Detailed description of the invention
As shown in Figure 1, the stock axle double channel milling and paring supporting arrangement of frame and water pump bearing, supporting seat is fixed on fixed base plate.The supporting seat left and right sides is respectively arranged with the lower support for locating up and down stock shaft-like work and locates the upper support of stock shaft-like work for front and back.Supporting seat right side is provided with end face locating shaft, and end face locating shaft is fixed on end face positioning seat.Supporting seat opposite side is provided with motor, motor connection of rotating driving lever, and rotating lever is connected with stock shaft-like work by heart pawl.Supporting seat connects depression bar by little minor axis, and depression bar can rotate by little minor axis.Supporting seat is connected with the working end of depression bar by spring.On depression bar, be provided with handle.The working end of depression bar is provided with bearing block, is provided with compression bearing on bearing block.The cross section of the end face of described compression bearing and stock shaft-like work has angle.Angle direction is determined according to the direction of rotation of stock shaft-like work, should ensure that stock shaft-like work is close to end face locating shaft.
Described end face positioning seat, motor are fixed on fixed base plate.
Under actual working state, motor is fixedly connected with fixed base plate screw.Between rotating lever and motor, screw is fixed, and between rotating lever and heart pawl, screw is connected and fixed.Heart pawl and stock shaft-like work are fixed by screw.Stock shaft-like work right-hand member presses end face locating shaft.The external diameter difference end face of two upper supports and the end face of two lower supports of stock shaft-like work are tangent, and the external diameter of stock shaft-like work also contacts with the external diameter that compresses bearing.It is that the end face of described compression bearing and the cross section of stock shaft-like work have angle that the compression axis of bearing and the axis of stock shaft-like work have certain angle.Supporting base is connected with fixed base plate screw, and end face locating shaft is screwed on end face positioning seat, and end face positioning seat is connected with fixed base plate screw.Upper support is connected with supporting base screw, and lower support is connected with supporting base screw.Compress bearing and be fixed on bearing block, bearing block is connected with depression bar screw.On spring 15 compression column with fixed working ends, one end, the other end is fixed on little major axis, and little major axis is arranged on supporting base.Little minor axis is arranged on supporting base, and the rotary hole of depression bar is arranged on little minor axis, and handle is screwed on depression bar.Be fixed on the emery wheel driving on rotating shaft near stock shaft-like work grinding raceway groove.
When work, the rotation of motor is passed heart pawl is also rotated for it by rotating lever, and heart pawl drives again stock shaft-like work to rotate.Stock shaft-like work compresses end face locating shaft, and the external diameter of stock shaft-like work is tangent with the end face of upper support and the end face of lower support respectively, and the external diameter of stock shaft-like work also contacts with the external diameter that compresses bearing.Compress the axis of bearing and the axis of stock shaft-like work and have certain angle, in the process of rotating at stock shaft-like work, compressing bearing also rotates for it, there is certain angle owing to compressing the axis of bearing and the axis of stock shaft-like work, make to compress bearing component of axial generation to stock shaft-like work in rotation process, this component makes stock shaft-like work and end face locating shaft in Grinding Process, remain the state of being adjacent to, thereby has ensured the axial location precision of stock shaft-like work in grinding process.Raceway groove on stock shaft-like work is ground to while setting size, removes emery wheel, presses down handle, compresses bearing and lifts, and takes off the stock shaft-like work processing, and changes unprocessed stock shaft-like work and again carries out grinding.
Upper support, lower support and supporting base are all connected by screw.By adjusting two lower supports of supporting base both sides, can ensure that stock shaft-like work axle center is high consistent to the center of two emery wheels; By adjusting two upper supports of supporting base both sides, can ensure that stock shaft-like work axle center is consistent to the depth of parallelism of two emery wheels; Thereby ensure the radial location precision of stock shaft-like work in grinding process.
The utility model avoids stock shaft-like work in axial, the circular runout that use in wheel grinding double channel process, has ensured Product Precision.
