Description

Technical Field

[0001] This utility model relates to the field of optomechanical assembly technology, specifically to a high-efficiency positioning tooling for optomechanical assembly. Background Technology

[0002] Optomechanical assembly is a type of precision component assembly. During assembly, positioning fixtures are required to accurately fix and constrain the position and orientation of the workpiece, thereby ensuring the quality of the workpiece during processing.

[0003] Currently, positioning fixtures still have some shortcomings, such as the inconvenience of adjusting the workpiece angle.

[0004] To overcome the problem of inconvenient workpiece angle adjustment, a prior art Chinese patent (publication number: CN222711933U) discloses an assembly positioning fixture, which includes an assembly positioning fixture body. The upper surface of the assembly positioning fixture body has a receiving groove, and the front of the assembly positioning fixture body has a rectangular groove connected to the receiving groove. A first sliding groove is formed inside the rectangular groove. A bearing is provided at the bottom of the receiving groove, and a connecting rod is fixedly installed on the inner wall of the bearing. A rotating component is provided on the upper surface of the connecting rod. By pulling the handle, the extension rod pulls the auxiliary straight teeth. The movement of the auxiliary straight teeth causes the slider to slide inside the first sliding groove. The meshing connection between the auxiliary straight teeth and the auxiliary sleeve teeth causes the mounting block and the connecting rod to rotate through the bearing. The rotation of the mounting block achieves workpiece angle adjustment, avoiding the need to rotate the workpiece body, which would cause the workpiece position to shift, requiring readjustment to the center position for clamping, thus reducing work efficiency.

[0005] However, the positioning fixture currently in use still has some shortcomings. The positioning fixture in the above document achieves the angle adjustment of the workpiece by rotating the mounting block, but the positioning of the workpiece by this fixture uses two drive devices, which is relatively expensive and inconvenient for later maintenance. Therefore, it is necessary to improve the existing structure. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency positioning fixture for optomechanical assembly, so as to solve the problem of low fixing efficiency of the positioning fixture for the workpiece mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency positioning fixture for optomechanical assembly, comprising a base, wherein a fixture table is connected to the top of the base.

[0008] The tooling table has a through-hole rotating groove, and a bevel gear ring is rotatably connected to the rotating groove through a bearing. The inner side of the bevel gear ring has a tooth groove. A sliding block is also slidably connected through the rotating groove, and three sets of sliding blocks are distributed around the center of the rotating groove. The rotating groove is equipped with a rotating mechanism to improve the positioning efficiency of the workpiece.

[0009] Furthermore, the rotating mechanism includes a threaded rod that is threaded through the inside of the sliding block, and the threaded rod rotates inside the rotating groove via a bearing. A bevel gear is fixed to the end of the threaded rod, and the bevel gear is meshed with the side of the bevel gear ring.

[0010] Furthermore, a motor is installed inside the rotating groove, and a spur gear is connected to the output end of the motor. The spur gear is meshed with the tooth groove side of the inner side of the bevel gear ring, and a pressing block is connected to the top of the sliding block.

[0026] 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.

[0027] Example 1, such as Figures 1-3 The present invention provides the following technical solution to address the problem of low efficiency in fixing workpieces by positioning fixtures: a rotating mechanism is disclosed.

[0028] The device includes a base 1, with a tooling table 2 connected to the top of the base 1. A rotating groove 101 is formed inside the tooling table 2. A bevel gear ring 102 is rotatably connected inside the rotating groove 101 via a bearing. The inner side of the bevel gear ring 102 has a tooth groove. A sliding block 103 is also slidably connected inside the rotating groove 101, and three sets of sliding blocks 103 are distributed around the center of the rotating groove 101. A rotating mechanism for improving workpiece positioning efficiency is provided inside the rotating groove 101. The rotating mechanism includes a threaded rod 104 that is threaded through and connected inside the sliding block 103. The threaded rod 104 rotates inside the rotating groove 101 via a bearing. A bevel gear 105 is fixed to the end of the threaded rod 104. The bevel gear 105 is meshed with the side of the bevel gear ring 102. A motor is also installed inside the rotating groove 101. A spur gear 106 is connected to the output end of the motor. The spur gear 106 is meshed with the side of the tooth groove inside the bevel gear ring 102. A pressing block 107 is connected to the top of the sliding block 103.

[0029] When using the positioning fixture, the motor can be started first. The motor output can drive the spur gear 106 to rotate. When the spur gear 106 rotates, it can drive the inner tooth groove of the bevel gear ring 102 to mesh and rotate. When the bevel gear ring 102 meshes and rotates, it can rotate inside the rotating groove 101 through the bearing. When the bevel gear ring 102 rotates, it can drive the three sets of bevel gears 105 to mesh and rotate. When the bevel gears 105 mesh and rotate, they can drive the threaded rod 104 to rotate. When the threaded rod 104 rotates, it can rotate inside the rotating groove 101 through the bearing. When the threaded rod 104 rotates, it can drive the sliding block 103 to slide threadedly. When the sliding block 103 slides threadedly, it can slide inside the rotating groove 101. When the sliding block 103 slides, it can drive the pressing block 107 to press the outer and inner sides of the workpiece, which improves the efficiency and stability of the positioning fixture in positioning the workpiece.

[0030] Example 2, as follows Figures 3-6 The present invention provides the following technical solution: In order to solve the problem that the extrusion block 107 of the positioning fixture is inconvenient for quick replacement of the model of the processed part, a telescopic mechanism is disclosed based on the first embodiment: a sliding groove 201 is provided on the side of the extrusion block 107, and a telescopic mechanism for easy replacement of the extrusion block 107 is provided on the side of the extrusion block 107. The telescopic mechanism includes a sliding ring 202 that slides inside the sliding groove 201. A fixing block 203 is symmetrically fixed inside the sliding ring 202. A spring is connected between the fixing block 203 and the sliding groove 201. A slot 204 is symmetrically provided inside the extrusion block 107. A rotating groove 205 is provided on the side of the slot 204. An insert block 206 is slidably connected inside the rotating groove 205 and the slot 204. The insert block 206 is fixed on the side of the sliding block 103, and the insert block 206 and the fixing block 203 form a snap-fit ​​connection.

[0031] When the extrusion block 107 of the positioning fixture needs to be changed in style or model, the sliding ring 202 can be pressed down to drive the fixed block 203 to move. When the fixed block 203 moves, the sliding ring 202 can slide inside the sliding groove 201, and the fixed block 203 can slide inside the insert block 206 simultaneously. When the fixed block 203 slides, it can compress the spring. After the fixed block 203 is extruded from the insert block 206, the extrusion block 107 needs to be rotated. When the extrusion block 107 rotates, it can drive the rotating groove 205 to rotate. When the rotating slot 205 rotates, it can rotate the slot 204 to be directly below the insert block 206. At this time, the upward pressing block 107 can drive the slot 204 to move. When the slot 204 moves, it can slide on the side of the insert block 206. At the same time, the pressing block 107 can also slide on the side of the sliding block 103. When the slot 204 slides out of the side of the insert block 206, the pressing block 107 and the sliding block 103 can be separated. After separation, different pressing blocks 107 can be replaced, which improves the efficiency of pressing block 107 replacement.

[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.
