Unlike the efficient air pump-driven and rationally designed dust absorption mechanism of this utility model, traditional devices often have weak suction and unreasonable pipe design, making it difficult to quickly and comprehensively collect the large amount of dust generated during the grinding process. The dust spreads rampantly inside the equipment, which not only poses a serious threat to the health of operators, but also accumulates in large quantities inside the equipment, accelerating the wear of parts, greatly shortening the service life of the equipment, and increasing maintenance costs.

This results in insufficient grinding accuracy and fails to meet the stringent requirements of high-end manufacturing for high-precision cutters. Utility Model Content

The air pump provides strong suction, and the flange pipe ensures tight connection and smooth airflow. The design of the collection box and housing facilitates centralized collection and cleaning of dust, while the connecting holes and connecting pipe ensure that dust can be smoothly transported from inside the equipment to the collection box.

[0031] Please see attached Figure 1 -Appendix Figure 6As shown, a moving mechanism 5 is provided inside the housing 1 of the equipment.

The second handle allows the operator to easily slide the storage shell out of the collection box when it is necessary to clean the dust inside the collection box and the storage shell, thereby improving the efficiency of dust cleaning and keeping the equipment clean.

[0038] Please see attached Figure 1 -Appendix Figure 6 As shown, a placement disc 6 is fixedly connected to the inner bottom of the equipment housing 1. The bottom of the equipment housing 1 is fixedly connected to a set of connecting pipes 406. The placement disc provides a stable placement platform for the diamond milling cutter, ensuring that the cutter is fixed in position during the grinding process and improving the grinding accuracy. The fixed connection between the bottom of the equipment housing and the connecting pipes allows dust to be smoothly sucked into the dust absorption mechanism from inside the equipment, effectively preventing dust from accumulating inside the equipment.

[0039] Please see attached Figure 1 -Appendix Figure 6 As shown, the two ends of the rack 509 are fixedly connected to the inside of the equipment housing 1, and the outer wall of the lead screw 503 is threadedly connected to the inside of the sliding block 511.

The threaded connection between the lead screw and the sliding block can achieve precise position adjustment. By controlling the number of rotations and direction of the lead screw, the forward and backward movement distance of the grinding mechanism can be precisely controlled, improving the grinding accuracy.

[0040] Please see attached Figure 1 -Appendix Figure 6As shown, the inner surface of the connecting frame 505 and the outer surface of the second limiting slide bar 510 are slidably connected. This sliding connection method makes the movement of the connecting frame on the second limiting slide bar smoother, and at the same time can limit the movement direction of the connecting frame, ensuring its stability and accuracy during left and right movement, thereby further improving the positioning accuracy and grinding effect of the grinding mechanism.

[0041] Working Principle: Overall Overview This device mainly consists of a dust absorption mechanism, a moving mechanism, and a grinding mechanism. Its core function is to grind diamond end mills placed on a disc. Simultaneously, the dust absorption mechanism collects the dust generated during the grinding process. The moving mechanism adjusts the position of the grinding mechanism to achieve grinding of different parts of the end mill. Working Principle of Each Part: Dust Absorption Mechanism Working Principle: Starting the Air Pump: Turning on the air pump 401, it begins to work, generating suction at its inlet end, drawing in dust. Due to the suction of the air pump 401, the dust generated during grinding passes through the connection port between the bottom of the outer casing 1 and the connecting pipe 406, and then through the connecting pipe 406, the storage shell 404, and the connecting hole 405 at the top of the collection box 403. Dust is collected and cleaned inside the collection box 403. When cleaning is needed, the storage shell 404 can be slid out of the collection box 403 by pulling the second handle 9 on the outer surface of the collection box 403, thus facilitating the cleaning of the collected dust. The moving mechanism operates in two dimensions to adjust the grinding mechanism to different positions. The screw drive enables forward and backward movement. The first motor 504 is started, and its output drives the screw 503 to rotate. The sliding block moves because the outer wall of the screw 503 and the internal thread of the sliding block 511 are connected. The rotation of the screw 503 causes the sliding block 511 to move linearly along a set of first limit rails 502. Because the bottom of the sliding block 511 is fixedly connected to the grinding mechanism 512, the grinding mechanism 512 will move in the front-back direction as the sliding block 511 moves. The gear and rack transmission realizes the left-right movement. Start the second motor: Start the second motor 507. The output end of the second motor 507 drives the gear 508 to rotate. The connecting frame moves: Since the outer wall of the gear 508 meshes with the rack 509, and the two ends of the rack 509 are fixed inside the equipment housing 1, and the inside of the connecting frame 505 is slidably connected to the outer surface of the second limiting slide bar 510, the rotation of the gear 508 will cause the connecting frame 505 to move linearly along the second limiting slide bar 510. The connecting frame 505 is connected to the mounting plate 506, the second motor 507, and other components, thereby driving the entire connecting frame to move linearly. The structure related to the receiving frame 505 moves in the left and right directions, which realizes the position adjustment of the grinding mechanism 512 in the left and right directions. During the grinding operation, the diamond milling cutter to be ground is placed on the placement disc 6 at the bottom of the equipment housing 1. The position of the grinding mechanism 512 is adjusted by the moving mechanism so that it is aligned with the part of the cutter to be ground. Then the grinding mechanism 512 is started to perform the grinding operation. During the grinding process, the dust absorption mechanism works continuously to collect the dust generated during grinding, ensuring the cleanliness of the working environment and the convenience of equipment maintenance and operation. The outer surface of the equipment housing 1 is connected to the cabinet door 7 by a hinge. When it is necessary to maintain, repair or place or take out the cutter inside the equipment, the cabinet door 7 can be opened by pulling the first handle 8 on the outer surface of the cabinet door 7 for convenient operation.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
