Abstract
The utility model relates to a piston pin hole processing device which comprises a machine tool body. The piston pin hole processing device is characterized in that the machine tool body is provided with a piston tool unit and hole boring units, the piston tool unit is used for positioning a piston vertically and provided with a rough hole boring station and a fine hole boring station, the piston arranged on the piston tool unit is fed into an air cylinder through a tool arranged on the piston tool unit to realize the change of the rough hole boring station and the fine hole boring station; the hole boring units comprise two rough pin hole boring units and a fine pin hole boring unit, wherein the two rough pin hole boring units have the structure that the piston is arranged on the rough hole boring station, and the fine pin hole boring unit has the structure that the piston is arranged on the fine hole boring station; and the rough pin hole boring units and the fine pin hole boring unit are all provided with hole boring rods and driving mechanisms for driving the hole boring rods to rotate and feed. Because the rough hole boring and the fine hole boring of the pistons are finished through one-time clamping, the positioning errors caused by multiple-time clamping can be avoided, the pin hole processing precision requirement can be guaranteed, the pin hole processing efficiency can be improved.
Description
Technical field
The utility model relates to a kind of piston pin hole processing unit (plant).
Background technology
The function of piston is to bear gas pressure, and passes to connecting rod through piston pin and order about crankshaft rotating, and top land still is the part of combustion chamber.So play the piston pin hole processing that the influences engine compression ratio particular importance that seems, yet all there are deficiencies such as machining accuracy is not high, production efficiency is low in existing domestic and international piston manufacturing industry to the processing of piston pin hole.
Summary of the invention
The purpose of the utility model is to provide a kind of piston pin hole processing unit (plant), and this piston pin hole processing unit (plant) structural design is ingenious, guarantees machining accuracy when helping enhancing productivity.
The utility model piston pin hole processing unit (plant); Comprise machine tool main body; It is characterized in that: said machine tool main body is provided with the piston frock unit and the bore hole unit of vertical positioning piston; Said piston frock unit is provided with rough bore station and right boring hole station, and the said piston that is installed on the piston frock unit is realized the transposing of rough bore station and right boring hole station through being installed in frock feeding cylinder on this unit; Said bore hole unit comprises that piston is arranged on two heavy boring pin-and-hole unit of rough bore station and the unit, right boring hole that piston is arranged on the rough bore station, is equipped with boring bar on said heavy boring pin-and-hole unit and the precision bored hole unit and boring bar rotates and the driving mechanism of feeding in order to drive.
Rotate through motor and the belt pulley drive mechanism boring bar that is arranged on its side on above-mentioned heavy boring pin-and-hole unit and the precision bored hole unit.
Drive the boring bar feeding through the servo-drive system that is arranged on its rear side on above-mentioned heavy boring pin-and-hole unit and the precision bored hole unit.
The operation principle of the utility model is adding man-hour, with the piston piston frock unit of packing into; Start machine tool main body, the clamp mechanism clamping piston, this moment, piston was in the rough bore station; Be positioned at the heavy boring pin-and-hole unit feeding heavy boring bar of piston both sides, piston is carried out rough bore processing; After this, frock feeding cylinder is adjusted to right boring hole station with piston frock unit, is positioned at the precision bored hole unit feeding right boring bar of piston side, and piston is carried out rough bore processing.Because piston promptly accomplishes its rough bore and precise boring in a clamping, help the position error of avoiding multiple clamping to cause, thereby guaranteed the required precision of pin-and-hole processing, also improved the production efficiency of pin-and-hole processing.
Description of drawings
Fig. 1 is the utility model organigram.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be specified.
The utility model piston pin hole processing unit (plant); Comprise machine tool main body 1; Machine tool main body 1 is provided with the piston frock unit 2 and bore hole unit 3 of vertical positioning piston; Piston frock unit 2 is provided with rough bore station 4 and right boring hole station 5, and the piston 6 that is installed on the piston frock unit is realized the transposing of rough bore stations 4 and right boring hole station 5 through being installed in frock feeding cylinder 7 on this unit; Bore hole unit 3 comprises that two heavy boring pin-and-hole unit 8 that piston is arranged on the rough bore station and piston are arranged on the unit, right boring hole 9 of rough bore station, is equipped with boring bar 10 on heavy boring pin-and-hole unit and the precision bored hole unit and in order to drive the driving mechanism 11 of boring bar rotation and feeding.
In order to realize that boring bar rotates, drive the boring bars rotation through motor and the belt pulley driving mechanism 12 that is arranged on its side on above-mentioned heavy boring pin-and-hole unit 8 and the precision bored hole unit 9.
Drive the boring bar feeding through the servo-drive system 13 that is arranged on its rear side on above-mentioned heavy boring pin-and-hole unit and the precision bored hole unit.
The operation principle of the utility model is adding man-hour, with the piston piston frock unit of packing into; Start machine tool main body, the clamp mechanism clamping piston, this moment, piston was in the rough bore station; Be positioned at the heavy boring pin-and-hole unit feeding heavy boring bar of piston both sides, piston is carried out rough bore processing; After this, frock feeding cylinder is adjusted to right boring hole station with piston frock unit, is positioned at the precision bored hole unit feeding right boring bar of piston side, and piston is carried out rough bore processing.Because piston promptly accomplishes its rough bore and precise boring in a clamping, help the position error of avoiding multiple clamping to cause, thereby guaranteed the required precision of pin-and-hole processing, also improved the production efficiency of pin-and-hole processing.
Though the utility model preferred embodiment has disclosed as above, be not in order to qualification the utility model, anyone all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
