Description

Technical Field

[0001] This utility model relates to the field of cutting and positioning technology, specifically a cutting and positioning device for CPVC cable protection pipes. Background Technology

[0002] CPVC cable protection pipe is a high-performance cable protection sleeve made of chlorinated polyvinyl chloride (CPVC). It can protect cables from external mechanical damage, chemical corrosion and high temperature effects, and ensure the safe and stable operation of cables.

[0003] The CPVC cable protection pipe cutting and positioning device is a tool used to accurately position CPVC cable protection pipes when cutting them. In cable laying and other projects, the protection pipes need to be cut to a suitable length. This device, through a specific structure or design, can quickly and accurately fix the protection pipes at the predetermined cutting position.

[0004] However, when the cutting and positioning device clamps and positions the CPVC cable protection pipe, the cutting debris generated is very easy to fly and adhere to the positioning fixture. If these debris are not cleaned in time, they will cause the pipe to shift or tilt during the subsequent pipe positioning process. Once the pipe positioning is inaccurate, it will directly cause problems such as cutting length error and skewed cut, affecting the processing quality and subsequent performance of the CPVC cable protection pipe. At present, the common solution is to set up a fan on the workbench to accelerate the falling of debris using airflow. However, due to the complex structure of the cutting and positioning device, there are many components that block the flow, especially the debris located at the top of the cutting and positioning device, which is difficult to be effectively cleaned by the airflow generated by the fan. Therefore, a cutting and positioning device for CPVC cable protection pipe is proposed to address the above problems. Utility Model Content

The airflow is used to accelerate the falling of debris, but due to the complex structure of the cutting and positioning device, there are many parts that block the flow, especially the debris located at the top of the cutting and positioning device, which is difficult to be effectively cleaned by the airflow generated by the fan.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

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.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Please see Figures 1-7 This utility model provides a technical solution:

[0032] A cutting and positioning device for CPVC cable protection pipe includes a base 1, a support platform 2 fixedly connected to the top of the base 1, a positioning component 3 fixedly connected to the top of the support platform 2, an angle measuring platform 4 fixedly connected to the front end of the support platform 2, and a cutting table 5 rotatably connected above the angle measuring platform 4. The positioning component 3 includes a base 31, a right V-shaped positioning clamp 32 fixedly connected to the inner side of the base 31, a mounting post 33 fixedly connected to one end of the inner side of the right V-shaped positioning clamp 32 by bolts, a screw 34 threadedly connected to the middle of the inner side of the mounting post 33, an adjusting frame 35 rotatably connected to the middle of the outer wall of the screw 34, a toothed rod 36 fixedly connected to the top of the adjusting frame 35, and a left V-shaped positioning clamp 37 fixedly connected to one end of the toothed rod 36 via a mounting base. A transmission mechanism 38 is fixedly connected to the top of the positioning clamp 37, and a transmission assembly 39 is fixedly connected to the top of the inner side of the right V-shaped positioning clamp 32. The transmission assembly 39 includes a connecting shaft 391, a gear 392 is rotatably connected to the outer side of the connecting shaft 391, hexagonal tubes 393 are fixedly connected to both ends of the gear 392, a toothed tooth 394 is fixedly connected to one end of the hexagonal tube 393, a bearing seat 395 is fixedly connected to the inner wall of the right V-shaped positioning clamp 32, a connecting sleeve 396 is rotatably connected to the outer side of the bearing seat 395, a swing rod 397 is fixedly connected to one side of the connecting sleeve 396, a striking element 398 is fixedly connected to the other side of the connecting sleeve 396, and a receiving plate 399 is fixedly connected to the top of the inner wall of the right V-shaped positioning clamp 32. The gear 392 is meshed with the rack 36.

[0033] As a further implementation of this solution, the transfer mechanism 38 includes a transfer plate 381, with a connector 382 fixedly connected to the top of the transfer plate 381. Multiple connectors 382 are provided, and a C-shaped part 383 made of metal material is fixedly connected to the top of the connector 382. The C-shaped part 383 has good elasticity. The outer side of the C-shaped part 383 rotates and engages with the outer side of the hexagonal tube 393. This design enables the simultaneous cleaning of debris above the left V-shaped positioning clamp 37 during the adjustment of the positioning and clamping of the CPVC cable protection pipe, thus avoiding debris accumulation that affects the clamping accuracy and the surface quality of the pipe.

[0034] As a further implementation of this solution, the bottom of the adjusting frame 35 is slidably connected to the bottom of the inner side of the mounting column 33, and the outer side of the toothed rod 36 is slidably connected to the top of the inner side of the mounting column 33. The toothed rod 36 and the screw 34 are parallel to each other, so that the rotation of the screw 34 can be efficiently converted into the linear movement of the toothed rod 36, ensuring the accuracy and stability of the movement of the left V-shaped positioning fixture 37.

[0035] As a further implementation of this solution, gear 392 is located below rack 36. Gear 392 and hexagonal tube 393 are on the same central axis and connected. Hexagonal tube 393 and serrated tooth 394 are on the same central axis and connected. Hexagonal tube 393 and serrated tooth 394 are rotatably connected to connecting shaft 391. The position of receiving plate 399 is parallel to the position of right V-shaped positioning clamp 32. The shape of striking part 398 is "Y". There is a gap between striking part 398 and receiving plate 399, providing space for the movement of striking part 398. This design allows striking part 398 to accurately strike receiving plate 399 during swinging, generating sufficient vibration to effectively clean debris above right V-shaped positioning clamp 32.

[0036] As a further implementation of this solution, the bearing seat 395 and the connecting shaft 391 are located on the same horizontal line, there is a gap between the bearing seat 395 and the receiving plate 399, the bearing seat 395 and the connecting sleeve 396 are located on the same central axis, the front end of the swing rod 397 has an arc-shaped structure, and the front end of the swing rod 397 slides in contact with the tooth 394, which can convert the rotation of the tooth 394 into the left and right rotation of the connecting sleeve 396, thereby driving the striking part 398 to strike the receiving plate 399, realizing the function of cleaning the debris above the right V-shaped positioning fixture 32. The entire structure is compact and has high transmission efficiency, ensuring the normal operation of the cutting positioning device and the debris cleaning effect.

[0037] Work process: The base 1 of the CPVC cable protection pipe cutting and positioning device is fixedly connected to the top of the support platform 2, and the top of the support platform 2 is fixedly connected to the positioning component 3. When the CPVC cable protection pipe needs to be cut and positioned, first operate the screw 34 which is threaded to the middle of the inner side of the mounting column 33. Due to the threaded connection between the screw 34 and the mounting column 33, when the screw 34 is rotated, the adjusting frame 35 will slide at the bottom of the inner side of the mounting column 33, and at the same time drive the toothed rod 36 fixedly connected to the top and the left V-shaped positioning clamp 37 to move synchronously.

[0038] As the adjusting frame 35 moves the toothed rod 36 and the left V-shaped positioning clamp 37, the left V-shaped positioning clamp 37 gradually moves closer to the fixed right V-shaped positioning clamp 32 until the CPVC cable protection pipe is clamped and positioned, and the pipe is stably fixed in the cutting position.

[0039] During the adjustment of the adjusting frame 35, the rack 36 meshes with the gear 392 in the transmission assembly 39 located below it. As the rack 36 moves, it drives the gear 392 to rotate. Since the two ends of the gear 392 are fixedly connected to the hexagonal tube 393, and one end of the hexagonal tube 393 is fixedly connected to the spline tooth 394, the gear 392, the hexagonal tube 393, and the spline tooth 394 will rotate synchronously. During the rotation of the hexagonal tube 393, its outer side contacts the C-shaped part 383 of the transmission mechanism 38 above the left V-shaped positioning clamp 37. When the hexagonal tube 393 passes over multiple C-shaped parts 383, the C-shaped parts 383 will continuously undulate due to elastic deformation, thereby causing continuous vibration of themselves. This vibration is transmitted through the connecting part 382 and the transmission plate 381. The vibration is directly transmitted to the top of the left V-shaped positioning clamp 37, causing the debris attached to the top of the left V-shaped positioning clamp 37 to be shaken off. At the same time, during the rotation of the toothed 394, the front end of the swing rod 397 located on one side of it will slide and contact the root and teeth of the toothed 394. This sliding causes the swing rod 397 to swing frequently left and right around the connecting sleeve 396. This swing causes the striking part 398 to strike the inner wall of the receiving plate 399. The resulting vibration is directly transmitted to the top of the right V-shaped positioning clamp 32, realizing the shaking off and cleaning of the debris above the right V-shaped positioning clamp 32. Subsequently, with the assistance of the angle measuring table 4 and the cutting table 5, the positioned CPVC cable protection pipe can be precisely cut.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
