Description

Technical Field

[0001] This utility model relates to the field of auxiliary maintenance technology for laser processing equipment, and in particular to a quick-installation optical path correction tool for the rear end of a Han's Laser machine. Background Technology

[0002] As a high-precision processing equipment widely used in industrial production, the accuracy of the optical path transmission system of Han's Laser machines directly determines the quality and efficiency of cutting or welding. To ensure that the laser beam is accurately transmitted to the center of the processing head, operators need to periodically inspect and calibrate the rear optical path of the equipment. This process typically involves installing dedicated calibration components (such as crosshairs or centering rings) at the optical path exit point. The position of the laser spot is observed to determine any optical path deviation and allow for fine-tuning.

[0003] However, in existing optical path calibration operations, the installation and fixing methods of calibration components generally suffer from insufficient ease of operation. Traditional fixing methods mostly rely on threaded connections, manual clips, or simple screw clamps. Operators need to spend a considerable amount of time manually tightening the fasteners before each calibration and manually disassembling them after calibration. This cumbersome manual operation mode not only significantly increases downtime maintenance time costs and reduces work efficiency when facing frequent debugging needs, but also, in some equipment rear-end areas with limited operating space, manual tightening often fails to ensure consistent force, easily leading to unstable clamping of the calibration components or slight displacement, thereby affecting the reliability of the calibration reference.

[0004] Therefore, this utility model proposes a quick-installation optical path correction tool for the rear end of a Han's Laser machine to address the shortcomings of existing technologies. Utility Model Content

Detailed Implementation

[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] Reference Figures 1-5 This utility model provides an embodiment of a quick-release optical path correction tool for the rear end of a Han's Laser machine. It includes a quick-release assembly 1 as a mounting and driving carrier, and a correction assembly 2 clamped and fixed inside the quick-release assembly 1 to provide an optical path reference. The quick-release assembly 1 achieves rapid locking and releasing of the correction assembly 2 through automated mechanical transmission. Together, they form a complete optical path correction system. The core supporting component of the quick-release assembly 1 is a mounting box 101. The mounting box 101 has a rectangular or cylindrical shell structure. The top of the mounting box 101 is provided with a positioning interface for connecting to the optical path outlet of the Han's Laser machine. This positioning interface specifically adopts a magnetic base or a flange structure with standard threads. A light-transmitting hole is opened at the center of the positioning interface for the laser beam or indicator red light to pass through, allowing... The mounting box 101 can be stably suspended or adsorbed to the rear end of the cutting head of the DaZu laser machine or the end of the optical path transmission channel through the positioning interface, thereby providing a stable physical reference for subsequent optical path correction. The mounting box 101 has a horizontally oriented groove 102 for limiting the movement trajectory. The groove 102 penetrates or partially penetrates the inner cavity of the mounting box 101. The bottom outer wall of the mounting box 101 is fixedly connected to a fixing block 108 by welding or bolt fastening. The fixing block 108 serves as a support platform for the drive source. The side wall of the fixing block 108 is fixedly connected to a motor 107 that provides power by bolts. The output shaft of the motor 107 passes through the fixing block 108 or extends directly to the side and is fixedly connected to a gear 106. The gear 106 can rotate in both directions under the drive of the motor 107, providing the original driving force for the clamping action.

[0028] The quick-installation DaZhu laser machine rear optical path correction tool also includes a toothed plate 105 disposed inside the slide groove 102 and a sliding arm 103 connected to the toothed plate 105. The toothed plate 105 and the aforementioned gear 106 form a tight meshing transmission relationship. Please refer to [the relevant documentation / reference]. Figure 1 and Figure 2 The core drive and clamping structure is described in detail below. The toothed plate 105 is slidably fitted into the internal groove 102 of the mounting box 101. A standard rack structure is machined on the surface of the toothed plate 105 facing the gear 106. The rotation of the gear 106 drives the toothed plate 105 to perform linear reciprocating motion along the length of the groove 102. A sliding arm 103 is fixedly connected to the side wall of the toothed plate 105 by welding or integral molding. The sliding arm 103 passes horizontally through the through hole reserved in the side wall of the mounting box 101 and extends to the outside of the mounting box 101. A first clamping block 104 is fixedly connected to the end of the sliding arm 103 located outside the mounting box 101. The first clamping block 104 serves as a movable clamping end. At the same time, a fixed arm 109 is also fixedly connected inside the mounting box 101. The fixed arm 109 adopts an L-shaped structure made of rigid metal material. The upper end face of the vertical section of the fixed arm 109 is flush with the top of the inner wall of the mounting box 101. The fixing arm 109 is welded and fixed. The horizontal section of the fixing arm 109 extends out of the bottom opening or side wall of the mounting box 101 and is fixedly connected to the second clamping block 110. The second clamping block 110 is set opposite to the first clamping block 104 as a fixed clamping end. The inner side wall of the first clamping block 104 and the inner side wall of the second clamping block 110 are both pasted with anti-slip rubber pads to increase friction and protect the surface of the clamped part. The central axis of the first clamping block 104 and the central axis of the second clamping block 110 are located on the same horizontal plane. When the motor 107 is started, the first clamping block 104 is driven to move towards the second clamping block 110 through the meshing of the gear 106 and the toothed plate 105 until the straightening component 2 is tightly clamped between the two, or the straightening component 2 is released by moving in the opposite direction. This structure of electric gear rack and pinion with double-sided clamping blocks ensures the uniformity of force on the straightening component 2 during the installation process and the repeatability accuracy of the position after installation.

[0029] As a preferred embodiment, in order to construct a stable and high-precision optical path correction physical reference, the overall structure of the correction component 2 includes a high-rigidity connecting body. The connecting body is specifically in the form of a hollow tube or frame structure to ensure unobstructed internal optical path channels. The two ends of the connecting body are respectively fixedly connected to a first correction ring 201 and a second correction ring 204 by welding or integral casting. The first correction ring 201 and the second correction ring 204 are strictly coaxially arranged to ensure correction accuracy. A first square hole 203 is axially opened at the center of the first correction ring 201. A circular hole 202 is radially opened on the side wall of the first correction ring 201, which directly communicates with the interior of the first square hole 203. The inner wall of the circular hole 202 is machined with a standard internal thread. A locking bolt is connected to the interior of the circular hole 202 by thread engagement. The end of the locking bolt can be screwed into and extend into the interior space of the first square hole 203. When the correction copper wire is inserted into the interior of the first square hole 203, the locking bolt can be tightened to firmly press one end of the correction copper wire against the inner wall of the first square hole 203 to achieve fixation.

[0030] In another preferred embodiment, in order to cooperate with the first correction ring 201 to form a straight reference between two points, the center of the second correction ring 204 is provided with a second square hole 205 through it along the axial direction. The central axis of the second square hole 205 is completely coincident with the central axis of the first square hole 203 in space. The second square hole 205 is used to allow the correction copper wire that has passed through the first square hole 203 and been straightened to pass out. Through the cooperation of the first square hole 203 and the second square hole 205, the taut correction copper wire can pass through the entire correction assembly 2 and be located on the geometric central axis of the correction assembly 2, thereby providing a visual physical reference line for the optical path correction of the Han's Laser.

[0031] Working principle: Before using this equipment to perform optical path correction, the baseline of the correction component 2 is first preset and adjusted. One end of the correction copper wire is inserted into the first square hole 203 inside the first correction ring 201, and the locking bolt that fits in the round hole 202 is tightened. The pressure at the end of the bolt is used to press and fix the correction copper wire on the inner wall of the first square hole 203. Then, the correction copper wire is straightened and its other end is passed through the second square hole 205 inside the second correction ring 204. The correction copper wire after passing through is cut or fixed, thereby establishing a visible physical straight line reference between the first correction ring 201 and the second correction ring 204.

[0032] After the adjustment of the correction component 2 is completed, the correction component 2 is placed between the first clamping block 104 and the second clamping block 110 of the quick-release component 1. The motor 107 mounted on the side wall of the bottom fixing block 108 of the mounting box 101 is started. The rotation of the motor 107 drives the gear 106 at the output end to rotate. The gear 106 drives the toothed plate 105 meshing with it to slide linearly in the sliding groove 102 inside the mounting box 101. The toothed plate 105 drives the sliding arm 103 fixed on the side wall to move synchronously, so that the first clamping block 104 connected to the end of the sliding arm 103 moves towards the relatively stationary second clamping block 110.

[0033] When the first clamping block 104 and the second clamping block 110 are respectively attached to the two sides of the correction component 2, the motor 107 stops rotating or maintains torque, and firmly locks the correction component 2 under the mounting box 101. Then, the operator quickly adsorbs or screws the whole device to the optical path exit of the Han's Laser machine through the positioning interface on the top of the mounting box 101, and uses the straight line reference formed by the above-mentioned correction copper wire to adjust the concentricity of the optical path by referring to the laser red light indicator or light spot.

[0034] When the calibration work is completed and disassembly is required, the control motor 107 rotates in the opposite direction, driving the gear 106, toothed plate 105 and sliding arm 103 to move in the opposite direction. The first clamping block 104 moves away from the second clamping block 110 and releases the calibration component 2. At this time, the calibration component 2 can be removed, realizing quick disassembly and assembly. The whole process does not require the use of additional tools to tighten the screws, which improves the maintenance efficiency of the optical path.
