Description

Technical Field

[0001] This application relates to the field of aluminum busbar inspection technology, and in particular to an inspection tool for bending aluminum busbars. Background Technology

[0002] Various components inside a car require wiring harnesses for connection. However, these harnesses are long and difficult to manage. Therefore, it is necessary to design an aluminum busbar that can guide the car's wiring harnesses to accommodate the internal structure of the car.

[0003] Reference Figure 1 The company disclosed an irregularly shaped aluminum busbar. Because the aluminum busbar is long and thin and easily deformed, its dimensions need to be inspected before it is packaged.

[0004] In the existing technology, measuring tools such as calipers and protractors are commonly used to inspect the specific dimensions of aluminum busbars. However, when it is necessary to process irregular aluminum busbars in batches, it is time-consuming and prone to measurement errors if measuring tools are used to measure the dimensions of each aluminum busbar individually, which reduces the inspection efficiency of irregular aluminum busbars. Summary of the Invention

[0005] To improve the inspection efficiency of irregularly shaped aluminum bars, this application provides a gauge for bending aluminum bars.

[0006] The technical solution for the inspection tool used for bending aluminum strips provided in this application is as follows: A gauge for bending aluminum busbars includes a testing mold with a testing groove, the shape of which is consistent with the shape of the aluminum busbar.

[0007] By adopting the above technical solution, during testing, aluminum bars are placed into the testing tank. If they can be successfully placed into the testing tank, the aluminum bars pass the test; if they cannot be successfully placed into the testing tank, the aluminum bars fail the test. By setting up testing molds and relying on the testing tank to verify the shape of the aluminum bars, the testing steps are simplified, the testing time is shortened, measurement errors are less likely to occur, and the testing efficiency of irregularly shaped aluminum bars is improved.

[0008] Optionally, the testing mold includes a first seat, a second seat, a third seat, a fourth seat, and a fifth seat, with each pair of the first seat, second seat, third seat, fourth seat, and fifth seat being detachably connected. The testing groove passes through the first seat, second seat, third seat, fourth seat, and fifth seat, with the second seat connected to the bottom end of the third seat and the fourth seat connected to the top end of the third seat.

[0009] The above technical solution addresses the issue that the testing mold is too long, occupies a lot of space, and is inconvenient to store. By setting up a first, second, third, fourth, and fifth seat, these seats can be assembled during use, making the storage of the testing mold much easier.

[0010] Optionally, an assembly component is provided between the first and second seats. The assembly component includes a dovetail block, a stop block, a pressure plate, and a locking bolt. The first seat has a dovetail groove, the stop block is connected to the bottom end of the dovetail groove, the dovetail block is connected to the second seat, the dovetail block is inserted into the dovetail groove and is flush with the surface of the first seat, the pressure plate is placed on the surface of the first seat and covers the dovetail block, and the locking bolt passes through the pressure plate and the first seat and is threaded into the first seat. Similarly, the assembly component is provided between the second and third seats, between the third and fourth seats, and between the fourth and fifth seats.

[0011] By adopting the above technical solution, when assembling the first and second seats, the dovetail block is inserted into the dovetail groove and abuts against the stop block. At this time, the dovetail block is flush with the surface of the first seat. Then, the pressure plate is covered and the locking bolt is rotated until the locking bolt presses the pressure plate. The pressure plate applies pressure to the dovetail block, thereby restricting the degree of freedom of the dovetail block, thus realizing the assembly of the first and second seats. Similarly, the assembly between the second and third seats, between the third and fourth seats, and between the fourth and fifth seats can be realized.

[0012] Optionally, the first seat, the second seat, the fourth seat, and the fifth seat all have material-taking grooves on their surfaces. The material-taking grooves are connected to the detection grooves, and the depth of the material-taking grooves is greater than the depth of the detection grooves.

[0013] By adopting the above technical solution, once the aluminum busbar passes the inspection, it needs to be removed. Workers can simply reach into the material-grabbing groove to grab the aluminum busbar, making the operation convenient and quick.

[0014] Optionally, both the second and fifth seats are equipped with a material-picking assembly, which includes a push block, a slide rod, and a return spring. Both the second and fifth seats have a sliding groove, the depth of which is greater than the depth of the detection groove. The length direction of the sliding groove is perpendicular to the length direction of the detection groove. The slide rod is a rectangular rod connected to the push block. The push block slides within the sliding groove via the slide rod. A pushing inclined surface is provided on the side wall of the push block away from the slide rod. Two push blocks are provided, arranged opposite each other, with the reference direction from bottom to top. The distance between the two pushing inclined surfaces gradually increases. A retaining ring is connected to the end of the slide rod away from the push block. The return spring is sleeved on the slide rod and located between the retaining ring and the second seat. Similarly, the material-picking assembly is provided on the fifth seat. During material picking, the pushing inclined surface applies pressure to the aluminum strip.

[0015] By adopting the above technical solution, when picking up the aluminum bar, two push blocks are pushed and move relative to each other. The return spring is compressed, and during this process, the inclined plane is pushed to press the aluminum bar, causing the aluminum bar to tilt up. At this time, the aluminum bar falls into the hands of the worker, thus achieving the effect of picking up the aluminum bar.

[0016] Optionally, both the second and fifth seats are provided with a material removal assembly. The material removal assembly includes a material removal cam, a rotating shaft, and an operating column. The second seat has a rotating groove at the position corresponding to the detection groove. The rotating shaft is rotatably connected to the second seat, with one end located in the rotating groove. The material removal cam is connected to one end of the rotating shaft, and the operating column is connected to the other end of the rotating shaft. Restricting rings are connected to the rotating shaft at positions corresponding to the inner wall of the rotating groove and the outer wall of the second seat. Similarly, the material removal assembly is provided on the fifth seat.

[0017] By adopting the above technical solution, when taking out aluminum bars, the operating column is rotated to make the rotating shaft rotate, which drives the unloading cam to rotate. The unloading cam pushes out the aluminum bars, causing the aluminum bars to leave the detection slot, and then the aluminum bars can be taken out.

[0018] Optionally, the surface of the operating column is provided with anti-slip textured surfaces.

[0019] By adopting the above technical solution, the anti-slip texture is used to increase the friction on the surface of the operating column, making it easier for workers to apply force to operate the column.

[0020] Optionally, support seats can be detachably connected to the bottom walls of both the fourth and fifth seats.

[0021] By adopting the above technical solution, the support base is used to support the fourth or fifth base, so that the fourth and fifth bases remain in a horizontal state.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. During detection, place the aluminum row into the detection tank. In this process, if it can smoothly enter the detection tank, the aluminum row is qualified for detection; if the aluminum row cannot be smoothly placed into the detection tank, the aluminum row is unqualified for detection. By setting up the detection mold and relying on the detection tank to check the shape of the aluminum row, the detection steps of the aluminum row are simplified, the detection time of the aluminum row is shortened, and measurement errors are not likely to occur, improving the detection efficiency of the special-shaped aluminum row; 2. When assembling the first and second seats, insert the燕尾块 (swallowtail block) into the燕尾槽 (swallowtail groove) and抵触挡块 (abut against the stop block). At this time, the swallotail block is flush with the surface of the first seat. Then cover the pressure plate and turn the locking bolt until the locking bolt presses the pressure plate. The pressure plate presses the swallotail block to restrict the freedom degree of the swallotail block, realizing the assembly of the first and second seats. Similarly, the assembly between the second and third seats, the third and fourth seats, and the fourth and fifth seats is realized; 3. When taking the aluminum row, push the two push blocks. The two push blocks move relative to each other, and the return spring is compressed. During this process, the pushing inclined plane presses the aluminum row, causing the aluminum row to tilt up. At this time, the aluminum row falls into the hands of the operator, achieving the effect of taking the aluminum row. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed Implementation

[0031] The following is in conjunction with the appendix Figures 2-7 This application will be described in further detail.

[0032] Embodiment 1 of this application discloses a gauge for bending aluminum strips. (Refer to...) Figure 2 The inspection fixture for bending aluminum strips includes an inspection mold 1, which comprises a first seat 11, a second seat 12, a third seat 13, a fourth seat 14, and a fifth seat 15. Inspection grooves 16 are also provided between the first seat 11, the second seat 12, the third seat 13, the fourth seat 14, and the fifth seat 15, with the second seat 12 corresponding to the bottom end of the third seat 13 and the fourth seat 14 corresponding to the top end of the third seat 13. The inspection grooves 16 conform to the shape of the aluminum strip. Support seats 2 are bolted to the bottom walls of the fourth seat 14 and the fifth seat 15 to improve their structural strength.

[0033] Reference Figure 3 Assembly components 3 are provided between the first seat 11 and the second seat 12, between the second seat 12 and the third seat 13, between the third seat 13 and the fourth seat 14, and between the fourth seat 14 and the fifth seat 15. Each assembly 3 includes a dovetail block 31, a stop block 32, a pressure plate 33, and locking bolts 34. The first seat 11 has several dovetail grooves; in this embodiment, two are used as an example. The stop block 32 is fixedly connected to the bottom end of the dovetail groove. Two pressure blocks are fixedly connected to the second seat 12, inserted into the dovetail groove, and flush with the surface of the first seat 11. The pressure plate 33 covers the space between the dovetail block 31 and the first seat 11. Several locking bolts 34 pass through the pressure plate 33 and the first seat 11; in this embodiment, two are used as an example. The locking bolts 34 are threaded into the first seat 11 and press against the pressure plate 33.

[0034] During assembly, the dovetail block 31 on the second seat 12 is inserted into the dovetail groove until it contacts the stop block 32. Then, the pressure plate 33 is covered, and the locking bolt 34 is rotated until the locking bolt 34 presses the pressure plate 33 to restrict the degree of freedom of the dovetail block 31, thus realizing the assembly of the first seat 11 and the second seat 12. Similarly, the second seat 12 and the third seat 13, the third seat 13 and the fourth seat 14, and the fourth seat 14 and the fifth seat 15 are assembled.

[0035] Reference Figure 1 The first seat 11, the second seat 12, the fourth seat 14 and the fifth seat 15 are all provided with material taking grooves 4, and the detection groove 16 passes through the material taking grooves 4. The bottom wall of the material taking grooves 4 is lower than the bottom wall of the detection groove 16.

[0036] The implementation principle of a gauge for bending aluminum strips in this application embodiment is as follows: During inspection, the worker puts the aluminum strip into the inspection groove 16. If the aluminum strip enters the inspection groove 16 smoothly, the aluminum strip size is qualified. During unloading, the worker puts his hand into the material picking groove 4 to take out the aluminum strip.

[0037] By setting up a testing mold and relying on the testing slot 16 to verify the shape of the aluminum busbar, the testing steps of the aluminum busbar are simplified, the testing time of the aluminum busbar is shortened, and measurement errors are less likely to occur, thus improving the testing efficiency of irregularly shaped aluminum busbars.

[0038] Example 2: The difference between this example and Example 1 is that the aluminum busbar is removed in a different way.

[0039] Reference Figure 4 and Figure 5 Both the second seat 12 and the fifth seat 15 are equipped with a material-picking assembly 5, which includes a push block 51, a slide rod 52, and a return spring 53. The second seat 12 has a sliding groove, through which a detection groove 16 passes. The length direction of the sliding groove is perpendicular to the length direction of the detection groove 16, and the depth of the sliding groove is greater than the depth of the detection groove 16. The slide rod 52 is a rectangular rod, with one end fixedly connected to the push block 51. The push block 51 slides within the sliding groove via the slide rod 52. The push block 51 has a pushing inclined surface. Two push blocks 51 are arranged within the sliding groove, facing each other, with the reference direction from bottom to top. The distance between the two pushing inclined surfaces gradually increases. The other end of the slide rod 52 is fixedly connected to a retaining ring 521. The return spring 53 is sleeved on the slide rod 52 and located between the retaining ring 521 and the second seat 12. Similarly, the material-picking assembly 5 is provided on the fifth seat 15.

[0040] When picking up the material, push the push block 51, compress the reset spring 53, and push the inclined surface to apply pressure to the aluminum strip until the aluminum strip is removed from the detection groove 16. At this time, the aluminum strip can be removed, and the push block 51 moves in the opposite direction under the force of the reset spring 53, returning to the initial position.

[0041] Example 3: The difference between this example and Example 1 is that the aluminum busbar is removed in a different way.

[0042] Reference Figure 6 and Figure 7Both the second seat 12 and the fifth seat 15 are equipped with a material removal assembly 6, which includes a material removal cam 61, a rotating shaft 62, and an operating column 63. The second seat 12 has a rotating groove located within the detection groove 16, with its bottom wall lower than the bottom wall of the detection groove 16. The rotating shaft 62 is rotatably connected to the second seat 12, and a limiting ring is fixedly connected to the rotating shaft 62 at a position corresponding to the side wall of the rotating groove and the outer wall of the second seat 12. The material removal cam 61 is fixedly connected to one end of the rotating shaft 62 and located within the rotating groove. The operating column 63 is fixedly connected to the other end of the rotating shaft 62 and located outside the second seat 12. The surface of the operating column 63 is provided with anti-slip textures 631, which increase the surface friction of the operating column 63.

[0043] When picking up aluminum bars, the operating column 63 is rotated, which drives the rotating shaft 62 to rotate, causing the unloading cam 61 to rotate. The unloading cam 61 pushes out the aluminum bars, causing the aluminum bars to separate from the detection groove 16, thus achieving the effect of picking up aluminum bars.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
