Description

Technical Field

[0001] The utility model belongs to the technical field of part size gauges, in particular to an end size gauge suitable for a battery pole. Background Art

[0002] The poles of a battery usually refer to the two polarity terminals inside the battery, namely the positive pole and the negative pole. These poles are the key components of the battery, through which the input and output of current are realized. The positive and negative poles of the battery generate current through the chemical reaction of the electrolyte and the battery, which is then supplied to the external circuit or device. These poles are also the key interface between the battery and external devices. During the assembly process of the battery, the terminal needs to be welded to the pole, so the matching size of the pole and the terminal is particularly critical.

[0003] The produced pole is a cone, and its head size needs to be tested before use. However, the head heights of poles of different models are different, and the position of the detector needs to be adjusted before testing, which makes the test very inconvenient. Utility Model Content

[0006] An auxiliary component is arranged between the measuring platform and the collar, and the auxiliary component comprises a plug-in block and a spring. One end of the plug-in block is movably plugged into the collar, and two ends of the spring are respectively fixedly connected to the plug-in block and the collar.

[0007] As a preferred embodiment of the above technical solution, an adjustment component is provided at the bottom of the measuring platform, and the adjustment component includes a plurality of circumferentially arranged telescopic blocks, one end of the telescopic block is movably inserted in the measuring platform, and the telescopic block is provided with an elastic block.

[0008] As a preferred embodiment of the above technical solution, a rotating block is rotatably inserted into the other end of the telescopic block, and the rotating block is firstly adapted to fit the surface of the pole product through the telescopic block.

[0009] As a preferred embodiment of the above technical solution, a bolt is provided on one side of the collar, and one end of the bolt contacts the surface of the guide rod to fix the collar and the guide rod by static friction.

[0010] As a preferred embodiment of the above technical solution, the surface of the guide rod is provided with scales.

[0011] The beneficial effects of the utility model are:

[0012] 1. The position of the measuring platform is adjusted by moving the collar, so that pole products of different heights can be tested. At the same time, the measuring platform can be moved up a certain distance with the help of auxiliary components without affecting the placement of the pole products.

[0013] 2. Use multiple telescopic blocks to block the pole product so that it is automatically centered, so that the end of the pole product is in the detection position of the laser measuring instrument, which is convenient for the laser measuring instrument to detect the end of the pole product.

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings of the specification.

[0019] Example

[0020] Figure 1-Figure 3 The end dimension gauge for battery poles includes: a measuring platform 10 and a placing base 20, wherein a laser measuring instrument 30 is arranged on the top of the measuring platform 10, a collar 40 is arranged on one side of the measuring platform 10, a guide rod 50 is movably inserted inside the collar 40, a scale is arranged on the surface of the guide rod 50, and the bottom of the guide rod 50 is fixedly connected to the placing base 20;

[0021] An auxiliary component is provided between the measuring platform 10 and the collar 40 , and the auxiliary component includes a plug-in block 61 and a spring 62 . One end of the plug-in block 61 is movably plugged into the collar 40 , and both ends of the spring 62 are fixedly connected to the plug-in block 61 and the collar 40 , respectively.

[0022] The position of the measuring platform 10 is adjusted by moving the collar 40, so that pole products of different heights can be inspected. Meanwhile, the measuring platform 10 can be moved up a certain distance with the assistance of auxiliary components without affecting the placement of the pole products.

[0023] Figure 3 In the embodiment, an adjustment assembly 70 is provided at the bottom of the measuring platform 10. The adjustment assembly 70 includes a plurality of circumferentially arranged telescopic blocks 71. One end of the telescopic block 71 is movably plugged into the measuring platform 10, and an elastic block 72 is provided between the telescopic block 71 and the measuring platform 10.

[0024] The other end of the telescopic block 71 is rotatably plugged with a rotating block 73 , and the rotating block 73 first extends the telescopic block 71 and fits the surface of the pole product.

[0025] The pole product is blocked by multiple telescopic blocks 71 to be automatically centered, so that the end of the pole product is in the detection position of the laser measuring instrument 30, which facilitates the laser measuring instrument 30 to detect the end of the pole product. In addition, the multiple telescopic blocks 71 can limit the pole product and will not be displaced by external forces to affect the detection results.

[0026] Figure 1-Figure 3 In the embodiment, a bolt 80 is provided on one side of the collar 40, and one end of the bolt 80 contacts the surface of the guide rod 50 to fix the collar 40 and the guide rod 50 by static friction.

[0027] The collar 40 and the guide rod 50 are fixed by static friction between the bolt 80 and the surface of the guide rod 50 , so that the collar 40 and the measuring platform 10 can be adjusted quickly and conveniently, making the use more convenient.

[0028] Working principle: When testing pole products of different heights, the bolt 80 is rotated to disconnect the static friction fixation between the collar 40 and the guide rod 50, and then the collar 40 can be pushed to drive the measuring platform 10 and the laser measuring instrument 30 to move. After precise adjustment according to the scale on the surface of the guide rod 50, the bolt 80 is rotated again to fix the collar 40 on the surface of the guide rod 50, and then the measuring platform 10 is pushed upward to drive the plug-in block 61 to move, and the spring 62 is compressed and deformed accordingly. The distance of the measuring platform 10 moving up one end does not affect the placement of the pole product. After the pole product is placed, under the action of gravity and the reset thrust of the spring 62, the measuring platform 10 moves down to make the laser measuring instrument 30 return to the detection position. In this process, the rotating block 73 contacts the surface of the pole product, and multiple rotating blocks 73 are squeezed to shrink the telescopic block 71 into the measuring platform 10 and squeeze and deform the elastic block 72. At the same time, the pole product is pushed in the opposite direction by the multiple rotating blocks 73 to be centered, which facilitates the laser measuring instrument 30 to detect the end of the pole product.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
