Detailed Description
As shown in FIG. 1, a processing device for a sine wave groove on a gluing surface in a crankshaft torsional damper of the present invention comprises: a tool 26, a transmission mechanism, a reciprocating mechanism 24 and a grooving cutter 25. The fixture 26 is mounted on the rotating spindle and is used for clamping the workpiece 10 to rotate. The transmission is used to transmit the torque of the rotating spindle to the power input of the shuttle 24. The power output end of the reciprocating mechanism 24 is connected with the slotting cutter 25 through a connecting rod and is used for driving the slotting cutter 25 to reciprocate along the direction parallel to the rotating main shaft. The cutting edge of the grooving cutter 25 is in contact with the gluing surface of the workpiece 10. The transmission mechanism comprises a driving wheel 21, a driven wheel 22 and a steering gear set 23. The driving wheel 21 is coaxially arranged on the rotating main shaft, and the driven wheel 22 is connected with the driving wheel 21, connected with the steering gear set 23 in series through a transmission rod and then connected to the power input end of the reciprocating mechanism 24. The reciprocating mechanism 24 is a cam structure or a crankshaft structure.
A processingequipment theory of operation that is arranged in bent axle to twist reverse among bumper shock absorber veneer surface sine wave groove lies in: first, a crankshaft torsion damper, i.e., a workpiece 10, is fixedly attached to an end of a rotation main shaft through a tool 26 such that the center of the workpiece 10 is coaxial with the rotation main shaft. Then the machine tool is started to output the rotating power, the driving wheel 21 drives the driven wheel 22 and the steering gear set 23 to input power to the reciprocating mechanism 24 in sequence, and the torque is converted into reciprocating power. The reciprocating mechanism 24 drives the grooving tool 25 to reciprocate in a direction parallel to the main axis of rotation, and the cutting edge contacts the surface, specifically the side surface, of the sine wave groove 11. Since the rotation of the workpiece 10 and the reciprocating movement of the grooving tool 25 are synchronized, the path of the grooving tool 25 on the surface of the workpiece 10 is the sine wave groove 11 to be machined.
On the basis of the technical scheme of the utility model, through the adjustment of parameters such as gear ratio, power output ratio, it is the common knowledge of the technical personnel in the field to obtain the sine wave groove 11 of different sizes. Meanwhile, the specific structure of the steering gear set 23 adopts different modes in specific use occasions, which is also common knowledge of those skilled in the art, and specifically, two trapezoidal gears can be adopted for orthogonal steering as shown in the drawing.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
