Description

Technical Field

[0001] This utility model relates to the field of laser marking technology, specifically a laser marking and positioning device for metal fixing blocks. Background Technology

[0002] Metal fixing blocks are rigid base components made of metal materials used in fields such as machinery, electronics, and equipment assembly for positioning, supporting, fixing, or connecting other parts. After production, metal fixing blocks need to be laser-marked on their surface. Laser marking uses a high-energy laser beam to change the surface material of the metal, forming permanent and indelible marks, which is crucial for fixing blocks that need to be used for a long time or work in harsh environments.

[0003] For example, the announcement number CN222020870U is a laser marking and positioning device. The device includes a worktable and a laser device installed on the worktable, as well as a cover plate assembly and a fixed base. The cover plate assembly is detachably installed on the fixed base. It mainly solves the problem that the PCB substrate is prone to displacement during marking, which leads to inaccurate marking position of the wireless communication module on the PCB substrate and incomplete label pattern. The above-mentioned device uses a limiting component and a spring to position the substrate so that the substrate is located in the middle of the laser emitter. However, the method of using the spring to move the limiting component cannot guarantee the accuracy of the positioning, and deviation may still occur. Utility Model Content

[0004] The purpose of this invention is to provide a laser marking and positioning device for metal fixing blocks, so as to solve the problem in the background art that the method of using springs to move the limiting components cannot guarantee the accuracy of positioning and that deviation will still occur.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a laser marking and positioning device for a metal fixing block, including a movable plate; Also includes: A sliding groove is integrally formed on the surface of a movable plate, with an open upper end. A bidirectional screw is installed inside the sliding groove, with one end of the bidirectional screw extending outward from the outside of the movable plate. Two sliders are installed inside the sliding groove, located on opposite sides of the sliding groove. A first threaded hole is integrally formed on the surface of each slider, and the first threaded hole is threadedly connected to the bidirectional screw. An L-shaped bracket is installed at the upper end of the slider, with the two L-shaped brackets facing each other. A limiting block is installed on one side of the upper end of the movable plate, located above the sliding groove, and the limiting block slides and engages with one end of the sliding groove. A limiting groove is provided at the bottom of the limiting block, and the external thread on the inner wall surface of the limiting groove is aligned with the internal thread on the surface of the bidirectional screw.

[0006] Preferably, a turntable is provided at one end of the bidirectional screw extending from the movable plate, and the turntable is located on the outside of the movable plate, with a handle provided on one side of the surface of the turntable.

[0007] Preferably, a fixing frame is installed on the upper side of the movable plate, the limiting block is located inside the fixing frame, and the fixing frame is located above one end of the slide groove. The surface of the fixing frame is provided with a second threaded hole, and the upper end of the limiting block is connected to a threaded rod. The threaded rod and the limiting block are connected by a bearing, and the threaded rod is threadedly connected to the second threaded hole. A knob is installed on the upper end of the threaded rod.

[0008] Preferably, a fixed plate is installed below the movable plate, a cylinder is provided at the upper end of the fixed plate, and the upper end of the cylinder is connected to the bottom of the movable plate. A bracket is provided at the bottom of the fixed plate.

[0009] Preferably, the bottom perimeter of the movable plate is provided with auxiliary rods, the surface perimeter of the fixed plate is provided with circular holes, and the bottom of the auxiliary rods is slidably engaged inside the circular holes. The bottom of the auxiliary rods is provided with a limiting plate, and the limiting plate is located below the fixed plate.

[0010] Preferably, a rubber pad is adhered to the inner side of the L-shaped frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting a groove on the surface of the movable plate and installing a bidirectional screw inside the groove, a slider is slidably engaged inside the groove. Two sets of sliders are symmetrically connected to the two ends of the bidirectional screw through threaded holes. An L-shaped frame is installed above the slider. By rotating the bidirectional screw, the L-shaped frame can be moved inward or outward simultaneously. The metal fixing block is placed on the surface of the movable plate. By driving the two sets of L-shaped frames to move inward simultaneously, the metal fixing block can be clamped and positioned to prevent displacement and improve the accuracy of laser marking.

[0012] 2. By setting a limiting block on one side of the slide, the bidirectional screw rotates and drives the L-shaped frame to position the metal fixing block. Then, by turning the knob, the threaded rod rotates, causing the limiting block to descend. The limiting groove on the bottom surface of the limiting block fits into the surface of the bidirectional screw, so that the external thread on the inner wall surface of the limiting groove aligns with the threaded groove on the surface of the bidirectional screw. This limits the bidirectional screw and prevents it from loosening and causing the two sets of L-shaped frames to shift. Attached Figure Description
