Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a precision positioning fixture for an irradiation device, comprising a working frame 1 and a hollow box 3. An irradiator body 2 is disposed on the inner top wall of the working frame 1. An electric push rod 4 is fixedly connected to the inner wall of the hollow box 3. A transmission block 5 is fixedly connected to the output end of the electric push rod 4. A slider 6 is fixedly connected to the lower surface of the transmission block 5. The outer wall of the slider 6 is slidably connected to the inner wall of the hollow box 3. A connecting plate 7 is rotatably connected to the upper outer wall of the transmission block 5. A slide block 8 is rotatably connected to the inside of the connecting plate 7. The inner wall of the slide block 8 is slidably connected to... There is a slide rail 9, the upper surface of which is fixedly connected to the inner top wall of the hollow box 3. The outer wall of the slide block 8 is slidably connected to the inside of the hollow box 3. An L-shaped clamping block 10 is fixedly connected to the front outer wall of the slide block 8. A moving component is provided on the lower surface of the hollow box 3. The moving component includes an electric slide table 11, the upper surface of which is fixedly connected to the lower surface of the hollow box 3. A slide rail 12 is slidably connected to the inner wall of the electric slide table 11. A support plate 13 is fixedly connected to the lower surface of the slide rail 12.

[0024] Specifically, the irradiator body 2 irradiates the sample to be treated. The electric push rod 4 drives the transmission block 5 to slide. The slider 6 slides on the transmission block 5 to achieve the effect of offset limitation. The connecting plate 7 transmits power to the slide block 8 through the transmission block 5. The slide block 8 slides on the slide rail 1 to achieve the effect of offset limitation. The interior of the hollow box 3 supports the slide block 8, thereby preventing the L-shaped clamp 10 from shifting. The L-shaped clamps 10 on both sides of the hollow box 3 move towards the center to center and clamp the sample, so that the center of the sample is in the best alignment with the central axis of the irradiation source. The electric slide table 11 slides on the outer wall of the slide rail 2 to adjust the position of the sample.

[0025] Reference Figure 1 The outer wall of the support plate 13 is slidably connected to the inner wall of the working frame 1, and the lower surface of the support plate 13 is fixedly connected to the telescopic rod 14, and the lower surface of the telescopic rod 14 is fixedly connected to the inner bottom wall of the working frame 1.

[0026] Specifically, the inner wall of the working frame 1 achieves the initial offset restriction effect on the sliding of the support plate 13, and the telescopic rod 14 further restricts the offset of the sliding of the support plate 13, while also achieving the range restriction effect on the support plate 13.

[0027] Reference Figure 3 A motor 15 is fixedly connected to the upper surface of the working frame 1, and a worm gear 16 is fixedly installed at the output end of the motor 15. A worm wheel 17 is meshed with the tooth end of the worm gear 16, and a lead screw 18 is fixedly connected inside the worm wheel 17. Fixed plates 19 are rotatably connected to both ends of the lead screw 18, and the lower surface of the fixed plates 19 is fixedly connected to the inner bottom wall of the working frame 1. A connecting block 20 is threadedly connected to the outer wall of the lead screw 18, and a transmission plate 21 is rotatably connected to both outer walls of the connecting block 20. A fixed seat 22 is rotatably connected inside the transmission plate 21, and the upper surface of the fixed seat 22 is fixedly connected to the lower surface of the support plate 13.

[0028] Specifically, the working frame 1 fixes the motor 15, the motor 15 drives the worm gear 16, the worm wheel 17 transmits power to the lead screw 18 through the worm gear 16, the fixed plate 19 supports the rotation of the lead screw 18, the connecting block 20 transmits power to the transmission plate 21 through the lead screw 18, and as the transmission plate 21 rotates, it lifts the fixed seat 22 upward or pulls the fixed seat 22 downward, thereby driving the support plate 13 to move up and down.

[0029] Working principle: When using this fixture, the sample to be processed is placed on the surface of the hollow box 3. The electric push rod 4 is activated to drive the transmission block 5 and the slider 6 to slide. The transmission block 5 drives the connecting plate 7 to move to the left. Under the action of the short rod set on the lower surface of the slide block 8, the connecting plate 7 drives the slide block 8 to slide backward. The slide rail 9 limits the sliding of the slide block 8. The slide block 8 drives the L-shaped clamping block 10 to move backward to clamp and fix the sample. At the same time, the irradiator body 2 is activated to irradiate the sample. When the sample length is long, the electric slide table 11 is activated to slide on the outer wall of the slide rail 12, causing the hollow box 3 and the fixed sample to move left and right, thereby improving the uniformity of sample processing. The motor 15 drives the worm gear 16 and worm wheel 17. The motor 15 drives the lead screw 18 to rotate, and the fixed plate 19 supports the rotation of the lead screw 18. The lead screw 18 drives the connecting block 20 to move to the left, which in turn drives the transmission plate 21 to rotate to the right. The transmission plate 21 lifts the fixed seat 22 to move upward, which in turn drives the support plate 13 to move upward on the inner wall of the working frame 1, thereby adjusting the height of the sample. The telescopic rod 14 is used to limit the up and down movement of the support plate 13. During use, this fixture not only centers and clamps the sample to provide precise positioning for irradiation treatment, so that the same type of sample can be placed in the same ideal position each time it is processed, but also allows the operator to easily place and remove the sample by adjusting the support plate 13 to a suitable height when loading and unloading the sample.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
