Abstract
The utility model discloses a hob locating device in gear hob centering processing comprising a locating rod, with its one end having a tapered locating piece on top of the locating rod and a bed frame with magnet, within the locating rod is located an adjustable probe with a tapered top, the locating rod is adjustably connected with the bed frame by thread. The tapered locating piece is tightly fastened against the wedge-shaped locating slot for automatic centering with said structure. The top of adjustably probe is changed into a taper shape not only improving locating precision, but also enabling it free from the limit of gear hob angle. The utility model can also adjust location of the helical gear hob device.
Description
Technical field
The utility model relates to gear hobbing processing hobboing cutter centering positioner.
Background technology
At Gear Processing various in style, the manufacturing process that the factory owner wants is to adopt the hob cutting device to carry out milling on gear embryo spare, and gear embryo spare is fixed by the top and collet of gear-hobbing machine.Before processing, at first to determine the center of hobboing cutter,, hobboing cutter gear hobbing tooth root center and gear embryo spare processing tooth tooth top place to be processed be coincide just can produce satisfactory gear by regulating the hobboing cutter position.At present commonly used in the factory is as shown in Figure 1 hobboing cutter positioner, the pedestal 92 that promptly fixedly has magnet 921 and locating piece 91 at square backstay 93 1 ends, be provided with tuning probe 94 in the backstay 93, tuning probe 94 front ends are for there being certain thickness triangle.Realize the Working position location of hobboing cutter by the gear hobbing tooth root center of alignment tuning probe front end and hobboing cutter, this structure, its locating piece 91 is fixing not movable with pedestal, in the time of when the hob cutting device is adsorbed on the predefined locating slot 5 of gear-hobbing machine by magnet 21 in, (locating slot 5 is seen structure shown in Figure 3), because locating piece 91 and 5 of locating slots have certain interval, loosening easily, depart from the center, thereby influence positioning accuracy, and tuning probe 94 front ends are certain thickness triangle, for helical gear hob cutting processing unit (plant), owing to tuning probe 94 can not rotate, and the gear hobbing of hobboing cutter is a helical teeth, make tuning probe 94 can not realize accurately aliging, thereby can not realize the location adjusting this situation with the tooth root place of hobboing cutter gear hobbing.
Summary of the invention
The purpose of this utility model is to provide a kind of location accurate, is difficult for becoming flexible, and also can realize locating the gear hobbing processing hobboing cutter centering positioner of adjusting to the hobboing cutter position of helical gear hob cutting processing unit (plant).
To achieve these goals, the technical solution adopted in the utility model is: gear hobbing processing hobboing cutter centering positioner, comprise backstay, the pedestal that backstay one end is provided with locating piece and has magnet, be provided with tuning probe in the backstay, it is characterized in that: to be that screw thread is active with pedestal be connected described backstay, and described tuning probe top is conical, described locating piece is located at the backstay upper end, and this locating piece is a pyramid type.
The utility model is a pyramid type owing to having adopted technique scheme, locating piece, can cooperate very closely with the locating slot of wedge shape, is difficult for becoming flexible, and realizes the automatic centering heart.And because taper shape is made at the tuning probe top into, the precision when not only making the location is improved, and makes tuning probe not be subjected to the influence of gear hobbing hobboing cutter angle simultaneously, also can realize the location adjusting to helical gear hob cutting processing unit (plant).
Description of drawings
Below in conjunction with accompanying drawing the utility model is illustrated in further detail
Fig. 1 is the structural representation of conventional gears rolling cut processing with hobboing cutter centering positioner.
Fig. 2 is the structural representation of the utility model gear hobbing processing with hobboing cutter centering positioner.
Fig. 3 is the utility model gear hobbing processing hobboing cutter centering positioner and gear-hobbing machine fit structure schematic diagram.
Fig. 4 is the stereogram of the utility model gear hobbing processing with hobboing cutter centering positioner.
The specific embodiment
Shown in Fig. 2,3,4, a kind of gear hobbing processing hobboing cutter centering positioner of the utility model, comprise backstay 3, the pedestal 2 that backstay 3 one ends are provided with locating piece 1 and have magnet 21, be provided with tuning probe 4 in the backstay 3, described backstay 3 and pedestal 2 are by 31 active connections of screw thread, and described tuning probe 4 tops are conical, described locating piece 1 is located at backstay 3 upper ends, and this locating piece 1 is a pyramid type.
When adopting this device to locate the hob cutting position, locating piece 1 is inserted in the locating slot 5 of the default wedge shape of gear-hobbing machine, by magnet 21 pedestal 2 is adsorbed on the gear-hobbing machine guide rail.Rotate backstay 3 this moment and cooperate closely, shift phenomenon can not occur until the locating slot 5 of conical locating piece 1 and wedge shape.Stir adjusting nut 41 on the backstay 3 then and tuning probe 4 is moved down approach to hobboing cutter surface point of a knife or cutter groove position, the fixed cap of adjusting on the back rotation adjusting nut 41 411 makes adjusting nut 41 fixing.Regulate the control nut 61 on the hobboing cutter device 6 at last, make the tooth root place of hobboing cutter 62 and tuning probe 4 align.As long as the center of the processing tooth on the hobboing cutter 62 and tuning probe 4 alignment, hobboing cutter 62 and gear embryo spare coincide in the time of just can guaranteeing work, and the gear of producing meets the requirements.After treating that the hobboing cutter position is adjusted, unclamp fixed cap 411, stir adjusting nut 41 and make tuning probe 4 be recovered in the backstay 3, take off gear hobbing processing and get final product with hobboing cutter centering positioner.
And has the helical gear hob cutting processing unit (plant) at certain angle of inclination for gear hobbing, because the top of tuning probe 4 is conical, be not subjected to the influence at hobboing cutter angle of inclination, can realize by the mode that tooth root aligns with probe tip adjusting, still can very accurately process the accurate adjustment location of rolling cut position hobboing cutter device 6.
