[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. For this fastener grinding and processing equipment, the three-jaw chuck provided on the fixed processing base cooperates with the grinding head on the advancing processing base for fastener grinding and processing. A sound insulation cover is installed to isolate and protect the grinding operation space. The grinding is safe and low-noise.

The grinding can reduce temperature, prevent dust, be environmentally friendly and energy-saving. The equipment runs stably. The three-jaw chucks provided on the opposite sides of the fixed processing base cooperate with the worm gear, worm and rotating motor.

[0033] The usage method of this embodiment is as follows: According to the model size of the fasteners produced in batches, the first sound insulation cover 5 on the advancing processing seat 3 is moved and adjusted through the adjusting mechanism 4, so that the first sound insulation cover 5 can be closed with the second sound insulation cover 51 during the grinding process. That is, the first motor 44 drives the first threaded rod 42 in the limiting groove 41 to rotate, and the threaded seat 43 on the first threaded rod 42 moves in the limiting groove 41, driving the first sound insulation cover 5 to move and adjust on the advancing processing seat 3. Tighten the locking bolt 46 on the advancing processing seat 3, and the locking bolt 46 locks the locking disc 45 between the first motor 44 and the first threaded rod 42 to prevent the adjusted first sound insulation cover 5 from moving during the grinding process. The second motor 72 on the support 71 drives the second threaded rod 73 to rotate, and the advancing processing seat 3 reciprocates and advances on the top of the processing machine base 1 through the threaded sleeve 7. The limiting block 74 at the bottom of the advancing processing seat 3 slides in the limiting chute 75 on the top of the processing machine base 1. During the process of the advancing processing seat 3 moving on the processing machine base 1, the first sound insulation cover 5 moves on the processing machine base 1 along with the advancing processing seat 3, and the limiting sliders at the lower ends of the opposite sides of the first sound insulation cover 5 are limited and guided to slide on the sliding rod 19 in the limiting groove 18. During grinding, first, the fasteners are loaded and clamped on the fixed processing seat 2 on the side away from the advancing processing seat 3 through the three-jaw chuck 21, and the fasteners are fixed on the fixed processing seat 2. The rotating motor 25 drives the worm 24 to rotate, and the rotation of the worm 24 drives the meshing worm wheel 23 to rotate. The rotation of the worm wheel 23 drives the fixed processing seat 2 to rotate on the processing machine base 1 through the rotating shaft 22, and the second sound insulation cover 51 rotates synchronously with the fixed processing seat 2 to rotate the three-jaw chuck 21 carrying the fasteners to correspond to the advancing processing seat 3. Then, the advancing mechanism pushes the advancing processing seat 3 to move towards the fixed processing seat 2, and the grinding head 63 approaches the fasteners. The sound insulation board 53 on the second sound insulation cover 51 is inserted into the sound insulation groove 52 on the first sound insulation cover 5, and the sound insulation board 53 and the sound insulation groove 52 form a sound insulation closure. When the sound insulation board 53 is inserted into the sound insulation groove 52, the sensor 521 senses that the sound insulation cover is closed, and the solenoid valve 83 is opened. The servo motor drives the grinding seat 6 to rotate on the advancing processing seat 3, and drives the grinding head 63 to rotate on the fasteners through the fixed disc 61 and the connecting shaft 62 for grinding processing. During the grinding process, when grinding is advanced, the sound insulation board 53 is advanced in the sound insulation groove 52. After the grinding process, the advancing processing seat 3 drives the first sound insulation cover 5 to retreat and reset, and the first sound insulation cover 5 is separated from the second sound insulation cover 51. The solenoid valve 83 is closed, and the driving mechanism drives the fixed processing seat 2 to rotate. The fasteners after grinding are rotated to one side of the grinding seat 6, and the fasteners are taken away from the three-jaw chuck 21. Repeat the operation, and during the grinding process, the feeding and discharging operations are carried out on the fixed processing seat 2 synchronously. During the grinding process, under the action of the water pump 10, the water in the water storage tank 14 in the processing machine base 1 is cooled and conveyed to the spray head 8 through the connecting pipe 9 passing through the cold water pipe of the cooling box 12, and the spray head 8 sprays water for grinding on the grinding head 63 and the fasteners.And when the induction sound insulation cover is closed, atomization is carried out inside the sound insulation cover through the atomization pipe 81 and the atomization nozzle 82, and water is sprayed to cool the grinding head 63 and the grinding part of the fastener inside the sound insulation cover and for induction atomization dust reduction. The sound insulation cover prevents water from splashing, and the generated waste water is filtered by the filter screen 15 in the water collecting tank 13 and stored in the water storage tank 14, realizing the collection, filtration and cyclic supply of grinding water spraying, with good energy saving performance. During the process of grinding propulsion, the connecting plate 16 and the cleaning brush 17 at the bottom of the propulsion processing seat 3 move in the water collecting tank 13, and the cleaning brush 17 cleans the passing filter screen 15, cleaning the filter screen 15 during the propulsion grinding. The filter screen 15 has smooth filtration and is convenient to clean. In the present invention, by installing the first sound insulation cover 5 and the second sound insulation cover 51 on the grinding equipment, the first sound insulation cover 5 is closed with the second sound insulation cover 51 as the propulsion processing seat 3 grinds and advances. The closed sound insulation is good, and the sound insulation cover does not interfere with the grinding processing operation of the fastener. Moreover, the first sound insulation cover 5 and the second sound insulation cover 51 are made by compounding a galvanized steel plate 54, a stainless steel plate 55, a skeleton 56, a sound insulation honeycomb layer 57, a sound insulation layer 58 and a sound absorption layer 59. The sound insulation cover has good structural strength and sound insulation and sound absorption performance.,
