In addition, the second and third slide rail units 22 and 23 adopt a hydrostatic slide rail unit, so that the rails 222 and 232 and the slides 224 and 234 can be prevented from being heated and worn due to friction, thereby causing the precision of the grinder 10 to be lowered. The grinder 10 maintains good machining accuracy. It is worth mentioning that, since the first rail unit 21 does not affect the machining accuracy, it is not a hydrostatic slide unit in the embodiment, but the first rail unit 21 can also be a hydrostatic pressure. Slide unit.

In addition, the workpiece setting unit 30 can be more angularly rotated by the swinging device 60, so that the grinding machine 10 can perform other processing operations, such as inner hole taper grinding (as shown in FIG. 5), and Inner hole taper turning (as shown in Figure 7). The construction and actuation of the swing device 60 will be further explained below.

Referring to FIG. 8 , the swing device 60 includes a mounting assembly 61 , a turntable 62 , a motor 63 , a screw 64 , a nut 65 , a shaft 66 , two bearings 67 , and an optical scale 68 .

Please also refer to the ninth figure, the mounting assembly 61 includes a fixing A substrate 612 on one side of the slider 215, two mounts 614 fixed to the substrate 612, and a track 616 protruding from the substrate 612 and located between the two mounts 614.

Referring to the tenth figure, the turntable 62 includes a disk body 622 and a connecting rod 624. One end of the connecting rod 624 is fixed to one end of the disk body 622, and the connecting rod 624 has a disk from the other end thereof toward the disk. A long slot 624a that is recessed in the direction of the body 622. A circular protrusion 622a protrudes from the bottom of the disk 622, three arcuate protrusions 622b located at the periphery of the protrusion 622a, and two larger curved protrusions 622c located at the periphery of the protrusions 622b. The center of the circular protrusion 622a is further provided with a set of holes 622d.

In order to provide the turntable 62, a top surface 215a of the slide 215 is provided with a recess 215b. The recess 215b is provided with a circular protrusion 215c and a three-arc bump 215d at the periphery of the protrusion 215c. The center of the circular protrusion 215c protrudes more than a pivot 215e. The turntable 62 is sleeved on the pivot 215e of the slide 215, and can be swung around the pivot 215e, and the bumps 622a, 622b are coupled to the slide 215 The bumps 215c, 215d are in surface contact, and the bumps 622c are also in surface contact with the top surface 215a of the slider 215.

It should be noted that the pivotal relationship between the slider 215 and the turntable 62 is not limited to the one provided in this embodiment, as long as the turntable 62 can be pivoted relative to the slide 215 with a pivot as a center. For example, the slider 215 and the turntable 62 can also be respectively provided with a socket hole and a pivot shaft to be pivotally connected to each other. In addition, the turntable 62 is in surface contact with the slider 215 by the bumps 622a, 622b, and 622c, so that the turntable 62 can be smoothly disposed on the slide 215. The frictional resistance is too large due to the excessive contact area, but the contact relationship between the slider 215 and the turntable 62 is not limited to the one provided in this embodiment. Moreover, the long slot 624a does not have to be open at one end of the connecting rod 624, but may be a perforated shape of a closed shape.

The motor 63 is fixed to one of the mounting bases 614. The two ends of the screw 64 are rotatably passed through the two mounting bases 614 and can be driven by the motor 63.

The nut 65 is screwed to the screw 64 and is slidably embedded in the rail 616. The shaft 66 is fixed on the top of the nut 65. The two bearings 67 are fixedly disposed on the screw 65. A shaft 66, the shaft 66 and the bearings 67 are disposed in the long slot 624a of the turntable 62; whereby the nut 65 can be driven by the rotating screw 64 along the screw 64 and the track 616 Moving linearly, at the same time, the shaft 66 and the bearings 67 will rotate the rotating plate 62 relative to the sliding seat 215 as the nut 65 moves (as shown in the eleventh to thirteenth figures), and The bearings 67 will roll along the wall of the slot of the long slot 624a.

It is worth mentioning that the number of the bearings 67 provided by the shaft 66 is not limited, and the shaft 67 can be directly slid along the hole wall of the long slot 624a without the bearing 67, but the bearing 67 is provided. The design can reduce the friction and make the swing device 60 operate relatively smoothly. In addition, in this embodiment, the rail 616 is a ridge, and the nut 65 has a recess 652 embedded in the rail 616 (as shown in the ninth figure, wherein the nut 65 is partially cut away The 616 can also be a recess, and the nut 65 has a protrusion embedded in the rail 616. Moreover, the slider 215 can also be omitted. There is a track 616, but with the design of the track 616 enables the nut 65 to move more reliably in a straight line.

In the foregoing swinging device 60, the motor 63 can be a general equal-speed motor, and the position of the nut 65 can be controlled by controlling the position of the nut 65 without using an angle encoder, thereby controlling the turntable 62 to be rotated at a small angle. . Moreover, the optical scale 68 disposed under the screw 64 can sense the position of the nut 65, thereby controlling the motor 63 by feedback, so that the motor 63 can more accurately control the position of the nut 65, thereby accurately controlling the turntable 62. The angle of the swing. Regardless of whether or not the optical scale 68 is provided, the cost of the swinging device 60 is lower than that of the conventional swinging device controlled by the servo motor and the angle encoder.

In the present embodiment, the second cutter unit 50 is directly driven by the motor, however, the second cutter unit 50 can also be driven by the swing device 60 as described above. Moreover, the swing device 60 can also be replaced by a turntable and a motor that directly drives the turntable.

Since the action of the swinging device 60 improves the applicability of the grinder 10, the grinder 10 may not be provided with the swivel device 60, and the workpiece setting unit 30 may be directly disposed on the first rail unit 21. The slide 215 can also achieve the creative purpose of the creation, that is, maintain good machining precision, and use the same grinder to turn the workpiece and grind different parts, so as to save the labor of replacing the workpiece to different machines and time.

Finally, it must be explained again that the constituent elements disclosed in the foregoing embodiments are merely illustrative and are not intended to limit the scope of the present invention. Alternatives or variations of other equivalent elements should also be the scope of patent application of the present application. Covered.
