Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a water-spraying dust removal chuck. Background Technology

[0002] In the field of machining, especially in dry or semi-dry machining scenarios such as turning, grinding, and cutting, the chuck, as the core component for holding the workpiece, often generates a large amount of metal dust or debris due to the intense friction between the cutting tool and the workpiece during operation. This dust not only pollutes the working environment and endangers the respiratory health of operators, but also accelerates the wear of precision components such as machine tool guideways and bearings, and may even pose a risk of dust explosion.

[0003] Currently, air jet cleaning is widely used in the industry, but air jet dust collectors suffer from rigid airflow rebound problems, especially with sticky dust (such as metal and oil mixtures) where the removal rate is less than 40%, and the cost of compressed air consumption is high. These problems have become urgent issues for researchers in this field to address. Therefore, it is essential to design a water jet dust collector that is both practical and highly efficient in cleaning. Summary of the Invention

A connecting plate 403 is fixed in the middle of the cover plate 402. The left side of the connecting plate 403 is in rolling connection with the rotating shaft 5. A fixed shaft 405 is bolted to the right side of the connecting plate 403. A sleeve 406 is connected to the intermediate shaft body bearing of the fixed shaft 405. A guide sleeve 407 is connected to the right end shaft body bearing of the fixed shaft 405. A support block 404 is fixed on the side of the protective cover 4 away from the bearing seat 3. A drive gear 201 is rolled on the right side of the support block 404. The drive gear 201 meshes with the driven gear 401. The drive gear 201 is keyed to the second motor 2. A lifting ring 301 is fixed on the top of the bearing housing 3 to facilitate the transport of the entire device. A control panel 302 is fixed on the front side of the bearing housing 3. The first motor 111 and the three-way valve 109 are electrically connected to the control panel 302. The vision sensor 1041 is signal connected to the first motor 111. The vision sensor 1041 is used to send control signals to the first motor 111 to achieve drive. The guide sleeve 407 has a water inlet 13 at the right end. The fixed shaft 405, rotating shaft one 5, rotating shaft two 6 and rotating shaft three 801 all have a through circular hole 501 in the middle. The through holes 501 in the fixed shaft 405, rotating shaft one 5, rotating shaft two 6 and rotating shaft three 801 form a water channel, which allows water to be transported from the rear to the front chuck body 101.

[0019] Working principle: Water is introduced at inlet 13, and transported through the fixed shaft 405, rotating shaft one 5, rotating shaft two 6, and the internal through-hole 501 of rotating shaft three 801 to the interior of cross 9. Cross 9 has an internal passage 902 that transports the water to the bottom inlet of three-way valve 109. When water needs to be sprayed onto the side of the parts, the control panel 302 controls the valve of the electric three-way valve 109, causing water to flow out from the outlet 903 in the middle of cross 9 and opening the channel connecting the water pipe 108. Water enters the side nozzle 104 through the pipe 108 and is sprayed out. When the vision sensor 1041 detects dust particles on the surface of the part, it sends an electrical signal to the first motor 111, driving the first motor 111 to operate, thereby driving the connecting rod 110 to rotate, and further driving the side nozzle 104 to rotate toward the central axis of the rotating shaft 801. This causes the first motor 111 to rotate clockwise and counterclockwise alternately, so that the nozzle can continuously move closer to and away from the rotating shaft 801, thus expanding the spray range.

[0020] When water needs to be sprayed on the end face of the part, the control panel 302 is used to control the valve of the electric three-way valve 109, so that the water flows to the end face nozzle 105. A pad 901 is set on the cross 9 to keep a certain distance between the part and the end face nozzle 105, so that the cleaning will not be incomplete due to the distance being too close. If necessary, the angle of the end face nozzle 105 can be manually adjusted according to the size of the part. At the same time, the end face nozzle 105, the side nozzle 104 and the water outlet 903 can spray water simultaneously. The water outlet 903 is always open, which can cool the processed parts and improve the dust removal effect. By controlling the opening and closing of the valve, the water flow rate into the end face nozzle 105 and the side nozzle 104 can be adjusted to better meet the needs of different parts.
