Abstract
The utility model belongs to the field of machining, and particularly relates to a combined tool for machining holes in a crank. The combined tool for machining the holes in the crank comprises a combined tool body. The combined tool body comprises a cutting edge and a handle portion; the cutting edge comprises a drill point, a boring cutter and a chamfer mill. The drill point is arranged at the top end of the cutting edge, the boring cutter is connected with the drill point, the chamfer mill is connected with the boring cutter, the handle portion is connected with the chamfer mill, and the central axis of the drill point, the central axis of the boring cutter, the central axis of the chamfer mill and the central axis of the handle portion coincide; chip grooves are formed in the circumferential face of the combined tool body. Machining of the central hole, the locating hole and a hole chamfer is accomplished through one-time clamping of the combined tool on one device, the coaxiality of the central hole, the locating hole and the hole chamfer is guaranteed, the accuracy of the stepped hole of the crank is good, the production cost is reduced, and the production efficiency is improved.
Description
Technical field
The utility model belongs to field of machining, especially relates to a kind of gang tool for the processing of bent axle mesopore.
Background technology
When a plurality of stepped holes on axle class centre bore are processed, minute a plurality of operations are processed now.Centering, boring locating hole, three operations of orifice chamfer are divided clamping No. three times, on three equipment, process.Through after processing repeatedly, the form and position tolerances such as axiality etc. are less than assurance, processed complex and need multiple devices to process it, and production efficiency is low and production cost is higher.
Utility model content
The purpose of this utility model is to solve the deficiencies in the prior art part, and a kind of gang tool for the processing of bent axle mesopore of centering, boring locating hole and orifice chamfer is simultaneously provided.
The purpose of this utility model solves by following technical proposal:
A gang tool for the processing of bent axle mesopore, comprises gang tool body, it is characterized in that: described gang tool body comprises cutting edge and shank; Described cutting edge comprises apex point, boring cutter and rose reamer, and apex point is in cutting edge top, and boring cutter is connected with apex point, and rose reamer is connected with boring cutter, and shank is connected with rose reamer, and the central shaft of apex point, boring cutter, rose reamer and shank overlaps; The side face of described gang tool body is provided with chip area.
Apex point described in the utility model, boring cutter, rose reamer and shank are one-body molded.
The cutting edge inclination ε of apex point described in the utility model is 120 °; The cutting edge inclination α of boring cutter is 60 °; The cutting edge inclination β of rose reamer is 60 °.
Compared to the prior art the utlity model has following characteristics and beneficial effect:
1, on an equipment, pass through clamped one time, complete the processing of centre bore, locating hole and orifice chamfer, guaranteed three's axiality, make bent axle stepped hole precision better.
2, only need an equipment, cutter, a time processing just can complete the processing to bent axle stepped hole, reduced production cost, improved production efficiency.
Accompanying drawing explanation
Fig. 1 is that the utility model structure is schematic diagram.
Fig. 2 is cutting edge place structural representation.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further details.
As shown in Figure 1, a kind of gang tool for the processing of bent axle mesopore, comprises gang tool body 1, and described gang tool body 1 comprises cutting edge 2 and shank 3.Described cutting edge 2 comprises apex point 4, boring cutter 5 and rose reamer 6, apex point 4 is in cutting edge 2 tops, boring cutter 5 is connected with apex point 4, rose reamer 6 is connected with boring cutter 5, shank 3 is connected with rose reamer 6, the central shaft of apex point 4, boring cutter 5, rose reamer 6 and shank 3 overlaps, and has guaranteed the axiality of the interior each several part of stepped hole of processed bent axle.Apex point 4 described in the utility model, boring cutter 5, rose reamer 6 and shank 3 are one-body molded.While wanting processing step hole, directly gang tool body 1 is installed on a set of equipment, the disposable processing that completes centre bore, locating hole and orifice chamfer, simple to operate, precision is high.
The side face of described gang tool body 1 is provided with chip area 7.
As shown in Figure 2, the cutting edge inclination ε of apex point 4 described in the utility model is 120 °; The cutting edge inclination α of boring cutter 5 is 60 °; The cutting edge inclination β of rose reamer 6 is 60 °.
