Description
Technical Field
[0001] This utility model relates to the technical field of bar end mill grinding and repair, specifically a bar end mill grinding and repair device with a protective structure. Background Technology
[0002] A bar end mill is a cutting tool widely used in metal cutting. It usually consists of a cylindrical cutter body and a certain number of cutting teeth. When in use, it mills the workpiece through its own rotational motion. During long-term use, the cutting edge of the bar end mill wears down, so it needs to be maintained with the help of a grinding and maintenance device.
[0003] As disclosed in announcement number CN222661008U, a grinding and maintenance device for bar end mills belongs to the field of bar end mill maintenance technology. It includes a base plate and an electric slide table mounted on one side of the top of the base plate. A drive motor is installed on one side of the electric slide table. The guiding structure includes a fixed frame fixed to one side of the mounting table, a movable seat sliding inside the fixed frame, a fixed component at the top of the movable seat, and guide teeth at the top of the fixed component. In this invention, the position of the guide teeth is adjusted by sliding the movable seat inside the fixed frame. By rotating the rotating shell, the guide teeth are inserted into the spiral groove of the bar end mill, restricting the movement path of the bar end mill. This achieves the movement guiding function of the device, facilitating the guidance of the movement of the bar end mill, ensuring that the cutting edge of the bar end mill is always in contact with the grinding wheel, improving the grinding effect of the bar end mill, and reducing the difficulty of operating the device, making it more convenient to use.
[0004] However, existing technologies have the problem that it is inconvenient to grind and repair different positions of end mills of different lengths, and that dust and debris fly out during the grinding process, which can easily cause injury to the operators nearby. For example, the comparative patents listed above have this problem.
[0005] To address this issue, we propose a grinding and maintenance device for bar end mills with a protective structure. Utility Model Content
[0006] The purpose of this invention is to provide a grinding and maintenance device for bar end mills with a protective structure, in order to solve the problems mentioned in the background art, such as the inconvenience of grinding and maintaining different positions of bar end mills of different lengths, and the fact that dust and debris fly outwards during the grinding process, which can easily cause injury to the operators nearby.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a grinding and maintenance device for bar end mills with a protective structure, comprising a base, a support plate, a first motor, and a grinding disc;

Detailed Implementation
[0029] 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.
[0030] Please see Figures 1-6 .
[0031] To address the problems in existing technologies where it is inconvenient to grind and repair different positions of bar end mills of different lengths, and where dust and debris fly outwards during grinding, potentially injuring nearby operators, this solution provides a bar end mill grinding and repair device with a protective structure. The device comprises a base 1, a support plate 2, a first motor 3, and a grinding disc 4. A conveyor baffle 7 has linear guide rails 8 for limiting movement slidably connected to its lower left and right sides. The conveyor baffle 7 moves back and forth at the upper end of the base 1. Side baffles 10 are fixedly connected to the upper left and right sides of the conveyor baffle 7, and both the conveyor baffle 7 and the side baffles 10 cover the outside of the bar end mill. A bar end mill is inserted into a connecting column 13, and a support plate 14 is provided inside the connecting column 13. The support plate 14 moves up and down within the connecting column 13. Arc-shaped clamping plates 18 are provided on the upper left and right sides of the connecting column 13 for clamping.
[0032] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, firstly, according to the length of the end mill and the grinding position, the fixing rod 15 is pulled up or down, and the fixing rod 15 slides up and down with the connecting post 13. The fixing rod 15 drives the support plate 14 to move up and down inside the connecting post 13, adjusting the position of the support plate 14 in the connecting post 13. At this time, the grinding position extends above the connecting post 13. Then, by rotating the fixing cap 16 threaded to the outer surface of the fixing rod 15, the fixing cap 16 is fitted to the rear end of the connecting post 13, limiting the position between the fixing rod 15 and the connecting post 13, thereby fixing the support plate 14. Then, the end mill to be ground is inserted into the connecting post 13, and the bottom of the end mill is placed on the support plate 14. Then, the connecting bolts 17 threaded to the left and right sides of the upper end of the connecting post 13 are rotated, and the connecting bolts 17 rotate with the arc-shaped clamping plate 18. The connecting bolts 17 push the arc-shaped clamping plate 18 to move inside the connecting post 13 to stably clamp the end mill and improve the stability of the end mill during the grinding process.
[0033] Then start the first motor 3 installed on the upper end of the support plate 2, such as... Figure 1 , Figure 2 and Figure 3 As shown, the first motor 3 drives the grinding disc 4 to rotate within the mounting cover 5. Then, the electric telescopic rod 6, installed on the front side of the upper end of the base 1, is activated. The electric telescopic rod 6 pushes the conveying baffle 7 to slide stably between the conveying baffle 7 and the linear guide rail 8 fixed on the upper end of the base 1. The conveying baffle 7 drives the bar end mill to move backward for feeding and conveying. When the bar end mill contacts the rotating grinding disc 4, it performs grinding and maintenance. Furthermore, the second motor 12, installed on the lower end of the base plate 11, is activated. The second motor 12 drives the connecting column 13 to rotate, thereby rotating the bar end mill for rotational grinding and maintenance. Moreover, the conveying baffle 7 and the side baffle 10, which cover the outside of the bar end mill, can prevent dust and debris flying outward during the grinding process from injuring the operator nearby. The operator can observe the grinding process through the transparent observation window 9.
[0034] 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.
