DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0022] See also Figure 1-Figure 4 The present application provides a punching machine fixture for producing square pile end plates, including a workbench 10 and a side clamping assembly 20.

[0023] See also Figure 1 , workbench 10; wherein, a stamping groove is provided in the middle position of the workbench 10 to facilitate the falling of the end plate after stamping.

[0024] See also Figure 1 , Figure 2 , Figure 3 and Figure 4The side clamping assembly 20 includes a driving member 210, a clamping plate 220, a sliding connection block 230 and a telescopic connection rod 240. The driving member 210 is installed on one side of the workbench 10. The two clamping plates 220 are respectively screwed at the two ends of the rotating end of the driving member 210, and the driving member 210 drives the two clamping plates 220 to move away from and close to each other. The two sliding connection blocks 230 are respectively slidably arranged at one end of the two clamping plates 220 close to the driving member 210. The two ends of the telescopic connection rod 240 are respectively connected to the opposite surfaces of the two sliding connection blocks 230. The sliding connection blocks 230 and the clamping plates 220 are commonly provided with adjusting bolts 250. When the end plate needs to be clamped, the end plate is first placed on the upper surface of the workbench 10, and then the driving member 210 is started so that the two clamping plates 220 are close to each other to clamp the two sides of the end plate, and then the adjusting bolt 250 is loosened, and the two sliding connection blocks 230 are slid respectively so that the telescopic connecting rod 240 can be pressed against the rear end of the end plate, just so that the position of the end plate to be punched is located directly below the punch, and then the adjusting bolt 250 is tightened to fix the telescopic connecting rod 240 to achieve the positioning of the end plate, and then the punching can be performed. When punching the end plates of the same specifications, the position of the telescopic connecting rod 240 can be adjusted first. When punching the end plates of other specifications, the position of the telescopic connecting rod 240 is pre-adjusted, and then the rear end of the end plate is pressed against the rear side of the end plate to achieve the positioning of the end plate. By setting the sliding connection block 230, the telescopic connection rod 240 and the adjusting bolt 250, different end plates can be positioned so that when stamping end plates of different specifications, the end plates can be limited without deviation in the placement position, thereby improving the stamping accuracy.

[0025] In this embodiment, the driving member 210 includes a motor 211 and a threaded rod 212. The motor 211 is installed on one side of the workbench 10. One end of the threaded rod 212 is fixedly connected to the output end of the motor 211. Two clamping plates 220 are respectively screwed to the two ends of the threaded rod 212. The motor 211 drives the two clamping plates 220 to move away from and close to each other on the threaded rod 212. Specifically, a bearing seat 270 is provided at one end of the threaded rod 212 that is away from the motor 211, and the bearing seat 270 is fixedly connected to the workbench 10. The two ends of the threaded rod 212 are respectively provided with a first thread 2121 and a second thread 2122 with opposite threads. When the end plate needs to be clamped, the motor 211 is started to rotate the threaded rod 212. Under the action of the first thread 2121 and the second thread 2122, the two clamping plates 220 move closer to each other to achieve clamping of both sides of the end plate.

[0026] In the specific setting, the bottom of the two clamping plates 220 is slidably connected to the upper surface of the workbench 10. The sliding connection between the clamping plates 220 and the workbench 10 makes the two clamping plates 220 more stable when approaching or moving away from each other, and more stable when clamping the end plate.

[0027] Furthermore, the bottom of the two clamping plates 220 is fixedly connected with a first slider 260, and the two sides of the workbench 10 are respectively provided with a first slide groove 110 matched with the two first sliders 260. The first slider 260 slides inside the first slide groove 110 to achieve the sliding connection between the clamping plates 220 and the workbench 10.

[0028] In this embodiment, two sliding connection blocks 230 are respectively provided with through slots 231 at the bottom, and the two sliding connection blocks 230 are respectively slidably arranged on both sides of the top of the two clamping plates 220 through the through slots 231. Specifically, second sliders 280 are arranged on opposite surfaces of the bottom ends of the through slots 231, and second slide slots 221 cooperating with the second sliders 280 are respectively provided on both sides of the clamping plates 220. The sliding connection blocks 230 are clamped on the top of the clamping plates 220 to achieve sliding connection between the sliding connection blocks 230 and the clamping plates 220.

[0029] See also Figure 1 The punching machine fixture for producing the square pile end plate also includes a top positioning assembly 30, which is installed on the upper surface of one end of the workbench 10 and presses the end plate. The top positioning assembly 30 can further position and clamp the end plate, thereby improving the stability of the end plate during punching.

[0030] In this embodiment, the top positioning assembly 30 includes a mounting seat 310, a cylinder 320, a rotating rod 330 and a pressing block 340. The mounting seat 310 is fixed to the upper surface of one end of the workbench 10, the cylinder 320 is mounted on the mounting seat 310, the top and the bottom of one end of the rotating rod 330 are respectively hinged at the cylinder rod end of the cylinder 320 and the mounting seat 310, and the pressing block 340 and the other end of the rotating rod 330 are pressed against the upper surface of the end plate. When it is necessary to press against the upper surface of the end plate, the cylinder 320 is started to retract the cylinder rod end of the cylinder 320, so that the rotating rod 330 rotates downward to realize that the pressing block 340 presses against the upper surface of the end plate. When it is released, the cylinder 320 is started again to lift the rotating rod 330 upward to realize that the pressing block 340 is lifted upward.

[0031] Working principle of the punch fixture for square pile end plate production:

[0032] When the end plate needs to be clamped, first place the end plate on the upper surface of the workbench 10, then start the driving member 210, so that the two clamping plates 220 are close to each other to clamp the two sides of the end plate, then loosen the adjusting bolt 250, slide the two sliding connection blocks 230 respectively so that the telescopic connecting rod 240 can be tightly against the rear end of the end plate, just so that the position of the end plate to be punched is located directly below the punch, then tighten the adjusting bolt 250 to fix the telescopic connecting rod 240 to achieve the positioning of the end plate, and then punch. When punching end plates of the same specifications, first adjust the position of the telescopic connecting rod 240. When punching end plates of other specifications, pre-adjust the position of the telescopic connecting rod 240, and then make the rear end of the end plate tightly against the rear side of the end plate to achieve the positioning of the end plate. By setting the sliding connection block 230, the telescopic connection rod 240 and the adjusting bolt 250, different end plates can be positioned so that when stamping end plates of different specifications, the end plates can be limited without deviation in the placement position, thereby improving the stamping accuracy.
