Description

Technical Field

[0001] The utility model relates to the technical field of regulating valve processing, in particular to a regulating valve body processing fixture. Background Art

[0002] The control valve body processing fixture is a device specially designed to fix the control valve body during the processing. The control valve is a key component used to control the flow, pressure and flow direction of the fluid. It is widely used in the petroleum, chemical, water treatment and other industries. The processing accuracy of its valve body is very high, so the design and use of the processing fixture is particularly important.

[0003] After searching, a special clamp for cutting and grinding a regulating valve with announcement number CN217943012U belongs to the technical field of tooling and fixtures for casting processing. It includes a first positioning base, a second positioning base and a third positioning base arranged horizontally, and the middle parts of the first positioning base, the second positioning base and the third positioning base are respectively detachably installed with a first clamping part, a second clamping part and a third clamping part, and the first positioning base, the second positioning base and the third positioning base are all installed on the base through a bracket. The utility model has the following beneficial effects: the utility model adopts 3 limit and clamping points, so the overall positioning reliability of the clamp is high and the operation is also simple. Matching with the existing mechanical arm type casting riser grinding robot or grinding machine tool makes the grinding of the regulating valve body more efficient and quick, effectively improves the production efficiency, and has low use cost, which can significantly reduce the labor intensity of workers.

[0004] Based on the above patent, the first end of the regulating valve body is constrained by the cooperation of the first positioning base and the first clamping part, the second end of the regulating valve body is constrained by the cooperation of the second clamping part and the second positioning base, and the third end of the regulating valve body is constrained by the cooperation of the third clamping part and the third positioning base, thereby realizing reliable positioning of the regulating valve body as a whole. In order to prevent the regulating valve body with a cast riser from tipping over, the new model adopts three limiting and clamping points, so the overall positioning reliability of the clamp is high and the operation is simple. The special fixture for cutting and grinding the regulating valve can be directly installed on the grinding machine or a mechanical arm-type casting riser grinding robot can be installed on the base, and matched with the existing mechanical arm-type casting riser grinding robot or grinding machine, so that the grinding of the regulating valve body is more efficient and quick, effectively improving production efficiency, and the use cost is low, which can significantly reduce the labor intensity of workers. However, the three-point fixed clamping method used in this patent will cause uneven fixing force on the valve body, resulting in poor stability when fixing the valve body. If the clamp's clamping of the valve body is unstable, it will cause vibration or deviation during the processing process, resulting in reduced processing accuracy, and the inability to ensure the consistency of product size and shape, thereby affecting the performance of the product.

[0005] Therefore, in view of the problem that the existing clamps are not stable when clamping the valve body and dust splashes during processing, a regulating valve body processing clamp that solves the above problems is needed. Utility Model Content
