Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid batteries, and in particular relates to a multifunctional terminal torque testing tool. Background Art

[0002] Valve-regulated lead-acid battery terminals are the external input and output interfaces of the battery and play a very important role in the use of the battery. The common L-shaped terminal consists of a cylindrical terminal head with threads and a connecting piece for connecting to the inside of the battery. As an important structure for external connection, the stability and reliability of the terminal head thread are particularly important. The thread detection requirements must meet certain torque requirements. The terminal needs to be fixed during the terminal torque detection process. Because the terminal is usually small, the general method of fixing may cause inaccurate test results and cause certain damage to the thread.

[0003] In the existing lead-acid battery terminal detection and fixing method, the terminal is directly fixed on a bench vise, and then a torque wrench is used to screw into the internal thread of the terminal for torque detection. Usually, this method requires a bench vise to directly clamp the terminal to fix the terminal. However, since the clamping force of the bench vise cannot be controlled during the tightening process, when the clamping force is too small, the terminal is easy to fall out during the test. When the clamping force is too large, the bench vise is easy to damage the terminal and even destroy the thread, affecting the detection data. Furthermore, since the number of terminal detections is usually large, each detection requires switching the terminal by loosening or tightening the bench vise, which is inefficient.

[0028] like Figures 1 to 5 As shown, a multifunctional terminal torque testing tool is used for torque testing of multiple battery terminals, wherein the battery terminal 1 includes a connecting piece 11 for cooperating with the terminal pole and a connecting column 12 for connecting an external power cord when the battery is in use, the connecting piece 11 is provided with a positioning hole 13 cooperating with the battery terminal pole, and the top surface of the connecting column 12 has a threaded hole 14.

[0029] The multifunctional terminal torque test tool of the present application comprises a clamping base 2, a terminal fixing base 3 and a terminal opening and closing clamp 4. The clamping base 2 is used to be clamped and fixed on a bench vise 7 when in use.

[0030] The terminal fixing seat 3 is arranged on the top surface of the clamping base 2. The terminal fixing seat 3 can be designed as an integral part with the clamping base 2, or can be designed as a separate body and then detachably installed and fixed together. Preferably, the clamping base 2 and the terminal fixing seat 3 are designed as separate bodies and assembled and fixed by bolts 6. Figure 2As shown, the clamping base 2 is provided with a through fixing hole, and the terminal fixing seat 3 is provided with a corresponding threaded mounting hole. The bolt 6 passes through the fixing hole and cooperates with the threaded mounting hole on the terminal fixing seat 3 to fix the clamping base 2 and the terminal fixing seat 3. This split design method is relatively simple to manufacture both the terminal fixing seat 3 and the clamping base 2. On the other hand, when one of them is damaged or needs to be replaced for other reasons, part of it can be simply replaced without replacing the entire thing.

[0031] The top surface of the terminal fixing seat 3 is provided with a terminal fixing position, which includes a fixing hole 31 for accommodating the connecting column 12 during testing, and a fixing column 32 for the positioning hole 13 to be inserted and fixed.

[0032] In a preferred embodiment, at least two terminal fixing positions are provided on the top surface of the terminal fixing seat 3, and the sizes of the fixing holes 31 and the fixing columns 32 are different between different terminal fixing positions. The fixing holes 31 and the fixing columns 32 of different sizes are used for use with terminals of different specifications.

[0033] In a preferred embodiment, the top surface of the terminal fixing seat 3 is provided with two rows of terminal fixing positions, and each row of terminal fixing positions is provided with at least two terminal fixing positions. In the structure shown in the figure, there are a total of two rows of terminal fixing positions, and each row of terminal fixing positions is provided with 4 terminal fixing positions, so as to be suitable for terminals of different specifications. Among them, the outer periphery of the fixing column 32 of some terminal fixing positions is also provided with a circle of sinking grooves, so as to be suitable for the design of the concave connection piece of some terminals near the positioning hole.

[0034] In order to make the terminal 1 easy to rotate during the detection process after the positioning hole 13 of the terminal 1 is matched with the fixing column 32, the terminal fixing position has a first receiving groove 33 for receiving the connecting piece 11, and the fixing column 32 is arranged on the bottom surface of the first receiving groove 33. Therefore, after the terminal 1 is placed in the terminal fixing position, the side wall of the connecting piece 11 cannot rotate horizontally due to the side wall limit of the first receiving groove 33.

[0035] One end of the terminal opening and closing clamp 4 is hinged to the terminal fixing seat 3. Two hinge seats 41 are respectively arranged on both sides of one end of the terminal opening and closing clamp 4, and the edge of the terminal fixing seat 3 is provided with a second receiving groove 34 for receiving the hinge seat 41, and the hinge seat 41 is hinged to the terminal fixing seat 3 through the rotating shaft 5.

[0036] The terminal opening and closing clamp 4 has an open state in which the terminal fixing position is exposed when it is opened, and a closed state in which the connecting piece 11 is covered to prevent the terminal 1 from falling out of the terminal fixing position during the detection process.

[0037] In the structure shown in the figure, there are two rows of terminal fixing positions, so the terminal opening and closing clamps 4 include two, which are respectively arranged on one side of the terminal fixing seat 3 and are used to cooperate with one row of terminal fixing positions.

[0038] like Figure 5 As shown, when the utility model multifunctional terminal torque test tool is used, it is first clamped and fixed on the bench vise 7 by the clamping base 2, and the terminal opening and closing clamp 4 is rotated to make the terminal opening and closing clamp 4 in an open state, and then the terminal 1 of the battery to be tested is placed in the terminal fixing position of a suitable size, so that the connecting column 12 in the terminal 1 is placed in the fixing hole 31 of the terminal fixing position, and the positioning hole 13 is fixed on the fixing column 32 through a sleeve, and then the terminal opening and closing clamp 4 is rotated to make the terminal opening and closing clamp 4 in a covered state, and then the terminal torque test is performed. After the test is completed, if the terminal needs to be replaced, it is only necessary to rotate the terminal opening and closing clamp 4 to make the terminal opening and closing clamp 4 in an open state, and then the original terminal can be taken out and a new terminal can be put in. Of course, multiple terminals can also be put in at the same time, and only the terminal fixing position is sufficient, and then after all the tests are completed at one time, the new terminal to be tested can be replaced.

[0039] The utility model multifunctional terminal torque test tool is clamped and fixed on the bench vise through the clamping base. The bench vise does not directly act on the terminal and will not cause damage to the terminal. During the terminal inspection process, when the terminal needs to be replaced, there is no need to repeatedly open and close the bench vise, but only need to open and close the terminal opening and closing clamp to take and place the replacement terminal, which is easy to operate and does not damage the terminal. The fixing holes and fixing columns on the terminal fixing seat are respectively fixed with the connecting columns and positioning holes of the terminal, and further covered with the terminal opening and closing clamp, so that the terminal is firmly and stably fixed.
