Description

Technical Field

[0001] This utility model belongs to the field of lead-acid battery manufacturing technology, and relates to a tooling for detecting the taper of lead-acid battery terminals, and more particularly to a detection tooling that achieves rapid and accurate measurement through a hollow design. Background Technology

[0002] Lead-acid battery terminals are typically tapered, and the accuracy of this tapering directly affects the battery's sealing and the reliability of its electrical connections. Traditional testing methods use a split-ring fixture, where two independent rings are installed at different depths on the terminal's tapered surface (e.g., 1mm and 10mm). The taper's quality is indirectly judged by the fit between the rings and the terminal. However, this approach has the following drawbacks:

[0003] 1. Insecure pressing: The collar and the main body of the tooling are separate structures, which can easily cause the collar to shift during measurement due to assembly gaps or vibration, affecting the measurement accuracy;

[0004] 2. Superposition of secondary errors: The two rings need to be processed and calibrated separately, and the cumulative error may lead to deviation in the overall test results;

[0005] 3. Cumbersome operation: It requires changing the ring or adjusting the tooling multiple times, resulting in low efficiency.

[0006] Therefore, an integrated and high-precision detection solution is needed. Utility Model Content

[0007] This utility model provides a lead-acid battery terminal taper detection fixture, which directly measures the diameter of the terminal taper surface through a hollow design, solving the problems of poor pressing, error accumulation, and cumbersome operation of traditional ring fitting fixtures.

[0008] The technical solution of this utility model is: a taper testing fixture for lead-acid battery terminals, characterized in that: it includes a tapered sleeve that mates with the lead-acid battery terminal and a positioning seat that mates with the root of the lead-acid battery terminal; wherein, the upper end and the side of the tapered sleeve are respectively provided with a measuring window and a hollow measuring window; the positioning seat is located at the bottom of the tapered sleeve and is provided with a groove that mates with the root of the lead-acid battery terminal.

[0009] In the technical solution of this utility model, there are two hollowed-out measuring windows, which are symmetrically arranged along the axial direction on the side wall of the conical sleeve; the measuring windows are located at the upper end of the conical sleeve.

[0010] The hollow measurement window described in the technical solution of this utility model is a rectangular hollow window.

[0011] In the technical solution of this utility model, the window size of the hollowed-out measuring window is slightly larger than the diameter tolerance range of the terminal at that location.

[0012] In the technical solution of this utility model, the hollow measuring window is located at a depth of 10mm from the entrance of the conical hole; the measuring window is located at a depth of 1mm from the entrance of the conical hole.

[0013] In the technical solution of this utility model, the top surface of the groove is a reference positioning surface that mates with the reference surface at the root of the lead-acid battery terminal.

[0014] The reference positioning surface described in the technical solution of this utility model is an annular plane.

[0015] The groove described in the technical solution of this utility model is a positioning groove that mates with the root of the lead-acid battery terminal.

[0016] The positioning groove described in the technical solution of this utility model is an annular positioning groove.

[0017] The advantages of this utility model are: 1. Improved accuracy: Direct measurement of the terminal body avoids errors caused by indirect rings, and the accuracy can reach ±0.02mm; 2. Optimized efficiency: No need to replace the rings, a single tooling can complete dual-position detection, improving efficiency by more than 50%; 3. Reduced cost: Simplified structure reduces tooling manufacturing cost by 30% and maintenance cost by 30%.

[0018] This invention has the advantages of simple structure, high detection efficiency and low cost, and is suitable for high-precision batch testing of lead-acid battery terminals. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 4As shown, one embodiment of the lead-acid battery terminal taper detection fixture of this utility model includes a tapered sleeve that mates with the lead-acid battery terminal and a positioning seat that mates with the root of the lead-acid battery terminal, wherein the positioning seat is disposed at the bottom of the tapered sleeve.

[0026] The inner cavity of the tapered sleeve fits into the lead-acid battery terminal. Measuring windows 1-2 and 1-1 are respectively provided on the upper end and side of the tapered sleeve. Measuring window 1-1 is located 10mm from the entrance of the tapered hole, and measuring window 1-2 is located 1mm from the entrance of the tapered hole, which is the annular hole at the upper end, allowing for direct measurement. There are two 1-1 shaped measuring windows, symmetrically arranged axially on the side wall of the tapered sleeve. Both are rectangular shaped windows, with the window size slightly larger than the diameter tolerance of the terminal at that location, ensuring that the probe of the measuring tool (such as a digital caliper) can directly contact the terminal surface. Measuring window 1-2 ensures that the probe of the measuring tool (such as a digital caliper) can directly contact the terminal surface.

[0027] The positioning seat has a groove that mates with the root of the lead-acid battery terminal. The positioning seat is disc-shaped, with the groove opening facing downwards and a circular through-hole at the top communicating with the inner cavity of the conical sleeve. The top surface of the groove is a reference positioning surface 1-3, which is an annular plane and mates with the reference surface at the root of the lead-acid battery terminal. The groove is a positioning groove 1-4, an annular positioning groove that mates with the root of the lead-acid battery terminal. Reference positioning surface 1-3 and positioning groove 1-4 allow for rapid positioning with the reference surface at the root of the battery terminal.

[0028] When using this utility model to detect the taper of lead-acid battery terminals, the diameter of the terminal cone surface is directly measured through the hollow design. The terminal diameter D1 at 10mm is directly measured through the measuring tool in the hollow measuring window 1-1, and the terminal diameter D2 at 1mm is directly measured through the measuring tool in the measuring window 1-2. Then, the taper of the lead-acid battery terminal is obtained through the taper calculation formula V=(D2-D1) / 9.

[0029] During the use of this fixture, the reference positioning surface 1-3 and the positioning groove 1-4 can be matched with the root of the lead-acid battery terminal to ensure the accuracy of the measurement.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
