Description

Technical Field

[0001] This utility model belongs to the field of valve processing technology, and in particular relates to a positioning device for drilling valve bodies. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, and regulating valves, etc. Valves used in fluid control systems have various structures and functions, ranging from the simplest shut-off valves to the various valves used in extremely complex automatic control systems; their types and specifications are quite numerous. The valve body is the main component of the valve, and the other parts of the valve are installed on the valve body, thus forming the valve.

[0003] During valve body processing, drilling is often required. To prevent the valve body from shaking during drilling, which could cause the borehole to tilt or change in diameter, a clamp is usually used to hold and fix the valve body. Due to the internal structure of the valve body, it is necessary to drill holes in the side of the valve body at an angle. During the drilling of angled holes, a clamp capable of fixing the angled surface is required.

[0004] Currently, there are some solid support platforms in the shape of triangles or trapezoids that can fix the valve body on an inclined plane. However, these types of fixtures can only provide a fixed tilt angle. If an angle-adjustable structure is chosen as the support, the fixture structure used to support the valve body may wobble due to the large self-weight of the valve body and the torque generated during the machining process, resulting in insufficient stability and affecting the final machining result. Therefore, it is urgent to design a positioning device for valve body drilling to solve the above problems. Utility Model Content

[0035] Working principle:

[0036] By setting the clamping component 9, the valve body can be clamped and positioned, which facilitates subsequent drilling operations.

[0037] The tilt angle of the flip plate 6 can be adjusted by setting the adjustment drive component 7. The operation is simple. Just loosen the locking nut on the adjusting screw 7-5, and then push the adjusting screw 7-5 upward or pull it downward to achieve the purpose of pushing the flip plate 6 upward or pulling it downward. During the above adjustment process, the tilt angle of the flip plate 6 can be determined by observing the scale on the angle plate 10 indicated by the index installed on the flip plate 6. After the flip plate 6 is tilted to the required angle, tighten the locking nut on the adjusting screw 7-5 to lock the position of the flip plate 6, so that the valve body clamped on the clamping component 9 can perform drilling operations in the tilt direction.

[0038] By setting the top plate adjustment component 5, the lateral position of the drilling top plate 3 can be adjusted, thereby adjusting the lateral position of the drill sleeve 4, so that the center of the drill sleeve 4 can be aligned with the drilling point on the valve body, thus improving the applicability of the device.

[0039] The support assembly 8 provides support for the bottom surface of the flip plate 6. The wedge drive mechanism drives the support wedge 8-7 and support plate 8-5 to move up and down, and the screw adjustment mechanism adjusts the lateral movement of the support wedge 8-7 and support plate 8-5. This ensures that the support wedge 8-7 and support plate 8-5 in the support assembly 8 can provide stable support for the flip plate 6 after the tilt angle of the flip plate 6 changes, preventing the flip plate 6 from shaking during processing, improving the stability of the positioning device, and improving the final processing result.
