Description

Technical Field

[0001] The utility model relates to the technical field of article cutting, and more specifically, to a cable cover cutting device. Background Art

[0002] With the development of modern machining industry, the requirements for the quality and precision of cutting are continuously increasing, and the requirements for improving production efficiency, reducing production costs, and having highly intelligent automatic cutting functions are also rising; the development of numerical control cutting machines must meet the requirements of the development of modern machining industry. Cutting machines are divided into flame cutting machines, plasma cutting machines, laser cutting machines, water cutting machines, etc.; for the existing cable cover cutting devices, since the cable covers have good flexibility and are easy to bend, the cutting position is extremely likely to change when cutting the cable covers, resulting in a decline in cutting quality. At the same time, after cutting, the cable cover waste residues cut off will adhere to the cutting slices. If directly wiped with fingers, it is very likely to scratch the fingers, which is very unsafe.

[0003] Regarding the above problems, for the technical problems such as the extremely easy change of the cutting position when the existing cable cover cutting device cuts the cable cover, after a large number of retrievals, a cable cover cutting device with a patent publication number of CN208305166U is found, including a base, a support plate and a cutting slice. A support plate is fixedly connected to the right side of the base, and a cutting slice is arranged above the support plate. A notch is opened above the base, and a vertical block is tightly welded above the notch. A rocker is arranged in the vertical block, and a support shaft penetrating through the front and rear ends of the vertical block is arranged in the rocker. A shell is arranged on the right side of the rocker, and a cutting slice is fixedly connected in the shell. A slide rail is opened on the surface of the cutting slice. For this cable cover cutting device, first, the cable cover is inserted into the iron ring and closely fits with the rubber ring. Then, the cutting position to be cut is determined. At the same time, the polypropylene plastic ring is pulled, and the inner ring of the polypropylene plastic ring is overlapped with the cutting position. Since the polypropylene plastic ring material has a large anti-bending ability, when the cable cover is stuck in the iron ring, even if it is bent, the polypropylene plastic ring can be bent along with the bending of the cable cover, which is very convenient for the user to find the cutting position; however, the technical solution provided by this patent has the following problems:

[0004] (1) The inner diameter of the iron ring cannot be adjusted. Once the diameter of the cable cover to be cut is too large, the iron ring cannot fix the cable cover, making it difficult to cut large-diameter cable covers.

[0005] (2) When the diameter of the cable cover to be cut is too small, the iron ring cannot fix it stably, and the inner diameter applicable when cutting the cable cover cannot be flexibly changed.

[0006] The utility model can fix cable covers with different diameters and is flexibly applicable to cutting cable covers with different diameters. Content of the Utility Model

[0017] Beneficial effects:

[0018] 1. By providing the main fixing component, the rotating shaft enables the movable clamping plate to rotate, facilitating the adjustment of the clamping angle and position. The fixed clamping plate is in the shape of an arc plate that is convex on the left and concave on the right, and the movable clamping plate is in the shape of an arc plate that is concave on the left and convex on the right. This shape design can well fit the outer shape of the cable cover, mainly fixing the cable cover from both ends. Whether it is a cable cover with a larger diameter or a smaller diameter, the tight fit can be achieved by adjusting the position of the movable clamping plate, greatly improving the fixing stability, preventing the cable cover from shaking or displacing during the cutting process, ensuring the best fixing effect. During the fixing process, precise adjustment can be made according to different situations, increasing the reliability of the fixing;

[0019] 2. By providing the auxiliary fixing component, the movable clamping plate is connected to the slide rail by bolts, and the bolts can slide up and down in the slide rail. This design enables the height of the movable clamping plate to be adjusted according to the cable covers of different diameter sizes. When facing cable covers of various diameters, the appropriate fixing position can be easily found, enhancing the fixing stability of the cable cover during cutting and improving the versatility of the device. The left fixing block and the right fixing block are respectively installed on the fixed clamping plate and the movable clamping plate, in the shape of arc plates that are wider at the top and narrower at the bottom, and can adapt to cable covers of different sizes, providing more reliable fixing for the cable cover. The fixing block made of rubber has good elasticity and flexibility, providing a buffering effect when fixing the cable cover. For a cable cover with a smaller diameter, the tension spring can be pulled to hook the fixed ring, thereby driving the movable clamping plate to rotate leftward to fix the cable cover more tightly. The drawstring plays a role of connecting and transmitting the pulling force in this process, causing the upper end inside the movable clamping plate to bend towards the inside of the fixed clamping plate to further fix the right end of the cable cover, meeting the fixing requirements of cable covers with smaller diameters. When fixing a cable cover with a larger diameter, the tension spring can be removed from the fixed ring, no longer restricting the rightward rotation of the movable clamping plate, and cooperating with the bolts, slide rail and nuts to make the movable clamping plate and the fixed clamping plate open at a larger angle to adapt to the large-diameter cable cover. Such a design enables the device to flexibly adapt to cable covers of different diameter sizes and improves the versatility of the device;

[0020] 3. In summary, the cable cover cutting device can fix cable covers with different diameters through structures such as the main fixing component and the auxiliary fixing component, and is flexibly applicable to cutting cable covers with different diameters. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying Figures 1-3 drawings in the embodiments of the present utility model.

[0026] Please refer to Figures 1-3 In the embodiments of the present utility model, a cable cover cutting device includes: a base 1, a column 2 is fixedly installed at the right end of the top side of the base 1, a bottom plate 3 is fixedly connected to the right side of the base 1, a groove 4 is opened at the right end of the top side of the bottom plate 3, a connecting shaft 5 is rotatably installed in the middle of the top end of the column 2, a rocker 6 is fixedly installed on the outer side of the connecting shaft 5, a grip 7 is fixedly installed at the left end of the front side of the rocker 6, a cutting cover 8 is installed at the right end of the rocker 6, and a cutting knife 9 is fixedly installed in the cutting cover 8; a pair of main fixing components and a pair of auxiliary fixing components are oppositely arranged at the front and rear ends of the top side of the bottom plate 3. The front and rear two groups of main fixing components mainly fix the left end part of the cable cover to be cut, and the front and rear two groups of auxiliary fixing components assist in fixing the left end part of the cable cover to be cut;

[0027] The main fixing component includes: a base 10, a fixed clamping plate 11, a rotating shaft 12 and a movable clamping plate 13, and the auxiliary fixing component includes: a slide rail 14, a bolt 15, a right fixing block 16, a left fixing block 110, a fixing ring 17, a pulling belt 18 and a pulling spring 19;

[0028] On the front and rear parts of the middle right end of the top side of the bottom plate 3, there are two relatively fixedly installed bases 10, and the bases 10 provide stable support for the fixed clamping plates 11; at the top of the bases 10, there are fixedly installed fixed clamping plates 11. There is a horizontally penetrating pulling hole in the middle and lower part of the fixed clamping plate 11. At the right bottom end of the fixed clamping plate 11, there is a rotatably installed rotating shaft 12. At the right end of the rotating shaft 12, there is a fixedly installed movable clamping plate 13. The rotating shaft 12 enables the movable clamping plate 13 to rotate, facilitating the adjustment of the clamping angle and position of the movable clamping plate 13. The fixed clamping plate 11 and the movable clamping plate 13 cooperate to mainly fix the cable cover. When it is necessary to fix the cable cover, the movable clamping plate 13 can be rotated to cooperate with the fixed clamping plate 11 to clamp the cable cover; there is a horizontally penetrating screw hole in the middle and lower part of the movable clamping plate 13. On the front and rear parts of the left end inside the groove 4, there are two relatively fixedly installed slide rails 14. A bolt 15 is threadedly connected to the screw hole of the movable clamping plate 13. A nut is threadedly installed on the outer side of the bolt 15 at the rear end of the screw hole. The bolt 15 can slide up and down within the slide rail 14. The slide rail 14 provides an up-and-down sliding track for the bolt 15. The bolt 15 is threadedly connected to the screw hole of the movable clamping plate 13, and the nut further fixes the position of the bolt 15. By adjusting the position of the bolt 15 in the slide rail 14, it is possible to adapt to cutting cable covers of different diameter sizes, enhancing the stability of fixing the cable cover during cutting; on the front and rear parts of the middle left end of the top side of the bottom plate 3, there are two relatively fixedly installed fixing rings 17. At the upper left end of the movable clamping plate 13, there is a fixedly installed pulling belt 18. The tail end of the pulling belt 18 can pass through the pulling hole of the fixed clamping plate 11. At the tail end of the pulling belt 18, there is a fixedly installed pulling spring 19. The tail end of the pulling spring 19 can pass through the pulling hole of the fixed clamping plate 11, and the tail end of the pulling spring 19 can be movably connected to the right end of the fixing ring 17. The fixing ring 17 is used to connect the pulling spring 19. The pulling belt 18 and the pulling spring 19 cooperate to provide additional pulling force after the fixed clamping plate 11 and the movable clamping plate 13 clamp the cable cover, ensuring that the cable cover will not loosen or move during the cutting process and further enhancing the fixing effect.

[0029] In the embodiment of the present utility model, the fixed clamping plate 11 is in the shape of an arc plate that is convex on the left and concave on the right, facilitating fitting and fixing the left end of the cable cover. There is a distance between the top end of the movable clamping plate 13 and the top end of the fixed clamping plate 11. When cutting a cable cover with a smaller diameter, it is convenient for the pulling belt 18 to pull the upper inner end of the movable clamping plate 13 to bend towards the inside of the fixed clamping plate 11, thereby fixing the right end of the cable cover with a smaller size. The movable clamping plate 13 is in the shape of an arc plate that is concave on the left and convex on the right, facilitating fitting and fixing the right end of the cable cover.

[0030] In the embodiment of the present utility model, the longitudinal section of the slide rail 14 is in an arc shape that is concave on the left and convex on the right, facilitating the up-and-down sliding of the bolt 15. The rotating shaft 12 is located at the center of the circle of the slide rail 14 in the longitudinal section, ensuring that when the movable clamping plate 13 rotates left and right, the bolt 15 will not get stuck at the slide rail 14. The distance between the front and rear slide rails 14 is greater than the distance between the front and rear movable clamping plates 13, and the rear sides of the front and rear slide rails 14 are in active contact with the front sides of the front and rear movable clamping plates 13, ensuring that there is no interference between the movable clamping plate 13 and the slide rail 14 when the movable clamping plate 13 rotates to the right.

[0031] In the embodiment of the present utility model, a right fixing block 16 is fixedly installed at the upper end of the left side of the movable clamping plate 13. The right fixing block 16 is in the shape of an arc plate that is concave on the left, convex on the right, wider at the top and narrower at the bottom, which can better fit the shape of the cable cover. Especially for the right end of a smaller cable cover, it can provide a more stable fixing effect. The arc plate design can increase the contact area with the cable cover, making the fixing more reliable and preventing the cable cover from loosening or displacing during the cutting process. The material of the right fixing block 16 is rubber, which will not obstruct the cable cover when cutting a cable cover with a larger diameter. Rubber has good elasticity and flexibility, can provide a certain buffering effect when fixing the cable cover, avoid damaging the cable cover. At the same time, rubber has a relatively large friction force, which can enhance the stability of the fixing and has good flexibility.

[0032] In the embodiment of the present utility model, the material of the pulling belt 18 is a mixture of elastic fiber and polyester fiber. The combination of the high strength and wear resistance of polyester fiber and the toughness of elastic fiber makes the mixture have strong durability. The material made of this is not easily damaged by daily friction and pulling, and has a longer service life. It cooperates with the pulling spring 19 and the fixing ring 17 to assist in fixing the cable cover to be cut during the pulling process.

[0033] In the embodiment of the present utility model, there is a distance between the tail end of the pulling spring 19 and the fixing ring 17 under normal circumstances. When it is necessary to fix a cable cover with a smaller diameter, the pulling spring 19 can be pulled to hook the fixing ring 17 to drive the movable clamping plate 13 to rotate left to fix the cable cover; when it is necessary to fix a cable cover with a larger diameter, the pulling spring 19 can be removed from the fixing ring 17, and no longer restrict the right rotation of the movable clamping plate 17.

[0034] In the embodiment of the present utility model, a left fixing block 110 is fixedly installed at the lower middle part of the inner side of the fixed clamping plate 11. The left fixing block 110 is made of rubber and is in the shape of an arc plate that is convex on the left, concave on the right, wider at the top and narrower at the bottom. This shape design corresponds to the shape of the right fixing block 16 and works together to better fix the cable cover. The arc plate shape that is convex on the left and concave on the right can closely fit the shape of the cable cover, especially providing stable support and fixation for the left end of the cable cover. The design that is wider at the top and narrower at the bottom can adapt to cable covers of different sizes and is more flexible during the fixation process. Such a design helps to improve the reliability and stability of the cable cover fixation and prevent the cable cover from shaking or shifting during use.

[0035] Working principle: When performing the cable cover cutting operation, first adjust the position of the bolt 15 in the slide rail 14 according to the diameter size of the cable cover, and then rotate the movable clamping plate 13 to cooperate with the fixed clamping plate 11 to clamp the cable cover; for a cable cover with a smaller diameter, the pull belt 18 and the tension spring 19 cooperate to pull the upper end of the inner side of the movable clamping plate 13 to bend towards the inside of the fixed clamping plate 11 to further fix the right end of the cable cover; for a cable cover with a larger diameter, the tension spring 19 can be removed from the fixed ring 17, and in cooperation with the bolt 15, the slide rail 14, and the nut, the movable clamping plate 13 and the fixed clamping plate 11 are opened at a larger angle to adapt to the large-diameter cable cover. After fixing the cable cover, the operator operates the rocker 7 through the handle to make the cutting knife 9 perform the cutting operation on the cable cover.
