step three, moving a grinding wheel (3) to be replaced onto a discharge cover (24) and releasing, firstly, starting a horizontal screw rod module and an infrared displacement sensor (26), starting the horizontal screw rod module by a control terminal (7), driving a moving block (18) to move towards the grinding wheel (3), driving a mounting cylinder (16) and an electric sucking disc (15) on the mounting cylinder to move towards the grinding wheel (3) by the moving block (18) through a sliding shaft (17), and monitoring the moving distance of the electric sucking disc (15) by the infrared displacement sensor (26), and when the electric sucking disc (15) moves to the side wall of the grinding wheel (3), closing the horizontal screw rod module and starting the electric sucking disc (15), and adsorbing and fixing the grinding wheel (3) on a wheel shaft (4) by the electric sucking disc (15); secondly, starting the horizontal screw rod module again, wherein the horizontal screw rod module drives the electric sucking disc (15) to move reversely, and simultaneously, the infrared displacement sensor (26) monitors the position of the electric sucking disc (15) in real time; thirdly, when the infrared displacement sensor (26) monitors that the electric suction disc (15) drives the grinding wheel (3) to move above the discharge cover (24), the horizontal screw rod module and the electric suction disc (15) are closed, the replaced grinding wheel (3) is released, and the replaced grinding wheel (3) enters the discharge cover (24);
step four, picking up the grinding wheel (3) to be replaced, starting the horizontal screw rod module again by the control terminal (7), closing the horizontal screw rod module and starting the electric suction cup (15) when the electric suction cup (15) is monitored by the infrared displacement sensor (26) to move to the side wall of the grinding wheel (3) in the grinding wheel storage cylinder (25), and adsorbing and fixing the grinding wheel (3) to be replaced;
step five, mounting the picked-up grinding wheel (3) to be replaced on the wheel shaft (4) and separating, starting the horizontal screw rod module again by the control terminal, driving the grinding wheel (3) to be replaced to move towards the wheel shaft (4) by the electric suction disc (15), and closing the electric suction disc (15) when the electric suction disc (15) is monitored by the infrared displacement sensor (26) to drive the grinding wheel (3) to be replaced to move onto the wheel shaft (4), and driving the electric suction disc (15) to move back to the initial position again by the horizontal screw rod module to realize separating;
step six, locking the grinding wheel (3) to be replaced, starting an electric telescopic rod (14) by a control terminal (7), driving a locking block (11) to extend out of a wheel shaft (4) through a traction rod (12) by the electric telescopic rod (14) and abutting against the outer wall of the grinding wheel (3) to be replaced, and fixing the grinding wheel (3) to be replaced in an extrusion mode;
the horizontal screw rod module comprises a driving screw rod (19) in threaded connection with the moving block (18), the driving screw rod (19) is connected with a screw rod motor, the screw rod motor is fixedly connected with a support frame (27) fixedly connected with the machine tool seat (1), a horizontal sliding chute for the moving block (18) to transversely slide is formed in the support frame (27), and a rack plate (21) is fixedly connected with the support frame (27) and is arranged in parallel with the guide sliding chute plate (23);
the limiting block (22) is a rectangular block with four corners being rounded corners, the through sliding groove comprises a wide groove with a rectangular middle part and narrow grooves which are positioned at two sides of the wide groove and communicated with the wide groove, the vertical height of the wide groove is larger than the length of the limiting block (22), the vertical height of the narrow groove is larger than the width of the limiting block (22) and smaller than the length of the limiting block (22), and the joint of the wide groove and the narrow groove is in a chamfer shape.
2. A blade grinding machine according to claim 1, characterized in that the wheel housing (8) is of an open semi-encircling arcuate shape, the wheel axle (4) extending through the wheel housing (8) and being rotatably connected thereto.
3. The blade grinding machine according to claim 1, wherein the discharge cover (24) is bent at a right angle and has a lower end extending to the outside of the machine tool base (1), and the lower end of the discharge cover (24) is provided with an upper opening.
