And the method of operation and use, etc., are described in further detail to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concepts and technical solutions of the present invention.

As shown in Figure 1 to Figure 3, there are three views (front view, top view and left view) when the special jig for boring machining of the robot turntable clamps the robot turntable. In the figure, there are three through holes on the clamp body 1. They are the first through hole, the second through hole and the third through hole respectively. The axes of the first through hole, the second through hole and the third through hole are all perpendicular to the clamp body 1 , the positioning pin 4 is installed in the first through hole, and the axis of the positioning pin 4 is perpendicular to the clamp body 1 . The positioning pin 4 extends out of the clamp body 1 and passes through the fourth through hole on the support plate 2 to enter the positioning hole on the robot swivel base. The clamp body 1 is also provided with a support plate 2, the support plate 2 is an annular structure, the inner hole of the support plate 2 is called the fourth through hole, and the diameter of the fourth through hole of the support plate 2 is larger than that of the positioning pin 4. The outer diameter is large, and the axis of the fourth through hole of the support plate 2 coincides with the axis of the positioning pin 4 . The robot swivel seat is installed on the support plate 2, and the robot swivel seat and the support plate 2 form a surface fit. The robot swivel base is limited by a surface on the support plate 2 and the positioning pin 4 to five degrees of freedom, and there is another degree of freedom that rotates around the axis of the supporting positioning pin 4 without limitation. A positioning plate 3 is arranged on the clamp body 1, the distance between the positioning plate 3 and the axis of the positioning pin 4 is smaller than the radius of gyration of the robot turn base rotating around the axis of the positioning pin 4, and the positioning plate 3 is perpendicular to the clamp body 1. The maximum height of the positioning plate 3 is less than the sum of the height of the robot turntable and the thickness of the supporting plate 2 , and the minimum height of the positioning plate 3 is greater than the thickness of the supporting plate 2 . Positioning plate 3 limits the degree of freedom that robot swivel base rotates around support pin 4 axis. Therefore, the six degrees of freedom of the robot swivel seat in space are limited by the special jig for boring processing of the robot swivel seat, so the positioning of the special jig for boring processing of the robot swivel seat is complete positioning.

A clamping device is also provided on the clamp body 1 , and the clamping device includes a nut 5 , a washer 6 , a spring 7 , a pressing plate 8 , a guide rod 9 and a support column 10 .

The part that guide rod 9 stretches out clamp body 1 is longer than the part that support column 10 stretches out clamp body 1, and the end that guide rod 9 stretches out clamp body 1 is provided with the external thread that cooperates with the internal thread on the nut 5, and guide rod 9 The part protruding from the clip body 1 passes through the spring 7 , the waist hole 11 , and the washer 6 sequentially, and the guide rod 9 passes through one end of the washer 6 and is connected with the nut 5 .

The pressure plate 8 is provided with a waist hole 11, the length direction of the waist hole 11 is the same as the length direction of the pressure plate 8, the length of the waist hole 11 is smaller than the length of the pressure plate 8, and the upper end of the pressure plate 8 is provided with a pressure point 12, and the other end is provided with a guide Groove 13, the direction of the guide groove 13 is consistent with the length direction of the pressure plate 8, the width of the guide groove 13 is equal to the diameter of the support column 10, the pressure plate 8 is arranged on the support column 10 through the guide groove 13. The pressure plate 8 is installed on the guide rod 9 through the waist hole 11. The guide rod 2 is also provided with a gasket 6, a spring 7 and a nut 5. The gasket 4 is installed between the pressure plate 8 and the spring. between.

When clamped by the special jig for boring machining of the robot turntable, the pressure plate 8 is installed on the guide rod 9 through the waist hole 11, the pressure point 12 of the pressure plate 8 is pressed on the robot turntable, and the guide groove 13 of the pressure plate 8 is pressed on the support column 10. The gasket 6 is placed on the area between the pressure plate 8 and the nut 5 on the guide rod 9, and the nut 5 applies a force to the gasket 6 along the guide rod 9 to the clamp body 1 through the external thread on the guide rod 9, and the gasket 6 will force Conducted to the pressing plate 8, the pressing plate 8 then compresses the robot swivel seat and the support column 10.

The special jig for boring machining of the robot turntable is from the clamped state to the relaxed state, loosen the nut 5, and move the pressure plate 8 along the guide groove 13 and the waist hole 11 to the direction away from the robot turntable until the pressure plate 8 is on the clamp body 1 When the vertical projection of the vertical projection of the robot does not contact with the vertical projection of the robot swivel seat on the clamp body 3, the movement of the pressing plate 8 is stopped, and the robot swivel seat can be taken out from the special fixture.
