Description

Drilling and slotting device for crankshaft

Technical Field

The utility model relates to the field of machining, in particular to a drilling and slotting device for a crankshaft.

Background

The crankshaft of the refrigerator compressor transfers motion to convert the rotary motion of a motor into reciprocating linear motion of a piston, and also bears the function of an oil pump, so that engine oil at the bottom of the shell is sucked in the motion process and then is conveyed to each kinematic pair through small oil holes, oil grooves and the like of the crankshaft, and a good lubricating effect is provided for each kinematic pair. Therefore, the angle of the crankshaft main shaft oil hole and the positions of the center of the opening part of the crankshaft main shaft oil hole and the center of the main shaft directly influence the whole oil pumping effect.

The existing hole turning machine tool directly places a workpiece on a tool and then directly performs drilling work, so that the stability of the workpiece during drilling cannot be guaranteed while potential safety hazards exist, and the final yield of the workpiece is influenced.

Therefore, a new technical solution is needed to solve the above problems.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects in the prior art, the utility model aims to provide a drilling and slotting device for a crankshaft.

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a drilling fluting device for bent axle, includes the workstation, the fixed surface of workstation is connected with the fixed plate of two vertical settings, be provided with the positioning seat between the fixed plate, the both ends of positioning seat are provided with to rotate to be connected in the pivot of fixed plate, install on the fixed plate and be used for driving positioning seat pivoted motor, the surface of positioning seat is provided with locating component.

Through adopting above-mentioned technical scheme, when carrying out production processing, place the work piece level on the positioning seat, and through locating component in order to play the positioning action to the work piece, the material loading is accomplished the back, drive the positioning seat through the motor and rotate, make the angle of work piece take place to deflect, make it be in the angle that corresponds with drilling equipment, so that to punch work to it, punch and accomplish the back, the motor drives the positioning seat and resets, so that unload and the material loading of next time to it, the stability of work piece when effectively having promoted production security and drilling.

The utility model is further configured to: the locating component comprises a plurality of locating plates fixedly connected to the surface of the locating seat, locating holes are formed in the locating plates, lower locating blocks corresponding to the locating plates are arranged on the surface of the locating seat, V-shaped grooves are formed in the lower locating blocks, door-shaped supports are arranged on the locating seat, air cylinders are installed at the tops of the door-shaped supports, the end portions of piston rods of the air cylinders vertically penetrate through the door-shaped supports downwards and are fixedly connected with connecting rods, and a plurality of upper locating blocks corresponding to the locating blocks are installed on the lower surfaces of the connecting rods.

Through adopting above-mentioned technical scheme, insert the locating hole through the one end with the bent axle to be located V type inslot, the flange one end butt of bent axle in the locating plate, the material loading of being convenient for drives the connecting rod through the cylinder and moves towards the work piece, makes every go up the locating piece and supports tightly in the work piece, in order to play the positioning action to the work piece, has effectively promoted the stability of work piece when punching the work.
