[0038] Example 3

[0039] like Figure 1-Figure 4 As shown, a bottom plate 42 is provided at the bottom end of 13 away from the placement seat 31, and a support rod 43 is connected to the four corners of the bottom plate 42 at the slots, and the other end of the support rod 43 is slidably connected to the inner slot of the slide chute body 44, and the other end of the slide chute body 44 is fixedly connected to the four corners of the bottom end of the placement seat 31, and a mounting groove 49 is slotted at the middle of the bottom end of the placement seat 31, and a connecting plate 47 is connected to the inner side of the mounting groove 49, and the middle bottom end of the connecting plate 47 is fixed A pneumatic pump body 46 is fixedly connected, and second fixing bolts 48 are threadedly connected at the four corner grooves of the connecting plate 47. One end of the second fixing bolt 48 is threadedly connected to a placement seat 31. A bottom plate 42 is provided at the bottom end of the placement seat 31. The middle part of the bottom end of the bottom plate 42 is threadedly connected to the first fixing bolt 41. A fixing groove 45 is threadedly connected to one end of the first fixing bolt 41. The fixing groove 45 is slotted and arranged in the middle part of one end of the pneumatic pump body 46.

[0040] In this embodiment, the bottom plate 42 is grooved at the four corners with predetermined grooves that can be inserted into the top of the support rod 43, and the support rod 43 can slide in the predetermined grooves opened in the slide groove body 44. The placement seat 31 provides a fixed effect for the slide groove body 44, and the slide groove body 44 provides the placement seat 31 with an anti-sway effect at the four corners. The placement seat 31 can be connected to the remaining components through the installation groove 49 provided by the groove. The connecting plate 47 can be inserted into the installation groove 49. When the connecting plate 47 and the installation groove 49 form a snap connection, the placement seat 31 and the connecting plate 47 will form a relative snap state. The connecting plate 47 provides a fixed effect for the air pressure pump body 46, and the air pressure pump body 46 can perform compression and lifting effects on itself. The second fixing bolt 48 can be connected to the connecting plate 47 by a screwing operation, and the first When the second fixing bolts 48 are being screwed, the connecting plate 47 and the placement seat 31 can be relatively fixedly connected. Since the connecting plate 47 and the air pressure pump body 46 are in a fixed connection state, when the air pressure pump body 46 is lifted or lowered, it will provide support for the placement seat 31 and enable it to be lifted or lowered synchronously. The first fixing bolt 41 can be connected to the base plate 42 by a screwing operation, and the first fixing bolt 41 can be connected to the end of the air pressure pump body 46 with a fixing groove 45 when being screwed. When the first fixing bolt 41 is connected to the fixing groove 45 and the base plate 42, the air pressure pump body 46 will be in a relatively connected state with the base plate 42, and the support rod 43 will be inserted into the slot provided in the base plate 42, thereby inserting it into the base plate 42 to maintain the overall stability of the placement seat 31.

[0041] Working principle:

[0042] like Figure 1-Figure 7As shown, when the test plate needs to be split, the test plate can be placed in the middle of the placement seat 31. At this time, the servo motor 35 can be operated according to the diameter of the test plate. When the servo motor 35 is operated, it will drive the bidirectional threaded rod 34 connected thereto to rotate. During the rotation of the bidirectional threaded rod 34, the driving wheel 36 connected to one side will be driven to rotate. During the rotation of the driving wheel 36, the toothed belt 37 will be driven to operate. During the operation of the toothed belt 37, the driven wheel 38 will be driven to rotate. During the rotation of the driven wheel 38, the bidirectional threaded rod 34 connected thereto will be driven to rotate. During the synchronous rotation of the side bidirectional threaded rod 34, the moving seats 33 arranged at the two sides will move in the shifting grooves 32 opened in the placing seat 31 in relative directions. When the moving seat 33 moves to a suitable position, the adjusting bolt 24 can be rotated according to the thickness of the test plate. During the rotation of the adjusting bolt 24, pressure will be applied to or released from the pressing sheet 25. During the movement of the pressing sheet 25, it can be pressed on the two sides of the test plate. When the pressing sheet 25 is subjected to pressure, the moving tube 22 will move in the limiting tube 21. During the movement of the moving tube 22, a certain pressure will be applied to the spring 23 arranged in the limiting tube 21, and through The reaction force applied by the spring 23 makes it stably pressed on both sides of the test plate. After the pressing is completed, the moving rail 12 provided on the support frame 11 can be used to make the cutting assembly 13 find its position by itself and cut the test plate. When the height of the placement seat 31 needs to be adjusted, the air pressure pump body 46 can be enabled to operate. When the air pressure pump body 46 is in operation, it will lift itself up and down, and in the process of lifting and lowering, it will apply a certain relative pressure to the bottom plate 42 to make the placement seat 31 lift and lower. In the process of lifting and lowering, the support rod 43 will slide in the predetermined slot opened by the slide trough body 44, and the placement seat 31 will be lifted and lowered during the sliding process of the support rod 43. 1 will perform continuous lifting operation and maintain its stability during use. When the air pressure pump body 46 needs to be replaced, the placement seat 31 on the bottom plate 42 can be disassembled at this time, and the support rod 43 is separated from the slot on the bottom plate 42. At this time, the first retaining bolt 41 will be disconnected from the retaining groove 45 slotted at the end of the air pressure pump body 46 during the screwing process. After the release, the second retaining bolt 48 at the connection between the second retaining bolt 48 and the connecting plate 47 can be disconnected by screwing. After the release, the bottom plate 42 and the connecting plate 47 will be disconnected. At this time, the air pressure pump body 46 connected with the connecting plate 47 can be taken out and replaced or repaired.
