Embodiment Construction

[0013] The technical solution of this patent will be further described in detail below in conjunction with specific embodiments.

[0014] see Figure 1-2 , a tool for processing two-piece ball valve stem holes, including a clamping plate 1, a bottom plate 3, a seam plate 4, a stud bolt 5, a compression plate 6 and a pre-tightening nut 7, the clamping plate 1 and the bottom plate 3 is fixedly connected at a 90° right angle. The seam plate 4 is fixed on the bottom plate through the stud bolt 5 and the early warning nut 7. There is a threaded hole in the middle of the bottom plate 3. One end of the stud bolt 5 is connected to the threaded hole. The seam plate 4 There is a through hole in the center, the through hole is set on the outside of the stud bolt 5 and fixed with the early warning nut 7, the compression plate 6 is fixed on the upper end of the stud bolt 5 through the pre-tightening nut 7, and the compression is adjusted according to the size of the clamping valve body. T...

Abstract

The invention discloses a tool for machining valve stem holes of two-pieces ball valves. The tool comprises a clamping plate, a bottom plate, a seam allowance plate, a double-end bolt, a compressing plate and pre-tightening nuts. The clamping plate and the bottom plate are fixedly connected with each other to form a 90-degree right angle, the seam allowance plate is fixed onto the bottom plate bythe aid of the double-end bolt and the corresponding pre-tightening nut, and the compressing plate is fixed to the upper end of the double-end bolt by the aid of the corresponding pre-tightening nut.Compared with the prior art, the tool has the advantages that the tool is simple in structure, facilities for machining the valve stem holes are virtually increased by the aid of structural forms of clamp and positioning devices and compressing devices under the condition that the precision of the valve stem holes is guaranteed against being affected, the problem of machining inconvenience of boring machines can be solved, accordingly, the machining efficiency can be improved, and the manufacturing cost can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of valve manufacturing, in particular to a tool for processing two-piece ball valve stem holes. Background technique [0002] At present, there is a common phenomenon that enterprises do not make full use of resources and waste resources more seriously. Cost plays an important role in the economic activities of the entire enterprise. The level of cost directly determines the economic benefits of the enterprise. Reducing costs can improve market competitiveness and win greater profit margins for the enterprise. With the rise of labor and materials, the manufacturing cost of enterprises also rises. Therefore, cost control is an important link in the development of enterprises. If enterprises want to gain a firm foothold in the huge market, they must adapt to the needs of the market economy and allow enterprises to reduce costs. Input, high output, and always take cost reduction as the core goal of the enterpr...
