DETAILED DESCRIPTION

[0020] Embodiment 1, as Figures 1 to 5 As shown, an efficient metal workpiece grinding tool comprises a guide rod 1, which is fixedly mounted on a movable base 4 which can reciprocate along the axis direction of the grinder, a support plate 2 for ejecting and unloading the ground hexagonal nuts is arranged on the outer side of the guide rod 1, and adjustment components 5 are arranged on both sides of the support plate 2; a correction plate 3 for correcting the angle of the hexagonal nut is rotatably matched inside the support plate 2, a groove in the shape of the hexagonal nut is provided inside the correction plate 3, and a transmission component 6 is arranged between the guide rod 1 and the correction plate 3; a support plate 8 is slidably arranged in the groove, and an ejection component 7 is arranged at the bottom of the correction plate 3.

[0021] A grinding mechanism 13 is arranged at the top of the other end of the grinder, and the grinding mechanism 13 is installed on the mounting frame of the grinder. The grinding mechanism 13 includes two groups of symmetrically arranged grinding components, and the two groups of grinding components are installed at the bottom end of the rotating disc. A rotating motor is arranged at the top end of the rotating disc, and the output end of the rotating motor is connected to the rotating disc.

[0022] When the guide rod 1 is moved, the support plate 2 and the guide plate 3 are moved together, and the support plate 2 is adjusted by the adjusting component 5 to move up and down. When the support plate 2 is moved, the adjustment component 5 adjusts the support plate 2 to move up and down. When the support plate 2 is lowered, the cross-sectional shape of the top of the guide rod 1 is set to be a triangle, and the support plate 2 is lowered to allow the hexagonal nut to be sleeved on the outside of the guide rod 1. At this time, the friction between the thread on the inner wall of the hexagonal nut and the guide rod 1 is greater than the friction between the bottom end of the hexagonal nut and the top end of the guide plate 3. Therefore, when the guide plate 3 is driven to rotate 360 ​​degrees by the cooperation of the transmission component 6, there is a difference in the rotation speed of the hexagonal nut and the guide plate 3. Until the bottom end of the regular hexagonal nut is aligned with the groove of the regular hexagonal nut, the regular hexagonal nut just falls into the groove, and the groove is reset when it rotates 360 degrees, and the regular hexagonal nut is driven to have the same angle as the initial groove, so that the angle correction of the regular hexagonal nut is completed. Through the setting of the support plate 2 and the correction plate 3, combined with the cooperation of the adjustment component 5 and the transmission component 6, the correction plate 3 is driven to rotate 360 ​​degrees, and the regular hexagonal nut placed at any angle is corrected to the preset angle, ensuring that the contact angle of the grinding wheel or the grinding tool with the surface of the regular hexagonal nut during the grinding process is consistent, thereby improving the accuracy and consistency of the grinding, helping to reduce the surface roughness after grinding, making the surface of the regular hexagonal nut smoother and more uniform, improving the stability during the grinding process, reducing safety risks, and correcting the angle of the regular hexagonal nut without using an angle measuring tool, which is simple and efficient; When the correcting plate 3 rotates and then descends vertically, the supporting plate 8 is lifted up by the ejection assembly 7, so that the top of the supporting plate 8 is higher than the top of the correcting plate 3, and the supporting plate 8 is smaller than the end face size of the regular hexagonal nut, and the regular hexagonal nut is completely ejected from the groove. At this time, the regular hexagonal nut is exactly located between the two sets of grinding assemblies, and the two parallel sides of the regular hexagonal nut are exactly parallel to the grinding heads in the two sets of grinding assemblies. At this time, the second electric push rod on the grinding assembly can be started to drive the grinding head to move toward the two sides of the regular hexagonal nut. After fixing the two parallel sides of the regular hexagonal nut, start the motor connected to the grinding head, and drive the grinding head to rotate by the motor to grind the two sides of the regular hexagonal nut. After the grinding of both sides of the regular hexagonal nut is completed, pause the motor first The grinding head is driven to move away from the regular hexagonal nut by the second electric push rod, and then the rotating motor on the mounting frame is started to drive the rotating disc to rotate by the rotating motor, thereby driving the two sets of grinding components to rotate 60 degrees to grind the other two sides, according to the above working principle, until the six side walls of the regular hexagonal nut are ground, at this time, the movable base 4 can be driven by the first electric push rod to move away from the grinding mechanism 13, so that the ground regular hexagonal nut is reset. During the resetting process of the regular hexagonal nut, the support plate 2 and the correcting plate 3 are moved upward by the cooperation of the adjusting component 5 and the transmission component 6. The upward movement of the support plate 2 and the correcting plate 3 drives the regular hexagonal nut to move upward at the same time, so that the regular hexagonal nut can be ejected and unloading is convenient.

[0023] As a specific structure of this embodiment, the adjustment component 5 includes two symmetrically arranged vertical plates 501, and the two vertical plates 501 are fixedly installed on the top of the grinder. A first sliding groove 502 is opened on the side where the two vertical plates 501 are close to each other, and a pull rod 503 is fixedly connected to both sides of the support plate 2. The end of the pull rod 503 away from the support plate 2 is arranged in the first sliding groove 502 and slidably cooperates with it.

[0024] The transmission assembly 6 includes a second slide groove 601, both ends of which are arranged as first straight grooves, and a first spiral groove is arranged between the two straight grooves; a first slider 602 is fixedly connected to the inside of the deviation correction plate 3, and one end of the first slider 602 is arranged in the second slide groove 601 and slides with it.

[0025] The ejection assembly 7 includes two symmetrically arranged ejection rods 701 , both of which are fixedly mounted on the top of the movable base 4 , and the bottom of the deflection-correcting plate 3 is provided with two through holes 702 matched with the ejection rods 701 .

[0026] In this embodiment, when the first electric push rod drives the movable base 4 to move toward the grinding mechanism 13, the movable base 4 moves to drive the guide rod 1 and the support plate 2 to move, and the support plate 2 moves to drive the pull rod 503 to slide in the vertical plate 501, and then the pull rod 503 moves from the high position to the low position of the first slide groove 502, which means that the pull rod 503 drives the support plate 2 to descend, and the descent of the support plate 2 drives the correction plate 3 to descend, and the descent of the correction plate 3 drives the first slider 602 to slide in the first section of the first straight groove until the first slider 602 slides to the first spiral groove position, at which time the correction plate 3 rotates 360 degrees to correct the angle of the hexagonal nut; After the regular hexagonal nut falls into the groove, the first slider 602 slides to the tail section of the first straight groove, and the support plate 2 and the correcting plate 3 both move vertically downward until the end of the pull rod 503 moves to the lowest point of the first slide groove 502. When the pull rod 503 moves to the lowest point of the first slide groove 502, the bottom end of the support plate 2 contacts the top of the moving base 4, and the ejector rod 701 at the top of the moving base 4 passes through the through hole 702 to lift the support plate 8 located in the correcting plate 3, so that the regular hexagonal nut is completely exposed; At this time, the first electric push rod continues to move toward the grinding mechanism 13, and the pull rod 503 is always located in the lowest horizontal section of the first slide groove 502, thereby keeping the support plate 2, that is, the regular hexagonal nut, stationary.

[0027] Embodiment 2, as Figures 6 to 9 As shown, the interior of the guide rod 1 is hollow; three fixing blocks 9 for fixing regular hexagonal bolts are slidably arranged in an annular distribution inside the guide rod 1, and the fixing blocks 9 are arranged at the tail section of the first straight groove. Both ends of the fixing blocks 9 facing the inside of the guide rod 1 are arranged as arc surfaces, and the end of the fixing blocks 9 away from the guide rod 1 is the same smooth arc surface as the surface of the guide rod 1; an extrusion block 12 is arranged above the three fixing blocks 9, and the extrusion block 12 is slidably connected to the inside of the guide rod 1, and the extrusion block 12 is threadedly connected to the outside of the threaded rod 11, and the threaded rod 11 is rotatably connected to the top of the inner wall of the guide rod 1, and a driving assembly 10 is arranged in the threaded rod 11.

[0028] In this embodiment, the support plate 2 moves downward, driving the pull rod 503 to move downward. The pull rod 503 moves downward and drives the extrusion block 12 to move downward through the rotation of the driving threaded rod 11 of the driving assembly 10. The side of the extrusion block 12 close to the three fixed blocks 9 is set to an arc surface. Therefore, the movement of the extrusion block 12 can squeeze the three fixed blocks 9 to move away from the inside of the guide rod 1, thereby fixing the regular hexagonal nut after angle correction. The fixed regular hexagonal nut is under the feeding action of the first electric push rod, between the two sets of grinding assemblies, through the cooperation of the adjustment assembly 5, the transmission assembly 6, and the driving assembly 10 to drive the threaded rod 11 to rotate, thereby driving the extrusion block 12 to move downward and squeeze the three fixed blocks 9 to extend and fix the regular hexagonal nut, thereby preventing the regular hexagonal nut from deflecting at an angle during the grinding process, and further improving the accuracy of the angle correction of the regular hexagonal nut and the stability of grinding.

[0029] The specific structure of this embodiment is that the end of the guide rod 1 facing the movable base 4 is in a fully open state, and strip grooves are provided on both sides of the movable base 4, which are connected to the inside of the guide rod 1; the driving component 10 includes a sliding rod 1002, and the sliding rod 1002 is arranged inside the threaded rod 11, and the end of the sliding rod 1002 away from the guide rod 1 is fixedly connected with a connecting rod 1001, and the connecting rod 1001 is arranged in the strip groove and fixed with the pull rod 503; the outer wall of the sliding rod 1002 is fixedly connected with a second sliding block 1003, and the inner wall of the threaded rod 11 is provided with a third sliding groove 1004, and the second sliding block 1003 is arranged in the third sliding groove 1004 and slidably cooperates with it.

[0030] Both ends of the second sliding block 1003 are composed of two sections of second straight grooves, and a section of second spiral groove is arranged in the middle of the two sections of second straight grooves.

[0031] In this embodiment, the support plate 2 descends and drives the pull rod 503 to descend, the pull rod 503 descends and drives the connecting rod 1001 to descend, the connecting rod 1001 descends and drives the sliding rod 1002 to descend, and the sliding rod 1002 descends and drives the second slider 1003 to slide in the third slide groove 1004. Before the right hexagonal nut angle is corrected, the second slider 1003 is located at the first end of the third slide groove 1004 and slides in the second straight groove until the right hexagonal nut angle is corrected. At this time, the first slider 602 just moves to the first straight groove. At the tail section of the groove, the second slider 1003 slides into the second spiral groove, and the second slider 1003 drives the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the extrusion block 12 to move downward, and then the three fixing blocks 9 are squeezed out to fix the regular hexagonal nut. The regular hexagonal nut is separated from the support plate 2. After the regular hexagonal nut is fixed by the fixing block 9, the second slider 1003 moves with the pull rod 503 to slide into the second straight groove of the tail section of the third slide groove 1004, and the threaded rod 11 stops rotating. When the first electric push rod drives the movable base 4 to reset, it also drives the support plate 2 to move upward, and drives the threaded rod 11 to reverse, driving the extrusion block 12 to reset. At this time, the support plate 2 contacts the regular hexagonal nut and the regular hexagonal nut is pushed out through the support plate 2.
