Description

[Technical field]

[0001] The utility model relates to a double V-shaped needle roller guide rail structure of a bullhead spark machine. [Background Technology]

[0002] Existing Bullhead Spark Machines Figure 5 As shown in the figure, the linear motion mechanism of the moving axis of the CNC machine tool is generally composed of a linear guide rail plus a ball screw drive. The linear guide rail and the slider are respectively fixed on two mechanical transmission components that move relative to each other, such as Figure 5 The longitudinal axis of the Bullhead spark machine shown in the figure is supported by only two points. When the longitudinal axis moves forward and backward, it will easily cause the casting to be deformed due to its own center of gravity exceeding the Bescher fulcrum, thus affecting the geometric accuracy of the machine tool. In addition, since the Bullhead spark machine is top-heavy and foot-light, the top surface of the small horizontal axis slide rail bears the superimposed weight of the two castings of the longitudinal axis and the vertical axis, the wire gauge slider has a large load, and the ball bearing is easy to wear.
