Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. Rather, the invention can be practiced without these specific details, i.e., those skilled in the art can more effectively describe the nature of their work to others skilled in the art using the description and illustrations herein. Furthermore, it should be noted that the terms "front side", "rear side", "left side", "right side", "upper side", "lower side", and the like used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from the geometric center of a specific part, respectively, and those skilled in the art should not understand that the technology beyond the scope of the present application is simply and innovatively adjustable in the directions. It should be understood that the specific embodiments described herein are merely illustrative of the present application and do not limit the scope of the actual protection. Well-known manufacturing methods, control procedures, component dimensions, material compositions, pipe arrangements, etc., have not been described in detail since they are readily understood by those of ordinary skill in the art, in order to avoid obscuring the present invention.

Fig. 1 is a front view of an embodiment of the present invention, referring to fig. 1, an embodiment of the present invention provides a gear rack position gap fine adjustment structure, including a control main shaft 100 and a stroke moving member 200, a control gear 110 is provided on the control main shaft 100, and a stroke rack 210 is provided on the stroke moving member 200. The control gear 110 is engaged with the travel rack 210, so that the travel moving member 200 is moved in a translational manner when the control main shaft 100 rotates. The accuracy of the engagement of the control gear 110 with the travel rack 210 is critical.

Referring to fig. 2, 4, the stroke moving member 200 is provided with an adjusting member 300, and an inclined position 310 is provided between the stroke rack 210 and the adjusting member 300. That is, when the adjusting member 300 moves laterally, the adjusting member 300 drives the stroke rack 210 to move longitudinally through the inclined position 310. Therefore, by controlling the movement of the adjusting member 300, the stroke rack 210 can generate distance displacement with the gear, and fine adjustment of matching precision is realized.

Reference will now be made in detail to some embodiments, wherein "an embodiment" is referred to herein as a particular feature, structure, or characteristic that may be included in at least one implementation of the present application. The appearances of the phrase "in an embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Furthermore, the details representative of one or more embodiments are not necessarily indicative of any particular order, nor are they intended to be limiting.
