Description
Technical field
The utility model relates to the knife rest that uses on a kind of numerically controlled lathe and the engine lathe, but a kind of specifically novel calibration multistation quick-change tool holder.
Background technology
The knife rest that uses on the traditional lathe mostly is square knife rest greatly, and the knife rest of this structure is merely able to install four cutters, just needs the frequent cutter of changing can satisfy production requirement when processing stations surpasses four kinds; When the part of processing was widely different, the slide carriage on the lathe must be done suitable moving and adjusting; The center cutter Height Adjustment is very difficult, when can not find suitable pad, have only by changing thrust and force to make center cutter to produce fine difference, and this will certainly cause the variation of tool geometry angle, cause cutter flexural deformation even fracture, thereby influence cutting ability and effect; Must readjust the center cutter height when changing cutter, desirable cutting-tool angle will just can be decided through trial cut repeatedly; Knife rest be connected with lathe be pin instead by the location, have very big gap between the two, cause the cutter reseting precision poor, it is unreliable locate, cutting vibration is huge, quality and efficient that influence is processed.
Summary of the invention
The purpose of this utility model is exactly the defective at existing knife rest, but a kind of novel calibration multistation quick-change tool holder is provided, and it can provide 40 tool change positions to realize rapid changing knife, can realize the outer tool setting of machine if use tool setting device, and its positioning accuracy is constant.
The technical solution of the utility model is achieved in that it comprises cutter hub (2) and cutter holder (4), it is characterized in that: cutter hub (2) is a cuboid, the center has axis hole (10), be provided with guide rail (11) all around, be fixed with axle (1) by last drive sleeve (9) and underdrive cover (8) in the axis hole (10), fluted disc (3) is equipped with in cutter hub (2) bottom, fluted disc (3) is meshed with the plane awl tooth of cutter hub (2) bottom by plane awl tooth (12), by guide rail (11) activity cutter holder (4) is housed around the cutter hub (2).
The utility model technical scheme preferably is: described cutter hub (2) has dovetail guide (11) all around, and dovetail guide (13) should be arranged on the cutter holder (4) mutually, and dovetail guide (11) is meshed with dovetail guide (13); Disk spring is equipped with in the bottom of described cutter hub (2); Described cutter hub has eccentric pivot hole on (2), cutter hub (2) waist has axis hole (13), eccentric shaft (6) is housed in the eccentric pivot hole, axis hole (13) level is equipped with pull rod shaft (5), eccentric shaft (6) is fixed in the axis hole (14) on the pull rod shaft (5), have draw-in groove (15) on the pull rod shaft (5), the end face of draw-in groove (15) is close to the dovetail guide of cutter holder (4).
The better technical scheme of the utility model is: 40 plane awl teeth are arranged at the bottom of described cutter hub (2), and the angle of adjacent two teeth is 9 °; Described cutter holder (4) is gone up and is fixed with adjustment seat (7) by trip bolt and pin, and bolt (16) is housed on the adjustment seat (7), and bolt (16) lower end withstands on the top of cutter hub (2) and fixes its position by nut.
Dovetail guide on the utility model cutter holder (4) and cutter hub (2) dovetail guide form and are slidingly matched, thereby realize that cutter holder (4) can vertically move up and down, and reach to guarantee reseting precision and regulate the high purpose of center cutter; Pull rod shaft (5) cooperates realization cutter hub (2) and cutter holder (4) to clamp and unclamps with eccentric shaft (6); By inclined wedge-shaped cam structure between underdrive cover (8) on the axle (1) that is installed in cutter hub (2) center and the last drive sleeve (9), realize lifting fast of cutter hub (2), transposition falls locking; 40 even distribution plane awl teeth in cutter hub (2) bottom and fluted disc (3) engagement, adjacent two bottom angles are 9 °, thereby realize the knife rest calibration.Be fixed with adjustment seat (7) on the described cutter holder (4), adjustment seat is equipped with bolt on (7), realizes the high adjustment of center cutter by regulating bolt length and hold-down nut.
But this calibration multistation quick-change tool holder that the utility model provides is compared with common square tool post, and is rational in infrastructure, and accurate positioning is easy to adjust, the outer tool setting of machine.Owing to take the dovetail guide engagement, the contact site lengthening guarantees that straight line moves reliability to cutter hub (2) with cutter holder (4), thereby ensures reset precisely (repetitive positioning accuracy 0.005mm); Indexing accuracy of the present utility model is guaranteed by plane awl tooth, adjacent two bottom angles of awl tooth, this plane are 9 °, make knife rest can be in 360 ° of scopes with the multiple location of 9 ° and 9 °, its structure can guarantee the running accuracy of platen and knife rest, and do not need to use very expensive control appliance and sensor to monitor and angle correction, conserve space and expense, this point is very important to the NC Digit Control Machine Tool, in addition, because per tooth has considerable surface to participate in engagement, so surface pressing is very low, it is less to wear and tear, and has overcome plain cutter holder and has easily produced the cutting vibration phenomenon; The utility model is to realize by the underdrive cover (8) that cutter hub (2) connects, its principle is to rotate last drive sleeve (9) to pass through the Wedge type cam structure between drive sleeve up and down, under the tension force effect of disk spring, cutter hub (3) is lifted, after finishing indexing, fall locking by the voussoir gradient again.The adjusting that center cutter is high only need be adjusted bolt and get final product, do not need to use pad, can realize the outer tool setting of machine by tool setting device, this point is important too to the NC Digit Control Machine Tool, take eccentric stiffener, it is reliable rapidly to unclamp the clamping cutter holder, and exchanging knives process can be finished in the several seconds, when changing cutter holder or cutter, reseting precision is up to 0.005mm.
