Description

Technical Field

[0001] The invention relates to the technical field of end milling equipment, and in particular to an end milling machine. Background Art

[0002] End milling machine is a special machine tool used for end milling, which is used in metal processing, machinery manufacturing and mold processing. It mainly cuts by rotating the end face or side of the milling cutter in contact with the workpiece, and can achieve various processing methods such as plane milling, contour processing, hole processing, step processing, chamfering, etc. In the processing of aluminum alloy doors and windows, it is often necessary to use an end milling machine to process the end of the profile.

[0003] The patent document with the announcement number CN218080596U discloses a fixed-length end milling device for aluminum profiles, including a base, a sliding frame symmetrically arranged on the upper side of the base, a driving motor arranged on one side of the sliding frame, a horizontal servo mechanism arranged at the lower part of the sliding frame, a vertical servo mechanism arranged on the horizontal servo mechanism, an end milling motor arranged on the opposite side of the vertical servo mechanism, a milling cutter arranged at the output end of the end milling motor, a lifting mechanism arranged at the lower side of the milling cutter at the upper part of the sliding frame, and a pressing mechanism arranged on the upper side of the lifting mechanism. Mechanism, a pressing plate is arranged at the lower side of the pressing mechanism, and a pressing cylinder is arranged at the center of the upper side of the pressing plate. Through the arranged base, sliding frame, horizontal servo mechanism, vertical servo mechanism, driving motor, end milling motor and milling cutter, when the aluminum profile end milling device is in use, the driving motor drives the sliding frame to move precisely on the base, so that the distance between the two sliding frames meets the fixed length distance of the aluminum profile, and then the end milling motor drives the milling cutter to perform fixed-length end milling on batches of aluminum profiles according to the fixed length distance, so that the end milling quality of the aluminum profile meets the requirements.

[0004] However, the following problems still exist in this scheme: when the profiles of aluminum alloy doors and windows are end-milled, the same end-milling operation is often required at both ends of the profiles. However, in the above scheme, the aluminum profile cannot be automatically turned around after end-milling, and only one end of the aluminum profile can be processed. It needs to be disassembled and turned over again before further processing can be carried out, which is troublesome and inconvenient, and is not conducive to the rapid processing of aluminum profiles. Summary of the invention

[0005] The present invention provides an end milling machine, aiming to solve the problem in the related art that the aluminum profile cannot be automatically turned around after end milling, and can only be processed on one end of the aluminum profile, and needs to be disassembled and turned over again before further processing.

[0006] The end milling machine of the present invention comprises a machine body, an end milling cutter is arranged inside the machine body, a support table is arranged on one side of the machine body, a positioning assembly is arranged on the support table for clamping and positioning the aluminum alloy profile, a base is arranged at the bottom of the support table, a pushing mechanism and a turning mechanism are arranged inside the base for pushing the support table to slide on the base and rotate and turn around during the sliding, and a vertical shaft is also fixedly installed at the bottom of the support table; The positioning assembly includes two positioning clamps, and the two positioning clamps can slide relative to the support table to move closer to or farther from each other; The pushing mechanism includes a moving seat and a cylinder. The moving seat is slidably arranged in the base, and the moving seat is arranged at the telescopic end of the cylinder, and can slide under the drive of the cylinder, and the vertical axis is rotatably assembled in the moving seat; The flip mechanism includes a gear, a toggle and a one-way bearing. The gear is arranged at the bottom end of the vertical shaft. The toggle is arranged in the base and can push the gear to rotate when it is away from the body. The one-way bearing is arranged between the vertical shaft and the moving seat.

[0007] The effect is that the aluminum alloy profile is positioned on the support table from the middle part by the positioning component, and after the end of the aluminum alloy profile is processed, the pushing mechanism can separate the end of the aluminum alloy profile from the machine body, and with the cooperation of the flipping mechanism, the aluminum alloy profile can be turned around and the unprocessed end can be sent into the interior of the machine body. There is no need to disassemble the aluminum alloy profile, and the automatic turning can be completed quickly, which saves the trouble of workers repeatedly disassembling and assembling the aluminum alloy profile, and improves the end milling efficiency of the aluminum alloy profile.

[0008] Preferably, a mounting groove is provided inside the support platform along its length direction, a sliding groove is provided inside the base along its length direction, and the movable seat is slidably assembled in the sliding groove.

[0009] Preferably, the positioning assembly also includes a double-headed screw and a slider. The double-headed screw is rotatably assembled inside the mounting groove, and the threads at both ends of the double-headed screw have opposite rotation directions. The slider is slidably connected in the mounting groove. There are two sliders, which are respectively threaded at both ends of the double-headed screw. Two positioning clamps are respectively fixed on the two sliders. The effect is that by rotating the double-headed screw, the mounting grooves of the two positioning clamps are pushed to slide in opposite directions and approach each other, so that the aluminum alloy profile can be clamped and positioned to the top of the support platform to facilitate end milling of the aluminum alloy profile.

[0010] Preferably, a limiting groove is provided at the bottom of the slide groove, the gear is located inside the limiting groove, a flip part is provided at one end of the limiting groove away from the body, and the width of the flip part is greater than the width of the limiting groove, and the toggle member is provided in the flip part.

[0011] Preferably, the flipping mechanism also includes a limit block, which is slidably assembled in the slide groove and fixedly installed at the bottom end of the vertical shaft. The gear is fixedly installed at the bottom of the limit block and is coaxially arranged with the vertical shaft. The effect is that the limit block slides in the limit groove to limit the vertical shaft from rotating. When the limit block enters the flipping part, as the width increases, the limit block loses the limit of the limit groove, allowing the vertical shaft and the gear to rotate, so that the gear can rotate after entering the flipping part.

[0012] Preferably, the toggle member includes a support, an inclined plate and a spring. The support has a plurality of equidistantly fixed members in the flipping portion. The inclined plate is rotatably assembled in the support. One end of the inclined plate away from the support extends into a limiting groove. The spring is arranged between the inclined plate and the base. The effect of the spring is that the inclined plate is supported by the spring to maintain an inclined state. When the support platform is away from the machine body, the gear can be pushed to rotate. When the support platform is close to the machine body, the inclined plate can compress the spring to avoid blocking the gear.

[0013] Preferably, a feed port is provided on the machine body, a slide rail fixed on the machine body is provided directly below the feed port, the base is slidably assembled on the slide rail, and an adjustment mechanism is provided between the slide rail and the base for adjusting the distance between the base and the machine body.

The effect is that by rotating the lead screw to push the threaded barrel to move, the distance between the base and the machine body can be adjusted, and then the distance between the initial position of the support platform and the machine body can be adjusted to facilitate the processing of aluminum alloy profiles of different lengths.

[0015] Beneficial effects: When the present invention is in use, the aluminum alloy profile is positioned on the support table from the middle part by the positioning component. After the end of the aluminum alloy profile is processed, the pushing mechanism can separate the end of the aluminum alloy profile from the machine body, and with the cooperation of the flipping mechanism, the aluminum alloy profile can be turned around and the unprocessed end can be sent into the interior of the machine body. There is no need to disassemble the aluminum alloy profile, and the automatic turning can be completed quickly, which saves the trouble of workers repeatedly disassembling and assembling the aluminum alloy profile, thereby improving the end milling efficiency of the aluminum alloy profile.

The support table 20 is arranged on the body 10, and is used for supporting the aluminum alloy profile. The positioning assembly 30 is located on the support table 20, and can clamp and position the aluminum alloy profile. The pushing mechanism 40 is arranged on one side of the support table 20, and can push the support table 20 away from or close to the body 10, and the flipping mechanism 50 drives the support table 20 to rotate when it moves, so that the aluminum alloy profile turns around. The adjusting mechanism 60 is located below the support table 20, and can adjust the distance between the initial position of the support table 20 and the body 10.

[0026] refer to Figure 1 A feed port 12 is provided on the machine body 10 to facilitate the end of the aluminum alloy profile to enter the interior of the machine body 10 . A slide rail 13 fixed on the machine body 10 is provided directly below the feed port 12 , and a support platform 20 is provided on the slide rail 13 .

[0027] refer to Figure 2 , Figure 3 , Figure 4 as well as Figure 6 A mounting groove 21 is provided inside the support platform 20 along its length direction, and the positioning assembly 30 is arranged in the mounting groove 21. A base 22 is provided at the bottom of the support platform 20, and the base 22 is slidably assembled inside the slide rail 13. The adjustment mechanism 60 is arranged between the base 22 and the slide rail 13. A slide groove 23 is provided inside the base 22 along its length direction to facilitate the installation of the pushing mechanism 40. A limiting groove 24 is provided at the bottom of the slide groove 23, and a flip part 25 is provided at one end of the limiting groove 24 away from the body 10, and the width of the flip part 25 is greater than the width of the limiting groove 24 to facilitate the installation of the flip mechanism 50.

[0028] refer to Figure 4 The positioning assembly 30 includes a double-headed screw 31, a slider 32 and a positioning clamping plate 33. The double-headed screw 31 is rotatably assembled in the mounting groove 21, and the threads at both ends of the double-headed screw 31 have opposite rotation directions. The slider 32 is slidably connected in the mounting groove 21. There are two sliders 32 and they are respectively threadedly connected to the two ends of the double-headed screw 31. There are two positioning clamping plates 33 that are respectively fixed on the two sliders 32, and the two positioning clamping plates 33 are symmetrically arranged. By rotating the double-headed screw 31, it pushes the two sliders 32 to slide in opposite directions and approach each other, so that the aluminum alloy profile on the support platform 20 can be clamped and positioned, so as to facilitate end milling of the aluminum alloy profile. In order to facilitate the rotation of the double-headed screw 31, a motor 34 is arranged at the end of the double-headed screw 31.

[0029] refer to Figure 6 The pushing mechanism 40 includes a moving seat 41 and a cylinder 42. The moving seat 41 is slidably assembled inside the slide groove 23. The cylinder 42 is fixedly installed at one end of the slide groove 23 close to the body 10, and the telescopic end of the cylinder 42 is fixedly connected to the moving seat 41. By telescoping the cylinder 42, the moving seat 41 is pushed to slide in the slide groove 23, which can drive the support table 20 away from or close to the body 10, and then make the end of the aluminum alloy profile detach from or enter the feed port 12. A vertical shaft 26 is fixedly installed at the bottom of the support table 20, and the vertical shaft 26 is rotatably assembled in the moving seat 41.

[0030] refer to Figure 3 , Figure 4 as well as Figure 7The flip mechanism 50 includes a limit block 51, a gear 52, a toggle member 53 and a one-way bearing 54. The limit block 51 is slidably arranged in the limit groove 24, and the limit block 51 is fixed to the bottom end of the vertical shaft 26. The gear 52 is fixedly installed at the bottom of the limit block 51, and the gear 52 is coaxially arranged with the vertical shaft 26. The toggle member 53 is arranged in the flip part 25. After the limit block 51 moves into the flip part 25 and loses the limit, the toggle member 53 pushes the gear 52 to rotate, so that the limit block 51 and the support platform 20 rotate 180°, realizes the U-turn of the two ends of the aluminum alloy profile, and then facilitates the processing of the two ends of the aluminum alloy profile. The one-way bearing 54 is arranged between the vertical shaft 26 and the moving seat 41, so that the vertical shaft 26 can only rotate in one direction, and then the gear 52 can rotate under the push of the toggle member 53 when it is away from the body 10, and the gear 52 will not rotate when it is reset close to the body 10.

[0031] refer to Figure 3 and Figure 7 The toggle member 53 includes a support 531, an inclined plate 532 and a spring 533. The support 531 has a plurality of equidistant fixed in the flip portion 25. The inclined plate 532 is rotatably assembled in the support 531. The end of the inclined plate 532 away from the support 531 extends into the limit groove 24. The spring 533 is arranged between the inclined plate 532 and the base 22 to keep the inclined plate 532 in an inclined state. When the gear 52 is away from the body 10, the inclined plate 532 can push the gear 52 to rotate. When the gear 52 approaches the body 10, the inclined plate 532 compresses the spring 533 to ensure that the inclined plate 532 does not affect the resetting of the gear 52.

[0032] refer to Figure 1 and Figure 2 The adjusting mechanism 60 includes a lead screw 61 and a threaded barrel 62. The lead screw 61 is rotatably assembled on the slide rail 13, and the threaded barrel 62 is fixedly mounted on the side wall of the base 22. The threaded barrel 62 is threadedly connected to the outside of the lead screw 61. By rotating the lead screw 61, the threaded barrel 62 is pushed to move the base 22, so that the distance between the base 22 and the body 10 can be adjusted, so as to adjust the distance between the initial position of the support platform 20 and the body 10, and then process the aluminum alloy profiles of different lengths. A hand wheel 611 is fixedly mounted on the end of the lead screw 61 to facilitate the rotation of the lead screw 61.

[0033] Working principle: The aluminum alloy profiles are placed side by side on the support platform 20, and the double-headed screw 31 is rotated to push the two sliders 32 to slide in opposite directions and approach each other, so that the two positioning clamps 33 clamp and position the aluminum alloy profiles from the middle part, and then the lead screw 61 is rotated to push the threaded cylinder 62 to move the base 22 and the support platform 20, so that the end of the aluminum alloy profile extends from the feed port 12 into the interior of the machine body 10, and the end mill 11 processes the aluminum alloy profile; When the end of the aluminum alloy profile is processed, the cylinder 42 pushes the movable seat 41 to slide in the slide groove 23, so that the support platform 20 is away from the body 10, and the end of the aluminum alloy profile is moved out of the body 10. As the support platform 20 continues to move, the limit block 51 enters the flip part 25 and loses the limit of the limit groove 24, so that the inclined plate 532 can push the moving gear 52 to rotate, and then drive the support platform 20 to rotate 180°, so that the two ends of the aluminum alloy profile turn around, and its unprocessed end faces the feed port 12, and then the movable seat 41 is driven by the cylinder 42 to reset. Under the restriction of the one-way bearing 54, the gear 52 cannot rotate, and then the inclined plate 532 is pressed to rotate during the reset to compress the spring 533, so that the unprocessed end of the aluminum alloy profile can extend into the feed port 12 for processing.

[0034] In the present invention, the aluminum alloy profile is positioned on the support table 20 from the middle part by the positioning component 30. After the end of the aluminum alloy profile is processed, the pushing mechanism 40 can separate the end of the aluminum alloy profile from the machine body 10, and with the cooperation of the flipping mechanism 50, the aluminum alloy profile is turned around and the unprocessed end is sent into the machine body 10. There is no need to disassemble the aluminum alloy profile, and the automatic turning can be completed quickly, which saves the trouble of repeated disassembly and assembly of the aluminum alloy profile by the staff, and improves the end milling efficiency of the aluminum alloy profile; the distance between the initial position of the support table 20 and the machine body 10 is adjusted by the adjustment mechanism 60, so that after the positioning component 30 positions the aluminum alloy profile from the middle part, the end of the aluminum alloy profile can be sent into the machine body 10, so as to facilitate the end milling of aluminum alloy profiles of different lengths.

[0035] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
