Description
Technical field
The utility model relates to a kind of metal cutting processing with novel external splines vertical milling cutter.
Background technology
The existing cutter that is used for the external splines cut all is to use professional lathe to accomplish, and process equipment limits to very much, and professional machine tool investment cost is big.
Summary of the invention
The technical problem that the utility model will solve provides a kind of novel external splines vertical milling cutter that can be used with plain-milling machine or CNC milling machine.
The technical scheme that realizes the utility model is:
A kind of novel external splines vertical milling cutter; Said cutter comprises handle of a knife; Be provided with cooling duct and blade banking pin in the handle of a knife, the handle of a knife lower surface is provided with three equally distributed blade installation slots, is provided with blade knife pading block, blade and blade fixed block in each blade installation slot; Blade is installed on the blade knife pading block and the inside groove of blade snaps in the described blade banking pin, and the blade fixed block is fixed on the blade.
The described cutting edge that is installed in three blades in the blade installation slot is equal with respect to the handle of a knife distance between center line, when said three blades rotate on the sustained height circumference.
Said cooling duct comprises main cooling duct and three secondary cooling ducts, and said secondary cooling duct one end is connected with main cooling duct one end respectively, and the said main cooling duct other end is connected with the machine tool chief axis water inlet.
Be respectively equipped with on said blade knife pading block and the blade fixed block screw thread counter sink is installed; Correspondence position then is provided with internal thread hole in the blade installation slot; Screw passes the installation screw thread counter sink and the internal thread hole that is arranged on blade installation slot on blade knife pading block and the blade fixed block respectively, and blade knife pading block and blade fixed block are separately fixed in the blade installation slot.
The blade installation site is provided with fixedly inner peg, can be convenient for changing blade at any time, and it is unified to guarantee to change behind the blade tool dimension precision again at every turn.Blade can arbitrarily switch according to processing spline model, reaches the purpose that a cutter is used more.The external splines slotting cutter is the same with common slotting cutter principle, through the rotation of cutter product is cut, and just the blade of blade must be complementary with the spline model; In processing during spline, product is fixed on rotation dividing head or four, through the cutter rotation the single tooth of external splines is carried out straight line processing; Rotate dividing head or the 4th angle then, accomplish next tooth again, by this step cycle to next tooth; Process up to accomplishing the corresponding number of teeth of spline, thereby accomplish processing spline.
The utility model is conceived basically: external splines all is a linear pattern; And each tooth of spline is all consistent, and just angle distribution is different, and milling machine also is the straight line process principle; The conversion of angle only needs rotatable dividing head just can reach its effect, so as long as have the cutter that is complementary just can accomplish processing.
The external splines vertical milling cutter that the utility model provides can satisfy its processing characteristics requirement, and low cost of manufacture, can cooperate plain-milling machine, Digit Control Machine Tool to use.

The specific embodiment
Below in conjunction with the embodiment of description of drawings the utility model, so that the utility model person of ordinary skill in the field embodiment of the present invention easily.
See also Fig. 1 to Fig. 4; Present embodiment external splines slotting cutter is made up of the handle of a knife 1 that is provided with cooling duct 7 and blade banking pin 6, three blade installation slots 8 being evenly distributed on handle of a knife 1 lower surface, all is fixed with blade knife pading block 3, blade 2 and blade fixed block 4 in each blade installation slot 8.Blade 2 is installed on the blade knife pading block 3 and the inside groove 21 of blade 2 snaps in the blade banking pin 6, and blade fixed block 4 is fixed on the blade 2.The cutting edge that is installed in three blades 2 in the blade installation slot 8 is equal with respect to handle of a knife 1 distance between center line, guarantees cutter in rotary course, and three blades 2 rotate on unified height circumference and identical Zhou Jing.Cooling duct 7 is made up of main cooling duct 71 and three secondary cooling ducts 72, is used for blade 2 and converted products and cools off.Secondary cooling duct 72 1 ends are connected with main cooling duct 71 1 ends respectively, and main cooling duct 71 other ends are connected with the machine tool chief axis water inlet, and cooling water is sprayed onto on blade 2 and the converted products by secondary cooling duct 72.Blade knife pading block 3 is provided with installs screw thread counter sink 31, corresponding with the internal thread hole that is arranged on blade installation slot 8 81, through screw 5 blade knife pading block 3 is fixed in the blade installation slot 8, and blade 2 plays a supportive role, and strengthens the intensity of blade 2.Blade fixed block 4 is provided with installs screw thread counter sink 41, corresponding with the internal thread hole that is arranged on blade installation slot 8 82, through screw 5 that blade knife pading block 4 is fixing with blade installation slot 8.Blade 2 is put into blade banking pin 6 cooperations of blade installation slot 8 and blade installation slot 8, blade banking pin 6 blade 2 play the role of positioning, and can prevent that blade 2 from moving up and down again.At last with the locking of blade fixed block 4 usefulness screws 5, blade fixed block 4 has been the effects of blade 2 of being locked.After blade 2 is installed on the handle of a knife 1, again cutter is mixed with the cutter handle of a knife 1 identical spring strut chuck lathe of packing into, it is fixed on the machine shaft, rotary main shaft, the railway line that takes the air line carries out external splines processing to its product.Fig. 5, Fig. 6, Fig. 7 are respectively the structural representations of blade, blade knife pading block, blade fixed block.
