Description

Technical Field

[0001] This invention relates to the field of machining technology, and specifically to a planetary gear housing machining device. Background Technology

[0002] A planetary gear reducer is a mechanical speed reduction device that can achieve a wide range of speed ratio and torque changes in a small space, thereby improving mechanical transmission efficiency. A planetary gear reducer includes multiple planetary gears, a sun gear, a planet carrier, and a planetary gear housing. The planetary gears mesh with the sun gear, and the planet carrier is connected to the planetary gears and the sun gear respectively. The inner wall of the planetary gear housing is provided with an internal gear ring that can mesh with the planetary gears.

[0003] Currently, when machining the internal gear ring of a planetary gear housing, the planetary gear housing is usually placed on a base. A limiting plate, which is rotatably connected to a support column located on the base and distributed circumferentially, abuts against the upper surface of the planetary gear housing. The limiting plate is bolted to the base, and its position is fixed. The limiting plate limits the planetary gear housing, and the cutting tool then extends into the inner wall of the planetary gear housing to machine the internal gear ring.

[0004] However, currently, the process involves placing the planetary gear housing on the base, then manually rotating the limiting plate to place it on the planetary gear housing, and finally connecting the limiting plate to the base. The base then limits the position of the limiting plate, and the limiting plate limits the position of the planetary gear housing, making the operation quite cumbersome. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a planetary gear housing processing device that can automatically limit the planetary gear housing and also stably limit the planetary gear housings of different specifications.

[0006] The technical solution adopted in this invention is as follows: A planetary gear housing processing device includes a base and a plurality of support seats circumferentially arranged on the base. The support seats are provided with a first moving component for driving a limiting component to move along the Z direction. The first moving component is provided with a second moving component for driving the limiting component to move along the X direction. The second moving component is provided with a limiting component for limiting the planetary gear housing. The limiting component includes a first limiting part and a second limiting part. When the first limiting part abuts against the side wall of the planetary gear housing, the second limiting part moves along the X direction and abuts against the upper surface of the planetary gear housing. The base, the first limiting part and the second limiting part cooperate to limit the planetary gear housing vertically and circumferentially.

[0007] The principle of the technical solution:

[0008] The planetary gear housing is placed on the base. The first moving component moves along the Z direction, making the lower end face of the second limiting part coplanar with the upper surface of the planetary gear housing. The second moving component moves along the X direction, making the end face of the first limiting part abut against the planetary gear housing. The second moving component continues to move along the X direction, and the side wall of the planetary gear housing abuts against the end face of the first limiting part. The second limiting part abuts against the upper surface of the planetary gear housing. The second moving component stops moving. The second limiting part and the base cooperate to limit the upper and lower movement of the planetary gear housing. Since the base is provided with multiple support seats, each support seat is provided with a first moving component, a second moving component, and a limiting component. That is, the planetary gear housing is provided with multiple second limiting parts in the circumferential direction. The multiple second limiting parts cooperate to limit the circumferential movement of the planetary gear housing.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] The first moving component, the second moving component, and the limiting component of this invention work together to automatically limit the movement of planetary gear housings of different specifications. Operation is convenient. The first moving component can adjust the position of the limiting component in the Z direction, thus matching the height of the planetary gear. Conventional limiting plates have non-adjustable lengths and can only limit the vertical movement of the planetary gear housing. When the limiting plate abuts against the upper surface of the planetary gear housing, a single type of limiting plate can only provide limiting for planetary gear housings of a corresponding thickness. When limiting planetary gear housings of different thicknesses is required, the corresponding limiting plate needs to be replaced. The second moving component, the first limiting part, and the second limiting part of this invention work together to provide stable limiting for planetary gear housings of different thicknesses, with a wide range of applications, ensuring consistent vertical and circumferential limiting of the planetary gear housing.

[0011] In a preferred embodiment of the present invention, the limiting component further includes a connecting cylinder, a moving block, and a first spring located inside the connecting cylinder. The second moving component includes a power source, and the connecting cylinder is connected to the power source. One end of the first limiting part and the second limiting part both pass through the connecting cylinder and are flush. The outer surface of the end of the first limiting part located inside the connecting cylinder is an inwardly concave slope. The moving block is slidably engaged with the slope of the first limiting part and the inner wall of the connecting cylinder. The slope of the moving block is slidably engaged with the second limiting part. Both ends of the first spring are respectively connected to the inner wall of the connecting cylinder and the first limiting part. When the first limiting part abuts against the side wall of the planetary gear housing, the first limiting part moves inward toward the connecting cylinder along the X direction, and the second limiting part moves outward toward the connecting cylinder along the X direction and abuts against the upper end of the planetary gear housing.

[0012] In this design, the side wall of the planetary gear housing abuts against the first limiting part. The first limiting part moves into the connecting cylinder along the X direction. Since the inclined surface of the first limiting part slides with the moving block, and the moving block slides with the inner wall of the connecting cylinder, when the first limiting part moves into the connecting cylinder along the X direction, the first spring is compressed, and the moving block moves along the Z direction. Since the inclined surface of the moving block slides with the second limiting part, one end of the second limiting part is located outside the connecting cylinder. When the moving block moves along the Z direction, the second limiting part slides with the inclined surface of the moving block, and one end of the second limiting part moves outward along the X direction and abuts against the upper surface of the planetary gear housing. This achieves the upper and lower limiting of the planetary gear housing by the cooperation of the second limiting part and the base, and the limiting of the side wall of the planetary gear housing by the cooperation of multiple first limiting parts.

[0013] Beneficial effects: The connecting cylinder, the first limiting part, the first spring, the moving block, and the second limiting part work together to achieve the action of the first limiting part on the side wall of the planetary gear housing, thereby enabling the second limiting part to move automatically in the X direction. Moreover, since the first limiting part tends to move outward from the connecting cylinder and return to its initial position under the elastic force of the first spring, the first limiting part always exerts a squeezing force on the side wall of the planetary gear housing, ensuring that the connecting cylinder stably abuts against the side wall of the planetary gear housing, thereby enhancing the limiting of the planetary gear housing.

[0014] In a preferred embodiment of the present invention, the second limiting part is provided with a first connecting component, the first connecting component includes a first roller and a first connecting part, the first roller is slidably engaged with the inclined surface of the moving block, the two ends of the first connecting part are respectively rotatably connected to the first roller and fixedly connected to the second limiting part, and a second spring is connected between the first connecting part and the inner wall of the connecting cylinder.

[0015] In this design, when the moving block moves upward along the Z direction, the inclined surface of the moving block slides with the first roller, the second spring is compressed, and the second limiting part moves outward along the X direction through the first roller and the first connecting part, realizing the automatic movement of the second limiting part along the X direction. The second limiting part abuts against the upper surface of the planetary gear housing. When the first limiting part does not abut against the side wall of the planetary gear housing, the second spring, under the action of elastic force, drives the first connecting part and the first roller back to the initial position, the moving block moves downward along the Z direction, and the first connecting part drives the second limiting part back to the initial position.

[0016] Beneficial effects: The inclined surface of the moving block, the first roller, and the first connecting part work together to enable the second limiting part to move automatically in the X direction. With the addition of the second spring, the second limiting part can automatically return to the initial position, thus achieving automatic and stable limiting of the planetary gear housing.

[0017] In a preferred embodiment of the present invention, the movable block abuts against one end of the first limiting part located inside the connecting cylinder.

[0018] Beneficial effects: The first limiting part provides support for the moving block, ensuring that the moving block can move stably along the Z direction, thereby ensuring that the inclined surface of the moving block and the second limiting part slide stably together, and the second limiting part moves stably and automatically along the X direction and automatically returns to the initial position.

[0019] In a preferred embodiment of the present invention, the lower end of the moving block is symmetrically provided with retractable telescopic rods that are connected to the inner wall of the bottom of the connecting cylinder, and the two telescopic rods are respectively located on both sides of the first spring.

[0020] Beneficial effects: The telescopic rod provides support for the moving block, further improving the stability of the moving block's movement along the height direction of the connecting cylinder, ensuring stable sliding cooperation between the inclined surface of the moving block and the second limiting part, and the second limiting part moves stably and automatically along the X direction and automatically returns to the initial position.

[0021] In a preferred embodiment of the present invention, the lower end of the movable block is provided with a second connecting component. The second connecting component includes a second roller and a second connecting part. The second roller is slidably engaged with the inclined surface of the first limiting part. Both the inclined surface of the first limiting part and the inclined surface of the movable block are provided with grooves. The inner surface of the bottom of the groove is parallel to the corresponding inclined surface of the first limiting part and the inclined surface of the movable block. The first roller and the second roller are both located in the corresponding grooves and are slidably engaged with the corresponding grooves. The two ends of the second connecting part are rotatably connected to the second roller and fixedly connected to the movable block, respectively.

[0022] Beneficial effects: The groove can limit the first roller and the second roller, ensuring stable sliding cooperation between the first roller and the inclined surface of the moving block, and between the second roller and the inclined surface of the first limiting part.

[0023] In a preferred embodiment of the present invention, the support base includes a first support portion and a second support portion connected to the first support portion. The second support portion is provided with a slide rail. The first moving component includes a motor, a lead screw connected to the motor, and a first slider that slides with the lead screw. The motor is connected to the second support portion, one end of the lead screw is connected to the first support portion, and the slide rail is slidably fitted with the second slider. A first connecting plate is connected between the first slider and the second slider. One end of the first connecting plate is connected to the second connecting plate, and the second connecting plate is connected to a power source. The movable end of the power source is provided with a limiting component for limiting the planetary gear housing.

[0024] Beneficial effects: The second support can provide support for the motor. The slide rail and the second slider work together to ensure that the first connecting plate moves stably in the Z direction, thereby ensuring that the first moving component and the limiting component move stably in the Z direction.

The two ends of the spring 405 are respectively connected to the inner wall of the connecting cylinder 403 and the first limiting part 401. The two telescopic rods 6 are respectively located on both sides of the first spring 405. The lower end of the moving block 404 is provided with a second connecting component 7. The second connecting component 7 includes a second roller 701 and a second connecting part 702. The second roller 701 is slidably engaged with the inclined surface of the first limiting part 401.

[0044] The inclined surface of the movable block 404 is slidably engaged with the second limiting part 402. The second limiting part 402 is provided with a first connecting component 5.

[0047] In this embodiment, the motor 201, lead screw 202, first slider 203, first connecting plate 204, and second connecting plate 205 cooperate to drive the limiting component 4 to move along the Z direction, thereby providing a limit for planetary gear housings of different heights. The slide rail 103 and second slider 104 cooperate to ensure stable movement of the limiting component 4 along the Z direction. The power source 301 and third connecting part cooperate to drive the limiting component 4 to move along the X direction, thereby providing a limit for planetary gear housings of different thicknesses. The first limiting part 401 and the second limiting part 402 cooperate to accurately provide vertical and circumferential limiting for the planetary gear housing. When the first limiting part 401 abuts against the side wall of the planetary gear housing, the motor 201 and power source 301 on the circumferentially distributed support 1 start simultaneously. The corresponding multiple first limiting parts 401 can also automatically calibrate the position of the planetary gear housing to ensure that the axis of the planetary gear housing is located at the center of the base, so that the distance between the cutting edge of the tool and the outer edge of the planetary gear housing is equal everywhere, thereby improving the machining accuracy of the internal gear.

[0048] Specific limiting process during planetary gear housing machining:

[0049] The planetary gear housing is placed on the base. The motor 201 starts and drives the lead screw 202 to rotate. The rotation of the lead screw 202 drives the first slider 203 to slide along the Z direction. The first slider 203 drives the first connecting plate 204 to move along the Z direction. At the same time, the first slider 203 drives the second slider 104 to slide and engage with the slide rail 103 through the first connecting plate 204. The first connecting plate 204 moves stably along the Z direction. The first connecting plate 204 drives the second moving component and the limiting component 4 to move along the Z direction through the second connecting plate 205. When the lower end face of the second limiting part 402 is coplanar with the upper surface of the planetary gear housing, the motor 201 stops starting.

[0050] Then, the power source 301 is started, and the movable end of the power source 301 moves along the X direction. The connecting cylinder 403 approaches the side wall of the planetary gear housing, and the first limiting part 401 abuts against the side wall of the planetary gear housing. Multiple first limiting parts 401 abut against the side wall of the planetary gear housing at the same time, automatically calibrating the position of the planetary gear housing to ensure that the axis of the planetary gear housing is located at the center of the base. At this time, the outer ends of the first limiting part 401 and the outer ends of the second limiting part 402 are aligned.

[0051] As the power source 301 continues to move along the X direction, the planetary gear housing abuts against the first pressing block in the first limiting part 401, pushing the first pressing block to move inward toward the connecting cylinder 403 along the X direction. Since the second pressing block in the first limiting part 401 is connected to the first spring 405, and the other end of the first spring 405 is connected to the inner wall of the connecting cylinder 403, when the first pressing block moves into the connecting cylinder 403, it drives the second pressing block to move into the connecting cylinder 403, compressing the first spring 405. Since the inclined surface of the second pressing block and the moving block 404 are in sliding engagement through the second roller 701, when the second pressing block moves into the connecting cylinder 403, it drives the moving block 404 to move inward along the Z direction. As the moving block 404 moves upward, it slides against the inner wall of the connecting cylinder 403. Since the inclined surface of the moving block 404 slides against the second limiting part 402 through the first roller 501, when the moving block 404 moves upward along the Z direction, the moving block 404 drives the second limiting part 402 to move outward along the X direction through the first roller 501 and the first connecting part 502. The second spring 503 is compressed, and the second limiting part 402 automatically moves along the X direction and abuts against the upper surface of the planetary gear housing. The second limiting part 402 and the base cooperate to limit the upper and lower positions of the planetary gear housing. Multiple first limiting parts 401 cooperate to limit the side wall of the planetary gear, and the planetary gear housing begins to be processed.

[0052] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
