Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of tire grinding machines, specifically a tire grinding device. Background Technology
[0002] Rubber tires are tires made of rubber. Because rubber tires are relatively soft, they have strong shock absorption capabilities, which can prevent damage to the internal parts of a car. In addition, rubber tires are very durable and inexpensive, making them very convenient to use.
[0003] The specific design and structure of automatic unloading devices for hot forging production may vary depending on the manufacturer and application requirements, but generally they include the following key components: frame, tire fixing device, and grinding disc, etc. The frame is usually made of sturdy metal materials such as channel steel and angle steel, welded or bolted together, and is the foundation of the entire device, used to support and fix other components. The tire fixing device commonly includes chucks, clamps, etc., which use mechanical structures or hydraulic devices to firmly fix the tire in the designated position, ensuring that the tire does not shake or shift during the grinding process. The grinding disc is the component that directly grinds the tire, and is usually made of wear-resistant materials such as diamond or silicon carbide. It has different shapes and sizes depending on the grinding area and requirements.
[0004] In traditional tire grinding, if the tire is not securely fixed, it is prone to shaking or displacement under high-speed rotation. This not only leads to uneven grinding, affecting grinding accuracy and quality, but may also cause abnormal collisions between the grinding tools and the tire, damaging the equipment and the tire, and even causing safety accidents. Different tire sizes vary, and if the device can only accommodate a single size tire, the company will need to equip itself with multiple fixing devices for different tire sizes, which undoubtedly increases the company's equipment procurement costs and management difficulty. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and address the problems of existing equipment, this utility model proposes a tire grinding device.
[0006] The technical solution adopted by this utility model to solve its technical problem is a tire grinding device, including a base, a mounting plate on the base, a first motor bracket on the mounting plate, a grinding motor mounted on the first motor bracket, a fixed plate at the output end of the grinding motor, a fixed transmission wheel rotatably mounted inside the fixed plate, a fixed button at the top of the fixed transmission wheel and located outside the fixed plate, and two positioning plates with sliding holes symmetrically arranged inside the fixed plate, with racks symmetrically sliding in the sliding holes on the two positioning plates, the two racks being positioned above and below the fixed transmission wheel. On both sides, and meshing with a fixed transmission wheel, the fixed plate is provided with a sliding hole, and the tops of the two racks are respectively provided with an arc-shaped fixed plate through one of the sliding holes; a second motor bracket is provided on the mounting plate. A transmission motor is mounted on the second motor bracket, and an adjusting transmission wheel is provided at the output end of the transmission motor. Two sliding grooves are opened on the mounting plate, and adjusting plates are provided on both sides of the two sliding grooves. A transmission screw and a positioning rod are rotatably provided between the two sets of adjusting plates, and the tops of the two transmission screws are provided with driven wheels through the adjusting plates, and the two driven wheels are meshed with the adjusting transmission wheel.
[0007] Preferably, each of the two grooves has a mounting block slidably disposed therein. Each mounting block has a threaded hole and a positioning hole. Two drive screws rotate through the threaded holes on one mounting block, and two positioning rods pass through the positioning holes on one mounting block. Both mounting blocks are equipped with grinding rods. A drive motor drives an adjusting drive wheel, which in turn rotates the drive screws via the driven wheel, thereby driving the mounting blocks to move within the grooves. Because the two drive screws are in opposite directions, the two mounting blocks can move linearly towards or away from each other. The position of the grinding rods can be precisely adjusted. Operators can flexibly adjust the contact position and distance between the grinding rods and the tire according to the specific grinding requirements of the tire, ensuring that the grinding effect meets the process requirements.
[0008] Preferably, the base is equipped with a slag discharge bucket, a hinged sealing door is provided on the slag discharge bucket, and a switch handle is provided on the sealing door. A dust collection pipe is provided at the top of the slag discharge bucket, and a dust collection bag is provided behind the dust collection pipe. The dust collection bag can be replaced through the sealing door. An activated carbon plate is provided behind the dust collection bag, and a dust suction fan is provided behind the activated carbon plate. A No. 3 motor bracket is provided behind the dust suction fan, and a dust removal motor is installed on the No. 3 motor bracket. The output end of the dust removal motor is fixedly connected to the dust suction fan. An exhaust pipe is provided at the bottom of the slag discharge bucket. The dust collection bag can intercept larger dust particles, and the activated carbon plate can absorb odors and fine particles. The filtered and purified air is discharged through the exhaust pipe, reducing dust pollution to the working environment, protecting the health of operators, and meeting environmental protection requirements.
[0009] Preferably, a dust collection box is provided below the fixed plate, and the other end of the dust collection pipe is connected to the dust collection box. The dust collection box is located below the fixed plate and can directly collect the dust falling from the tire grinding area. Because it is close to the grinding position, it can collect the dust generated during the grinding process to the maximum extent, avoid the dust from spreading around the equipment, keep the working environment clean, reduce the pollution of other parts of the equipment by dust, and reduce the risk of equipment failure due to dust accumulation.
[0010] Preferably, the two drive screws are in the same direction, and inclined support plates are symmetrically fixed on both sides of the bottom of the mounting plate. When the drive motor drives the adjusting rotating wheel to rotate, the two driven wheels drive the two drive screws to rotate in opposite directions. The inclined support plates symmetrically installed on both sides of the bottom of the mounting plate enhance the stability of the mounting plate, can withstand the vibration and impact generated during the grinding process, ensure the stability of the overall structure of the equipment, and extend the service life of the equipment.
[0011] Preferably, the grinding motor, drive motor, and dust removal motor are all electrically connected to an external power source. The external power source can provide continuous and stable power to each motor, ensuring continuous and stable operation of the equipment, improving the efficiency and quality of tire grinding, and avoiding work interruptions caused by insufficient power.
[0012] The advantages of this invention are as follows: by rotating the fixing knob to drive the fixed transmission wheel to rotate, and using gear and rack transmission to move the two arc-shaped fixing plates towards each other to fix the tire, this method can provide a large clamping force, ensuring that the tire remains stable during high-speed rotating grinding without shaking or displacement, thus guaranteeing the precision and quality of grinding. The relative position of the arc-shaped fixing plates can be adjusted according to the size of the tire, which can adapt to tires of different sizes, improving the versatility and applicability of the equipment, and reducing the cost for enterprises to equip multiple fixing devices for different specifications of tires.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 scope of protection of the present utility model.
[0021] Please see Figure 1-5 As shown, a tire grinding device includes a base 1, a mounting plate 2 on the base 1, a first motor bracket 3 on the mounting plate 2, a grinding motor 4 mounted on the first motor bracket 3, a fixed plate 5 at the output end of the grinding motor 4, a fixed transmission wheel 6 rotatably mounted inside the fixed plate 5, a fixed button 10 at the top of the fixed transmission wheel 6 and located outside the fixed plate 5, two positioning plates 7 with sliding holes symmetrically arranged inside the fixed plate 5, racks 8 symmetrically slidably arranged in the sliding holes on the two positioning plates 7, the two racks 8 are located on the upper and lower sides of the fixed transmission wheel 6 and mesh with the fixed transmission wheel 6 for transmission, the fixed plate 5 is provided with sliding holes, and the tops of the two racks 8 are respectively provided with arc-shaped fixed plates 11 passing through a sliding hole;
[0022] During operation, in order to secure the tire, the operator places the tire to be ground on the fixed plate 5 and rotates the fixing button 10 outside the fixed plate 5. The fixing button 10 drives the fixed transmission wheel 6 inside the fixed plate 5 to rotate. Since the two racks 8 are located on the upper and lower sides of the fixed transmission wheel 6 respectively and mesh with it, and the racks 8 slide in the sliding hole of the positioning plate 7, the two racks 8 move in opposite directions in a straight line. The opposite linear movement of the racks 8 drives the two arc-shaped fixing plates 11 to move in opposite directions until the tire is firmly fixed on the fixed plate 5.
[0023] The mounting plate 2 is provided with a second motor bracket 12. A drive motor 13 is mounted on the second motor bracket 12. An adjusting drive wheel 14 is provided at the output end of the drive motor 13. Two sliding grooves 18 are provided on the mounting plate 2. Adjusting plates 9 are provided on both sides of the two sliding grooves 18. A drive screw 15 and a positioning rod 17 are rotatably arranged between the two sets of adjusting plates 9. The top ends of the two drive screws 15 pass through the adjusting plates 9 and are provided with driven wheels 16. The two driven wheels 16 are engaged with the adjusting drive wheel 14.
[0024] Each of the two slide grooves 18 has a mounting block 19 slidably disposed therein. Both mounting blocks 19 have threaded holes and positioning holes. The two transmission screws 15 rotate through the threaded holes on one of the mounting blocks 19, and the two positioning rods 17 pass through the positioning holes on one of the mounting blocks 19. Both mounting blocks 19 are provided with grinding rods 20.
[0025] During operation, to polish the tire, the drive motor 13 mounted on the second motor bracket 12 is started. The adjusting drive wheel 14 at the output end of the drive motor 13 rotates accordingly. The adjusting drive wheel 14 meshes with the driven wheel 16, driving the driven wheel 16 to rotate. The driven wheel 16 is mounted on the top of the drive screw 15, thereby causing the two drive screws 15 to rotate. Since the two drive screws 15 have the same thread direction but opposite rotation direction, according to the screw drive principle, the rotation of the drive screws 15 causes the two mounting blocks 19 to make linear movements in opposite directions within the slide groove 18. The movement of the mounting blocks 19 drives the polishing rod 20 to move to the appropriate position. Then, the polishing motor 4 mounted on the first motor bracket 3 is started. The output end of the polishing motor 4 drives the fixed plate 5 and the tire fixed on it to rotate. The rotating tire surface contacts the polishing rod 20 on the mounting block 19, and the polishing rod 20 polishes the tire to remove impurities and uneven parts from the tire surface.
[0026] A slag discharge bucket 22 is provided on the base 1. A sealing door 23 is hinged to the slag discharge bucket 22. A switch handle 24 is provided on the sealing door 23. A dust collection pipe 31 is provided at the top of the slag discharge bucket 22. A dust collection bag 25 is provided behind the dust collection pipe 31. The dust collection bag 25 can be replaced through the sealing door 23. An activated carbon plate 26 is provided behind the dust collection bag 25. A dust suction fan 27 is provided behind the activated carbon plate 26. A No. 3 motor bracket 28 is provided behind the dust suction fan 27. A dust removal motor 29 is installed on the No. 3 motor bracket 28. The output end of the dust removal motor 29 is fixedly connected to the dust suction fan 27. An exhaust pipe 30 is provided at the bottom of the slag discharge bucket 22.
[0027] A dust collection box 21 is provided below the fixed plate 5, and the other end of the dust collection pipe 31 is connected to the dust collection box 21. The two transmission screws 15 are in the same direction. When the transmission motor 13 drives the adjusting transmission wheel 14 to rotate, the two driven wheels 16 drive the two transmission screws 15 to rotate in opposite directions. The two sides of the bottom of the mounting plate 2 are symmetrically fixed with inclined support plates 32. The grinding motor 4, the transmission motor 13 and the dust removal motor 29 are all electrically connected to the external power supply.
[0028] During operation, in order to handle the dust generated during tire grinding, the dust removal motor 29, installed on the No. 3 motor bracket 28, is started during the grinding process. The output end of the dust removal motor 29 drives the dust suction fan 27 to rotate. The rotation of the dust suction fan 27 generates suction, creating a negative pressure in the dust collection box 21 below the fixed plate 5. The dust generated during tire grinding is sucked into the dust collection box 21. The dust enters the slag discharge bucket 22 through the dust collection pipe 31. The dust first undergoes preliminary filtration through the dust collection bag 25. Larger dust particles are intercepted in the dust collection bag 25. The air filtered by the dust collection bag 25 continues to pass through the activated carbon plate 26. The activated carbon plate 26 adsorbs odors and some small particles in the dust, further purifying the air. The filtered and purified air is discharged from the device through the exhaust pipe 30 at the bottom of the slag discharge bucket 22.
[0029] Working principle: In order to fix the tire, the operator places the tire to be ground on the fixed plate 5 and rotates the fixing button 10 outside the fixed plate 5. The fixing button 10 drives the fixed transmission wheel 6 inside the fixed plate 5 to rotate. Since the two racks 8 are located on the upper and lower sides of the fixed transmission wheel 6 and mesh with it, and the racks 8 slide in the sliding hole of the positioning plate 7, the two racks 8 move in opposite directions in a straight line. The opposite linear movement of the racks 8 drives the two arc-shaped fixing plates 11 to move in opposite directions until the tire is firmly fixed on the fixed plate 5.
[0030] To polish the tire, the drive motor 13 mounted on the second motor bracket 12 is started. The adjusting drive wheel 14 at the output end of the drive motor 13 rotates accordingly. The adjusting drive wheel 14 meshes with the driven wheel 16, driving the driven wheel 16 to rotate. The driven wheel 16 is mounted on the top of the drive screw 15, thereby causing the drive screw 15 to rotate. Since the two drive screws 15 have the same thread direction but opposite rotation direction, according to the screw drive principle, the rotation of the drive screw 15 causes the two mounting blocks 19 to move in opposite directions within the slide groove 18. The movement of the mounting blocks 19 drives the polishing rod 20 to move to the appropriate position. Then, the polishing motor 4 mounted on the first motor bracket 3 is started. The output end of the polishing motor 4 drives the fixed plate 5 and the tire fixed on it to rotate. The rotating tire surface contacts the polishing rod 20 on the mounting block 19, and the polishing rod 20 polishes the tire to remove impurities and uneven parts from the tire surface.
[0031] To handle the dust generated during tire grinding, the dust removal motor 29, mounted on the No. 3 motor bracket 28, is activated during the grinding process. The output of the dust removal motor 29 drives the dust extraction fan 27 to rotate, generating suction and creating negative pressure in the dust collection box 21 below the fixed plate 5. The dust generated during tire grinding is sucked into the dust collection box 21 and then enters the slag discharge bucket 22 through the dust collection pipe 31. The dust is first initially filtered by the dust collection bag 25, where larger dust particles are trapped. The air filtered by the dust collection bag 25 continues to pass through the activated carbon plate 26, which adsorbs odors and some fine particles from the dust, further purifying the air. The filtered and purified air is then discharged from the device through the exhaust pipe 30 at the bottom of the slag discharge bucket 22.
