[0011] Preferably, the support is fixedly mounted on the top of the movable plate, a sleeve is movably mounted inside the support, and a rotating structure is formed between the sleeve and the support, a handle is fixedly mounted on one side of the sleeve, and an extrusion block is rotatably mounted on one side of the sleeve.

[0012] Preferably, a fixing groove is movably installed at one end of the extrusion block, the fixing groove and the extrusion block are threadedly connected, and teeth are arranged on the outside of the extrusion block. The internal shape of the fixing groove is narrow at the front and wide at the back, and a fixing block is movably installed inside the fixing groove.

[0014] A grinding method of a grinding device for high-hardness cutting drill bit processing, comprising the following steps:

[0015] S1. Insert the fixing block into the fixing groove, and then insert the positioning pin on one side of the fixing groove into the positioning groove outside the sleeve, rotate the extrusion block half a circle to preliminarily fix the fixing groove through the threaded connection, and then insert the workpiece into the fixing block, start the second servo motor to drive the worm to rotate, when the two sets of worms rotate in the same direction, the turbine will not rotate but will move longitudinally with the rotation, so that the base connected to it slides along the connecting rod, driving the support to move to a suitable position, when the worm rotates in the opposite direction, the turbine rotates so that the spur gear on its top rotates at the same time, driving the movable plate meshing with it to move laterally, so that the fixed support on its top is close to the grinding head;

[0016] S2. During the movement of the support, the first gear on the side wall of the movable plate continuously approaches the rack at one end. When it moves to the meshing state, the first gear rotates through the second right-angle gear set to drive the second gear to rotate. The second gear meshes with the teeth on the outside of the extrusion block. The rotation of the second gear drives the extrusion block to rotate. Under the action of the threaded connection, the fixed groove continuously approaches and merges with the extrusion block. Because its internal shape is narrow at the front and wide at the back, when the fixed groove approaches, the fixed block is pressed by the extrusion block and cannot move, so it continuously moves toward the outer end of the fixed groove. The outer end of the fixed block is open, and when it is squeezed by the inside of the fixed groove, it contracts to limit and fix the workpiece inside. When the support moves to the front end of the grinding head, the teeth on the rack end, and the extrusion block and the fixed groove are locked, otherwise they are loosened, so that the workpiece can be fixed and disassembled while moving.

[0017] S3. Start the first servo motor to drive the grinding head to rotate, and grind the workpiece that moves to contact with it. At the same time, the handle can be rotated to drive the workpiece to rotate. When the first servo motor is turned on, the connecting shaft connected to its output end through the pulley mechanism rotates at the same time, so that the first right-angle gear set at one end rotates, and the fan blades are driven to rotate at high speed through the pulley mechanism, so that suction is generated in the groove at the bottom of the grinding head, and most of the iron filings under grinding are adsorbed and collected on the filter plate, making the surface of the workbench tidier. At the same time, the rotation of the connecting shaft drives the reciprocating screw to rotate through the pulley mechanism, so that its external slide is moved back and forth, driving the push rod and brush plate fixed to it to move forward and backward. The brush plate brushes back and forth on the surface of the filter plate to collect the iron filings on the surface to the side to prevent the accumulation of iron filings from affecting the wind speed circulation of the filter plate.

[0018] The invention provides a grinding device for high-hardness cutting drill bit processing and a grinding method thereof, which have the advantages of:

[0019] By providing a dust collection structure, when the first servo motor is turned on to drive the grinding head to rotate, the connecting shaft is driven to rotate at the same time through the pulley mechanism, so that the first right-angle gear set rotates through the pulley mechanism to drive the fan blade to rotate at high speed, which will generate a force on the air around it, so that the air enters the workbench from the groove at the bottom of the grinding head and then is discharged, thereby generating a similar adsorption force, and most of the iron filings under grinding are adsorbed and collected on the filter plate, thereby keeping the grinding device for drill bit processing clean and avoiding adhesion to the surface or inside of the equipment to affect the normal operation of the equipment. At the same time, the collected iron filings can be recycled and reused, optimizing the production process and improving production efficiency;

[0020] Furthermore, when the connecting shaft rotates, the reciprocating screw rod is driven to rotate through the pulley mechanism, so that the slide outside thereof moves back and forth, driving the push rod and the brush plate fixed thereto to move forward and backward. The brush plate moves back and forth on the surface of the filter plate, collecting the iron filings on the surface to the side, avoiding the accumulation of iron filings that affects the wind speed of the filter plate, improving the filtration efficiency, and ensuring the effective collection of iron filings.

[0021] By providing an extrusion block, during the movement of the support, when the first gear on the side wall of the movable plate is close to the rack at one end to mesh, the first gear rotates through the second right-angle gear set to drive the second gear to rotate, so that the extrusion block meshing therewith rotates, and under the action of the threaded connection, the fixed groove is driven to continuously approach and merge toward the extrusion block. Because its internal shape is narrow at the front and wide at the back, the outer end of the fixed block is open, and when it is squeezed inside the fixed groove, it contracts to limit and fix the workpiece inside. When the support moves to the front end of the grinding head, the teeth on the rack end, and the extrusion block and the fixed groove are locked. On the contrary, when the support is away from the grinding head, it is loosened and the workpiece can be taken out, thereby realizing that the grinding device for drill processing can fix and disassemble the workpiece while displacing, simplifying the operation and improving the processing efficiency.

Under the action of the threaded connection, the fixed groove (52) continuously approaches and merges with the extrusion block (53). The internal shape is narrow at the front and wide at the back. When the fixing groove (52) is close, the fixing block (54) is pressed by the squeezing block (53) and cannot move, so it continuously moves toward the outer end of the fixing groove (52). The outer end of the fixing block (54) is open. When it is squeezed by the inside of the fixing groove (52), it contracts to limit and fix the workpiece inside. When the support (5) moves to the front end of the grinding head (2), the teeth on the rack (532) end, and the squeezing block (53) and the fixing groove (52) are locked. Otherwise, they are loosened, so that the workpiece can be fixed and disassembled while moving. S3. Start the first servo motor (21) to drive the grinding head (2) to rotate, and grind the workpiece that moves to contact with it. At the same time, the handle (51) can be rotated to drive the workpiece to rotate. When the first servo motor (21) is turned on, the connecting shaft (35) connected to its output end through the pulley mechanism rotates at the same time, so that the first right-angle gear set (33) at one end thereof rotates, and the fan blade (32) is driven to rotate at high speed through the pulley mechanism, so that suction is generated at the groove at the bottom of the grinding head (2), and the grinding Most of the iron filings cut off are adsorbed and collected on the filter plate (31), making the surface of the workbench (1) neater. At the same time, the connecting shaft (35) rotates through the pulley mechanism to drive the reciprocating screw rod (34) to rotate, so that the slide (341) outside thereof moves back and forth, driving the push rod (342) and the brush plate (343) fixed thereto to move forward and backward. The brush plate (343) brushes back and forth on the surface of the filter plate (31), collecting the iron filings on the surface to the side, thereby preventing the iron filings from accumulating and affecting the wind speed flow of the filter plate (31).
