An extrusion threaded sleeve 108 is sleeved outside the three clamping heads 109, and the extrusion threaded sleeve 108 is used for extruding the three clamping heads 109, wherein the extrusion threaded sleeve 108 is threadedly sleeved on the clamping head mounting seat 107, and the extrusion threaded sleeve 108 can be axially moved on the clamping head mounting seat 107 by rotating the extrusion threaded sleeve 108, so as to extrude the three clamping heads 109. A through hole is formed in the arc-shaped support plate 104 and can be penetrated by the extrusion threaded sleeve 108, and a hexagonal column boss convenient for a wrench to clamp is arranged on the circumferential surface of the extrusion threaded sleeve 108. A shielding sleeve ring adjusting motor 127 is also fixedly installed on the circumferential surface of the polishing protection negative pressure chamber 125, a friction roller 128 is fixedly installed on an output shaft of the shielding sleeve ring adjusting motor 127, and the friction roller 128 is in rolling friction transmission cooperation with the shielding sleeve ring 126.

[0029] The working principle of the multi-axis linkage intelligent drill bit grinding system disclosed in the application is as follows: the two adjusting sliding plates 103 extrude the arc-shaped support plate 104, so that the arc-shaped support plate 104 can only be arc-shapedly slid under resistance of the two adjusting sliding plates 103, for improving stability, and the sliding positions of the adjusting sliding plates 103 and the arc-shaped support plate 104 are provided with scale marks, for providing swing angle information of the arc-shaped support plate 104 on the adjusting sliding plates 103.

[0030] The drill bit to be ground is inserted between the three clamping heads 109, and then the wrench is used to rotate the extrusion threaded sleeve 108 (the output shaft of the grinding rotary motor 106 needs to be fixed, for example, a tab is inserted into the gap between the two adjacent clamping heads 109 and clamped), so that the three clamping heads 109 clamp the drill bit, and then the swing threaded cylinder 105 is tightened on the arc-shaped support plate 104, before which the appropriate size of the air inlet through hole 111 needs to be selected according to the size of the drill bit to align with the oval hole 137. Specifically, the shielding sleeve ring adjusting motor 127 is controlled, the output shaft of the shielding sleeve ring adjusting motor 127 drives the friction roller 128 to rotate, the friction roller 128 drives the shielding sleeve ring 126 to rotate on the grinding protection negative pressure chamber 125, so that different air inlet through holes 111 are aligned with the oval hole 137. At this time, only the drill bit needs to pass through the air inlet through hole 111 to extend into the grinding protection negative pressure chamber 125, so that the drill bit is in contact with the circumferential surface of the grinding body 139 (the end point of the drill bit is located directly above the grinding body 139). The extension rod of the feeding electric cylinder 112 is controlled, and the feeding electric cylinder 112 drives the grinding protection negative pressure chamber 125 to move upward, and then drives the surface of the grinding body 139 to contact the drill bit (the diameter of the air inlet through hole 111 is larger than the diameter of the drill bit, so that a small range of displacement is allowed, and a gap for air intake between the air inlet through hole 111 and the drill bit is required).

[0031] The driving motor 115 is started, the output shaft of the driving motor 115 drives the center gear 120 to rotate, the center gear 120 drives the gear disc 121 to rotate through the planetary gear 119, since the gear disc 121 is connected to the polishing body 139 (the load is large), at this time the resistance required for the rotation of the gear disc 121 is large, therefore the three planetary gears 119 will revolve, the planetary gear 119 revolves back to drive the feedback pulley disc 116 to rotate (the feedback pulley disc 116 is in rotation cooperation with the output shaft of the driving motor 115, or no cooperation relationship), the feedback pulley disc 116 drives the input shaft of the gearbox 113 to rotate through the transmission belt 117, the output shaft of the gearbox 113 drives the negative pressure driving shaft 136 to rotate, the negative pressure driving shaft 136 drives the counterweight swing arm support ring 135 and the centrifugal turbine 131 to rotate, wherein the centrifugal turbine 131 rotates back to suck the air in the polishing protection negative pressure chamber 125 into the air suction negative pressure chamber 114 (the external air enters the inside of the polishing protection negative pressure chamber 125 through the air inlet through hole 111 and the gap and the elliptical hole 137 of the drill bit, then the flowing air carries the ground dust to enter the air suction negative pressure chamber 114 through the slag discharge channel 138, the corrugated pipe 129 and the connecting channel nozzle 130 in turn), so that the inside of the polishing protection negative pressure chamber 125 is in a negative pressure environment, and the air is thrown into the exhaust pipe 118 by centrifugal force, and then guided to the inside of the filter bag 102 through the exhaust pipe 118, and the filter bag 102 filters and separates the air and the ground dust (at this time, the polishing has not started or the polishing speed is relatively slow). As the rotating speed of the centrifugal turbine 131 continuously increases, the centrifugal turbine 131 will reach the maximum rotating speed, at this time the suction force of the centrifugal turbine 131 is the largest. The rotation of the counterweight swing arm support ring 135 will also drive the counterweight swing arm 134 to rotate, the counterweight swing arm 134 rotates and swings outward under the action of the centrifugal force, so that the friction limiting roller 133 and the friction limiting ring 132 are extruded, the rolling friction between the friction limiting roller 133 and the friction limiting ring 132 is increased, and then the rotating resistance of the counterweight swing arm support ring 135, the negative pressure driving shaft 136 and the centrifugal turbine 131 is increased, and the resistance will react on the feedback pulley disc 116, thereby limiting the revolution of the planetary gear 119, at this time more power is transmitted to the gear disc 121, the gear disc 121 transmits power to the first sliding turntable 122, the rotation of the first sliding turntable 122 drives the second sliding turntable 124 to rotate through the intermediate sliding turntable 123, the second sliding turntable 124 drives the polishing body 139 to rotate, so that the relative sliding between the polishing body 139 and the drill bit occurs, and then the grinding of the polishing body 139 to the drill bit is realized, and the grinding is fed through the feed cylinder 112. In this process, since the axis of the first sliding turntable 122 is offset from the axis of the second sliding turntable 124, the first sliding turntable 122, the intermediate sliding turntable 123 and the second sliding turntable 124 will constantly slide back and forth to ensure smooth power transmission.

[0032] According to the parameters of the drill bit, the swing thread cylinder 105 is swung, the angle between the end of the drill bit (the grinding part) and the surface of the polishing body 139 is controlled. This process will have resistance to the sliding of the arc-shaped support plate 104 between the two adjusting sliding plates 103, and the swing thread cylinder 105 needs to be held by hand during polishing, or a locking screw is installed to fix the position of the arc-shaped support plate 104 and the adjusting sliding plate 103. Start the polishing rotary motor 106, and the output shaft of the polishing rotary motor 106 drives the drill bit to rotate through the clamping head mounting seat 107 and the clamping head 109, which is used to make different parts of the drill bit contact with the polishing body 139.
