Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of axial gap adjustment, in particular to a magnetically controlled axial gap adjustment device. Background Art
[0002] During the assembly process of two or more assemblies, the bending deformation and cumulative tolerance of the assemblies may easily cause the assemblies to not be accurately matched. Therefore, an axial clearance adjustment device is usually required to control the axial position of its adjustment component to eliminate the above deviations so that the relative positions of the parts meet the design requirements.
[0003] However, there are some problems with the existing technology: most existing axial gap adjustment devices use metal parts or a combination of metal and plastic, and adjust the axial tolerance through the friction between the bolts and the friction unit. However, when making fine adjustments in a small space, it is difficult to add fasteners between the sheet metal parts for adjustment and locking, and traditional tightening tools and tolerance adjusters cannot be used. Therefore, we propose a magnetically controlled axial gap adjustment device. Utility Model Content

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] like Figures 1 to 7 As shown, the magnetically controlled axial gap adjustment device provided by the embodiment of the present invention includes a shell 1, hooks 2 are provided on both sides of the shell 1, a cover 3 is provided on the top of the inner cavity of the shell 1, a first flange 4 is provided on the top of the outer surface of the cover 3, a through hole 5 is provided between the cover 3 and the first flange 4, a steel nail 6 is movably inserted into the inside of the through hole 5, a second flange 7 is provided on the top of the outer surface of the steel nail 6, a bottom positioning groove 9 is provided in the middle of the bottom end of the inner wall of the shell 1, and wedge blocks 11 are movably installed on the bottom of the inner wall of the shell 1 on both sides of the bottom positioning groove 9, and the wedge blocks 11 are connected to the steel nail 6 through a snap-fit assembly.
[0025] Furthermore, the clamping assembly includes a side positioning block 10, and there are two side positioning blocks 10. The two side positioning blocks 10 are respectively fixedly installed on both sides of the inner wall of the shell 1. A side positioning groove 12 is provided on the side of the wedge block 11 close to the side positioning block 10. The inside of the side positioning groove 12 is fixedly connected to a first spring 13, and the other end of the first spring 13 is fixedly connected to the side positioning block 10. A sliding concave surface 14 is provided on the top of the wedge block 11, and a sliding convex surface 15 matching the sliding concave surface 14 is provided at the bottom of the cover 3. The outer surface of the steel nail 6 is provided with a first interlocking tooth 16, and the sliding concave surface 14 is provided with a second interlocking tooth 17 meshing with the first interlocking tooth 16.
[0026] The staff uses an external strong magnetic switch to attract the wedge block 11 and the steel nail 6 from above the steel nail 6, so that the wedge block 11 can be induced by magnetism to slide obliquely upward along the sliding convex surface 15 through the sliding concave surface 14, thereby disengaging the second interlocking tooth 17 from the first interlocking tooth 16. At the same time, since the movement of the wedge block 11 will compress the first springs 13 on both sides, the strong magnetic switch moves upward or downward to drive the steel nail 6 to be pulled out or pressed into the adjusting device. After the steel nail 6 is adjusted to the desired position, the external magnetic switch is turned off, and the elastic release of the first spring 13 pushes the two wedge blocks 11 to move toward the steel nail 6, and enables the second interlocking tooth 17 to be engaged and fixed with the first interlocking tooth 16, thereby achieving fine adjustment in a narrow space.
[0027] Furthermore, a second spring 18 is fixedly mounted on the bottom of the inner wall of the bottom positioning groove 9 , and the top of the second spring 18 abuts against the bottom of the steel nail 6 .
[0028] By designing the second spring 18 , the axial clearance caused by error or wear in the adjustment device can be compensated by elastic deformation thereof, thereby achieving fine control of the axial clearance.
[0029] Furthermore, a guide block 19 is provided at the bottom of the steel nail 6 , and the guide block 19 is inserted into the middle area of the second spring 18 .
[0030] The design of the guide block 19 can make the second spring 18 more stable when the steel nail 6 compresses the second spring 18 downward, ensuring that the top of the second spring 18 abuts against the bottom of the steel nail 6.
[0031] Furthermore, a thread groove 20 is provided on the top of the inner wall of the shell 1 , and a thread tooth 21 is provided on the outer surface of the cover 3 below the first flange 4 . The cover 3 and the shell 1 are locked by the thread groove 20 and the thread tooth 21 .
[0032] Furthermore, an upper hook 8 is fixedly installed on the top of the second flange 7. There are two upper hooks 8, and the two upper hooks 8 are symmetrically arranged.
[0033] By opening a hole on the upper sheet metal corresponding to the position of the upper hook 8 , the upper sheet metal can be clamped onto the second flange 7 through the upper hook 8 .
[0034] Furthermore, the height of the top of the hook 2 is smaller than the height of the top of the housing 1 , and the diameter of the first flange 4 is larger than the diameter of the housing 1 .
[0035] By sleeved the lower sheet metal on the outer surface of the shell 1, the hook 2 can support the lower sheet metal, and then the cover 3 is screwed into the inside of the shell 1 so that the edge of the bottom end of the first flange 4 fits on the lower sheet metal, thereby forming a limiting and fixing effect of the hook 2 and the first flange 4 on the lower sheet metal.
[0036] The working principle and use process of this utility model:
[0037] First, the staff puts the lower sheet metal on the outer surface of the shell 1 so that the hook 2 supports the lower sheet metal, and then screws the cover 3 into the inside of the shell 1 so that the hook 2 and the first flange 4 form a limiting and fixing effect on the lower sheet metal, and then limits the upper sheet metal to the top of the second flange 7 through the upper hook 8, inserts the steel nail 6 into the through hole 5, and when adjusting the gap between the two sheet metals, the staff attracts the wedge block 11 and the steel nail 6 from above the steel nail 6 through the external strong magnetic switch, so that the wedge block 11 can be magnetically induced to slide obliquely upward along the sliding convex surface 15 through the sliding concave surface 14, thereby enabling the second The second interlocking teeth 17 are disengaged from the first interlocking teeth 16. At the same time, the movement of the wedge block 11 will compress the first springs 13 on both sides. The strong magnetic switch moves upward or downward to drive the steel nail 6 to be pulled out or pressed into the adjustment device. After the steel nail 6 is adjusted to the desired position, the external magnetic switch is turned off. The elastic release of the first spring 13 pushes the two wedge blocks 11 to move toward the steel nail 6, and makes the second interlocking teeth 17 mesh and fix with the first interlocking teeth 16 again, thereby realizing fine adjustment in the narrow space between the two sheet metals on the housing 1 and the second flange 7. No additional fasteners are required for adjustment and locking, which is easy to use.
[0038] The above embodiments are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
