Description

Technical Field

[0001] This utility model relates to the field of inspection tool manufacturing technology, specifically to a new energy hard copper bar inspection tool. Background Technology

[0002] Hard copper bars are commonly used conductive components in battery equipment. During and after the processing of hard copper bars, they need to be inspected to meet the processing requirements. The traditional method is to inspect them manually, but this method is inefficient and time-consuming.

[0003] Traditional inspection tools cannot complete all measurements on a single tool at once. Since rigid copper bar structural components contain multiple bending surfaces, traditional measurement techniques can only fix a single positioning reference surface of the rigid copper bar structural component. Furthermore, the rigid copper bar structural component cannot be well fixed during measurement, which can easily lead to large measurement errors, increase the difficulty of inspection for inspectors, and make the process more time-consuming. Therefore, traditional rigid copper bar inspection tools have shortcomings in use and need to be improved.

[0004] In summary, there is an urgent need to develop a new type of hard copper inspection tool for new energy applications. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a new energy hard copper bar inspection tool to solve the deficiencies of the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A new energy hard copper bar inspection tool includes an inspection tool base. A positioning reference block is provided on the top of the inspection tool base. The top of the positioning reference block includes a first positioning reference surface and a second positioning reference surface adapted to the contour of the hard copper bar structure. The first positioning reference surface on the positioning reference block is provided with at least one locking member, which fixes the hard copper bar structure to the first positioning reference surface of the positioning reference block. The second positioning reference surface on the positioning reference block is provided with at least one clamping assembly, which fixes the hard copper bar structure to the second positioning reference surface of the positioning reference block.

[0008] Furthermore, the first positioning reference surface is provided with a screw hole, and the locking member is connected in the screw hole. The right-angled edge of the first positioning reference surface on the positioning reference block that contacts the hard copper bar structural member is rounded.

[0009] Furthermore, the second positioning reference surface is provided with a recessed groove, and the recessed groove is provided with a diamond-shaped positioning pin and a tapered positioning pin. The diamond-shaped positioning pin is connected from the top of the positioning reference block to the hole of the positioning reference block, and the tapered positioning pin is embedded inside the measuring positioning reference block, with the top end of the tapered positioning pin protruding from the surface of the positioning reference block.

[0010] Furthermore, the top of the fixture base is also provided with a pin hole detection block one and a pin hole detection block two. The pin hole detection block one and the pin hole detection block two are respectively located on one side of the positioning reference block. The panels of the pin hole detection block one and the pin hole detection block two have through holes. A detection pin is connected in the through hole. A nut is connected to the end of the detection pin away from the through hole. A return spring is sleeved on the outside of the detection pin. One end of the return spring abuts against the nut and the other end abuts against the pin hole detection block.

[0011] Furthermore, the panels of the pin hole detection block one and the pin hole detection block two are marked with outline marking lines.

[0012] Furthermore, this new energy hard copper bar inspection tool also includes a go / no-go gauge for identifying the surface contour and height of the hard copper bar structural component. The base of the inspection tool is provided with a diamond-shaped positioning pin holder and a go / no-go gauge holder.

[0014] A new energy hard copper bar inspection tool is provided. A positioning reference block is set on the base of the tool. The top of the positioning reference block includes a first positioning reference surface and a second positioning reference surface adapted to the contour of the hard copper bar structure. The first positioning reference surface on the positioning reference block is provided with at least one locking element, which fixes the hard copper bar structure to the first positioning reference surface of the positioning reference block. The second positioning reference surface on the positioning reference block is provided with at least one clamping assembly, which fixes the hard copper bar structure to the second positioning reference surface of the positioning reference block. This allows for stable fixation of the hard copper bar structure, providing a fundamental guarantee for subsequent measurement items, solving the problem of measurement errors, reducing the difficulty and time consumption of inspection for inspectors, and improving measurement efficiency and stability.

Detailed Implementation

[0021] 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.

[0022] See Figures 1-5 As shown, this utility model provides a technical solution: a new energy hard copper bar inspection tool, including a tool base 1, a positioning reference block 2 on the top of the tool base 1, and a first positioning reference surface 20 and a second positioning reference surface 21 adapted to the contour of the hard copper bar structural component 3. The first positioning reference surface 20 on the positioning reference block 2 is provided with at least one locking member 4, which fixes the hard copper bar structural component 3 to the first positioning reference surface 20 of the positioning reference block 2. The second positioning reference surface 21 on the positioning reference block 2 is provided with at least one clamping assembly 5, which fixes the hard copper bar structural component 3 to the second positioning reference surface 21 of the positioning reference block 2. This allows the hard copper bar structural component to be stably fixed, providing a basic guarantee for subsequent measurement items, solving the problem of measurement errors, reducing the difficulty and time consumption of inspection for inspectors, and improving measurement efficiency and stability.

[0023] The first positioning reference surface 20 is provided with a screw hole, and a locking member 4 is connected inside the screw hole. The locking member 4 specifically includes a screw section and a pressing head located at the top of the screw section. The screw section on the locking member 4 is connected to the screw hole of the positioning reference block 2. The pressing head presses against the horizontal surface of the hard copper bar structure 3. The downward stroke of the locking member 4 can be adjusted according to the actual thickness of the hard copper bar structure 3. The clamp assembly 5 specifically includes a support 50 and a clamp joint 51 located on the support 50. A pressure roller 52 is provided at the front end of the clamp joint 51. The pressure roller 52 applies clamping force to fix the hard copper bar structure 3 to the positioning reference block 2. The pressure roller 52 can be adjusted in height according to the actual thickness of the hard copper bar structure 3 by adjusting the clamp joint 51 to meet the pressing requirements. The right-angled edge of the first positioning reference surface 20 on the positioning reference block 2 that contacts the hard copper bar structure 3 is rounded. The rounded corners reduce the gap between the hard copper bar structure 3 and the positioning reference block 2, allowing it to be better fixed to the positioning reference block 2.

[0024] See Figure 3 As shown, the second positioning reference surface 21 is provided with a recessed groove 22, which is equipped with a rhomboid positioning pin 6a and a tapered positioning pin 6b. The rhomboid positioning pin 6a is connected from above to the hole of the positioning reference block 2, and the tapered positioning pin 6b is embedded inside the measuring positioning reference block 2, with its top protruding from the surface of the positioning reference block 2. When positioning the hard copper bar structural component 3, the hole 3a of the hard copper bar structural component 3 is engaged with the tapered positioning pin 6b, and then the rhomboid positioning pin 6a is connected to the hole 3b of the hard copper bar structural component 3 and the hole of the positioning reference block 2, which further positions the hard copper bar structural component 3 and prevents it from rotating. The rhomboid positioning pin 6a and the tapered positioning pin 6b also serve to identify whether the relative positions of the holes of the hard copper bar structural component 3 meet the requirements.

[0025] The top of the inspection fixture base 1 is also equipped with a pin hole detection block 7 and a pin hole detection block 8. The pin hole detection blocks 7 and 8 are respectively located on one side of the positioning reference block 2. Through holes 12 are formed on the panels of the pin hole detection blocks 7 and 8, and a detection pin 9 is connected inside the through hole 12. A nut 10 is connected to the end of the detection pin 9 away from the through hole. A return spring 11 is sleeved on the outside of the detection pin 9, with one end abutting against the nut 10 and the other end abutting against the pin hole detection block. By pushing the detection pin 9 towards the hard copper bar structure 3, if the detection pin 9 can smoothly pass through the round hole on the hard copper bar structure 3, it indicates that the opening position of the round hole on the hard copper bar structure 3 meets the requirements. The detection pin 9 identifies whether the relative position of the round hole on the hard copper bar structure 3 meets the requirements. Outline marking lines 13 are engraved on the panels of the pin hole detection blocks 7 and 8 to identify the outline of the hard copper bar structure 3, facilitating the inspector to quickly and accurately locate the corresponding position.

[0026] SeeFigures 3-4 As shown, this new energy hard copper bar inspection tool also includes a go / no-go gauge 14, used to identify the surface contour and height of the hard copper bar structural component 3. The inspection tool base 1 is provided with a diamond-shaped positioning pin clamp 15 and a go / no-go gauge clamp 16. The inspection tool base 1 is provided with a handle 17 to facilitate the transfer and handling of the entire inspection tool.

[0027] In use, the rigid copper bar structure 3 is placed on the positioning reference block 2 and aligned with the first positioning reference surface 20 and the second positioning reference surface 21. When positioning the rigid copper bar structure 3, the hole 3a of the rigid copper bar structure 3 is engaged with the tapered positioning pin 6b, and then the diamond positioning pin 6a is connected to the hole 3b of the rigid copper bar structure 3 and the hole of the positioning reference block 2. This further positions the rigid copper bar structure 3 and prevents it from rotating. The diamond positioning pin 6a and the tapered positioning pin 6b simultaneously identify whether the relative positions of the holes on the rigid copper bar structure 3 meet the requirements. By pushing the detection pin 9 towards the rigid copper bar structure 3, if the detection pin 9 can smoothly pass through the round hole 3c on the rigid copper bar structure 3, it indicates that the opening position of the round hole 3c on the rigid copper bar structure 3 meets the requirements. The detection pin 9 identifies whether the relative positions of the round hole 3c on the rigid copper bar structure 3 meet the requirements. The surface profile and height of the hard copper bar structural component 3 can then be inspected using the go / no-go gauge 14.
