[0020] Embodiment 1
[0021] Combined with the attached Figures 1-3 , this embodiment proposes a positioning and cutting tooling, including a fixed clamping plate 10. A first bracket 11 is fixedly arranged on one side of the fixed clamping plate 10. A slide bar 20 is fixedly arranged on the fixed clamping plate 10. A scale is arranged on the slide bar 20. A cutting clamping plate 12 is movably arranged on the slide bar 20. A second through hole 120 is arranged on the cutting clamping plate 12. A second bracket 14 is fixedly arranged on the side of the second through hole 120 facing the fixed clamping plate 10. The heights of the first bracket 11 and the second bracket 14 are the same; a cutting pliers 21 is arranged on the cutting clamping plate 12.
[0022] The positioning and cutting tooling of this embodiment has the following basic working principle: Insert the pipe to be cut into the second through hole 120 of the cutting clamping plate 12, so that the pipe is supported by the first bracket 11 and the second bracket 14. Then move the cutting clamping plate 12, accurately determine the cutting position according to the scale on the sliding rod 20, and then operate the cutting pliers 21 to cut the pipe.
[0023] In this embodiment, the first bracket 11 and the second bracket 14 work together to support the pipe to be cut. Among them, the second bracket 14 also serves as the bearing part for bearing the shearing force of the cutting pliers 21. The first bracket 11 and the second bracket 14 are of the same height, and the cutting pliers 21 are arranged on the cutting clamping plate 12. Therefore, it can be ensured that after the cutting pliers 21 cut, the cross-section cut of the pipe can be kept flat and vertical.
[0024] In short, the positioning and cutting tooling of this embodiment has a simple structure, low cost, is convenient for installation and disassembly, and is easy to carry, and is suitable for the cutting requirements of small batches of pipes. Through the mutual cooperation of the cutting clamping plate 12 and the sliding rod 20, the error existing in traditional manual measurement is eliminated, and the cutting length of the pipe is ensured to be accurate. It can be understood that the operator can directly determine the cutting position and the placement position of the pipe through the scale on the sliding rod 20, reducing the cutting time of the operator. That is, the positioning and cutting tooling of this embodiment improves the cutting efficiency and accuracy of the pipe. The cutting pliers 21 are arranged on the cutting clamping plate 12, and their relative positions are not easy to change, which also ensures the flatness of the cut and avoids secondary trimming.
[0025] In some embodiments, a first through hole 100 is provided on the fixed clamping plate 10 near the first bracket 11, and the center of the first through hole 100 is coaxial with the center of the second through hole 120. It can be understood that if the first through hole 100 is not provided, the cutting can only start from the end of the pipe. When the first through hole 100 is provided on the fixed clamping plate 10, the pipe can pass through the first through hole 100 and the second through hole 120 at the same time, that is, the pipe can be sheared at any position on the pipe.
[0026] In addition, in some embodiments, both the first bracket 11 and the second bracket 14 are arc-shaped structures with open upper parts, aiming to adapt to the shape of the pipe to prevent the pipe from rolling, thereby further improving the shearing effect on the pipe, and the open upper structure form is also convenient for placing the pipe.
[0027] It is understandable that the pipe fitting will inevitably roll or shift axially during placement on the positioning cutting tool. If the pipe fitting moves during the operation of the shearing pliers 21, the cutting quality will inevitably be affected. Therefore, in an improved embodiment, a mechanism for locking the pipe fitting is further provided on the fixed clamp 10. This mechanism includes a threaded rod 15. The fixed clamp 10 is provided with a screw hole, and the threaded rod 15 is configured to cooperate with the screw hole. A clamping block 16 is fixedly provided on the side of the threaded rod 15 facing the first bracket 11. The clamping block 16 is in the shape of a circular arc with one side open, and the opening of the clamping block 16 faces the first bracket 11. Thus, by rotating the threaded rod 15, the clamping block 16 can be moved closer to and away from the first bracket 11. When the clamping block 16 approaches the first bracket 11, the pipe fitting is locked and fixed. When the clamping block 16 moves away from the first bracket 11, the pipe fitting is unlocked. In this embodiment, by locking the pipe fitting, the pipe fitting is prevented from moving freely, thereby ensuring cutting quality.
[0028] Furthermore, a screwing head 17 can be fixedly provided at the end of the threaded rod 15 away from the clamping block 16. The screwing head 17 can increase the contact area between the hand or tool and the threaded rod 15, thereby improving the convenience of screwing and helping to ensure the locking quality, thereby ensuring the cutting quality.
[0029] The slide bar 20 in this embodiment is used as a sliding track for the cutting splint 12. The cutting splint 12 can slide along the slide bar 20, and the cutting length is determined according to the scale on the slide bar 20. The slide bar 20 can be a fixed length rod or a telescopic rod with a length adjustment function.
[0030] In a preferred embodiment, when the slide bar 20 has a telescopic function, the slide bar 20 includes a plurality of rods that are sequentially connected to form a telescopic structure, and the rods adjacent to the fixed splint 10 are fixedly connected to the fixed splint 10. In this way, the length of the slide bar 20 can be changed by extending and retracting the rods. Since the rods are each provided with a scale, the change in the length of the slide bar 20 can also change the cutting range, thereby improving adaptability and ease of use.
[0031] However, due to the different diameters of the rods, there may be a gap between the cutting clamp 12 and the small-diameter rod in the sliding fit, which will lead to a decrease in stability and further a decrease in cutting accuracy. To solve this technical problem, in an improved manner, the sliding rod 20 includes a first rod 201 and a second rod 202 with diameters decreasing in sequence from the fixed clamp 10 towards the cutting clamp 12. The first rod 201 is fixedly connected to the fixed clamp 10. A slider 121 is fixedly arranged on the cutting clamp 12, and a shaped hole 122 is arranged on the slider 121. The inner wall of at least part of the shaped hole 122 is in sliding fit with the first rod 201. A fitting block 18 is slidably arranged on the second rod 202, and the shape of the fitting block 18 is the same as the gap shape between the shaped hole 122 and the second rod 202, so that the slider 121 is in sliding fit with the second rod 202 through the fitting block 18. Thus, the fitting block 18 can be clamped between the shaped hole 122 and the second rod 202 to fill the gap between the shaped hole 122 and the second rod 202, and use its own rigidity to ensure the sliding stability of the cutting clamp 12, prevent the cutting clamp 12 from skewing, and ensure that the cutting clamp 12 can be stably perpendicular to the pipe fitting to be cut.
[0032] To prevent the movement of the cutting clamp 12 from exceeding the range of the sliding rod 20, in an improved embodiment, a blocking member 19 is fixedly arranged at one end of the sliding rod 20 away from the fixed clamp 10. When the cutting clamp 12 is at the limit of the range of the sliding rod 20, the blocking member 19 can abut against the cutting clamp 12 to limit the sliding of the cutting clamp 12.
[0033] In addition, in a preferred embodiment, the cutting pliers 21 include a cutting edge 210 and a driving arm 211. The cutting edge 210 is fixedly arranged on the driving arm 211, and the driving arm 211 is hinged to the cutting clamp 12. The cutting edge 210 is in the shape of a circular arc with one side open, and the opening of the cutting edge 210 faces the second bracket 14. The circular-arc cutting edge 210 can better adapt to the shape of the pipe fitting to ensure the roundness of the cut. The driving arm 211 is hinged to the cutting clamp 12. Since the hinged part is located in the middle of the driving arm 211, it can be designed as a labor-saving force arm, so that the shearing of the pipe fitting can be completed more easily.
[0034] The above schematically describes the present invention and its embodiments. This description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if those of ordinary skill in the art are inspired by it and design similar structural modes and embodiments without creative work without departing from the creative purpose of the present invention, they shall fall within the protection scope of the present invention.
