Description

Technical Field

[0001] This utility model relates to the field of milling cutter technology, specifically a milling cutter with a protective structure. Background Technology

[0002] A milling cutter is a rotary cutting tool used for milling operations. It has one or more cutting teeth and is used in machining to machine planes, steps, grooves, shaped surfaces, and cut off workpieces.

[0003] When not in use, operators typically cover the outer ring of the milling cutter with a protective sleeve to prevent external impacts and dust. However, after milling, metal shavings adhere to the cutter surface, forming a stubborn accumulation. In humid workshop environments or under the corrosive influence of coolant, these shavings are highly susceptible to oxidation or electrochemical corrosion of the cutter material, leading to rust and coating peeling. This severely weakens the cutting performance and fails to provide adequate protection for the cutter, making it unsuitable for operator use. Summary of the Invention

[0004] The purpose of this invention is to provide a milling cutter with a protective structure to solve the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a milling cutter with a protective structure, comprising a milling cutter body; a clamping mechanism is installed on the outer side of the top end of the milling cutter body, an adsorption mechanism is installed on the top end of the milling cutter body, a protective cylinder is installed on the outer side of the adsorption mechanism, a bottom ring is provided at the bottom end of the protective cylinder, a spring is installed inside the bottom ring, a baffle is installed at one end of the spring, the baffle moves inside the bottom ring, an angle is provided on the side of the baffle that is close to the top and bottom, and a scraper is installed on the side of the baffle that is close to the bottom.

[0006] Preferably, the inner wall of the protective cylinder above the scraper is provided with a limiting ring, and the inner wall of the limiting ring is provided with a protective layer.

[0007] Preferably, the clamping mechanism includes a fixing plate disposed on the outer side of the top of the milling cutter body, a connecting spring is installed at one end of the fixing plate, and a clamping plate is installed at the end of the connecting spring away from the fixing plate.

[0008] Preferably, the adsorption mechanism includes a magnetic suction plate disposed at the top of the clamping plate, and connecting rods are provided on both sides of the magnetic suction plate inside the protective cylinder. A collar is installed at the end of the connecting rod away from the magnetic suction plate, and the collar moves to the outer ring of the protective cylinder.

[0009] Preferably, connecting seats are installed on both sides of the top of the protective cylinder, and spring rods are installed inside the connecting seats.

[0010] Preferably, one end of the spring rod is located inside the collar, and the collar has a fixing groove inside, through which the spring rod is connected.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model utilizes a bottom ring, spring, baffle, scraper, and bevel joint in combination. As the milling cutter moves upward, it presses against the baffle along the bevel. The baffle moves, compressing the spring. One end of the baffle moves along the inside of the bottom ring, while the scraper on the baffle makes close contact with the outer surface of the milling cutter. As the milling cutter moves, the scraper effectively removes residual chips and oil adhering to the surface of the milling cutter, ensuring the milling cutter is clean and ready for the next use. When the milling cutter has completely moved into the protective cylinder, the spring releases its compression energy, pushing the baffle to reset. The reset baffle covers the bottom of the protective cylinder, protecting the bottom of the milling cutter and thus facilitating its use.

[0013] 2. This utility model uses a protective cylinder, a limiting ring, and a protective layer in combination. The limiting ring restricts the internal movement space of the protective cylinder and limits the bottom end of the milling cutter. The protective layer can absorb impact energy when the parts collide, reducing the impact force generated when the milling cutter collides, thus providing auxiliary protection for the milling cutter.

[0020] 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.

[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;

[0022] Example:

[0023] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the accompanying drawings. Figures 1 to 5 Please refer to the end mill with a protective structure provided in this application. Figure 1 , Figure 2 and Figure 5 The device includes a milling cutter body 1; a clamping mechanism 2 is installed on the outer side of the top of the milling cutter body 1; an adsorption mechanism 3 is installed on the top of the milling cutter body 1; a protective cylinder 5 is installed on the outer side of the adsorption mechanism 3; a bottom ring 6 is provided at the bottom end of the protective cylinder 5; a spring 601 is installed inside the bottom ring 6; a baffle 602 is installed at one end of the spring 601; the baffle 602 moves inside the bottom ring 6; an angled angle 604 is provided on the side of the baffle 602 that is close to the top and bottom; and a scraper 603 is installed on the side of the baffle 602 that is close to the bottom.

[0024] Specifically, by inserting the tip of the milling cutter into the clamping mechanism 2, the milling cutter will press the baffle 602 along the angle 604. The baffle 602 moves, causing the spring 601 to compress. One end of the baffle 602 moves along the inside of the bottom ring 6. At this time, the clamping mechanism 2 clamps the milling cutter, and the suction mechanism 3 provides auxiliary fixation for the milling cutter. Then, by moving the suction mechanism 3, the milling cutter is moved into the protective cylinder 5, so that the protective cylinder 5 protects the milling cutter. During the process of the milling cutter moving into the protective cylinder 5, the scraper 603 on the baffle 602 will make close contact with the outer surface of the milling cutter. As the milling cutter moves, the scraper 603 can effectively remove residual chips and oil stains attached to the surface of the milling cutter, ensuring that the milling cutter is clean and ready for the next use. When the milling cutter has completely moved into the protective cylinder 5, the spring 601 will push the baffle 602 to reset during the release of compression energy. The reset baffle 602 will cover the bottom of the protective cylinder 5, protecting the bottom end of the milling cutter.

[0025] Please refer to this carefully. Figure 1 and Figure 4 The inner wall of the protective cylinder 5 above the scraper 603 is provided with a limiting ring 501, and the inner wall of the limiting ring 501 is provided with a protective layer 502.

[0026] Specifically, in order to provide auxiliary protection for the milling cutter, the internal movement space of the protective cylinder 5 is clearly defined by the limiting ring 501, and the protective layer 502 is made of elastic rubber, which can absorb impact energy when the parts collide and reduce the impact force generated when the milling cutter collides, thus providing auxiliary protection for the milling cutter.

[0027] Please refer to this carefully. Figure 1 and Figure 2 The clamping mechanism 2 includes a fixing plate 203 disposed on the outer side of the top of the milling cutter body 1. A connecting spring 202 is installed at one end of the fixing plate 203, and a clamping plate 201 is installed at the end of the connecting spring 202 away from the fixing plate 203.

[0028] Specifically, in order to fix the milling cutter, when the milling cutter needs to be clamped, the milling cutter is moved upward, the milling cutter presses against the clamping plate 201, and the connecting spring 202 is compressed. The extrusion force generated by the connecting spring 202 can fix the milling cutter inside the two sets of clamping plates 201, thereby fixing the milling cutter. In addition, the elasticity of the connecting spring 202 can also adapt to milling cutters of different sizes, and provide appropriate clamping force through its own deformation, which increases the versatility and adaptability of the clamping mechanism 2.

[0029] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The adsorption mechanism 3 includes a magnetic suction plate 301 set at the top of the clamping plate 201. Connecting rods 302 are provided on both sides of the magnetic suction plate 301 inside the protective cylinder 5. A collar 303 is installed at the end of the connecting rod 302 away from the magnetic suction plate 301. The collar 303 moves to the outer ring of the protective cylinder 5.

[0030] Specifically, in order to assist in fixing the milling cutter, the adsorption mechanism 3 uses a magnetic suction plate 301 as its core and is connected to a collar 303 via a connecting rod 302. The magnetic suction plate 301 is located at the top of the clamping plate 201, the collar 303 is located on the outer ring of the protective cylinder 5, and the connecting rod 302 connects the two and moves inside the protective cylinder 5. The magnetic suction plate 301 can assist in fixing the milling cutter with a magnetic top. When the personnel move to store the milling cutter inside the protective cylinder 5, the connecting rod 302 will move along the groove inside the protective cylinder 5, which can keep it moving horizontally.

[0031] Please refer to this carefully. Figure 1 and Figure 3 Connecting seats 4 are installed on both sides of the top of the protective cylinder 5, and spring rods 401 are installed inside the connecting seats 4.

[0032] Please refer to this carefully. Figure 1 and Figure 3One end of the spring rod 401 is located inside the collar 303. The collar 303 has a fixing groove 7 inside, and the spring rod 401 is connected inside the fixing groove 7.

[0033] Specifically, in order to fix the position of the magnetic plate 301, the connecting seat 4 is used to fix the connecting spring rod 401. When the magnetic plate 301 drives the collar 303 to move to the fixed position, the collar 303 will squeeze one end of the spring rod 401. As the collar 303 moves to the designated position, the spring rod 401 is not squeezed, and one end of the spring rod 401 will be embedded in the fixing groove 7 of the collar 303. Then the position of the magnetic plate 301 can be fixed, so that the milling cutter can be stored inside the protective cylinder 5 for protection.

[0034] Working principle: By moving the milling cutter upwards, the cutter presses against the baffle 602 along the angle 604. The baffle 602 moves, compressing the spring 601. One end of the baffle 602 moves along the inside of the bottom ring 6. Simultaneously, the scraper 603 on the baffle 602 makes close contact with the outer surface of the milling cutter. As the milling cutter moves, the scraper 603 effectively removes residual chips and oil adhering to the surface of the milling cutter. Then, the top of the milling cutter presses against the clamping plate 201, compressing the connecting spring 202. The compressive force generated by the connecting spring 202 can fix the milling cutter inside the two sets of clamping plates 201. At the same time, the magnetic suction plate 3... 01 can assist in fixing the magnetic end mill at the top. When the personnel move to store the end mill inside the protective cylinder 5, the connecting rod 302 will move along the groove inside the protective cylinder 5. When the magnetic suction plate 301 drives the collar 303 to a fixed position, the collar 303 will squeeze one end of the spring rod 401. As the collar 303 moves to the designated position, the spring rod 401 is not squeezed, and one end of the spring rod 401 will be embedded in the fixing groove 7 of the collar 303. The position of the magnetic suction plate 301 can be fixed, and the end mill can be stored inside the protective cylinder 5 for protection.

[0035] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
