Description

Technical Field

[0001] The invention relates to the technical field of die casting detection, and in particular to a large integrated die casting rotary double-station manual detection platform. Background Art

[0002] Die castings are metal parts made by die casting.

[0003] Traditionally, the surface smoothness inspection of die castings includes visual camera inspection and laser reflection inspection. When laser reflection is used for inspection, the laser reflection angle needs to be calibrated at all times to ensure that the reflected laser is consistent with the receiving sensor.

And because the sliding shell 18 moves in an arc, the traction column 27 can move forward and backward in the slide groove 25.

[0035] A lower through-shaft 33 and an upper through-shaft 34 are provided inside the sliding shell 18, the infrared receiving probe 29 is sleeved on the lower through-shaft 33, and the infrared transmitting probe 28 is sleeved on the upper through-shaft 34; a lower column 32 is provided on the right side surface of the infrared receiving probe 29, an upper column 31 is provided on the right side surface of the infrared transmitting probe 28, and a connecting rod 30 is movably sleeved between the upper column 31 and the lower column 32; the line between the lower through-shaft 33 and the upper through-shaft 34 is parallel and equal to the line between the upper column 31 and the lower column 32 (such as Fig. 9 As shown), through this parallel and equal design, the infrared transmitting probe 28 and the infrared receiving probe 29 can swing up and down synchronously.

[0036] A large gear 35 is coaxially sleeved on the surface of the infrared emitting probe 28, and a support shaft 40 is also provided inside the sliding shell 18. A gear column 36 is sleeved on the surface of the support shaft 40, and the right side of the gear column 36 is meshed and connected with the large gear 35; a fixed L frame 2 39 is installed on the inner wall of the sliding shell 18, and a motor 2 38 is fixedly installed above the fixed L frame 2 39. The output shaft sleeve of the motor 2 38 is provided with a worm 37, and the worm 37 is rotatably connected with the left side of the gear column 36 (such as Fig. 9 As shown), the worm 37 is used for driving, which can ensure that when the motor 2 38 is not started, the infrared transmitting probe 28 and the infrared receiving probe 29 are in a locked state.

[0037] Example 4 like Figure 1 , 2 As shown, a level 10 is provided on both sides of the outer shell 1, and a support rod 11 is provided at the bottom of the outer shell 1; a rotating shaft 13 is provided at the bottom of the adjusting turntable 7, and the adjusting turntable 7 is rotatably connected to the rotating table 4 through the rotating shaft 13; an electric telescopic rod 8 is provided at the bottom of the rotating table 4 and on one side of the adjusting turntable 7, and a locking hole 14 that can match the output shaft of the electric telescopic rod 8 is opened on the surface of the adjusting turntable 7.

[0038] According to the above embodiments 1-4, the working principle of the present invention is: start the reduction motor 15 to rotate the rotating table 4 to a suitable angle to adapt to the mechanical arm of the feeding machine. After adjusting the angle of the adjusting dial 7, start the electric telescopic rod 8 to make the output shaft of the electric telescopic rod 8 stuck in the locking hole 14, thereby locking the adjusting dial 7 (such as Figure 2 as shown).

[0039] At the same time, the testing machines 3 on both sides are started to perform smoothness tests on both sides of the plate 2. During the smoothness test of the plate 2, the motor 1 22 drives the screw rod 16 to rotate through the synchronous belt 23, and the rotation of the screw rod 16 can drive the swing block 26 to move left or right (such as Figure 6 As shown, the limit rod 20 is used to ensure the smooth movement of the swing block 26). There is a traction column 27 below the swing block 26. The traction column 27 squeezes the slide groove 25 to drive the sliding shell 18 to move left or right. Since the sliding shell 18 is sleeved on the arc rod 17, the sliding shell 18 will move at a deflection angle, thereby ensuring that a wider range of the plate 2 can be horizontally scanned and detected.

[0040] The infrared emitting probe 28 and the infrared receiving probe 29 inside the sliding shell 18 can swing up and down, so that a larger range of the plate 2 can be longitudinally scanned and detected. Among them, the infrared emitting probe 28 and the infrared receiving probe 29 can swing up and down by the control of the motor 2 38 (such as Fig. 9 As shown). The second motor 38 can drive the infrared emitting probe 28 to swing up and down through the worm 37, the gear column 36 and the large gear 35; and through the transmission of the connecting rod 30, the infrared receiving probe 29 can synchronously follow the infrared emitting probe 28 to swing up and down, so as to ensure that the scanning points and track points on the plate 2 can be stably detected.
