Description

Technical Field

[0001] This utility model relates to the field of optomechanical assembly technology, specifically a disassembly fixture for optomechanical assembly. Background Technology

[0002] Optomechanical assembly is a combination of optoelectronic instruments and mechanical structures to form precision assembly equipment. Fixtures are indispensable in the fabrication of optomechanical assembly. Different components may require different types of fixtures. Fixtures are structural components that can hold components.

[0003] The fixture still has some shortcomings, such as the inconvenience of disassembling the clamping plate when assembling the fixture.

[0004] To overcome the problem of inconvenient disassembly of clamping plates in assembly fixtures, a prior art Chinese patent (publication number: CN221818497U) discloses an assembly fixture that is easy to disassemble. It includes a base plate and side plates symmetrically arranged on the top of the base plate. A mounting plate capable of lateral movement is provided on the side of the side plate. A connecting block is movably inserted into the mounting plate. A clamping plate is fixedly connected to the side of the connecting block away from the mounting plate. Through the mutual cooperation of the base plate, side plates, mounting plate, connecting block, clamping plate, hydraulic cylinder, telescopic rod, fixed frame, rotating shaft, limit rod, limit block, stabilizing block, stabilizing rod, fixed plate, pull plate, and spring, the clamping plate can be easily disassembled and separated from the side plates. Workers can easily and quickly replace the clamping plate, reducing their workload, increasing work efficiency, and making it convenient to use.

[0005] However, the fixtures currently in use still have some shortcomings. The fixtures in the above document achieve the disassembly and separation of the clamping plate and the side plate through the cooperation of multiple components, which improves the efficiency of component replacement. However, the fixtures themselves use different models when clamping different components, and the replacement of fixture models is mostly inefficient. Therefore, it is necessary to improve the existing structure. Utility Model Content

[0006] The purpose of this utility model is to provide a disassembly fixture for optical-mechanical assembly, so as to solve the problem mentioned in the background art that the fixtures for optical-mechanical assembly are inconvenient to disassemble, which affects the efficiency of fixture model replacement.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disassembly fixture for optical-mechanical assembly, including a connecting seat, an external block connected to the side of the connecting seat, and a clamping block rotatably connected to the side of the external block.

[0008] An insert block is fixed to the center of the side of the external block away from the clamping block. The insert block and the slot are slidably connected. The slot is opened on the side of the connecting seat. The side of the external block is also provided with a torsion mechanism for disassembling the clamping block.

[0009] Furthermore, the torsion mechanism includes four fixed blocks fixed to the side of the outer block, and the fixed blocks are distributed around the center of the insertion block on the side of the outer block, and a rotating block is rotatably connected through the interior of the fixed blocks.

[0010] Furthermore, a spring sheet is fixed to the inner side of the rotating block, and an anti-slip texture is connected to the outer side of the rotating block. The rotating block, the fixed block, and the sliding groove form a sliding connection.

[0011] Furthermore, the slide groove is formed through the side of the connecting seat, and the spring piece and the positioning groove form a positioning connection, with the positioning groove being formed on the side of the slide groove.

[0012] Furthermore, the outer block is symmetrically fixed with connecting blocks on the side near the clamping block, and the two connecting blocks are rotatably connected with a clamping block. A motor is also installed inside the outer block, and a threaded rod is rotatably connected to the output end of the motor. A rotating mechanism is provided on the side of the outer block to improve the clamping stability of the clamping block.

[0013] Furthermore, the rotating mechanism includes a movable block threadedly connected to the surface of the threaded rod, and sliding rods are fixed on both the upper and lower sides of the movable block.

[0014] Furthermore, a rotating block is slidably connected to the surface of the sliding rod, and the sliding rod is inclined, with the side of the rotating block rotatably connected to the end of the clamping block.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This detachable fixture for optical engine assembly: When the model of the optical engine assembly fixture needs to be changed, first rotate the rotating block, which drives the spring to rotate and press the inner wall of the positioning groove. The spring deforms by its own material, causing the rotating block to rotate in the fixed block and the slide. After the four rotating blocks are rotated to the specified angle, the outer connecting block is pulled outward, and the fixed block can slide out of the slide, thereby separating the outer connecting block from the connecting seat and improving the fixture replacement efficiency.

[0017] 2. It is equipped with a spring clip that can engage with the positioning slot to position the rotating block. When the rotating block is positioned, the external block can also be positioned, which improves the efficiency of disassembling and assembling the external block and the connecting seat.

[0018] 3. It is equipped with a threaded rod. The threaded sliding between the threaded rod and the movable block can clamp the part with the clamping block. The threaded method of the threaded rod can prevent the part from loosening when it is clamped, thus improving the stability of the clamping fixture.

[0019] 4. A sliding rod is provided, which is inclined, so that the rotating block can slide more easily on the surface of the sliding rod when the clamping block rotates, reducing the jerking sensation when the rotating block slides. Attached Figure Description

[0027] 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.

[0028] Example 1, such as Figures 1-5The present invention provides the following technical solution to address the problem that the fixtures used in optical engine assembly are inconvenient to disassemble, affecting the efficiency of fixture model replacement. A torsion mechanism is disclosed: it includes a connecting seat 1, an external block 2 connected to the side of the connecting seat 1, a clamping block 3 rotatably connected to the side of the external block 2, and an insert block 101 fixed at the center of the side of the external block 2 away from the clamping block 3. The insert block 101 is slidably connected to a slot 102, which is located on the side of the connecting seat 1. A torsion mechanism for disassembling the clamping block 3 is also provided on the side of the external block 2. The torsion mechanism includes a fixed... Four fixing blocks 103 are fixed on the side of the outer block 2, and the fixing blocks 103 are distributed around the center of the insert block 101 on the side of the outer block 2. A rotating block 104 is rotatably connected through the inside of the fixing block 103. A spring piece 105 is fixed on the inner side of the rotating block 104, and anti-slip texture is connected on the outer side of the rotating block 104. The rotating block 104, the fixing block 103 and the slide groove 106 form a sliding connection. The slide groove 106 is opened through the side of the connecting seat 1. The spring piece 105 and the positioning groove 107 form a positioning connection. The positioning groove 107 is opened on the side of the slide groove 106.

[0029] When the fixture used for optical assembly needs to be changed, the rotating block 104 can be rotated first. When the rotating block 104 rotates, it can rotate the spring 105. When the spring 105 rotates, it can squeeze the inner wall of the positioning groove 107. When the spring 105 is squeezed, it can deform through its own material. When the spring 105 deforms, the rotating block 104 can rotate inside the fixed block 103. At the same time, the rotating block 104 can also rotate inside the slide groove 106. Rotate all four rotating blocks 104 to the specified angle and then pull the outer block 2 to the side. When the outer block 2 is pulled, it can move the fixed block 103 and the insertion block 101. When the fixed block 103 and the insertion block 101 move, they can slide through the slide groove 106 and the slot 102. When the fixed block 103 slides out of the slide groove 106, the outer block 2 and the connecting seat 1 can be separated. After the outer block 2 is separated, it can be disassembled and replaced, which improves the efficiency of fixture replacement and disassembly.

[0030] Example 2, as follows Figure 1 , Figure 2 , Figure 5 and Figure 6The present invention provides the following technical solution to address the problem of insufficient clamping stability in the fixtures used for optomechanical assembly: a rotating mechanism is disclosed. Connecting blocks 201 are symmetrically fixed to the side of the outer block 2 near the clamping block 3, and the clamping block 3 is rotatably connected between the two connecting blocks 201. A motor is also installed inside the outer block 2, and a threaded rod 202 is rotatably connected to the output end of the motor. A rotating mechanism is provided on the side of the outer block 2 to improve the clamping stability of the clamping block 3. The rotating mechanism includes a movable block 203 threadedly connected to the surface of the threaded rod 202. Sliding rods 204 are fixed to both the upper and lower sides of the movable block 203. A rotating block 205 is slidably connected to the surface of the sliding rod 204, and the sliding rod 204 is inclined. The side of the rotating block 205 is rotatably connected to the end of the clamping block 3.

[0031] When assembling the optomechanical device, the fixture needs to clamp the component. The motor needs to be started by the device's controller. The motor output end can then rotate the threaded rod 202. When the threaded rod 202 rotates, it can cause the movable block 203 to slide threadedly. When the movable block 203 slides threadedly, it can drive the sliding rod 204 to rotate and move. When the sliding rod 204 rotates and moves, it can squeeze the inner wall of the rotating block 205. When the inner wall of the rotating block 205 is squeezed, it can drive the clamping block 3 to rotate. When the clamping block 3 rotates, it can rotate on the side of the connecting block 201, and the clamping block 3 will also rotate on the side of the rotating block 205 at the same time. At this time, the rotating block 205 will slide on the surface of the sliding rod 204. When the clamping block 3 rotates to the side of the component, it can squeeze and clamp it. The threaded rod 202 drives the movable block 203 to move stably through the thread, and the self-locking effect of the threaded rod 202 can prevent the clamping block 3 from loosening. Thus, the clamping block 3 can stably clamp the component, which indirectly enhances the assembly effect.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
