Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary fixture for assembling guide posts, belonging to the technical field of optical lenses. Background Art
[0002] With the development of video, all-in-one machines are more and more widely used. One of the core components of its lens is a zoom lens. Through the optical zoom of the zoom lens, far and near images can be clearly imaged. Therefore, the optical quality of the zoom lens is closely related to the quality of image imaging. The all-in-one machine lens generally uses a guide post structure to guide the moving lens assembly. The quality of the guide post assembly has a direct impact on the lens imaging. Usually, the installation of the guide post is manually assembled into the lens body using tweezers and a syringe. During the manual assembly process, it is difficult to align the guide post with the guide post positioning hole in the body, resulting in very low manual efficiency, easy damage to other components, assembly skew, and difficult quality control. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides an auxiliary fixture for assembling guide posts to solve the technical problems of low assembly efficiency and difficult quality guarantee in the installation of guide posts of existing all-in-one machine lenses.
[0004] An auxiliary fixture for assembling guide posts, one end of the sleeve has a tapered end, the other end of the sleeve has a port, the diameter of the port is greater than the circumferential diameter of the sleeve, one end of the ejector pin has a port, the diameter of the port is greater than the circumferential diameter of the ejector pin, the return spring is sleeved outside the circumference of the ejector pin, and after the ejector pin is connected to the return spring, it is inserted into the through hole of the sleeve, and one end of the return spring is connected to the port at the other end of the sleeve. The ejector pin can reciprocate in the through hole of the sleeve.
[0005] The advantages of the utility model are: the production quantity of special fixtures can be effectively reduced, saving the design and production costs and the time costs generated by making the fixtures. It has strong continuous operability, can effectively improve the efficiency of on-site operators, and reduce the personnel costs generated by managing the fixtures. At the same time, it reduces the operation burden of operators.
[0006] The beneficial effect of the utility model is: the guide post can be quickly and conveniently clamped through the clamping device, and the aperture is roughly the same as the diameter of the guide post, which not only ensures that the guide post will not fall off during the processing, but also greatly improves the guide post assembly speed and increases the production capacity.

[0013] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description, the meaning of "a plurality" is two or more, unless otherwise specifically defined, and the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0014] Those skilled in the art of this technology can understand that, unless otherwise defined, all terms used herein, including technical terms and scientific terms, have the same meaning as the general understanding of those of ordinary skill in the art in the relevant field.
[0015] For the convenience of understanding the embodiments, further explanations will be given below in conjunction with [specific content not provided], and each embodiment does not constitute a limitation to the embodiments of the utility model.
[0016] Embodiment 1: As shown in Figure 1 , Figure 2 and Figure 3 , a guide post assembly auxiliary jig, the sleeve 1 has a through hole, one end of the sleeve 1 has a tapered end, the other end of the sleeve 1 has a port, the diameter of the port is greater than the circumferential diameter of the sleeve 1, one end of the ejector pin 2 has a port, the diameter of the port is greater than the circumferential diameter of the ejector pin 2, the return spring 3 is sleeved outside the circumference of the ejector pin 2, after the ejector pin 2 is connected to the return spring 3, it is inserted into the through hole of the sleeve 1, and one end of the return spring 3 is connected to the port at the other end of the sleeve 1, and the return spring 3 plays a role in fixing and resetting.
[0017] The ejector pin 2 of the second component is inserted into the through-hole of the sleeve 1 of the first component. The reset spring 3 is assembled onto the ejector pin 2. The ejector pin 2 is connected to the through-hole of the sleeve 1 and can reciprocate within the through-hole. The outer diameter of the ejector pin 2 matches the inner diameter of the through-hole of the sleeve 1. One end of the ejector pin 2 is equipped with a reset spring 3, which can achieve free sliding during reset and prevent the ejector pin 2 from ejecting out of the sleeve 1.
[0018] Select the corresponding guide post assembly auxiliary fixture according to the outer diameter of different models of guide posts. First, insert the guide post to be assembled into the Figure 3 through-hole at the conical head end of the sleeve 1. Hold the sleeve 1 of the assembly auxiliary fixture by hand, align one end of the guide post assembled to the auxiliary fixture with the corresponding guide post positioning hole of the part, and manually press the ejector pin 2 vertically with the thumb to assemble the guide post into the guide post positioning hole. Release the thumb, and the reset spring resets the ejector pin 2 to achieve the purpose of assembling the guide post.
[0019] A guide post assembly auxiliary fixture, where the inner diameter of the through-hole of the sleeve 1 corresponds and cooperates with the guide post positioning hole of the body of the integrated machine lens. The position of the guide post cooperates with the acupoint of the guide post positioning hole inside the body. By pressing the ejector pin, the guide post is assembled into the corresponding guide post positioning hole of the body, which improves the efficiency and quality of assembling the guide post into the integrated machine lens, and can determine whether the guide rod is assembled in place, ensuring the quality.
