Description
Technical field
The utility model belongs to metal cutting process technical field, and being specifically related to is a kind of improvement of digital control vertical milling cutter construction.
Background technology
At present, machining center vertical milling cutter adopts spring clip to overlap installation way mostly, clamping force is adopted to carry out transmitting torque between traditional numeric-control vertical milling cutter handle of a knife and chuck, in order to ensure the stability of milling cutter in process, often adopt larger clamping force, but in process, if overload will cause the wearing and tearing of cracking of cutter and workpiece; Even if but clamping force is large again, milling cutter uses and is in cantilever position for a long time, in Milling Processes, likely occurs that milling cutter stretches out gradually from cutter holder, comes off even completely, causes the damage of workpiece and milling head; Notification number disclosed in existing State Intellectual Property Office of the People's Republic of China is CN203791705U, the day for announcing is on August 27th, 2014, application number has been the patent disclosure of 201420204550.0 about a kind of technical scheme of elasticity digital control vertical milling cutter, but in technique scheme, when not having substantive solution to transship, milling cutter comes off, and still can cause the wearing and tearing of workpiece and milling cutter.
Utility model content
The utility model, for above-mentioned technical problem, provides a kind of at simple and reasonable, easy to operate, safe and reliable and a kind of elasticity digital control vertical milling cutter of long service life.
For achieving the above object, the utility model adopts following technical scheme, the utility model comprises cutter head, knife rest, hold down gag, locating hole, the tail end of cutter head is provided with the locating hole of two row eight row, hold down gag is by fastening block, spring, lock-screw forms, spring is located between fastening block and lock-screw, cutter head is locked on knife rest by the joint of fastening block and locating hole by hold down gag, cavity is left in one end that knife rest and cutter head are locked, the cavity wall of knife rest is provided with the through hole corresponding with two row eight row locating holes on cutter head, its structural feature is that each locating hole side of cutter head is equipped with the lead-over groove communicated, the top of the lead-over groove of colleague is provided with the anticreep groove all communicated with lead-over groove of going together.
Described anticreep groove, the shape of lead-over groove are all identical with locating hole, and the degree of depth of anticreep groove, lead-over groove all can be shallower than locating hole; Locating hole wants mild to the passage of lead-over groove.
Described locating hole is taper concave surface, and its tapering is 90 °.
The length of the cavity on described knife rest is greater than the length of the cutter head of locking, to reserve accommodation cavity when cutter head is return.
Described anticreep groove is endless groove.
The utility model is compared with existing elasticity digital control vertical milling cutter; structure is simple; easy accessibility; stable performance, safe and reliable, not only achieve overload protection Accident prevention in work way and occur; and can withdrawing when transshipping and occurring; realize being separated of workpiece and milling cutter, avoiding the damage of workpiece and milling cutter, extend the service life of milling cutter.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model;
Fig. 2 is entirety assembling schematic diagram of the present utility model;
Fig. 3 is the structural representation of cutter head of the present utility model;
Fig. 4 is the structural representation of hold down gag of the present utility model.
In figure: 1-cutter head; 2-knife rest; 3-hold down gag; 4-locating hole; 5-lead-over groove; 6-anticreep groove; 7-fastening block; 8-spring; 9-lock-screw; 10-holds cavity.
Detailed description of the invention
Do further structure below in conjunction with accompanying drawing to the utility model to describe:
As shown in Figure 1, the utility model comprises cutter head 1, knife rest 2, hold down gag 3, locating hole 4, the tail end of cutter head 1 is provided with the locating hole 4 of two row eight row, hold down gag 3 is by fastening block 7, spring 8, lock-screw 9 forms, spring 8 is located between fastening block 7 and lock-screw 9, cutter head 1 is locked on knife rest 2 by fastening block 7 and the joint of locating hole 4 by hold down gag 3, cavity is left in one end that knife rest 2 and cutter head 1 are locked, cavity wall is provided with the through hole corresponding with two row eight row locating holes on cutter head 1, each locating hole 4 of cutter head 1 is other is equipped with the lead-over groove 5 communicated, the top of the lead-over groove 5 of colleague is provided with the anticreep groove 6 all communicated with lead-over groove 5 of going together.
Described anticreep groove 6, the shape of lead-over groove 5 are all identical with locating hole 4, and the degree of depth of anticreep groove 6, lead-over groove 5 can all be shallower than locating hole 4;
Locating hole 4 wants mild to the passage of lead-over groove 5; So that when cutter head 1 transships, the fastening block 7 of hold down gag 3 slips into anticreep groove 6 by locating hole 4 by lead-over groove 5, along with the tail end of cutter head 1 is retracted in the accommodation cavity 10 of knife rest 2, thus realizes the object of withdrawing, avoids the loss of cutter head and workpiece.
Described locating hole 4 is taper concave surface, and its tapering is 90 °; If tapering is excessive, hold down gag easily skids off when withdrawing, if tapering is too small, the seal face of hold down gag is smaller, easily fractures in the course of the work.
The length of the cavity on described knife rest 2 is greater than the length of the cutter head of locking, to reserve the accommodation cavity 10 when cutter head is return.
During work, by regulating hold down gag 3 to regulate safe pretightning force, ensure when cutter transships; hold down gag can arrive anticreep groove 6 by lead-over groove 5 from locating hole 4, and now cutter head 1 also rises thereupon, departs from surface of the work; namely achieve the overload protection of cutter head, prevent again cutter head 1 from coming off.
