opening, closing and stopping of the cylinder 3.

[0033] Furthermore, such as Figure 3 As shown, to ensure high-precision positioning of the front shock absorber, the positioning block 2 has a positioning hole 21 that mates with the shaft hole of the front shock absorber. In use, the front shock absorber is upright with its end inverted within the positioning hole.

[0034] Furthermore, such as Figure 1 , 2 As shown, in order to facilitate the assembly of the positioning sleeve and the cylinder, the positioning platform 1 is provided with a positioning base 7, the positioning sleeve 6 is located on the front side of the positioning base 7, and the cylinder 3 is located on the back side of the positioning base 7.

[0035] Furthermore, such as Figure 2 As shown, in order to facilitate fixing the positioning sleeve, the positioning sleeve 6 is connected to the positioning base 7 through the connecting plate 8.

[0036] Furthermore, such as Figure 2 As shown, in order to make the structure more reasonable, a support beam 12 is provided on the back of the positioning base 7, and the cylinder 4 is fixed on the support beam 12.

[0037] Furthermore, in order to further improve the structural rationality and compactness, and to ensure the stability of the connection between the positioning base and the positioning platform, the positioning base 7 is an L-shaped structure, and the bottom of the positioning base 7 forms a positioning press with the positioning platform 1 through a U-shaped pressing block.

[0038] Furthermore, such as Figure 2As shown, in order to ensure that the pressure block can flip and press the lower connecting plate under the action of the crank arm, the outer shell of the cylinder 3 is provided with a connecting block 9. The two sides of the crank arm 4 are rotatably connected to the connecting block 9 through the linkage plate 10, so that the crank arm 4 drives the pressure block 5 to rotate under the action of the cylinder 3.

[0039] Furthermore, in order to ensure the balance and reliability of the curved arm during movement, as well as the stable rotation of the curved arm relative to the connecting block, the connecting block 9 has a T-shaped structure.

[0040] Furthermore, such as Figure 2 As shown, in order to prevent the lower connecting plate from shifting during the process of fastening the lower connecting plate to the front shock absorber by connecting bolts, and to prevent the pressure block from damaging the lower connecting plate during pressing, the pressure block 5 includes a pressure plate 51 and an elastic pressure head 52. The pressure plate 51 is detachably connected to the crank arm 4, and the elastic pressure head 52 is fitted onto the end of the pressure plate 51.

[0041] like Figure 4 , 5 As shown, the positioning units used for positioning the lower plate and the front shock absorber are fixed on the same platform. The relative accuracy of the two positioning units is easy to ensure. Furthermore, the lower plate and the front shock absorber are assembled in a vertical and inverted manner, with the lower plate as the main positioning point and the two front shock absorbers as auxiliary positioning points. This ensures that the positioning accuracy of the lower plate and the front shock absorber is high before assembly, and also greatly reduces the height error of the two front shock absorbers after assembly.

[0042] The specific usage process is as follows: the lower connecting plate 14 is pre-installed on the front shock absorber 13 set on the positioning block 2, and the lower connecting plate 14 is positioned and engaged with the positioning sleeve 6. Then, the cylinder 3 is driven to operate, and the elastic pressure head 52 of the pressure block 5 rotates and presses against the lower connecting plate 14. When the lower connecting plate 14 and the front shock absorber 13 are fastened with connecting bolts, the elastic pressure head 52 of the pressure block 5 presses down on the lower connecting plate 14, which can effectively prevent movement during the fastening process. Using this utility model for assembly significantly reduces the defect rate.

[0043] This utility model is not only simple and reliable in structure, but also convenient to use and easy to promote. It has multiple positioning support points, which improves positioning accuracy and greatly reduces the height error between the two shock absorbers after assembly. This reduces quality problems caused by poor product assembly, reduces the number of adjustment personnel, saves production costs, and improves assembly efficiency.

[0044] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
