Description

Technical Field

[0001] The present application relates to the technical field of valve production and manufacturing, and in particular to an automatic drilling machine for valve surfaces. Background Art

[0002] In terms of valve production and manufacturing, valves, as fluid control equipment, play an indispensable role in industrial production. There are many types of valves, such as gate valves, stop valves, check valves, etc., which are widely used in petroleum, chemical, electric power, metallurgy and other industries. The production and manufacturing process of valves is complicated, involving multiple links such as material selection, casting, machining, heat treatment, assembly, etc. The selection of materials needs to consider its corrosion resistance, wear resistance and strength. The casting process requires that the internal structure of the valve is dense and free of defects such as pores and shrinkage holes. Machining needs to ensure the accuracy and fit of each valve component. Heat treatment is used to improve the mechanical properties of the material. Finally, the assembly link ensures that the valve can work normally and stably.

[0003] In terms of drilling technology, drilling holes on the valve surface is one of the important links in the valve manufacturing process. Since the valve needs to be drilled around a circle, the traditional drilling method has some problems. Usually, after a single drilling is completed, manual operation is required to rotate the valve to the next drilling position before the next drilling is performed. This method is not only inefficient, but also prone to inaccurate drilling positions due to human errors, affecting the quality and performance of the valve, so it needs to be improved.

When one drilling operation is completed, the rotary motor 31 is started to drive the rotary disk 32 and the rotary column 33 to rotate, thereby driving the drilling table 34 and the valve placed thereon to perform circular motion. Since the center of the drilling table 34 and the drilling center of the drilling mechanism 2 are not located on the same axis, the valve will present an eccentric rotation state during the rotation process, so that the different The positions pass under the drill bit in turn until the valve rotates to the predetermined position, and the drilling mechanism 2 continues to work, and the drilling mechanism 2 performs the drilling operation again, and repeats this process until all the predetermined positions are drilled; the arrangement of the rotary motor 31, the rotary disk 32, the rotary column 33 and the drilling table 34 helps to realize automated drilling operations, simplifies the positioning and rotation steps of the valve during the drilling process, and compared with traditional manual rotation of the valve, can greatly reduce the operation time and manpower input, reduce the work intensity, improve the drilling efficiency and drilling accuracy, ensure that each predetermined drilling position on the valve surface can be accurately aligned with the drill bit, and reduce the possibility of human error.
