Description

Technical Field

[0001] The utility model belongs to the field of production line equipment, and in particular relates to a detection device for automobile aluminum die-casting parts. Background Art

[0002] With the continuous development of new energy vehicles, parts in certain positions of the car are gradually replaced by aluminum castings instead of the original steel castings. This not only reduces costs, but also reduces the weight of the vehicle without affecting the structural strength of the vehicle.

[0003] For a certain workshop, due to the different models of vehicles of the same brand, the sizes of aluminum castings at a certain position are not exactly the same. For example, the suspension connecting rods of model A and model B vehicles have different sizes.

[0004] When performing radiographic flaw detection on the two aluminum castings of different sizes, the following problems are encountered:

[0005] The principle of radiographic inspection is that X-rays pass through a part. If there are cracks on the part's surface, the cracks create a light-sensitive area on the photosensitive plate. The photosensitive plate and X-rays must be on opposite sides of the part. If the X-rays are above the part, the photosensitive plate must be below it. The X-rays pass downward through the part and are detected by the photosensitive plate below the part.

[0006] To ensure smooth exposure of the photosensitive plate, traditional conveyor belts are not sufficient because they are continuous belts with no intervening spaces. Firstly, there is no space to place the photosensitive plate. Secondly, even if the plate is placed, the X-rays, after passing through the part, need to pass through the belt again, which weakens the X-rays and reduces the sensitivity.

[0007] To minimize these drawbacks, testing equipment has emerged that uses two conveyor belts simultaneously carrying parts. The two belts do not touch each other, leaving a gap between them where a photosensitive plate can be placed. This allows X-rays to pass through the part and then through the gap to the photosensitive plate, eliminating the need to pass through the conveyor belts. While the edges of the part that touch the conveyor belts still need to pass through the conveyor belts, resulting in poor photosensitive results, simply by adjusting the part's placement angle—for example, rotating it 90 degrees before performing a second inspection—then the edge of the part can be inspected, achieving full inspection.

[0008] However, because the middle area of the conveyor belts is empty, it cannot fully support aluminum castings of different sizes. For example, aluminum castings smaller than the size of the gap cannot be mounted on both conveyor belts at the same time. Therefore, a detection device that can adjust the gap between the two conveyor belts is needed to meet the requirements of supporting aluminum castings of different sizes. Utility Model Content

[0009] The utility model provides a detection device for automobile aluminum die-casting parts, which can adjust the gap between two conveyor belts.

DETAILED DESCRIPTION

[0048] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0049] See Figure 1 and Figure 2 A testing device for automotive aluminum die-cast parts includes several conveyor belt units and several testing units. Parts are sequentially conveyed along the surfaces of the multiple conveyor belt units and inspected by the multiple testing units. The system then determines whether the parts are defective based on the test results from the multiple testing units.

[0050] See Figure 2 , the conveyor belt unit includes:

[0051] The base frame 1 is placed on the ground. In this embodiment, the base frame 1 is in the shape of a rectangular frame in a top view, and the direction of one side of the base frame 1 is the X direction, and the direction of the other adjacent side is the Y direction.

[0052] Two sets of drive components are arranged on the base frame 1, and the two sets of drive components are arranged side by side along the X direction. The drive components include:

[0053] The two vertical blocks 2 are fixedly connected to the upper surface of the base frame 1, and the two vertical blocks 2 are arranged side by side along the Y direction. Figure 2 This is just a schematic diagram, so the shapes of the two vertical blocks 2 are not consistent. In actual situations, the shapes of the two vertical blocks 2 are consistent.

[0054] The two ends of the cross bar 3 are respectively fixed on the two vertical blocks 2, and the axis of the cross bar 3 is along the Y direction.

[0055] The threaded rod 4 has two ends rotatably connected to the two vertical blocks 2, and the axis of the threaded rod 4 is along the Y direction.

[0056] The movable support block 5 is simultaneously sleeved on the cross bar 3 and the threaded rod 4 and can move along the axis of the cross bar 3 . The movable support block 5 is movably clamped on the upper surface of the base frame 1 and is threadedly connected to the threaded rod 4 .

[0057] The fixed support block 6 is fixed to the upper surface of the base frame 1 and is sleeved on the cross bar 3 and the threaded rod 4. It is fixedly connected to the cross bar 3 and rotatably connected to the threaded rod 4. The threaded rod 4 can rotate around its axis relative to the fixed support block 6.

[0058] When the threaded rod 4 rotates, since the fixed support block 6, the cross bar 3 and the two vertical blocks 2 are fixed to the base frame 1 as a whole, the above-mentioned whole does not rotate. Since the movable support block 5 can only move along the axis of the cross bar 3, and the movable support block 5 is threadedly connected to the threaded rod 4, the threaded rod 4 rotates forward and backward, driving the movable bracket 5 to move along the axis of the threaded rod 4.

[0059] The movable conveying frame 7 is fixed on the two movable supporting blocks 5 at the same time and moves with the movement of the movable supporting blocks 5.

[0060] The fixed conveying frame 8 is fixed on the two fixed support blocks 6 and is arranged in parallel with the movable conveying frame 7 along the Y direction.

[0061] Two groups of pulleys 9 are respectively arranged on the movable conveying frame 7 and the fixed conveying frame 8. Each group of pulleys 9 consists of two pulleys 9. Looking at a group of pulleys 9, the two pulleys 9 in the group of pulleys 9 are rotatably connected to the corresponding movable conveying frame 7 or the fixed conveying frame 8 at both ends along the X direction, and the axes of the two pulleys 9 in the group of pulleys 9 are along the Y direction.

[0062] Two transmission belts 10 are respectively mounted on the two groups of pulleys 9. The inner ring of the transmission belt 10 has teeth and meshes with two pulleys 9 in the corresponding group of pulleys 9.

[0063] The two limiting plates 11 are respectively fixed on the corresponding movable conveying frame 7 and the fixed conveying frame 8. The two conveyor belts 10 are respectively mounted on the two limiting plates 11. The outer wall of the limiting plate 11 contacts the inner wall of the conveyor belt 10 and is restricted by the limiting plate 11 to ensure that the upper surfaces of the two conveyor belts 10 remain level.

[0064] Also included is a transmission assembly for rotating the two transmission belts 10. The transmission assembly includes:

[0065] The motor support 12 is fixed on the base frame 1 .

[0066] The movable mounting seat 13 is fixed on the movable conveying frame 7. The movable mounting seat 13, the movable conveying frame 7 and the movable support block 5 can move along the Y direction as a whole.

[0067] The fixed mounting seat 14 is fixed on the fixed conveying frame 8 .

[0068] The first connecting wheel 15 is rotatably connected to the movable mounting seat 13, and the axis of the rotating shaft is along the Y direction.

[0069] The second connecting wheel (not shown) is rotatably connected to the fixed conveying frame 8, and the axis of the rotating shaft is along the Y direction.

[0070] The linkage shaft 16 has an axis along the Y direction and passes through the movable mounting seat 13, the first connecting wheel 15, the second connecting wheel and the fixed mounting seat 14. The two ends of the linkage shaft 16 are rotatably connected to the motor support 12 and the fixed mounting seat 14 respectively. The movable mounting seat 13 is provided with a hole for the linkage shaft 16 to pass through, which is recorded as the first perforation; the linkage shaft 16 does not contact the first perforation. The first connecting wheel 15 is provided with a hole for the linkage shaft 16 to pass through, which is recorded as the second perforation. In this embodiment, the shape of the second perforation is hexagonal, and the shape of the end face of the linkage shaft 16 is hexagonal, and the shapes of the two match. The first connecting wheel 15 can move relative to the linkage shaft 16 along the axis of the linkage shaft 16. At the same time, the linkage shaft 16 and the first connecting wheel 15 can rotate synchronously around the axis of the linkage shaft 16 as a whole. The linkage shaft 16 passes through the second connecting wheel. A hole is opened on the second connecting wheel for the linkage shaft 16 to pass through, which is recorded as the third through-hole. The linkage shaft 16 is fixedly connected to the third through-hole. The linkage shaft 16 passes through the fixed mounting seat 14. The fixed mounting seat 14 has a hole for the linkage shaft 16 to pass through, which is recorded as the fourth through-hole. The linkage shaft 16 is rotatably connected to the fourth through-hole through a bearing.

[0071] Therefore, the movable conveying frame 7, the movable mounting seat 13, and the first connecting wheel 15 can move as a whole along the axis of the linkage shaft 16, and the linkage shaft 16, the first connecting wheel 15 and the second connecting wheel can rotate as a whole relative to the movable mounting seat 13 around the axis of the connecting wheel 15.

[0072] The two conveyor belts 10 are respectively mounted on the first connecting wheel 15 and the second connecting wheel, and mesh with the corresponding first connecting wheel 15. Therefore, when the linkage shaft 16, the first connecting wheel 15 and the second connecting wheel rotate as a whole, the two conveyor belts 10 meshed with the first connecting wheel 15 and the second connecting wheel also rotate synchronously.

[0073] The non-rotating shaft end of the transmission motor 17 is fixed on the motor support 12 , and the rotating shaft of the transmission motor 17 is fixedly connected to the linkage shaft 16 via a coupling. The transmission motor 17 is used to drive the linkage shaft 16 to rotate.

[0074] The transmission motor 17 drives the linkage shaft 16 to rotate. Since the first connecting wheel 15 and the second connecting wheel are shaped to match the linkage shaft 16, the linkage shaft 16, the first connecting wheel 15 and the second connecting wheel rotate around the axis of the transmission motor 17 as a whole.

[0075] The conveyor belt unit also includes: two groups of beam end seats 18, each group of beam end seats 18 is composed of two beam end seats 18, and the two groups of beam end seats 18 are fixed to the movable conveyor frame 7 and the fixed conveyor frame 8 respectively. The two beam end seats 18 in each group of beam end seats 18 are fixed to the two ends of the corresponding movable conveyor frame 7 and the fixed conveyor frame 8 along the X direction. The two conveyor belt units placed side by side along the X direction can be connected to each other by relying on the beam end seats 18 and bolts. The two conveyor belt units after connection are shown in FIG. Figure 1 .

[0076] See Figure 2 , further comprising a hand-cranked component for driving the two threaded rods 4 to rotate in the same direction, the hand-cranked component comprising:

[0077] A crank handle 19, rotatably connected to one of the vertical blocks 2 and fixedly connected to one of the threaded rods 4, the axis of the crank handle 19 coinciding with the axis of the threaded rod 4. By manually turning the crank handle 19, the corresponding threaded rod 4 can be rotated.

[0078] Two driven gears 20, respectively fixed on the two threaded rods 4 and coinciding with the axes of the corresponding threaded rods 4.

[0079] A driven belt 21, sleeved on the two driven gears 20 at the same time and meshing with the two driven gears 20.

[0080] See Figure 3 , further comprising a detection component for detecting parts, the detection component comprising:

[0081] Two brackets 22, placed on the ground, the two brackets 22 arranged side by side in the Y direction, one of the brackets 22 being located on the side of the movable conveyor 7 away from the fixed conveyor 8, and the other bracket 22 being located on the side of the fixed conveyor 8 away from the movable conveyor 7. Viewed in the Y direction, the bracket 22 is in an inverted U shape, including two vertically arranged vertical parts and a horizontal part connecting the tops of the two vertical parts.

[0082] A mounting frame 23, the two ends of which are respectively fixed on the horizontal parts of the two brackets 22. 00001800000181A lifting track 24, movably clamped on the mounting frame 23, the lifting track 24 being able to move vertically relative to the mounting frame 23, being above the gap between the two conveyor unit, the lower end of the lifting track 24 being below the mounting frame 23, and the lower end of the lifting track 24 being above the conveyor belt 10. 00001820000183A rack 25, fixed on the lifting track 24, the teeth on the rack 25 being arranged vertically. 00001840000185A lifting motor 26, the non-rotating shaft end of which is fixed on the mounting frame 23, the axis of the rotating shaft of the lifting motor 26 being horizontally arranged, a height-adjusting gear (not shown) being fixed on the rotating shaft of the lifting motor 26, the height-adjusting gear meshing with the rack 25, and being able to rotate through the lifting motor 26, and combining the height-adjusting gear and the rack 25 to drive the lifting track 24 to lift. 00001860000187An X-ray machine 27, capable of emitting X-rays downward, is installed at the lower end of the lifting track 24. It can move vertically with the lifting track 24 to ensure that the emitted X-rays can penetrate the entire surface of the part. 00001880000189A photosensitive plate (not shown) is placed on the ground, in the gap between the two conveyor rack units. X-rays pass through the part, passing through the gap between the two conveyor rack units before being exposed to the photosensitive plate. Subsequently, image fusion processing technology is used to comprehensively determine the shape and position of the light-sensitive area on the plate, thereby determining the shape and location of the crack on the part. This image fusion processing technology is currently available.

[0088] The protective cover 28 is used to cover the entire detection device and is placed on the ground to prevent dust from falling on the detection unit.

[0089] The use of this device

[0090] The operator manually determines whether the spacing between the two conveyor belt units along the Y direction meets the requirements. If the operator manually determines that the spacing between the two conveyor belt units along the Y direction needs to be adjusted, the operator manually cranks the crank handle 19.

[0091] The crank 19 drives the corresponding threaded rod 4 to rotate, and simultaneously the threaded rod 4 drives another threaded rod 4 to rotate in the same direction through the driven gear 20 and the driven belt 21 thereon. So far, the two drive assemblies are driven by the two threaded rods 4 respectively.

[0092] Looking at a set of drive components, after the threaded rod 4 rotates, the threaded rod 4 drives the movable bracket 22 to move because it is threadedly connected to the movable support block 5. At the same time, the movable support block 5 can only move along the Y direction relative to the base frame 1. The other drive components operate in the same way and will not be described in detail.

[0093] The two drive assemblies simultaneously drive the movable conveyor frame 7 to move in the Y direction. The movable conveyor frame 7, the movable mounting base 13, and the first connecting wheel 15 move as a whole in the Y direction relative to the linkage shaft 16. The first connecting wheel 15 and the linkage shaft 16 produce relative movement, realizing the movement of the movable conveyor frame 7 in the Y direction and adjusting the spacing between the movable conveyor frame 7 and the fixed conveyor frame 8 in the Y direction. In addition, the conveying motor 17 drives the first connecting wheel 15 and the second connecting wheel to rotate through the linkage shaft 16. The hexagonal end surface of the linkage shaft 16 matches the shape of the first connecting wheel 15 and the second connecting wheel, ensuring that the linkage shaft 16 and the first connecting wheel 15 and the second connecting wheel rotate as a whole. The first connecting wheel 15 and the second connecting wheel also cause the conveyor belts 10 on the movable conveyor frame 7 and the fixed conveyor frame 8 to rotate in the same direction, realizing the conveyance of parts.

[0094] The X-ray machine 27 emits X-rays downward, which pass through the parts and are sensitive to light on the photosensitive plate. By analyzing the image fusion technology of the sensitive area on the photosensitive plate, it can be known whether the parts have defects, such as cracks.

[0095] When passing between two adjacent conveyor belt units, the placement of the part can be manually adjusted, such as by rotating the part 90 degrees. This ensures that X-rays can penetrate all positions of the intact part while also generating as many different exposure angles as possible on the photosensitive plate. This allows for more comprehensive image fusion, resulting in more accurate information such as defect locations. It also ensures that the edge of the part in contact with the conveyor belt 10 is also penetrated by X-rays without the X-rays passing through the conveyor belt 10.

[0096] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
