Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology for hydraulic equipment, specifically to a vibration reduction support structure for a servo press hydraulic pump station. Background Technology

[0002] With the rapid development of industrial automation and precision manufacturing technologies, servo presses have been widely used in automobile manufacturing, electronic assembly, aerospace, and other fields due to their advantages such as high precision, high efficiency, and low energy consumption. The core power source of a servo press—the hydraulic pump station—typically consists of a servo motor, oil pump, oil tank, integrated valve group, and electrical control system. Mechanical motion is achieved through the pressure transmission of hydraulic oil. However, during operation, the servo press hydraulic pump station generates significant vibration and noise due to the high-speed rotation of the servo motor, the periodic suction and discharge of the oil pump, and the frequent operation of the hydraulic valves. This vibration not only affects the processing accuracy and stability of the equipment but may also accelerate the wear of mechanical parts, shortening the equipment's service life. Meanwhile, the noise can adversely affect the physical and mental health of operators and reduce the quality of the working environment.

[0003] Currently, the common solution for vibration reduction in hydraulic pump stations of servo presses is to install vibration dampers (such as rubber damping pads, spring dampers, etc.) between the pump station and the support base to absorb and isolate vibration energy. However, existing vibration damping support structures have the following shortcomings in practical applications:

[0004] The connection between the shock absorber and the support base and pump station is usually a bolted rigid connection. When a single shock absorber needs to be repaired or replaced, the entire shock absorber device must be disassembled, which is cumbersome and time-consuming, increasing maintenance costs and downtime. At the same time, the existing shock absorber support structure is mostly a customized design, which is difficult to adjust flexibly according to the load characteristics, vibration frequency and other parameters of different pump stations, resulting in poor versatility. Utility Model Content

[0005] The purpose of this invention is to provide a vibration damping support structure for a servo press hydraulic pump station, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing support structure for a servo press hydraulic pump station, comprising a hydraulic station and a base, wherein a plurality of support frames are provided between the hydraulic station and the base, each of the plurality of support frames being hexagonal in shape, each of the plurality of support frames having an open upper end, each of the plurality of support frames having a top cover at its upper end, each of the plurality of top covers being fixedly connected to the support frames by bolts, and each of the plurality of top covers being fixedly connected to the bottom end of the hydraulic station; each of the plurality of support frames having a mounting seat fixedly connected to its bottom wall, each of the plurality of mounting seats having a mounting groove at its upper end, each of the plurality of top covers having a shock absorber between its bottom end and the mounting seat, each of the plurality of shock absorbers having a chassis fixedly connected to its bottom end, each of the plurality of chassis being movably inserted into a corresponding mounting groove, and each of the plurality of mounting seats having a limiting component at its upper end;

[0007] Each of the limiting components includes a fixed shaft, which is vertically fixed to the upper end of the mounting base. A sleeve block is fixedly sleeved on the upper end of the fixed shaft. Two limiting blocks are rotatably connected to the outside of the fixed shaft. Torsion springs are fixedly connected between the sleeve block, the mounting base, and the corresponding limiting blocks. The two torsion springs are sleeved around the fixed shaft. The two limiting blocks are located on both sides of the bottom end of the shock absorber.

[0008] Preferably, the bottom ends of the bolts are threaded to the corresponding support frame, and the bolts are movably sleeved with the corresponding top cover.

[0009] Preferably, a buffer pad is fixedly connected between the bottom end of each of the top covers and the corresponding support frame.

[0010] Preferably, each of the shock absorbers has a top plate fixedly connected to its top, each of the top plates has a guide block fixedly connected to its upper end, and each of the top covers has a guide groove at its bottom end that matches the guide block. The guide blocks are respectively movably inserted into the guide grooves.

[0011] Preferably, all of the limiting blocks are arc-shaped, and the inner wall of the end of the limiting block away from the fixed axis is in contact with the outer wall of the bottom end of the shock absorber.

[0012] Compared with existing technologies, the shock absorber achieves rapid fixation through the plug-in structure of the chassis and mounting base, in conjunction with the limiting components. The shock absorber can be replaced individually without disassembling the entire support structure, which greatly shortens maintenance time. At the same time, the hexagonal structure of the support frame and the independent installation method of the shock absorber make it easy to adjust the number and layout of the shock absorbers according to parameters such as pump station load and vibration frequency, so as to adapt to different working conditions.

[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] Please see Figure 1-5 The present invention provides the following technical solution:

[0021] Example 1: A vibration damping support structure for a servo press hydraulic pump station includes a hydraulic station 1 and a base 2. Several support frames 3 are provided between the hydraulic station 1 and the base 2. Each support frame 3 is hexagonal in shape, with an open top. Each support frame 3 has a top cover 4 at its upper end, which is fixedly connected to the support frame 3 by bolts 5. The top covers 4 are also fixedly connected to the bottom of the hydraulic station 1. Mounting seats 9 are fixedly connected to the bottom walls of each support frame 3, with mounting grooves 10 at their upper ends. The bottom ends of the top covers 4... Shock absorbers 6 are provided between the support frame 3 and the mounting base 9. Several shock absorbers 6 are fixedly connected to the bottom of the base 8. Several base 8 are movably inserted into the corresponding mounting slots 10. The shock absorbers 6 are quickly fixed through the insertion structure between the base 8 and the mounting base 9, in conjunction with the limiting component 7. The shock absorbers 6 can be replaced individually without disassembling the entire support structure, which greatly shortens the maintenance time. At the same time, the hexagonal structure of the support frame 3 and the independent installation method of the shock absorbers 6 make it easy to adjust the number and layout of the shock absorbers 6 according to parameters such as pump station load and vibration frequency to adapt to different working conditions.

[0022] The bottom ends of several bolts 5 are threaded to the corresponding support frame 3, and several bolts 5 are movably sleeved with the corresponding top cover 4, so as to ensure that the bolts 5 can move up and down slightly, thereby ensuring the shock absorption effect of the shock absorber 6.

[0023] Several top covers 4 are fixedly connected to the bottom of the corresponding support frame 3 with buffer pads 11 to further absorb high-frequency vibration and enhance the shock absorption effect;

[0024] A top plate 13 is fixedly connected to the top of several shock absorbers 6, and a guide block 14 is fixedly connected to the upper end of several top plates 13. A guide groove 12 matching the guide block 14 is provided at the bottom of several top covers 4. Several guide blocks 14 are movably inserted into several guide grooves 12. By inserting the guide blocks 14 into the guide grooves 12, the shock absorber 6 can be quickly positioned, which facilitates the installation of the shock absorber 6.

[0025] In use, the shock absorber 6 is placed inside the support frame 3, with the base plate 8 at the bottom of the shock absorber 6 inserted into the mounting groove 10 on the mounting base 9, and the guide block 14 at the top of the top plate 13 inserted into the guide groove 12, thus completing the installation of the shock absorber 6. The shock absorber 6 can be replaced separately without disassembling the entire support structure, greatly shortening maintenance time. The shock absorber 6 plays a role in damping the hydraulic station 1. Furthermore, the combined design of the hexagonal support frame 3, the top cover 4, and the buffer pad 11 can effectively disperse the vibration energy in the vertical and horizontal directions, reducing the risk of resonance. The number and layout of the shock absorbers 6 can also be adjusted according to parameters such as pump station load and vibration frequency to adapt to different working conditions.

[0026] In Example 2, based on Example 1, a limiting component 7 is further added to enhance the installation stability and maintainability of the shock absorber 6. Each limiting component 7 includes a fixed shaft 72, which is vertically fixed to the upper end of the mounting base 9. A sleeve block 73 is fixedly sleeved on the upper end of the fixed shaft 72. Two limiting blocks 71 are rotatably connected to the outside of the fixed shaft 72. Torsion springs 74 are fixedly connected between the sleeve block 73, the mounting base 9, and the corresponding limiting block 71. Both torsion springs 74 are sleeved around the fixed shaft. The limit blocks 71 are located on both sides of the bottom end of the shock absorber 6. Each limit block 71 is arc-shaped. The inner wall of the end of the limit block 71 away from the fixed shaft is in contact with the outer wall of the bottom end of the shock absorber 6. The shock absorber 6 is limited by the two limit blocks 71, thereby ensuring the installation stability of the shock absorber 6. When it is necessary to disassemble the shock absorber 6, the limit block 71 can be manually rotated to open outward around the fixed shaft 72, thereby releasing the shock absorber 6 without disassembling the entire support structure, which greatly shortens the maintenance time and reduces the maintenance cost.
