Technical Field
[0001] This utility model relates to the field of gas spring tube processing technology, and in particular to a gas spring outer tube grinding device. Background Technology
[0002] A gas spring is a mechanical component that utilizes the compressibility and restoring force of gas to achieve functions such as support, buffering, and shock absorption. It typically consists of a sealed pressure vessel (cylinder), a piston rod, and compressed gas filling the interior. When an external force is applied to the piston rod, it changes the volume of the gas inside the cylinder, thereby generating a corresponding pressure change. This pressure change can be used to provide support or absorb impact energy. The pressure vessel is composed of a relatively robust metal outer tube. After production, the outer tube needs to be polished to remove burrs and uneven parts on the surface, achieving a smooth surface for ease of use.
[0003] Existing grinding devices for outer tubes mainly consist of a pair of grinding drive rollers driven by a motor and guide support assemblies located on both sides of the grinding drive rollers. The guide support assemblies include restrictive guide tubes for the stable passage of the outer tube to be ground. Their function is to keep the outer tube stable as it passes between the two grinding drive rollers, allowing the outer tube to be ground smoothly. However, since the restrictive guide tube in the guide support assembly is an integrated fixed-size tube, and the distance between the two grinding drive rollers in the device is also fixed, the device can only grind outer tubes with a fixed outer diameter. It is difficult to meet the grinding needs of outer tubes with different outer diameters. Grinding outer tubes of different sizes and specifications requires the use of multiple sets of compatible equipment, which increases the cost of use. The overall versatility of the device is low, and its practicality is not strong.
[0004] Therefore, in the existing external tube grinding devices, the limiting guide tube used to restrict the grinding of the external tube in the guide support assembly is an integrated fixed-size pipe. The device also needs to be coordinated and modified, resulting in grinding work only for external tubes with a fixed outer diameter. It is difficult to meet the grinding needs of external tubes with different outer diameters. Grinding external tubes of different sizes and specifications requires the use of multiple sets of matching equipment, which increases the cost of use. The overall device has low versatility and poor practicality. A gas spring external tube grinding device can be designed. The limiting guide tube with a suitable diameter is selected according to the diameter of the external tube to be ground. The limiting guide tube is fixed to the mounting plate by two clamping plates and two clamping plates. Then, the position and height are adjusted by starting the cylinder, so that the external tube to be ground can stably pass between the two transmission grinding rollers for grinding.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1-4 This utility model provides an embodiment of a gas spring outer tube grinding device, including a base plate 1; it also includes a clamping plate 12 and a clamping plate 14. A support plate 2 is fixedly connected to the upper middle part of the base plate 1 via a support member. U-shaped frames 3 are symmetrically fixedly connected to the left and right sides of the upper end of the support plate 2. A transmission grinding roller 4 is rotatably connected to the inner side of each of the two U-shaped frames 3. Cylinders 5 are symmetrically fixedly connected to the front and rear sides of the upper end of the base plate 1. The movable ends of the two cylinders 5 are jointly fixedly connected to a support frame 6. An mounting plate 8 and a receiving plate 7 are fixedly connected to the front and rear sides of the upper end of the support frame 6, respectively. A limiting guide tube 9 is provided at the upper end of the mounting plate 8. A through groove 10 is opened through the middle of the mounting plate 8. Moving plates 11 are symmetrically arranged through the left and right sides of the through groove 10. A clamping plate 1 is fixedly connected to the upper end of the two moving plates 11 to clamp the limiting guide tube 9 from left and right. 12. N-type plates 13 are symmetrically fixedly connected to the front and rear sides of the upper end of the mounting plate 8. The inner sides of the two N-type plates 13 are provided with clamping plates 14 that press the limiting guide tube 9 downward. First, select a limiting guide tube 9 with an appropriate diameter according to the diameter of the outer tube to be ground. Place the limiting guide tube 9 on the upper end of the mounting plate 8. Then, control the two clamping plates 12 to clamp it in the left and right positions and control the two clamping plates 14 to clamp it in the up and down direction, thereby fixing the limiting guide tube 9 directly above the mounting plate 8. Then, start the two cylinders 5 to raise the receiving plate 7 and the mounting plate 8 to a suitable height. Insert the outer tube to be ground into the limiting guide tube 9 in sequence and pass it between the two transmission grinding rollers 4. Control the two transmission grinding rollers 4 to work while grinding the outer tube and convey it backward. The ground outer tube is conveyed to the surface of the receiving plate 7 for removal.
[0023] Please see Figure 1 , Figure 3 and Figure 4In this embodiment, an N-type plate 15 is fixedly connected to the bottom center of the mounting plate 8. A bidirectional screw 16 is rotatably connected to the inner side of the N-type plate 15, and the lower ends of the two movable plates 11 are symmetrically threaded to the outer side of the bidirectional screw 16. A knob 17 is rotatably connected to the left end of the N-type plate 15. The knob 17 is fixedly connected to the bidirectional screw 16 via a rotating shaft. Rotating the knob 17 drives the bidirectional screw 16 to rotate, and the bidirectional screw 16 drives the two movable plates 11 to move relative to each other. A threaded rod 18 is threaded through the upper end. The bottom of the threaded rod 18 is rotatably connected to the surface of the clamping plate 14. A knob 19 is fixedly connected to the top of the threaded rod 18. Rotating the knob 19 causes the threaded rod 18 to rotate, and the threaded rod 18 pushes the clamping plate 14 to move up and down. A motor 20 is fixedly connected to the front end of the U-shaped frame 3. The output shaft of the motor 20 is fixedly connected to the mounting shaft of the corresponding transmission grinding roller 4. Starting the motor 20 drives the transmission grinding roller 4 to rotate and perform grinding and conveying work.
[0024] Please see Figures 1-2 In this embodiment, a U-shaped frame 21 is fixedly connected to the upper end of the support plate 2. A vacuum pump 22 is fixedly connected to the upper right side of the U-shaped frame 21. A vacuum pipe 23 is fixedly connected to the suction port of the vacuum pump 22. The end of the vacuum pipe 23 away from the vacuum pump 22 passes through the inner side of the U-shaped frame 21 and is fixedly connected to a suction cover 24. When the vacuum pump 22 is started, the waste generated during the grinding process is absorbed through the vacuum pipe 23. A waste collection box 25 is fixedly connected to the upper left side of the U-shaped frame 21. An exhaust pipe 26 is fixedly connected to the exhaust port of the vacuum pump 22. The end of the 6th plate away from the vacuum pump 22 is fixedly connected to the waste collection box 25. The vacuum pump 22 absorbs the waste generated during the grinding process and then conveys the waste to the waste collection box 25 for collection. The rear end of the receiving plate 7 is fixedly connected to the inclined discharge plate 27. The upper left and right sides of the receiving plate 7 and the inclined discharge plate 27 are symmetrically fixedly connected to the continuous baffles 28. The ground outer tube that falls onto the receiving plate 7 is further pushed onto the inclined discharge plate 27, and then slides down into the material collection frame below for collection. The baffles 28 can prevent the outer tube from sliding to the left and right sides.
[0025] During operation, first select a suitable diameter limiting guide tube 9 based on the diameter of the outer tube to be ground. Place the limiting guide tube 9 on the upper end of the mounting plate 8. Turn knob 17 to drive the double-acting screw 16 to rotate. The double-acting screw 16 drives the two moving plates 11 to move closer to each other, causing the two clamping plates 12 to clamp the limiting guide tube 9 to the left and right. Further turn knobs 29 to drive the threaded rod 18 to rotate. The threaded rod 18 pushes the clamping plate 2 14 downward to clamp the limiting guide tube 9, thereby fixing the limiting guide tube 9 directly above the mounting plate 8. Then, activate the two cylinders 5 to raise the tube. At the appropriate heights of the receiving plate 7 and the mounting plate 8, the outer tube to be ground is sequentially inserted into the limiting guide tube 9 and passed between the two transmission grinding rollers 4. The two motors 20 are started to drive the transmission grinding rollers 4 to rotate, grinding the outer tube while conveying it backward. The ground outer tube is conveyed to the surface of the receiving plate 7 and slides down the inclined discharge plate 27 into the material collection box placed below. During the grinding process, the air pump 22 is started to absorb the waste generated during the grinding process through the air extraction pipe 23, and then transport it into the waste collection box 25 through the air outlet pipe 26 for collection.
[0026] Through the above steps, a suitable diameter limiting guide tube 9 can be selected according to the diameter of the outer tube to be ground. The limiting guide tube 9 is fixed on the mounting plate 8 by two clamping plates 12 and two clamping plates 14. Then, its position and height are adjusted by starting the cylinder 5, so that the outer tube to be ground can stably pass between the two transmission grinding rollers 4 for grinding. This adapts to the grinding needs of outer tubes with different diameters, increases the versatility and practicality of the device, reduces the cost of purchasing special grinding equipment, and reduces expenses. This solves the problem that in existing outer tube grinding devices, the limiting guide tube 9 used to limit and guide the outer tube in the guide support assembly is an integrated fixed-size pipe, and the device cannot be coordinated and changed, resulting in grinding work only for outer tubes with fixed outer diameters. It is difficult to meet the grinding needs of outer tubes with different outer diameters. Grinding outer tubes of different sizes and specifications requires the use of multiple sets of matching equipment, which increases the cost of use. The overall versatility of the device is low and its practicality is not strong.
