Description

Technical Field

[0001] The utility model relates to the technical field of sleeves, in particular to a sleeve positioning mechanism. Background Art

[0002] The subframe assembly needs to weld the bushing tube to the main body before the bushing pressing process. Since the subframe assembly weld is relatively long, thermal deformation is easily generated during the welding process, causing the bushing tube to shift. Ordinary locating pins can effectively prevent deformation, but too many locating pins will cause over-positioning, making it difficult to remove and install parts.

[0003] To this end, we propose a casing positioning mechanism. Utility Model Content

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 , Figure 2 , Figure 3 As shown, a sleeve positioning mechanism comprises a support plate 1, a fixed plate 2 is welded at the center of the upper end surface of the support plate 1, a threaded rod 3 is arranged on the inner side of the fixed plate 2, and a moving block 4 is threadedly connected to the upper outer side of the threaded rod 3; the fixed plate 2 is a horizontally arranged circular plate structure, a first support rod 5 is welded on the top of the fixed plate 2, the first support rod 5 is arranged in four groups in a circular array with the center of the fixed plate 2 as the center, a positioning assembly 6 is arranged on the top of the first support rod 5, and the positioning assembly 6 comprises a positioning plate 7, a telescopic device 9, an extrusion plate 10, a slider 11, a second support rod 13 and a spring device 15.

[0020] The top end of the first support rod 5 is fixedly connected to the bottom end of the positioning plate 7. The positioning plate 7 is a horizontally arranged arc-shaped columnar structure. The positioning plates 7 are arranged in four groups in a ring array with the fixed plate 2 as the center. A rack plate 16 is installed on the outer side of the positioning plate 7, and a sleeve 17 is provided on the outer side of the rack plate 16; a slide groove 8 is provided on the inner side of the positioning plate 7, and a telescopic device 9 for connecting with the extrusion plate 10 is fixedly installed in the center of the slide groove 8, and the extrusion plate 10 is sleeved on the outer side of the moving block 4; two groups of relatively arranged sliders 11 are provided inside the slide groove 8, and the sliders 11 are located on both sides of the telescopic device 9, and one end of the slider 11 is installed with a first connecting shaft 12 connected to the second support rod 13, and the second support rod 13 is connected to the second support rod 13 through a second connecting shaft 14. The spring device 15 is connected to the extrusion plate 10; a spring device 15 is installed on the inner side of the positioning plate 7, and the other end of the spring device 15 is connected to the outer side of the extrusion plate 10. The spring device 15 is arranged in a circular array with the center of the extrusion plate 10 as the center, and the spring device 15 is located between two groups of adjacently arranged slide grooves 8; a third support rod 18 is fixedly installed at the four corners of the lower end surface of the support plate 1, a partition 19 and a base 20 are provided below the support plate 1, and the partition 19 is located between the support plate 1 and the base 20, the third support rod 18 passes through the partition 19 and is fixedly connected to the base 20, and a motor 21 is fixedly installed at the center of the upper end surface of the base 20, and the bottom end of the threaded rod 3 passes through the support plate 1 and the partition 19 and is connected to the output shaft at the top of the motor 21.

[0021] It should be noted that the utility model is a sleeve positioning mechanism. When in use, the sleeve 17 is first placed on the outside of the positioning plate 7, and then the output shaft at the top of the motor 21 is rotated, thereby driving the threaded rod 3 to rotate. Since the moving block 4 is threadedly connected to the threaded rod 3, the moving block 4 moves upward. Since the moving block 4 is a cylindrical structure with a small top and a large bottom, the moving block 4 squeezes the extrusion plate 10 outward while moving, so that the second support rod 13 drives the slider 11 to slide to both sides of the slide groove 8, and at the same time, the telescopic device 9 retracts inward to resist the positioning plate 7, and the spring device 15 applies elastic force to the positioning plate 7, so that the positioning plate 7 is firmly clamped on the inner side of the sleeve 17, and the rack plate 16 increases the friction force of the sleeve 17; when welding is completed, the output shaft at the top of the motor 21 rotates in the opposite direction and drives the threaded rod 3 to rotate together, so that the moving block 4 moves downward, and the positioning plate 7 retracts inward, thereby facilitating the removal of the sleeve 17.
