One end of a cutter installing base is matched into the installing hole in the chuck body in a sliding mode, the cutter installing base is provided with a radial hole and an axial cutter installing hole, a locking screw penetrates through the radial through hole of the chuck body to stretch into the radial hole of the cutter installing base, an outer sleeve and a spring are arranged on the chuck body in a sleeved mode, one end of the spring is limited through a circumferential flange formed by the end of the chuck body, the other end of the spring is limited through a step face on the inner wall face of the outer sleeve, the radial hole in the cutter installing base is composed of a straight hole section and a spherical hole section, the spherical hole section is directly communicated with the cutter installing hole, a steel ball is arranged inside the spherical hole section, the locking screw stretches into the radial hole of the cutter installing base to be in threaded connection with the straight hole section of the radial hole, and the steel ball is pressed into a spherical hole. According to the cutter chuck device, the assembling precision of a cutter can be improved.
Description
Technical field
The utility model relates to a kind of cutter chuck device.
Background technology
A kind of cutter chuck device is disclosed in prior art, comprise chuck body, chuck 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 chuck body, coat suit is on chuck body outer peripheral face, clamping screw is installed between described tool fitting and chuck body, between described overcoat and chuck body, be provided with back-moving spring, back-moving spring is sheathed on the outer peripheral face of chuck body, when changing cutter, make the position of chuck body and cutter all the time in same position, the end of described chuck body is provided with locking member, locking member is interspersed in chuck body and tool fitting.This device is the locking to cutter by clamping screw, has realized cutter positioning and can not produce mistake, has improved processing work efficiency.The clamping screw that relies on completely of this cutter locks the cutter being inserted on tool fitting, but cannot reach equal owing to being distributed in the amount of feeding of cutter screw around, therefore, cause cutter axially depart from tool fitting centre bore axially, in process, cutter is had a negative impact.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of energy cutter chuck device, and the utility model can improve the assembly precision of cutter.
The technical scheme solving the problems of the technologies described above is as follows:
Cutter chuck device, comprise chuck body, tool fitting, overcoat, lock-screw and spring, chuck 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 chuck body, tool fitting is provided with radial hole and axial Cutting tool installation manner hole, lock-screw extend in the radial hole of tool fitting through the radial direction through hole of chuck body, described overcoat is enclosed within on chuck body, described spring housing is on chuck body, the peripheral flange that one end of spring forms by chuck 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 comprised of straight hole section and spherical pore section, described spherical pore section is directly communicated with Cutting tool installation manner hole, in spherical pore section, be provided with steel ball, 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 contacting with steel ball of described lock-screw is concave spherical surface.
Adopted such scheme, after the bar portion of cutter is inserted 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, lock-screw is pressed on steel ball in spherical pore section, steel ball compresses the bar portion of cutter, because the degree of depth of spherical pore section is invariable, therefore, steel ball enters into the amount of feeding in Cutting tool installation manner hole and also fixes, like this, the steel ball amount of feeding that is positioned at cutter both sides or many sides all equates, thereby be clamped in the cutter between these steel balls bar portion axially, with being axially located along the same line of Cutting tool installation manner hole, therefore, cutter is positioned on tool fitting accurately.Described spring housing is on chuck body, the peripheral flange that one end of spring forms by chuck body end is spacing, the other end of spring is spacing by the platform limit face on outer casing inner wall face, when changing cutter, make the position of chuck body and cutter all the time in same position, to guarantee that assembly precision is not affected.
Accompanying drawing explanation
Fig. 1 is cutter chuck apparatus structure schematic diagram of the present utility model;
1 is chuck 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.
The specific embodiment
With reference to Fig. 1, a kind of cutter chuck device of the present utility model, comprises chuck body 1, tool fitting 2, overcoat 3, lock-screw 4 and spring 5.Chuck 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 chuck body 1, tool fitting 2 is provided with radial hole and axial Cutting tool installation manner hole, and lock-screw 4 extend in the radial hole of tool fitting 2 through the radial direction through hole of chuck body 1.Described overcoat 3 is enclosed within on chuck body 1, and described spring 5 is enclosed within on chuck body 1, and the peripheral flange 11 that one end of spring 5 forms by chuck body 1 end is spacing, and the other end of spring 5 is spacing by the platform limit face on overcoat 3 internal faces.Radial hole on described tool fitting 2 is comprised of straight hole section and spherical pore section, described spherical pore section is directly communicated with Cutting tool installation manner hole, in spherical pore section, be provided with steel ball 6, 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 contacting with steel ball of described locking screw 4 is concave spherical surface.
