DETAILED DESCRIPTION
[0030] See also Figure 1-3In an embodiment of the present invention, a deburring and grinding machine for aluminum parts comprises a workbench 1, the upper end of the workbench 1 is rotatably connected to a turntable 7, the upper end of the turntable 7 is provided with a fixing mechanism for clamping and fixing the aluminum parts, a base 2 is slidably connected to the middle part of one side of the workbench 1, a positioning plate 15 is slidably connected to the middle part of the upper end of the base 2, and a grinding mechanism for deburring the aluminum parts is provided on the upper end of the positioning plate 15, a driving motor 3 is transmission-connected to one side of the lower end of the workbench 1, and a reciprocating screw 4 is transmission-connected to the output end of the driving motor 3 (the screw is driven to rotate by the motor, and the nut reciprocates along the axial direction under the drive of the thread. This movement mode enables the reciprocating screw to make the slider reciprocate without changing the rotation direction of the main shaft), the base 2 is transmission-connected to the reciprocating screw 4, and a steering assembly for driving the turntable 7 to rotate is provided at the lower part of the inner cavity of the workbench 1. When the base 2 moves horizontally to one side of the reciprocating screw 4, the turntable 7 rotates 90° counterclockwise.
[0031] The grinding mechanism includes a mounting plate 5, the upper end of the positioning plate 15 is fixedly connected to the mounting plate 5 on the side away from the workbench 1, the upper part of the mounting plate 5 is connected to the side close to the workbench 1, and the output end of the servo motor 6 is fixedly connected to the grinding block, and the middle part of the upper end of the turntable 7 is fixedly connected to the placement table 8, and the plane where the upper end of the placement table 8 is located coincides with the plane where the center position of the grinding block is located, and the upper end of the turntable 7 is provided with a symmetrical slide groove 10, and the fixing mechanism includes a symmetrical clamping plate 9, and the lower end of the clamping plate 9 is fixedly connected to a slider on the side close to the placement table 8 11, the outer wall of the slider 11 is slidably matched with the inner cavity side wall of the slide groove 10, and the lower end of the turntable 7 is externally rotatably connected with the upper and lower groups of first gears 37. The first racks 16 are centrally symmetrical about the center of the placement table 8 on both sides of the first gear 37. The first gear 37 and the first rack 16 are meshed with each other. The upper and lower groups of first gears 37 and the first rack 16 are only different in height. The first rack 16 is slidably connected to the inner cavity side wall of the turntable 7, and the end of the first rack 16 away from the first rack 37 is fixedly connected to the side close to the placement table 8 There is an extension rod 17, and the middle part of one end of the extension rod 17 away from the first rack 16 is vertically slidably connected to the outer wall of the slider 11. The outer wall of the slider 11 is directly elastically connected to the upper end surface of the extension rod 17 through a spring, that is, when the extension rod 17 moves horizontally, it will drive the slider 11 to move horizontally synchronously, thereby driving the clamping plate 9 to move horizontally. When the slider 11 receives a vertical downward force, it will move downward along the middle part of the extension rod 17, and reset due to the elastic force when the force is lost. The upper and lower sets of first racks 16 are both away from the side of the extension rod 17. The transmission is connected with an electric telescopic push rod, that is, the single first rack 16 is driven to move in the horizontal direction through the electric telescopic push rod, and the first gear 37 and another first rack 16 in the same plane are moved synchronously, so as to simultaneously drive the symmetrical clamping plates 9 away from or close to the position of the placement table 8. When fixing the aluminum part, it is first placed on the upper end surface of the placement table 8, and then the upper and lower groups of first racks 16 are driven to approach the position of the placement table 8, and the symmetrical clamping plates 9 are used to approach the outer wall of the aluminum part, thereby centering and clamping the aluminum part.
[0032] See also Figure 4 , Fig. 9 and Fig.11The end of the positioning plate 15 close to the workbench 1 is fixedly connected with a driving rod 20, and the driving rod 20 moves in the horizontal direction with the positioning plate 15. A horizontal groove 14 is provided on one side of the workbench 1 close to the positioning plate 15, and the horizontal groove 14 is slidably matched with the outer wall of the positioning plate 15. A positioning rod 34 is slidably connected to the middle part of the inner cavity of the horizontal groove 14, and the outer part of the positioning rod 34 is slidably connected to the middle part of the inner cavity of the positioning plate 15, that is, when the positioning rod 34 moves in the inner cavity of the horizontal groove 14 toward the direction of the placement table 8, it will drive the positioning plate 15 to synchronously approach the position of the placement table 8. When the positioning plate 15 moves horizontally with the base 2, the position of the positioning rod 34 remains stationary, and the side of the positioning rod 34 away from the positioning plate 15 is elastically connected to the side wall of the inner cavity of the horizontal groove 14 through a spring. The lower end of the splint 9 is fixedly connected to the side away from the slider 11 with a connecting rod 18, and the middle part of the side of the connecting rod 18 away from the slider 11 is fixedly connected to the driving plate 19, and a connecting rod 18 is provided below the slide groove 10 with a driving plate When the driving plate 19 moves downward, the connecting rod 18 drives the clamping plate 9 and the sliding block 11 to move downward. During the grinding of the aluminum part, after the aluminum part to be ground is clamped and fixed by the clamping plate 9, the positioning rod 34, under the action of elastic force, the side close to the placing table 8 will fit with the side of the driving plate 19 away from the sliding block 11, thereby driving the positioning plate 15 to approach the position of the driving plate 19, and then driving the grinding block to approach the position of the clamping plate 9 through the movement of the positioning plate 15. At this time, the outer wall of the grinding block can be automatically made to fit closely with the outer wall of the aluminum part to be ground. At this time, the driving motor 3 and the reciprocating screw rod 4 drive the base 2 to drive the grinding block to move horizontally, and the servo motor 6 drives the grinding block to rotate, so that the grinding process of one side of the aluminum part can be completed.
[0033] See also Figure 5 and Figure 6However, in the process of horizontal movement of the grinding block to deburr the aluminum part, the outer wall of the grinding block gradually approaches the outer wall of the clamping plate 9. In order to avoid the clamping plate 9 from touching the grinding block, a driving rod 20 is fixedly connected to the middle of one end of the positioning plate 15 close to the placing table 8. Both ends of the driving rod 20 are provided with inclined surfaces 36. A positioning groove 22 is provided on the side of the driving plate 19 close to the positioning plate 15. The lower parts of the inner cavity of the positioning groove 22 are provided with inclined edges 21. The lower end surface of the driving rod 20 coincides with the plane where the bottom of the inclined edge 21 is located. When the driving rod 20 is close to the driving plate 19, the inclined surface 36 and the inclined surface 36 are aligned. The bevel 36 and the bevel 21 will contact each other, and the bevel 36 and the bevel 21 will fit each other, so that during the horizontal movement of the driving rod 20, the bevel 36 will first contact the bevel 21. Since the height of the driving rod 20 remains fixed, the driving plate 19 will move downward relatively to the lower part of the inner cavity of the adaptation groove 26 until the driving rod 20 moves into the inner cavity of the positioning groove 22. At this time, the driving plate 19 drives the splint 9 to move downward through the connecting rod 18, so that the splint 9 is separated from the outer wall of the aluminum part, thereby avoiding the grinding block from touching the splint 9 during the grinding of the aluminum part. A T-slot 23 is provided in the upper part of the inner cavity of the positioning groove 22.
[0034] See also Figure 6The upper end of the driving rod 20 is elastically connected with a symmetrical T-block 24, and the outer wall of the T-block 24 is slidably matched with the inner cavity of the T-slot 23, that is, the T-block 24 that contacts the inner cavity side wall of the positioning groove 22 first will shrink into the inner cavity of the driving rod 20, and will not enter the inner cavity of the T-slot 23. Because when the inclined surface 36 drives the driving plate 19 to move downward by cooperating with the inclined edge 21, the T-block 24 that first approaches the positioning groove 22 and the T-slot 23 are not in the same horizontal plane. In the process of the driving plate 19 moving downward, the T-block 24 will directly contact the top of the inner cavity of the positioning groove 22 and shrink into the inner cavity of the driving rod 20, and then the T-block 24 close to the positioning groove 22 will horizontally enter the T-slot 23, and limit the position of the driving plate 19 in the vertical direction through the cooperation of the T-slot 23 and the T-block 24, so that only after the driving rod 20 is completely separated from the driving plate 19, the driving The movable plate 19 can be reset by elastic force. The length of the driving rod 20 is the same as that of the driving plate 19, and the lengths of both are greater than the length of the grinding block. That is, after the driving plate 19 moves down, the grinding block has not yet moved to the position of the clamping plate 9, and through the limiting effect of the cooperation of the T-slot 23 and the T-block 24, the clamping plate 9 will be reset after the grinding block is away from the position of the clamping plate 9, so that during the grinding process, when the grinding block is close to the clamping plate 9, the clamping plate 9 will automatically move down and away from the aluminum part, and after the grinding block grinds the position of the outer wall of the aluminum part corresponding to the clamping plate 9, the clamping plate 9 will be reset and clamp the outer wall of the aluminum part. Among the symmetrical clamping plates 9, only the clamping plate 9 close to the grinding block will move down, and the other three clamping plates 9 will continue to clamp and position the aluminum part during the grinding process of the aluminum part, so there is no need to worry about the aluminum part moving during the grinding process after a single clamping plate 9 moves down.
[0035] See also Figure 7 and Fig.10The outer wall of the turntable 7 is provided with an annular groove 25, the position of the annular groove 25 coincides with the positioning rod 34, the outer wall of the positioning rod 34 is slidably matched with the inner cavity side wall of the annular groove 25, the middle part of the lower end of the turntable 7 is fixedly connected with a rotating shaft 28, the lower end of the rotating shaft 28 is rotatably connected to the workbench 1, the outer wall of the rotating shaft 28 is fixedly connected with a second gear 29, the outer wall of the second gear 29 is provided with a shell 30 which is centrally symmetrical about the center position of the rotating shaft 28, the end of the shell 30 away from the rotating shaft 28 is fixedly connected with a fixing rod 27, and the end of the fixing rod 27 away from the shell 30 is fixed A driven plate 13 is connected, and the inner cavity of the workbench 1 is provided with a driven groove 12 that slides with the driven plate 13. The outer shell 30 and the fixed rod 27 are both slidably connected to the inner cavity of the workbench 1. A pushing block 35 is fixedly connected to the upper end of the base 2 close to the side of the placement table 8. The plane where the top of the pushing block 35 is located coincides with the plane where the top of the driven plate 13 is located. When the pushing block 35 moves with the base 2, the pushing block 35 will gradually approach and push the driven plate 13 on one side to move horizontally, thereby driving the fixed rod 27 and the outer shell 30 to move horizontally through the driven plate 13.
[0036] See also Figure 8A second rack 33 is provided on the side of the housing 30 close to the rotating shaft 28, and the second rack 33 is meshed with the second gear 29. A symmetrical connecting rod 31 is rotatably connected to the side of the second rack 33 away from the second gear 29. The side of the connecting rod 31 away from the second rack 33 is rotatably connected to the side of the inner cavity of the housing 30 away from the rotating shaft 28. A baffle 32 is closely arranged on the side of the connecting rod 31 away from the driven plate 13. When the housing 30 moves away from the center position of the rotating shaft 28 along with the driven plate 13, the connecting rod 31 is blocked by the baffle 32, so that the second rack 33 remains in a state of meshing with the second gear 29, thereby driving the second gear The wheel 29 drives the rotating shaft 28 to rotate 90° counterclockwise. When the shell 30 drives the second rack 33 to reset, the second rack 33 contacts the outer wall of the second gear 29. Since the side of the second rack 33 close to the driven plate 13 is elastically connected to the inner cavity side wall of the shell 30 through a spring, when the second rack 33 contacts the second gear 29 during the reset process, the second rack 33 will deflect toward the inner cavity of the shell 30 synchronously with the connecting rod 31. After the shell 30 is reset, the second rack 33 is reset under the action of the elastic force, and the second rack 33 will not drive the rotating shaft 29 again during the reset process of the shell 30. 8 rotates, so that the rotating shaft 28 will only rotate 90° counterclockwise once when the housing 30 moves toward the position of the driven groove 12, and during the rotation of the aluminum part, even if the length and width of the aluminum part are different, the positioning rod 34 will automatically fit with the outer wall of the driving plate 19 corresponding to the different lengths under the action of elastic force, thereby automatically controlling the position of the driving rod 20 and the positioning plate 15, thereby ensuring that the outer wall of the grinding block will always automatically fit with the edge of the rotated aluminum part, so that the other side of the aluminum part rotates to the direction of the base 2, and when the grinding block moves toward the direction of the driving motor 3, the clamping plate close to the grinding block is driven again. The plate 9 moves downward to complete the deburring and grinding of the side of the aluminum part. The distance between the symmetrical driven grooves 12 is greater than the diameter of the turntable 7. Therefore, the turntable 7 will rotate 90° counterclockwise after the grinding block completes the deburring and grinding of one side of the aluminum part. The driven plate 13 is pushed to move by the pushing block 35. After the grinding block completes the deburring and grinding of one side wall of the aluminum part, the aluminum part will rotate 90° counterclockwise. Through the horizontal reciprocating motion of the grinding block, the four side walls of the aluminum part can be polished in turn. There is no need to manually adjust the position of the aluminum part, nor is there any need to disassemble and fix the aluminum part multiple times, thereby completing the multilateral grinding of the aluminum part.
