Description

Technical Field

[0001] This utility model relates to the field of testing tools, specifically to a copper busbar tooth measuring tool. Background Technology

[0002] In the manufacturing process of electrical products, copper busbars are very important electrical connectors.

[0003] In current applications of high-current plug-in / plug-out scenarios, it is necessary to enhance the assembly firmness between the copper busbar and the plastic insulating shell. Therefore, barbed teeth are designed on the side edge of the copper busbar, which are called side teeth. During the injection molding process, the side teeth can form an interlocking fit with the shell.

[0004] Since these teeth are typically integrally molded with the copper busbar body, if the length of the side teeth is too large, the thickness of the outer casing in contact with the longer side teeth will be relatively thin due to the fixed dimensions of the mold. This can potentially damage the outer casing during forceful insertion and removal under high current conditions. Furthermore, the precision of these side teeth also affects the conductivity and material cost of the copper busbar, therefore, necessary inspections of the copper busbar are required before assembly.

[0005] However, these teeth are relatively small, and the quality inspection process for copper busbars generally involves manual sampling. Therefore, it is necessary to design a copper busbar tooth inspection tool that is convenient for manual and quick quality inspection. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a copper busbar tooth measuring tool, which solves the problem of inconvenience in the current manual inspection of the quality of copper busbar side teeth.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a copper busbar measuring tool, comprising a fixture for placing the copper busbar, a limiting mechanism for restricting the displacement of the copper busbar relative to the fixture, and a length measuring mechanism; It also includes a slide rail, on which the fixture is slidably connected; The upper surface of the fixture is provided with a placement platform for matching the shape of the copper busbar on the side of the length measuring mechanism. Several abutments are also slidably connected to the fixture. The sliding direction of each abutment is perpendicular to the sliding direction of the fixture, and the abutments are connected to the fixture through elastic elements. When the copper busbar is placed in place on the placement platform, each abutment is displaced by the pressure of each side tooth of the copper busbar. The length measuring mechanism is used to reflect the displacement of the block.

[0008] Preferably, the length measuring mechanism is a dial indicator, and the pin of the length measuring mechanism is perpendicular to the surface of the sliding block.

[0011] Preferably, the push rod is a screw rod and is threadedly connected to the slide rail.

[0012] Preferably, the surface height of the placement platform is lower than the top height of the fixture, and the limiting mechanism includes a positioning block fixedly connected to the surface of the placement platform.

[0013] Preferably, the surface of the positioning block is provided with a waist-shaped hole, and the placement platform is also threaded with a screw that can pass through the waist-shaped hole.

[0014] Preferably, the limiting mechanism includes a clamp on the base, including a push rod and a chuck at one end of the push rod near the fixture, the push rod being slidably connected to the base.

[0015] Preferably, a connecting plate is rotatably connected to the other end of the top rod, and a handle is rotatably connected to the base, with the middle part of the handle rotatably connected to the end of the connecting plate away from the top rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Existing copper busbar A with side teeth A1 Figure 5 As shown, its side edge has several barbed teeth A1, and the whole is plate-shaped. After inspection, if it is deemed qualified, it enters the bending, stamping and / or injection molding process. Of course, some copper busbars A may have other protruding parts A2 on their side edges, but these are not used to improve the assembly firmness with the plastic insulating shell, or although they are used to improve the assembly firmness, they do not act on the inner wall of the plastic insulating shell in the same direction after subsequent bending or stamping processes, so there is no need to consider the dimensional precision. The inspection tool proposed in this technical solution is only used for the inspection of the side teeth A1, so this technical solution does not consider the protruding parts A2.

[0022] Example 1: Please see Figure 1-5 This utility model provides the following technical solution: a copper busbar tooth measuring fixture, including a slide rail 2, a fixture 3 for placing copper busbar A, a limiting mechanism 4 for limiting the displacement of copper busbar A relative to the fixture 3, and a length measuring mechanism 5. The fixture 3 is slidably connected to the slide rail 2. The upper surface of the fixture 3 is provided with a placement platform 31 for matching the shape of copper busbar A on the side near the length measuring mechanism 5. Several abutments 321 are also slidably connected to the fixture 3. The sliding direction of each abutment 321 is perpendicular to the sliding direction of the fixture 3, and the abutments 321 are all connected to the fixture 3 through elastic elements 322. When copper busbar A is placed in place on the placement platform 31, each abutment 321 is displaced by the pressure of each side tooth A1 of copper busbar A. The length measuring mechanism 5 is used to reflect the displacement of the abutments 321.

[0023] As an optional implementation of this utility model, during testing, the copper busbar A to be tested is placed on the placement platform 31, so that the side teeth A1 of the copper busbar A are aligned with the groove 32 of the fixture 3, and the other protruding parts A2 of the copper busbar A are aligned with the corresponding notches 33 on the fixture 3. Then, the copper busbar A is positioned by the limiting mechanism 4 to ensure that the copper busbar A will not shift relative to the fixture 3 during the testing process. At this time, each abutment 321 located in the groove 32 on the fixture 3 slides accordingly due to the combined force of the elastic element 322 and the side teeth A1 on the copper busbar A - that is, each abutment 321 abuts against the side teeth A1. Then, the fixture 3 is pushed to move in the slide rail 2 so that each abutment 321 can be detected when passing the length measuring mechanism 5.

[0024] Throughout the entire testing process, the copper busbar A on the placement platform 31 is limited by the limiting mechanism 4 to ensure that the interaction between each side tooth A1 and each abutment 321 remains unchanged, thereby ensuring that the movement of each abutment 321 can accurately reflect the length of the side tooth A1, and ultimately ensuring that the final detection value of the length measuring mechanism 5 is accurate.

[0025] In this implementation, the limiting mechanism 4 can be one or more of the positioning block 41, clamp 42, and reference block 43 in embodiment 2, or other existing technical solutions, such as screws, buckles, magnetic positioning, etc. This technical solution does not specifically limit the limiting mechanism 4; the length measuring mechanism 5 should be understood as a component that measures the sliding displacement of the stop block 321 on the fixture 3. It can be the dial indicator 51 in embodiment 2 or the dial indicator 51 plus the reference block 43, or other existing technical solutions. This implementation does not further limit it; the elastic element 322 is preferably a spring.

[0026] This method ensures the accuracy of the dimensions of the side teeth A1 on the copper busbar A during manual quality inspection, avoiding misjudgments that could affect production quality and schedule. The entire manual operation process is also relatively convenient and fast, and the inspection tool is easy for quality inspectors to operate. It is also simple in structure, inexpensive, and easy to manufacture.

[0027] Example 2: Please see Figure 1-5This utility model provides the following technical solution: a copper busbar measuring tool, including a base 1, a slide rail 2, a fixture 3 for placing a copper busbar A, a limiting mechanism 4 for limiting the displacement of the copper busbar A relative to the fixture 3, and a dial indicator 51. The fixture 3 is slidably connected to the slide rail 2. The upper surface of the fixture 3 is provided with a placement platform 31 for matching the shape of the copper busbar A on the side of the dial indicator 51. Several abutments 321 are also slidably connected to the fixture 3. The sliding direction of each abutment 321 is perpendicular to the sliding direction of the fixture 3, and the abutments 321 are all connected to the fixture 3 through elastic elements 322. When the copper busbar A is placed in place on the placement platform 31, each abutment 321 is displaced by the pressure of each side tooth A1 of the copper busbar A. The slide rail 2 and the length measuring mechanism 5 are both fixedly connected to the base 1. The surface of the pin 511 of the dial indicator 51 perpendicular to the sliding direction of the abutment 321 is used to reflect the displacement of the abutment 321.

[0028] As an optional implementation of this utility model, this embodiment further limits the selection of the length measuring mechanism 5. When the fixture 3 moves in the slide rail 2 on the base 1, each abutment 321 passes sequentially through the pin 511 of the dial indicator 51, so that the actual position of the abutment 321 is measured by the dial indicator 51. Since the dial indicator 51 is also fixed on the base 1, the initial length of the pin 511 end is known. Therefore, based on the known initial position of the abutment 321, the displacement of each abutment 321 can be automatically calculated, making the detection process of the opposite tooth A1 more convenient. The dial indicator 51 can be of model ID-C150MXB, which can automatically display the calculated value directly, avoiding the complexity and error of manual calculation, and greatly improving the efficiency of manual quality inspection.

[0029] Furthermore, the slide rail 2 is U-shaped, and a push rod 21 is provided at one end of the slide rail 2 located in the sliding direction of the fixture 3.

[0030] As an optional implementation of this utility model, the fixture 3 can be pushed to slide in the slide rail 2 by a push rod 21, or two push rods 21 can be set at both ends of the sliding direction of the slide rail 2. In this way, the fixture 3 can be pushed, and the fixture 3 can be clamped at any position in the stroke.

[0031] Furthermore, the push rod 21 is a screw 211, which is threaded onto the slide rail 2.

[0032] As an optional implementation of this utility model, the use of a threaded method makes the pushing of the fixture 3 smoother and makes it easier to control the stroke. This ensures that the contact between the stop block 321 and the dial indicator 51 is more stable as the stop block 321 moves with the fixture 3, avoiding large vibrations that could affect the reading.

[0033] like Figure 2-3As shown, the surface height of the placement platform 31 is lower than the top height of the fixture 3, and the limiting mechanism 4 includes a positioning block 41 fixedly connected to the surface of the placement platform 31.

[0034] As an optional implementation of this utility model, the positioning block 41 is used to limit the copper busbar A in the length direction after it is placed on the placement platform 31; preferably, the positioning block 41 is located on the side of the placement platform 31 away from the abutment block 321, and this side is more likely to serve as the sliding starting point of the fixture 3, thereby ensuring that the copper busbar A will not be offset relative to the fixture 3 in the length direction when it moves with the fixture 3.

[0035] like Figure 2-3 As shown, the surface of the positioning block 41 is provided with a waist-shaped hole 411, and the placement platform 31 is also threaded with a screw 412 that can pass through the waist-shaped hole 411.

[0036] As an optional implementation of this utility model, the use of a waist-shaped hole 411 makes the actual installation position of the positioning block 41 adjustable, thus adapting to the limiting of copper busbars A of different lengths.

[0037] like Figure 1 and Figure 4 As shown, the limiting mechanism 4 includes a clamp 42 mounted on the base 1, a push rod 422 and a chuck 421 mounted on one end of the push rod 422 near the fixture 3, and the push rod 422 is slidably connected to the base 1.

[0038] As an optional implementation of this utility model, the limiting of the copper busbar A on the placement platform 31 should include not only the length direction but also the width direction, ensuring that the interaction force between the abutment block 321 and the side tooth A1 will not cause the copper busbar A to be pushed out when it is placed on the placement platform 31, and also ensuring that the position of the abutment block 321 is relatively fixed during the movement of the copper busbar A. Preferably, the chuck 421 can be shaped with a large length surface, such as rectangular or circular, and the contact surface of the chuck 421 should be relatively smooth to ensure that the contact friction between the copper busbar A and the chuck 421 is small, thereby reducing the vibration of the copper busbar A. Of course, for the limiting of the push rod 422 after sliding, common existing technologies such as magnetic attraction, buckle, pin, and screw can be used, and this technical solution does not limit this.

[0039] like Figure 4 As shown, the other end of the top rod 422 is rotatably connected to the connecting plate 423, and the base 1 is also rotatably connected to the handle 424. The middle part of the handle 424 is rotatably connected to the end of the connecting plate 423 away from the top rod 422.

[0040] As an optional implementation of this utility model, by further defining the clamp 42, after the quality inspector places the copper busbar A, they only need to turn the handle 424 to drive the push rod 422 to slide, causing the clamp 421 to clamp the copper busbar A. When the handle is released, the push rod 422 will not slide naturally, ensuring stable clamping of the copper busbar A. Of course, this technical solution actually constitutes a quick clamp structure, such as the quick clamp of model DEMA-304C, which is prior art, and this technical solution will not elaborate on it further.

[0041] like Figure 1 As shown, the limiting mechanism 4 includes a reference block 43 slidably connected to the base 1. The reference block 43 is located between the length measuring mechanism 5 and the abutment block 321, and the sliding direction of the reference block 43 is aligned with the sliding direction of the abutment block 321.

[0042] As an optional implementation of this utility model, when the fixture 3 slides on the slide rail 2, the abutment block 321 contacts the reference block 43, causing the reference block 43 to slide on the base 1 according to the actual displacement of each abutment block 321. The reference block 43 only moves along the extension and retraction direction of the ejector pin 511, avoiding the problem of direct contact between the abutment block 321 and the ejector pin 511, which could easily lead to an impact and prevent damage to the dial indicator 51. Therefore, the reference block 43 in this technical solution mainly plays the role of displacement transmission. Preferably, the end of the reference block 43 near the abutment block 321 is arc-shaped to avoid two adjacent abutment blocks 321 colliding with the reference block 43 when passing by it in sequence, which would prevent the reference block 43 from reflecting the actual displacement of the abutment block 321.

[0043] The working principle and usage process of this utility model are as follows: After selecting the copper busbar A to be tested from a batch of copper busbars A, the selected copper busbar A is placed on the placement table 31. The fixed position of the positioning block 41 is adjusted according to the length of the copper busbar A so that the positioning block 41 contacts the copper busbar A, and the screw 412 is tightened. Then, the handle 424 is turned so that the chuck 421 presses against the side of the copper busbar A. The reference block 43 and the dial indicator 51 are configured and zeroed. By rotating the screw 211, the fixture 3 is pushed to move on the slide rail 2. When the abutment block 321 passes the reference block 43, the other screw 211 is tightened to clamp the fixture 3 on the slide rail 2. At this time, the reading is taken, which is the length data of the current side tooth A1. By turning the two screws 211, the readings of all abutment blocks 321 are completed, thereby completing the collection of the length data of each side tooth A1 to check whether the length of the side tooth A1 on the copper busbar A to be tested meets the production standard.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
