Description

Technical Field

[0001] This invention belongs to the technical field of milling cutter cutting, and relates to a cutting device for milling cutter production and processing. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used in milling operations. During operation, the milling cutter sequentially and intermittently removes excess material from the workpiece using each cutting tooth. Milling cutters are primarily used on milling machines to machine planes, steps, grooves, shaped surfaces, and to cut off workpieces. The process of machining with a milling cutter involves manually adding unworked bar stock to the machine tool and then performing the cutting operation to shape the bar stock into the milling cutter workpiece.

[0003] Currently, when adding bar stock to the machine tool, it is necessary to manually hold the bar stock for loading. In the process of batch milling, the bar stock needs to be manually loaded each time, and after the cutting is completed, the milling cutter also needs to be manually removed. The operation process is quite cumbersome, and during the removal process, the workers directly contact the freshly processed workpiece, which can easily cause hand cuts and poses certain safety hazards. Summary of the Invention

[0004] In view of this, the present invention provides a cutting device for milling cutter production.

The machine tool is equipped with a dual-axis moving system, on which a cutting head is mounted. A clamping frame is mounted in the lower part of the machine tool, and a cylinder is mounted on one side of the clamping frame. A pusher plate is rotatably connected to the telescopic rod of the cylinder. A drive motor is mounted on the machine tool, and a rotary shaft is rotatably connected to the output shaft of the drive motor. The rotary shaft is rotatably connected to the clamping frame. The clamping frame is provided with a blanking mechanism and a clamping mechanism. The blanking mechanism is used to add milling cutter raw materials.

[0006] Furthermore, the feeding mechanism includes an electric push rod, a blocking plate, and a feeding plate. The electric push rod is mounted on the clamping frame, and the feeding plate is connected to the lower part of the clamping frame. The feeding plate is inclined and has a receiving groove. The blocking plate is connected to the telescopic rod of the electric push rod.

[0007] Furthermore, the clamping mechanism includes a lower pressure frame, an elastic element, and a swing rod. The lower pressure frame is slidably connected to the upper part of the clamping frame, and an elastic element is connected between the lower pressure frame and the clamping frame. The swing rod is rotatably connected to the clamping frame, with the front side of the swing rod located above the blocking plate and the rear side of the swing rod located above the lower pressure frame.

[0008] Furthermore, it also includes a positioning mechanism, which includes a turntable, a sliding block, an elastic element II, and a pressure plate. The turntable is rotatably connected to the rotating shaft, and the turntable is provided with an annular boss. The sliding block is slidably connected to the rotating shaft, and a pressure plate is connected to one side of the sliding block. The pressure plate is located inside the boss, and an elastic element II is connected between the pressure plate and the turntable.

[0009] Furthermore, it also includes a feeding mechanism, which includes a feeding frame, a blocking frame, an elastic element, a blocking block, and a push block. The feeding frame is clamped onto the clamping frame, and the feeding frame has a feeding port that is aligned with the feeding plate. The blocking frame is slidably connected to the feeding frame, and an elastic element is connected between the blocking frame and the feeding frame. Blocks are connected to both sides of the blocking frame, and the blocking blocks have inclined guide grooves. Push blocks are connected to both sides of the clamping frame, and the push blocks can contact and compress the inclined guide grooves.

[0010] Furthermore, it also includes an unloading mechanism, which includes a slide rod, an extension plate, a pusher frame, a connecting plate, and a cam shaft. The slide rod is slidably connected to the clamping frame, and the top of the slide rod is connected to the extension plate. The extension plate is located to the right of the pusher plate. The pusher frame is slidably connected to the clamping frame, and the upper part of the pusher frame is located in the receiving groove. The middle part of the pusher frame is connected to the connecting plate, and an inclined groove is formed on the connecting plate. The cam shaft is connected to the slide rod, and the cam shaft is located in the inclined groove.

[0011] Furthermore, it also includes a jetting mechanism, which includes an air pump, a jetting head, and an air injection pipe. The air pump is installed in the middle of the top of the clamping frame, and the jetting head is installed on the clamping frame of the air pump. The jetting head is located above the feeding plate, and an air injection pipe is connected between the jetting head and the air outlet of the air pump.

[0012] Furthermore, it also includes a collection mechanism, which includes a workpiece collection frame, partitions and a debris collection frame. The workpiece collection frame is connected to the lower part of the machine tool. Multiple partitions are evenly spaced at the bottom of the workpiece collection frame, and there are gaps between the partitions. The debris collection frame is connected to the bottom of the machine tool.

[0013] 1. After the raw material is cut, this invention only needs to control the electric push rod to retract and drive the blocking plate to move upward, which can release the raw material and replenish the subsequent raw material into the receiving tank for subsequent cutting work. There is no need for frequent manual addition of raw materials, making the operation more convenient.

[0014] 2. In this invention, after the raw material is cut into a workpiece, the cylinder telescopic rod drives the pusher plate to reset, which in turn drives the slide rod to move, thereby driving the cam shaft to squeeze the inclined groove, causing the connecting plate and the pusher frame to move upward. When the pusher frame moves upward, it can push out the formed workpiece, so as to realize the automatic unloading of the workpiece without the need for manual unloading, making the operation more convenient.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] A cutting device for milling cutter production, such as Figures 1-4 As shown, the machine tool includes a machine tool 1, a dual-axis moving system 2, a clamping frame 3, a cylinder 4, a pusher plate 5, a drive motor 6, a rotary shaft 7, a cutting head 8, a feeding mechanism, and a clamping mechanism. The dual-axis moving system 2 is installed on the rear side of the machine tool 1, and the cutting head 8 is installed on the dual-axis moving system 2. The clamping frame 3 is installed in the lower part of the machine tool 1. The cylinder 4 is installed on the right side of the clamping frame 3, and the pusher plate 5 is rotatably connected to the telescopic rod of the cylinder 4. The drive motor 6 is installed on the left side of the machine tool 1, and the rotary shaft 7 is rotatably connected to the output shaft of the drive motor 6. The rotary shaft 7 passes through the left side of the clamping frame 3 and is rotatably connected to the clamping frame 3. The clamping frame 3 is provided with a feeding mechanism and a clamping mechanism. The feeding mechanism is used to add milling cutter raw material 100.

[0031] like Figure 3 and Figure 4 As shown, the feeding mechanism includes an electric push rod 91, a blocking plate 92, and a feeding plate 93. The electric push rod 91 is mounted on the clamping frame 3, and the feeding plate 93 is connected to the lower part of the clamping frame 3. The feeding plate 93 is inclined with the front lower and the back higher. A receiving groove is provided on the front side of the feeding plate 93. The blocking plate 92 is connected to the telescopic rod of the electric push rod 91, and the blocking plate 92 can block the feeding plate 93.

[0032] like Figure 3 and Figure 4As shown, the clamping mechanism includes a lower pressure frame 94, an elastic element 95, and a swing rod 96. The lower pressure frame 94 is slidably connected to the upper part of the clamping frame 3. The lower pressure frame 94 can press down the milling cutter material 100 to prevent the milling cutter material 100 from shifting. An elastic element 95 is connected between the lower pressure frame 94 and the clamping frame 3. The elastic element 95 is a connecting spring. The swing rod 96 is rotatably connected to the middle of the front side of the clamping frame 3. The front side of the swing rod 96 is located above the blocking plate 92, and the rear side of the swing rod 96 is located above the lower pressure frame 94, so that the blocking plate 92 can move up to contact the swing rod 96 and squeeze the swing rod 96 to swing. The swing of the swing rod 96 can squeeze the lower pressure frame 94 to move down.

[0033] When milling cutters are needed for production processing, this cutting device can be used for processing. During operation, the raw material 100 is first piled up behind the feed plate 93, and the baffle plate 92 blocks the raw material 100 behind it. When adding raw material 100, the electric push rod 91 is controlled to retract, causing the baffle plate 92 to move upward. At this time, one raw material 100 will be exposed. The raw material 100 will roll along the feed plate 93 to the receiving groove. When the baffle plate 92 moves upward, it can also contact the swing rod 96 and squeeze the swing rod 96 to swing. The swing rod 96 swings and squeezes the lower pressure frame 94 to move downward. The elastic element 95 is stretched. The lower pressure frame 94 moves downward and can press down the other raw materials 100, thereby fixing the remaining raw materials 100 and preventing them from sliding out together. After adding one raw material 100, the electric push rod 91 is controlled to extend, causing the baffle plate 92 to block the remaining raw materials 100. Then, the extension rod of cylinder 4 can be controlled to extend and drive the pusher plate 5 to move to the left. The pusher plate 5 moves to the left and can contact and squeeze the material 100 to move to the left, so that the left side of the material 100 abuts against the rotating shaft 7. Then, the drive motor 6 can be controlled to drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it will drive the material 100 to rotate. At this time, the dual-axis moving system 2 is controlled to drive the cutting head 8 to move and cut the material 100 into a milling cutter. After the cutting is completed, the extension rod of cylinder 4 is controlled to retract and drive the pusher plate 5 to reset. Then the formed workpiece is taken out. Then, the extension rod of electric push rod 91 is controlled to retract to add the next formed workpiece. This process is repeated, so that the device can be used to perform milling operations. After the cutting is completed, the material 100 can be automatically added, making the operation more convenient.

[0034] like Figure 5 and Figure 6As shown, it also includes a positioning mechanism, which includes a turntable 101, a sliding block 102, an elastic element 103, and a pressure plate 104. The turntable 101 is rotatably connected to the right side of the rotating shaft 7. An annular boss is provided on the right side of the turntable 101. The sliding block 102 is slidably connected to the right side of the rotating shaft 7. The pressure plate 104 is connected to the right side of the sliding block 102. The pressure plate 104 is located inside the boss and is located on the left side of the receiving groove. An elastic element 103, which is a return spring, is connected between the pressure plate 104 and the turntable 101.

[0035] When the raw material 100 moves to the left, it extends into the boss of the turntable 101, and then squeezes the pressure plate 104 to move to the left. The elastic element 103 is compressed and applies pressure to the pressure plate 104, thereby holding the raw material 100 in place and helping to fix the raw material 100. At the same time, the boss restricts the raw material 100, preventing the position of the raw material 100 from shifting during the cutting process and ensuring the stability of the cutting operation.

[0036] like Figures 7-9 As shown, it also includes a feeding mechanism, which includes a feeding frame 111, a blocking frame 112, an elastic element 113, a blocking block 114, and a push block 115. The feeding frame 111 is engaged with the rear side of the clamping frame 3. A feeding port is opened at the lower front side of the feeding frame 111, which is aligned with the feeding plate 93. The blocking frame 112 is slidably connected to the lower front side of the feeding frame 111. The blocking frame 112 can slide up and down along the feeding frame 111. The blocking frame 112 and the feeding frame 115 are connected together. An elastic element 113 is connected between the frames 111. The elastic element 113 is a compression spring. Blocking blocks 114 are connected to both the left and right sides of the blocking frame 112. The blocking blocks 114 can block the feed port when they move upward. The blocking blocks 114 are provided with inclined guide grooves. Push blocks 115 are connected to both the left and right sides of the rear side of the clamping frame 3. The push blocks 115 can contact and squeeze the inclined guide grooves, thereby driving the blocking blocks 114 to move downward, so that the blocking blocks 114 no longer block the feed port.

[0037] During the cutting process, the raw material 100 can be added into the feeding frame 111. The two blocking blocks 114 can block the raw material 100. After the addition is completed, the feeding frame 111 can be clamped onto the clamping frame 3 so that the feeding port is aligned with the feeding plate 93. At this time, the push block 115 will also squeeze the inclined guide groove, thereby causing the blocking frame 112 and the blocking block 114 to move downward. The elastic element 3 113 is compressed. After the blocking block 114 moves downward, it no longer blocks the feeding port. When the raw material 100 on the feeding plate 93 decreases, the raw material 100 in the feeding frame 111 will enter the feeding plate 93 through the feeding port, thereby achieving the effect of replenishing the raw material 100. There is no need for frequent manual addition of the raw material 100, making the operation more convenient.

[0038] like Figure 10 and Figure 11 As shown, it also includes an unloading mechanism, which includes a slide rod 121, an extension plate 122, a pusher frame 123, a connecting plate 124, and a cam shaft 125. The slide rod 121 is slidably connected to the lower right side of the clamping frame 3, and the extension plate 122 is connected to the top right side of the slide rod 121. The extension plate 122 is located to the right of the pusher plate 5. The pusher frame 123 is slidably connected to the lower front side of the clamping frame 3. The upper part of the pusher frame 123 is located in the receiving groove. The upward movement of the pusher frame 123 can push out the formed workpiece in the receiving groove. The middle part of the pusher frame 123 is connected to the connecting plate 124, and an inclined groove is opened on the connecting plate 124. The left side of the slide rod 121 is connected to the cam shaft 125, and the cam shaft 125 is located in the inclined groove so that the movement of the cam shaft 125 can squeeze the inclined groove, thereby driving the connecting plate 124 to move.

[0039] After the raw material 100 is cut, when the cylinder 4 retracts its telescopic rod, it drives the pusher plate 5 to move to the right. The pusher plate 5 will contact the extension plate 122 and press the extension plate 122 to move to the right. When the extension plate 122 moves to the right, it will drive the slide rod 121 to move to the right. The slide rod 121 moving to the right can drive the cam shaft 125 to move to the right. The cam shaft 125 moving to the right can press the inclined groove, thereby driving the connecting plate 124 to move upward. When the connecting plate 124 moves upward, it will drive the pusher frame 123 to move upward. When the pusher frame 123 moves upward, it can push out the formed workpiece. In this way, the effect of automatically unloading the workpiece can be achieved without manual removal of the formed workpiece, making the operation more convenient.

[0040] like Figure 12As shown, it also includes a jetting mechanism, which includes an air pump 131, a jetting head 132, and an air injection pipe 133. The air pump 131 is installed in the middle of the top of the clamping frame 3. The jetting head 132 is installed on the upper front side of the clamping frame 3 of the air pump 131. The jetting head 132 is located above the feeding plate 93. The air injection pipe 133 connects the jetting head 132 and the air outlet of the air pump 131 so that the air output from the air pump 131 can enter the jetting head 132 through the air injection pipe 133, thereby causing the jetting head 132 to spray out gas.

[0041] During the cutting process, debris will be generated. At this time, the air pump 131 can be controlled to inject air into the air injection pipe 133. The gas in the air injection pipe 133 will enter the jet nozzle 132 and be ejected through the jet nozzle 132, thereby blowing away the generated debris and preventing the debris from accumulating on the feed plate 93.

[0042] like Figure 13 As shown, it also includes a collection mechanism, which includes a workpiece collection frame 141, partitions 142, and a chip collection frame 143. The workpiece collection frame 141 is connected to the lower part of the machine tool 1. The workpiece collection frame 141 is located below the front side of the feed plate 93. After the processed workpiece is pushed out, it will fall into the workpiece collection frame 141. Multiple partitions 142 are evenly spaced at the bottom of the workpiece collection frame 141. There are gaps between the partitions 142. The chip collection frame 143 is connected to the bottom of the machine tool 1. The chip collection frame 143 can collect the chips during the cutting process. After the chips fall into the workpiece collection frame 141, they will fall through the gaps between the partitions 142 and fall into the chip collection frame 143.

[0043] The technical principles of the embodiments of the present invention have been described above with reference to specific examples. These descriptions are merely for explaining the principles of the embodiments of the present invention and should not be construed as limiting the scope of protection of the embodiments of the present invention in any way. Based on the explanation herein, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the embodiments of the present invention.
