Description

Technical Field

[0001] The invention relates to the technical field of grinding machines, in particular to an environmentally friendly dust removal type grinding machine. Background Art

[0002] When using an electric grinder to grind a workpiece, the tool can be effectively and quickly ground by the rapid rotation of the grinding wheel, which effectively reduces the user's workload, and the grinding effect is significantly higher than that of manual grinding tools;

[0003] The grinding machine is not convenient for collecting the debris during the grinding process of the workpiece. The debris will splash in the opening area in front of the baffle and then fall to the ground to cause pollution. Figure 1 As shown in the figure, when grinding the end of the circular workpiece c by a grinding machine, the worker needs to hold the top of the workpiece and then stand on one side of the base to make the end of the workpiece contact with the grinding wheel and then continuously rotate the workpiece to complete the grinding. The grinding machine is provided with a support plate, and the support plate is fixedly connected to the base. The support plate supports the workpiece during grinding. However, during actual grinding, the debris generated when the grinding wheel contacts the workpiece will splash upward at an inclined angle from below, such as Figure 1 The area between the two dotted lines a and b in Figure A is the area where debris splashes. At this time, most of the splashing debris will be blocked by the support plate, and only a small amount of debris will splash above or below the support plate;

[0004] However, after a long period of grinding, the radius of the grinding wheel will gradually shrink. When the grinding wheel is only one-third of the initial diameter, the grinding wheel needs to be replaced. During the gradual shrinkage of the grinding wheel diameter, the position of the support plate on the base does not change accordingly, which will cause the distance between the grinding wheel and the support plate to gradually increase. Therefore, when grinding, the workpiece needs to be gradually brought closer to the grinding wheel for grinding. As the workpiece approaches the grinding wheel and the distance between the support plate and the grinding wheel increases, Figure 1 As shown in Figure B, the area of ​​flying debris, that is, the area between dotted lines a and b, will gradually tilt upward, so it will directly splash onto the face of the worker holding the workpiece, posing a safety hazard, and the area will gradually tilt upward as the diameter of the grinding wheel decreases.

[0035] See also Figure 1-Figure 11 The present invention provides a technical solution: an environmentally friendly dust removal grinding machine, comprising a base 1, a driving mechanism 2 is arranged on the base 1, baffles 3 are fixedly connected to the left and right side walls of the driving mechanism 2, grinding wheels 4 are arranged inside the baffles 3, the driving mechanism 2 is used to drive the two grinding wheels 4 to rotate, a support block 5 is arranged on the top of the base 1, and an adjustment group is arranged on the support block 5;

[0036] The adjustment group includes a support plate 6 and a through hole 9. The support plate 6 is slidably connected to the support block 5. The top of the support plate 6 is U-shaped. The inner wall of the support plate 6 is rotatably connected to a first guide plate 7. The first guide plate 7 is slidably connected to a second guide plate 8. The second guide plate 8 is rotatably connected to the baffle 3. Both the first guide plate 7 and the second guide plate 8 are U-shaped. The through hole 9 is opened on the baffle 3, and a collection box 10 is arranged directly below the through hole 9.

[0037] like Figure 2-Figure 4 and Figure 6 As shown:

[0038] Before grinding the workpiece, first drive the two support plates 6 to move along the support block 5 toward the grinding wheel 4;

[0039] Moving work of support plate 6:

[0040] Manually push the two support plates 6 along the support block 5 to move to a suitable distance from the grinding wheel 4 and then stop pushing the support plates 6. At this time, the support plates 6 will stay at this position. When pushing the support plates 6, the moving distance of the support plates 6 on the support block 5 needs to be changed according to the diameter of the grinding wheel 4.

[0041] During the movement of the support plate 6, the first guide plate 7 will rotate around the rotation axis and drive the second guide plate 8 to rotate around the rotation axis, and the first guide plate 7 and the second guide plate 8 will expand and contract accordingly, so that the horizontal distance of the support plate 6 during the movement will not change (the setting height of the support plate 6 should be slightly lower than the center height of the grinding wheel 4), that is, the longer the distance the support plate 6 moves backward, the smaller the diameter of the grinding wheel 4, then the change in the rotation angle of the first guide plate 7 and the second guide plate 8 will adapt to the support plate 6, so that the support plate 6 and the first guide plate 7 and the second guide plate 8 can automatically block the area where the debris splashes, thereby preventing the debris from splashing onto the face of the staff when the diameter of the grinding wheel 4 becomes smaller, and also preventing the debris from splashing and polluting the working space;

[0042] Grinding work of the grinding wheel 4 on the workpiece:

[0043] The base 1 is supported, and the driving mechanism 2 drives the grinding wheel 4 to rotate. The driving mechanism 2 can be understood as a mechanism with a motor fixed inside the shell. It is common knowledge in the prior art that during this process, the flying debris will fall through the obstruction of the support plate 6, and will move along the first guide plate 7 and the second guide plate 8 to the through hole 9 inside the baffle 3, and then fall through the through hole 9 to the collection box 10 for collection, thereby avoiding large-scale pollution caused by the splashing of debris and facilitating collection.

[0044] The baffles 3 are composed of a fixed plate 11 and a movable plate 12. The fixed plate 11 is fixedly connected to the side wall of the driving mechanism 2. The through hole 9 is opened on the fixed plate 11. The second guide plate 8 is also rotatably connected to the fixed plate 11. The movable plate 12 is slidably connected to the fixed plate 11. A scraper 13 is fixedly connected to the inner wall of the fixed plate 11. When the movable plate 12 rotates, the scraper 13 can scrape off the debris remaining on the movable plate 12.

[0045] like Figure 2-Figure 5 As shown:

[0046] Before the grinding wheel 4 stops working, the movable plate 12 is in a forward rotating state, and at this time, the opening area between the fixed plate 11 and the movable plate 12 can be shielded in a large range (the maximum extent is that the front end of the movable plate 12 is at the same height as the central axis of the grinding wheel 4, and it can be shielded at this time), so that foreign debris or tools will not easily enter between the grinding wheel 4 and the baffle 3. Before the grinding wheel 4 works, the movable plate 12 is first rotated backward, so that the working area of ​​the grinding wheel 4 (that is, the opening area between the movable plate 12 and the fixed plate 11 when it rotates backward) is opened;

[0047] Then the support plate 6 can be moved and the grinding wheel 4 can be used to grind the workpiece.

[0048] When the grinding wheel 4 finishes grinding the workpiece, the movable plate 12 is rotated forward to cover the working area of ​​the grinding wheel 4 together with the fixed plate 11. In addition, during the rotation of the movable plate 12, the fixed plate 11 and the scraper 13 are stationary, which enables the scraper 13 to guide the first guide plate 7 and the second guide plate 8 to the movable plate 12 and the through hole 9, and scrape the debris that has not completely fallen into the collection box 10 into the collection box 10 for easy collection.

[0049] A driving group is provided on the base 1, the driving group includes two monitoring groups and a locking group, and the driving group is used to drive the two support plates 6 to move;

[0050] The driving group includes a rotating ring 14 and two first springs 31, the two first springs 31 are respectively fixedly connected between the two support plates 6 and the inner wall of the support block 5, the rotating ring 14 is fixedly connected between the two movable plates 12, the two side walls of the rotating ring 14 are fixedly connected with gear rings 15, the lower part of the gear rings 15 are meshed with first gears 16, the first gears 16 are rotatably connected to the base 1, the lower part of the first gears 16 are meshed with first rack rods 17, the two first rack rods 17 are fixed together on the side wall of the support block 5, and the support block 5 is slidably connected to the base 1;

[0051] The two monitoring groups are used to stop the movement after the two support plates 6 and the two grinding wheels 4 have a fixed distance, and then lock the two support plates 6 and the rotating ring 14 through the locking group.

[0052] The locking group includes an insertion rod 18 and a slot 19. The slot 19 is opened on the swivel 14. The insertion rod 18 is located directly below the slot 19 and is slidably connected to the base 1. A second spring 32 is fixedly connected between the insertion rod 18 and the base 1. Top plates 20 are provided on the left and right side walls of the insertion rod 18. The two top plates 20 can rise and fall with the insertion rod 18. Second rack rods 22 are slidably connected to the two top plates 20. The two second rack rods 22 are respectively slidably connected to the left and right side walls of the support block 5. Second gears 23 are provided directly above the two second rack rods 22. The second gear 23 does not mesh with the second rack rod 22. The two second gears 23 are respectively provided at the bottom of the two support plates 6.

[0053] The two second gears 23 are rotatably connected to the two support plates 6 , respectively. A third rack rod 24 is meshed above the two second gears 23 , and the two third rack rods 24 are fixedly connected to the support block 5 .

[0054] The monitoring group includes a transverse plate 25 and a detection plate 28. The detection plate 28 is slidably connected to the support plate 6. A fifth spring 30 is fixedly connected between the detection plate 28 and the support plate 6. The front end of the detection plate 28 is L-shaped. The transverse plate 25 is fixedly connected to the side wall of the insertion rod 18. The transverse plate 25 is slidably connected to the top plate 20. A third spring 26 is sleeved between the transverse plate 25 and the top plate 20. A support rod 27 is slidably connected to the side wall of the transverse plate 25. A fourth spring 29 is fixedly connected between the support rod 27 and the transverse plate 25. The support rod 27 is located in front of the detection plate 28. An inclined transition surface is provided at the front end of the detection plate 28.

[0055] As shown in Figure 7- Fig.11 As shown:

[0056] When the grinding wheel 4 is not working, the movable plate 12 blocks the upper part of the grinding wheel 4, but the slot 19 does not overlap with the insertion rod 18. Instead, the slot 19 is located to follow the rotation of the rotating ring 14 to the upper part, and the side wall of the rotating ring 14 presses down the insertion rod 18, that is, the second spring 32 is in a compressed state at this time;

[0057] When the grinding wheel 4 is about to work, the rotating ring 14 and the gear ring 15 are rotated backwards first, at which time the gear ring 15 will mesh with the first gear 16 and drive the first rack rod 17 and the support block 5 to move backwards through the first gear 16, thereby enabling the two support plates 6 to move backwards together. At this time, the first spring 31 will not be stretched, and with the movement of the support block 5 and the support plate 6, the top plate 20 will gradually slide into the inside of the second rack rod 22, and the support rod 27 will also move with it under the elastic reset action of the fourth spring 29. After the insertion rod 18 coincides with the slot 19, it will be inserted into the slot 19 under the action of the second spring 32 to fix the rotating ring 14 and the movable plate 12;

[0058] Because the rotation angle of the swivel 14 is fixed, that is, the distance that the support block 5 slides backward is also fixed, and the detection plate 28 will first contact the grinding wheel 4 before the support block 5 moves to the limit distance, but the detection plate 28 will not slide directly backward along the support plate 6 under the obstruction of the rear support rod 27, and the rear end of the detection plate 28 protrudes backward relative to the support plate 6, that is, at this time, the support plate 6 is at a certain distance from the grinding wheel 4 (under normal conditions, the minimum distance between the support plate 6 and the grinding wheel 4 can be 1-3 mm, and can also be set according to needs). After the detection plate 28 contacts the grinding wheel 4, the support plate 6 slides forward along the support block 5 and stretches the first spring 31, and then as the support block 5 continues to move, the support plate 6 will stay at this position due to the contact between the detection plate 28 and the grinding wheel 4, and will slide forward relative to the support block 5. At this time, the first spring 31 is stretched, and the second gear 23 will rotate along the movement of the third rack rod 24;

[0059] After the insertion rod 18 is inserted into the slot 19, the second spring 32 is elastically relaxed, and the insertion rod 18 drives the top plate 20 and the cross plate 25 to rise. During the rising process of the top plate 20, the second rack rod 22 is driven to slide along the support block 5 to a position where the second gear 23 is released, and the second gear 23 is locked through the meshing of the two, thereby locking the support plate 6 to prevent the support plate 6 from moving due to small friction during the grinding work;

[0060] When the second rack rod 22 contacts the second gear 23, the insertion rod 18 is not completely inserted into the slot 19. At this time, the cross bar 25 will gradually compress the third spring 26 as the insertion rod 18 continues to rise, and then the cross bar 25 drives the support rod 27 to rise to a position completely separated from the detection plate 28. At this time, the support rod 27 will rise above the detection plate 28, and then the elastic reset action of the fifth spring 30 will make the detection plate 28 enter the inside of the support plate 6. At this time, the support plate 6 will have a certain distance from the grinding wheel 4 without contacting;

[0061] When the grinding work is completed, the plunger 18 is manually pressed down to drive the cross plate 25 to descend, and the cross plate 25 will first drive the support rod 27 to descend, and the support rod 27 will push the detection plate 28 to re-enter the support plate 6 through the inclined surface at the end of the detection plate 28, and then the cross plate 25 will also drive the second rack rod 22 to descend to the initial position, and after the plunger 18 is disengaged from the slot 19, the swivel 14 can be directly reversed to drive the support block 5 to slide forward and reset;

[0062] In this way, when the support plate 6 is moved, the two detection plates 28 can enable the two support plates 6 to reserve the same distance at the same time according to the different diameters of the two grinding wheels 4, thereby avoiding contact between the grinding wheels 4 and the support plates 6 and meeting the spacing requirements between the support plates 6 and the grinding wheels 4.

[0063] The rear end of the detection plate 28 is embedded with a ball.

[0064] The ball bearings can reduce the friction between the detection plate 28 and the grinding wheel 4, thereby preventing the grinding wheel 4 from shaking and causing irregular wear when the two are in contact. The ball bearings can be any one of those in the prior art, so no detailed description is required.

[0065] The collecting box 10 is slidably connected to the base 1 .

[0067] The arrangement of the sliding connection facilitates the disassembly of the collecting box 10 .
