Description

Technical Field

[0001] This utility model mainly relates to the technical field of nitrogen spring processing, specifically a clamping mechanism for nitrogen spring processing. Background Technology

[0002] Nitrogen springs are a new type of elastic component that uses high-pressure nitrogen gas as its working medium. They are also known as die nitrogen springs, nitrogen cylinders, or nitrogen cylinders. A nitrogen spring is filled with high-pressure nitrogen gas in a sealed container. When an external force compresses the nitrogen gas through a plunger rod, the nitrogen gas volume decreases and its pressure increases, thus storing external energy in the form of compressed gas. Once the external force disappears, the high-pressure nitrogen gas pushes the piston outward, releasing the previously stored energy and achieving a rebound or reset function. As a precision elastic component, the machining accuracy of a nitrogen spring directly affects its performance and service life. During machining, unstable clamping or uneven clamping force may cause deformation or displacement of the nitrogen spring, affecting its geometric dimensions and shape accuracy. Therefore, using a stable and reliable clamping method can ensure the machining accuracy of the nitrogen spring and meet design requirements.

[0003] According to application number CN202320679521.9, a clamping fixture for processing nitrogen springs includes a base. A motor is screwed to the right side of the top of the base. One end of a screw is installed on the output end of the lower surface of the motor. The other end of the screw extends into the inner cavity of the base. The bottom end of the screw is rotatably connected to the right side of the bottom end of the inner cavity of the base via a bearing. A clamping plate is threaded to the outer wall of the screw. The left side of the clamping plate extends out of the left end face of the base. A base plate is installed at the top of the base. A gear is rotatably connected to the center of the inner cavity of the base plate via a bearing.

[0004] In the existing technology, the nitrogen spring clamping mechanism has poor clamping stability and poor adaptability, and cannot meet the existing processing requirements of various specifications. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a clamping mechanism for processing nitrogen springs, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A clamping mechanism for processing nitrogen springs includes a jacking slide rod. Limiting clamping plates are slidably connected to both sides of the jacking slide rod. A clamping base is sleeved on the outer wall of the limiting clamping plates and slidably connected to the top and bottom of the jacking slide rod. A slide rail is provided at the bottom of one end of the clamping base. A slider is sleeved on the outer wall of the slide rail. A driving cylinder is provided at one end of the slider. The jacking slide rod is located at the top of the slider.

[0008] Preferably, one end of the jacking slide rod is provided with a trapezoidal top block, and both sides of the trapezoidal top block and the side wall of the limiting clamp are provided with inclined surfaces; the two sides of the trapezoidal top block are slidably connected to the inclined surfaces.

[0009] Preferably, the limiting clamp is provided with a set of arc-shaped grooves on the other side, the limiting clamp is provided with limiting strips at the top and bottom, the limiting clamp is provided with a limiting rod one on the other side wall of the limiting clamp and located on the side of the arc-shaped groove, and the limiting clamp is provided with a limiting rod two on one side of the limiting clamp and located on the side of the inclined surface.

[0010] Preferably, the top of the clamping base is provided with multiple part placement slots arranged in an array, the inner wall of the clamping base is provided with a return spring, and the inner wall of the clamping base and the side near where the slide rail is provided are provided with a limiting through hole, and the inner wall of the limiting through hole is provided with a pressure sensor.

[0011] Preferably, the other end of the reset spring is embedded in the side wall of the limiting clamp, and the limiting through hole is slidably connected to the limiting rod.

[0012] Preferably, the bottom and top of the inner wall of the clamping base are further provided with limiting grooves, and the inner wall of the limiting groove is slidably connected to the outer wall of the limiting strip.

[0013] Preferably, the arc-shaped groove is located on one side of the part placement slot.

[0014] In summary, this technical solution has the following main advantages:

[0015] This invention achieves rapid and stable clamping and release of the limiting clamp by using a drive cylinder to move the sliding rod and trapezoidal top block. This mechanism not only improves processing efficiency but also ensures stability and accuracy during clamping, thus enhancing the processing quality of nitrogen springs.

[0016] Furthermore, the arc-shaped groove design on the limiting clamp allows it to closely conform to the surface of cylindrical workpieces such as nitrogen springs, achieving self-adaptive clamping. This design enhances the versatility of the clamping mechanism, making it suitable for machining nitrogen springs of different specifications and sizes, and reducing the cost and time of changing fixtures.

[0017] Meanwhile, the entire clamping mechanism adopts a modular design, making it compact and easy to assemble and disassemble. This not only facilitates daily maintenance and upkeep but also helps reduce failure rates and repair costs, extending the equipment's lifespan. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] like Figures 1 to 4 As shown, a clamping mechanism for processing nitrogen springs includes a pusher slide rod 10, with limit clamping plates 11 slidably connected to both sides of the pusher slide rod 10. A clamping base 12 is sleeved on the outer wall of the limit clamping plates 11 and slidably connected to the top and bottom of the pusher slide rod 10. A slide rail 13 is provided at the bottom of one end of the clamping base 12. A slider 14 is sleeved on the outer wall of the slide rail 13. A drive cylinder 15 is provided at one end of the slider 14. The pusher slide rod 10 is located on the top of the slider 14.

[0026] One end of the jacking slide rod 10 is provided with a trapezoidal top block 101, and both sides of the trapezoidal top block 101 and the side wall of the limiting clamp 11 are provided with inclined surfaces 111; the two sides of the trapezoidal top block 101 are slidably connected to the inclined surfaces 111.

[0027] The limiting clamp 11 has a set of arc-shaped grooves 112 on the other side, and the limiting clamp 11 has a limiting strip 113 at the top and bottom. The limiting clamp 11 has a limiting rod 114 on the side wall of the other end of the limiting clamp 11 and located on the side of the arc-shaped groove 112, and a limiting rod 115 on one side of the limiting clamp 11 and located on the side of the inclined surface 111.

[0028] The top of the clamping base 12 is provided with multiple part placement slots 121 arranged in an array. The inner wall of the clamping base 12 is provided with a return spring 122. The inner wall of the clamping base 12 and the side near the slide rail 13 is provided with a limiting through hole 123. The inner wall of the limiting through hole 123 is provided with a pressure sensor 124.

[0029] The other end of the reset spring 122 is embedded in the side wall of the limiting clamp 11, and the limiting through hole 123 is slidably connected to the limiting rod 114.

[0030] The bottom and top of the inner wall of the clamping base 12 are also provided with a limiting long groove 125, and the inner wall of the limiting long groove 125 is slidably connected to the outer wall of the limiting long strip 113.

[0031] The arc-shaped groove 112 is located on one side of the part placement groove 121.

[0032] It should be noted that, in this embodiment, the clamping mechanism mainly includes a jacking slide rod 10, with limiting clamping plates 11 slidably connected to both sides of the jacking slide rod 10; in order to ensure the stable sliding of the limiting clamping plates 11 on the jacking slide rod 10, a clamping base 12 is sleeved on the top and bottom of the jacking slide rod 10 and slidably connected to the outer wall of the limiting clamping plates 11; a slide rail 13 is provided at the bottom of one end of the clamping base 12, and a slider 14 is sleeved on the outer wall of the slide rail 13, with a drive cylinder 15 fixed at one end of the slider 14; the jacking slide rod 10 is installed on the top of the slider 14, so when the drive cylinder 15 works, the jacking slide rod 10 can be moved by the slider 14;

[0033] Furthermore, one end of the pusher slide 10 is provided with a trapezoidal top block 101, and one side wall of the limiting clamp 11 is provided with an inclined surface 111 that matches the two sides of the trapezoidal top block 101; when the pusher slide 10 moves, the trapezoidal top block 101 will slide along the inclined surface 111, thereby pushing the limiting clamp 11 to perform clamping or releasing actions.

[0034] On the other side of the limiting clamping plate 11, there is a set of arc-shaped grooves 112. These arc-shaped grooves 112 can be used to better clamp cylindrical workpieces such as nitrogen springs. At the same time, the top and bottom of the limiting clamping plate 11 are provided with limiting strips 113. These limiting strips 113 can slide within the limiting grooves 125 of the clamping base 12 to ensure the stable movement of the limiting clamping plate 11.

[0035] In addition, a limiting rod 114 is provided on the other side wall of the limiting clamp 11 and on one side of the arc groove 112, while a limiting rod 115 is provided on one side of the limiting clamp 11 and on one side of the inclined surface 111.

[0036] The top of the clamping base 12 is arranged with multiple part placement slots 121, which can be used to place workpieces such as nitrogen springs to be processed. The inner wall of the clamping base 12 is provided with a return spring 122, the other end of which is embedded in the side wall of the limiting clamping plate 11 to help the limiting clamping plate 11 return to its original position after the clamping action is completed. The inner wall of the clamping base 12 and the side near the slide rail 13 is provided with a limiting through hole 123, and the inner wall of the limiting through hole 123 is provided with a pressure sensor 124. When the limiting rod 114 slides in the limiting through hole 123, it will trigger the pressure sensor 124, thereby enabling real-time monitoring of the clamping status of the clamping mechanism.

[0037] The working principle of this utility model is as follows:

[0038] In practical applications, when it is necessary to clamp workpieces such as nitrogen springs, the drive cylinder 15 can be activated to push the slider 14 and the push rod 10 forward. The trapezoidal top block 101 at one end of the push rod 10 will slide along the inclined surface 111 of the limiting clamping plate 11, pushing the limiting clamping plate 11 closer to the workpiece until the arc groove 112 clamps the workpiece. At this time, the limiting rod 114 will slide in the limiting through hole 123 and trigger the pressure sensor 124, indicating that the clamping action has been completed. When it is necessary to release the workpiece, simply reverse the operation of the drive cylinder 15. The return spring 122 will help the limiting clamping plate 11 return to the initial position after the clamping action is completed.

[0039] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
