Description

Technical Field

[0001] The utility model relates to the technical field of pipeline processing, in particular to an adjustable pipeline cutting device. Background Art

[0002] A pipeline is a tubular structure that transports fluids or substances to a target location. The size of the pipeline varies depending on the application scenario and requirements. Pipes used in different industries and engineering projects may have different parameters such as diameter, wall thickness and length. Therefore, in order to meet different engineering needs, the cutting device needs to be able to adapt to pipes of different sizes.

[0003] The Chinese patent "An adjustable PVC pipe cutting device" authorization announcement number "CN210850500U" can move left and right on the slide rail by removing the translation restriction of the horizontal slider, thereby driving the clamp wheel connecting shaft to move horizontally. When it moves to the appropriate position, release the control button to make the push-up block re-engage with the card block. By improving the structure of the equipment, the distance between the clamp wheels on the placement table can be freely adjusted when it is in use, which is convenient for placing and cutting PVC pipes of various sizes.

[0004] However, when the clamping wheels are used to fix pipes of different diameters, the heights of the two clamping wheels remain unchanged. When the pipe diameter is small, the clamping wheels fix the upper surface of the pipe, and when the pipe diameter is large, the clamping wheels fix the lower surface of the pipe. As a result, the stability of pipes of different diameters during cutting and positioning cannot be guaranteed, which affects the cutting effect of the pipes.

[0005] Therefore, an adjustable pipe cutting device is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an adjustable pipe cutting device in order to solve the above-mentioned problem, which improves the problem that when the pipe diameter is small, the clamping wheel fixes the upper surface end of the pipe, and when the pipe diameter is large, the clamping wheel fixes the lower surface end of the pipe, thereby failing to ensure the stability of pipes of different diameters during cutting and positioning, affecting the cutting effect of the pipe.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: an adjustable pipe cutting device, comprising: a base, one side of the base is fixedly connected to a mounting frame, the inner wall of the mounting frame is fixedly connected to an electric push rod, the bottom end of the electric push rod is provided with a cutting machine body, and the top end of the base is provided with a limiting mechanism; wherein, the limiting mechanism comprises a bidirectional screw rod rotatably connected to the inner wall of the base, the top end of the base is slidably connected to two moving plates, the inner wall of the moving plate is slidably connected to a fixing frame, the inner wall of the fixing frame is rotatably connected to a limiting wheel, and the top end of the base is provided with a limiting component.

[0008] Preferably, the limit assembly includes two connecting rods hinged to the top of the base, the top of the connecting rod is hinged to the upper end of one side of the fixed frame, the top of the base is fixedly connected to a fixed frame, the inner wall of the fixed frame is slidably connected to a cylinder, the inner wall of the cylinder is slidably connected to a moving rod, one end of the moving rod passes through the cylinder and is fixedly connected to a limit plate, the surface of the moving rod is fixedly connected to a round rod, and the other end of the round rod is fixedly connected to the surface of the fixed frame. Two second sliders are fixedly connected to the bottom end of the moving plate, and the inner wall of one of the second sliders is threadedly connected to the surface of the bidirectional screw. When the fixed frame moves, the moving rod drives the limit plate to move synchronously under the action of the round rod, so that the limit wheel limits the pipeline while the limit plate simultaneously realizes the limit operation of the pipeline, which improves the consistency of the device during operation and strengthens the stability of the pipeline limit.

[0009] Preferably, the inner wall of the fixed frame is provided with two slide grooves, the inner wall of the slide groove is slidably connected with a first slider, and the cylinder is fixedly connected between the opposite sides of the two first sliders. The cooperation between the slide groove and the first slider is conducive to limiting the cylinder and preventing the cylinder from moving.

[0010] Preferably, the other side of the limit plate is rotatably connected to rollers distributed in equal rows. When the pipeline rotates, the rollers are driven to rotate synchronously, thereby reducing the friction between the pipeline rotation and the limit plate when the limit plate limits the pipeline.

[0011] Preferably, one end of the bidirectional screw rod passes through the base and is fixedly connected to a twisting wheel, and the surface of the twisting wheel is fixedly connected to protrusions distributed in an annular shape. The twisting wheel makes the operation more convenient, and the protrusions on the twisting wheel surface increase the friction between the operator and the twisting wheel surface when the operator rotates, thereby avoiding slipping.

[0012] Preferably, two supporting frames are fixedly connected to the middle of the top of the base, and the top of the supporting frame is arc-shaped. When fixing the pipeline, the supporting frame is used to perform preliminary positioning, thereby improving the stability of the positioning wheel and the positioning plate in the process of positioning the pipeline.

[0013] Preferably, the top of the support frame is provided with a plurality of spherical grooves, and the inner wall of the spherical groove is rotatably connected with a ball. When the pipe is rotated for cutting, the ball is driven to rotate in the spherical groove, thereby reducing the friction force when the pipe rotates.

[0014] The beneficial effects of the utility model are:

[0015] 1. When limiting the position of different pipe diameters, under the action of the bidirectional screw, the two limiting wheels move synchronously and approach each other, which is conducive to the centering of the pipe. At the same time, when limiting the position of pipes with different diameters, the movement of the moving plate and the cooperation of the connecting rod are conducive to the upward tilt and downward movement of the limiting wheel in the horizontal direction, which is conducive to the limiting wheel limiting the position of pipes with different diameters. The surface of the limiting wheel is always in contact with the middle of the surface of the pipe, thereby ensuring the stability of the fixing of pipes with different diameters and improving the cutting effect of the pipe;

[0016] 2. When the fixed frame moves, the limit plate is driven to move synchronously through the moving rod under the action of the round rod, so that the limit wheel limits the pipeline while the limit plate simultaneously limits the pipeline, which improves the consistency of the device during operation and strengthens the stability of the pipeline when limiting.

[0017] 3. When fixing the pipeline, use the support frame to perform preliminary limiting on the fixation to improve the stability of the pipeline during the limiting process of the pipeline by the limiting wheel and the limiting plate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, an adjustable pipe cutting device includes: a base 1, a mounting frame 2 is fixedly connected to one side of the base 1, an electric push rod 3 is fixedly connected to the inner wall of the mounting frame 2, a cutting machine body 4 is arranged at the bottom end of the electric push rod 3, and a limiting mechanism 5 is arranged at the top of the base 1; wherein the limiting mechanism 5 includes a bidirectional screw rod 501 rotatably connected to the inner wall of the base 1, two moving plates 502 are slidably connected to the top of the base 1, a fixed frame 503 is slidably connected to the inner wall of the moving plate 502, a limiting wheel 504 is rotatably connected to the inner wall of the fixed frame 503, and a limiting component 505 is arranged at the top of the base 1.

[0026] The cutting machine body 4 includes a motor and a cutting blade {the cutting blade can be selected according to the required cutting pipe}, the bottom end of the electric push rod 3 is fixedly connected to a connecting plate, and the bottom end of the connecting plate is fixedly connected to the motor. When it is necessary to cut the pipe, after the pipe is fixed, the electric push rod 3 is started, and the telescopic end of the electric push rod 3 pushes the cutting machine body 4 downward through the connecting plate, so that the surface of the cutting blade contacts the surface of the pipe, and the motor is started. The output shaft of the motor rotates to drive the cutting blade to rotate. At this time, the pipe is rotated, and the cutting blade cuts the pipe.

[0027] It should be noted that: in the initial state of the device, the distance between the two limiting wheels 504 is the fixed maximum pipe diameter. When the two limiting wheels 504 fix the maximum diameter pipe, the surface of the pipe limiting wheel 504 contacts the middle of the pipe surface to achieve the limiting operation of the pipe.

[0028] like Figure 2, Figure 3 and Figure 4 As shown, the limiting assembly 505 includes two connecting rods 5051 hinged to the top of the base 1, the top of the connecting rod 5051 is hinged to the upper end of one side of the fixed frame 503, the top of the base 1 is fixedly connected to a fixed frame 5052, the inner wall of the fixed frame 5052 is slidably connected to a cylinder 5053, the inner wall of the cylinder 5053 is slidably connected to a moving rod 5054, one end of the moving rod 5054 passes through the cylinder 5053 and is fixedly connected to a limiting plate 5055, the surface of the moving rod 5054 is fixedly connected to a round rod 5056, and the other end of the round rod 5056 is fixedly connected to the surface of the fixed frame 503. Two slide grooves 5057 are provided on the inner wall of the fixed frame 5052, the inner wall of the slide groove 5057 is slidably connected to a first slider 5058, and the cylinder 5053 is fixedly connected between the opposite sides of the two first sliders 5058. The other side of the limiting plate 5055 is rotatably connected to rollers 5059 distributed in equal rows. One end of the bidirectional screw rod 501 passes through the base 1 and is fixedly connected to a toggle 50510, and a ring-shaped protrusion is fixedly connected to the surface of the toggle 50510. Two second sliders 50511 are fixedly connected to the bottom end of the moving plate 502, and the inner wall of one of the second sliders 50511 is threadedly connected to the surface of the bidirectional screw rod 501.

[0029] Since the distance between the two limiting wheels 504 is the maximum pipe diameter distance, the pipe diameter placed between the two limiting wheels 504 is less than or equal to the maximum pipe diameter. When cutting pipes of different diameters less than the maximum pipe diameter between the two limiting wheels 504, the pipe to be cut is placed between the two limiting wheels 504. At this time, the knob 50510 is rotated. When the knob 50510 is rotated, the bidirectional screw rod 501 is driven to rotate. A moving groove matching the second slider 50511 is provided at the top of the base 1. The bidirectional screw rod 501 is arranged in one of the moving grooves. When the bidirectional screw rod 501 is rotated, the second slider 50511 at the bottom of the two moving plates 502 is driven to move and approach each other, thereby driving the two moving plates 502 to approach each other. When the moving plate 502 moves, the bottom end of the fixed frame 503 is pulled into the moving plate 502 under the action of the connecting rod 5051, thereby driving the limiting wheel 5 04 moves downward, thereby causing the limiting wheel 504 to move downward while moving horizontally. When the movable plate 502 moves, when the limiting wheel 504 contacts the middle of the surface of the required limiting pipe during the process of tilting downward, the limiting wheel 504 cannot move at this time, and stops rotating the bidirectional screw rod 501, so that when the limiting wheel 504 limits the diameter of different pipes, the limiting wheel 504 is located in the middle of the required fixed pipe. At the same time, when the fixed frame 503 moves downward, the moving rod 5054 is driven by the action of the round rod 5056 to make the cylinder 5053 move downward synchronously in the fixed frame 5052. At the same time, when the fixed frame 503 moves horizontally, the moving rod 5054 is driven by the round rod 5056 to move horizontally synchronously, so that the limiting plate 5055 drives the surface of the roller 5059 to contact the surface of the pipe, and the pipe is limited, thereby improving the stability of the pipe limitation.

[0030] like Figure 2 and Figure 5 As shown, two supporting frames 506 are fixedly connected to the middle of the top of the base 1, and the top of the supporting frame 506 is in an arc shape. The top of the supporting frame 506 is provided with a plurality of spherical grooves 5061, and the inner wall of the spherical groove 5061 is rotatably connected with a round ball 5062.

[0031] One of the supporting frames 506 is located between the two limiting wheels 504, and the other supporting frame 506 is located between the two fixing frames 5052. When the pipeline needs to be cut, the pipeline is placed on the two supporting frames 506 to support the pipeline.

[0032] When the utility model is in use, when cutting pipes of different diameters, the pipes to be cut are placed on the two supporting frames 506. At this time, the turning knob 50510 is rotated to drive the bidirectional screw rod 501 to rotate, and the second slider 50511 at the bottom of the movable plate 502 drives the two movable plates 502 to approach each other. At the same time, when the movable plate 502 moves, the bottom end of the fixed frame 503 is pulled into the movable plate 502 under the action of the connecting rod 5051, thereby driving the limiting wheel 504 to move downward. When the movable plate 502 moves, the limiting wheel 504 moves downward in a tilted downward movement. When it contacts the middle of the surface of the required limited pipe, the limiting wheel 504 cannot move and stops rotating the bidirectional screw rod 501, so that when the limiting wheel 504 limits the different pipe diameters, the limiting wheel 504 is located in the middle of the required fixed pipe, thereby ensuring the stability when fixing pipes of different diameters. At the same time, when the fixing frame 503 moves, the limiting plate 5055 is synchronously driven to move through the moving rod 5054 under the action of the round rod 5056, so that when the limiting wheel 504 limits the pipe, the limiting plate 5055 simultaneously realizes the limiting operation of the pipe, thereby improving the stability of the pipe limiting.

[0033] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
