Description

Technical Field

[0001] This utility model relates to the field of woodworking milling cutter technology, specifically to a woodworking milling cutter cutting edge. Background Technology

[0002] With the development of modern industry, there are increasingly more types of woodworking milling cutters. Currently, based on the structure of their cutting edges, woodworking milling cutters are mainly divided into integral cutters where the cutting edge and the cutter body are integrated, toothed cutters where the cutting edge and the cutter body are separate, and welded cutters. Integral cutters are suitable for machining small parts, and their reusability and cutting depth are lower than those of toothed cutters and welded cutters. Toothed cutters and welded cutters are mostly used for machining with large depths of cut. Among them, toothed cutters have high insert installation precision, but the cutting groove of the cutter body is complex to machine and has a high manufacturing cost. In addition, fine-tuning is required after the insert is installed. Milling cutters are frequently used in woodworking.

[0003] Most existing woodworking milling cutters are integral pieces. After the cutting edge on one side is sharpened, it needs to be replaced or ground, which is time-consuming and affects the efficiency of the operation. At the same time, frequent replacements make the cost too high. In addition, most existing milling cutters have threaded cutting edges, but if the cutting edge is not sharp, it will easily make the cut surface of the wood rough and affect the appearance. Therefore, it is necessary to provide a new type of woodworking milling cutter cutting edge to solve the above technical problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a woodworking milling cutter cutting edge that has the advantages of preventing detachment and increasing service life, and the vertical cutting edge improving the flatness of the cut surface, thus solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a woodworking milling cutter cutting edge, comprising: a milling cutter body, four vertical cutting edges on the outside of the milling cutter body, a handle on the top of the milling cutter body, threaded holes on both ends of the milling cutter body, a threaded head fixedly connected to the bottom of the handle, a slider slidably connected inside the handle, and locking blocks fixedly connected to the outer sides of both sides of the slider, four locking grooves on the outside of the milling cutter body, and a cavity inside the handle. In use, the entire device is assembled with the main unit via the handle. After assembly, the milling cutter body rotates at high speed, causing the cutting edge to be angled... The two vertical cutting edges fit snugly against the wood during operation. The vertical cutting edges allow for a closer fit when working with the wood, preventing burrs on the cut surface and improving aesthetics. When the two oblique vertical cutting edges become dull, the entire milling cutter body can be inverted and spliced ​​by combining the threaded head and threaded hole, allowing the other two unused vertical cutting edges to continue working, thereby increasing the service life of the overall device. During use, the locking block is engaged inside the slot, ensuring that the handle and the milling cutter body do not rotate relative to each other, preventing the threaded head from rotating inside the threaded hole and falling off, thus improving the stability of the overall device during use.

[0006] Preferably, the vertical cutting edges are arranged in pairs on the outside of the milling cutter body. When in use, the milling cutter body rotates in the same direction, which allows the two oblique vertical cutting edges to work and consume simultaneously, while the other two oblique vertical cutting edges stop working.

[0007] Preferably, the threaded head can be completely locked inside the threaded hole, and the threaded holes at both ends of the milling cutter body are of the same size and depth. The threaded head can be threaded into different threaded holes, allowing the milling cutter body to be used upside down, and enabling the switching of two vertical cutting edges with different inclinations.

[0008] Preferably, the four slots are provided in pairs on the outside of both ends of the milling cutter body, and the two slots on the outside of both ends of the milling cutter body are opposite each other, and the locking block can be completely locked inside the slot.

[0009] Preferably, the outer side of the milling cutter body has two sliding grooves, and the two locking blocks are respectively locked inside the two sliding grooves. The sliding grooves can limit the sliding trajectory of the locking blocks, so that the locking blocks can be completely locked inside the sliding grooves.

[0010] Preferably, a return spring is fixedly connected to the top of the slider, and a circular hole is opened inside the slider. The elastic force of the return spring can make the entire slider always move downward, and at the same time, it can make the locking block always locked inside the slot.

[0011] Preferably, a reinforcing post is fixedly connected inside the handle. The reinforcing post is located inside the cavity of the handle. The reinforcing post can increase the integrity of the cavity and prevent the excessively large cavity inside the handle from affecting its rigidity and hardness.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] I. In use, the entire device is assembled with the main unit via the handle. After assembly, the milling cutter body rotates at high speed, causing the two oblique vertical cutting edges to fit closely to the wood. The vertical cutting edges allow for a closer fit when working with the wood, preventing burrs on the cut surface and improving aesthetics. When the two oblique vertical cutting edges become dull, the entire milling cutter body can be inverted and spliced ​​using a combination of a threaded head and a threaded hole, allowing the other two unused vertical cutting edges to continue working, thereby increasing the service life of the entire device.

[0014] Second, in the process of using this utility model, the locking block is locked inside the slot, which can lock the handle and the milling cutter body together and prevent relative rotation, thus avoiding the threaded head from rotating inside the threaded hole and falling off, and improving the stability of the overall device during use.

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.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a woodworking milling cutter cutting edge, comprising: a milling cutter body 1, four vertical cutting edges 2 on the outside of the milling cutter body 1, a handle 3 on the top of the milling cutter body 1, threaded holes 4 on both ends of the milling cutter body 1, a threaded head 5 fixedly connected to the bottom of the handle 3, a slider 9 slidably connected inside the handle 3, and locking blocks 8 fixedly connected to the outside of both sides of the slider 9, four locking grooves 7 on the outside of the milling cutter body 1, and a cavity inside the handle 3. In use, the entire device is assembled with the main unit via the handle 3. After assembly, the milling cutter body 1 rotates at high speed, causing the two oblique vertical cutting edges 2 to... The wood lamination process utilizes vertical cutting edges 2 to ensure a closer fit to the wood, preventing burrs on the cut surface and improving aesthetics. When the two oblique vertical cutting edges 2 become dull, the entire milling cutter body 1 can be inverted and spliced ​​by combining the threaded head 5 and the threaded hole 4. This allows the other two unused vertical cutting edges 2 to continue working, thereby increasing the overall lifespan of the device. During use, the locking block 8, which is engaged with the slot 7, prevents the handle 3 from rotating relative to the milling cutter body 1, thus preventing the threaded head 5 from rotating inside the threaded hole 4 and falling off, and improving the stability of the entire device during use.

[0023] The vertical cutting edges 2 are arranged in pairs on the outside of the milling cutter body 1. When in use, the milling cutter body 1 rotates in the same direction, which allows the two oblique vertical cutting edges 2 to work and consume at the same time, and at the same time, the other two oblique vertical cutting edges 2 to stop working.

[0024] The threaded head 5 can be completely locked inside the threaded hole 4. The threaded holes 4 at both ends of the milling cutter body 1 are the same size and depth. The threaded head 5 can be threaded inside different threaded holes 4, which allows the milling cutter body 1 to be used upside down, so as to switch between two vertical cutting edges 2 with different inclinations.

[0025] Four slots 7 are opened in pairs on the outside of both ends of the milling cutter body 1. The two slots 7 on the outside of both ends of the milling cutter body 1 are opened opposite each other, and the locking block 8 can be completely locked inside the slot 7.

[0026] The outer side of the milling cutter body 1 has two sliding grooves 6, and two locking blocks 8 are respectively locked inside the two sliding grooves 6. The sliding grooves 6 can limit the sliding trajectory of the locking blocks 8, so that the locking blocks 8 can be completely locked inside the sliding grooves 6.

[0027] A return spring 10 is fixedly connected to the top of the slider 9. A round hole 12 is opened inside the slider 9. The elastic force of the return spring 10 can make the entire slider 9 always downward, and at the same time, it can make the locking block 8 always locked inside the locking slot 7.

[0028] When the woodworking milling cutter is in use, the vertical cutting edge 2 allows for a closer fit to the wood during operation, preventing burrs on the cut surface and improving aesthetics. When the two oblique vertical cutting edges 2 become dull, the entire milling cutter body 1 can be inverted and spliced ​​by combining the threaded head 5 and the threaded hole 4, allowing the other two unused vertical cutting edges 2 to continue working.

[0029] Please see Figures 1 to 4 This utility model provides a technical solution: a woodworking milling cutter cutting edge, wherein a reinforcing post 11 is fixedly connected inside the handle 3. The reinforcing post 11 is located inside the cavity of the handle 3. The reinforcing post 11 can increase the integrity of the cavity and avoid the excessively large cavity inside the handle 3 from affecting its rigidity and hardness.

[0030] When the cutting edge of this woodworking milling cutter is in use, the locking block 8 is locked inside the slot 7, which can lock the handle 3 and the milling cutter body 1 together and prevent relative rotation, thus avoiding the threaded head 5 from rotating inside the threaded hole 4 and falling off.

[0031] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the specification and drawings can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
