Technical Field

[0001] This utility model relates to the field of lifting component technology, and in particular to a lifting component. Background Technology

[0002] In the industrial manufacturing field, post-production quality inspection of workpieces (such as dimensional measurement and surface defect identification) is a key link in ensuring product quality. During inspection, the workpiece often needs to be stably supported to a specific height to meet the positioning requirements of sensors or vision inspection systems. However, the support mechanisms of existing inspection platforms are mostly fixed in height. When dealing with workpieces of different thicknesses and specifications, different support mechanisms need to be replaced, which increases the difficulty of operation. Therefore, this solution proposes a lifting component to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a lifting component to solve the problems mentioned in the background art.

[0023] 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.

[0024] This utility model provides, for example Figure 1 - Figure 4 A lifting assembly shown includes:

[0025] Workbench 1;

[0026] Support frame 2 is installed on top of workbench 1;

[0027] Base 3 is located at the bottom of support frame 2 and is fixedly connected to the top of workbench 1;

[0028] Limiting component 4 is provided at the connection between the support frame 2 and the base 3, and is used to limit the movement direction of the support frame 2;

[0029] Lifting component 5 is installed at the connection between support frame 2 and base 3, and is used to adjust the height of support frame 2.

[0030] It should be noted that the testing equipment consists of a tube-mounting fixture, a lifting component 5, a helium injection pipe, and a cover. In use, the workpiece is first placed on the lifting component 5, and the hollow tube at one end of the workpiece is inserted into the tube-mounting fixture. Then, the handle on the tube-mounting fixture is manually turned clockwise. The sealing ring inside deforms, sealing the workpiece. After the cover is closed, helium gas is injected through the helium injection pipe, completing the workpiece inspection. When testing products of different thicknesses, the movement direction of the support frame 2 is restricted by the limiting component 4, and the height of the support frame 2 is adjusted by the lifting component 5, thereby adjusting the height of the workpiece located at the top of the support frame 2. This adapts to the testing of workpieces of different heights, avoiding the need to change different support mechanisms for workpieces of different thicknesses.

[0031] Specifically, the limiting component 4 includes a second limiting groove 405 symmetrically opened on the front and back of the base 3, a first limiting groove 401 symmetrically opened on the front and back of the support frame 2, a limiting plate 403 interlocking between the first limiting groove 401 and the second limiting groove 405, a first bolt 402 provided at the connection between the first limiting groove 401 and the limiting plate 403, and a second bolt 404 provided at the connection between the limiting plate 403 and the second limiting groove 405.

[0032] It should be noted that the first limiting groove 401 and the second limiting groove 405 are adapted to the limiting plate 403. The limiting plate 403 is fixedly connected to the inside of the second limiting groove 405 by the second bolt 404. The moving direction of the support frame 2 is restricted by the multiple limiting plates 403. When the support frame 2 moves to the required height, the first bolt 402 is tightened to fix the support frame 2 and the limiting plate 403, thereby determining the height of the support frame 2.

[0033] Specifically, the lifting component 5 includes a push rod 501 located at the bottom of the support frame 2, a push block 503 located at the bottom of the push rod 501, the bottom of the push rod 501 being an arc-shaped surface, the horizontal longitudinal section of the push block 503 being an isosceles trapezoid, a sliding groove 502 being provided at the top of the base 3, the push rod 501 being inserted into the inner wall of the top of the sliding groove 502, the push block 503 being inserted into the interior of the sliding groove 502, a threaded cylinder 509 being fixedly connected to one side of the base 3, a threaded rod 506 being threadedly inserted into the middle of the threaded cylinder 509, a knob 507 being provided at one end of the threaded rod 506, a locking groove 504 and a through groove 508 being provided at the top of the push block 503, a convex block 505 being inserted into the interior of the locking groove 504 and the through groove 508, and the convex block 505 being fixedly connected to the other end of the threaded rod 506.

[0034] It should be noted that the locking groove 504 and the through groove 508 are adapted to the convex block 505. The convex block 505 is composed of two cylinders, which allows the convex block 505 to rotate inside the locking groove 504 and the through groove 508. Through the convex design, the convex block 505 cannot be moved out of the locking groove 504 through the through groove 508, thus connecting the convex block 505 and the push block 503. The threaded rod 506 and the push block 503 are connected through the convex block 505 and the push block 503, while the threaded rod 506 can rotate on one side of the push block 503. A through hole is opened on the inner wall of the top of the sliding groove 502. The outer wall of the push rod 501 fits against the inner wall of the through hole, and the movement direction of the push rod 501 is restricted by the through hole.

[0035] Furthermore, when it is necessary to adjust the height of the support frame 2, the threaded rod 506 is rotated. The rotating threaded rod 506 drives the threaded cylinder 509, which is threaded to it but cannot move, to move. The moving threaded rod 506 drives the push block 503 to move. When the inclined surface of the push block 503 contacts the arc-shaped surface of the push rod 501, the push block 503 drives the push rod 501 to move, thereby realizing the adjustment of the height of the support frame 2.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
