The adjusting screw 19 is further sleeved with a pressing spring 20, the lower end of the pressing spring 20 is fixed with the grinding seat 51, and the upper end of the pressing spring 20 presses against the guide seat 181, so that the guide seat 181 has an upward trend.
After the grinding disc 52 is used for a long time, the inclined surface 521 of the grinding disc 52 is partially worn due to grinding, and at this time, the inclined surface 521 of the grinding disc 52 is corrected by the sharpening device. In practice, the axis of grinding disc 52 is moved above tool holder 172, and then grinding table 51 is moved downward so that the lowest segment of grinding disc 52 is aligned with tool 172. At this time, the motor drives the adjusting screw rod 19 to rotate, so that the guide column 182 of the guide seat 181 moves downwards, the guide column 182 passes through the vertical groove 1712 and enters the guide groove 1711, then the grinding seat 51 moves downwards, and in the process of moving the grinding seat 51 downwards, the dressing seat 171 moves through the matching of the guide column 182 and the guide groove 1711, so that the tool 172 corrects the inclined surface 521 of the grinding disc 52. When the grinding disc 52 grinds the workpiece, the guide 18 is not used, and the guide seat 181 is driven to move upwards by the adjusting screw rod 19, so that the grinding of the workpiece is not influenced by the fact that the guide 18 is abutted to the workpiece.
Alternatively, the dresser disk 171 may be fixed directly to the table 3, and the cutter 172 may be fixed to the dresser disk 171. In this case, the correction of the inclined surface 521 of the grinding disc 52 can also be realized by the movement of the grinding carriage 51 in the vertical direction in conjunction with the movement of the XY-moving table in the Y-axis, in which case the guide 18 is not required.
The working principle of the embodiment is as follows:
when the workpiece needs to be polished, the workpiece is firstly arranged on the mounting seat 4, then the side wall of the tooth part to be polished of the workpiece is adjusted to be parallel to the sliding direction of the workbench 3 through the rotation of the mounting seat 4, the tool setting is realized by moving the XY-axis moving platform 2 and the grinding device 5, so that the grinding disc 52 is aligned with the side wall of the tooth part of the workpiece to be ground, then the work piece to be ground tooth sidewall is moved by the reciprocating movement of the table 3 in the X-axis direction, when the side wall of the tooth to be ground of the workpiece passes through the position of the grinding disc 52, the inclined surface 521 of the grinding disc 52 is used for grinding the tooth to be ground of the workpiece, after the front end surface is ground, the installation seat 4 rotates to enable the next end face to be polished to rotate to be parallel to the X-axis direction, the workbench 3 moves along the X-axis direction to conduct grinding, the side walls of all tooth portions of the workpiece are polished in sequence, and therefore the accuracy of the side walls of the end face tooth portions of the workpiece is improved.
The embodiment of the application also discloses a method for polishing the end face teeth for the turret, which comprises the following steps:
s1, assembling the workpiece, referring to fig. 5, the positioning gear ring 23 and the fixed gear ring 24 are coaxially sleeved, then the teeth of the pressing gear ring 25 are engaged with the teeth of the positioning gear ring 23 and the fixed gear ring 24, pressure is applied to the pressing gear ring 25 to align the teeth of the positioning gear ring 23 and the fixed gear ring 24, then the positioning gear ring 23 and the fixed gear ring 24 are fixed by bolts, and the pressing gear ring 25 is removed.
And S2, mounting the workpiece, mounting the assembled workpiece to the positioning groove 421 of the mounting seat 4, and fixing the workpiece on the positioning groove 421 through a bolt.
S3, correcting the workpiece, abutting the detection meter 62 on the circumferential outer wall of the workpiece, driving the worm 10 to rotate through the stepping motor 11, so that the worm wheel 9 rotates to drive the mounting seat 4 to rotate, and determining the position deviation by observing the change of the number of the detection meter 62. The position of the workpiece is finely adjusted by knocking the circumferential outer wall of the workpiece until the coaxiality deviation between the axis of the workpiece and the rotating axis of the mounting seat 4 is within 0.02 mm.
And S4, adjusting the position, namely rotating the mounting seat 4 to enable the side wall of the tooth part to be ground of the workpiece to be parallel to the X-axis direction of the moving platform, adjusting the workpiece to a required position through the XY moving platform, and enabling the inclined surface 521 of the grinding disc 52 to be just ground to the side wall of the tooth part of the workpiece through the up-down movement of the grinding device 5.
And S5, grinding, namely moving the XY-axis moving platform 2 along the X-axis direction to grind the workpiece, and rotating the mounting seat 4 by a corresponding angle after each movement in the X-axis direction, so that the next tooth part side wall to be ground rotates to a state parallel to the X-axis direction, thereby grinding each tooth part side wall of the workpiece.
