[0001] The utility model relates to the technical field of optical instrument parts processing, in particular to a multi-faceted positioning tooling for an elbow of an optical instrument part. Background Technique

[0002] An optical instrument is composed of a single or multiple optical devices combined. Optical instruments are mainly divided into optical instruments that form real images and optical instruments that form virtual images. The types of components of optical instruments are diverse. However, due to the special structure of the elbow of the optical instrument, when processing the elbow, a multi-faceted positioning tooling is required to fix the elbow.

[0003] After retrieval, the patent with the publication number CN210210088U discloses a multi-faceted positioning tooling for an elbow of an optical instrument part, which positions the elbow by setting an arc surface processing component, an inclined surface processing component, and a flat surface processing component. However, when the device is actually applied, the three processing components can only fix different surfaces of elbows with the same size and cannot fix elbows with different sizes. Therefore, the versatility of the device is relatively poor. Secondly, after the elbow is fixed, the angle of the elbow cannot be adjusted, which has certain limitations during processing. Therefore, further improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and to propose a multi-faceted positioning tooling for an elbow of an optical instrument part.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] As Figures 1 - 4 shown, it relates to a multi-faceted positioning tool for elbows of optical instrument parts, including a base 1. A top seat 2 is provided on the upper surface of the base 1, and both the base 1 and the top seat 2 are hollow inside. The top wall of the base 1 penetrates and is rotatably connected to a vertical shaft 3 through a bearing. The top end of the vertical shaft 3 is fixedly connected to the lower surface of the top seat 2. A driving assembly 4 for driving the vertical shaft 3 to rotate is provided inside the base 1. Two rows of symmetrically arranged multiple chutes 5 are opened on both sides of the top seat 2. A slide block 6 is slidably connected inside each chute 5, and a strip-shaped opening 7 is opened at the top of each chute 5. A detachable positioning column 8 is fixed on the upper surface of the slide block 6. An adjusting assembly 9 for driving the slide block 6 to move is provided inside each chute 5.

[0023] Side plates 10 are fixed on both sides of the base 1, and multiple mounting holes 11 are opened on the side plates 10.

[0024] The side plate 10 can be fixed through the mounting hole 11, thereby fixing the base 1 at a specified position.

[0025] The driving assembly 4 includes a worm gear 41 fixed on the surface of the vertical shaft 3 and a horizontal shaft 42 horizontally arranged inside the base 1. The horizontal shaft 42 is rotatably connected to the side wall of the base 1 through a bearing. A worm 43 is fixed on the surface of the horizontal shaft 42. The worm 43 meshes with the worm gear 41. One end of the horizontal shaft 42 extends to the outside of the base 1 and is fixedly connected to a handwheel 44.

[0026] After the worm 43 is rotated by the handwheel 44, the worm 43 can drive the worm gear 41 and the vertical shaft 3 to rotate, thereby driving the top seat 2 to rotate by using the vertical shaft 3. When an elbow is fixed on the surface of the top seat 2, the angle of the elbow can be adjusted without disassembling the elbow, and the worm 43 and the worm gear 41 have a self-locking effect, which can ensure the stability after adjustment.

[0027] The adjusting assembly 9 includes a lead screw 91 horizontally arranged inside the chute 5. Both ends of the lead screw 91 are rotatably connected to the side walls of the chute 5 through bearings. One end of the lead screw 91 extends outside the top seat 2 and is fixedly connected with a knob 92.

[0028] By rotating the lead screw 91 through the knob 92, the lead screw 91 can drive the slider 6 to move along the chute 5, thereby driving the positioning column 8 to move.

[0029] A screw rod 81 is fixedly installed at the bottom end of the positioning column 8. A threaded groove 61 for screwing the screw rod 81 is formed on the upper surface of the slider 6. The screw rod 81 is slidably connected with the strip-shaped opening 7.

[0030] In this embodiment, the positioning column 8 can be designed into different shapes. When fixing elbows of different types, the positioning column 8 can be disassembled from the surface of the slider 6 and replaced. The disassembly and assembly method is to screw the screw rod 81 into or out of the threaded groove 61.

[0031] A rubber sleeve is fixedly sleeved on the outer side wall of the positioning column 8. When the positioning column 8 presses the elbow, the rubber sleeve can increase the friction force and protect the surface of the elbow.

[0032] Working principle: Place the elbow between two rows of positioning columns 8 on the surface of the top seat 2. First, drive multiple positioning columns 8 on the same side to move through the adjusting assembly 9, so that the positioning columns 8 are attached to the surface of the elbow. Then, use the adjusting assembly 9 on the other side to drive the positioning columns 8 on the other side to press the other side of the elbow, thereby realizing the quick fixation of the elbow. This fixation method can fix elbows of different sizes. During the processing, the angle between the top seat 2 and the elbow can be adjusted by rotating the handwheel 44.

The preferred embodiments do not describe all the details in detail, nor do they limit the present invention to only the specific implementation manners. Obviously, according to the content of this specification, many modifications and changes can be made. This specification selects and specifically describes these embodiments to better explain the principle and practical application of the present invention, so that those skilled in the art in the relevant technical field can well understand and utilize the present invention. The present invention is only limited by the claims and their full scope and equivalents.
