Description

Technical Field

[0001] The invention relates to the technical field of gear processing, in particular to high-precision gear tooth profile processing equipment. Background Art

[0002] Gears are a common transmission part used in all walks of life. In the gear processing process, grinding the gear tooth shape is a very important part. Grinding the gear can not only improve the gear accuracy, but also extend the service life of the gear, but also improve the gear's carrying capacity and improve the surface quality of the gear. In the process of grinding the gear, the gear can be ground by spraying grinding fluid onto the gear surface. After the grinding fluid is used, if it cannot be collected in time, a large amount of material will be wasted.

[0003] In order to overcome the above-mentioned defects, prior art 1 (application number CN202310762678.2, Chinese patent application with application date 2023-06-27) is a high-efficiency grinding machine for the tooth surface of noise-reducing gears, which effectively ensures the tooth surface finishing effect, is easy to clean, reduces abrasive loss, has high grinding efficiency, good system stability, high production efficiency, and high reliability. In addition, it is provided with an abrasive recovery device that can recycle the grinding fluid. Prior art 2 (application number CN202223369315.2, Chinese patent application with application date 2022-12-15) is a double-sided grinding machine with the function of recovering and cooling the grinding fluid, which has the effect of facilitating filtering, cooling and reusing the grinding fluid, which is beneficial to saving resources and reducing environmental pollution.

[0015] Compared with the prior art, the beneficial effects of the present invention are: adopting a new structural design, the gear can be evenly ground by setting a nozzle that can swing back and forth, thereby improving the grinding effect; and a material blocking component and a material receiving component are also provided, so that the grinding liquid can be concentrated and collected, which is convenient for the staff to reuse the grinding liquid and will not cause the waste of the grinding liquid. The specific contents are as follows: When the high-precision gear tooth processing equipment is working, the gear to be ground is installed on the connecting shaft. At this time, the motor works, driving the connecting shaft and the gear to rotate. At the same time, the nozzle sprays abrasive to grind the gear. The work process is fast and convenient, and the work efficiency is high.

[0016] Furthermore, when the motor and the connecting shaft are working, the connecting shaft drives the rotating shaft to rotate through the pulley.

[0017] In this high-precision gear tooth processing equipment, when the nozzle is working, the baffle plays a role in blocking the grinding fluid, and when the connecting shaft rotates, the connecting shaft drives the circular plate and the main magnet to rotate synchronously, and then the main magnet will intermittently approach the auxiliary magnet. At this time, the baffle makes reciprocating linear motion in the horizontal direction under the action of the mutually repulsive magnetic force, the limit rod and the first spring and the limit plate, that is, the baffle is in a vibrating state, which is convenient for quickly shaking off the grinding fluid and then being collected by the receiving frame.

When the side rod makes reciprocating linear motion in the vertical direction, the side rod will drive the protrusion to move synchronously, and then the material receiving frame will make reciprocating linear motion in the horizontal direction under the action of the protrusion, the force block, the long pin and the connecting spring, so that the material receiving frame can discharge the grinding fluid faster, thereby improving the collection efficiency.

[0019] Furthermore, the protrusions are evenly spaced on the surface of the side rod, thereby increasing the working frequency of the material receiving frame and being able to better collect the grinding fluid. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Embodiment 1: During operation, the swingable nozzle 17 is used to achieve uniform grinding at multiple angles, thereby improving the grinding accuracy. Figure 1 , Figure 3-Figure 8 As shown, it includes a working plate 1, the upper surface of the working plate 1 is fixedly connected to a vertical plate 2, and a motor 3 is bolted to the outer wall of the vertical plate 2, and the output end of the motor 3 is fixedly connected to a connecting shaft 4, the upper surface of the working plate 1 is fixedly connected to an auxiliary plate 5, and the left and right surfaces of the auxiliary plate 5 are both convex, and the right surface of the auxiliary plate 5 is rotatably connected to a force-bearing plate 15, and the surface of the force-bearing plate 15 is fixedly connected to a nozzle 17, a swing assembly is arranged between the auxiliary plate 5 and the force-bearing plate 15, the swing assembly includes a connecting rod 18 fixedly connected to the surface of the force-bearing plate 15, and when the swing assembly is working, the nozzle 17 swings back and forth.

[0024] A material blocking assembly is provided on the left side of the vertical plate 2, and the material blocking assembly includes a baffle 7 movably arranged on the front side of the vertical plate 2. When the material blocking assembly is working, the baffle 7 moves back and forth. A material receiving assembly is provided on the lower surface of the working plate 1, and the material receiving assembly includes a material receiving frame 26 movably arranged on the lower surface of the working plate 1. When the material receiving assembly is working, the material receiving frame 26 moves back and forth.

[0025] The swing assembly also includes a rotating shaft 6 rotatably arranged inside the auxiliary plate 5 and inside the motor 3, and the rotating shaft 6 and the connecting shaft 4 are connected by a pulley, and the end of the rotating shaft 6 is fixedly connected to a cam 20, the upper surface of the working plate 1 is fixedly connected to a column 31, and the surface of the column 31 is slidably connected to a fixed block 32, and the right side of the fixed block 32 is fixedly connected to a side rod 24, and the upper surface of the side rod 24 is fixedly connected to a pressure plate 21 corresponding to the cam 20, and the lower surface of the fixed block 32 is fixedly connected to a return spring 33, and the other side of the return spring 33 is fixedly connected to the upper surface of the working plate 1.

[0026] The inner rod 14 is rotatably connected to the raised position on the right side of the auxiliary plate 5, and the surface of the inner rod 14 is fixedly connected to the force plate 15. The front view of the connecting rod 18 is an inverted "U" shape, and the inner wall of the connecting rod 18 is fitted with a lever 16. The left side of the lever 16 is fixedly connected to a cross bar 19, and the lower surface of the cross bar 19 is fixedly connected to a second spring 22, and the other side of the second spring 22 is connected to the raised position on the left side of the auxiliary plate 5. The lower surface of the pressure plate 21 is fixedly connected to a push rod 23 corresponding to the cross bar 19.

[0027] During operation, the gear to be ground is installed on the connecting shaft 4, and the motor 3 is working at this time. When the motor 3 is working, the connecting shaft 4 and the gear are driven to rotate, and at the same time, the nozzle 17 sprays abrasive to grind the gear. The working process is quick and convenient. When the motor 3 and the connecting shaft 4 are working, the connecting shaft 4 drives the rotating shaft 6 to rotate through the pulley. When the rotating shaft 6 rotates, it drives the cam 20 to rotate synchronously. At this time, the cam 20 will intermittently push the pressure plate 21, the side rod 24 and the fixed block 32. When the cam 20 pushes the pressure plate 21, the pressure plate 21 squeezes the reset spring 33 through the fixed block 32. When the cam 20 continues to rotate until it does not push the pressure plate 21, the pressure plate 21 is fixed. The fixed block 32 returns to its original position under the action of the reset spring 33, that is, the pressure plate 21, the side rod 24 and the fixed block 32 make reciprocating linear motion in the vertical direction, and then the push rod 23 will intermittently press the cross bar 19. When the cross bar 19 is pressed, the cross bar 19 moves in the direction of squeezing the second spring 22. When the cross bar 19 is not pressed, the cross bar 19 is reset under the action of the second spring 22, that is, the cross bar 19 makes reciprocating linear motion in the vertical direction. The cross bar 19 can drive the force plate 15 and the nozzle 17 to swing around the inner rod 14 through the shift rod 16 and the connecting rod 18, so that the working range of the nozzle 17 is increased, the grinding effect is better, and the work efficiency is improved.

[0028] Embodiment 2: Different from Embodiment 1, the baffle plate 7 can be moved in the horizontal direction by setting the baffle assembly, so that the grinding liquid can be collected quickly. Figure 1 and Figure 2As shown, the material baffle assembly also includes a circular plate 10 fixedly connected to the surface of the connecting shaft 4, and the surface of the circular plate 10 is fixedly connected to a main magnet 11, the baffle 7 is slidably connected to the connecting shaft 4, and the surface of the baffle 7 is fixedly connected to a secondary magnet 13, the secondary magnet 13 has the same magnetic pole as the main magnet 11 at adjacent positions, a limiting rod 8 is fixedly connected to the inner wall of the vertical plate 2, and the limiting rod 8 is movably connected to the baffle 7, and the limiting rod 8 is symmetrically distributed about the center of the baffle 7, the end of the limiting rod 8 is fixedly connected to the limiting plate 12, and the surface of the limiting plate 12 is fixedly connected to the first spring 9, and the other side of the first spring 9 is fixedly connected to the surface of the baffle 7.

[0029] When the nozzle 17 is working, the baffle 7 plays a role in blocking the grinding liquid, and when the connecting shaft 4 rotates, the connecting shaft 4 drives the circular plate 10 and the main magnet 11 to rotate synchronously, and then the main magnet 11 will intermittently approach the secondary magnet 13. When the main magnet 11 approaches the secondary magnet 13, the baffle 7 moves in the direction of squeezing the first spring 9 under the action of the limit rod 8, and when the main magnet 11 is away from the secondary magnet 13, the baffle 7 returns to its original position under the action of the first spring 9, and repeats the above process. At this time, the baffle 7 makes reciprocating linear motion in the horizontal direction, that is, the baffle 7 is in a vibrating state, which is convenient for quickly shaking off the grinding liquid and then being collected by the receiving frame 26.

[0030] Embodiment 3: Different from Embodiment 2, the receiving frame 26 can be vibrated in the horizontal direction by setting the receiving assembly, so that the grinding liquid can be collected without remaining on the receiving frame 26. Figure 9-11 As shown: The material receiving assembly also includes a lower connecting plate 27 fixedly connected to the lower surface of the working plate 1, and a long pin 28 is fixedly connected to the surface of the lower connecting plate 27, and the long pin 28 is slidably connected to the material receiving frame 26, and the end of the long pin 28 is a convex shape, and the long pin 28 is symmetrically distributed about the center of the material receiving frame 26, and the surface of the side rod 24 is fixedly connected to the protrusion 25, and the protrusion 25 is evenly spaced on the surface of the side rod 24.

[0031] The receiving frame 26 is a structure that is wide at the top and narrow at the bottom, and a force block 30 is fixedly connected to the left surface of the receiving frame 26 , and a connecting spring 29 is fixedly connected to the surface of the receiving frame 26 , and the other side of the connecting spring 29 is fixedly connected to the surface of the lower connecting plate 27 .

[0032] During operation, a collecting bucket can be placed at the lower end of the material receiving frame 26. When the side rod 24 makes reciprocating linear motion in the vertical direction, the side rod 24 will drive the protrusion 25 to move synchronously. When the protrusion 25 moves, it will intermittently contact the force block 30. When the force block 30 is pushed, the force block 30 drives the material receiving frame 26 to move in the direction of squeezing the connecting spring 29. When the force block 30 is not squeezed, the material receiving frame 26 returns to its original position under the action of the connecting spring 29 and the long pin 28, and the above process is repeated. Then, the material receiving frame 26 makes reciprocating linear motion in the horizontal direction, and then the material receiving frame 26 can discharge the grinding liquid faster, thereby improving the collection efficiency. The protrusions 25 are evenly spaced on the surface of the side rod 24, thereby increasing the working frequency of the material receiving frame 26 and better collecting the grinding liquid.

[0033] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
