In the process of dispatching, the process is required to be repeated continuously until the polished product reaches the expected effect, and the dispatching process can be completed, because the polished magnetic steel is taken down under the traditional condition, the surface of the polished magnetic steel is subjected to roughness detection, and then the roughness can be reduced according to the detection result, the process is usually completed by the experience of a dispatching master, the roughness of the surface of the magnetic steel is caused by various reasons, the polishing speed of the polishing mechanism 3 is reduced, namely the polishing rotating speed, the polishing effect is better when the polishing rotating speed is higher under the same condition, the feeding amount of the polishing mechanism 3 is also influenced when the rotating speed and the feeding amount of the polishing mechanism 3 are too high, the polishing effect is burnt when the rotating speed and the feeding amount of the polishing mechanism 3 are too high, the assembling and debugging of a plurality of devices are required, the polishing time is caused by the experience of the dispatching master, the equipment is seriously prolonged, the time of the dispatching of the devices is shortened, the polishing mechanism is shortened, the polishing speed of the polishing mechanism is reduced, the polishing mechanism is required to be reduced when the detecting the magnetic steel 7, the surface of the magnetic steel is detected, the surface is required to be reduced, and the surface roughness is required to be reduced when the rotating speed of the polishing mechanism is not required to be higher than the target 3, and the surface is required to be detected. Meanwhile, in the process of machine adjustment, the grinding wheel is possibly passivated due to overlong service time of the grinding wheel, the grinding effect is influenced, the grinding wheel is needed to be trimmed, the grinding wheel is kept continuously sharp, and the influence of external factors on the result of machine adjustment is reduced.
In order to better control the feeding amount of the polishing mechanism 3, in this embodiment, the feeding mechanism 6 includes a driving component 61 and a sliding component 62, the driving component 61 is mounted on the top surface of the machine table 1, the polishing mechanism 3 is mounted at the sliding end of the sliding component 62, the driving end of the driving component 61 and the sliding end of the sliding component 62 are connected and drive the sliding component 62 to slide, when the detecting mechanism 7 detects the condition of burning of the magnetic steel surface, the driving component 61 adjusts the feeding amount, if the burning occurs when the grinding amount is small, the longitudinal feeding speed should be increased: burn occurs when the grinding amount is large, the feeding amount should be reduced, and the grinding times should be increased.
For accurate control of the feed amount, in an embodiment, the driving assembly 61 includes a stepper motor 611 and a worm screw lifter 612, the worm screw lifter 612 is mounted on the top surface of the machine 1 and is located at one side of the machine 1, the output axis of the worm screw lifter 612 is perpendicular to the feeding direction of the feeding mechanism 2, the input end of the worm screw lifter 612 is connected with the stepper motor 611, the output end of the worm screw lifter 612 is in spiral connection with the sliding end of the sliding assembly 62, the stepper motor 611 is in communication connection with the detection mechanism 7, the worm screw lifter 612 can be equipped with a hand wheel, the output end can be directly driven to rotate by the hand wheel, and the external driver can automatically control the output end to rotate, so that the manual control manner reserved under the condition of realizing electric control is achieved, and the grinding machine can have two control manners.
Because the stepper motor 611 is a device that converts an electrical pulse signal into an angular displacement or a linear displacement. The rotational speed and the movement distance of the stepper motor 611 are dependent on the frequency and the number of control electrical pulses without overload. Meanwhile, the precision of the transmission mode of the worm wheel screw rod adopted by the worm wheel screw rod lifter 612 is much higher than that of the traditional reducer adopting a gear meshing mode, because the worm wheel screw rod can realize zero backlash when in transmission, and the meshing of gears cannot achieve the effect, the transmission precision of the worm wheel screw rod is far greater than that of the gear meshing, and the transmission precision of the worm wheel screw rod is matched with the stepping motor 611 to finish driving, so that the feeding quantity of the feeding mechanism 6 can reach the precision of +/-0.01 mm, and meanwhile, the worm wheel screw rod lifter 612 has the advantages of compact structure, small size, light weight, wide power source, low noise and the like compared with the traditional double-control mode of adopting a reducer and a hand wheel to control the feeding, and the stepping motor 611 can enable the sliding component 62 to better control the sliding distance when in sliding, namely can better control the feeding quantity of the polishing mechanism 3, so that the factor affecting the polishing effect due to the driving component 61 can be reduced when the driving mechanism 3 to feed, and the machine is more convenient.
In order to enable the polishing mechanism 3 to complete feeding under the driving of the driving component 61, in an embodiment, the sliding component 62 includes a base 621 and a sliding block 622, the polishing mechanism 3 is mounted on the sliding block 622, the sliding block 622 is in spiral connection with the output end of the worm screw lifter 612, a sliding table 623 is disposed on the top surface of the base 621, a sliding groove 624 is disposed on the bottom surface of the sliding block 622, the sliding table 623 is in sliding connection with the sliding groove 624, and when the stepping motor 611 drives the worm screw lifter 612 to rotate, the sliding block 622 can slide on the base 621 to complete feeding of the polishing mechanism 3.
In order to reduce the vibration generated when the motor in the polishing mechanism 3 rotates, in one embodiment, the sliding groove 624 is a dovetail groove, the bottom surface of the sliding groove 624 is provided with the connecting block 8, the connecting block 8 is connected with the output end of the worm screw lifter 612, the sliding groove 624 is designed to match with the sliding block 622, because the dovetail groove generally acts on the structure of the relative motion of the machine, the function of reducing friction resistance is achieved, because the surface of the guide rail is smooth, and in practice, the guide rail does not have too much friction during operation, so that the friction coefficient can be reduced further, after the friction coefficient is reduced, the guide rail can be controlled to a better degree, and the guide rail can be used in places with larger precision machining requirements, so that the requirement of dimensional accuracy can be met. The guide rail is matched with the feeding mechanism 6, the movement distance of the guide rail can be better controlled through the control of the feeding mechanism 6, and the speed can be adjusted, so that the accuracy of the guide rail is further improved. The dovetail groove guide rail has certain rigidity, which means that the dovetail groove guide rail can have weighing capacity, and very heavy equipment or very heavy materials such as the like can be placed on the dovetail groove guide rail, so that very good accuracy of moving direction can be maintained. The guide rail can move at a high speed or at a low speed when being used, and the speed can be controlled at will. Thereby better engaging the drive assembly 61 to control the accuracy of the feed.
In order to make the sliding block 622 smoother in the sliding process, in an embodiment, a pad 625 is disposed on one side of the dovetail groove, the pad 625 abuts against a side wall surface of the dovetail groove and is slidably connected with the sliding table 623, because the sliding block 622 needs to support the polishing mechanism 3, the polishing mechanism 3 is larger in size, in order to make the sliding block 622 smoothly slide under the driving of the feeding mechanism 6 to realize smaller feeding amount, the size of the sliding block 622 and the size of the base 621 need to be matched with the size of the polishing mechanism 3, when the sliding table 623 and the dovetail groove are opened on a large workpiece, one step of processing errors can be realized, and the larger workpiece has larger errors during the reprocessing, so that in order to make the sliding table well matched with the sliding table 623, the sliding table is matched with one side of the dovetail groove through the pad 625, the sliding table 623 can be better matched with the sliding table 623 through the thickness of the trimming pad, and the two sides of the pad 623 can be easily pressed against the dovetail groove 625 through the pad 625, and the fastener 625 can be easily fixed on the two sides of the dovetail groove 625.
In order to reduce the influence of deformation of the middle part of the pad 625 on the sliding of the slide 622 when the pad 625 is extruded by two sides, in an embodiment, a supporting block 626 is further arranged on the pad 625, the supporting block 626 is positioned in the middle of the pad 625, the supporting block 626 is abutted against the side wall of the dovetail groove through a spring, the middle part of the pad 625 is supported by installing the supporting block 626 at the middle part of the pad 625, the pad 625 cannot be deformed to influence the sliding of the slide 622 when two sides are extruded, meanwhile, a spring is further arranged between the supporting block 626 and the dovetail groove, the spring is abutted against the side wall of the dovetail groove, when the slide 622 vibrates in the sliding process, a part of vibration can be counteracted through the spring, and the abrasion caused by the vibration to the dovetail groove and the sliding table is reduced.
In order to better polish the magnetic steel, in an embodiment, the polishing mechanism 3 comprises a polishing head 31, a servo motor 32, a transmission shaft 33, a supporting plate 34 and a plurality of supporting rods 35, wherein the servo motor 32 is installed on the top surface of the supporting plate 34, the plurality of supporting rods 35 are circumferentially arranged along the bottom surface of the supporting plate 34, the number of the supporting rods 35 is at least 4, the supporting rods are respectively installed at four corners of the supporting plate 34, the supporting plate 34 is connected with the top surface of a sliding block 622 through the supporting rods 35, the transmission shaft 33 penetrates through two opposite side surfaces of the sliding block 622 and is rotationally connected with the sliding block 622, two ends of the transmission shaft 33 are respectively connected with the servo motor 32 and the polishing head 31, the servo motor 32 is in communication connection with the detection mechanism 7, a conveying belt is usually adopted for connection when the servo motor 32 is connected with the transmission shaft 33, and the degree of the conveying belt can be adjusted by adjusting the distance supported by the supporting rods 35, so that the servo motor 32 can be better made to rotate with the transmission shaft 33 to finish polishing.
Meanwhile, since the servo motor 32 can generate vibration during the starting process, if the servo motor 32 is directly mounted on the top surface of the slider 622, the contact surface between the servo motor 32 and the slider 622 is larger, the larger the contact area between the vibration source and other objects is, the more obvious the generated resonance effect is, so that when the servo motor 32 is started, the generated vibration can be directly transmitted to the slider 622, and the vibration can influence the sliding effect of the slider 622 during sliding. In order to reduce the vibration of the servo motor 32 to make the slider 622 generate resonance to affect the sliding effect of the slider 622 and the polishing effect of the polishing head 31, the support rod 35 is used for connecting with the slider 622 to reduce the supporting area to reduce the resonance, and the rotation speed of the servo motor 32 is adjustable, so that the polishing effect of the polishing head 31 can be changed by directly changing the rotation speed when the detection signal transmitted by the detection mechanism 7 is received, the polishing effect of the polishing head 31 can reach +/-0.01 mm degree through the structure, and the process of adjusting the machine can be more convenient and rapid.
