DETAILED DESCRIPTION

[0022] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0023] Example:

[0024] Reference Figures 1 to 4 The utility model discloses a positioning punching device for processing guardrail plates, comprising a placing table 1, on which the guardrail plates are placed, and a rectangular frame 2, wherein two vertical sections of the rectangular frame 2 slide through the placing table 1, and two electric push rods 3 are fixedly connected between the inner top wall of the rectangular frame 2 and the top surface of the placing table 1, and a plurality of punching blocks 4 are fixedly connected to the inner top wall of the rectangular frame 2, and a through hole 5 is opened on the top surface of the placing table 1 directly below the punching block 4.

[0025] A plurality of motors 6 are fixedly connected to the inner bottom wall of the rectangular frame 2, and a rotating disk 7 is transmission-connected to the output end of the motor 6. A grinding disk 8 is fixedly connected to the top of the rotating disk 7. The grinding disk 8 is inserted into the corresponding through hole 5, and the top surface of the grinding disk 8 is coplanar with the top surface of the placement table 1.

[0026] A plurality of positioning parts 9 are provided in the placement table 1 .

[0027] In this embodiment, in the initial state (such as Figure 1 and Figure 2 As shown), the stamping block 4 is located above the placement table 1, the grinding disc 8 is located in the through hole 5, and the outer peripheral surface of the grinding disc 8 is in contact with the inner wall of the through hole 5, and the top surface of the grinding disc 8 is coplanar with the top surface of the placement table 1.

[0028] When the guardrail plate needs to be processed, the guardrail plate is placed on the top of the placement table 1, and the guardrail plate is positioned and fixed by the positioning part 9. Then the electric push rod 3 works to drive the rectangular frame 2 to move downward, and the rectangular frame 2 drives the punching block 4, the motor 6, the rotating disk 7 and the grinding disk 8 to move downward until the punching block 4 contacts the guardrail plate, and punches the guardrail plate with the cooperation of the through hole 5, and the punched waste falls into the through hole 5.

[0029] Then the electric push rod 3 moves in the reverse direction, driving the rectangular frame 2 to return to its original position. At the same time, the motor 6 operates, driving the rotating disk 7 and the grinding disk 8 to rotate. Therefore, while the grinding disk 8 rotates, it moves upward, and the grinding disk 8 gradually inserts into the through hole 5, contacts the barbs on the bottom surface of the guardrail plate and grinds them until the grinding disk 8 returns to its initial position.

[0030] In a further preferred embodiment of the present utility model, as Figure 3 shown, when the stamping block 4 contacts the guardrail plate, the top surface of the grinding disk 8 is located below the bottom surface of the placing table 1.

[0031] In this embodiment, since there is a gap between the grinding disk 8 and the bottom surface of the placing table 1, the grinding disk 8 no longer shields the through hole 5, and the waste falling into the through hole 5 will directly drain out of the through hole 5, and there is no need for the staff to manually take out the waste.

[0032] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, a top groove 10 is formed at the top of the grinding disk 8, a spring 11 is fixedly connected to the inner bottom wall of the top groove 10, the top end of the spring 11 is fixedly connected with an arc-shaped protrusion 12. When the spring 11 is in a natural state, the arc-shaped protrusion 12 is completely located within the top groove 10, and a transmission part 13 is arranged below the arc-shaped protrusion 12.

[0033] In this embodiment, in the initial state, the spring 11 is in a natural state, and the arc-shaped protrusion 12 is completely located within the groove, so the arc-shaped protrusion 12 will not hinder the placement of the guardrail plate on the placing table 1.

[0034] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, the transmission part 13 includes a cavity 131 formed in the rotating disk 7, the bottom end of the arc-shaped protrusion 12 is fixedly connected with a vertical rod 132, the vertical rod 132 slides through the inner bottom wall of the top groove 10 and extends into the cavity 131. The bottom end of the vertical rod 132 is fixedly connected with two transmission rods 133, the transmission rods 133 are L-shaped, and the vertical sections of the transmission rods 133 slide through the inner bottom wall of the cavity 131 and extend below the rotating disk 7. A bottom frame 134 is fixedly connected to the bottom of the placing table 1 corresponding to the through hole 5, the bottom frame 134 is in a U-shaped configuration, and the bottom ends of the transmission rods 133 are located directly above the bottom frame 134.

[0035] In this embodiment, when the grinding disc 8 moves downward, the transmission rod 133 is driven to move downward synchronously. During the movement, the transmission rod 133 contacts the base frame 134 and squeezes the base frame 134. At the same time, the grinding disc 8 continues to move downward, so the spring 11 is stretched, and the arc-shaped protrusion 12 exposes the top groove 10. Therefore, after the waste falling from the through hole 5 falls to the top of the grinding disc 8, it will tilt and slide under the support of the arc-shaped protrusion 12, thereby preventing the waste from remaining on the top of the grinding disc 8.

[0036] When the guardrail plate is punched, the electric push rod 3 moves in the reverse direction, the grinding disc 8 moves upward, the transmission rod 133 leaves the base frame 134, and under the action of the restoring force of the spring 11, the arc-shaped protrusion 12 retracts into the top groove 10 to avoid the arc-shaped protrusion 12 from contacting the guardrail plate. Instead, the top surface of the grinding disc 8 contacts the barbs on the bottom surface of the guardrail plate to ensure the grinding effect of the guardrail plate.

[0037] In a further preferred embodiment of the present invention, Figure 1 As shown, the positioning portion 9 includes two sliding grooves 14 opened on the top of the placing table 1, and a screw 15 is connected to the corresponding two sliding grooves 14 for common rotation. One end of the screw 15 extends to the outside of the placing table 1, and the outer peripheral surface of the screw 15 is threadedly connected to two fixing plates 16. The fixing plate 16 is L-shaped, and the vertical section of the fixing plate 16 is slidably connected to the corresponding sliding groove 14.

[0038] In this embodiment, the outer circumference of the lead screw 15 is provided with two sections of threads with opposite rotation directions, and the two fixing plates 16 are respectively threadedly connected to the two sections of threads on the outer circumference of the lead screw 15, so that the rotation of the lead screw 15 drives the two fixing plates 16 to move in opposite directions. After placing the guardrail board on the placement table 1, the staff rotates the lead screw 15 to drive the two fixing plates 16 to move towards each other and approach the guardrail board, and the vertical section of the fixing plate 16 contacts the two side walls of the guardrail board in the length direction, and the bottom surface of the horizontal section of the fixing plate 16 contacts the top surface of the guardrail board, thereby positioning and fixing the guardrail board in the height direction and the length direction.

[0039] In a further preferred embodiment of the present invention, Figure 1 As shown, a positioning plate 17 is fixedly connected to the top of the placement platform 1, and one side of the guardrail plate is in contact with the positioning plate 17.

[0040] In this embodiment, when placing the guardrail board, one side surface of the guardrail board in the width direction is fitted with the positioning plate 17, so as to position the guardrail board in the width direction of the guardrail board.

[0041] The implementation principle of the above embodiment is:

[0042] In the initial state (such as Figure 1 and Figure 2As shown), the stamping block 4 is located above the placement table 1, the grinding disc 8 is located in the through hole 5, and the outer peripheral surface of the grinding disc 8 is in contact with the inner wall of the through hole 5, and the top surface of the grinding disc 8 is coplanar with the top surface of the placement table 1.

[0043] Place the guardrail board on the placement table 1, fit one side of the guardrail board in the width direction with the positioning plate 17, then rotate the screw 15 to drive the two fixing plates 16 to move towards each other and approach the guardrail board, and push the guardrail board to the center position of the placement table 1 until the corresponding two fixing plates 16 are in contact with the side of the guardrail board, thereby completing the positioning and fixation of the guardrail board.

[0044] Then the electric push rod 3 is started to drive the rectangular frame 2 to move downward, the rectangular frame 2 drives the punching block 4, the motor 6, the rotating disk 7 and the grinding disk 8 to move downward, the grinding disk 8 drives the transmission rod 133 to move downward, the transmission rod 133 contacts the bottom frame 134 during the movement, and squeezes the bottom frame 134, the spring 11 is stretched, and the arc-shaped protrusion 12 exposes the top groove 10. The punching block 4 moves downward to contact the guardrail plate to punch the guardrail plate, and the waste falls into the through hole 5 and is discharged through the through hole 5 (such as Figure 3 and Figure 4 shown).

[0045] Then the electric push rod 3 moves in the reverse direction, driving the rectangular frame 2 to return to the initial position, and the arc-shaped protrusion 12 retracts into the top groove 10 under the restoring force of the spring 11. The motor 6 drives the grinding disc 8 to rotate, and the grinding disc 8 rotates and inserts into the through hole 5 and contacts the barbs at the bottom of the guardrail plate, thereby grinding the guardrail plate.

[0046] Finally, the screw 15 is reversed to release the fixing of the guardrail plate and remove the guardrail plate.

[0047] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
