Description

Technical Field

[0001] This utility model belongs to the field of battery terminal testing technology, and in particular relates to a tooling for testing the terminal post holes of automotive batteries. Background Technology

[0002] During battery production and assembly, a high degree of precision is required in the welding quality between the terminals and the posts to ensure the quality of the welding. Therefore, accurately controlling the dimensional accuracy of the terminal post holes is particularly important during terminal production and use.

[0003] Currently, vernier calipers are commonly used to inspect terminal post holes. However, due to the limited space within the post hole, calipers cannot accurately measure the dimensions of the conical surface inside the hole. Therefore, caliper inspection is inaccurate, inefficient, and inconsistent, making it difficult to guarantee that the post hole dimensions meet standard requirements. Therefore, this paper proposes a fixture for inspecting automotive battery terminal post holes to solve this problem. Utility Model Content

[0004] This utility model addresses the problems in the prior art by proposing the following technical solution:

[0005] A tooling fixture for inspecting the terminal post holes of an automotive battery includes a bracket, a connecting shaft fixedly connected to the bracket, and a GO end shaft and an NG end shaft fixedly connected to both ends of the connecting shaft, respectively. A detachable go gauge is installed on the end of the GO end shaft away from the connecting shaft, and the go gauge has two scale lines on its periphery. A no-go gauge is fixedly connected to the end of the NG end shaft away from the connecting shaft, and the no-go gauge has one scale line on its periphery.

[0006] As a preferred embodiment of the above technical solution, the diameter of the end of the go gauge closest to the GO end is greater than the diameter of the other end, the diameter of the end of the no-go gauge closest to the NG end is greater than the diameter of the other end, and is also greater than the diameter of the end of the no-go gauge closest to the NG end, and the diameter of the end of the no-go gauge furthest from the NG end is greater than the diameter of the end of the go gauge furthest from the GO end.

[0007] As a preferred embodiment of the above technical solution, the diameter of the end of the go gauge near the GO end shaft is 14.28, and the diameter of the end away from the GO end shaft is 11.6. The diameter of the end of the stop gauge near the NG end shaft is 14.68, and the diameter of the end away from the NG end shaft is 11.8.

[0008] As a preferred embodiment of the above technical solution, the bracket includes a fixed base, a support frame is fixedly connected to the top of the fixed base, a fixed frame is fixedly connected to the top of the support frame, the connecting shaft is sleeved in the inner ring of the fixed frame, the fixed base has a positioning hole, and the support frame has a through hole.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model pushes the terminal post hole laterally into the go gauge and no-go gauge. If the terminal passes through the go gauge and is located between the two scale lines one, and the no-go gauge does not exceed the scale line two, it is qualified; otherwise, it will be judged as unqualified. The newly designed terminal post hole inspection fixture has a more reasonable and scientific structure, is easier to operate, shortens the inspection time, and improves the inspection accuracy and production efficiency.

[0011] 2. Through practical application, this utility model ensures quality control over the taper performance of the terminal post holes during the production process. It addresses the requirements of the battery assembly end and improves assembly quality. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example

[0019] like Figure 1 , Figure 2 and Figure 3 As shown, a tooling fixture for inspecting the terminal post holes of an automotive battery includes a bracket, a connecting shaft 6 fixedly connected to the bracket, and a GO end shaft 7 and an NG end shaft 10 fixedly connected to both ends of the connecting shaft 6, respectively. A detachable go gauge 8 is installed at the end of the GO end shaft 7 away from the connecting shaft 6, and two scale lines 9 are opened on the periphery of the go gauge 8. A no-go gauge 11 is fixedly connected at the end of the NG end shaft 10 away from the connecting shaft 6, and a scale line 12 is opened on the periphery of the no-go gauge 11.

[0020] It should be noted that the bracket includes a fixed base 1, a support frame 3 is fixedly connected to the top of the fixed base 1, a fixed frame 5 is fixedly connected to the top of the support frame 3, and a connecting shaft 6 is sleeved in the inner ring of the fixed frame 5. The fixed base 1 has a positioning hole 2, and the bolts can be used to fix the fixed base 1 to the operating table through the positioning hole 2 to prevent shaking when testing the terminal pole hole. The support frame 3 has a through hole 4 to reduce the overall weight of the bracket and make the work lighter.

[0021] Specifically, the terminal post hole is pushed laterally into the go gauge 8 and the no-go gauge 11. If the terminal passes through the go gauge 8 and is located between the two scale lines 1-9, and the no-go gauge 11 does not exceed the scale line 2-12, it is considered qualified; otherwise, it will be judged as unqualified. The newly designed terminal post hole inspection fixture has a more reasonable and scientific structure, is easier to operate, shortens the inspection time, and improves the inspection accuracy and production efficiency.

[0022] like Figure 2 and Figure 3 As shown, the diameter of the end of the go gauge 8 near the GO end shaft 7 is greater than the diameter of the other end. The diameter of the end of the stop gauge 11 near the NG end shaft 10 is greater than the diameter of the other end. It is also greater than the diameter of the end of the stop gauge 11 near the NG end shaft 10. The diameter of the end of the stop gauge 11 away from the NG end shaft 10 is greater than the diameter of the end of the go gauge 8 away from the GO end shaft 7.

[0023] like Figure 3 As shown, the diameter of the end of the go gauge 8 near the GO end shaft 7 is 14.28, and the diameter of the end away from the GO end shaft 7 is 11.6. The diameter of the stop gauge 11 near the NG end shaft 10 is 14.68, and the diameter of the end away from the NG end shaft 10 is 11.8.

[0024] It should be noted that, based on the upper and lower dimensional tolerances of the terminal post hole, the range of go and no-go values ​​for the inspection gauge is determined, and a tooling fixture capable of accurately inspecting the dimensions of the terminal post hole is designed. Go gauge 8 represents the lower limit of the upper and lower dimensional tolerances of the post hole; no-go gauge 11 represents the upper limit of the upper and lower dimensional tolerances of the post hole.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
