[0032] A sliding hole is provided at the inner upper end of the support block 2, in which a guide slide plate 11 is slidably provided, a transmission positioning mechanism is provided between the guide slide plate 11 and the plurality of rotating rods 8, and the transmission positioning mechanism includes a transmission chain 12, the rear ends of the plurality of rotating rods 8 are fixedly sleeved with a first sprocket 13, a driving rod 14 is rotatably penetrated inside the guide slide plate 11, a second sprocket 15 is fixedly sleeved on the rod wall of the driving rod 14, a transmission sleeve of the transmission chain 12 is disposed on the outer sides of the first sprocket 13 and the second sprocket 15, transmission grooves for cooperating with the transmission of the transmission chain 12 are provided at the upper ends of both sides of the support block 2, a positioning bolt 16 is penetrated by the internal thread of the second sprocket 15, and a threaded groove for cooperating with the positioning bolt 16 is provided inside the guide slide plate 11.

[0033] Before inspecting the aluminum alloy casting after forming, the device is placed at the outlet end of two adjacent production lines, and the two-way screw rod 3 is driven to move the two sliders 4 at the same time, and the cross plate 5 is driven to move under the support of the moving block 24. At this time, the positioning columns 6 on both sides are adjusted in lateral position and matched with the end of the production line. During the position adjustment of the positioning columns 6, the guide plate 11 drives the second sprocket 15 to slide in the slide hole. After the left production line starts to form the casting, it gradually moves from the production line to the multiple positioning columns 6, and then the driving rod 14 is rotated to rotate the second sprocket 15. At this time, the transmission chain 12 drives the multiple first sprockets 13 and the second The sprockets 15 rotate at the same time, and the two rotating rods 8 drive the clamps 9 to start rotating synchronously, and the left clamp 9 drives the pressure block 10 to press the casting and start testing, and then the positioning bolt 16 is connected to the threaded groove to fix the position of the transmission chain 12. At the same time, the gradually on the right production line can be placed on the multiple positioning columns 6 on the right. After the inspection of the left gradually is completed, the driving rod 14 is reversed, so that the right clamp 9 starts to rotate and approaches to squeeze the right gradually. At this time, the left casting can be taken and the other gradually can be reinstalled, so that the disassembly and assembly positioning can be completed during the casting inspection process, thereby improving the operation convenience and detection efficiency of the inspection fixture.

[0034] Example 2

[0035] Embodiment 2 is based on Embodiment 1 in order to fix the working position of the second sprocket 15 after the positions of the two transverse plates 5 are adjusted, such as Figure 1-2 and Figure 4 As shown, the cross-section of the guide slide 11 is I-shaped, and a plurality of spaced positioning holes are provided at the inner upper end of the support block 2 and on both sides of the sliding hole. A positioning rod 17 is slidably penetrated by the inner lower end of the guide slide 11. The positioning rod 17 is a U-shaped positioning rod, and both ends of the positioning rod 17 are inserted into the positioning hole. A first spring 18 is fixed between the positioning rod 17 and the guide slide 11, and two symmetrically arranged limit rods 19 are slidably penetrated by the rod wall of the positioning rod 17, and the limit rod 19 is fixedly connected to the guide slide 11.

[0036] Before adjusting the setting position of the horizontal plates 5 on both sides, the positioning rod 17 can be pulled so that the positioning rod 17 slides on the limit rod 19 and the first spring 18 is stretched at the same time. At this time, the positioning rod 17 is pulled out of the positioning hole. When the working position of the second sprocket 15 is adjusted, the positioning rod 17 is released, and the elastic force of the first spring 18 is restored, so that the positioning rod 17 is inserted into the positioning hole again, ensuring that the position of the second sprocket 15 is fixed, so that the transmission work between the transmission sprocket 12, the first sprocket 13 and the second sprocket 15 can be carried out stably.

[0037] Example 3

[0038] Embodiment 3 is based on Embodiment 1.

Figure 1 and Figure 3 As shown, a rotating block 20 is fixedly sleeved on the middle end of the rod wall of the bidirectional screw rod 3, an outer fixed sleeve of the rotating block 20 is provided with an outer gear ring 21, sliding grooves are opened on both sides of the inner wall of the operating chamber, and the inner walls of the two sliding grooves are jointly fixed with an inner gear ring 23 through a second spring 22, and the inner gear ring 23 is sleeved on the outer side of the outer gear ring 21.

[0039] Before the bidirectional screw rod 3 rotates, the inner gear ring 23 is pushed so that the inner gear ring 23 slides in the slide groove and squeezes the second spring 22. At this time, the rotating block 20 can drive the bidirectional screw rod 3 to rotate. After the bidirectional screw rod 3 rotates, the inner gear ring 23 is released. Under the elastic force of the second spring 22, the inner gear ring 23 can be sleeved on the outer side of the outer gear ring 21 to limit the rotation of the rotating block 20, so as to avoid the rotating block 3 from being accidentally pushed and driving the bidirectional screw rod 3 to rotate, thereby ensuring the stability of the inspection tool during use.
