Description

Technical Field

[0001] This utility model relates to an internal hole polishing machine, specifically an internal hole polishing machine for processing aluminum tubes for motorcycle shock absorbers, belonging to the technical field of aluminum tube processing equipment. Background Technology

[0002] In existing motorcycle parts production, the shock absorber rod, which is an aluminum alloy tube, usually requires internal hole polishing to ensure smooth operation of the internal hydraulic damping. The surface quality of the inner hole of the motorcycle shock absorber aluminum tube has a significant impact on the performance of the shock absorber.

[0003] In the prior art, such as the aluminum tube inner hole polishing machine for motorcycle shock absorbers disclosed in announcement number CN202223584228.9, the adjustable inner hole polishing structure allows the device to adjust the outer diameter of the polishing structure according to different models of aluminum tubes, greatly improving the polishing adaptability of the device. Simultaneously, the external polishing structure allows the device to adjust the external polishing according to different models and outer diameters of aluminum tubes. However, the above-mentioned prior art solutions have the following shortcomings: during use, the polishing tool or aluminum tube always acts on a fixed position, which easily leads to excessive material removal at that position. Because the polishing pressure is concentrated at one point, that point and its surrounding area are ground down faster, while the roughness of the surrounding area decreases relatively slowly, ultimately resulting in an uneven polished surface. Furthermore, polishing can only be performed on a small, fixed area. To complete large-area polishing work, it is necessary to constantly move the workpiece or change the polishing position, which increases the complexity and time cost of operation. Utility Model Content

[0004] The purpose of this utility model is to provide a polishing machine for the inner hole of aluminum tubes used in motorcycle shock absorber processing in order to solve at least one of the above-mentioned technical problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a polishing machine for the inner hole of aluminum tubes used in motorcycle shock absorber processing, including a frame;

[0006] The surface of the frame is equipped with a reciprocating polishing assembly, which includes a mounting base fixedly mounted on the surface of the frame. A servo motor is installed inside the mounting base. A transmission rod is installed on the output shaft end of the servo motor. A sliding connecting sleeve is slidably connected to the outside of the transmission rod. The inner wall of the sliding connecting sleeve is integrally formed with a sliding protrusion. The sliding connecting sleeve is slidably connected to a wavy spiral groove opened on the surface of the transmission rod through the sliding protrusion. The other end of the sliding connecting sleeve is internally threaded with a connecting rod. One end of the connecting rod is integrally formed with a polishing head.

[0007] As a further embodiment of this utility model: one end of the sliding connecting sleeve is integrally formed with a slip ring, the surface of the slip ring is slidably connected with a rotating connecting block, a T-shaped guide rod is fixedly installed on one side of the rotating connecting block, a fixed support plate is slidably connected to the surface of the T-shaped guide rod, and the fixed support plate is fixedly installed on the surface of the frame.

[0008] As a further improvement of this utility model, the transmission rod is rotatably connected to a through hole opened on the surface of the fixed support plate.

[0009] As a further embodiment of this utility model: the surface of the connecting rod is integrally formed with a locking block, the outer surface of the connecting rod is slidably connected with a pressure sleeve, and a limit bolt is threadedly connected to the threaded hole on the surface of the pressure sleeve. One end of the limit bolt, which passes through the pressure sleeve, is threadedly connected to the threaded hole on the surface of the sliding connecting sleeve.

[0010] As a further embodiment of this utility model: an auxiliary clamping assembly is installed on the surface of the frame. The auxiliary clamping assembly includes a fixed frame fixedly installed on the surface of the frame. A slide rod is fixed on one side of the fixed frame, and a fixed plate is fixed on one end of the slide rod. The fixed plate is fixedly installed on the surface of the frame. Hydraulic rods are symmetrically installed on one side of the fixed plate. A sliding frame is connected to the same end of the two hydraulic rods. The sliding frame is slidably connected to the surface of the slide rod. Multiple conical clamps are arranged in a ring on one side of the sliding frame. A guide block is installed on the same side of the multiple conical clamps. The conical clamps are slidably connected to the grooves opened on the surface of the sliding frame through the guide blocks. The surface of the fixed frame is provided with conical grooves.

[0011] As a further embodiment of this utility model: a guide rod is slidably connected to the surface of the guide block, the guide rod is installed in a groove opened on the surface of the sliding frame, a spring is sleeved on the outer surface of the guide rod and on one side of the guide block, and anti-slip pads are provided on the clamping surfaces of multiple cone clamps.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a reciprocating polishing assembly. Through the coordinated use of the transmission rod, wavy spiral groove, sliding connecting sleeve, slip ring, rotating connecting block, T-shaped guide rod and polishing head, the rotation of the transmission rod causes the sliding connecting sleeve to reciprocate linearly on the transmission rod. The reciprocating motion of the sliding connecting sleeve is transmitted to the polishing head through the connecting rod, so that the polishing head performs reciprocating polishing operation in the inner hole of the aluminum tube. Reciprocating polishing can cover a large surface area in one reciprocating motion. Compared with fixed-point polishing, which processes one point or small area at a time, it greatly improves polishing efficiency. In the whole polishing process, there is no need for frequent stops and adjustments as with fixed-point polishing, which makes the transition between polishing areas smoother, thereby reducing surface stress concentration and obtaining a uniform polishing effect.

[0014] The polishing head is detachably installed inside one end of the sliding connecting sleeve via a threaded connection using a connecting rod. When wear and damage occur after prolonged use, or when a different size polishing head needs to be replaced, the old polishing head can be easily unscrewed from the sliding connecting sleeve. This installation method allows operators to quickly replace the appropriate polishing head without the need for complex disassembly and reassembly of the entire polishing equipment. Compared to some non-detachable or complexly connected polishing heads, this significantly shortens replacement time and improves work efficiency.

[0015] 2. This utility model is equipped with an auxiliary clamping assembly. Through the coordinated use of the fixed frame, conical groove, sliding frame, guide rod, guide block, spring, conical clamp, and anti-slip pad, multiple conical clamps installed on one side of the sliding frame slide into the conical groove opened near the surface of the fixed frame until the multiple conical clamps move closer to the surface of the aluminum tube under the action of the conical groove, until the aluminum tube is clamped in the multiple conical clamps, thereby achieving the limiting and fixing of the aluminum tube to be processed. The self-centering and self-locking characteristics of the conical clamps can apply clamping force to the aluminum tube evenly from multiple directions, ensuring that the aluminum tube will not shake, shift, or rotate during the polishing process, thereby ensuring the uniformity and accuracy of polishing.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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. Example 1

[0024] like Figures 1 to 6 As shown, a polishing machine for the inner hole of aluminum tubes used in motorcycle shock absorber processing includes a frame 1.

[0025] The surface of the frame 1 is equipped with a reciprocating polishing assembly 2, which includes a mounting base 21, a servo motor 22, a transmission rod 23, a wavy spiral groove 24, a sliding connecting sleeve 25, a slip ring 26, a rotating connecting block 27, a T-shaped guide rod 28, a fixed support plate 29, a connecting rod 210, a polishing head 211, a pressure sleeve 212, a limit bolt 213, a locking block 214, and a sliding protrusion 215.

[0026] A mounting base 21 is fixedly mounted on the surface of the frame 1. A servo motor 22 is installed inside the mounting base 21. A transmission rod 23 is installed on the output shaft end of the servo motor 22. A sliding connecting sleeve 25 is slidably connected to the outside of the transmission rod 23. A sliding protrusion 215 is integrally formed on the inner wall of the sliding connecting sleeve 25. The sliding connecting sleeve 25 is slidably connected to the wavy spiral groove 24 opened on the surface of the transmission rod 23 through the sliding protrusion 215. A connecting rod 210 is internally threaded to the other end of the sliding connecting sleeve 25. A polishing head 211 is integrally formed on one end of the connecting rod 210.

[0027] The rotation of the transmission rod 23 causes the sliding connecting sleeve 25 to reciprocate linearly on the transmission rod 23. The reciprocating motion of the sliding connecting sleeve 25 is transmitted to the polishing head 211 through the connecting rod 210, so that the polishing head 211 performs reciprocating polishing operation in the inner hole of the aluminum tube. Reciprocating polishing can cover a large surface area in one reciprocating motion. Compared with fixed-point polishing, which processes one point or small area at a time, it greatly improves polishing efficiency. In the whole polishing process, there is no need for frequent stops and adjustments as with fixed-point polishing, which makes the transition between polishing areas smoother, thereby reducing surface stress concentration and achieving a uniform polishing effect.

[0028] One end of the sliding connecting sleeve 25 is integrally formed with a slip ring 26. A rotating connecting block 27 is slidably connected to the surface of the slip ring 26. A T-shaped guide rod 28 is fixedly installed on one side of the rotating connecting block 27. A fixed support plate 29 is slidably connected to the surface of the T-shaped guide rod 28. The fixed support plate 29 is fixedly installed on the surface of the frame 1.

[0029] During the polishing process, the T-shaped guide rod 28 and the fixed support plate 29 provide stable guidance for the movement of the sliding connecting sleeve 25, ensuring that the polishing head 211 can make precise reciprocating movements along the axial direction of the inner hole of the aluminum tube, thereby achieving uniform polishing of the inner hole of the aluminum tube.

[0030] The transmission rod 23 is rotatably connected to the through hole opened on the surface of the fixed support plate 29.

[0031] The connecting rod 210 has a locking block 214 integrally formed on its surface. The outer surface of the connecting rod 210 is slidably connected to a pressure sleeve 212. A limit bolt 213 is threadedly connected to the threaded hole on the surface of the pressure sleeve 212. One end of the limit bolt 213, which passes through the pressure sleeve 212, is threadedly connected to the threaded hole on the surface of the sliding connecting sleeve 25.

[0032] It can improve the stability of the polishing head 211 installed inside one end of the sliding connecting sleeve 25 by means of a threaded detachable installation via the connecting rod 210. It can effectively prevent the polishing head 211 from loosening due to external forces such as vibration, torsion and axial tension. Through the synergistic effect of these components, the reliability of the connection between the polishing head 211 and the sliding connecting sleeve 25 is greatly enhanced, ensuring that the polishing operation can be carried out continuously and stably. Example 2

[0033] In addition to all the technical features included in Embodiment 1, this embodiment also includes:

[0034] An auxiliary clamping assembly 3 is installed on the surface of the frame 1. The auxiliary clamping assembly 3 includes a fixed frame 31, a conical groove 32, a slide bar 33, a fixed plate 34, a hydraulic rod 35, a sliding frame 36, a guide rod 37, a guide block 38, a spring 39, a conical clamp 310, and an anti-slip pad 311.

[0035] A fixing frame 31 is fixedly installed on the surface of the frame 1. A slide rod 33 is fixed on one side of the fixing frame 31. A fixing plate 34 is fixed to one end of the slide rod 33. The fixing plate 34 is fixedly installed on the surface of the frame 1. Hydraulic rods 35 are symmetrically installed on one side of the fixing plate 34. A sliding frame 36 is connected to the same end of the two hydraulic rods 35. The sliding frame 36 is slidably connected to the surface of the slide rod 33. Multiple conical clamps 310 are arranged in a ring on one side of the sliding frame 36. A guide block 38 is installed on the same side of the multiple conical clamps 310. The conical clamps 310 are slidably connected to the grooves opened on the surface of the sliding frame 36 through the guide blocks 38. A conical groove 32 is opened on the surface of the fixing frame 31.

[0036] Activating the hydraulic rod 35 causes the sliding frame 36 to slide on the sliding rod 33, causing multiple conical clamps 310 mounted on one side of the sliding frame 36 to slide into the conical grooves 32 opened near the surface of the fixed frame 31, until the multiple conical clamps 310 move closer to the surface of the aluminum tube under the action of the conical grooves 32, until the aluminum tube is clamped in the multiple conical clamps 310, thereby achieving the limiting and fixing of the aluminum tube to be processed. The self-centering and self-locking characteristics of the conical clamps 310 can apply clamping force to the aluminum tube evenly from multiple directions, ensuring that the aluminum tube will not shake, shift or rotate during the polishing process, thereby ensuring the uniformity and accuracy of polishing.

[0037] A guide rod 37 is slidably connected to the surface of the guide block 38. The guide rod 37 is installed in a groove on the surface of the sliding frame 36. A spring 39 is sleeved on the outer surface of the guide rod 37 and on one side of the guide block 38. Anti-slip pads 311 are provided on the clamping surfaces of multiple cone clamps 310.

[0038] The anti-slip pads 311 prevent the aluminum tube from rotating or shifting during polishing, further improving the stability of the aluminum tube.

[0039] Working principle: In use, firstly, the aluminum tube of the motorcycle shock absorber to be polished is inserted through the through hole on the fixing plate 34 and then through the conical groove 32 on the surface of the fixing frame 31. Then, the hydraulic rod 35 is activated, causing the sliding frame 36 to slide on the sliding rod 33. This causes multiple conical clamps 310 installed on one side of the sliding frame 36 to slide into the conical groove 32 near the surface of the fixing frame 31. This continues until the multiple conical clamps 310 move closer to the surface of the aluminum tube under the action of the conical groove 32, until the aluminum tube is clamped in the multiple conical clamps 310, thus achieving the limiting and fixing of the aluminum tube to be processed. The self-centering and self-locking characteristics of the conical clamps 310 can apply clamping force evenly to the aluminum tube from multiple directions, ensuring that the aluminum tube will not shake, shift or rotate during the polishing process, thereby ensuring the uniformity and accuracy of polishing.

[0040] The anti-slip pads 311 prevent the aluminum tube from rotating or shifting during polishing, further improving the stability of the aluminum tube.

[0041] When the multiple cone clamps 310 move towards the surface of the aluminum tube under the action of the cone groove 32, they can move smoothly to one side of the aluminum tube under the limiting guidance of the guide rod 37 and the guide block 38, while the spring 39 can be compressed.

[0042] Then, the servo motor 22 is started, causing the servo motor 22 to drive the transmission rod 23 to rotate. Since the sliding connecting sleeve 25 is slidably connected to the wave-shaped spiral groove 24 opened on the surface of the transmission rod 23 through the sliding protrusion 215, the rotation of the transmission rod 23 will cause the sliding connecting sleeve 25 to perform reciprocating linear motion on the transmission rod 23. The reciprocating motion of the sliding connecting sleeve 25 is transmitted to the polishing head 211 through the connecting rod 210, so that the polishing head 211 performs reciprocating polishing operation in the inner hole of the aluminum tube. Reciprocating polishing can cover a large surface area in one reciprocating motion. Compared with fixed-point polishing, which processes point by point or small area by area, it greatly improves the polishing efficiency. In the whole polishing process, there is no need for frequent stops and adjustments as with fixed-point polishing, which can make the transition between polishing areas smoother, thereby reducing surface stress concentration and obtaining a uniform polishing effect.

[0043] During the polishing process, the T-shaped guide rod 28 and the fixed support plate 29 provide stable guidance for the movement of the sliding connecting sleeve 25, ensuring that the polishing head 211 can make precise reciprocating movements along the axial direction of the inner hole of the aluminum tube, thereby achieving uniform polishing of the inner hole of the aluminum tube.

[0044] The polishing head 211 is installed inside one end of the sliding connecting sleeve 25 via a threaded connection through the connecting rod 210. When the polishing head 211 wears out or is damaged after long-term use, or when it needs to be replaced with a different size polishing head 211, the old polishing head 211 can be easily unscrewed from the inside of one end of the sliding connecting sleeve 25 through the threaded detachable installation method. This installation method allows the operator to quickly replace the appropriate polishing head 211 without the need for complicated disassembly and reassembly of the entire polishing equipment. Compared with some non-detachable or complexly connected polishing heads 211, this method greatly shortens the replacement time and improves work efficiency.

[0045] The combination of the pressure sleeve 212, the locking block 214, and the limiting bolt 213 improves the stability of the polishing head 211 when it is installed inside one end of the sliding connecting sleeve 25 via the connecting rod 210 in a detachable manner using a threaded connection. This effectively prevents the polishing head 211 from loosening due to external forces such as vibration, torsion, and axial tension. Through the synergistic effect of these components, the reliability of the connection between the polishing head 211 and the sliding connecting sleeve 25 is greatly enhanced, ensuring that the polishing operation can be carried out continuously and stably.
