DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] A fully automatic surface grinder, such as Figure 1 and Figure 2, including a bed 1, and a movable platform 11 that moves along the XY direction is provided on one side of the bed 1. Moving along the XY direction means that the movable platform 11 can move along the X-axis and Y-axis directions respectively. This type of movable platform 11 is very common on grinding machines, so the specific structure is not described in detail. A rotating plate 12 is rotatably provided on the upper end surface of the movable platform 11, and an electromagnetic suction cup 13 is provided on the upper end surface of the rotating plate 12. A driving member for driving the rotating plate 12 to rotate is provided on the movable platform 11.

[0022] like Figure 1 and Figure 2 After the electromagnetic chuck 13 is installed on the rotating plate 12, the driving component can change the position of the electromagnetic chuck 13 on the moving platform 11 to make it swing. When the workpiece is manually placed on the electromagnetic chuck 13, if the workpiece is deviated, the driving component can adjust the position of the electromagnetic chuck 13, and then adjust the position of the workpiece, so as to achieve the purpose of correcting the workpiece after placing the workpiece on the electromagnetic chuck 13, thereby improving the automation of the grinder.

[0023] like Figure 1 and Figure 2 The upper end surface of the mobile platform 11 is detachably connected to the fixed base plate 14 through bolts 143, and a rotating column 141 is provided on one side of the upper end surface of the fixed base plate 14. At this time, the rotating plate 12 is placed on the fixed base plate 14, and the rotating plate 12 is rotatably connected to the fixed base plate 14 through the rotating column 141. There are several bolts 143 distributed in a straight line with the rotating column 141 and are distributed on one side of the rotating column 141. A waist-shaped groove 144 for placing each bolt 143 is opened on the upper end surface of the rotating plate 12. When the rotating plate 12 rotates around the rotating column 141, each bolt 143 moves in the waist-shaped groove 144 to reduce the influence of each bolt 143 on the rotation of the rotating plate 12.

[0024] like Figure 6 and Figure 7 and Figure 8 The driving member includes an L-shaped driving plate 121 disposed on a vertical surface of the rotating plate 12 away from the rotating column 141, the vertical surface of the driving plate 121 is connected to the vertical surface of the rotating plate 12 by a plurality of locking screws, and the horizontal surface is placed on the upper end surface of the fixed bottom plate 14; like Figure 6 and Figure 7 and Figure 8, the upper end surface of the fixed bottom plate 14 is provided with vertical upright plates 145 on the left and right sides of the driving plate 121, the upper end surfaces of the two upright plates 145 are connected by a horizontal plate 146, and a slider 1461 is slidably connected to the horizontal plate 146, and the sliding direction of the slider 1461 is perpendicular to the plate surface of the upright plate 145, and a threaded rod 1462 is rotatably connected between the two upright plates 145, and the threaded rod 1462 passes through the slider 1461 and is threadedly connected to the slider 1461, and a driving motor 1463 for driving the threaded rod 1462 to rotate is provided on one of the upright plates 145; the driving motor 1463 drives the threaded rod 1462 to rotate, which can drive the slider 1461 to slide on the horizontal plate 146, and at this time, there is a gap between the lower end surface of the slider 1461 and the horizontal plane of the driving plate 121.

[0025] like Figure 6 and Figure 7 and Figure 8 The roller 122 is rotatably connected to the horizontal plane of the driving plate 121, and a through groove 1464 for the roller 122 to slide is provided on the lower end surface of the slider 1461, and the length direction of the through groove 1464 is perpendicular to the sliding direction of the slider 1461; like Figure 6 and Figure 7 and Figure 8 The upper end surface of the fixed base plate 14 is provided with vertical support rods 147 on the left and right sides of the driving plate 121. The upper ends of the support rods 147 are connected by a horizontal plate 1471. A cylinder 1472 is provided on the horizontal plate 1471. A pressure block 1473 is provided on the piston rod of the cylinder 1472. The pressure block 1473 is located above the horizontal plane of the driving plate 121.

[0026] like Figure 6 and Figure 7 and Figure 8 , the working principle of the driving part: the driving motor 1463 drives the threaded rod 1462 to rotate, so that the slider 1461 slides on the horizontal plate 146, and at this time the through groove 1464 on the slider 1461 drives the roller 122 to slide in the through groove 1464, that is, when the threaded rod 1462 moves forward and backward with the slider 1461, that is, moves along the Y-axis direction, the roller 122 moves left and right in the through groove 1464, and then drives the rotating plate 12 to swing around the rotating column 141 through the driving plate 121. The setting of the roller 122 reduces the friction between the roller 122 and the groove wall of the through groove 1464 when the roller 122 moves in the through groove 1464, thereby facilitating the movement of the roller 122; the driving motor 1463 is a servo motor, and the driving motor 1463 drives the threaded rod 1462 to rotate, converting the linear motion into angular motion for deviation correction.

[0027] like Figure 6 and Figure 7 and Figure 8When the rotating plate 12 rotates to a suitable position, the piston rod of the cylinder 1472 moves downward, and then presses the pressing block 1473 on the horizontal plane of the driving plate 121, fixing the position of the driving plate 121, so that the position of the rotating plate 12 is also fixed, and the position of the workpiece is also fixed, which is convenient for workpiece processing. Therefore, the cylinder 1472 drives the pressing block 1473 to lift up before the rotating plate 12 corrects the workpiece. After the correction is completed, that is, the rotating plate 12 rotates to a suitable position, the pressing block 1473 presses down tightly.

[0028] like Figure 6 and Figure 7 and Figure 8 , the rotating connection between the rotating plate 12 and the rotating column 141 is rotatably connected by the bearing 142 arranged on the outer wall of the rotating column 141, specifically, the inner ring of the bearing 142 is sleeved on the outer wall of the rotating column 141, and the outer ring of the bearing 142 is installed in the installation hole opened in the rotating plate 12. At this time, the specific installation process is to first place the rotating plate 12 on the fixed bottom plate 14, at this time the rotating column 141 is in the installation hole, and then put the bearing 142 into the installation hole. The worker needs to knock the bearing 142 into the installation hole so that the outer wall of the upper end of the rotating column 141 enters the inner ring of the bearing 142, and the outer ring of the bearing 142 enters the installation hole, thereby realizing the rotating connection between the rotating plate 12 and the rotating column 141; like Figure 7 and Fig. 9 and Fig.10 In the above installation process, since the bearing 142 needs to be knocked into the installation hole, a small gap exists between the rotating plate 12 and the fixed bottom plate 14. The fixed bottom plate 14 is provided with a clamping member for reducing the gap between the fixed bottom plate 14 and the rotating plate 12. At this time, the setting of the clamping member reduces the gap between the fixed bottom plate 14 and the rotating plate 12, so that the plate surfaces of the fixed bottom plate 14 and the rotating plate 12 are more closely fitted, thereby reducing the error during workpiece processing.

[0029] like Figure 7 and Fig. 9 and Fig.10 The pressing member includes a plurality of waist-shaped card slots 148 opened on the lower end surface of the fixed bottom plate 14, and the lower end surface of the fixed bottom plate 14 is provided with waist-shaped card slots 149 penetrating the fixed bottom plate 14 at the middle position of each waist-shaped card slot 148; like Figure 7 and Fig. 9 and Fig.10The upper end surface of the rotating plate 12 is provided with waist-shaped card slots 3 123 corresponding to each waist-shaped card slot 1 148, and the upper end surface of the rotating plate 12 is provided with waist-shaped card slots 4 124 penetrating the rotating plate 12 at the middle position of each waist-shaped card slot 3 123, and each waist-shaped card slot 4 124 is distributed and connected with each waist-shaped card slot 2 149 one by one, and a tension spring 1491 is placed in the connected space, and the upper and lower ends of the tension spring 1491 are fixed with connecting plates 1492, and each connecting plate 1492 is provided with a threaded hole; like Figure 7 and Fig. 9 and Fig.10 A clamping plate 1493 is placed in each of the waist-shaped slot 148 and the waist-shaped slot 3 123. Each clamping plate 1493 spans across the waist-shaped slot 2 149 or the waist-shaped slot 4 124. Each clamping plate 1493 is threadedly connected with a fastening screw 1494. One end of each fastening screw 1494 away from the clamping plate 1493 is threadedly connected to the threaded holes on the upper and lower connecting plates respectively. During installation, first put the clamping plate 1493 on the fixed base plate 14 into the waist-shaped clamping groove 148, then tighten the screw 1494 through the clamping plate 1493 and thread it with the threaded hole on the connecting plate 1492 at the lower end of the tension spring 1491, thereby fixing the lower end of the tension spring 1491, and then after the rotating plate 12 is rotatably connected to the rotating column 141, the worker puts the clamping plate 1493 in the waist-shaped clamping groove 3 123, and then tightens the screw 1494 through the clamping plate 1493 and thread it with the threaded hole of the connecting plate 1492 at the upper end of the tension spring 1491. At this time, the tension spring 1491 is stretched, so that the clamping plate 1493 in the waist-shaped clamping groove 3 123 produces a downward squeezing force on the rotating plate 12, thereby reducing the gap between the rotating plate 12 and the fixed base plate 14, facilitating the processing of the workpiece, improving efficiency, saving costs, and reducing risks.

[0030] like Figure 7 and Fig. 9 and Fig.10 The number of the waist-shaped slots 148 is set to four, and the distribution position connection line is a rectangle, wherein two waist-shaped slots 148 are distributed close to the rotating column 141.

[0031] like Figure 3 and Figure 4 and Figure 5 When the workpiece is processed, it is necessary to take the workpiece off the electromagnetic chuck 13. At this time, a plurality of ejection holes 131 are provided on the upper end surface of the electromagnetic chuck 13. Each ejection hole 131 is slidably connected with an ejection rod 132. Each ejection hole 131 is distributed close to the side of the electromagnetic chuck 13. A connecting hole 133 connected to the lower end of the ejection hole 131 is provided on the side of the electromagnetic chuck 13. An ejection member for driving the upper end of the ejection rod 132 to slide out of the orifice of the ejection hole 131 is provided on the side of the electromagnetic chuck 13.

[0032] like Figure 3 and Figure 4 and Figure 5 The ejector includes a cylinder 134 arranged on the side of the electromagnetic suction cup 13, a push block 135 is arranged on the piston rod of the cylinder 134, a fixed block 136 is arranged on the side wall of the electromagnetic suction cup 13, and a slideway for the push block 135 to slide is provided on the fixed block 136. At this time, one side of the push block 135 is in contact with the side of the electromagnetic suction cup 13, and an extension rod extending out of the opening of the connecting hole 133 is provided at the lower end of the ejector rod 132. The extension rod is horizontally distributed and a roller 137 is provided at one end extending out of the opening of the connecting hole 133. One end of the extension rod extends out of the opening of the connecting hole 133 and also extends out of the side of the electromagnetic suction cup 13. An inclined groove 138 for the roller 137 to slide is provided on the push block 135, and the higher end of the inclined groove 138 is distributed close to the cylinder 134.

[0033] like Figure 3 and Figure 4 and Figure 5 , the working principle of the ejector: the piston rod of the second cylinder 134 drives the push block 135 to slide on the fixed block 136, and at this time, the roller 137 slides along the inclined groove 138. When it moves to the end of the inclined groove 138 with a higher height, the upper end of the ejector rod 132 moves out of the upper end hole wall of the ejector hole 131, thereby facilitating the workpiece to be pushed away from the electromagnetic suction cup 13, and facilitating the workpiece to be removed from the electromagnetic suction cup 13, and then the piston rod of the second cylinder 134 drives the push block 135 to slide in the opposite direction, so that the roller 137 slides along the inclined groove 138 to the side of the inclined groove 138 with a lower height, so that the ejector rod 132 gradually enters the ejector hole 131 until the upper end of the ejector rod 132 completely enters the ejector hole 131.

[0034] like Figure 1 The rotating plate 12 is provided with an L-shaped support plate 15, and the horizontal portion of the support plate 15 is provided with a protective cover 151 covering the outer wall of the cylinder 2 134 and the fixing block 136. The setting of the protective cover 151 protects the cylinder 2 134.

[0035] like Figure 3 and Figure 4, a padding plate 19 is provided on the upper end surface of the rotating plate 12, and the setting of the padding plate 19 is convenient to meet the processing requirements. The electromagnetic chuck 13 is placed on the padding plate 19 and fixed by a fixing part. The fixing part includes two clamping blocks 191 located on the left and right sides of the electromagnetic chuck 13, that is, there are two clamping blocks 191 on one side of the electromagnetic chuck 13, and the lower end surface of the clamping block 191 is provided with three step surfaces from bottom to top, the lowermost step surface is in contact with the upper end surface of the padding plate 19, and the uppermost step surface is in contact with the upper end surface of the side boss of the electromagnetic chuck 13. There is a gap between the middle step surface and the padding plate 19, and the upper end surface of each clamping block 191 is penetrated with a positioning screw 192, and the positioning screw 192 passes through the clamping block 191 and the padding plate 19 and is threadedly connected to the rotating plate 12. At this time, the clamping block 191 is pressed on the boss of the electromagnetic chuck 13 by each positioning screw 192, and then the electromagnetic chuck 13 is fixed on the padding plate 19.

[0036] like Figure 1 and Figure 2 The bed 1 is provided with a column 16 on one side of the movable platform 11, and a grinding wheel 161 slidingly connected to the column 16 is slidably connected along the Z-axis direction; there are various driving modes for the movement of the grinding wheel 161 on the column 16, including but not limited to the following structure, which is not drawn in the figure: the specific sliding mode can be that a groove 1 along the height direction of the column 16 is opened on the column 16, a Z-axis screw rod is rotatably connected in the groove 1, and a motor 1 for driving the Z-axis screw rod to rotate is provided on the column 16, a slide plate 1 is slidably connected in the groove 1, the Z-axis screw rod passes through the slide plate 1 and is threadedly connected to the slide plate 1, the grinding wheel 161 is rotatably connected to the slide plate 1, and a motor 2 for driving the grinding wheel 161 to rotate is provided on the slide plate 1; the motor 1 drives the Z-axis screw rod to rotate, driving the slide plate to move up and down in the Z-axis direction, so as to facilitate the descent and ascent of the grinding wheel 161.

[0037] like Figure 1 and Figure 2 The upper end surface of the bed 1 is slidably connected to a movable plate 17 that slides along the Y-axis direction. The movable plate 17 is a U-shaped plate with an opening toward the column 16, so that when the movable plate 17 moves along the Y-axis, the column 16 is in the opening of the movable plate 17, reducing the influence of the column 16 on the movement of the movable plate 17; there are many driving modes for the movable plate 17 to move on the bed 1, including but not limited to the following structure, which is not drawn in the figure: the upper end surface of the bed 1 is provided below the movable plate 17 There is a support seat, and a long strip groove 2 is opened on the lower end surface of the moving plate 17. When the moving plate 17 moves along the Y-axis direction, the support seat moves in the long strip groove 2 to reduce the influence of the support seat on the movement of the moving plate 17. The long strip groove 2 is rotatably connected with a Y-axis screw rod between the groove wall on the side facing the support seat and the support seat. The two ends of the Y-axis screw rod respectively pass through the support seat and the side of the moving plate 17 away from the column 16 and are driven to rotate by a motor 3 arranged on the side of the moving plate 17 away from the column 16; like Figure 1 and Figure 2 Motor 3 drives the Y-axis screw to rotate.
