Description

Technical Field

[0001] This utility model relates to the field of connecting rod magnetic particle flaw detection tooling technology, specifically a connecting rod magnetic particle flaw detection tooling. Background Technology

[0002] In fields such as automotive engines and construction machinery, connecting rods are core components for power transmission. Surface and near-surface defects (such as cracks and inclusions) directly affect equipment operational safety, thus requiring magnetic particle testing for quality inspection. During magnetic particle testing, the stability and ease of operation of the tooling are crucial to the testing accuracy.

[0003] When using existing magnetic particle inspection fixtures for connecting rods, (1) The magnetic powder spraying position is fixed, which makes it difficult to adjust flexibly according to different parts of the connecting rod, and uneven spraying is likely to cause defects to be missed. (2) The magnetic powder is wasted in large quantities. Excess magnetic powder is not collected, which pollutes the environment and increases costs. In addition, the stability of the connecting rod is insufficient, which affects the consistency of the test.

[0004] To address the aforementioned problems, this utility model provides a connecting rod magnetic particle flaw detection tool. Utility Model Content

[0005] The purpose of this invention is to provide a magnetic particle inspection fixture for connecting rods. This invention has the advantages of adjustable magnetic particle spraying position, high magnetic particle utilization rate and stable connecting rod placement, thereby solving the problems of fixed magnetic particle spraying position, magnetic particle waste and unstable connecting rod placement in existing fixtures.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a connecting rod magnetic particle flaw detection fixture, including a fixed base and an adjustable flaw detection component, wherein the adjustable flaw detection component is fixedly connected to the back of the top of the fixed base, and the adjustable flaw detection component includes a support plate fixedly connected to the back of the top of the fixed base; A fixing plate is fixedly connected to the top of the support plate, a connecting plate is fixedly connected to one side of the bottom of the fixing plate, a protective box is fixedly connected to the center of the front of the connecting plate, a motor box is fixedly connected to one side of the protective box, a servo motor is fixedly connected inside the motor box, and a transmission rod is fixedly connected to the output end of the servo motor.

[0007] Furthermore, one end of the transmission rod is fixedly connected to a threaded rod, and one end of the threaded rod is rotatably connected to the inner wall of the protective box. A sliding plate is threadedly connected to the surface of the threaded rod, and the sliding plate is slidably connected to the inner wall of the protective box. This achieves the function of the servo motor driving the threaded rod to rotate through the transmission rod, causing the sliding plate to slide horizontally along the inner wall of the protective box, thereby realizing the position adjustment of the magnetic powder placement box and adapting to the magnetic powder spraying requirements of different parts of the connecting rod. Furthermore, a magnetic powder placement box is fixedly connected to the surface of the sliding plate, and a transmission head is connected through the bottom of the magnetic powder placement box. This achieves the function of storing magnetic powder in the magnetic powder placement box and directionally conveying the magnetic powder to the surface of the connecting rod by the transmission head, ensuring that the magnetic powder evenly covers the detection area.

Furthermore, a groove is provided in the middle of the top of the fixed base, and a collection support assembly is fixedly connected to the inner wall of the groove. The collection support assembly includes a collection box fixedly connected to the middle of the top of the fixed base, and support frames are fixedly connected to both sides of the bottom wall of the collection box. This achieves the effect of the collection box collecting excess magnetic powder, realizing resource recycling and environmental cleaning; the support frames stably support the connecting rod, preventing the connecting rod from shaking during detection and ensuring the stability of the detection. Furthermore, fixing strips are fixedly connected to both sides of the top of the collection box, and handles are fixedly connected to the surface of the fixing strips.

[0014] Specifically, when operating the device, the operator first places the connecting rod on the support frame 302 inside the collection box 301 to ensure the stability of the connecting rod; then, magnetic powder is added to the magnetic powder placement box 210, the servo motor 206 is started, and the position of the magnetic powder placement box 210 is adjusted to align it with the part of the connecting rod to be tested; then, the hydraulic rod 215 is controlled to drive the anti-leakage block 216 to rise, the transmission head 211 is opened, and the magnetic powder is sprayed onto the surface of the connecting rod through the transmission head 211 and the circular filter plate 219; after the test is completed, the transmission head 211 is closed, the collection box 301 is removed by holding the rod 304, excess magnetic powder is recovered, and the connecting rod is cleaned. Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided: One end of the transmission rod 207 is fixedly connected to a threaded rod 208, and one end of the threaded rod 208 is rotatably connected to the inner wall of the protective box 204. A sliding plate 209 is threadedly connected to the surface of the threaded rod 208, and the sliding plate 209 is slidably connected to the inner wall of the protective box 204. The purpose of this design is that the servo motor 206 drives the threaded rod 208 to rotate through the transmission rod 207, so that the sliding plate 209 slides horizontally along the inner wall of the protective box 204, thereby driving the magnetic powder placement box 210 to move, realizing precise adjustment of the magnetic powder spraying position, and adapting to the detection needs of different parts of the connecting rod (such as the large end, small end, and rod body). Furthermore, such as Figure 2 As shown, the following preferred technical solutions are provided: A magnetic powder placement box 210 is fixedly connected to the surface of the sliding plate 209. A transmission head 211 is connected through the bottom of the magnetic powder placement box 210.

The handles 304 make it convenient for operators to move or remove the collection box 301, and facilitate cleaning of residual magnetic powder inside and maintenance of the equipment. Working principle: This connecting rod magnetic particle inspection fixture achieves precise spraying of magnetic powder by adjusting the inspection component 2. The servo motor 206 drives the threaded rod 208 to move the sliding plate 209, adjusting the position of the magnetic powder placement box 210. The hydraulic rod 215 controls the anti-leakage block 216 to open and close the transmission head 211. After being filtered by the circular filter plate 219, the magnetic powder is evenly sprayed onto the surface of the connecting rod and collected in the support component 3. The support frame 302 fixes the connecting rod, and the collection box 301 recovers excess magnetic powder. The handle 304 facilitates the picking and putting in of the collection box 301.
