[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] It should be noted that all directional indicators (such as up, down, left, right, front, back, upper end, lower end, top, bottom, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0029] See Figure 1 and Figure 6 As shown (label A in the figure represents PVC pipe), a drilling device for the outer wall of PVC pipe includes an operating table 1. The operating table 1 is provided with a clamping mechanism 2 for placing PVC pipe and clamping and fixing the PVC pipe at the drilling point, a drilling mechanism 3 for drilling the PVC pipe, and a traction mechanism 4 for pulling the PVC pipe. The drilling mechanism 3 spans above the clamping mechanism 2, and the traction mechanism 4 is located downstream of the clamping mechanism 2.

[0030] Further, see Figure 2 As shown, the clamping mechanism 2 includes a support frame 21, which is fixed to the table surface of the operating table 1. A receiving block 22 is provided on the support frame 21, and a receiving groove 221 is formed on the receiving block 22. The receiving groove 221 is a V-shaped groove, which is used to place the PVC pipe. A clamping assembly 23 is provided on the support frame 21 downstream of the receiving block 22. (See attached image) Figure 2-3 As shown, the clamping assembly 23 includes a pair of symmetrically arranged double-rod cylinders 231. The double-rod cylinders 231 are fixed on the support frame 21 by corresponding support seats. Each output front end of the double-rod cylinders 231 is provided with a clamping block 232. The clamping block 232 has a clamping groove 2321, which is a V-shaped groove with anti-slip texture. During installation, the double-rod cylinders 231 are fixed on the support frame 21 by corresponding support seats. During operation, the pair of clamping blocks 232 are driven by the corresponding double-rod cylinders 231 to move closer and further apart, thereby clamping and fixing the PVC pipe.

[0031] In this embodiment, after the pair of clamping blocks 232 clamp and fix the PVC pipe, the drilling mechanism 3 drills a hole in the outer wall of the PVC pipe at the upper middle position of the pair of clamping blocks 232. Therefore, in order to avoid damage to the pair of clamping blocks 232 by the drilling mechanism 3, a relief groove 2322 is provided in the pair of clamping blocks 232.

[0032] Further, see Figure 4As shown, the drilling mechanism 3 includes a fixed frame 31, on which a rotating shaft assembly 32 and a lifting cylinder 33 are mounted. The rotating shaft assembly 32 is mounted on the fixed frame 31 via a pair of guide shafts 34, while the lifting cylinder 33 is fixed to the top of the fixed frame 31. The piston rod of the lifting cylinder 33 is connected to the rotating shaft assembly 32, and the rotating shaft assembly 32 can be driven to move up and down along the guide shafts 34 by the lifting cylinder 33, thereby performing drilling operations on the PVC pipe. The number of sets of guide shafts 34 is only one embodiment and is not intended to limit the scope of this application. In actual installation, more sets can be used as long as the requirements are met.

[0033] In this embodiment, see Figure 5-6 As shown, the rotating shaft assembly 32 includes a pair of vertically distributed movable plates 321. The front end of the piston rod of the lifting cylinder 33 is connected to the upper end face of the movable plate 321 located on the top. A motor 322 is provided on the lower end face of the upper movable plate 321. The output shaft of the motor 322 is connected to a connecting shaft 324 through a coupling 323. The connecting shaft 324 passes through the lower movable plate 321 through a bearing 325 and is connected to a chuck 326 for clamping a drill bit 327 after passing through, thereby realizing the rotation of the drill bit 327 by the motor 322, and thus realizing the drilling operation.

[0034] Further, see Figure 7 As shown, the traction mechanism 4 includes a lead screw slide linear guide rail 41 and a clamping assembly 42. The clamping assembly 42 is disposed on the lead screw slide linear guide rail 41, and the clamping assembly 42 can move back and forth on the lead screw slide linear guide rail 41 by being driven by the lead screw slide linear guide rail 41. In this embodiment, in order to limit the maximum forward and backward movement of the clamping assembly 42 on the lead screw slide linear guide rail 41, the traction mechanism 4 also includes a limiting mechanism. The limiting mechanism includes a pair of U-shaped photoelectric sensors 43 and a sensing plate 44. During installation, the pair of U-shaped photoelectric sensors 43 are fixed on the table surface of the operating table 1 by corresponding support seats and are respectively disposed at the front and rear ends of the lead screw slide linear guide rail 41. The sensing plate 44 is fixed on the slide of the lead screw slide linear guide rail 41.

[0035] And continue to see Figure 7As shown, the clamping assembly 42 includes a rotary cylinder 421, which is fixed on the linear guide rail 41 of the lead screw slide via a corresponding support seat. A gripper cylinder 422 is mounted on the rotation axis of the rotary cylinder 421 via a connecting plate 423. The gripper cylinder 422 is a three-jaw cylinder, but it is not limited to three-jaw cylinders; a four-jaw cylinder can also be used, depending on the need. During operation, the gripper cylinder 422 moves outward to tighten the inner wall of the PVC pipe, thereby clamping the PVC pipe.

[0036] The working principle of this utility model is as follows:

[0037] During drilling operations, the linear guide rail 41 of the lead screw slide first drives the clamping assembly 42 to move to the front end of the linear guide rail 41 of the lead screw slide (i.e., Figure 1 The initial position of the linear guide rail 41 (left end) is the zero point; then the PVC pipe to be drilled is placed in the receiving groove 221 of the receiving block 22 of the clamping mechanism 2, at which time the PVC pipe is initially positioned in the V-groove; then the PVC pipe is pushed downstream (i.e., in the direction of the traction mechanism 4) so ​​that the front end of the PVC pipe abuts against the end face of the connecting plate 423. At this time, the gripper cylinder 422 is housed in the inner hole of the PVC pipe; then the gripper cylinder 422 is activated, so that the gripper of the gripper cylinder 422 moves outward and supports and fixes the inner wall of the inner hole of the PVC pipe; then the linear guide rail 41 of the screw slide moves backward by driving the clamping assembly 42, thereby pulling the PVC pipe to move, so that the first drilling position moves directly below the drill bit 327; then a pair of double rod cylinders 231 drive the corresponding clamping blocks 232 to move closer together, clamp and fix the PVC pipe, and the drilling mechanism 3 starts to drill the PVC pipe.

[0038] After completing the drilling operation at the first hole location, see Figure 8 As shown, a pair of double-rod cylinders 231 drive the corresponding clamping blocks 232 away, releasing the clamping and fixing of the PVC pipe. Under the coordinated drive of the linear guide rail 41 of the screw slide table and the rotary cylinder 421 (driving the PVC pipe to move and rotate), the PVC pipe is pulled to the next hole position until all drilling operations are completed.

[0039] Finally, it should be noted that, as described above, the drilling operation of this device on PVC pipes is performed from one end of the PVC pipe to the other; therefore, after the initial installation of the PVC pipe is completed, it is necessary to ensure that the first drilling position is directly below or upstream of the drill bit 327.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
