Description

Technical Field

[0001] The utility model relates to the field of clamping polyethylene pipes, in particular to a clamping device for cutting polyethylene pipes. Background Art

[0002] During the layout of water pipes, workers need to formulate a pipeline design that meets the usage requirements according to the on-site situation. Currently, PE pipes are mostly used for water supply pipes. Therefore, in some special positions, it is usually necessary to cut PE pipes. During the production or installation of polyethylene pipes, it is necessary to cut the polyethylene pipes to meet the usage requirements. Currently, among the cutting tools for polyethylene pipes on the market, they only have a simple cutting function and are single in function. At the same time, the unfixed polyethylene pipes are easily extruded and slipped during cutting, which brings difficulties to the cutting work of polyethylene pipes. Therefore, we propose a clamping device for cutting polyethylene pipes. Summary of the Utility Model

[0003] To solve the technical problem that unfixed polyethylene pipes are easily extruded and slipped during cutting, which brings difficulties to the cutting work of polyethylene pipes, the utility model provides a clamping device for cutting polyethylene pipes.

[0004] The utility model is realized by the following technical solutions: A clamping device for cutting polyethylene pipes includes an appliance main body, and the appliance main body includes a mounting bracket. A longitudinal clamping mechanism and a transverse limiting mechanism are installed inside the mounting bracket;

[0005] Among them, the longitudinal clamping mechanism includes:

[0006] An installation cavity is arranged inside the mounting bracket; an electric push rod is installed above the installation cavity; a shaft rod frame, and a shaft rod is connected to the top end of the electric push rod; a deflecting shaft rod, one end of the deflecting shaft rod is clamped inside the shaft rod frame; an axial center bolt passes through the shaft rod frame and the deflecting shaft rod; there are two groups of deflecting shaft rods, and the connection part of the two groups of deflecting shaft rods is connected to the shaft rod frame, and the axial center bolt passes through the two groups of deflecting shaft rods; a movable rod, the movable rod is connected to the bottom end of the deflecting shaft rod; one end of the movable rod is connected to the deflecting shaft rod, and the other end is connected to a deflecting frame, and the movable rod passes through the mounting bracket; a movable axial center passes through the deflecting shaft rod and the movable rod; a deflecting frame, the bottom end of the deflecting frame is connected to the movable rod; a deflecting axial center passes through the movable rod and the deflecting frame; a clamping rod is installed at the top end of the deflecting frame; an adjusting bolt passes through the connection part of the deflecting frame and the clamping rod.

[0007] Through the operation of the electric push rod, the electric push rod contracts, the electric push rod drives the shaft rod frame downward, the shaft rod frame drives the central axis bolt downward, the central axis bolt drives the deflecting shaft rod, the deflecting shaft rod pushes the movable rod outward, the movable rod then pushes the deflecting frame outward, the bottom end of the deflecting frame deflects around the deflection axis, the central position of the deflecting frame deflects around the adjusting bolt, and the clamping rod connected to the top end of the deflecting frame deflects. Thus, the two sets of opposite clamping rods fixedly clamp the top part of the polyethylene pipe, ensuring the stability of the polyethylene pipe and facilitating the cutting of the polyethylene pipe.

[0008] As a further improvement of the above solution, there are two sets of clamping rods arranged oppositely, and the two sets of clamping rods clamp the polyethylene pipe.

[0009] As a further improvement of the above solution, the lateral limiting mechanism includes:

[0010] A loading platform, which is installed on the supporting bottom plate; a working motor, which is a forward and reverse motor and is a prior art; a driving screw rod, which is connected to the working motor; a moving limiting block, the bottom end of which is sleeved on the surface of the driving screw rod; a positioning block, which is installed above the loading platform.

[0011] Place the polyethylene pipe above the lateral limiting mechanism. Through the operation of the working motor, the working motor drives the connected driving screw rod to rotate, and the driving screw rod thus drives the connected moving limiting block to move synchronously. The moving limiting block thus moves towards the positioning block, and the moving limiting block and the positioning block thus limit the bottom end of the polyethylene pipe.

[0012] As a further improvement of the above solution, the bottom ends of the moving limiting block and the positioning block are both provided with arcs, and the driving screw rod drives the moving limiting block to move horizontally.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, the clamping rod connected to the top end of the deflecting frame deflects, and the two sets of opposite clamping rods thus fixedly clamp the top part of the polyethylene pipe, ensuring the stability of the polyethylene pipe and facilitating the cutting of the polyethylene pipe.

[0015] 2. In the present utility model, through the operation of the working motor, the working motor drives the connected driving screw rod to rotate, and the driving screw rod thus drives the connected moving limiting block to move synchronously. The moving limiting block thus moves towards the positioning block, and the moving limiting block and the positioning block thus limit the bottom end of the polyethylene pipe.

[0031] Movable axis 37 passes through the deflecting shaft rod 34 and the movable rod 36;

[0032] Deflecting frame 38, the bottom end of the deflecting frame 38 is connected to the movable rod 36;

[0034] Clamping rod 310 is installed at the top end of the deflecting frame 38; there are two sets of clamping rods 310 in a relative state, and the two sets of clamping rods 310 clamp the polyethylene pipe 5;

[0035] Adjusting bolt 311 passes through the connection of the deflecting frame 38 and the clamping rod 310.

[0036] Through the operation of the electric push rod 32, the electric push rod 32 contracts, the electric push rod 32 drives the shaft rod frame 33 to move downward, the shaft rod frame 33 drives the axial bolt 35 to move downward, the axial bolt 35 drives the deflecting shaft rod 34 to move, the deflecting shaft rod 34 pushes the movable rod 36 outward, the movable rod 36 then pushes the deflecting frame 38 outward, the bottom end of the deflecting frame 38 deflects around the deflecting axis 39, the center position of the deflecting frame 38 deflects around the adjusting bolt 311, and the clamping rod 310 connected to the top end of the deflecting frame 38 deflects.
