specific Embodiment approach 1

[0014] Cutter head, angular positioning pin, two compression screws, cutter head, washer, and pull stud. The screw is clamped in the radial direction, and two compression screws are placed on the rear end of the hole of the cutter head, and the pull nail is passed through the washer, and is tightened in the threaded hole at the rear end of the cutter head. The cutter heads mentioned above are clamped on the cutter head. When using the assembled cutter head, the 24 cutter heads on the circumference are adjusted to meet the axial requirements. Use a torque wrench to ensure that the force used in the adjustment process is consistent. It is transferred to the special cutter shaft through the clamping hole of the cutter head. The outer diameter of the cutter shaft is a standard taper of 1:24, and the clamping hole is also a standard taper of 1:24. The accuracy is determined by the ring gauge and the plug gauge respectively. To ensure the requirements of the product, assemble it on ...

specific Embodiment approach 2

[0016] For the clamping of the cutter head, it should be noted that the outer diameter of the cutter head should be guaranteed to be 0.01, and the outer diameter of the corresponding hole on the cutter head should be matched at +0.01 to ensure clearance fit. The angle between the bevel and the cutter teeth is very important. The angular tolerance is 5 minutes. The larger the diameter of the cutter head, the stricter the angular requirements. It can be ground to ensure the size requirements. The dimensions of the 24 cutter heads must be consistent, especially the height of the cutter teeth. The tolerance is 0.02, and the beating of the cutter head after assembly ensures the use requirements of the product.

[0017] The tolerance of the angular surface profile on both sides of the cutter tooth part of the cutter head is 0.008, and the outer diameter of the tooth tip after the cutter tooth is assembled is guaranteed. The size of a single cutter tooth must be consistent with a tole...

[0020] When the cutter head is in use, the positions of the 24 holes are required to be evenly distributed at 0.02. The detailed clamping process is as follows: first put the cutter head into the clamping hole of the cutter head, and interact with the angular positioning pin to form an angular direction. Locate, then tighten the two compression screws, pass the pull stud through the washer, and tighten it into the threaded hole at the rear end of the cutter head. The cutter head is fixed to the cutter shaft through the cutter head clamping hole to ensure the axial and radial runout requirements of the product clamping. After the cutter head is clamped to the cutter shaft, the cutter head is fixed to the cutter shaft through the cutter head fixing hole. , before fixing, the direction of the cutter head should be fixed through the positioning pin hole of the cutter head angle.

[0021] The clamping taper hole of the cutter head is the benchmark for the use of the entire tool pro...

Abstract

The invention discloses a spiral bevel gear rough milling cutter product. The spiral bevel gear rough milling cutter product comprises cutter heads, an angular positioning pin, two compression screws,a cutter disc, a gasket and a blind rivet, and is characterized in that the cutter heads are clamped on the cutter disc, the angular direction is determined through the angular positioning pin, clamping is conducted in the radial direction through the two compression screws, the two compression screws are placed on the rear end face of a hole of the cutter disc, and the blind rivet penetrates through the gasket and is screwed into threaded holes in the rear ends of the cutter heads. The cutter heads are clamped on the cutter disc and are uniformly distributed at 24 positions in the circumferential direction to form cutter teeth of the product, the assembled product is ensured to meet the requirements that the axial run-out requirement is 0.04 and the radial run-out is 0.02, and the clamped cutter disc is clamped on a special cutter shaft. The spiral bevel gear rough milling cutter product mainly aims to change the structural shapes of the cutter disc and the cutter teeth and reduce the machining difficulty of the cutter teeth. Therefore, a universal high-precision grinding machine can be used for machining products.

Description

technical field [0001] The invention patent relates to the field of gear processing. Background technique [0002] The structure of the traditional cutter head and cutter teeth requires professional and high-precision equipment to complete, and ordinary non-standard cutter manufacturers cannot complete the processing of cutter teeth: [0003] This project is mainly to change the structure and shape of the cutter head and cutter teeth to reduce the processing difficulty of the cutter teeth. The processing of the product can be realized by using a general-purpose high-precision grinding machine. [0004] Technical issues The accuracy of the main cutter head: including the position accuracy of the positioning hole (equal division and position degree), the consistency of the cutter tooth processing, the axial parallelism requirements of the positioning pin and the cutter head. Contents of the invention [0005] Using a new cutterhead structure (positioning, cutter tooth stru...
