Abstract
The utility model provides a thin wall gear fluffing hole frock structure for internal grinding machine is last, including clamp plate, screw thread cylindric lock, bolt, packing ring, base, and its characterized in that package assembly: block the base excircle with chuck three -jaw chuck, put thin wall workpiece in base big hole, drop on on the circular slot, clamp plate right angle end is withstood to screw thread cylindric lock upper end to place each right periphery threaded hole of base wall in, each right interior all threaded hole during bolt and packing ring pass the clamp plate through -hole and insert the base wall, the threaded hole of the big pore wall of screw in base respectively, completed workpiece is fixed, living in thin wall workpiece with another wide end pressure of clamp plate, withstanding the clamp plate right -angle side with the screw thread cylindric lock, tighten the bolts fixes thin wall workpiece on the base simultaneously, hole in alright gerar grinding is taken turns. This frock simple structure, it is convenient to dismantle, and fluffing hole precision is high, and efficient, low in manufacturing cost is applicable to ordinary internal grinding machine, for example, M2120 internal grinding machine, 3A250 internal grinding machine.
Description
Technical field
This utility model relates to machining equipment, is specifically related to one and is arranged in internal grinder, thin-wall gear carries out the tool structure in fluffing hole。
Background technology
Make hole in gear reach mill in high-precision processing method is exactly, and the existing frock of internal grinder generally can only process the gear that wall thickness is thicker, if processing thin-wall gear, thin-walled specification limit diameter 300mm* wall thickness about 10mm, can make gear shifting quadrant texturing。Existing frock is scroll chuck, is directly clamped among on thin-wall gear, can cause that thin-wall gear deforms, and affects the accuracy of gear。
Summary of the invention
The purpose of this utility model is to provide a kind of thin-wall gear fluffing hole tool structure, it is possible to thin-wall gear carries out the frock of interior mill on internal grinder, installs simple, interior mill process stabilization, and precision is high, and efficiency is high。
A kind of thin-wall gear fluffing hole tool structure of the design, for internal grinder, including pressing plate, cylindrical pin with external thread, bolt, packing ring, base, it is characterised in that package assembly: block base cylindrical with chuck scroll chuck, thin-wall gear workpiece is placed in hole, base big footpath, drops on circular groove；Pressing plate right angle end is withstood in cylindrical pin with external thread upper end, in the periphery screwed hole of be placed in base wall each pair, bolt and packing ring, in the inner circumferential screwed hole of each pair in pressing plate through hole inserted base wall, screw in respectively in the screwed hole of the big hole wall of base, complete workpiece and fix；Live thin-wall gear workpiece by another wide side pressure of pressing plate, withstand pressing plate right-angle side with cylindrical pin with external thread, tight a bolt simultaneously, thin-wall gear workpiece is fixed on base, just can hole in roll flute wheel。
The design grinds the frock of thin-wall gear and well solves the problems referred to above, makes hole in thin-wall gear can be ground to its required precision。This utility model has the advantage that this tool structure is simple, convenient disassembly, and fluffing hole precision is high, and efficiency is high, low cost of manufacture, it is adaptable to plain grinding machine internal, for instance, M2120 internal grinder, 3A250 internal grinder。

Detailed description of the invention
This utility model thin-wall gear fluffing hole tool structure, for internal grinder, including pressing plate 2, cylindrical pin with external thread 4, bolt 5, packing ring 3, base 1, it is characterized in that package assembly: see Fig. 1, Fig. 2, block base 1 cylindrical with scroll chuck, thin-wall gear workpiece 6 is placed in the big hole, footpath of base 1, drops on circular groove；Pressing plate 2 right angle end is withstood in cylindrical pin with external thread 4 upper end, in the periphery screwed hole of be placed in base 1 wall each pair, bolt 5 and packing ring 3, in the inner circumferential screwed hole of each pair in pressing plate 2 through hole inserted base 1 wall, screw in respectively in the screwed hole of the big hole wall of base 1, complete workpiece and fix；Live thin-wall gear workpiece 6 by another wide side pressure of pressing plate 2, withstand pressing plate 2 right-angle side with cylindrical pin with external thread 4, tight a bolt 5 simultaneously, thin-wall gear workpiece 6 is fixed on base 1, just can roll flute wheel in hole。
The shape of base 1 see Fig. 3,4: base 1 is Rotary-table, and base 1 radially side is macropore, and opposite side is aperture, forms a circular groove between the concentric circle holes that two diameters do not wait；6 pairs of screwed holes it are uniformly distributed between height and the thickness of macropore and outer wall。
The shape of pressing plate 2 is shown in Fig. 5 a, 5b, and pressing plate 2 is main is considered as rectangle, long limit plane has long to ellipse hole, the wide rectangular shape of end in cross section one。
Cylindrical pin with external thread 4, bolt 5, packing ring 3 are standard component。
Operational approach: block tooling base 1 cylindrical with scroll chuck, thin-wall gear workpiece 6 is placed in the big footpath of tooling base 1 in hole, thin-wall gear workpiece 6 is pushed down with pressing plate 2, withstand pressing plate 2 right-angle side with cylindrical pin with external thread 4 simultaneously, tight a bolt 5, thin-wall gear workpiece 6 is fixed on base 1, just can roll flute wheel in hole。
