[0029] Example 1

[0030] In order to solve the technical problems in the background technology, the following valve body positioning device based on human-machine collaboration is provided:

[0031] Combine Figure 1-Figure 5 As shown, the valve body positioning device based on human-machine collaboration provided by the present invention includes a base 1, a vertical connecting block 11 is fixedly installed on the top of the base 1, a connecting shell 12 is movably penetrated in the vertical direction on the outside of the connecting block 11, a placement plate 2 is fixedly installed on the top of the connection shell 12, a valve seat 3 is placed on the top of the placement plate 2, and limit plates 4 are symmetrically slidably installed on both sides of the placement plate 2 in the width direction thereof, and the limit plates 4 are slidably installed on the placement plate 2 along the width direction of the placement plate 2;

[0032] The base 1 is provided with sliding grooves 13 on both sides of the connecting block 11. Sliding blocks 14 are slidably mounted in the sliding grooves 13 along the length direction of the base 1. Both sides of the connecting shell 12 are hinged with hinge rods 121. The other ends of the two hinge rods 121 are hinged to the two sliding blocks 14 respectively.

[0033] A transmission mechanism 5 is installed on the sliding block 14, and the other end of the transmission mechanism 5 is connected to the two limit plates 4 located above the sliding block 14. When the connecting shell 12 slides downward along the connecting block 11, the two limit plates 4 are brought close to each other through the transmission mechanism 5. A fixing member 6 connected to the connecting block 11 is installed on the connecting shell 12, which is used to fix or cancel the fixation between the connecting shell 12 and the connecting block 11. In this embodiment, a mechanical arm is fixedly installed on one side of the base 1, and a pneumatic clamp for clamping the valve seat 3 is installed at the free end of the mechanical arm to facilitate loading and unloading of the valve seat 3. When assembling the gate valve, the valve seat 3 is placed on the placement plate 2 and the two ends of the valve seat 3 are respectively located between the opposite sides of the two limit plates 4 on both sides of the placement plate 2 in the width direction, and the valve seat 3 is applied. The downward pressure is applied, thereby achieving a downward pressure effect on the placement plate 2. At this time, the connecting shell 12 slides downward along the connecting block 11, and the two hinged rods 121 rotate around their own hinge points on both sides of the connecting shell 12. The other ends of the two hinged rods 121 rotate between the two sliding blocks 14, so that the sliding blocks 14 can slide in the sliding groove 13 in the direction away from the connecting block 11, so that the two limit plates 4 are close to each other, so that the four limit plates 4 can all contact with the valve seat 3 and limit the valve seat 3. At this time, the connecting shell 12 and the connecting block 11 are fixed by the fixing member 6, so that the valve seat 3 can be positioned, thereby facilitating the assembly between the gate plate and the valve seat 3, which is beneficial to the assembly of the gate valve, thereby improving the assembly efficiency of the gate valve.

[0034] Example 2

[0035] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0036] In this embodiment, the transmission mechanism 5 includes a shell 51, a vertical rod 52 and a connecting rod 53. The bottom of the limit plate 4 extends to the bottom of the placement plate 2. The two limit plates 4 are fixedly installed with a vertical shell 51 on the side away from each other. The bottom of the shell 51 is movably penetrated by the vertical rod 52. The bottom of the vertical rod 52 can fit with the top of the base 1. The two sides of the sliding block 14 are hinged with connecting rods 53. The other ends of the two connecting rods 53 are respectively hinged with the two vertical rods 52. When in use, the placement plate 2 is pressed down to make the sliding block 1 When sliding in the sliding groove 13 in the direction away from the connecting block 11, the two connecting rods 53 rotate around their own hinge points on both sides of the sliding block 14, and the other ends of the two connecting rods 53 rotate between the two vertical rods 52 respectively. The vertical rods 52 move through the bottom of the shell 51, so that the two limiting plates 4 can slide closer to each other on the placement plate 2 through the two shells 51. During this period, when the placement plate 2 moves downward, it drives the shell 51 to move downward, and the vertical rods 52 slide into the shell 51 without affecting the downward movement of the placement plate 2.

[0037] In this embodiment, the fixing member 6 includes a fixing rod 61 that is horizontal and threadedly penetrates the connecting shell 12. One end of the fixing rod 61 penetrates the connecting shell 12 and can conflict with the connecting block 11. When in use, a force is applied to the fixing rod 61 to rotate it on the connecting shell 12. The fixing rod 61 moves spirally on the connecting shell 12 so that one end of the fixing rod 61 penetrates the connecting shell 12 and conflicts with the connecting block 11, thereby achieving the fixation between the connecting block 11 and the connecting shell 12, and the operation is simple.

[0038] In this embodiment, the two limiting plates 4 are fixedly installed with limiting blocks 7 on the side close to each other. By setting the limiting blocks 7, when assembling the gate valve, the valve seat 3 is placed on the placement plate 2 and a downward pressure is applied to the valve seat 3 so that the four limiting plates 4 are in contact with the valve seat 3. The two ends of the valve seat 3 are limited by the four limiting blocks 7, thereby further improving the limiting effect of the valve seat 3, which is beneficial to the assembly of the gate valve.

[0039] Example 3

[0040] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following content:

[0041] The cam 42 is fixedly mounted on the two guide rods 42 and is close to the end of the connecting shell 12, and the limit block 7 is fixedly mounted on the movable plate 43. The sliding plate 41 is provided with an adjusting member 44 connected to the movable plate 43, which is used to make the movable plate 43 slide or stop sliding along the axial direction of the guide rod 42. By setting the limit plate 4 to include the sliding plate 41, the guide rod 42, the movable plate 43 and the adjusting member 44, the movable plate 43 is slid along the axial direction of the guide rod 42 by the adjusting member 44 during use, so that the distance between the limit blocks 7 on the two limit plates 4 on one side of the length direction of the placing plate 2 can be adjusted, so that the distance between the limit blocks 7 on the two limit plates 4 on one side of the length direction of the placing plate 2 can be adjusted according to the size of the assembled valve seat 3, thereby improving applicability.

[0042] In this embodiment, the adjusting member 44 includes an adjusting rod 441 which is horizontal and has a thread passing through the sliding plate 41. One end of the adjusting rod 441 passes through the sliding plate 41 and is rotatably connected to the movable plate 43. When in use, a force is applied to the adjusting rod 441 to make it move spirally on the sliding plate 41. At this time, the adjusting rod 441 and the movable plate 43 rotate, so that the movable plate 43 can slide along the axial direction of the guide rod 42. The operation is simple. Since the threaded connection between the adjusting rod 441 and the sliding plate 41 is self-locking, the position of the movable plate 43 can be fixed without rotating the adjusting rod 441.

[0043] In this embodiment, a tension spring 8 is installed on the side of the two sliding grooves 13 where the two sliding blocks 14 are close to each other. The two ends of the tension spring 8 are respectively connected to the sliding block 14 and the base 1. It is worth noting that when the sliding block 14 slides in the sliding groove 13 toward the side away from the connecting block 11, the tension spring 8 is deformed by the force. By setting the tension spring 8, when the gate valve is assembled, the valve seat 3 is placed on the placement plate 2 and a downward pressure is applied to the valve seat 3 so that the four limit plates 4 are in conflict with the valve seat 3, the tension spring 8 is in a natural state. After the gate valve is assembled, the fixing of the connecting shell 12 and the connecting block 11 by the fixing part 6 is cancelled. At this time, the sliding block 14 can be slid in the sliding groove 13 toward the connecting block 11 by the tension spring 8, so that the four limit plates 4 are away from the valve seat 3, which is convenient for cutting the valve seat 3.
