Description

Technical Field

[0001] This utility model relates to the field of PE pipe processing technology, and in particular to a clamping device for PE pipe processing. Background Technology

[0002] PE is polyethylene plastic, the most basic type of plastic. Plastic bags, cling film, etc. are all made of PE. HDPE is a highly crystalline, non-polar thermoplastic resin.

[0003] During the production and processing of PE pipes, clamping fixtures are used to clamp the outer wall of the PE pipe. Currently, the clamps use two arc-shaped clamping plates to clamp the PE pipe, and then connect the two clamping plates with bolts. This clamping method not only increases the workload of the operator, but the specifications of the clamping plates cannot clamp PE pipes of different specifications. After the PE pipe is limited, the processing surface cannot be adjusted, which in turn reduces the efficiency of subsequent processing of PE pipes. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the processing surface of PE pipe cannot be adjusted after the PE pipe is limited in the prior art, and to propose a clamping device for PE pipe processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A clamping device for PE pipe processing includes an integrally connected platform and a vertical plate. A symmetrically arranged sleeve is rotatably mounted on the vertical plate, and a controller and a guide rod are fixedly installed inside the sleeve. Four circumferentially distributed connecting rods are movably mounted on the guide rods. A slider is slidably sleeved on the guide rods, and a pressure rod is connected between the slider and the connecting rod. An abutment plate is provided on the connecting rod to move against the inner wall of the PE pipe. A rotating structure for driving the sleeve to rotate is provided on the processing strip.

[0006] Preferably, the sleeve is horizontally positioned on both sides of the upright plate, and the end of the connecting rod away from the contact plate is connected to the guide rod pin.

[0007] Preferably, a telescopic rod connected to the slider is fixedly installed inside the sleeve, and the two ends of the pressure rod are respectively connected to the slider and the middle pin of the connecting rod.

[0008] Preferably, the contact plate is disposed at one end of the connecting rod extending outside the sleeve, and the contact plate is an arc-shaped structure adapted to the inner wall of the PE pipe, and the sleeve is provided with an elongated hole for guiding the connecting rod.

[0009] Preferably, the rotating structure includes a sealing cover fixedly installed on the upright plate, and a motor electrically connected to the controller is fixedly installed inside the sealing cover, and a rotating shaft connected to the sleeve drive is fixedly connected to the output end of the motor.

[0010] Preferably, a ring-shaped rack is fixedly installed on the sleeve, the rotating shaft is horizontally positioned below the sleeve, and a gear that meshes with the ring-shaped rack is fixedly installed on the rotating shaft.

[0011] Compared with the prior art, the present invention has the following advantages: 1. This utility model provides a circumferentially distributed contact plate on the sleeve. After the contact plate is unfolded, it moves against the inner wall of the PE pipe, thereby limiting the PE pipe. Furthermore, the contact plate can clamp PE pipes of different specifications when the slider moves.

[0012] 2. This utility model provides a ring-shaped rack on the sleeve and rotates the sleeve by rotating the shaft. When the sleeve rotates, it adjusts the processing surface of the PE pipe, making the adjustment of the PE pipe more convenient. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3 A clamping device for PE pipe processing includes an integrally connected platform 1 and a vertical plate 2. A symmetrically arranged sleeve 3 is rotatably mounted on the vertical plate 2, and a controller and a guide rod 4 are fixedly installed inside the sleeve 3. Four circumferentially distributed connecting rods 6 are movably mounted on the guide rod 4.

[0017] A slider 5 is slidably mounted on the guide rod 4, and a pressure rod 7 is connected between the slider 5 and the connecting rod 6. A telescopic rod connected to the slider 5 is fixedly installed inside the sleeve 3. The two ends of the pressure rod 7 are respectively connected to the middle pin of the slider 5 and the connecting rod 6. The guide rod 4 guides the slider 5 so that the slider 5 can drive the connecting rod 6 to move smoothly when it moves.

[0018] The connecting rod 6 is provided with a contact plate 8 that moves against the inner wall of the PE pipe. The sleeve 3 is horizontally positioned on both sides of the vertical plate 2. The end of the connecting rod 6 away from the contact plate 8 is connected to the guide rod 4 by a pin. The contact plate 8 is located at the end of the connecting rod 6 that extends outside the sleeve 3, and the contact plate 8 is an arc-shaped structure adapted to the inner wall of the PE pipe. When the slider 5 moves, it applies pressure to the connecting rod 6 through the pressure rod 7, causing the connecting rod 6 to drive the contact plate 8 to move against the inner wall of the PE pipe, thereby limiting the PE pipes of different specifications. The sleeve 3 is provided with an elongated hole for guiding the connecting rod 6. By setting the contact plate 8 as an arc-shaped structure adapted to the inner wall of the PE pipe, the contact area between the contact plate 8 and the PE pipe can be increased.

[0019] The processing strip is equipped with a rotating structure for driving the sleeve 3 to rotate.

[0020] The rotating structure includes a sealing cover 9 fixedly installed on the vertical plate 2, and a motor electrically connected to the controller is fixedly installed inside the sealing cover 9. The sealing cover 9 can seal the ring rack 11 and the gear 12. The output end of the motor is fixedly connected to a rotating shaft 10 that is connected to the sleeve 3 for transmission. The ring rack 11 is fixedly installed on the sleeve 3. The rotating shaft 10 is horizontally positioned below the sleeve 3. The gear 12 that meshes with the ring rack 11 is fixedly installed on the rotating shaft 10. When the rotating shaft 10 rotates, it drives the sleeve 3 to rotate through the ring rack 11 and the gear 12. When the sleeve 3 rotates, it drives the contact plate 8 and the PE pipe to rotate. When the PE pipe rotates, it can adjust the processing surface.

[0021] The functional principle of this utility model can be explained through the following operation methods: Extend one end of the PE pipe to the sleeve 3 so that the sleeve 3 and the contact plate 8 can move into the inner wall of the PE pipe; The controller sends a signal to the telescopic rod, and the telescopic rod output end extends and retracts, causing the slider 5 to slide on the guide rod 4. When the slider 5 moves, it pulls the pressure rod 7. When the pressure rod 7 moves, it applies pressure to the connecting rod 6, causing the connecting rod 6 to deflect around the pin point. When the connecting rod 6 deflects in the long hole, it causes the contact plate 8 to move and abut against the inner wall of the PE pipe, thereby limiting the PE pipe. When it is necessary to adjust the processing surface of the PE pipe, the controller sends an start signal to the motor. The motor output drives the rotating shaft 10 to rotate. When the rotating shaft 10 rotates, it drives the sleeve 3 to rotate through the meshing gear 12 and the ring rack 11. When the sleeve 3 rotates in the vertical plate 2, it adjusts the processing surface of the PE pipe.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
