A fixed bearing base for a ball screw

Abstract

This invention provides a fixed bearing base for a ball screw, including a lower arc-shaped mounting base and an upper arc-shaped mounting base. Connecting plates are fixedly mounted on the top of both sides of the lower arc-shaped mounting base, and each of the connecting plates has a first adjusting component on its top. This invention controls the movement of the first adjusting block by driving the first threaded rods on both sides, thereby causing the upper arc-shaped mounting base to move up and down. This allows the groove inside the upper arc-shaped mounting base to make tight contact with and fix the top of the ball screw bearing. When the diameter of the ball screw bearing is small and further fixing with a second adjusting block is required, the second threaded rod is rotated to control the second adjusting block to move downwards until it contacts and fixes the bearing top. This improves the versatility of the device, reduces problems such as insecure fixing or excessive compression caused by differences in bearing diameter, thereby extending the service life of the bearing and reducing equipment maintenance costs.

Description

Technical Field

[0001] This utility model mainly relates to the field of fixed bearing technology, specifically a fixed bearing base for a ball screw. Background Technology

[0002] A fixed bearing is a type of bearing used in mechanical devices to fix a shaft or components mounted on it. Its main function is to restrict the axial and radial movement of the shaft or its components, ensuring positional stability and accuracy during operation. Examples include motors, speed reducers, and machine tools; it is a crucial component ensuring the normal operation of the equipment.

[0003] In the existing technology, the fixed bearing base lacks adjustability and cannot adapt to ball screw bearings of different diameters. As a result, when facing bearings of different specifications, the fixing device may not be able to provide tight contact and stable fixation, thereby affecting the operating stability and service life of the bearing. Utility Model Content

[0004] This utility model mainly provides a fixed bearing base for ball screws to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A fixed bearing base for a ball screw includes a lower arc-shaped mounting base and an upper arc-shaped mounting base. Connecting plates are fixedly mounted on the top of both sides of the lower arc-shaped mounting base, and a first adjustment component is provided on the top of both connecting plates.

[0007] The upper arc-shaped mounting base has a placement groove on its top surface, and a second adjustment component is provided on the top of the upper arc-shaped mounting base.

[0008] Preferably, the first adjustment component includes a first mounting bracket, a first threaded rod, and a first adjustment block. The top of each of the two connecting plates is fixedly mounted with a first mounting bracket, and the bottom wall of each of the two first mounting brackets is connected to a first threaded rod via a rotating shaft. The outer side of one end of each of the two first threaded rods is threadedly connected to a first adjustment block, and one side of each of the two first adjustment blocks is fixedly connected to both sides of the upper arc-shaped mounting base.

[0009] Preferably, the second adjustment component includes a second mounting bracket, a connecting hole, a second threaded rod, and a second adjustment block. The second mounting bracket is fixedly mounted on the top of the upper arc-shaped mounting base, and a connecting hole is opened on the top surface of the second mounting bracket. The second threaded rod is threadedly connected inside the connecting hole. The bottom of the second threaded rod is connected to the second adjustment block through a rotating shaft, and the second adjustment block is placed inside the placement slot when not in use.

[0010] Preferably, both ends of the first adjusting block are connected to limit rods through through holes, and the two limit rods are respectively fixedly connected to the two ends inside the first mounting bracket.

[0011] Preferably, a limiting plate is connected between the inner walls on both sides of the second mounting bracket, and the center of the limiting plate is threadedly connected to the second threaded rod through a mounting hole.

[0012] Preferably, fixing blocks are fixedly installed on both sides of the lower arc-shaped mounting base, and fixing holes are opened on one side of the top of the two fixing blocks.

[0013] Preferably, the tops of both first threaded rods are connected to a rotating block passing through the top of the first mounting bracket.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By driving the first threaded rods on both sides, the movement of the first adjusting block is controlled, which in turn drives the upper arc-shaped mounting seat to move up and down. This allows the groove inside the upper arc-shaped mounting seat to make tight contact with and fix the top of the ball screw bearing. When the diameter of the ball screw bearing is small and further fixing is required using the second adjusting block, the second threaded rod is rotated to control the second adjusting block to move downward until it contacts the top of the bearing and completes the fixing. This improves the versatility of the device, reduces problems such as insecure fixing or excessive compression caused by differences in bearing diameter, thereby extending the service life of the bearing and reducing the maintenance cost of the equipment.

[0016] 2. When the second adjusting block is not needed, it can be stored in the placement slot by rotating the second threaded rod in the opposite direction, thus avoiding interference between the second adjusting block and other components.

[0017] The present invention will be explained in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0023] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive. Example

[0024] Please refer to the appendix carefully. Figure 1-4A fixed bearing base for a ball screw includes a lower arc-shaped mounting base 1 and an upper arc-shaped mounting base 2, both made of 42CrMo4 material, heat-treated and tempered, possessing high strength, toughness, and good hardenability, exhibiting excellent performance under high loads and complex working conditions. Connecting plates 3 are fixedly mounted on the top of both sides of the lower arc-shaped mounting base 1, and each of the two connecting plates 3 has a first adjusting component 4 on its top. The first adjusting component 4 includes a first mounting bracket 401, a first threaded rod 402, and a first adjusting block 403. The first mounting bracket 401 is fixedly mounted on the top of both connecting plates 3, and the inner bottom wall of each of the two first mounting brackets 401 is connected to the first threaded rod 402 via a rotating shaft. The outer side of one end of each of the two first threaded rods 402 is threadedly connected to the first adjusting block 4. 03, and the two first adjusting blocks 403 are fixedly connected to the two sides of the upper arc-shaped mounting base 2 on one side respectively. The first mounting bracket 401 provides the mounting base for the first threaded rod 402. The threaded connection between the first threaded rod 402 and the first adjusting block 403 realizes the adjustment function. The first adjusting block 403 is fixedly connected to the upper arc-shaped mounting base 2 to ensure that the adjustment action can be transmitted to the upper arc-shaped mounting base 2, thereby realizing the fixation of the ball screw bearing. Both ends of the first adjusting block 403 are connected to limit rods 7 through through holes, and the two limit rods 7 are fixedly connected to the two ends inside the first mounting bracket 401 on the other side respectively. The setting of the limit rods 7 further restricts the movement direction of the first adjusting block 403, so that it can only move in a straight line along a predetermined trajectory, improving To ensure the accuracy and stability of the adjustment, the tops of both first threaded rods 402 are connected to rotating blocks 12 that pass through the top of the first mounting bracket 401. The rotating blocks 12 facilitate the operator's rotation of the first threaded rods 402, making the adjustment process more convenient. The top surface of the upper arc-shaped mounting base 2 has a placement groove 5, and the top of the upper arc-shaped mounting base 2 is equipped with a second adjustment component 6. The second adjustment component 6 includes a second mounting bracket 601, a connecting hole 602, a second threaded rod 603, and a second adjustment block 604. The second mounting bracket 601 is fixedly mounted on the top of the upper arc-shaped mounting base 2, and the top surface of the second mounting bracket 601 has a connecting hole 602. The second threaded rod 603 is threadedly connected inside the connecting hole 602, and the bottom of the second threaded rod 603 passes through... A second adjusting block 604 is connected via a rotating shaft. A second mounting bracket 601 provides an installation position for the second threaded rod 603. A connecting hole 602 allows the second threaded rod 603 to be threadedly connected to the second mounting bracket 601. The rotating shaft connection between the second threaded rod 603 and the second adjusting block 604 allows the second adjusting block 604 to move up and down as the second threaded rod 603 rotates, thereby further fixing the ball screw bearing. When not in use, the second adjusting block 604 is placed inside the placement groove 5. A limiting plate 8 is connected between the inner walls of both sides of the second mounting bracket 601, and the center of the limiting plate 8 is threadedly connected to the second threaded rod 603 through a mounting hole 9. The limiting plate 8 and the mounting hole 9 restrict the movement direction of the second threaded rod 603.This allows it to move only vertically up and down. Fixing blocks 10 are fixedly installed on both sides of the lower arc-shaped mounting base 1, and each fixing block 10 has a fixing hole 11 on one side of its top. Bolts are used to connect the fixing blocks 10 to the external structure through the fixing holes 11.

[0025] The specific operation method of this utility model is as follows:

[0026] In use, the ball screw bearing is placed inside the groove of the lower arc-shaped mounting base 1. The first threaded rods 402 on both sides are driven to move the first adjusting block 403, thereby moving the upper arc-shaped mounting base 2 until the groove inside the upper arc-shaped mounting base 2 contacts and fixes the top of the ball screw bearing. When the diameter of the ball screw bearing is smaller than the diameter of the groove of the lower arc-shaped mounting base 1, the second threaded rod 603 is rotated to move the second adjusting block 604 downward until the second adjusting block 604 contacts and fixes the top of the ball screw bearing. At the same time, when the second adjusting block 604 is not needed, the second threaded rod 603 is rotated in the opposite direction to move the second adjusting block 604 into the placement groove 5 to avoid structural interference and not affect the fixation of the ball screw bearing.

[0027] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
