Description

TECHNICAL FIELD

[0002] Vehicle engine gears are key components in the power transmission system of a vehicle. They are mainly responsible for distributing and transmitting the rotational power output by the engine to other components of the vehicle, such as the transmission, transfer case, and differential. Vehicle engine gears can be divided into various types, each with specific functions and roles. Gears are typically made of high-quality carbon steel, alloy steel, or ductile cast iron, which have good strength and wear resistance, capable of withstanding high loads and high-speed rotation during engine operation. The design and manufacturing of gears require high precision to ensure smooth transmission, high efficiency, and low noise.

[0003] During the production process, vehicle engine gears may have slight dimensional deviations or surface irregularities, which need to be polished by a vehicle engine gear polishing device. Polishing can eliminate these errors, making the gear teeth more precise, improving the precision of gear meshing, reducing noise and vibration during transmission, making the gear surface smoother, reducing friction resistance, and improving energy transmission efficiency. The vehicle engine gear polishing device in the prior art is a device used for polishing gears inside a vehicle engine. It can effectively remove burrs, rust, and wear layers on the gear surface, improving the working performance and service life of the gear.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see Figures 1-5 This invention provides a technical solution: a vehicle engine gear grinding device, including a frame 1, a grinding wheel positioning assembly 2 fixedly mounted on the top of the frame 1, an angle adjustment mechanism 3 fixedly mounted on the top of the grinding wheel positioning assembly 2, a drive mechanism 4 fixedly mounted on one side of the angle adjustment mechanism 3, a grinding wheel mechanism 5 fixedly mounted on one side of the drive mechanism 4, a turntable 6 fixedly mounted on the top of the frame 1, a locking mechanism 8 provided inside the turntable 6, a quick-connect mechanism 7 provided on the top of the locking mechanism 8, and a fixed core movably mounted on the top of the turntable 6. The gear 10 to be ground is fixedly installed on the top of the turntable 6 via a quick-connect mechanism 7, a locking mechanism 8, and a fixed spindle 9. The locking mechanism 8 includes a locking sleeve 801, which is slidably installed inside the turntable 6. A locking groove 802 is provided inside the locking sleeve 801. A pressure switch 803 is fixedly installed inside the locking sleeve 801. A tension spring 804 is fixedly installed at the bottom of the locking sleeve 801. The tension spring 804 is fixedly installed inside the turntable 6. A telescopic component 805 is fixedly installed inside the turntable 6.

[0034] The quick-connect mechanism 7 includes a mounting sleeve 701, a plurality of locking balls 702 are movably mounted inside the mounting sleeve 701, a pressing rod 703 is slidably mounted inside the mounting sleeve 701, an unlocking groove 704 is provided on the outer wall of the pressing rod 703, and a fixing piece 705 is fixedly mounted on the top of the mounting sleeve 701.

[0035] A quick-lock sleeve 706 is fixedly installed on the top of the fixing plate 705. Several sliding grooves 707 are opened on the outer wall of the quick-lock sleeve 706. A locking area 708 is provided on one side of the sliding groove 707. A quick-lock post 710 is fixedly installed on the top of the pressing rod 703. Several quick-lock blocks 711 are fixedly installed on the outer wall of the quick-lock post 710. The quick-lock blocks 711 are movably installed inside the sliding groove 707. An anti-detachment spring 709 is fixedly installed inside the quick-lock sleeve 706. The anti-detachment spring 709 is located at the bottom of the mounting sleeve 701. An anti-slip torsion 712 is fixedly installed on the top of the quick-lock post 710.

[0036] Several positioning columns 12 are fixedly installed on the top of the turntable 6, and several positioning grooves 13 are opened at the bottom of the fixed spindle 9.

[0037] Several shock-absorbing supports 11 are fixedly installed at the bottom of the frame 1.

[0038] The specific implementation method is as follows: The fixed mandrel 9 is accurately installed on the surface of the turntable 6 through the cooperation of the positioning pin 12 and the positioning groove 13. The gear to be ground 10 is then fitted onto the outer wall of the fixed mandrel 9. The telescopic assembly 805 is activated to lift the locking sleeve 801 to the top of the turntable 6. The quick-connect mechanism 7 is inserted through the fixed mandrel 9 into the interior of the turntable 6. After the turntable 6 reaches the interior of the locking mechanism 8, the anti-slip knob 712 is pressed to displace the pressing rod 703 downwards. During this process… The pressing rod 703 presses several locking balls 702 into the locking groove 802, locking the quick-connect mechanism 7 inside the locking mechanism 8. Then, the anti-slip knob 712 is pressed to move the quick-lock block 711 to the bottom of the slide groove 707. The anti-slip knob 712 is rotated to move the quick-lock block 711 to the bottom of the locking area 708. When released, the anti-disengagement spring 709 presses the quick-lock block 711 to the top of the locking area 708, fixing the pressing rod 703 to the mounting sleeve 70. Inside 1, during this process, after the extrusion rod 703 moves to the locking position, its bottom will press the pressure switch 803. The pressure switch 803 closes the telescopic component 805, causing the telescopic component 805 to retract. At this time, the locking sleeve 801 loses the support of the telescopic component 805 and will be pulled by the tension spring 804 to move the quick insertion mechanism 7 to the bottom of the turntable 6, thereby driving the fixing plate 705 to move downward, pressing and fixing the fixing mandrel 9 and the gear 10 to be ground to the top of the turntable 6. When the fixing mandrel 9 needs to be replaced, the above process can be reversed. In summary, this equipment can quickly replace the fixing mandrel 9 of different specifications through the cooperation of the quick insertion mechanism 7 and the locking mechanism 8. Because the quick insertion mechanism 7 is tightened and fixed to the top of the fixing mandrel 9 and the gear 10 to be ground by the locking mechanism 8, the cooperation of the quick insertion mechanism 7 and the locking mechanism 8 can also adapt to the fixing mandrel 9 and the gear 10 to be ground of different heights, and has the advantage of quickly adapting to gears of different sizes or types.

[0039] Then, the position of the grinding wheel mechanism 5 in three-dimensional space is adjusted by the grinding wheel positioning component 2, so that the grinding wheel mechanism 5 meshes with the gear 10 to be ground. The drive mechanism 4 and the turntable 6 are started to drive the grinding wheel mechanism 5 and the gear 10 to be ground to rotate, and the gear 10 to be ground is ground. During this process, the angle adjustment mechanism 3 can adjust the tilt angle of the grinding wheel mechanism 5, so that the grinding wheel mechanism 5 can mesh with helical gears with different tilt angles for grinding. The vibration damping support 11 reduces unnecessary vibration, making the grinding process more stable and helping to improve the surface finish and size of the gear.

[0040] Please see Figures 1-6The present invention provides a technical solution: a vehicle engine gear grinding device, wherein the angle adjustment mechanism 3 includes a support frame 301, the support frame 301 is fixedly installed on the top of the grinding wheel positioning assembly 2, a bidirectional screw 302 is rotatably installed on one side of the support frame 301, two sets of displacement blocks 303 are threadedly connected to the outer wall of the bidirectional screw 302, a connecting rod 304 is rotatably installed on one side of the displacement block 303, a turntable 305 is rotatably installed on one side of the support frame 301, the turntable 305 is fixedly connected to one side of the drive mechanism 4, and the connecting rod 304 is rotatably installed on one side of the turntable 305;

[0041] An adjusting motor 307 is fixedly installed on one side of the support frame 301. The output shaft of the adjusting motor 307 is fixedly connected to one side of the bidirectional screw 302 via a coupling. Two sets of limiting rods 306 are fixedly installed on one side of the support frame 301. The displacement block 303 is slidably installed on the outer wall of the limiting rod 306.

[0042] The specific implementation method is as follows: by adjusting the motor 307 to drive the bidirectional screw 302 to rotate, the two sets of displacement blocks 303 are moved towards the center or both ends of the bidirectional screw 302. When the displacement blocks 303 are moved, the connecting rod 304 drives the turntable 305 to rotate, thereby changing the angle of the drive mechanism 4 through the turntable 305, and thus changing the tilt angle of the grinding wheel mechanism 5. During this process, the displacement of the displacement blocks 303 is made more stable by the two sets of limit rods 306.

[0043] Please see Figures 1-8 The present invention provides a technical solution: a vehicle engine gear grinding device, wherein the drive mechanism 4 includes a mounting bracket 401, a drive motor 402 is fixedly mounted on one side of the mounting bracket 401, the drive motor 402 is fixedly connected to one side of the grinding wheel mechanism 5 through a coupling, and a waterproof cover 403 is rotatably mounted on one side of the mounting bracket 401, the waterproof cover 403 is disposed on the top of the drive motor 402.

[0044] A mounting rod 405 is fixedly mounted on the top of the mounting bracket 401. The mounting rod 405 is set on the top of the grinding wheel mechanism 5. A liquid supply nozzle 406 is fixedly mounted on one end of the mounting rod 405, and a cleaning nozzle 407 is fixedly mounted on the bottom of the mounting rod 405. The nozzle directions of both the liquid supply nozzle 406 and the cleaning nozzle 407 are tangent to the grinding wheel mechanism 5.

[0045] The grinding wheel mechanism 5 includes a grinding roller 501. A coarse grinding tooth 502 is fixedly installed on the outer wall of the grinding roller 501. A fine grinding tooth 503 is provided on one side of the coarse grinding tooth 502. A polishing grinding tooth 504 is fixedly installed on one side of the fine grinding tooth 503.

[0046] The specific implementation method is as follows: The grinding wheel mechanism 5 is driven to rotate by the drive motor 402 to grind the gear 10 to be ground. During this process, the grinding fluid is sprayed onto the surface of the grinding wheel mechanism 5 through the liquid supply nozzle 406 to cool and lubricate the grinding wheel mechanism 5, reduce the wear of the grinding wheel mechanism 5, and extend its service life. The cleaning fluid is sprayed through the cleaning nozzle 407 to clean the metal shavings, oil stains and other impurities attached to the surface of the grinding wheel mechanism 5, restore its original grinding ability and surface roughness, and ensure the grinding quality. The drive motor 402 is protected by the waterproof cover 403 to prevent the grinding fluid and cleaning fluid from splashing into the interior of the drive motor 402 and damaging the drive motor 402. The handle 404 makes it convenient for the staff to open and close the waterproof cover 403 to maintain the drive motor 402.

[0047] The gear 10 to be ground is coarsely ground by the coarse grinding teeth 502, and then the position is adjusted by the grinding wheel positioning assembly 2 so that the fine grinding teeth 503 contact the outer wall of the gear 10 to be ground for fine grinding. Then the position is adjusted by the grinding wheel positioning assembly 2 so that the polishing grinding teeth 504 contact the outer wall of the gear 10 to be ground for polishing. By integrating different processing stages on the same grinding roller 501, the coarse grinding, fine grinding and polishing processes can be completed continuously without changing tools or adjusting the workpiece, which greatly improves processing efficiency.

[0048] Working principle: When using this vehicle engine gear grinding device, the fixed mandrel 9 is accurately installed on the surface of the turntable 6 through the cooperation of the positioning pin 12 and the positioning groove 13. Then, the gear to be ground 10 is sleeved and installed on the outer wall of the fixed mandrel 9. The telescopic component 805 is activated to lift the locking sleeve 801 to the top of the turntable 6. The quick-connect mechanism 7 is inserted through the fixed mandrel 9 into the interior of the turntable 6. After the turntable 6 reaches the interior of the locking mechanism 8, the anti-slip knob 712 is pressed to compress the pressing rod 70. 3. The device moves downwards. During this process, the pressing rod 703 presses several locking balls 702 into the locking groove 802, locking the quick-connect mechanism 7 inside the locking mechanism 8. Then, the anti-slip knob 712 is pressed to move the quick-lock block 711 to the bottom of the slide groove 707. The anti-slip knob 712 is rotated to move the quick-lock block 711 to the bottom of the locking area 708. When released, the anti-disengagement spring 709 presses the quick-lock block 711 to the top of the locking area 708, securing the pressing rod 703. The device is fixed inside the mounting sleeve 701. During this process, the pressing rod 703 moves to the locking position and then presses the pressure switch 803 at the bottom. The pressure switch 803 closes the telescopic component 805, causing the telescopic component 805 to retract. At this time, the locking sleeve 801 loses the support of the telescopic component 805 and will be pulled by the tension spring 804 to move the quick insertion mechanism 7 to the bottom of the turntable 6. This will cause the fixing plate 705 to move downward, pressing and fixing the fixing mandrel 9 and the gear 10 to be ground to the top of the turntable 6. When the fixing mandrel 9 needs to be replaced, the above process can be reversed. In summary, this device can quickly replace the fixing mandrel 9 of different specifications through the cooperation of the quick insertion mechanism 7 and the locking mechanism 8. Because the quick insertion mechanism 7 is tightened and fixed to the top of the fixing mandrel 9 and the gear 10 to be ground by the locking mechanism 8, the cooperation of the quick insertion mechanism 7 and the locking mechanism 8 can also adapt to the fixing mandrel 9 and the gear 10 to be ground of different heights, and has the advantage of quickly adapting to gears of different sizes or types.

[0049] Then, the position of the grinding wheel mechanism 5 in three-dimensional space is adjusted by the grinding wheel positioning component 2 so that the grinding wheel mechanism 5 meshes with the gear 10 to be ground. The drive mechanism 4 and the turntable 6 are started to drive the grinding wheel mechanism 5 and the gear 10 to be ground to rotate and grind the gear 10. During this process, the angle adjustment mechanism 3 can adjust the tilt angle of the grinding wheel mechanism 5 so that the grinding wheel mechanism 5 can mesh with helical gears with different tilt angles for grinding. The vibration damping support 11 reduces unnecessary vibration, making the grinding process more stable and helping to improve the surface finish and size of the gear.

[0050] By adjusting the motor 307 to drive the bidirectional screw 302 to rotate, the two sets of displacement blocks 303 are moved toward the center or both ends of the bidirectional screw 302. When the displacement blocks 303 are moved, the connecting rod 304 drives the turntable 305 to rotate, thereby changing the angle of the drive mechanism 4 through the turntable 305, and thus changing the tilt angle of the grinding wheel mechanism 5. During this process, the displacement of the displacement blocks 303 is made more stable by the two sets of limit rods 306.

[0051] The grinding wheel mechanism 5 is driven by the drive motor 402 to rotate and grind the gear 10 to be ground. During this process, the grinding fluid is sprayed onto the surface of the grinding wheel mechanism 5 through the liquid supply nozzle 406 to cool and lubricate the grinding wheel mechanism 5, reduce the wear of the grinding wheel mechanism 5, and extend its service life. The cleaning fluid is sprayed through the cleaning nozzle 407 to clean the metal shavings, oil and other impurities attached to the surface of the grinding wheel mechanism 5, restore its original grinding ability and surface roughness, and ensure the grinding quality. The drive motor 402 is protected by the waterproof cover 403 to prevent the grinding fluid and cleaning fluid from splashing into the drive motor 402 and damaging the drive motor 402. The handle 404 makes it easy for the staff to open and close the waterproof cover 403 to maintain the drive motor 402.

[0052] The gear 10 to be ground is coarsely ground by the coarse grinding teeth 502, and then the position is adjusted by the grinding wheel positioning assembly 2 so that the fine grinding teeth 503 contact the outer wall of the gear 10 to be ground for fine grinding. Then the position is adjusted by the grinding wheel positioning assembly 2 so that the polishing grinding teeth 504 contact the outer wall of the gear 10 to be ground for polishing. By integrating different processing stages on the same grinding roller 501, the coarse grinding, fine grinding and polishing processes can be completed continuously without changing tools or adjusting the workpiece, which greatly improves processing efficiency.

[0053] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
