Abstract
The invention relates to a tool chuck device. An axial mounting hole and a radial through hole are formed in a chuck body; one end of a tool mounting seat is in sliding fit in the mounting hole in the chuck body; a radial hole and an axial tool mounting hole are formed in the tool mounting seat; a locking screw penetrates through the radial through hole in the chuck body and extends into the radial hole of the tool mounting seat; an outer sleeve sleeves the chuck body; a spring sleeves the chuck body; one end of the spring is limited by a circumferential flange formed at the end part of the chuck body, and the other end of the spring is limited by a step limiting surface on the inner wall surface of the outer sleeve; the radial hole in the tool mounting seat consists of a straight hole section and a spherical hole section; the spherical hole section is directly communicated with the tool mounting hole; a steel ball is arranged in the spherical hole section; the locking screw extends into the radial hole of the tool mounting seat; after the locking screw is in threaded connection with the straight hole section of the radial hole, the steel ball is pressed in a spherical hole. According to the tool chuck device, the assembling precision of a tool can be improved.
Description
Technical field
The present invention relates to a kind of cutter chuck device.
Background technology
A kind of cutter chuck device is disclosed in prior art, comprise Gripper body, Gripper body is provided with cutter folder hole, described cutter chuck device also comprises overcoat and clamping screw, tool fitting is fixedly installed in the cutter folder hole of Gripper body, coat suit is on Gripper body outer peripheral face, clamping screw is installed between described tool fitting and Gripper body, back-moving spring is provided with between described overcoat and Gripper body, back-moving spring is sheathed on the outer peripheral face of Gripper body, the position of Gripper body and cutter is made to be in same position all the time when changing cutter, the end of described Gripper body is provided with stopper, stopper is interspersed in Gripper body and tool fitting.This device to the locking of cutter by clamping screw, is achieved cutter positioning and can not produce mistake, improve processing work efficiency.The clamping screw that relies on completely of this cutter locks the cutter be inserted on tool fitting, but because the amount of feeding being distributed in the screw around cutter cannot reach equal, therefore, cause the axis of cutter to depart from the axis of tool fitting centre bore, in process, cutter is had a negative impact.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of energy cutter chuck device, the present invention can improve the assembly precision of cutter.
The technical scheme solved the problems of the technologies described above is as follows:
Cutter chuck device, comprise Gripper body, tool fitting, overcoat, lock-screw and spring, Gripper body is provided with axial installing hole and radial direction through hole, one end of tool fitting is slidably fitted in the installing hole on Gripper body, tool fitting is provided with the Cutting tool installation manner hole of radial hole and axis, lock-screw extend in the radial hole of tool fitting through the radial direction through hole of Gripper body, described overcoat is enclosed within Gripper body, described spring housing is on Gripper body, the peripheral flange that one end of spring is formed by Gripper body end is spacing, the other end of spring is spacing by the platform limit face on outer casing inner wall face, radial hole on described tool fitting is made up of straight hole section and spherical pore section, described spherical pore section is directly communicated with Cutting tool installation manner hole, steel ball is provided with in spherical pore section, described lock-screw extend in the radial hole of tool fitting, after being threaded with the straight hole section of radial hole, steel ball is pressed in spherical pore.
The end face contacted with steel ball of described lock-screw is concave spherical surface.
Have employed such scheme, the bar portion of cutter is inserted into after in the Cutting tool installation manner hole on tool fitting, rotation lock screw makes it to the feeding of steel ball direction, along with lasting feeding, steel ball is pressed in spherical pore section by lock-screw, the bar portion of cutter then compresses by steel ball, the degree of depth due to spherical pore section is invariable, therefore, the amount of feeding that steel ball enters into Cutting tool installation manner hole is also fixing, like this, the steel ball amount of feeding being positioned at cutter both sides or many sides is all equal, thus be clamped in the axis in the bar portion of the cutter between these steel balls, be located along the same line with the axis in Cutting tool installation manner hole, therefore, cutter is positioned on tool fitting accurately.Described spring housing is on Gripper body, the peripheral flange that one end of spring is formed by Gripper body end is spacing, the other end of spring is spacing by the platform limit face on outer casing inner wall face, the position of Gripper body and cutter is made to be in same position all the time, to guarantee that assembly precision is not affected when changing cutter.
Accompanying drawing explanation
Fig. 1 is cutter chuck apparatus structure schematic diagram of the present invention;
1 is Gripper body, and 11 is peripheral flange, and 2 is tool fitting, and 3 is overcoat, and 4 is lock-screw, and 5 is spring, and 6 is steel ball.
Detailed description of the invention
With reference to Fig. 1, a kind of cutter chuck device of the present invention, comprises Gripper body 1, tool fitting 2, overcoat 3, lock-screw 4 and spring 5.Gripper body 1 is provided with axial installing hole and radial direction through hole, one end of tool fitting 2 is slidably fitted in the installing hole on Gripper body 1, tool fitting 2 is provided with the Cutting tool installation manner hole of radial hole and axis, and lock-screw 4 extend in the radial hole of tool fitting 2 through the radial direction through hole of Gripper body 1.Described overcoat 3 is enclosed within Gripper body 1, and described spring 5 is enclosed within Gripper body 1, and the peripheral flange 11 that one end of spring 5 is formed by Gripper body 1 end is spacing, and the other end of spring 5 is spacing by the platform limit face on overcoat 3 internal face.Radial hole on described tool fitting 2 is made up of straight hole section and spherical pore section, described spherical pore section is directly communicated with Cutting tool installation manner hole, steel ball 6 is provided with in spherical pore section, described lock-screw 4 extend in the radial hole of tool fitting, after being threaded with the straight hole section of radial hole, steel ball 6 is pressed in spherical pore.The end face contacted with steel ball of described locking screw 4 is concave spherical surface.
