Description

Technical Field

[0001] The present application relates to the field of milling cutter processing, and in particular to a milling cutter grinding device and a forming process. Background Art

[0002] A milling cutter is a rotary tool with one or more teeth used for milling. Each tooth cuts off the excess of the workpiece intermittently in sequence during operation. Milling cutters are mainly used to process planes, steps, grooves, forming surfaces and cut off workpieces on milling machines.

[0003] The related technology discloses a milling cutter grinding device, including a base, on which are arranged a workpiece clamping portion, a cutting device, a conveying device and a cooling device. The workpiece clamping portion is used to fix the workpiece and drive the workpiece to rotate, the cutting device is used to cut the workpiece, and the conveying device is used to convey the processed workpiece. The cutting device includes two cutting wheels, and the cutting directions of the two cutting wheels are perpendicular to each other, so that the cutting wheels can cut milling grooves in different directions on the workpiece. The cooling device includes a cooling pipe, a coolant tank and a water pump. The water pump pumps the coolant in the coolant tank into the cooling pipe so that the end of the cooling pipe is facing the position of the workpiece. The water pump is used to continuously flush the workpiece with the coolant, thereby cooling the workpiece.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when the grinding device is used to cut the workpiece, the water pump is working continuously and the coolant is continuously pumped out, but during the transportation of the workpiece, the coolant is not flushed on the workpiece, which causes a waste of coolant and increases processing costs. Summary of the invention

[0005] In order to reduce the waste of coolant, the present application provides a milling cutter grinding device and a forming process.

[0006] In a first aspect, the present application provides a milling cutter grinding device, which adopts the following technical solution:

[0007] A milling cutter grinding device comprises a base, on which a clamping device, a cutting device and a transport device are arranged, the clamping device is used to clamp a workpiece, the cutting device is used to cut the workpiece, and the transport device is used to transport the workpiece. The device also comprises a cooling device, the cooling device comprises a coolant tank, a water pump and a cooling pipe, the water pump is located in the coolant tank, one end of the cooling pipe is connected to the water source output end of the water pump, and the other end is located near the workpiece, the cooling pipe is a universal pipe, the coolant tank is provided with a connecting bucket, the connecting bucket is connected to the coolant tank, the coolant tank is provided with a rotating assembly, and the rotating assembly is used to rotate the end of the cooling pipe to the connecting bucket.

[0008] By adopting the above technical scheme, when the grinding device is used to process the workpiece into a milling cutter, the transport device first transports the workpiece to the position of the clamping device, the clamping device clamps and fixes the workpiece, and then the cutting device cuts the workpiece and processes the workpiece into a milling cutter. During the processing, the water pump pumps the coolant in the coolant tank into the cooling pipe, and the other end of the cooling pipe is located close to the workpiece, so that the coolant can flush and cool the workpiece to ensure normal processing of the workpiece. After the workpiece processing is completed, the transport device will move the processed workpiece away. At this time, the rotating component is started, and the cooling pipe is driven by the rotating component to rotate, so that the end of the cooling pipe is rotated to the connecting bucket, and the coolant will flow into the coolant tank through the connecting bucket instead of being wasted, thereby reducing the waste of coolant. When processing the next workpiece, it is only necessary to turn the cooling pipe back.

[0009] Optionally, the rotating assembly includes a rotating block arranged on the coolant tank, the rotating block is provided with a vertical rod, the vertical rod is arranged in a vertical direction, a first connecting rod and a second connecting rod are arranged on the end of the vertical rod away from the rotating block, the first connecting rod and the second connecting rod are both fixedly connected to the cooling pipe, and a driving assembly for driving the rotating block to rotate reciprocally is provided on the coolant tank.

[0010] By adopting the above technical solution, the driving component is started, and the driving component will drive the rotating block to rotate, and the rotating block drives the vertical rod to rotate, and the vertical rod then drives the first connecting rod and the second connecting rod to rotate. Since the first connecting rod and the second connecting rod are both fixedly connected to the cooling pipe, and the cooling pipe is a universal tube, the first connecting rod and the second connecting rod will drive the cooling pipe body to rotate, so that the end of the cooling pipe moves, thereby realizing the rotation of the cooling pipe.

[0011] Optionally, the driving assembly includes an electric cylinder arranged on the coolant tank, an abutment rod is arranged on the driving end of the electric cylinder, the abutment rod extends in a horizontal direction, a rack is arranged on the abutment rod along the length direction of the abutment rod, a gear is arranged on the rotating block along the circumference of the rotating block, and the rack and the gear are meshed with each other.

[0012] By adopting the above technical solution, the electric cylinder is started, and the driving end of the electric cylinder drives the abutment rod to move in the horizontal direction. At this time, since the rack on the abutment rod is meshed with the gear on the rotating block, the abutment rod will drive the gear to rotate, so that the rotating block can drive the vertical rod and the first connecting rod and the second connecting rod to rotate.

[0013] Optionally, the clamping device includes a fixed block, on which a clamping tube is arranged, one end of the clamping tube is open and the other end is closed, the inner diameter of the clamping tube is adapted to the diameter of the workpiece, a pressure sensor is arranged inside the clamping tube and at a position located at the closed end of the clamping tube, a controller is arranged on the base, the pressure sensor is electrically connected to the controller, and the controller is used to control the extension and retraction of the electric cylinder.

[0014] By adopting the above technical solution, after the workpiece is loaded into the clamping tube, the workpiece will generate pressure on the pressure sensor in the clamping tube, so that the pressure sensor generates a signal and transmits it to the controller. After receiving the signal, the controller controls the electric cylinder to start, and the electric cylinder drives the abutment rod to move, so that the rotating block rotates, thereby causing the cooling tube to rotate to a position facing the workpiece. After the processed workpiece is taken out of the clamping tube, the pressure sensor stops sending signals, and the controller controls the cylinder to start, so that the abutment rod moves back, and the cooling tube rotates to a position facing the connecting bucket. In this way, the automatic rotation of the cooling tube is realized, making the use of the grinding device more convenient.

[0015] Optionally, a limiting member for limiting the displacement of the abutment rod is provided on the coolant tank and at the position of the abutment rod.

[0016] By adopting the above technical solution, the setting of the limiter can control the moving distance of the abutment rod, so that the abutment rod drives the cooling tube to rotate a certain angle. At the same time, the limiter can also prevent the rack on the abutment rod from being separated from the gear.

[0017] Optionally, the limiting member includes a first limiting block and a second limiting block arranged on the coolant tank, the first limiting block and the second limiting block both have limiting holes, the abutment rod is passed through the limiting hole and is arranged between the first limiting block and the second limiting block, and the abutment rod is provided with a first blocking block and a second blocking block at both ends of the rack.

[0018] By adopting the above technical solution, when the abutment rod moves, the abutment rod will drive the first blocking block and the second blocking block to move. When the first blocking block abuts against the first limit block or the second blocking block abuts against the second limit block, the first blocking block or the second blocking block will prevent the abutment rod from continuing to move, thereby achieving control of the moving distance of the abutment rod.

[0019] Optionally, a recovery box is provided on the base and below the cutting device, and a recovery device for recovering iron filings is provided in the recovery box.

[0020] By adopting the above technical solution, the iron filings washed down by the coolant can be recovered by using the recovery box and the recovery device, so as to be recycled. Meanwhile, the recovery box also serves as a device for recovering the coolant, thereby further reducing the waste of the coolant.

[0021] Optionally, the recycling device includes an electromagnet plate disposed in the recycling box, the electromagnet plate abuts against an inner wall of one side of the recycling box, and the electromagnet plate is rotatably connected to the recycling box.

[0022] By adopting the above technical solution, when the grinding device is working, the electromagnet plate is energized, the electromagnet plate will generate magnetism and absorb iron filings in the coolant. When recycling is needed, the electromagnet plate is rotated to move the electromagnet plate out of the recycling box, which is very convenient.

[0023] In a second aspect, the present application provides a milling cutter forming process, which adopts the following technical solution:

[0028] S4: When the next workpiece is to be processed, the rotating assembly rotates the coolant pipe to the position of the clamping device and cools the workpiece;

[0029] S5: Repeat S1-S4 to continuously process the workpiece.

[0030] By adopting the above technical solution, during the process of processing the workpiece, the rotation of the cooling pipe is realized by using the rotating component, which can reduce the waste of coolant and thus save the processing cost.

[0031] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] 1. By arranging a connecting bucket and a rotating assembly on the coolant tank, the rotating assembly is used to drive the end of the cooling pipe to rotate to a position facing the connecting bucket, so that during the transportation of the workpiece, the coolant can flow back into the coolant tank through the connecting bucket, thereby reducing the waste of coolant;

[0042] Reference Figure 2 and Figure 3The grinding device also includes a cooling device 5, which includes a coolant tank 51, a water pump and a cooling pipe 52. The coolant tank 51 is fixedly connected to one side of the base 1, and the water pump is located in the coolant tank. One end of the cooling pipe 52 is connected to the water source output end of the water pump, and the other end is located near the workpiece. The water pump pumps the coolant into the cooling pipe 52, and the coolant is sprayed from the cooling pipe 52 to cool the workpiece. The cooling pipe 52 is a universal pipe. By adjusting the position of the cooling pipe 52, the direction of the end of the cooling pipe 52 can be changed. The coolant tank 51 is provided with a connecting bucket 511 connected to the coolant tank 51, and a rotating component 6 is provided on the coolant tank 51. The rotating component 6 can rotate the end of the cooling pipe 52 to the connecting bucket 511.

[0043] When using the grinding device, the transport device 4 transports the workpiece into the clamping tube 22 and fixes it, and then uses the first cutting wheel 31 and the second cutting wheel 32 to process the workpiece. During the processing, the cooling tube 52 will spray coolant to cool the workpiece. After the processing is completed, the transport device 4 takes the workpiece out of the clamping tube 22, and then starts the rotating component 6, and uses the rotating component 6 to rotate the cooling tube 52 and move the end of the cooling tube 52 to the position of the connecting bucket 511. At this time, the coolant will flow back into the coolant tank 51, thereby reducing the waste of coolant.

After the workpiece is placed in the clamping tube 22, the workpiece generates pressure on the pressure sensor, and the pressure sensor generates a signal transmitted to the controller, so that the controller controls the electric cylinder 631 to extend or retract, thereby realizing the rotation of the cooling tube 52.

[0046] After starting the cylinder, the cylinder drives the abutment rod 632 to move in the horizontal direction. At this time, since the rack 6321 on the abutment rod 632 is meshed with the gear 611 on the rotating block 61, the movement of the abutment rod 632 will cause the gear 611 to rotate, thereby driving the rotating block 61 to rotate, and then the rotating block 61 drives the vertical rod 62 to rotate, and the vertical rod 62 drives the first connecting rod 621 and the second connecting rod 622 to rotate, so that the cooling tube 52 rotates.
