Description

Technical Field

[0001] The invention relates to the technical field of milling cutter production, in particular to a positioning and polishing device for milling cutter processing. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth used for milling. When working, each tooth cuts off the workpiece's excess in sequence and intermittently. Milling cutters are mainly used to process planes, steps, grooves, formed surfaces and cut off workpieces on milling machines.

[0003] In the production process of milling cutters, polishing is a crucial finishing process, especially for high-end high-speed steel milling cutters, which directly affects the surface quality, wear resistance, anti-adhesion, chip removal performance and ultimate cutting life of the tool. During the polishing process of the milling cutter, the chip grooves on the surface of the high-speed steel milling cutter are prone to residues after cleaning and other treatments during the production process. In the subsequent positioning polishing process, it is easy for debris to enter the gap between the polishing wheel and the milling cutter during the processing process, which will cause unexpected scratches during the polishing process. In the polishing process, in order to improve the accuracy, the polishing paste will be used for the last step of polishing. However, its residue blocks the chip groove, contaminates the tool surface, affects the coating quality and cutting performance, and manual cleaning has certain safety hazards and is easy to scratch the operator. For this reason, we propose a positioning polishing equipment for milling cutter processing to solve the above problems. Summary of the Invention

Multiple detachable docking frames 41 are provided at the bottom of the transmission ring 4. A conveying shaft 42 is movably provided at the bottom of the docking frame 41. A scraper 441 for cleaning the inside of the chip groove is provided on one side of the conveying shaft 42. When the milling cutter needs to be polished, the milling cutter can be clamped inside the limiting chuck 14, and the conveying frame 2 is driven to move as a whole by the push motor, which can drive the connecting ring 21 to move outside the milling cutter, and the number of docking frames 41 can be controlled according to different types of milling cutters. One end of the scraper 441 can be pressed against the inside of the chip groove, which can drive the transmission ring 4 and the combing ring 3 with a fixed top to move in a circle, and can quickly clean the surface of the milling cutter after clamping, reduce the residual debris, and facilitate subsequent polishing.

[0018] like Figure 3 As shown, the surface of the connecting ring 21 is connected to the air inlet pipe 26, and the outer wall of the connecting ring 21 is movably provided with an air delivery ring 23. The outer wall of the air delivery ring 23 is connected to multiple transmission hoses, and the transmission hoses are connected to the delivery shaft 42. The transmission hoses can pull the air delivery ring 23 to move in a circular motion; An annular air delivery groove is provided inside the connecting ring 21, and a plurality of straight holes for inserting positioning tubes 24 are provided inside the top of the annular air delivery groove. A sealing plug rod 25 for reset is inserted inside the positioning tube 24, and a push ball is provided on the top of the sealing plug rod 25. The downward movement of the sealing plug rod 25 can block the air flow transmission inside the annular air delivery groove. The movement of the sealing plug rod 25 can play a blocking role, thereby realizing intermittent air supply, which is convenient for subsequent cleaning of the milling cutter surface.

[0019] like Figure 4 and Figure 5 As shown, a plurality of positioning shafts 31 are connected to the outer wall of the top of the combing ring 3. A hollow shaft is connected to the side of the positioning shaft 31 close to the center of the combing ring 3, and a stretching belt is provided inside the hollow shaft. A swing plate 33 is hinged inside the positioning shaft 31. The swing plate 33 can rest on the top of the push ball at the top of the sealing plug 25. The swing plate 33 can swing slightly. As the swing plate 33 moves, it can not only squeeze the top of the push ball, but also slightly move itself to pull the stretching shaft on one side to move. A plurality of reset plates 32 are mounted on the inner wall of the combing ring 3 , one end of the reset plate 32 is connected to the stretching belt, and the reset plate 32 can be deformed as the stretching shaft moves.

[0020] like Figure 5As shown, in order to reduce the accidental situation of debris residue on the surface of the milling cutter, a plurality of elastic end blocks 34 are connected to the inner wall of the combing ring 3. The elastic end blocks 34 are staggered with the reset plate 32. The elastic end blocks 34 can follow the deformation and movement of the reset plate 32. The cleaning frame 341 is clamped on the elastic end block 34. The position of the cleaning frame 341 can be adjusted and a groove is provided on the side facing the center of the combing ring 3, and a replaceable sponge shaft is clamped inside the groove. During the circular motion of the transmission ring 4, the top combing ring 3 can be driven to move in a circular motion, and the corresponding cleaning frame 341 position can be adjusted to press it against the surface of the milling cutter to absorb excess moisture with the help of the sponge shaft. It should also be noted that during the transmission process, the swing plate 33 can interact with the push ball at the top of the sealing rod 25, thereby controlling the deformation of the tensile belt control reset plate 32 and controlling the movement of the cleaning frame 341 outside the elastic end block 34 during the transmission process, thereby further enhancing the cleaning effect on the milling cutter surface and reducing the adhesion of debris, oil, etc. on the subsequent polishing wheel surface, thereby extending the equipment maintenance cycle and reducing the inconsistent polishing effect caused by oil adhesion to the grinding wheel.

[0021] like Figure 6 and Figure 7 As shown, in order to clean the inside of the chip groove of the milling cutter and reduce the impact on subsequent polishing, a hollow welding shaft 43 is fixedly connected to one end of the conveying shaft 42. A reset cannula 44 is sleeved on the outside of the welding shaft 43. The reset cannula 44 and the welding shaft 43 form a piston cavity. The conveying shaft 42 is used to pass through the conveying tube and the welding shaft 43. A docking groove is provided at the top of the reset insert 44, and a fixed plug rod connected to a reset spring is provided at the rear end of the scraper 441. The scraper 441 is rotatably arranged at the top of the reset insert 44 with the help of the fixed plug rod, and the reset spring can control the reset of the scraper 441. The docking block 45 at one end of the scraper 441 is clamped inside the chip removal groove, and the docking block 45 itself is elastic and can swing along the arc of the chip removal groove during the transmission process, which can drive the cleaning plates 46 on both sides to move, so as to clean up the excess debris inside the chip removal groove and reduce the impact on subsequent grinding. It should also be noted that as air is intermittently supplied to the inside of the conveying shaft 42, the extrusion force received by the docking block 45 and the cleaning plate 46 changes back and forth, which can quickly shake off the debris generated during the cleaning process, which is more efficient and convenient than manual cleaning.

[0022] like Figure 7 As shown, a rectangular groove is provided at the top of the scraper 441, and a docking block 45 is provided inside the rectangular groove. The docking block 45 is made of elastic material and is used to rest against the inside of the milling cutter chip groove. The docking block 45 can be used to be clamped inside the chip groove to clean the chip groove on the surface of the milling cutter.

[0023] like Figure 7 Cleaning plates 46 are provided at both ends of the docking block 45. The cleaning plates 46 are hollow and elastic. A cloth pad is provided on the outer side of the cleaning plates 46 to absorb and remove debris and reduce residue.

[0024] like Figure 3 As shown, a rotating rod is installed on the top of the connecting end block 12, and a limiting chuck 14 is installed on the top of the rotating rod for limiting the milling cutter.

[0025] like Figure 2 As shown, a group of telescopic shafts 221 are installed on the top of the connecting ring 21, and a buffer baffle 22 is connected to the top of the telescopic shaft 221. A rubber pad is provided at the bottom of the buffer baffle 22, which can be against the top of the milling cutter.

[0026] Working principle: First, when the milling cutter needs to be polished, the milling cutter can be clamped inside the limiting chuck 14, and the conveying frame 2 is driven to move as a whole by the push motor, which can drive the connecting ring 21 to move outside the milling cutter, and the number of docking frames 41 can be controlled according to different types of milling cutters. One end of the cleaning scraper 441 can be pressed against the inside of the chip groove, which can drive the transmission ring 4 and the combing ring 3 at the top to move in a circle, and can quickly clean the surface of the milling cutter after clamping, reduce the situation of debris residue, and facilitate subsequent grinding. In the process of clamping and limiting, with the help of the limiting clamp The head 14 can make the milling cutter be set vertically. At this time, the position of the docking frame 41 is adjusted, and the docking block 45 at one end of the scraper 441 can be clamped inside the chip groove. The docking block 45 itself is elastic and can swing along the arc of the chip groove during the transmission process. It can drive the cleaning plates 46 on both sides to move, and clean the excess debris inside the chip groove, reducing the impact on subsequent grinding. When grinding with the aid of grinding paste, it can be cleaned with the help of the cleaning plate 46 before unloading to reduce residue. Compared with manual cleaning, it is more efficient and convenient. Then, during the circular motion of the transmission ring 4, the combing ring 3 at the top can be driven to move in a circular motion, and the position of the corresponding cleaning frame 341 can be adjusted to be pressed against the surface of the milling cutter, and the sponge shaft can be used to absorb excess moisture, etc., and as the transmission process progresses, the swing plate 33 can interact with the pushing ball at the top of the sealing plug 25, thereby controlling the deformation of the tensile belt control reset plate 32 and controlling the movement of the cleaning frame 341 outside the elastic end block 34 during the transmission process, thereby further enhancing the cleaning effect on the surface of the milling cutter and reducing the adhesion of debris, oil, etc. to the subsequent polishing wheel surface; Finally, during the transmission process, the air inlet pipe 26 can be connected to the external equipment, and the air flow can be transported along the transmission hose to the piston chamber formed by the welding shaft 43 and the reset tube 44, which is used to press the docking block 45 against the gap of the chip groove, and cooperate with the cleaning plate 46 to clean and maintain the inside of the chip groove. As the swing plate 33 at the top moves, the sealing rod 25 can be inserted into the annular air transmission groove to block the gap, and the extrusion force received by the docking block 45 and the cleaning plate 46 during the transmission process can be changed back and forth, and the debris generated during the cleaning process can be quickly shaken off, which is more efficient and convenient than manual cleaning.
