Description

Technical Field

[0001] This utility model relates to the field of cutting technology, and more specifically, to a clamping device for cutting square and rectangular tubes. Background Technology

[0002] In existing technologies, the design of clamping devices for cutting rectangular tubes usually adopts a fixed clamping sleeve position. Although this design can ensure that the clamping sleeve is stably fixed in a certain position, it also brings several significant problems, especially in terms of the convenience and efficiency of installing and removing the clamping sleeve.

[0003] Since the position of the clamping sleeve is usually fixed, the operator must accurately place the rectangular tube into the correct position each time it is used. If the position of the clamping sleeve is not designed to be adjustable or easy to operate, the installation and disassembly process becomes quite troublesome. This not only increases the difficulty of the operator's work, but may also lead to inaccurate positioning of the rectangular tube during installation, affecting the cutting effect.

[0004] In traditional fixed clamping sleeve designs, operators need to manually or with tools disassemble or install the clamping sleeve into the clamping device. This not only requires a high level of operational skill but also increases the uncertainty of manual operation. For example, when installing the clamping sleeve, operators need to precisely align multiple connecting parts to ensure that the clamping sleeve is in the correct installation position. Similarly, disassembly requires following a specific procedure and may take a long time to loosen, disassemble, and reassemble. This cumbersome process undoubtedly reduces work efficiency, especially in the case of mass production or multiple processes, further exacerbating time costs. Utility Model Content

[0034] Please see Figures 1-5As a supplementary embodiment of a rectangular tube cutting clamping device, which includes a rectangular tube guide clamping mechanism, a quick clamping mechanism, and a clamping auxiliary mechanism: A cutting component 19 is installed at the top end of the base frame 1, and one end of the cutting component 19 can press against the tube to be cut on the guide support plate 2. An adjusting frame 20 is rotatably installed on one side of the top end of the base frame 1, and a bolt hole 21 is installed on the adjusting frame 20. The bolt hole 21 is a rectangular opening, and an external bolt can pass through the bolt hole 21 and the bottom end of the guide support plate 2 to adjust the adjusting frame 20. Fixed to the guide plate 2, the placement frame 3 is equipped with adjustment plates 22 on both sides, and adjustment holes 23 are provided on the adjustment plates 22. Multiple sets of adjustment holes 23 are provided. Side plates 24 are installed on both sides of the sliding sleeve 5.

A cutting table 25 is installed at the top end of one end of the guide plate 2, and the cutting table 25 is arranged parallel to the placement frame 3. The workpiece to be cut is guided to the cutting table 25 through the placement frame 3.

[0035] More specifically, the rectangular tube to be cut is placed on the placement rack 3, which is fixed by the guide plate 2 and is adjustable in position. The rectangular tube is guided to the appropriate position on the placement rack 3 to ensure that it enters the cutting area. The hydraulic cylinder 6 is activated, pushing the sliding sleeve 5 to slide along the sliding groove 4. The position of the placement rack 3 is adjusted so that the rectangular tube is tightly connected with the clamping plate 7. The force of the hydraulic cylinder 6 presses the rectangular tube firmly on the placement rack 3 to ensure that the rectangular tube is stable and does not move. The clamping auxiliary mechanism provides additional clamping force through the compression spring 14 and the rotating plate 15 to ensure that the rectangular tube does not shift or loosen during the cutting process. Once the rectangular tube is firmly clamped, the cutting assembly 19 starts to work. After the cutting is completed, the force of the hydraulic cylinder 6, the clamping rod 9 and the auxiliary mechanism is released, and the rectangular tube can be removed from the clamping device for the next operation or processing.

[0036] In summary, when the overall equipment is in use or operation: when the rectangular tube guide clamping mechanism is required, the rectangular tube guide clamping mechanism realizes the precise guidance and clamping of the workpiece. The guide plate 2 is rotatably connected to the base frame 1 through the adjusting frame 20. The angle can be fixed by the bolt holes 21 and bolts. The placement frame 3 is fixed on the guide plate 2. The sliding grooves 4 on both sides cooperate with the sliding sleeve 5 to form an adjustable clamping system. The hydraulic cylinder 6 is installed on the top of the sliding sleeve 5 and applies pressure to the workpiece through the clamping plate 7. The cutting table 25 is set parallel to the placement frame 3 to ensure that the workpiece is smoothly transported to the cutting position. The multiple sets of adjusting holes 23 on the adjusting plate 22 provide different position fixing options.

[0037] When the quick-locking mechanism is required to operate, it provides precise locking of position. The locking rod 9 can extend into the inside of the locking tube 8, and the locking groove 10 on its side wall and the extension frame 11 form a locking mechanism. The rotating sleeve 12 is limited to rotating on the side wall of the locking tube 8, and the guide groove 13 on the inner wall cooperates with the extension frame 11. Through the rotation of the rotating sleeve 12, the guide groove 13 pushes the extension frame 11 to move laterally, realizing engagement or disengagement with the locking groove 10, thereby completing the locking or unlocking operation. The side plate 24 connects the locking tube 8 and the sliding sleeve 5 to ensure the stability of the entire locking system.

[0038] When the snap-fit ​​auxiliary mechanism is required to operate, it provides stable rotation control. The compression spring 14 is installed on the top of the inner wall of the snap-fit ​​tube 8 and is compressed when the snap-fit ​​rod 9 is inserted, providing a stabilizing force. The rotating plate 15 is installed on the top of the rotating sleeve 12, and the spring rod 18 slides laterally on the rotating plate 15. The multiple sets of rod holes 17 on the fixing ring 16 cooperate with the spring rod 18 to realize the step-by-step stable rotation of the rotating sleeve 12, which not only ensures the accuracy of rotation but also provides a reliable positioning function.

[0039] The rectangular tube to be cut is placed on the placement rack 3, which is fixed by the guide plate 2 and its position is adjustable. The rectangular tube is guided to the appropriate position on the placement rack 3 to ensure that it enters the cutting area. The hydraulic cylinder 6 is activated, pushing the sliding sleeve 5 to slide along the sliding groove 4. The position of the placement rack 3 is adjusted so that the rectangular tube is tightly connected with the clamping plate 7. The force of the hydraulic cylinder 6 presses the rectangular tube firmly on the placement rack 3 to ensure that the rectangular tube is stable and does not move. The clamping auxiliary mechanism provides additional clamping force through the compression spring 14 and the rotating plate 15 to ensure that the rectangular tube does not shift or loosen during the cutting process. Once the rectangular tube is firmly clamped, the cutting assembly 19 starts to work. After the cutting is completed, the force of the hydraulic cylinder 6, the clamping rod 9 and the auxiliary mechanism is released, and the rectangular tube can be removed from the clamping device for the next operation or processing.
