Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, and in particular to a precision milling cutter that is easy to process and use. Background Technology

[0002] A milling cutter is a rotating cutting tool with one or more cutting teeth used for milling operations. During operation, each cutting tooth intermittently removes the excess material from the workpiece. Cylindrical milling cutters are used to machine planes on horizontal milling machines. The cutting teeth are distributed on the circumference of the milling cutter. According to the tooth shape, they are divided into straight teeth and helical teeth. According to the number of teeth, they are divided into coarse teeth and fine teeth. Helical coarse tooth milling cutters have fewer teeth, higher tooth strength, and larger chip space, making them suitable for roughing. Fine tooth milling cutters are suitable for finishing.

[0003] Currently, milling cutters often break when cutting into or removing workpieces. A better solution is to adjust the cutter's extension length to ensure it extends to the necessary distance. However, adjusting the extension length using existing technology is inconvenient, resulting in poor anti-breakage performance, easy breakage, and an inability to observe the actual extension length of the cutter, which presents certain shortcomings. Utility Model Content

[0004] The purpose of this invention is to solve the problems of inconvenience in adjusting the extension length of the milling cutter and the inability to observe the actual extension length of the cutter in the existing technology, and to propose a precision milling cutter that is easy to process and use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision milling cutter for easy machining includes a mounting cylinder and a milling cutter body. A cover plate is provided above the mounting cylinder, and a set of first bolts is provided on the outside of the cover plate. The mounting cylinder and the cover plate are connected by the set of first bolts. An electric push rod is mounted on the bottom surface of the cover plate, and a buffer mechanism is provided below the electric push rod. The buffer mechanism includes a buffer cylinder, the inner wall of which is slidably connected to the output shaft of the electric push rod. A connecting plate one is fixedly connected to the bottom surface of the buffer cylinder. The outer surface of the milling cutter body is slidably connected to the mounting cylinder. A connecting plate two is fixedly connected to the top of the milling cutter body. Two second bolts are provided inside the connecting plate one, and the connecting plate one and the connecting plate two are connected by the second bolts. An outer connecting ring is fixedly connected to the outer surface of the mounting cylinder, and a limit mechanism is provided outside the outer connecting ring. A connecting shaft is fixedly connected to the upper surface of the cover plate.

[0007] Preferably, a damper is slidably connected to the inner wall of the buffer cylinder, and the top end of the damper is fixedly connected to the output shaft of the electric push rod.

[0008] Preferably, a buffer spring is fixedly connected to the bottom surface of the damper, and the bottom end of the buffer spring is fixedly connected to the inner bottom wall of the buffer cylinder.

[0009] Preferably, the limiting mechanism includes a positioning rod, which is fixedly connected to an outer connecting ring. A rotatable plate is rotatably connected to the outer surface of the positioning rod, and scale lines are engraved on the outer surface of the rotatable plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 A precision milling cutter that is easy to process and use includes a mounting cylinder 1 and a milling cutter body 7. A cover plate 3 is provided on the top of the mounting cylinder 1, and a set of first bolts 4 are provided on the outside of the cover plate 3. The mounting cylinder 1 and the cover plate 3 are connected by the set of first bolts 4. An electric push rod 5 is installed on the bottom surface of the cover plate 3. By using the cooperation of the cover plate 3 and the first bolts 4, the top of the mounting cylinder 1 can be opened, so that the milling cutter body 7 can be inserted into the mounting cylinder 1 for installation.

[0023] A buffer mechanism 6 is provided below the electric push rod 5. The buffer mechanism 6 includes a buffer cylinder 601. The top of the buffer cylinder 601 has an opening that matches the output shaft of the electric push rod 5. The inner wall of the buffer cylinder 601 is slidably connected to the output shaft of the electric push rod 5.

[0024] A connecting plate 8 is fixedly connected to the bottom surface of the buffer cylinder 601. A damper 602 is slidably connected to the inner wall of the buffer cylinder 601. The top end of the damper 602 is fixedly connected to the output shaft of the electric push rod 5. A buffer spring 603 is fixedly connected to the bottom surface of the damper 602. The bottom end of the buffer spring 603 is fixedly connected to the inner bottom wall of the buffer cylinder 601. By using the cooperation of the damper 602 and the buffer spring 603, the vibration can be buffered when the milling cutter body 7 experiences up-and-down vibration during milling, thereby providing a certain degree of protection for the milling cutter body 7.

[0025] The outer surface of the milling cutter body 7 is slidably connected to the mounting cylinder 1. A connecting plate 2 9 is fixedly connected to the top of the milling cutter body 7. Two second bolts 10 are provided inside the connecting plate 1 8. The connecting plate 1 8 and the connecting plate 2 9 are connected by the second bolts 10. The connecting plate 1 8 and the connecting plate 2 9 play a guiding role inside the mounting cylinder 1, so that when the connecting shaft 2 drives the cover plate 3 and the mounting cylinder 1 to rotate, it can accurately drive the milling cutter body 7 to rotate. Furthermore, the setting of the connecting plate 1 8 and the connecting plate 2 9 can play a guiding role when installing the milling cutter body 7.

[0026] A connecting shaft 2 is fixedly connected to the upper surface of the cover plate 3. The connecting shaft 2 is the drive shaft of a commonly used milling cutter.

[0027] An outer connecting ring 11 is fixedly connected to the outer surface of the mounting cylinder 1. A limiting mechanism 13 is provided on the outside of the outer connecting ring 11. The limiting mechanism 13 includes a positioning rod 1301, which is fixedly connected to the outer connecting ring 11. A rotatable plate 1302 is rotatably connected to the outer surface of the positioning rod 1301. A scale line 1306 is engraved on the outer surface of the rotatable plate 1302. By observing the scale line 1306, the extension length of the milling cutter body 7 can be determined.

[0028] A rod 1303 is slidably connected to the inner wall of the rotatable plate 1302. A pull plate 1304 is fixedly connected to the right end of the rod 1303. An external opening 12 is provided on the outer surface of the mounting cylinder 1. The outer surface of the rod 1303 contacts the external opening 12. By inserting the rod 1303 into the external opening 12, the position of the rotatable plate 1302 can be limited to avoid affecting the milling work of the milling cutter body 7.

[0029] A connecting spring 1305 is sleeved on the outer surface of the insertion rod 1303. The two ends of the connecting spring 1305 are fixedly connected to the rotatable plate 1302 and the pull plate 1304, respectively. The connecting spring 1305... Figure 4 In its natural state, the connecting spring 1305 keeps the insert rod 1303 inserted into the outer opening 12, preventing the milling cutter body 7 from sliding out of the outer opening 12 during milling operations.

[0030] Working principle: When the extension length of the milling cutter body 7 needs to be adjusted according to the milling requirements of the workpiece, pulling the pull plate 1304 can pull the insert rod 1303 out from the inside of the external opening 12. Rotating the rotatable plate 1302 to the vertical position and starting the electric push rod 5 can drive the buffer mechanism 6, the connecting plate 1 8 and the connecting plate 2 9 to move, thereby adjusting the extension of the milling cutter body 7 to a suitable length and avoiding excessive extension that could cause the milling cutter body 7 to break easily.
