Abstract
Description
Technical Field
[0001] This utility model relates to the field of vibration damper technology, specifically to a three-point positioning pallet pressing fixture structure. Background Technology
[0002] Automotive shock absorbers have a crucial impact on vehicle handling stability and ride comfort, playing a vital role in the competitive automotive industry. During the production of automotive shock absorbers, the shock absorber and spring are integrated to support the weight of the vehicle body, chassis, cargo, and passengers, while simultaneously buffering and damping impact vibrations caused by vehicle speed and road surface excitation during driving. The spring tray, as a key load-bearing component of the automotive shock absorber, is critical to both ride comfort and driving safety.
[0003] When pressing a pallet, a pressing device is needed to press the spring pallet and the shock absorber cylinder to achieve an interference fit. Some existing pallet pressing devices achieve the interference fit by having an abutment block contact the surface of the pallet and then pressing the shock absorber cylinder into the center hole of the pallet. The abutment block is connected by a spring to provide floating support. However, due to the lack of spring limit, the stability during the pressing process is poor, and the pallet may tilt. This can lead to wear and damage between the pallet and the shock absorber cylinder during the pressing process, affecting the pressing effect of the pallet. Utility Model Content
[0004] In view of this, the present invention provides a three-point positioning pallet pressing fixture structure, which can ensure the stability of pallet pressing, avoid pallet displacement and damage, and improve the pressing effect between the pallet and the shock absorber cylinder.
[0005] To solve the above-mentioned technical problems, this utility model provides a three-point positioning pallet pressing fixture structure, including a base plate, on which a shock absorber cylinder is placed, and a floating plate for placing a pallet is provided above the bottom. The floating plate has mounting holes, and a number of floating components are provided between the base plate and the floating plate. The floating components can drive the floating plate to move down during pressing and reset after pressing.
[0006] The floating component includes a positioning cylinder 1 set on the base plate, a fixing column set inside the positioning cylinder 1, the fixing column being fixed to the base plate by a fixing pin at the bottom, a positioning cylinder 2 slidably set on the fixing column, the positioning cylinder 2 being fixed to the floating plate, the positioning cylinder 2 being able to drive the floating plate to slide on the fixing column, the fixing column being able to ensure the stability of the floating plate when sliding, the positioning cylinder 1 and the positioning cylinder 2 being connected by a spring, the spring being able to achieve the floating plate reset while ensuring the floating support of the floating plate.
[0007] There are 3 floating components, which are evenly distributed between the floating plate and the bottom plate to achieve the floating effect of the floating plate.
[0008] The floating plate is equipped with a lower mold for placing the pallet, ensuring that the pallet is vertically aligned with the shock absorber cylinder before pressing.
[0009] A pressing component is provided above the floating plate for pressing the pallet. The floating component moves downward by pressing down the pressing component, so that the pallet on the floating plate is pressed into the shock absorber cylinder by interference fit.
[0010] The bottom of the pressing component is equipped with an upper mold corresponding to the lower mold, which is used to limit and fix the pallet. When the pressing component drives the upper mold to move downward, the upper mold and the lower mold cooperate to clamp the pallet between them, ensuring that the pallet is fixed before pressing.
[0011] The base plate is equipped with positioning parts for positioning the shock absorber cylinder, and the operator can place the shock absorber cylinder into the positioning parts that are compatible with it.
[0012] The positioning component is fixed to the base plate by positioning pins. Different shock absorber cylinders can be adapted by disassembling and assembling the positioning component, which facilitates the positioning of the shock absorber cylinder to ensure the press-fitting operation.
[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:
[0014] 1. When using this utility model, it can ensure the stability of pallet pressing, avoid pallet displacement and damage, and improve the pressing effect between the pallet and the shock absorber cylinder.

Detailed Implementation
[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.
[0023] According to one embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 4 As shown: This embodiment provides a three-point positioning pallet pressing fixture structure, including a base plate 100, on which a shock absorber cylinder is placed. A floating plate 300 for placing a pallet is provided above the bottom. The floating plate 300 has mounting holes. Several floating components 200 are provided between the base plate 100 and the floating plate 300. The floating components 200 can drive the floating plate 300 to move down during pressing and reset after pressing. The floating components 200 can be electrically telescopic components.
[0024] Furthermore, the base plate 100 is provided with multiple floating components 200. Each floating component 200 includes a positioning cylinder 201 mounted on the base plate 100. A fixing post 202 is installed inside the positioning cylinder 201 and is fixed to the base plate 100 by a fixing pin at its bottom. A positioning cylinder 203 is slidably mounted on the fixing post 202 and is fixed to the floating plate 300. Both the positioning cylinder 201 and the positioning cylinder 203 have mounting holes. The mounting holes on the floating plate 300 can be U-shaped or V-shaped. The positioning cylinder 201 is fixed to the base plate 100 and the positioning cylinder 203 is fixed to the floating plate 300 through the mounting rod in the mounting hole. The positioning cylinder 203 can drive the floating plate 300 to slide on the fixed column 202. The fixed column 202 can ensure the stability of the floating plate 300 when sliding. The positioning cylinder 201 and the positioning cylinder 203 are connected by a spring 204. The spring 204 can realize the reset of the floating plate 300 and ensure the floating support of the floating plate 300.
[0025] Furthermore, there are three floating components 200, which are evenly distributed between the floating plate 300 and the base plate 100. This three-point positioning helps to ensure the floating support effect of the floating plate 300.
[0026] It is worth mentioning that the base plate 100 has through holes at all four corners, and the base plate 100 can be fixed to the pressing equipment by passing a fixing rod through the through holes.
[0027] According to another embodiment of the present invention, such as Figure 1 , Figure 2 and Figure 3 As shown, the floating plate 300 is provided with a lower mold 400 for placing the pallet, ensuring that the pallet and the shock absorber cylinder are vertically aligned before pressing, which facilitates pressing. Above the floating plate 300, there is a lower pressing member 501 for pressing the pallet. The lower pressing member 501 on the pressing equipment presses down to move the floating member 200 downward, thereby making the pallet on the floating plate 300 and the shock absorber cylinder press together with an interference fit. The bottom of the lower pressing member 501 is provided with an upper mold 502 corresponding to the lower mold 400, which is used to limit and fix the pallet. When the lower pressing member 501 drives the upper mold 502 to move downward, the upper mold 502 and the lower mold 400 clamp the pallet between them through the cooperation, ensuring that the pallet is fixed before pressing.
[0028] Furthermore, the base plate 100 is provided with a positioning component 600 for positioning the shock absorber cylinder. The operator can place the shock absorber cylinder into the positioning component 600 that is compatible with it. The positioning component 600 is fixed to the base plate 100 by positioning pins. Different shock absorber cylinders can be adapted by disassembling and assembling the positioning component 600, which facilitates the positioning of the shock absorber cylinder to ensure the press-fitting operation. The bottom of the positioning component 600 is provided with a positioning hole, and the positioning pin fixes the base plate 100 and the positioning component 600 together through the positioning hole.
[0029] The method of using this utility model is as follows: During the pallet pressing operation, the operator can disassemble and replace the positioning part 600 according to different types of shock absorber cylinders. Then, the shock absorber cylinder is placed in the appropriate positioning part 600. Afterwards, the operator can place the pallet inside the lower mold 400. During the pressing process, as the lower pressing part 501 moves downward, the upper mold 502 will first contact and engage with the lower mold 400 to fix the pallet. As the lower pressing part 501 continues to move downward, the positioning cylinder 203 will drive the floating plate 300 towards the fixed column 202. As the tray slides downwards, the spring 204 contracts under pressure until it gradually approaches the damper cylinder at the center hole of the tray. During the downward press, an interference fit is achieved to achieve the pressing effect. After the pressing operation is completed, the pressing part 501 retracts upwards, and the upper mold 502 separates from the lower mold 400. The floating part 200 will move the floating plate 300 upwards to reset due to the contraction and tension of the spring 204, and remove the pressed workpiece. This utility model can ensure the stability of the tray pressing, avoid the tray displacement and damage, and improve the pressing effect between the tray and the damper cylinder.
