Description

Technical Field

[0001] This application relates to the field of automotive pipe processing equipment technology, and in particular to a deburring device for automotive pipe ends. Background Technology

[0002] In the automotive manufacturing industry, pipe fittings are an important component of key parts such as fuel delivery, braking systems, and cooling circulation. Their processing quality directly affects the performance and safety of the entire vehicle. Burrs at the pipe fitting ends can not only cause deviations in the inner diameter of the pipe fitting, affecting fluid transmission efficiency, but may also scratch seals during assembly, leading to malfunctions such as oil and air leaks, and even threatening driving safety.

[0003] A search revealed a patent document with authorization announcement number CN221984644U, which discloses a deburring device for automotive pipe fittings. The device includes a fixing mechanism and a grinding mechanism. The fixing mechanism includes a base, on one side of which a cylinder is fixedly mounted via a connecting plate. A push block is fixedly connected to the piston rod of the cylinder. Two movable blocks are tightly attached to the outer side of the push block. A connecting block is fixedly connected to the opposite side of each of the two movable blocks. A rotating shaft is rotatably connected inside the connecting block, and the bottom end of the rotating shaft is fixedly connected to the base. Springs are fixedly connected to the opposite side of each of the two movable blocks. This deburring device, through the fixing and grinding mechanisms, allows the cylinder to drive the push block to press against the two movable blocks after the pipe fitting is mounted on them. This, in turn, allows the rotating movable blocks to press firmly against the inner wall of the pipe fitting. This design solves the problem of pipe fittings easily shifting during deburring, thereby improving the efficiency of deburring.

[0004] In practical use, it was found that although the existing equipment has a certain deburring capability, the clamping and fixing method is simple and cannot provide stable support from both the inside and outside of the pipe. As a result, the pipe is prone to vibration or displacement during the grinding process, which affects the deburring accuracy and surface quality. Therefore, we proposed a deburring device for automotive pipe ends to solve the above problems. Utility Model Content

[0041] Specifically, the second gear mechanism includes three second conical wheels 9. The other end of the first rotating shaft 501 and the output shaft of the second motor 401 are both fixedly fitted with second conical wheels 9. The second conical wheels 9 are located to the right of the first conical wheel 8. The three second conical wheels 9 mesh with each other. The third gear mechanism includes four third conical wheels 10. The first rotating shaft 501 and the right end of the second rotating shaft 502 are both fixedly fitted with third conical wheels 10. The third conical wheels 10 are located inside the fixed box 5. The corresponding two third conical wheels 10 mesh with each other.

[0042] Specifically, the lead screw mechanism includes a lead screw 601 and a lead screw seat 602. The same lead screw 601 is rotatably installed on the inner wall of the top and the inner wall of the bottom of the connecting box 6. The lead screw seat 602 is threaded on the lead screw 601. A fourth gear mechanism is provided between the lead screw 601 and the second rotating shaft 502.

[0043] Specifically, the fourth gear mechanism includes four fourth conical wheels 11. The fourth conical wheels 11 are fixedly sleeved on the lead screw 601 and the left end of the second rotating shaft 502. The fourth conical wheels 11 are located outside the lead screw seat 602, and two corresponding fourth conical wheels 11 mesh with each other.

[0044] Specifically, the clamping mechanism includes two connecting rods 603, two arc-shaped clamps 604, and two arc-shaped clamping pads 605. The connecting rods 603 are fixedly installed on the right side of the lead screw seat 602. One end of the connecting rod 603 passes through the connecting box 6, and the arc-shaped clamps 604 are fixedly installed on the other end of the connecting rod 603. The arc-shaped clamps 604 are provided with arc-shaped clamping pads 605 on their inner walls.

[0045] In this application, during operation, one end of the pipe fitting is first fitted onto the outside of the support box 4. By starting the second motor 401, its output shaft drives the first conical wheel 8 connected to it to rotate. Through the first gear mechanism composed of two meshing first conical wheels 8, the bidirectional screw 402 can be driven to rotate. Since the threads at both ends of the bidirectional screw 402 turn in opposite directions, the two screw seats 403 on it move in opposite directions under the action of thread transmission, thereby pushing the top rod 404 of the tightening mechanism to extend, which can drive the arc-shaped top seat 405 and the outer arc-shaped top pad 406 to tightly press against the inner wall of the pipe fitting. The arc-shaped top pad 406 is made of a high friction coefficient material, which can increase the friction with the inner wall of the pipe fitting to prevent axial movement of the pipe fitting, and avoid scratching the surface of the pipe fitting, thus achieving the purpose of stable tightening and fixing of the inner wall of the pipe fitting.

[0046] Meanwhile, the output shaft of the second motor 401 drives the first rotating shaft 501 to rotate through the second gear mechanism composed of three second conical wheels 9. The first rotating shaft 501 then drives the second rotating shaft 502 to rotate through two corresponding third conical wheels 10. The second rotating shaft 502 drives the lead screw 601 to rotate through two corresponding fourth conical wheels 11, which causes the lead screw seat 602 on the lead screw 601 to move along the thread direction. This allows the arc-shaped clamp 604 and the arc-shaped clamp 605 on the inner wall to close towards the outside of the pipe through the connecting rod 603. This achieves the purpose of synchronous and stable clamping of the outside of the pipe, thereby applying stable pressure from both the inside and outside of the pipe to form a comprehensive fixing effect, ensuring that the pipe will not shift or shake during subsequent processing.

[0047] After fixing, the electric push rod 201 is activated, pushing the push plate 202 to move the motor housing 3, support box 4, and the fixed pipe fitting smoothly, adjusting the pipe fitting to the grinding position. Subsequently, the hydraulic cylinder 701 is activated, and its output shaft pushes the lifting plate to drive the grinder 702 and grinding wheel 703 to precisely descend to the position to be ground at the pipe fitting end. The grinder 702 is activated, which can drive the grinding wheel 703 to rotate at high speed, and can use the abrasive on the surface of the grinding wheel 703 to cut and grind the burrs at the pipe fitting end. During this process, the first motor 301 can drive the support box 4 to rotate as needed, driving the pipe fitting to rotate, so that the grinding wheel 703 can evenly grind the entire circumference of the pipe fitting end, ensuring that the burrs at all parts of the pipe fitting end can be effectively removed, and finally obtaining a smooth and flat end surface, which meets the processing accuracy and quality requirements of automotive pipe fittings.
