Description

Technical Field

[0001] This utility model relates to the field of deburring technology, and more specifically, to a deburring device for an extended milling cutter. Background Technology

[0002] An extended milling cutter is a tool designed to extend the cutting section or the length of the tool holder based on a standard milling cutter. Its significant feature is that it has a longer cutting edge or overall length than a standard milling cutter. It is often used in aerospace, mold manufacturing, automotive parts and other fields. Especially when machining parts with deep cavity structures, it can reduce the number of workpiece clamping times and improve machining efficiency and accuracy.

[0003] Currently, the main function of extended shank milling cutters is to enable the tool to reach deep cavities, narrow grooves, and deep holes in workpieces by increasing the length of the shank, which is difficult for conventional milling cutters to access. This effectively solves the cutting requirements of deep-structured workpieces. For example, when machining deep cavities in mold manufacturing or complex deep hole structures in the aerospace field, it can avoid machining blind spots caused by workpiece structure limitations, reduce the number of workpiece clamping times, and improve machining efficiency.

[0004] However, traditional extended shank end mills do not have deburring capabilities. After processing products, most end mills leave burrs on the product surface, which seriously affects the processing quality. Usually, when removing the burrs, users need to use a special end mill, which reduces the efficiency of product processing. A deburring device for extended end mills is proposed to improve the existing problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a deburring device for an extended milling cutter.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A deburring device for an extended milling cutter includes a mounting bracket, an extended milling cutter is disposed inside the mounting bracket, and a deburring assembly is sleeved on the outer side of the extended milling cutter.

[0008] The extended end mill includes an extended shank, one end of which is connected to the end mill body, and the other end of which passes through a mounting bracket.

[0009] The deburring assembly includes a slewing bearing and a deburring blade for deburring.

[0010] The present invention is further configured such that: a first cylinder and a second cylinder are respectively provided on both sides of the mounting bracket, the output end of the first cylinder is connected to a first mounting block, and the output end of the second cylinder is connected to a second mounting block.

[0011] The present invention is further configured such that: the first mounting block and the second mounting block are respectively connected to both sides of the slewing bearing, and the slewing bearing is sleeved on the outside of the extended handle.

[0012] By adopting the above technical solution, the first cylinder and the second cylinder provide power for the telescopic movement of the deburring blade body. The first cylinder and the second cylinder are connected to the outer ring of the slewing bearing through the first mounting block and the second mounting block, respectively. Therefore, by activating the first cylinder and the second cylinder, the first cylinder and the second cylinder drive the first mounting block and the second mounting block to telescopically move. Under the drive of the first mounting block and the second mounting block, the slewing bearing will also move, and the deburring blade body set in the inner ring of the slewing bearing will also telescopically move, thus achieving the purpose of moving the deburring blade body.

[0013] The present invention is further configured such that: a transmission mechanism is provided on one side of the slewing bearing, the transmission mechanism is used to drive the mounting base to move, and the transmission mechanism is located inside the first mounting block.

[0014] The present invention is further configured such that: a mounting base is provided on the side of the slewing bearing away from the mounting frame, and a deburring blade body is provided inside the mounting base, and the deburring blade body is fixed to the mounting base by bolts.

[0015] The present invention is further configured such that: the deburring knife body includes a handle, and the end of the handle is provided with a bottom edge.

[0016] The present invention is further configured such that: a cutting edge is provided on the side of the cutter shank near the milling cutter body, and a chip removal groove is provided through the middle position of the cutting edge.

[0017] By adopting the above technical solution, the tool shank is bolted to the mounting base, thus connecting the tool shank to the slewing bearing. The bottom cutting edge conforms to the workpiece surface, and its sharp edge can scrape off burrs. Additionally, the cutting edge can scrape off curled or long burrs from the workpiece surface, and the scraped burrs can be discharged through the chip removal groove. In practical applications, the interaction between the cutting edge and the bottom cutting edge allows for multiple burr removal processes, improving the deburring effect. The chip removal groove extends through the middle of the cutting edge, allowing chips generated after deburring to be discharged through the groove, preventing chip accumulation from affecting cutting continuity and reducing chip scraping of the workpiece surface, thus further improving the surface quality after deburring.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] By setting the first cylinder, the second cylinder, the slewing bearing, and the deburring cutter body to work together, the extended milling cutter can directly remove burrs from the surface of the workpiece after machining, thus improving the product processing efficiency.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Please see Figure 1-6 The present invention provides the following technical solution:

[0032] Example 1, see Figure 1A deburring device for an extended milling cutter includes a mounting frame 1, an extended milling cutter 2 is disposed inside the mounting frame 1, and a deburring assembly 3 is sleeved on the outside of the extended milling cutter 2.

[0033] Mounting bracket 1 is used to mount the deburring assembly 3. Mounting bracket 1 is cylindrical in shape. More specifically, mounting bracket 1 is mounted on the milling machine support and fixed with bolts. In specific applications, the extended milling cutter 2 penetrates the mounting bracket 1 and is fixed by the clamping device on the milling machine. The extended milling cutter 2 penetrates the mounting bracket 1 but does not contact the mounting bracket 1. Therefore, in actual operation, the control center of the milling machine controls the extended milling cutter 2 to perform cutting work. When the extended milling cutter 2 is working, the extended milling cutter 2 will not affect the deburring assembly 3 or the mounting bracket 1.

[0034] After the extended milling cutter 2 processes the workpiece, burrs will be generated on the surface of the workpiece. At this time, the deburring assembly 3 is used to process the burrs on the surface of the workpiece.

[0035] See Figures 1-3 The extended end mill 2 includes an extended shank 21, one end of which is connected to the end mill body 22, and the other end of the extended shank 21 passes through the mounting bracket 1.

[0036] The extended end mill 2 is an extended shank end mill, that is, the extended shank 21 is an extended part of the end mill body 22, increasing the overall length of the end mill body 22 to meet its machining requirements.

[0037] See Figures 1-3 The deburring assembly 3 includes a slewing bearing 31 and a deburring blade 37 for deburring.

[0038] See Figures 2-4 A transmission mechanism 38 is provided on one side of the slewing bearing 31. The transmission mechanism 38 is used to drive the mounting base 34 to move. The transmission mechanism 38 is located inside the first mounting block 35.

[0039] See Figures 2-4 A mounting base 34 is provided on the side of the slewing bearing 31 away from the mounting frame 1. A deburring blade body 37 is provided inside the mounting base 34. The deburring blade body 37 is fixed to the mounting base 34 by bolts.

[0040] The slewing bearing 31 includes an inner ring, an outer ring, and a ball bearing positioned between the inner and outer rings. The transmission mechanism 38 is connected to the inner ring of the slewing bearing 31 and can drive the inner ring to rotate. In practical applications, the mounting base 34 is connected to the inner ring of the slewing bearing 31. Since the deburring cutter body 37 is located inside the mounting base 34, when the transmission mechanism 38 is started, the transmission mechanism 38 drives the inner ring of the slewing bearing 31 to rotate. Consequently, the deburring cutter body 37 connected to the inner ring will rotate along with the inner ring. The burrs generated by the workpiece during processing are removed by the rotating deburring cutter body 37, thus achieving the purpose of deburring.

[0041] The transmission mechanism 38 includes a drive motor and a worm gear structure. The worm is connected to the output end of the drive motor, and the worm gear is connected to the inner ring of the slewing bearing 31. Therefore, when the drive motor is started, the drive motor can drive the worm to rotate, and the worm gear meshing with the worm will rotate with the worm. Furthermore, the inner ring will rotate under the drive of the worm gear. By setting the drive motor, the power for the rotation of the inner ring can be provided, thereby achieving the purpose of the inner ring rotation.

[0042] The above structure enables the deburring cutter body 37 to rotate, and achieves the purpose of deburring the workpiece during rotation. However, in practical applications, since the milling cutter is an extended type, a telescopic drive mechanism is required to realize the telescopic movement of the deburring cutter body 37, so that the deburring cutter body 37 can move to the surface of the workpiece to process the burrs on the workpiece surface.

[0043] See Figures 2-4 A first cylinder 32 and a second cylinder 33 are respectively provided on both sides of the mounting bracket 1. The output end of the first cylinder 32 is connected to the first mounting block 35, and the output end of the second cylinder 33 is connected to the second mounting block 36.

[0044] See Figures 2-4 The first mounting block 35 and the second mounting block 36 are respectively connected to both sides of the slewing bearing 31, and the slewing bearing 31 is sleeved on the outside of the extended handle 21.

[0045] By setting the first cylinder 32 and the second cylinder 33 to provide power for the telescopic movement of the deburring blade body 37, and by connecting the first cylinder 32 and the second cylinder 33 to the outer ring of the slewing bearing 31 through the first mounting block 35 and the second mounting block 36, the first cylinder 32 and the second cylinder 33 drive the first mounting block 35 and the second mounting block 36 to telescopically move. Under the drive of the first mounting block 35 and the second mounting block 36, the slewing bearing 31 will also move, and the deburring blade body 37 set in the inner ring of the slewing bearing 31 will also telescopically move, so as to achieve the purpose of moving the deburring blade body 37.

[0046] By setting up the cooperation between the first cylinder 32, the second cylinder 33, the slewing bearing 31, and the deburring cutter body 37, the extended milling cutter 2 can directly remove the burrs on the surface of the workpiece after the workpiece is machined, thus improving the processing efficiency of the product.

[0047] The above process can achieve the purpose of deburring the deburr cutter body 37. In addition, the specific structure of the deburr cutter body 37 needs to be set accordingly.

[0048] See Figure 5 and Figure 6 The deburring blade body 37 includes a handle 371, and a bottom cutting edge 373 is provided at the end of the handle 371.

[0049] See Figure 5 and Figure 6 A cutting edge 372 is provided on the side of the cutter shank 371 near the cutter body 22, and a chip removal groove 374 is provided through the middle of the cutting edge 372.

[0050] The handle 371 is bolted to the inside of the mounting base 34, thus connecting the handle 371 to the slewing bearing 31. By setting the bottom cutting edge 373, the bottom cutting edge 373 can fit against the surface of the workpiece, and the sharp edge of the bottom cutting edge 373 can scrape off and remove burrs from the surface of the workpiece.

[0051] In addition, by setting the cutting edge 372, the curled and long burrs generated on the surface of the workpiece can be scraped off, and the scraped burrs can be discharged through the chip removal groove 374. In practical applications, the burrs on the surface of the workpiece can be processed multiple times by the cooperation of the cutting edge 372 and the bottom edge 373, thereby improving the deburring effect.

[0052] For example, burrs processed by the bottom blade 373 may become tangled and curled. In this case, the curled burrs can be further processed by the cutting blade 372. Burrs processed by the cutting blade 372 may have some missing or short burrs. In this case, the remaining burrs can be further processed by the bottom blade 373. The two work together to improve the deburring effect.

[0053] The chip removal groove 374 extends through the middle of the cutting edge 372. The chips generated after deburring can be discharged through the groove, avoiding chip accumulation that affects the cutting continuity. It can also reduce chip scraping of the workpiece surface and help improve the surface quality after deburring.

[0054] Specifically, firstly, after the extended milling cutter 2 finishes machining the workpiece, the slewing bearing 31 and the first cylinder 32 are started. The slewing bearing 31 and the first cylinder 32 drive the deburring cutter body 37 to move to the workpiece surface through the first mounting block 35 and the second mounting block 36. After the deburring cutter body 37 moves to the workpiece surface, the drive motor of the transmission mechanism 38 is started. The drive motor drives the inner ring of the slewing bearing 31 to rotate, and then the deburring cutter body 37 follows the inner ring of the slewing bearing 31 to rotate. During the rotation, the deburring cutter body 37 processes the burrs on the workpiece surface.

[0055] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
