Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1
[0029] In existing technologies, different clamps are required to fix pipe fittings of different shapes, such as cylindrical and flat pipes. However, existing pipe cutting machine clamps are often only suitable for pipe fittings of a single shape. In actual operation, due to the diversity of pipe fitting shapes, operators have to frequently change clamps, which not only increases the complexity of operation but also reduces work efficiency.
[0030] Therefore, in order to solve the above problems and improve the applicability of the clamp and the efficiency of pipe cutting, this utility model discloses a pipe clamping mechanism, see reference. Figure 1 and Figure 2The system includes a workbench, the top of which is provided with a clamping part 3, which is suitable for clamping pipe fittings. The clamping part 3 includes: an upper clamping block 16, the interior of which has a cavity extending along the height direction of the upper clamping block 16, and the bottom of the upper clamping block 16 has a connecting interface 17 communicating with the cavity; and a lower clamping block 18, located at the bottom of the upper clamping block 16, and the top of the lower clamping block 18 is provided with a connecting rod 19, which passes through the connecting interface 17 into the cavity. The upper clamping block 16 and the lower clamping block 18 are both right-angle bent structures, and the front end of the bend of the upper clamping block 16 and the lower clamping block 18 are provided with an arc-shaped recess. When the connecting rod 19 is connected to the cavity, the bends of the upper clamping block 16 and the lower clamping block 18 are relatively distributed and form a second clamping groove 14, and a first clamping groove 13 is formed between the arc-shaped recesses at the front ends of the two bends.
[0031] In this embodiment, the first clamping groove 13 and the second clamping groove 14 enable the pipe clamping mechanism to clamp pipes of different shapes. Specifically, when the pipe is cylindrical, it can be placed in the first clamping groove 13, and the upper clamping block 16 and the lower clamping block 18 can be used to stably clamp the pipe. When the pipe is flat, it can be placed in the second clamping groove 14, and the relative positions of the upper clamping block 16 and the lower clamping block 18 can be adjusted to achieve effective clamping of the pipe. This design greatly improves the applicability of the clamp, allowing the operator to complete the clamping operation of pipes of different shapes without frequently changing the clamp.
[0032] To further improve the stability and flexibility of clamping, corresponding connection holes are provided on the surfaces of the interface 17 and the docking rod 19 in this embodiment, and a connector 15 adapted to the connection holes is provided at the bottom of the upper clamping block 16. By fixing the interface 17 and the docking rod 19 together with the connector 15, it can be ensured that the upper clamping block 16 and the lower clamping block 18 will not move relative to each other when clamping the pipe, thereby improving the stability of clamping.
[0033] Furthermore, the upper surface of the docking rod 19 has multiple connection holes, and these multiple connection holes 19 are distributed along the length of the docking rod 19. Users can select different connection holes to correspond to the connection holes on the inner wall of the docking interface 17 and fix them with the connector 15 to fine-tune the relative positions of the upper clamping block 16 and the lower clamping block 18 to adapt to pipes of different lengths or sizes, further enhancing the flexibility and practicality of the clamping mechanism.
[0034] Furthermore, the pipe clamping mechanism in this embodiment also includes components such as a first fixed plate 1, a moving part 2, and a first lead screw 4. The first fixed plate 1 is fixedly connected to the top of the workbench, providing stable support for the clamping part 3. The moving part 2 is located at the bottom of the clamping part 3, and the first lead screw 4 is provided between the moving part 2 and the first fixed plate 1. By rotating the first lead screw 4, the distance between the moving part 2 and the first fixed plate 1 can be adjusted, thereby realizing the adjustment of the distance between the clamping parts 3.
[0035] It should be noted that the first lead screw 4 is a bidirectional lead screw with both positive and negative threads, and there are two moving parts 2. The two moving parts 2 are respectively threaded to the two ends of the bidirectional lead screw with both positive and negative threads. Therefore, when the first lead screw 4 is rotated, the two moving parts 2 can move in opposite or the same direction at the same time, thereby adjusting the distance between the clamping parts 3 at the top of the two moving parts 2 for clamping the pipe fitting.
[0036] In addition, each moving part 2 is provided with two clamping parts 3 at its top. The two clamping parts 3 are arranged in a straight line opposite each other at the top of the moving part 2, and there is a gap on the side of the two clamping parts 3 facing each other, which forms a cutting groove 12.
[0037] It is understandable that the clamping parts 3 at the top of the two moving parts 2 are arranged opposite each other with the first and second clamping grooves on one side. When the two moving parts 2 move towards each other, the first clamping groove 13 or the second clamping groove 14 on the two clamping parts 3 clamps the pipe. At this time, the cutting groove 12 exposes the part of the pipe that needs to be cut, providing a precise cutting position for subsequent cutting operations.
[0038] The first fixing plate 1 has a baffle 5 on its top. The baffle 5 is inclined and located above the cutting groove 12. The baffle 5 effectively prevents waste or debris from splashing during the cutting process, thereby improving operational safety. At the same time, the inclined baffle 5 also facilitates the sliding and collection of waste or debris, keeping the working environment clean.
[0039] Example 2
[0040] Based on Embodiment 1, in order to maintain the stability of the moving part 2 during movement, the second fixing plate 8 is provided on the side of the moving part 2 away from the first fixing plate 1, and a guide post 11 is provided between the first fixing plate 1 and the second fixing plate 8, which is inserted into the moving part 2.
[0041] In this embodiment, the guide post 11 effectively restricts the movement trajectory of the moving part 2, preventing it from deviating or swaying during movement, thereby improving the overall stability and clamping accuracy of the pipe clamping mechanism. Simultaneously, the guide post 11 also guides the moving part 2, enabling it to move smoothly along a predetermined path, further ensuring the successful execution of the pipe clamping operation.
[0042] Example 3
[0043] Based on Embodiments 1 and 2, this application also provides a cutting device, which includes the aforementioned pipe clamping mechanism, a cutting blade 6, and a lifting unit 7. The cutting blade 6 is located above the cutting groove 12 and is used to cut the pipe. The lifting unit 7 is connected between the cutting blade 6 and the second fixed plate 8, and achieves the cutting of the pipe by driving the cutting blade 6 to move up and down.
[0044] Specifically, the lifting unit 7 includes a second lead screw 9 and a moving arm. The moving arm is connected to the cutting blade 6. The second lead screw 9 is mounted on the second fixed plate 8 and extends along the height direction of the second fixed plate 8. By rotating the second lead screw 9, the moving arm and the cutting blade 6 can be driven to move up and down along the length direction of the second lead screw 9, thereby realizing the cutting of the pipe.
[0045] In addition, to further improve the stability and cutting accuracy of the cutting device, this embodiment also provides a sliding groove on the side of the second fixed plate 8 facing the cutting blade 6, which is located in the same length direction as the second lead screw 9. A limiting block 10 is provided at the end of the moving arm away from the cutting blade 6, and the limiting block 10 is slidably connected within the sliding groove. Through the cooperation of the limiting block 10 and the sliding groove, the movement trajectory of the moving arm can be further restricted, preventing it from deviating or swaying during lifting and lowering, thereby improving the stability and cutting accuracy of the cutting device.
[0046] It should be noted that the cutting blade 6 is a disc-shaped blade with serrations, which is driven to rotate by an external motor. The first lead screw 4 and the second lead screw 9 can be driven manually or electrically to meet different operating requirements. The above driving methods are all existing technologies and will not be described in detail below.
[0047] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0048] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
