[0029] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] As Figure 1 and Figure 2 shown, a die-casting part detection device includes two mounting plates 2 supported on the ground by a bracket 1 and symmetrically arranged.

[0032] An intermittent belt conveyor 3, multiple groups of guiding components 4, and clamping components 5 are arranged between the two mounting plates 2. The guiding components 4 are used to provide guidance for the clamping components 5. The clamping components 5 include symmetrically arranged support rods 6, turntables 7, and concave clamping blocks 8. The support rods 6 are fixedly connected to the outer wall of the conveyor belt of the intermittent belt conveyor 3. The turntables 7 are rotatably connected to the side walls of the support rods 6 through shafts 11. The concave clamping blocks 8 are fixedly connected to the turntables 7 through telescopic rods 9. A spring 10 is buckled on the opposite sides of the turntables 7 and the concave clamping blocks 8. A detection component is arranged on the top of the mounting plates 2.

[0033] First, one side of the die-casting part to be detected is inserted into the concave clamping block 8 and a certain pressure is applied, causing the telescopic rod 9 to contract and the spring 10 to be elastically deformed under force. At this time, the distance between the two concave clamping blocks 8 increases. Subsequently, the other side of the die-casting part is aligned with the other concave clamping block 8 and the pressure on the telescopic rod 9 and the spring 10 is gradually reduced until both sides of the die-casting part are located within the concave clamping blocks 8. At this time, under the elastic force of the spring 10, the two concave clamping blocks 8 relatively squeeze the die-casting part, thereby realizing the clamping and fixing of the die-casting part. Utilizing the intermittent conveying characteristic of the intermittent belt conveyor 3 can synchronize the feeding and conveying of the die-casting part without stopping the machine for operation.

[0034] This device can continuously convey the die-casting part to the detection component for appearance detection by arranging the intermittent belt conveyor 3 and multiple groups of clamping components 5, improving the detection efficiency. Moreover, the use of two symmetrically arranged concave clamping blocks 8, telescopic rods 9, and springs 10 can clamp die-casting parts of different lengths, improving the flexibility of the device.

[0035] As Figure 2-4 shown, the guiding assembly 4 includes two symmetrically arranged connecting rods 12, a second shaft 13 and a guiding wheel 14. The connecting rod 12 is fixedly connected to the outer wall of the first shaft 11, and the connecting rod 12 is rotatably connected to the guiding wheel 14 through the second shaft 13.

[0036] On the opposite sides of the two mounting plates 2, guiding grooves are respectively formed. The guiding wheel 14 is in rolling fit with the inner wall of the guiding groove. The guiding groove is composed of a first U-shaped groove 15, a first inclined groove 16, a second U-shaped groove 17 and a second inclined groove 18. The first inclined groove 16 and the second inclined groove 18 are respectively connected to the opposite sides of the ends of the first U-shaped groove 15 and the second U-shaped groove 17.

[0037] After clamping the die-casting part by the concave clamping block 8, the die-casting part is conveyed from the first U-shaped groove 15 to the second U-shaped groove 17 by the intermittent belt conveyor 3. The guiding wheel 14 rolls along the guiding groove. When the guiding wheel 14 reaches the second inclined groove 18, due to the shape characteristics of the second inclined groove 18 itself, the guiding wheel 14 moves downward along the second inclined groove 18 into the second U-shaped groove 17, so that one end of the connecting rod 12 connected to the second shaft 13 rotates with the axis of the first shaft 11 as the rotation center, thereby driving the first shaft 11, the turntable 7, the telescopic rod 9, the concave clamping block 8 and the die-casting part to rotate 180 degrees, so that the top and bottom of the die-casting part can be detected; after the detection is completed, the die-casting part is removed from the concave clamping block 8, and the concave clamping block 8 continues to move with the intermittent belt conveyor 3. When the concave clamping block 8 moves to the first inclined groove 16, the shape characteristics of the first inclined groove 16 are used to enable the concave clamping block 8 to rotate 180 degrees to reset. The above operation steps are continuously repeated until all the die-casting parts to be detected are completely detected.

[0038] By providing the first U-shaped groove 15, the first inclined groove 16, the second U-shaped groove 17 and the second inclined groove 18, and using the shape characteristics of the first inclined groove 16 and the second inclined groove 18, when the guiding wheel 14 moves from the first U-shaped groove 15 to the second U-shaped groove 17 and from the second U-shaped groove 17 to the first U-shaped groove 15, the connecting rod 12 will drive the first shaft 11, the turntable 7, the telescopic rod 9 and the concave clamping block 8 to rotate 180 degrees, so that the die-casting part can be flipped during the movement process, realizing double-sided detection and further improving the detection efficiency.

[0039] As Figure 3 shown, the detection assembly includes two U-shaped frames 19 fixedly installed on the top of the mounting plate 2. On the lower surfaces of the tops of the two U-shaped frames 19, image collectors 20 are fixedly installed. The image collector 20 is preferably a camera, and the camera can be directly connected to a computer. The camera is used for image collection, and the computer is used for analysis and comparison.

[0040] Embodiment 2:

[0041] A die-casting part detection device. In this embodiment, the following improvements are made on the basis of Embodiment 1, as Figure 4 shown:

[0042] A friction ring one 21 and a friction ring two 22 are sleeved on the outer wall of the first shaft 11. The friction ring one 21 and the friction ring two 22 are respectively fixedly connected to the opposite sides of the support rod 6 and the turntable 7, and the friction ring one 21 and the friction ring two 22 are in contact and cooperate with each other.

[0043] When the friction ring two 22 rotates with the turntable 7, it contacts the surface of the friction ring one 21 to increase the friction force, thereby providing a rotational resistance for the turntable 7 and the first shaft 11. After the guide wheel 14 is worn after long-term use, the turntable 7, the concave clamping block 8, and the first shaft 11 will not shake, so that the die-casting part can always be conveyed smoothly.

[0044] By setting the friction ring one 21 and the friction ring two 22, the device uses the contact friction between the friction ring one 21 and the friction ring two 22 to provide a rotational resistance for the turntable 7, the concave clamping block 8, and the first shaft 11, so as to ensure that after the guide wheel 14 is worn, the concave clamping block 8 can still convey the die-casting part smoothly, and avoid the shaking of the die-casting part from affecting the accuracy of the detection result.

[0045] Working principle: When the device is in use, first start the intermittent belt conveyor 3. Using the intermittent conveying characteristic of the intermittent belt conveyor 3, when the conveyor belt stops moving, place the die-casting part between the two concave clamping blocks 8, and use the elastic force of the spring 10 to push the concave clamping block 8 to press the die-casting part to achieve the fixation of the die-casting part. Then the intermittent belt conveyor 3 drives the die-casting part to move below the first group of U-shaped frames 19 and the image collector 20. The image collector 20 collects an image of one side of the die-casting part and transmits the image to the computer for analysis and comparison. Subsequently, the intermittent belt conveyor 3 continues to convey the die-casting part. When the die-casting part reaches below the second group of U-shaped frames 19 and the image collector 20, during this period, the guide wheel 14 rolls along the guide groove. When the guide wheel 14 reaches the second inclined groove 18, due to the shape characteristic of the second inclined groove 18 itself, the guide wheel 14 moves downward along the second inclined groove 18 into the U-shaped groove two 17, so that one end of the connecting rod 12 connected to the second shaft 13 rotates with the axis of the first shaft 11 as the center of rotation, thereby driving the first shaft 11, the turntable 7, the telescopic rod 9, the concave clamping block 8, and the die-casting part to rotate 180 degrees, so that the image collector 20 can collect an image of the other side of the die-casting part to improve the accuracy of the detection; after the detection is completed, take the die-casting part off the concave clamping block 8, and the concave clamping block 8 continues to move with the intermittent belt conveyor 3. When the concave clamping block 8 moves to the first inclined groove 16, the shape characteristic of the first inclined groove 16 is used to make the concave clamping block 8 rotate 180 degrees to reset. Continuously repeat the above operation steps until all the die-casting parts to be detected are completely detected.

[0046] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of various changes or substitutions thereof, and these should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
