Description

Technical Field

[0001] This utility model relates to the field of workpiece positioning technology in machining centers, and in particular to a laser positioning system for workpieces in machining centers. Background Technology

[0002] In the field of machining, especially in the application of precision machining centers, rapid and accurate workpiece positioning is a key link in ensuring machining quality and improving production efficiency. Traditional workpiece positioning methods usually rely on mechanical positioning systems, such as locating pins, mechanical stops, or special fixtures. Although these mechanical positioning methods are simple in structure, they have obvious limitations in practical applications: their positioning accuracy is directly limited by the machining accuracy and assembly accuracy of the fixture itself, as well as the repeatability accuracy of the mechanical system. Achieving high-precision positioning is often very difficult, and adjustments are cumbersome and inefficient. Especially when dealing with complex workpieces or requiring multiple batches or small-volume processing, traditional mechanical positioning methods lack flexibility and are difficult to adapt to the requirements of modern intelligent manufacturing for flexibility and efficiency.

[0034] To fully understand the purpose, features and effects of this utility model, the following specific embodiments will be used to describe this utility model in detail, but this utility model is not limited thereto.

[0035] like Figures 1 to 3 As shown, the present invention provides a workpiece laser positioning system for a machining center, comprising a worktable 1, a transverse drive device 2, a longitudinal drive device 3, a moving carriage 4, and a laser positioner 5.

[0036] The top surface of the worktable 1 has a receiving groove 11 extending along its length, and two symmetrically arranged connecting seats 12 are fixed at one end of the worktable 1. A through groove 13 is formed on the side of the receiving groove 11 near the connecting seat 12. In use, the worktable 1 is placed below the machining center.

[0037] A transverse drive device 2 is mounted on the worktable 1 and is used to drive the moving carriage 4 to move laterally. The transverse drive device 2 includes a lead screw 21, a first motor 22, and a slider 23. The two ends of the lead screw 21 are rotatably connected to the connecting seat 12, the output shaft of the first motor 22 is coaxially fixedly connected to the lead screw 21, and the slider 23 is threadedly connected to the lead screw 21 and is slidably inserted into the through groove 13.

[0038] The longitudinal drive device 3 is mounted on the transverse drive device 2 and is used to drive the mobile vehicle 4 to move longitudinally. The longitudinal drive device 3 is a drive cylinder that extends along the length of the receiving groove 11. The fixed end of the drive cylinder is fixedly connected to the slider 23, and the movable end of the drive cylinder is fixedly connected to the mobile vehicle 4.

[0039] A movable carriage 4 is slidably mounted on the worktable 1 to carry the workpiece to be processed. The movable carriage 4 includes a carriage body 41, a rotating shaft 42, vertical rods 43, a universal rotating ball 44, a top plate 45, and a second motor 48. The carriage body 41 is set in the receiving groove 11, and universal wheels 46 are fixedly installed at the bottom of the carriage body 41. The carriage body 41 is fixedly connected to the moving end of the drive cylinder. The rotating shaft 42 is rotatably mounted on one corner of the top surface of the carriage body 41 via bearings, and a first gear 47 is coaxially fixed to the rotating shaft 42. Multiple vertical rods 43 are fixedly arranged at equal intervals along a curved array on the top surface of the carriage body 41, with gaps between the vertical rods 43 and the rotating shaft 42. The universal rotating ball 44 is rotatably embedded in the top of the vertical rods 43. One corner of the top plate 45 is fixedly connected to the top of the rotating shaft 42, and the bottom surface of the top plate 45 is rollingly connected to the universal rotating ball 44. The second motor 48 is fixed on the top surface of the vehicle body 41. The second motor 48 is located between the rotating shaft 42 and the vertical rod 43. The output shaft of the second motor 48 is coaxially fixed with a second gear 49 that meshes with the first gear 47.

[0040] In practical work, the top surface of the top plate 45 should also be fixed with a fixture for fixing the workpiece to be processed. This fixture can be any existing technology, and this application does not limit it.

[0041] A laser positioner 5 is mounted on the mobile vehicle 4 and the worktable 1 for positioning the mobile vehicle 4. Further, the laser positioner 5 includes a first laser emitter 51, a first laser receiver 52, a second laser emitter 53, and a second laser receiver 54. Both the first laser emitter 51 and the second laser emitter 53 are embedded in the receiving groove 11. The first laser receiver 52 is fixed to the vehicle body 41 and is used in conjunction with the first laser emitter 51. The second laser receiver 54 is fixed to the top plate 45 and is used in conjunction with the second laser emitter 53.

[0042] In use, the first motor 22 is started, which drives the lead screw 21 to rotate. The rotation of the lead screw 21 causes the slider 23 to slide, thereby driving the longitudinal drive device 3 to move laterally within the receiving groove 11, further enabling the moving carriage 4 to move laterally within the receiving groove 11 and adjusting the lateral position of the moving carriage 4. The longitudinal drive device 3 is then started, extending or shortening to adjust the longitudinal position of the moving carriage 4 within the receiving groove 11. This continues until the position of the moving carriage 4 is appropriate, i.e., the first laser receiver 52 can receive the laser signal emitted by the first laser emitter 51. At this point, the lateral drive device 2 and the longitudinal drive device 3 are no longer adjusted, and the position of the moving carriage 4 is fixed.

[0043] At this point, if the second laser receiver 54 can receive the signal from the second laser emitter 53, it indicates that the workpiece position is appropriate and no further adjustment is needed. Otherwise, the second motor 48 is started, which drives the second gear 49 to rotate. The second gear 49 drives the first gear 47 to rotate, the first gear 47 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives the top plate 45 to rotate, thereby adjusting the rotation of the top plate 45 and the workpiece on it until the second laser receiver 54 can receive the laser signal emitted by the second laser emitter 53, at which point the adjustment stops. At this point, the workpiece is in the predetermined position.

[0044] Finally, it should be noted that the above-listed embodiments are merely preferred embodiments of the present invention. Of course, those skilled in the art can make modifications and variations to the present invention. If such modifications and variations fall within the scope of the claims of the present invention and their equivalents, they should be considered as being within the protection scope of the present invention.
