Description

Technical Field

[0001] This invention relates to the field of casting inspection technology, specifically to a non-destructive testing device for internal defects in castings. Background Technology

[0002] Castings generally refer to finished products with predetermined shapes, sizes, and properties obtained by melting metal into a liquid that meets certain requirements, pouring it into a mold, cooling and solidifying it, and cleaning it. They are basic components in the machinery manufacturing industry. During the casting production process, internal defects such as porosity, sand holes, cracks, and slag inclusions are easily generated. If these defective castings flow directly into downstream production stages, they will bring serious safety hazards to subsequent processing and the use of finished products.

[0003] Traditional detection devices still have certain shortcomings in use:

[0004] 1. Traditional inspection methods rely on manual handheld inspection probes to scan castings one by one, which is not only inefficient but also fails to effectively identify internal and surface defects in castings. The stability and accuracy of the inspection results are greatly affected by human factors.

[0005] 2. The inability to quickly transfer the inspected castings to the conveyor platform increases the workload of workers in transporting the castings, slows down the pace of the overall inspection process, and results in poor continuity of the overall inspection process, thus slowing down the overall work efficiency when inspecting batches of castings. Summary of the Invention

[0006] The purpose of this invention is to provide a non-destructive testing device for internal defects in castings, in order to solve the problems mentioned in the background art. Traditional testing often relies on manual handheld probes to scan the castings one by one, which is not only inefficient, but also cannot effectively understand the internal and surface defects of the castings. The stability and accuracy of the test results are greatly affected by human factors. After testing, the castings cannot be quickly transferred to the conveyor platform, which increases the workload of workers in transporting castings, slows down the pace of the overall testing process, and results in poor continuity of the overall testing process, thus slowing down the overall work efficiency when testing castings in batches.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0011] As a preferred embodiment of the present invention, a stabilizing block is fixedly connected to the side of the working plate, and a groove is provided on the inner surface wall of the bearing box, with the stabilizing block extending into the groove and slidably connected to it.

[0012] As a preferred embodiment of the present invention, a belt conveyor body is provided on the side of the carrier box, and one end of the belt conveyor body extends into the carrier box and is located at the bottom of the working plate.

[0013] As a preferred embodiment of the present invention, a support base is fixedly connected to the bottom of the carrier box, a carrier base is fixedly connected to the bottom of the belt conveyor body, and a movable wheel is movably connected to the bottom of the carrier base.

[0014] As a preferred embodiment of the present invention, the groove is arc-shaped, and the top of the working plate is made of stainless steel.

[0017] In a preferred embodiment of the present invention, the support plate is located directly above the working plate, and the working plate is located at the top of the belt conveyor body.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, by using a junction box, industrial camera, X-ray inspection instrument, searchlight, data cable, and industrial display in combination, the industrial camera can capture and record images of the casting surface, and the X-ray inspection instrument can detect internal defects in the casting. All inspection data can be transmitted to the industrial display via the data cable for display. There is no need for manual scanning of each area with a handheld probe, which reduces the interference of human factors on the inspection results, improves the stability and accuracy of the inspection results, and effectively increases the inspection speed of a single casting, making it suitable for the inspection needs of batch castings.

Therefore, when the telescopic cylinder is adjusted, the working plate can easily tilt downwards, thereby quickly transferring the inspected castings to the belt conveyor, effectively improving work efficiency. At the same time, since the stabilizing block and the groove are slidably connected, the working plate has stability during the tilting process. Attached Figure Description
