Description

Technical Field

[0001] The utility model belongs to the field of lead-acid battery assembly, and in particular relates to a device for measuring the height and size of a welding hole of a battery slot. Background Art

[0002] The lead-acid battery assembly process first punches holes in the battery tank, and after the pole group is placed in the tank, the contact part of the welding parts is melted to fill the welding holes and solidify to achieve the connection between different pole groups. Different pole plates and battery tanks have different designs for the punching height and size. Punching too high or too low may cause the welding holes to be filled unsatisfactorily, causing gas / liquid crossover between the two cells, resulting in a decrease in the characteristic value, and even forming false welding.

[0003] At present, the welding hole is usually measured on site by using a conventional vernier caliper. The welding hole is placed inside the partition wall. When measuring the height, it is difficult to ensure that the depth measuring rod is parallel to the battery slot partition wall, and accurate measurement is impossible. When measuring the size of the welding hole, it is difficult for a conventional vernier caliper to penetrate deep inside to measure the hole size.

[0004] The currently disclosed measuring tool for the position of the butt welding hole includes more than one positioning pin, a height gauge, and a measuring claw. Each positioning pin includes a small step portion matching the butt welding hole and a large step portion connected to one side of the small step portion. The small step portion of each positioning pin corresponds to butt welding holes of different shapes and sizes. The measuring claw is a Z-shaped bending structure composed of a horizontal plate 1, a vertical plate connected to one end of the horizontal plate 1, and a horizontal plate 2 connected to the lower end of the vertical plate. The one end of the horizontal plate 1 is slidably connected to the lower inner frame of the measuring claw clamping frame of the height gauge. The upper surface of the horizontal plate 1 contacts the lower surface of the bracket of the height gauge and is fixed in the measuring claw clamping frame by a locking screw. The lower surface of the horizontal plate 2 is provided with more than one upper bayonet matching the structural size of the upper half of the butt welding hole. Each upper bayonet corresponds to butt welding holes of different shapes and sizes. A measuring plane is provided at the top of the lower surface of the horizontal plate 2. The structure is complex, and only the height of the butt welding hole can be measured. Whether the height of the butt welding hole meets the requirements is judged, and the measurement of the size of the butt welding hole cannot be completed. Summary of the invention

[0005] The purpose of the utility model is to solve the deficiencies of the above-mentioned prior art, thereby providing a battery slot butt welding hole height and size measuring device, which is convenient for measuring the butt welding hole height and size, and is convenient for operators to understand the drilling situation and adjust the equipment to the required value before production to avoid production abnormalities.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a device for measuring the height and size of a battery tank welding hole, comprising:

[0007] A height measuring device, the height measuring device comprising a main measuring ruler;

[0008] A stopper for positioning the butt welding hole is installed at the right end of the measuring main scale, and the right end face of the stopper is flush with the right end face of the measuring main scale. A vertical slide groove is provided on the measuring main scale, and the measuring vernier scale is slidably connected in the slide groove of the measuring main scale;

[0009] and a dimension measuring device, the dimension measuring device comprising a left positioning plate and a right positioning plate, the left positioning plate being vertically connected to the left end of the height measuring main ruler, and the right positioning plate being connected to the left end of the measuring vernier ruler;

[0010] Two parallel size measuring claws protrude from one side of the left positioning plate and the right positioning plate.

[0011] The measuring main scale is provided with scale marks, and the measuring vernier scale is provided with a zero scale mark;

[0012] When the two dimension measuring claws protruding from one side of the left positioning plate and the right positioning plate are in contact, the zero scale line on the measuring vernier scale is flush with the zero scale line on the measuring main scale.

[0013] The blocking rod is cylindrical and matches the butt welding.

[0014] A static grid of a capacitive grid sensor is embedded in the bottom of the slideway of the measuring main scale, and a moving grid cooperating with the static grid is provided on the measuring vernier scale;

[0015] There is also a digital readout on the measuring vernier scale;

[0016] The digital display readout is connected to the capacitive grating sensor and is used for displaying the displacement data measured by the capacitive grating sensor.

[0017] The stopper rod can be stuck in the butt-welding hole when in use, so that the bottom of the caliper and the lower edge of the hole are at the same height, thereby ensuring the accuracy of height measurement.

[0018] The left positioning plate and the main measuring scale, as well as the right positioning plate and the height measuring vernier scale are all designed vertically, so that the dimension measuring claws can penetrate deep into the battery slot.

[0019] When the left positioning plate is in full contact with the protruding dimension measuring claws at one end of the right measuring plate, the caliper reading is 0.

[0020] The height and size measuring device of the utility model has a simple structure and is easy to operate, and can measure the height and size of the butt welding hole without much operation. BRIEF DESCRIPTION OF THE DRAWINGS

The moving distance is measured by the relative displacement of the static grid and the dynamic grid of the capacitive grid sensor. The capacitive grid sensor is a common product on the market, such as the TM-003 model. A digital display reader 3 is fixed on the measuring vernier scale 2, and the digital display reader 3 is connected to the capacitive grid sensor to display the displacement data measured by the capacitive grid sensor. A stopper 9 for locating the butt-welding hole is installed at the right end of the measuring main scale 1. The stopper 9 is cylindrical and matches the butt-welding hole.

There is a zeroing key 8 on the digital display reader 3, and then start height measurement. First, measure the main scale 1 upright, then insert the blocking rod 9 into the butt-welding hole, and then slide the measuring vernier scale 2 downward until the measuring vernier scale 2 touches the bottom of the battery slot. The data displayed on the digital display reader 3 is the height. When measuring the size, let the two dimension measuring claws protruding from one side of the left positioning plate 4 and the right positioning plate 5 touch each other, then return the digital display reader 3 to zero, and then pick up the measuring main scale 1 horizontally, let the two dimension measuring claws extend into the inside of the butt-welding hole, and then slide the measuring vernier scale 2. The measuring vernier scale 2 moves with the right positioning plate 5 until the two dimension measuring claws can no longer be opened. The data displayed on the digital display reader 3 is the butt-welding hole size. Example 2
