Technical Field
[0001] The utility model relates to the technical field of cable protection tube processing, in particular to a positioning and cutting device for processing an MPP cable protection tube. Background Art
[0002] MPP cable protection pipes are widely used in engineering fields such as electricity and communications due to their advantages such as high strength, corrosion resistance and good insulation. In the production and processing of MPP cable protection pipes, precise cutting is an indispensable key link. The cutting accuracy directly affects the adaptability and engineering quality of subsequent installation and use.
[0003] When cutting protective tubes, existing cutting devices are prone to causing the protective tubes to shift, and cannot effectively fix protective tubes of different specifications, thereby reducing the cutting accuracy of the protective tubes.
[0004] The existing patent (Announcement No.: CN213055065U) is a cutting device for CPVC cable protective tubes. The fixed plate effectively prevents the cutting device from easily shifting the protective tube when cutting. It is conducive to fixing protective tubes of different specifications, facilitating operation, and greatly improving the cutting accuracy of the protective tube.
[0005] In response to the above problems, the existing patents have provided solutions, but the fixing structure of the above-mentioned cutting device only limits the protective tube from a single direction. During the cutting process, the protective tube may still produce slight shaking due to uneven force, affecting the flatness and dimensional accuracy of the cutting surface. In addition, during the cutting process, when the existing cutting device is cutting a longer protective tube, it is unable to provide effective auxiliary support for the cutting part. The cutting part is prone to deformation or shaking due to lack of support, further reducing the cutting quality.
[0006] Therefore, a positioning and cutting device for processing MPP cable protection tubes is proposed. Utility Model Content

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figure 1-5, this utility model provides a technical solution:
[0028] A positioning and cutting device for processing MPP cable protection tubes includes a processing table 1, a support frame 2 is provided on the rear side of the top of the processing table 1, a hydraulic cylinder 3 is fixedly connected to the top of the support frame 2, a drive box 4 is fixedly connected to the telescopic end of the hydraulic cylinder 3, and a cutting knife 5 is fixedly connected to the output end of the drive box 4. An auxiliary support assembly 6 is provided on the front side of the support frame 2, and an adjustment assembly 7 is provided inside the auxiliary support assembly 6. The adjustment assembly 7 includes a bidirectional screw 701;
[0029] The auxiliary support assembly 6 includes a movable seat 601, the rear side of the movable seat 601 is fixedly connected to a linkage block 602 and the side of the linkage block 602 close to the support frame 2 is fixedly connected to the support frame 2, the top of the movable seat 601 is provided with an arc plate 603 and the interior of the arc plate 603 is provided with a protective tube body 8, the number of arc plates 603 is set to two and the two arc plates 603 are used in conjunction with the cutting knife 5.
[0030] In this embodiment: by setting up an auxiliary support assembly 6, the movable seat 601 serves as the main frame of the auxiliary support assembly 6, which can be used to install the arc plate 603, and is fixed to the support frame 2 through the linkage block 602, so that the entire auxiliary support assembly 6 forms a rigid connection with the support seat, and the arc plate 603 can position and support the protective tube body 8, forming stable support points on both sides of the protective tube body 8 to prevent the protective tube body 8 from being deformed or offset due to uneven force during cutting, thereby ensuring cutting accuracy.
[0031] Specifically, such as Figure 3 As shown, mounting grooves 9 are provided on the front and rear sides of the movable base 601 , and both ends of the bidirectional screw 701 are rotatably connected to the inside of the mounting grooves 9 through bearings.
[0032] Specifically, such as Figure 4 As shown, both sides of the surface of the bidirectional screw 701 are threadedly connected with threaded blocks 702, and the threaded blocks 702 are slidably connected to the inside of the mounting groove 9. The outer side of the threaded block 702 is fixedly connected with a connecting rod 703, and the side of the connecting rod 703 close to the arc plate 603 is fixedly connected to the arc plate 603.
[0033] Specifically, such as Figure 4 As shown, a micro motor 704 is fixedly connected to the right side of the moving base 601 , and the output end of the micro motor 704 passes through the moving base 601 and is fixedly connected to the right end of the bidirectional screw 701 .
[0034] In this embodiment: through the above settings, the mounting groove 9 can provide installation space for components such as the bidirectional screw 701 and the threaded block 702, ensuring that the bidirectional screw 701 can rotate stably. When the bidirectional screw 701 rotates, the rotational motion can be converted into the linear motion of the threaded block 702 through thread transmission. When the threaded block 702 moves, it will drive the connecting rod 703 and the arc plate 603 to move together, so that the spacing between the two arc plates 603 can be adjusted according to usage requirements, thereby improving the support effect on the protective tube body 8. The micro motor 704 can drive the bidirectional screw 701 to rotate, and the micro motor 704 can accurately adjust the speed and direction of the bidirectional screw 701 through an external controller, thereby realizing the automatic and stepless adjustment of the spacing between the arc plates 603, adapting to different cutting requirements, and improving the convenience of use.
[0035] Specifically, such as Figure 2 As shown, a cross moving groove 10 is opened on the rear side of the top of the processing table 1, and a cross moving block 11 is slidably connected inside the cross moving groove 10, and the top of the cross moving block 11 is fixedly connected to the bottom of the support frame 2.
[0036] Specifically, such as Figure 2 As shown, an electric telescopic rod 12 is fixedly connected to the interior of the cross moving groove 10 , and the telescopic end of the electric telescopic rod 12 is fixedly connected to the cross moving block 11 .
[0037] In this embodiment: through the above settings, the cross moving groove 10 can provide a sliding track for the cross moving block 11, limiting its movement to a straight line direction, ensuring the positioning accuracy of the support frame 2 on the horizontal plane, and the electric telescopic rod 12 can drive the support frame 2, the cutting knife 5 and the auxiliary support assembly 6 to move synchronously, so that the lateral position of the cutting knife 5 can be flexibly adjusted to meet different cutting requirements.
[0038] Specifically, such as Figure 1 As shown, side panels 13 are fixedly connected to both sides of the top of the processing table 1 and telescopic cylinders 14 are fixedly installed on the opposite sides of the two side panels 13. The telescopic ends of the telescopic cylinders 14 are fixedly connected to rubber splints 15 and the side of the rubber splint 15 close to the protective tube body 8 is tightly fitted with the protective tube body 8.
[0039] Specifically, such as Figure 5 As shown, a slide groove 16 is opened in the middle of the top of the processing table 1, and a limit rod 17 is fixedly connected inside the slide groove 16. A slider 18 is slidably connected to the surface of the limit rod 17, and the slider 18 is fixedly connected to the bottom of the moving seat 601.
[0040] In this embodiment: through the above settings, the side plates 13 can provide an installation base for the telescopic cylinder 14, ensuring that the telescopic cylinder 14 can operate stably. The telescopic cylinder 14 can drive the rubber splint 15 to move through its own telescopic movement. The rubber splint 15 can be in direct contact with both ends of the protective tube body 8. Its material is rubber, which has good elasticity and friction. When the telescopic cylinder 14 pushes the rubber splint 15 close to the end of the protective tube body 8, the rubber splint 15 can fit tightly to the end of the protective tube body 8. On the one hand, the friction is used to prevent the protective tube body 8 from being displaced during the processing. On the other hand, the elasticity of the rubber is used to avoid causing hard damage to the protective tube body 8, thereby playing a protective role. At the same time, it can be applicable to protective tube bodies 8 of different specifications and lengths, thereby improving versatility. The slide groove 16 and the limit rod 17 can provide a guide track for the movement of the slider 18, so that the moving seat 601 can only move linearly on the path specified by the slide groove 16, thereby ensuring the accuracy of the moving trajectory of the auxiliary support assembly 6, thereby ensuring the accuracy of the cutting position.
[0041] Working principle: First, place the protective tube body 8 between the two curved plates 603, and then start the telescopic cylinder 14 through the external controller, so that the telescopic cylinder 14 pushes the rubber splint 15 to move toward the end of the protective tube body 8. When the rubber splint 15 is tightly fitted with both ends of the protective tube body 8, the protective tube body 8 can be clamped and fixed to prevent displacement during cutting. Then start the electric telescopic rod 12 to drive the cross moving block 11 to slide horizontally in the cross moving groove 10, thereby adjusting the horizontal position of the support frame 2 and the cutting knife 5, so that the cutting knife 5 is aligned with the target cutting point of the protective tube body 8. When the support frame 2 moves, it will drive the moving seat 601 to move together through the linkage block 602, so that the two curved plates 603 will Located on both sides of the cutting point, it further supports the protective tube body 8. When the spacing between the two arc-shaped plates 603 needs to be adjusted, start the micro motor 704 so that its output end drives the bidirectional screw 701 to rotate. The two threaded blocks 702 will push the two arc-shaped plates 603 closer or farther away through the connecting rod 703 until the two arc-shaped plates 603 move to the appropriate position. Then the hydraulic cylinder 3 drives the drive box 4 and the cutting knife 5 to move downward, and then the drive box 4 drives the cutting knife 5 to rotate at high speed. The high-speed rotating cutting knife 5 can cut the protective tube body 8. At the same time, the two arc-shaped plates 603 can cooperate with the cutting knife 5 to support the two sides of the cutting point of the protective tube body 8 during cutting to prevent it from being deformed due to force and ensure that the cutting edge is smooth.
[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
