DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the present invention shall fall within the scope of protection of the present invention.

As shown in FIGS. 1 to 6 , a specific embodiment of the present invention is shown: As shown in FIGS. 1 to 6 , the cable armor cutting device disclosed in the present invention comprises a lifting platform 2, wherein the lifting platform 2 comprises a fixed seat 201, a slide rail, a slider 202, an adjusting hand wheel 203 and a locking screw, wherein the slide rail is arranged on one side of the fixed seat 201, and the slider 202 can be moved up and down on the slide rail by screwing the adjusting hand wheel 203, and a cutting assembly is arranged above the slider 202, wherein the cutting assembly comprises a motor 4, a battery, an output rotating shaft 5, a saw blade 6, a mounting seat 3 and a switch, wherein the output end of the motor 4 is connected to the output rotating shaft 5, and the output rotating shaft 5 is connected to the saw blade 6, and a mounting seat 3 is arranged at the bottom of the motor 4, and the mounting seat 3 is fixed above the slider 202;

A clamping assembly 1 is welded on the other side of the fixing seat 201 . The clamping assembly 1 includes a bearing 101 and an adjustable clamp 102 . The adjustable clamp 102 is sleeved on the inner side of the bearing 101 .

Preferably, as shown in Figures 4 to 6, the adjustable clamp 102 includes a clamp 104, an adjusting screw 103, a movable head 105, a movable groove 106 and a connecting rod. The clamp 104 is provided with a through hole for accommodating the cable, and a plurality of movable grooves 106 are arranged on the inner side of the through hole. Each movable groove 106 corresponds to a movable head 105, and the movable head 105 is connected to a connecting rod, which is connected to the adjusting screw 103. By screwing the adjusting screw 103, the movable head 105 is driven to move inward or outward along the movable groove 106.

The adjustable clamp is designed to clamp and fix cables of different diameters for cutting:

1. Clamp: As the main structure of the clamp, the clamp is designed with a through hole. The purpose of this through hole is to accommodate the cable. This design inserts the cable into the clamp for subsequent fixing and cutting operations; the size of the through hole can adapt to the cable with the largest diameter on site to ensure that the cable can be stably clamped;

2. Movable slots: These slots are located inside the through-holes. They are sliding tracks designed for the movable heads. Each movable slot corresponds to a movable head, ensuring that the clamp can adapt to cables of different diameters.

3. Movable heads: They are movable parts that can slide along their respective movable grooves. The design of the movable heads allows them to fit closely to the outer surface of the cable to achieve stable clamping;

4. Connecting rod: The movable head is connected to the adjusting screw through the connecting rod. The function of the connecting rod is to convert the rotational motion of the adjusting screw into the linear movement of the movable head, thereby adjusting the clamping force and size range of the clamp;

The design of the entire clamp allows it to adapt to cables of different diameters. By adjusting the adjusting screw, the movable head can move in the movable slot, thereby changing the opening size of the clamp to adapt to cables of different diameters. It is suitable for cutting cable armor. During the cutting process, the clamp can stably fix the cable to prevent it from moving or rotating, thereby ensuring the accuracy and safety of the cutting. It is suitable for cables of various diameters and greatly improves work efficiency and processing quality.

Preferably, as shown in FIG. 1 , the top of the fixing seat 201 is welded to the innermost circumference of the bearing 101 .

The top of the fixed seat is welded to the innermost circumference of the bearing. This design not only ensures that the lifting table can be accurately positioned at the position closest to the cable, but also enables the cutting assembly installed on the lifting table slider to flexibly adapt to the circular cutting of cables of different diameters.

1. Connection between fixed seat and bearing

Welding method: The top of the fixed seat 201 is firmly connected to the innermost circumference of the bearing 101 through welding. Welding provides a strong connection strength to ensure that there is no relative displacement between the fixed seat and the bearing during the operation of the lifting platform, thereby ensuring the stability and reliability of the entire system. The welding here needs to be preheated and post-processed to ensure the welding quality.

Position selection: Welding the fixing seat on the innermost circumference of the bearing can minimize the distance between the lifting platform and the cable, allowing the cutting component to contact the cable surface more accurately, improving cutting accuracy and efficiency.

2. The relative position of the lifting platform and the cable

Minimized distance: Since the fixed seat is directly welded to the innermost side of the bearing, the lifting table can maintain the shortest distance with the cable when moving up and down. This design is conducive to reducing the mechanical vibration and displacement error of the lifting table during movement, thereby improving cutting accuracy.

Flexibility: The design of the lifting table enables it to be adjusted according to the actual height of the cable, ensuring that the cutting components can always be kept in the best working position. This flexibility allows the lifting table to adapt to the cutting needs of cables of different diameters.

3. Adaptability and precision of cutting components

Circular cutting function: The cutting assembly mounted on the lifting platform slider has a circular cutting function, that is, it can cut around the circumference of the cable. This design enables the cutting assembly to handle cables of different diameters and achieve precise circular cutting operations.

Adaptability: The design of the cutting assembly takes into account the range of cable diameters. By adjusting the position of the cutting wheel, precise cutting of cables of different diameters can be achieved.

Precision control: During the cutting process, the height of the lifting table and the rotation speed of the cutting components can be precisely controlled to ensure the accuracy and consistency of the cutting.

In summary, welding the top of the fixing seat to the innermost circumference of the bearing and realizing circular cutting of different cable diameters through the cutting assembly installed on the lifting platform slider is an efficient, accurate and safe design solution. This design solution not only improves the efficiency and accuracy of cable cutting, but also reduces the difficulty and cost of operation.

Preferably, as shown in FIG. 1 , a support leg 205 is provided at a side of the bottom of the fixing seat 201 away from the sliding block 202 .

In the design of the T-type lifting platform, the support feet set at the bottom of the fixed base away from the side of the slider not only affect the stability and placement of the equipment, but also directly affect the convenience and flexibility during use.

Support function: The legs are the key components where the fixed base contacts the ground or other supporting surfaces. They are responsible for supporting the entire lifting platform firmly.

Ease of operation: In processes such as girdling that require the table to be rotated to adjust the workpiece position, the feet need to be designed to be easy to rotate by hand. This usually means that the feet should have the right shape, size and surface treatment so that the operator can easily grasp and apply enough torque to rotate the table.

Anti-slip design: To prevent accidents caused by hand slipping or foot sliding during rotation, the surface of the foot may be made of anti-slip material or specially treated (such as adding textures, grooves, etc.) to increase grip and stability.

In summary, the design of the support foot not only takes into account the supporting function of the device, but also can be used as a rotating handle of the device, thereby improving the overall practicality of the device.

Preferably, as shown in Figure 2, the fixed seat 201 is set to a T shape, a rack 204 is set on the slide rail, a gear corresponding to the rack 204 is set on the inner side of the slider 202, and the slider 202 moves up and down on the slide rail through the engagement of the gear rack, and scale lines are set on the side of the fixed seat 201.

The T-type lifting platform is used to achieve precise movement in the vertical direction. The length of the slide rail is about 150mm and the width is about 30mm:

1. Fixed seat: This is the base of the entire lifting platform system. It is designed in a T shape to provide stability and support. The stability of the fixed seat is crucial to the normal operation of the entire system.

2. Slide rail: The slide rail is fixed on the fixed seat and is used to guide the movement of the slider. The design of the slide rail needs to ensure that the slider can move up and down smoothly and accurately.

3. Rack: The rack is fixed on the slide rail, and the rack meshes with the gear on the slider. The vertical movement of the slider is achieved by the rotation of the gear.

4. Slider: The slider is a component that can move on the slide rail. A gear corresponding to the rack is provided on its inner side. The slider moves up and down through the meshing of the gear and the rack. The rotation of the gear causes the teeth on the rack to alternately engage with the tooth grooves of the gear, thereby driving the slider 202 to move in the vertical direction.

5. Scale lines: Scale lines are set on the side of the fixed seat. These scale lines are used to indicate the height position of the slider. By setting the scale lines, quantitative height adjustment can be performed on-site to achieve precise control.

The working principle of the whole system is: by turning the adjusting hand wheel to drive the gear in the slider to engage with the rack, the slider is driven to move up and down along the slide rail. The position of the slider can be accurately read and adjusted through the scale lines on the fixed seat to meet the requirements of different heights.

In summary, through the meshing of gears and racks, the system can achieve smooth and precise lifting and lowering actions, while the use of scale lines greatly improves the convenience and accuracy of operation.

Preferably, the saw blade 6 is a high-speed steel saw blade.

The diameter of the cutting motor is about 35mm, and the diameter of the saw blade is about 75mm. The use of high-speed steel saw blades as cutting saw blades has significant advantages. Due to its special material and heat treatment process, the cutting speed is much higher than that of ordinary saw blades, thereby improving the overall work efficiency and ensuring stability and durability during high-speed cutting.

Preferably, a locking screw is provided on the other side of the slider 202 .

A locking screw is provided on the other side of the slider, which is a common mechanical locking mechanism used to fix the slider after reaching the desired height position to prevent it from being displaced due to external force.

The locking screw is a self-locking screw that can remain fixed after being tightened to prevent the slider from sliding in the vertical direction. When the slider moves to the desired height position through the gear rack engagement, the operator can manually tighten the locking screw to fix the position of the slider. If the height of the slider needs to be adjusted, the operator can manually loosen the locking screw so that the slider can move along the slide rail again. After adjusting to the new height, tighten the locking screw again to fix the slider.

The use of locking screws improves the safety and stability of the entire lifting platform system, ensuring that the slider will not slide accidentally during operation, protecting the safety of the equipment and the operator.

In summary, locking screws are an important component of the T-type lifting table system. They improve the practicality and safety of the entire system by providing a reliable fixing mechanism to ensure that the slider can stably maintain its position after reaching the required height.

Preferably, the battery is a rechargeable battery.

The choice of rechargeable batteries has many conveniences for devices that require circular cutting and rotation, especially avoiding the trouble of finding an external power source on site and the inconvenience and entanglement of wired charging.

1. Avoid the trouble of looking for an external power source on site

Increased flexibility: With rechargeable batteries, the device can be moved and operated freely in places without external power outlets, and is no longer limited by the length and location of power cords. This is especially important for devices that require circular rotation, which may need to be operated in different positions or angles.

Increased independence: With a built-in rechargeable battery, the device can operate without relying on an external power source, which increases the independence and autonomy of the device. This feature is particularly important in emergency situations or environments without external power sources.

2. Avoid the inconvenience and entanglement of wires

Convenience of operation: Wired charging requires the device to remain connected to the power cord, which not only limits the range of movement of the device, but may also affect the operating efficiency due to the entanglement of the power cord. Rechargeable batteries do not need to worry about these problems, and the device can be moved and rotated more flexibly, which improves the convenience of operation.

Improved safety: The power cord is prone to entanglement, pulling or even breaking when the device is moving or rotating, which may cause safety hazards such as short circuit and electric shock. The use of rechargeable batteries eliminates these potential safety risks and improves the safety of the device.

3. Advantages of rechargeable batteries

Environmental protection and energy saving: Rechargeable batteries can be used repeatedly, reducing the generation of battery waste and benefiting the environment. At the same time, compared with disposable batteries, rechargeable batteries have lower cost-effectiveness in long-term use.

High performance: Modern rechargeable battery technology continues to advance. For example, lithium-ion batteries have the advantages of high energy density, long cycle life, and low self-discharge rate, which can meet the high requirements of the device for battery performance.

Simple maintenance: Rechargeable batteries are relatively simple to maintain, requiring only regular charging and checking of battery status.

In summary, the choice of rechargeable batteries has significant advantages for devices that require circular cutting and rotation. It not only avoids the trouble of finding an external power source on site and the inconvenience and entanglement of wired charging, but also improves the flexibility, independence and safety of the device.

Preferably, as shown in FIGS. 1 and 4 , the adjustable clamp 102 is bonded to the inner surface of the bearing 101 .

The adjustable clamp is used to fix the cable during the circumcision process, wherein the adjustable clamp is bonded to the inner surface of the bearing; the diameter of this clamp can be adjusted to accommodate cables of different diameters. Its main function is to fix the cable during the circumcision process and ensure that the cable remains stable during the rotation of the device.

The bearing is a key component in the device, used to support the rotational motion. The inner surface of the bearing is used to bond the adjustable clamp to fix the cable. The clamp is fixed to the inner surface of the bearing by an adhesive with sufficient bonding strength and durability to withstand the forces that may be generated during the rotation process.

The diameter of the bearing is 160mm. This size is chosen to meet the needs of cables of different diameters on site. A larger bearing can provide a larger inner hole diameter to facilitate bonding of adjustable clamps with larger inner hole diameters, thereby meeting the clamping requirements of cables of different diameters.

During the circumcision process, the device needs to rotate while the cable needs to remain fixed, which means that the clamp must be able to firmly clamp the cable, and the bearing must be able to rotate smoothly to accommodate the movement of the circumcision knife, achieving a stable clamp on the cable during the circumcision process while allowing the device to perform the necessary rotational movement.

The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the field without departing from the purpose of the present invention.
