DETAILED DESCRIPTION

[0030] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1The utility model provides an embodiment of a burr removal device for screw processing, comprising a fixing frame 1, the right end of the fixing frame 1 is fixedly connected to the motor 2, the left end of the motor 2 passes through the fixing frame 1, and the left end of the motor 2 is fixedly connected to the filter cartridge 3. When the motor 2 is started, it can rotate through the filter cartridge 3, thereby driving the screws placed in the filter cartridge 3 to flip and fully contact with the sand, thereby achieving grinding and deburring. The upper and lower ends of the left surface of the filter cartridge 3 are fixedly connected to the feed hopper 4. When the filter cartridge 3 rotates 180°, material can be added through the feed hopper 4 originally located below. The upper and lower ends of the filter cartridge 3 are provided with discharge ports 5, and the upper and lower ends of the filter cartridge 3 can be used for discharging material. The feed hopper 4 and the discharge port 5 are both threadedly connected with a cover plate, which can be sealed.

[0032] Reference Figure 2-Figure 3 When the filter cartridge 3 is rotated, the support unit 62 is driven by the support rod 62, and the left inner wall surface of the fixed frame 1 is provided with an annular groove 61. The left end of the support rod 62 is slidably connected to the inner surface of the annular groove 61, and the annular groove 61 can limit and support the left end of the support rod 62, so that the annular groove 61 can cooperate with the support rod 62 to support the left end of the filter cartridge 3, making the rotation of the filter cartridge 3 more stable.

[0033] A shielding unit is provided on the outside of the partition 8, and the shielding unit includes a triangular block 91, which is fixedly connected to the right inner wall surface of the filter cartridge 3, and the upper and lower ends of the left surface of the triangular block 91 are fixedly connected to a collecting hopper 92, and the surface of the collecting hopper 92 on one side away from the center of the interior of the filter cartridge 3 is fixedly connected to a connecting pipe 93. The material inside the filter cartridge 3 can completely enter the interior of the connecting pipe 93 along the inclined surface of the collecting hopper 92, and the outer wall of the collecting hopper 92 fits with the inner wall of the filter cartridge 3. The end of the connecting pipe 93 away from the collecting hopper 92 is fixedly connected to the discharge port 5. When the discharge port 5 is opened, the material can be completely discharged through the collecting hopper 92 and the connecting pipe 93, so as to avoid accumulation at the bottom end of the filter cartridge 3 and inability to discharge the material.

[0034] The left end of the triangular block 91 is provided with a receiving groove 94. When the partition 8 moves to the right, it can be inserted into the interior of the through groove 96 to fit the right surface of the filter cartridge 3. In the initial state, the right end of the partition 8 fits the left end of the through groove 96. The filter cartridge 3 is fixedly connected with a diamond rod 95. The diamond rod 95 is fixedly connected to the inside of the filter cartridge 3 in a horizontal linear array. There are multiple groups of diamond rods 95. The left end of the diamond rod 95 is provided with a through groove 96. The size of the receiving groove 94 and the through groove 96 is the same as that of the partition 8. They are adapted to each other, and the partition 8 is inserted into the inside of the through groove 96. The upper surface of the partition 8 is provided with filter holes 10, and the number of filter holes 10 is adapted to the number of the through groove 96. In the initial state, except for the filter hole 10 on the far left, the remaining filter holes 10 are all located inside the through groove 96 for blocking, and the filter hole 10 on the far left is located at the left end of the filter cartridge 3. At this time, the partition 8 will cooperate with the triangular block 91 to completely separate the upper and lower ends of the interior of the filter cartridge 3, and the right end of the partition 8 passes through the filter cartridge 3.

[0035] When multiple screws need to be deburred, the screws and abrasive can be added into the upper end of the partition 8 through the feed hopper 4 at the upper end, and then the motor 2 can be started to drive the filter cartridge 3 to rotate. During the rotation of the mixture, the abrasive will fully contact the screws to remove the burrs on the surface of the screws, and the impurities generated during the grinding process will be discharged through the filter holes of the filter cartridge 3 to achieve rapid cleaning. After the grinding is completed, the filter cartridge 3 rotates and resets. At this time, the electric push rod 7 can be started to drive the partition 8 to move to the right, so that the filter hole 10 enters the gap between the adjacent diamond rods 95, and the screws and The frosted mixture can completely reach the top of the partition 8 along the inclined surfaces of the diamond rod 95 and the triangular block 91, and the frosted sand can be discharged to the lower end of the filter cartridge 3 through the filter hole 10. Then, the electric push rod 7 is started again to drive the partition 8 to move to the left and reset, so as to completely separate the frosted sand and the screws. At this time, the motor 2 is started to drive the filter cartridge 3 to rotate 180°, and the discharge port 5 located at the bottom can be opened to discharge the screws for discharge, and the feeding can be completed at the same time by opening the discharge port 5 located above or the feed hopper 4 located above. There is no need to discharge the frosted sand and then add it into the filter cartridge 3, which can further improve the processing efficiency.

[0036] Reference Figure 2 and Figure 4The filter box 15 is then lifted up to complete the disassembly, which is convenient for the staff to carry the screws and clean the impurities.

[0037] Working principle: add the screws and abrasives into the interior of the filter cartridge 3 through the feed hopper 4 located above, and then start the motor 2 to drive the filter cartridge 3 to rotate to realize the deburring of the screws. The impurities generated during the processing will fall down through the filter cartridge 3 into the collection box 13 for collection and processing. After the processing is completed, the electric push rod 7 can be started to drive the partition 8 to move to the right, so that the abrasives pass through the filter hole 10 and enter the bottom of the filter cartridge 3, and then start the electric push rod 7 to drive the partition 8 to reset, completely separating the screws and abrasives. At this time, start the motor 2 to drive the filter cartridge 3 to rotate 180°, and open the discharge port 5 located below to completely discharge the screws, so that the screws can enter the filter box 15 for collection, and the abrasives remain in the filter cartridge 3, which is convenient for the next deburring process to be carried out quickly. There is no need to filter the mixture of screws and abrasives together before the next deburring process can be carried out, which reduces the transfer time with the abrasives and improves processing efficiency.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
