[0021] Figure 1 、 2The novel machine is particularly suitable for use in production areas with small production scale and limited budget, and has the advantages of small size, low cost, relatively few components, small space occupation, and relatively simple operation. Before processing, the pulley blank is vertically placed in the middle of the upper end of the fixed seat 8. After the power module A1 is powered on, the stable DC 24V power supply output from the 3, 4 pins of the power module A1 enters the power input end of the power switches K1, K2, K3 and the alarm mechanism. After the handle of the power switch K3 is pulled left or right by the worker, the 1, 2 pins and the 3, 4 pins or the 5, 6 pins of the power switch K3 are connected, so that the positive and negative or negative and positive power input ends of the electric push rod M3 are powered on. After the positive and negative power input ends of the electric push rod M3 are powered on, the push column of the electric push rod M3 drives the pressure head 6 and the like to move downward, and the lower side end of the pressure plate 61 presses the upper end of the blank 11, and then the power switch is turned off, and the subsequent process of cutting the pulley groove can be performed. After the negative and positive power input ends of the electric push rod M3 are powered on, the push column of the electric push rod M3 drives the pressure head 6 and the like to move upward, and the lower side end of the pressure plate 61 no longer presses the upper end of the blank 11, and then the power switch is turned off, and the processed pulley can be taken out. After the handle of the power switch K1 or K2 is pulled left or right by the worker, the 1, 2 pins and the 3, 4 pins or the 5, 6 pins of the power switch K1 or K2 are connected, so that the positive and negative or negative and positive power input ends of the electric linear slide M1 or M2 are powered on. After the positive and negative power input ends of the electric linear slide M1 or M2 are powered on, the sliding block of the electric linear slide M1 or M2 drives the cutter mechanism to move left or upward to approach the upper part of the right side end of the blank, and then the power switch is turned off. After the negative and positive power input ends of the electric linear slide M1 or M2 are powered on, the sliding block of the electric linear slide M1 or M2 drives the cutter mechanism to move right (after the cutter left end and the blank are separated after the machining of one pulley groove 111 or all pulley grooves 111, the cutter left end and the blank need to be separated) or downward to approach the lower part of the right side end of the blank (another pulley groove machining is performed on the lower end of the blank, and in actual conditions, the cutter needs to be controlled to move right and separated from the blank first, and then controlled to move downward by a distance and move left to contact the right side of the blank to machine the next blank pulley groove 111), and then the power switch is turned off. Through the above, the worker can conveniently control the cutter left end blade to contact the right side of the blank 11 from top to bottom according to the need, and the cutter can machine the pulley groove 111 of the blank, and after the machining is completed, the cutter and the blank are separated to complete the whole machining process (the blank 11 is machined by the cutter from top to bottom for multiple pulley grooves 111).In the processing, after the power switch K is turned on, the motor speed reduction mechanism M is powered, and the power output shaft thereof drives the blank 11 to rotate clockwise (the cutter blade contacts the right side end of the blank), so that, since the left side end of the cutter blade contacts the blank 11, a wheel groove 111 is gradually formed when the blank rotates (after the wheel groove is formed, the power switch K is turned off, and then the cutter blade is lowered in height through the power switches K1 and K2 to process the next wheel groove, until all the wheel grooves are processed; in the specific processing, the staff needs to control the left end blade of the cutter to move left at intervals, so that the processed wheel groove has a certain depth; in the processing, the upper end of the blank 11 drives the pressure head and the pressure plate to rotate along the inner ring of the bearing seat, and the electric push rod does not rotate). Before processing, the staff opens the manual valve 31 of the coolant tank (the opening and closing degree of the valve core can adjust the amount of coolant entering the cutter blade), and the coolant output by the coolant tank 3 drops on the blade of the cutter to cool the cutter (the dropped coolant liquid enters the liquid receiving disc 13, and then is uniformly treated in the waste liquid barrel).

[0022] Figure 1 、 2 When the cutter is normally cooled by the coolant, the temperature of the cutter is relatively low (for example, lower than 300°C), the internal contact of the temperature switch W is open, so that the buzzer BX does not get electricity and sound, which represents that the cutter is not over-temperature. When the temperature of the cutter exceeds the standard due to various reasons (for example, higher than 300°C), the internal contact of the temperature switch W is closed, so that the buzzer BX gets electricity and sounds, which represents that the cutter is over-temperature, and the staff can process in time (for example, adding coolant when the coolant is used up, or dredging the pipeline when the coolant pipeline is blocked), thereby reducing the damage of the cutter and the probability of unqualified quality of the processed wheel groove.
