Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] A grinding device for processing crane parts, as Figure 1 and Figure 2 shown, includes a grinding table 1, a mounting frame 2, and two side plates 3 provided at the top end of the grinding table 1. The vertical mounting frame 2 is located between the two side plates 3 above the grinding table 1. A pushing mechanism for driving the mounting frame 2 to move back and forth, left and right is provided on the two side plates 3. A power member for driving the mounting frame 2 to move vertically is provided on the pushing mechanism. A rectangular protective frame 4 is slidably connected to the mounting frame 2 through a sliding member, and the bottom end of the mounting frame 2 is located inside the protective frame 4. A grinding motor 5 is provided at the bottom end of the mounting frame 2, and a grinding disc 6 located inside the protective frame 4 is provided at one end of the rotating shaft of the grinding motor 5.

[0023] As Figure 1 and Figure 2, during use, place the part on the grinding table 1 such that the part is directly below the protective frame 4. Then, drive the mounting frame 2 to move vertically downward by the power component. At this time, the protective frame 4 moves downward following the mounting frame 2. When the bottom end of the protective frame 4 abuts against the top end of the grinding table 1, the part is located within the protective frame 4. Then, the power component continues to drive the mounting frame 2 to move vertically downward and turn on the grinding motor 5. At this time, the protective frame 4 will stop moving, and the mounting frame 2 that continues to move downward will gradually enter the protective frame 4 through the sliding component. The rotating shaft of the grinding motor 5 drives the grinding disc 6 to rotate until the grinding disc 6 contacts the upper surface of the part. At this time, the part can be ground by the grinding disc 6. During grinding, the protective frame 4 blocks the splashing waste chips, improving the safety of use;

[0024] During the grinding process, drive the mounting frame 2 to move back and forth, left and right by the pushing mechanism. At this time, the grinding range of the upper surface of the part can be improved. When the pushing mechanism drives the mounting frame 2 to move back and forth, left and right, the protective frame 4 will not move back and forth, left and right following the mounting frame 2 through the sliding component, which is simple and convenient to use.

[0025] Such as Figure 1 , the pushing mechanism includes sliding grooves 7 horizontally arranged on the mutually close sides of the two side plates 3, and sliding plates 8 are horizontally slidably connected in both of the two sliding grooves 7. The two sliding plates 8 are connected by a suspension plate 9. The suspension plate 9 is horizontally arranged, and a sleeve 10 is horizontally slidably connected on the suspension plate 9. An extension plate 12 is provided at the top end of the outer wall of the sleeve 10. Two opposite baffles 13 are provided at the top end of the suspension plate 9, and a first lead screw 14 is rotatably connected between the two baffles 13. One end of the first lead screw 14 passes through the extension plate 12 and is threadedly connected to the extension plate 12. A first motor 15 for driving the first lead screw 14 to rotate is provided on one of the baffles 13. A second lead screw 16 is rotatably connected between the opposite two side walls of one of the sliding grooves 7, and one end of the second lead screw 16 passes through the sliding plate 8 and is threadedly connected to the sliding plate 8. A second motor 17 for driving the second lead screw 16 to rotate is provided on the side plate 3;

[0026] The power component includes a first electric cylinder 18 vertically arranged at the bottom end of the sleeve 10, and the piston rod of the first electric cylinder 18 is fixedly connected to the top end of the mounting frame 2.

[0027] Such as Figure 1 , when it is necessary to drive the mounting frame 2 to move back and forth, left and right, turn on the first motor 15. The rotating shaft of the first motor 15 drives the first lead screw 14 to rotate. At this time, since one end of the first lead screw 14 passes through the extension plate 12 and is threadedly connected to the extension plate 12, when the first lead screw 14 rotates, it can push the extension plate 12 to drive the sleeve 10 to move horizontally along the length direction of the suspension plate 9 on the suspension plate 9. At this time, the sleeve 10 will drive the mounting frame 2 to move left and right through the first electric cylinder 18;

[0028] By turning on the second motor 17, the rotating shaft of the second motor 17 drives the second lead screw 16 to rotate. At this time, since one end of the second lead screw 16 passes through the sliding plate 8 and is threadedly connected to the sliding plate 8, when the second lead screw 16 rotates, it can push the sliding plate 8 to drive the hanging plate 9 to move back and forth between the two side plates 3. At this time, the sleeve 10, the first electric cylinder 18, and the mounting frame 2 will move back and forth following the hanging plate 9;

[0029] When it is necessary to push the mounting frame 2 to move vertically, just turn on the first electric cylinder 18. At this time, the piston rod of the first electric cylinder 18 will push the mounting frame 2 to move vertically, which is simple and convenient to use.

[0030] Such as Figure 1 and Figure 2 , the sliding member includes a vertical plate 19, a first sliding column 20, and a second sliding column 21. The first sliding column 20 is horizontally slidably connected between the opposite sides of the protective frame 4 along the length direction of the protective frame 4. The second sliding column 21 is horizontally slidably connected between the opposite sides of the protective frame 4 along the width direction of the protective frame 4. The first sliding column 20 and the second sliding column 21 are vertically offset. The vertical plate 19 is vertically located on one side of the mounting frame 2, and two opposite sliding grooves 22 are vertically provided on the side of the vertical plate 19 close to the mounting frame 2. Two sliding plates 23 are vertically slidably connected in the two sliding grooves 22. One side of the two sliding plates 23 facing away from the bottom of the sliding groove 22 is fixedly connected to the mounting frame 2. Two communication grooves 24 are formed on the vertical plate 19, and one end of the first sliding column 20 and the second sliding column 21 respectively horizontally pass through the two communication grooves 24. At this time, one end of the second sliding column 21 passes through the mounting frame 2. A bottom plate 25 located inside the mounting frame 2 is provided on the side of the vertical plate 19 close to the mounting frame 2, and a compression spring 26 is provided between the bottom plate 25 and the top end inside the mounting frame 2. Two opposite limiting columns 27 are vertically provided at the top end of the grinding table 1. Two opposite inserting cylinders 28 are provided on the outer wall of the protective frame 4. The top ends of the two limiting columns 27 respectively pass through the two inserting cylinders 28.

[0031] Such as Figure 1 and Figure 2 , the top end of the sliding plate 23 contacts the top wall of the top end of the sliding groove 22. At this time, it is the initial position of the sliding plate 23. When the mounting frame 2 moves downward, the vertical plate 19, the first sliding column 20, the second sliding column 21, the bottom plate 25, the compression spring 26, and the protective frame 4 will all move downward following the mounting frame 2. When the bottom end of the protective frame 4 contacts the top end of the grinding table 1 and the mounting frame 2 continues to move downward, since the bottom end of the protective frame 4 contacts the top end of the grinding table 1, the protective frame 4 will stop moving downward. Then the mounting frame 2 continues to move downward. At this time, the mounting frame 2 will drive the sliding plate 23 to move downward in the sliding groove 22. At this time, the compression spring 26 will be compressed, so that the bottom end of the protective frame 4 is tightly pressed against the top end of the grinding table 1 until the grinding disc 6 contacts the parts inside the protective frame 4, and the parts can be ground;

[0032] Then, when the installation frame 2 moves forward, backward, left and right, because the top end of the limit column 27 passes through the insert tube 28, and the first slide column 20 slides horizontally along the length direction of the protection frame 4 and is connected between the opposite sides of the protection frame 4, and the second slide column 21 slides horizontally along the width direction of the protection frame 4 and is connected between the opposite sides of the protection frame 4, when the installation frame 2 moves forward, backward, left and right, through the cooperation of the first slide column 20 and the second slide column 21 and the two connecting grooves 24 on the vertical plate 19 and the two limit columns 27 and the two insert tubes 28, the protection frame 4 can be prevented from moving forward, backward, left and right with the installation frame 2, which is simple and convenient to use.

[0033] like Figure 2 The protective frame 4 is provided with a clamping mechanism for clamping parts. The purpose of this setting is that when the bottom end of the protective frame 4 collides with the top end of the grinding table 1, the parts in the protective frame 4 are clamped by the clamping mechanism on the protective frame 4. At this time, the displacement of the parts when the grinding disc 6 is grinding the parts can be reduced, and it is simple and convenient to use.

[0034] like Figure 2 and Figure 3 and Figure 4 The clamping mechanism includes two clamping plates 29 horizontally slidably connected between opposite sides of the protective frame 4 along the length direction of the protective frame 4, and a pad 30 is provided on one side of the top of the two clamping plates 29, and a support plate 31 is horizontally provided on the top of the two pads 30, and the two support plates 31 are staggered up and down, and the two support plates 31 are provided with a first rack 32 on the side close to each other, and a rotating groove 33 is opened on the inner wall of the protective frame 4 close to the two support plates 31, and a rotating shaft 34 is rotatably connected in the rotating groove 33, and the rotating shaft 34 is coaxial with the rotating shaft 34. A first gear 35 is provided in the protective frame 4, and the first gear 35 is located between the two support plates 31 and meshed with the two first racks 32. A second gear 36 is coaxially provided on the rotating shaft 34 and located outside the protective frame 4. A movable plate 37 is horizontally slidably connected to one end of the outer wall of the protective frame 4 close to the second gear 36, and a second rack 38 meshing with the second gear 36 is provided on the movable plate 37 along the length direction of the movable plate 37. A second electric cylinder 39 for pushing the movable plate 37 to move horizontally is provided on the protective frame 4.

[0035] like Figure 2 and Figure 3 and Figure 4, after the bottom end of the protection frame 4 abuts against the top end of the grinding table 1, the two clamping plates 29 will be located on the opposite sides of the part respectively. At this time, the second electric cylinder 39 is opened, and the piston rod of the second electric cylinder 39 pushes the moving plate 37 to move horizontally. At this time, the second gear 36 can be driven to rotate through the second rack 38 on the moving plate 37. At this time, the second gear 36 will drive the first gear 35 to rotate through the rotating shaft 34. At this time, the first gear 35 will drive the two support plates 31 to approach each other respectively through the two first racks 32 engaged with it. At this time, the two support plates 31 will drive the two clamping plates 29 to approach each other respectively through the cushion plates 30 until the two clamping plates 29 are both in contact with the part. At this time, the clamping of the part can be completed. At this time, the displacement of the part during the grinding of the part by the grinding disc 6 can be reduced, and it is simple and convenient to use.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model also intends to include these modifications and variations.
