Abstract
The utility model discloses a clamp device, and belongs to the field of metal processing cutters. The traditional cutter clamping part has the defect of less clamping force. The clamp device comprises a clamp body, a fixed plug and a cutter, wherein the front end of the clamp body is provided with an axial installation hole; the fixed plug is in a cylindrical shape, the fixed plug is arranged on the installation hole in a matching way, and the fixed plug is provided with a cutter clamping hole; the cutter is fixed in the cutter clamping hole of the fixed plug; the diameter of the fixed plug is larger than the diameter of the installation hole; and the clamp installation hole is heated so as to be enlarged, then the fixed plug is arranged in the clamp installation hole, and after the clamp installation hole is cooled, the fixed plug is constricted in the clamp installation hole. According to the utility model, the fixed plug is constricted in the clamp installation hole, and the fixed plug is fixedly arranged on in the clamp installation hole and difficult to loose because the diameter of the fixed plug is larger than the diameter of the clamp installation hole, so that the effect of supplying larger clamping force to the cutter is realized.
Description
Technical field
The utility model belongs to the metal working tool field, relates to the knife holder assemblies that a kind of milling machine processing is used.
Background technology
Tradition milling machine milling cutter is by the collet chuck clamping with spring, then screw locking by locking nut, after long-term processing is used, the threaded engagement of locking nut and collet chuck produces the gap, nut can not be locked collet chuck fully, yet this structure is less to the clamping power that cutter produces, and causes cutter can not be completely fixed on collet chuck, has affected the stability of cutter work.
The utility model content
The purpose of this utility model is exactly will solve existing tool-holder gripping member to have the less defective of clamping power, provides a kind of clamping power grip device larger, simple in structure.
for this reason, the utility model is by the following technical solutions: a kind of grip device, comprise chuck body and cutter, the front end of body is provided with axial installing hole, it is characterized in that: described grip device also comprises fixed plug, fixed plug is cylindrical, the fixed plug cooperation is installed on installing hole, fixed plug arranges the cutter folder hole, cutter is fixed in the cutter folder hole of fixed plug, the diameter of fixed plug is greater than the aperture of installing hole, installing hole is enlarged the heating of fixture installing hole, then fixed plug is installed in installing hole, after hole to be installed is cooling, fixed plug is tightened in installing hole.
As to technique scheme replenish and perfect, the utility model also comprises following technical characterictic.
Described fixed plug front end is exposed to the chuck body outside.
The rear end of described chuck body is provided with axis hole, and axis hole communicates with installing hole, and its diameter is less than the diameter of installing hole.
Use the utility model can reach following beneficial effect: the utility model is by tightening fixed plug in the fixture installing hole, due to the diameter of the fixed plug diameter greater than installing hole, fixed plug is fixedly installed in and is not easy in installing hole to become flexible, and has realized and can reach the effect that larger clamping power is provided to cutter.
