Description

Technical Field

[0001] The utility model relates to the field of pipe fitting clamping equipment, in particular to a clamping and fastening device for polyethylene pipe fitting processing. Background Technique

[0002] The polyethylene pipe is also called PE pipe. When processing pipe fittings, clamping and fixing are required. Since the lengths of the pipe fittings are different, it is impossible to clamp and fix pipe fittings of different lengths, and it is impossible to perform multi-point clamping during the clamping of pipe fittings, so the phenomenon of pipe fitting bending cannot be avoided.

[0003] According to the pipe fitting clamping device disclosed in the patent document with the existing publication number CN213828049U, it includes a first fixed seat and a screw rod. The first fixed seat is fixedly connected with a plurality of first fixed claws at intervals, and further includes a second fixed seat. The second fixed seat is fixedly connected with a plurality of second fixed claws at intervals. The orthographic projections of the first fixed claws and the second fixed claws on a vertical plane are staggered. The screw rod passes through the first fixed seat and the second fixed seat respectively. When this technical solution is used, by adjusting the distance between the first fixed seat and the second fixed seat, the distance between the first fixed claws and the second fixed claws is changed. Moreover, the orthographic projections of the first fixed claws and the second fixed claws on the same vertical plane are staggered, so that the first fixed claws and the second fixed claws can clamp pipe fittings of different diameters, improving the versatility of the pipe fitting clamping device. For the above technical solution, although the clamping of the pipe fittings is realized, the clamping point positions are fixed, and multi-point clamping of the pipe fittings cannot be realized, which is inconvenient in use. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a clamping and fastening device for polyethylene pipe fitting processing to solve the problems raised in the above background technique. The structure of the utility model is novel. When in use, the support seat and the fixed seat are distributed in a front-back dislocation manner. The pipe fitting is placed on the arc seat for multi-point support clamping. After clamping, the support area of the pipe fitting is increased to complete the horizontal support for the longer pipe fitting.

[0005] In order to achieve the above purpose, the utility model is realized by the following technical solutions: A clamping and fastening device for polyethylene pipe fitting processing includes a device body. The device body includes a base. A chute is opened on the base. A slider is movably installed inside the chute. One end of the slider is respectively welded with a fixed seat and a support seat. A lifting mechanism is fixedly installed on the fixed seat. A displacement mechanism is fixedly installed on the support seat. One ends of the lifting mechanism and the displacement mechanism are both fixed with arc seats. A workpiece is movably installed between the arc seats.

[0006] Furthermore, a limiting groove is opened on the inner wall of the chute. A limiting block is welded at one end of the slider. The limiting block is movably installed inside the limiting groove.

[0007] Further, fixing grooves are formed in the arc-shaped seats, and fixing rods are movably installed inside the fixing grooves.

[0008] Further, threaded holes are formed at the tops of the support seats, fixing bolts are rotatably installed on the fixing seats, and one ends of the fixing bolts are rotatably installed inside the threaded holes.

[0009] Further, friction plates are fixed on the inner walls of the arc-shaped seats, and the friction plates are in contact with the outer walls of the workpieces.

[0010] Further, movable columns are installed on both the displacement mechanism and the lifting mechanism, and one ends of the movable columns are fixed on the arc-shaped seats.

[0012] 1. For this clamping and fastening device for polyethylene pipe fittings processing, when in use, the support seat and the fixing seat are distributed in a front-back dislocation manner. The pipe fittings are placed on the arc-shaped seat for multi-point support clamping. After clamping, the support area of the pipe fittings is increased to complete horizontal support for longer pipe fittings.

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0020] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a clamping and fastening device for polyethylene pipe fitting processing, including a device body. The device body includes a base 1, a sliding groove 2 is opened on the base 1, a sliding block 3 is movably installed inside the sliding groove 2, one ends of the sliding block 3 are respectively welded with a fixed seat 4 and a support seat 5, a lifting mechanism 10 is fixedly installed on the fixed seat 4, a displacement mechanism 6 is fixedly installed on the support seat 5, arc seats 7 are fixed at one ends of the lifting mechanism 10 and the displacement mechanism 6, a workpiece 14 is movably installed between the arc seats 7, a limiting groove is opened on the inner wall of the sliding groove 2, a limiting block 13 is welded at one end of the sliding block 3, and the limiting block 13 is movably installed inside the limiting groove. The lifting mechanism 10 and the displacement mechanism 6 are both electric push rods, and the electric push rods push the arc seats 7 to approach each other. After the arc seats 7 approach each other, the clamping and fixing of the workpiece 14 are completed.

[0021] In this embodiment, fixing grooves 11 are opened on the arc seats 7, fixing rods 12 are movably installed inside the fixing grooves 11, threaded holes 8 are opened on the top of the support seat 5, fixing bolts 9 are rotatably installed on the fixed seat 4, one ends of the fixing bolts 9 are rotatably installed inside the threaded holes 8, friction plates are fixed on the inner walls of the arc seats 7, and the friction plates are in contact with the outer walls of the workpiece 14. Moving columns are installed on both the displacement mechanism 6 and the lifting mechanism 10, and one ends of the moving columns are fixed on the arc seats 7. The friction plates realize buffer protection for the workpiece 14 to avoid collision damage to the workpiece 14 caused by the arc seats 7.

[0022] The device provides the required electrical energy for the electrical appliances inside the device through an external power supply. When using the device, first adjust the fixed seat 4 and the support seat 5 according to the length and clamping method of the workpiece 14. When it is necessary to clamp and fix one end of the workpiece 14, place one end of the workpiece 14 between the arc seats 7. At the same time, start the displacement mechanism 6 and the lifting mechanism 10 to push the arc seats 7 to move closer inward. The inward movement of the arc seats 7 completes the clamping and fixing of one end of the workpiece 14. When it is necessary to achieve multi-point support clamping of the workpiece 14, remove the fixing bolt 9 from the fixed seat 4. After the fixing bolt 9 is removed, the support seat 5 is separated from the fixed seat 4. After separation, move the fixed seat 4 and the support seat 5 inside the chute 2 respectively, and distribute the fixed seat 4 and the support seat 5 at three positions. Place the workpiece 14 between the support seat 5 and the fixed seat 4, and start the displacement mechanism 6 and the lifting mechanism 10. The displacement mechanism 6 and the lifting mechanism 10 push the arc seats 7 to contact and support the workpiece 14 at different positions, and complete the clamping and fixing of the workpiece 14 while supporting. During the clamping and fixing, the arc seat 7 pushes the support seat 5 or the fixed seat 4 to generate a reaction force, and the reaction force squeezes and rubs the slider 3 and the limit block 13 against the chute 2 to limit and fix the fixed seat 4 and the support seat 5. In addition, when the fixed seat 4 and the support seat 5 are matched, after installing the fixed rod 12 inside the fixed groove 11, install the fixed rod 12 inside the workpiece 14, and expand the fixed rod 12 from the inside of the pipe fitting to complete the clamping and support of the workpiece 14 from the inside, which is convenient for realizing the processing and use of the surface of the pipe fitting.
