DETAILED DESCRIPTION

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] This embodiment provides an edge trimming device with slag blocking and dust extraction functions, which is specially used for disc workpieces. By using the device of this solution, the circumferential edge of the disc workpiece can be cut while the slag and dust generated by the cutting can be collected.

[0033] Before introducing the equipment of this solution, the disc workpiece structure adapted by this solution is introduced first; for details, see Figure 1-Figure 2The disc workpiece structure adapted by the device includes a chassis 100, which is disc-shaped and has a plurality of positioning holes for fixing the device with bolts; a ring edge 101 is formed at the edge of the chassis 100; the device provided by the present solution can perform processing such as drilling holes, grooving, and chamfering on the ring edge 101.

[0034] For better understanding, this embodiment takes the slotting process as an example. Figure 1-2 As shown, cutouts 102 are formed on the ring edge 101 by laser cutting, and the cutouts 102 are arranged in an array one by one on the ring edge 101 .

[0035] The following is a detailed introduction to the specific composition and structure of this equipment:

[0036] In this solution, the equipment is mainly composed of a rotating platform, an inner push assembly, and a slag stop assembly. The rotating platform is mainly used to rotate the disc workpiece to cooperate with the laser cutter to complete the grooving of the ring edge 101 of the disc workpiece. The inner push assembly is used to fix the disc workpiece, and the slag stop assembly is used to block the slag and dust generated by cutting.

[0037] For details, see Figure 3 The equipment includes a frame 200, a rotating platform 300, an inner push assembly 400, a multi-axis power module 601 and a laser cutter 602, wherein a substrate is fixedly installed on the upper plane of the frame 200, and the substrate will serve as a mounting plate for the rotating platform 300, the inner push assembly 400 and the multi-axis power module 601, so that the rotating platform 300, the inner push assembly 400 and the multi-axis power module 601 are stably fixed to the frame 200, while also ensuring the installation accuracy of the rotating platform 300, the inner push assembly 400 and the multi-axis power module 601.

[0038] See also Figure 4 The rotating platform 300 includes a rotating disk 310, which is mainly used to position the disc workpiece so that the disc workpiece can be initially stabilized and initially fixed on the rotating disk 310; the inner push assembly 400 is provided with a thrust disk 410, which is coaxial with the rotating disk 310, and the thrust disk 410 is used to push the disc workpiece onto the rotating disk 310, so that the disc workpiece is completely fixed;

[0039] The multi-axis power module 601 is fixed on the frame 200, and is composed of three modules: the X-axis, the Y-axis and the Z-axis, and is used to drive the laser cutter 602 to move. The laser cutter 602 is used to cut the edge of the disc workpiece. At the same time, a slag blocking component 500 is also installed on the inner push component 400.

[0040] The disc workpiece is first initially positioned on the rotating disk 310. As the thrust disk 410 gradually approaches, the disc workpiece is pushed against the rotating disk 310. At this time, the disc workpiece is completely fixed under the dual action of the rotating disk 310 and the thrust disk 410. At this time, the slag blocking assembly 500 will be located below the ring edge of the disc workpiece to receive and block the slag.

[0041] See also Figure 5 The rotating disk 310 includes a positioning portion 311 and a group of pin holes 312 arranged on the positioning portion 311. The positioning portion 311 is used to complete the initial positioning of the disc workpiece; a positioning hole is provided at a corresponding position on the disc workpiece, so that when the disc workpiece is placed in the positioning portion 311, the positioning hole is aligned with the pin hole 312, and then the disc workpiece is initially fixed to the positioning portion 311 using bolts or pins; that is, under the joint action of the positioning portion 311 and the pin hole 312, the disc workpiece is positioned and restricted and cannot rotate around its own central axis.

[0042] The thrust plate 410 can just abut against the disc workpiece in the direction of the axis to limit the movement of the disc workpiece.

[0043] See also Figure 5 , Figure 6 The rotating platform 300 further includes a support frame 320, a hollow reducer 330 and a motor 340. The support frame 320 is mounted on the frame 200. The hollow reducer 330 and the motor 340 are both mounted on the support frame 320. The power output shaft of the motor 340 is connected to the power input shaft of the hollow reducer 330. The rotating disk 310 is mounted on the power output shaft of the hollow reducer 330. The rotation of the motor 340 can drive the hollow reducer 330 to work, thereby driving the rotating disk 310 to rotate.

[0044] The rotation of the rotating disk 310 allows the disk workpiece to rotate synchronously, thereby cooperating with the laser cutter 602 to cut the annular edge 101 and form a surrounding incision 102 .

[0045] The inner push assembly 400 also includes a screw module 420 and a bracket 430. The screw module 420 is arranged on the frame 200, and the bracket 430 is located on the slide of the screw module 420. The thrust plate 410 is installed on the bracket 430 through a bearing; the thrust plate 410 can move back and forth along the axial direction under the action of the screw module 420.

[0046] After the disc workpiece is loaded onto the rotating disk 310 and the initial positioning is completed, the screw module 420 drives the thrust disk 410 to approach the rotating disk 310 until the end face of the thrust disk 410 is completely in contact with the end face of the disc workpiece; it should be noted that when cutting, the thrust disk 410 does not withdraw and still presses on the disc workpiece, and the disc workpiece will rotate during cutting, and the thrust disk 410 will rotate with it, so the thrust disk 410 is installed on the bracket 430 through a bearing, so that the thrust disk 410 can rotate freely axially.

[0047] Since the screw module 420 has a large thrust but a slow axial movement speed, when the disc workpiece needs to be replaced for the next time after processing, the screw module 420 is released too slowly. Therefore, in order to increase the processing speed, refer to Figure 7 A second thrust assembly 440 is also provided on the inner push assembly 400. The second thrust assembly 440 includes a cylinder 441, a push plate 442, a guide rail 443 and a slider 444. The cylinder 441 is arranged on the slide of the screw module 420. The push plate 442 is arranged on the telescopic rod of the cylinder 441, and the push plate 442 is fixedly connected to the bracket 430. The guide rail 443 is arranged on the top of the cylinder 441. The slider 444 is assembled on the guide rail 443. The bracket 430 is fixedly arranged on the slider 444. Through the slider 444 and the guide rail 443, the bracket 430 can move axially relative to the cylinder 441. When the cylinder 441 is started, the push plate 442 can push the bracket 430 to move.

[0048] First, the screw module 420 drives the thrust plate 410 to a suitable position close to the rotating disk 310 but not affecting loading and unloading; after the disc workpiece is loaded onto the rotating disk 310 and the initial positioning is completed, the cylinder 441 is started to push the bracket 430 to move, thereby pressing the thrust plate 410 against the disc workpiece to complete the fixation of the disc workpiece; when the processing is completed and needs to be replaced, the cylinder 441 is released to allow the thrust plate 410 to be retracted. The screw and cylinder are used in conjunction, and the cylinder has a fast movement speed, thereby saving the time for loading and unloading.

[0049] See also Figure 7 , Figure 8 The slag blocking assembly 500 includes a support sheet 510 and a slag blocking plate 520. The support sheet 510 is tilted and fixed on the bracket 430. The support sheet 510 is rolled into a slot near one end of the thrust plate 410. The slag blocking plate 520 is movably inserted into the slot on the support sheet 510. When the thrust plate 410 presses the disc workpiece tightly, the slag blocking plate 520 is just below the disc workpiece and the laser cutter 602 to block the slag and debris generated by cutting. The slag blocking plate 520 can move in the slot to adjust to the best position to catch the slag and debris.

[0050] See also Figure 7 , Figure 8 , Fig. 9 The thrust disk 410 includes a thrust copper plate 411 and a connecting pipe 412. The connecting pipe 412 is installed on the bracket 430 through a bearing. The thrust copper plate 411 is arranged on the connecting pipe 412. The thrust copper plate 411 is used to directly contact the disc workpiece; the connecting pipe 412 is a hollow structure, and a group of dust extraction ports 413 are provided on the connecting pipe 412. An exhaust cylinder 450 is also provided on the bracket 430. The exhaust cylinder 450 and the connecting pipe 412 are on the same axis. The bracket 430 has a connecting hole, and the connecting hole is located between the exhaust cylinder 450 and the connecting pipe 412, so that the exhaust cylinder 450 and the connecting pipe 412 are connected. The exhaust cylinder 450 is connected to the exhaust fan through a pipeline, thereby generating negative pressure at the dust extraction port 413.

[0051] The slag blocking plate 520 is installed at an angle. The debris and slag caught by the slag blocking plate 520 will fall to the connecting pipe 412, and will be sucked out of the equipment under the action of negative pressure at the dust extraction port 413, thereby achieving the goal of sucking out the slag and chip slag generated during the cutting process to the outside.

[0052] For ease of understanding, here is a summary of the working process of this device:

[0053] S1: The screw module 420 is started to drive the thrust plate 410 to move toward the rotating plate 310 until the thrust plate 410 is close to the rotating plate 310 but does not affect the proper position of loading and unloading;

[0054] S2: Align the disc workpiece with the positioning portion 311 and the pin hole 312 on the rotating disk 310, and then fix it with bolts or pins, so that the disc workpiece is initially positioned on the rotating disk 310, that is, the axial rotation is restricted;

[0055] S3: The cylinder 441 is started, pushing the thrust plate 410 to press the disc workpiece onto the rotating plate 310, and the disc workpiece is restricted from axial movement. At this time, the disc workpiece is completely fixed; at the same time, the slag blocking plate 520 moves to the bottom of the laser cutter 602 and the ring edge of the disc workpiece;

[0056] S4: The multi-axis power module 601 is started, driving the laser cutter 602 to move to the top of the disk workpiece ring edge 101;

[0057] S5: The motor 340 is started to drive the disc workpiece to start rotating around the axis; at this time, the laser cutter 602 is also started and stopped intermittently, and the ring edge 101 is cut during the rotation of the disc workpiece, so that the incision 102 is formed;

[0058] S6: When the cutting program is started, the external exhaust fan is started, and the slag and debris generated by the cutting fall onto the slag baffle plate 520, slide to the dust extraction port 413, and are sucked out to the outside of the equipment;

[0059] S7: Continue the operation until the cutting of one disc workpiece is completed; the cylinder 441 drives the thrust plate 410 to retreat, and then removes the disc workpiece, and the processing of one disc workpiece is completed; then repeat steps S2-S6 to complete the cutting of another disc workpiece.

[0060] At the same time, if Fig.10 As shown, in this solution, a dust cover can be provided on the frame 200, and the dust cover covers the entire operating space, so that the internal space is closed and plays a dust-proof role.
