Abstract
The invention provides a cutter clamping claw, and relates to a cutter clamping component for cutter change in a cutter magazine of a numerical control lathe. The diameter of a cutter is D, the distance from the action surface of a spring to the center of the cutter is 1/4D, the distance from the spring to a pin shaft is rounded to 3/5D, the distance from the pin shaft to the center of the cutter is 3/4D, the distance from an inlet end of the cutter clamping claw to the center of the cutter is 1/4D, and the angle of the inlet end of the cutter clamping claw is 11 to 13 degrees. When the cutter is buckled by the cutter clamping claw which is produced according to the sizes, the lateral force on a main shaft is about 25% of the spring force. When the cutter is disengaged from the cutter clamping claw, the lateral force is 35% of the spring force. The cutter clamping claw has the advantage that the design is suitable for BT, JT, CAT, HSK and other series of cutter clamping cutters with various specifications.
Description
Technical field
A kind of folder cutter pawl relates to the parts that press from both sides cutter when being used for tool changing in the numerical control machine tool changer.
Background technology
Along with the increase of tool weight, require the also necessary ability clamp-on tool that increases of folder cutter pawl chucking power, folder cutter pawl chucking power increases side force increase when causing the main shaft tool changing, strengthens main shaft deformation.
Summary of the invention
Purpose of the present invention enters the angle of head and moment during by control folder cutter dog clutch cutter will press from both sides cutter the time, and the side force to main shaft is reduced to an acceptable degree.
This folder cutter pawl is take tool diameter as D, and spring action face to center cutter is got 1/4D, and spring is got 3/5D to bearing pin apart from rounding, and bearing pin to center cutter is got 3/4D, and folder cutter pawl enters head to center cutter and gets 1/4D, and folder cutter pawl enters brilliance degree and gets 11-13 °.
Side force to main shaft during the folder cutter dog clutch cutter produced by this size is about 25% of spring force, and side force was 35% of spring force when cutter deviate to press from both sides the cutter pawl.The design is applicable to, BT, JT, CAT, the folder cutter pawl of each specification of the series such as HSK.
Description of drawings
Fig. 1 is the size relationship schematic diagram of single folder cutter pawl.
The specific embodiment
This folder cutter pawl is take tool diameter as D, and spring action face to center cutter is got 1/4D, and spring is got 3/5D to bearing pin apart from rounding, and bearing pin to center cutter is got 3/4D, and folder cutter pawl enters head to center cutter and gets 1/4D, and folder cutter pawl enters brilliance degree and gets 11-13 °.
