Description

Technical Field

[0001] The utility model relates to the technical field of worm gear box press-fitting, in particular to a worm gear box press-fitting device. Background Art

[0002] The worm gear box, that is, the worm reducer, is also known as the worm gear reducer or worm gear reducer and worm gear reducer. It is mainly composed of a worm wheel or gear, a shaft, a bearing and a chassis, and the worm wheel or gear, shaft and bearing are supported by the chassis. Therefore, the reducer chassis shell must have sufficient hardness to avoid deformation after loading, thereby causing a decrease in transmission quality. The worm gear reducer is widely used because of its durability, large transmission ratio, small size, strong self-locking ability, simple structure and easy manufacturing. However, its transmission efficiency is relatively low. When assembling the worm gear box, the bearing needs to be pressed into the mounting hole of the worm gear box.

[0003] For example, a worm gear case press-fitting device disclosed in Chinese patent CN217193750U, when in use, the worm gear case fixing assembly fixes and clamps the worm gear case, places the bearing in the receiving groove, so that the clamping assembly fixes the bearing, and the adjusting assembly moves the press-fitting table so that the bearing and the mounting hole of the worm gear case are arranged concentrically, the second telescopic cylinder extends, and the second telescopic cylinder pushes the press-fitting slider to move to the left through the press-fitting plate until the press-fitting slider contacts the worm gear case, the second telescopic cylinder continues to extend, and the second telescopic cylinder pushes the press-fitting plate to move to the left, and the press-fitting plate presses the bearing into the mounting hole of the worm gear case, and by continuing to fix the worm gear case and the bearing, and adjusting the concentricity of the worm gear case and the bearing, the press-fitting accuracy and efficiency are improved.

[0004] For this structure, although the bearing and the inside of the worm gear box can be press-fitted, the device clamps the bearing through the receiving groove. Since the sizes of the bearings are different, it is inconvenient to press-fit the bearing and the worm gear box through the receiving groove. Therefore, we propose a worm gear box press-fitting device that can clamp bearings of different sizes to expand the application range of the press-fitting device. Utility Model Content

[0005] The purpose of the utility model is to provide a worm gear box press-fitting device to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a worm gear box press-fitting device, comprising a press-fitting table, a support leg fixedly installed at the bottom of the press-fitting table, a press-fitting table vertical plate, a worm gear box housing arranged above the press-fitting table, a mounting column fixedly installed on the inner wall of the worm gear box housing, a bearing sleeve on the outer wall of the mounting column, and a processing assembly arranged on the top surface of the press-fitting table, the processing assembly including a press-fitting assembly arranged on the top surface of the press-fitting table, and a clamping assembly arranged on the left side of the press-fitting assembly.

[0007] Preferably, the pressing assembly includes a cylinder fixedly mounted on the top surface of the pressing table, an L-shaped plate fixedly mounted on the end of the cylinder, a slide fixedly mounted on the outer wall of the L-shaped plate, a slide rail slidably arranged on the outer wall of the slide, a sleeve fixedly mounted on the side of the L-shaped plate away from the cylinder, a first screw is sleeved inside the sleeve, a swivel is sleeved on the outer wall of the first screw, a push block is rotatably connected to the end of the first screw away from the sleeve, a connecting plate is hingedly connected to the outer wall of the push block, an anti-skid plate is hingedly connected to the end of the connecting plate away from the push block, a limiting rod is fixedly mounted on the outer wall of the anti-skid plate, and a limiting ring is slidably arranged on the outer wall of the limiting rod.

[0008] Preferably, the clamping assembly includes a conveying rod fixedly mounted on the top surface of the press-fitting table, a receiving plate is fixedly mounted on one end of the conveying rod away from the top surface of the press-fitting table, a fixing plate is fixedly mounted on one end of the receiving plate away from the conveying rod, a second screw is sleeved inside the fixing plate, and the end of the second screw is rotatably connected to a clamping arc plate.

[0009] Preferably, there are six anti-skid plates distributed around the center of the first screw rod. The outer wall of the anti-skid plate is set in an arc-shaped L-shape. The anti-skid plate is made of anti-slip material. The anti-skid plate used for the arc-shaped setting can fit more closely with the outer wall of the bearing. Under the action of the L-shaped setting of the anti-skid plate, the cylinder can press the bearing and the mounting column more firmly. The anti-skid plate made of anti-slip material can prevent sliding during the clamping process of the bearing to improve the stability of the clamping.

[0010] Preferably, the slide rail is fixedly mounted on the top surface of the press-fitting table, and the L-shaped plate is fixedly mounted on the outer wall of the limiting ring, so that when the L-shaped plate is pushed by the cylinder, the bearing clamped inside the limiting ring is driven to move accordingly.

[0011] Preferably, there are two clamping arc plates, which are slidably arranged with the outer wall of the vertical plate. The clamping arc plates are arranged in an arc shape, and are used to more closely clamp the worm gear box housing with the arc-shaped outer wall. When the clamping arc plates slide with the outer wall of the vertical plate, the second screw rotates, which can push the clamping arc plates to move toward the worm gear box housing.

[0012] Preferably, the outer wall of the receiving plate and the outer wall of the vertical plate are slidably arranged, one end of the conveying rod is fixedly installed on the bottom of the receiving plate, and the end of the conveying rod away from the receiving plate is fixedly installed on the top surface of the pressing table. When it is necessary to align and adjust the clamped worm gear box shell with the bearing center, starting the conveying rod can push the clamped worm gear box shell to move.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The worm gear box press-fitting device is composed of a press-fitting assembly as one of its components. When it is necessary to press-fit the mounting column fixedly mounted on the inner wall of the worm gear box housing, the bearing needs to be clamped first, the bearing is placed inside the limit ring, and the swivel is rotated so that the swivel drives the first screw sleeved inside it to rotate, so that the first screw moves inside the sleeve, so that the first screw drives the push block connected to its end to move in the direction of the sleeve, so that the connecting plate hingedly connected to the outer wall of the push block pulls it away from the anti-slide plate hingedly connected to one end of the push block, so that the six anti-slide plates clamp the outer wall of the bearing, and the anti-slide plates are on the outer wall of the anti-slide plate. Under the restriction of the sliding of the fixed limit rod and the limit ring, the anti-skid plate can be stably clamped with the outer wall of the bearing. At this time, the cylinder is started to push the sleeve toward the vertical plate, so that the sleeve drives it to move away from the bearing arranged at one end of the L-shaped plate, so that the slide fixedly installed on the outer wall of the L-shaped plate slides inside the slide rail fixedly installed on the top surface of the pressing table to press the bearing and the mounting column. Since the outer wall of the anti-skid plate is L-shaped, under its restriction, the cylinder can press the bearing and the mounting column more firmly, avoiding the damage of the outer wall of the bearing caused by the friction between the anti-skid plate and the outer wall of the bearing, so as to ensure the precision of the worm gear box.

[0015] 2. The worm gear box press-fitting device is composed of a clamping assembly as one component. When the worm gear box housing and the bearing need to be press-fitted, the worm gear box housing needs to be clamped first, and the worm gear box housing is placed on the top surface of the receiving plate, and the second screw is rotated. Since the outer wall of the clamping arc plate and the outer wall of the vertical plate are slidingly arranged, under the restriction of the second screw, when the second screw rotates, the two clamping arc plates can clamp the outer wall of the worm gear box housing. When the mounting column fixedly installed on the inner wall of the worm gear box housing is not aligned with the center of the bearing, the conveying rod is started to lift the clamped bearing, and then the two second screws are adjusted to align the mounting column fixedly installed on the inner wall of the worm gear box housing with the center of the bearing, so that the bearing and the mounting column can be pressed more accurately.

[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. Example 1

[0028] A mounting column 5 is fixedly mounted on the inner wall of the worm gear housing 4;

[0029] The outer wall of the mounting column 5 is sleeved with a bearing 6;

[0030] and a processing assembly 7 arranged on the top surface of the press-fitting platform 1, the processing assembly 7 includes a press-fitting assembly 71 arranged on the top surface of the press-fitting platform 1, the press-fitting assembly 71 includes a cylinder 711 fixedly installed on the top surface of the press-fitting platform 1, an L-shaped plate 712 is fixedly installed on the end of the cylinder 711, a slide 713 is fixedly installed on the outer wall of the L-shaped plate 712, a slide rail 714 is slidably arranged on the outer wall of the slide 713, and a sleeve 715 is fixedly installed on the side of the L-shaped plate 712 away from the cylinder 711 A first screw rod 716 is sleeved inside the sleeve 715, and a swivel 717 is sleeved on the outer wall of the first screw rod 716. The end of the first screw rod 716 away from the sleeve 715 is rotatably connected to a push block 718. The outer wall of the push block 718 is hingedly connected to a connecting plate 719. The end of the connecting plate 719 away from the push block 718 is hingedly connected to an anti-skid plate 720. A limiting rod 721 is fixedly installed on the outer wall of the anti-skid plate 720, and a limiting ring 722 is slidably provided on the outer wall of the limiting rod 721.

[0031] The first and second screw rods 716 are pressed together to form a circle 722, and the first and second screw rods 716 are pressed together to form a circle 722. The first and second screw rods 716 are pressed together to form a circle 722. The first and second screw rods 716 are pressed together to form a circle 722. Under the restriction of sliding of the positioning rod 721 and the limiting ring 722, the anti-skid plate 720 can be stably clamped with the outer wall of the bearing 6. At this time, the cylinder 711 is started to push the sleeve 715 toward the direction of the vertical plate 3, so that the sleeve 715 drives it to move away from the bearing 6 set at one end of the L-shaped plate 712, so that the slide 713 fixedly installed on the outer wall of the L-shaped plate 712 slides inside the slide rail 714 fixedly installed on the top surface of the pressing table 1 to press the bearing 6 and the mounting column 5. Since the outer wall of the anti-skid plate 720 is set in an L shape, under its restriction, the cylinder 711 can press the bearing 6 and the mounting column 5 more firmly, avoiding the friction between the anti-skid plate 720 and the outer wall of the bearing 6 causing damage to the outer wall of the bearing 6, so as to ensure the precision of the worm gear box.

[0032] Furthermore, there are six anti-skid plates 720, which are distributed around the center of the first screw rod 716. The outer wall of the anti-skid plate 720 is set in an arc-shaped L shape. The anti-skid plate 720 is made of anti-slip material. The anti-skid plate 720 used for the arc-shaped setting can fit more closely with the outer wall of the bearing 6. Under the action of the L-shaped setting of the anti-skid plate 720, the cylinder 711 can press the bearing 6 and the mounting column 5 more firmly. The anti-skid plate 720 made of anti-slip material can prevent the bearing 6 from sliding during the clamping process to improve the stability of the clamping.

[0033] Furthermore, the slide rail 714 is fixedly installed on the top surface of the press-fitting table 1, and the L-shaped plate 712 is fixedly installed on the outer wall of the limiting ring 722, so that when the L-shaped plate 712 is pushed by the cylinder 711, the bearing 6 clamped inside the limiting ring 722 is driven to move accordingly. Example 2

[0034] On the basis of Example 1, a preferred embodiment of a worm gear housing press-fitting device provided by the present invention is as follows: Figures 1 to 6 As shown: the clamping assembly 73 includes a conveying rod 731 fixedly installed on the top surface of the press-fitting table 1, a receiving plate 732 is fixedly installed on one end of the conveying rod 731 away from the top surface of the press-fitting table 1, and a fixing plate 733 is fixedly installed on one end of the receiving plate 732 away from the conveying rod 731, and a second screw 734 is sleeved inside the fixing plate 733, and the end of the second screw 734 is rotatably connected to a clamping arc plate 735.

[0035] In this embodiment, when it is necessary to press-fit the worm gear box housing 4 and the bearing 6, it is necessary to clamp the worm gear box housing 4 first, place the worm gear box housing 4 on the top surface of the receiving plate 732, and rotate the second screw 734. Since the outer wall of the clamping arc plate 735 is slidably arranged with the outer wall of the vertical plate 3, under its restriction, when the second screw 734 rotates, the two clamping arc plates 735 can clamp the outer wall of the worm gear box housing 4. When the mounting column 5 fixedly installed on the inner wall of the worm gear box housing 4 is not aligned with the center of the bearing 6, the conveying rod 731 is started to lift the clamped bearing 6, and then the two second screws 734 are adjusted to align the mounting column 5 fixedly installed on the inner wall of the worm gear box housing 4 with the center of the bearing 6, so that the pressing of the bearing 6 and the mounting column 5 is more accurate.

[0036] Going a step further, there are two clamping arc plates 735, which are slidably arranged with the outer wall of the vertical plate 3. The clamping arc plates 735 are arranged in an arc shape, and are used to clamp the worm gear box housing 4 with the arc-shaped outer wall more closely. Under the action of the sliding of the clamping arc plates 735 and the outer wall of the vertical plate 3, when the second screw 734 rotates, the clamping arc plates 735 can be pushed to move toward the worm gear box housing 4.

[0037] In addition, the outer wall of the receiving plate 732 and the outer wall of the vertical plate 3 are slidably arranged, one end of the conveying rod 731 is fixedly installed on the bottom of the receiving plate 732, and the end of the conveying rod 731 away from the receiving plate 732 is fixedly installed on the top surface of the pressing table 1. When it is necessary to align and adjust the center of the clamped worm gear box housing 4 and the bearing 6, starting the conveying rod 731 can push the clamped worm gear box housing 4 to move.
