Description

Technical Field

[0001] This invention relates to the field of die casting processing technology, specifically to a drilling and tapping device for die castings. Background Technology

[0002] Die casting is a type of pressure-cast part. It is produced by using a pressure casting machine equipped with a casting mold. The molten metal is poured into the feed port of the die casting machine and then pressed to create a part with the shape and size specified by the mold. Such parts are usually called die castings. However, die castings produced in this way will have burrs on the surface, which does not meet the usage requirements. Drilling and tapping are also required according to the requirements.

[0003] In the past, drilling and tapping processes for die castings relied heavily on manual operation or semi-automated equipment. This not only resulted in low production efficiency but also made it difficult to guarantee machining accuracy, failing to meet the demands of large-scale, high-quality production. At the same time, cleaning up the debris generated during processing was tedious and could easily pollute the processing environment, affecting the health of operators. Furthermore, when dealing with die castings of different specifications and shapes, the process of adjusting and changing tooling fixtures was complex, increasing production costs and time.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. Example 1

[0019] Please refer to Figures 1-10 As shown, a drilling and tapping device for die castings includes a base plate 1. A conveying mechanism 2 is mounted on the top of the base plate 1. The conveying mechanism 2 is used to convey the die casting to be processed. A lifting mechanism 3 is provided inside the conveying mechanism 2 to lift the die casting to be processed. Auxiliary mechanisms 4 are installed on both sides of the conveying mechanism 2. A sealing mechanism 5 is connected to the auxiliary mechanism 4. The sealing mechanism 5 is used to seal the die casting to be processed. A clamping mechanism 6 for fixing the die casting is installed inside the sealing mechanism 5. A drilling and tapping mechanism 7 is also installed inside the sealing mechanism 5. The auxiliary mechanism 4 is used to drive the sealing mechanism 5 to tilt and automatically pour out the chips generated during processing. Example 2

[0020] Please refer to Figure 2As shown, the conveying mechanism 2 includes two sets of first threaded rods 202, both ends of which are rotatably connected to the inside of a fixed block 201. The fixed block 201 is fixedly installed on the top of the base plate 1. The threads at both ends of the first threaded rods 202 are in opposite directions, and both ends of the outer walls of the two sets of first threaded rods 202 are threadedly connected to conveyor support plates 207.

Under the action of the belt 206, the two sets of first threaded rods 202 rotate synchronously, thereby causing the two sets of conveyor support plates 207 to move closer or further apart, thus changing the distance between the two sets of conveyor support plates 207. When the die-casting is being processed, the two sides of the die-casting are placed on the two sets of conveyors for transport, and the inner sides of the two sets of conveyor support plates 207 limit the die-casting to prevent it from shifting position during transport. Example 3

[0022] Please refer to Figure 2 and Figure 3 As shown, the lifting mechanism 3 includes a first electric push rod 301 fixedly connected to the inner side of one of the conveyor support plates 207. The output end of the first electric push rod 301 is fixedly connected to the mounting frame 302. A second fixing rod 304 is welded inside the mounting frame 302.

The second threaded rod 303 is rotatably connected inside the mounting frame 302. The threads at both ends of the second threaded rod 303 have opposite directions of rotation. A second servo motor 305 that drives the second threaded rod 303 to rotate is provided on the outer wall of the mounting frame 302.

[0023] Those skilled in the art will understand that by controlling the output end of the first electric push rod 301 to extend or retract, the two sets of clamping members 306 are driven to move upward or downward; and by controlling the output end of the second servo motor 305 to rotate, the second threaded rod 303 is rotated, thereby causing the two sets of clamping members 306 to move closer or further apart. Example 4

[0024] Please refer to Figure 4 and Figure 5 As shown, the auxiliary mechanism 4 includes a first L-shaped plate 401 and a second L-shaped plate 404. The first L-shaped plate 401 and the second L-shaped plate 404 are respectively fixedly connected to the outer sides of two sets of conveyor support plates 207. The inner sides of the first L-shaped plate 401 are fixedly connected to a second electric push rod 402. The output end of the second electric push rod 402 is fixedly installed with a first locking block 403. The inner side of the second L-shaped plate 404 is rotatably connected to a first lead screw 405. A lifting plate 408 is threadedly connected to the first lead screw 405. The lifting plate 408 is slidably connected to the outer wall of the first guide rod 406. The first guide rod 406 is fixedly installed inside the second L-shaped plate 404. A drive motor 409 is provided on the outer wall of the lifting plate 408. A first stepper motor 407 that drives the first lead screw 405 to rotate is installed on the top of the second L-shaped plate 404.

[0025] Those skilled in the art will understand that by controlling the output end of the first stepper motor 407 to rotate, the first lead screw 405 rotates, which drives the lifting plate 408 to move up and down along the outer wall of the first guide rod 406. Example 5

[0026] Please refer to Figure 4 and Figure 5 As shown, the sealing mechanism 5 includes a cover plate 501 located above the first L-shaped plate 401. The cover plate 501 has first slots 502 on both sides, which are adapted to the first locking block 403. The cover plate 501 has a third electric push rod 503 fixedly connected inside both sides. The output end of the third electric push rod 503 is fixedly connected to the second locking block 504. The cover plate 501 has a waste outlet 505. A sealing plate 507 is installed on the front side of the cover plate 501 at a position corresponding to the waste outlet 505. The sealing plate 507 is fixedly connected to the output end of the fourth electric push rod 506, which is installed on the front side of the cover plate 501.

[0027] Please refer to Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, the sealing mechanism 5 also includes a first frame 508 fixedly connected to the output end of the drive motor 409. Several sets of second frames 509 are slidably connected inside the first frame 508. A first cylinder 510 is fixedly installed on the top of the first frame 508. Several sets of second cylinders 511 are slidably connected inside the first cylinder 510. A second stepper motor 513 is provided on the inner wall of the first cylinder 510. The output end of the second stepper motor 513 is fixedly connected to the second lead screw 514. A movable frame 516 is threadedly connected to the second lead screw 514. The movable frame 516 is slidably connected to the second guide rod 515. The second guide rod 515 is welded inside the first cylinder 510.

[0028] Please refer to Figure 7 and Figure 8 As shown, the outer walls of several sets of second cylinders 511 are fixedly connected to several sets of second frames 509 respectively through connectors. The interior of the movable frame 516 is rotatably connected to a first telescopic member 517. One end of the first telescopic member 517 is rotatably connected to the inside of the first cylinder 510, and the other end of the first telescopic member 517 is rotatably connected to the inside of the outermost second cylinder 511. The outermost second frame 509 has a second slot 512 on both sides, and the second slot 512 is adapted to the second slot block 504.

[0029] Those skilled in the art will understand that by controlling the output end of the second stepper motor 513 to rotate, the second lead screw 514 rotates, causing the moving frame 516 to reciprocate along the outer wall of the second guide rod 515. When the moving frame 516 moves forward, it causes the first telescopic member 517 to be in an extended state, thereby causing all the second cylinders 511 to move forward simultaneously, and also causing all the second frame bodies 509 to move forward. Conversely, when the moving frame 516 moves backward, the first telescopic member 517 is in a retracted state, thereby causing all the second frame bodies 509 to move backward. Example 6

[0030] Please refer to Figure 9 As shown, the clamping mechanism 6 includes a fifth electric push rod 601. The fifth electric push rod 601 is provided with two sets of parts that are fixedly installed on the inner side of the cover plate 501 and the inner side of the first frame 508, respectively. The output end of the fifth electric push rod 601 is fixedly connected to a dual-axis electric push rod 602, and both output ends of the dual-axis electric push rod 602 are fixedly connected to clamping blocks 603. Example 7

[0031] Please refer to Figure 10As shown, the drilling and tapping mechanism 7 includes a frame 701, a movable frame 705, a mounting plate 706, and a sliding frame 707. The frame 701 is fixedly installed on the inner wall of the first frame 508. A third servo motor 702 is fixedly connected to the inner wall of the frame 701. The movable frame 705 is provided with two sets of threads respectively threaded to both ends of the outer wall of the third threaded rod 703. The threads at both ends of the third threaded rod 703 have opposite directions of rotation, and the outer end of the third threaded rod 703 is fixedly connected to the output end of the third servo motor 702. A third fixed rod 704 is also fixedly installed inside the movable frame 705, and the movable frame 705 and the third fixed rod 704 are slidably connected.

[0032] Please refer to Figure 10 As shown, the sliding frame 707 is also provided with two sets that are slidably connected to the outer wall of the mounting plate 706. The outer side of the mounting plate 706 is provided with a robotic arm 709. The inner wall of the outermost second frame 509 is provided with a slot for storing a drill bit 710 and a tapping bit 711. The interior of the two sets of sliding frames 707 is rotatably connected to one end of the second telescopic member 708. The other end of the second telescopic member 708 is rotatably connected to the interior of the two sets of movable frames 705.

[0033] Those skilled in the art will understand that by controlling the output end of the third servo motor 702 to rotate, the third threaded rod 703 rotates, causing the two sets of movable frames 705 to move closer or further apart. When the two sets of movable frames 705 move closer together, the second telescopic member 708 is in an extended state, causing the two sets of sliding frames 707 to also move closer together, driving the mounting plate 706 and the robotic arm 709 to move forward as a whole. Conversely, when the two sets of movable frames 705 move further apart, the second telescopic member 708 is in a retracted state, causing the two sets of sliding frames 707 to also move further apart, driving the mounting plate 706 and the robotic arm 709 to move backward as a whole.

[0034] To clearly describe the working principle of this invention, we will use... Figure 1 The following is an explanation of the directional perspective, specifically referring to the "up, down, left, right, front, and back" perspectives mentioned below: S1. By controlling the output end of the first servo motor 204 to rotate, a set of first threaded rods 202 and the wheel 205 rotate as a whole. Under the action of the belt 206, the two sets of first threaded rods 202 rotate synchronously, thereby causing the two sets of conveyor support plates 207 to move closer or further apart, thus changing the distance between the two sets of conveyor support plates 207. When the die-casting part is being processed, the two sides of the die-casting part are placed on the two sets of conveyors for conveying, and the inner sides of the two sets of conveyor support plates 207 limit the die-casting part to prevent it from shifting its position during conveying. S2. When the die-casting part reaches above the lifting mechanism 3, the output end of the first electric push rod 301 is extended by controlling it, so that the two sets of clamping parts 306 are located on the left and right sides of the die-casting part respectively. Then, the output end of the second servo motor 305 is rotated by controlling it, so that the second threaded rod 303 rotates, and then the two sets of clamping parts 306 move closer to each other to clamp the left and right sides of the die-casting part. The output end of the first electric push rod 301 is extended by continuing to drive it, so that the clamped die-casting part is lifted. Then, the output end of the fifth electric push rod 601 inside the cover plate 501 is extended, so that the two sets of clamping blocks 603 are located above and below the front side of the die-casting part. Then, the two output ends of the dual-axis electric push rod 602 are driven to retract synchronously, so that the two sets of clamping blocks 603 move closer to each other to clamp and fix the upper and lower parts of the front side of the die-casting part. The lifting mechanism 3 releases the clamping and resets. S3. By controlling the output end of the second stepper motor 513 to rotate, the second lead screw 514 rotates, which drives the moving frame 516 to move forward along the outer wall of the second guide rod 515, causing the first telescopic member 517 to be in an extended state, thereby driving all the second cylinders 511 to move forward at the same time, and also driving all the second frames 509 to move forward, so that the front side of the outermost second frame 509 fits against the inner side of the cover plate 501. Then, the output ends of the two sets of third electric push rods 503 retract synchronously, so that the two sets of second locking blocks 504 are respectively locked in the second locking slots 512 on both sides of the outermost second frame 509. S4. By controlling the output of the third servo motor 702 to rotate, the third threaded rod 703 rotates, causing the two sets of movable frames 705 to move closer or further apart. The second telescopic member 708 is in an extended or retracted state, driving the mounting plate 706 and the robotic arm 709 to reciprocate back and forth as a whole. In conjunction with the free movement of the robotic arm 709, the drill head 710 can be driven to drill holes in the die-cast part. After drilling is completed, the robotic arm 709 puts the drill head 710 back. The tapping head 711 in another set of slots is clamped and tapped inside the drilled hole. It is worth noting that if it is necessary to drill holes in the clamping parts of the two sets of clamping blocks 603 on the front side, the two sets of clamping blocks 603 inside the first frame 508 clamp and fix the upper and lower parts of the rear side of the die casting, while the two sets of clamping blocks 603 on the front side are released. In this way, the previously blocked parts can be drilled and tapped without the need for adjustment by the staff, which is convenient and quick. S5. After drilling and tapping are completed, the output ends of the two sets of second electric push rods 402 extend synchronously, causing the two sets of first locking blocks 403 to disengage from the first locking slots 502 on both sides, thereby releasing the clamping of the cover plate 501. At this time, the cover plate 501 is only connected to the outermost second frame 509. Next, the output end of the first step motor 407 is driven to rotate, causing the first lead screw 405 to rotate, which drives the lifting plate 408 to move upward along the outer wall of the first guide rod 406. Then, the output end of the drive motor 409 is controlled to move upward. The rotation of the first frame 508, all the second frames 509, and the cover plate 501 rotate as a whole, causing the front side of the outermost second frame 509 to tilt downward. It is worth noting that the inner edges of all the second frames 509 are inclined surfaces. The purpose of this is to allow the debris to slide to the front side of the inner side of the outermost second frame 509 under the action of gravity for collection. Finally, the output end of the fourth electric push rod 506 is driven to retract, causing the sealing plate 507 to move downward, thereby realizing the automatic discharge of debris from the waste outlet 505. S6. After the die casting is processed, the auxiliary mechanism 4 and the sealing mechanism 5 are reset, and then the lifting mechanism 3 puts the die casting back onto the two sets of conveyors for transport. The whole process is automated and requires no manual operation.
