Description

Technical Field

[0001] This invention relates to the field of CNC machining technology, and in particular to a high-precision gear chamfering CNC integrated machining equipment. Background Technology

[0002] In the field of mechanical manufacturing, gears are key transmission components, and gear chamfering is an important process for improving gear meshing quality and reducing stress concentration. With the continuous improvement of industrial automation, the requirements for the efficiency and precision of gear chamfering equipment are becoming increasingly stringent.

[0003] Currently, most gear chamfering processing equipment on the market has significant defects. For example, the invention patent with publication number CN114101803A entitled "A Gear Chamfering Device" solves the problem of semi-automatic chamfering processing, but it cannot achieve automatic loading and unloading and integrated processing. In the traditional processing process, manual loading, positioning and unloading of gears are usually relied upon. This method is not only inefficient and difficult to meet the needs of mass production, but also has positioning deviations due to manual operation, which seriously affects the processing accuracy of gear chamfering. In addition, frequent manual contact with the equipment also poses a high safety hazard and is not suitable for the requirements of modern intelligent manufacturing for efficient, precise and automated processing equipment. Therefore, a high-precision gear chamfering CNC integrated processing equipment is provided. Summary of the Invention

[0004] This invention addresses the problem that existing equipment cannot automatically perform operations such as loading, positioning, and unloading, resulting in low efficiency in mass production. It provides a high-precision gear chamfering CNC integrated machining equipment that can automatically load, position, and unload during the machining process, eliminating the need for manual operation, thus improving machining efficiency and effectively solving the problems mentioned in the background art.

[0005] The technical solution adopted by the present invention to solve the above problems is as follows: A high-precision gear chamfering CNC integrated machining equipment includes an operating table with two movable drive motors mounted on it. Each drive motor output has a detachable cutting tool. The operating table also has an extension seat with a drive plate that can move back and forth. A material support is located at the front end of the drive plate, and a feeding device is mounted on the upper end of the extension seat. The feeding device includes a feeding trough containing multiple gears. A stop gate is located on one side of the feeding trough. When the drive plate moves backward, the stop gate flips downward, causing the gears to fall into the material support. A lower... The material trough, when the drive plate moves forward, causes the material support seat to flip downward and the gear to fall into the material trough; the upper part of the operating platform is also equipped with a fixing device, which includes a frame, and inside the frame is a telescopic pressure rod that can move up and down. The lower end of the telescopic pressure rod is equipped with an arc-shaped pressure seat that cooperates with the gear. The frame is also equipped with multiple positioning clamps. When the telescopic pressure rod moves downward, it can cause the positioning clamps to move inward and the arc-shaped pressure seat to move downward. When the telescopic pressure rod moves downward to the point where the arc-shaped pressure seat contacts the gear and continues to move downward to press and fix it, the positioning clamps can move to both sides away from the arc-shaped pressure seat.

[0006] The upper sides of the operating platform are provided with bases, and motor mounts are slidably connected to the bases. The drive motors are fixed on the corresponding motor mounts, and the bases are also provided with first drivers for controlling the movement of the motor mounts.

[0007] A drive seat is slidably connected to the extension seat, a drive plate is mounted on the drive seat, and a second driver is provided on one side of the extension seat for controlling the movement of the drive seat.

[0008] The upper end of the extension seat is provided with a support plate, the feeding trough is installed on the support plate, the bottom of the feeding trough is provided with multiple round sliding rods, and a baffle plate is provided on one side of the feeding trough.

[0009] The lower end of the drive plate is provided with a vertical plate, and a long slider is slidably connected to the front end of the vertical plate. The material support is hinged to the front end of the drive plate. The front end of the vertical plate is also provided with a first connecting rod. One end of the first connecting rod is hinged to the long slider, and the other end of the first connecting rod is hinged to the material support. Both ends of the long slider are fixed with a first movable pin that can move up and down.

[0010] The upper end of the extension seat is provided with a first guide frame on both sides, and the inner wall of the first guide frame is provided with a first horizontal groove and a first inclined groove that cooperate with the first live pin.

[0011] The bottom of the feeding trough is provided with a discharge port on one side. The inner wall of the bottom end of the feeding trough is also provided with a U-shaped frame. The gate is hinged to the U-shaped frame. Cranks are coaxially fixed on both sides of the gate. Two vertical plates are fixed to the lower end of the feeding trough. Small sliders are slidably connected to the inner wall of the vertical plates. A second movable pin that can move up and down is fixed to the small slider. A short keyway that cooperates with the second movable pin is opened on the crank.

[0012] The drive plate is provided with a second guide frame on both sides of the upper end, and the inner wall of the second guide frame is provided with a second horizontal groove and a second inclined groove that cooperate with the second live pin.

[0013] The upper end of the frame is fixedly connected to a U-shaped seat. The telescopic pressure rod includes an inner rod and an outer cylinder. The inner rod is slidably connected to the inner wall of the outer cylinder. The inner wall of the bottom end of the outer cylinder is provided with a first spring that cooperates with the inner rod. The arc-shaped pressure seat is fixedly connected to the lower end of the inner rod. The outer cylinder is slidably connected to the inner wall of the U-shaped seat. Both ends of the frame are slidably connected to long connecting plates. The positioning clamps are all installed on the corresponding long connecting plates. The inner ends of the two long connecting plates are provided with first sliding pins. The outer end face of the outer cylinder is fixedly connected to two first track frames. The inner walls of the first track frames are provided with short inclined grooves and long vertical grooves that cooperate with the first sliding pins.

[0014] Two square sliders are slidably connected to the inner end faces of the two long connecting plates. The positioning clamps are fixed to the lower end of the corresponding square sliders. Limiting plates are fixed to the front and rear sides of the inner end face of the frame. Double-headed telescopic pins are slidably connected to the inner walls of the limiting plates. The square sliders are slidably connected to the sides of the corresponding double-headed telescopic pins. Two second track frames are also fixed to the outer surface of the outer cylinder. The inner walls of the second track frames are provided with short vertical grooves and long inclined grooves that cooperate with the double-headed telescopic pins.

[0015] Compared with the prior art, the present invention has the following advantages: In use, when the drive plate moves backward to the designated position, even when the material support seat moves to the lower end of the stop gate, the stop gate can flip downward and open, allowing the gear to fall into the material support seat under gravity. When the drive plate moves forward, the material support seat supports the gear and moves forward. After the material support seat moves forward to the designated position, through the set fixing device, when the telescopic pressure rod moves downward, it can drive the arc-shaped pressure seat downward and also cause the positioning clamping rod to move inward. When the positioning clamping rod moves inward, it can clamp and position the gear on the material support seat, placing the gear in the designated position on the material support seat, thus making machining and cutting more precise. When the telescopic pressure rod continues to move downward, it can bring the arc-shaped pressure seat into contact with the gear. When the telescopic pressure rod continues to move downward, the arc-shaped pressure seat can squeeze the gear, thereby fixing the gear. At the same time, the positioning clamping rod can move to both sides, away from the arc-shaped pressure seat and the material support seat. For gears, the positioning clamp provides operating space for gear cutting when it moves outward. After fixing the gear, controlling two drive motors to move inward allows for gear cutting. After cutting, controlling the drive plate to move forward causes the material support to flip downward, allowing the gear to fall into the feeding trough. Guided by the feeding trough, the gear flows into a designated location for centralized collection. The automatic loading and unloading function eliminates inefficient and error-prone manual operations, significantly improving production efficiency and meeting the needs of large-scale industrial production. The integrated design combines loading / unloading with chamfering processes, simplifying the process, reducing equipment footprint, and minimizing the risk of errors during material handling. Simultaneously, it ensures high-precision machining, effectively improving gear meshing performance, reducing operating noise, guaranteeing the stability of the gear transmission system, and reducing enterprise safety production management costs.

Detailed Implementation

[0031] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0032] like Figures 1-14 As shown, this invention provides a high-precision gear chamfering CNC integrated machining equipment, including an operating table 1. Two movable drive motors 3 are mounted on the operating table 1, and each drive motor 3 has a detachable cutting tool at its output end. The operating table 1 also has an extension seat 7, on which a drive plate 14 capable of moving back and forth is mounted. A material support seat 16 is located at the front end of the drive plate 14. A feeding device is also mounted on the upper end of the extension seat 7. The feeding device includes a feeding trough 11, in which multiple gears are placed. A stop gate 24 is located on one side of the feeding trough 11. When the drive plate 14 moves backward, the stop gate 24 flips downward, causing the gears to fall into the material support seat 16. The upper end of the operating table 1 also has a lower... The material trough 56, when the drive plate 14 moves forward, can cause the material support seat 16 to flip downward and the gear to fall into the material trough 56; the upper end of the operating table 1 is also provided with a fixing device, which includes a frame 38. The frame 38 is provided with a telescopic pressure rod 37 that can move up and down. The lower end of the telescopic pressure rod 37 is provided with an arc-shaped pressure seat 55 that cooperates with the gear. The frame 38 is also provided with multiple positioning clamps 51. When the telescopic pressure rod 37 moves downward, it can cause the positioning clamps 51 to move inward and the arc-shaped pressure seat 55 to move downward. When the telescopic pressure rod 37 moves downward to the point that the arc-shaped pressure seat 55 contacts the gear and continues to move downward to squeeze and fix it, the positioning clamps 51 can move to both sides away from the arc-shaped pressure seat 55.

[0033] like Figures 1-11As shown, a carriage is provided at the lower end of the operating table 1. The carriage enables the device to be moved to a designated position and provides support for the installation of the entire equipment. The drive motor 3 provides rotational power to the cutting tool. A chuck is provided on the output shaft of the drive motor 3, and the cutting tool is fixed on the chuck, allowing for disassembly, positioning, maintenance, and replacement of the cutting tool. The drive motor 3, cutting tool, and chuck are all existing technologies and will not be described in detail. After the gear is moved to the designated position and fixed, the drive motor 3 is started, and then the two drive motors 3 are controlled to move inward, which allows the cutting tool to move inward to cut both sides of the gear, thereby machining the gear chamfer. The extension seat 7 is fixed to the rear side of the upper end of the operating table 1 by bolts. The extension seat 7 is used to install the drive plate 14, feeding device, and other components. The feeding trough 11 and the unloading trough are connected. The 56 is inclined, the feeding trough 11 is used to hold and arrange the gears to be processed, and the unloading trough 56 is used to receive and guide the processed gears; the frame 38 is used to support and install components such as the telescopic pressure rod 37; the gear in the feeding trough 11 can slide into the bottom of one side under the action of gravity, that is, move to the stop gate 24. When the drive plate 14 moves backward to the designated position, even when the material support seat 16 moves to the lower end of the stop gate 24, the stop gate 24 can be flipped down and opened, and the gear can fall into the material support seat 16 under the action of gravity. When the drive plate 14 is controlled to move forward, the material support seat 16 can support the gear to move forward. When the material support seat 16 moves forward to the designated position, through the set fixing device, when the telescopic pressure rod 37 moves downward, it can drive the arc-shaped pressure seat 55. The positioning clamp 51 moves inwards as the telescopic pressure rod 37 moves downwards, clamping and positioning the gear on the support seat 16. This ensures the gear is in the designated position on the support seat 16, allowing for more precise machining. As the telescopic pressure rod 37 continues to move downwards, the arc-shaped pressure seat 55 comes into contact with the gear. This pressure seat 55 then presses against the gear, fixing it in place. Simultaneously, the positioning clamp 51 moves to both sides, moving away from the arc-shaped pressure seat 55, the support seat 16, and the gear. This outward movement of the positioning clamp 51 provides operating space for gear cutting. After fixing the gear, controlling the two drive motors 3 to move inwards allows for further machining of the gear. The gear undergoes cutting processing. After cutting, the drive plate 14 is moved forward. When the drive plate 14 moves to the designated position, the material support 16 flips downward to allow the gear to fall into the unloading trough 56. Guided by the unloading trough 56, the gear flows into the designated position for centralized collection. Through automatic loading and unloading, inefficient and error-prone manual operation is completely eliminated, significantly improving production efficiency and meeting the needs of large-scale industrial production. The integrated design combines loading and unloading with chamfering processes, simplifying the process, reducing equipment footprint, and reducing the risk of errors caused by material transfer. At the same time, it ensures high-precision machining, effectively improves gear meshing performance, reduces operating noise, ensures the stability of the gear transmission system, and reduces the enterprise's safety production management costs.

[0034] The upper end of the operating table 1 is provided with bases 2 on both sides, and motor seats 4 are slidably connected to each base 2. The drive motors 3 are fixed on the corresponding motor seats 4. The base 2 is also provided with a first driver 5 for controlling the movement of the motor seats 4.

[0035] like Figure 3 As shown, the base 2 is fixed to the operating table 1 by bolts, and the drive motor 3 is fixed to the motor base 4 by bolts. The motor base 4 can slide left and right on the base 2. The driver can be an electric telescopic rod, a pneumatic telescopic rod, or a hydraulic telescopic rod, etc. When the first driver 5 is working, it can drive the motor base 3 to move left and right, that is, control the two drive motors 3 to move inward or outward synchronously. The driver is existing technology and will not be described in detail.

[0036] The extension seat 7 is slidably connected to the drive seat 9, the drive plate 14 is mounted on the drive seat 9, and a second driver 8 for controlling the movement of the drive seat 9 is provided on one side of the extension seat 7.

[0037] like Figure 4 As shown, the drive seat 9 can slide back and forth on the extension seat 7, that is, the limit drive plate 14 can only move back and forth. When the second driver 8 is working, it can control the drive seat 9 to move forward or to the right, thereby controlling the drive plate 14 to move forward or backward. The drive plate 14 is fixed to the drive seat 9 by bolts.

[0038] The upper end of the extension seat 7 is provided with a support plate 10, the feeding trough 11 is installed on the support plate 10, the bottom of the feeding trough 11 is provided with multiple round sliding rods 13, and a baffle plate 12 is provided on one side of the feeding trough 11.

[0039] like Figure 4 and Figure 5 As shown, multiple support rods are fixed to the lower surface of the support plate 10, and the support rods are all fixed to the extension seat 7. The support rods and the support plate 10 provide support and fixation for the feeding trough 11. The upper end of the support plate 10 is provided with a mounting frame, and the feeding trough 11 is fixed to the mounting frame. The mounting frame is existing technology and will not be described in detail. The sliding rod 13 can reduce the friction of the gear sliding downward on the inner wall of the feeding trough 11, so that the gear slides downward more smoothly. The baffle plate 12 can prevent the gear from moving further when it slides to the bottom of the feeding trough 11, so that the gear stops at the discharge port.

[0040] The drive plate 14 has a vertical plate 15 at its lower end. A long slider 18 is slidably connected to the front end of the vertical plate 15. The material support 16 is hinged to the front end of the drive plate 14. The front end of the vertical plate 15 is also provided with a first connecting rod 17. One end of the first connecting rod 17 is hinged to the long slider 18, and the other end of the first connecting rod 17 is hinged to the material support 16. Both ends of the long slider 18 are fixed with first movable pins 19 that can move up and down.

[0041] like Figure 8 As shown, the upright plate 15 is fixed on the lower surface of the drive plate 14. The long slider 18 can slide up and down on the front surface of the upright plate 15. When the first live pin 19 moves up and down, it can drive the long slider 18 to move up and down. When the long slider 18 moves up and down, it can drive the material support 16 to flip up and down through the hinge of the first connecting rod 17 and the material support 16, so that the material support 16 flips down when it moves to the designated position, and unloads the processed gear to the designated position.

[0042] The upper end of the extension seat 7 is provided with a first guide frame 20 on both sides. The inner wall of the first guide frame 20 is provided with a first horizontal groove 21 and a first inclined groove 22 that cooperate with the first live pin 19.

[0043] like Figure 8 As shown, the front end of the first guide frame 20 is fixed to the base 2, which is equivalent to being fixed to the operating table 1, and the rear end of the first guide frame 20 is fixed to the extension seat 7. When the drive plate 14 moves back and forth, it can drive the upright plate 15, the long slider 18, the first connecting rod 17, the material support seat 16, the first movable pin 19, etc., to move back and forth. When the first movable pin 19 engages with the inner wall of the first transverse groove 21, when the drive plate 14 and the first movable pin 19 move forward or backward, the first movable pin 19 can always maintain the specified position, that is, it will not move up or down, that is, the corresponding material support seat 16 will always be in a horizontal position and will not flip up or down. When the first movable pin 19 engages with the inner wall of the first inclined groove 22, when the drive plate 14 and the first movable pin 19 move forward or backward, the first movable pin 19 can move down or up. When the first movable pin 19 moves down, it can drive the material support seat 16 to flip down. When the first movable pin 19 moves up, it can drive the material support seat 16 to flip up and reset.

[0044] The bottom side of the feeding trough 11 is provided with a discharge port, and the inner wall of the bottom end of the feeding trough 11 is also provided with a U-shaped frame 23. The gate 24 is hinged to the U-shaped frame 23. Cranks 25 are coaxially fixed on both sides of the gate 24. Two vertical plates 28 are fixed to the lower end of the feeding trough 11. Small sliders 29 are slidably connected to the inner wall of the vertical plates 28. Second movable pins 26 that can move up and down are fixed to the small sliders 29. Short keyways 27 that cooperate with the second movable pins 26 are provided on the cranks 25.

[0045] like Figure 6 and Figure 9As shown, the gear can flow out from the feed port through the set feed port. The baffle 24 is installed at the feed port and can close the feed port under normal conditions. The U-shaped frame 23 and the vertical plate 28 are both fixed to the feed trough 11. The small slider 29 can slide up and down and is connected to the inner wall of the vertical plate 28, that is, the second movable pin 26 can only move up and down. The inner wall of the baffle 24 and the crank 25 is fixed to the rotating shaft. The outer surface of the rotating shaft is rotatably connected to the bearing seat. The bottom end of the bearing seat is fixed to the U-shaped frame 23, which limits the baffle 24 and the crank 25 to only flip on the U-shaped frame 23. When the baffle 24 flips down, it can open the feed port. The installation and shape of the second movable pin 26, the short keyway 27, and the crank 25 are as follows. Figure 9 As shown, when the second live pin 26 moves upward, the engagement between the second live pin 26 and the short keyway 27 drives the crank 25 to rotate upward and the stop gate 24 to rotate downward. When the stop gate 24 rotates downward, the feed port opens and the gear flows out. When the second live pin 26 moves downward, the stop gate 24 can rotate upward to the designated position, that is, the feed port is closed at this time.

[0046] The drive plate 14 is provided with a second guide frame 30 on both sides of the upper end. The inner wall of the second guide frame 30 is provided with a second horizontal groove 31 and a second inclined groove 32 that cooperate with the second live pin 26.

[0047] like Figures 8-9As shown, the second guide frame 30 is fixed on the drive plate 14. When the drive plate 14 moves back and forth, it can drive the second guide frame 30 to move back and forth. When the second movable pin 26 engages with the second transverse groove 31, when the drive plate 14 and the second guide frame 30 move forward or backward, the second movable pin 26 can always remain in the designated position and will not move, that is, the corresponding stop gate 24 will not flip, and the discharge port will always be in the closed state. When the second movable pin 26 engages with the second inclined groove 32, when the drive plate 14 and the second guide frame 30 move forward or backward, the second movable pin 26 can move downward or upward. The movement means that the corresponding gate 24 can flip upwards to close or downwards to open. Through the cooperation of the first movable pin 19, the first guide frame 20, the second movable pin 26, and the second guide frame 30, when the drive plate 14 moves forward from the rear end, the material support 16 will always remain horizontal as it moves forward due to the engagement of the first movable pin 19 with the first transverse groove 21. Under the engagement of the second movable pin 26 with the second transverse groove 31, the gate 24 will not flip, and the discharge port will always remain closed. When the drive plate 14, material support 16, etc., move to the middle, the drive motor 3, fixing device, etc., are controlled in coordination. During operation, the gear on the support seat 16 can be machined. After the gear is machined, the drive plate 14 is moved forward, allowing the first live pin 19 to enter the inner wall of the first inclined groove 22. At this time, the support seat 16 can flip downward, thus unloading the machined gear into the unloading groove 56. The second live pin 26 will still mesh with the second transverse groove 31, meaning the unloading port is still closed. After unloading, when the drive plate 14 is moved backward, the first live pin 19 can re-enter the inner wall of the first transverse groove 21, and the corresponding support seat 16 flips back to a horizontal position and remains stationary. When the drive plate 14 moves backward to engage the second inclined groove 32 of the second guide frame 30 with the second live pin 26, it can drive the second live pin 26 to move upward, that is, the corresponding stop gate 24 flips downward and the discharge port opens. The gear in the feed trough 11 will fall into the material support trough under the action of gravity. When the drive plate 14 continues to move forward, it can engage the second transverse groove 31 of the second guide frame 30 with the second live pin 26, that is, the stop gate 24 flips upward and closes the discharge port again. The whole process can automatically feed, process and discharge in a cycle, thereby replacing the traditional manual feeding and unloading.

[0048] The upper end of the frame 38 is fixedly connected to a U-shaped seat 39. The telescopic pressure rod 37 includes an inner rod 54 and an outer cylinder 52. The inner rod 54 is slidably connected to the inner wall of the outer cylinder 52. The inner wall of the bottom end of the outer cylinder 52 is provided with a first spring 53 that cooperates with the inner rod 54. The arc-shaped pressure seat 55 is fixedly connected to the lower end of the inner rod 54. The outer cylinder 52 is slidably connected to the inner wall of the U-shaped seat 39. The inner walls of both ends of the frame 38 are slidably connected to long connecting plates 40. The positioning clamps 51 are all installed on the corresponding long connecting plates 40. The inner ends of the two long connecting plates 40 are provided with first sliding pins 41. The outer end face of the outer cylinder 52 is fixedly connected to two first track frames 42. The inner walls of the first track frames 42 are provided with short inclined grooves 44 and long vertical grooves 43 that cooperate with the first sliding pins 41.

[0049] like Figures 10-14 As shown, frame 38 is fixed to the first guide frame 20 by multiple support columns, which is equivalent to being fixed to the operating table 1. The U-shaped seat 39 limits the movement of the outer cylinder 52 and the telescopic pressure rod 37, restricting their vertical movement; that is, it limits the movement of the arc-shaped pressure seat 55 to only vertical movement. The installation and shape of the telescopic pressure rod 37 are as follows: Figure 14 As shown, the inner rod 54 can slide up and down on the inner wall of the outer cylinder 52. The first spring 53 always exerts a downward driving force on the inner rod 54, so that the telescopic pressure rod 37 is in its longest state under normal conditions. When the telescopic pressure rod 37 moves downward, it can cause the arc-shaped pressure seat 55 to move downward. When the arc-shaped pressure seat 55 moves downward and contacts the gear, the telescopic pressure rod 37 continues to move downward, which can compress the first spring 53. The first spring 53 has a reaction force to squeeze the arc-shaped pressure seat 55 and the gear, thereby fixing the gear. Furthermore, the first spring 53 can prevent excessive compression from damaging the gear. Figure 10As shown, each drive motor 3 has a top plate 6 fixedly connected to its upper end, and each top plate 6 has a drive frame 33 fixedly connected to its upper end. Each telescopic pressure rod 37 has a drive pin 36 fixedly connected to its upper end. The inner wall of each drive frame 33 has an inclined sliding groove 34 and a short transverse groove 35 that cooperate with the drive pin 36. One end of each drive frame 33 is fixedly connected to the corresponding top plate 6, and the other end of each drive frame 33 is slidably connected to the corresponding top plate 6. When the two drive motors 3 and the top plate 6 move inward, the drive frame 33 can move smoothly. When the top plate 6 and drive frame 33 move inward, the drive pin 36 and telescopic pressure rod 37 move downward through the engagement of the drive pin 36 and the inclined slide groove 34. When the top plate 6 and drive frame 33 move inward to the point where the drive pin 36 enters the inner wall of the short transverse groove 35, the drive pin 36 and telescopic pressure rod 37 move downward to the lowest position. At this time, the drive motor 3, top plate 6, drive frame 33, etc. continue to move downward. Under the engagement of the short transverse groove 35, the drive pin 36 no longer moves downward or upward. The telescopic rod 37 and the arc-shaped pressure seat 55 are fixed to the gear. When the drive motor 3 continues to move inward, the cutting tool can cut the gear. When the drive motor 3 moves outward, the telescopic rod 37 can move upward and return to its initial position under the meshing of the drive frame 33 and the drive pin 36. Through the top plate 6, drive frame 33, drive pin 36, etc., the telescopic rod 37 can move downward to start working when the drive motor 3 moves, so that positioning, clamping and cutting are performed separately without movement interference. The telescopic rod 37 can also be directly driven to move downward or upward by adding a driver, but the cost is higher. The setting is selected according to the needs. The long connecting plate 40 can slide left and right on the inner wall of the frame 38. The positioning clamp 51 is installed at the lower end of the long connecting plate 40. When the long connecting plate 40 moves inward, it can drive the positioning clamp 51 to move inward. The installation and shape of the first sliding pin 41 and the first track frame 42 are as follows. Figure 13 As shown, both ends of the outer surface of the first sliding pin 41 are fixed with support seats. The bottom end of the support seat is fixed to the long connecting plate 40, which is equivalent to the first sliding pin 41 being fixed to the support seat. When the telescopic pressure rod 37 moves downward, it can drive the first track frame 42 to move downward. When the first track frame 42 moves downward, under the meshing of the first sliding pin 41 and the short inclined groove 44, it can drive the first sliding pin 41 and the long connecting plate 40 to move inward. When the long connecting plate 40 moves inward, it can drive the positioning clamp rod 51 to move inward, thereby causing the positioning clamp rod 51 to move inward to clamp and position the gear. When the telescopic pressure rod 37 moves downward to the point that the arc-shaped pressure seat 55 contacts the gear, when the telescopic pressure rod 37 continues to move downward, the first sliding pin 41 will enter the inner wall of the long vertical groove 43. At this time, the first sliding pin 41 no longer moves inward, that is, the corresponding long connecting plate 40 and positioning clamp rod 51 no longer move inward.

[0050] Two square sliders 50 are slidably connected to the inner end faces of the two long connecting plates 40. The positioning clamps 51 are fixed to the lower ends of the corresponding square sliders 50. Limiting plates 45 are fixed to the front and rear sides of the inner end face of the frame 38. Double-headed telescopic pins 46 are slidably connected to the inner walls of the limiting plates 45. The square sliders 50 are slidably connected to the sides of the corresponding double-headed telescopic pins 46. Two second track frames 47 are also fixed to the outer surface of the outer cylinder 52. The inner walls of the second track frames 47 are provided with short vertical grooves 48 and long inclined grooves 49 that cooperate with the double-headed telescopic pins 46.

[0051] like Figures 11-13 As shown, the square slider 50 can slide back and forth on the inner wall of the long connecting plate 40, meaning the limiting positioning rod 51 can only move back and forth on the long connecting plate 40; the limiting plate 45 provides limiting support for the double-headed telescopic pin 46, allowing the double-headed telescopic pin 46 to move only back and forth; both ends of the double-headed telescopic pin 46 can extend and retract, meaning that when the long connecting plate 40, square slider 50, etc., move inward or outward, they can always maintain connection with the double-headed telescopic pin 46. When the double-headed telescopic pin 46 moves to both sides, it can drive the square slider 50 and the positioning rod 51 to move to both sides. The movements of these components do not affect each other and can always maintain a connection; when the telescopic pressure rod 37 and the second track frame 47 move downwards, the double-headed telescopic pin 46 will not move due to the engagement of the short vertical groove 48 and the double-headed telescopic pin 46. When the telescopic pressure rod 37 and the second track frame 47 move downwards to the point that the double-headed telescopic pin 46 enters the inner wall of the long inclined groove 49, the telescopic pressure rod 37 and the second track frame 47 continue to move downwards, which will cause the double-headed telescopic pin 46, the square slider 50, the positioning clamp 51, etc. to move synchronously to both sides, thereby causing the positioning clamp 51 to move away from the gear; through the first sliding pin 4 With the cooperation of the first track frame 42, the second sliding pin, and the second track frame 47, when the telescopic pressure rod 37 moves downward, it can drive the two positioning clamping rods 51 to move inward under the engagement of the first sliding pin 41 and the short inclined groove 44. When the positioning clamping rods 51 move inward, they can clamp and position the gear. The second sliding pin will not drive the positioning clamping rods 51 to move under the engagement of the short vertical groove 48. Even if the positioning clamping rods 51 are in the innermost end state, when the telescopic pressure rod 37 moves downward to make the arc-shaped pressure seat 55 contact the gear and continues to move downward, this... When the first sliding pin 41 enters the inner wall of the long vertical groove 43, the positioning clamp 51 no longer moves inward. The second sliding pin enters the inner wall of the long inclined groove 49, which allows the positioning clamp 51 to move to both sides, that is, the positioning clamp 51 moves away from the gear. When the telescopic pressure rod 37 moves down to the bottom, the arc-shaped pressure seat 55 completely presses and fixes the gear. The two positioning clamps 51 move outward to the top position. At this time, the cutting tool can cut the gear. When the telescopic pressure rod 37 moves up to reset, the corresponding positioning clamp 51 can move outward to reset to the initial position. This will not be described in detail.

[0052] In use, when the drive plate 14 moves backward to a designated position, even when the material support 16 moves to the lower end of the stop gate 24, the stop gate 24 can flip downward and open, allowing the gear to fall into the material support 16 under gravity. When the drive plate 14 moves forward, the material support 16 supports the gear and moves forward. After the material support 16 moves forward to a designated position, the telescopic pressure rod 37, through the provided fixing device, can drive the arc-shaped pressure seat 55 downward when it moves downward, and can also cause the positioning clamping rod 51 to move inward. When the positioning clamping rod 51 moves inward, it can clamp and position the gear on the material support 16, placing the gear in the designated position on the material support 16, thus making the machining and cutting more precise. When the telescopic pressure rod 37 continues to move downward, it can bring the arc-shaped pressure seat 55 into contact with the gear. When the telescopic pressure rod 37 continues to move downward, the arc-shaped pressure seat 55 can squeeze the gear, thereby fixing the gear. At the same time, the positioning clamping rod 51 can move to both sides. The positioning clamp 51, located away from the arc-shaped pressure seat 55, the material support seat 16, and gears, provides operating space for gear cutting when it moves outward. After fixing the gear, the two drive motors 3 are controlled to move inward to cut the gear. After the gear is cut, the drive plate 14 is controlled to move forward. When the drive plate 14 moves forward to the designated position, the material support seat 16 flips downward to let the gear fall into the unloading trough 56. Guided by the unloading trough 56, the gear flows into the designated position for centralized collection. Through the automatic loading and unloading function, the inefficient and error-prone manual operation is completely eliminated, greatly improving production efficiency and meeting the needs of large-scale industrial production. The integrated design combines the loading and unloading with the chamfering process, simplifying the process, reducing the equipment footprint, and reducing the risk of errors caused by material transfer. At the same time, it ensures high-precision processing, effectively improves gear meshing performance, reduces operating noise, ensures the stability of the gear transmission system, and reduces the enterprise's safety production management costs.
