Description

Technical Field

[0001] The invention relates to the technical field of grinding disc cooling mechanism equipment, in particular to a grinding disc cooling mechanism of a chip grinder and a cooling method thereof. Background Art

[0002] The cooling mechanism usually adopts a circulating water cooling system, cooling fan, heat sink, etc., which dissipates the heat of the grinding disc by conveying cooling medium or using air to help eliminate the heat generated during the grinding process, thereby keeping the grinding disc working within an appropriate temperature range. This can effectively extend the service life of the equipment, improve production efficiency, and ensure the chip processing quality; the grinding disc cooling mechanism of the chip grinder mainly functions to reduce the temperature of the grinding disc. During the chip grinding process, the grinding disc will generate a lot of heat due to friction and processing. If the temperature of the grinding disc is too high, it will cause uneven chip grinding, reduced equipment performance, and even damage to the chip; therefore, effective cooling of the grinding disc by the cooling mechanism can maintain the stability of the grinding process and ensure the chip processing quality and the normal operation of the equipment.

[0003] Under the existing technology, the grinding disc and the base for placing the chip in the grinder are mostly placed horizontally. The horizontal placement will cause the coolant to flow slowly between the grinding disc and the chip, making it difficult for the water coolant to quickly take away the heat of the grinding disc. A large amount of grinding debris will be retained between the grinding disc and the chip for a long time, which will reduce the grinding quality of the grinding disc on the one hand, and on the other hand, a large amount of grinding debris may scratch the surface of the chip, thereby reducing the grinding quality of the chip.

[0014] The cooling method of the grinding disc cooling mechanism of the chip grinder comprises the following steps:

[0015] S1: Install and fix the chip body. First, press the chip body inside the grinding base;

[0016] S2: grinding the chip body, driving a plurality of grinding bases on the rotating shaft through the rotating frame, and then cooperating with the grinding head to rotate, grinding a plurality of chip bodies on the grinding base;

[0017] S3: Cooling the grinding head, connecting the cooling liquid through an external water pipe, and conveying the cooling liquid to the cooling tank on the grinding base through the water cavity;

[0018] S4: adjusting the coolant discharge speed, blocking the water cavity by the centrifugal block, adjusting the position of the centrifugal block inside the tapered hole according to the rotation speed of the rotating frame, thereby adjusting the cross-sectional area of ​​the water cavity.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention sets a grinding cooling mechanism to connect the external coolant conveyor to the external water pipe. At this time, the coolant enters the sealing ring through the external water pipe. The sealing ring can prevent the coolant from leaking at the connection between the rotating frame in rotation and the stationary external water pipe, thereby ensuring the reliability of the cooling device. The coolant enters the grinding base through the water cavity, and then flows evenly to the cooling tank through the water outlet at the bottom of the cooling tank. At this time, the coolant in the cooling tank intersects with the grinding head. This arrangement can fully cool the grinding head on the one hand, and on the other hand, the grinding debris trapped between the grinding head and the chip body can be discharged through the cooling tank. A large amount of grinding debris may scratch the chip surface. Discharging the grinding debris through the cooling tank is beneficial to improving the grinding quality of the grinding head.

[0021] (2) The present invention sets a locking mechanism, which can fix the chip body on the airbag ring by pressing. At this time, the chip body is located inside the grinding base. When the grinding base rotates to the vicinity of the grinding head, the extrusion ring and the extrusion block are squeezed. The extrusion ring is squeezed and moves toward one end of the grinding head. At this time, the extrusion ring pushes the extrusion rod to squeeze the pushing plate. The pushing plate pushes the chip body to contact the grinding head. When the extrusion ring is away from the extrusion block, under the action of the extrusion spring, the extrusion rod drives the piston rod to move toward one end of the extrusion ring. The piston rod drives the piston plate to squeeze the air inside the inflation cylinder. At this time, the gas inside the inflation cylinder enters the airbag ring through the hose. At this time, the airbag ring clamps the chip body more stably. This arrangement can prevent the vertically placed chip body from falling off.

[0022] (3) The present invention sets a coolant switch mechanism. When the grinding base rotates to the vicinity of the grinding head, the extrusion ring and the extrusion block are squeezed. The extrusion ring is squeezed and moves toward one end of the grinding head. At this time, the extrusion ring pushes the extrusion rod to move toward one end of the chip body. The extrusion rod drives the rack to move. The rack drives the switch gear to rotate. The rotation of the switch gear causes the blocking plate to rotate. At this time, the rotation of the blocking plate can keep the sealed water cavity unobstructed, thereby controlling the discharge of coolant in the water cavity. The water cavity near the grinding head is controlled to remain unobstructed, while the water cavities at other positions remain closed. This can save coolant and avoid waste of coolant.

[0023] (4) The present invention provides a coolant regulating mechanism, in which the centrifugal block can move according to the rotation speed of the rotating frame. When the rotation speed of the rotating frame is higher, the displacement caused by the centrifugal block squeezing the reset spring is larger. When the displacement of the centrifugal block is larger, the cross-sectional area of ​​the coolant passing through the conical hole is larger. The larger the area through which the coolant flows, the larger the flow rate of the coolant. When the grinding speed is faster, the more heat is generated. This arrangement makes the heat dissipation effect at different grinding speeds optimal.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

This arrangement can fully cool the grinding head 22 on the one hand, and on the other hand, the grinding debris trapped between the grinding head 22 and the chip body 206 can be discharged through the cooling groove 304. A large amount of grinding debris may scratch the chip surface, and discharging the grinding debris through the cooling groove 304 is beneficial to improving the grinding quality of the grinding head 22.

[0054] A specific application of this embodiment is:

[0055] First, the chip body 206 is pressed inside the grinding base 203, and the driving motor 15 is started at this time. The output end of the driving motor 15 rotates to drive the output shaft 16 to rotate, and the output shaft 16 rotates to drive the rotating frame 201 to rotate. The rotating frame 201 rotates to drive the grinding base 203 on the rotating shaft 202 to rotate, and the grinding base 203 rotates to drive the chip body 206 inside the grinding base 203 to rotate. At the same time, the output shaft 16 rotates to drive the gear 17 to rotate, and the gear 17 rotates to drive the gear 2 18 to rotate. The gear 2 18 rotates to drive the transmission belt 20 on the transmission shaft 19 to rotate, and the transmission belt 20 rotates to drive the grinding head 22 on the grinding shaft 21 to rotate, and the grinding head 22 fits the surface of the grinding base 203. This arrangement is conducive to the grinding head 22 to uniformly grind the chip body 206 on the grinding base 203. In the present invention, multiple groups of grinding bases 203 are arranged to contact the grinding head 22 alternately, so that the surface of the chip body 206 being ground has the opportunity to contact the air, so that the chip temperature is reduced, thereby maintaining It ensures that the temperature of the chip will not continue to rise, thereby ensuring that the product chip will not be damaged due to long-term high-temperature grinding; by setting up the grinding cooling mechanism 3, the external coolant conveyor is connected to the external water pipe 301, and the coolant enters the sealing ring 302 through the external water pipe 301. By setting the sealing ring 302, it can prevent the coolant from leaking at the connection between the rotating rotating frame 201 in rotation and the external water pipe 301 in stillness, thereby ensuring the reliability of the cooling device. The coolant enters the grinding base 203 through the water cavity 303, and then flows evenly to the cooling groove 304 through the water outlet 305 at the bottom of the cooling groove 304. At this time, the coolant in the cooling groove 304 intersects with the grinding head 22. This setting can fully cool the grinding head 22 on the one hand, and on the other hand, the grinding debris trapped between the grinding head 22 and the chip body 206 can be discharged through the cooling groove 304. A large amount of grinding debris may scratch the chip surface. Discharging the grinding debris through the cooling groove 304 is beneficial to improving the grinding quality of the grinding head 22;

[0056] By setting a locking mechanism 4, the chip body 206 is fixed on the airbag ring 409 by pressing. At this time, the chip body 206 is located inside the grinding base 203. When the grinding base 203 rotates to the vicinity of the grinding head 22, the extrusion ring 403 and the extrusion block 410 are extruded. The extrusion ring 403 is extruded and moves toward one end of the grinding head 22. At this time, the extrusion ring 403 pushes the extrusion rod 402 to squeeze the push sheet 401, and the push sheet 401 pushes the chip body 206 to contact the grinding head 22. When the extrusion ring 403 is away from the extrusion block 410, under the action of the extrusion spring 404, the chip body 206 is pressed. When the extrusion rod 402 is used, the piston rod 405 moves toward one end of the extrusion ring 403, and the piston rod 405 drives the piston plate 407 to squeeze the air inside the inflation cylinder 406. At this time, the gas inside the inflation cylinder 406 enters the air bag ring 409 through the hose 408. At this time, the air bag ring 409 clamps the chip body 206 more stably. This setting can prevent the vertically placed chip body 206 from falling off; by setting the coolant switch mechanism 5, when the grinding base 203 rotates to the vicinity of the grinding head 22, the extrusion ring 403 and the extrusion block 410 are squeezed, and the extrusion ring 403 is squeezed and moves toward one end of the grinding head 22. At this time, the squeezing ring 403 pushes the squeezing rod 402 to move toward one end of the chip body 206. The squeezing rod 402 drives the rack 501 to move. The rack 501 drives the switch gear 502 to rotate. The switch gear 502 rotates to rotate the blocking plate 503. At this time, the rotation of the blocking plate 503 can keep the sealed water cavity 303 unobstructed, thereby controlling the discharge of the coolant in the water cavity 303, controlling the water cavity 303 near the grinding head 22 to remain unobstructed, and keeping the water cavity 303 at other positions closed, which can save energy. Coolant is used to avoid waste of coolant; by setting a coolant regulating mechanism 6, the centrifugal block 601 in the coolant regulating mechanism 6 can move according to the rotation speed of the rotating frame 201. When the rotation speed of the rotating frame 201 is higher, the displacement generated by the centrifugal block 601 squeezing the return spring 603 is larger. When the displacement of the centrifugal block 601 is larger, the cross-sectional area of ​​the coolant passing through the conical hole 602 is larger. The larger the area flowing through the coolant is, the larger the flow rate of the coolant is. When the grinding speed is faster, the more heat is generated. This arrangement makes the heat dissipation effect at different grinding speeds reach the best.
