Description

Technical Field

[0001] This utility model relates to the field of lead screw support technology, specifically to an adjustable lead screw support support side. Background Technology

[0002] In modern industrial production, lead screw drive systems are widely used in machine tools, automated equipment, and precision machinery. As a core component, the installation accuracy of the lead screw directly affects the operating performance and service life of the equipment. However, in practical applications, due to manufacturing errors, assembly deviations, and wear caused by long-term use, the center heights of the fixed and supporting sides of the lead screw often do not match, resulting in the lead screw being in a partially horizontal state. This deviation leads to a decrease in the rigidity of the lead screw system, increased vibration, increased noise, and even affects the normal operation of the equipment.

[0003] Therefore, it is urgent to design an adjustable screw support side to solve the problem of inconsistent center height between the screw support side and the fixed side. Utility Model Content

[0004] The technical implementation scheme of this utility model is: an adjustable self-aligning screw support side, comprising:

[0005] Fixed block;

[0006] A first circular hole is formed on the fixed block and is used for the lead screw to pass through; a self-aligning block is disposed on one side of the fixed block and is used to adjust the center height of the lead screw;

[0007] The second circular hole is formed on the self-aligning block, and the bearing for mounting the lead screw is installed in the second circular hole;

[0008] The fixed block has a movable hole, which is formed in the circumference of the fixed block with the first circular hole as the center; and a first adjusting screw, which is movably disposed in the movable hole and threadedly connected to the self-aligning block, which is mounted on one side of the fixed block by the first adjusting screw.

[0009] Optionally, the fixing block has longitudinal through holes symmetrically opened on both sides of its first circular hole, and a second adjusting screw is installed in the through hole.

[0010] Optionally, the through hole is configured as a countersunk hole.

[0011] Optionally, a retaining ring for fixing the bearing to the screw is provided on the side facing away from the fixing block, and fixing holes are provided at both ends of the opening of the retaining ring.

[0012] Optionally, the bearing is a deep groove ball bearing.

[0013] Optionally, the diameter of the movable hole is larger than the diameter of the first adjusting screw.

[0014] Optionally, the diameter of the first circular hole is larger than the diameter of the second circular hole.

[0015] Optionally, the fixing block is configured as a convex structure.

[0016] Optionally, both the first adjusting screw and the second adjusting screw are hexagonal cylindrical screws.

[0017] Optionally, the retaining ring for the shaft is made of an elastic material.

[0018] The beneficial effects of this utility model are as follows: 1. By cooperating with the self-aligning block and the first adjusting screw, the center height of the lead screw support side can be flexibly adjusted to keep it consistent with the fixed side, effectively solving the problem of inconsistent center height caused by manufacturing errors or assembly deviations, and improving the rigidity and stability of the lead screw system.

[0019] 2. When there is a large difference in center height between the supporting side and the fixed side of the screw support, the height of the fixed block can be adjusted by the second adjusting screw in the movable hole, thereby adjusting the height of the self-aligning block. This facilitates the subsequent adjustment of the self-aligning block to make the center height of the fixed side and the supporting side of the screw support consistent. Attached Figure Description

Detailed Implementation

[0026] The present invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0027] Example 1: A self-aligning screw support side, such as Figures 1-5 As shown, the device includes a fixing block 1, which has a convex structure. The convex structure can more evenly distribute the load pressure, reduce local stress concentration, and prevent the material from deforming or being damaged due to long-term pressure. The fixing block 1 has a first circular hole 11 for the lead screw to pass through. A self-aligning block 2 is provided on one side of the fixing block 1, and the self-aligning block 2 has a second circular hole 21. The diameter of the first circular hole 11 is larger than the diameter of the second circular hole 21. A bearing for mounting the lead screw is installed in the second circular hole 21 of the self-aligning block 2. The bearing for mounting the lead screw is a deep groove ball bearing 3. It has the advantages of low friction coefficient and high limiting speed, making it suitable for high-speed rotation while reducing energy consumption and operating noise. The fixed block 1 has a transverse movable hole 4 circumferentially opened around its first circular hole 11. A first adjusting screw is movably installed in the movable hole 4. The diameter of the movable hole 4 is larger than the diameter of the first adjusting screw. This arrangement facilitates the movement and adjustment of the first adjusting screw in the movable hole 4, thereby adjusting the position of the self-aligning block 2. The first adjusting screw is a hexagonal cylindrical screw 5 and is threadedly connected to the self-aligning block 2. The self-aligning block 2 is installed on one side of the fixed block 1 by the first adjusting screw.

[0028] In use, first press the deep groove ball bearing 3 into the second round hole 21 of the self-aligning block 2, and connect the self-aligning block 2 to the fixed block 1 using the first adjusting screw; then, install the lead screw onto the fixed side and support side of the lead screw support, and use the shaft retaining ring 6 to lock the lead screw in place to fix the position of the support side, thus confirming the position where the lead screw passes through the deep groove ball bearing 3; then, check the center height of the fixed side and support side of the lead screw support, and adjust the height of the self-aligning block 2 so that the center height of the second round hole 21 on the self-aligning block 2 is consistent with the center height of the fixed side, and tighten the hexagonal cylindrical screw 5 to adjust the center height of the support side of the lead screw, thereby ensuring the rigidity and stability of the lead screw system and extending the service life of the lead screw.

[0029] Example 2: Based on Example 1, such as Figure 3 and Figure 5 As shown, the fixing block 1 has longitudinal through holes 8 symmetrically opened on both sides of its first circular hole 11. A second adjusting screw is installed in the through hole 8. The second adjusting screw is also a hexagonal cylindrical screw 5. The through hole 8 is set as a countersunk hole 9, which facilitates the installation and adjustment of the second adjusting screw.

[0030] When the center height difference between the support side and the fixed side of the screw support is too large after installation, the height of the fixed block 1 and the self-aligning block 2 can be adjusted by adjusting the second adjusting screw in the through hole 8, thereby reducing the center height difference between the fixed side and the support side of the screw support, and facilitating the subsequent adjustment of the self-aligning block 2 to make the center height of the fixed side and the support side of the screw support consistent.

[0031] like Figure 3 As shown, a shaft retaining ring 6 is provided on the side of the bearing facing away from the fixing block 1 for locking onto the lead screw to fix the support side of the support. The shaft retaining ring 6 is made of elastic material, which can absorb impact and vibration, and extend the service life of the equipment, especially in high-speed machinery. Fixing holes 7 are provided at both ends of the opening of the shaft retaining ring 6.

[0032] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
