[0014] The preferred embodiments of the utility model are described in detail below in combination with the drawings, so that the advantages and features of the utility model can be more easily understood by the person skilled in the art, and the protection scope of the utility model is more clearly and explicitly defined.

[0015] Embodiment: please refer to Figures 1-2 The utility model provides a kind of technical scheme: a kind of quick clamping mechanism of clamping device for high-speed plane pre-grinding machine, including clamping device 1 and flange sleeve 2 and flange shaft 3, the center through hole of flange sleeve 2 passes through flange shaft 3 and is limited by shaft check ring 6, the inner wall of the center through hole of flange sleeve 2 is equipped with conical hole 7, the circumferential side of flange shaft 3 is evenly provided with a plurality of recesses for storing steel ball 9, the top center position of clamping device 1 is equipped with clamping shaft 4, the circumferential side of clamping shaft 4 is provided with steel ball limiting hole 8, the inside of flange shaft 3 is provided with clamping shaft insertion hole 12, the bottom circumferential side of flange shaft 3 is connected with limiting block 5, the upper of flange sleeve 2 is evenly provided with three spring grooves for installing spring 10, positioning pin 11 that passes through limiting block 5 is arranged in spring groove, and clamping device 1 is equipped with the positioning hole matched with positioning pin 11.

[0016] Positioning pin 11 is stepped positioning pin, and the diameter of one end of positioning pin 11 inserted into spring groove is greater than the diameter of spring 10; the diameter of the bottom of positioning pin 11 is less than the diameter of the top of positioning pin 11, and is arranged into stepped positioning pin, limiting block 5 is used to prevent positioning pin 11 from falling off from spring groove.

[0017] The top radius of the conical hole 7 is equal to the diameter of the steel ball 9 plus the radius of the holder shaft 4.

[0018] The bottom radius of the conical hole 7 is equal to the diameter of the steel ball 9 plus the radius of the holder shaft 4 minus the depth of the steel ball limiting hole 8.

[0019] The outer wall of the holder shaft 4 is in contact with the inner wall of the holder shaft insertion hole 12, and the depth of the holder shaft insertion hole 12 is greater than the length of the holder shaft 4.

[0020] The outer wall of the flange shaft 3 is in contact with the inner wall of the bottom of the conical hole 7.

[0021] Working principle: a quick clamping mechanism of a holder of a high-speed plane pre-grinding machine, the quick clamping mechanism of the holder is a mechanism that cooperates with a steel ball 9 and a spring 10, the center position of the holder 1 is connected with a holder shaft 4, the holder shaft 4 is provided with a groove, the steel ball 9 entering the groove will limit the holder shaft 4, preventing the holder shaft 4 from falling off from the holder shaft insertion hole 12, a flange shaft 3 with a ball socket is connected to the pre-grinding machine, and the flange shaft has three positioning pins for driving the holder 1. A flange sleeve 3 is sleeved above the flange shaft 3, and a conical hole is further arranged on the center hole of the flange sleeve 3; when the steel ball is placed in the ball socket of the flange shaft, the spring 10 pushes against the flange sleeve 2 (the normal state of the flange sleeve 2 is that the spring 10 pushes against it), at this time, the bottom end (the end with the smallest diameter) of the conical hole in the flange sleeve 2 is in contact with the steel ball 9, so that the steel ball 9 forms a spherical protrusion in the installation hole of the flange shaft 3, as shown in the figure, when the holder shaft 4 on the holder is inserted into the holder shaft insertion hole 12, the protrusion of the steel ball is just embedded in the groove on the holder shaft 4, thereby hanging the holder, realizing the clamping function. Figure 1

[0022] When the operator presses down the flange sleeve with his hand, the steel ball 9 slides into the top part (the end with the largest diameter) of the conical hole in the flange sleeve 2, the spherical protrusion of the inner hole of the flange shaft is invalid, and the holder shaft 4 on the holder can be taken off from the holder shaft insertion hole 12 in the flange shaft. The mechanism only needs to be pressed and released by the operator, thereby realizing the quick clamping and dismounting of the holder.
