DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments 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.

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

[0031] like Figure 3 and Figure 4 As shown, the unloading mechanism includes an electric push rod 91, a blocking plate 92 and a feeding plate 93. The electric push rod 91 is installed 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 rear higher. A receiving groove is arranged on the front side of the feeding plate 93, and 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 member 95 and a swing rod 96. The upper part of the clamping frame 3 is slidably connected to the lower pressure frame 94. The lower pressure frame 94 moves downward to press the milling cutter raw material 100 to prevent the milling cutter raw material 100 from moving. An elastic member 95 is connected between the lower pressure frame 94 and the clamping frame 3. The elastic member 95 is a connecting spring. The middle part of the front side of the clamping frame 3 is rotatably connected to the swing rod 96. 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 moves upward to contact the swing rod 96 and squeeze the swing rod 96 to swing, and the swing of the swing rod 96 can squeeze the lower pressure frame 94 to move downward.

[0033] When the milling cutter needs to be processed, the present cutting device can be used for processing. During operation, the raw material 100 is first piled on the rear side of the feeding plate 93, and the blocking plate 92 blocks the raw material 100 on the rear side. When the raw material 100 needs to be added, the telescopic rod of the electric push rod 91 is controlled to retract and drive the blocking plate 92 to move up. At this time, a raw material 100 will be exposed, and the raw material 100 will roll along the feeding plate 93 to the receiving groove. When the blocking plate 92 moves up, 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 pressing frame 94 to move down. The elastic member 95 is stretched, and the lower pressing frame 94 moves down to press other raw materials 100, thereby fixing the remaining raw materials 100 to prevent the remaining raw materials 100 from sliding out together. After adding a raw material 100, the telescopic rod of the electric push rod 91 is controlled to extend and drive the blocking plate 92 to block the remaining raw materials 100. Yes, then the telescopic rod of the cylinder 4 can be controlled to extend and drive the pushing plate 5 to move to the left. The pushing plate 5 can move to the left and contact with the raw material 100 and squeeze the raw material 100 to move to the left, so that the left side of the raw material 100 is against the rotating shaft 7. Then the driving motor 6 can be controlled to drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, it will drive the raw material 100 to rotate. At this time, the dual-axis moving system 2 is controlled to drive the cutting head 8 to move, and the raw material 100 is cut into a milling cutter. After cutting, the telescopic rod of the cylinder 4 is controlled to retract and drive the pushing plate 5 to reset, and then the formed workpiece is taken out. At this time, the telescopic rod of the electric push rod 91 is controlled to retract to add the next formed workpiece. This is repeated, and the milling cutter can be cut using the present device. After the cutting process is completed, the raw material 100 can be added automatically, which is more convenient to operate.

[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 member 103 and a pressure plate 104. The turntable 101 is rotatably connected to the right side of the rotating shaft 7, and a circular boss is arranged on the right side of the turntable 101. The sliding block 102 is slidably connected to the right side of the rotating shaft 7, and a pressure plate 104 is connected to the right side of the sliding block 102. The pressure plate 104 is located in the boss, and the pressure plate 104 is located on the left side of the accommodating groove. An elastic member 103 is connected between the pressure plate 104 and the turntable 101, and the elastic member 103 is a reset spring.

[0035] When the raw material 100 moves to the left, it will extend into the boss of the turntable 101, and then squeeze the pressure plate 104 to move to the left, and the elastic member 103 will be compressed. The elastic member 103 applies pressure to the pressure plate 104, thereby resisting the raw material 100 and assisting in fixing the raw material 100. At the same time, the restriction of the boss can limit the position of the raw material 100 to avoid the position of the raw material 100 from shifting during the cutting process, thereby ensuring the stability of the cutting work.

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

[0037] When cutting, the raw material 100 can be added into the feeding frame 111 first, and the two blocking blocks 114 can block the raw material 100. After adding, the feeding frame 111 can be clamped on the clamping frame 3 so that the feeding port is aligned with the feeding plate 93. At this time, the pushing block 115 will also squeeze the inclined guide groove, so that the blocking frame 112 and the blocking block 114 move downward, and the elastic member 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 is reduced, 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 manual and frequent addition of the raw material 100, and the operation is more convenient.

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

[0039] After the cutting of the raw material 100 is completed, when the telescopic rod of the cylinder 4 retracts and drives the pushing plate 5 to move to the right, the pushing plate 5 will contact the extension plate 122 and squeeze the extension plate 122 to move to the right, and the extension plate 122 will drive the sliding rod 121 to move to the right, and the sliding rod 121 moving to the right can drive the convex shaft 125 to move to the right, and the convex shaft 125 moving to the right can squeeze the inclined groove, thereby driving the connecting plate 124 to move upward, and the connecting plate 124 will drive the pushing frame 123 to move upward when moving upward, and the pushing frame 123 can push out the formed workpiece when moving upward, so that the effect of automatically unloading the workpiece can be achieved, and there is no need to manually take out the formed workpiece, and the operation is more convenient.

[0040] like Fig.12As shown, it also includes an injection mechanism, which includes an air pump 131, an injection 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, and the injection head 132 is installed on the upper front side of the clamping frame 3 of the air pump 131. The injection head 132 is located above the feeding plate 93, and the injection pipe 133 is connected between the injection head 132 and the air outlet end of the air pump 131, so that the air outlet of the air pump 131 can enter the injection head 132 through the injection pipe 133, so that the injection head 132 can spray the gas.

[0041] During the cutting process, debris will be generated. At this time, the air pump 131 can be controlled to inject gas into the gas injection pipe 133. The gas in the gas injection pipe 133 will enter the nozzle 132 and be sprayed out through the nozzle 132, so as to blow away the generated debris and prevent the debris from accumulating on the feed plate 93.

[0042] like Fig.13 As shown, a collecting mechanism is also included, and the collecting mechanism includes a workpiece collecting frame 141, a partition 142 and a debris collecting frame 143. The lower part of the machine tool 1 is connected to the workpiece collecting frame 141, and the workpiece collecting frame 141 is located at the lower front side of the feed plate 93. The processed workpiece will fall into the workpiece collecting frame 141 after being pushed out. A plurality of partitions 142 are evenly connected to the bottom of the workpiece collecting frame 141, and there are gaps between the partitions 142. The bottom of the machine tool 1 is connected to a debris collecting frame 143, and the debris collecting frame 143 can collect debris generated during the cutting process. After the debris generated during the cutting process falls into the workpiece collecting frame 141, it will fall through the gaps between the partitions 142, and the fallen debris will fall into the debris collecting frame 143.

[0043] The technical principles of the embodiments of the present invention are described above in conjunction with specific embodiments. These descriptions are only for explaining the principles of the embodiments of the present invention and cannot be interpreted in any way as limiting the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific implementation methods of the embodiments of the present invention without creative work, and these methods will fall within the protection scope of the embodiments of the present invention.
