AI Technical Summary
Existing welded steel plate strength testing devices are not precise in controlling the height of the load, resulting in inaccurate testing and laborious operation.
A testing device including a column and a pull-out plate was designed. A heavy ball is placed on the pull-out plate, and the ball falls and hits the welding part by pulling the plate backward. The adjustable perforation of the pull-out plate and the mass of the heavy ball ensure that the height of the heavy object hitting the welding position is accurate, and the ball is prevented from rolling by a clamp and spring structure.
It achieves accurate height of heavy objects falling on the welding position, resulting in more accurate test results and making the welding steel plate strength test easier to operate.

Technical Field
[0001] This utility model relates to the field of testing technology, specifically to a testing device for the strength of welded steel plates. Background Technology
[0002] The welded steel plates include a left steel plate on the left and a right steel plate on the right, with the welded area between the left and right steel plates.
[0003] The welded steel plate bearing capacity testing device is used to test the bearing capacity of welded steel plates. The device includes a base with clamps for holding the steel plate. The clamps include a left clamp installed on the left side of the base and a right clamp installed on the right side of the base. During the test, the left and right sides of the welded steel plate are clamped by the left and right clamps, respectively. The welded part is located between the left and right clamps. The tester holds a heavy ball at a certain height and drops it onto the welded part. The deformation of the welded part is then observed or tested to determine the bearing capacity of the welded steel plate.
[0004] In the existing technology, the welded steel plate strength testing device requires the tester to hold a heavy object and drop it, which has the disadvantages of inaccurate control of the height of the heavy object and inaccurate testing. It also has the disadvantage of requiring a lot of effort to hold the heavy ball. These issues need to be improved. Summary of the Invention
[0005] The purpose of this invention is to address the above-mentioned shortcomings by providing a welding steel plate strength testing device that accurately measures the height at which a heavy object is dropped on the welding position, provides more accurate test results, and is easier to operate.
[0006] The technical solution of this utility model is implemented as follows: A welding steel plate strength testing device includes a base, on which a clamp for holding the steel plate is provided. The clamp includes a left clamp installed on the left side of the base and a right clamp installed on the right side of the base. The left and right clamps are respectively the left and right parts for holding the welding steel plate, and the welding part is located between the left and right sides of the welding steel plate. The device is characterized by: a column installed on the base, the column having a through hole for a pull-out plate, and a pull-out plate installed in the through hole. It also includes a weighted ball placed on the pull-out plate. In use, the front of the pull-out plate extends beyond the column, and the weighted ball is placed on the extended portion. The weighted ball is located above the welding part. When the pull-out plate is pulled backward, the weighted ball disengages from the support of the extended portion of the pull-out plate and falls onto the welding part.
[0007] Furthermore, the pull-out plate has a low groove in the middle, which is used to hold the heavy ball in place and prevent it from rolling left and right.
[0008] Furthermore, the fixture includes a rear fixture mounting plate, the mounting plate has a clamping piece, the clamping piece has a clamping end, the clamping piece includes an upper clamping piece and a lower clamping piece, the mounting plate has a vertical sliding groove, the upper clamping piece has a slider behind it, the slider is installed in the sliding groove, and there is a spring pressing against the slider in the sliding groove.
[0009] The beneficial effects of this utility model are: such a welded steel plate strength testing device has the advantages of accurate height of the weight dropped on the welding position, more accurate test results, and less effort to use. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.
[0015] like Figure 1 , 2 As shown in Figure 3, a welded steel plate strength testing device includes a base 1, on which a clamp 2 for holding the steel plate is provided. The clamp includes a left clamp 21 installed on the left side of the base and a right clamp 22 installed on the right side of the base. The left and right clamps are respectively the components for holding the left and right sides of the welded steel plate 3, and the welding part 31 is located between the left and right sides of the welded steel plate. The device is characterized by: a column 4 installed on the base, the column having a pull-out plate through hole 41, and a pull-out plate 5 installed in the pull-out plate through hole. It also includes a weighted ball 6 placed on the pull-out plate. In use, the front of the pull-out plate extends beyond the column, and the weighted ball is placed on the extended part. The weighted ball is above the welding part. When the pull-out plate is pulled backward, the weighted ball disengages from the support of the extended part of the pull-out plate and falls to hit the welding part.
[0016] In use, the steel plate to be welded is clamped in a fixture, a column extends out from the front of the pull plate, and a weight ball is placed on the extended part of the column. The welded part is below the weight ball. Then, the pull plate is pulled in the opposite direction of the weight ball, causing the weight ball to fall and hit the welded part. After a certain number of times, the deformation of the welded part can be detected, and the strength of the welded steel plate can be known.
[0017] In one technical solution, the pull-out plate has multiple perforations, which are distributed at different heights on the column.
[0018] This invention also features a design that allows for the selection of pull-out plates with perforations at different heights, enabling the dropping of heavy balls at varying heights, thus making it more convenient to use.
[0019] In one technical solution, there are multiple heavy balls, and the multiple heavy balls have different masses.
[0020] This invention also allows for the selection of heavy balls of different masses for testing, making selection more convenient.
[0021] Furthermore, the pull-out plate has a low groove 51 in the middle, which is a groove that holds the heavy ball in place and prevents the heavy ball from rolling left and right.
[0022] This design prevents the heavy ball from rolling left and right.
[0023] Furthermore, the fixture includes a rear fixture mounting plate 23, the mounting plate having a clamping piece 24, the clamping piece having a clamping end, the clamping piece including an upper clamping piece 241 and a lower clamping piece 242, the mounting plate having a vertical sliding groove 231, the upper clamping piece having a slider 2411 behind it, the slider being installed in the sliding groove, and a spring 25 pressing against the slider in the sliding groove.
[0024] In fact, the clamp can be any clamp from the prior art, as long as it can hold the steel plate.
[0025] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
