Abstract

PURPOSE:To make it possible to perform tilt angle adjustment work speedily with good accuracy by supporting an upper grindstone supporting quill by means of a frame, optionally adjusting the tilt by means of an adjustment mechanism to be fixed to the frame, and arranging a sensor for reading the tilt of the grindstone. CONSTITUTION:A quill 13 for supporting an upper grindstone 11 is supported via a swivel structure by means of a frame 12 and, while optionally adjusting the tilt of the upper grindstone 11 by means of an adjustment mechanism 34, is fixed to the frame 12 by means of a clamp mechanism 30. A grindstone tilt amount reading sensor 39 is rotatably arranged on an upper grindstone head. A center-corrected origin guide 41 is arranged on the frame 12. Accordingly, adjusting the tilt of the upper grindstone 11 becomes simple, greatly reducing the adjustment time and procedure. Also, since the tilt amount of the upper grindstone 11 can be detected and displayed by turning the sensor 39, it is possible to perform the tilt angle adjustment work very smoothly and with good accuracy.

As a means for inclining the axis of the upper whetstone (8) with respect to the axis of the lower whetstone (9), conventionally the main body frame (1) is divided into upper and lower parts, and the upper quill (2) of the upper whetstone (8) is ) by arbitrarily tilting the upper side of the frame that supports the lower whetstone (9) with respect to the lower side of the frame that supports the lower quill (3) of the lower whetstone (9), the axis of the upper whetstone (8) is aligned with the lower whetstone (9). However, it takes a lot of effort and time to tilt the upper side of the frame. Moreover, due to the tilting of the upper side of the frame, the upper whetstone (8
), it is necessary to divide the main body frame (1), and the strength of the main body frame (1) cannot be obtained. Therefore, if a moment is applied to the frame due to the grinding reaction force acting on the grinding wheel due to grinding resistance, the grinding surface of the grinding wheel will tilt during grinding, making it impossible to maintain close dimensional intersection and not allowing precision machining. .

In this invention, the quill supporting the upper whetstone is supported on the frame via a swivel structure, and the quill is freely rotated by an adjustment mechanism to arbitrarily adjust the inclination of the upper whetstone. Since it is fixed to the frame, it is easy to adjust the inclination of the upper whetstone, which greatly reduces the time and effort required for adjustment.Furthermore, there is no need to separate the frame as in the past, so it is easy to adjust the inclination of the upper whetstone. Since there is no need to divide the frame into two parts, the frame has strength and dimensional tolerance can be maintained during grinding, which has a great practical effect of being able to pass through precision machining. In addition, a sensor for reading the amount of inclination of the upper grinding wheel is rotatably installed on the upper grinding wheel head, and an origin guide centered on the frame is provided, so by rotating the sensor, it is possible to detect and display the amount of inclination of the upper grinding wheel. Therefore, the adjustment work of the inclination angle can be carried out extremely quickly and with high precision.

Furthermore, a piston is attached to the quill that supports the grinding wheel, a cylinder chamber is formed in the inner sleeve corresponding to the piston, and pressure is applied in the cylinder chamber to cause the threaded portion of the quill and the worm wheel supported by the inner sleeve to Since the backlash at the mating part is eliminated, the axial direction control of the grindstone can be performed accurately.
