Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting edge processing technology, and more specifically, it relates to a cutting edge processing device for a straight shank end mill. Background Technology
[0002] Straight shank end mills are a common type of end mill. Their shank is a cylindrical straight shank structure, which is clamped by the spring collet or drill chuck of the machine tool spindle. They are easy to clamp and have good coaxiality. Because of their simple shank structure and strong versatility, straight shank end mills are widely used in mold manufacturing, instrumentation, parts processing and other fields, and play an important role, especially in small and medium-sized milling processes on CNC milling machines and machining centers.
[0003] Currently, if a straight shank end mill experiences extensive wear on its cutting edge after a period of use, the end mill needs to be re-sharpened. The re-sharpening process for an end mill consists of three steps: first, grind the worn area on the end face of the end mill flat; second, after grinding, re-groove the end mill; and finally, after grooving the end mill, re-grind the clearance angle of the end mill.
[0004] However, when existing end mills wear out, they are manually ground, grooved, and re-grinded by operators. During this process, hand tremors during manual operation lead to uneven feed rates, which in turn affects the consistency of the cutting edge. A cutting edge machining device for straight shank 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 cutting edge machining device for a straight shank end mill.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A cutting edge machining device for a straight shank end mill includes a transfer assembly, a machining assembly disposed above the transfer assembly, and a milling cutter to be machined disposed above the machining assembly.
[0008] The transfer assembly includes a worktable, a first electric slide rail is provided on the top of the worktable, a second electric slide rail is provided above the first electric slide rail, the second electric slide rail is connected to the worktable by a bracket, a third electric slide rail is provided on one side of the second electric slide rail, and a milling cutter electric chuck is provided on the side of the third electric slide rail away from the second electric slide rail, the milling cutter electric chuck is used to hold the milling cutter to be processed.
[0009] The processing assembly includes a turntable mechanism, with a second processing mechanism and a third processing mechanism respectively arranged above the turntable mechanism, and a first processing mechanism arranged on one side of the turntable mechanism.
[0010] By adopting the above technical solution, the electric chuck for milling cutters is driven by an electric motor to clamp and release the milling cutter to be processed. The second electric slide rail drives the third electric slide rail, the electric chuck for milling cutters, and the milling cutter to be processed to move horizontally, thereby adjusting the left and right position of the milling cutter to be processed. The third electric slide rail drives the electric chuck for milling cutters and the milling cutter to move vertically, thereby adjusting the up and down position of the milling cutter to be processed. By adjusting the position of the milling cutter to be processed, the processing requirements of the milling cutter to be processed can be met. The first electric slide rail drives the processing components to move horizontally, thereby adjusting the horizontal position of the processing components to meet the processing requirements of different workstations. The second and third processing mechanisms are both composed of processing motors and grinding wheels. The grinding wheels and processing motors can be adjusted according to the corresponding processing requirements. The processing motor drives the grinding wheel to move, thereby processing the milling cutter to be processed. The turntable mechanism is used to adjust the position of the second and third processing mechanisms to meet the requirements of multi-directional grooving and grinding of the back angle of the second and third processing mechanisms. The first processing mechanism is used to grind the end of the milling cutter to be processed, in preparation for subsequent sharpening.
[0011] The present invention is further configured such that: a placement seat is provided on the top of the turntable mechanism, and the second processing mechanism and the third processing mechanism are disposed opposite to each other on the top of the placement seat.
[0012] The present invention is further configured such that: a mounting plate is provided on the top of the first electric slide rail, and the turntable mechanism and the first processing mechanism are located on the top of the mounting plate.
[0013] The present invention is further configured such that: the turntable mechanism includes a base, the base is disposed on the top of the mounting plate, and a guide wheel assembly is arranged around the top of the base.
[0014] The present invention is further configured such that: an annular rack is provided at the middle position of the guide wheel assembly, the annular rack is provided at the top of the base, and a turntable is provided above the annular rack.
[0015] The present invention is further configured such that the turntable slides relative to the guide wheel assembly, and a rotating motor is provided at the bottom of the turntable.
[0016] The present invention is further configured such that: the output end of the rotating motor is connected to a gear, and the gear meshes with a ring rack.
[0017] By adopting the above technical solution, a rotating motor drives the gear to move along the ring rack. The ring shape of the ring rack provides a clear motion trajectory for the gear, making the transmission process more stable and reducing the uncertainty of the motion. By setting a guide wheel group to limit the turntable, while allowing the turntable to slide relative to the guide wheel group, this design ensures that the turntable will not deviate from the predetermined motion path, and provides the necessary degree of freedom for the rotation of the turntable, ensuring the normal operation of the entire device.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] By setting up a turntable mechanism, a first machining mechanism, a second machining mechanism, and a third machining mechanism in conjunction with the first electric slide rail, the intelligent machining of the milling cutter to be machined, which is held on the electric chuck of the milling cutter, can be realized. This solves the problem caused by hand tremors during manual operation and improves machining efficiency and accuracy. Attached Figure Description

[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 1 A cutting edge machining device for a straight shank end mill includes a transfer assembly 1, a machining assembly 2 disposed above the transfer assembly 1, and a milling cutter 3 to be machined disposed above the machining assembly 2.
[0033] See Figure 1 and Figure 2 The transfer assembly 1 includes a worktable 11. A first electric slide rail 12 is provided on the top of the worktable 11. A second electric slide rail 13 is provided above the first electric slide rail 12. The second electric slide rail 13 is connected to the worktable 11 by a bracket. A third electric slide rail 14 is provided on one side of the second electric slide rail 13. A milling cutter electric chuck 15 is provided on the side of the third electric slide rail 14 away from the second electric slide rail 13. The milling cutter electric chuck 15 is used to clamp the milling cutter 3 to be processed.
[0034] The electric chuck 15 for milling cutters is driven by an electric motor to clamp and release the milling cutter 3 to be processed. The second electric slide rail 13 drives the third electric slide rail 14, the electric chuck 15 for milling cutters, and the milling cutter 3 to be processed to move horizontally, thereby adjusting the left and right position of the milling cutter 3 to be processed. The third electric slide rail 14 drives the electric chuck 15 for milling cutters and the milling cutter 3 to move vertically, thereby adjusting the up and down position of the milling cutter 3 to be processed. By adjusting the position of the milling cutter 3 to be processed, the processing requirements of the milling cutter 3 to be processed can be met. The first electric slide rail 12 drives the processing component 2 to move horizontally, thereby adjusting the horizontal position of the processing component 2 to meet the processing requirements of different workstations.
[0035] The workflow of transfer component 1 is as follows:
[0036] First, the milling cutter 3 to be processed is clamped and stabilized by the electric chuck 15. Second, the second electric slide rail 13 is activated, which drives the third electric slide rail 14 and the electric chuck 15 on one side of the third electric slide rail 14 and the milling cutter 3 to be processed horizontally to the position of the processing component 2. Then, the third electric slide rail 14 is activated again, which drives the electric chuck 15 and the milling cutter 3 to be processed vertically downward to the processing position. Finally, the processing component 2 completes the processing of the milling cutter 3.
[0037] See Figure 2 and Figure 3 The processing component 2 includes a turntable mechanism 21, with a second processing mechanism 23 and a third processing mechanism 24 respectively arranged above the turntable mechanism 21, and a first processing mechanism 22 arranged on one side of the turntable mechanism 21.
[0038] The second machining mechanism 23 and the third machining mechanism 24 are both composed of a machining motor and a grinding wheel. The grinding wheel and the machining motor can be adjusted according to the corresponding machining requirements. The machining motor drives the grinding wheel to move, which can realize the machining of the milling cutter 3 to be machined.
[0039] The turntable mechanism 21 is used to adjust the positions of the second machining mechanism 23 and the third machining mechanism 24 to meet the needs of the second machining mechanism 23 and the third machining mechanism 24 for multi-directional grooving and grinding of the back angle. The first machining mechanism 22 is used to grind the end of the milling cutter 3 to be processed, in preparation for subsequent sharpening.
[0040] See Figure 3 The top of the turntable mechanism 21 is provided with a placement seat 25, and the second processing mechanism 23 and the third processing mechanism 24 are respectively disposed on the top of the placement seat 25.
[0041] See Figure 2 and Figure 3 The top of the first electric slide rail 12 is provided with a mounting plate, and the turntable mechanism 21 and the first processing mechanism 22 are located on the top of the mounting plate.
[0042] The machining process of machining component 2 for the milling cutter 3 to be machined is as follows:
[0043] First, the milling cutter 3 to be processed is clamped by the electric chuck 15. Then, the third electric slide rail 14 is activated, which moves the electric chuck 15 and the milling cutter 3 vertically to a higher position to avoid collision with the first machining mechanism 22 in the subsequent process. Next, the second electric slide rail 13 is activated, which moves the third electric slide rail 14, the electric chuck 15, and the milling cutter 3 horizontally above the first machining mechanism 22. Then, the first electric slide rail 12 is activated, which moves the first machining mechanism 22 horizontally to directly below the milling cutter 3. The third electric slide rail 14 is activated again, which moves the milling cutter 3 vertically downward to a position where it contacts the first machining mechanism 22. Finally, the machining motor of the first machining mechanism 22 is activated, which drives the grinding wheel to grind the end of the milling cutter 3.
[0044] After the end of the milling cutter 3 is ground flat, the third electric slide rail 14 is activated to move the milling cutter 3 vertically upward. Then, the first electric slide rail 12 is activated, which moves the first machining mechanism 22 horizontally until the second machining mechanism 23 and the third machining mechanism 24 move to the machining position. When the second machining mechanism 23 and the third machining mechanism 24 reach the machining position, the second electric slide rail 13 is activated to move the milling cutter 3 horizontally, and the third electric slide rail 14 is activated to move the milling cutter 3 vertically downward until it contacts the second machining mechanism 23. After the second machining mechanism 23 contacts the milling cutter 3, the machining motor of the second machining mechanism 23 is activated. The grinding wheel is driven to rotate. At this time, the third electric slide rail 14 is started again to continue to drive the milling cutter 3 to be processed to move vertically downward. The grinding wheel begins to groove the milling cutter 3 to be processed. After the second processing mechanism 23 has finished processing the milling cutter 3 to be processed, the milling cutter 3 to be processed is driven to move horizontally through the second electric slide rail 13 and to move vertically through the third electric slide rail 14. Finally, the milling cutter 3 to be processed comes into contact with the third processing mechanism 24. At this time, the third processing mechanism 24 starts its processing motor, which drives its grinding wheel to rotate. The third electric slide rail 14 is started again to continue to drive the milling cutter 3 to move vertically downward. The grinding wheel begins to groove the milling cutter 3 to be processed.
[0045] After the two sets of grooves at the bottom of the milling cutter 3 are opened, the turntable mechanism 21 drives the second machining mechanism 23 and the third machining mechanism 24 to rotate 90°. Then, the milling cutter 3 is opened with the other two sets of grooves through the above process. After the four sets of grooves are opened, the angle of the second machining mechanism 23 and the third machining mechanism 24 is adjusted by rotating the turntable mechanism 21. The back angle of the milling cutter 3 is then ground by the second machining mechanism 23 and the third machining mechanism 24. When the back angle of the milling cutter 3 is ground, the milling of the milling cutter 3 is completed.
[0046] By setting up a turntable mechanism 21, a first machining mechanism 22, a second machining mechanism 23, and a third machining mechanism 24 in conjunction with a first electric slide rail 12, a second electric slide rail 13, and a third electric slide rail 14, intelligent machining of the milling cutter 3 to be machined, which is clamped on the electric chuck 15, can be realized. This solves the problem caused by hand tremors during manual operation and improves machining efficiency and accuracy.
[0047] In the above process, the turntable mechanism 21 needs to drive the second machining mechanism 23 and the third machining mechanism 24 to rotate, so that the second machining mechanism 23 and the third machining mechanism 24 can perform grooving and back angle grinding on the milling cutter 3 to be machined. The specific structure of the turntable mechanism 21 is as follows:
[0048] See Figures 4-6 The turntable mechanism 21 includes a base 211, which is located on the top of the mounting plate, and a guide wheel assembly 212 is arranged around the top of the base 211.
[0049] See Figures 4-6 A ring rack 215 is provided in the middle of the guide wheel assembly 212. The ring rack 215 is located on the top of the base 211, and a turntable 213 is provided above the ring rack 215.
[0050] See Figures 4-6 The turntable 213 slides relative to the guide wheel assembly 212, and a rotating motor 214 is provided at the bottom of the turntable 213.
[0051] See Figures 4-6 The output end of the rotating motor 214 is connected to a gear 216, which meshes with the ring rack 215.
[0052] The motion flow of the turntable mechanism 21 is as follows:
[0053] First, start the rotating motor 214. The rotating motor 214 drives the gear 216 to move along the annular rack 215. Since the annular rack 215 is set in a ring, the gear 216 moves along the annular track of the annular rack 215. Since the guide wheel assembly 212 limits the turntable 213 and the turntable 213 slides relative to the guide wheel assembly 212, the annular rack 215 and the turntable 213 can be rotated under the drive of the gear 216. The rotation of the turntable 213 can realize the rotation of the placement seat 25.
[0054] By setting the rotating motor 214 to drive the gear 216 to move along the annular rack 215, the annular configuration of the annular rack 215 provides the gear 216 with a clear motion trajectory, making the transmission process more stable and reducing the uncertainty of motion.
[0055] By setting the guide wheel assembly 212 to limit the turntable 213, while allowing the turntable 213 to slide relative to the guide wheel assembly 212, this design ensures that the turntable 213 will not deviate from the predetermined movement path, and provides the necessary degree of freedom for the rotation of the turntable 213, thus ensuring the normal operation of the entire device.
[0056] 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.
