DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-7 , the present invention provides a technical solution:

[0029] A grinding degree adjustment mechanism, comprising

[0030] A vertical bracket 1 is vertically arranged on a base 2. A through slot 3 is provided in the vertical bracket 1 along the height direction. A first screw rod 4 is movably arranged in the through slot 3. The first screw rod 4 extends to one end of the top of the vertical bracket 1 and is transmission-connected to a first motor 5. A first slider 6 is movably arranged in the through slot 3. The first slider 6 is transmission-connected to the first screw rod 4. The first slider 6 is fixedly connected to a grinding motor 7 through a connecting block. A grinding head 8 is arranged on the main shaft of the grinding motor 7, and the grinding head 8 can be replaced. By arranging the first screw rod 4, the first motor 5 and the first slider 6, under the action of the first motor 5, the first screw rod 4 is driven to rotate, and the first slider 6 is linked to move up and down along the through slot 3, and finally the grinding head 8 is linked to move up and down, so as to realize the grinding of the lower workpiece;

[0031] The driving plate 9 is arranged on the back of the vertical bracket 1 and is fixedly connected to the first sliding block 6. The driving plate 9 is provided with a first guide rod 10 in the vertical direction. The first guide rod 10 is movably sleeved with a sliding sleeve 11. The sliding sleeve 11 is rotatably connected to the adjusting wheel 12 through a rotating shaft. By arranging the first guide rod 10 and the sliding sleeve 11, the adjusting wheel 12 can remain stable during the process of moving up and down along the driving plate 9 to avoid left and right shaking, which affects the grinding accuracy; a driving chain 13 is arranged around the adjusting wheel 12. In the technical solution of this embodiment, the adjusting wheel 12 and the driving chain 13 are a sprocket and chain structure. One end of the driving chain 13 is fixedly connected to the driving plate 9, and this end is a fixed end and cannot move. The other end is connected to the first adjusting rod 14, which moves up and down synchronously with the first adjusting rod 14. A rotating handle is arranged at the end of the first adjusting rod 14. The first adjusting rod 14 is threadedly connected to a connecting block 15 on the driving plate 9. 4 is fixedly provided with a driving sleeve 16, a connecting sleeve 17 is movably sleeved on the driving sleeve 16, the connecting sleeve 17 is connected to a pointer 18, a dial 19 corresponding to the pointer 18 is provided on the connecting block 15, and a first sensor 20 is provided on the adjusting wheel 12; after leveling and setting the tool, by turning the rotating handle, the first adjusting rod 14 is linked to rotate, and under the action of the thread, the first adjusting rod 14 moves upward, and the pointer 18 and the dial 19 can accurately record the distance the first adjusting rod 14 moves upward, so that the value of each grinding can be clearly known. Since the first adjusting rod 14 is connected to the driving chain 13, the first adjusting rod 14 is linked to the connecting end of the driving chain 13 to move upward synchronously during the upward movement. Since the driving chain 13 is arranged around the adjusting wheel 12 to form a pulley line group structure, the upward movement distance of the adjusting wheel 12 is only half of the movement distance of the first adjusting rod 14, thereby finally improving its grinding accuracy;

[0032] The fixing plate 21 is fixedly arranged on the back of the vertical bracket 1 and corresponds to the driving plate 9. A group of second guide rods 22 are symmetrically arranged at both ends of the fixing plate 21. A second sensor 23 corresponding to the first sensor 20 is sleeved on the second guide rod 22. The first sensor 20 and the second sensor 23 are electrically connected to the first motor 5, so that when the first sensor 20 and the second sensor 23 are in contact, the first motor 5 is controlled to stop running. The fixing plate 21 is transmission-connected to the second adjusting rod 24, and the upper end of the second adjusting rod 24 is movably connected to the second sensor 23. Before grinding, leveling and tool setting are required: driven manually The grinding head 8 moves downward and contacts the surface of the workpiece to be ground (the grinding head 8 does not rotate at this time), and then the second adjusting rod 24 is rotated to drive the second sensor 23 to move upward until it contacts the first sensor 20. At this time, the first adjusting rod 14 is adjusted upward, and the first sensor 20 at the bottom is linked to move upward half the distance, and the distance moved by the first sensor 20 is the actual value of each grinding; during the grinding process, when each grinding depth is reached, the first sensor 20 will contact the second sensor 23, and then control the first motor 5 to stop rotating, so that the grinding head 8 does not move downward;

[0033] A second screw rod 25 is rotatably disposed on the base 2, a second motor 26 for driving the second screw rod 25 to rotate is disposed at the end thereof, a second slider 27 is movably disposed on the base 2, the second slider 27 is transmission-connected to the second screw rod 25, and under the driving action of the second motor 26, the second slider 27 is driven to move laterally along the base 2, so that the workpiece can continuously pass through the grinding head 8, thereby realizing upward grinding in the lateral direction;

[0034] A driving box 29 is movably arranged on the second slider 27, a third screw rod is arranged on the second slider 27, a third motor 28 is arranged on the second slider 27, the third motor 28 is transmission-connected to the driving box 29, and the third motor 28 can drive the upper workpiece to move along the longitudinal direction, so as to grind the workpiece in the longitudinal direction, and finally make the surface of the workpiece to be ground contact with the upper grinding head 8 to achieve grinding; and

[0035] The fixed table 30 is fixedly arranged on the upper part of the drive box 29. The workpiece to be ground is fixed on the fixed table 30. There are multiple groups of clamping blocks 31 for clamping the workpiece in a circular array around the fixed table 30. In the technical solution of this embodiment, there are four groups of clamping blocks 31. The clamping blocks 31 are fixedly connected to the upper end of the connecting block 2 32 passing through the fixed table 30. The lower end of the connecting block 2 32 is threadedly connected to the driving screw 33. The driving screw 33 extends to one end of the driving box 29. The first driving wheel 34 is meshed with the second driving wheel 35 arranged at the upper end of the rotating shaft 36. The lower end of the rotating shaft 36 is provided with a third driving wheel. The third driving wheel 37 is meshed with the fourth driving wheel 38 arranged on the driving rod 39. The other end of the driving rod 39 is provided with a rotating hand wheel 40. When the workpiece needs to be clamped, the workpiece is first placed on the fixed table 30 (the surface to be ground faces upward), and then the rotating hand wheel 40 is rotated to link the fourth driving wheel 38 to rotate. Under the action of the third driving wheel 37, the rotating shaft 36, the second driving wheel 35 and the first driving wheel 34, the driving screw 33 is linked to rotate. Since the connecting block 2 32 is threadedly connected with the driving screw 33, the connecting blocks 2 32 and the clamping blocks 31 around are finally driven to synchronously approach the center of the circle to achieve clamping of the workpiece.

[0036] The present application also provides a grinding device, comprising the above-mentioned grinding degree adjustment mechanism.
