Abstract
Description
Technical Field
[0001] The utility model relates to a gear shaping cutter with replaceable carbide blades. Background Art
[0002] In the production of gear parts, the internal teeth and the cutter form short external teeth, which are generally processed by the gear shaping process. The gear shaping cutters are divided into disc-shaped straight gear shaping cutters, bowl-shaped straight gear shaping cutters and tapered shank straight gear shaping cutters, and all of them are made of solid high-speed steel.
[0003] Materials with a large number of teeth, high tooth surface hardness, and high Cr content in the gear blanks cause greater tool wear and significantly affect gear accuracy. Furthermore, if tool life is too short, it increases component production costs and reduces the company's competitiveness. Summary of the Invention
[0004] In order to solve the above technical problems, the utility model provides a gear shaping cutter with replaceable carbide blades which has a simple structure and is easy to replace.
[0005] The utility model provides a technical solution to the above technical problems: a gear shaping cutter with replaceable carbide blades, comprising a cutter body, one end of which is fixedly connected to a gear shaping device, and the other end of which is evenly distributed with a plurality of carbide blades in a circumferential direction, and the carbide blades are fixed to the cutter body by bolts.
[0006] The above-mentioned replaceable carbide blade gear shaping cutter has a single-side tooth thickness of the carbide blade greater than the standard tooth thickness by 0.2-0.3 mm before grinding.
[0007] For the above-mentioned replaceable carbide blade gear shaping cutter, under the condition that the full tooth height remains unchanged, the tool tooth thickness corresponding to the standard gear is 0.5πm, π is 3.1415, m is the module, and the tooth thickness of the carbide blade corresponding to the gear to be ground is 0.5πm-0.6, and the tooth thickness unit is millimeter.
[0008] The above-mentioned replaceable carbide blade gear shaping cutter has the carbide blade accurately positioned in an oblique V shape.
[0009] The beneficial effects of this utility model are as follows: the utility model uses a universal gear shaping cutter structure as the main body, and after slotting, the carbide blades are connected by bolts. The carbide blades can be customized according to the standard tooth shape (parameters include module and pressure angle). The carbide blades are precisely positioned in an oblique V shape to ensure the consistency of the position of each blade. When the carbide blades need to be replaced, all the carbide blades of the tool corresponding to the standard gear need to be replaced (the grinding parameters remain unchanged). Only the worn carbide blades need to be replaced for the gear that needs to be kept. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural diagram of the present utility model.

[0012] Figure 3 for Figure 1 Schematic diagram of the structure of medium carbide inserts. DETAILED DESCRIPTION
[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1-Figure 3 As shown, a gear shaping cutter with replaceable carbide blades includes a tool body 1, one end of the tool body 1 is fixedly connected to the gear shaping equipment, and the other end of the tool body 1 has a plurality of carbide blades 2 evenly distributed circumferentially, and the carbide blades 2 are fixed to the tool body 1 by bolts 3.
[0015] The carbide blade 2 can be customized according to the standard tooth shape (parameters include module and pressure angle). The carbide blade 2 is accurately positioned in an oblique V shape to ensure the consistency of the position of each blade.
[0016] The tool tooth profile parameters are determined based on product parameters such as whether the tooth profile is left to be ground, whether the tooth height is shortened, and tooth displacement. The single-side thickness of the carbide blade 2 before grinding is 0.2-0.3 mm larger than the standard tooth thickness, and then the entire circle of the tool blade tooth profile is ground using a grinding wheel gear grinder.
[0017] When the full tooth height remains unchanged, the tool tooth thickness corresponding to the standard gear is 0.5πm, π is 3.1415, m is the module, and the tooth thickness of the carbide blade 2 corresponding to the gear to be ground is 0.5πm-0.6, and the unit of tooth thickness is millimeter.
[0018] When the carbide blade 2 needs to be replaced, for the tool corresponding to the standard gear, all its carbide blades 2 need to be replaced (the grinding parameters remain unchanged). For the gear that needs to be ground, only the worn carbide blade 2 needs to be replaced, and then the single-tooth blade can be ground (the accuracy can be reduced by 1 level) to basically keep it consistent with the other carbide blades 2.
