Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] A fully automatic grinding machine for smoothing deformed parts, such as Figure 1 The worktable includes a workbench 1, a vertical plate 4 at the top of the workbench 1, and a grinding assembly for grinding workpieces on the vertical plate 4. The top of the workbench 1 is horizontally connected to a machining seat 5 for placing workpieces via a moving part. Two diamond grinding bowls 49 for grinding the grinding wheel in the grinding assembly are provided on one side of the machining seat 5 on the workbench 1.

[0028] like Figure 1 and Figure 2 and Figure 3 and Figure 4 The moving component includes a base 7 that slides horizontally towards or away from the vertical plate 4 and is connected to the top of the worktable 1. The top of the worktable 1 has a groove 8 located below the base 7, and a partition 9 is vertically mounted at the bottom of the groove 8. A first lead screw 10 is rotatably connected to one side of the partition 9, and the end of the first lead screw 10 away from the partition 9 is rotatably connected to the groove wall of the groove 8. A first motor 12 for driving the first lead screw 10 to rotate is mounted on the partition 9. A first push plate 13 located within the groove 8 is located at the bottom of the base 7. One end of the first lead screw 10 passes through the first push plate 13 and is threadedly connected to it. The base 7 moves back and forth on the worktable 1, and the top of the base 7 is horizontally connected via a sliding component. A sliding block 14 is slidably connected, and a processing seat 5 is set at the top of the sliding block 14. The sliding block 14 moves left and right on the base 7. The sliding component includes two slide rails 15 set at the top of the base 7. The sliding block 14 is horizontally slidably connected to the two slide rails 15. The bottom end of the sliding block 14 is provided with a second push plate 16 located between the two slide rails 15. The top of the base 7 is provided with two opposing side plates 17. A second lead screw 18 is rotatably connected between the two side plates 17. One end of the second lead screw 18 passes through the second push plate 16 and is threadedly connected to the second push plate 16. At this time, the second lead screw 18 is parallel to the slide rail 15. A second motor 19 for driving the second lead screw 18 to rotate is provided on one of the side plates 17.

[0029] like Figure 1 and Figure 2 and Figure 3 and Figure 4The first motor 12 drives the first lead screw 10 to rotate. Since one end of the first lead screw 10 passes through the first push plate 13 and is threadedly connected to the first push plate 13, when the first lead screw 10 rotates, it pushes the first push plate 13 to move the base 7 closer to or away from the vertical plate 4. At this time, the slide 14 and the machining seat 5 will move with the base 7. The second motor 19 drives the second lead screw 18 to rotate. Since one end of the second lead screw 18 passes through the second push plate 16 and is threadedly connected to the second push plate 16, when the second lead screw 18 rotates, it pushes the second push plate 16 to move the slide 14 left and right. At this time, the machining seat 5 moves with the slide 14. At this time, through the cooperation of the first motor 12, the first lead screw 10, the first push plate 13, the base 7, the slide 14, the second motor 19, the second lead screw 18, and the second push plate 16, the machining seat 5 can be moved closer to the grinding assembly. At the same time, adjusting the position of the machining seat 5 can adjust the grinding position of the grinding assembly on the workpiece. It is simple and convenient to use.

[0030] like Figure 2 and Figure 5 and Figure 6 The grinding assembly includes a sliding groove 25 vertically positioned on one side of the upright plate 4, and a sliding plate 26 vertically slidingly connected within the sliding groove 25. An extension plate 27 is horizontally positioned on the side of the sliding plate 26 near the machining base 5. A rotating groove 28 penetrating the sliding plate 26 is formed on the side of the extension plate 27 away from the sliding plate 26, and a rotating shaft 29 is rotatably connected within the rotating groove 28. A grinding wheel 30 for grinding the workpiece is detachably connected to the side of the rotating shaft 29 near the machining base 5. The sliding plate 26 is provided with a mechanism for driving the rotating shaft 29 to rotate. The grinding motor 31 is connected to the upper and lower sides of the sliding groove 25 by a third lead screw 32, one end of which passes through the sliding plate 26 and is threadedly connected to the sliding plate 26. The vertical plate 4 is provided with a third motor 33 for driving the third lead screw 32 to rotate. A sliding column 34 is vertically provided between the upper and lower sides of the sliding groove 25. The top of the sliding plate 26 is provided with a circular groove 35 for the bottom end of the sliding column 34 to pass through vertically. The sliding column 34 is parallel to the third lead screw 32 and is located on both sides of the rotating shaft 29.

[0031] like Figure 2 and Figure 5 and Figure 6When the machining seat 5 moves below the grinding wheel 30 and the workpiece on the machining seat 5 needs to be ground, simply turn on the grinding motor 31. The rotating shaft of the grinding motor 31 drives the grinding wheel 30 to rotate clockwise through the rotating shaft 29. Then turn on the third motor 33. The rotating shaft of the third motor 33 drives the third lead screw 32 to rotate. Since one end of the third lead screw 32 passes through the sliding plate 26 and is threadedly connected to the sliding plate 26, the rotation of the third lead screw 32 can drive the sliding plate 26 to move vertically. When the sliding plate 26 moves downward and the rotating grinding wheel 30 contacts the workpiece, the workpiece on the machining seat 5 can be ground by the clockwise rotating grinding wheel 30. The cooperation between the sliding column 34 and the circular groove 35 on the sliding plate 26 can improve the stability of the sliding plate 26 when it moves vertically.

[0032] like Figure 1 An L-shaped bracket 36 is provided on the side of the extension plate 27 away from the sliding plate 26. The bracket 36 is provided with a first nozzle 37 facing the bottom of the grinding wheel 30 and an air jet 38 facing the bottom of the grinding wheel 30. The two first nozzles 37 are used to spray cutting fluid onto the grinding wheel 30. The purpose of this arrangement is to connect the first nozzles 37 to the external cutting fluid pipeline and the air jet 38 to the external air pipe. When the grinding wheel 30 is working, the first nozzles 37 can spray cutting fluid onto the grinding wheel 30. After the workpiece is ground and removed, the top of the machining seat 5 can also be rinsed through the first nozzles 37. When installing the next workpiece to be ground, the air jet 38 is first blown onto the top of the machining seat 5 to blow off the residual cutting fluid on the top of the machining seat 5. Then the workpiece to be ground can be installed on the top of the machining seat 5. This reduces the situation where there is a layer of cutting fluid on the machining seat 5 and the workpiece is placed directly on it, causing the workpiece to float.

[0033] like Figure 1 and Figure 7 The machining seat 5 is located on the top left of the slide 14. The top right of the slide 14 is provided with a detection component for detecting the diameter and thickness of the grinding wheel 30. The detection component includes a column 39 that is vertically mounted on the top of the slide 14, and a U-shaped frame plate 40 is provided on the top of the column 39. The frame plate 40 is provided with a first sensor 41 for detecting the diameter of the grinding wheel 30 and a second sensor 58 for detecting the thickness of the grinding wheel 30. The purpose of this setting is that after the grinding wheel 30 has been used for a certain period of time, the diameter and thickness of the grinding wheel 30 can be detected by the first sensor 41 and the second sensor 58, so that the staff can understand whether the grinding wheel 30 needs to be replaced, or whether it needs to be repaired, or check the size of the repaired grinding wheel 30.

[0034] The first sensor 41 for detecting the diameter of the grinding wheel 30 is a light amplifier of model fs-n4ln, and the second sensor 58 for detecting the thickness of the grinding wheel 30 is an existing thickness detection sensor.

[0035] like Figure 1 and Figure 7 and Figure 8 The top of the slide 14 is provided with a fixed seat 42 located on one side of the column 39. A long strip groove 43 is horizontally provided along the length of the fixed seat 42 at its top. Two opposing sliders 44 are horizontally connected within the long strip groove 43. Each slider 44 has an inverted U-shaped frame 45 at its top, and a vertical plate 46 at its top. A rotating groove 47 is provided on the side of each vertical plate 46 that is close to each other. A column 48 is rotatably connected within each rotating groove 47. A diamond grinding bowl 49 is provided on the side of each column 48 that is close to each other. A mounting plate 50 is vertically provided on one side of the fixed seat 42, and a drive shaft 51 is rotatably connected to one side of the mounting plate 50. A drive shaft 51 is mounted on the drive shaft 51 along the drive shaft 59. A transmission groove 52 is provided along the length direction of the 1 column. Two circular holes 53 are coaxially opened on the two columns 48. The end of the transmission shaft 51 away from the mounting plate 50 passes through the two circular holes 53 coaxially. Transmission blocks 54 located in the transmission groove 52 are provided on the inner walls of the two circular holes 53. A rotary motor 55 for driving the transmission shaft 51 to rotate is provided on the mounting plate 50. A fourth lead screw 56 is rotatably connected between the opposite sides of the long strip groove 43. One end of the fourth lead screw 56 passes through two sliders 44 and is threadedly connected to the two sliders 44. The fourth lead screw 56 is provided with two threads with opposite directions. The two sliders 44 are threadedly connected to the two threads respectively. A fourth motor 57 for driving the fourth lead screw 56 to rotate is provided on the mounting plate 50.

[0036] like Figure 1 and Figure 7 and Figure 8 By moving the slide block 14, the fixed seat 42 is moved to the bottom of the grinding wheel 30. Then, the rotating shaft of the rotating motor 55 drives the transmission shaft 51 to rotate. At this time, the transmission shaft 51 will drive the two columns 48 to rotate through the cooperation of the transmission groove 52 and the transmission block 54. At this time, the diamond grinding bowl 49 will follow the column 48 to rotate. Then, the rotating shaft of the fourth motor 57 drives the fourth lead screw 56 to rotate. At this time, since one end of the fourth lead screw 56 passes through the two sliders 44 and is threaded to both sliders 44, and the fourth lead screw 56 has two threads with opposite directions, and the two sliders 44 are threaded to the two threads respectively, when the fourth lead screw 56 rotates, it can simultaneously drive the two sliders 44 to move closer or further away from each other. At this time, the frame 45, the vertical plate 46, the column 48 and the diamond grinding bowl 49 will follow the slider 44 to move.

[0037] When the two sliders 44 approach each other until the two diamond grinding cups 49 touch each other, the grinding wheel 30 moves downward until the rotating grinding wheel 30 contacts the rotating diamond grinding cup 49. The diamond grinding cup 49 and the grinding wheel 30 rotate in the same direction. At this time, the outer surface of the grinding wheel 30 can be ground and dressed through the two diamond grinding cups 49, reducing the need to remove the grinding wheel 30 for grinding and dressing due to the dulling of the outer surface of the grinding wheel 30.

[0038] Alternatively, after the grinding wheel 30 moves downward between the two diamond grinding cups 49, the four motors 57, the fourth lead screw 56, and the slider 44 work together to bring the two diamond grinding cups 49 closer together until the sides of the two diamond grinding cups 49 are in contact with the sidewall of the grinding wheel 30. At this point, the thickness of the grinding wheel 30 can be ground by the two diamond grinding cups 49 to meet the required size. After grinding, the diameter and thickness of the grinding wheel 30 are detected by the inspection piece. It is simple and convenient to use and has the advantage of automatically dressing the grinding wheel on the grinding machine.

[0039] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
