Abstract
The utility model discloses a muller for the connecting bar tooth surface of a diesel engine, which comprises a stander, a cam, a revolving gear, a travel mechanism, a clamping rod and a table vice. A frequency-conversion electric motor-retarding mechanism as well as a guide holder and the table vice are respectively fixed on the stander by bolts; the cam is connected with the output shaft of the frequency-conversion electric motor-retarding mechanism through a straight key; a roller moving in a cam path is fixed on a shipper rod by a bolt; the shipper rod is limited in the hole of the guide holder; the clamping rod is hinged with the shipper rod by a pin, and an oscillating bearing is arranged on the clamping rod. Since no reversing collision exists, the rubbing motion can be very calm, and the connecting bar tooth surface can obtain perfect rubbing quality. The contacting area of a connecting rod cover and the connecting rod tooth surface can achieve the design requirement; the working efficiency of the muller for the connecting bar tooth surface of a diesel engine is high, and the technical level of the diesel engine manufacture industry in China is promoted.
Description
One, technical field
The utility model grinding mill for link lever tooth surface of diesel engine relates to a kind of link lever tooth surface of diesel engine grinding technique field, is applied to boats and ships, industries such as railway, power station, military equipment.
Two, background technology
Just at present domestic also do not have driving to be the grinding mill for link lever tooth surface of diesel engine of cam mechanism.In order to make connecting rod that good working performance be arranged, the profile of tooth faying face of diesel engine connecting bar lid and gonnecting rod body, general employing is manually ground, though Grinding Quality still can, operating efficiency is very low.The grinding mill for link lever tooth surface of diesel engine that adopts the external pneumatic actuation made of introducing technology is also arranged, and it is covered by the cylinder piston rod drivening rod and reciprocatingly on gonnecting rod body finishes grinding work, though operating efficiency is higher, and the Grinding Quality existing problems.Because when cylinder piston rod drivening rod lid moves forward to halt, cylinder piston rod is anxious under the control of pneumatic reversing piece to stop, when returning, because the unexpected variation of speed, inertia moves forward connecting rod cap, simultaneously, the pulling force of the cylinder piston rod after connecting rod cap is also commutated, this moment, connecting rod cap is at inertia forward and jumping phenomena can occur under the effect of pulling force backward.In like manner, when connecting rod cap moves rearwards to the halt commutation, also jumping phenomena can appear, be reflected on the Grinding Quality, it is low middle high that two can appear in the flank of tooth on the gonnecting rod body, can not guarantee that the connecting rod cap and the flank of tooth of gonnecting rod body have good applying to contact, can not reach the designing requirement of connecting rod, thereby influence the work of diesel engine.
Three. summary of the invention
The purpose of this utility model is in order to overcome above-mentioned defective, to improve the Grinding Quality and the production efficiency of link lever tooth surface of diesel engine, designing a kind of grinding mill for link lever tooth surface of diesel engine.Its technical being achieved in that comprises frame, the cam rotating mechanism, travel mechanism, supporting rod, bench vice is in interior structure, it is characterized in that: variable-frequency motor-decelerator, guide holder and bench vice are respectively by bolt, bolt, be bolted on the frame, cam is connected with the output shaft of variable-frequency motor-reductor by flat key, the roller that moves in cam path is screwed on carriage release lever, carriage release lever is limited in the hole of guide holder, cam path peak and minimum point respectively have one section concentric, but the circular arc that radius is different, supporting rod is provided with oscillating bearing, supporting rod is hinged with pin and carriage release lever, connecting rod cap is connected with supporting rod with bolt by pressing plate, supporting rod is reciprocating with the speed of 0～100m/min, and cam is with the speed rotation of 0～1250r/min.The positive effect of implementing this technology is: cam path respectively has one section to be the center of circle but the different circular arc of radius with the rotating shaft in peak and minimum point, during the carriage release lever commutation, roller on the carriage release lever is from touching a certain section arc groove on the cam path, before roller leaves this section arc groove, the displacement of carriage release lever, speed, acceleration are zero, inertia impact when having eliminated the connecting rod cap commutation that is associated in supporting rod makes that the grinding motion is very steady.The oscillating bearing that supporting rod is provided with can be adjusted the concentricity between supporting rod and the carriage release lever automatically, and can guarantee that the connecting rod cap and the gonnecting rod body flank of tooth remain the applying contact condition in process of lapping.The operating efficiency of grinding mill for link lever tooth surface of diesel engine is also very high.
