The turntable 4 is disposed above the swing seat 1 and sleeved thereon for placing parts. A grinding wheel is provided on the other side of the device main body for machining the parts on the turntable 4. By adjusting the push rod assembly 3, the inclination angles of the swing seat 1 and the turntable 4 are changed, so as to change the machining angle between the parts and the grinding wheel.

[0035] As Figure 2 shown, the swing seat 1 is in a circular ring shape. One end thereof is provided with a rotating seat 11 for connecting with the rotating shaft 2, and the other end thereof is provided with a fixed seat 12 for connecting with the push rod assembly 3.

One end of the first screw rod 33 abuts against the device main body. By rotating the first screw rod 33, the inclination angle of the swing seat 1 is adjusted.

[0037] In this embodiment, the connection end of the first screw rod 33 and the device main body is in an arc shape, so as to adapt to the change of the contact surface between it and the device main body when the inclination angle of the swing seat 1 changes. A gasket can also be provided between the first screw rod 33 and the device main body to prevent the first screw rod 33 from damaging the device main body.

[0038] As Figure 4 shown, in order to ensure the stability of the swing seat 1 after the push rod assembly 3 is adjusted, fixing components 5 are further provided on both sides of the fixed seat 12. The fixing components 5 include fixing plates 51. The fixing plates 51 are in an L shape. One side limb plate thereof is fixedly connected to the device main body, and the other side limb plate is provided with a long hole 52 along its axial direction. It is connected to the holes on both sides of the fixed seat 12 through a second screw rod 53 that passes through the long hole 52.

[0039] In this embodiment, in order to facilitate adjusting the inclination degree of the swing seat 1, a scale is provided on the fixing plate 51 close to the fixing seat 12 side, and a pointer pointing to the scale is provided on the fixing seat 12.

[0040] As Figure 5 shown, a collection groove 6 is provided between the swing seat 1 and the turntable 4, which is arranged around the turntable 4. The bottom of the collection groove 6 is connected to the swing seat 1, and its upper part is connected to the turntable 4.

[0041] In this embodiment, the swing seat 1 is provided with an opening to facilitate chip removal.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0043] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
