Description

Technical Field

[0001] This utility model relates to a vertical milling cutter, specifically a vertical milling cutter with a deburring component, belonging to the technical field of vertical milling cutters. Background Technology

[0002] End mills are the most commonly used milling cutters on CNC machine tools. End mills have cutting tools on both the cylindrical surface and the end face, which can perform cutting simultaneously or individually. They are mainly used for plane milling, groove milling, step milling, and profile milling, and have become an indispensable, efficient, and multi-functional tool in modern industrial processing.

[0003] In existing technologies, such as the end mill disclosed in CN209998438U, a shank and a cutter head are included. The shank includes a body and a transition portion formed at one end. A blind hole is formed on the end face of the transition portion away from the body along the axial direction of the shank. The cutter head is ground from a cemented carbide cylindrical bar and has a cutting portion with a cutting edge in its circumferential direction. The cutter head is inserted into the blind hole and fixedly connected to the transition portion through its mating area. Through this structural design, the rigidity and wear resistance of the cutting portion are improved because the cutter head is ground from a cemented carbide cylindrical bar. Furthermore, since the cutting edge is integrally machined with the cutter head, compared to the design in existing technologies where the cutting edge is welded to the cutter body, the welding point of the end mill provided by this invention is at the connection between the mating area of ​​the cutter head and the blind hole of the transition portion. Because the mating area at this point is more sufficient, the welding strength is higher, the cutter is less prone to breakage, and its service life is effectively improved.

[0004] However, in implementing the relevant technology, the following problems were found with the end mill designed above: Although the welding strength of the end mill can be improved by the cooperation of components such as the cutting edge in the prior art, in actual use, burrs are required after machining. The end mill needs to be disassembled and replaced with a deburring end mill for re-grinding, which results in slow machining efficiency. In view of this, an end mill with a deburring component is provided to overcome the above defects. Utility Model Content

[0005] This invention addresses the problem of slow processing efficiency caused by the need to disassemble and replace the end mill with a deburring end mill after machining to remove burrs, which results in slow processing efficiency.

[0006] The present invention achieves the above objectives through the following technical solution: a vertical milling cutter with a deburring component, comprising a clamping rod, a connecting rod fixed to the bottom end of the clamping rod, and a sliding groove provided on the outer wall of the connecting rod, and an adjustment mechanism provided outside the sliding groove;

[0007] The adjustment mechanism includes a limiting frame, which is rotatably connected to the outside of the connecting rod. The inner wall of the limiting frame has a limiting groove, and a collar is placed inside the limiting groove. A connecting hole is opened on the inner wall of the collar corresponding to the position of the connecting rod. A connecting block is fixed on the inner wall of the collar corresponding to the position of the sliding groove. A cutter bar is fixed at one end of the connecting block that passes through the connecting rod. A deburring milling cutter is fixed at the bottom end of the cutter bar, and a conventional milling cutter is connected below the deburring milling cutter.

[0008] As a further improvement of this utility model: the limiting frame is threadedly connected to the connecting rod, and the limiting frame and the collar form a rotating structure.

[0009] As a further improvement of this utility model: the collar and the connecting rod form a sliding structure, and the collar and the connecting rod are tightly fitted together.

[0010] As a further improvement of this utility model: the connecting rod forms a sliding structure with the connecting block through the sliding groove, and the connecting rod and the tool bar also form a sliding structure.

[0011] As a further embodiment of this utility model: a cleaning mechanism is provided below the connecting rod. The cleaning mechanism includes a sleeve, which is located below the connecting rod. A connecting ring is fixed to one end of the sleeve that passes through the connecting rod. A through hole is provided inside the connecting ring.

[0012] As a further improvement of this utility model, the cleaning mechanism also includes a mounting block, which is fixed inside the through hole and has a brush embedded in its outer wall.

[0013] As a further improvement of this utility model: the connecting rod is threadedly connected to the connecting ring, and the connecting rod is tightly fitted to the sleeve.

[0014] The beneficial effects of this utility model are: after the conventional milling cutter part is finished, the limiting frame is rotated to drive the collar through the limiting groove, so that the connecting block slides stably along the slide groove, thereby allowing the cutter bar to drive the deburring milling cutter part to pass through the connecting rod, so that it can continue to drill for deburring work, avoiding the troublesome need to disassemble and replace multiple times during deburring.

[0015] After machining is completed, the sleeve is rotated by the connecting ring, and manually rotated outside the deburring cutter section and the regular milling cutter section to allow the brush embedded in the mounting block inside the through hole to scrape off the dust and debris.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0022] like Figures 1 to 4 As shown, a vertical milling cutter with a deburring assembly includes a clamping rod 1, a connecting rod 2 fixed to the bottom end of the clamping rod 1, a groove 3 formed on the outer wall of the connecting rod 2, and an adjustment mechanism 4 provided outside the groove 3; the adjustment mechanism 4 includes a limiting frame 401, which is rotatably connected to the outside of the connecting rod 2, a limiting groove 402 formed on the inner wall of the limiting frame 401, a collar 403 disposed inside the limiting groove 402, a connecting hole 404 formed on the inner wall of the collar 403 corresponding to the position of the connecting rod 2, a connecting block 405 fixed on the inner wall of the collar 403 corresponding to the position of the groove 3, a cutter shank 406 fixed to one end of the connecting block 405 that passes through the connecting rod 2, a deburring milling cutter part 407 fixed to the bottom end of the cutter shank 406, and the lower end of the deburring milling cutter part 407... The device is connected to a conventional milling cutter 408. A limiting frame 401 is threadedly connected to a connecting rod 2. The limiting frame 401 and the collar 403 form a rotating structure, and the collar 403 and the connecting rod 2 form a sliding structure. The collar 403 and the connecting rod 2 are tightly fitted together. The connecting rod 2 forms a sliding structure with the connecting block 405 through the sliding groove 3. The connecting rod 2 and the tool holder 406 also form a sliding structure. After the conventional milling cutter 408 has finished processing, the limiting frame 401 is rotated to drive the collar 403 through the limiting groove 402, causing the connecting block 405 to slide stably along the sliding groove 3. This allows the tool holder 406 to drive the deburring milling cutter 407 through the connecting rod 2, so that it can continue drilling for deburring work, avoiding the troublesome need for multiple disassembly and replacement during deburring. Example 2

[0023] In addition to all the technical features in Embodiment 1, this embodiment also includes: a cleaning mechanism 5 is provided below the connecting rod 2. The cleaning mechanism 5 includes a sleeve 501, which is located below the connecting rod 2. A connecting ring 502 is fixed to one end of the sleeve 501 that passes through the connecting rod 2. A through hole 503 is provided inside the connecting ring 502. The cleaning mechanism 5 also includes a mounting block 504, which is fixed inside the through hole 503. A brush 505 is embedded in the outer wall of the mounting block 504. The connecting rod 2 is threadedly connected to the connecting ring 502, and the connecting rod 2 is tightly fitted to the sleeve 501. After processing, the sleeve 501 is rotated by the connecting ring 502, and manually rotated outside the deburring milling cutter part 407 and the conventional milling cutter part 408, so that the brush 505 embedded in the mounting block 504 inside the through hole 503 scrapes away the adsorbed dust and debris.

[0024] Working principle: The clamping rod 1 is used to connect to the power end of the machine tool. By rotating the limiting frame 401, it slides along the connecting rod 2, allowing the collar 403 to slide along the connecting rod 2 through the connecting hole 404 via the limiting groove 402. This causes the connecting block 405 to slide stably along the sliding groove 3, allowing the tool holder 406 to slide along the connecting rod 2. This allows the deburring milling cutter 407 to pass through the connecting rod 2, enabling deburring work to be performed after the conventional milling cutter 408 has been processed. The limiting frame 401 facilitates the adjustment of length and position, improving versatility and applicability. The sleeve 501 is threadedly connected to the connecting rod 2 via the connecting ring 502, facilitating disassembly and assembly. During disassembly and assembly, the brush 505, which is embedded in the mounting block 504 inside the through hole 503, abuts against the deburring milling cutter 407, thus easily scraping away the adsorbed dust and debris.
