Technical Field

[0001] This invention relates to the field of laser inspection technology, and in particular to a laser tracking and inspection device based on a large machining center assembly. Background Technology

[0002] The precision and precision stability of machine tools are important technical indicators. Among existing technologies, laser interferometry is a common error compensation method for CNC machine tools. This is because laser interferometry is widely used in machine tool error compensation, but its detection cycle is relatively long. Essentially, it is a revolutionary tool that transforms "assembly art" into "assembly science." Through high-precision, wide-range, and dynamic three-dimensional spatial measurement, combined with digital twin comparison, it provides "real-time precision navigation" for assembly, making the precision debugging process of large and complex machine tools quantifiable, predictable, and traceable. It is an indispensable standard configuration for top machine tool manufacturers when assembling high-end models.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0037] Reference Figure 1-9 A laser tracking and detection device based on a large machining center assembly includes a support leg 1 and a movable crossbeam 2 mounted on the support leg 1. One end of the movable crossbeam 2 is equipped with a clamping member 3, and the other end of the clamping member 3 is equipped with a switching component 4. The top of the switching component 4 is equipped with a laser detection head 5 for detection. The switching component 4 includes a support arm 41, one end of which is equipped with a top plate 43 for supporting the laser detection head 5. The bottom end of the top plate 43 is equipped with a transmission member 42, and the bottom end of the transmission member 42 is equipped with a conductive member 44. The transmission member 42 is connected to a driving member 45. When the driving member 45 drives the conductive member 44 to a fixed position, the laser detection head 5 has two states: In the first state, the conductive member 44 is separated from the support leg 1, and the transmission member 42 limits the laser detection head 5 to the movable crossbeam 2 and is used to detect the movement of the movable crossbeam 2 on the support leg 1; In the second state, the conductive member 44 is in contact with the support leg 1, and the transmission member 42 separates the laser detection head 5 from the movable crossbeam 2, and the flatness of the support leg 1 surface is detected by the movement of the movable crossbeam 2.

[0038] Specifically, the support leg 1 is composed of multiple connected components. The movable crossbeam 2 on the support leg 1 is driven by its own drive mechanism to move laterally along the support leg 1, allowing the equipment mounted on the movable crossbeam 2 to move laterally on the track 11 erected on the support leg 1. A clamping component 3, fixed on the movable crossbeam 2, is detachably connected to a switching assembly 4. When the drive component 45 in the switching assembly 4 drives the transmission component 44 downwards, the transmission component 44 comes into contact with the upper surface of the support leg 1 and, through the transmission component 42, causes the laser detection head 5 to separate from the movable crossbeam 2. During the movement of the movable crossbeam 2 along the support leg 1, the transmission component 44 transmits the flatness of the support leg 1 surface to the laser detection head 5 via the transmission component 42. The amplitude of the sway of the laser detection head 5 transmits the data. Feedback is sent to the collection plate to detect the flatness of the support leg 1 surface. When the drive component 45 drives the transmission component 44 to reset, the transmission component 44 separates from the surface of the support leg 1. At the same time, the transmission component 42 drives the laser detection head 5 to lock with the directional rod 4201 fixed to the transmission component 42, so that the laser detection head 5 is fixed on the moving crossbeam 2 and moves with the moving crossbeam 2 to synchronously detect the stability of the moving crossbeam 2 on the support leg 1. This device switches the fixing method of the laser detection head 5 between the support leg 1 and the moving crossbeam 2 by driving the transmission component 44 to switch the direction of movement. This enables the laser detection head 5 to detect the stability of the moving crossbeam 2 itself. At the same time, the flatness of the upper surface of the support leg 1 is detected by the transmission component 44, avoiding the cumbersome process of heavy machine tool equipment and improving the convenience of detection.

[0039] A transmission component 42 is fixedly connected to one end of the support arm 41. An inner cylinder 421 is movably connected inside the transmission component 42. A guide block 423 is fixedly connected inside the inner cylinder 421. A gear block 422 is provided at the top of the guide block 423. A lower rack 424 and an upper rack 425 are respectively meshed at both ends of the gear block 422. A top plate 43 is fixedly connected to the top of the upper rack 425. A limiting groove 431 is opened at one end of the top plate 43. A bracket 51 is fixedly connected to the top of the top plate 43, and a laser detection head 5 is fixedly connected to the top of the bracket 51. The lower rack 424 is fixedly connected to the bottom end of the upper support plate 441, and the bottom end of the upper support plate 441 is fixedly connected to the bottom end of the upper support plate 443. The upper support plate 441 is symmetrically provided with limiting rods 445 at both ends, and the bottom end of the limiting rods 445 is provided with a lower support plate 442. The bottom end of the lower support plate 442 is fixedly connected to the bottom end of the lower support plate 447, and the bottom end of the connecting block 447 is movably connected to the contact wheel 448. The top end of the lower support plate 442 is fixedly connected to the top end of the lower support plate 444, and the limiting rod 445 is fitted with a tension spring 446, which is located on the upper support plate. Between 441 and the lower support plate 442; the driving component 45 includes an air pump 451, the bottom end of which is provided with a pneumatic rod 452, and the bottom end of the pneumatic rod 452 is fixedly connected to a positioning block 453. One end of the positioning block 453 is rotatably connected to a support shaft 454; one end of the support shaft 454 is fixedly connected to a gear 455, one end of which meshes with a rack 4551, and the top end of the rack 4551 is fixedly connected to the support arm 41; the end of the gear 455 away from the support shaft 454 is fixedly connected to a rotating... The turntable 456 has a fixed lug 457 symmetrically fixed to one end, a slide rod 458 fixed between the two fixed lugs 457, a slider 459 slidably connected between the two slide rods 458, an eccentric shaft block 4510 fixed to one end of the slider 459, and the eccentric shaft block 4510 is located between the first abutment block 443 and the second abutment block 444; the top of the support leg 1 is symmetrically provided with a track 11, a limiting groove 12 is provided between the two tracks 11, and a contact wheel 448 is provided in the limiting groove 12.

[0040] Specifically, the transmission component 42, which is fixed to one end of the support arm 41, has a cylindrical structure. Inside the inner cylinder 421, which is slidably connected to the transmission component 42, an upper rack 425 and a lower rack 424 are meshed via a gear block 422. Driven by the driving component 45, the lower rack 424 drives the upper rack 425 to reciprocate. The upper support plate 441, to which the lower rack 424 is fixed, is connected to the lower support plate 442 via a limiting rod 445. The upper support plate 441 and the lower support plate 442 are limited by a tension spring 446. When the upper support plate... When the eccentric shaft between the first abutment block 443 fixed to the 441 and the second abutment block 444 fixed to the lower support plate 442 rotates, the eccentric shaft will move the second abutment block 444 downward, so that the bottom end of the second abutment block 444, which is rotatably connected to the connecting block 447, abuts against the limiting groove 12 opened on the upper surface of the support leg 1. Meanwhile, the air pump 451 in the driving component 45 drives the pneumatic rod 452 to move the positioning block 453 downward. The support shaft 454 rotatably connected to the positioning block 453 is fixed... The gear 455 moves downward along the rack 4551, causing the gear 455 to rotate and simultaneously driving the turntable 456 to rotate. The turntable 456 rotates through the eccentric shaft seat fixed to the slider 459, causing the eccentric shaft seat to press the contact wheel 448 against the support leg 1. When there is a height difference in the limiting groove 12 of the support leg 1, the contact wheel 448 transmits the force to the eccentric shaft seat through the abutment block 444 fixed to the connecting block 447. The slider 459, fixed to one end of the eccentric shaft seat, slides on the slide rod 458. The eccentric shaft seat applies upward or downward force to the second abutment 444 via the slider 459 along the slide rod 458, causing the first abutment 443, which is attached to the top of the eccentric shaft seat, to drive the lower rack 424, which is fixed to the upper support plate 441, to move upward. This causes the lower rack 424 to drive the upper rack 425, which is meshed with the gear block 422, to move the laser detection head 5, which is fixed to the top plate 43. This allows the laser detection head 5 to detect the flatness of the surface of the support leg 1 by moving the contact wheel 448 on the upper surface of the support leg 1 through the height difference.

[0041] The clamping component 3 includes a positioning plate 31, a hydraulic pump 32 is fixedly connected to one end of the positioning plate 31, a telescopic rod 33 is provided at one end of the hydraulic pump 32, a movable clamping plate 34 is fixedly connected to one end of the telescopic rod 33, a sliding groove 35 is provided at one end of the movable clamping plate 34, and a support arm 41 is slidably provided in the sliding groove 35.

[0042] Specifically, the positioning plate 31 is engaged with one side of the moving crossbeam 2. The movable clamping plate 34, which is fixed to the telescopic rod 33 driven by the hydraulic pump 32 fixed on the positioning plate 31, is tightened, so that the positioning plate 31 and the movable clamping plate 34 clamp and fix it on the moving crossbeam 2. This facilitates the support arm 41 connected to the movable clamping plate 34 to support the laser detection head 5, thereby improving the ease of installation of the laser detection head 5.

[0043] Working principle: The moving crossbeam 2 on the support leg 1 is driven by its own drive mechanism to move laterally along the support leg 1, allowing the equipment mounted on the moving crossbeam 2 to move laterally on the track 11 erected on the support leg 1. The clamping member 3, which is fixed on the moving crossbeam 2, is detachably connected to the switching component 4, which is mounted on the moving crossbeam 2. When the drive component 45 in the switching component 4 drives the transmission component 44 to move downward, the transmission component 44 comes into contact with the upper surface of the support leg 1, and through the transmission component 42, it causes the laser detection head 5 to separate from the moving crossbeam 2. During the movement of the crossbeam 2 along the support leg 1, the transmission component 44 transmits the flatness of the support leg 1 surface to the laser detection head 5 through the transmission component 42. The data is fed back to the collection plate by the shaking amplitude of the laser detection head 5, realizing the detection of the flatness of the support leg 1 surface. In the drive component 45, the air pump 451 drives the pneumatic rod 452 to drive the positioning block 453 to move downward. The gear 455 fixed on the support shaft 454 rotatably connected to the positioning block 453 moves downward along the rack 4551, so that the gear 455 rotates and drives the turntable 456 to rotate. The turntable 456 rotates through the sliding... The eccentric shaft seat fixed to block 459 rotates, causing the eccentric shaft seat to press the contact wheel 448 against the support leg 1. When there is a height difference in the limiting groove 12 of the support leg 1, the contact wheel 448 is transmitted to the eccentric shaft seat through the second abutment block 444 fixed to the connecting block 447. The slider 459 fixed to one end of the eccentric shaft seat slides on the slide rod 458. The eccentric shaft seat transmits the upward or downward force of the second abutment block 444 through the slider 459 to move directionally along the slide rod 458, causing the first abutment block 443 attached to the top of the eccentric shaft seat to drive the lower rack 424 fixed to the upper support plate 441 to move upward, causing the lower rack 424 to move upward. The upper rack 425, which meshes with the gear block 422, drives the laser detection head 5 fixed to the top plate 43 to move. This allows the laser detection head 5 to detect the flatness of the support leg 1 surface by moving the contact wheel 448 on the upper surface of the support leg 1 through the height difference. When the drive component 45 drives the transmission component 44 to reset, the transmission component 44 separates from the surface of the support leg 1. At the same time, the transmission component 42 drives the laser detection head 5 to lock with the orientation rod 4201 fixed to the transmission component 42, so that the laser detection head 5 is fixed on the moving crossbeam 2 and moves with the moving crossbeam 2 to synchronously detect the stability of the moving crossbeam 2 on the support leg 1.
