In the existing drilling operations, there are the following two problems: ① Before drilling, the staff uses a clamping device to fix the tubular part, and then uses a ruler and a paintbrush to mark the points to be drilled on the side wall of the tubular part, which is not only inefficient, but also the marked points are inaccurate; ② The clamping device only plays the role of fixing the tubular part and has no auxiliary effect on the drilling operation. Therefore, this solution provides a clamping device for tubular parts facilitating drilling to solve the above problems. Content of the Utility Model

[0003] To solve the deficiencies of the existing technology, the utility model provides a clamping device for tubular parts facilitating drilling, which can automatically mark the points to be drilled, improving the efficiency and accuracy.

[0004] In order to achieve the purpose of the utility model, the following scheme is proposed:

[0018] As Figure 1 shown, this embodiment provides a clamping device for tubular parts facilitating drilling, including an arc-shaped support plate 1, a first clamping mechanism 2, and a second clamping mechanism 3.

[0019] Specifically, the arc-shaped support plate 1 is fixedly arranged on the top of the base 11. The base 11 is arranged on the bracket 12. The arc-shaped support plate 1 is used to place the tubular parts to be drilled. An operating table 4 is arranged below the base 11. The first clamping mechanism 2 and the second clamping mechanism 3 are both arranged on the operating table 4 and are located on both sides of the arc-shaped support plate 1. The first clamping mechanism 2 and the second clamping mechanism 3 are used to clamp the tubular parts.

[0020] The specific implementation manner of the first clamping mechanism 2 is as follows: As Figures 1-4 shown, the first clamping mechanism 2 includes a first telescopic cylinder 21, a push plate 22, five first clamping plates 23 distributed in an array, and five bases 24 distributed in an array. One first clamping plate 23 corresponds to one base 24. A sliding plate 232 is fixedly arranged on the outer wall of the first clamping plate 23. The bottom of the sliding plate 232 is horizontally slidably matched with the corresponding base 24. A return spring 241 is arranged in the base 24. The return spring 241 is connected to the sliding plate 232. The return spring 241 is used to reset the sliding plate 232 and the first clamping plate 23. The first clamping plate 23 is arranged in an arc shape. The size of the first clamping plate 23 matches that of the tubular part. A semi-circular notch 231 is arranged at the top of the first clamping plate 23. The first telescopic cylinder 21 can be a pneumatic cylinder, an oil cylinder or a hydraulic cylinder. The first telescopic cylinder 21 is connected to the push plate 22. The push plate 22 acts on all the sliding plates 232 and is used to make all the first clamping plates 23 slide towards the tubular part. When the first clamping plate 23 clamps the tubular part, the semi-circular notch 231 is used to mark the point to be drilled.

[0021] In order to improve the stability of the sliding plate 232 during the sliding process, as Figure 4 、 Figure 5 shown, in this embodiment, a T-shaped groove 242 is arranged at the top of the base 24. A guide rod 243 is arranged in the T-shaped groove 242. The bottom of the sliding plate 232 is slidably matched with the guide rod 243. The return spring 241 is arranged on the outer periphery of the guide rod 243. The return spring 241 is connected to the sliding plate 232.

[0022] As for the structure of the second clamping mechanism 3, it can be set to be the same as or different from the structure of the first clamping mechanism 2. Since the semi-circular notch 231 of the first clamping plate 23 has already played the role of marking the point to be drilled, in this embodiment, the structure of the second clamping mechanism 3 is different from that of the first clamping mechanism 2. The second clamping mechanism 3 only needs to realize the function of clamping and fixing the tubular part. Specifically, as Figure 1 、 Figure 2 shown, the second clamping mechanism 3 includes a second telescopic cylinder 31, a straight plate 32, and two second clamping plates 33 fixedly arranged on the straight plate 32. The second telescopic cylinder 31 is arranged on the second support plate. The second telescopic cylinder 31 can be a pneumatic cylinder, an oil cylinder or a hydraulic cylinder. Its movable end is connected to the straight plate 32. The second clamping plate 33 is used to clamp the tubular part.

[0023] In the above solution, all the bases 24 can be fixedly arranged on the top of the operating table 4, which means that the distance between two adjacent first clamping plates 23 is non-adjustable. In order to meet different requirements, the hole spacing on the side wall of the tubular part needs to be adjusted accordingly. Therefore, as a preferred solution, the clamping device further includes a spacing adjustment mechanism 5 for adjusting the distance between two adjacent first clamping plates 23. The specific implementation method is as follows:

[0024] As shown in Figure 1 , Figure 2 , Figure 6 , the spacing adjustment mechanism 5 includes a third telescopic rod 51, a regulation plate 52 and a rectangular plate 53. The first telescopic cylinder 21 is arranged on the first support plate. The third telescopic rod 51 is parallel to the direction of the first telescopic cylinder 21. The regulation plate 52 is closely attached to the top surface of the operating table 4 and is located below the first support plate. An installation groove 41 is provided at the top of the operating table 4. The third telescopic rod 51 is arranged in the installation groove 41. The third telescopic rod 51 can be a pneumatic cylinder, an oil cylinder or a hydraulic cylinder, and its movable end is connected to the regulation plate 52. There is a certain gap between the base 11 and the operating table 4, and the size of this gap allows the regulation plate 52 to pass through. The regulation plate 52 is provided with five sliding grooves 521. The distance between any two adjacent sliding grooves 521 is equal, and the distance between one end of two adjacent sliding grooves 521 is greater than that of the other end. The end of the rectangular plate 53 is arranged on the support block, and the support block is arranged on the top of the operating table 4. A square block 245 is provided at the bottom of the base 24, and all the square blocks 245 are slidably matched with the rectangular plate 53. A cylinder 244 is provided at the bottom of the square block 245, and the cylinder 244 is slidably matched in the corresponding sliding groove 521.

[0025] The usage method is as follows:

[0026] S1. First, use the third telescopic rod 51 to move the regulation plate 52. Since the base 24 can only slide along the rectangular plate 53, when the regulation plate 52 moves, it will cause the cylinder 244, the square block 245 and the base 24 as a whole to slide along the rectangular plate 53, so as to adjust the distance between two adjacent first clamping plates 23 to the preset position.

[0027] S2. Place the tubular part to be drilled on the arc-shaped supporting plate 1.

[0028] S3. On the one hand, use the second telescopic cylinder 31 to move the straight plate 32 until the second clamping plate 33 clamps the tubular part; at the same time, use the first telescopic cylinder 21 to move the push plate 22. The push plate 22 acts on all the sliding plates 232, so that all the first clamping plates 23 slide towards the tubular part until all the first clamping plates 23 clamp the tubular part. At this time, the position of the semi-circular notch 231 is the point to be drilled.

[0029] S4. Drill the hole.

[0030] S5. After the drilling is completed, both the second telescopic cylinder 31 and the first telescopic cylinder 21 return to their original positions, and all the first clamping plates 23 return to their original positions under the action of the return spring 241.

[0031] The above embodiments are only used to illustrate the technical idea and characteristics of the present invention, and do not represent the only or limit the present invention. Those skilled in the art should understand that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention all fall within the scope of protection of the present invention.
