Description

Technical Field

[0001] This application relates to the field of refrigeration appliance testing technology, and in particular to a device for processing thermocouple wires for testing. Background Technology

[0002] Currently, when refrigeration appliances are tested in the laboratory, thermocouple wires are used for temperature measurement, with each prototype requiring approximately dozens of thermocouple wires. Furthermore, the temperature-sensing ends of the thermocouple wires are prone to breakage. Therefore, after each test, the ends of the thermocouple wires must be repaired. Repairing the thermocouple wires requires stripping the outer sheath and then sequentially stripping the inner sheath of the multiple strands of wire before twisting them together, which is time-consuming and results in low testing efficiency for refrigeration appliances.

[0003] A related technology includes a thermocouple wire stripping tool, comprising a wire feeding mechanism and a stripping mechanism. The wire feeding structure includes a driving wheel and a driven wheel, with a wire threading gap defined between them. The thermocouple wire passes through the wire threading gap and through the driving wheel and driven wheel, and is fed by the relative rotation of the driving wheel and driven wheel. The stripping mechanism includes a front cutting blade group and a rear cutting blade group. The front cutting blade group includes a front lower cutting blade and a front upper cutting blade, and the rear cutting blade group includes a rear lower cutting blade and a rear upper cutting blade. The front lower cutting blade and the front upper cutting blade face each other, and the rear lower cutting blade and the rear upper cutting blade face each other. The outer sheath of the thermocouple wire is stripped by the cooperation of the front cutting blade group and the rear cutting blade group.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] After stripping the outer sheath and inner sheath of the thermocouple wire, it is still necessary to twist the stripped thermocouple wire cores together. Moreover, the stripping length of the thermocouple wire is not easy to control, resulting in low processing efficiency of the thermocouple wire required for testing, which in turn leads to low testing efficiency of refrigeration equipment.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0008] This disclosure provides a thermocouple wire processing apparatus for testing, which can efficiently strip thermocouple wires while precisely controlling the stripping length of thermocouple wires, thereby improving the processing efficiency of thermocouple wires for testing and thus improving the testing efficiency of refrigeration appliances.

[0009] In some embodiments, the thermocouple wire processing apparatus for testing includes: a guide portion, a thermocouple wire fixing portion, and a wire cutter. The thermocouple wire fixing portion is disposed within the guide portion, and its outer wall is rotatably connected to the inner wall of the guide portion; the wire cutter is disposed at the upper end of the guide portion, and its inner side is provided with a cutting hole, through which the end of the thermocouple wire can extend into the guide portion; wherein, the end of the thermocouple wire to be processed can be fixed on the thermocouple wire fixing portion, and when the thermocouple wire fixing portion is driven to rotate, the thermocouple wire fixing portion can move along the inner wall of the guide portion toward or away from the wire cutter.

[0010] Optionally, the guide portion includes a cylinder and a threaded guide rail. The threaded guide rail is disposed on the inner wall of the cylinder, and the outer wall of the thermocouple wire fixing portion is threadedly connected to the threaded guide rail, so that the thermocouple wire fixing portion moves along the inner wall of the cylinder toward or away from the tangent when driven to rotate.

[0011] Optionally, the outer peripheral wall of the cylinder is provided with an operating port, which communicates with the interior of the cylinder.

[0012] Optionally, the thermocouple wire fixing part includes: a support base and a wire clamp. The outer wall of the support base is rotatably connected to the inner wall of the guide part; the wire clamp is disposed on the side wall of the support base facing the wire cutter and is used to clamp and fix the end of the thermocouple wire.

[0013] Optionally, the support base has a transmission rod on its side wall facing away from the tangent. One end of the transmission rod is connected to the side wall of the support base, and the other end extends out along the lower end of the guide.

[0014] Optionally, the wire cutter includes: a first cutting portion and a second cutting portion. The first cutting portion is slidably configured; the second cutting portion is configured opposite to the first cutting portion; wherein the cutting hole is jointly enclosed by the first cutting portion and the second cutting portion, and the first cutting portion and the second cutting portion can slide towards or away from each other to adjust the size of the cutting hole.

[0015] Optionally, the wire cutter further includes a mounting base. A receiving groove is provided on the inner side of the mounting base, and both the first cutting portion and the second cutting portion are disposed within the receiving groove, with both the first cutting portion and the second cutting portion slidably connected to the inner wall of the receiving groove.

[0016] Optionally, a first elastic support is provided between the first cutting part and the second cutting part, a second elastic support is provided between the side wall of the first cutting part facing away from the second cutting part and the inner wall of the receiving groove, and a third elastic support is provided between the side wall of the second cutting part facing away from the first cutting part and the inner wall of the receiving groove.

[0017] Optionally, the thermocouple wire processing apparatus for testing further includes a driving device. The driving device is disposed below the guide portion, and its output end is connected to the thermocouple wire fixing portion for driving the thermocouple wire fixing portion to rotate.

[0018] Optionally, the thermocouple wire processing device for testing further includes a base. The base is disposed below the drive device, and is connected to the outer wall of the guide via a support arm, with the drive device movably connected to the base.

[0019] The thermocouple wire processing apparatus for testing provided in this disclosure can achieve the following technical effects:

[0020] When processing thermocouple wires, a small section of the outer sheath is stripped from the end of the wire, and the exposed core is passed through the cutting hole of a wire cutter and inserted into the guide section. The end of the thermocouple wire is fixed in place by the wire fixing part. By driving the wire fixing part to rotate within the guide section, the wire fixing part moves away from the wire cutter. Simultaneously, the end of the thermocouple wire is pulled away from the wire cutter, thus stripping away both the outer sheath and the inner sheath of the core through the wire cutter. During the stripping process, the rotation of the wire fixing part causes the stripped core to twist and entangle together, eliminating the need for subsequent twisting. By controlling the number of rotations of the wire fixing part, the distance the wire fixing part moves away from the wire cutter can be precisely controlled, thereby precisely controlling the stripping length of the thermocouple wire. By using the above-mentioned stripping method, the stripping length of the thermocouple wire can be precisely controlled while stripping the thermocouple wire efficiently, thereby improving the processing efficiency of the thermocouple wire used for testing and thus improving the testing efficiency of refrigeration equipment.

[0037] Unless otherwise stated, the term "multiple" means two or more.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figure 1-7 As shown, in some embodiments, a test thermocouple wire processing apparatus includes: a guide portion 100, a thermocouple wire fixing portion 200, and a wire cutter 300. The thermocouple wire fixing portion 200 is disposed within the guide portion 100, and its outer wall is rotatably connected to the inner wall of the guide portion 100. The wire cutter 300 is disposed at the upper end of the guide portion 100, and its inner side is provided with a cutting hole 301, through which the end of the thermocouple wire can extend into the guide portion 100. The end of the thermocouple wire to be processed can be fixed on the thermocouple wire fixing portion 200. When the thermocouple wire fixing portion 200 is driven to rotate, it can move along the inner wall of the guide portion 100 toward or away from the wire cutter 300.

[0040] Using the thermocouple wire processing apparatus provided in this embodiment, when processing the thermocouple wire to be processed, a small section of the outer sheath is stripped from the end of the thermocouple wire, and the exposed wire core is passed through the cutting hole 301 of the wire cutter 300 and inserted into the guide portion 100. The end of the thermocouple wire is fixed by the thermocouple wire fixing portion 200. By driving the thermocouple wire fixing portion 200 to rotate within the guide portion 100, the thermocouple wire fixing portion 200 moves away from the wire cutter 300. While the thermocouple wire fixing portion 200 moves away from the wire cutter 300, the end of the thermocouple wire is pulled away from the wire cutter 300, thereby stripping the outer sheath and the inner sheath of the wire core of the thermocouple wire by the wire cutter 300. During the stripping process of the thermocouple wire, due to the rotation of the thermocouple wire fixing portion 200, the stripped wire core is twisted and wrapped together, eliminating the need for subsequent twisting operations. By controlling the number of rotations of the thermocouple wire fixing part 200, the movement distance of the thermocouple wire fixing part 200 away from the wire cutter 300 can be precisely controlled, thereby accurately controlling the stripping length of the thermocouple wire. Through this stripping method, the stripping length of the thermocouple wire can be precisely controlled while efficiently stripping it, improving the processing efficiency of the thermocouple wire for testing, and thus improving the testing efficiency of refrigeration equipment.

[0041] Optionally, the wire cutter 300 is detachably disposed at the upper end of the guide portion 100. In this way, when passing the end of the thermocouple wire through the cutting hole 301 of the wire cutter 300, the wire cutter 300 can be detached from the upper end of the guide portion 100 for the wire threading operation, thereby improving the wire threading efficiency of the thermocouple wire.

[0042] Optionally, the wire cutter 300 is partially inserted into the upper port of the guide portion 100, and a portion of the outer wall of the wire cutter 300 is movably connected to the inner wall of the upper port of the guide portion 100, so that the wire cutter 300 can be detached from the guide portion 100. This partial insertion of the wire cutter 300 into the upper port of the guide portion 100 enables a detachable connection between the wire cutter 300 and the guide portion 100, improving the efficiency of assembling and disassembling the wire cutter 300.

[0043] Optionally, the guide portion 100 includes a cylindrical body 110 and a threaded guide rail 120. The threaded guide rail 120 is disposed on the inner wall of the cylindrical body 110, and the outer wall of the thermocouple wire fixing portion 200 is threadedly connected to the threaded guide rail 120, so that the thermocouple wire fixing portion 200 can move along the inner wall of the cylindrical body 110 toward or away from the tangent 300 when driven to rotate. In this way, the guide portion 100 is divided into the cylindrical body 110 and the threaded guide rail 120, and the thermocouple wire fixing portion 200 is threadedly connected to the inner wall of the cylindrical body 110 through the threaded guide rail 120. When the thermocouple wire fixing portion 200 is driven to rotate, under the action of the threaded guide rail 120, the thermocouple wire fixing portion 200 can move along the inner wall of the cylindrical body 110 toward or away from the tangent 300. The thermocouple wire fixing part 200 can move more precisely along the inner wall of the cylinder 110 under the action of the threaded connection, thereby more accurately controlling the movement distance of the thermocouple wire fixing part 200 and thus more accurately controlling the stripping length of the thermocouple wire.

[0044] Optionally, the cylinder 110 has a cylindrical structure, and the threaded guide rail 120 extends from top to bottom along the inner wall of the cylinder 110. In this way, when the thermocouple wire fixing part 200 is driven to rotate, it can move upward or downward under the action of the threaded guide rail 120.

[0045] Optionally, the outer peripheral wall of the cylinder 110 is provided with an operating port 111, which communicates with the interior of the cylinder 110. This allows the user to operate the thermocouple wire fixing part 200 inside the cylinder 110 from the outside of the cylinder 110. The user's hand can use the operating port 111 to fix the end of the thermocouple wire extending into the cylinder 110 onto the thermocouple wire fixing part 200. When the thermocouple wire is stripped, the end of the thermocouple wire can also be removed from the thermocouple wire fixing part 200 through the operating port 111, thus facilitating the removal of the processed thermocouple wire and improving the processing efficiency of the thermocouple wire.

[0046] Optionally, two operating ports 111 are provided, and the two operating ports 111 are symmetrically distributed on the outer peripheral walls of both sides of the cylinder 110 about the axis of the cylinder 110. In this way, the user's hands can be used to remove and install thermocouple wires through the two operating ports 111, thereby improving the efficiency of thermocouple wire removal and installation.

[0047] Optionally, the length of the operating port 111 along the axial direction of the cylinder 110 is greater than or equal to two-thirds of the length of the cylinder 110. This increases the coverage area of ​​the operating port 111, and the length of the operating port 111 can cover most of the movement trajectory of the thermocouple wire fixing part 200, making it convenient to operate the thermocouple wire fixing part 200 through the operating port 111.

[0048] Specifically, along the axial direction of the cylinder 110, the length of the operating port 111 is equal to two-thirds of the length of the cylinder 110.

[0049] Optionally, the thermocouple wire fixing part 200 includes a support base 210 and a wire clamp 220. The outer wall of the support base 210 is rotatably connected to the inner wall of the guide part 100; the wire clamp 220 is disposed on the side wall of the support base 210 facing the wire cutter 300 and is used to clamp and fix the end of the thermocouple wire. In this way, the thermocouple wire fixing part 200 is divided into a support base 210 and a wire clamp 220. By utilizing the rotatable connection between the support base 210 and the inner wall of the guide part 100 to provide support for the wire clamp 220, the movement stability of the thermocouple wire fixing part 200 can be improved. By fixing the end of the thermocouple wire with the wire clamp 220, the end of the thermocouple wire can be efficiently assembled and disassembled, further improving the processing efficiency of the thermocouple wire.

[0050] Optionally, the support 210 is a cylindrical support, and the outer peripheral wall of the support 210 is provided with a threaded protrusion 211, which is embedded in the threaded guide rail 120. In this way, the cylindrical support 210 can better cooperate with the cylinder 110. By utilizing the cooperation between the threaded protrusion 211 on the outer peripheral wall of the support 210 and the threaded guide rail 120 on the inner wall of the cylinder 110, a threaded rotational connection between the support 210 and the cylinder 110 can be realized. When the support 210 is driven to rotate, the support 210 can move more precisely upward or downward under the cooperation of the threaded guide rail 120 and the threaded protrusion 211.

[0051] Optionally, along the axial direction of the cylinder 110, the length of the support 210 is less than or equal to one-sixth of the length of the cylinder 110. In this case, if the length of the support 210 is greater than one-sixth of the length of the cylinder 110, the support 210 becomes relatively large, occupying excessive space inside the cylinder 110 and reducing its range of motion within the cylinder 110. Therefore, setting the length of the support 210 to be less than or equal to one-sixth of the length of the cylinder 110 allows the support 210 to provide stable support while minimizing the space it occupies, ensuring its range of motion within the cylinder 110, and thus better adapting to the processing of thermocouple wires with different stripping length requirements.

[0052] Optionally, the wire clamp 220 includes a support frame 221, a first clamping arm 222, and a second clamping arm 223. The support frame 221 is disposed on the upper side wall of the support base 210. The first clamping arm 222 and the second clamping arm 223 are rotatably connected to the support frame 221, and the first clamping arm 222 and the second clamping arm 223 are arranged opposite to each other. The upper ends of the first clamping arm 222 and the second clamping arm 223 can move towards each other or away from each other. Thus, when the upper ends of the first clamping arm 222 and the second clamping arm 223 move towards each other, the upper ends of the first clamping arm 222 and the second clamping arm 223 abut against each other to clamp and fix them. When the upper ends of the first clamping arm 222 and the second clamping arm 223 move away from each other, the upper ends of the first clamping arm 222 and the second clamping arm 223 separate from each other, causing the clamped thermocouple wire end to fall off.

[0053] Optionally, the middle regions of both the first clamping arm 222 and the second clamping arm 223 are rotatably connected to the support frame 221. Thus, when the upper ends of the first clamping arm 222 and the second clamping arm 223 move in opposite directions, their lower ends move in opposite directions. When the upper ends of the first clamping arm 222 and the second clamping arm 223 move in opposite directions, their lower ends move in opposite directions, utilizing the lever principle to clamp or separate the first clamping arm 222 and the second clamping arm 223.

[0054] Optionally, a support spring 224 is provided between the first clamping arm 222 and the second clamping arm 223. One end of the support spring 224 is connected to the lower end region of the first clamping arm 222, and the other end of the support spring 224 is connected to the lower end region of the second clamping arm 223. Under the action of the support spring 224, the upper end regions of the first clamping arm 222 and the second clamping arm 223 tend to move in opposite directions. In this way, by providing the support spring 224, the upper end regions of the first clamping arm 222 and the second clamping arm 223 can move in opposite directions to clamp and fix them. When it is necessary to separate the upper end regions of the first clamping arm 222 and the second clamping arm 223 by moving in opposite directions, the lower end regions of the first clamping arm 222 and the second clamping arm 223 can be pressed to make the lower end regions of the first clamping arm 222 and the second clamping arm 223 move in opposite directions, the support spring 224 is compressed, thereby making the upper end regions of the first clamping arm 222 and the second clamping arm 223 move in opposite directions to separate.

[0055] Optionally, when the upper ends of the first clamping arm 222 and the second clamping arm 223 are clamped together, the clamping surfaces of the first clamping arm 222 and the second clamping arm 223 are located on the axis of the cylinder 110. In this way, the thermocouple wire extending into the cylinder 110 can always be parallel to the axis of the cylinder 110 after being fixed by the wire clamp 220. When the end of the thermocouple wire is pulled by the support seat 210 to move away from the tangent 300, the thermocouple wire is not easy to deviate, and the part of the thermocouple wire located in the tangent hole 301 is not easy to break.

[0056] Optionally, a transmission rod 230 is provided on the side wall of the support base 210 facing away from the wire cutter 300. One end of the transmission rod 230 is connected to the side wall of the support base 210, and the other end extends along the lower end of the guide portion 100. In this way, the transmission rod 230 can drive the support base 210 to rotate, thereby causing the support base 210 to move along the inner wall of the guide portion 100, pulling the thermocouple wire gradually through the cutting hole 301 of the wire cutter 300 to complete the wire stripping operation. The transmission rod 230 facilitates the driving of the support base 210, and the user can complete the driving operation of the support base 210 without entering the inside of the guide portion 100.

[0057] Optionally, the lower end of the transmission rod 230 extends along the lower port of the cylinder 110, and one end of the transmission rod 230 is connected to the center of the lower side wall of the support base 210. In this way, when the transmission rod 230 is driven to rotate, the driving force can be evenly transmitted to the support base 210, driving the support base 210 and the transmission rod 230 to rotate synchronously.

[0058] Optionally, the length of the transmission rod 230 along the axial direction of the cylinder 110 is greater than or equal to the length of the cylinder 110. In this way, since the support seat 210 can move up and down along the inner wall of the cylinder 110, when the support seat 210 moves upward, it can drive the transmission rod 230 to move towards the upper end of the cylinder 110. To ensure the normal transmission of the transmission rod 230, the length of the transmission rod 230 is set to be greater than or equal to the length of the cylinder 110, so that the length of the transmission rod 230 can match the range of motion of the support seat 210.

[0059] Optionally, the length of the transmission rod 230 is equal to the length of the cylinder 110 along its axial direction. Since the support seat 210 has a certain length, setting the length of the transmission rod 230 to be equal to the length of the cylinder 110 allows the length of the transmission rod 230 to match the range of motion of the support seat 210. Even if the support seat 210 moves to the uppermost end of the cylinder 110, the transmission rod 230, supported by the length of the support seat 210, still has a portion extending beyond the lower end of the cylinder 110, enabling the transmission rod 230 to transmit power normally.

[0060] Optionally, such as Figure 4 and Figure 5As shown, the wire cutter 300 includes a first cutting section 310 and a second cutting section 320. The first cutting section 310 is slidably disposed; the second cutting section 320 is disposed opposite to the first cutting section 310; wherein, a wire cutting hole 301 is jointly enclosed by the first cutting section 310 and the second cutting section 320, and the first cutting section 310 and the second cutting section 320 can slide towards or away from each other to adjust the size of the wire cutting hole 301. In this way, the first cutting section 310 and the second cutting section 320 work together to strip the thermocouple wire inserted in the wire cutting hole 301. Since the diameter of the thermocouple wires varies, the first cutting section 310 and the second cutting section 320 are disposed opposite to each other, and the size of the wire cutting hole 301 is changed by sliding the first cutting section 310 and the second cutting section 320 towards or away from each other, so that the wire cutting hole 301 can be adapted to the wire stripping operation of thermocouple wires of different diameters.

[0061] Optionally, the first cutting section 310 includes a first blade 311, and the second cutting section 320 includes a second blade 321. The first blade 311 and the second blade 321 are disposed opposite to each other, with the first blade 311 positioned above the second blade 321. The cutting edges of the first blade 311 and the second blade 321 slide against each other, and the tangent hole 301 is enclosed by the cutting edges of the first blade 311 and the second blade 321. In this way, the thermocouple wire is threaded through the tangent hole 301 enclosed by the cooperation of the cutting edges of the first blade 311 and the second blade 321. When the thermocouple wire is pulled through the tangent hole 301, the cooperation of the cutting edges of the first blade 311 and the second blade 321 is used to strip the thermocouple wire. Positioning the first blade 311 above the second blade 321 prevents interference when the first blade 311 and the second blade 321 slide towards each other, allowing for better adjustment of the size of the tangent hole 301.

[0062] Optionally, the first cutting section 310 further includes a first slide 312, and the second cutting section 320 further includes a second slide 322. The first slide 312 and the second slide 322 are disposed opposite to each other. The first blade 311 is disposed on the side wall of the first slide 312 facing the second slide 322, and the second blade 321 is disposed on the side wall of the second slide 322 facing the first slide 312. When the first blade 311 and the second blade 321 slide towards each other, the first slide 312 and the second slide 322 also slide towards each other. When the first blade 311 and the second blade 321 slide away from each other, the first slide 312 and the second slide 322 also slide away from each other. In this way, by providing the first slide 312 to support the first blade 311 and by providing the second slide 322 to support the second blade 321, the sliding stability of the first blade 311 and the second blade 321 can be improved, thereby enabling more stable stripping of thermocouple wires.

[0063] Optionally, the first slide 312 and the second slide 322 are located in the same plane. This makes the sliding stability of the first slide 312 and the second slide 322 in opposite or opposite directions higher, thereby providing more stable support for the first blade 311 and the second blade 321.

[0064] Optionally, the wire stripper 300 further includes a mounting base 330. A receiving groove 331 is provided inside the mounting base 330. The first cutting portion 310 and the second cutting portion 320 are both disposed within the receiving groove 331, and both the first cutting portion 310 and the second cutting portion 320 are slidably connected to the inner wall of the receiving groove 331. Thus, by providing the mounting base 330, the first cutting portion 310 and the second cutting portion 320 are slidably disposed within the receiving groove 331. The mounting base 330 provides sliding support for the first cutting portion 310 and the second cutting portion 320, further improving the stability of the first cutting portion 310 and the second cutting portion 320, thereby enabling more stable stripping of thermocouple wires.

[0065] Optionally, both the first slide block 312 and the second slide block 322 are slidably connected to the inner wall of the receiving groove 331. Thus, by slidably connecting the first slide block 312 and the second slide block 322 to the inner wall of the receiving groove 331, and since the first blade 311 is disposed on the side wall of the first slide block 312 and the second blade 321 is disposed on the side wall of the second slide block 322, the sliding of the first slide block 312 and the second slide block 322 in opposite or opposite directions drives the first blade 311 and the second blade 321 to slide in opposite or opposite directions.

[0066] For example, the inner wall of the receiving groove 331 is provided with slide rails at the positions corresponding to the first slide 312 and the second slide 322. The lower sidewalls of the first slide 312 and the second slide 322 are provided with sliders. The slider of the lower sidewall of the first slide 312 is embedded in the corresponding slide rail, and the slider of the lower sidewall of the second slide 322 is embedded in the corresponding slide rail, thereby realizing the sliding connection between the first slide 312, the second slide 322 and the inner wall of the receiving groove 331.

[0067] Optionally, such as Figure 4As shown, a first elastic support 332 is provided between the first cutting section 310 and the second cutting section 320; a second elastic support 333 is provided between the side wall of the first cutting section 310 facing away from the second cutting section 320 and the inner wall of the receiving groove 331; and a third elastic support 334 is provided between the side wall of the second cutting section 320 facing away from the first cutting section 310 and the inner wall of the receiving groove 331. Thus, under the action of the first elastic support 332, the first cutting section 310 and the second cutting section 320 have potential energy for sliding in opposite directions; and under the action of the second elastic support 333 and the third elastic support 334, the first cutting section 310 and the second cutting section 320 have potential energy for sliding in opposite directions. Through the combined action of the first elastic support 332, the second elastic support 333 and the third elastic support 334, the first cutting part 310 and the second cutting part 320 can both maintain a state of mutual contact to jointly enclose the tangent hole 301, and can also easily slide backward under external force to enlarge the tangent hole 301.

[0068] Optionally, the second elastic support portion 333 and the third elastic support portion 334 have the same structure, the same pressure applied by the second elastic support portion 333 and the third elastic support portion 334, and the sum of the pressures applied by the second elastic support portion 333 and the third elastic support portion 334 is equal to the elastic force applied by the first elastic support portion 332. In this way, the supporting forces on the opposing and back-to-back sidewalls of the first cutting portion 310 and the second cutting portion 320 are balanced, which can both abut against each other to limit the tangent hole 301, and facilitate the sliding adjustment of the first cutting portion 310 and the second cutting portion 320.

[0069] For example, the first elastic support 332, the second elastic support 333, and the third elastic support 334 are all springs. However, the springs of the second elastic support 333 and the third elastic support 334 are of the same type and have the same elastic force when compressed to the same volume. The spring of the first elastic support 332 is different from the springs of the second elastic support 333 and the third elastic support 334. Furthermore, the elastic force of the third elastic support 334 when compressed to the same volume as the second elastic support 333 and the third elastic support 334 is twice that of the second elastic support 333.

[0070] Optionally, the first elastic support 332 is disposed between the opposing side walls of the first slide 312 and the second slide 322, the second elastic support 333 is disposed between the side wall of the first slide 312 facing away from the second slide 322 and the inner wall of the receiving groove 331, and the third elastic support 334 is disposed between the side wall of the second slide 322 facing away from the first slide 312 and the inner wall of the receiving groove 331.

[0071] Optionally, spring grooves are provided on the opposite sidewalls of the first slide 312 and the second slide 322. Guide posts are provided inside the spring grooves. One end of the first elastic support 332 is fitted onto the guide post in the spring groove of the first slide 312, and the other end of the first elastic support 332 is fitted onto the guide post in the spring groove of the second slide 322, extending into the spring groove of the second slide 322. This allows the elastic force applied by the first elastic support 332 to be more evenly distributed on the first slide 312 and the second slide 322, keeping the first slide 312 and the second slide 322 in a stable state.

[0072] Optionally, the first slide 312 has a first handle on its side wall facing away from the second slide 322, and the second slide 322 has a second handle on its side wall facing away from the first slide 312. Both the first and second handles extend along the edge of the receiving groove 331 to the outside of the mounting base 330. In this way, the first slide 312 and the second slide 322 can be operated to slide in opposite directions or away from each other by means of the first handle and the second handle, so that the first blade 311 and the second blade 321 can slide in opposite directions or away from each other, thereby adjusting the size of the tangent hole 301 more efficiently.

[0073] For example, when stripping thermocouple wires, the user can adjust the size of the cutting hole 301 according to the diameter of the thermocouple wire. When the diameter of the thermocouple wire is relatively small, pressing the first handle and the second handle causes the first slide 312 and the second slide 322 to slide in opposite directions, reducing the size of the cutting hole 301 and allowing for better stripping of the thermocouple wire. When the diameter of the thermocouple wire is relatively large, pulling the first handle and the second handle to both sides causes the first slide 312 and the second slide 322 to slide in opposite directions, increasing the inner diameter of the cutting hole 301. The thermocouple wire is then passed through the cutting hole 301. Releasing the pull on the first handle and the second handle further compresses the second elastic support 333 and the third elastic support 334, increasing their elasticity. This causes the first blade 311 and the second blade 321 to compress the thermocouple wire, performing the stripping operation. After the thermocouple wire stripping operation is completed, in order to remove the twisted thermocouple wire core from the cutting hole 301, the user can pull the first handle and the second handle to both sides, so that the first blade 311 and the second blade 321 separate, the cutting hole 301 is further enlarged, so that the twisted thermocouple wire core can be smoothly removed.

[0074] Optionally, such as Figure 7As shown, the mounting base 330 has a disc-shaped structure. A mounting plug 340 is provided on the lower end face of the mounting base 330. The mounting plug 340 is detachably inserted into the upper port of the cylinder 110, and a through-hole is provided at the center of the mounting plug 340. In this way, the mounting base 330 is detachably inserted into the upper port of the cylinder 110 via the mounting plug 340, and the thermocouple wire passing through the tangent hole 301 can extend into the cylinder 110 through the through-hole.

[0075] Optionally, such as Figure 6 As shown, the tangent hole 301 includes a first hole 302 and a second hole 303, which are arranged radially along the mounting base 330. The connection point of the first hole 302 and the second hole 303 is located on the axis of the mounting base 330. In this way, since the thermocouple wire usually has two cores, the tangent hole 301 is divided into a first hole 302 and a second hole 303 to match the two cores of the thermocouple wire. This allows the two cores to pass through the first hole 302 and the second hole 303 respectively and extend into the cylinder 110. When the thermocouple wire is pulled, the outer sheath of the two cores can be better stripped by the tangent hole 301.

[0076] Combination Figure 8 As shown, in some embodiments, the thermocouple wire processing apparatus for testing further includes a driving device 400. The driving device 400 is disposed below the guide portion 100, and its output end is connected to the thermocouple wire fixing portion 200, used to drive the thermocouple wire fixing portion 200 to rotate. Thus, by using the driving device 400 to drive the thermocouple wire fixing portion 200 to rotate, the thermocouple wire fixing portion 200 is driven. While being driven to rotate, the thermocouple wire fixing portion 200 rises and falls along the inner wall of the guide portion 100, thereby completing the stripping and twisting operations of the thermocouple wire, improving the processing efficiency of the thermocouple wire.

[0077] Optionally, the drive device 400 is a motor, and the output end of the drive device 400 is connected to the support base 210 fixed with thermocouple wires via a transmission rod 230. In this way, the transmission rod 230 is driven to rotate by the motor, thereby driving the support base 210 to rotate. While rotating, the support base 210 rotates and rises and falls inside the cylinder 110 under the action of the threaded connection.

[0078] Optionally, the thermocouple wire processing apparatus for testing further includes a base 500. The base 500 is disposed below the drive device 400, and is connected to the outer wall of the guide portion 100 via a support arm 510. The drive device 400 is movably connected to the base 500. Thus, the base 500 provides support for the guide portion 100 and the drive device 400, allowing the drive device 400 to move up and down along with the thermocouple wire fixing portion 200 when the drive device 400 drives the thermocouple wire fixing portion 200 to rotate and rise.

[0079] Optionally, the upper side wall of the base 500 is provided with a sliding bracket 520, and the drive device 400 is slidably mounted on the sliding bracket 520, and can slide up and down along the sliding bracket 520. In this way, the sliding bracket 520 can provide a force point for driving the drive device 400, and at the same time enable the drive device 400 to slide up and down along the sliding bracket 520, thereby improving the sliding stability of the drive device 400.

[0080] Optionally, the thermocouple wire processing apparatus for testing further includes a controller 600. The controller 600 is electrically connected to the drive device 400 and is used to control the drive stroke of the drive device 400. Thus, the drive stroke of the drive device 400 determines the number of rotations of the support 210, and consequently the lifting distance of the support 210. The controller 600 controls the drive stroke of the drive device 400 according to the stripping length required by the user, thereby precisely controlling the stripping length of the thermocouple wire and further improving the processing efficiency of the thermocouple wire.

[0081] Optionally, the upper sidewall of the base 500 is also provided with an input module 700, which is electrically connected to the controller 600 and is used to input the required stripping length of the thermocouple wire. In this way, the user can input the required stripping length through the input module 700, the controller 600 obtains the stripping length input by the user, determines the drive stroke of the drive device 400 according to the corresponding relationship, and then controls the drive stroke of the drive device 400.

[0082] For example, the input module 700 can be an interactive module such as a button or a touch screen. The user inputs the desired target stripping length, and the controller 600 can determine the corresponding drive stroke based on the obtained target stripping length.

[0083] Understandably, different drive strokes of the drive device 400 correspond to different wire stripping lengths. These correspondences are pre-stored in the controller 600. When the controller 600 obtains the target wire stripping length input by the user, it can determine the corresponding target drive stroke, which will not be elaborated here.
