Description

Technical Field

[0001] This utility model relates to the field of alloy casting inspection technology, and in particular to an alloy casting flaw detection device. Background Technology

[0002] In the production and manufacturing process of alloy castings, flaw detection is a key step in ensuring the quality of castings. Through flaw detection, defects such as cracks, porosity, and looseness inside the castings can be detected in a timely manner, avoiding serious consequences caused by casting quality problems.

[0003] Currently, most commercially available alloy casting flaw detection devices require operators to hold the probe firmly against the casting surface for inspection. However, this method has several drawbacks. First, holding the probe for extended periods can lead to operator fatigue, affecting inspection efficiency and accuracy. Removing the probe from the casting when pausing inspection is also inconvenient when resuming. Second, when inspecting irregularly shaped or uneven alloy castings, maintaining a stable contact between the probe and the casting surface is difficult, thus affecting the reliability of the inspection results.

[0004] Therefore, this application provides an alloy casting flaw detection device to meet the requirements. Utility Model Content

[0005] The purpose of this application is to provide an alloy casting flaw detection device to solve the problems in the prior art where the probe is difficult to fix stably and the operation is inconvenient to continue detection after pausing.

[0006] To achieve the above objectives, this application provides the following technical solution: an alloy casting flaw detection device, comprising a flaw detector body, wherein the flaw detector body is connected to a probe via a wire, and the detection device further comprises a sleeve and a housing; The sleeve is fitted over the outside of the probe, and symmetrical mounting grooves are provided on the side wall of the sleeve, each of which is rotatably connected to a gear.

[0007] The sleeve is fitted over the outside of the tube, and a magnetic block is provided at the bottom of the sleeve for adsorbing the casting.

[0008] The probe has symmetrical inner vertical grooves on its outer wall, and the housing has symmetrical outer vertical grooves on its inner wall. Both the inner and outer vertical grooves are adapted to the gear. Both the inner and outer vertical grooves can slide vertically along the gear. Both the inner and outer vertical grooves have racks inside that mesh with the gear. Through the cooperation of the gear and the rack, when the probe is operated for testing, the housing can be moved in the opposite direction, causing the magnetic block to detach from the casting. The top of the sleeve is provided with a top cover, and the outer wall of the probe is provided with a ring seat and a protrusion. A return spring is press-fitted between the bottom of the ring seat and the top cover. The protrusion limits the top cover from below. The setting of the return spring enables the probe to automatically reset when no external force is applied. The gear drives the sleeve to move in the opposite direction, so that the magnetic block contacts and attracts the casting, thereby keeping the probe in its original position, improving the convenience and stability of the detection device.

[0009] Preferably, the probe has symmetrically arranged inner guide grooves on its outer wall, the housing has an outer guide groove on its inner wall, and the sleeve has symmetrically arranged inner guide bars on its inner wall, the inner guide bars being adapted to the inner guide grooves. The sleeve has symmetrically arranged outer guide bars on its outer wall, the outer guide bars being adapted to the outer guide grooves. The cooperation between the inner guide bars and the inner guide grooves, and between the outer guide bars and the outer guide grooves, further enhances the stability and guidance of the relative movement between the probe, the sleeve, and the housing, preventing deviation or shaking during movement, thereby ensuring the stable transmission of the gear and the rack. Preferably, the bottom of the sleeve is provided with a bottom ring, and the bottom surface of the bottom ring is provided with a universal ball. The universal ball is provided in multiple sets and is evenly distributed. The universal ball allows the sleeve to move flexibly on the surface of the casting, reducing the friction when the probe moves and facilitating the detection of different parts of the casting. Preferably, the bottom of the casing is provided with a ring, the inner wall of the ring is slidably connected to the outer wall of the bottom ring, and the bottom of the ring is provided with a base plate. The base plate is annular and corresponds to the position of the bottom ring. The bottom surface of the base plate is provided with a ball groove and a magnetic block. There are multiple sets of ball grooves and magnetic blocks, which are evenly staggered. The ball groove is used to allow the universal ball to move. This structural design not only limits the relative travel between the sleeve and the casing through the cooperation of the base plate and the bottom ring, but also leaves room for the universal ball to move. The structure is compact and stable. Preferably, the upper outer wall of the probe is provided with a grip sleeve, which makes it easier for the operator to hold the probe and improves the comfort and convenience of operation.

[0010] In summary, the technical effects and advantages of this utility model are as follows: 1. Improved operational flexibility: The gear and rack, guide bar and guide groove design allows the probe and sleeve to move in opposite directions inside and outside the sleeve, changing the distance between the magnetic block at the bottom of the sleeve and the alloy casting. This adjusts the attraction state between the magnetic block and the alloy casting, allowing operators to leave the probe in its original position when pausing the inspection. This helps ensure the accuracy of the inspection and allows for continuous and thorough flaw detection of the casting. It also avoids affecting the inspection results due to changes in the probe's position, thus improving the accuracy and reliability of the inspection. 2. Convenient operation: The magnetic block can be released from the casting by pressing the probe, making it easy for operators to operate the probe flexibly. At the same time, the reset spring allows the probe to automatically reset and bring the magnetic block close to the casting for automatic attraction, reducing operation steps and improving detection efficiency. In addition, the grip further enhances the comfort and convenience of operation. 3. Good adaptability: The universal ball reduces the friction of the probe when moving on the surface of the casting, allowing the testing device to move flexibly on the surface of alloy castings with irregular shapes and uneven surfaces, thus expanding the application range of the testing device and meeting the flaw detection needs of different types of alloy castings.

The probe 2 has symmetrical inner vertical grooves 22 on its outer wall and the housing 4 has symmetrical outer vertical grooves 42 on its inner wall. Both the inner vertical grooves 22 and the outer vertical grooves 42 are adapted to the gear 32. The inner vertical grooves 22 and the outer vertical grooves 42 are slidably connected on both sides of the gear 32. Both the inner vertical grooves 22 and the outer vertical grooves 42 have racks that mesh with the gear 32 inside. The top of the sleeve 3 is provided with a top cover, and the outer wall of the probe 2 is provided with a ring seat 21 and a protrusion. A return spring 5 is press-fitted between the bottom of the ring seat 21 and the top cover, and the protrusion limits the top cover from below.

[0016] As one implementation method in this embodiment, to enhance the stability when the probe 2, sleeve 3, and housing 4 move relative to each other, such as... Figures 4 to 6 As shown, the probe 2 has an inner guide groove 23 symmetrically arranged on its outer wall, the housing 4 has an outer guide groove 44 symmetrically arranged on its inner wall, the sleeve 3 has an inner guide strip 33 symmetrically arranged on its inner wall, the inner guide strip 33 is adapted to the inner guide groove 23, and the sleeve 3 has an outer guide strip 34 symmetrically arranged on its outer wall, the outer guide strip 34 is adapted to the outer guide groove 44.

[0017] As one implementation method in this embodiment, to reduce the frictional force when probe 2 moves on the casting, such as... Figure 3 , Figure 5 As shown, the bottom of the sleeve 3 is provided with a bottom ring 30, and the bottom surface of the bottom ring 30 is provided with four sets of evenly distributed universal balls 31.

[0018] As one implementation method in this embodiment, in order to limit the relative travel of the sleeve 3 and the housing 4, such as... Figure 2 , Figure 3 as well as Figure 5 , Figure 6As shown, the bottom of the housing 4 is provided with a ring 40, the inner wall of the ring 40 is slidably connected to the outer wall of the bottom ring 30, the bottom of the ring 40 is provided with a base plate 41, the base plate 41 is ring-shaped and corresponds to the position of the bottom ring 30, the bottom surface of the base plate 41 is provided with a ball groove and a magnetic block 43, there are four sets of ball grooves and magnetic blocks 43, which are evenly staggered. The ball groove is used for the movement of the universal ball 31.

[0019] As one implementation method in this embodiment, to facilitate holding the probe 2 for flaw detection, such as... Figures 2 to 4 As shown, the upper outer wall of the probe 2 is provided with a grip sleeve 20.

[0020] The working principle of this device is as follows: When performing flaw detection, the magnetic block 43 at the bottom of the casing 4 is first adsorbed onto the surface of the part to be inspected on the alloy casting. The magnetic force of the magnetic block 43 makes the detection device stably fixed on the casting. Then, the operator takes over the operation, holds the grip sleeve 20 on the upper part of the probe 2, and presses the probe 2 towards the casting. The probe 2 moves inside the casing 3. Because the inner vertical groove 22 on the outer wall of probe 2 meshes with the gear 32 inside the sleeve 3 and the rack between the gear 32 and the outer vertical groove 42 on the inner wall of the housing 4, when probe 2 is pressed and moved, gear 32 will rotate with the movement of probe 2, causing housing 4 to move in the opposite direction, so that ring 40 and bottom ring 30 move relative to each other. In this process, firstly, universal ball 31 contacts the surface of the casting, and then probe 2 also approaches the surface of the casting. At the same time, during the process, the outer guide bar 34 on the outer wall of sleeve 3 and the outer guide groove 44 on the inner wall of housing 4, and the inner guide bar 33 on the inner wall of sleeve 3 and the inner guide groove 23 on the outer wall of probe 2 cooperate with each other, further ensuring the stability of the movement of probe 2 and ensuring the reliability of the linkage between probe 2 and housing 4 through gear 32. Finally, the bottom plate 41 at the bottom of housing 4 fits with the bottom ring 30 at the bottom of sleeve 3, limiting the stroke of housing 4. At this time, probe 2 is closest to the casting and can be inspected by flaw detector body 1.

[0021] When it is necessary to pause the test, the operator slowly releases the pressure on the probe 2. During this process, due to the automatic push of the ring seat 21 by the reset spring 5, the universal ball 31 at the bottom of the sleeve 3 remains in contact with the casting until the magnetic block 43 contacts and attracts the casting, so that the probe 2 is stabilized at the original test position, so that the operator can operate the flaw detector body 1 or take a break.
