Description

Technical field:

[0001] The utility model relates to the technical field of wheel hub processing equipment, and more specifically to a device for detecting mold misalignment of aluminum alloy cast rotary wheel blanks. Background technology:

[0002] With the lightweight wheels and the improvement of wheel performance requirements, spinning technology is becoming more and more popular. However, the spinning capacity is high, and often a cast spinning wheel is equipped with several sets of casting molds and one set of spinning molds. However, the blanks produced by different casting molds have different degrees of mold mismatch. During spinning, the mold mismatch of the blanks produced by different casting molds is compensated by the spinning program. Therefore, the cast blanks need to be manually inspected by employees to check whether they meet the requirements. The blanks that meet the requirements and those that do not meet the requirements are classified and placed on pallets to facilitate the subsequent classification and spinning production of the blanks.

[0003] However, employees manually inspect and classify rough parts, which is inefficient and labor-intensive. Utility model content:

[0007] A laser displacement sensor is fixed on the left side of the middle support plate, and the sensing end of the laser displacement sensor faces the outer side wall of the wheel hub.

[0008] Four parting lines are formed on the outer side wall of the wheel hub. The parting lines are evenly distributed on the outer side wall of the wheel hub with the central axis of the wheel hub as the center. The sensing end of the laser displacement sensor faces the parting lines.

[0009] An intermediate support block is fixed in the middle of the top surface of the rotating plate, an intermediate positioning column is fixed in the middle of the top surface of the intermediate support block, and the intermediate positioning column is inserted in the central through hole of the wheel hub.

[0017] For example, see Figures 1 to 3 The device for detecting mold misalignment of an aluminum alloy cast rotary wheel blank shown in the figure comprises a conveying roller 10 extending forward and backward, a lower support frame is provided at the middle of the conveying roller 10, an intermediate support plate 20 is fixed to the top surface of the lower support frame, the intermediate support plate 20 is flush with the top surface of the electric roller installed in the conveying roller 10, a rotating motor 21 is fixed to the lower part of the intermediate support plate 20, the top end of the output shaft of the rotating motor 21 extends out of the intermediate support plate 20 and is fixed with a rotating plate 22, and a wheel hub 100 to be detected is placed on the rotating plate 22;

[0018] A laser displacement sensor 30 is fixed to the left side of the middle support plate 20 , and a sensing end of the laser displacement sensor 30 faces the outer side wall of the wheel hub 100 .

[0019] Furthermore, four parting lines 101 are formed on the outer wall of the hub 100. The parting lines 101 are evenly distributed on the outer wall of the hub 100 with the central axis of the hub 100 as the center. The parting lines 101 are formed when the hub 100 is cast using four side molds.

[0020] The sensing end of the laser displacement sensor 30 faces the parting line 101 .

[0021] Furthermore, a middle support block 23 is fixed to the middle of the top surface of the rotating plate 22 , a middle positioning column 24 is fixed to the middle of the top surface of the middle support block 23 , and the middle positioning column 24 is inserted into the central through hole of the wheel hub 100 .

[0022] Furthermore, a classification conveying roller 40 is provided at the right portion of the middle support plate 20 , and a plurality of electric rollers are fixed on the classification conveying roller 40 , and the top surfaces of the electric rollers are flush with the top surfaces of the electric rollers.

[0023] Furthermore, a horizontal fixing plate 1 is fixed on the left side wall of the middle supporting plate 20 , and the laser displacement sensor 30 is fixed on the top surface of the horizontal fixing plate 1 .

[0024] Furthermore, a protective elastic sleeve 241 is fixed on the outer wall of the middle positioning column 24, and the protective elastic sleeve 241 is inserted into the central through hole of the wheel hub 100. The outer wall of the protective elastic sleeve 241 is tightly attached to the inner wall of the central through hole of the wheel hub 100, and the bottom end of the protective elastic sleeve 241 is pressed against the top surface of the middle support block 23.

[0025] Furthermore, the top surface of the middle positioning column 24 is screwed with an upper cover 242 , and the bottom surface of the upper cover 242 is pressed against the top surface of the protective elastic sleeve 241 .

[0026] The laser displacement sensor 30 is electrically connected to the control host through an electrical connection line;

[0027] When using it, the wheel hub 100 is first placed on the top surface of the rotating plate 22, the middle positioning column 24 is inserted into the central through hole of the wheel hub 100, and the outer wall of the protective elastic sleeve 241 is closely attached to the inner wall of the central through hole of the wheel hub 100, so that it is not easy to be knocked and damaged.

[0028] Then, the rotating plate 22 is rotated by the rotating motor 21. When the sensing end of the laser displacement sensor 30 senses one of the parting lines 101, it indicates that it has moved into position. Then, the rotating motor 21 (which is a servo motor) is rotated forward by a certain angle again, so that the rotating plate 22 is rotated by a certain angle (such as 15°), so that the laser displacement sensor 30 can detect the distance of the outer wall of the wheel hub 100 on one side of the parting line 101. Then, the rotating motor 21 is operated again, so that the rotating plate 22 is rotated in the opposite direction by a certain angle, such as 30°, so that the outer wall of the wheel hub 100 on the other side of the parting line 101 is detected in distance, and the detected data is compared with the set data. Then, the rotating motor 21 is operated again, so that another parting line 101 of the wheel hub 100 is sensed by the laser displacement sensor 30, and then the outer wall of the wheel hub 100 on both sides thereof is detected in distance. In this way, the positions on both sides of the four parting lines 101 are detected in turn. All distances meet the requirements, indicating that the requirements are met.

[0029] The wheel hub 100 is taken out from the middle support plate 20 by the material taking device and placed at the rear of the conveyor roller 10. The wheel hub 100 can be conveyed backward to the subsequent equipment by the rotation of the electric roller on the wheel hub 100.

[0030] For unqualified products, they can be placed in the classification conveying roller 40, and moved to the unqualified area through the rotation of the corresponding electric roller, so that the classified placement is achieved, which is convenient for subsequent spinning processing and has a good classification effect.

[0031] The wheel hub 100 can be placed and taken by installing a robot on the left side of the middle support plate 20 of the present embodiment to achieve grasping and placement, or it can be manually carried.

Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
