Abstract
The utility model provides a hole gerar grinding frock for gear in ladder for on the gear grinding machines, including dabber, clamp, packing ring, nut, its characterized in that gerar grinding frock structure: the plane center hole adds the clamp, pacifies the big footpath of hole gear nose end in the work piece ladder on dabber second, four major diameter round platforms under the dabber to install opening pad, conical surface washer, spherical washer on the hole gear path nose end face in proper order in the work piece ladder, make sphere and conical contact, add tighten nut again, fix the upper and lower end of dabber on gear grinding machines, fix the upper and lower end of dabber on gear grinding machines. The utility model has the advantages of it is following: this frock simple structure, it is convenient to dismantle, and the gerar grinding precision is high, and efficient, low in manufacturing cost is applicable to ordinary gear grinding machines, for example, gear grinders with worm -shaped grinding wheel, shaping gear grinding machines etc..
Description
Technical field
The utility model relates to machining equipment, is specifically related to one and is arranged in gear grinding machines, carries out the frock of roll flute to hole gear in ladder.
Background technology
Making gear teeth face reach high-precision processing method is exactly roll flute, and the existing frock of gear grinding machines generally can only process the gear of straight hole, be the gear of shoulder hole to inner hole, there is no special tooling, the mode in hole in artificial centering can only be taked, waste time and energy, comparatively bother, affect production efficiency, benefit can better do not created for enterprise.Existing gear grinding tooling be an axis of cone and opening sleeve with the use of, opening sleeve is arranged in the axis of cone, is arranged on opening sleeve by straight hole gear, and can not meet roll flute requirement to hole gear in the shorter ladder of length.
Summary of the invention
The purpose of this utility model is to provide gear gear grinding tooling in hole in a kind of ladder, just can carry out the frock of roll flute to hole gear in ladder on common gear grinding machines, and install simple, roll flute process stabilization, precision is high, efficiency is high.
Gear gear grinding tooling in hole in the ladder of the design, for gear grinding machines, comprise mandrel, clip, packing ring, nut, it is characterized in that gear grinding tooling structure: mandrel lower plane center hole adds clip, is positioned on mandrel second, four major diameter round platform by hole gear large footpath nose end in workpiece ladder, and in workpiece ladder construction opening pad, taper faced washer, spheric washer successively on hole gear diameter holes end face, make sphere and taper-face contact, then add nut screwing clamping; The upper and lower end of mandrel is fixed on gear grinding machines; The upper and lower end of mandrel is fixed on gear grinding machines.
The utility model has the following advantages: this tool structure is simple, convenient disassembly, and precision of grinding teeth is high, and efficiency is high, low cost of manufacture, is applicable to common gear grinding machines, such as, and gear grinding machine with worm grinding wheel, molding gear grinding machine etc.

Detailed description of the invention
Hole gear grinding tooling in the utility model ladder, for gear grinding machines, comprise mandrel, clip, packing ring, nut, it is characterized in that gear grinding tooling structure: mandrel 1 lower plane center hole adds clip 6, is positioned on mandrel 1 second, four major diameter B, D round platform by the large footpath of hole gear 7 in workpiece ladder nose end, and in workpiece ladder construction opening pad 2, taper faced washer 3, spheric washer 4 successively on hole gear 7 diameter holes end face, make sphere and taper-face contact, add nut 5 again to tighten, make workpiece shoulder hole gear 7 be fixed on shoulder hole gear grinding tooling; The upper and lower end of mandrel 1 is fixed on gear grinding machines.
Fig. 2 is the assembled state of this gear grinding tooling: open washer 2, taper faced washer 3, sphere 4 are standard component, and respective aperture, the center of circle and the sixth-largest diameter compatible of mandrel 1 close.Mandrel 1 is multiple not isometrical cylinders, mandrel 1 shown in Fig. 3 has 7 continuous one of diameter, cylinder upper and lower end is plane, there is centre bore at two ends, from lower end the fifth-largest diameter E be upwards the 3rd successively, maximum gauge C, A, maximum gauge A is upwards adjacent is second, the 4th, the sixth-largest diameter, the 7th minimum diameter B, D, F, G, the 7th minimum diameter G is the other end; Have groove between maximum gauge A and second largest diameter B, groove is arranged at the sixth-largest nearly bottom of diameter F, each diameter edge is chamfering, and between each diameter, change forms round platform.
See Fig. 4 a, 4b, clip 6 is like land shape, and ring has disconnection mouth, and outer rim has multiple gap and reducing round platform.Clip 6 endoporus and mandrel 1 are matched in clearance.
Method of operating: hole one side in large for hole gear 7 in workpiece ladder footpath is arranged on the maximum and second largest external diameter of mandrel, open washer 2 to be arranged in workpiece ladder hole one side in hole gear 7 path, the plane side of taper faced washer 3 is arranged on open washer 2, the sphere side of spheric washer 4 is arranged on the steep-taper face of taper faced washer 3, make sphere and taper-face contact, nut 5 is screwed on bolt, by the lower plane center hole of the sub-assembly of hole gear 7 and described frock in workpiece ladder by mandrel 1, the center hole of clip 6 and upper plane is fixed on gear grinding machines, fastening nut 5.At this moment gear grinding machines just can carry out roll flute to workpiece shoulder hole gear 7.
