[0011] Preferably, the method for using the automotive parts laser cutting device comprises the following steps:

[0012] S1: After the staff fixes the automobile parts with the clamp, they then control the first electric push rod to drive the horizontal moving seat to slide along the top of the base, and control the second electric push rod to control the vertical moving seat to move along the direction of the slide slot, so as to facilitate the synchronous movement of the first support frame and the second support frame, so that the laser cutting machine and the grinding assembly are synchronously moved to the cutting position, and then the size of the mounting hole is cut according to the needs, and the knob is controlled to work, so as to drive the driving threaded rod to rotate, and then drive the adjustment block to slide along the inner wall of the adjustment box. At this time, the second bevel gear rotates synchronously, driving the first bevel gear and the sleeve engaged therewith to rotate synchronously on the rotating shaft, and driving the driving block to slide on the limit plate through the fixed shaft and the first connecting rod, so as to facilitate the horizontal movement of the laser cutting machine, determine the size of the mounting hole, and after the adjustment is completed, the reciprocating motor is controlled to work, so as to drive the driving disk to rotate under the action of the rotating shaft, thereby driving the adjusting box and the adjusting block to rotate with the driving disk as the center, so that the laser cutting machine can rotate with the driving disk as the center, and at this time, the driving block reciprocates at different distances on the limit plate according to the position of the laser cutting machine;

[0013] S2: When the position of the adjustment block in the adjustment box is adjusted by rotating the knob, the position of the laser cutting machine is adjusted synchronously, and then the first L-shaped toothed rod is driven to mesh with the second gear, so that the first gear is driven to rotate synchronously through the rotating shaft, and then the linkage toothed rod is driven to slide synchronously on the mounting frame, so that one of the matching blocks slides in the moving groove, and then through the cooperation of the articulated rod and the articulated frame, under the action of the sliding sleeve and the moving groove, a plurality of grinding arc plates are driven to adjust with the receiving column as the center, so that the size of the combination of the plurality of grinding arc plates is always consistent with the size of the laser cutting machine rotating with the driving disk as the center under the action of the reciprocating motor;

[0014] S3: Then, by controlling the third electric push rod to work, the locking frame and the driving plate are driven to move downward along the slotting direction synchronously, and then the laser cutting machine is driven downward by the sliding frame. At this time, the delay plate moves downward synchronously, and in the process of moving downward, the two wedge blocks located at the bottom of the slot are squeezed by the delay sleeve, so that under the action of the compression spring and the clamping rod, the two wedge blocks are respectively clamped on both sides of the delay sleeve through the bayonet. At this time, the second L-shaped toothed groove rod drives the matching gear to rotate, and the auxiliary shaft cannot rotate through the set one-way bearing. After the reciprocating motor drives the laser cutting machine to rotate repeatedly for one circle and moves upward under the action of the third electric push rod, the driving plate is driven to move up. At this time, the delay sleeve is still clamped under the wedge block. Under the action of the first spring telescopic rod, the distance between the driving plate and the delay plate gradually increases until the two sides of the locking frame are pressed against the arc plate. The cam-shaped plate contracts under the action of the second spring telescopic rod, so that the two wedge-shaped blocks and the opening are away from the delay sleeve, and then the delay plate moves upward under the action of the first spring telescopic rod, and the second L-shaped toothed rod is provided to drive the matching gear to rotate synchronously, so that the auxiliary shaft rotates, and drives the matching plate to rotate synchronously, and drives the moving rod to move up and down once through the cooperation of the card shaft and the driving rod. When the moving rod located below moves upward, it drives the driving column to move upward along the direction of the driving sleeve, and under the cooperation of the curved slide groove and the fixed rod, the receiving column is driven to slide and rotate upward, and the telescopic spring is compressed synchronously, thereby driving the cross frame and the entire grinding arc plate to rotate and move upward, and drive the linkage toothed rod away from the first gear, and re-engage when resetting, so as to facilitate the grinding of the inner wall of the cutting installation hole, and can be reset to the initial position by the telescopic spring when resetting.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, when the device is used, the staff first fixes the automobile part with a clamp, and then uses the moving component to synchronously move the laser cutting machine and the grinding component to the cutting position, and then cuts the size of the installation hole according to the needs, controls the driving and adjusting component to work, and drives the grinding component to work through the linkage component, so that the grinding end of the grinding component is synchronously adjusted to make it consistent with the cutting size of the laser cutting machine, and then drives the laser cutting machine to move toward the automobile part through the moving component and cuts it. During the movement, through the delay component set, the laser cutting machine drives the matching component to work when it resets away from the automobile part after completing the cutting, thereby driving the adjustment component. The completed grinding component grinds the inner wall of the cut installation hole. In this process, the staff avoids the need to move the grinding tool to the cutting position after the cutting is completed, and then grind the inner wall of the cut installation hole with the grinding tool to complete the cutting work, which simplifies the work steps and improves the convenience at work. At the same time, the grinding end can be adjusted in real time according to the size of the cut installation hole so that it can fit the inner wall of the cut installation hole, thereby improving work efficiency. It is achieved that the inner wall can be automatically polished after the cutting is completed, and the grinding area can be adjusted in real time according to the size of the cut hole to avoid the effect of low convenience and insufficient work efficiency.

[0017] In the present invention, after the staff fixes the automobile parts by the clamp, the staff then controls the first electric push rod to drive the lateral moving seat to slide along the top of the base, and controls the second electric push rod to control the vertical moving seat to move along the direction of the slide slot, thereby facilitating the synchronous movement of the first support frame and the second support frame, so that the laser cutting machine and the grinding assembly are synchronously moved to the cutting position, and then the size of the mounting hole is cut according to the needs, and the knob is controlled to work, thereby driving the driving threaded rod to rotate, and then driving the adjusting block to slide along the inner wall of the adjusting box. At this time, the second bevel gear rotates synchronously, driving the first bevel gear and the sleeve meshing therewith to move synchronously. The laser cutting machine is installed on the limit plate and the drive block is moved back and forth at different distances according to the position of the laser cutting machine, so that the laser cutting machine can cut installation holes of different diameters as needed, thereby improving the practicality of the device.

[0018] In the present invention, when the position of the adjustment block in the adjustment box is adjusted by rotating the knob, the position of the laser cutting machine is adjusted synchronously, thereby driving the first L-shaped toothed rod to mesh with the second gear, thereby driving the first gear to rotate synchronously through the rotating shaft, and then driving the linkage toothed rod to slide synchronously on the mounting frame, so that one of the matching blocks slides in the moving groove, thereby through the cooperation of the hinged rod and the hinged frame, under the action of the sliding sleeve and the moving groove, driving a plurality of grinding arc plates to adjust around the receiving column as the center, so that the size of the combination of the plurality of grinding arc plates is always consistent with the size of the laser cutting machine rotating around the driving disk as the center under the action of the reciprocating motor, so that the grinding end can be adjusted in real time according to the size of the cutting mounting hole. It can fit the inner wall of the installation hole that has been cut to improve work efficiency, and when cutting, it drives the first L-shaped toothed rod to disengage from the second gear, and re-engage after one reciprocating movement, which is convenient for the next cutting, and then controls the third electric push rod to work, thereby driving the locking frame and the driving plate to move downward along the slotting direction synchronously, and then driving the laser cutting machine to move downward through the sliding frame. At this time, the delay plate moves downward synchronously, and in the process of moving downward, the two wedge blocks located at the bottom of the slot are squeezed by the delay sleeve, so that under the action of the compression spring and the clamping rod, the two wedge blocks are respectively clamped on both sides of the delay sleeve through the bayonet, and at this time, the second L-shaped toothed rod drives the matching gear to rotate, and the auxiliary shaft cannot rotate through the one-way bearing provided. After the reciprocating motor drives the laser cutting machine to rotate repeatedly for one circle and moves upward under the action of the third electric push rod, the driving plate is driven to move up. At this time, the delay sleeve is still stuck under the wedge block. Under the action of the first spring telescopic rod, the distance between the driving plate and the delay plate gradually increases until the two sides of the locking frame are pressed against the arc plate. The arc plate contracts under the action of the second spring telescopic rod, so that the two wedge blocks and the opening are away from the delay sleeve, and then the delay plate is moved up under the action of the first spring telescopic rod. The second L-shaped toothed rod is set to drive the matching gear to rotate synchronously, so that the auxiliary shaft rotates, and drives the matching disk to rotate synchronously. Through the cooperation of the card shaft and the driving rod, the moving rod is driven to move up and down once. When the moving rod located below moves upward When moving, the driving column is driven to move upward along the direction of the driving sleeve, and with the cooperation of the curved slide groove and the fixed rod, the receiving column is driven to slide and rotate upward, and the telescopic spring is compressed synchronously, thereby driving the cross frame and the entire grinding arc plate to rotate and move upward, and driving the linkage tooth groove rod away from the first gear, and re-engage when resetting, so as to facilitate the grinding of the inner wall of the cutting installation hole, and can be reset to the initial position by the telescopic spring when resetting. In this process, the need for the staff to move the grinding tool to the cutting position after the cutting is completed, and then grind the inner wall of the cutting installation hole with the grinding tool to complete the cutting work, thereby simplifying the working steps and improving the convenience of work.
