Description

Technical Field

[0001] The invention belongs to the technical field of water pump shaft milling, in particular to a milling device and process for a water pump shaft. Background Art

[0002] A milling device for a water pump shaft is a mechanical device specially designed to process the water pump shaft. Its main function is to perform precise milling operations on the water pump shaft to remove excess material, form a specific shape or size, or process specific grooves, keyways and other structures.

[0003] In the prior art, for milling cutters that perform milling for a long time, chip fluid is often used to prevent the formation of built-up edge on the surface during the working process. The water pump shaft to be milled is manually placed between two sets of positioning mechanisms. At this time, the external driving source is started to enable the clamp to clamp the water pump shaft, and the milling cutter is further started to mill the water pump shaft. During the milling process, cutting fluid is used to cool the milling cutter, which can also reduce the formation of built-up edge.

[0004] There are still some problems in the actual application of the above scheme. Since the cutting fluid cannot completely avoid the formation of built-up edge during work, the existence of built-up edge makes it impossible for the milling cutter to maintain accurate cutting dimensions during the cutting process, affecting the dimensional accuracy of the processed workpiece; secondly, the built-up edge is scraped off by adding a scraper component. After use, the scraper has built-up edge or other impurities remaining on the surface, which will contaminate the milling cutter or the workpiece surface again when used next time, affecting the processing quality.

[0011] Preferably, a square groove is formed on the upper surface of the movable protrusion, a fixing column is fixedly connected to the side wall of the square groove, and a rotating piece is rotatably connected to the outer ring surface of the fixing column.

[0012] Preferably, an adjusting rod is fixedly connected to the top of the rotating piece, a buckle is fixedly connected to the side of the adjusting rod close to the fixed disk, a limiting column is fixedly connected to the bottom surface of the adjusting rod away from the buckle, a return spring is fixedly connected to the bottom of the limiting column, and a cylindrical groove is provided on the upper surface of the movable protrusion.

[0013] Preferably, a first contact is fixedly connected to a side wall of the inner cavity of the protective shell, and a second contact is fixedly connected to a side surface of the movable protrusion.

[0014] Preferably, a blocking and protecting mechanism for blocking splashing of built-up edge is provided on the top of the milling device body, and the blocking and protecting mechanism includes a fixed shell, the fixed shell is fixedly connected to the side of the milling device shell, an inner cavity is opened inside the fixed shell, a driving source is fixedly connected to the bottom of the inner cavity of the fixed shell, the driving source output shaft is fixedly connected to a rotating column, and a blocking roll plate is fixedly connected to the outer ring surface of the rotating column.

[0015] Preferably, an iron counterweight is fixedly connected to the bottom of the blocking roll plate, a guide groove is provided at one end of the iron counterweight, the iron counterweight is slidably connected inside the guide groove, a magnet is fixedly connected to the bottom of the guide groove, and the length of the magnet is the same as the length of the inner cavity opened in the milling device shell.

[0016] A milling process for a water pump shaft is specifically as follows:

[0017] Step 1, front process: first pre-process the materials that meet the processing requirements, then place the pre-processed materials into the positioning mechanism, determine the positioning reference during processing to ensure the accuracy of processing, and select appropriate tools and auxiliary tools;

[0018] Step 2, milling process: After the material has gone through the previous process, it will also go through three processes: rough machining, semi-finishing and finishing. During the machining process, the milling cutter and the material will produce built-up edge due to the high temperature, and the built-up edge will affect the subsequent machining accuracy. At this time, the two sets of electric telescopic rods in the cleaning mechanism will be started to push out the rotating scraper and the fixed scraper, so as to clean the built-up edge on the milling cutter;

[0019] Step 3, post-process: clean and rust-proof the pump shaft after the milling process, and perform quality inspection on it. Then assemble and debug it to ensure that all workpieces meet the performance index requirements.

[0020] The milling process of step 2 is specifically as follows: first, when the second moving block and the milling cutter move to the specified position, the electric telescopic rod fixedly connected to the side of the moving protrusion will be started, thereby pushing the rotating scraper and the fixed scraper to extend out of the cleaning sheet through the moving protrusion. Since the cleaning sheet is detachable and the material of the cleaning sheet is sponge, the chip fluid contained in the cleaning sheet will clean the fixed scraper and the rotating scraper. After the fixed scraper and the rotating scraper are extended, the milling cutter will rotate counterclockwise one hundred and eighty degrees under the drive of the existing drive so that the milling cutter head part can pass between the fixed scraper and the rotating scraper, thereby achieving the cleaning of the built-up edge on the milling cutter.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention can move the movable protrusion and all the components on the movable protrusion along the guide of the guide block through the reciprocating movement of the electric telescopic rod, so that after the second movable block and the milling cutter complete milling, it is ensured that the rotating scraper and the fixed scraper can extend the cleaning sheet. At this time, the milling cutter is rotated one hundred and eighty degrees counterclockwise through the existing drive so that the cutter head of the milling cutter can pass between the fixed scraper and the rotating scraper, thereby completing the cleaning of the built-up edge on the milling cutter. At the same time, when the second movable block and the milling cutter continue to work, the electric telescopic rod will drive the movable protrusion and all the components on the movable protrusion to move away from the milling device housing. Since the cleaning sheet is a sponge structure and contains chip liquid inside, it can clean the fixed scraper and the rotating scraper when they move away from the milling device housing, thereby extending the service life of the fixed scraper and the rotating scraper and avoiding damage to the surface of the milling cutter by residual substances on the surface during continuous work.

[0023] The present invention requires a staff member to manually lift the buckle and simultaneously rotate the fixed disc and determine the angle between the fixed scraper and the rotating scraper through the slope structure of the milling cutter, so as to ensure that the fixed scraper and the rotating scraper can adapt to the slope structure of the milling cutter. At the same time, after adjusting the angle between the fixed scraper and the rotating scraper, the staff member releases the buckle and the reset spring will reset, so that the adjusting rod and the buckle can rotate around the fixed column, so that the buckle can engage with the slot opened on the outer ring surface of the fixed disc, thereby reducing the phenomenon of angle deviation caused by the device during operation, and further can adapt to milling cutters of different sizes and reduce production costs.

[0024] The present invention starts the driving source by the abutment of the second contact and the first contact. When the driving source is started, the rotating column can be rotated counterclockwise, so that the blocking roll and the iron counterweight fixedly connected to the bottom of the blocking roll can move along the guide of the guide groove. At the same time, since the bottom of the inner cavity of the milling device shell is fixedly connected to the magnet, the iron counterweight will be sucked when it abuts against the magnet, thereby avoiding the splashing of built-up edge when the fixed scraper and the rotating scraper clean the surface of the milling cutter, thereby protecting the safety of surrounding personnel. Further, by blocking the splashing of built-up edge, the difficulty of waste collection in the later stage can be reduced, thereby improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] Embodiment 1

[0039] like Figures 1 to 8 As shown, one embodiment of the present invention is:

[0040] Specifically, the milling device body 1 includes a milling device shell 101, the milling device shell 101 is set on the ground, an inner cavity is opened inside the milling device shell 101, a first moving block 102 is slidably connected to the bottom of the inner cavity of the milling device shell 101, a fixed clamp 103 is fixedly connected to the side of the first moving block 102, a second moving block 104 is slidably connected to the bottom of the inner cavity of the milling device shell 101, a milling cutter 105 is rotatably connected to the side of the second moving block 104, a rotating cleaning mechanism 2 is arranged on the side of the milling device body 1, a cleaning sheet 220 is detachably installed on the side of the milling device shell 101, and a placement groove 201 is opened on the side of the milling device shell 101;

[0041] The rotary cleaning mechanism 2 includes a protective shell 202 , which is detachably connected to the side of the milling device housing 101 .

[0042] Specifically, since the cutting fluid cannot completely avoid the formation of built-up edge during work, the existence of built-up edge makes it impossible for the milling cutter to maintain accurate cutting dimensions during the cutting process, affecting the dimensional accuracy of the workpiece; secondly, by adding a scraper assembly to scrape off the built-up edge, the scraper will have built-up edge or other impurities on the surface after use, which will contaminate the milling cutter or workpiece surface again when used next time, affecting the processing quality.

[0043] Therefore, the present invention solves this problem by setting a certain structure. The reciprocating movement of the electric telescopic rod 219 can move the moving protrusion 205 and all the components on the moving protrusion 205 along the guide of the guide block 203, so that after the second moving block 104 and the milling cutter 105 complete the milling, it is ensured that the rotating scraper 207 and the fixed scraper 206 can extend the cleaning sheet 220. At this time, the milling cutter 105 is rotated 180 degrees counterclockwise by the existing drive so that the cutter head of the milling cutter 105 can pass between the fixed scraper 206 and the rotating scraper 207, thereby completing the cleaning of the built-up edge on the milling cutter 105. At the same time, when the second moving block 104 and the milling cutter 105 continue to work, the electric telescopic rod 219 can move the moving protrusion 205 and all the components on the moving protrusion 205 along the guide of the guide block 203. The retracted rod 219 will drive the moving protrusion 205 and all the parts on the moving protrusion 205 to move away from the milling device housing 101. Since the cleaning sheet 220 is a sponge structure and contains chip liquid, it can clean the fixed scraper 206 and the rotating scraper 207 when they move away from the milling device housing 101, thereby extending the service life of the fixed scraper 206 and the rotating scraper 207 and avoiding the damage of the surface of the milling cutter 105 by the residual substances on the surface during continuous work. Secondly, the staff manually lifts the buckle 214 and rotates the fixed disc 208 at the same time and determines the angle between the fixed scraper 206 and the rotating scraper 207 through the slope structure of the milling cutter 105. To ensure that the fixed scraper 206 and the rotating scraper 207 can be adapted to the slope structure of the milling cutter 105. At the same time, after adjusting the angle between the fixed scraper 206 and the rotating scraper 207, the staff releases the buckle 214. At this time, the reset spring 216 will be reset, so that the adjustment rod 213 and the buckle 214 rotate around the fixed column 211, so that the buckle 214 can be engaged with the slot 209 opened on the outer ring surface of the fixed disk 208, reducing the phenomenon of angle deviation caused by the device during operation, and further enabling the rotating cleaning mechanism 2 to adapt to milling cutters 105 of different sizes to reduce production costs. In addition, the second contact 217 and the first contact 204 are offset to start the drive source 3 02. When the driving source 302 is started, the rotating column 303 can rotate counterclockwise, so that the blocking roll 304 and the iron counterweight 306 fixedly connected to the bottom of the blocking roll 304 can move along the guide of the guide groove 305. At the same time, since the bottom of the inner cavity of the milling device housing 101 is fixedly connected to the magnet 307, the iron counterweight 306 will be sucked when it is against the magnet 307, so that the fixed scraper 206 and the rotating scraper 207 can be prevented from splashing the built-up edge when cleaning the surface of the milling cutter 105, thereby protecting the safety of the surrounding staff. Further, by blocking the splashing of the built-up edge, the difficulty of waste collection in the later stage can be reduced, thereby improving work efficiency.

[0044] The problem that the chip fluid of the milling cutter 105 cannot completely clean the built-up edge during the production process is solved. At the same time, the cleaning sheet 220 can be used to clean the fixed scraper 206 and the rotating scraper 207, thereby protecting the fixed scraper 206 and the rotating scraper 207. The reciprocating movement of the blocking roll 304 can further block the splashing built-up edge, thereby improving the collection efficiency of waste chips.

[0045] like Figure 6 As shown, in this embodiment, an inner cavity is opened inside the protective shell 202, and a guide block 203 is fixedly connected to the bottom of the inner cavity of the protective shell 202.

[0046] Specifically, since the protective shell 202 is detachably connected to the side wall of the milling device housing 101, and the guide block 203 fixed at the bottom of the inner cavity of the protective shell 202 is on the same horizontal line as the guide block 203 installed on the side wall of the placement groove 201, it is mainly used to guide the moving protrusion 205.

[0047] like Figure 6 As shown, in this embodiment, a movable protrusion 205 is slidably connected to the outer surface of the guide block 203, a fixed scraper 206 is fixedly connected to the side of the movable protrusion 205, the fixed scraper 206 is slidably connected to the inside of the milling cutter 105, a rotating scraper 207 is rotatably connected through the middle of the movable protrusion 205, the rotating scraper 207 is slidably connected to the inside of the cleaning sheet 220, a fixed disc 208 is fixedly connected to the side of the rotating scraper 207 away from the fixed scraper 206, a slot 209 is provided on the outer ring surface of the fixed disc 208, and an electric telescopic rod 219 is fixedly connected to the side of the movable protrusion 205 away from the fixed scraper 206.

[0048] Specifically, when the second moving block 104 and the milling cutter 105 are driven by the existing device to reciprocate, the water pump shaft is milled. However, since the existing technology mainly relies on the chip fluid to prevent the formation of the built-up edge, but the chip fluid cannot completely clean the built-up edge, the second moving block 104 and the milling cutter 105 will stay in a fixed position after a reciprocating motion. At this time, the electric telescopic rod 219 is controlled by the controller to work, and further, it can drive the protective shell 202, the first contact 204 and the guide block 203. All parts directly connected with the movable protrusion 205 move along the guide of the guide block 203 toward the milling device housing 101. At this time, the fixed scraper 206 and the rotating scraper 207 inside the cleaning sheet 220 will extend out of the cleaning sheet 220. At this time, the milling cutter 105 will rotate one hundred and eighty degrees counterclockwise under the drive of the existing device, so that the slope structure of the milling cutter 105 is in direct contact with the fixed scraper 206 and the rotating scraper 207. At this time, the built-up edge attached to the surface of the milling cutter 105 will be cleaned due to the collision.

[0049] At this time, the electric telescopic rod 219 will shrink in the direction away from the milling device housing 101, and further drive all the components directly connected to the moving protrusion 205 except the protective shell 202, the first contact 204 and the guide block 203 to move in the direction away from the milling device housing 101. At this time, the rotating scraper 207 and the fixed scraper 206 will pass through the cleaning sheet 220 and the inside of the milling device housing 101. At the same time, since the cleaning sheet 220 is a sponge structure that is detachably installed on the side wall of the milling device housing 101 and contains There is cutting fluid, and the side walls of the milling device housing 101 with holes that are in direct contact with the fixed scraper 206 are also installed with sponges containing cutting fluid. Therefore, when the fixed scraper 206 and the rotating scraper 207 move away from the milling device housing 101, their surfaces will be cleaned, thereby protecting the cleanliness of the fixed scraper 206 and the rotating scraper 207, avoiding damage to the surface of the milling cutter 105 due to particles remaining on the surface during secondary work, and at the same time extending the service life of the cutter and reducing production costs.

[0050] like Figure 6 As shown, in this embodiment, a square groove 210 is formed on the upper surface of the moving protrusion 205 , a fixing column 211 is fixedly connected to the side wall of the square groove 210 , and a rotating piece 212 is rotatably connected to the outer ring surface of the fixing column 211 .

[0051] like Figure 5 As shown, in this embodiment, an adjusting rod 213 is fixedly connected to the top of the rotating piece 212, a buckle 214 is fixedly connected to the side of the adjusting rod 213 close to the fixed disk 208, a limiting column 215 is fixedly connected to the bottom surface of the side of the adjusting rod 213 away from the buckle 214, a return spring 216 is fixedly connected to the bottom of the limiting column 215, and a cylindrical groove 218 is provided on the upper surface of the movable protrusion 205.

[0052] Specifically, when the staff determines the slope angle of the milling cutter 105, the buckle 214 is manually lifted in the direction away from the moving protrusion 205. At this time, the buckle 214 will synchronously drive the adjustment rod 213 fixedly connected thereto to be lifted, and the adjustment rod 213 is rotatably connected to the fixed column 211 through the rotating piece 212 fixedly connected in the middle thereof. Therefore, when the buckle 214 moves in the direction away from the moving protrusion 205, the adjustment rod 213 will synchronously rotate around the fixed column 211, and further drive the limiting column 215 fixed at the bottom of the side of the adjustment rod 213 away from the buckle 214 to approach the protective shell 202 along the guide of the cylindrical groove 218, and further compress the return spring 216 fixedly connected to the bottom of the limiting column 215 and the bottom of the cylindrical groove 218.

[0053] At this time, the staff manually rotates the fixed disc 208. At the same time, since the fixed disc 208 and the end surface of the rotating scraper 207 close to the moving protrusion 205 are fixedly connected, the rotating scraper 207 will be driven to rotate when the fixed disc 208 rotates. At the same time, since the fixed scraper 206 is fixedly connected to the side of the moving protrusion 205 away from the fixed disc 208, the fixed scraper 206 will not rotate. When the staff manually adjusts the angle between the rotating scraper 207 and the fixed scraper 206 and the milling cutter 1 05 When the angle of the slope structure is adapted, the staff will loosen the buckle 214. At this time, due to the reset of the reset spring 216, the limit column 215 and the adjusting rod 213 fixedly connected to the top of the limit column 215 will rotate around the fixed column 211, and the buckle 214 fixed at one end of the adjusting rod 213 will be driven to rotate synchronously. At this time, the fallen buckle 214 will be engaged with the slot 209 opened on the outer ring surface of the fixed disk 208, so that the entire device can adapt to more milling cutters 105 of different sizes, which can further reduce the production cost.

[0054] like Figure 6 As shown, in this embodiment, a first contact 204 is fixedly connected to the inner side wall of the protective shell 202 , and a second contact 217 is fixedly connected to the side of the movable protrusion 205 .

[0055] Specifically, when the electric telescopic rod 219 is started, it will drive all the components directly connected to the moving protrusion 205 except the protective shell 202, the first contact 204 and the guide block 203 to perform reciprocating linear motion along the guide of the guide block 203. The second contact 217 fixedly connected to the side of the moving protrusion 205 will also perform linear motion synchronously. At this time, the second contact 217 will be against the first contact 204, and the driving source 302 will be controlled to open by the controller.

[0056] like Figure 7 As shown, the blocking protection mechanism 3 of this embodiment includes a fixed shell 301, which is fixedly connected to the side of the milling device shell 101, and an inner cavity is opened inside the fixed shell 301. A driving source 302 is fixedly connected to the bottom of the inner cavity of the fixed shell 301, and the output shaft of the driving source 302 is fixedly connected to a rotating column 303, and the outer ring surface of the rotating column 303 is fixedly connected to a blocking roll plate 304.

[0057] Specifically, when the moving protrusion 205 drives all the components directly connected to the moving protrusion 205 except the protective shell 202, the first contact 204 and the guide block 203 to move along the guide block 203 toward the milling device housing 101, the second contact 217 fixedly connected to the side of the moving protrusion 205 will move synchronously. At this time, when the second contact 217 abuts against the first contact 204, the driving source 302 will be turned on by the controller. When the driving source 302 is started, the rotating column 303 fixedly connected to the output shaft will be driven to rotate counterclockwise through its output shaft. At this time, the blocking plate 304 rolled on the surface of the rotating column 303 will move away from the rotating column 303. 03. When the moving protrusion 205 moves away from the milling device housing 101, since the driving source 302 is a forward and reverse motor, when the second contact 217 and the first contact 204 are again against each other, the driving source 302 will rotate clockwise, and further can drive the rotating column 303 fixedly connected to its output shaft to rotate clockwise, and at the same time can drive the blocking roll 304 fixedly connected to the outer ring surface of the rotating column 303 to move toward the rotating column 303. Since the rotating column 303 is cylindrical and the blocking roll 304 is made of soft material, the blocking roll 304 will also be rolled into a "cylindrical" shape when the rotating column 303 rotates clockwise.

[0058] like Figure 8 As shown, in this embodiment, an iron counterweight 306 is fixedly connected to the bottom of the blocking roll plate 304, a guide groove 305 is provided at one end of the iron counterweight 306, the iron counterweight 306 is slidably connected inside the guide groove 305, and a magnet 307 is fixedly connected to the bottom of the guide groove 305, and the length of the magnet 307 is the same as the length of the inner cavity opened in the milling device housing 101.

[0059] Specifically, when the rotating column 303 rotates clockwise, since the bottom of the blocking roll 304 is fixedly connected to the iron counterweight 306, and the two ends of the iron counterweight 306 slide in the guide groove 305, the blocking roll 304 will be pulled into a plane at this time. When the iron counterweight 306 is against the magnet 307, the magnetism of the magnet 307 will adsorb the iron counterweight 306. At this time, the entire device will become a closed space, thereby preventing the built-up edge from splashing out of the device, further reducing the difficulty of cleaning the waste chips in the later stage, and further improving work efficiency. When the rotating column 303 rotates counterclockwise, the blocking roll 304 and the iron counterweight 306 will be pulled back to the top of the device along the guidance of the guide groove 305.

[0060] Embodiment 2

[0061] like Figures 1 to 8 As shown in the comparative example 1, another embodiment of the present invention is: a milling process for a water pump shaft, the specific steps include:

[0062] Step 1, front process: first pre-process the materials that meet the processing requirements, then place the pre-processed materials into the positioning mechanism, determine the positioning reference during processing to ensure the accuracy of processing, and select appropriate tools and auxiliary tools;

[0063] Step 2, milling process: after the material has gone through the previous process, it is also subjected to three processes of rough machining, semi-finishing and finishing. During the machining process, the milling cutter and the material will generate built-up edge due to the high temperature state, and the built-up edge will affect the subsequent machining accuracy. At this time, the two sets of electric telescopic rods 219 in the cleaning mechanism 2 are started to push out the rotating scraper 207 and the fixed scraper 206, so as to clean the built-up edge on the milling cutter 105;

[0064] Step 3, post-process: clean and rust-proof the pump shaft after the milling process, and perform quality inspection on it. Then assemble and debug it to ensure that all workpieces meet the performance index requirements.

[0065] The specific milling process of step two is as follows: first, when the second moving block 104 and the milling cutter 105 move to the specified position, the electric telescopic rod 219 fixedly connected to the side of the moving protrusion 205 will be started, thereby pushing the rotating scraper 207 and the fixed scraper 206 to extend out of the cleaning sheet 220 through the moving protrusion 205. Since the cleaning sheet 220 is detachable and the material of the cleaning sheet 220 is sponge, the cutting fluid contained in the cleaning sheet 220 will clean the fixed scraper 206 and the rotating scraper 207. After the fixed scraper 206 and the rotating scraper 207 are extended, the milling cutter 105 will rotate counterclockwise one hundred and eighty degrees under the drive of the existing drive so that the head part of the milling cutter 105 can pass between the fixed scraper 206 and the rotating scraper 207, thereby realizing the cleaning of the built-up edge on the milling cutter 105, further improving the accuracy of the device in producing the water pump shaft, and also reducing the production cost.

[0066] Working principle: since the protective shell 202 is detachably connected to the side wall of the milling device housing 101, and the guide block 203 fixed at the bottom of the inner cavity of the protective shell 202 is on the same horizontal line as the guide block 203 installed on the side wall of the placement groove 201, it is mainly used to guide the moving protrusion 205.

[0067] When the second moving block 104 and the milling cutter 105 are driven by the existing device to reciprocate, the water pump shaft is milled. However, since the existing technology mainly relies on the chip fluid to prevent the formation of the built-up edge, but the chip fluid cannot completely clean the built-up edge, the second moving block 104 and the milling cutter 105 will stay in a fixed position after a reciprocating motion. At this time, the electric telescopic rod 219 is controlled by the controller to work, and further, it can drive all the other parts except the protective shell 202, the first contact 204 and the guide block 203. A component directly connected to the movable protrusion 205 moves along the guide of the guide block 203 toward the milling device housing 101. At this time, the fixed scraper 206 and the rotating scraper 207 inside the cleaning sheet 220 will extend out of the cleaning sheet 220. At this time, the milling cutter 105 will rotate one hundred and eighty degrees counterclockwise under the drive of the existing device, so that the slope structure of the milling cutter 105 is in direct contact with the fixed scraper 206 and the rotating scraper 207. At this time, the built-up edge attached to the surface of the milling cutter 105 will be cleaned due to the collision.

[0068] At this time, the electric telescopic rod 219 will shrink in the direction away from the milling device housing 101, and further drive all the components directly connected to the moving protrusion 205 except the protective shell 202, the first contact 204 and the guide block 203 to move in the direction away from the milling device housing 101. At this time, the rotating scraper 207 and the fixed scraper 206 will pass through the cleaning sheet 220 and the inside of the milling device housing 101. At the same time, since the cleaning sheet 220 is a sponge structure that is detachably installed on the side wall of the milling device housing 101, and the inside The side walls of the milling device housing 101 that are in direct contact with the fixed scraper 206 and have holes therein are also installed with sponges containing the chip fluid. Therefore, when the fixed scraper 206 and the rotating scraper 207 move away from the milling device housing 101, their surfaces are cleaned, thereby protecting the cleanliness of the fixed scraper 206 and the rotating scraper 207, avoiding damage to the surface of the milling cutter 105 due to particles remaining on the surface during secondary operation, and at the same time extending the service life of the cutter and reducing production costs.

[0069] In addition, when the staff determines the slope angle of the milling cutter 105, the buckle 214 is manually lifted in the direction away from the moving protrusion 205. At this time, the buckle 214 will synchronously drive the adjustment rod 213 fixedly connected thereto to be lifted, and the adjustment rod 213 is rotatably connected to the fixed column 211 through the rotating piece 212 fixedly connected in the middle thereof. Therefore, when the buckle 214 moves in the direction away from the moving protrusion 205, the adjustment rod 213 will synchronously rotate around the fixed column 211, and further drive the limiting column 215 fixed at the bottom of the side of the adjustment rod 213 away from the buckle 214 to approach the protective shell 202 along the guide of the cylindrical groove 218, and further compress the return spring 216 fixedly connected to the bottom of the limiting column 215 and the bottom of the cylindrical groove 218.

[0070] At this time, the staff manually rotates the fixed disc 208. At the same time, since the fixed disc 208 and the end surface of the rotating scraper 207 close to the moving protrusion 205 are fixedly connected, the rotating scraper 207 will be driven to rotate when the fixed disc 208 rotates. At the same time, since the fixed scraper 206 is fixedly connected to the side of the moving protrusion 205 away from the fixed disc 208, the fixed scraper 206 will not rotate. When the staff manually adjusts the angle between the rotating scraper 207 and the fixed scraper 206 and the milling cutter 1 05 When the angle of the slope structure is adapted, the staff will loosen the buckle 214. At this time, due to the reset of the reset spring 216, the limit column 215 and the adjusting rod 213 fixedly connected to the top of the limit column 215 will rotate around the fixed column 211, and the buckle 214 fixed at one end of the adjusting rod 213 will be driven to rotate synchronously. At this time, the fallen buckle 214 will be engaged with the slot 209 opened on the outer ring surface of the fixed disk 208, so that the entire device can adapt to more milling cutters 105 of different sizes, which can further reduce the production cost.

[0071] When the electric telescopic rod 219 is started, it will drive all the components directly connected to the moving protrusion 205 except the protective shell 202, the first contact 204 and the guide block 203 to perform reciprocating linear motion along the guide of the guide block 203. The second contact 217 fixedly connected to the side of the moving protrusion 205 will also perform linear motion synchronously. At this time, the second contact 217 will be against the first contact 204, and the driving source 302 will be controlled to open through the controller.

[0072] Furthermore, when the moving protrusion 205 drives all the components directly connected to the moving protrusion 205 except the protective shell 202, the first contact 204 and the guide block 203 to move along the guide block 203 toward the milling device housing 101, the second contact 217 fixedly connected to the side of the moving protrusion 205 will move synchronously. At this time, when the second contact 217 abuts against the first contact 204, the driving source 302 will be turned on by the controller. When the driving source 302 is started, the rotating column 303 fixedly connected to its output shaft will be driven to rotate counterclockwise through its output shaft. At this time, the blocking plate 304 rolled on the surface of the rotating column 303 will move away from the rotating column When the movable protrusion 205 moves away from the milling device housing 101, since the driving source 302 is a forward and reverse motor, when the second contact 217 and the first contact 204 collide with each other again, the driving source 302 will rotate clockwise, and further drive the rotating column 303 fixedly connected to its output shaft to rotate clockwise, and at the same time drive the blocking roll 304 fixedly connected to the outer ring surface of the rotating column 303 to move toward the rotating column 303. Since the rotating column 303 is cylindrical and the blocking roll 304 is made of soft material, the blocking roll 304 will also be rolled into a "cylindrical" shape when the rotating column 303 rotates clockwise.

[0073] When the rotating column 303 rotates clockwise, since the bottom of the blocking coil 304 is fixedly connected to the iron counterweight 306, and the two ends of the iron counterweight 306 slide in the guide groove 305, the blocking coil 304 will be pulled into a plane at this time. When the iron counterweight 306 is against the magnet 307, the magnetism of the magnet 307 will adsorb the iron counterweight 306. At this time, the whole device will become a closed space, which can prevent the built-up edge from splashing out of the device, further reduce the difficulty of cleaning the waste chips in the later stage, and further improve the work efficiency. When the rotating column 303 rotates counterclockwise, the blocking coil 304 and the iron counterweight 306 will be pulled back to the top of the device along the guide groove 305.
