Technical Field
[0001] This utility model belongs to the field of alloy ball tooth machining technology, specifically relating to a surface treatment device used for alloy ball tooth machining. Background Technology
[0002] Carbide ball teeth, with their unique properties, are widely used in oilfield drilling and snow removal, snowplows or other equipment.
[0003] Depending on the type of oilfield drilling machinery, such as roller cone bits, down-the-hole bits, and geological drilling tools, carbide ball teeth are divided into different standard styles: P-type flat top, Z-type coin ball, and X-type wedge.
[0004] Stability and advanced technology guarantee the high quality of our products. Carbide ball teeth are frequently used as drilling tools for coal mining machines, mining machinery tools, and road maintenance tools for snow removal and road cleaning.
[0005] Carbide mining ball teeth are also widely used as excavation tools in quarrying, mining, tunneling, and civil construction. Furthermore, they are used as drill bit accessories in heavy-duty rock drills and deep-hole drill bit components.
[0006] The machining process of alloy ball teeth involves steps such as raw material preparation, powder processing, sintering, machining, coating, and quality inspection. The machining process includes various treatment methods, among which the surface treatment device is a surface treatment technology for the alloy ball teeth surface. Surface treatment technology includes various methods, one of which is grinding. However, existing surface treatment grinding equipment has poor workpiece fixation effect during use, mostly relying on bidirectional fixation, which has poor fixation stability, and it is not convenient to quickly adjust the grinding head during the grinding process. Therefore, we propose a surface treatment device for alloy ball teeth machining. Utility Model Content
[0007] The purpose of this utility model is to provide a surface treatment device for machining alloy ball teeth, so as to solve the problems mentioned in the background art that the existing surface treatment grinding equipment has poor workpiece fixation effect during use, mostly relies on bidirectional fixation, has poor fixation stability, and is not convenient for quick adjustment of the grinding head during the grinding process.
[0008] To achieve the above objectives, this utility model provides the following technical solution: a surface treatment device for machining alloy ball teeth, comprising a base, a fixed motor fixedly installed inside the base, a disc fixedly installed at the end of the output shaft of the fixed motor, a plurality of inclined slide tracks on the disc, and rollers rotatably installed within the inclined slide tracks, a plurality of straight slide tracks on the upper surface of the base, and sliding blocks slidably installed within the straight slide tracks, rollers rotatably installed on the lower surface of the sliding blocks, a fixed ejector pin fixedly installed on the upper surface of the sliding blocks, a support plate fixedly installed on the side of the base, a lifting motor fixedly installed on the surface of the support plate, and a threaded rod rotatably installed inside the support plate, the output of the lifting motor... A shaft is fixedly connected to a threaded rod. A threaded plate is threaded onto the outer surface of the threaded rod. A support plate is fixedly mounted on the side of the threaded plate. A cylinder is fixedly mounted on the surface of the support plate. An upper mounting plate is fixedly mounted on the end of the piston rod of the cylinder. The upper mounting plate is movably disposed inside a sliding hole on the support plate. A rotating shaft is rotatably mounted on the upper mounting plate. A rotating handle and a lower mounting plate are fixedly mounted on the top and bottom ends of the rotating shaft, respectively. Two side mounting plates are fixedly mounted on the lower surface of the lower mounting plate. A rotating shaft is rotatably mounted between the two side mounting plates. A mounting seat is fixedly mounted on the outer surface of the rotating shaft. A grinding motor is fixedly mounted on the lower surface of the mounting seat. A grinding head is mounted on the output shaft of the grinding motor.
[0009] The above scheme uses a disc in conjunction with rollers, sliding blocks, and fixed ejector pins. The rotation of the disc, along with the rollers, drives the four sliding blocks to move synchronously inward or outward. This, in turn, utilizes the four fixed ejector pins to achieve four-way positioning of the workpiece, improving the stability of the fixing effect, preventing shaking, and ensuring good accuracy in subsequent ball tooth surface machining. By using two rotating shafts, shaft one allows for horizontal rotation adjustment of the grinding head, while shaft two allows for angle adjustment of the grinding head, enabling grinding operations at various positions and angles and enhancing the versatility of the functions.
[0010] In the above scheme, it should be noted that the fixed motor, lifting motor, cylinder, and grinding motor are all electrically connected to an external power supply.
[0011] In a preferred embodiment, two limiting wheels are installed on the outer surface of the roller, and the two limiting wheels are respectively attached to the upper and lower surfaces of the disc.
[0012] By adopting the above solution, by setting a limiting wheel, which is attached to the surface of the disc, a rotational support effect can be achieved between the disc and the roller, ensuring the smooth movement of the disc and preventing tilting or wobbling.
[0013] In a preferred embodiment, a guide rod is fixedly installed on the inner wall of the straight slide rail on the base, and the sliding block is slidably installed on the outer surface of the guide rod.
[0014] By adopting the above scheme, the guide rod is used to support and guide the sliding block, preventing the sliding block from shaking, thereby ensuring the smooth movement of the fixed pin.
[0015] In a preferred embodiment, a guide bar is fixedly installed on the inner wall of the support plate, and a guide groove is provided on the side of the threaded plate, with the guide bar slidably installed on the inner wall of the guide groove.
[0016] With the above solution, when the threaded rod rotates and drives the threaded plate to move up and down, the threaded plate will slide on the surface of the guide bar through the guide groove. In this way, the cooperation between the guide bar and the guide groove can ensure the stability of the up and down movement of the threaded plate and prevent wobbling.
[0017] In a preferred embodiment, a plurality of guide rods are fixedly installed on the inner wall of the sliding hole on the support plate, and the upper mounting plate is slidably installed on the outer surface of the plurality of guide rods.
[0018] Using the above scheme, when the cylinder extends and retracts to drive the upper mounting plate to move horizontally, the upper mounting plate will slide stably on the surface of the second guide rod. Therefore, the setting of the second guide rod can ensure the stable horizontal movement of the upper mounting plate.
[0019] In a preferred embodiment, an adjusting locking rod is slidably mounted on the handle, an adjusting disc is fixedly mounted on the top of the adjusting locking rod, a spring is fixedly mounted between the adjusting disc and the handle, and a plurality of adjusting locking slots are provided on the upper mounting plate, with the adjusting locking rod and the adjusting locking slots used in conjunction.
[0020] By adopting the above scheme, the adjusting locking rod and spring are used in conjunction. When the adjusting locking rod slides out of the adjusting locking groove, the spring deforms, and at this time the handle is unlocked and can be rotated horizontally through the rotating shaft. Then, the mounting base is driven by the lower mounting plate and the side mounting plate to drive the grinding motor to rotate horizontally for adjustment. At the same time, after adjustment, the elastic force of the spring is used to drive the adjusting locking rod to move quickly and insert into the adjusting locking groove, which improves the convenience of locking operation.
[0021] In a preferred embodiment, a locking rod is fixedly installed on the side of the mounting base, and an arc-shaped slide is provided on the side of the side mounting plate. The locking rod passes through the arc-shaped slide, and the surface of the locking rod has threads and a locking nut is threadedly installed. The locking nut is fitted and arranged on the side of the side mounting plate.
[0022] Using the above solution, a locking rod is used in conjunction with a locking nut. When the locking nut is unscrewed, the mounting base is unlocked and can be rotated via the second rotating shaft, which in turn drives the grinding motor to rotate, thereby adjusting the angle position of the grinding head. After adjustment, the position is locked using the locking rod and locking nut. The locking structure is simple and easy to operate.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] The surface treatment equipment used for machining alloy ball teeth uses a disc in conjunction with rollers, sliding blocks, and fixed ejector pins. The rotation of the disc, together with the rollers, drives the four sliding blocks to move inward or outward synchronously. Then, the four fixed ejector pins are used to achieve four-way positioning of the workpiece, improve the stability of the fixing effect, avoid the phenomenon of fixing wobbling, and ensure good accuracy of subsequent ball tooth surface machining operations.
[0025] The surface treatment equipment used for machining alloy ball teeth uses two rotating shafts in combination. The first rotating shaft is used to adjust the horizontal position of the grinding head, and the second rotating shaft is used to adjust the angle of the grinding head, thus enabling grinding operations at various positions and angles and improving the versatility of functions.

A grinding head 21 is installed on the output shaft of the grinding motor 20.
[0035] By setting up a disc 3 in conjunction with rollers 4, sliding blocks 5, and fixed ejector pins 6, the rotation of the disc 3, in conjunction with the rollers 4, drives the four sliding blocks 5 to move synchronously inward or outward. This, in turn, utilizes the four fixed ejector pins 6 to achieve four-way positioning of the workpiece, improving the stability of the fixing effect, avoiding fixing wobbling, and ensuring good accuracy in subsequent ball tooth surface machining operations. By setting up rotating shaft one 14 and rotating shaft two 18 in conjunction, rotating shaft one 14 is used to adjust the horizontal position of the grinding head 21, and rotating shaft two 18 is used to adjust the angle of the grinding head 21, realizing grinding operations at various positions and angles, and improving the versatility of functions.
[0036] Two limiting wheels 22 are installed on the outer surface of the roller 4. The two limiting wheels 22 are respectively attached to the upper and lower surfaces of the disc 3. By setting the limiting wheels 22 and using the limiting wheels 22 attached to the surface of the disc 3, a rotational support effect can be achieved between the disc 3 and the roller 4, ensuring that the movement of the disc 3 is stable and not prone to tilting or shaking.
[0037] A guide rod 23 is fixedly installed on the inner wall of the straight slide on the base 1. The sliding block 5 is slidably installed on the outer surface of the guide rod 23.

[0038] A guide bar 24 is fixedly installed on the inner wall of the support plate 7. A guide groove is provided on the side of the threaded plate 10. The guide bar 24 is slidably installed on the inner wall of the guide groove. When the threaded rod 9 rotates to drive the threaded plate 10 to move up and down, the threaded plate 10 will slide on the surface of the guide bar 24 through the guide groove. The guide bar 24 and the guide groove cooperate to ensure the stability of the up and down movement of the threaded plate 10 and prevent wobbling.
[0039] Several guide rods 25 are fixedly installed on the inner wall of the sliding hole on the support plate 11. The upper mounting plate 13 is slidably installed on the outer surface of the several guide rods 25. When the cylinder 12 extends and retracts to drive the upper mounting plate 13 to move horizontally, the upper mounting plate 13 will slide stably on the surface of the guide rods 25. Therefore, the setting of the guide rods 25 can ensure the stable horizontal movement of the upper mounting plate 13.
[0040] An adjusting locking rod 26 is slidably mounted on the handle 15. An adjusting disc 27 is fixedly mounted on the top of the adjusting locking rod 26. A spring 28 is fixedly mounted between the adjusting disc 27 and the handle 15. Several adjusting locking slots are provided on the upper mounting plate 13. The adjusting locking rod 26 and the adjusting locking slots work together. By setting the adjusting locking rod 26 and the spring 28 to work together, when the adjusting locking rod 26 slides out of the adjusting locking slot, the spring 28 deforms. At this time, the handle 15 is unlocked and can be rotated horizontally through the rotating shaft 14. Then, the mounting base 19 is driven by the lower mounting plate 16 and the side mounting plate 17 to drive the grinding motor 20 to rotate horizontally for adjustment. At the same time, after adjustment, the elastic force of the spring 28 drives the adjusting locking rod 26 to move quickly and insert into the adjusting locking slot, improving the convenience of locking operation.
[0041] A locking rod 29 is fixedly installed on the side of the mounting base 19. An arc-shaped slide is provided on the side of the side mounting plate 17. The locking rod 29 passes through the arc-shaped slide. The surface of the locking rod 29 has threads and a locking nut 30 is installed on the threads. The locking nut 30 is fitted against the side of the side mounting plate 17. The locking rod 29 is used in conjunction with the locking nut 30. When the locking nut 30 is unscrewed, the mounting base 19 is unlocked and can be rotated by the rotating shaft 18, which in turn drives the grinding motor 20 to rotate, thereby adjusting the angle position of the grinding head 21. After adjustment, the position is locked by the locking rod 29 and the locking nut 30. The locking structure is simple and easy to operate.
[0042] In use, place the ball-tooth workpiece to be ground on the surface of the base 1, start the fixed motor 2, and the fixed motor 2 drives the disc 3 to rotate. The cooperation of the inclined slide and roller 4, and the cooperation of the straight slide and sliding block 5, drives the four fixed ejector pins 6 to move inward synchronously, thus fixing the workpiece. After fixing, stop the fixed motor 2. Adjust the angle of the grinding head 21 according to the grinding operation requirements. During adjustment, unscrew the locking nut 30. At this time, the mounting base 19 is unlocked and can rotate through the rotating shaft 18, thereby driving the grinding motor 20 to rotate, achieving the adjustment of the angle tilt position of the grinding head 21 on the grinding motor 20. After adjustment, tighten the locking nut 30 to lock the position. Then, adjust the grinding head 21 according to the grinding operation requirements. The grinding head 21 is rotated for adjustment. During adjustment, the adjustment plate is pulled, and the adjustment plate drives the adjustment locking rod 26 to move away from the adjustment locking groove. At this time, the spring 28 deforms and the handle 15 is unlocked. The handle 15 drives the rotating shaft 14 to drive the lower mounting plate 16 to rotate. Then, the side mounting plate 17 and the mounting base 19 drive the grinding motor 20 to rotate horizontally. After the position is adjusted, the adjustment plate is released. The elastic force of the spring 28 drives the adjustment locking rod 26 to insert into the adjustment locking groove. Then, the cylinder 12 is started to drive the upper mounting plate 13 to move horizontally, adjusting the horizontal position of the grinding head 21. Then, the lifting motor 8 drives the threaded rod 9 to rotate, which in turn drives the threaded plate 10 to drive the support plate 11 to move up and down, which in turn drives the grinding head 21 to move up and down to achieve surface grinding operation.
