Description

Technical Field

[0001] The invention relates to the field of ray detection equipment, and in particular to a high-efficiency ray detection equipment for cylindrical parts. Background Art

[0002] The principle of X-ray detection in industry is that when X-rays are absorbed by a substance, the molecules that make up the substance can be decomposed into positive and negative ions, which is called ionization. The number of ions is proportional to the amount of X-rays absorbed by the substance. Ionization is produced by air or other substances, and the amount of X-rays can be calculated by measuring the degree of ionization with an instrument. The imager converts it into a digital signal, and then restores it to an image through computer-aided software for image judgment, annotation, storage, etc.

The workpiece bracket 6 includes a plurality of rotating support seats 61 arranged in a row, and the rotating support seats 61 can rotate to drive the workpiece to rotate. At least two auxiliary brackets 62 are correspondingly arranged around each of the rotating support seats 61, which are used to assist in supporting the workpiece to be placed and tilted. The docking roller bed 3 is provided with a rotary drive mechanism 7 that drives the plurality of rotating support seats 61 to rotate around their own axes. The ray emitting mechanism 4 is located on one side of the docking roller bed 3, and the ray receiving mechanism 5 is located on the other side of the docking roller bed 3, and the ray emitting tube 41 of the ray emitting mechanism 4 and the receiving screen 51 of the ray receiving mechanism 5 always maintain a positive relationship, so that the rays emitted by the ray emitting tube 41 can be received by the receiving screen 51.

[0031] like Figure 3As shown, the workpiece bracket 6 in this embodiment also includes a bottom plate 63, and a plurality of the slewing support seats 61 are arranged in a row at equal intervals on the bottom plate 63, and a slewing gear 64 is coaxially connected to the lower part of each slewing support seat 61, and a transmission gear 65 for meshing transmission is arranged between any two of the slewing gears 64. The bottom plate 63 is also provided with a driving gear 66 meshing with one of the transmission gears 65 or the slewing gear 64, and the rotation of the driving gear 66 can drive all the slewing support seats 61 to rotate synchronously in the same direction. The upper part of the driving gear 66 has a transmission shaft hole 67 that cooperates with the slewing drive mechanism 7. A cover plate 68 is arranged on the top of the bottom plate 63, and the auxiliary bracket 62 is arranged on the cover plate 68.

Above the corresponding rotary support seat 61, each of the auxiliary brackets 62 has two claw handles 602 distributed in an eight-shaped shape, and the claw handles 602 on two adjacent auxiliary brackets 62 can form a diamond frame for auxiliary support of the limited workpiece.

[0034] In this embodiment, the claw handle 602 is flipped and connected on the connecting seat 601, and the flipping angle is limited from the horizontal direction to the vertical direction. The function of this structure is that the claw handle 602 can be flipped up vertically when taking and placing items, making it easier to take and place items.

The second conveying roller shaft 32 is also provided with a second sprocket 34, and the docking roller bed bracket 31 is also provided with a second driving motor 35 for driving the second sprocket 34 on each second conveying roller shaft 32 to move synchronously.

The docking roller bed support 31 is also provided with two cylinder-driven second stop blocks 37, and the distance between the two second stop blocks 37 is equal to the length of one workpiece bracket 6. When the workpiece bracket 6 is sent into the lead room 1 and reaches the predetermined position on the docking roller bed 3, the two second stop blocks 37 extend to limit the workpiece bracket 6, which provides accurate positioning for the connection of the rotary drive mechanism 7 on the one hand, and prevents the workpiece from shifting during the radiation detection process on the other hand.

[0039] like Figure 6 As shown, the rotary drive mechanism 7 includes a bottom support plate 71 arranged on the docking roller bed bracket 31. The bottom support plate 71 is provided with a vertical plate 72. The vertical plate 72 is provided with a guide rail slider mechanism in the vertical direction.

The horizontal stroke of the first cross slide 42 is not less than the length of the workpiece bracket 6, and the vertical stroke of the first cross slide 42 is not less than the length of the workpiece to be measured, which can ensure that the workpieces entering the lead room 1 can be irradiated by the rays.

[0041] like Figure 8As shown, the ray receiving mechanism 5 is arranged opposite to the ray emitting mechanism 4, that is, the ray emitting mechanism 4 is arranged on the front wall of the lead room 1, and the ray receiving mechanism 5 is arranged on the rear wall of the lead room 1, and vice versa. The ray receiving mechanism 5 includes a second cross slide 52, wherein the second cross slide 52 has the same structure as the first cross slide 42, and the second cross slide 52 is driven synchronously with the first cross slide 42. The difference is that the second cross slide 52 is also provided with a Z-axis motion mechanism 53, which can make the receiving screen 51 move towards the ray emitting tube 41, which is more conducive to imaging, so the receiving screen 51 can achieve three-axis movement.
