Description

Technical Field

[0001] The utility model relates to the field of positioning devices, in particular to a valve body internal cutting positioning device. Background Art

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc.

[0003] Valves are control components in fluid delivery systems, with functions such as shutoff, regulation, flow diversion, backflow prevention, pressure stabilization, flow diversion or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shutoff valves to the various valves used in extremely complex automatic control systems.

[0004] The valve body is a major component in the valve; there are different mechanical manufacturing methods depending on the pressure level.

[0005] In the prior art, during the production of valves, it is often necessary to perform cutting processing on the inside of the valve body. During the cutting processing of the valve body, in order to avoid displacement of the valve body during processing, a positioning device is usually required to position and fix the valve body during processing. However, since the structure of the existing positioning device is relatively complex and the staff needs to continuously debug when positioning the valve body, the positioning speed of the valve body is slow, thereby reducing the processing efficiency of the valve body. At the same time, the current positioning device can only position the valve body in a single direction, which will lead to the risk of loosening of other parts of the valve body during processing, thereby reducing the positioning effect of the valve. Utility Model Content

[0006] The main purpose of the utility model is to provide a valve body internal cutting and positioning device, which can effectively solve the problems in the background technology.

After the valve body is placed in the positioning groove on the top surface of the workbench and the connection parts of the valve body on both sides with the pipeline are placed between the symmetrical positioning clamping plates, the knob is rotated to drive the connecting rod to rotate. The connecting rod will drive the second bevel gear to rotate through the second rotating rods at both ends. The second bevel gear will drive the first bevel gear to rotate under the meshing action. The first bevel gear will drive the bidirectional screw to rotate through the first rotating rod, so that the front and rear symmetrical positioning clamping plates pass through the screw holes opened on the front end wall of the bottom connecting block along the bidirectional screw. The screw is moved relatively until the connecting parts between the two sides of the valve body and the pipeline are clamped and fixed in the arc-shaped clamping openings on the opposite wall of the symmetrical positioning clamping plates, so that the valve body can be quickly clamped and fixed on the top surface of the workbench.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1 - Figure 4As shown, in this embodiment, in order to facilitate the rapid positioning and fixing of the valve body 1 when cutting the inside of the valve body 1 of the valve by the positioning mechanism 4, the specific use principle of the positioning mechanism 4 in conjunction with the valve body 1 is as follows:

[0023] When processing the valve body 1, the valve body 1 is placed in the positioning groove 6 opened in the center of the top surface of the workbench 5, and the parts where the two sides of the valve body 1 are connected to the pipeline are placed between the positioning clamping plates 15 that are symmetrical on the left and right sides of the top surface of the workbench 5. Then, the knob 23 installed on the outside of the center of the connecting rod 20 is rotated, and the knob 23 will drive the connecting rod 20 to rotate. The second rotating rods 21 installed on the left and right ends of the connecting rod 20 will rotate in the second rotating holes 11 opened on the side walls of the left-right symmetrical fixing plate 10 installed on the front end wall of the workbench 5, and the second rotating rod 21 will drive the second bevel gear 22 installed on the outer end wall to rotate. The second bevel gear 22 is meshed with the first bevel gear 14, so the second bevel gear 22 will drive the first bevel gear 14 to rotate under the action of meshing when it rotates. The first bevel gear 14 is installed on the end wall of the first rotating rod 13 at the front end of the bidirectional screw 12. Therefore, the first bevel gear 14 will drive the first rotating rod 13 installed at the front and rear ends of the bidirectional screw 12 to rotate in the first rotating holes 9 opened on the front and rear end walls of the recess 7 opened on the left and right sides of the top surface of the workbench 5, and the first rotating rod 13 will drive the bidirectional screw 12 to rotate in the recess 7. At this time, because the bottom surface of the front and rear symmetrical positioning clamping plate 15 is installed The connecting block 17 is threadedly connected with the bidirectional screw 12 through the screw hole 18 opened on the front end wall, so the connecting block 17 will move in the recess 7 along the bidirectional screw 12 through the screw hole 18, and the sliders 19 installed on both sides of the connecting block 17 will slide in the slide grooves 8 opened on the left and right side walls inside the recess 7. At the same time, the front and rear symmetrical positioning clamps 15 will respectively make relative movement operations on the top surface of the workbench 5 through the connecting block 17 installed at the bottom end, until the parts where the two sides of the valve body 1 are connected to the pipeline are clamped and fixed in the arc-shaped clamping openings 16 opened on the opposite surface walls of the front and rear symmetrical positioning clamps 15, and the knob 23 is not The valve body 1 can be quickly positioned and fixed on the top surface of the workbench 5 by simply and conveniently operating it. The valve body 1 can be quickly positioned and processed, and the two sides of the valve body 1 and the pipe connection parts can be clamped and fixed, which can effectively prevent the valve body 1 from loosening during processing, thereby not only improving the processing efficiency of the valve body 1, but also improving the positioning effect of the valve body 1. Finally, after the valve body 1 is positioned, the stopper 3 is inserted into the part where the valve body 1 is connected to the pipe on one side by the boring head 2, and then the boring head 2 is used to complete the cutting process on the inside of the valve body 1.
