Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of workpiece machining, in particular to a precision machining boring-milling-polishing integrated machine tool. BACKGROUND

[0002] In the field of precision machining, milling is a common process in workpiece machining, and the polishing process after milling is a key subsequent step to ensure the surface precision of the workpiece groove, eliminate milling burrs and flash, and directly affect the assembly performance and service life of the workpiece. After the workpiece is milled by a special milling equipment, it is transferred to a separate polishing equipment for subsequent polishing operation.

[0003] Firstly, after the workpiece is milled, it needs to be clamped and fixed again when it is transferred to the polishing equipment. In the secondary clamping process, not only a lot of manual operation time is consumed, but also machining errors are easily caused by clamping and positioning deviation, affecting the position accuracy and size consistency of the groove. Secondly, after the workpiece is fixed again, the grinding head of the polishing equipment needs to be calibrated again, and the feed value of the grinding head needs to be reconstructed according to the groove parameters. This calibration and parameter setting process is tedious, which further prolongs the processing cycle and reduces the production efficiency.

[0004] Especially critical is that in the rough grinding stage, in order to ensure the grinding effect, the grinding tool rotation direction needs to be reasonably matched with the milling cutter rotation direction (such as reverse collision to improve the efficiency of excess removal), which requires the operator to record the rotation direction parameter of the milling cutter after the milling process is completed, and then transfer the parameter to the polishing process, and adjust the grinding tool rotation direction of the polishing equipment. This process not only increases the operation steps, but also may cause improper grinding tool rotation setting due to parameter recording or transmission error, thereby affecting the rough grinding efficiency, and even causing quality problems such as groove surface scratching and texture residue.

[0028] During operation, the workpiece is first fixed on the workbench 1, the lifting frame 3 is controlled to slide horizontally by the horizontal lead screw rail in the interior of the gantry 2, the mounting frame 10 is lifted and lowered by cooperating with the vertical lead screw rail in the interior of the lifting frame 3, so as to adjust the mounting frame 7 to be above the workpiece processing area, then the control cylinder 9 is started to drive the milling shaft 19 to descend to the working position, the milling shaft 19 is rotated by the control motor 8, the milling cutter on the milling cutter mounting head 4 completes the milling and grinding, after the milling and grinding is completed, the milling shaft 19 is lifted and reset by the control cylinder 9, the mounting frame 7 is lowered by the mounting frame 10, so that the grinding tool on the grinding head mounting head 14 reaches the milling and grinding position, the grinding shaft 11 is rotated by the control motor 8 to complete the grinding operation, finally the lifting frame 3 and the mounting frame 10 are adjusted to reset, and the processed workpiece is taken out.

[0031] The inner wall of the mounting frame 7 is fixedly installed with a support collar 21, the upper end of the support collar 21 is rotatably installed with a driven wheel 17, the support collar 21 provides support for the driven wheel 17.

[0032] The driven wheel 17 is connected with the driving wheel 12 through a transmission member, in the embodiment, the transmission member is a common belt, the driving wheel 12 and the driven wheel 17 are connected through the belt, so that the driven wheel 17 is controlled to rotate when the driving wheel 12 rotates.

[0033] The bottom surface of the driven wheel 17 is rotatably installed with a guide collar 23 through a one-way bearing, the guide collar 23 remains stationary when the driven wheel 17 rotates in the positive direction, the guide collar 23 synchronously rotates in the reverse direction when the driven wheel 17 rotates in the reverse direction.

[0034] The outer wall of the milling shaft 19 is fixedly installed with a guide strip 20, the guide strip 20 is slidably connected with the guide collar 23, the outer wall of the guide strip 20 is slidably attached to the inner wall of the guide collar 23, so as to facilitate the sliding of the milling shaft 19, and at the same time, the guide collar 23 drives the milling shaft 19 to rotate when it rotates.

[0036] After the workpiece is fixed on the loading platform 1, the control cylinder 9 is started to drive its movable end to descend to the working position together with the milling shaft 19, at this time, the control motor 8 reversely rotates and drives the driving wheel 12 on the output shaft to synchronously rotate in the reverse direction, the driving wheel 12 is connected with the grinding shaft 11 through a one-way bearing, the grinding shaft 11 remains stationary in this reverse rotation state, at the same time, the driving wheel 12 drives the driven wheel 17 at the upper end of the support collar 21 to reversely rotate through the belt transmission, the guide collar 23 connected with the bottom surface of the driven wheel 17 reversely rotates synchronously, thereby driving the milling shaft 19 to rotate, and the milling groove processing is completed by the milling cutter on the milling cutter mounting head 4.
