Description

Technical Field

[0001] This utility model belongs to the field of copper busbar testing technology, and relates to a tool, particularly a copper busbar tool. Background Technology

[0002] Copper busbars, also known as copper busbars, are made of copper and serve to transmit current and connect electrical equipment in circuits. Special-shaped copper busbars are a type of copper busbar that, compared to commonly used copper busbars, have cross-sectional shapes that are not rectangular but come in various forms, including "U"-shaped, "T"-shaped, trapezoidal, and polygonal shapes.

[0003] A search revealed a copper busbar inspection fixture in Chinese patent literature [Application No.: 202021341370.9; Publication No.: CN212274797 U]. This fixture comprises a copper busbar body, a plurality of first mounting holes distributed along a first direction on the body, and a plurality of second mounting holes distributed along a second direction on the body. The fixture includes: a base plate; a support block fixedly mounted on the base plate; a first positioning component comprising a first body mounted on the base plate and a plurality of first positioning posts distributed along the first direction on the first body for positioning the first mounting holes; and a second positioning component comprising a second body mounted on the base plate and a plurality of second positioning posts distributed along the first direction on the second body for positioning the second mounting holes. This utility model's copper busbar inspection fixture achieves rapid inspection of copper busbar products by combining the support block, the first positioning component, and the second positioning component, thus ensuring the quality of the copper busbar products.

[0004] Although the support block, first positioning component, and second positioning component disclosed in this patent enable rapid inspection of copper busbar products and ensure the quality of copper busbar products, they cannot adjust the aperture and hole spacing of the inspection component on the inspection fixture. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in the existing technology by proposing a copper busbar inspection fixture. The technical problem to be solved by this utility model is: how to achieve the adjustment of the hole diameter and hole spacing of the components for inspecting copper busbars on the fixture according to the required standards.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A copper busbar inspection fixture includes a mounting plate and a copper busbar body. A placement block is fixed on the mounting plate. A slot is opened on the placement block. A tension block is slidably connected in the slot. A fixing mechanism is provided between the placement block and the tension block. A fixing plate is fixed on the placement block. Two positioning posts are slidably connected on both the fixing plate and the tension block. A second positioning post is slidably connected in the first positioning post.

[0008] The working principle of this utility model is as follows: the stretching block is pulled out to the required length according to the length of the copper busbar body, and the stretching block is fixed by the fixing mechanism. The distance between the two positioning posts is adjusted according to the required testing standard. Then, positioning post one or positioning post two is selected according to the hole diameter standard. The copper busbar body is placed on the placement block and the stretching block, and the hole diameter and hole spacing of the copper busbar are tested.

[0009] Both the fixing plate and the tensioning block are provided with sliding grooves. A bidirectional threaded rod is rotatably connected in the sliding groove. A slider is threadedly connected to the bidirectional threaded rod. The slider is fixedly connected to the positioning post.

[0010] With the above structure, by installing a bidirectional threaded rod, the rotation of the threaded rod causes the two positioning posts to move in corresponding directions, thereby allowing the distance between the two positioning posts on the inspection fixture to be adjusted as needed to detect the distance between the copper busbar holes.

[0011] The fixing mechanism includes a fixing port on the placement block, and the stretching block has multiple positioning slots. The fixing port and the positioning slots are connected by a fixing rod.

[0012] By adopting the above structure and installing a fixing rod, the stretching block can be stretched according to different copper busbar lengths and positioned by the fixing rod. The length of the stretching block can be adjusted, which facilitates the inspection of the copper busbar and prevents errors.

[0013] The first positioning post has a circular groove, and the inner wall of the circular groove has two annular grooves. The two annular grooves are connected by a straight groove. The outer wall of the second positioning post has two protrusions.

[0014] Using the above structure, by opening an annular groove and installing a protrusion, when the small-diameter positioning post two is needed to detect the diameter of the copper busbar, the protrusion on the positioning post two is rotated in the annular groove at the front end of the positioning post one to the position corresponding to the straight groove, pulled out and rotated in the annular groove at the rear end, offset from the straight groove, thus fixing the positioning post two and preventing the positioning post two from retracting into the positioning post one during the detection process.

[0015] A rotating rod extending from a sliding groove is fixed on the bidirectional threaded rod, and a knob is fixed on the rotating rod.

[0016] By using the above structure, a rotating rod is installed, and by rotating the rotating rod, the bidirectional threaded rod is driven to rotate, thereby adjusting the distance between the two positioning pins.

[0017] Compared with existing technologies, this copper busbar inspection fixture has the following advantages:

[0018] 1. Pull the stretching block to the required length according to the length of the copper busbar body. Fix the stretching block with the fixing mechanism. Adjust the distance between the two positioning posts according to the required testing standards. Then select positioning post one or positioning post two according to the hole diameter standard. Place the copper busbar body on the placement block and the stretching block, and test the hole diameter and hole spacing of the copper busbar.

[0019] 2. By installing a bidirectional threaded rod, the rotation of the threaded rod causes the two positioning pins to move in corresponding directions, thereby adjusting the distance between the two positioning pins on the inspection fixture to check the distance between the copper busbar holes as needed.

[0020] 3. By opening an annular groove and installing a protrusion, when the small-diameter positioning post 2 is needed to test the diameter of the copper busbar, the protrusion on the positioning post 2 is rotated in the annular groove at the front end of the positioning post 1 to the position corresponding to the straight groove, pulled out and rotated in the annular groove at the rear end, offset from the straight groove, thus fixing the positioning post 2 and preventing the positioning post 2 from retracting into the positioning post 1 during the testing process.

[0025] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0026] like Figures 1-3 As shown, this copper busbar inspection fixture includes a mounting plate 1 and a copper busbar body 14. A placement block 2 is fixed on the mounting plate 1. A slot 3 is opened on the placement block 2. A tension block 4 is slidably connected in the slot 3. A fixing mechanism is provided between the placement block 2 and the tension block 4. A fixing plate 5 is fixed on the placement block 2. Two positioning posts 6 are slidably connected on both the fixing plate 5 and the tension block 4. A second positioning post 7 is slidably connected in the positioning post 6.

[0027] Pull the stretching block 4 to the required length according to the length of the copper busbar body 14, fix the stretching block 4 through the fixing mechanism, adjust the distance between the two positioning posts 6 according to the required testing standards, and select positioning post 6 or positioning post 7 according to the hole diameter standard. Place the copper busbar body 14 on the placement block 2 and the stretching block 4 to test the hole diameter and hole spacing of the copper busbar.

[0028] Both the fixed plate 5 and the tension block 4 are provided with a sliding groove 8. A bidirectional threaded rod 9 is rotatably connected in the sliding groove 8. A slider 10 is threadedly connected to the bidirectional threaded rod 9. The slider 10 is fixedly connected to the positioning post 6.

[0029] Using the above structure, by installing the bidirectional threaded rod 9, the rotation of the threaded rod causes the two positioning pins 6 to move in corresponding directions, thereby adjusting the distance between the two positioning pins 6 on the inspection fixture to detect the distance between the copper busbar holes as needed.

[0030] The fixing mechanism includes a fixing port 11 opened on the placement block 2, and multiple positioning grooves 12 opened on the tension block 4. The fixing port 11 and the positioning grooves 12 are connected by a fixing rod 13.

[0031] With the above structure, by installing the fixing rod 13, the stretching block 4 can be stretched according to different copper busbar lengths and positioned by the fixing rod 13. The length of the stretching block 4 can be adjusted, which facilitates the inspection of the copper busbar and prevents errors.

[0032] The positioning post 6 has a circular groove 15, and two annular grooves 16 are formed on the inner wall of the circular groove 15. The two annular grooves 16 are connected by a straight groove 17. Two protrusions 18 are fixed on the outer wall of the positioning post 7.

[0033] With the above structure, by opening the annular groove 16 and installing the protrusion 18, when the small-diameter positioning post 2 7 is needed to detect the diameter of the copper busbar, the protrusion 18 on the positioning post 2 7 is rotated in the annular groove 16 at the front end of the positioning post 1 6 to the position corresponding to the straight groove 17 and pulled out to rotate in the annular groove 16 at the rear end, offset from the straight groove 17, thereby fixing the positioning post 2 7 and preventing the positioning post 2 7 from retracting into the positioning post 1 6 during the detection process.

[0034] A rotating rod 19 extending from a sliding groove 8 is fixed on a bidirectional threaded rod 9, and a knob 20 is fixed on the rotating rod 19.

[0035] By using the above structure, the rotating rod 19 is installed and rotated to drive the bidirectional threaded rod 9 to rotate, thereby adjusting the distance between the two positioning pins 6.

[0036] The working principle of this utility model is to pull the stretching block 4 to the required length according to the length of the copper busbar body 14, and then insert the fixing rod 13 into the fixing port 11 and the positioning groove 12 for fixing. When it is necessary to use the positioning post 2 with a small diameter for testing, the protrusion 18 on the positioning post 2 7 is rotated in the annular groove 16 at the front end of the positioning post 1 6 to the position corresponding to the straight groove 17, and then pulled out and rotated in the annular groove 16 at the rear end, offset from the straight groove 17. By rotating the rotating rod 19, the two positioning posts 1 6 are slidably moved in the corresponding directions, and the copper busbar body 14 is placed on the placement block 2 and the stretching block 4 to test the diameter and hole spacing of the copper busbar.

[0037] In summary, by using fixed post one and fixed post two, the function of adjusting the component hole diameter and hole spacing of the copper busbar on the inspection fixture can be realized according to the required standards.

[0038] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
