Technical field
The utility model relates to a kind of piston pin hole process tool, is specifically related to a kind of two-way Novel piston pin aperture knife tool.Belong to engine and accessory technical field of processing equipment thereof.
Background technology
Piston is the key components and parts of engine, and the heat resistance of piston, wearability, guidance quality and good sealing property can reduce the frictional work loss of engine stably, reduce oil consumption, noise and pollution.Pin-and-hole size on piston can affect the sealing property of piston, and is therefore high to the pin-and-hole required precision of piston, and the circularity of piston pin hole and cylindricity require all below 5um.Existing piston pin hole process tool for cylindricity and the circularity precision of the piston pin hole that improves piston pin hole, generally all will carry out right boring processing to pin-and-hole.Borer is mainly that two blades are installed on a knife bar, carries out respectively semifinishing and fine finishining by two blades.But there is following shortcoming in borer:
1, adopt two blades simultaneously cylindricity and the circularity of the piston pin hole of piston pin hole to be carried out semifinishing and fine finishining, as shown in Figure 1, for two blades are installed, therefore the length of knife bar is longer, the rigidity of knife bar is low, thereby affect machining accuracy, adopt the high material of rigidity to make the production cost that knife bar has increased again cutter.
2, because of between fine finishining blade and piston pin hole apart from close proximity, again because knife bar is longer, the rigidity of knife bar is low, at piston pin hole during at withdrawing, the fine finishining blade easily scratches pin-and-hole, thereby affects cylindricity and the circularity precision of pin-and-hole, does not contact with piston pin hole in order to make two blades, process velocity is slow when withdrawing, as shown in Figure 2.
3, when the processing dimension of pin-and-hole during less than φ 17, corresponding knife bar size reduction, the rigidity of knife bar reduces, and cylindricity and the circularity in hole can not be guaranteed.
The utility model content
The purpose of this utility model is, for overcome existing tool sharpening low precision, working (machining) efficiency is low and the high in cost of production defective, and a kind of two-way type piston pin hole process tool is provided, this cutter simple in structure, the rigidity of cutter is strong, machining accuracy is high and production cost is low.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of two-way type piston pin hole process tool, comprise knife bar and driving mechanism, it is characterized in that: the front end of knife bar is connected with the output of driving mechanism, be provided with a blade in the rear end of knife bar, the rigidity of knife bar improves by shortening its length, driving mechanism has two and advances the formula control structure, by this two blade secondary cutting workpiece when workpiece enters and withdraw from station that advances on formula control structure control knife bar, forms two-way type process tool structure.
The purpose of this utility model can be also to be achieved through the following technical solutions:
Further scheme of the present utility model: described driving mechanism is hydraulic mechanism, is made of hydraulic controller and oil cylinder, and the output of hydraulic controller connects the input of oil cylinder, and the clutch end of oil cylinder connects the driving input of knife bar.
Further scheme of the present utility model: described driving mechanism is made of cyclelog and stepper motor, and the control output end of cyclelog connects the control input end of stepper motor, and the clutch end of stepper motor connects the driving input of knife bar.
The beneficial effects of the utility model:
1, driving mechanism of the present utility model has two and advances the formula control structure, by this two blade secondary cutting workpiece when workpiece enters and withdraw from station that advances on formula control structure control knife bar, form two-way type process tool structure, therefore, only need to arrange a blade on knife bar, just can realize the fine finishining to workpiece, by reducing the length that arranges to have shortened knife bar of blade, thereby improve machining accuracy and the working (machining) efficiency of rigidity and the raising cutter of knife bar, guaranteed cylindricity and the circularity precision of piston pin hole.
2, the utility model only need arrange a blade, and the rigidity of knife bar is able to improve by shortening its length, therefore, has reduced the requirement to the knife bar rigid material, thereby has reduced the production cost of cutter.
