Description

Technical Field

[0001] This application relates to the field of gear processing technology, specifically a gear chamfering processing device. Background Technology

[0002] A gear chamfer refers to machining a circular bevel on the tooth surface of a gear. Its purpose is to reduce the impact and noise during gear meshing, and to increase the smoothness and lifespan of the transmission. Specifically, a chamfer makes the switching between two gears smoother, thereby extending the service life of the gears and improving the convenience of operation.

[0003] An existing patent (publication number: CN210550035U) discloses a gear chamfering processing device, which is equipped with a pressing component. The pressing component can be pressed down by the action of a tension spring to press and fix the gear. The pressing component can be moved up by the action of a second cylinder to release the gear. In this way, the present invention can press or release the gear by moving the pressing component up and down, so that the operator does not need to frequently tighten and loosen bolts to fix the gear, reducing the workload of the operator and improving work efficiency.

[0004] While the devices described in the aforementioned comparative documents can reduce the workload of operators, the existing devices have a fixed chamfering head height. When chamfering gears of different thicknesses, it is inconvenient to adjust the chamfering head height. Furthermore, the chamfering head angle cannot be adjusted, and the chamfering can only be performed at a fixed angle. This cannot ensure that the chamfering head contacts the gear at the optimal angle, and it cannot meet diverse processing needs. To solve the above problems, a gear arc chamfering processing device is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a gear chamfering device, which facilitates chamfering of gears of different thicknesses and supports chamfering at different angles to meet diverse processing needs. Furthermore, by adjusting the angle, it ensures that the chamfering head contacts the gear at the optimal angle, reducing errors and improving chamfering accuracy.

[0006] To achieve the above objectives, this application provides the following technical solution: a gear chamfering processing device, comprising a base, a lifting device, a chamfering mechanism, a rotating mechanism, and a connecting column. The lifting device is disposed on the upper end of the base, the chamfering mechanism is disposed on the right end of the lifting device, the rotating mechanism passes through the upper end of the base, and the connecting column is disposed on the upper end of the rotating mechanism. The lifting device includes a lifting platform, and a transmission chamber is formed inside the lifting platform. A first forward and reverse motor is fixedly connected inside the transmission chamber. A threaded column is fixedly connected to the upper end of the output shaft of the first forward and reverse motor. A threaded tube is threadedly connected to the upper end of the threaded column. A slider is fixedly connected to the side of the threaded tube. A sliding groove is formed inside the transmission chamber, and the slider is slidably connected inside the sliding groove. A fixing block is fixedly connected to the upper end of the threaded tube. The angle mechanism includes a second forward and reverse motor, which is fixedly connected to the right side of the fixed block. A first fixed disk is fixedly connected to the right end of the second forward and reverse motor. A fixed rod is fixedly connected to the middle of the right outer wall of the first fixed disk. A second rotating ball is fixedly connected to the right end of the fixed rod. A rectangularly distributed ball seat is fixedly connected to the right outer wall of the first fixed disk. The first rotating ball is rotatably connected inside the ball seat. A first electric push rod is fixedly connected to the outer wall of the first rotating ball. A U-shaped seat is movably connected to one end of the piston rod of the first electric push rod. A second fixed disk is fixedly connected to the right end of the U-shaped seat. The second fixed disk and the second rotating ball form a rotational engagement. A motor is fixedly connected to the middle of the right outer wall of the second fixed disk. A chamfered head is fixedly connected to the right end of the output shaft of the motor.

[0007] The above scheme, by setting up a lifting mechanism and a chamfering mechanism, allows the operator to control the operation of the first forward and reverse motors, thereby driving the threaded column to rotate. With the cooperation of the threaded column and the threaded tube, the chamfering mechanism moves up and down, facilitating the chamfering of gears of different thicknesses. The operator controls the extension and retraction of the four first electric push rods, which allows the second fixed disc to rotate around the second rotating ball, enabling multi-directional adjustment of the chamfering head. The second forward and reverse motors can drive the chamfering head to rotate and adjust, allowing for multi-directional adjustment of the chamfering head, thus supporting chamfering processing at different angles and meeting diverse processing needs. Furthermore, by adjusting the angle, it is ensured that the chamfering head contacts the gear at the optimal angle, reducing errors and improving chamfering accuracy.

[0008] Furthermore, the rotating mechanism includes a fixed seat, which is installed on the upper end of the base. A third forward and reverse motor is fixedly connected inside the fixed seat. A rotating shaft is fixedly connected to the upper end of the output shaft of the third forward and reverse motor. A bearing is installed on the upper surface of the fixed seat. The rotating shaft is installed inside the bearing. A turntable is fixedly connected to the upper end of the rotating shaft. The connecting column is fixedly connected to the upper end of the turntable.

[0009] The above scheme controls the operation of the third forward and reverse motors, which in turn drive the turntable to rotate at a certain angle. When the turntable rotates, it drives the gear to rotate synchronously, which facilitates the chamfering of the other tooth of the gear.

[0010] Furthermore, a first slide rail is provided on the upper surface of the fixed base, and a second slide rail is provided on the lower surface of the turntable. Ball bearings are rotatably connected inside the first and second slide rails. There are multiple sets of ball bearings, which are symmetrically arranged inside the first and second slide rails.

[0011] The above solution, through the cooperation of the first slide rail, the second slide rail, and the ball bearings, prevents the turntable from tilting during rotation.

[0012] Furthermore, the base has a cavity inside, and a second electric push rod is fixedly connected inside the cavity.

[0013] The above scheme allows for easy adjustment of the pressing component to a suitable height by controlling the operation of the second electric push rod.

[0014] Furthermore, a connector is fixedly connected to the upper end of the second electric push rod, and a pressing component is provided at the left end of the connector.

[0015] The above solution facilitates the chamfering of the gear by using the pressing component.

[0016] Furthermore, the pressing component has internal threaded bolts, and the pressing component is fixedly connected by bolts and connectors.

[0017] With the above scheme, the pressing component and the connecting component are detachably connected. The pressing component is horizontally set and is semi-circular. The size of the pressing component is adapted to the size of the gear to be processed. The pressing component is symmetrically set about the axis of the connecting column. In this way, when the pressing component presses down and fixes the gear placed on the turntable, the contact area between the pressing component and the gear is large, so that the gear is pressed more firmly.

[0018] Furthermore, a cylinder is fixedly connected to the upper end of the base, a sliding block is fixedly connected to the right end of the cylinder, and the lifting platform is located on the upper end of the sliding block.

[0019] With the above scheme, the cylinder pushes the sliding block to move so that the chamfering head is close to the gear, making it easier to adjust the left and right position of the chamfering head.

[0020] Furthermore, a protective layer is provided on the inner side and lower end of the pressing component.

[0021] The above solution uses a protective layer to prevent damage to the gears from the pressing components.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This gear chamfering processing device, through the setting of a lifting mechanism and a chamfering mechanism, allows the operator to control the operation of the first forward and reverse motors, thereby driving the threaded column to rotate. With the cooperation of the threaded column and the threaded tube, the chamfering mechanism moves up and down, facilitating the chamfering of gears of different thicknesses. The operator controls the extension and retraction of the four first electric push rods, which allows the second fixed plate to rotate around the second rotating ball, thus enabling multi-directional adjustment of the chamfering head. The second forward and reverse motors can drive the chamfering head to rotate and adjust, allowing for multi-directional adjustment of the chamfering head, supporting chamfering processing at different angles, meeting diverse processing needs, and ensuring that the chamfering head contacts the gear at the optimal angle by adjusting the angle, reducing errors and improving chamfering accuracy.

With the cooperation of the threaded tube 205, the chamfering mechanism 4 is driven to move up and down, which facilitates the chamfering of gears of different thicknesses. The operator controls the extension and retraction of the four first electric push rods 405, which allows the second fixed plate 407 to rotate around the second rotating ball 409, thereby enabling the chamfering head 411 to be adjusted in multiple directions. The second forward and reverse motor 401 can drive the chamfering head 411 to rotate and adjust, which allows the chamfering head 411 to be adjusted in multiple directions, thus supporting chamfering processing at different angles and meeting diverse processing needs.

There are multiple sets of rolling balls 507, which are symmetrically arranged inside the first slide rail 505 and the second slide rail 506. By controlling the operation of the third forward and reverse motor 502, the turntable 508 is driven to rotate at a certain angle.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 6 The base 1 has a cavity 7 inside, and a second electric push rod 8 is fixedly connected inside the cavity 7. A connector 9 is fixedly connected to the upper end of the second electric push rod 8. A pressing component 10 is provided at the left end of the connector 9. A bolt 11 is threaded inside the pressing component 10. The pressing component 10 is fixedly connected to the connector 9 by the bolt 11. A cylinder 12 is fixedly connected to the upper end of the base 1. A sliding block 13 is fixedly connected to the right end of the cylinder 12. A lifting platform 201 is located on the upper end of the sliding block 13. A protective layer 14 is provided on the inner side and lower end of the pressing component 10. By controlling the operation of the second electric push rod 8, the pressing component 10 can be easily adjusted to a suitable height. To facilitate the limiting chamfering of the gear, the pressing component 10 and the connecting component 9 are detachably connected. The pressing component 10 is horizontally arranged and is semi-circular. The size of the pressing component 10 is adapted to the size of the gear to be processed. The pressing component 10 is symmetrically arranged about the axis of the connecting column 6. In this way, when the pressing component 10 presses down and fixes the gear placed on the turntable 508, the contact area between the pressing component 10 and the gear is large, so that the gear is pressed more firmly. The cylinder 12 pushes the sliding block 13 to move so that the chamfering head 411 is close to the gear, which facilitates the adjustment of the left and right position of the chamfering head 411. The protective layer 14 prevents the pressing component 10 from damaging the gear.

[0036] In this embodiment, the gear chamfering processing device includes a lifting mechanism and a chamfering mechanism 4. The operator controls the operation of the first forward and reverse motor 203, which drives the threaded column 204 to rotate. With the cooperation of the threaded column 204 and the threaded tube 205, the chamfering mechanism 4 moves up and down, facilitating chamfering of gears of different thicknesses. The operator controls the extension and retraction of the four first electric push rods 405, allowing the second fixed plate 407 to rotate around the second rotating ball 409, thus enabling multi-directional adjustment of the chamfering head 411. The second forward and reverse motor 401 drives the chamfering head 411 to rotate and adjust, allowing for multi-directional adjustment of the chamfering head 411 to support chamfering at different angles, meeting diverse processing needs. Furthermore, by adjusting the angle, the chamfering head 411 is ensured to contact the gear at the optimal angle, reducing errors and improving chamfering accuracy.

[0037] The working principle of the above embodiment is as follows: When performing arc chamfering on the gear, the gear is fitted onto the connecting column 6 so that the gear is placed on the turntable 508. The second electric push rod 8 is controlled to operate, driving the pressing component 10 to move down and press the gear down and fix it on the turntable 508. The cylinder 12 is controlled to operate, and the cylinder 12 pushes the sliding block 13 to move so that the chamfering head 411 is close to the gear. The first forward and reverse motor 203 is controlled to operate, thereby driving the threaded column 204 to rotate. With the cooperation of the threaded column 204 and the threaded tube 205, the chamfering mechanism 4 is driven to move up and down. The chamfering mechanism 4 is adjusted to a suitable height according to the different thicknesses of the gear. The operator controls the four first electric push rods 405 to extend and retract respectively, so that the second fixed plate 407 can rotate around the second rotating ball 409, thereby... The chamfering head 411 is adjustable in multiple directions. The second forward and reverse motor 401 is controlled to drive the chamfering head 411 to rotate and adjust to a suitable position. Then, the motor 410 is controlled to perform arc chamfering. After one tooth of the gear is chamfered, the cylinder 12 retracts, causing the chamfering head 411 to move away from the gear. The second electric push rod 8 is controlled to move the pressing component 10 upward. The third forward and reverse motor 502 is controlled to move the turntable 508 to rotate at a certain angle. When the turntable 508 rotates, it drives the gear to rotate synchronously. After rotating to the correct position, the second electric push rod 8 is controlled to move the pressing component 10 to press the gear down and fix it. Then, the cylinder 12 works to bring the chamfering head 411 closer to the gear to chamfer the other tooth of the gear. This process is repeated to chamfer each tooth of the gear one by one.
