Description

Technical Field

[0001] This utility model relates to the technical field of cable slicing machines, specifically a cable slicing machine. Background Technology

[0002] Cables are fundamental components in fields such as power transmission and signal communication. The performance of their insulation layer is directly related to the safety and reliability of the entire circuit system. During the manufacturing, quality inspection and fault analysis process, it is often necessary to conduct precise microscopic observation and analysis on the thickness, uniformity, material structure and aging degree of the insulation layer. For this reason, it is necessary to prepare high-quality insulation layer sheet samples with uniform thickness, smooth edges and no internal extrusion deformation. Currently, in laboratories and industrial settings, the slicing and sampling of cable insulation layers mainly relies on manual operation. One of the most common methods is to use a manual slicing knife or razor to directly cut the stationary cable. This method has significant inherent drawbacks: First, when cutting soft or elastic insulating materials (such as PVC, polyethylene, rubber, etc.), the unidirectional pressure applied by the blade can cause severe compression, stretching, or tearing deformation of the insulation layer, making it impossible to obtain a cross-sectional morphology that reflects its true microstructure. This results in distorted observation results and affects the accuracy of analysis and judgment. Secondly, manual control relies entirely on the operator's experience and feel, making it difficult to guarantee the uniformity and consistency of the slice thickness. The thickness of each slice is highly random and has poor repeatability, which cannot meet the requirements of quantitative analysis and precision detection. Furthermore, operating on round cables with a sharp blade poses a great safety hazard and can easily injure the operator. To partially improve slice quality, some slicing devices with simple clamps have emerged in the existing technology. These devices usually fix the cable with clamps, but the cutting process still requires manual advancement of the blade. However, this unidirectional and intermittent cutting method still cannot fundamentally solve the problem of sample plastic deformation caused by localized concentrated force. At the same time, for situations where multiple continuous, equal-thickness thin slices need to be prepared along the axial direction, existing equipment generally lacks a precise micro-feed mechanism, making it difficult to achieve accurate and repeatable thickness control. Operators usually rely on guesswork to estimate, resulting in low slicing efficiency and inconsistent sample quality, which seriously restricts the efficiency and accuracy of the detection work.

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a slicer that ensures flat and uniform slices.

[0004] The technical solution adopted by this utility model to achieve the above objectives is: a cable slicing machine, including a frame and an electrical box and a drive box fixedly connected to the frame. A slicing table is fixedly connected to the top of the frame, a cutting component is rotatably connected to the slicing table, and an insulation layer mold is fixedly connected to one side of the cutting component on the slicing table. The drive box is located at the bottom of the slicing stage. The drive box is equipped with a lifting adjustment module, which includes a lifting platform capable of lifting. A spline shaft is rotatably connected to the lifting platform. A spline sleeve is rotatably connected to the drive box. The spline sleeve is splinedly engaged with the spline shaft. The drive box is equipped with a drive mechanism, which is poweredly connected to the spline shaft disc. The drive box has a through-hole corresponding to the insulating layer mold. The top end of the spline shaft passes through the through-hole and is fixedly connected to a fixed shaft. The fixed shaft has an insulating layer insertion hole corresponding to the insulating layer mold. The fixed shaft has a fixing component that cooperates with the insulating layer insertion hole.

[0005] In the above technical solution, the cutting component has the following structure: The cutting component includes a rotating platform, a bevel cutting blade, a protective plate, and an operating handle. The rotating platform is rotatably connected to the slicing platform, and the bevel cutting blade is fixedly connected to the rotating platform. The protective plate is fixedly connected to the rotating platform above the bevel cutting blade. The bottom surface of the bevel cutting blade is flush with the top surface of the insulating layer mold, and the operating handle is fixedly connected to the end of the rotating platform.

[0006] In the above technical solution, the lifting adjustment module adopts the following structure: The lifting adjustment module also includes a guide column, a lead screw, and a power input component. The guide column is fixedly connected inside the drive box, and the lifting platform is slidably connected to the guide column. A lead screw sleeve is fixedly connected to the lifting platform, and the lead screw is threaded onto the lead screw sleeve. The power input component is provided on the drive box and is poweredly connected to the lead screw.

[0007] In one embodiment, the power input component has the following structure: The power input component includes an input shaft, a worm gear, a worm wheel, a first bevel gear, a second bevel gear, and an operating handle. The input shaft is fixedly connected to the top of the lead screw, and the worm wheel is fixedly connected to the input shaft. The worm gear is rotatably connected inside the drive housing, and the worm gear meshes with the worm wheel. One end of the worm gear is fixedly connected to the first bevel gear. The operating handle is rotatably connected to the drive housing, and the bottom end of the operating handle is located inside the drive housing and fixedly connected to the second bevel gear. The first bevel gear meshes with the second bevel gear.

[0008] In the above technical solution, the spline shaft includes a shaft body and a spline strip fixedly connected to the outer wall of the shaft body; The spline sleeve includes a sleeve plate and a rotating ring fixedly connected to the bottom of the sleeve plate. The sleeve plate has a shaft hole and a spline groove communicating with the shaft hole. The shaft passes through the shaft hole and the spline bar cooperates with the spline groove. A connecting platform is fixedly connected inside the drive box, and the rotating ring is rotatably connected to the connecting platform.

[0009] In the above technical solution, the driving mechanism is specifically as follows: The drive mechanism includes a drive motor, a power output shaft, a gear ring, and a gear.

[0010] In the above technical solution, the fixing component adopts the following structure: The fixing component includes a bolt, an abutment head, and an operating knob. The bolt is threaded onto the fixing shaft, the abutment head is fixedly connected to the inner end of the bolt, and the operating knob is fixedly connected to the outer end of the bolt.

[0011] The beneficial effects of this utility model are: 1. The insulating layer is cut by a beveled blade while rotating, so that the blade acts on every point on the sample circumference instantaneously, which greatly reduces the squeezing, tearing or deformation caused by traditional one-cutting. It can obtain slices with smooth edges and complete structure. In addition, the lifting adjustment module allows for tiny feeds of the insulating layer. The operator can first cut the sample flat (cut off the protruding part), and then lift it only a tiny distance each time to cut a slice with uniform thickness. This solves the problem of uneven slice thickness and poor precision when manually controlling the slice. 2. The drive motor is directly fixed inside the drive box, rather than fixed to the lifting platform. This greatly reduces the weight of the lifting platform, making it easier to raise the platform and improving the accuracy and response speed of the lifting platform's movement.

The electrical box 200 has a motor controller installed inside, and a power switch 201 and a speed adjustment knob 202 are provided on its outer surface. The slicing table 400 is fixedly connected to the top of the frame 100 and is used to support the slicing operation. The drive box 300 is located below the slicing table 400. The cutting blade assembly 500 is rotatably connected to the slicing stage 400. Specifically, the cutting blade assembly 500 includes a rotating stage 501, a bevel cutting blade 502, a protective plate 503, and an operating handle 504. The rotating stage 501 is rotatably connected to the slicing stage 400 via a rotating shaft. The bevel cutting blade 502 is fixedly mounted on the rotating stage 501. The protective plate 503 is fixedly connected to the rotating stage 501 and is located above the bevel cutting blade 502 to isolate the bevel cutting blade 502 and ensure safety. The operating handle 504 is fixedly connected to the end of the rotating stage 501 to facilitate the operator to apply force to rotate it. The insulation layer mold 600 is fixedly connected to the slicing table 400 and located on one side of the cutter component 500. The insulation layer mold 600 has a mold hole 601, through which the insulation layer of the cable to be cut can pass. The bottom surface of the oblique cutter 502 is at the same level as the top surface of the insulation layer mold 600, thus forming a precise cutting reference surface. The drive box 300 is equipped with a lifting adjustment module 700, which includes a guide column 701, a lead screw 702, a power input component 703, and a lifting platform 704.

A shaft hole 2003 is provided in the center of the sleeve plate 2001, and a spline groove 2004 that mates with the spline bar 1002 is provided in communication with the shaft hole 2003. The shaft body 1001 of the spline shaft 1000 passes through the shaft hole 2003, and the spline bar 1002 on it forms a spline engagement with the spline groove 2004. This structure allows the spline shaft 1000 to be lifted and lowered as a whole with the lifting platform 704, and to be continuously rotated by the spline sleeve 2000. A through-hole is provided on the top of the drive box 300 corresponding to the position of the insulating layer mold 600. The top end of the spline shaft 1000 extends upward through the through-hole and is fixedly connected to a fixed shaft 3000. An insulating layer insertion hole 3001 is provided in the center of the fixed shaft 3000 to accommodate the end of the cable passing through the mold hole 601. A fixing component 900 for clamping the cable is also provided on the fixed shaft 3000. Preferably, the fixing component 900 includes a bolt 901, a contact head, and an operating knob 902. The bolt 901 is threadedly connected to the fixing shaft 3000. Its inner end is fixed with a soft contact head that can prevent damage to the cable, and its outer end is fixed with an operating knob 902 that is easy to operate by hand. The drive mechanism 800 is disposed inside the drive housing 300 and is used to provide rotational power for the spline sleeve 2000. Specifically, the drive mechanism 800 includes a drive motor 801, a power output shaft 802, a gear ring 803, and a gear 804. The gear ring 803 is fixedly sleeved on the outer periphery of the sleeve disc 2001 of the spline sleeve 2000. The drive motor 801 is fixedly installed inside the drive housing 300. The power output shaft 802 is poweredly connected to the output end of the drive motor 801 (e.g., through a coupling or belt drive) and is rotatably supported inside the drive housing 300. The gear 804 is fixedly installed on the power output shaft 802 and meshes with the gear ring 803. Furthermore, the drive motor 801 is electrically connected to the motor controller inside the electrical box 200, and the operator can control the start, stop and speed of the motor through the power switch 201 and speed control knob 202 on the electrical box 200.

[0016] The working process of this invention is as follows: First, the insulation layer of the cable to be cut is passed through the mold hole 601 of the insulation layer mold 600 in sequence, and its end is inserted into the insulation layer insertion hole 3001 on the fixed shaft 3000. The operating knob 902 of the fixing component 900 is rotated, and the contact head is pushed by the bolt 901 to press the cable, thus completing the fixing. Then, turn on the power switch 201, adjust the speed control knob 202 to the appropriate speed, start the drive motor 801, drive the gear ring 803 and spline sleeve 2000 to rotate through the gear 804 on the power output shaft 802, and then transmit the power to the spline shaft 1000 and the fixed shaft 3000 through the spline engagement, so that the fixed cable rotates at a constant speed. At this time, the operator holds the operating handle 504 and slowly rotates the rotating table 501, so that the oblique cutting blade 502 gradually approaches and finally cuts off the section of cable insulation layer that protrudes from the top surface of the insulation layer mold 600, thus completing the end face leveling. After leveling, stop the drive motor 801, turn the operating handle 7036, and rotate the drive screw 702 to make the lifting platform 704 drive the spline shaft 1000, the fixed shaft 3000 and the cable to rise synchronously and precisely by a small distance (e.g., the required slice thickness). Restart the drive motor 801 to rotate the cable and manipulate the cutter component 500 to cut, and you can obtain a thin insulating layer sample with uniform thickness and a flat, undeformed surface. By repeating the "lift-cut" steps, you can efficiently and continuously prepare multiple high-quality experimental samples.
