Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe processing technology, and in particular to an adjustable clamp for corrugated pipe processing. Background Technology

[0002] Because of its flexibility, foldability, and extensibility, corrugated pipes are widely used in industries such as chemical, power, and civil engineering. Depending on the application of the corrugated pipes, they often need to be processed, and clamps are required to fix them during the processing.

[0003] Currently, existing clamps often fix bellows by applying force from the outside in. However, due to the special corrugated structure on the outside of the bellows, the external structure of the pipe is easily damaged by clamps that apply external force, which is not conducive to subsequent processing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing an adjustable clamp for bellows processing, thereby solving the problems mentioned in the background section.

[0005] An adjustable clamp for processing corrugated pipes includes a worktable and an internal support clamping mechanism and a support assembly mounted on the worktable. The internal support clamping mechanism includes an electric cylinder, a bracket, a fixed rod, a limiting end, an adjusting part, a connecting arm, a drive ring, a lead screw, a motor, and a fixing frame. The bracket is arranged in two sets, one set fixed to the worktable and the other set sliding along the surface of the worktable. The electric cylinder is mounted on the worktable, and its output end is fixedly connected to the movable bracket set. The fixed rod is arranged in two sets, respectively fixed to the opposite surfaces of the upper ends of the two sets of brackets. The limiting end is fixed to the end of the fixed rod. The adjusting part consists of three grooves respectively rotatably mounted on the limiting end. The motor is fixedly mounted to the end of the limiting end through the fixing frame. The lead screw is fixedly mounted at the output end of the motor and inserted into the middle of the limiting end for rotation. The drive ring is drivenly connected to the lead screw. The two ends of the connecting arm are respectively hinged to the drive ring and the adjusting part.

[0006] By adopting the above technical solution, the corrugated pipe can be internally supported and clamped, which facilitates the processing of the corrugated pipe and avoids clamping the corrugated pipe from the outside, thus preventing clamping deformation.

[0007] The supporting component includes a support platform, a screw, and a limiting part. The support platform is set along a groove on the worktable by the limiting part. The screw is fixed to the bottom surface of the support platform and the downward freedom of the support platform is restricted by a nut.

[0008] By adopting the above technical solution, the middle part of the corrugated pipe is supported.

[0009] The limiting part is provided in four places, distributed at the four corners of the bottom surface of the support platform. The limiting part is composed of a fixed column and a slider. The slider slides along the slide groove of the worktable, and the fixed column passes through the slider.

[0010] By adopting the above technical solution, the position of the support platform can be adjusted to support the middle part of the corrugated pipe, which is convenient for subsequent processing.

[0011] A soft pad is also fixedly provided at one end of the adjustment part near the connecting arm. When the two sides of the adjustment part are attached to the inner wall of the groove, the adjustment part is in a horizontal state, and the upper surface of the soft pad and the outer surface of the limiting end are on the same arc surface.

[0012] By adopting the above technical solution, the soft pad can protect the inside of the corrugated pipe while the corrugated pipe is internally supported and clamped.

[0013] The center point of the adjustment unit and the center point of the support platform are located on the same water cross section.

[0014] By adopting the above technical solution, the corrugated pipe is ensured to be centered, clamped, and supported.

[0015] The beneficial effects of this adjustable clamp for bellows processing are:

[0016] It can be adjusted in real time according to the different lengths and diameters of the corrugated pipe, so as to realize the internal support and clamping of the corrugated pipe and the external processing of the corrugated pipe. This reduces the obstruction of the clamps, makes the processing more convenient, and avoids the corrugated pipe being clamped from the outside, which would cause clamping deformation.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Reference Figure 1-4 An adjustable clamp for processing corrugated pipes includes a worktable 1 and an inner support clamping mechanism and a support assembly mounted on the worktable 1. The inner support clamping mechanism includes an electric cylinder 2, a bracket 3, a fixed rod 7, a limiting end 8, an adjusting part 9, a connecting arm 10, a drive ring 11, a lead screw 12, a motor 13, and a fixing frame 14. The bracket 3 is arranged in two sets, one set is fixed on the worktable 1, and the other set is slidably arranged along the surface of the worktable 1. The electric cylinder 2 is mounted on the worktable 1, and its output end is connected to the movable set of bracket 3. The fixed connection consists of two sets of fixed rods 7, which are respectively fixed to the opposite surfaces of the upper ends of the two sets of brackets 3. The limiting end 8 is fixed to the end of the fixed rod 7. The adjusting part 9 consists of three parts that are rotatably installed in the groove 801 of the limiting end 8. The motor 13 is fixedly installed at the end of the limiting end 8 through the fixing bracket 14. The lead screw 12 is fixedly installed at the output end of the motor 13 and inserted into the middle of the limiting end 8 for rotation. The drive ring 11 is connected to the lead screw 12 for transmission. The two ends of the connecting arm 10 are respectively hinged to the drive ring 11 and the adjusting part 9.

[0024] The two ends of the bellows can be respectively fitted onto the two limiting ends 8. The electric cylinder 2 can be driven to adjust the movable set of brackets 3 appropriately. At this time, the motor 13 can be driven to drive the drive ring 11 to move through the lead screw 12. When the drive ring 11 moves in the direction of the motor 13, it will drive the connecting arm 10 to move. At this time, during the movement, the connecting arm 10 will gradually push the adjusting part 9, so that the end with the soft pad 901 is pushed out from the groove 801 and the soft pad 901 is in contact with the inner wall of the bellows. Thus, the adjusting part 9 can internally support and clamp the bellows from the inside.

[0025] The height of the support platform 4 can then be adjusted so that it supports the bottom of the bellows. The nut on the screw 5 is rotated to restrict the screw 5 from moving downward, thus completing the support of the bellows by the support platform 4.

[0026] The supporting assembly includes a support platform 4, a screw 5, and a limiting part 6. The support platform 4 is set along a groove on the workbench 1 via the limiting part 6. The screw 5 is fixed to the bottom surface of the support platform 4, and the downward freedom of the support platform 4 is restricted by a nut. The upper surface of the support platform 4 is set with an arc-shaped structure. According to the length of the insulation pipe, the movable limiting part 6 can slide along the groove on the workbench 1, so that the support platform 4 moves to the lower part of the middle of the corrugated pipe. Then, the nut on the screw 5 is rotated to abut against the workbench 1, restricting the downward freedom of the screw 5. Thus, the middle part of the corrugated pipe can be supported by the support platform 4.

[0027] A soft pad 901 is fixedly provided at one end of the adjusting part 9 near the connecting arm 10. When the two sides of the adjusting part 9 are attached to the inner wall of the groove 801, the adjusting part 9 is in a horizontal state, and the upper surface of the soft pad 901 and the outer surface of the limiting end 8 are on the same arc surface. The center point of the adjusting part 9 and the center point of the support platform 4 are set on the same water cross section. While the corrugated pipe is internally supported and clamped, the soft pad 901 can protect the inside of the corrugated pipe, ensuring that the corrugated pipe is centrally clamped and supported.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
