Description

Technical Field

[0001] This utility model belongs to the field of milling cutter processing technology, specifically a polishing device for milling cutter production. Background Technology

[0002] A milling cutter is a cutting tool used in metalworking for milling processes. It achieves cutting by the relative movement of the rotating cutting edge and the workpiece.

[0003] Milling cutter polishing is a key step in the milling cutter manufacturing process to improve the performance and service life of the milling cutters. Polishing significantly reduces the surface roughness of the milling cutter, thereby reducing friction and heat generation during use. At the same time, the smooth surface reduces chip adhesion to the milling cutter, reducing wear and extending the milling cutter's service life. Existing milling cutter polishing devices can polish multiple milling cutters simultaneously. However, when installing the milling cutters on the polishing device, each milling cutter needs to be installed and fixed one by one, and then removed one by one after polishing, which is inconvenient and affects processing efficiency.

[0004] Therefore, this utility model provides a polishing device for milling cutter production. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A polishing device for milling cutter production, comprising a polishing tank; a bracket fixedly connected to the top of the polishing tank; a first electric cylinder fixedly connected to the middle of the bracket; a mounting frame fixedly connected to the output end of the first electric cylinder; a bearing plate rotatably connected to the bottom of the mounting frame; a motor fixedly connected to the middle of the mounting frame; a first gear fixedly connected to the output end of the motor; a second gear fixedly connected to the top of the bearing plate; the first gear and the second gear meshing; a connecting component provided at the bottom of the first gear; multiple perforated positioning rods fixedly connected to the top of the connecting component; the multiple perforated positioning rods detachably installed in the middle of the bearing plate; multiple insertion rods rotatably connected to the top of the bearing plate; and multiple clamping components provided at the bottom of the connecting component. Through the above structure, multiple sets of milling cutters can be polished in batches, and a set of milling cutters can be simultaneously removed from and installed from the polishing device, reducing the inconvenience of removing and installing multiple milling cutters one by one and improving work efficiency.

[0007] Preferably, the connecting assembly includes an inner bearing ring and an outer bearing ring; the inner and outer bearing rings are components of a bearing ring; multiple perforated positioning rods are fixed to the top of the inner bearing ring; a limiting protrusion is fixed to the outer side wall of the outer bearing ring; a rubber ring is fixed to the bottom of the outer bearing ring; multiple rotating seats are rotatably connected to the bottom of the inner bearing ring; the middle of the rotating seats is fitted into the inside of the rubber ring; the clamping assembly is fixed to the bottom of the rotating seats; through the above structure, multiple milling cutters can rotate on their own axis while revolving around the center, so that each surface of the milling cutter can fully and evenly interact with the polishing material, thereby improving the polishing effect of the milling cutter.

[0008] Preferably, the clamping assembly includes a loading tube; the loading tube is fixedly connected to the bottom of the rotating seat; a tensioning groove is provided in the middle of the loading tube; the outer diameter of the loading tube gradually increases from top to bottom; an adjusting ring is slidably connected to the middle of the loading tube; a collar is rotatably connected to the middle of the adjusting ring; and a connecting ring is fixedly connected between multiple collars. Through the above structure, the clamping and unclamping of multiple milling cutters can be completed simultaneously, improving the ease of use of the device and helping to improve work efficiency.

[0009] Preferably, a second electric cylinder is fixedly connected to the side wall of the bracket; an arc-shaped plate is fixedly connected to the output end of the second electric cylinder; and multiple brushes are fixedly connected to the side wall of the arc-shaped plate. With the above structure, after the milling cutter has been polished, the impurities remaining on the surface of the milling cutter can be easily cleaned, reducing the inconvenience caused by the adhesion of impurities to subsequent processing.

[0010] Preferably, a rubber ring is fixed to the middle of the adjusting ring; the rubber ring is located between the adjusting ring and the loading tube; through the above structure, the wear between the adjusting ring and the loading tube is reduced, and during the polishing of the milling cutter, the movement of the adjusting ring is reduced, which may cause the clamping force of the loading tube on the milling cutter to decrease.

[0011] Preferably, a limiting groove is formed on the top of the bearing plate; the shape of the limiting groove is the same as the bottom shape of the insert rod; with the above structure, the occurrence of the insert rod vibrating and shifting, causing the perforated positioning rod to separate from the bearing plate and the milling cutter to fall off, can be reduced during the polishing process.

[0012] Preferably, a plurality of ball bearings are installed in the middle of the mounting bracket; the plurality of ball bearings are disposed below the support plate; the above structure can reduce wear between the mounting bracket and the support plate and improve the service life of the component.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] like Figures 1 to 5As shown, a polishing device for milling cutter production according to an embodiment of the present invention includes a polishing tank 1; a bracket 12 is fixedly connected to the top of the polishing tank 1; a first electric cylinder 13 is fixedly connected to the middle of the bracket 12; a mounting frame 14 is fixedly connected to the output end of the first electric cylinder 13; a bearing plate 15 is rotatably connected to the bottom of the mounting frame 14; a motor 16 is fixedly connected to the middle of the mounting frame 14; a first gear 17 is fixedly connected to the output end of the motor 16; a second gear 18 is fixedly connected to the top of the bearing plate 15; the first gear 17 and the second gear 18 are meshed; the bottom of the first gear 17 is provided with... A connecting assembly is included; multiple perforated positioning rods 19 are fixedly attached to the top of the connecting assembly; these perforated positioning rods 19 are detachably mounted on the center of the support plate 15; multiple insertion rods 110 are rotatably connected to the top of the support plate 15; multiple clamping components are provided at the bottom of the connecting assembly; during operation, multiple milling cutters are clamped using the clamping components, then the connecting assembly is placed below the support plate 15, and the connecting assembly is moved so that the multiple perforated positioning rods 19 are inserted upwards into the through holes in the center of the support plate 15. After the holes in the center of the perforated positioning rods 19 protrude from above the support plate 15, the insertion rods 110 are rotated... The rod 110 passes through the hole in the middle of the perforated positioning rod 19, making it difficult for the perforated positioning rod 19 to separate from the carrier plate 15. This allows the connecting assembly, multiple clamping assemblies, and the milling cutters clamped by the clamping assemblies to be mounted below the carrier plate 15. By activating the first electric cylinder 13, the mounting bracket 14 and the carrier plate 15 are lowered, causing multiple milling cutters to fall into the polishing material inside the polishing pool 1. Then, the motor 16 is activated to drive the first gear 17 to rotate, which in turn drives the second gear 18 and the carrier plate 15 to rotate, thereby causing the multiple milling cutters to move in the polishing material. The internal rotation is used for polishing. After a batch of milling cutters has been polished, the insert rod 110 can be rotated to separate the insert rod 110 from the positioning rod 19 with holes, so that the connecting assembly carrying the milling cutter can be separated from the carrier plate 15. Then, another connecting assembly carrying a new milling cutter is installed under the carrier plate 15 for a new round of polishing. With the above structure, multiple sets of milling cutters can be polished in batches, and a set of milling cutters can be taken out and installed from the polishing device at the same time, reducing the inconvenience of taking out and installing multiple milling cutters one by one and improving work efficiency.

[0026] like Figures 1 to 5As shown, the connecting assembly includes an inner bearing ring 2 and an outer bearing ring 21; the inner bearing ring 2 and the outer bearing ring 21 are components of the bearing ring; multiple perforated positioning rods 19 are fixed to the top of the inner bearing ring 2; a limiting protrusion 22 is fixed to the outer side wall of the outer bearing ring 21; a rubber ring 23 is fixed to the bottom of the outer bearing ring 21; multiple rotating seats 24 are rotatably connected to the bottom of the inner bearing ring 2; the middle part of the rotating seat 24 and the inside of the rubber ring 23 are fitted together; a clamping assembly is fixed to the bottom of the rotating seat 24; during operation, after the multiple perforated positioning rods 19 are connected to the bearing plate 15, the inner bearing ring 2 will rotate synchronously with the bearing plate 15, thereby driving the multiple rotating seats 24 to rotate. The lower milling cutter revolves around the rotation axis of the bearing plate 15. When the bearing plate 15 starts to rotate, the outer ring 21 of the bearing rotates simultaneously with the inner ring 2 of the bearing. Subsequently, the limiting protrusion 22 is blocked by the bottom side wall of the mounting bracket 14, thereby stopping the outer ring 21 of the bearing from rotating. At this time, the outer ring 21 of the bearing and the rubber ring 23 do not rotate, while the inner ring 2 of the bearing and multiple rotating seats 24 rotate. When the multiple rotating seats 24 rotate, they will be rubbed by the rubber ring 23 and thus rotate on their own axis. Through the above structure, multiple milling cutters can rotate on their own axis while revolving, so that each surface of the milling cutter can fully and evenly interact with the polishing material, thereby improving the polishing effect of the milling cutter.

[0027] like Figures 1 to 5 As shown, the clamping assembly includes a loading tube 25; the loading tube 25 is fixedly connected to the bottom of the rotating seat 24; a tensioning groove 3 is provided in the middle of the loading tube 25; the outer diameter of the loading tube 25 gradually increases from top to bottom; an adjusting ring 32 is slidably connected to the middle of the loading tube 25; a collar 31 is rotatably connected to the middle of the adjusting ring 32; a connecting ring 33 is fixedly connected between multiple collars 31; during operation, when polishing a batch of milling cutters, another connecting assembly is taken out, and the next batch of milling cutters to be polished is inserted into the multiple loading tubes 25 respectively, and then the connecting ring 33 is pulled together. The movement of multiple collars 31 causes multiple adjusting rings 32 to move along the outer surface of the loading tube 25, moving the adjusting rings 32 from the thinner part of the loading tube 25 to the thicker part, causing the loading tube 25 to deform and squeeze and clamp the milling cutter inside. After polishing the milling cutter, pushing the connecting ring 33 will move the multiple adjusting rings 32 to the thinner part of the loading tube 25, so that the multiple loading tubes 25 can simultaneously release the restriction on the milling cutter. Through the above structure, the clamping and unclamping of multiple milling cutters can be completed simultaneously, improving the ease of use of the device and helping to improve work efficiency.

[0028] like Figures 1 to 6As shown, a second electric cylinder 4 is fixedly connected to the side wall of the bracket 12; an arc-shaped plate 41 is fixedly connected to the output end of the second electric cylinder 4; and multiple brushes 42 are fixedly connected to the side wall of the arc-shaped plate 41. During operation, after the milling cutter has finished polishing, fine polishing material and other impurities may remain on the surface of the milling cutter. At this time, the second electric cylinder 4 can be started to move the arc-shaped plate 41 to the vicinity of the support plate 15, and the multiple brushes 42 can be moved to the space between some of the milling cutters. Then, the motor 16 can be started to drive the multiple milling cutters to rotate, so that the multiple brushes 42 can clean the impurities remaining on the surface of the milling cutter. Through the above structure, the impurities remaining on the surface of the milling cutter can be easily cleaned after the milling cutter has finished polishing, reducing the inconvenience caused by the adhesion of impurities to subsequent processing.

[0029] like Figure 5 As shown, a rubber ring 5 is fixedly connected to the middle of the adjusting ring 32; the rubber ring 5 is located between the adjusting ring 32 and the loading tube 25; during operation, when the adjusting ring 32 moves along the outer side wall of the loading tube 25, the rubber ring 5 will replace the inner side wall of the adjusting ring 32 to generate friction with the middle of the loading tube 25, reducing the wear between the adjusting ring 32 and the loading tube 25. At the same time, as the rubber ring 5 deforms under force, the friction between the rubber ring 5 and the loading tube 25 will increase, thereby reducing the situation where the adjustment ring 32 moves and the clamping force of the loading tube 25 on the milling cutter decreases during the polishing process.

[0030] like Figure 3 As shown, a limiting groove 6 is provided on the top of the bearing plate 15; the shape of the limiting groove 6 is the same as the bottom shape of the insertion rod 110; during operation, after the insertion rod 110 is inserted into the middle of the perforated positioning rod 19, the insertion rod 110 will sink into the limiting groove 6, making it difficult for the insertion rod 110 to move easily. Through the above structure, the vibration displacement of the insertion rod 110 during the polishing process can be reduced, which may cause the perforated positioning rod 19 to separate from the bearing plate 15 and cause the milling cutter to fall off.

[0031] like Figure 3 As shown, a plurality of ball bearings 7 are installed in the middle of the mounting bracket 14; the plurality of ball bearings 7 are located below the bearing plate 15; through the above structure, the wear between the mounting bracket 14 and the bearing plate 15 can be reduced, and the service life of the components can be improved.

[0032] During operation, multiple milling cutters are clamped using a clamping assembly. Then, a connecting assembly is placed below the carrier plate 15, and the connecting assembly is moved to insert multiple perforated positioning rods 19 upwards into the through holes in the center of the carrier plate 15. Once the holes in the center of the perforated positioning rods 19 protrude from above the carrier plate 15, the insert rod 110 is rotated to pass through the holes in the center of the perforated positioning rods 19, making it difficult for the perforated positioning rods 19 to separate from the carrier plate 15. This allows the connecting assembly, multiple clamping assemblies, and the milling cutters clamped by the clamping assemblies to be installed below the carrier plate 15. The first electric cylinder 13 is activated, causing the mounting frame 14 and the carrier plate 15 to descend, allowing the multiple milling cutters to fall into the polishing material inside the polishing pool 1. Then, the motor 16 is activated, driving the first gear 17 to rotate. Wheel 17 drives the second gear 18 and the bearing disk 15 to rotate, thereby driving multiple milling cutters to rotate within the polishing material for polishing. After a batch of milling cutters has finished polishing, the insert rod 110 can be rotated to separate it from the perforated positioning rod 19, thus allowing the connecting assembly carrying the milling cutters to separate from the bearing disk 15. Then, another connecting assembly carrying new milling cutters is installed under the bearing disk 15 for a new round of polishing. After the multiple perforated positioning rods 19 are connected to the bearing disk 15, the inner bearing ring 2 rotates synchronously with the bearing disk 15, thereby driving the milling cutters mounted under the multiple rotating seats 24 to revolve around the rotation axis of the bearing disk 15. When the bearing disk 15 starts to rotate, the outer bearing ring 21 rotates simultaneously with the inner bearing ring 2. The movement is initiated, and then the limiting protrusion 22 is blocked by the bottom side wall of the mounting bracket 14, thereby stopping the outer ring 21 of the bearing from rotating. At this time, the outer ring 21 and the rubber ring 23 do not rotate, while the inner ring 2 and multiple rotating seats 24 rotate. When the multiple rotating seats 24 rotate, they will be rubbed by the rubber ring 23 and thus rotate on their own. When polishing a batch of milling cutters, another set of connecting components is taken out, and the next batch of milling cutters to be polished is inserted into multiple loading tubes 25 respectively. Then, the connecting ring 33 is pulled, which simultaneously drives multiple collars 31 to move, thereby driving multiple adjusting rings 32 to move along the outer surface of the loading tube 25, moving the adjusting rings 32 from the thinner part of the loading tube 25 to the thicker part, causing the loading tube 25 to deform and squeeze and clamp the milling cutters inside. When the process is completed... After polishing the milling cutter, pushing the connecting ring 33 moves multiple adjusting rings 32 to the narrower part of the loading tube 25, simultaneously releasing the milling cutter from the constraints of the multiple loading tubes 25. After polishing, the surface of the milling cutter may have fine polishing material and other impurities remaining. At this time, the second electric cylinder 4 can be activated to move the arc plate 41 to near the bottom of the bearing plate 15, and move multiple brushes 42 between some of the milling cutters. Then, the motor 16 is activated to drive multiple milling cutters to rotate, allowing the multiple brushes 42 to clean the impurities remaining on the surface of the milling cutters. When the adjusting ring 32 moves along the outer wall of the loading tube 25, the rubber ring 5 will replace the inner wall of the adjusting ring 32 to generate friction with the middle of the loading tube 25, reducing wear between the adjusting ring 32 and the loading tube 25.Simultaneously, as the rubber ring 5 deforms under stress, the friction between the rubber ring 5 and the loading tube 25 increases. After the insertion rod 110 is inserted into the middle of the perforated positioning rod 19, the insertion rod 110 will sink into the limiting groove 6, making it difficult for the insertion rod 110 to move easily.
