Description

Technical Field

[0001] This utility model relates to the field of milling cutter devices, and in particular to an anti-slip milling cutter assembly. Background Technology

[0002] A milling cutter is a rotary cutting tool specifically designed for mounting on a milling machine. Milling cutters play a vital role in metalworking, woodworking, and many other material processing fields. It consists of two main parts: the shank and the cutter body. The shank connects to the rotating structure of the milling machine, providing power for the cutter's operation. The cutter body is typically designed with sharp cutting edges and helical grooves. These cutting edges enable precise machining and cutting of various materials during the cutter's rotation. Simultaneously, the helical grooves guide away debris generated during cutting, preventing debris accumulation from affecting machining quality and tool life.

[0003] Currently, the fixation of end mills on milling machines typically relies on the combined use of an elastic anti-slip sleeve and a tool holder. The anti-slip sleeve is fitted onto the tool holder, while the tool holder clamps the end mill by holding the anti-slip sleeve. End mills are usually made of tungsten carbide and are typically coated with anti-rust oil at the factory. Although cleaning is often performed before installation, manual cleaning may leave some anti-rust oil residue. This residue often forms an oil film on the inner wall of the protective sleeve, which, combined with the smooth tungsten carbide surface, may reduce the anti-slip effect of the anti-slip sleeve and thus affect the stability of the end mill. In addition, the anti-slip sleeve and the tool holder are often fixed only by clamping, which is often not very stable. Since end mills often need to rotate at high speeds during operation, they may vibrate or slip, which may not only adversely affect the quality of the workpiece but also pose certain safety hazards.

[0004] Therefore, those skilled in the art have provided an anti-slip end mill assembly to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-slip milling cutter assembly that can ensure both anti-slip effect and clamping stability.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An anti-slip milling cutter assembly includes a main body mechanism and a clamping mechanism, wherein a connecting mechanism is provided inside the clamping mechanism, and an anti-slip mechanism is provided inside the connecting mechanism;

[0008] The main body includes a knife handle, the connecting mechanism includes a connecting sleeve, the outer surface of the connecting sleeve has two slots near the upper end, the outer surface of the connecting sleeve has two sliding grooves near the lower end, the outer surface of the connecting sleeve has four limiting grooves, and the inner surface of the connecting sleeve has an oil-absorbing layer fixedly sleeved near the lower end.

[0009] The anti-slip mechanism includes a fixed ring, an outer sleeve, and an inner sleeve. A rubber sleeve is fixedly installed at the upper end of the fixed ring, and a sliding ring is fixedly installed at the lower end of the inner sleeve. Two connecting rods are fixedly installed at the upper end of the sliding ring near the edge, and sliding rods are fixedly installed on the side surface of the sliding ring near the two connecting rods.

[0010] The clamping mechanism includes a tool clamp top, a threaded post fixedly provided at the lower end of the tool clamp top, a threaded ring threaded on the outer surface of the threaded post, two telescopic posts slidably provided on the side surface of the threaded post, and two spring pieces fixedly provided inside the threaded post.

[0011] Furthermore, the lower end of the handle is provided with a blade body, and the handle is sleeved inside a rubber sleeve.

[0012] Furthermore, the four limiting grooves are respectively connected to the two ends of the two sliding grooves, the two locking grooves are respectively engaged with the two telescopic columns, and the connecting sleeve is fitted inside the threaded column.

[0013] Furthermore, the outer sleeve is slidably fitted inside the connecting sleeve near the upper end, and the outer sleeve is fitted over the rubber sleeve.

[0014] Furthermore, the inner sleeve is slidably fitted inside the connecting sleeve near the lower end, and the portion of the inner sleeve near the upper end is fitted inside the rubber sleeve.

[0015] Furthermore, the fixing ring is fixedly sleeved on the inner surface of the threaded column, the inner surface of the rubber sleeve is provided with an anti-slip layer, and the sliding ring is slidably sleeved on the inner surface of the connecting sleeve.

[0016] Furthermore, the upper ends of both connecting rods are fixedly connected to the lower end of the outer sleeve, and the two sliding rods are respectively slidably sleeved in the two sliding grooves.

[0017] Furthermore, the lower ends of both spring pieces are fixedly disposed inside the threaded post, and the upper ends of the two spring pieces are respectively fixedly connected to the two telescopic posts.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model proposes an anti-slip milling cutter assembly, which includes a connecting mechanism and a clamping mechanism. During use, by rotating the threaded ring, it can slide up and down along the threaded post. The threaded ring can apply pressure to the telescopic post, and the change in the position of the threaded ring can drive the telescopic post to extend and retract, so that the telescopic post engages with the slot. The spring piece can ensure the telescopic post returns to its original position for repeated loading and unloading. The close cooperation between the telescopic post and the slot completes the stable clamping and fixing of the milling cutter. This clamping method is simple to operate and can enhance the stability of clamping, effectively reducing vibration and slippage during the rotation of the milling cutter, thereby ensuring the machining quality of the workpiece and improving the safety of the milling cutter operation.

[0020] 2. This utility model proposes an anti-slip end mill assembly, which includes a connecting mechanism and an anti-slip mechanism. During use, the main anti-slip structure is a rubber sleeve. The inner sleeve moves upward to expand the rubber sleeve, facilitating the insertion of the tool holder, while the outer sleeve moves downward to compress the rubber sleeve, increasing the pressure of the rubber sleeve on the tool holder and thus improving friction. At the same time, the oil-absorbing layer can clean the rust-preventive oil again. This ensures smooth insertion of the tool holder and enhances the anti-slip effect of the anti-slip mechanism on the tool holder, thereby ensuring the stability of the end mill assembly during operation.

[0028] 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.

[0029] Reference Figure 1 An embodiment of this utility model is provided: an anti-slip milling cutter assembly, including a main body mechanism 1 and a clamping mechanism 4, wherein a connecting mechanism 2 is provided inside the clamping mechanism 4, and an anti-slip mechanism 3 is provided inside the connecting mechanism 2;

[0030] Specifically, the main body mechanism 1 is the main part of the milling cutter, the clamping mechanism 4 is used for the machine tool to clamp and fix the milling cutter, and the anti-slip mechanism 3 is located between the milling cutter and the clamping mechanism 4. The friction is increased by the rubber sleeve 301, thereby achieving the anti-slip effect. The anti-slip mechanism 3 is divided into upper and lower parts, and the connecting mechanism 2 puts the two parts together.

[0031] Reference Figure 1 The main body 1 includes a handle 101, and a blade body 102 is provided at the lower end of the handle 101. The handle 101 is sleeved inside the rubber sleeve 301.

[0032] Specifically, the tool holder 101 is for fixing the milling cutter on the machine tool, and the cutter body 102 is a working structure for cutting and grinding. The cutter body 102 is provided with multiple cutting edges, and threaded grooves are provided next to the cutting edges to facilitate the discharge of cutting debris and avoid the impact of debris on the operation of the milling cutter.

[0033] Reference Figure 3 , Figure 4 The connecting mechanism 2 includes a connecting sleeve 201. Two slots 202 are formed on the outer surface of the connecting sleeve 201 near the upper end. Two sliding grooves 203 are formed on the outer surface of the connecting sleeve 201 near the lower end. Four limiting grooves 204 are formed on the outer surface of the connecting sleeve 201. An oil-absorbing layer 205 is fixedly fitted on the inner surface of the connecting sleeve 201 near the lower end. The four limiting grooves 204 are respectively connected to the two ends of the two sliding grooves 203. The two slots 202 are respectively engaged with the two telescopic columns 404. The connecting sleeve 201 is fitted inside the threaded column 403.

[0034] Specifically, the connecting mechanism 2 combines the two parts of the anti-slip mechanism 3. The connecting sleeve 201 can fix the rubber sleeve 301 and ensure the movement of the outer sleeve 303 and the inner sleeve 304. The slot 202 can engage with the telescopic column 404 to fix the milling cutter on the machine tool. The slide groove 203 can ensure the sliding of the slide rod 306. The limiting groove 204 is located at both ends of the slide groove 203. When the slide rod 306 slides to both ends of the slide groove, the limiting groove 204 can limit it to ensure the stability of the anti-slip mechanism 3, and thus ensure the stability of the milling cutter. The oil-absorbing layer 205 is located at the bottom of the inner surface of the connecting sleeve 201. The inner diameter of the oil-absorbing layer 205 is the same as the outer diameter of the tool holder 101. When the tool holder 101 enters the interior of the connecting sleeve 201, the oil-absorbing layer 205 can further clean the residual anti-rust oil on the outer surface of the tool holder 101.

[0035] Reference Figure 4 , Figure 5 The anti-slip mechanism 3 includes a fixed ring 302, an outer sleeve 303 and an inner sleeve 304. A rubber sleeve 301 is fixedly installed at the upper end of the fixed ring 302, and a sliding ring 305 is fixedly installed at the lower end of the inner sleeve 304. Two connecting rods 307 are fixedly installed at the upper end of the sliding ring 305 near the edge, and sliding rods 306 are fixedly installed on the side surface of the sliding ring 305 near the two connecting rods 307.

[0036] The outer sleeve 303 is slidably fitted inside the connecting sleeve 201 near the upper end, and the outer sleeve 303 is fitted outside the rubber sleeve 301. The inner sleeve 304 is slidably fitted inside the connecting sleeve 201 near the lower end, and the upper part of the inner sleeve 304 is fitted inside the rubber sleeve 301. The fixing ring 302 is fixedly fitted on the inner surface of the threaded post 403. The inner surface of the rubber sleeve 301 is provided with an anti-slip layer. The sliding ring 305 is slidably fitted on the inner surface of the connecting sleeve 201. The upper ends of the two connecting rods 307 are fixedly connected to the lower end of the outer sleeve 303. The two sliding rods 306 are respectively slidably fitted in the two sliding grooves 203.

[0037] Specifically, the rubber sleeve 301 is made of rubber and has a certain degree of elasticity. When subjected to external force, it can expand and contract. The retaining ring 302 is used for the fixed connection between the rubber sleeve 301 and the connecting sleeve 201, fixing the position of the rubber sleeve 301. The inner diameter of the outer sleeve 303 is the same as the outer diameter of the rubber sleeve 301 when it is contracted. The outer sleeve 303 can compress and contract the rubber sleeve 301 from the outside, enhancing the anti-slip effect. The outer diameter of the inner sleeve 304 is the same as the inner diameter of the rubber sleeve 301 when it is expanded. The inner sleeve 304 can stretch and expand the rubber sleeve 301 from the inside to ensure the smooth entry of the tool holder 101. The inner sleeve 304 has a thin wall width. The sliding ring 305 is fitted into the inner wall of the connecting sleeve 201 to ensure that the inner sleeve 304 slides up and down and rotates stably. Both the outer sleeve 303 and the inner sleeve 304 are made of smooth metal material. The slide rod 306 facilitates the movement of the outer sleeve 303 and the inner sleeve 304 from the outside. The connecting rod 307 is used to connect the outer sleeve 303 and the inner sleeve 304 to ensure that the two lift and rotate synchronously.

[0038] Reference Figure 2 The clamping mechanism 4 includes a tool clamp top 401, a threaded post 403 fixedly provided at the lower end of the tool clamp top 401, a threaded ring 402 threadedly sleeved on the outer surface of the threaded post 403, two telescopic posts 404 slidably sleeved on the side surface of the threaded post 403, and two spring pieces 405 fixedly provided inside the threaded post 403. The lower ends of the two spring pieces 405 are fixedly provided inside the threaded post 403, and the upper ends of the two spring pieces 405 are fixedly connected to the two telescopic posts 404 respectively.

[0039] Specifically, the tool holder top 401 connects the clamping mechanism 4 to the machine tool. The threaded column 403 is hollow inside, which facilitates the entry of the connecting mechanism 2. The threaded ring 402 can move up and down with the rotation of the thread. The threaded ring 402 can squeeze the telescopic column 404. When the telescopic column 404 is subjected to external force, it retracts inward and engages with the slot 202 to lock and fix the connecting mechanism 2. The inward and outward contraction of the telescopic column 404 can drive the bending of the spring piece 405. The elastic force of the spring piece 405 can also drive the telescopic column 404 to return to its original position.

[0040] Working principle: When fixing the milling cutter, the anti-slip mechanism 3 needs to be combined with the main body mechanism 1 first. The slide rod 306 is slid upward to disengage from the limiting groove 204 near the lower end. The slide rod 306 moves into the sliding groove 203. The slide rod 306 slides along the sliding groove 203 and can be moved into the limiting groove 204 near the upper end to re-limit the slide rod 306. During this process, the sliding ring 305 rotates and moves upward. The inner sleeve 304 is fitted in the rubber sleeve 301. At this time, the rubber sleeve 301 is in an expanded state. The tool holder 101 is inserted into the anti-slip mechanism 3. The tool holder 101 needs to pass through the oil absorption layer 205 first. The oil absorption layer 205 can clean the residual rust removal oil again. Since the surface of the inner sleeve 304 is relatively smooth, the tool holder 101 can be quickly and smoothly moved to the designated position.

[0041] Subsequently, the slide bar 306 is manipulated again to move it from the higher limiting groove 204 to the lower limiting groove 204. During this process, the inner sleeve 304 slides downward, the rubber sleeve 301 retracts to its original shape, and the outer sleeve 303 connected by the connecting rod 307 moves downward synchronously. The outer sleeve 303 compresses and tightens the rubber sleeve 301 from the outside to ensure the pressure of the rubber sleeve 301 on the tool holder 101, thereby ensuring the anti-slip effect of the anti-slip mechanism 3.

[0042] Next, the main body mechanism 1 is clamped and fixed by the clamping mechanism 4. The connecting sleeve 201 is put into the threaded column 403. The threaded ring 402 is rotated and moves downward along the threaded column 403 until the threaded ring 402 applies pressure to the telescopic column 404. The telescopic column 404 retracts inward until the telescopic column 404 is engaged in the slot 202, thus stably clamping the connecting mechanism 2.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
