The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and together with the description, serve to explain the principles of the disclosure.

Fig. 1 is a schematic view of the overall structure of the present invention.

Fig. 2 is a schematic view of the clamping block structure disclosed in the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Examples

Referring to fig. 1-2, the CNC precision machining clamping and positioning device includes a positioning support platform 20, a material supporting assembly and a positioning clamping assembly, a base platform 10, and a driving rotary seat and a driven rotary seat disposed on both sides above the base platform, both sides of the positioning support platform are correspondingly fixed with the driving rotary seat and the driven rotary seat, a positioning groove 30 is cut on the middle portion of the positioning support platform, the whole height of the positioning groove is less than the height of the valve seat, and both upper and lower surfaces of the valve seat can be exposed outside the positioning groove, the positioning clamping assembly includes four rotary screws 50 and four clamping blocks 40, the four rotary screws extend into the positioning groove from the outside of the positioning support platform in pairs, and each rotary screw is fixed with a clamping block inside the positioning groove, the material supporting assembly includes a material supporting cylinder 60 and a material supporting plate 70, the material supporting cylinder is fixed above the base corresponding to the lower side of the positioning groove, and the telescopic shaft of the material supporting cylinder is fixed with, when the material supporting cylinder drives the material supporting plate to rise, an operator can directly put down the valve seat from the positioning groove, the bottom of the valve seat can be in contact with the supporting plate at the moment, and the operation of the operator through operating the four rotary screw rods is facilitated at the moment, so that the four clamping blocks clamp the valve seat.

In this embodiment, the initiative roating seat includes pedestal one 100, rotating electrical machines 80, reduction gear 90 and initiative rotation axis 110, rotating electrical machines's output shaft and reduction gear rigid coupling, the output and the initiative rotation axis of reduction gear are connected, and the rotatory pedestal one that passes of initiative rotation axis sets up, driven roating seat includes pedestal two 130, locate bearing frame 120 and driven rotation axis 140 in the pedestal two, driven rotation axis and bearing frame swivelling joint, all be connected with the L shape mounting panel 150 that is used for the fixed location plummer on initiative rotation axis and the driven rotation axis, when the rotatory motor drive initiative rotation axis rotates, the location plummer then can be followed the rotation, just can realize just at this moment changing the face processing to fixing the disk seat in the constant head tank.
