Description

Technical Field

[0001] This utility model belongs to the field of pipe clamp processing technology, and is particularly related to a tooling for tapping pipe clamps. Background Technology

[0002] The pipe clamp consists of two semi-circular pipe clamp rings, each with a bent section at both ends. Each bent section has a tapped connecting hole. Bolts are installed in these connecting holes, and nuts are used to secure the two rings, thus fixing the pipe fitting within the two clamp rings. Currently, the pipe clamp rings are tapped using a clamping device. A tapping device is placed above the clamping device to tap the connecting holes. After tapping, the clamping device is released, the ring is removed, and the process is repeated for subsequent tapping. This method requires repeatedly clamping and aligning the pipe clamp rings, resulting in low processing efficiency and warrants improvement. Utility Model Content

[0003] To address the aforementioned deficiencies in the prior art, this application provides a tooling for tapping pipe clamps, which can simultaneously restrict the up-and-down movement of multiple pipe clamp half-rings. Pushing the pipe clamp half-rings can complete alignment and material feeding, thereby improving processing efficiency.

[0004] To achieve the above objectives, the present invention employs the following technology: A tooling for tapping pipe clamps, comprising: A strip support platform has a pair of through holes along its width at the top. A guide rod with a semi-circular cross-section is provided along the length at the top of the strip support platform. The inner side of the guide rod faces the top of the support platform. The outer diameter of the guide rod matches the inner diameter of the pipe clamp half ring to be tapped. The guide rod is located between the pair of through holes. When the pipe clamp half ring is placed on the guide rod and is directly above the pair of through holes, the two connecting holes of the pipe clamp half ring are aligned with the pair of through holes. The limiting rod is positioned at intervals directly above the guide rod, and the distance between the limiting rod and the guide rod matches the thickness of the pipe clamp half-ring to be tapped.

[0005] Furthermore, the limiting rod is fixed to the top of the strip support platform by a pair of fixing brackets.

[0006] Furthermore, each fixing frame includes a pair of screws and a horizontal plate. The pair of screws are vertically fixed to the top of the strip support platform. A first nut and a second nut are threadedly connected to the screws from bottom to top. The horizontal plate is slidably connected to the screws in the vertical direction and is located between the first nut and the second nut. A limiting rod is fixedly connected to the bottom of the horizontal plate.

[0007] Furthermore, a strip-shaped through groove is provided on the top of the strip support platform along its length, and a fixed rod is connected to the bottom of the guide rod. Both ends of the guide rod protrude from both ends of the fixed rod, and the fixed rod is located in the strip-shaped through groove, with the length of the fixed rod matching the length of the strip-shaped through groove.

[0008] Furthermore, a notch is provided at one end of the top of the strip support platform, and an alignment hole is provided downwards at the top of the guide rod, with the alignment hole covering the upward-facing area of ​​the notch. A cylinder is vertically mounted at the top of the guide rod, and an alignment block is connected to the telescopic end of the cylinder. When the telescopic end of the cylinder is fully retracted, the alignment block is below the guide rod. When the telescopic end of the cylinder is fully extended, the alignment block protrudes through the top of the alignment hole. When multiple pipe clamp semi-rings are placed end-to-end on the guide rod, and the outermost pipe clamp semi-ring near the notch abuts against the alignment block protruding through the alignment hole, the two connecting holes of one of the pipe clamp semi-rings are aligned with a pair of through holes. The horizontal distance between the end of the guide rod near the notch and the inner side of the alignment block is less than the width of the pipe semi-ring.

[0009] The beneficial effects of this utility model are as follows: 1. It can simultaneously restrict the up and down movement of multiple pipe clamp half rings. Pushing the pipe clamp half rings can complete the alignment and feeding, which can improve processing efficiency; 2. Pushing the foremost pipe clamp half-ring to abut against the alignment block at the top of the alignment hole will align the middle pipe clamp half-ring with a pair of through holes, improving alignment efficiency. After the pipe clamp half-ring has finished tapping, control the retraction end of the cylinder to retract, and then continue to push all the pipe clamp half-rings forward. At the same time, control the retraction end of the cylinder to extend, which can push the foremost pipe clamp half-ring upward to disengage it from the guide rod, and then complete the unloading. It can also continue to block the subsequent pipe clamp half-rings. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0017] This application provides a tooling for tapping pipe clamps, such as... Figures 1-5 As shown, it includes a strip support platform 1, a guide rod 2, a limiting rod 3, etc.

[0018] Specifically, the top of the strip support platform 1 has a pair of through holes 101 along the width direction. The guide rod 2 has a semi-circular cross section and is fixed to the top of the support platform along the length direction of the strip support platform 1. The inner side of the guide rod 2 faces the top of the support platform. The outer diameter of the guide rod 2 matches the inner diameter of the pipe clamp half ring 7 to be tapped. The guide rod 2 is located between the pair of through holes 101. When the pipe clamp half ring 7 is placed on the guide rod 2 and is directly above the pair of through holes 101, the two connecting holes 701 of the pipe clamp half ring 7 are aligned with the pair of through holes 101. The limiting rod 3 is spaced directly above the guide rod 2. The distance between the limiting rod 3 and the guide rod 2 matches the thickness of the pipe clamp half ring 7 to be tapped.

[0019] In actual use, a tapping device is set above the strip support platform 1. The two drill bits of the tapping device are aligned with a pair of through holes 101 on the strip support platform 1. Then, multiple pipe clamp half rings 7 are pushed into the guide rod 2 from one end. The limiting rod 3 above the guide rod 2 will prevent the pipe clamp half rings 7 from moving upward. Therefore, the pipe clamp half rings 7 pushed into the guide rod 2 will be connected end to end without overlapping. When the pair of connecting holes 701 of the foremost pipe clamp half ring 7 are aligned with a pair of through holes 101 on the strip support platform 1, the tapping device is controlled to tap the pipe clamp half ring 7. After tapping is completed, the drill bit of the tapping device is withdrawn. Then, the pipe clamp half ring 7 is pushed forward so that the connecting hole 701 of the next pipe clamp half ring 7 is aligned with the through hole 101. Repeating the above steps can complete the tapping of multiple pipe clamp half rings 7. Throughout the process, there is no need to control the clamping equipment to clamp the pipe clamp half ring 7. After the pipe clamp half ring 7 is pushed, it will automatically fall from the other end of the guide rod 2 to realize the unloading, which can effectively improve the processing efficiency.

[0020] For details, please refer to Figure 1 , Figure 2The limiting rod 3 is fixed to the top of the strip support platform 1 by a pair of fixing brackets 4. More specifically, each fixing bracket 4 includes a pair of screws 402 and a horizontal plate 401. The pair of screws 402 are vertically fixed to the top of the strip support platform 1. A first nut 403 and a second nut 404 are threadedly connected to the screws 402 from bottom to top. The horizontal plate 401 is slidably connected to the screws 402 in the vertical direction and is located between the first nut 403 and the second nut 404. The limiting rod 3 is fixedly connected to the bottom of the horizontal plate 401. The height of the horizontal plate 401 can be adjusted by adjusting the height of the first nut 403 and the second nut 404, thereby adjusting the distance between the limiting rod 3 and the guide rod 2 to accommodate the placement of pipe clamp half rings 7 of various thicknesses on the guide rod 2.

[0021] For details, please refer to Figure 3 The strip support platform 1 has a strip-shaped through groove 102 along its length at the top. A fixing rod 5 is connected to the bottom of the guide rod 2. The guide rod 2 and the fixing rod 5 can be integrated into one structure. Both ends of the guide rod 2 protrude beyond the ends of the fixing rod 5. The fixing rod 5 is located within the strip-shaped through groove 102, and its length matches the length of the strip-shaped through groove 102. This design facilitates the installation of the guide rod 2 onto the strip support platform 1; the fixing rod 5 can be directly inserted into the strip-shaped through groove 102.

[0022] Preferred options, please refer to Figure 2 , Figure 3 , Figure 5A notch 103 is provided at one end of the top of the strip support platform 1. An alignment hole 201 is provided downward at the top of the guide rod 2, and the alignment hole 201 is within the upward coverage area of ​​the notch 103. A cylinder 6 is vertically provided at the top of the guide rod 2. An alignment block 601 is connected to the telescopic end of the cylinder 6. When the telescopic end of the cylinder 6 is fully retracted, the alignment block 601 is below the guide rod 2. When the telescopic end of the cylinder 6 is fully extended, the alignment block 601 protrudes from the top of the alignment hole 201. When multiple pipe clamp half-rings 7 are placed on the guide rod 2 with their ends connected, the pipe clamp half-ring 7 closest to the outermost end of the notch 103 abuts against the alignment block protruding from the top of the alignment hole 201. When block 601 is in place, the two connecting holes 701 of one of the pipe clamp half-rings 7 are aligned with a pair of through holes 101. With this setting, pushing the foremost pipe clamp half-ring 7 to abut against the alignment block 601 that protrudes from the top of the alignment hole 201 can align the middle pipe clamp half-ring 7 with the pair of through holes 101, improving alignment efficiency. After the pipe clamp half-ring 7 has finished tapping, the telescopic end of the control cylinder 6 is retracted, and then all the pipe clamp half-rings 7 are pushed forward. At the same time, the telescopic end of the control cylinder 6 is pushed out, which can push the foremost pipe clamp half-ring 7 upward, so that it is separated from the guide rod 2, and then the material is unloaded. It can also continue to block the subsequent pipe clamp half-rings 7. In actual use, several pipe clamp half-rings 7 that have already been tapped can be placed at the front end of the guide rod first, so that when the foremost pipe clamp half-ring 7 abuts against the alignment block 601, the through hole 101 of the pipe clamp half-ring 7 that is closest to the alignment block 601 is aligned with the through hole 101.

[0023] Specifically, the horizontal distance between the end of the guide rod 2 near the notch 103 and the inner side of the alignment block 601 is less than the width of the pipe half-ring. The width of the pipe clamp half-ring 7 refers to the length of the pipe clamp along its axial direction. This arrangement makes it easier for the pipe clamp half-ring 7 to slide downwards and detach from the guide rod 2 after being pushed up by the alignment block 601.

[0024] The above are only some of the embodiments listed in this application and are not intended to limit this application.
