Description

Technical Field

[0001] The utility model belongs to the field of planetary frame processing, in particular to a fast positioning tool for processing a planetary frame. Background Art

[0002] The planet carrier is a key component in the planetary gear transmission. It needs to be able to withstand various forces and torques from the engine, road conditions and transmission. In order to realize the use of the planet carrier, the planet carrier needs to be clamped.

[0003] In a Chinese patent with publication number CN219944691 U, a planetary carrier processing and positioning tool is mentioned, including a base, a plurality of fixed seats are fixedly connected to the base, and a positioning groove for inserting the planetary carrier is opened on the fixed seat. The base is also provided with a plurality of drive components corresponding to the fixed seats, and a pressure plate is provided on the drive component. By setting the fixed seat and the angle cylinder, a pressure plate is set on the driving shaft of the angle cylinder, and the angle rod drives the pressure plate to rotate and press down. When putting in and taking out the planetary carrier, the pressure plate can rotate, reducing interference with the putting in and taking out of the planetary carrier, and the automatic drive means that workers only need to perform pick-and-place operations, thereby improving processing efficiency.

[0004] However, under the action of the corner rod driving pressure plate, the size of the planetary carrier that can be positioned is limited, resulting in the inability of the positioning tool to clamp different types of planetary carriers. At the same time, the planetary carrier cannot rotate as a whole when clamped by the positioning tool, causing limitations in the processing of the planetary carrier.

[0005] To this end, those skilled in the art have proposed a rapid positioning tool for machining a planet carrier to solve the problems raised in the background art. Utility Model Content

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] As attached Figure 1 To Attachment Figure 4 As shown:

[0026] Embodiment 1: The utility model provides a quick positioning tool for processing a planetary carrier, including a base 1, a support plate 2 arranged on the top of the base 1, a screw 3 arranged in the support plate 2, an adjustment mechanism 4 arranged on the top of the base 1, and a clamping mechanism 5 arranged on the top of the adjustment mechanism 4.

[0027] Furthermore, the clamping mechanism 5 includes a connecting plate 501, a connecting rod 503 arranged in the connecting plate 501, a fixing ring 502 arranged outside the connecting rod 503, a limiting rod 505 arranged in the connecting rod 503, a bearing 508 arranged on the side wall of the fixing ring 502, a sleeve 507 arranged on the side wall of the bearing 508, a spring 506 arranged in the sleeve 507, and a fixing plate 504 arranged at one end of the spring 506.

[0028] Furthermore, the connecting rod 503 is provided with several groups, and the connecting rod 503 is slidably connected to the inside of the connecting plate 501. The fixing ring 502 is provided with several groups, and the fixing ring 502 is slidably connected to the inside of the connecting rod 503. The side wall of the bearing 508 is rotatably connected to the side wall of the fixing ring 502. The side wall of the sleeve 507 is clamped on the side wall of the bearing 508. One end of the spring 506 is fixed to the inside of the sleeve 507. The fixing plate 504 is fixed to the inside of the sleeve 507 through the spring 506.

[0029] Furthermore, the adjustment mechanism 4 includes a support column 401, a limit plate 403 arranged on the top of the support column 401, a rack 404 arranged in the support column 401, a baffle 402 arranged in the support column 401, a fixed seat 407 arranged in the support column 401, a gear 406 arranged on the side wall of the fixed seat 407, and a support plate 405 arranged on the side wall of the rack 404.

[0030] Furthermore, the side wall of the fixed seat 407 is fixedly connected to the inside of the support column 401, the side wall of the gear 406 is rotatably connected to the side wall of the fixed seat 407, the side wall gear of the rack 404 is meshed with the side wall of the gear 406, the side wall of the support plate 405 is slidably connected to the inside of the baffle 402, the bottom of the limit plate 403 is fixedly connected to the top of the support column 401, and the side wall of the rack 404 is clamped on the side wall of the limit plate 403.

[0031] Furthermore, two groups of the support plates 2 are provided, and the two groups of the support plates 2 are slidably connected to the inside of the base 1 , and the bottom of the screw 3 is threadedly connected to the inside of the support plate 2 .

[0032] As can be seen from the above, by rotating the connecting rod 503, the outer part of the connecting rod 503 is inside the connecting plate 501, and when the connecting rod 503 moves, the sleeve 507 is driven to move synchronously, and the planet carrier to be processed is placed on the top of the connecting plate 501. By pushing the connecting rod 503, the side wall of the connecting rod 503 is inside the connecting plate 501, and the bottom of the connecting rod 503 slides inside the supporting plate 405. By moving multiple groups of connecting rods 503, the side wall of the fixing plate 504 contacts the side wall of the planet carrier. It is worth noting that the multiple sets of fixing plates 504 are in a mutually clamped state, so that the planet carrier is fixed to the side wall of the fixing plate 504 as a whole, so as to avoid the planet carrier from being offset. When the planet carrier needs to be flipped, the gear meshing between the rack 404 and the gear 406 is used to make the rack 404 move and drive the gear 406 to rotate, and by pulling the rack 404 to move upward, the rack 404 drives the support plate 405 to move upward as a whole. At the same time, when the support plate 405 moves upward, the support plate 405 is also One side slides inside the baffle 402, so that the support plate 405 is more stable when moving as a whole. At the same time, when the rack 404 moves, the side wall of the rack 404 contacts the side wall of the limit plate 403, and the limit plate 403 is used to limit the position of the rack 404. When the rack 404 moves to a suitable position, the limit rod 505 is pushed and the connecting rod 503 is pulled at the same time, so that the limit rod 505 pushes the fixing plate 504 to move, and the spring 506 is in a stretched state, so that the connecting rods on both sides of the planet carrier 503 and the fixing plate 504 contact the side wall of the planet carrier. By rotating the planet carrier, the planet carrier drives the fixing plate 504 and the sleeve 507 to rotate synchronously. The bearing 508 between the sleeve 507 and the fixing ring 502 is used to realize the overall rotation of the planet carrier. When the planet carrier itself is large in size, the limiting rod 505 is pulled to disengage the limiting rod 505 from the inside of the connecting rod 503 and the sleeve 507. By pushing one side of the fixing ring 503 downward, the fixing effect of planet carriers of different sizes is achieved.

[0034] As can be seen from the above, when the fixing ring 502 needs to be replaced, the limiting rod 505 is pulled to move the limiting rod 505 and the bearing 508 out of the interior of the connecting rod 503, so that the bearing 508 and the sleeve 507 are away from one side of the connecting rod 503, and the bearing 508 is rotated in the opposite direction to separate the bearing 508 and the fixing ring 502. The fixing ring 502 is pulled to separate from the outside of the connecting rod 503, and the limiting rod 505 is pushed to fix the sleeve 507 on the side wall of the fixing ring 502, thereby achieving the replacement effect of the fixing ring 502.
