Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fixture, especially to a pole drawing force test fixture. BACKGROUND

[0002] The battery pole is an important component of the battery, which is a special structure of the battery's current collecting pole and strong corrosion resistance, and is generally composed of a pole body, a pole bottom and a pole head. Its shape, size and model need to be designed and manufactured according to different battery types, current requirements and environmental adaptability. The material selection principle of the battery pole requires the material to have high electrical conductivity, good corrosion resistance, dimensional stability and processing performance. Commonly used materials include copper, aluminum, zinc alloy and other metal materials. Pure copper has the best performance. The processing technology of the battery pole generally adopts cold extrusion and hot extrusion. Through the pressing and stretching of the die, the metal material is pressed into a cylindrical shape with precise holes and uniform density for easy assembly and use later.

[0003] The existing pole needs to be tested for drawing force after production, so as to determine the safety of the battery used in the environment with frequent vibration. For example, the battery pole test structure disclosed in Chinese patent No. CN218567072U fixes two drawing blocks at both ends of the bottom plate through the first bending part, then fixes the bottom plate and the pole with the pressing block through the locking nut, and then bends the two drawing blocks to approach each other. When the drawing block is subjected to tension, the tension direction coincides with the axis, so that the tensile strength of the pole can be accurately determined.

[0004] However, in actual use, the two bending parts connected with the bottom plate are prone to deformation of different amplitudes when drawing the pole, resulting in uneven stress of the pole and breaking, which affects the accuracy of the test results. UTILITY MODEL CONTENTS

[0005] The utility model aims at solving the problems in the prior art, such as the drawing structure being prone to deformation due to uneven stress, the pole being prone to breaking due to uneven stress, and the accuracy of the test results being affected, and proposes a pole drawing force test fixture.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A pole drawing force test fixture is designed, which comprises a mounting seat and a pole. The pole is arranged on the mounting seat. The mounting seat is provided with a fixing assembly matched with the pole. The mounting seat is provided with a drawing assembly. The drawing assembly is sleeved outside the pole. The drawing assembly is provided with a drawing hole.

[0008] The fixing component includes a fixing plate with a mounting groove, the pole being disposed in the mounting groove, a pressure plate on the fixing plate, and a through hole on the pressure plate that mates with the pole. The pole passes through the through hole and is connected to the pulling component.

[0009] Furthermore, a limiting part that cooperates with the pressure plate is fixedly provided on the pole post, and the limiting part is disposed between the pressure plate and the mounting groove.

[0010] Furthermore, the pulling assembly includes a clamping structure sleeved on the pole post, the clamping structure including two opposing clamps, and the clamping structure having an insertion hole that mates with the pole post.

[0011] Furthermore, each of the clamps is provided with a clamping groove, and each of the poles is fixedly provided with a pull-out part that cooperates with the clamping groove.

[0012] Furthermore, a sleeve is fitted around the outside of the clamping structure, and the pull-out hole penetrates the sleeve and the clamping structure.

[0013] Furthermore, the sleeve is inserted into the through hole on the pressure plate, and the lower end of the sleeve contacts the limiting part.

[0014] The electrode pull-out force testing fixture proposed in this utility model has the following advantages:

[0015] In this utility model, the electrode post is fixed by setting a fixing component to prevent the electrode post from separating from the fixing plate during pull-out. The electrode post is clamped and fixed by setting a pull-out component. Pulling the pull-out component upwards can perform a pull-out test on the electrode post, which is convenient and quick.

[0016] Secondly, in this utility model, the clamping structure of the pull-out assembly consists of two opposing clamps. When the pole is pulled out, the clamping groove on the clamps engages with the pull-out part of the pole. The pull-out test can be performed by moving the clamps upward. At the same time, a sleeve is provided on the outside of the clamping assembly to fix the clamping assembly, so that the two clamps are subjected to uniform force, which will not cause the pole to break due to uneven force, thus improving the test accuracy.
