Technical Field

[0001] This invention belongs to the field of grinding machine technology, specifically relating to a milling cutter type grinding machine and method. Background Technology

[0002] Grinding machines are machine tools that use abrasive wheels to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive wheels and free abrasives such as honing machines, ultra-precision machining tools, belt grinders, lapping machines, and polishing machines.

[0003] Chinese patent CN121670448A discloses an anti-corrosion composite pipe and its grinding equipment. The device includes a base, a first fixing mechanism and a second fixing mechanism fixedly connected to the base, and an anti-corrosion composite pipe fixedly connected between the first and second fixing mechanisms. A driving mechanism is fixedly connected inside the base, and a grinding mechanism is threadedly connected to the driving mechanism. The grinding mechanism has a set of sanding belts located on both sides of the anti-corrosion composite pipe. A suction pipe is also provided on the grinding mechanism, with a flexible hose connected to its bottom, the other end of which is connected to a vacuum cleaner. In the aforementioned application, the workpiece requires manual and continuous positioning and alignment before it can be clamped onto the equipment, making the equipment cumbersome to use and prone to centering misalignment, thus hindering the milling process. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a milling cutter-type grinding machine and method, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a milling cutter type grinding machine and method, including a processing chamber, a control box with the function of controlling the start and stop of the equipment is provided on the outside of the processing chamber, a driving device is provided on the top left side of the processing chamber, an adjustment device is provided on the top right side of the processing chamber, a clamping device is provided on the top of the adjustment device, and a workpiece is provided inside the clamping device. The clamping device is internally connected to a rotating shaft. A motor is fixedly connected to the left side of the rotating shaft, and a gear is fixedly connected to the right side. The right surface of the clamping device is movably connected to racks one and two via a fixed slide rail. Gear one meshes with racks one and two. An arc-shaped positioning strip is fixedly connected to the inner side of racks one and two. The arc-shaped positioning strip has a movable groove inside, and a guide wheel is movably connected inside the movable groove. The outer side of the rotating shaft one on the left is movably connected to the rotating shaft one on the right side via a transmission component. With the arc-shaped positioning strips, during the loading process, after the workpiece is roughly placed between the clamping device and the drive device, the motor is started, causing the arc-shaped positioning strips on both sides to move inward, so that the guide wheel contacts the outer side of the workpiece, thereby automatically positioning and centering the workpiece. This eliminates the need for manual adjustment, making the equipment more convenient to use and improving its working efficiency.

[0006] Preferably, the transmission component includes a belt head 1, a belt 1, a belt head 2, and a telescopic shaft. The belt head 1 is fixedly connected to the outer side of the shaft 1 on the left side. The telescopic shaft is movably connected between the clamping device and the driving device. The belt head 2 is fixedly connected to the outer sides of both ends of the telescopic shaft. The inside of the belt head 1 is movably connected to the belt head 2 through the belt 1.

[0007] Preferably, the fully extended length of the telescopic pivot is consistent with the distance between the clamping device and the driving device when the clamping device moves to its rightmost position, and the center of the arc-shaped positioning strip is parallel to the center of the workpiece's cross-section.

[0008] Preferably, a movable milling cutter is movably connected inside the processing chamber, and a movable grinding device is movably connected inside the processing chamber.

[0009] Preferably, an elastic pad is fixedly connected to the outer surface of the guide wheel, and a milling cutter chip collection assembly is movably connected to the outer side of the movable milling cutter device.

[0010] Preferably, the milling cutter chip collection assembly includes a fixed plate, a telescopic rod, an arc-shaped baffle, a rotating shaft, a torsion spring, a movable baffle, a collection port, a flexible square tube, a collection chamber, and a pull handle. The fixed plate is fixedly connected to the outer side of the rack and pinion, and the telescopic rod is fixedly connected between the fixed plates. The arc-shaped baffle is fixedly connected to the outer side of the rear half of the telescopic rod. The torsion spring is fixedly connected to the outer side of the movable milling cutter, and the rotating shaft is movably connected to the outer side of the torsion spring. The movable baffle is fixedly connected to the outer side of the rotating shaft, and the collection port is fixedly connected to the bottom inner side of the movable baffle. The flexible square tube is fixedly connected to the bottom of the collection port, and the collection chamber is fixedly connected to the bottom of the flexible square tube. The pull handle is fixedly connected to the outer side of the collection chamber. A milling cutter chip collection component is installed. When the movable milling cutter machine processes a workpiece, it generates a large amount of metal chips. If these metal chips enter the movable milling cutter machine, it can easily cause the machine to jam, thus preventing the processing from proceeding smoothly. At this time, the rack moves outward, causing the arc-shaped baffle to drive the movable baffle to rotate inward, so that the collection port fits against the outside of the movable milling cutter machine, allowing the metal chips generated during processing to enter the collection chamber, thereby achieving automatic collection of metal chips.

[0011] Preferably, the collection chamber is internally connected to a drawer, the cross-sectional size of the flexible square tube is smaller than that of the collection chamber, and the top of the processing chamber is movably connected to an auxiliary unloading assembly.

[0012] Preferably, the auxiliary unloading assembly includes a belt head three, a belt two, a belt head four, a fixed plate two, a rotating shaft three, a movable rod, an unloading plate, an arc-shaped plate, and shock-absorbing strips. The belt head three is fixedly connected to the outer side of the telescopic rotating shaft. The fixed plate two is fixedly connected to the top front side of the processing chamber. The rotating shaft three is movably connected inside the fixed plate two. The belt head four is fixedly connected to the left side of the rotating shaft three. The belt head three is movably connected to the belt head four via the belt two. The movable rod is fixedly connected to the outer side of the rotating shaft three. The unloading plate is fixedly connected to the top of the movable rod. The arc-shaped plate is fixedly connected to the top rear side of the unloading plate. Multiple shock-absorbing strips are fixedly connected to the top surface of the unloading plate. With this auxiliary unloading assembly, after the equipment completes processing, the workpiece needs to be manually unloaded. At this time, the motor reverses, causing the telescopic rotating shaft to drive the rotating shaft three to rotate, causing the movable rod to drive the unloading plate to rotate upwards. Then, the clamping device is activated, causing the workpiece to automatically fall onto the surface of the unloading plate, thus realizing the automatic unloading process.

[0013] Preferably, the length of the shock-absorbing strip is less than the length of the unloading plate.

[0014] A method for using a milling cutter type grinder includes the following steps: S1: Place the workpiece roughly between the clamping device and the drive device, start the clamping device and the motor, so that the arc-shaped positioning bar moves inward, so that the workpiece is automatically centered and fixed. S2: Start the movable milling cutter device. At the same time, when the arc-shaped positioning bar moves inward, it causes the arc-shaped baffle to move inward and the movable baffle to rotate, so that the metal chips generated by the movable milling cutter device during operation are collected into the collection chamber through the collection port. S3: After the movable milling cutter completes the processing, start the movable grinding equipment so that the sandpaper can grind along the outside of the workpiece; S4: After the milling process of the workpiece is completed, start the motor to reverse, so that the telescopic shaft reverses and rotates three times. This causes the movable rod to drive the unloading plate to rotate upward. At this time, start the clamping device to move outward, so that the workpiece automatically falls onto the unloading plate, thereby realizing automatic unloading.

[0015] The advantages of this application are: (1) When the equipment is loading, the workpiece is roughly placed between the clamping device and the driving device, and the motor is started to move the arc-shaped positioning strips on both sides inward so that the guide wheel contacts the outer side of the workpiece, thereby automatically positioning and centering the workpiece without the need for manual adjustment, making the equipment more convenient to use and improving the working efficiency of the equipment.

[0016] (2) When the movable milling cutter is used to process the workpiece, a large amount of metal chips will be generated. The metal chips will easily cause the equipment to jam when they enter the movable milling cutter, thus making the processing process impossible. At this time, the rack moves outward, causing the arc baffle to drive the movable baffle to rotate inward, so that the collection port is attached to the outside of the movable milling cutter, so that the metal chips generated during processing enter the collection chamber, thereby realizing the automatic collection of metal chips.

[0017] (3) After the equipment completes the processing, the workpiece needs to be unloaded manually. At this time, the motor reverses and the telescopic shaft drives the shaft to rotate, which in turn drives the moving rod to rotate the unloading plate upward. At this time, the clamping device is started, so that the workpiece automatically falls to the surface of the unloading plate, thereby realizing the automatic unloading process of the workpiece.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-4As shown, a milling cutter type grinding machine and method include a processing chamber 100. A control box 200 with the function of controlling the start and stop of the equipment is provided on the outside of the processing chamber 100. A drive device 300 is provided on the top left side of the processing chamber 100. The drive device 300 drives the workpiece 800 to rotate. An adjustment device 400 is provided on the top right side of the processing chamber 100. A clamping device 500 is provided on the top of the adjustment device 400. When the clamping device 500 is started, the workpiece 800 is clamped by the clamping device 500, thereby achieving initial fixation. The workpiece 800 is provided inside the clamping device 500. The clamping device 500 has a rotating shaft 901 internally connected to it. A motor is fixedly connected to the left side of the rotating shaft 901, and a gear 902 is fixedly connected to the right side of the rotating shaft 901. The right side surface of the clamping device 500 is movably connected to rack 903 and rack 905 via a fixed slide rail 904. Gear 902 meshes with rack 903 and rack 905. An arc-shaped positioning strip 906 is fixedly connected to the inner side of rack 903 and rack 905. An movable groove 907 is opened inside the arc-shaped positioning strip 906. A guide wheel 908 is movably connected inside the movable groove 907. The outer side of the left rotating shaft 901 is movably connected to the right rotating shaft 901 via a transmission component.

[0022] The transmission components include a belt head 909, a belt 910, a belt head 911, and a telescopic shaft 912. The belt head 909 is fixedly connected to the outer side of the left-side shaft 901. The telescopic shaft 912 is movably connected between the clamping device 500 and the driving device 300. The telescopic shaft 912 is provided so that the movement of the clamping device 500 will not affect the rotation of the telescopic shaft 912. The belt head 911 is fixedly connected to the outer sides of both ends of the telescopic shaft 912. The inside of the belt head 909 is movably connected to the belt head 911 through the belt 910.

[0023] The fully extended length of the telescopic pivot 912 is consistent with the distance between the clamping device 500 and the drive device 300 when the clamping device 500 moves to its rightmost position, and the center of the cross-section of the arc-shaped positioning bar 906 is parallel to the center of the cross-section of the workpiece 800.

[0024] The machining chamber 100 is movably connected to a movable milling cutter 600, which allows the outer side of the workpiece 800 to be machined. The machining chamber 100 is also movably connected to a movable grinding device 700, which allows the outer side of the workpiece 800 to be ground.

[0025] When the workpiece 800 is roughly placed between the clamping device 500 and the driving device 300 during the loading process, the motor is started, causing the arc-shaped positioning bars 906 on both sides to move inward, so that the guide wheel 908 contacts the outer side of the workpiece 800, thereby automatically positioning and centering the workpiece 800 without the need for manual adjustment, making the equipment more convenient to use and improving the equipment's working efficiency.

[0026] In practical use, the workpiece 800 is roughly placed between the clamping device 500 and the driving device 300. The adjusting device 400 and the clamping device 500 are started to initially clamp the workpiece 800. At this time, the motor is started, causing the rotating shaft 901 to rotate. The gear 902 follows the rotating shaft 901, causing the rack 903 and rack 905 to move inward under the drive of the gear 902. This causes the arc-shaped positioning bar 906 to move inward, bringing the guide wheel 908 into contact with the outer side of the workpiece 800. Simultaneously, the rotating shaft 901... 901 drives the belt head 909 to rotate, which in turn drives the belt head 911 to rotate via belt 910. This causes the telescopic shaft 912 to rotate, which in turn causes the right-side shaft 901 to rotate. This, in turn, causes the right-side gear 902 to rotate, which in turn drives the right-side racks 903 and 905 to move inward. This causes the right-side arc-shaped positioning bar 906 to move inward, thus automatically positioning and centering the workpiece 800 without the need for manual adjustment. This makes the equipment more convenient to use and improves its working efficiency.

[0027] Example 2, as Figures 5-6 As shown, based on Embodiment 1, the milling cutter chip collection assembly 1000 includes a fixed plate 1001, a telescopic rod 1002, an arc-shaped baffle 1003, a rotating shaft 1004, a torsion spring 1005, a movable baffle 1006, a collection port 1007, a flexible square tube 1008, a collection bin 1009, and a pull handle 1010. The fixed plate 1001 is fixedly connected to the outer side of the rack 905. The telescopic rod 1002 is fixedly connected between the fixed plates 1001. The arc-shaped baffle 1003 is fixedly connected to the outer side of the rear half of the telescopic rod 1002. The torsion spring 1005 is fixedly connected to the outer side of the movable milling cutter device 600. The torsion spring 1005 is provided to allow the movable baffle to... Plate 1006 can automatically reset. A rotating shaft 1004 is movably connected to the outer side of torsion spring 1005. A movable baffle 1006 is fixedly connected to the outer side of rotating shaft 1004. A collection port 1007 is fixedly connected to the bottom inner side of movable baffle 1006. A flexible square tube 1008 is fixedly connected to the bottom of collection port 1007. The flexible square tube 1008 is provided so that the rotation of movable baffle 1006 will not affect the collection of metal waste in collection port 1007. A collection chamber 1009 is fixedly connected to the bottom of flexible square tube 1008. A pull handle 1010 is fixedly connected to the outer side of collection chamber 1009. The pull handle 1010 is provided to make cleaning inside collection chamber 1009 more convenient.

[0028] The collection bin 1009 has a drawer internally connected to it. The cross-sectional size of the flexible square tube 1008 is smaller than that of the collection bin 1009. The top of the processing bin 100 is movably connected to an auxiliary unloading assembly 1100.

[0029] A milling cutter chip collection component 1000 is provided. When the movable milling cutter device 600 processes the workpiece 800, a large amount of metal chips are generated. If the metal chips enter the movable milling cutter device 600, the device may jam, thus preventing the processing from proceeding smoothly. At this time, the rack 2 905 moves outward, causing the arc-shaped baffle 1003 to drive the movable baffle 1006 to rotate inward, so that the collection port 1007 fits against the outside of the movable milling cutter device 600, allowing the metal chips generated during processing to enter the collection chamber 1009, thereby realizing the automatic collection of metal chips.

[0030] When the aforementioned equipment is in use, the movable milling cutter 600 generates a large amount of metal chips when machining the workpiece 800. These metal chips can easily cause the equipment to jam if they enter the movable milling cutter 600, thus hindering the machining process. At this time, rack 2 905 moves inward, causing rack 2 905 to drive telescopic rod 1002 inward via fixed plate 1001. This causes arc-shaped baffle 1003 to drive movable baffle 1006 to rotate inward, causing rotating shaft 2 1004 to rotate, thus collecting... The nozzle 1007 is attached to the outside of the movable milling cutter 600, allowing the metal chips generated during processing to enter the collection chamber 1009, thereby achieving automatic collection of metal chips. After the equipment completes processing, the arc-shaped baffle 1003 separates from the movable baffle 1006. At this time, the torsion spring 1005 converts its own elastic potential energy into the kinetic energy of the movable baffle 1006, causing the movable baffle 1006 to automatically reset, allowing the metal chips generated during processing to enter the collection chamber 1009, thereby achieving automatic collection of metal chips.

[0031] Example 3, as Figures 7-8As shown, based on Embodiment 2, the auxiliary unloading assembly 1100 includes a belt head 3 1101, a belt 2 1102, a belt head 4 1103, a fixing plate 2 1104, a rotating shaft 3 1105, a movable rod 1106, an unloading plate 1107, an arc plate 1108, and a shock-absorbing strip 1109. The belt head 3 1101 is fixedly connected to the outer side of the telescopic rotating shaft 912. The fixing plate 2 1104 is fixedly connected to the top front side of the processing chamber 100. The rotating shaft 3 1105 is movably connected inside the fixing plate 2 1104. The belt head 4 1103 is fixedly connected to the left side of the rotating shaft 3 1105. The belt head 3 1101 is connected to the inside of the belt head 3 1101 via a belt... Belt 2 1102 is movably connected to belt head 4 1103. A movable rod 1106 is fixedly connected to the outer side of shaft 3 1105. A discharge plate 1107 is fixedly connected to the top of movable rod 1106. An arc plate 1108 is fixedly connected to the top rear side of discharge plate 1107. The arc plate 1108 is set so that the workpiece 800 is guided by the arc plate 1108 after processing. Multiple shock-absorbing strips 1109 are fixedly connected to the top surface of discharge plate 1107. The shock-absorbing strips 1109 are set so that the collision of workpiece 800 falling onto the surface of discharge plate 1107 is mitigated and workpiece 800 is protected. The length of the shock-absorbing strips 1109 is less than the length of discharge plate 1107.

[0032] An auxiliary unloading component 1100 is set up. After the equipment completes processing, the workpiece 800 needs to be unloaded manually. At this time, the motor reverses, causing the telescopic shaft 912 to drive the shaft three 1105 to rotate, causing the movable rod 1106 to drive the unloading plate 1107 to rotate upward. At this time, the clamping device 500 is activated, so that the workpiece 800 automatically falls onto the surface of the unloading plate 1107, thereby realizing the automatic unloading process of the workpiece 800.

[0033] In practical use, after the equipment has finished processing, the workpiece 800 needs to be manually unloaded. At this time, the motor is started in reverse, causing gear 902 to reverse, which in turn causes the telescopic shaft 912 to rotate in the opposite direction. This causes belt head 1101 to rotate with the telescopic shaft 912, and belt head 1101 drives belt head 1103 to rotate via belt 1102. This causes shaft 1105 to rotate, and the movable rod 1106 to rotate upward with shaft 1105. This causes the unloading plate 1107 to rotate upward. At this time, the clamping device 500 is started, and the workpiece 800 automatically falls onto the surface of the unloading plate 1107, thus realizing the automatic unloading process of workpiece 800, making the equipment more convenient to use and saving manpower.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
