Description

Technical Field

[0001] This utility model relates to the field of internal clamping of pipes to be processed, specifically a fixing device for cutting resin pipes during production. Background Technology

[0002] The main reasons why epoxy resin pipes need to be cut are as follows: To meet size requirements: In practical applications, epoxy resin pipes usually need to be customized in length and diameter according to specific engineering designs or usage scenarios. For example, in electrical equipment, epoxy resin pipes, which are used as insulating components, need to be precisely cut to a specific length to fit the equipment space.

[0003] In existing technologies, cutting devices are generally used for cutting. During the high-speed rotation of the blade part of the cutting device, the cutting thickness is controlled by controlling the feed amount of the blade (the actuator is generally a motor and lead screw structure, and the feed amount is controlled and fed back through a program and encoder).

[0004] During the cutting process, the polyurethane tube needs to be fixed to prevent it from shaking. Existing fixing devices are not suitable for various types of polyurethane tubes, and they are not convenient to drive the polyurethane tube to rotate after fixing. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3In this embodiment of the present invention, a fixing device for cutting resin tubes includes a fixing tube 1. The fixing tube 1 has multiple sets of guide groove structures inside. Each set of guide groove structures includes four square grooves. An inner clamping block 2 is slidably connected to the inner wall of the square groove. The inner clamping block 2 passes through the square groove and extends to the outer wall of the fixing tube 1. A pushing mechanism extending to the outside of one end of the fixing tube 1 is installed on the inner wall of the fixing tube 1. A rotating mechanism is installed at one end of the outer wall of the fixing tube 1.

[0019] In this embodiment: First, the polyurethane tube to be cut is fitted onto the outer wall of the fixed tube 1. Then, the pushing mechanism is activated. During the movement, the pushing mechanism pushes the inner clamping block 2 to slide along the square groove. The four inner clamping blocks 2 in a group move outward synchronously until the inner clamping block 2 effectively clamps the inner wall of the polyurethane tube. At this time, the polyurethane tube is effectively fixed. During cutting, the rotating mechanism is activated, which drives the fixed tube 1 to rotate. When the fixed tube 1 rotates, it drives the polyurethane tube to rotate through the inner clamping block 2. Therefore, during the cutting process, the cutting device only needs to control the cutting feed rate and does not need to rotate.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The pushing mechanism includes an electric push cylinder 4 located at one end of the outside of the fixed tube 1. The piston rod end of the electric push cylinder 4 is rotatably mounted with a connecting rod 5 via a bearing. The connecting rod 5 extends into the inner cavity of the fixed tube 1. Multiple equidistantly distributed extrusion blocks 9 are fixedly mounted on the outer wall of the connecting rod 5.

[0021] In this embodiment: by activating the electric push cylinder 4, the electric push cylinder 4 pulls the connecting rod 5 to move axially, and the connecting rod 5 drives multiple extrusion blocks 9 to move synchronously. The extrusion blocks 9 can then extrude the inner clamping block 2, at which point the inner clamping block 2 can move outward.

[0022] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The outer wall of the extrusion block 9 is formed with extrusion slopes on all four sides. The inner clamping block 2 is formed with a pressure slope at one end near the extrusion slope. The extrusion slope and the pressure slope match. The inner clamping block 2 is provided with a sliding ball groove 11 at one end near the extrusion block 9. A hook ball 10 that is slidably connected to the sliding ball groove 11 is integrally formed on the extrusion slope of the extrusion block 9.

[0023] In this embodiment: during the movement of the extrusion block 9, its extrusion slope presses against the pressure-receiving slope of the inner clamping block 2, and the inner clamping block 2 moves outward under pressure, thereby clamping the inner wall of the polyurethane tube.

[0024] During the movement of the extrusion block 9, the extrusion block 9 drives the hook ball 10 to slide within the sliding ball groove 11;

[0025] It should be noted that two-thirds of the hook ball 10 is located inside the sliding ball groove 11, which can effectively prevent the inner clamping block 2 and the squeezing block 9 from falling off.

[0026] Please refer to this carefully. Figure 1 and Figure 2 The rotating mechanism includes a driven pulley 3 fixedly mounted on one end of the outer wall of the fixed tube 1. The driven pulley 3 is connected to the driving pulley 7 via a transmission belt 6. One end of the driving pulley 7 is fixedly connected to the output shaft of the rotary motor 8.

[0027] In this embodiment: when cutting the polyurethane tube, the rotary motor 8 is started, and the rotary motor 8 drives the drive pulley 7 to rotate. The drive pulley 7 drives the driven pulley 3 to rotate through the transmission belt 6. The rotating driven pulley 3 drives the fixed tube 1 to rotate. Therefore, during the cutting process, the purpose of rapid circumferential cutting can be achieved.

[0028] 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.
