Description

Technical Field

[0001] The present invention relates to the technical field of gear processing and gear shaping devices, and more particularly to a high-precision gear shaping device suitable for gear processing. Background Art

[0002] Gears are mechanical components that transmit motion and power through the continuous meshing of teeth. Because they provide smooth transmission, gears are used in various fields, including industry, transportation, and daily life. Gears play a vital role in various fields, providing convenience and efficiency for modern life.

[0004] The above technical solution solves the problems of the existing technical device having a complex structure, being unsuitable for processing a small number of internal gears, and being prone to injury to people. However, the existing gear shaping device usually uses a reciprocating tool to cut the tooth groove on the inner side of the ring. During the tooth groove cutting process of the gear, the tool needs to move vertically up and down to gradually cut the depth of the tooth groove. The repeated reciprocating cutting action increases the gear processing steps. In addition, after the tooth groove of the ring is processed, the inner wall of the tooth groove needs to be chamfered in the next step, which increases the cutting step of the inner teeth of the ring and affects the processing efficiency of the gear. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-precision gear shaping device suitable for gear processing to solve the problems raised in the above background technology:

The movable ring is squeezed and moves to squeeze the first spring. At this time, the movable ring moves with multiple rotating rods, and the multiple rotating rods move with multiple cutting seats outward to adjust the position of the cutting seat. The rotation of the rotating shaft drives the tool to rotate at high speed, and the reciprocating rod moves downward. The high-speed rotating tool cuts grooves on the inner side surface of the circular ring. During the high-speed rotation of the tool, multiple cutting seats follow the tool to rotate at high speed. Since the inner side surface of the cutting seat contacts the surface of the tool, the cutting seat rotates at high speed to chamfer the inner wall of the tooth groove. Compared with the traditional gear shaping device, during the gear processing process, the high-speed rotating tool cuts grooves on the inner side surface of the circular ring, and the tool rotates at high speed to cut, which increases the cutting speed of the tooth groove. At the same time, the cutting seat follows the tool movement to chamfer the inner wall of the tooth groove, reducing the number of steps in the gear processing process, thereby improving the gear processing efficiency.

After the guide rod is squeezed, it moves with multiple arc-shaped clamping plates toward the direction of the ring. The movement of the arc-shaped clamping plate moves with the two clamping blocks. When the two clamping blocks move to the surface of the ring, the second motor is stopped. Then the knob is manually turned to make the bidirectional screw rotate and drive the two clamping blocks to move toward each other in the slot to clamp and fix the ring. After the ring is clamped and fixed, it is processed to ensure the stability of the ring during processing.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1) When the high-precision gear shaping device suitable for gear processing is used, the thread wire is rotated by an external wrench. At this time, the thread wire moves toward the tool on the surface of the thread groove. The movable ring is squeezed and moves to squeeze the first spring. At this time, the movable ring moves with multiple rotating rods, and the multiple rotating rods move with multiple cutting seats outward to adjust the position of the cutting seat. The rotation of the rotating shaft drives the tool to rotate at high speed, and the reciprocating rod moves downward. The high-speed rotating tool cuts grooves on the inner side surface of the circular ring. During the high-speed rotation of the tool, multiple cutting seats follow the tool to rotate at high speed. Since the inner side surface of the cutting seat contacts the surface of the tool, the cutting seat rotates at high speed to chamfer the inner wall of the tooth groove. Compared with the traditional gear shaping device, during the gear processing process, the high-speed rotating tool cuts grooves on the inner side surface of the circular ring. The high-speed rotation of the tool increases the cutting speed of the tooth groove. At the same time, the cutting seat follows the tool movement to chamfer the inner wall of the tooth groove, reducing the number of steps in the gear processing process, thereby improving the gear processing efficiency.

[0026] 2) When the high-precision gear shaping device suitable for gear processing is in use, an external clamping tool is used to clamp the ring and place it flat between multiple arc-shaped clamping plates. Then the second motor rotates to drive the third gear to rotate, and the rotation of the gear drives the rotating drum to rotate. At this time, multiple arc blocks rotate to extrude the guide rod. After the guide rod is squeezed, it moves with multiple arc-shaped clamping plates toward the direction of the ring. The movement of the arc-shaped clamping plate drives the two clamping blocks to move. When the two clamping blocks move to the surface of the ring, the second motor is stopped. Then the knob is manually turned to make the bidirectional screw rotate and drive the two clamping blocks to move toward each other in the slot to clamp and fix the ring. After the ring is clamped and fixed, the ring is processed through the processing steps in the embodiment to ensure the stability of the ring during processing. Compared with traditional clamping devices, the clamping tool is more stable after clamping the ring, and multiple arc blocks move at the same time, making it more convenient and quick for the clamping tool to clamp the ring, further improving the processing speed of the gear.

The rotation angle of the driving device is controllable to achieve orderly cutting of the tooth grooves on the inner side of the ring 3. The ring 3 to be processed is placed above the base 2. A through-type reciprocating rod 4 is slidably connected to the surface of the device body 1. A rotation groove 18 is provided on the bottom surface of the reciprocating rod 4. A tool 5 for processing the ring 3 is rotatably connected inside the rotation groove 18. The tool 5 is a high-speed rotating tool 5. Compared with the traditional reciprocating cutting tool, the high-speed rotating tool 5 makes the cutting of the tooth groove faster. A plurality of slide grooves 6 are provided on both sides of the tool 5. The interior of any slide groove 6 is slidably connected to a slider 7 matched thereto. A cutting seat 8 for processing the ring 3 is fixedly installed on the surface of any slider 7. The cutting seat 8 performs chamfering on the inner wall of the tooth groove as the tool 5 rotates. The inner side surface of the cutting seat 8 contacts the surface of the tool 5. A through-type rotating shaft 9 is fixedly installed on the surface of the tool 5. The tool 5 is rotatably connected to the rotating groove 18 through the rotating shaft 9. The surface of the rotating shaft 9 is correspondingly slidably connected to a movable ring 10. Any movable ring 10 is connected to the surface of the tool 5. A first spring 11 is elastically connected between them, and the first spring 11 is used for the movement reset of the movable ring 10. A rotating rod 12 is provided between the cutting seat 8 and the movable ring 10. A thread groove 13 is correspondingly provided on the surface of the rotating shaft 9. The surface of the thread groove 13 is threadedly connected with a threaded wire 14. The side of the threaded wire 14 contacts the surface of the movable ring 10. The threaded wire 14 is rotated by an external wrench. At this time, the threaded wire 14 moves toward the tool 5 on the surface of the thread groove 13. The movable ring 10 is squeezed and then moves to squeeze the first spring 11. At this time, the movable ring 10 moves with multiple rotating rods 12, and the multiple rotating rods 12 move with multiple cutting seats 8 to move outward, so as to adjust the position of the cutting seat 8. The rotating shaft 9 rotates The tool 5 is driven to rotate at high speed, and the reciprocating rod 4 moves downward. The high-speed rotating tool 5 cuts a groove on the inner side surface of the ring 3. During the high-speed rotation of the tool 5, multiple cutting seats 8 follow the tool 5 to rotate at high speed. Since the inner side surface of the cutting seat 8 is in contact with the surface of the tool 5, the cutting seat 8 rotates at high speed to chamfer the inner wall of the tooth groove. Compared with the traditional gear shaping device, during the gear processing process, the high-speed rotating tool 5 cuts a groove on the inner side surface of the ring 3, and the tool 5 rotates at high speed to cut, which increases the cutting speed of the tooth groove. At the same time, the cutting seat 8 follows the tool 5 to chamfer the inner wall of the tooth groove, reducing the process in the gear processing process, thereby improving the gear processing efficiency.

[0041] The first spring 11 is sleeved on the surface of the rotating shaft 9, one end of the first spring 11 is fixedly connected to the surface of the tool 5, the other end of the first spring 11 is fixedly connected to the movable ring 10, and the two ends of the rotating rod 12 are rotatably connected to the cutting seat 8 and the movable ring 10 respectively.

A micro motor 17 is fixedly installed on the inner wall of the rotating groove 18. The micro motor 17 is a conventional electric motor in the prior art. The output end of the micro motor 17 is fixedly connected to the surface of the second gear 16. The first gear 15 and the second gear 16 mesh with each other, so that the high-speed rotation of the tool 5 is more stable.

[0043] A movable frame 19 is fixedly mounted on the top surface of the reciprocating rod 4 , a turntable 21 is rotatably connected to one side of the movable frame 19 , a rotating column 20 is fixedly mounted on the surface of the turntable 21 , and the rotating column 20 passes through the interior of the movable frame 19 .

[0044] A support base 22 is fixedly installed on the top surface of the device body 1, and a first motor 23 is fixedly installed on the top surface of the support base 22. The first motor 23 is a conventional electric motor in the prior art. The speed of the first motor 23 is controllable. The output end of the first motor 23 is fixedly connected to the turntable 21. The rotation of the first motor 23 drives the turntable 21 to rotate, and the rotation of the turntable 21 drives the rotating column 20 to rotate, so that the movable frame 19 moves up and down and drives the reciprocating rod 4 to move up and down.

[0045] Two lubrication pipes 24 corresponding to the processing positions of the ring 3 are fixedly installed inside the device body 1. The lubrication pipes 24 are connected to an external oil pump through a hose. The oil pump is a conventional oil pump in the prior art. The oil pump extracts cutting oil and lubricates the cutting position and cools the tool 5 through the two lubrication pipes 24.

[0046] The use steps of the present invention are as follows: when using the high-precision gear shaping device suitable for gear processing, the ring 3 to be processed is first fixed on the top of the seat 2, and then the threaded wire 14 is rotated by an external wrench. At this time, the threaded wire 14 moves toward the tool 5 on the surface of the thread groove 13. The movable ring 10 is squeezed and moves to squeeze the first spring 11. At this time, the movable ring 10 moves with the multiple rotating rods 12, and the multiple rotating rods 12 move with the multiple cutting seats 8 to move outward. At this time, the cutting seat 8 moves with the slider 7 to move inside the slide groove 6, and the multiple cutting seats 8 move against the surface of the tool 5. When the position adjustment of the cutting seat 8 is completed, the micro motor 17 rotates to rotate the second gear 16, and the second gear 16 rotates to rotate the first gear 15 rotates, at this time the rotating shaft 9 rotates with the tool 5 to rotate at high speed, the oil pump works to extract cutting oil, and lubricates the cutting position and cools the tool 5 through the two lubrication pipes 24, then the first motor 23 rotates to rotate the turntable 21 (the speed of the first motor 23 is controllable), the turntable 21 rotates with the rotating column 20, so that the movable frame 19 moves up and down and drives the reciprocating rod 4 to move up and down, the reciprocating rod 4 moves downward and drives the tool 5 to move downward to contact the surface of the ring 3 to be processed, as the reciprocating rod 4 continues to move downward, the high-speed rotating tool 5 cuts a groove on the inner side of the ring 3, and during the high-speed rotation of the tool 5, multiple cutting seats 8 follow the tool 5 to rotate at high speed. Surface contact, at this time, when the tool 5 is cutting the tooth groove of the ring 3, the cutting seat 8 rotates at high speed to chamfer the inner wall of the tooth groove. When one tooth groove of the ring 3 is processed, the reciprocating rod 4 moves upward with the tool 5, and then the driving device drives the seat 2 to move (the angle of rotation of the driving device is controllable), and the reciprocating rod 4 moves downward with the tool 5 to continue processing the next tooth groove. This solution rotates the thread wire 14 by an external wrench. At this time, the thread wire 14 moves toward the tool 5 on the surface of the thread groove 13. The movable ring 10 is squeezed and then moves to squeeze the first spring 11. At this time, the movable ring 10 moves with multiple rotating rods 12, and the multiple rotating rods 12 move with multiple cutting seats 8 to move outward, cutting The seat 8 is position-adjusted, the rotating shaft 9 rotates with the tool 5 to rotate at high speed, the reciprocating rod 4 moves downward, and the high-speed rotating tool 5 cuts a groove on the inner side surface of the ring 3. During the high-speed rotation of the tool 5, multiple cutting seats 8 follow the tool 5 to rotate at high speed. Since the inner side surface of the cutting seat 8 contacts the surface of the tool 5, the cutting seat 8 rotates at high speed to chamfer the inner wall of the tooth groove. Compared with the traditional gear shaping device, during the gear processing process, the high-speed rotating tool 5 cuts a groove on the inner side surface of the ring 3, and the tool 5 rotates at high speed to cut, which increases the cutting speed of the tooth groove. At the same time, the cutting seat 8 follows the tool 5 to chamfer the inner wall of the tooth groove, reducing the process in the gear processing process, thereby improving the gear processing efficiency.

A plurality of arc blocks 28 are fixedly installed on the surface of the rotating drum 27. The plurality of arc blocks 28 move simultaneously, making it more convenient and quick for the clamping tool to clamp the ring 3. A plurality of fixed plates 29 are fixedly installed on the top surface of the fixed seat 25. The surface of any one of the fixed plates 29 is slidably connected with a through-type guide rod 30.

An arc splint 31 is fixedly installed on the surface of one end of the guide rod 30, and the other end of the guide rod 30 contacts the arc block 28. The ring 3 is clamped by an external clamping tool and placed flatly between the plurality of arc splints 31, and then the second motor The rotation of 40 drives the third gear 38 to rotate, and the rotation of the tooth 37 drives the rotating drum 27 to rotate. At this time, multiple arc blocks 28 rotate to extrude the guide rod 30. After the guide rod 30 is squeezed, it moves with multiple arc clamps 31 toward the ring 3. The arc clamp 31 moves with two clamping blocks 34. When the two clamping blocks 34 move to the surface of the ring 3, the second motor 40 is stopped, and then the knob 36 is manually rotated to make the bidirectional screw rod 35 rotate and drive the two clamping blocks 34 to move toward each other in the slot 33 to clamp and fix the ring 3. After the ring 3 is clamped and fixed, the ring 3 is processed to ensure the stability of the ring 3 during processing. Compared with traditional clamping devices, the clamping tool is more stable after clamping the ring 3, and multiple arc blocks 28 move at the same time, making it more convenient and quick for the clamping tool to clamp the ring 3, further improving the processing speed of the gear.

The interior of any slot 33 is rotatably connected to a two-way screw rod 35, and the two clamping blocks 34 are threadedly connected to the surface of the two-way screw rod 35. A knob 36 is fixedly installed on the surface of any two-way screw rod 35. Manually turning the knob 36 causes the two-way screw rod 35 to rotate and move the two clamping blocks 34 toward each other in the slot 33 to clamp and fix the ring 3.

[0051] The use steps of the present invention are as follows: when the high-precision gear shaping device suitable for gear processing is used, the ring 3 to be processed needs to be fixed before processing. In the initial state, the distance between the two clamping blocks 34 is greater than the thickness of the ring 3. The ring 3 is clamped by an external clamping tool and placed flat between multiple arc-shaped clamping plates 31. Then the second motor 40 rotates to drive the third gear 38 to rotate, and the rotating gear 37 rotates to drive the rotating drum 27 to rotate.
