[0023] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] As Figures 1 to 4 shown, a camshaft processing mechanism with a stable limiting function according to an embodiment of the present invention includes an operating table 1. A cutting module 11 is installed on the top of the operating table 1. A fixed groove 12 is fixedly connected to the top of the operating table 1. The fixed groove 12 is provided in multiple sections on the top of the operating table 1. The fixed groove 12 is V-shaped. A first electric push rod 13 is fixedly connected to the top of the operating table 1 away from the cutting module 11. The driving end of the first electric push rod 13 is fixedly connected to a limit plate 14. The limit plate 14 slides on the top of the fixed groove 12. A fixing component is provided on the top of the operating table 1. The operating table 1 is provided with a blanking component through the fixing component. During work, according to the designed dimensions, the first electric push rod 13 is turned on. The first electric push rod 13 drives the limit plate 14 to slide to a specified position on the top of the fixed groove 12, so that the distance from the side wall of the limit plate 14 to the side wall of the saw blade inside the cutting module 11 is the same as the designed dimensions. The blank to be cut is placed in the middle of the fixed groove 12. The fixing component is used to fix the blank on the top of the fixed groove 12. The cutting module 11 is started. The cutting module 11 cuts the blank. After cutting is completed, the fixing component drives the blanking component to eject the cut blank from the fixed groove 12. Through the settings of the operating table 1, the cutting module 11, the fixed groove 12, the first electric push rod 13, the limit plate 14, the fixing component and the blanking component in this step, a cutting limit positioning structure is formed, realizing the function of cutting the blank to a fixed length, solving the function of measuring every time the same-sized blank is cut, simplifying the operation steps, reducing the workload, and increasing the convenience of cutting the blank to a fixed length.

[0025] As Figures 1 to 4As shown in the figure, the fixing component includes a first fixing frame 2, a second electric push rod 21, a pressing plate 22, a first fixing plate 23, a first V-shaped pressing block 24, a reverse tooth 25, a second fixing plate 26 and a second V-shaped pressing block 27. The first fixing frame 2 is fixedly connected to the top of the operating table 1. The second electric push rod 21 is fixedly connected to the top of the first fixing frame 2. The pressing plate 22 is fixedly connected to the transmission end of the second electric push rod 21. The first fixing plate 23 is slidably connected to the bottom of the pressing plate 22. The second fixing plate 26 is fixedly connected to the bottom of the pressing plate 22 close to the cutting module 11. The first V-shaped pressing block 24 is fixedly connected to the bottom end of the first fixing plate 23. The first V-shaped pressing block 24 is slidably connected to the side wall of the limiting plate 14 close to the first fixing frame 2. The second V-shaped pressing block 27 is fixedly connected to the bottom end of the second fixing plate 26. The reverse tooth 25 is fixedly connected to the inner side walls of the first V-shaped pressing block 24 and the second V-shaped pressing block 27. Multiple groups of reverse teeth 25 are arranged on the inner side walls of the first V-shaped pressing block 24 and the second V-shaped pressing block 27. During operation, when the limiting plate 14 moves, it drives the first fixing plate 23 and the first V-shaped pressing block 24 to move at the bottom of the pressing plate 22. After the blank to be cut is placed on the top of the fixing groove 12, the second electric push rod 21 is started. The second electric push rod 21 drives the pressing plate 22 to move downward. The pressing plate 22 drives the first fixing plate 23, the first V-shaped pressing block 24, the second fixing plate 26 and the second V-shaped pressing block 27 to move downward. The first V-shaped pressing block 24 and the second V-shaped pressing block 27 fix the blank on the top of the fixing groove 12. The reverse tooth 25 contacts the outer side wall of the blank. Through the arrangement of the first fixing frame 2, the second electric push rod 21, the pressing plate 22, the first fixing plate 23, the first V-shaped pressing block 24, the reverse tooth 25, the second fixing plate 26 and the second V-shaped pressing block 27 in this step, a blank fixing structure is formed, realizing the function of fixing the blank on the top of the fixing groove 12, solving the problems of shaking or deviation of the blank during cutting, improving the stability of the blank during cutting, increasing the adaptability of the device to blanks of different sizes, improving the adjustability of the device, and improving the accuracy of blank cutting.

[0026] As Figure 3As shown in the figure, the blanking component includes a second fixing frame 3, a guide rod 31, a spring 32, and an inclined block 33. The second fixing frame 3 is fixedly connected to the bottom of the pressing plate 22 close to the first fixing frame 2. The guide rod 31 is slidably connected to the middle of the second fixing frame 3. The inclined block 33 is fixedly connected to the bottom end of the guide rod 31. The inclined block 33 is in the middle of multiple fixed slots 12. The spring 32 is sleeved on the outer wall of the guide rod 31 away from the inclined block 33. During operation, the second electric push rod 21 is designed for two-stage downward pressing. When the first stage presses downward, the pressing plate 22 drives the second fixing frame 3, the guide rod 31, the spring 32, and the inclined block 33 to approach the operating table 1, so that the inclined block 33 contacts the top of the operating table 1. At this time, the blank is placed. After the placement is completed, the second electric push rod 21 drives the pressing plate 22 to perform the second downward pressing. The first V-shaped pressing block 24 and the second V-shaped pressing block 27 fix the blank. The second fixing frame 3 slides on the outer wall of the guide rod 31, and the spring 32 is stretched. After the cutting is completed, the second electric push rod 21 drives the second fixing frame 3, the guide rod 31, the spring 32, and the inclined block 33 to move upward. The inclined block 33 ejects the cut blank out of the fixed slot 12. Through the setting of the second fixing frame 3, the guide rod 31, the spring 32, and the inclined block 33 in this step, a blank ejection structure is formed, realizing the function of ejecting the blank from the fixed slot 12, solving the problem that the blank is not easy to take out from the fixed slot 12, improving the convenience of blanking, and increasing the automation degree of the device.

[0027] As Figure 4 shown, a chip removal groove 4 is opened in the middle of the operating table 1 close to the cutting module 11. A chip collection box 41 is detachably installed at the bottom of the operating table 1 close to the chip removal groove 4. During operation, the chips generated when the cutting module 11 cuts the blank fall into the chip collection box 41 through the chip removal groove 4 and are collected by the chip collection box 41. Through the setting of the chip removal groove 4 and the chip collection box 41 in this step, a chip collection structure is formed, realizing the function of collecting the chips generated by cutting, solving the problem of chip accumulation on the top of the operating table 1, and improving the convenience of chip collection.

[0028] As Figure 1 shown, a workpiece collection box 5 is fixedly connected to the side wall of the operating table 1 away from the first fixing frame 2. A sponge pad is installed at the bottom of the inner side wall of the workpiece collection box 5. During operation, after the blank is ejected, it rolls on the top of the operating table 1 and falls into the workpiece collection box 5. The sponge pad inside the workpiece collection box 5 buffers the blank. Through the setting of the workpiece collection box 5 and the sponge pad in this step, a blank collection structure is formed, improving the convenience of collecting the cut blank and reducing the situation of the blank falling and colliding with the workpiece collection box 5.

[0029] As Figure 1As shown in the figure, the bottom of the operating table 1 is fixedly connected with legs 6. Multiple groups of legs 6 are arranged at the bottom of the operating table 1 and are evenly distributed at the four corners of the bottom of the operating table 1. The bottom end of the leg 6 is fixedly connected with a foot plate 61. During operation, the leg 6 supports the device, and the foot plate 61 increases the stability of the device when placed. Through the setting of the leg 6 and the foot plate 61, this step forms a device support and fixation structure, improves the stability of the device during operation, and reduces the situation of the device tipping over.

[0030] As Figure 2 shown in the figure, the limiting plate 14 is made of stainless steel. During operation, since the limiting plate 14 is made of stainless steel, it reduces the scratching of the limiting plate 14 caused by the contact between the blank and the limiting plate 14, thereby preventing rusting, improves the service life of the limiting plate 14, and reduces the situation where the dimensional accuracy decreases due to the rusting of the limiting plate 14.

[0031] During operation, according to the design dimensions, the first electric push rod 13 is opened. The first electric push rod 13 drives the limit plate 14 to slide to a specified position on the top of the fixed slot 12, so that the distance from the side wall of the limit plate 14 to the side wall of the saw blade inside the cutting module 11 is the same as the design dimensions. Place the blank to be cut in the middle of the fixed slot 12, and use the fixing component to fix the blank on the top of the fixed slot 12. Start the cutting module 11, and the cutting module 11 cuts the blank. After cutting is completed, the fixing component drives the blanking component to eject the cut blank from the fixed slot 12. When the limit plate 14 moves, it drives the first fixing plate 23 and the first V-shaped pressing block 24 to move under the pressing plate 22. After the blank to be cut is placed on the top of the fixed slot 12, the second electric push rod 21 is started. The second electric push rod 21 drives the pressing plate 22 to move downward. The pressing plate 22 drives the first fixing plate 23, the first V-shaped pressing block 24, the second fixing plate 26 and the second V-shaped pressing block 27 to move downward. The first V-shaped pressing block 24 and the second V-shaped pressing block 27 fix the blank on the top of the fixed slot 12. The reverse teeth 25 are in contact with the outer side wall of the blank. The second electric push rod 21 is designed with two-stage downward pressure. When the first stage presses down, the pressing plate 22 drives the second fixing frame 3, the guide rod 31, the spring 32 and the inclined block 33 to approach the operating table 1, so that the inclined block 33 contacts the top of the operating table 1. At this time, place the blank. After placement is completed, the second electric push rod 21 drives the pressing plate 22 to perform the second downward pressure. The first V-shaped pressing block 24 and the second V-shaped pressing block 27 fix the blank. The second fixing frame 3 slides on the outer side wall of the guide rod 31, and the spring 32 is stretched. After cutting is completed, the second electric push rod 21 drives the second fixing frame 3, the guide rod 31, the spring 32 and the inclined block 33 to move upward. The inclined block 33 ejects the cut blank from the fixed slot 12. The chips generated when the cutting module 11 cuts the blank fall into the chip collection box 41 through the chip discharge groove 4 and are collected by the chip collection box 41. After the blank is ejected, it rolls on the top of the operating table 1 and falls into the workpiece collection box 5. The sponge pad inside the workpiece collection box 5 buffers the blank. The support legs 6 support the device, and the foot plates 61 increase the stability of the device when placed. The limit plate 14 is made of stainless steel, reducing the situation that the limit plate 14 is scratched due to contact with the blank, thus preventing rusting, improving the service life of the limit plate 14, and reducing the situation that the dimensional accuracy decreases due to rusting of the limit plate 14.
