Description

Technical Field

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

[0002] With the development of the times, modern automobiles are gradually shifting from engines to new energy sources. Currently, the most mature technology for new energy vehicles utilizes batteries to drive motors. The connection between battery modules typically requires the use of highly conductive rigid aluminum alloy bars. In the manufacturing sector, it is necessary to inspect the manufactured rigid aluminum alloy bar components. Traditional inspection tools cannot complete all measurements on a single tool at once. Furthermore, because rigid aluminum alloy bar components contain multiple bending surfaces, traditional measurement techniques can only fix a single positioning reference surface of the component. Moreover, the inability to properly fix the component during measurement can easily lead to large measurement errors, increasing the difficulty and time required for inspection. Therefore, traditional rigid aluminum alloy bar inspection tools have shortcomings and need improvement.

[0003] In summary, there is an urgent need to develop a new type of hard aluminum inspection tool. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a new energy hard aluminum bar detector, which solves the deficiencies of traditional hard aluminum bar detectors in use.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A new energy hard aluminum bar inspection tool includes an inspection tool base, on which a measuring positioning block is provided. The top of the measuring positioning block includes a reference surface one and a reference surface two adapted to the contour of the hard aluminum bar structural component. The reference surface one on the measuring positioning block is provided with a diamond-shaped positioning pin and a tapered positioning pin. The diamond-shaped positioning pin is inserted into a hole in the measuring positioning block from the top. The tapered positioning pin is embedded inside the measuring positioning block. A spring is provided at the bottom of the tapered positioning pin, which causes the top of the tapered positioning pin to protrude from the surface of the measuring positioning block. The reference surface two on the measuring positioning block is provided with at least two sets of circular detection pins, which are diagonally distributed. Clamping assemblies are symmetrically arranged on both sides of the measuring positioning block. The clamping assemblies are mounted on the inspection tool base and apply clamping force to fix the hard aluminum bar structural component to the measuring positioning block.

[0007] Furthermore, there is a height difference between the first reference surface and the second reference surface, and the junction of the two reference surfaces is an arc-shaped transition structure.

[0008] Furthermore, the clamp assembly includes a clamp support, a clamp joint, and a clamping block. The clamp support is fixed on the fixture base. The clamp joint is provided on the top of the clamp support. The clamping block is provided at the front end of the clamp joint. The clamping block applies clamping force to fix the hard aluminum bar structure to the measuring positioning block.

[0009] Furthermore, a T-shaped sleeve is embedded inside the measuring positioning block. The top of the T-shaped sleeve is flush with or protrudes from the reference surface. The T-shaped sleeve has a through hole that is compatible with the diamond-shaped positioning pin and the tapered positioning pin.

[0010] Furthermore, the new energy hard aluminum bar inspection tool also includes a go / no-go gauge, used to identify whether the surface contour and height of the hard aluminum bar structural component meet the requirements. The inspection tool base is provided with a diamond-shaped positioning pin clamp, a circular detection pin clamp, and a go / no-go gauge clamp.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] A new energy hard aluminum bar inspection tool is provided. A measuring and positioning block is designed on the base of the tool. The top of the measuring and positioning block includes two reference surfaces, one and two, adapted to the contour of the hard aluminum bar structure. Multiple corresponding holes on the hard aluminum bar structure are positioned and measured using diamond-shaped positioning pins, tapered positioning pins, and two sets of circular detection pins. A clamping assembly applies clamping force to fix the hard aluminum bar structure onto the measuring and positioning block. The clamping assembly is adjustable to accommodate hard aluminum bar structures of different sizes and thicknesses. Using this tool reduces the inspection difficulty for inspectors and improves measurement efficiency and stability. Attached Figure Description

[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] See Figure 1-6 As shown, this utility model provides a technical solution: a new energy hard aluminum bar inspection tool, including an inspection tool base 1, a measuring positioning block 2 is provided on the inspection tool base 1, the top of the measuring positioning block 2 includes a reference surface 20 and a reference surface 21 adapted to the contour of the hard aluminum bar structural component 12, the reference surface 20 on the measuring positioning block 2 is provided with a rhomboid positioning pin 3 and a tapered positioning pin 4, the rhomboid positioning pin 3 is connected to the hole of the measuring positioning block 2 from the top of the measuring positioning block 2, the tapered positioning pin 4 is embedded in the measuring positioning block 2, the bottom of the tapered positioning pin 4 is provided with a spring, the spring makes the top of the tapered positioning pin 4 protrude from the surface of the measuring positioning block 2, the reference surface 21 on the measuring positioning block 2 is provided with at least two sets of circular detection pins 5, the two sets of circular detection pins 5 are diagonally distributed, clamping assemblies 6 are symmetrically arranged on both sides of the measuring positioning block 2, the clamping assemblies 6 are set on the inspection tool base 1, the clamping force is applied by the clamping assemblies 6 to fix the hard aluminum bar structural component 12 to the measuring positioning block 2. This new energy hard aluminum bar inspection tool features a measuring and positioning block on its base. The top of the measuring and positioning block includes a reference surface 20 and a reference surface 21 that conform to the contour of the hard aluminum bar structural component. Multiple corresponding holes on the hard aluminum bar structural component 12 are positioned and measured using diamond-shaped positioning pins 3, tapered positioning pins 4, and two sets of circular detection pins 5. A clamping force is applied by a clamping assembly 6 to fix the hard aluminum bar structural component 12 onto the measuring and positioning block 2. The clamping assembly 6 can be adjusted to accommodate the fixing requirements of hard aluminum bar structural components of different sizes and thicknesses. Using this inspection tool reduces the inspection difficulty for inspectors and improves measurement efficiency and stability.

[0022] There is a height difference between reference surface 1 20 and reference surface 21, and the junction of the two reference surfaces is an arc-shaped transition structure, which allows the hard aluminum bar structure 12 to be better placed on the measuring positioning block 2, thereby reducing errors.

[0023] See Figure 4-5 As shown, the clamp assembly 6 includes a clamp support 60, a clamp joint 61, and a clamping block 62. The clamp support 60 is fixed on the fixture base 1. The clamp joint 61 is located on the top of the clamp support 60, and the clamping block 62 is located at the front end of the clamp joint 61. The clamping block 62 applies clamping force to fix the rigid aluminum bar structure 12 to the measuring positioning block 2. An anti-slip layer can be provided on the contact surface of the clamping block 62 to enhance the fixing stability and prevent measurement deviation caused by the movement of the rigid aluminum bar structure 12. The symmetrical arrangement of the clamp assembly 6 ensures that the rigid aluminum bar structure 12 is subjected to uniform force. The clamping block 62 can adjust the clamping angle through the clamp joint 61 to adapt to the fixing requirements of rigid aluminum bar structure 12 with different sizes and thicknesses.

[0024] A T-shaped sleeve 7 is embedded inside the measuring positioning block 2. The top of the T-shaped sleeve 7 is flush with or protrudes from the reference surface 20. The T-shaped sleeve 7 has through holes that fit the rhomboid positioning pin 3 and the tapered positioning pin 4. When positioning the hard aluminum bar structural component 12, the corresponding hole of the hard aluminum bar structural component 12 is engaged with the tapered positioning pin 4, and then the rhomboid positioning pin 3 is connected to the through hole of the T-shaped sleeve 7. This further positions the hard aluminum bar structural component 12 and prevents it from rotating. The rhomboid positioning pin 3 and the tapered positioning pin 4 also serve to identify whether the relative positions of the holes of the hard aluminum bar structural component 12 meet the requirements.

[0025] See Figure 5 As shown, the new energy hard aluminum bar inspection tool also includes a go / no-go gauge 13, used to identify whether the surface contour and height of the hard aluminum bar structural component 12 meet the requirements. The inspection tool base 1 is provided with a diamond-shaped positioning pin clamp 8, a circular detection pin clamp 9, and a go / no-go gauge clamp 10. The inspection tool base 1 is provided with a handle 11 to facilitate the transfer and handling of the entire inspection tool.

[0026] In use, the rigid aluminum bar structure 12 is placed on the measuring positioning block 2 and aligned with reference surface 20 and reference surface 21. When positioning the rigid aluminum bar structure 12, the corresponding hole of the rigid aluminum bar structure 12 is engaged with the tapered positioning pin 4, and then connected to the through hole of the T-sleeve 7 via the diamond positioning pin 3. This further positions the rigid aluminum bar structure 12 and prevents it from rotating. The diamond positioning pin 3 and the tapered positioning pin 4 simultaneously identify whether the relative position of the hole 13a on the rigid aluminum bar structure 12 meets the requirements. Then, the clamping force is applied by the clamping block 62 on the clamp assembly 6 to fix the rigid aluminum bar structure 12 onto the measuring positioning block 2. Two sets of circular detection pins 5 are used to measure the corresponding hole 13b on another horizontal surface of the rigid aluminum bar structure 12, measuring the diameter of the hole penetrating this horizontal surface and whether its positional relationship is correct. Finally, the surface contour and height of the rigid aluminum bar structure 12 can be inspected using the go / no-go gauge 13.
