Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, and particularly relates to a special tool for processing ultra-wide tooth surfaces. Background Technique

[0002] A gear refers to a mechanical element with teeth on the rim that continuously mesh to transmit motion and power. Gear processing refers to the process of converting raw materials into gears with specific tooth shapes and dimensions through a series of technological processes and technical means. This process involves multiple aspects, including gear design, material selection, processing technology selection, and subsequent heat treatment, etc. In the process of gear processing, a broaching cutter is often used to process the ultra-wide tooth surface of the gear.

[0003] For example, the Chinese utility model provides "a broaching cutter with wear-resistant and durable multi-coatings", the publication number: CN216541229U. This application includes cutter teeth and a taper shank. One end of the cutter teeth is fixedly connected to the taper shank. A protective sleeve is sleeved outside the cutter teeth. An installation sleeve is arranged on the back side of the protective sleeve. A locking mechanism is arranged on the installation sleeve. A receiving groove is opened on the inner wall of the protective sleeve. An outer protective pad is fixedly connected to the outer peripheral side wall of the protective sleeve. A fixing ring is fixedly connected to the back side of the protective sleeve. One side of the fixing ring is fixedly connected to the installation sleeve. In the utility model, by arranging a protective sleeve outside the cutter teeth and matching the cutter teeth into the inner side of the receiving groove, the protective sleeve can provide an effective protective effect on the cutter teeth, avoiding the impact on the cutter teeth before installation. And a plurality of outer protective pads are arranged on the outer wall of the protective sleeve, which can prevent the cutter teeth from rolling. The inside of the outer protective pad is hollow and has good buffering performance, improving the protective effect on the cutter teeth.

[0004] Although the broaching cutter in the above technology can improve the protective effect on the cutter teeth, during the long-term processing of the ultra-wide tooth surface of the gear, the cutter teeth often get damaged. And since the cutter teeth are integrally made, when the cutter teeth are damaged, the whole needs to be replaced, thus greatly increasing the usage cost of personnel and unable to meet the usage needs of personnel.

[0008] As a preferred solution, a rubber protective strip is fixedly connected to the outer surface of the protective shell. The shape of the rubber protective strip is arc-shaped.

[0009] As a preferred solution, positioning blocks are fixedly connected to both sides of the annular groove. A positioning hole is provided in the middle of the arc-shaped fixing plate. The surface of the positioning block is movably connected to the surface of the positioning hole.

[0010] As a preferred solution, an installation tool handle is fixedly connected to the middle of the top of the fixed disk. Between the lower end of the installation tool handle and the top of the fixed disk, a reinforcing plate is fixedly connected.

[0011] As a preferred solution, the number of the reinforcing plates is four, and the included angles between adjacent two reinforcing plates are equal.

[0027] Embodiment 2:

[0028] On the basis of Embodiment 1, the utility model is as shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 . The bottom of the fixed disk 1 is movably connected with a protective shell 6. A rubber protective sleeve 5 is fixedly connected to the inner cavity of the protective shell 6. The inner surface of the rubber protective sleeve 5 is movably connected to the surface of the cutter teeth 4. A rubber protective strip 7 is fixedly connected to the outer surface of the protective shell 6. The rubber protective strip 7 is arc-shaped. Positioning blocks 12 are fixedly connected to both sides of the annular groove 13. A positioning hole 11 is opened in the middle of the arc-shaped fixing plate 10.

Limit disks 18 are fixedly connected to both ends of the L-shaped clamping rod 16. The surface of the limit disk 18 is movably connected to the inner cavity of the fixed cylinder 19.

[0029] In this technical solution, through the arrangement of the protective shell 6 and the rubber protective sleeve 5, the periphery of the cutter teeth 4 can be effectively protected, and the probability that the cutter teeth 4 are damaged by collision during the moving and transporting process of the whole is effectively reduced. Through the arrangement of the rubber protective strip 7, the periphery of the protective shell 6 can be effectively protected. Through the arrangement of the positioning block 12 and the positioning hole 11, the arc-shaped fixing plate 10 can be effectively positioned, avoiding the dislocation of the arc-shaped fixing plate 10 during the installation process. Through the arrangement of the reinforcing plate 8, the connection strength between the installation tool handle 9 and the fixed disk 1 is effectively improved. Through the arrangement of the limit disk 18, the L-shaped clamping rod 16 and the fixed cylinder 19 can be effectively limited, avoiding the up and down displacement of the L-shaped clamping rod 16 along the surface of the fixed cylinder 19.

[0030] The working principle of the present utility model is as follows: Through the arrangement of the limit pin column 2 and the pin hole 14, effective locking and limiting can be carried out among the fixed disk 1, the annular groove 13, the arc-shaped fixing plate 10 and the cutter teeth 4, so as to avoid the offset of the cutter teeth 4 during the processing of the ultra-wide tooth surface.
