Description
Technical field
The utility model relates to a kind of processing unit (plant).
Background technology
Tradition milling machine milling cutter clamps by a collet chuck with spring, then by locking nut, screw locking, after long-term processing is used, the threaded engagement of locking nut and collet chuck produces gap, nut can not be locked collet chuck completely, yet the clamping power that this structure produces cutter is less, cause cutter can not be completely fixed on collet chuck, affected the stability of cutter work.And the clamping screw that relies on completely of milling cutter locks the milling cutter being inserted on tool fitting, but cannot reach equal owing to being distributed in the amount of feeding of milling cutter screw around, therefore, cause cutter axially depart from tool fitting centre bore axially, in process, milling cutter is had a negative impact.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of processing unit (plant), and the utility model can improve the assembly precision of cutter, reduces the adverse effect that cutter is subject in process.
The technical scheme solving the problems of the technologies described above is as follows:
A kind of processing unit (plant), comprise main shaft positioning device, main shaft positioning device is connected with outer support, outer support is connected with power transmission, power transmission is connected with blade clamping apparatus, blade clamping apparatus is connected with cutter, blade clamping apparatus comprises tool fitting, overcoat, lock-screw, tool fitting is provided with radial hole and axial Cutting tool installation manner hole, 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, overcoat is enclosed within on tool fitting, put outward and be provided with radial direction through hole, described lock-screw is through after the radial direction through hole of overcoat, after extending into and being threaded with the straight hole section of radial hole in the radial hole of tool fitting, steel ball is pressed in spherical pore.
Above the circumference of described tool fitting, be provided with spline.
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.When power transmission drives blade clamping apparatus to rotate, because the positioning precision of cutter self has improved, therefore, the turning effort power of cutter is in poised state, when being subject to cutting resistance, reduced the adverse effect to cutter, make the instrument efficiency of cutter there to be the life-span all to obtain raising.
Accompanying drawing explanation
Fig. 1 is a kind of processing unit (plant) structural representation of the present utility model;
1 is that main shaft positioning device 2 is outer support, and 3 is power transmission, and 4 is blade clamping apparatus, and 5 is cutter, and 41 is tool fitting, and 42 is overcoat, and 43 is lock-screw, and 44 is steel ball, and 45 is spline.
The specific embodiment
With reference to Fig. 1, a kind of processing unit (plant) of the present utility model, comprises main shaft positioning device 1, main shaft positioning device is connected with outer support 2, outer support 2 is connected with power transmission 3, and power transmission 3 is connected with blade clamping apparatus 4, and blade clamping apparatus 4 is connected with cutter 5.Blade clamping apparatus comprises tool fitting 41, overcoat 42, lock-screw 43.Above the circumference of tool fitting 41, be provided with spline 45, by spline, be convenient to be connected with power transmission 3.Tool fitting 41 is provided with radial hole and axial Cutting tool installation manner hole, and the radial hole on described tool fitting is comprised of straight hole section and spherical pore section, and described spherical pore section is directly communicated with Cutting tool installation manner hole, is provided with steel ball 44 in spherical pore section.Overcoat 42 is enclosed within on tool fitting 41, overcoat 42 is provided with radial direction through hole, described lock-screw 43 is through after the radial direction through hole of overcoat 42, after extending into and being threaded with the straight hole section of radial hole in the radial hole of tool fitting, steel ball 44 is pressed in spherical pore.The end face contacting with steel ball of lock-screw is concave spherical surface, and this shape not only mutually forms and coordinates with steel ball, and can also produce larger pressure to steel ball.
