Referring to fig. 1 and 2, the spring 12 is vertically disposed below the platform 11, one end of the spring is connected to the platform 11, and the other end of the spring can be connected to the bottom plate 9 of the movable member 1, specifically, the bottom surface of the platform 11 and the upper surface of the bottom plate 9 are respectively provided with a groove, and two ends of the spring 12 are disposed in the grooves to limit two ends of the spring. When the device is not started, the platform 11 is kept horizontal by the action of the springs 12 on both sides. The spring 12 may apply a supporting force to the platform 11 in a compressed state or may apply a tensile force to the platform 11 in a stretched state.
Referring to fig. 1-3, the first clamping member 3 has an upwardly facing first clamping position 15, and the first clamping member 3 is supported on the platform 11 and is capable of rotating about a first longitudinal axis 16 coaxial with the first clamping position 15. For example, a chuck may be selected as the first clamping member 3. The chuck is a mechanical device used for clamping a workpiece on a machine tool, and is widely applied to machines such as lathes, cylindrical grinding machines, internal grinding machines and the like. The chuck jaws are centripetally movable, i.e. towards the first gripping position 15, and can grip the object placed in the first gripping position 15. Instead of the chuck type, the first clamping member 3 may be a centering type, a chuck type, an angle iron type, or a chuck type, etc.
The first clamping member 3 is supported in the middle of the platform 11, in particular directly above the axis of rotation 13. Referring to fig. 2, a second servo motor 17 is disposed below the platform 11, and the second servo motor 17 can drive the first clamping member 3 to rotate.
Referring to fig. 1-2, the second clamping member 4 has a second clamping position 18 facing downward, the second clamping member 4 is configured such that the second clamping position 18 can be moved close to above the first clamping position 15 and held opposite to the first clamping position 15, and the second clamping member 4 is further configured to be capable of rotating about a second longitudinal axis 19 coaxial with the second clamping position 18. For example, the second clamping member 4 is configured to clamp the object in a rotating motion and to be lifted and lowered above the first clamping member 3. In some embodiments, the second clamping member 4 is fixed on a motor shaft of a third servo motor 20, the third servo motor 20 is disposed on a mounting base 21, the mounting base 21 is connected with an air cylinder 22, and the air cylinder 22 drives the lifting and lowering of the mounting base.

During the match grinding process, the position of the second clamping member 4 is kept stationary. The first and second clamping members 3 and 4 are rotated in opposite directions, respectively, and the concave spherical surfaces 24 and the convex spherical surfaces 26 are ground with each other. The first servomotor 8 periodically rotates forward and backward, enabling the valve seat 23 clamped on the first clamping member 3 to reciprocate laterally within a certain range. When the first clamping member 3 moves transversely, the valve seat 23 is blocked by the valve core 25 to incline the platform 11 and the first clamping member 3, an offset angle is formed between the first longitudinal axis 16 and the second longitudinal axis 19, and accordingly the valve seat 23 is also inclined, which can change the matched grinding position, so that the matched grinding between the concave spherical surface 24 and the convex spherical surface 26 is more sufficient.
The valve seat and valve core spherical sealing surface grinding device disclosed by the utility model utilizes an object clamped by the second clamping component 4 with a constant position to apply an acting force on the object clamped by the moving first clamping component 3, so that the object clamped by the second clamping component is inclined, the grinding part between the two objects is adjusted in an all-around manner, and the grinding is more in place and comprehensive. Another great advantage of the present disclosure is low cost and low manufacturing difficulty. The user can assemble the device by himself without having to commission a special machine manufacturer. The valve seat and valve core spherical sealing surface grinding device has the advantages that the valve seat and valve core spherical sealing surface grinding device is easy to popularize and apply.
