It needs to carry out gear hobbing process by the gear blank workpiece to annular, it is existing to process gear teeth on workpiece
Processing method is that workpiece is set on plug, and is fixed to workpiece axial direction side, then by gear-hobbing machine to workpiece
Be processed, gear-hobbing machine when being processed to workpiece be easy plug is caused to damage, need to entire plug replace, cost compared with
It is high.
Invention content
The purpose of this utility model, which is to provide one kind, need not replace plug, the lower gear-hobbing machine workpiece positioning of processing cost
Axis.
To achieve the above object, the utility model adopts the following technical solution：A kind of gear-hobbing machine workpiece locating shaft, including with
The mutually fixed plug of platen, the plug are made of two sections of one section of plug and plug, and the outer diameter that one section of the plug is big
In two sections of outer diameter of the plug, two sections of the plug is located at one section of front side of plug, and fixed seat is arranged on two sections of the plug,
The fixed seat has front and back through with to two sections of resignings of the plug, through slot, the fixed seat is mutually solid with platen
Fixed, the outer diameter that one section of the plug is more than the internal diameter for running through slot, and two sections of the plug is fixedly arranged at the front end with locating shaft, described fixed
Position axis is two mutually independent parts with plug, and the locating shaft is coaxially disposed with plug, and the locating shaft front end is formed
Have external thread structure and be combined with locking nut, workpiece is set on locating shaft, the locking nut and locating shaft coordinate so that
Workpiece is limited between fixed seat front end face and locking nut.
Since locating shaft and plug are two parts, can be taken if locating shaft even if locating shaft and plug are fixed together
Go out and plug can't be caused to damage.By being arranged workpiece on locating shaft, so that the gear hobbing process of workpiece will not make plug
At damage, only locating shaft can be caused to damage, the cost of locating shaft is much lower compared with plug cost, to reduce production cost.
Preferably, recessed to be formed with locating slot, the positioning shaft rear end and locating slot after two sections of front end faces of the plug
Cell wall is formed with mutually matched fixing structure, and the positioning shaft rear end close-fitting is in the locating slot, or positioning shaft rear end glue
Hydropexis is in the locating slot.
Preferably, two sections of front end faces of the plug are located at the rear side of the fixed seat front end face.
Preferably, the fixed base rear end peripheral outer wall extends to outer circumferential to be formed with fixed seat bottom plate, it is described
Fixed seat bottom plate is combined with fastener so that fixed seat is fixed with platen, and the outer diameter of the fixed seat is less than the outer of workpiece
Diameter.
The utility model has the advantages that plug need not be replaced, it is lower-cost to produce and process.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the utility model.
Specific implementation mode
The utility model is further described below according to the drawings and specific embodiments.
As shown in Figure 1, a kind of gear-hobbing machine workpiece locating shaft of the utility model, including it is mutually fixed with platen 1
Plug, plug are made of for two section 22 one section 21 of plug and plug, the outer diameter of two section 22 more than plug of the outer diameter that one section 21 of plug, core
Two section 22 of stick is located at one section of 21 front side of plug, is arranged with fixed seat 3 on two section 22 of plug, fixed seat 3 has front and back through with right
Two section of 22 resigning of plug runs through slot, and fixed seat 3 is fixed with 1 phase of platen, and the outer diameter that one section 21 of plug, which is more than, runs through slot
Internal diameter, plug is fixedly arranged at the front end with locating shaft 4 for two section 22, and locating shaft 4 is two mutually independent parts, locating shaft with plug
4 are coaxially disposed with plug, and 4 front end of locating shaft is formed with external thread structure and is combined with locking nut 5, and workpiece 6 is set in positioning
On axis 4, locking nut 5 and the cooperation of locating shaft 4 are so that workpiece 6 is limited between 3 front end face of fixed seat and locking nut 5.
Recessed to be formed with locating slot after two section of 22 front end face of plug, 4 rear end of locating shaft is formed with mutually with positioning groove groove wall
The fixing structure of cooperation, 4 rear end of the locating shaft are formed with cloudy seam allowance in a ring, and locating slot rear end circumferential direction cell wall extends internally
To be formed with positive seam allowance, 4 rear end close-fitting of locating shaft is in locating slot.Two section of 22 front end face of plug is located at 3 front end face of fixed seat
Rear side.3 rear end peripheral outer wall of fixed seat extends to outer circumferential to be formed with fixed seat bottom plate 31, and fixed seat bottom plate is combined with tightly
For firmware so that fixed seat 3 is fixed with platen 1, the outer diameter of fixed seat 3 is less than the outer diameter of workpiece 6.
Since locating shaft and plug are two parts, can be taken if locating shaft even if locating shaft and plug are fixed together
Go out and plug can't be caused to damage.By being arranged workpiece on locating shaft, so that the gear hobbing process of workpiece will not make plug
At damage, only locating shaft can be caused to damage, the cost of locating shaft is much lower compared with plug cost, to reduce production cost.
