Embodiment 1

[0032] Such as figure 1 As shown, a double-body processing method of a screw rotor in this embodiment includes the following steps:

[0033] Step 1. According to the design size of the screw rotor, the length of the raw material of the screw rotor is roughly machined into the length of two connected screw rotors to form a double-body screw rotor. The axial middle part of the two connected double-body screw rotors is the exhaust end shaft of the two screw rotors, and the two ends of the axial direction are the intake end shafts of the double-body screw rotor. The length of the exhaust end shaft is There is a sawing off and a finishing allowance for the shaft head of the exhaust end. During processing, first process the diameter of the helical part of the double-body screw rotor, then process the shaft diameters of the intake ends at both ends of the double-body screw rotor, and finally process the shaft diameters of the two connected exhaust ends located in the middle of the d...

Embodiment 2

[0040] Such as Figure 2 ~ Figure 3 As shown, the screw rotor double-body processing device of this embodiment includes a drive head 2 connected to the drive head of the helical milling machine, a hydraulic tailstock 3 arranged at the tail end of the helical milling machine, and is arranged above the helical milling machine and located at the drive head 2 and the hydraulic tailstock. The milling cutter disc drive mechanism 4 between the seats 3.

[0041] The inner cavity of the driving head 2 is provided with a driving head tip 5, which is used to support and position the shaft head at one end of the screw rotor 1, and the driving head 2 uses a clamping device to clamp the shaft head at one end of the screw rotor 1 to process the screw rotor When the spiral of 1 drives the screw rotor 1 to rotate.

[0042] The tailstock center 6 is connected to the side of the hydraulic tailstock 3 facing the drive head, the tailstock center 6 is concentric with the axis of the drive head 5, ...

Abstract

The invention discloses a screw rotor double-body machining method. The screw rotor double-body machining method comprises the following steps that 1, the length of a screw rotor raw material is roughly machined into the length of two screw rotors which are connected into a whole to form a double-body screw rotor; 2, central holes of air inlet end shaft heads at the two ends of the double-body screw rotor are machined; 3, spirals of the two parts of the double-body screw rotor on a spiral milling machine are machined; 4, the double-body screw rotor subjected to the two spiral milling procedures is cut off; 5, center holes in the shaft heads of the exhaust ends of the two independent screw rotors which are cut off are machined; and 6, the two independent screw rotors cut off are subjected to outer circle grinding and molded line grinding machining procedures, and finished screw rotors are machined. The invention further discloses a screw rotor double-body machining device. The problem that the small screw rotor cannot be machined in the machining process is effectively solved, material waste caused by adopting a method of lengthening raw materials is made up, the material cost and the manufacturing cost are saved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of compressor screw rotor production, and in particular relates to a double-body processing method and a processing device of a screw rotor. Background technique [0002] The screw rotor after rough machining needs to be helically processed. Due to the short head of the exhaust end of some small screw rotors, the drive head of the helical milling machine cannot clamp the small screw rotor exhaust end shaft when processing on a special milling machine for the upper screw. Even if it can be clamped, in the process of helical milling, the milling cutter disc will interfere with the drive head of the helical milling machine when the milling cutter disc is out of the knife, and the screw rotor cannot be completely processed. At present, the method of lengthening the exhaust end shaft of the small screw rotor is generally adopted, and the small screw rotor is helically milled. After the helical milling is complet...
