Auxiliary support for galvanometer performance detection

Abstract

This utility model discloses an auxiliary support for galvanometer performance testing, including a lifting mechanism, a lateral movement mechanism, and a main body. The lifting mechanism is equipped with a lateral movement mechanism. This auxiliary support for galvanometer performance testing achieves precise positioning of the galvanometer in three-dimensional space through a combination of a gear-rack lifting mechanism and a worm gear-worm lateral movement mechanism. The worm gear transmission has a self-locking function to prevent position drift. The connection between the rhomboid groove and the rhomboid rod ensures the reliability and centering of the transmission. When the connecting rod is pulled, the cooperation between the rhomboid groove and the rhomboid rod allows the main body to move vertically up and down or horizontally by rotating the turntable, either individually or simultaneously. This allows the main body to move up, down, left, and right with a single power source. The operation is simple and convenient for daily use. It can be used for performance testing of various types of galvanometers, has strong versatility, and is suitable for various scenarios such as laboratories and production lines.

It provides a stable, accurate, and repeatable mounting reference for core testing equipment, such as laser interferometers, position detectors (PSDs), and corner mirrors. It is a key auxiliary tool ensuring the accuracy and reliability of galvanometer measurement data. Although an auxiliary tool, this support is the cornerstone of building a highly reliable galvanometer testing system. By providing impeccable reference stability and ease of operation, it greatly improves the confidence of test results and work efficiency. It is crucial for ensuring the final performance of high-end laser processing equipment and precision optical measurement systems, and is an indispensable professional tool in the galvanometer application industry chain. However, existing auxiliary supports for galvanometer performance testing still have certain shortcomings. While traditional auxiliary supports for galvanometer performance testing can be used effectively, they may only offer height or horizontal adjustment and are typically fixed using simple sliding grooves and locking screws. This results in low adjustment precision, easy loosening, and an inability to meet the high precision and fine-tuning requirements of galvanometer performance testing. Furthermore, they require multiple power sources to drive both horizontally and vertically, making operation cumbersome and inconvenient for daily use, often causing inconvenience to users.

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.

[0014] Please see Figures 1-4 This utility model provides a technical solution: an auxiliary support for galvanometer performance testing, including a lifting mechanism 1, a lateral moving mechanism 2, and a body 3. The lifting mechanism 1 is provided with the lateral moving mechanism 2, and the lateral moving mechanism 2 is provided with the body 3. The lifting mechanism 1 includes a base 101, a support column 102, a rack 103, a gear 104, a rotating shaft 105, and a housing 106. The support column 102 is fixedly installed on the upper top surface of the base 101. The rack 103 is fixedly installed on the support column 102. The gear 104 meshes with the rack 103. The rotating shaft 105 is fixedly installed on the gear 104. The housing 106 is slidably connected through the support column 102, and the rotating shaft 105 and the housing 106 are connected by a bearing. A turntable is fixedly installed at the other end of the rotating shaft 105.

[0015] The transverse moving mechanism 2 includes a worm 201, a worm wheel 202, a lead screw 203, a slide bar 204, a diamond groove 205, a diamond rod 206, a connecting seat 207, and a connecting rod 208. The rotating shaft 105 has a diamond groove 205, and the diamond rod 206 is fixedly installed on the worm 201.

[0016] The rhomboid rod 206 is used in conjunction with the rhomboid groove 205, and the rhomboid rod 206 and the rhomboid groove 205 are slidably connected. The worm gear 201 is meshed with a worm wheel 202 below, and the lead screw 203 is slidably connected to the worm wheel 202 by a key.

[0017] The left side of the lead screw 203 is slidably connected to the housing 106, and the right end of the lead screw 203 is threadedly connected to the housing 106. The lead screw 203 is symmetrically provided with a slide rod 204 about the center of the housing 106.

[0018] The worm gear 201 is connected to a bearing seat 207, and a connecting rod 208 is hinged to the connecting seat 207. The connecting rod 208 is hinged to the housing 106 through a connecting column.

[0019] The end face of the worm gear 201 near the wall of the housing 106 is through the housing 106, and the main body 3 is fixedly installed on the lead screw 203 and the slide bar 204.

[0020] Working principle: When using an auxiliary support for galvanometer performance testing, the rotating turntable first drives the rotating shaft 105 to rotate, and then the rotation of the rotating shaft 105 drives the gear 104 to rotate. Since the gear 104 meshes with the rack 103 fixed on the support column 102, the housing 106 is driven to move up and down along the support column 102, thereby realizing the height adjustment of the body 3. A diamond-shaped groove 205 is provided at the end of the rotating shaft 105. The diamond-shaped groove 205 is slidably connected to the diamond-shaped rod 206 on the worm 201 to realize power transmission. When the worm 201 rotates, the worm wheel 202 meshes with the worm 201, driving the worm wheel 202 to rotate. The worm wheel 202 drives the lead screw 203 to rotate through a key connection. The lead screw 203 is threadedly engaged with the housing 106, pushing the body 3 to move laterally along the slide rod 204 to realize horizontal position adjustment. The connecting seat 207 and the connecting rod 208 form a support structure. By pulling the connecting rod 208, the connecting seat 207 is moved horizontally, thereby driving the worm 201 to move horizontally. When the worm 201 moves horizontally, the rhomboid groove 205 separates from the rhomboid rod 206, so that when the turntable is rotated, it can only drive the housing 106 to move up and down. When the connecting rod 208 is pulled to move the connecting seat 207, the rhomboid rod 206 cooperates with the rhomboid groove 205, so that when the turntable is rotated, the housing 106 can move up and down and the body 3 can move horizontally at the same time, thereby completing a series of tasks. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0021] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
