Description

Technical Field

[0001] This utility model belongs to the field of steel milling cutter technology, specifically relating to a deburring device for the cutting edge of a coated mold steel milling cutter. Background Technology

[0002] Steel end mills are tools specifically designed for machining steel and are widely used in the metalworking industry. Steel end mills are typically made of materials such as high-speed steel (HSS), cemented carbide, or diamond. They possess high wear resistance and heat resistance, resulting in a long service life and high machining efficiency. During the machining process with steel end mills, burrs can be generated due to variations in tool material, workpiece material, cutting parameters, cooling and lubrication, equipment precision, and machining methods. Burrs and flash can affect the surface roughness of parts. During steel end mill machining, burrs and flash may leave protrusions or depressions on the part surface, increasing surface roughness and affecting the part's appearance and performance.

[0003] A known authorized patent with application number CN202420086132.X discloses a deburring device for machining metal-ceramic milling cutters. The device includes a base, a motor, a robotic arm component, and a linear guide rail fixing seat. Multiple linear guide rails are mounted on the top of the linear guide rails. A slider is mounted on the top of the linear guide rails. A semi-circular clamp fixing seat is mounted on the top of the slider. A semi-circular clamp is mounted on the top of the semi-circular clamp fixing seat. One end of the semi-circular clamp has a fan-shaped boss. One end of the fan-shaped boss has a wave-shaped clamping piece. The vertical projection of the wave-shaped clamping piece is wavy. With this structure, the prior art can firmly hold the metal-ceramic milling cutter when the grinding component rubs against it. Furthermore, the motor can drive a triangular turntable to adjust the position of the semi-circular clamp, thereby fixing metal-ceramic milling cutters of different sizes and further improving the working efficiency of the deburring device for machining metal-ceramic milling cutters.

[0004] However, in implementing the relevant technology, the following problems were found with the above technical solution: the device is difficult to grind irregularly shaped steel milling cutters. During grinding, the operator needs to spend a lot of time adjusting the grinding components, which makes it difficult for the device to completely remove burrs from irregularly shaped steel milling cutters.

[0005] Therefore, a deburring device for the cutting edge of coated mold steel milling cutters is proposed to solve the above problems. Utility Model Content

[0029] Implementation

[0030] Please see Figure 1 -5. A deburring device for the cutting edge of a coated mold steel milling cutter, comprising:

[0031] Fixed plate 1 and support frame 2;

[0032] A grinding unit is fixedly installed inside the fixed plate 1 for grinding irregularly shaped steel milling cutters;

[0033] A height adjustment unit, fixedly installed inside the support frame 2, is used to adjust the height of the steel milling cutter;

[0034] A clamping unit located inside the height adjustment unit is used to clamp a steel milling cutter;

[0035] The grinding unit includes a fixed frame 3 fixedly installed on the top of the fixed plate 1, a first motor 4 fixedly installed inside the fixed frame 3, a first pulley 5 fixedly installed at the output end of the first motor 4, a fixed bearing 6 fixedly installed inside the fixed plate 1, a drive shaft 7 fixedly installed inside the fixed bearing 6 through the fixed plate 1, a second pulley 8 fixedly installed at the bottom end of the drive shaft 7, a transmission belt 9 sleeved on the first pulley 5 and the second pulley 8, a drive platform 10 fixedly installed on the top of the drive shaft 7, a limiting rod 11 fixedly installed on the top surface of the drive platform 10, a grinding cylinder 12 set on the top of the drive platform 10 and engaged with the limiting rod 11, and a limiting groove 13 opened on the outer surface of the grinding cylinder 12. The grinding cylinder 12 is filled with abrasive material made of a mixture of quartz sand and ceramic particles.

[0036] The technical solution provided in this embodiment is as follows: In use, firstly, the steel end mill that needs to be deburred is placed inside the slot 19. Then, the handle 23 is rotated to rotate the threaded rod 21. The two clamping plates 18 are brought closer together by the baffle 22. The steel end mill is then clamped by the slot 19 and the rubber pad 20. Then, the first motor 4 is started to rotate the first pulley 5, which drives the second pulley 8 to rotate through the transmission belt 9. This rotates the drive shaft 7 and the drive table 10, which in turn rotates the grinding cylinder 12. Then, the second motor 14 is started to rotate the lead screw 16, which causes the slider 24 to slide downward through the slide rod 15. This allows the steel end mill to extend into the interior of the rotating abrasive inside the grinding cylinder 12, thereby allowing the abrasive to grind the burrs on the steel end mill.

[0037] Furthermore, the height adjustment unit includes a second motor 14 fixedly installed inside the bottom surface of the support frame 2, two slide rods 15 installed opposite to each other inside the support frame 2, a lead screw 16 fixedly installed at the output end of the second motor 14, and a slider 24 slidably installed outside the two slide rods 15. The slider 24 is threadedly connected to the lead screw 16, and the top end of the lead screw 16 is inserted into the interior of the support frame 2 and rotatably connected to the support frame 2.

[0038] Specifically, by sliding the slider 24 outside the two sliders 15, the slider 24 can be prevented from rotating when it is moved by the lead screw 16, thus preventing it from affecting the movement effect.

[0039] Furthermore, the clamping unit includes a connecting block 17 fixedly installed on the side of the slider 24 near the grinding cylinder 12, two clamping plates 18 fixedly installed on one side of the connecting block 17, a slot 19 opened inside the two clamping plates 18, a rubber pad 20 fixedly installed inside the slot 19, a threaded rod 21 passing through one clamping plate 18 and threadedly connected to the other clamping plate 18, a baffle 22 fixedly installed at one end of the threaded rod 21, and a rotating handle 23 fixedly installed at the other end of the threaded rod 21.

[0040] Specifically, by threading the threaded rod 21 to another clamping plate 18, and fixing a baffle 22 at one end of the threaded rod 21, the two clamping plates 18 can be brought closer together by the baffle 22 when the threaded rod 21 is rotated, and then the steel end mill is clamped by the slot 19.

[0041] Furthermore, the slot 19 is located directly above the grinding cylinder 12, and the slot 19 is semi-circular.

[0042] Specifically, by setting the slot 19 directly above the grinding cylinder 12, the steel end mill can be ground by the abrasive inside the grinding cylinder 12 to remove burrs when the slot 19 holds the steel end mill.

[0043] Furthermore, both clamping plates 18 are made of beryllium copper, and the distance between the two clamping plates 18 is one centimeter.

[0044] Specifically, by setting the distance between the two clamping plates 18 made of beryllium copper to one centimeter, the metal fatigue generated by the clamping plates 18 during bending can be reduced when the two clamping plates 18 are bent by the threaded rod 21 and the baffle 22.

[0045] Furthermore, the number of limiting rods 11 is equal to the number of limiting grooves 13, and the limiting rods 11 and the limiting grooves 13 are slidably connected.

[0046] Specifically, by making the number of limiting rods 11 equal to the number of limiting grooves 13, and by making the limiting rods 11 and the limiting grooves 13 slidably connected, the grinding cylinder 12 can be locked on the top of the drive table 10 by the limiting rods 11 and the limiting grooves 13.

[0047] Furthermore, multiple support feet are fixedly installed on the bottom of the fixing plate 1, and the multiple support feet are installed in a rectangular array on the bottom of the fixing plate 1.

[0048] Specifically, by fixing multiple support feet in a rectangular array to the bottom of the fixed plate 1, support can be provided for the deburring device, increasing the stability of the device.

[0049] Furthermore, the diameter of the abrasive material inside the grinding cylinder 12 is two millimeters.

[0050] Specifically, by setting the diameter of the abrasive inside the grinding cylinder 12 to two millimeters, the abrasive can grind the grooves on the steel end mill.

[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
