Abstract
The utility model relates to a grooving cutter for a rotor for a single-screw-rod refrigeration compressor. The grooving cutter comprises a cutter main body, a cutter blade, a cutting edge, a cutter blade installing part and a notch part, wherein the cutter main body is approximately in a cylinder shape, a platform is arranged on the cutter main body, the cutter blade installing part is arranged at the front part of the cutter main body, the cutter blade is arranged on the cutter installing part, the cutter blade is parallel to the platform, the cutting edge is arranged at the front end part of the cutter blade and is in a circular arc shape, and the front part of the cutter main body is provided with the notch part. The grooving cutter for the rotor for the single-screw-rod refrigeration compressor has the advantages that the radian of the cutting edge is identical to the radian of a compression groove, the forming requirement of the compression groove can be met, meanwhile, the notch part is used for avoiding the appearance of the compression groove in the processing process, and the smooth proceeding of the processing of the compression groove can be ensured. Meanwhile, the grooving cutter has the advantages that the processing precision is high, the intensity of the cutter is high, and the rigidity is good.
Description
Technical field
The utility model relates to the grooving cutter of rotor of single used in screw bolt refrigerant compressor of a kind of machining accuracy height, cutter intensity height, good rigidity, belongs to the cutting tool technical field.
Background technology
At present, the most unmanageable in the single screw compressor is the Meshing Pair that is made of rotor and star-wheel.The accuracy of mesh of this Meshing Pair directly influences the complete machine performance of compressor; Rotor is as one of Meshing Pair critical component, and its working face is a space curved surface, and requirement on machining accuracy is high especially.
The current molding cutter turning method that generally adopts is processed, and promptly utilizes a dish type lathe tool to process, and this lathe tool is the same with the star-wheel tooth wide, and around rotating A=star-wheel radius+rotor radius with rotor center apart from the centre of gyration that is A; Rotor and dish type lathe tool are finished the turning of spiral compression groove according to 11:6 transmission accurately transmission recently with this.The major defect of this method is that mismachining tolerance is big, efficient is low, cutter intensity difference and add the high vibration that cause lathe man-hour easily.
The utility model content
The utility model purpose is the grooving cutter of rotor that has proposed single used in screw bolt refrigerant compressor of a kind of machining accuracy height, cutter intensity height, good rigidity in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of grooving cutter of rotor of single used in screw bolt refrigerant compressor comprises cutter body, blade, the edge of a knife, blade installation portion, notch part; It is cylindric that described cutter body roughly is; Described cutter body is provided with platform; Described blade installation portion is arranged on the front portion of cutter body; Described blade is arranged on the cutter installation portion; Described blade is parallel with platform; The described edge of a knife is arranged on the leading section of blade; The described edge of a knife is in the arc-shaped; The front portion of described cutter body is provided with notch part.
Preferably, the external diameter of described blade installation portion is less than the external diameter of cutter body.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage:
The grooving cutter of the rotor of single used in screw bolt refrigerant compressor of the present utility model, the radian of the edge of a knife is consistent with the radian of compression groove, can satisfy the moulding needs of compression groove, simultaneously, described notch part is used for dodging the profile of compression groove in process, can guarantee carrying out smoothly of compression groove processing; While the utility model machining accuracy height, cutter intensity height, good rigidity.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the stereogram of grooving cutter of the rotor of single used in screw bolt refrigerant compressor of the present utility model;
Wherein: 1, cutter body; 2, blade; 3, platform; 4, the edge of a knife; 5, blade installation portion; 6, notch part.
The specific embodiment
Be the grooving cutter of the rotor of single used in screw bolt refrigerant compressor described in the utility model as shown in Figure 1, comprise cutter body 1, blade 2, the edge of a knife 4, blade installation portion 5; Described cutter body 1 roughly is cylindric; Described cutter body 1 is provided with platform 3; Described blade installation portion 5 is arranged on the front portion of cutter body 1; Described blade 2 is arranged on the blade installation portion 5; Described blade 2 is parallel with platform 3; The described edge of a knife 4 is arranged on the leading section of blade 2; The described edge of a knife 4 is in the arc-shaped; The front portion of described cutter body 1 is provided with notch part 6; The external diameter of described blade installation portion 5 is less than the external diameter of cutter body 1.
The grooving cutter of the rotor of single used in screw bolt refrigerant compressor of the present utility model, the radian of the edge of a knife is consistent with the radian of compression groove, can satisfy the moulding needs of compression groove, simultaneously, described notch part is used for dodging the profile of compression groove in process, can guarantee carrying out smoothly of compression groove processing; While the utility model machining accuracy height, cutter intensity height, good rigidity.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
