Description

Technical Field

[0001] This utility model relates to the field of gap adjustment technology, specifically a fine-tuning mechanism. Background Technology

[0002] In equipment, there are situations where moving parts need to be moved upwards. For upward movement, linear motors, cylinders, electric cylinders, etc. can be used. However, these driving methods are more suitable for situations where the upward movement distance is relatively large. When fine-tuning of the upward movement is required, these driving methods are obviously unsuitable. In this case, it is urgent to develop a fine-tuning mechanism to drive the moving parts to achieve upward fine-tuning. Utility Model Content

[0015] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Reference Figure 1-3 As shown, a fine-tuning mechanism in this embodiment includes a base 1, a cylinder 2, a bearing seat 3, and a rotating shaft 4; The base 1 body is provided with an upward-facing elongated groove 100, and the base 1 is mounted on the equipment; The cylinder 2 is located inside the long groove 100. The axial direction of the cylinder 2 is parallel to the length direction of the long groove 100. The diameter of the cylinder 2 is equal to the width of the long groove 100. Both ends of the cylinder 2 protrude from both ends of the long groove 100. Eccentric shafts 200 parallel to its axial direction are symmetrically provided on the end faces of both ends of the cylinder 2. The cylinder 2 abuts against the lower end of the moving part on the equipment that needs to be moved up for fine adjustment. There are two sets of bearing housings 3. The two sets of bearing housings 3 are integrated with the base 1 and are symmetrically arranged at both ends of the long groove 100 on the base 1. There are two sets of rotating shafts 4, which are respectively mounted on two sets of bearing seats 3. The end faces of adjacent long grooves 100 on the two sets of rotating shafts 4 are symmetrically provided with eccentric holes 400 that cooperate with eccentric shafts 200. The eccentric shafts 200 are inserted into the eccentric holes 400. The eccentric shafts 200 and the eccentric holes 400 are specifically fitted with clearance.

[0017] How this application works: like Figure 4As shown, by synchronously driving the two sets of rotating shafts 4 to rotate in the same direction or driving any one set of rotating shafts 4 to rotate, the eccentric hole 400 on the rotating shaft 4 will drive the eccentric shaft 200 to move in an arc. The eccentric shaft 200 will then drive the cylinder 2 to move linearly along the depth direction of the long groove 100 under the constraint of the long groove 100. When the cylinder 2 is moving linearly, the cylinder 2 will drive the moving part that abuts against it to move linearly, thereby achieving upward fine adjustment.

[0018] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
