Description
Technical Field
[0001] This utility model applies to the field of assembly tooling technology, and in particular relates to an assembly tooling for a desuperheater and pressure reducer cylinder. Background Technology
[0002] Currently, desuperheating and pressure reducing devices are key safety devices in the industrial field. Through components such as pressure reducing valves, throttling orifice plates, and atomizing nozzles, they can precisely regulate high-temperature and high-pressure steam into low-pressure and low-temperature steam that meets process requirements. They are widely used in industries such as power, chemical, and food. Their core advantages lie in high-precision PID control and modular design, which can flexibly cope with different working conditions. When processing the pressure reducing device cylinder, in order to improve its processing stability, it is often equipped with corresponding tooling for auxiliary installation.
[0003] However, currently, when using tooling to assist in the machining and fixing of pressure regulator cylinders, the limitations of the tooling structure mean that the tooling can only be adjusted from one side when the cylinder is placed on the tooling surface. This results in the pressure regulator's outer wall being obstructed, and the pressure regulator not being able to be centered on the tooling surface. Consequently, when machining the outer wall of the cylinder, the machining tools need to be adjusted in real time according to the cylinder's position, affecting the machining efficiency of the outer wall. Therefore, we propose a pressure regulator cylinder assembly tooling. Utility Model Content
[0004] The main purpose of this utility model is to provide a tooling for assembling a desuperheater and pressure reducer cylinder, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A desuperheater cylinder assembly tooling includes a mounting base, with mounting holes vertically opened at the four corners of the side of the mounting base, a fixing pipe vertically fixedly installed at the top center of the mounting base, and four sets of abutment baffles vertically slidably installed on the top surface of the mounting base, with the abutment baffles located outside the fixing pipe. The fixed tube is equipped with a drive mechanism inside, and a rear conversion mechanism is provided between the outside of the fixed tube and the abutment baffle. The rotation mechanism and the drive mechanism are connected in a transmission manner. A limiting mechanism is provided on the outer side of the top end of the fixed tube, and the limiting mechanism and the driving mechanism are connected in a transmission manner.
[0006] As an optional solution to the technical solution of this application, the driving mechanism includes a bidirectional lead screw. The bidirectional lead screw is vertically rotatably mounted on the middle of the fixed tube via a bearing. Lifting sleeves are movably sleeved at both ends of the outer side of the bidirectional lead screw, and the lifting sleeves are movably disposed inside the fixed tube. A rotating rod is fixedly installed at the top of the bidirectional lead screw.
[0007] As an optional solution to the technical solution of this application, a fixing block is fixedly installed on the outer wall of each lifting sleeve, and four sets of limiting slide grooves are vertically and equidistantly opened on the outer side of the fixing tube, and the fixing block is slidably installed inside the limiting slide groove.
[0008] As an optional solution to the technical solution of this application, the conversion mechanism includes a connecting rod, and four sets of sliding plates are equidistantly slidably installed at both ends of the outer side of the fixed tube, and the outer side wall of the sliding plate at the top side of the fixed block is fixedly connected to each other. The outer side wall of the sliding plate and the abutment baffle are both provided with connecting blocks, and the connecting rod is hinged between the side ends of each two sets of connecting blocks through a rotating shaft.
[0009] As an optional solution to the technical solution of this application, the limiting mechanism includes a clamping bolt, a hollow tube is vertically fixed on the outer side of the top of the fixed tube, and a rotating rod extends through the inside of the hollow tube. A rotating frame is rotatably sleeved on the outer side of the hollow tube, and a clamping bolt is threaded through the bottom of the side of the rotating frame. A limiting slot is opened at the bottom of the outer side of the hollow tube, and the side end of the clamping bolt is movably fitted into the inside of the limiting slot.
[0010] As an optional solution to the technical solution of this application, each of the abutting baffles is fixedly installed with a sliding block at its bottom, and the top of the mounting base is provided with four sets of guide grooves at equal intervals, and the sliding block is slidably installed inside the guide groove.
[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. A desuperheater and pressure reducer cylinder assembly fixture according to this application, wherein a rotatable bidirectional lead screw is provided inside the fixed tube, and lifting sleeves are provided on both sides of the bidirectional lead screw. When the bidirectional lead screw is driven to rotate, under the guidance of the limiting slide groove on the fixed block, the two sets of lifting sleeves can move vertically in opposite directions or relative to each other inside the fixed tube. Under the connecting transmission action of the fixed block, a corresponding driving force can be provided to the sliding plate, so that the two sets of sliding plates located on the outer wall of the fixed tube move vertically in opposite directions or relative to each other simultaneously. Under the connecting and converting action of the connecting rod, the two ends of the connecting rod can be hinged in the rotation of the shaft. The connecting rod converts the vertical movement force of the sliding plate into a horizontal pushing force on the abutting baffle, so that the abutting baffle can move horizontally towards or relative to each other on the outer wall of the fixed tube. Adjusting the distance between the abutting baffles ensures that the outer walls of multiple sets of abutting baffles are fully in contact with the inner wall of the pressure reducer cylinder to be processed, and performs centering and limiting treatment on them. This ensures the stability of the pressure reducer body during processing, while preventing arbitrary lateral movement of the pressure reducer cylinder when it is fixed, which would affect the subsequent processing efficiency of its outer wall.

A desuperheating and pressure reducing device cylinder assembly tooling according to the technical solution of this application, by setting a hollow tube at the top of the fixed tube and rotating a frame rotatably sleeved on the outside of the hollow tube, and connecting the bidirectional screw and the rotating frame in conjunction with the rotating rod, so that the rotating frame can be turned to drive the bidirectional screw to rotate accordingly, which facilitates the position adjustment of the abutment baffle and the tightening bolts can be turned to fix the position of the rotating frame.

Detailed Implementation
[0015] like Figure 1-4 As shown, this utility model provides a technical solution: a de-icing and pressure reducing device cylinder assembly tooling, with mounting holes 11 vertically opened at the four corners of the side of the mounting base 1, a fixing pipe 12 vertically fixedly installed at the top center of the mounting base 1, and four sets of abutment baffles 13 vertically slidably installed on the top surface of the mounting base 1, with the abutment baffles 13 located outside the fixing pipe 12.
[0016] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), the limiting mechanism includes a clamping bolt 32. A hollow tube 3 is vertically fixed on the outer side of the top of the fixed tube 12, and a rotating rod 27 extends through the inside of the hollow tube 3. A rotating frame 31 is rotatably sleeved on the outside of the hollow tube 3. A clamping bolt 32 is threaded through the bottom of the side of the rotating frame 31. A limiting slot 33 is opened at the bottom of the outer side of the hollow tube 3, and the side end of the clamping bolt 32 is movably fitted into the inside of the limiting slot 33.
[0017] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), the driving mechanism includes a bidirectional lead screw 2. The bidirectional lead screw 2 is vertically rotatably mounted inside the middle of the fixed tube 12 via a bearing. Lifting sleeves 21 are movably sleeved at both ends of the outer side of the bidirectional lead screw 2, and the lifting sleeves 21 are movably disposed inside the fixed tube 12. A rotating rod 27 is fixedly mounted at the top of the bidirectional lead screw 2, and the rotating rod 27 extends from the inside of the top of the fixed tube 12 to its outer side via a bearing. A fixing block 22 is fixedly mounted on the outer wall of each lifting sleeve 21. Four sets of limiting slide grooves 26 are vertically and equidistantly opened on the outer side of the fixed tube 12, and the fixing blocks 22 are slidably mounted inside the limiting slide grooves 26.
[0018] In this technical solution (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), the conversion mechanism includes a connecting rod 25. Four sets of sliding plates 23 are equidistantly slidably installed at both ends of the outer side of the fixed tube 12. The outer side walls of the sliding plates 23 at the top side of the fixed block 22 are fixedly connected. The outer side walls of the sliding plates 23 and the abutting baffle 13 are provided with connecting blocks 24. The connecting blocks 24 are fixedly installed on the outer wall of the sliding plates 23. The side end of the abutting baffle 13 is connected to the connecting blocks 24 by bolts, so that the abutting baffle 13 can be disassembled and replaced from the outside of the connecting blocks 24. The connecting rod 25 is hinged between the side ends of every two sets of connecting blocks 24 through a rotating shaft.
[0019] In some technical solutions (through Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown), each abutment baffle 13 has a sliding block 41 fixedly installed at its bottom. The top of the mounting base 1 has four sets of guide grooves 4 equidistantly opened, and the sliding block 41 is slidably installed inside the guide groove 4.
[0020] During operation, when processing the cylinder structure of the desuperheater and pressure reducer, firstly, a stop baffle 13 that matches the curvature of the inner wall of the cylinder is selected. Then, the stop baffle 13 and connecting block 24 are assembled using bolts. Next, the stop bolt 32 is tightened to move it out of the limiting slot 33. The pressure reducer cylinder to be processed is then vertically fitted onto the outer wall of the fixed tube 12, so that the bottom end of the pressure reducer is in contact with the surface of the mounting base 1. Then, the rotating frame 31 is tightened, causing it to rotate outside the hollow tube 3. Simultaneously, under the connecting transmission action of the rotating rod 27, the bidirectional lead screw 2 rotates synchronously inside the fixed tube 12. Combined with the guiding action of the limiting slide groove 26 on the connecting block 24, the two sets of lifting sleeves 21 fitted onto the outer ends of the bidirectional lead screw 2 can move vertically and synchronously inside the fixed tube 12, and then... Under the connecting transmission action, the sliding plate 23 can be provided with a corresponding driving force, so that the two sets of sliding plates 23 located on the outer wall of the fixed tube 12 move vertically relative to each other synchronously. Then, combined with the connecting conversion action of the connecting rod 25, the two ends of the connecting rod 25 can be hinged in the rotation of the rotating shaft. The connecting rod 25 converts the vertical movement force of the sliding plate 23 into a horizontal pushing force on the abutting baffle 13, so that the abutting baffle 13 can move horizontally relative to each other synchronously on the outer wall of the fixed tube 12. Adjust the distance between the abutting baffles 13 until the side of the abutting baffle 13 is attached to the inner wall of the pressure reducer cylinder, and then tighten the bolt 32 in the opposite direction so that its side end is attached to the inside of the limiting slot 33. Fix the position of the rotating frame 31 and the abutting baffle 13, thereby fixing the pressure reducer cylinder. Then, use other processing tools to process the outer wall surface of the pressure reducer cylinder.
