Description

Technical Field

[0002] In the CNC machining process of cemented carbide inserts, effective spraying and management of coolant are crucial to ensuring machining accuracy, extending tool life and improving production efficiency. Existing cemented carbide insert processing devices usually use an external coolant spraying system to reduce the heat generated during the machining process and prevent the tool from overheating and causing wear, thermal deformation or even damage. Traditional coolant spraying systems mostly rely on independent spraying equipment, usually spraying coolant directly onto the tool surface through a nozzle. This process requires additional equipment and manual intervention to adjust the spraying amount and spraying timing. However, existing coolant spraying systems often have some limitations: on the one hand, it is difficult to accurately control the spraying amount and spraying timing of the coolant by manual operation, which can easily lead to uneven spraying, waste or untimely cooling of the coolant, thus affecting the machining effect.

[0003] In addition, the coolant in traditional systems often needs to be processed through external discharge or recovery systems, and the iron filings and impurities in the coolant cannot be separated efficiently, resulting in waste and frequent replacement of coolant, increasing the cost of use and maintenance workload.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0030] Please refer to the attached Figure 1 - Attachment Figure 8The embodiment of the present invention provides a CNC machining device for a cemented carbide insert, comprising a mounting base plate 1 and a mounting column 10. A collection box 2 is mounted at the middle of the top of the mounting base plate 1. A first motor 4 is mounted on the outside of the collection box 2. A transmission shaft 5 is fixedly connected to the output end of the first motor 4. A grinding wheel 3 is fixedly connected to the outside of the transmission shaft 5. One end of the transmission shaft 5 passes through the outside of the collection box 2 and is fixedly connected to two sector gears 6. Two fixed columns 7 are fixedly connected to the outside of the collection box 2. A rack plate 8 is slidably connected to the top of the fixed column 7. One end of the rack plate 8 is fixedly connected to the outside of the collection box 2. A movable column 9 is fixedly connected to the side, and a rubber piston 33 is fixedly connected to one end of the movable column 9. The rubber piston 33 is slidably connected to the inside of the mounting column 10. The inner cavity of the mounting column 10 is connected to the first connecting pipe 11 and the second connecting pipe 12 in sequence. When the first motor 4 drives the sector gear 6 to rotate, the two sector gears 6 will intermittently mesh with the rack plate 8, thereby driving the rubber piston 33 to reciprocate along the inside of the mounting column 10, so that a suction force is generated inside the mounting column 10, and the coolant inside the collection box 2 is sprayed onto the outer surface of the alloy blade to be processed.

[0031] Specifically, when the first motor 4 is started and drives the transmission shaft 15 to rotate, the transmission shaft 15 drives the two sector gears 6 to rotate. Since the two sector gears 6 are arranged in an intricate manner and are intermittently meshed with the rack plate 8, when one of the sector gears 6 is meshed with the rack plate 8, it will drive the rack plate 8 to move in one direction. When the other sector gear 6 is meshed with the rack plate 8, it will drive the rack plate 8 to move along a trajectory opposite to the first movement direction, thereby ensuring the reciprocating movement of the rubber piston 33. The movement of the rubber piston 33 will affect the liquid state inside the mounting column 10. When the movable column 9 moves to the left, the rubber piston 33 drives the coolant to enter the mounting column 10 through the second connecting pipe 12, thereby forming a negative pressure in the mounting column 10. After the liquid enters the mounting column 10 through the second connecting pipe 12, the negative pressure state formed causes the coolant in the first connecting pipe 11 to be attracted and ejected, and sprayed onto the outer surface of the blade for cooling. Through the action of two one-way valves, the coolant can only flow in one direction, avoiding the problem of coolant backflow and ensuring the stability of the coolant and precise control of the flow rate. The entire process realizes the automatic spraying of the coolant and the synchronous control of the grinding process. This structural design can effectively control the flow and spraying position of the coolant, ensuring that the coolant evenly covers the blade surface, thereby improving the cooling effect and processing accuracy.

[0032] A mounting frame 16 is mounted on one side of the top of the mounting base plate 1, a second motor 17 is mounted on the top of the mounting frame 16, a driving screw 18 is fixedly connected to the driving end of the second motor 17, a threaded frame 15 is threadedly connected to the outer side of the driving screw 18, an electric clamp 14 is mounted on the outer side of the threaded frame 15, and the electric clamp 14 is used to clamp the blade. A guide rod 19 is slidably connected to a through hole on one side of the inner side of the threaded frame 15, and the upper and lower ends of the guide rod 19 are fixedly connected to the inner side of the mounting frame 16.

[0033] Specifically, first, the blade to be sharpened is clamped by the electric clamp 14. The electric clamp 14 automatically opens and clamps the blade edge according to the control signal to ensure that the blade will not loosen or slip during the processing. The clamping action of the electric clamp 14 is controlled by a motor or a pneumatic device, which can ensure the clamping force and accuracy and adapt to blades of different shapes and sizes. When the electric clamp 14 successfully clamps the blade, the second motor 17 starts to work. The second motor 17 drives the driving screw 18 to rotate through the driving end, and the rotation of the driving screw 18 is connected to the threaded frame 15 through the thread on its outer side, so that the threaded frame 15 moves up and down along the outer wall of the driving screw 18. Driven by the driving screw 18, the threaded frame 15 moves up and down along the trajectory of the thread. This up and down movement is very stable, because the threaded frame 15 is provided with a guide rod 19. With the help of the guide rod 19, the threaded frame 15 can stably slide in the vertical direction to avoid offset or jamming. The up and down movement of the threaded frame 15 causes the electric clamp 14 clamping the blade to move synchronously.

[0034] By moving the electric clamp 14, the clamped blade is accurately brought into the grinding groove 13 outside the grinding wheel 3. The contact position between the blade edge and the grinding wheel 3 can be accurately controlled by adjusting the rotation of the driving screw 18. At this time, after the blade edge enters the grinding groove 13, the precise grinding process can be started to ensure the uniformity and accuracy of the blade grinding.

[0035] The whole process can be precisely adjusted by the controller 22, and the speed of the second motor 17, the up and down movement distance of the threaded rack 15 and the clamping force of the electric clamp 14 can be adjusted according to actual needs. The control system usually includes a liquid crystal display, operation buttons and sensors, which can monitor the equipment status in real time and make feedback adjustments.

[0036] A separation assembly is installed inside the collection box 2, and the separation assembly is used to centrifugally separate iron filings and coolant. The separation assembly includes a rotating column 27, the bottom end of the rotating column 27 is movably connected to the inner bottom wall of the collection box 2 through a bearing, and the top end of the rotating column 27 is fixedly connected to a rotating barrel 32, and the bottom of the rotating barrel 32 is connected to a drain pipe 31. A filter is arranged inside the drain pipe 31, and the filter is used to prevent iron filings from entering the interior of the collection box 2 through the drain pipe 31. It also includes two synchronous wheels 21 and a bevel gear 1 28, one of which is fixedly connected to the driving end of the first motor 4, and the two synchronous wheels 21 are connected by a belt 26, and the outer side of the other synchronous wheel 21 is fixedly connected to a transmission shaft 2 30, and one end of the transmission shaft 2 30 is fixedly connected to a bevel gear 2 29, and the bevel gear 1 28 is fixedly connected to the outer bottom end of the rotating column 27, and the outer side of the bevel gear 1 28 is meshed with the outer side of the bevel gear 29. The mounting column 10 is fixedly connected to the outer side of the collecting box 2 , and one end of the second connecting pipe 12 is connected to the inner side of the collecting box 2 .

[0037] Specifically, when the first motor 4 is started, its output end drives the upper synchronous wheel 21 to rotate. The synchronous wheel 21 is connected to the lower synchronous wheel 21 through the belt 26, so that the lower synchronous wheel 21 rotates synchronously. The rotation of the lower synchronous wheel 21 transmits power through the fixedly connected transmission shaft 2 30, further driving the bevel gear 2 29 to rotate. The bevel gear 2 29 meshes with the bevel gear 1 28, and the rotation of the bevel gear 1 28 drives the rotating column 27 to rotate. The rotation of the rotating column 27 drives the rotating barrel 32 to rotate

[0038] When the rotating barrel 32 rotates, since the materials inside the rotating barrel 32, such as coolant and iron filings, have inertia, the centrifugal force will push these materials toward the inner wall of the barrel. Specifically, the magnitude of the centrifugal force is proportional to the rotation speed of the rotating barrel 32, the density of the materials, and their distance from the rotation axis, that is, the radius of the materials from the rotation axis. Therefore, the faster the rotating barrel 32 rotates, the greater the centrifugal force generated, and the iron filings and coolant will be quickly thrown toward the inner wall of the barrel. In the rotating barrel 32, the density of the iron filings is usually greater than the density of the coolant, so under the action of the centrifugal force, the iron filings will be thrown toward the inner wall of the barrel, while the coolant is relatively light and is mainly concentrated in the central area of ​​the barrel. This process takes advantage of the different densities of the iron filings and the coolant.

[0039] Due to their large mass and density, the iron filings tend to move toward the inner wall of the barrel under the action of centrifugal force and eventually adhere to the inner wall. The coolant, due to its low density, will be pushed to the periphery of the barrel. At the same time, because it is light, it will maintain fluidity and be discharged through the drain pipe 31 under the push of centrifugal force.

[0040] When the iron chips inside the rotating barrel 32 accumulate to a certain extent, the magnetic iron chip collector absorbs the iron chips through a strong magnetic field to prevent the iron chips from contaminating the coolant or affecting the operation of the equipment. The iron chip collector can automatically separate the iron chips from the system to ensure the cleanliness of the coolant and the efficient operation of the system.

[0041] Embodiment 2:

[0042] In order to solve the problem that the collection box 2 cannot be replenished in time, the following technical solution is now proposed:

[0043] A storage box 20 is fixedly connected to one side of the top of the installation base plate 1, a pump body 24 is installed on one side of the top of the storage box 20, a first connecting pipe 23 is fixedly connected to the output end of the pump body 24, a second connecting pipe 25 is fixedly connected to the input end of the pump body 24, one end of the second connecting pipe 25 is connected to the outside of the storage box 20, one end of the first connecting pipe 23 is connected to the inside of the collection box 2, and a liquid level sensor 34 is fixedly connected to the inside of the installation base plate 1. A controller 22 is installed on the top of the storage box 20, and the controller 22 is electrically connected to the liquid level sensor 34.

[0044] Specifically, the storage tank 20 is a container for storing spare coolant, and its design takes into account the capacity and the requirements for easy connection with other components. The liquid level sensor 34 is used to monitor the liquid level of the coolant inside the collection tank 2. The liquid level sensor 34 can monitor the level of the coolant in real time by sensing the change in the liquid level of the coolant in the collection tank 2, and determine whether it is lower than the preset minimum liquid level. When the liquid level sensor 34 detects that the amount of coolant in the collection tank 2 is too little, it will send a signal to the controller 22, and the controller 22 controls the start of the pump body 24 according to the signal. The controller 22 and the liquid level sensor 34 are electrically connected to ensure that the system can automatically start the replenishment program when the coolant is insufficient.

[0045] During the operation of the system, when the liquid level sensor 34 detects that the amount of coolant in the collection tank 2 is too low, the liquid level sensor 34 will transmit a detection signal to the controller 22. After receiving the signal, the controller 22 will send a start signal to activate the pump body 24. After the pump body 24 starts to operate, the coolant in the storage tank 20 is sucked through the second connecting pipe 25 and transported to the collection tank 2 through the first connecting pipe 23 to complete the replenishment of the coolant. In this way, the liquid level of the coolant in the collection tank 2 can be automatically and accurately maintained, thereby avoiding the reduction of processing accuracy or equipment damage due to insufficient coolant.

[0046] The advantage of this replenishment system is that it can realize automatic replenishment of coolant, avoiding the trouble of frequent manual inspection and replenishment of coolant, and improving the working efficiency of the system. The cooperation of the liquid level sensor 34 and the controller 22 makes the replenishment process of coolant more intelligent and automated. In addition, the structural design of the system is simple and reliable, which can ensure a continuous and stable supply of coolant during the processing process, effectively ensuring the processing quality and long-term stable operation of the equipment.

[0047] Working principle: When the device is used, the blade to be sharpened is first clamped by the electric clamp 14, and then the second motor 17 is started to drive the driving screw 18 to rotate, so that the threaded frame 15 is further moved up and down along the outer wall of the driving screw 18, and the electric clamp 14 is further driven to move synchronously, and the blade of the clamped blade is moved to the grinding groove 13 outside the grinding wheel 3. At this time, the first motor 4 is started to drive the transmission shaft 5 to rotate, so that the grinding wheel 3 is further driven to rotate to grind the blade;

[0048] When the transmission shaft 15 rotates, it will drive the two sector gears 6 to rotate synchronously. At this time, the two sector gears 6 are intermittently meshed with the rack plate 8, and the rack plate 8 is driven to move left and right along the top of the fixed column 7. When the rack plate 8 moves to the left, it drives the movable column 9 to move synchronously. The movement of the movable column 9 will drive the rubber piston 33 to move synchronously. At this time, the interior of the installation column 10 is in a negative pressure state, and the coolant inside the collection box 2 enters the interior of the installation column 10 through the second connecting pipe 12. When the rubber piston 33 moves downward, the internal coolant of the installation column 10 will be sprayed to the outer surface of the blade through the first connecting pipe 11, thus realizing the synchronous and precise automatic operation of the coolant spraying and grinding process. This automated spraying method can ensure that the coolant is evenly covered on the surface of the blade, making the cooling effect more efficient and stable;

[0049] In addition, when the output end of the first motor 4 rotates, it drives the upper synchronous wheel 21 to rotate, and under the connection of the belt 26, drives the lower synchronous wheel 21 to rotate, thereby driving the transmission shaft 2 30 to rotate synchronously, further rotating the bevel gear 2 29, and the bevel gear 29 drives the meshing bevel gear 1 28 to rotate, further driving the rotating column 27 to rotate, and at this time drives the rotating barrel 32 to rotate. At this time, the coolant in the rotating barrel 32 is discharged through the drain pipe 31, and the iron filings in the rotating barrel 32 are thrown onto the inner wall. When there are too many iron filings, they are collected by a magnetic iron filing collector;

[0050] In addition, when the liquid level sensor 34 detects that the amount of coolant inside the collection box 2 is too little, the liquid level sensor 34 will send a signal to the controller 22, and the controller 22 will send a signal to start the pump body 24, so that the coolant inside the storage box 20 is discharged into the first connecting pipe 23 through the second connecting pipe 25, and then discharged into the interior of the collection box 2 through the first connecting pipe 23 to replenish the coolant.

[0051] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
