[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] The following gives specific embodiments.

[0026] As Figures 1-5As shown in the figure, a corner grinding device for electronic product production includes a grinding machine main body 1; a motor 11 is installed at the end of the grinding machine main body 1; the output end of the motor 11 is fixedly connected with a grinding disc 12, and the grinding disc 12 is rotatably arranged on the inner wall of the grinding machine main body 1; a semi-tooth block 13 is rotatably connected to the outer wall of the grinding machine main body 1; a belt 14 is rotatably connected to the middle of the semi-tooth block 13, and the other end of the belt 14 is rotatably connected to the middle of the semi-tooth block 13; a slide rail 15 is slidably connected to the middle of the grinding machine main body 1, and the semi-tooth block 13 and the slide rail 15 are meshed with each other; a spring rod 16 is fixedly connected to the middle of the grinding machine main body 1, and the output end of the spring rod 16 is fixedly connected to the bottom of the slide rail 15; a wire brush 17 is arranged at the end of the slide rail 15, and the wire brush 17 is in contact with the middle of the grinding disc 12; during work, the staff can install the grinding machine main body 1 in the working area, then connect the motor 11 to the power supply, and place the workpiece to be ground on the middle of the grinding machine main body 1, and cooperate with the rotating grinding disc 12 to carry out corner grinding work. By arranging a slidable slide rail 15 in the middle of the grinding machine main body 1, when the motor 11 is working, its output end can drive the semi-tooth block 13 to rotate synchronously under the action of the belt 14. After the teeth in the middle of the semi-tooth block 13 come into contact with the slide rail 15, the whole slide rail 15 is driven to move upward, and the output end of the spring rod 16 is stretched, making it have a reaction force. When the grinding disc 12 rotates, the middle of the spring rod 16 will scrape and clean the middle of the grinding disc 12 in turn, and under the action of the slide rail 15, the wire brush 17 will clean different areas of the middle of the grinding disc 12. When the teeth in the middle of the semi-tooth block 13 are disengaged from the slide rail 15, under the action of the spring rod 16, the whole slide rail 15 can be quickly pulled down and reset, and the impurities accumulated in the middle of the wire brush 17 can be cleaned by the impact vibration force. This step, combined with the arranged wire brush 17, can clean the impurities in the middle of the grinding disc 12, reducing the problem that a large amount of impurity particles accumulate on the surface of the grinding disc 12 after long-term use, which requires the staff to stop the grinding disc 12 and wipe it frequently. The arranged semi-tooth block 13, by virtue of its characteristics of contacting and disengaging in turn, enables the wire brush 17 to clean the grinding disc 12 at different heights, improving the flexibility of cleaning the grinding disc 12 and increasing the accuracy of subsequent workpiece grinding.

[0027] As Figure 4As shown in the figure, the wire brush 17 is slidably arranged in the middle of the slide rail 15; a clamping block 2 is fixedly connected to the top of the wire brush 17, and the clamping block 2 is polygonally arranged; two groups of vertical plates 21 are fixedly connected to the side wall of the slide rail 15; an elastic member 22 is fixedly connected to the inner wall of the vertical plate 21; a first sliding rod 23 is fixedly connected to the end of the elastic member 22, and the first sliding rod 23 is slidably arranged in the middle of the vertical plate 21; a pressing plate 24 matching the shape of the clamping block 2 is fixedly connected to the end of the first sliding rod 23; the other end of the elastic member 22 is fixedly connected to a push rod 25; during operation, by arranging two groups of clamping blocks 2 in the middle of the slide rail 15, when the staff needs to adjust the contact surface between the wire brush 17 and the grinding disc 12, the staff can push the middle of the push rod 25 inward, and while pushing, squeeze the middle of the elastic member 22 to deform. Subsequently, the pressing plate 24 will be disengaged from the middle of the clamping block 2. At this time, the clamping block 2 can be first pulled upward and the whole wire brush 17 can be rotated to adjust its angle. Then, the elastic force of the elastic member 22 can be used to pull and support the pressing plate 24, and the limit fixation of the clamping block 2 can be completed. This step, combined with the polygonally arranged clamping block 2, can increase the different working angles of the wire brush 17, reduce the problem that only one side of the wire brush 17 has been in frictional contact with the middle of the grinding disc 12 all the time, and make the service life of the wire brush 17 low. Under the action of the pressing plate 24, the flexibility of the clamping block 2 during operation can be improved, and the problem that the clamping block 2 shakes frequently due to large frictional resistance can be reduced.

[0028] As Figure 5 shown, a receiving groove 3 is formed in the middle of the semi-tooth block 13; two groups of shells 31 are fixedly connected to the inner wall of the receiving groove 3; a second sliding rod 32 is slidably connected to the inner wall of the shell 31; a counterweight 33 is fixedly connected to the end of the second sliding rod 32; during operation, by arranging two groups of shells 31 on the inner wall of the semi-tooth block 13, when the semi-tooth block 13 rotates and the counterweight 33 is close to the bottom, the second sliding rod 32 and the counterweight 33 can move downward under the action of gravity and hit the inner wall of the receiving groove 3, so as to clean the impurities in the inner groove of the semi-tooth block 13. After continuing to rotate the counterweight 33, the whole second sliding rod 32 can be received by the shell 31, and this process is repeated. This step, combined with the arranged counterweight 33, can reduce the problem that a large amount of caked impurities accumulate in the inner groove of the semi-tooth block 13, resulting in a large resistance when meshing with the slide rail 15 subsequently, and at the same time, it can reduce the wear when the two come into contact.

[0029] As Figure 5 shown, a rotating rod 4 is connected to the middle of the semi-tooth block 13 by a torsion spring; a baffle 41 is fixedly connected to the middle of the rotating rod 4; during operation, by arranging a rotating baffle 41 at the end of the semi-tooth block 13, the baffle 41 can block the end of the receiving groove 3. Under the action of this step and the baffle 41, the problem that a large amount of impurities directly transfer to the inner wall of the receiving groove 3 and adhere, making subsequent maintenance and cleaning troublesome, can be reduced.

[0030] like Figure 1 , 2 As shown in , 3 and 5, a connecting rod 5 is fixedly connected to the middle of the baffle 41; two groups of fan blades 51 are fixedly connected to the middle of the connecting rod 5; when working, the connecting rod 5 is provided in the middle of the baffle 41, and the connecting rod 5 can improve the fulcrum of the staff to open the baffle 41, and at the same time, the half-tooth block 13 will synchronously drive the two groups of fan blades 51 to rotate when rotating, and accelerate the air flow rate near the motor 11 when the motor 11 is working. This step can reduce the problem of slipping when the staff pulls the baffle 41 under the action of the connecting rod 5, and at the same time, the fan blades 51 can accelerate the heat dissipation speed of the motor 11 when it is working, and reduce the damage of the motor 11 after long-term use.

[0031] like Figure 3 and 5 As shown, a cleaning net 6 is provided in the middle of the fan blade 51; during operation, by providing a cleaning net 6 in the middle of the fan blade 51, when the fan blade 51 rotates, the cleaning net 6 can clean and collect the dust floating in the air. Under the action of the cleaning net 6, this step can further improve the cleanliness of the environment of the grinder body 1 when it is working, reduce the problem of multiple dust being raised, and at the same time improve the speed of subsequent maintenance by the staff.

[0032] like Figure 4 As shown, a friction pad 7 is fixedly connected to the middle of the push rod 25; when working, the friction pad 7 is arranged so that when the staff pushes or pulls the push rod 25, their hands will first come into contact with the friction pad 7. Under the action of the friction pad 7, this step can improve the stability of the contact between the push rod 25 and the hand, and reduce the accumulation of sweat on the hand, thereby reducing the phenomenon of slipping between the push rod 25 and the hand.

[0033] Working principle: The grinder body 1 is installed in the working area, and then the motor 11 is connected to the power supply, and the workpiece to be grinded is placed on the middle of the grinder body 1, and the corner grinding is performed in cooperation with the rotating grinding disc 12. A slidable slide rail 15 is provided in the middle of the grinder body 1, so that when the motor 11 is working, its output end can synchronously drive the half-tooth block 13 to rotate under the action of the belt 14, so that after the teeth in the middle of the half-tooth block 13 come into contact with the slide rail 15, the slide rail 15 is driven to move upward as a whole, and the output end of the spring rod 16 is elongated so that it has a reaction force, and when the grinding disc 12 is rotating, the middle of the spring rod 16 The middle of the grinding disc 12 will be scraped and cleaned in turn, and the wire brush 17 will clean different areas in the middle of the grinding disc 12 under the action of the slide rail 15. When the teeth in the middle of the half-tooth block 13 are separated from the slide rail 15, the slide rail 15 can be quickly pulled down and reset as a whole under the action of the spring rod 16, and the impurities accumulated in the middle of the wire brush 17 will be cleaned by the impact vibration force. By arranging two groups of blocks 2 in the middle of the slide rail 15, when the staff needs to adjust the contact surface between the wire brush 17 and the grinding disc 12, the staff can push the middle of the push rod 25 inward, and squeeze the middle of the elastic member 22 to deform while pushing, and then the pressure plate 24 will contact with the block 2 is disengaged, at this time, the block 2 can be pulled upward first, and the wire brush 17 can be rotated as a whole to adjust its angle, and the elastic force of the elastic member 22 can be used to pull and support the pressure plate 24 again, and the block 2 is limited and fixed. By arranging two groups of shells 31 on the inner wall of the half-tooth block 13, when the half-tooth block 13 is rotating and the counterweight 33 is close to the bottom, the second slide bar 32 and the counterweight 33 can move downward under the action of gravity and hit the inner wall of the storage groove 3, so as to clean the impurities in the inner groove of the half-tooth block 13, and after continuing to rotate the counterweight 33, the second slide bar 32 can be stored as a whole in cooperation with the shell 31, and this is repeated. By providing a rotating baffle 41 at the end of the half-tooth block 13, the baffle 41 can seal the end of the storage slot 3. By providing a connecting rod 5 in the middle of the baffle 41, the connecting rod 5 can lift the fulcrum of the staff to open the baffle 41. At the same time, the half-tooth block 13 will synchronously drive the two sets of fan blades 51 to rotate when it rotates, and accelerate the air flow rate near the motor 11 when the motor 11 is working. By providing a cleaning net 6 in the middle of the fan blade 51, the cleaning net 6 can clean and collect the dust floating in the air when the fan blade 51 rotates. The friction pad 7 is provided in cooperation with the provided one, so that when the staff pushes or pulls the push rod 25, his hand will first come into contact with the friction pad 7.
