Description

Technical Field

[0001] This utility model relates to the field of optical instrument manufacturing technology, specifically a small optical alignment frame. Background Technology

[0002] Optical instruments are composed of multiple optical devices or a single optical device. They are mainly divided into two categories: optical instruments that form real images and optical instruments that form virtual images. Optical instruments are indispensable tools in all fields of society. However, during the production and manufacturing of optical instruments, a fixture is often required to fix the optical instruments to be produced.

[0003] In the prior art, there is a fixing frame for manufacturing optical instruments with the publication number CN219120111U. This utility model sets up a fixing device in which two stabilizing plates can cooperate with each other to fix the optical instruments to be produced placed in the frame in a stable and convenient manner, making the entire fixing frame more practical. Furthermore, with the action of the lifting device, the height of the entire fixing frame can be easily adjusted.

[0004] However, while this type of optical alignment frame can be used to fix the optical instrument to be processed by clamping blocks, the shape of the clamping blocks is relatively fixed. Alternating between clamping blocks of different shapes for optical instruments of different shapes is not very effective, which reduces the adaptability and stability of the clamping blocks for fixing different shaped instruments and affects the processing efficiency of optical instruments of different shapes on the alignment frame.

[0005] Therefore, in view of this, we studied and improved the existing structure to address its shortcomings and proposed a small optical alignment frame. Utility Model Content

[0006] The purpose of this invention is to provide a small optical alignment frame to solve the problem mentioned in the background art that the shape of the clamping block is relatively fixed and that the effect of alternating clamping blocks of different shapes with different optical instruments is not high.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a small optical alignment frame, comprising a manufacturing base, a manufacturing table slidably connected to the inner wall of the manufacturing base, an alignment slide plate slidably connected to the outer wall of the manufacturing table, a connecting frame fixedly connected to the outer wall of the alignment slide plate, a swing rod rotatably connected to the outer wall of the connecting frame, a first limiting rod slidably connected to the outer wall of the alignment slide plate, and a second limiting rod slidably connected to the outer wall of the alignment slide plate. A first alignment block is detachably connected to the end of the first limiting rod, and a second alignment block is detachably connected to the end of the second limiting rod.

[0008] Furthermore, a first limiting groove is provided at the connection between the outer wall of the swing rod and the first limiting rod, and a second limiting groove is provided at the connection between the outer wall of the swing rod and the second limiting rod. A connecting shaft is fixedly connected to the rotation center of the swing rod, and a connecting gear is fixedly connected to the outer wall of the connecting shaft. A telescopic rod is slidably connected to the outer wall of the connecting frame. A locking rod that engages with the outer wall of the connecting gear is fixedly connected to one end of the telescopic rod. A spring that is fixedly connected to the outer wall of the connecting frame is sleeved on the outer wall of the telescopic rod, and a connecting block that is fixedly connected to one end of the telescopic rod is fixedly connected to one end of the telescopic rod.

[0009] Furthermore, the centering slide plate is provided in two sets, and the two sets of centering slide plates are driven by a bidirectional lead screw.

[0010] Furthermore, the positions of the first limiting rod and the second limiting rod are equidistant from the rotation center of the swing rod.

[0011] Furthermore, the first alignment block and the first limiting rod are engaged by bolts, and the second alignment block and the second limiting rod are engaged by bolts.

[0012] Furthermore, the rotation centers of the connecting gear and the connecting shaft are on the same horizontal plane as the rotation center of the swing rod.

[0013] Furthermore, the outer wall contour of the pressing part between the clamping rod and the connecting gear is inclined, and the movement trajectory of the clamping rod is set in the middle part of the sawtooth on the surface of the connecting gear.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The swing rod provided in this utility model, when used in the manufacturing of optical instruments assisted by the alignment frame, improves the adaptability to the adjustment and positioning of different appearance instruments and enhances the stability of different instruments in the processing on the alignment frame. By rotating the swing rod, the first limiting groove and the second limiting groove limit the first limiting rod and the second limiting rod to slide alternately, so that the first alignment block and the second alignment block alternately clamp and fix the outer wall of the instrument, thereby improving the flexibility of the alignment frame in adjusting and fixing different optical instrument parts.

[0016] 2. This utility model, by setting a locking rod, improves the self-locking effect of the swing rod after rotation when adjusting alignment blocks of different appearances by rotating the swing rod. The rotating connecting shaft, connected by a connecting gear, drives the swing rod to rotate. At the same time, the connecting gear compresses the locking rod and synchronously lifts and compresses the telescopic rod and spring. When the connecting shaft stops rotating, the locking rod moves to the middle part of the serrations on the gear surface. At this time, under the reaction force of the spring being compressed, the telescopic rod and the locking rod move downward, so that the locking rod engages and fixes with the connecting gear, improving the convenience of self-locking after the swing rod rotates.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] like Figures 1-4As shown, a small optical alignment frame includes a manufacturing base 1, a manufacturing table 2 slidably connected to the inner wall of the manufacturing base 1, an alignment slide plate 3 slidably connected to the outer wall of the manufacturing table 2, a connecting frame 11 fixedly connected to the outer wall of the alignment slide plate 3, a swing rod 4 rotatably connected to the outer wall of the connecting frame 11, a first limiting rod 5 slidably connected to the outer wall of the alignment slide plate 3, a second limiting rod 6 slidably connected to the outer wall of the alignment slide plate 3, a first alignment block 7 detachably connected to the end of the first limiting rod 5, and a second alignment block 8 detachably connected to the end of the second limiting rod 6.

[0027] like Figure 2 As shown, there are two sets of centering slide plates 3. The two sets of centering slide plates 3 are driven by bidirectional lead screws, which facilitates the setting of the centering slide plates 3 by driving them with bidirectional lead screws, and plays a role in conveniently fixing and processing the outer wall of optical instruments.

[0028] like Figure 3 As shown, the positions of the first limiting rod 5 and the second limiting rod 6 are equidistant from the rotation center of the swing rod 4. This arrangement facilitates the alternating use of alignment blocks of different shapes.

[0029] like Figure 3 As shown, the first alignment block 7 and the first limiting rod 5 are engaged by bolts, and the second alignment block 8 and the second limiting rod 6 are engaged by bolts. This arrangement facilitates the easy disassembly and replacement of alignment blocks of different shapes.

[0030] Example 2:

[0031] like Figure 1 and Figure 5 As shown, a first limiting groove 9 is provided at the connection between the outer wall of the swing rod 4 and the first limiting rod 5, and a second limiting groove 10 is provided at the connection between the outer wall of the swing rod 4 and the second limiting rod 6. A connecting shaft 12 is fixedly connected to the rotation center of the swing rod 4, and a connecting gear 13 is fixedly connected to the outer wall of the connecting shaft 12. A telescopic rod 14 is slidably connected to the outer wall of the connecting frame 11. A locking rod 15 that engages with the outer wall of the connecting gear 13 is fixedly connected to one end of the telescopic rod 14. A spring 16 that is fixedly connected to the outer wall of the connecting frame 11 is sleeved on the outer wall of the telescopic rod 14. A connecting block 17 that is fixedly connected to one end of the telescopic rod 14 is fixedly connected to one end of the spring 16.

[0032] In the above technology, by setting the locking rod 15, it is beneficial to adjust the alignment blocks of different appearances by rotating the swing rod 4. In order to improve the self-locking effect of the swing rod 4 after rotation, the rotating connecting shaft 12 drives the swing rod 4 to rotate through the connection of the connecting gear 13. At the same time, the connecting gear 13 will squeeze the locking rod 15 and synchronously lift and squeeze the telescopic rod 14 and the spring 16. When the connecting shaft 12 stops rotating, the locking rod 15 will move to the middle part of the serrations on the gear surface. At this time, under the reaction force of the spring 16 being squeezed, the telescopic rod 14 and the locking rod 15 will move downward, so that the locking rod 15 will engage and fix the connecting gear 13, improving the convenience of self-locking after the swing rod 4 rotates.

[0033] like Figure 5 As shown, the rotation centers of the connecting gear 13 and the connecting shaft 12 are on the same horizontal plane as the rotation center of the swing rod 4. This arrangement facilitates the convenient rotation of the swing rod 4.

[0034] like Figure 5 As shown, the outer wall contour of the pressing part of the clamping rod 15 and the connecting gear 13 is inclined, and the movement trajectory of the clamping rod 15 is set in the middle part of the saw teeth on the surface of the connecting gear 13. This is beneficial to improve the convenience of self-locking after the swing rod 4 rotates by setting the outer wall contour of the pressing part of the clamping rod 15 and the connecting gear 13 to be inclined.

[0035] Working principle: When using this small optical alignment frame, firstly, in order to improve the adaptability of adjusting and positioning different appearance instruments and improve the stability of processing different instruments on the alignment frame, the swing rod 4 is rotated. Through the limiting action of the first limiting groove 9 and the second limiting groove 10, the first limiting rod 5 and the second limiting rod 6 slide alternately, so that the first alignment block 7 and the second alignment block 8 alternately clamp and fix the outer wall of the instrument, thereby improving the flexibility of the alignment frame in adjusting and fixing different optical instrument parts.

[0036] Finally, when adjusting the alignment blocks of different appearances by rotating the swing rod 4, in order to improve the self-locking effect of the swing rod 4 after rotation, the rotating connecting shaft 12 is connected by the connecting gear 13 to drive the swing rod 4 to rotate. At the same time, the connecting gear 13 will squeeze the locking rod 15 and synchronously lift and squeeze the telescopic rod 14 and the spring 16. When the connecting shaft 12 stops rotating, the locking rod 15 will move to the middle part of the serrations on the gear surface. At this time, under the reaction force of the spring 16 being squeezed, the telescopic rod 14 and the locking rod 15 will move downward, so that the locking rod 15 will engage and fix the connecting gear 13, improving the convenience of self-locking after the swing rod 4 rotates.

Many modifications and variations will be apparent to those skilled in the art.
