Description

Technical Field

[0001] This utility model relates to the field of diamond wheel tooth cutting technology, specifically a high-precision diamond wheel tooth cutting device. Background Technology

[0002] A diamond wheel is a grinding or cutting tool made of diamond as an abrasive. It is widely used for processing hard and brittle materials. Diamond is the hardest material in nature, so diamond wheels have extremely high hardness, wear resistance and cutting efficiency, making them particularly suitable for processing high-hardness materials.

[0003] Because existing diamond wheels come in various sizes, conventional tooth-cutting devices typically use bolts or fixed shafts to secure them. This can cause gaps to form between the diamond wheel and the fixed shaft or bolts during tooth cutting, leading to wobbling and reduced tooth precision. Therefore, we provide a high-precision tooth-cutting device for diamond wheels. Utility Model Content

[0007] As a preferred technical solution of this utility model: the tooth-cutting assembly includes a second servo motor, a rotating shaft is fixedly sleeved on the outer edge of the power output shaft of the second servo motor, a second circular groove is formed on the inner wall of the rotating shaft, a third circular groove is formed on the outer wall of the rotating shaft, a sleeve is fixedly installed on the inner wall of the second circular groove, one end of a spring is fixedly connected to the inner wall of the sleeve, a ball is fixedly connected to the other end of the spring, a tooth-cutting cutter is provided on the outer wall of the rotating shaft, and a slot is formed on the inner wall of the tooth-cutting cutter.

[0008] As a preferred technical solution of this utility model: there are three sleeves, three springs and three balls, and each sleeve, spring and ball is a group, which is set in the inner cavity of the second circular groove. There are three third circular grooves and three slots, and the three third circular grooves and slots are arranged opposite to each other. The third circular groove is located in the inner wall of the third circular groove and is adapted to the slot. The diameter of the ball is larger than the diameter of the outer wall of the third circular groove.

[0009] As a preferred technical solution of this utility model: the inner wall of the circular groove is in contact with the inner wall of the placement plate, and the outer wall of the placement plate is rotatably arranged with respect to the inner wall of the circular groove.

[0010] As a preferred technical solution of this utility model: the number of the servo motor, worm gear, worm, threaded rod and slider are four, and each servo motor, worm gear, worm, threaded rod and slider is arranged as a group in the inner cavity of the placement plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This high-precision gear cutting device for diamond wheels places diamond wheel bodies of different sizes on the top of a placement plate. Then, by activating servo motor one, the outer edges of the power output shafts of the four servo motors one drive four worm gears to rotate. This causes the outer edges of the four worm gears to mesh and rotate with the outer edges of the four worms, which in turn drive the threaded rods to rotate. As the threaded rods rotate, they drive four sliders to move. These sliders then drive four trapezoidal blocks to move along the inner walls of the four grooves two towards the inner wall of the diamond wheel body, thus fixing the diamond wheel body in place. This achieves the fixation of diamond wheel bodies of different sizes, thereby reducing the phenomenon of inaccurate gear cutting of the diamond wheel body.

[0015] 2. This high-precision diamond wheel tooth-cutting device, by rotating the tooth-cutting cutter, causes three spheres that are adapted to the shape of the three slots to slide and disengage from the three slots. As the three spheres disengage from the inner wall of the slots, they drive three springs to move closer to the inner wall of the three sleeves. Then, by sliding the tooth-cutting cutter along the outer wall of the rotating shaft, the spheres are returned to the inner wall of the three circular slots by the springs after the tooth-cutting cutter is removed. This achieves the disassembly of the tooth-cutting cutter. When it is necessary to install the tooth-cutting cutter, the opposite operation can be performed, thus effectively saving workers' time in replacing the tooth-cutting cutter.

[0026] The fixed assembly 3 includes a rotary motor 301, a base plate 302 is fixedly sleeved on the outer edge of the output shaft of the rotary motor 301, a servo motor 303 is fixedly mounted on the top of the base plate 302, a worm gear 304 is fixedly sleeved on the outer edge of the output shaft of the servo motor 303, a worm 305 is meshed on the outer edge of the worm gear 304, a threaded rod 306 is fixedly mounted on the outer wall of the worm 305, a slider 307 is threadedly connected to the outer wall of the threaded rod 306, a trapezoidal block 308 is fixedly mounted on the top of the slider 307, and a placement plate 309 is provided on the top of the worktable 1, with a second groove 310 opened on the top of the placement plate 309.

[0027] In the above structure, by setting the fixing component 3, the diamond wheel body 4 is placed on top of the fixing component 3, thereby fixing the inner wall of the diamond wheel body 4 and thus positioning the diamond wheel body 4.

[0028] In a preferred embodiment: the tooth-cutting assembly 10 includes a second servo motor 101, a rotating shaft 102 is fixedly sleeved on the outer edge of the power output shaft of the second servo motor 101, a second circular groove 103 is formed on the inner wall of the rotating shaft 102, a third circular groove 104 is formed on the outer wall of the rotating shaft 102, a sleeve 105 is fixedly installed on the inner wall of the second circular groove 103, one end of a spring 106 is fixedly connected to the inner wall of the sleeve 105, a ball 107 is fixedly connected to the other end of the spring 106, a tooth-cutting cutter 108 is provided on the outer wall of the rotating shaft 102, and a slot 109 is formed on the inner wall of the tooth-cutting cutter 108.

[0029] In a preferred embodiment: there are three sleeves 105, three springs 106 and three balls, and each sleeve 105, spring 106 and ball 107 is a group, which is disposed in the inner cavity of the second circular groove 103. There are three circular grooves 104 and three slots 109, and the three circular grooves 104 and three slots 109 are arranged opposite to each other. The circular grooves 104 are located in the inner wall of the third circular groove 104 and are adapted to the slots 109. The diameter of the ball 107 is larger than the diameter of the outer wall of the third circular groove 104.

[0030] In the above structure, by setting up the spheres 107, springs 106, circular grooves 104, and slots 109, when replacing the toothed cutter 108, by rotating the toothed cutter 108, the three spheres 107, which are adapted to the shape of the three slots 109, will slide out of the three slots 109. As the three spheres 107 disengage from the inner wall of the slots 109, they will drive the three springs 106 to move closer to the inner wall of the three sleeves 105. Then, by sliding the toothed cutter 108 out along the outer wall of the rotating shaft 102, after the toothed cutter 108 is removed, the spheres 107 will return to the inner wall of the circular grooves 104 under the rebound of the springs 106, thereby realizing the disassembly of the toothed cutter 108. When it is necessary to install the toothed cutter 108, the opposite operation can be performed.

[0031] In a preferred embodiment: the inner wall of the circular groove 5 is in contact with the inner wall of the placement plate 309, and the outer wall of the placement plate 309 is rotatably disposed from the inner wall of the circular groove 5.

[0032] In the above structure, by setting the circular groove 5 and the placement plate 309, the outer wall of the placement plate 309 will slide along the inner wall of the circular groove 5.

[0033] In a preferred embodiment: the number of servo motor 303, worm gear 304, worm 305, threaded rod 306 and slider 307 are four, and each servo motor 303, worm gear 304, worm 305, threaded rod 306 and slider 307 is arranged as a group in the inner cavity of the placement plate 309;

[0034] In the above structure, by configuring the servo motor 303, worm gear 304, worm 305, threaded rod 306, and slider 307, the outer edges of the power output shafts of the four servo motors 303 drive the four worm gears 304 to rotate. This causes the outer edges of the four worm gears 304 to mesh and rotate with the outer edges of the four worms 305. Consequently, the four worms 305 drive the threaded rod 306 to rotate, thus enabling the four threaded rods 306 to drive the slider 307 to slide.

[0035] In a preferred embodiment: there are four trapezoidal blocks 308 and four sliding grooves 310, and the outer wall of each trapezoidal block 308 is slidably fitted to the inner wall of the sliding groove 310;

[0036] In the above structure, by setting the trapezoidal blocks 308 and the second slide groove 310, the outer walls of the four trapezoidal blocks 308 can slide along the inner wall direction of the four slide grooves 310.

[0037] In a preferred embodiment: the electric push rod 6, the square block 7, the slide groove 8, the fixed block 9, and the toothed assembly 10 are considered as a single movable assembly, and the number of such movable assemblies is two;

[0038] In the above structure, by setting the electric push rod 6, square block 7, slide groove 8, fixing block 9 and tooth-cutting assembly 10, when the diamond wheel body 4 is toothed, the electric push rod 6, square block 7, slide groove 8, fixing block 9 and tooth-cutting assembly 10 set on both sides of the diamond wheel body 4 will perform tooth-cutting operation on the outer wall of the diamond wheel body 4.

[0039] Working principle: When using this device, the main body 4 of the diamond wheel is placed on top of the placement plate 309. Then, by starting the servo motor 303, the outer edges of the power output shafts of the four servo motors 303 drive the four worm gears 304 to rotate. This causes the outer edges of the four worm gears 304 to mesh with the outer edges of the four worms 305, causing the four worms 305 to drive the threaded rods 306 to rotate. When the threaded rods 306 rotate, they drive the four sliders 307 to move. This causes the four sliders 307 to drive the four trapezoidal blocks 308 to move along the inner wall of the four sliding grooves 310 towards the inner wall of the main body 4 of the diamond wheel, thus fixing the main body 4 of the diamond wheel. Then, by starting the electric push rod 6, the telescopic end of the electric push rod 6 drives the fixed block 9 to slide along the inner wall of the sliding groove 8. This causes the sliding fixed block 9 to drive the toothed assembly 10 to move closer to the main body 4 of the diamond wheel. Then, by starting the servo motor 101...

[0040] The outer edge of the power output shaft of the servo motor 101 drives the rotating shaft 102 to rotate, causing the tooth-cutting cutter 108, which is sleeved on the outer wall of the rotating shaft 102, to cut teeth on the outer wall of the diamond wheel body 4. Simultaneously, when replacing the tooth-cutting cutter 108, rotating it causes the three spheres 107, which are adapted to the shape of the three slots 109, to slide and disengage from the slots 109, thereby causing the three spheres 107 to disengage from the inner wall of the slots 109. The three springs 106 will move closer to the inner wall of the three sleeves 105. Then, the tooth cutter 108 is slid out along the outer wall of the rotating shaft 102. After the tooth cutter 108 is removed, the ball 107 will be reset to the inner wall of the circular groove 104 under the rebound of the spring 106, thereby realizing the disassembly of the tooth cutter 108. When it is necessary to install the tooth cutter 108, it can be achieved by the reverse operation.
