Description
Technical Field
[0001] The utility model relates to the technical field of hobbing racks, in particular to an adjustable hobbing rack of a planetary reducer with an inner gear ring. Background Art
[0002] Gear hobbing is the process of machining a pair of wheels with a hob, which is equivalent to a pair of staggered spiral wheels meshing. When the hob rotates one circle, the rack moves one tooth in the opposite direction. When the hob and the hob blank mesh strictly according to the transmission ratio, the hob teeth form tooth shapes at a series of positions. With the vertical feed of the hob, the required tooth profile can be rolled out. Gear hobbing is a process of machining gears based on the principle of the generation method. Using a hob to machine a pair of wheels is equivalent to the meshing of a helical cylindrical gear pair.
[0003] When the existing hobbing rack is used in conjunction with a processing device, there will be some deviations over time during use. For precision machining parts, the error between the machining device and the hobbing rack needs to be smaller. The position of the hobbing rack needs to be checked regularly and the hobbing rack needs to be adjusted to correct its position to improve machining accuracy.
[0004] Therefore, we propose an adjustable hobbing rack for a planetary reducer with an inner gear ring that can adjust the position of the hobbing rack to improve the processing accuracy and minimize the error of the processed product. Utility Model Content

[0009] Preferably, the limit block is slidably arranged inside the limit groove, and the sliding groove opened on the outer wall of the hobbing rack body is slidably arranged on the outer wall of the sleeve plate. When the limit block and the limit groove slide laterally, the inner wall of the limit groove opened on the outer wall of the hobbing rack body can be pushed by the limit block, so that the sliding groove opened on the outer wall of the hobbing rack body slides on the outer wall of the sleeve plate, so as to adjust the hobbing rack body laterally.
[0010] Preferably, the longitudinal threaded rod and the internal threaded strip of the sleeve plate, the interior of the sleeve plate and the outer wall of the limit rod are slidably arranged, so that when the longitudinal threaded rod rotates, the limit work can be performed under the restriction of the sliding of the limit rod and the sleeve plate.
[0011] Preferably, the telescopic rod is hingedly connected to the top surface of the base plate, and one end of the telescopic rod away from the top surface of the base plate is hingedly connected to the bottom of the mounting plate. Under its restriction, the mounting plate can be lifted up when the telescopic rod is working, so that the hobbing rack body is in an inclined state.
[0012] Preferably, there are two telescopic rods, which are symmetrically distributed about the center line of the top surface of the bottom plate, and are used to drive the hobbing rack body to move stably so that it is in an inclined state.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The adjustable hobbing rack of the planetary reducer of the inner gear ring is composed of an adjustment component. When the hobbing rack body is in use, it will produce some deviations. At this time, it needs to be adjusted. The transverse threaded rod can be rotated. Since the sleeve plate and the hobbing rack body are slidably arranged inside, and the limit block and the outer wall of the transverse threaded rod are threadedly sleeved, under its restriction, the rotating transverse threaded rod can drive the limit block to move horizontally. Since the limit block and the limit groove are longitudinally slidable, the limit block can drive the hobbing rack body to move horizontally through the limit groove, so that the inside of the hobbing rack body The inner wall of the sliding groove slides with the outer wall of the sleeve plate to adjust the gear rack body laterally. When the gear rack body needs to be adjusted longitudinally, the longitudinal threaded rod can be rotated. Since the inside of the sleeve plate and the outer wall of the limit rod are slidingly arranged, and the outer wall of the longitudinal threaded rod is sleeved with the inner thread of the sleeve plate, under its restriction, when the longitudinal threaded rod rotates, it can drive the sleeve plate to move longitudinally, so that the gear rack body slidingly arranged on the outer wall of the sleeve plate can move longitudinally. This structure can fine-tune the gear rack body that has been used for a long time, so that the gear rack body can operate more precisely.
[0015] 2. The adjustable hobbed rack of the planetary reducer of the inner gear ring is composed of a tilt assembly as one of its components. When the hobbed rack body is in use and its tilt angle needs to be adjusted, the telescopic rod can be started. Since the telescopic rod is hingedly connected to the top surface of the base plate, and its end away from the top surface of the base plate is hingedly connected to the hinge block fixedly installed on the bottom of the mounting plate through the fixed block, under its restriction, the telescopic rod can move the top surface of the mounting plate when working. Since the mounting plate is hingedly connected to the fixed plate, the mounting plate drives the hobbed rack body to tilt, so as to achieve the effect of adjusting the tilt of the hobbed rack body.

DETAILED DESCRIPTION
[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.
[0024] Example 1
[0025] The preferred embodiment of the adjustable hobbing rack of the planetary reducer with an inner gear ring provided by the utility model is as follows: Figures 1 to 6 Shown: An adjustable hobbed rack of a planetary reducer with an internal gear ring, including a base plate 1;
[0026] A mounting plate 2 is provided above the bottom plate 1;
[0027] A hobbing rack body 3 is arranged above the mounting plate 2;
[0028] And a processing component 4 is arranged above the base plate 1, the processing component 4 includes an adjusting component 41 arranged above the base plate 1, the adjusting component 41 includes a vertical plate 418 fixedly installed on the top surface of the mounting plate 2, a longitudinal threaded rod 411 is connected inside the vertical plate 418, a sleeve plate 412 is sleeved on the outer wall of the longitudinal threaded rod 411, a limit rod 413 is slidably arranged inside the sleeve plate 412, a limit groove 414 is arranged on the outer wall of the hobbing rack body 3, a limit block 415 is slidably arranged inside the limit groove 414, a transverse threaded rod 416 is sleeved inside the limit block 415, and a sliding groove 417 is arranged on the outer wall of the hobbing rack body 3.
[0029] In this embodiment, when the hobbing rack body 3 is in use, it will produce some deviations. At this time, it needs to be adjusted. The transverse threaded rod 416 can be rotated. Since the sleeve plate 412 is slidably arranged inside the hobbing rack body 3, and the limit block 415 is threadedly sleeved on the outer wall of the transverse threaded rod 416, under its restriction, the rotating transverse threaded rod 416 can drive the limit block 415 to move horizontally. Since the limit block 415 and the limit groove 414 are longitudinally slidable, the limit block 415 can drive the hobbing rack body 3 to move horizontally through the limit groove 414, so that the inner wall of the slide groove 417 opened in the hobbing rack body 3 and the sleeve plate 4 12 outer wall slides to adjust the gear rack body 3 laterally. When the gear rack body 3 needs to be adjusted longitudinally, the longitudinal threaded rod 411 can be rotated. Since the interior of the sleeve plate 412 is slidably arranged with the outer wall of the limit rod 413, and the outer wall of the longitudinal threaded rod 411 is threadedly sleeved with the interior of the sleeve plate 412, under its restriction, when the longitudinal threaded rod 411 is rotated, the sleeve plate 412 can be driven to move longitudinally, so that the gear rack body 3 with the sliding outer wall of the sleeve plate 412 can move longitudinally. This structure can fine-tune the gear rack body 3 that has been used for a long time, so that the gear rack body 3 can operate more precisely.
[0030] Furthermore, the limit block 415 is slidably arranged inside the limit groove 414, and the slide groove 417 opened on the outer wall of the hobbing rack body 3 is slidably arranged on the outer wall of the sleeve 412. When the limit block 415 and the limit groove 414 slide laterally, the limit block 415 can push the inner wall of the limit groove 414 opened on the outer wall of the hobbing rack body 3, so that the slide groove 417 opened on the outer wall of the hobbing rack body 3 slides on the outer wall of the sleeve 412, so as to adjust the hobbing rack body 3 laterally.
[0031] Furthermore, the longitudinal threaded rod 411 and the internal threaded strip of the sleeve plate 412, the interior of the sleeve plate 412 and the outer wall of the limiting rod 413 are slidingly arranged, so that when the longitudinal threaded rod 411 rotates, the limiting work can be performed under the restriction of the sliding of the limiting rod 413 and the sleeve plate 412.

[0034] In this embodiment, when the hobbing rack body 3 is in use and its inclination angle needs to be adjusted, the telescopic rod 422 can be started. Since the telescopic rod 422 is hingedly connected to the top surface of the base plate 1, and its end away from the top surface of the base plate 1 is hingedly connected to the hinge block 424 fixedly installed at the bottom of the mounting plate 2 through the fixed block 423, under its restriction, the telescopic rod 422 can move the top surface of the mounting plate 2 when working. Since the mounting plate 2 is hingedly connected to the fixed plate 421, the mounting plate 2 drives the hobbing rack body 3 to tilt, so as to achieve the effect of adjusting the inclination of the hobbing rack body 3.
[0035] Furthermore, the telescopic rod 422 is hingedly connected to the top surface of the base plate 1, and one end of the telescopic rod 422 away from the top surface of the base plate 1 is hingedly connected to the bottom of the mounting plate 2. Under its restriction, the telescopic rod 422 can lift the mounting plate 2 when working, so that the hobbing rack body 3 is in an inclined state.
[0036] In addition, there are two telescopic rods 422, which are symmetrically distributed with respect to the center line of the top surface of the bottom plate 1, and are used to drive the hobbing rack body 3 to move stably so as to make it in an inclined state.
