Description

Technical Field

[0001] This utility model relates to the field of cable slicing and sampling technology, specifically to a cable insulation layer rotary cutting and sampling device. Background Technology

[0002] Cables are widely used as a medium for transmitting electrical energy, and their safety requirements are of paramount importance. Among these requirements, cable insulation testing involves numerous aspects, such as mechanical performance testing, thermal elongation testing, and insulation withstand voltage testing. Therefore, obtaining insulation sheets that meet the required standards is crucial.

[0003] Existing cable insulation slicing devices use a flat cutting method, such as the cross-linked cable automatic slicing machine disclosed in patent document CN209755282U. The above-mentioned slicing device slices along the cable axis, cutting gradually from the cable surface towards the center. The width of the obtained insulation sample is inconsistent. In particular, the sample cut from the top of the cable is too small and often cannot meet the size requirements of the test sample. For example, the width requirement of the dumbbell-shaped sample is 12.5mm. Only when the width of the sample cut from the cable is greater than 12.5mm can the insulation sample meet the requirements. This results in a small number of test samples that meet the requirements.

[0004] Therefore, how to cut a sufficient number of insulation samples from cable specimens that meet the requirements for use has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a cable insulation layer rotary cutting sampling device to address the above-mentioned technical problems, so as to ensure that the width of the insulation sample meets the usage requirements and the cutting quantity.

[0040] Examples, such as Figures 1-4 As shown, a cable insulation layer rotary cutting sampling device includes: a fixed base plate 100, a longitudinal moving base plate 200, a sample clamp 300, a knife holder 400, and a rotary cutting knife holder 500.

[0041] The fixed base plate 100 is set in the horizontal direction.

[0042] The longitudinal sliding base plate 200 is arranged parallel to the fixed base plate 100 directly above it, and the longitudinal sliding base plate 200 and the fixed base plate 100 are slidably connected in the longitudinal direction.

[0043] There are two sample clamps 300, which are arranged one-to-one at the two transverse ends of the longitudinal base plate 200. The transverse distance between the two sample clamps 300 can be adjusted. The sample clamps 300 can clamp and fix the end of the cable sample 800 and drive the cable sample 800 to rotate.

[0044] The tool holder 400 is located at one longitudinal end of the longitudinal moving base plate 200, and the bottom end of the tool holder 400 is fixedly connected to the fixed base plate 100.

[0045] The rotary cutting blade holder 500 is arranged longitudinally between the blade holder 400 and the cable sample 800, with one end of the rotary cutting blade holder 500 connected to the blade holder 400 and the other end used to install the rotary cutting blade.

[0046] This invention employs a radial rotary cutting method, using a sample clamp 300 to fix and drive the cable sample 800 to rotate, and using a longitudinal base plate 200 to move the cable sample 800 close to the rotary cutting blade holder 500. This not only cuts out insulation samples of uniform thickness, ensuring that the width of the insulation samples meets the usage requirements, but also increases the number of insulation samples, thereby improving the sample preparation utilization rate of the cable insulation layer.

[0047] Specific embodiment 1, such as Figures 1-4 As shown, a cable insulation layer rotary cutting sampling device includes: a fixed base plate 100, a longitudinal moving base plate 200, a sample clamp 300, a knife holder 400, a rotary cutting knife holder 500, and a control component 600.

[0048] The fixed base plate 100 is set in the horizontal direction.

[0049] The longitudinal sliding base plate 200 is arranged parallel to the fixed base plate 100 directly above it. A longitudinal guide rail 110, a longitudinal sliding slider 120, and a longitudinal drive mechanism 130 are installed between the longitudinal sliding base plate 200 and the fixed base plate 100. There are two longitudinal guide rails 110, each fixedly installed at one end of the horizontal direction of the fixed base plate 100. There are two longitudinal sliding sliders 120, each slidably connected to one of the two longitudinal guide rails 110. The two transverse ends of 00 are fixedly connected to two longitudinal sliding blocks 120 one by one. The longitudinal drive mechanism 130 is fixedly installed on the fixed base plate 100. The longitudinal drive mechanism 130 is connected to the longitudinal sliding blocks 120 in a transmission manner, and the control component 600 is connected to the longitudinal drive mechanism 130 in an electrical signal manner. The control component 600 controls the longitudinal drive mechanism 130 to drive the longitudinal base plate 200 to move back and forth in the longitudinal direction above the fixed base plate 100, thereby accurately adjusting the longitudinal distance between the cable sample 800 and the rotary cutting blade.

[0050] There are two sample clamps 300, each corresponding to one end of the transverse end of the longitudinal base plate 200. A transverse guide rail 210, a transverse slider 220, and a transverse drive mechanism 230 are installed between the sample clamps 300 and the longitudinal base plate 200. There are two transverse guide rails 210, each fixedly installed at one end of the longitudinal end of the longitudinal base plate 200. There are multiple transverse sliders 220, which are slidably connected to the two transverse guide rails 210. At least one sample clamp... The bottom end of the sample clamp 300 is fixedly connected to the transverse slider 220 at one end of the transverse guide rail 210; the transverse drive mechanism 230 is fixedly installed on the longitudinal base plate 200, and the transverse drive mechanism 230 is connected to the transverse slider 220 at one or both ends of the transverse guide rail 210. The control component 600 is electrically connected to the transverse drive mechanism 230 so as to control the transverse drive mechanism 230 to drive the sample clamp 300 to move back and forth in the transverse direction above the longitudinal base plate 200, thereby accurately adjusting the transverse distance between the two sample clamps 300.

[0051] Specifically, both sample clamps 300 are six-jaw chucks used to clamp and fix the cable sample 800. One sample clamp 300 is mounted on the top of a support column 310, the bottom of which is fixedly connected to one lateral end (left end in the figure) of the longitudinal base plate 200. A drive motor 320 is also mounted on the support column 310, which is connected to the sample clamp 300 to drive the sample clamp 300 to rotate, thereby causing the cable sample 800 between the two sample clamps 300 to rotate. The other sample clamp 300 is mounted on the top of the support column 310, the bottom of which is fixedly connected to a transverse slider 220 on the other lateral end (right end in the figure) of the longitudinal base plate 200. This allows one sample clamp 300 to be fixedly connected to the longitudinal base plate 200, while the other sample clamp 300 is slidably connected to the longitudinal base plate 200, thus allowing the lateral distance between the two sample clamps 300 to be adjusted.

[0052] The tool holder 400 is vertically positioned at one end of the longitudinal direction of the longitudinal moving base plate 200, and the bottom end of the tool holder 400 is fixedly connected to the fixed base plate 100.

[0053] The rotary cutting blade holder 500 is installed longitudinally between the blade holder 400 and the cable sample 800. One end of the rotary cutting blade holder 500 is connected to the blade holder 400, and the other end is used to install the rotary cutting blade. The length of the rotary cutting blade is 30mm to 100mm, and the thickness of the rotary cutting blade is 0.1mm to 1mm.

[0054] Preferably, the rotary cutter holder 500 is slidably connected to the cutter holder 400 in the vertical direction, and a safety cover 450 for covering the outside of the rotary cutter holder 500 is installed at the top of the cutter holder 400. The safety cover 450 is a hollow cuboid.

[0055] Specifically, the blade holder 400 includes a support frame 410, a vertical guide rail 420, a lifting slider 430, and a vertical drive mechanism 440. The support frame 410 is vertically disposed on one longitudinal side of the longitudinal moving base plate 200, and its bottom end is fixedly connected to the fixed base plate 100. The vertical guide rail 420 is fixedly installed on one side of the support frame 410. The lifting slider 430 is slidably connected to the vertical guide rail 420. The rotary cutting blade holder 500 is fixedly connected to the lifting slider 430. The rotary cutter holder 500 and the cutter holder 400 are able to move relative to each other in the vertical direction. The vertical drive mechanism 440 is mounted on the support frame 410 and is connected to the lifting slider 430. The control component 600 is electrically connected to the vertical drive mechanism 440 so that the control component 600 controls the vertical drive mechanism 440 to drive the rotary cutter holder 500 to reciprocate in the vertical direction above the cutter holder 400, thereby allowing the rotary cutter holder 500 to enter and exit the safety cover 450.

[0056] More preferably, the longitudinal drive mechanism 130, the transverse drive mechanism 230 and the vertical drive mechanism 440 can be any known linear drive mechanism, such as a lead screw and slider mechanism.

[0057] More preferably, the rotary cutting sampling device further includes a protective shell 700, which is composed of a rectangular frame and a protective plate. The fixed base plate 100 is fixedly installed in the middle of the inner cavity of the protective shell 700, and the sample clamp 300, the knife holder 400, the rotary cutting knife holder 500 and the control component 600 are all located in the inner cavity of the protective shell 700.

[0058] Specifically, an openable door panel is installed on the front of the protective shell 700, and casters are provided at the bottom of the protective shell 700 to facilitate the movement of the rotary sampling device.

[0059] Specifically, the control component 600 includes a control module and a display module (specifically a display screen). The control module is fixedly installed below the fixed base plate 100, and the display module is installed above the fixed base plate 100. The display module is fixedly connected to the rectangular frame of the protective shell 700. The display module is electrically connected to the control module for inputting adjustment parameters. The control module is electrically connected to the longitudinal drive mechanism 130, the transverse drive mechanism 230, and the vertical drive mechanism 440 respectively for controlling the automatic rotary cutting operation of the cable sample 800.

[0060] The working process of the rotary cutting sampling device of this utility model is as follows:

[0061] S1: Turn on the power and operate the display screen of the control component 600 to drive the transverse drive mechanism 230 to move the transverse slider 220 to the right, thereby moving the sample clamp 300 to the right and increasing the transverse distance between the two sample clamps 300.

[0062] S2: First, open the two sample clamps 300 through the display screen of the operation control component 600, put the cable sample 800 with a cut length of 250mm to 300mm into the sample clamp 300 on the left, and make the sample clamp 300 clamp one end of the cable sample 800; then, through the display screen of the operation control component 600, make the transverse drive mechanism 230 drive the transverse slider 220 to move to the left, thereby driving the sample clamp 300 to move to the left and making the sample clamp 300 on the right clamp the other end of the cable sample 800.

[0063] S3: By operating the display screen of the control unit 600, the rotary cutter holder 500 is moved downward from inside the safety cover 450 until the rotary cutter holder 500 is flush with the cable sample 800.

[0064] S4: By operating the display screen of the control component 600, the longitudinal drive mechanism 130 moves the longitudinal slider 120 backward, thereby driving the cable sample 800 to move backward until the rotary cutting blade contacts the surface of the cable sample 800.

[0065] S5: Input the required sample thickness through the display screen of the operation control component 600, drive the sample clamp 300 to rotate through the drive motor 320, thereby driving the cable sample 800 to rotate and start the rotary cutting operation, and prepare a roll of insulation sheet with a thickness of 0.1mm to 1mm and a width of 100mm.

[0066] Compared with the prior art, this application has at least the following beneficial technical effects:

[0067] 1. The sample clamp in this utility model is a six-jaw chuck, which can increase the clamping force at both ends of the cable sample, avoid slippage of the cable sample during the rotary cutting process, thereby increasing stability and ensuring the uniformity of the cable rotary cutting thickness.

[0068] 2. In this utility model, a safety cover is installed at the top of the blade holder. When not performing rotary cutting, the rotary cutting blade holder is located inside the safety cover, which protects the operator.

[0069] 3. The sample clamp in this utility model can move forward, backward, left, and right, and the rotary cutting blade holder can move vertically, which improves the convenience of operation.

[0070] 4. This utility model is simple to operate and highly automated. It can spin-cut insulation sheets of uniform thickness, which is suitable for various tests. Compared with the axial flat cutting method, it can not only produce more insulation sheets for the same length of cable, thus improving the sample utilization rate of cable insulation, but also continuously reflect the material properties in the thickness direction of the insulation layer.

[0071] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
