Description

Technical Field

[0001] This utility model relates to the field of bearing processing technology, specifically to an installation and positioning device for rolling bearings. Background Technology

[0002] As is well known, in the field of mechanical manufacturing, rolling bearings are key transmission components, and their installation accuracy directly affects the operational stability, transmission efficiency and service life of equipment. In order to ensure that the inner ring and outer ring of the bearing achieve a precise interference fit or transition fit, and to avoid damage to the bearing raceway and rolling elements or loss of geometric accuracy due to uneven force during installation, various installation and positioning devices are widely used in the bearing assembly process.

[0003] In existing technologies, the mounting and positioning devices for rolling bearings are typically designed for specific bearing specifications. Their structural dimensions, positioning references, and force points are strictly matched with parameters such as the inner ring diameter, outer ring diameter, and width of the target bearing. However, this one-to-one design mode requires replacing the entire mounting and positioning device to adapt to the new bearing parameters when different specifications (such as different diameters and widths) of rolling bearings need to be assembled. This not only increases the purchase cost and storage space of the equipment but also prolongs the changeover time in the production process. In multi-variety, small-batch production scenarios, frequent replacement of the positioning device can lead to a significant reduction in production efficiency, and multiple disassembly and adjustment can easily introduce positioning errors, affecting the consistency of bearing installation accuracy. Summary of the Invention

[0004] Technical problems to be solved In order to overcome the problem that the bearing specifications installed by existing rolling bearing mounting and positioning devices are fixed, this utility model provides a rolling bearing mounting and positioning device that can install bearings of different specifications.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] See Figures 1-6A rolling bearing mounting and positioning device includes a body 1, which serves as the outer shell of the device. An internal movable groove 8 is provided within the body 1, housing a drive assembly 3 and two sets of adjusting assemblies 2. Multiple sliding grooves 9 are provided on the top of the body 1, and these grooves communicate with the movable groove 8. Two sets of first clamping blocks 4 and two sets of second clamping blocks 5 are slidably connected to the top of the body 1. Both the first clamping blocks 4 and the second clamping blocks 5 are arc-shaped, and the second clamping blocks 5 are larger than the first clamping blocks 4. Connecting rods 7 are fixedly connected to the bottom of both the first clamping blocks 4 and the second clamping blocks 5. The connecting rods 7 are installed by welding or bolting, and are slidably connected within the sliding grooves 9. The bottom end of the connecting rod 7 extends into the movable groove 8 and is fixedly connected to one side of the adjusting assembly 2. A positioning post 6 is welded to the top of the body 1, and the positioning post 6 is located between the two sets of first clamping blocks 4.

[0018] First, refer to Figures 2 to 5 In this embodiment, the adjustment component 2 includes a horizontal plate 201 and a placement frame 208. The horizontal plate 201 is rectangular, and the placement frame 208 is concave. The horizontal plate 201 is slidably connected in the movable groove 8, and the placement frame 208 is welded to the inner wall of the movable groove 8. A support seat 205 is welded to one side of the horizontal plate 201, and multiple sets of connecting rods 7 are welded to one side of the support seat 205. The support seat 205 is used to support the connecting rods 7, the first clamping block 4, and the second clamping block 5. The displacement of the support seat 205 will drive the first clamping block 4 and the second clamping block 5 to move by driving the multiple sets of connecting rods 7. Two sets of protrusions 207 are welded to the side of the placement frame 208 near the horizontal plate 201. The protrusions 207 are semi-elliptical protrusions. The inner wall of the horizontal plate 201... A balance bar 213 is welded to the part, and a push plate 209 is slidably connected to the outside of the balance bar 213. A slider 206 is slidably connected to the outside of the push plate 209. The slider 206 is rectangular and is used to support the push plate 209. When the slider 206 moves, it will drive the push plate 209 to move. One side of the slider 206 is fixedly connected to one side of the drive assembly 3. A central shaft 212 is welded to both sides of the push plate 209. A pulley 210 is rotatably connected to the outside of the central shaft 212. The central shaft 212 is used to support the pulley 210. When the pulley 210 moves, it will push the push plate 209 to move by pushing the central shaft 212. The outside of the pulley 210 is in contact with one side of the protrusion 207.

[0019] Specifically, in order to enable the support seat 205 to move back quickly, two sets of fixing plates 203 are welded to the inner wall of the movable groove 8. A first spring 204 is welded between the fixing plate 203 and the support seat 205. Thus, when the support seat 205 is pushed, the first spring 204 will be squeezed by the support seat 205. When the support seat 205 is no longer pushed, the first spring 204 will bounce the first clamping block 4 and the second clamping block 5 back by bouncing the support seat 205 back.

[0020] Meanwhile, in order to maintain the balance of the horizontal plate 201 during movement, two sets of limiting rods 202 are welded on one side of the horizontal plate 201, and the end of the limiting rod 202 away from the horizontal plate 201 is slidably connected to the inside of the fixed plate 203. Thus, the movement of the horizontal plate 201 will be restricted by the limiting rods 202. On the one hand, the limiting rods 202 maintain the balance of the horizontal plate 201 during movement, preventing the horizontal plate 201 from becoming unbalanced and swaying during movement, and ensuring the normal displacement of the horizontal plate 201. On the other hand, the limiting rods 202 restrict the direction of the horizontal plate 201, preventing the device from failing due to the misalignment of the horizontal plate 201, and ensuring the normal use of the device.

[0021] Specifically, in order to prevent the pulley 210 from detaching from the central shaft 212, a baffle plate 211 is welded on the outside of the central shaft 212. The baffle plate 211 is circular and located on the side of the pulley 210 away from the push plate 209. Thus, the baffle plate 211 can block the pulley 210 and prevent the pulley 210 from detaching from the central shaft 212.

[0022] Specifically, in order to enable the push plate 209 to move back quickly, a second spring 214 is welded inside the push plate 209. The end of the second spring 214 away from the push plate 209 is welded inside the slider 206. Thus, when the push plate 209 is pushed, the second spring 214 will be stretched by the push plate 209, and when the push plate 209 is no longer pushed, the second spring 214 will bounce the push plate 209 back to its initial position quickly.

[0023] When slider 206 is pushed, slider 206 will drive push plate 209 to move. The displacement of push plate 209 will drive pulley 210 to move by driving central shaft 212. During the movement, pulley 210 will be pushed by protrusion 207 to move towards horizontal plate 201. The movement of pulley 210 will drive push plate 209 to move by driving central shaft 212. The movement of push plate 209 will drive balance bar 213 to move. The movement of balance bar 213 will drive horizontal plate 201 to move. The movement of horizontal plate 201 will drive support seat 205 to move. The movement of support seat 205 will drive first clamping block 4 and second clamping block 5 to move by driving multiple sets of connecting rods 7. This changes the position of first clamping block 4 and second clamping block 5, so that the device can be adapted to the positioning and installation of different bearings.

[0024] Finally, see Figure 2 and Figure 6In this embodiment, the drive assembly 3 includes a rotary motor 301, which is disposed inside the body 1. The rotary motor 301 is selected from the first forward and reverse motor in CN223014108U, and its output end can rotate forward or reverse. The output end of the rotary motor 301 is key-connected to a threaded tube 305. A sleeve 302 is screwed onto the outside of the threaded tube 305. A threaded hole is opened inside the sleeve 302, and the thread on the inner wall of the threaded hole is adapted to the thread on the outside of the threaded tube 305. When the threaded tube 305 rotates, it will drive the sleeve 302 to move linearly. A mounting plate 30 is welded to the outside of the sleeve 302. 3. A connecting plate 304 is welded to the side of the mounting plate 303 away from the sleeve 302. The connecting plate 304 is rectangular, and two sets of sliders 206 are fixedly installed on both sides of the connecting plate 304. The connecting plate 304 is used to drive the two sets of sliders 206 to move. After the rotary motor 301 is turned on, the output end of the rotary motor 301 will drive the threaded tube 305 to rotate. The rotation of the threaded tube 305 will drive the sleeve 302 to move linearly. The displacement of the sleeve 302 will drive the mounting plate 303 to move. The movement of the mounting plate 303 will drive the connecting plate 304 to move. The movement of the connecting plate 304 will push the sliders 206 to move.

[0025] The rolling bearing mounting and positioning device uses the cooperation between pulley 210 and protrusion 207. When pulley 210 is displaced, it will be pushed by protrusion 207 to move towards horizontal plate 201. The movement of pulley 210 will drive push plate 209 to move. The movement of push plate 209 will push support base 205 by pushing horizontal plate 201. This will cause support base 205 to drive first clamping block 4 and second clamping block 5 to move. The movement of first clamping block 4 and second clamping block 5 changes the installation specifications of the device, enabling the device to position and install bearings of different specifications.

[0026] Working principle: The rolling bearing uses a mounting and positioning device. In use, first, place the rolling bearing in the desired position using the mounting and positioning device. Then, adjust the positions of the first clamping block 4 and the second clamping block 5. Specifically, the operation is as follows: Turn on the rotary motor 301 so that its output end drives the threaded tube 305 to rotate. The rotation of the threaded tube 305 will cause the sleeve 302 to move linearly. The displacement of the sleeve 302 will cause the mounting plate 303 to move. The movement of the mounting plate 303 will cause the connecting plate 304 to move. The movement of the connecting plate 304 will push the slider 206 to move. When the slider 206 is pushed, it will cause the push plate 209 to move. The displacement of the push plate 209 will then drive the intermediate... The spindle 212 drives the pulley 210 to move. During the movement, the pulley 210 will be pushed by the protrusion 207 to move towards the horizontal plate 201. The movement of the pulley 210 will drive the push plate 209 to move by driving the central spindle 212. The movement of the push plate 209 will drive the balance bar 213 to move. The movement of the balance bar 213 will drive the horizontal plate 201 to move. The movement of the horizontal plate 201 will drive the support 205 to move. The movement of the support 205 will drive the first clamping block 4 and the second clamping block 5 to move by driving multiple sets of connecting rods 7. This changes the position of the first clamping block 4 and the second clamping block 5, so that the device can be adapted to the positioning and installation of different bearings.
