[0001] This utility model relates to the field of laser positioners for machine tools, and in particular to a laser positioner for machine tools. Background Technology

[0002] A laser positioner for machine tools is an auxiliary device used to improve machining accuracy and efficiency. It helps operators or automated systems accurately position the workpiece by emitting a high-precision laser beam. These positioners are widely used on various machine tools, such as lathes, milling machines, and grinding machines, and are particularly important in applications requiring high-precision and repeatable positioning.

[0003] Existing positioners typically use a fixed laser emitter head, providing a baseline in only one direction. They cannot adapt to changes in workpiece shape or processing path in real time. Furthermore, existing positioners may experience internal component failures during prolonged use, requiring maintenance and repair. In such cases, the positioner is only connected to the machine tool support by bolts, necessitating the user to unscrew multiple sets of bolts one by one. This installation and disassembly is inconvenient, time-consuming, and labor-intensive, reducing work efficiency. Therefore, a laser positioner for machine tools is proposed to solve these problems. Utility Model Content

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

[0013] The drive mechanism also includes a guide rod, which is fixedly connected to the surface of the machine tool body, and the outer wall of the guide rod is slidably connected to the interior of the moving block.

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

[0015] The laser positioner is fixedly connected to the mounting plate by fixing bolts.

[0016] As a further description of the above technical solution:

[0017] The limiting block is L-shaped.

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

[0019] The number of the card blocks is set to two sets, and the two sets of card blocks are fixedly connected to the side of each other that is far apart.

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

[0021] 1.

Disassembly can be performed without tightening bolts, thus improving work efficiency.

[0022] 2. In this utility model, by equipping a drive mechanism in both the X and Y axes, precise position adjustment within the plane of the laser positioner can be achieved. The stepper motor can precisely control the rotation angle of the output shaft, drive the reciprocating lead screw to rotate, and make the moving block perform precise linear displacement, thereby achieving high-precision planar positioning and improving the repeatability of workpiece processing.

[0029] 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.

[0030] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a laser positioner for machine tools, including a machine tool body 1. Drive mechanisms 2 are provided on the right and rear sides of the machine tool body 1. Two sets of drive mechanisms 2 are provided to form planar positioning in the X and Y axes. A positioning mechanism 8 is provided on the top of the drive mechanism 2. The positioning mechanism 8 includes a laser positioner 9 and a base plate 12. A mounting plate 10 is fixedly connected to the bottom of the laser positioner 9. The laser positioner 9 utilizes the linearity and stability of the laser beam to provide high-precision positioning. The laser positioner 9 is fixedly connected to the mounting plate 10 by fixing bolts 11. The mounting plate 10 is used to fix the laser emitter head at an appropriate position on the machine tool to ensure its stability and accuracy.

[0031] Reference Figure 2 - Figure 4A limiting block 13 is fixedly connected to the bottom of the mounting plate 10. The limiting block 13 is L-shaped. The top of the base plate 12 is provided with a limiting groove 14 that cooperates with the limiting block 13. The limiting block 13 is inserted into the inner wall of the limiting groove 14. A locking block 15 with a rectangular cross-section is slidably connected to the inner wall of the base plate 12. The locking block 15 is elastically connected to the inner wall of the base plate 12 by a return spring 17. The return spring 17 is provided so that it can be pressed against the inside of the slot 18. At this time, the mounting plate 10 and the base plate 12 are fixed. The surface of the limiting block 13 is provided with a slot 18. The number of locking blocks 15 is set to two sets. The two sets of locking blocks 15 are fixedly connected to the side away from each other with a pull ring 16 for easy pulling of the locking block 15. The locking block 15 is pulled out from the slot 18 by the pull ring 16, which can quickly install and remove the laser positioner 9 and is easy to install on different types of machine tools.

[0032] Reference Figure 1 The drive mechanism 2 includes a stepper motor 3, which is fixedly connected to the surface of the machine tool body 1. The stepper motor 3 can precisely control the rotation angle of the output shaft, thereby improving the control accuracy. The drive mechanism 2 also includes a reciprocating lead screw 4, one end of which is fixedly connected to the output shaft of the stepper motor 3, and the other end of which is rotatably connected to the surface of the machine tool body 1. The operation of the stepper motor 3 causes the reciprocating lead screw 4 to rotate.

[0033] Reference Figure 1 The drive mechanism 2 also includes a moving block 5, which is disposed on the surface of the reciprocating lead screw 4. The rotation of the reciprocating lead screw 4 causes the moving block 5 to move linearly in the axial direction of the reciprocating lead screw 4. A vertical rod 7 that provides support is fixedly connected to the top of the moving block 5. The top of the vertical rod 7 is fixedly connected to the top of the base plate 12. The drive mechanism 2 also includes a guide rod 6 for guiding the displacement direction of the moving block 5, so that the moving block 5 can move linearly more accurately. The guide rod 6 is fixedly connected to the surface of the machine tool body 1, and the outer wall of the guide rod 6 is slidably connected to the inside of the moving block 5.

[0034] Working principle: In use, the workpiece to be processed is fixed on the machine tool, and then the laser positioner 9 is fixed to the mounting plate 10 by fixing bolts 11. Then, the L-shaped limiting block 13 at the bottom of the mounting plate 10 is inserted into the limiting groove 14 at the top of the base plate 12, and the reset spring 17 pushes the locking block 15 into the locking groove 18, thereby firmly fixing the mounting plate 10 and the base plate 12 together. The drive mechanism 2 is started, and the position of the laser positioner 9 is adjusted by the stepper motor 3 and the reciprocating screw 4 system until the laser point or line accurately indicates the required processing position, realizing planar positioning in the X and Y axis directions. According to the processing requirements, the stepper motor 3 is instructed to rotate by the control system, which drives the reciprocating screw 4 to rotate, so that the moving block 5 moves along the X or Y axis direction, thereby adjusting the position of the laser positioner 9. When the laser positioner 9 moves to the predetermined position, the laser positioner 9 is turned on, and the laser positioner 9 emits a laser beam, projecting laser points or lines on the surface of the workpiece. The operator can intuitively and conveniently perform precise processing operations on the workpiece based on these laser markings.

[0035] When it is necessary to disassemble or reinstall the laser positioner 9, the locking block 15 can be pulled by the pull ring 16 to disengage it from the slot 18, so that the mounting plate 10 and the laser positioner 9 can be quickly disassembled. This allows the laser positioner 9 to be installed on different types of machine tools, improving the versatility and flexibility of the equipment.

[0036] 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.
