Example Embodiment

[0017] The present invention will be further described below in conjunction with the accompanying drawings:

[0018] Depend on Figure 1 to Figure 5 As shown, a heavy-duty double-spindle integral ball valve cyclone lathe includes left-right symmetrical cyclone lathe bodies, and the workpiece is placed between the left and right cyclone lathe bodies and fixed on a square box block 1 . The cyclone lathe body includes a bed body 8 on which a ball screw 5 is connected, a nut is connected on the ball screw 5, and a cyclone milling head box 4 is fixed on the nut. One end of the ball screw 5 is connected to the reducer 3 through an elastic die coupling, and the input end of the reducer 3 is connected to an AC servo motor 2. The elastic die coupling has the characteristics of no backlash and high torsional rigidity. , which can not only eliminate the problem of different transmission caused by the coaxial and angular errors between the ball screw and the reducer, but also effectively...

Abstract

The invention discloses a heavy double-spindle integral ball valve whirlwind lathe, and mainly solves the problem that the precision is not easy to guarantee when a valve body and a valve shaft in anexisting ball valve are machined. The whirlwind lathe is characterized by comprising whirlwind lathe single bodies in bilateral symmetry; each whirlwind lathe single body comprises a lathe body (8); awhirlwind milling head box (4) is slidably connected to the lathe body (8); a whirlwind milling head (6) is connected to the front end of the whirlwind milling head box (4); a whirlwind tool disc (7)is fixed to the front end of the whirlwind milling head (6); and a whirlwind tool holder (9) is connected to the whirlwind tool disc. According to the heavy double-spindle integral ball valve whirlwind lathe, a ball valve subjected to rough machining is integrally installed and then subjected to finish machining together, so that the coaxiality of the valve body and the valve shaft is greatly improved, and the quality and performance of the ball valve are improved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a heavy-duty double-spindle integral ball valve cyclone lathe. Background technique [0002] With the continuous development of hydropower stations in my country in recent years, the products of hydraulic turbine ball valves have been widely used. The sealing part of the turbine ball valve now adopts a metal sealing structure, and it is required that no water leakage is allowed between the metal sealing surfaces. like figure 1 As shown in the figure, the outer circle of the valve shaft and the inner circle of the valve body shaft hole in the integral ball valve require high dimensional accuracy and coaxiality. The general processing method is to process them separately and then assemble them together. The coaxiality of the circle and the inner circle of the shaft hole of the valve body greatly affects the processing quality and performance of the ball valve. SUMMARY OF THE INVENTION ...
