Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of instrument valve group processing equipment, in particular to a kind of instrument valve group multi-valve group automatic assembly equipment. BACKGROUND

[0002] Instrument valve is a kind of pipeline accessories. It is used to change the section of passage and the direction of medium flow, and control the flow of conveying medium. The sealing performance of instrument valve refers to the ability of each sealing part of instrument valve to prevent medium leakage, which is the most important technical performance index of instrument valve. There are three sealing parts of instrument valve: the contact between the sealing surface of the opening and closing part and the valve seat; the joint of packing and valve stem and packing box; the connection between valve body and valve cover. The leakage of the former is called internal leakage, which is also commonly known as tightness, which will affect the ability of instrument valve to cut off medium. For cut-off valve, internal leakage is not allowed. The leakage of the latter two is called external leakage, i.e. the leakage of medium from inside the valve to outside the valve. External leakage will cause material loss, environmental pollution and even accidents in severe cases. For flammable, explosive, toxic or radioactive medium, external leakage is not allowed, so instrument valve must have reliable sealing performance.

[0003] The existing instrument valve group needs to be provided with multiple pipelines, and the direction of the pipelines on the instrument valve group is diversified, so that the equipment needs to be adjusted in advance during installation and setting. The general equipment adjustment needs to disassemble multiple parts, which is very inconvenient to adjust. SUMMARY

[0008] Preferably, the outer wall of the workpiece clamping block is provided with a linkage rod fixing hole matched with the linkage rod, and a material fixing groove is arranged below the workpiece clamping block.

[0009] Preferably, the outer part of the positioning seat is arc-shaped, and the shape of the outer part of the positioning seat is consistent with the shape of the inner part between the outer fixed frame and the inner fixed frame.

[0010] Preferably, the fixed frame connecting block is provided with at least 12 fixed frame connecting blocks, and the fixed frame connecting blocks are uniformly distributed between the outer fixed frame and the inner fixed frame, and the outer wall of the fixed frame connecting block is provided with a threaded column mounting hole matched with the fixed threaded column.

The fixed threaded column of the device can penetrate through the threaded column mounting hole, so that the positioning seat can be arranged at the position of the fixed frame connecting block, and the position of the positioning seat can be fixed. The workpiece clamping block plays a role in fixing the instrument valve group main body, and the instrument valve group is fixed around. The fixed frame connecting block can connect the outer fixed frame and the inner fixed frame together, so that a gap is formed between the outer fixed frame and the inner fixed frame. The position of the positioning seat can be fixed through the gap. At the same time, the outer part of the positioning seat is arc-shaped, which improves the clamping effect of the positioning seat between the outer fixed frame and the inner fixed frame, so that the positioning seat is not easy to slide.

[0019] Please refer to Figures 1-5This invention provides a technical solution: an automatic assembly device for multiple valve groups of an instrument valve group, comprising a fixed base 3, an inner fixing frame 16 at the upper end of the fixed base 3, and several fixing frame connecting blocks 15 on the outside of the inner fixing frame 16. A threaded hole is opened in the center of the inner fixing frame 16. The fixed base 3 is hollow inside, and an mounting base 24 is installed at the lower end of the fixed base 3. A fixing rod 4 is provided inside the fixed base 3, and a first cylinder 5 is installed on the fixing rod 4. A second fixing nut 25 is fitted onto one end of the first cylinder 5, which passes through a linkage plate 6. This fixed base 3 is fixed to an external device via the mounting base 24. Simultaneously, the fixing rod 4 of the fixed base 3 serves to fix the first cylinder 5, which can be pushed... The linkage plate 6 moves to control the movement of the linkage rod 12. A material fixing seat 17 is provided in the central threaded hole of the inner fixing frame 16, and a linkage rod mounting hole 19 is provided on the outer wall of the material fixing seat 17. A linkage rod 12 is inserted into the linkage rod mounting hole 19.

A linkage rod fixing hole 22 matching the linkage rod 12 is provided on the outer wall of the workpiece clamping block 11, and a material fixing groove 21 is provided below the workpiece clamping block 11. The linkage rod fixing hole 22 on the workpiece clamping block 11 serves to fix the linkage rod 12, allowing the linkage rod 12 to be fixed to the workpiece clamping block 11 with screws. Simultaneously, the material fixing groove 21 below the workpiece clamping block 11 can... To fix the edge and position of the workpiece, an annular outer fixing frame 1 is fixed to the outer ring of the fixing frame connecting block 15. A positioning seat 14 is engaged between the outer fixing frame 1 and the inner fixing frame 16. The upper end of the positioning seat 14 is provided with a cylinder fixing seat 9, and the lower end of the positioning seat 14 is provided with a fixing threaded post 2. The length of the fixing threaded post 2 is greater than the thickness of the fixing frame connecting block 15, and a first fixing nut 23 is sleeved on the outside of the fixing threaded post 2. The fixing threaded post 2 in this structure is relatively long, which fixes the lower end of the positioning seat 14.
