After the pipe 100 to be processed is placed on the support platform 41, the first clamping plate 51 and the second clamping plate 61 are driven by the second driving component 7 to approach the pipe 100 respectively, and the pipe 100 is clamped in the horizontal direction by the first clamping plate 51 and the limiting column 42, and the pipe 100 is pressed on the support platform 41 in the vertical direction by the second clamping plate 61, so that the pipe 100 can be fixed on the pipe drilling jig.
[0025] Specifically, the operating steps of clamping the pipe 100 to be processed using the pipe drilling jig provided in this embodiment are as follows: placing the pipe 100 to be processed on the support platform 41, starting the second driving component 7 to drive the movable rod 5 to rotate so that the first clamping plate 51 approaches the pipe 100, and clamps the pipe 100 between the first clamping plate 51 and the limiting column 42, and at the same time, the second driving component 7 drives the pressing block 6 to rotate relative to the movable rod 5, so that the second clamping plate 61 approaches the pipe 100 and presses the pipe 100 on the support platform 41, so that the pipe 100 can be fixed on the movable plate 2 so that the position of the pipe 100 on the pipe drilling jig during the drilling process remains stable; when it is necessary to adjust the position of the hole to be drilled on the pipe 100, the first driving component 3 drives the movable plate 2 to move on the base 1 to adjust the position of the pipe 100, and there is no need to operate the clamping component during the adjustment process. The pipe drilling jig provided in this embodiment clamps the pipe 100 by contacting the surface of the pipe 100 with the first clamping plate 51 or the second clamping plate 61, which is beneficial to reducing the pressure per unit area on the surface of the pipe 100 to prevent the pipe 100 from deforming. The position adjustment operation of the pipe 100 is convenient, avoiding deformation of the pipe 100 due to pressure during the adjustment process, which is beneficial to improving product quality.
[0026] like Figure 1 and Figure 2 As shown, the base 1 is provided with a slide groove 11, the length direction of the slide groove 11 is consistent with the moving direction of the movable plate 2, and the movable plate 2 is provided with a protrusion that matches the slide groove 11. The slide groove 11 provided on the base 1 is used to guide the movable plate 2 to move on the base 1, and the movable plate 2 is kept on the base 1 through the cooperation between the protrusion and the slide groove 11, so as to prevent the movable plate 2 from deviating from the preset direction or detaching from the base 1 when moving, which is beneficial to improving the structural stability of the pipe drilling jig.
[0027] Please combine Figure 2 and Figure 4 In this embodiment, the first driving assembly 3 includes a motor 31 and a screw rod 32 disposed at the output end of the motor 31. The screw rod 32 is rotatably disposed on the base 1 and the axial direction of the screw rod 32 is consistent with the moving direction of the movable plate 2. The movable plate 2 is provided with a threaded hole matched with the screw rod 32. The motor 31 drives the screw rod 32 to rotate, so as to drive the movable plate 2 to move along the axial direction of the screw rod 32, and the stroke and direction of movement of the movable plate 2 can be adjusted by controlling the number of turns and the direction of rotation of the screw rod 32, so as to accurately adjust the position of the pipe 100 clamped on the pipe drilling jig and improve the processing accuracy.
[0028] like Figure 2 and Figure 3 As shown, the second driving assembly 7 includes a movable sleeve 71 mounted on the movable rod 5, a cylinder 72 rotatably connected to the support frame 4, and a telescopic rod 73 arranged at the output end of the cylinder 72, the end of the telescopic rod 73 away from the movable sleeve 71 is rotatably connected to the movable sleeve 71, and a rotatable connecting rod 74 is also provided on the movable sleeve 71, and the end of the connecting rod 74 away from the movable sleeve 71 is rotatably connected to the end of the pressing block 6 away from the support frame 4.

When the telescopic rod 73 moves, it pushes or pulls the movable rod 5 to rotate and drives the movable sleeve 71 to slide on the movable rod 5. When the movable rod 5 rotates, the first clamping plate 51 approaches or moves away from the pipe 100 placed on the support platform 41, and during the sliding process of the movable sleeve 71, it drives the connecting rod 74 to push or pull the pressure block 6 to rotate so that the second clamping plate 61 synchronously approaches or moves away from the pipe 100 placed on the support platform 41, thereby facilitating the operation of the jig for drilling holes in the pipe.
[0029] In detail, the movable rod 5 is sleeved with a spring 52, and the spring 52 abuts against the movable sleeve 71 and drives the movable sleeve 71 to move away from the pressing block 6. The elastic force provided by the spring 52 drives the movable sleeve 71 to move away from the pressing block 6, and the spring 52 is in a compressed state after the clamping assembly clamps the pipe 100. When the second driving assembly 7 is turned on to drive the movable rod 5 to rotate and release the lock on the pipe 100, the spring 52 restores its original length and pushes the movable sleeve 71 to slide on the movable rod 5 and away from the pressing block 6. At this time, the pressing block 6 rotates under the drive of the connecting rod 74 to make the second clamping plate 61 away from the pipe 100, so as to facilitate the removal of the processed pipe 100.

[0031] Specifically, a protruding mounting rod 75 is provided on the outer peripheral wall of the movable sleeve 71, and a connecting block 76 is provided at one end of the telescopic rod 73 away from the cylinder 72, and a first mounting hole matching with the mounting rod 75 is provided on the connecting block 76, and a second mounting hole matching with the mounting rod 75 is provided on the connecting rod 74.

[0032] Please refer to Figure 1 and Figure 3 , the first pressing plate 51 and the second pressing plate 61 are respectively provided with a buffer pad 53, and the buffer pad 53 covers the side of the first pressing plate 51 close to the support frame 4 and the side of the second pressing plate 61 close to the support frame 4. The buffer pad 53 is respectively provided on the first pressing plate 51 and the second pressing plate 61 to keep the side of the first pressing plate 51 in contact with the pipe 100 and the side of the second pressing plate 61 in contact with the pipe 100 soft, and the first pressing plate 51 and the second pressing plate 61 can be buffered by the buffer pad 53 when they are respectively in contact with the pipe 100, so as to avoid the first pressing plate 51 or the second pressing plate 61 from exerting too much pressure on the pipe 100, which may cause deformation of the pipe 100.
[0033] Please combine Figure 2 and Figure 4 In this embodiment, two clamping assemblies are provided on the movable plate 2 at intervals, and the two clamping assemblies are respectively provided near the opposite sides of the movable plate 2. By providing two spaced clamping assemblies on the movable plate 2 to respectively clamp the two ends of the pipe 100 to be processed, the stability of the pipe 100 on the pipe drilling jig is further improved, and the loosening of the pipe 100 during processing is prevented to affect the processing quality.
[0034] In detail, a collecting box 21 is further provided on the movable plate 2, and the collecting box 21 is located between the two clamping assemblies. The collecting box 21 is used to contain metal debris dropped during the drilling process on the pipe 100, so as to prevent the metal debris from being scattered into the surrounding environment, and to collect the metal debris in the collecting box 21 for subsequent recycling.
