[0046] The placement plate 48 is arranged on the sliding frame 32. A placement groove is provided on the placement plate 48, and a clamping assembly for clamping a workpiece is arranged in the placement groove.

[0047] The clamping assembly includes two clamping plates 37. A fourth slide groove 36 is provided on the bottom of the placement groove, and one end of the clamping plate 37 is slidably arranged in the fourth slide groove 36. A third screw rod 39 is rotatably installed in the fourth slide groove 36, and the screw threads on both sides of the third screw rod 39 are in opposite directions. The two clamping plates 37 are respectively threadedly connected to the two sides of the third screw rod 39. A fifth motor 38 is embedded and fixedly installed in the placement plate 48, and the motor shaft of the fifth motor 38 is fixedly connected to one end of the third screw rod 39. The workpiece to be punched is placed between the two clamping plates 37, the fifth motor 38 is started, and the third screw rod 39 is rotated, so that the two clamping plates 37 are close to each other, and the workpiece is clamped and fixed. The third screw rod 39 is rotated in the opposite direction, and the two clamping plates 37 move away from each other, thereby releasing the clamping of the workpiece, so that the workpiece can be removed.

[0048] Both ends of the placement plate 48 are arc-shaped, and the two ends of the placement plate 48 are named as the first arc end 481 and the second arc end 482 respectively. Both ends of the second arc end 482 are provided with a first clearance groove 47, and the third telescopic rod 44 is rotatably installed in the first clearance groove 47. The telescopic end of the third telescopic rod 44 extends to the outside of the placement plate 48 and is fixedly installed with a second rectangular slider 46. The seventh motor 42 is fixedly installed in the placement plate 48, and the motor shaft of the seventh motor 42 is fixedly connected to the third telescopic rod 44. The seventh motor 42 drives the third telescopic rod 44 to rotate. The axis of the second arc end 482 and the axis of the third telescopic rod 44 are on the same straight line.

[0049] Both ends of the first arc end 481 are provided with a second clearance groove 53, in which the second telescopic rod 43 is rotatably installed, and the telescopic end of the second telescopic rod 43 extends outside the placement plate 48 and is fixedly connected to the first rectangular slider 45. A sixth motor 41 is fixedly installed in the placement plate 48, and the motor shaft of the sixth motor 41 is fixedly connected to the second telescopic rod 43. The sixth motor 41 drives the second telescopic rod 43 to rotate.

[0050] The rotating sleeve 52 is rotatably mounted in the second clearance groove 53. The rotating sleeve 52 is fixedly sleeved with a first gear 40 and a third gear 51, the first gear 40 is located outside the placement plate 48, and the third gear 51 is located in the second clearance groove 53. The second telescopic rod 43 passes through the rotating sleeve 52, but the second telescopic rod 43 does not contact the rotating sleeve 52. The axis of the first arc end 481, the axis of the second telescopic rod 43 and the axis of the rotating sleeve 52 are located on the same straight line. The sliding frame 32 is fixedly connected to a rack 33 meshing with the first gear 40.

[0051] The third gear 51 is meshed with the second gear 50, and an eighth motor 49 is fixedly installed in the placement plate 48, and the motor shaft of the eighth motor 49 is coaxially fixedly connected with the second gear 50. The eighth motor 49 has a self-locking property.

[0052] Both sides of the sliding frame 32 are provided with limiting grooves 34, and the placement plate 48 is arranged between the two limiting grooves 34. The first rectangular sliding block 45 and the second rectangular sliding block 46 are both slidably matched with the limiting grooves 34 on the same side.

[0053] The third telescopic rod 44 and the second telescopic rod 43 are both electric telescopic rods. The second rectangular slider 46 is disengaged from the limiting groove 34 through the third telescopic rod 44, and the first rectangular slider 45 is slidably set in the limiting groove 34 through the second telescopic rod 43, and then the sixth motor 41 is started, and the placement plate 48 rotates around the axis of the sixth motor 41. At the same time, due to the meshing of the first gear 40 and the rack 33, the first rectangular slider 45 slides along the limiting groove 34, and the placement plate 48 moves on the sliding frame 32. The first rectangular slider 45 is disengaged from the limiting groove 34, and the second rectangular slider 46 is located in the limiting groove 34. The seventh motor 42 is started, and the placement plate 48 rotates around the axis of the seventh motor 42. The first rectangular slider 45 and the second rectangular slider 46 are both located in the limiting groove 34, and the eighth motor 49 is started, the second gear 50 rotates, the third gear 51 rotates, and the rotating sleeve 52 rotates, thereby rotating the first gear 40, and the first gear 40 rolls on the rack 33, and then the placement plate 48 moves along the sliding frame 32.

[0054] The supporting platform 1 is in a stepped shape, and a slag dropping trough 2 is provided on the supporting platform 1 .

[0055] Initially, the placement plate 48 is on the first step of the carrier 1, and the first step is at the highest end of the carrier 1. The first step supports the placement plate 48. The first rectangular slider 45 and the second rectangular slider 46 are both located in the limit slot 34. The workpiece to be punched is placed between the two clamping plates 37, and the fifth motor 38 is started to make the two clamping plates 37 approach each other to clamp and fix the workpiece. Then, the first hole is punched on the workpiece by the punching mechanism.

[0056] After the first punching is completed, the punching mechanism is moved to the top of the second step. During the movement of the punching mechanism along the third slide groove 11, the winding wheel 26 releases the line to make the rope 31 loose.

[0057] The second rectangular slider 46 is moved out of the limiting groove 34 by the third telescopic rod 44, and then the sixth motor 41 is started. Since the first rectangular slider 45 is set in the limiting groove 34, it is difficult for the first rectangular slider 45 to rotate, so that the placement plate 48 rotates around the axis of the sixth motor 41. Since the first gear 40 and the rack 33 are engaged, while the placement plate 48 rotates around the axis of the sixth motor 41, the first rectangular slider 45 slides along the limiting groove 34, so that the placement plate 48 slides in the direction close to the second step. The second step is adjacent to the first step and is lower than the first step. During the flipping process of the placement plate 48, the debris on the workpiece falls into the slag trough 2. When the placement plate 48 flips 180 degrees, the workpiece is located below the placement plate 48, and the first arc end 481 is tangent to one side of the second step. That is to say, when the placement plate 48 is not flipped 180 degrees, the first arc end 481 on the placement plate 48 is located on the first step, and the first step supports the placement plate 48, so that the placement plate 48 will not fall.

[0058] After the placement plate 48 turns over 180 degrees, the placement plate 48 and the sliding frame 32 move downward under the action of gravity until the placement plate 48 falls on the second step. The placement plate 48 hits the second step, and when the placement plate 48 contacts the second step, the placement plate 48 suddenly stops moving, and the debris in the hole continues to fall under the action of inertia, so that the debris in the hole is shaken off and falls into the slag chute 2.

[0059] Then, the second rectangular slider 46 is extended into the limiting groove 34 through the third telescopic rod 44, and the first rectangular slider 45 is disengaged from the limiting groove 34 through the second telescopic rod 43. The seventh motor 42 is started, and since the second rectangular slider 46 cannot rotate, the placement plate 48 rotates around the axis of the seventh motor 42, so that the placement plate 48 turns 180 degrees on the second step, and the workpiece is located above the placement plate 48, so that the punching mechanism can perform a second punching process on the workpiece.

[0060] The bottom of the slag trough 2 is provided with a scraper 3 for limited sliding. A first chute 6 is provided on the inner wall of the slag trough 2, a first screw 8 is rotatably installed in the first chute 6, the scraper 3 is threadedly connected to the first screw 8, a first motor 7 is fixedly installed on the inner wall of the slag trough 2, and the first motor 7 is fixedly connected to the first screw 8.

[0061] The support platform 1 is provided with a slag outlet connected to the slag chute 2, and a baffle 5 for blocking the slag outlet is installed on the support platform 1 through the rotation of a rotating rod. A torsion spring is sleeved on the rotating rod, one end of which is fixedly connected to the baffle 5, and the other end of which is fixedly connected to the support platform 1. Under the action of the torsion spring, the baffle 5 blocks the slag outlet. A push rod 4 is fixedly installed on the side of the scraper 3 close to the baffle 5. When the scraper 3 moves in the direction close to the baffle 5, the push rod 4 pushes the baffle 5 open, thereby discharging the debris outside the support platform 1.

[0062] Working principle:

[0063] Initially, the punching mechanism is above the first step, and the placement plate 48 is on the first step. The placement plate 48 is supported on the first step. The first rectangular slider 45 and the second rectangular slider 46 are both in the limit groove 34. The rope 31 is in a tightened state. The scraper 3 is located at the end of the slag trough 2 away from the baffle 5.

[0064] The workpiece to be punched is placed in the placement groove of the placement plate 48, and the workpiece is placed between the two clamping plates 37. The workpiece is clamped and fixed by the clamping plates 37. Specifically, the fifth motor 38 is started, and the fifth motor 38 drives the third screw rod 39 to rotate, and the two clamping plates 37 approach each other, thereby clamping and fixing the workpiece.

[0065] The first punching process is performed on the workpiece by the punching mechanism. Specifically, the third motor 17 is started to rotate the rotating disk 18, so that the required cutter head 20 is placed at the punching station. Then the first telescopic rod 15 is started, the rotating disk 18 and the cutter head 20 move downward, and at the same time, the cutter head 20 at the punching station is rotated by the fourth motor 19, and the cutter head 20 performs the first punching process on the workpiece.

[0066] After the first drilling is completed, the rotating disk 18 is moved upward by the first telescopic rod 15 .

[0067] Then, the second motor 13 is started, the second screw rod 14 rotates, and the first slide block 12 slides along the third slide groove 11, thereby moving the drilling mechanism upward to the second step.

[0068] At the same time, the second screw rod 14 drives the fourth pulley 30 to rotate, and the third pulley 28 is rotated through the second belt 29, and the second rotating shaft 23 is rotated, and then the second pulley 27 is rotated, and the first rotating shaft 22 is rotated under the action of the first belt 25. Then, the four winding wheels 26 are rotated at the same time, and the winding wheels 26 release the corresponding ropes 31, so that the ropes 31 become loose.

[0069] After that, the third telescopic rod 44 is started, and the third telescopic rod 44 drives the second rectangular slider 46 to move out of the limiting groove 34. The sixth motor 41 is started, and since the first rectangular slider 45 is set in the limiting groove 34 and cannot rotate, the placement plate 48 is flipped around the axis of the sixth motor 41 in the direction of the second step. During the flipping of the placement plate 48, due to the meshing of the first gear 40 and the rack 33, the first rectangular slider 45 slides along the limiting groove 34, and the placement plate 48 moves toward the direction close to the second step. During the flipping of the placement plate 48, some debris on the workpiece will fall into the slag trough 2, and some debris will adhere to the hole and cannot fall.

[0070] When the placement plate 48 turns over 180 degrees, the first arc end 481 is tangent to one side of the second step, and the placement plate 48 loses the support of the first step, and the workpiece is now located below the placement plate 48. As the rope 31 becomes loose, the placement plate 48 and the sliding frame 32 fall downward under the action of gravity, and the placement plate 48 falls onto the second step. The placement plate 48 hits the second step, and then the debris in the hole is shaken off into the slag chute 2. The debris in the hole is discharged to prevent the debris from affecting the second drilling process.

[0071] It should be noted that the initial position of the placement plate 48 on the first step should be reasonably set. When the placement plate 48 is not turned over 180 degrees, part of the placement plate 48 is always located on the first step, and the first step has a supporting effect on the placement plate 48, and the placement plate 48 will not fall under its own gravity.

[0072] After that, the second telescopic rod 43 is started to move the first rectangular slider 45 out of the limiting groove 34, and then the second rectangular slider 46 is extended into the limiting groove 34 through the third telescopic rod 44. The seventh motor 42 is started, and since the second rectangular slider 46 is located in the limiting groove 34 and cannot rotate, the placement plate 48 is rotated around the axis of the seventh motor 42, so that the placement plate 48 is turned on the second step in the direction away from the first step. Until the placement plate 48 is turned 180 degrees, the workpiece is located above the placement plate 48.

[0073] Then start the third motor 17 to switch the cutter head 20 so that the required cutter head 20 is at the punching station. Then start the first telescopic rod 15 to move the rotating disk 18 downward and rotate the cutter head 20 at the punching station, thereby performing a second punching process on the workpiece.

[0074] In this way, the drilling process of the workpiece is completed.

[0075] When the punching process is completed, the second motor 13 is started, the second screw rod 14 rotates, and the first slider 12 drives the punching mechanism to move to the initial position. The second screw rod 14 drives the second rotating shaft 23 to rotate through the second belt 29, and the second rotating shaft 23 drives the first rotating shaft 22 to rotate through the first belt 25, thereby rotating the four winding wheels 26, and the winding wheels 26 reel in the rope 31, and the rope 31 drives the sliding frame 32 to move upward.

[0076] After the punching mechanism moves to the initial position, the sliding frame 32 moves to the initial position. Then the first rectangular slider 45 and the second rectangular slider 46 are both in the limiting groove 34. The eighth motor 49 is started, and the eighth motor 49 drives the second gear 50 to rotate, the third gear 51 to rotate, and the first gear 40 to rotate. Since the first gear 40 is engaged with the rack 33, the placement plate 48 moves along the limiting groove 34 toward the direction close to the first step until the placement plate 48 returns to the initial position. Then the placement plate 48 quickly returns to the initial position to facilitate processing of the next workpiece.

[0077] When the slag chute 2 needs to be cleaned, the first motor 7 is started, the first screw 8 rotates, and the scraper 3 pushes the debris to move toward the slag outlet. When the push rod 4 contacts the baffle 5, the push rod 4 pushes the baffle 5 to rotate, thereby moving the debris to the outside of the support platform 1. Then the first motor 7 is reversed to move the scraper 3 to the end of the support platform 1 away from the baffle 5. When the push rod 4 is separated from the baffle 5, the baffle 5 rotates under the action of the torsion spring to block the slag outlet.

[0078] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
