Description

Technical Field

[0001] This utility model relates to the field of galvanometer positioning and installation technology, and in particular to a high-precision positioning and installation bracket structure for galvanometers. Background Technology

[0002] A galvanometer is a core device based on the principle of electromagnetic induction. It achieves directional scanning of a laser beam by controlling the rapid and high-precision deflection of a reflecting mirror. It is used in fields such as laser marking, laser welding, 3D printing, medical imaging, and precision measurement. Its performance directly determines the accuracy, speed, and stability of the beam scanning. When using a galvanometer, it needs to be positioned and installed, and then a mounting bracket is needed for fixation.

[0003] Existing positioning and mounting brackets suffer from insufficient rigidity, resulting in poor stability under high-frequency vibration. Due to the excessively thin wall thickness of some brackets, resonance occurs during high-frequency scanning of the galvanometer, causing attenuation of lens amplitude or phase lag, leading to scanning trajectory errors and reducing the galvanometer's effectiveness. Current solutions employ a box-shaped cross-section and reinforcing ribs. Increasing the main body wall thickness of the bracket and incorporating internal cross-shaped reinforcing ribs raises the first-order resonant frequency, avoiding the galvanometer's operating frequency and ensuring increased rigidity. However, insufficient positioning accuracy still exists. Most brackets rely on a single plane or pin for positioning, failing to create three-dimensional constraints. After installation, the galvanometer is prone to slight tilting around its axis, causing beam scanning trajectory deviation and reducing the galvanometer's positioning and installation accuracy. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-precision positioning and mounting bracket structure for galvanometers, aiming to improve the problem that in the prior art, the bracket relies on a single plane or pin for positioning, which does not form a three-dimensional constraint. After the galvanometer is installed, it is easy to tilt slightly around the axis, resulting in the beam scanning trajectory being deviated and reducing the positioning and installation accuracy of the galvanometer.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a high-precision positioning and mounting bracket structure for a galvanometer, comprising a fixed base and a base. Replacement mechanisms are provided on both the left and right sides of the fixed base. A motor shaft is fixedly mounted on the top wall of the fixed base, and a galvanometer mirror is mounted on the top of the motor shaft. A rotating mechanism is provided on the top of the base. The replacement mechanism comprises two upright plates. The bottom of adjacent sides of the two upright plates are respectively fixedly connected to the left and right sides of the fixed base. An electric push rod is fixedly connected to the top of adjacent sides of the two upright plates. One end of the electric push rod is fixedly connected to a mounting shell. Bolts are threadedly connected to the upper and lower ends of the front side of the mounting shell. A positioning clamp is threadedly connected to the end of the bolt. Locking components are provided on the top of both the front and rear sides of the left positioning clamp. Limiting components are provided on the bottom of the opposite sides of the two mounting shells.

[0007] The rotating mechanism includes a rotating column, the top end of which is fixedly connected to the middle of the bottom wall of the fixed base, and the bottom end of which is rotatably connected to the middle of the top wall of the base. A servo motor is fixedly connected to the left side of the bottom wall of the fixed base, and a drive gear is fixedly connected to the output end of the servo motor. A gear housing is fixedly connected to the outer wall of the top wall of the base, and the drive gear meshes with the inner wall of the gear housing. Connecting plates are fixedly connected to both the front and rear sides of the fixed base, and a stabilizing plate is fixedly connected to the bottom of the connecting plate. An annular groove is formed on the outer wall of the gear housing, and adjacent sides of the two stabilizing plates are slidably connected to the annular groove.

[0008] As a further description of the above technical solution:

[0009] The locking assembly includes two locking plates. The left ends of the adjacent sides of the two locking plates are rotatably connected to the front and rear tops of the left positioning clamp, respectively. The front and rear tops of the right positioning clamp are provided with locking grooves, and the right ends of the adjacent sides of the two locking plates are respectively engaged with the corresponding locking grooves.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes two limiting plates. The adjacent sides of the two limiting plates are respectively fixedly connected to the bottom of the opposite sides of the two mounting shells. Limiting grooves are formed in the upper middle part of the adjacent sides of the two upright plates. The outer walls of the two limiting plates are slidably connected to the corresponding limiting grooves.

[0012] As a further description of the above technical solution:

[0013] A control switch is fixedly connected to the right side of the upright plate on the right side. The control switch is electrically connected to the electric push rod and the servo motor respectively.

[0014] As a further description of the above technical solution:

[0015] Two connecting seats are fixedly connected to each of the left and right sides of the base, and a support column is fixedly connected inside each connecting seat.

[0018] As a further description of the above technical solution:

[0019] The replacement mechanism also includes multiple rubber rings, the inner walls of which are respectively fixedly connected to the middle of the bolt.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the displacement of the mounting shell causes the positioning clamps fixed by bolts to move, thereby fixing and clamping the galvanometer lens. At the same time, the locking component locks the two positioning clamps, thereby improving the stability during fixing and ensuring the installation accuracy. Subsequently, the rotation of the bolts allows the positioning clamps to be replaced, so that the positioning clamps can be replaced according to different specifications of galvanometer lenses, thus improving the adaptability of the positioning installation.

[0022] 2. In this utility model, the servo motor is started, which drives the drive gear to rotate. Since the drive gear meshes with the inner wall of the gear housing, the drive gear can drive the fixed seat to rotate around the rotating column as the axis, thereby facilitating the adjustment, maintenance and disassembly angle, thus improving the flexibility during disassembly and assembly. At the same time, the stabilizing plate improves the stability during rotation. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a high-precision positioning and mounting bracket structure for a galvanometer, comprising a fixed base 1 and a base 5. The fixed base 1 is provided with a replacement mechanism 2 on both the left and right sides. The replacement mechanism 2 is used to fix and clamp the galvanometer lens 4, thereby improving the stability of the positioning and mounting. A motor shaft 3 is fixedly mounted on the top wall of the fixed base 1. The galvanometer lens 4 is provided on the top of the motor shaft 3. A rotating mechanism 6 is provided on the top of the base 5. The rotating mechanism 6 is used to increase the flexibility when disassembling and assembling the galvanometer lens 4.

[0032] The replacement mechanism 2 includes two upright plates 201. The bottom of the adjacent sides of the two upright plates 201 are fixedly connected to the left and right sides of the fixed base 1, respectively. The top of the adjacent sides of the two upright plates 201 are fixedly connected to electric push rods 202, so that when the electric push rods 202 are activated, they can drive the mounting shell 203 and the positioning clamp 205 to move, thereby fixing and clamping the galvanometer lens 4. One end of the electric push rod 202 is fixedly connected to the mounting shell 203. The upper and lower ends of the front side of the mounting shell 203 are threaded with bolts 204. The end of the bolts 204 is threaded with the positioning clamp 205. By rotating the bolts 204, the positioning clamp 205 can be disassembled and replaced, thereby achieving the purpose of positioning and installing the galvanometer lens 4 according to different specifications. The top of the front and rear sides of the left positioning clamp 205 are provided with locking components 206, and the bottom of the opposite sides of the two mounting shells 203 are provided with limit components 207.

[0033] The locking assembly 206 includes two locking plates 2061. The left ends of the adjacent sides of the two locking plates 2061 are rotatably connected to the top front and rear sides of the left positioning clamp 205, respectively. The top front and rear sides of the right positioning clamp 205 are provided with locking grooves 2062, so that the overall stability of the two positioning clamps 205 after being fixed can be improved and the shaking can be reduced by the locking plates 2061 engaging with the corresponding locking grooves 2062.

[0034] Specifically, in the replacement mechanism 2, the bottom of the two adjacent upright plates 201 is fixed to the top left and right sides of the fixed base 1, so that when the electric push rod 202 is activated, one end of it can drive the mounting shell 203 to move, so that the positioning clamp 205, which is threadedly installed on the front side of the mounting shell 203 by bolts 204, moves synchronously to fix and clamp the galvanometer lens 4. The positioning clamp 205 can be disassembled and replaced by rotating the bolts 204 to adapt to different specifications of galvanometer lens 4. At the same time, the overall stability can be improved by the locking plate 2061 rotating and engaging with the locking groove 2062. The limiting component 207 on the bottom side of the mounting shell 203 away from each other assists in limiting the position. The galvanometer lens 4 is installed on the top of the motor shaft 3 on the top wall of the fixed base 1. The rotating mechanism 6 on the top of the base 5 increases the flexibility of disassembling and assembling the galvanometer lens 4, and improves the overall positioning and installation stability.

[0035] Reference Figure 1 , Figure 3 and Figure 5 The rotating mechanism 6 includes a rotating column 601. The top end of the rotating column 601 is fixedly connected to the middle of the bottom wall of the fixed base 1, and the bottom end of the rotating column 601 is rotatably connected to the middle of the top wall of the base 5. A servo motor 602 is fixedly connected to the left side of the bottom wall of the fixed base 1, so that the drive gear 603 can rotate when the servo motor 602 is started. The output end of the servo motor 602 is fixedly connected to the drive gear 603. A gear housing 604 is fixedly connected to the outer wall of the top wall of the base 5. The drive gear 603 meshes with the inner wall of the gear housing 604, thereby driving the gear 603 and the gear housing 604 to rotate. The meshing connection of 04 enables the drive gear 603 to drive the fixed seat 1 to rotate around the rotating column 601 as the axis. The front and rear sides of the fixed seat 1 are fixedly connected to the connecting plate 605, and the bottom of the connecting plate 605 is fixedly connected to the stabilizing plate 606. Through the synchronous rotation of the stabilizing plate 606, the rotation of the fixed seat 1 can be restricted by the annular groove 607, thereby improving the stability during rotation and making it easy to adjust, maintain and disassemble the angle of the diaphragm lens 4. The outer wall of the gear seat housing 604 is provided with an annular groove 607, and the adjacent sides of the two stabilizing plates 606 are slidably connected to the annular groove 607.

[0036] Specifically, the top of the rotating column 601 is fixed to the middle of the bottom wall of the fixed base 1, and the bottom is rotatably connected to the middle of the top wall of the base 5. This allows the servo motor 602 to start, which drives the drive gear 603 to rotate. Since the drive gear 603 meshes with the inner wall of the gear housing 604, the fixed base 1 rotates around the rotating column 601. The connecting plate 605 fixed to the front and rear sides of the fixed base 1 and the stabilizing plate 606 fixed at the bottom rotate synchronously with it. The adjacent side of the stabilizing plate 606 is slidably connected to the annular groove 607 opened on the outer wall of the gear housing 604. The annular groove 607 restricts the rotation trajectory of the fixed base 1, improves the rotation stability, and facilitates the adjustment, maintenance, disassembly, and assembly of the diaphragm lens 4.

[0037] Reference Figure 1 , Figure 4 and Figure 5 The limiting component 207 includes two limiting plates 2071. The adjacent sides of the two limiting plates 2071 are respectively fixedly connected to the bottom of the opposite sides of the two mounting shells 203. Limiting grooves 2072 are opened in the upper middle part of the adjacent sides of the two upright plates 201. The outer walls of the two limiting plates 2071 are slidably connected to the corresponding limiting grooves 2072. A control switch 9 is fixedly connected to the right side of the right upright plate 201. The control switch 9 is electrically connected to the electric push rod 202 and the servo motor 602 respectively. The replacement mechanism 2 also includes multiple rubber rings 208. The inner walls of the multiple rubber rings 208 are respectively fixedly connected to the middle of the bolts 204.

[0038] Specifically, by sliding the limiting plate 2071 and the limiting groove 2072 together, the limiting effect of the mounting shell 203 during displacement can be improved, avoiding the shaking during positioning and clamping that would affect the fixation. The control switch 9, which is electrically connected to the electric push rod 202 and the servo motor 602 respectively, can complete the opening and closing of the equipment. The rubber ring 208 can reduce the rotational damage of the bolt 204 to the front side of the mounting shell 203.

[0039] Reference Figure 1 , Figure 2 and Figure 3 Two connecting seats 7 are fixedly connected to the left and right sides of the base 5, and a support column 8 is fixedly connected inside the connecting seat 7; the two positioning clamps 205 are respectively engaged with the inner wall of the corresponding mounting shell 203 on opposite sides, and the two mounting shells 203 are both designed with a concave shape.

[0040] Specifically, the connection between the connecting seat 7 and the support column 8 improves the overall stability of the device during operation. The positioning effect is improved when the positioning clamp 205 is initially fixed by engaging with the inner wall of the corresponding mounting shell 203 on the opposite side of the positioning clamp 205.

[0041] Working principle: By activating two electric push rods 202, one end of each rod drives the mounting shell 203 to move, which in turn moves the positioning clamp 205 connected by bolts 204 to move synchronously, forming a fixed clamp on the galvanometer lens 4 at the top of the motor shaft 3, achieving high-precision positioning and installation. The locking plate 2061, which is rotatably connected to the top of the front and rear sides of the left positioning clamp 205, engages with the locking groove 2062 on the top of the front and rear sides of the right positioning clamp 205 on its adjacent right side, improving the overall stability of the two positioning clamps 205 after fixation and reducing shaking. Then, by rotating the bolts 204, the threaded connection between the bolts 204 and the positioning clamp 205 can be released, completing the disassembly and replacement of the positioning clamp 205 to adapt to different specifications of galvanometer lens 4, expanding the adaptability range of positioning and installation. The limiting component 207 at the bottom of the side of the two mounting shells 203 that is far apart restricts the displacement trajectory. The rotating mechanism 6 at the top of the base 5 increases the flexibility when disassembling and assembling the galvanometer lens 4, thus improving the overall stability and accuracy of positioning and installation.

[0042] Furthermore, the top of the rotating column 601 is fixed to the middle of the bottom wall of the fixed base 1, and the bottom is rotatably connected to the middle of the top wall of the base 5, providing axial support for the rotation of the fixed base 1. When the servo motor 602 is started, it can drive the drive gear 603 to rotate. The drive gear 603 meshes with the inner wall of the gear housing 604. Under the action of meshing transmission, the drive gear 603 drives the fixed base 1 to rotate around the rotating column 601 as the axis, realizing the rotation of the fixed base 1. This facilitates the adjustment of the angle when maintaining and disassembling the diaphragm lens 4. The bottom of the connecting plate 605 fixed on the front and rear sides of the fixed base 1 is fixedly connected to the stabilizing plate 606. The stabilizing plate 606 rotates synchronously with the fixed base 1. Its adjacent side is slidably connected to the annular groove 607 opened on the outer wall of the gear housing 604. The annular groove 607 restricts the movement trajectory of the stabilizing plate 606, thereby improving the stability of the fixed base 1 when rotating. While realizing the angle adjustment to improve the flexibility of disassembly and assembly, it ensures the smoothness of the rotation process.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
