Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a radial thrust test fixture for pole posts. Background Technology

[0002] Battery terminals are an important component of a battery. They are special structures that serve as the current collector and provide strong corrosion resistance. Battery terminals generally consist of a column body, a base, and a head. Their shape, size, and model need to be designed and manufactured according to different battery types, current requirements, and environmental adaptability. The selection principle for battery terminals is to require materials with high conductivity, good corrosion resistance, dimensional stability, and processing performance. Commonly used materials include metals such as copper, aluminum, and zinc alloys, among which pure copper has the best performance. The processing technology of battery terminals generally adopts processes such as cold extrusion and hot extrusion. Through the pressing and stretching of molds, the metal material is pressed into a cylindrical shape with precise holes and uniform density to facilitate later assembly and use.

[0003] After manufacturing, the pole needs to undergo a thrust test, which involves applying a certain radial force to the pole to determine whether it will bend relative to the base. For example, Chinese Patent Publication No. CN105842051B discloses a "pole pole thrust test device". The upper pressure block is formed above the rotating table and can move up and down relative to the rotating table, pressing against the base of the pole. In this way, when the pole is fixed on the rotating table, the upper pressure block presses against the base of the pole, so that the base is fixedly embedded in the rotating table. The thrust rod applies a radial force to the pole to perform a thrust test on the pole. The structure is relatively simple, and the rotating table can drive the pole to rotate horizontally. It can perform thrust tests on multiple directions of the pole at one time, and the testing efficiency is high.

[0004] However, in actual use, different battery models have different terminal diameters, requiring the use of different sized bases to fix the terminals. This not only affects testing efficiency but also easily leads to mismatch between the terminals and the base, resulting in errors in the testing structure. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the existing technology where different battery models have different terminal diameters, requiring the use of different sized bases to fix the terminals. This not only affects testing efficiency but also easily leads to mismatch between the terminals and the base, resulting in errors in the testing structure. Therefore, this invention proposes a terminal radial thrust testing fixture.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A radial thrust test fixture for a pole column is designed, including a mounting part, a support block on the mounting part, a mounting groove on the support block that mates with the pole column, a slot on one side of the mounting groove, a locking member fixedly mounted on the pole column, the locking member being inserted into the slot, two clamping blocks on the support block, both clamping blocks abutting against the pole column to form a clamping structure, and the support block being connected to the clamping blocks through a connecting structure.

[0008] Furthermore, the connection structure includes a sliding groove, and each clamping block is provided with a slider that cooperates with the sliding groove.

[0009] Furthermore, each slider is provided with a limit block, and the slide groove is provided with a limit groove that cooperates with the limit block.

[0010] Furthermore, a double-ended screw is rotatably mounted on the support block, and the double-ended screw is threadedly connected to the two limiting blocks. One end of the double-ended screw passes through the support block and is fixedly connected to a knob.

[0011] Furthermore, a connecting cylinder is fixedly provided at the lower end of the mounting part, and the mounting part is connected to the testing device through the connecting cylinder. The testing device is provided with a punch that cooperates with the pole post.

[0012] Furthermore, the support block is fixedly connected to the support block by bolts, and the clamping block is fixedly connected to the limiting block and the slider by bolts.

[0013] The radial thrust testing fixture for pole columns proposed in this utility model has the following advantages:

[0014] In this utility model, the electrode is fixed by setting a slot and inserting a clip into the electrode post, and the electrode post is further fixed by setting a clamping block, so that the electrode post is only subjected to force in one direction during testing, thus avoiding errors in the test results caused by uneven force on the electrode post.

[0015] Secondly, in this utility model, by setting a clamping block to assist in fixing the pole post, and by setting a connecting structure to control the position of the clamping block, pole posts of different diameters can be clamped and fixed, thereby improving the applicability of the clamp.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A radial thrust test fixture for a pole post includes a mounting part 1, a support block 2 on the mounting part 1, a mounting groove 4 on the support block 2 that mates with a pole post 3, a slot 5 on one side of the mounting groove 4, a clip 6 fixedly mounted on the pole post 3, the clip 6 being inserted into the slot 5, and two clamping blocks 7 on the support block 2, both of which abut against the pole post 3 to form a clamping structure. The support block 2 is connected to the clamping blocks 7 through a connecting structure 8.

[0023] In this invention, the electrode 3 is fixed by inserting the slot 5 into the clip 6 of the electrode 3, and the electrode 3 is further fixed by setting the clamping block 7, so that the electrode 3 is subjected to force in only one direction during the test, thus avoiding errors in the test results caused by uneven force on the electrode 3.

[0024] Furthermore, in this embodiment, the connecting structure 8 includes a sliding groove 81, and each of the clamping blocks 7 is provided with a slider 82 that cooperates with the sliding groove 81. The sliding groove 81 is a dovetail groove or a T-shaped groove, and the slider 82 is a corresponding dovetail block or T-shaped block.

[0025] Furthermore, in this embodiment, each slider 82 is provided with a limiting block 83, and the slide groove 81 is provided with a limiting groove 84 that cooperates with the limiting block 83. By setting the limiting block and the limiting groove 84 to cooperate, the position of the clamping block 7 is restricted, preventing the clamping block 7 from separating from the support block 2.

[0026] It should be noted that, in this embodiment, a double-ended screw 85 is rotatably provided on the support block 2. The double-ended screw 85 is threadedly connected to two limiting blocks 83. One end of the double-ended screw 85 passes through the support block 2 and is fixedly connected to a knob. By rotating the knob, the double-ended screw 85 is driven to rotate, which drives the two limiting blocks 83 and the clamping block 7 to move towards each other or away from each other, thereby clamping or releasing the pole post 3. It can also clamp and fix pole posts 3 of different specifications.

[0027] Furthermore, in this embodiment, a connecting cylinder 9 is fixedly provided at the lower end of the mounting part 1. The mounting part 1 is connected to the testing device through the connecting cylinder 9. The testing device is provided with a punch 31 that cooperates with the pole post 3. The connecting cylinder 9 is provided with a fixing hole. During testing, the connecting cylinder 9 of the fixture can be connected to the testing device.

[0028] More specifically, in this embodiment, the support block 2 is fixedly connected to the support block 2 by bolts, and the clamping block 7 is fixedly connected to the limiting block 83 and the slider 82 by bolts. The clamping block 7 is replaced when it is severely worn, thus extending the service life of the clamp.

[0029] Working method: During operation, the electrode 3 is fixed by inserting the slot 5 into the clamp 6 of the electrode 3. By rotating the knob, the double-headed screw 85 is rotated, which drives the two limit blocks 83 and the clamping block 7 to move towards each other or away from each other, clamping or releasing the electrode 3. It can clamp and fix electrode 3 of different specifications.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
