[0028] The present invention will now be further described with reference to the accompanying drawings.

[0029] This utility model provides the following technical solution:

[0030] As attached Figure 1-5 As shown, this utility model discloses a shock-absorbing pad press fixture, including a pressurizing device 1, a power device, and a base plate 2. One side of the pressurizing device 1 is connected to the power device, and the other side is connected to the base plate 2. A base 3 is provided on the base plate 2, and a product 4 to be processed is provided on the base 3. The pressurizing device 1 includes a top plate 5, a middle plate 6, and a connecting member 7. The connecting member 7 connects the base plate 2, the middle plate 6, and the top plate 5. The top plate 5 and the middle plate 6 are movably mounted on the connecting member 7. A pressure column 8 is provided on the side of the top plate 5 near the base 3. A pressure hole 9 corresponding to the position of the pressure column 8 is opened on the middle plate 6. A pressure sleeve 10 is provided in the pressure hole 9. The pressure sleeve 10 has a hollow structure. The power device can drive the top plate 5 and the middle plate 6 to move up and down reciprocally. The middle plate 6 drives the pressure sleeve 10 to press and fix the product 4 to be processed. The top plate 5 drives the pressure column 8 to pass through the pressure sleeve 10 to process the product 4 to be processed. In this embodiment, the pressure sleeve 10 has an inverted trapezoidal cross-section, and a screw hole is provided at the upper end of the pressure sleeve 10. A corresponding screw hole is also provided on the middle plate 6. The two are fixedly connected by screws 29. The function of the pressure device 1 is to stably press and process the product 4 to be processed. Under the drive of the power device, the top plate 5 and the middle plate 6 can move up and down. At the same time, the design of the inverted trapezoidal pressure sleeve 10 makes the processing position more precise, the processing depth and width more accurately controlled, and improves the pressing effect, avoiding slippage or displacement during processing. In addition, the fixed connection between the pressure sleeve 10 and the middle plate 6 by screws 29 further improves the stability and reliability of the pressure device 1. In this embodiment, four pressure columns 8 are provided. In other embodiments, the pressure columns 8 can also be one, two, eight, etc., and the number is not limited.

[0031] Furthermore, the connecting member 7 includes a guide rod 11, a compression spring 12, and a column 13. One end of the guide rod 11 is connected to the top plate 5, and the other end is connected to the middle plate 6. The top plate 5 and the middle plate 6 can move along the axial direction of the guide rod 11. The bottom plate 2, the middle plate 6, and the top plate 5 are connected by the column 13. One end of the column 13 is connected to the bottom plate 2, and the other end passes through the middle plate 6 and connects to the top plate 5. The middle plate 6 and the top plate 5 move along the axial direction of the column 13. The compression spring 12 is located on the outer side of the column 13. In this embodiment, the top plate 5 and the middle plate 6 can move up and down along the axial direction of the guide rod 11. The compression spring 12 provides a buffering effect during the movement of the top plate 5 and the middle plate 6, thereby avoiding excessive impact on the product 4 to be processed, and making the reset process easier, ensuring the stability and quality of the processing. Furthermore, the design of the guide rod 11 ensures precise and stable positioning of the top plate 5 during descent and return, preventing swaying or tilting and thus guaranteeing machining accuracy and product quality. The column 13 not only connects the top plate 5, middle plate 6, and bottom plate 2 but also distributes pressure to a certain extent, making the entire fixture more stable and durable.

[0032] Furthermore, the base 3 has an upward-facing elastic groove 14. An elastic element 15 is disposed within the elastic groove 14. The elastic element 15 includes a limiting spring 16 and an elastic block 17. One end of the limiting spring 16 is connected to the bottom wall of the elastic groove 14, and the other end is connected to the elastic block 17. The elastic block 17 has a convex cross-section and includes a limiting end 18 and a fixed end 19. An annular limiting end 20 protrudes from the inner wall of the elastic groove 14 near the groove opening, and the annular limiting end 20 limits the movement of the elastic block 17. In this embodiment, the annular limiting end 20 and the fixed end 19 of the elastic block 17 abut against each other for movement limitation, while the limiting end 18 of the elastic block 17 can extend out of the groove opening of the elastic groove 14 and rebound after the product 4 to be processed is completed, thus serving as a demolding function. The elastic block 17 has a convex cross-section, and the annular limiting end 20 limits its movement, preventing it from disengaging from the elastic groove 14 and improving the stability and reliability of the fixture. The design of the elastic block 17 allows it to undergo elastic deformation under pressure, absorbing some impact force and protecting the product 4 from damage or deformation caused by excessive impact. The elastic block 17 provides better fixation for the product 4 during processing, preventing shaking or displacement and ensuring processing accuracy and product quality. The annular limiting end 20 further enhances the stability and reliability of the elastic block 17, enabling it to better fulfill its fixing and limiting functions. Furthermore, the limiting spring 16 allows the elastic block 17 to move under external force and return to its original position after the force is removed, achieving automatic ejection of the product 4 and improving work efficiency and convenience. In this embodiment, four elastic grooves 14 are provided. In other embodiments, the number of elastic grooves 14 can also be adjusted according to actual needs to adapt to products 4 to be processed with different specifications and sizes.

[0033] Furthermore, a fixing groove 21 is provided at the center of the base 3, and a fixing device 22 is provided within the fixing groove 21. The fixing device 22 includes a power source and several fixing heads 23. The fixing heads 23 are arranged in a ring structure, and the fixing heads 23 clamp the product 4 to be processed under the drive of the power source. The function of the fixing heads 23 is to fix the product 4 to be processed to ensure that there is no shaking or displacement during processing. In this embodiment, the fixing heads 23 are arranged in a ring structure, which is a fixing method based on the shape of the product 4 to be processed. The product 4 to be processed has a hollow circle in the middle, and the fixing heads 23 are arranged in a ring structure inside the hollow circle to fix the middle part of the product 4 to be processed. With the help of the pressure sleeve 10, the product 4 to be processed can be better fixed from all directions. During processing, the fixing head 23 adaptively adjusts according to the size of the product 4 to be processed. Driven by a power source, the fixing head 23 moves to closely fit the surface of the product 4, ensuring processing stability and accuracy. The power source is a device capable of providing power, such as a cylinder or hydraulic system. In this embodiment, the fixing head 23 moves towards and away from its center position. Furthermore, the design of the fixing head 23 allows it to apply uniform pressure when fixing the product 4, avoiding processing errors or product quality problems caused by uneven pressure, shaking, or displacement. (Power source diagram not shown)

[0034] Furthermore, a positioning block 24 is provided on the top plate 5. One side of the positioning block 24 is connected to the top plate 5, and the other side is connected to the power device. The power device drives the top plate 5 to move vertically through the positioning block 24. In this embodiment, the function of the positioning block 24 is to make a precise connection with the power device, so that the power device can stably drive the top plate 5 to move vertically. The design of the positioning block 24 takes into account the output characteristics of the power device and the movement requirements of the top plate 5, ensuring the firmness of the connection and the smoothness of the movement. During the processing, the power device transmits power to the top plate 5 through the positioning block 24, and the top plate 5 then drives the middle plate 6 and the pressure column 8 to press and process the product 4 to be processed. The precise connection of the positioning block 24 makes the entire pressurizing device 1 more stable during movement, avoiding shaking or tilting, thereby ensuring processing accuracy and product quality.

[0035] Furthermore, the base plate 2 has a first fixing hole 25 and a first positioning hole 26, and the base 3 has a corresponding second fixing hole 27 and a second positioning hole 28. The base plate 2 also has a screw 29 and a cylindrical pin 30. One end of the screw 29 passes through the second fixing hole 27 and extends into the first fixing hole 25 to connect the base plate 2 and the base 3. One end of the cylindrical pin 30 passes through the second positioning hole 28 and extends into the first positioning hole 26 to position the base plate 2 and the base 3. The first positioning hole 26, in conjunction with the second positioning hole 28, makes the positioning between the base 3 and the base plate 2 more accurate, avoiding deviations or shaking during processing. Simultaneously, the connection method of the first fixing hole 25, the second fixing hole 27, and the screw 29 further enhances the connection strength between the base 3 and the base plate 2, making the entire fixture more stable and durable. During processing, this stable connection method can effectively resist various external forces, ensuring the stability and accuracy of the processing. Furthermore, the cylindrical pin 30 also serves as a guide, allowing the base 3 to be more easily and accurately aligned with the positioning holes on the base plate 2 during installation, thereby improving installation efficiency and accuracy. In summary, this meticulous design makes the entire shock-absorbing pad press-fit fixture more stable and reliable during use, ensuring processing accuracy and product quality. In this embodiment, the positioning holes and fixing holes are set in two sets; in other embodiments, four or eight sets can be designed depending on the size and weight of the processed product. Besides ensuring stable and efficient installation, the design of the fixing holes and positioning holes also makes the fixture easy and quick to disassemble.

[0036] Furthermore, the top plate 5 has two through holes 31, and a connecting sleeve 32 is installed inside each through hole 31. The connecting sleeve 32 has a hollow structure, and a connecting cover 33 is installed at the upper end of the connecting sleeve 32. The column 13 extends into the connecting sleeve 32 and connects with the connecting cover 33. The middle plate 6 has two corresponding through holes 31, and a second connecting sleeve 34 is installed inside each through hole 31. The second connecting sleeve 34 extends into the through hole 31 and connects with the middle plate 6. The column 13 passes through the second connecting sleeve 34 and connects with the top plate 5. In this embodiment, the function of the connecting sleeve 32 is to enable the top plate 5 to move along the direction of the central axis of the column 13, and at the same time, the connecting sleeve 32 makes the movement of the top plate 5 continuous, stable, and smooth. The connecting cover 33 is connected to the column 13. The diameter of the connecting cover 33 is larger than the diameter of the through hole 31, so that the connecting cover 33 can limit the upward movement of the top plate 5. At the same time, the column 13 provides a moving track for the movement of the top plate 5. The second connecting sleeve 34 also moves in axial direction with the middle plate 6 in conjunction with the column 13. The limiting function of the second connecting sleeve 34 is provided by the compression spring 12.

[0037] Furthermore, one end of the compression spring 12 is connected to the connecting sleeve 32, and the other end is connected to the second connecting sleeve 34. The spring is positioned on the outside of the column 13, saving space and ensuring that the spring's extension and contraction trajectory is the same as the axis of the column 13, further guaranteeing the stability and accuracy of the top plate 5 and the middle plate 6 during movement. During processing, when the power device moves the top plate 5 and the middle plate 6 towards the base 3, the compression spring 12 is compressed, providing a certain buffering effect and preventing excessive impact on the product 4 being processed. When the power device resets the top plate 5 and the middle plate 6, the compression spring 12 provides the middle plate 6 with the power to return to its original position, helping the top plate 5 and the middle plate 6 to reset more easily, thus ensuring the stability and quality of the processing. In addition, the compression spring 12 can also absorb vibrations and noise generated during processing to a certain extent, making the entire processing process smoother and quieter.

[0038] Furthermore, the guide rod 11 is equipped with nuts 35 at both ends to limit the movement of the top plate 5 and the middle plate 6 on the guide rod 11. The guide rod 11 provides a vertical track for the top plate 5 and the middle plate 6, while the nuts 35 limit their movement, preventing them from deviating from the track or wobbling during movement, thus ensuring the stability and accuracy of the machining process. The design of the guide rod 11 takes into account various factors during the machining process, such as the weight, movement speed, and acceleration of the top plate 5 and the middle plate 6, ensuring their smoothness and continuity during movement. During machining, the top plate 5 and the middle plate 6 move up and down along the direction of the guide rod 11. The presence of the guide rod 11 makes this movement more orderly and controllable, thereby ensuring machining accuracy and product quality. In addition, the cooperation between the guide rod 11 and the nuts 35 makes the entire fixture easier and faster to disassemble and assemble, improving work efficiency. In summary, this meticulous design makes the entire shock-absorbing pad press-fit fixture more stable and reliable during use, ensuring processing accuracy and product quality.

[0039] Furthermore, the power unit includes a cylinder and a cylinder bracket. The cylinder is mounted on the cylinder bracket, and one end of the cylinder extends out and is fixedly connected to the positioning block 24. The cylinder drives the top plate 5 to move through the positioning block 24. In this embodiment, the cylinder provides stable power to the pressurizing device 1, while the cylinder bracket is used to house the cylinder and save space for fixture processing. The cylinder, in conjunction with the cylinder bracket, can transmit power in the direction of the fixture (the cylinder and cylinder bracket are not shown in the figure).

[0040] The working principle of this design is as follows: The cylinder connects to the positioning block on the top plate. When the cylinder extends, it drives the top plate and the middle plate to move downwards. After the pressure sleeve on the middle plate moves, it presses tightly onto the product to be processed. At the same time, the fixing head in the fixing device starts to move to fix the product to be processed. Then, the pressure column on the top plate moves downwards and passes through the pressure sleeve to process the product to be processed. During this process, the compression spring starts to tighten, and the elastic element in the base starts to compress downwards due to the action of the product to be processed and the pressure column. After the product is processed, the cylinder drives the top plate and the pressure column on the top plate to move upwards. When the top plate starts to return to its original position, the middle plate also starts to return to its original position under the action of the column and the compression spring. After the product to be processed is processed, the limit spring in the elastic element rebounds and drives the elastic block at the upper end of the limit spring to extend into the slot, so that the product to be processed is pushed out of the base, completing the processing.

[0041] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
