Description

Technical Field

[0001] The utility model relates to the technical field of valve processing and fixing, in particular to a fixing frame for valve processing. Background Art

[0002] The valve is a key control component in the fluid conveying system. It can not only be used to open and close pipelines and control flow direction, but also to adjust and control the parameters of the conveying medium, such as temperature, pressure and flow rate. It has the functions of cut-off, regulation, diversion, backflow prevention, pressure stabilization, diversion or overflow pressure relief. Therefore, it is widely used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. In the process of valve processing, in order to facilitate the processing operation, it is often necessary to fix the valve, so a fixing frame is needed. However, the existing fixing frame structure usually adopts a structural method of clamping and fixing the outside of the valve, resulting in part of the surface of the valve being blocked by the clamping structure, affecting the surface grinding, painting and other processing operations of the valve. In view of this, the present application proposes a fixing frame for valve processing. Utility Model Content

[0003] The utility model aims to provide a fixing frame for valve processing, which has two valve fixing modes: internal expansion and fixing at both ends and clamping at both ends. In the internal expansion and fixing structure, the outer surface of the valve body is unobstructed, which is conducive to processing operations such as grinding and painting the outer surface of the valve body.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

This valve body fixing method adopts an internal expansion structure, and the outer surface of the valve body is unobstructed, which is conducive to the outer surface of the valve body. Polishing and painting and other processing operations are more practical. The expansion block 15 is curved in an arc shape, and a second rubber pad 16 is provided on the arc convex surface of the expansion block 15 to reduce wear on the valve.

[0024] As a preferred implementation scheme of this embodiment, the second driving mechanism 14 includes a through slot 17 opened on the fixed arm 4, and a one-way screw 18 is rotatably installed in the through slot 17. A sleeve block 20 is threadedly sleeved on the one-way screw 18, and the sleeve block 20 slides in contact with the inner wall of the through slot 17. The sleeve block 20 is hinged with a first expansion rod 21 on both sides of the sleeve block 20 facing a pair of expansion blocks 15, and the other end of the first expansion rod 21 is hinged to the middle position of the expansion block 15. A pair of second expansion rods 22 are hinged on the inner end wall of the through slot 17, and the other ends of the pair of second expansion rods 22 are respectively hinged to the middle of the pair of expansion blocks 15. The second driving mechanism 14 also includes a second motor 19, which is embedded in one end of the fixed arm 4 facing the vertical plate 2, and the output shaft of the second motor 19 is transmission connected to the one-way screw 18. By starting the second motor 19 to drive the one-way screw rod 18 to rotate, the sleeve block 20 is driven to slide in the through groove 17, forcing the pair of first expansion rods 21 and the pair of second expansion rods 22 to gather and rotate, so that the pair of expansion blocks 15 can be expanded away from the fixed arm 4 for expansion and fixation of the valve body.

[0025] As a preferred implementation scheme of this embodiment, the first driving mechanism 5 includes a bidirectional screw 7 rotatably installed on the top of the base plate 1, a pair of slides 6 threadedly sleeved on the bidirectional screw 7, and a first motor 8 installed at the end of the base plate 1 for driving the bidirectional screw 7 to rotate. A pair of vertical plates 2 are respectively fixed on a pair of slides 6.

[0026] In this embodiment, a slide groove 9 is opened on the upper surface of the substrate 1, and a slider 10 slidably engaged with the slide groove 9 is arranged at the bottom of the slide seat 6. The cross-sections of the slider 10 and the slide groove 9 are both set to a "⊥"-shaped structure. By utilizing the sliding engagement of the slide groove 9 and the slider 10, the translation of the slide seat 6 can be limited and guided.

[0027] In a further embodiment, a cross arm 3 is fixed to the top of the opposite sides of a pair of vertical plates 2, a fixed arm 4 is fixed on the cross arm 3, both ends of the cross arm 3 are equipped with electric push rods 11, a push plate 12 is fixed to the telescopic end of the electric push rod 11, and a first rubber pad 13 is provided on the surface of the push plate 12. By bringing a pair of expansion blocks 15 together close to the fixed arm 4, starting the electric push rod 11 to push the push plate 12 to the end of the fixed arm 4, and then driving the pair of vertical plates 2 to move closer to each other, the valve body can be clamped and fixed between the push plates 12 on the top of the pair of vertical plates 2, thereby achieving clamping and fixing of the valve body.

[0028] When in use, the valve is placed between the tops of a pair of vertical plates 2, the first motor 8 is started to drive the bidirectional screw rod 7 to move, and the pair of slide seats 6 drive the pair of vertical plates 2 to move toward each other, so that the fixed arm 4 and the corresponding expansion block 15 extend into the joints at both ends of the valve, and then the second motor 19 is started to drive the unidirectional screw rod 18 to rotate, drive the sleeve block 20 to slide in the through groove 17, and force the pair of first expansion rods 21 and the pair of second expansion rods 22 to gather and rotate, so as to expand the pair of expansion blocks 15 away from the fixed arm 4 until the pair of expansion blocks 15 and the corresponding expansion blocks 15 are connected. When the inner wall of the valve body joint is pressed tightly, the valve body can be supported and fixed. This valve body fixing method adopts an internal expansion structure, so the outer surface of the valve body is not blocked, which is more conducive to processing operations such as grinding and painting of the outer surface of the valve body. Furthermore, a pair of expansion blocks 15 are gathered close to the fixed arm 4, and the electric push rod 11 is started to push the push plate 12 to the end of the fixed arm 4. At this time, the pair of vertical plates 2 are driven to move closer to each other, and the valve body can be clamped and fixed between the push plates 12 on the top of the pair of vertical plates 2, thereby clamping and fixing the valve body.
