Abstract
The invention discloses an internal reamer and a machining method of a water-pump circulating pipe. The internal reamer comprises a plurality of blades and a hollow cylindrical handle, wherein the inner surface of the cylindrical handle is provided with a plurality of blade installing grooves for installing the blades at equal distance, and the outer surface of the cylindrical handle is provided with screw countersinks. According to the machining method of the water-pump circulating pipe provided by the invention, the internal reamer is directly used for machining the excircle of the water-pump circulating pipe, and when the axial machining length of the water-pump circulating pipe reaches 30mm-70mm, the internal reamer starts to be retracted. The invention has the beneficial effects that when the internal reamer is used for machining the water-pump circulating pipe, a prismatoidal edge of the internal reamer is closely attached with the outer surface of the water-pump circulating pipe all the time, simultaneously the edge can not generate extrudingforce to the outer surface of the water-pump circulating pipe in the machining process, and when the force acting on the internal reamer is changed instantly, the chatter marks can not be generated on the outer surface of the water-pump circulating pipe, so that the machining accuracy of the outer surface of the water-pump circulating pipe can be effectively improved.
Description
Technical field
The present invention relates to cutter field, particularly relating to a kind of processing method for processing reamer and water pump circulation pipe in water pump upper circular tube.
Background technology
Operationally, the end of its circulation pipe needs to connect plastic flexible pipe water pump, if the inadequate rounding of the outer surface of the end of circulation pipe, plastic flexible pipe connects above, can there is junction and can not fit tightly and occur leaking; If the error of the outer surface of the end of circulation pipe is too large, plastic flexible pipe will be easy to landing or very difficult socket is got on.
Current processing water pump circulation pipe cylindrical generally adopts the method for lathe or Boring machine processing, due to the circulation pipe not heart within the workpiece, rotating diameter is large, large-scale lathe or boring machine need be adopted to complete processing, also need to make frock station pump simultaneously, due to bias, if add water pump imbalance in man-hour, easily cause vibrations, the product surface of processing has irregular ripple to produce, make the roughness of circulation pipe outer surface seriously overproof, and comparatively large to lathe injury, often to take in frock counterweight to keep dynamic balancing in processing.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides the processing method of a kind of interior reamer and water pump circulation pipe, use this interior reamer and processing method can improve the machining accuracy of water pump circulation pipe outer surface, its technical scheme is as follows:
Reamer in a kind of, for processing water pump circulation pipe, is characterized in that: the cylinder handle of a knife comprising some blades and a hollow; The inner surface of described cylinder handle of a knife is equally spaced is provided with several for installing the blade installation slot of blade, and the outer surface of cylinder handle of a knife is provided with screw cone hole.
Further, described blade is by being fixedly connected with integral blade body and blade forms; Described blade is prismatic, and blade two ends opposing blades body is provided with chamfering.
Further, the lower edges place of described cylinder handle of a knife is provided with chamfering.
Further, the outer surface of cylinder handle of a knife is also provided with a V-type groove.
A processing method for water pump circulation pipe, is characterized in that: in using, reamer adds man-hour to water pump circulation pipe,
The first step, determines the center line of water pump circulation pipe and the center line alignment of interior reamer;
Second step, then in reamer with 200r/min ~ 300r/min rotate while with the speed feed of 30mm/min;
3rd step, starts at the uniform velocity withdrawing after the axial processing length of water pump circulation pipe reaches 30-70mm;
When using interior reamer to process water pump circulation pipe, the machining accuracy of circulation pipe outer surface is-0.1mm ~ 0.1mm, and roughness is Ra6.3.
Beneficial effect of the present invention is, when using this interior reamer processing water pump circulation pipe, the prismatic blade of interior reamer is fitted with the intimate of water pump circulation pipe all the time in process, blade can not produce extruding force to the outer surface of water pump circulation pipe in process simultaneously, and work as the moment of the stressed change of interior reamer, also chatter mark can not be produced at the outer surface of water pump circulation pipe, thus significantly reduce the mismachining tolerance of water pump circulation pipe outer surface, improve the machining accuracy of water pump circulation pipe outer surface.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As depicted in figs. 1 and 2, this interior reamer, comprises the cylinder handle of a knife 3 of some blades 1 and a hollow; The inner surface of described cylinder handle of a knife 3 is equally spaced is provided with several for installing the blade installation slot of blade 1, and the outer surface of cylinder handle of a knife 3 is provided with screw reactor pit 2; Described blade 1 by being fixedly connected with integral blade body 11 and blade 12 forms; Described blade 12 is in prismatic, and blade 12 two ends opposing blades body 11 is provided with chamfering; The lower edges place of described cylinder handle of a knife 3 is provided with chamfering; The outer surface of cylinder handle of a knife 3 is also provided with a V-type groove 4.
As shown in Figure 3, use before interior reamer processes water pump circulation pipe, first reamer bolt in shaping is arranged on the end of the adapter sleeve 5 be connected with drill press spindle, water pump 7 is arranged on the positioning tool 6 of T-shape by alignment pin;
Interior reamer is used to add man-hour to the circulation pipe 71 on water pump 7,
The first step, determines the center line of the circulation pipe 71 on water pump 7 and the center line alignment of interior reamer;
Second step, then in reamer with 200r/min ~ 300r/min rotate while with the speed feed of 30mm/min;
3rd step, starts at the uniform velocity withdrawing after the axial processing length of water pump circulation pipe reaches 30mm ~ 70mm;
When using interior reamer to process water pump circulation pipe, the machining accuracy of circulation pipe outer surface is-0.1mm ~ 0.1mm, and roughness is Ra6.3.
Wherein the allowance of the rotating speed of interior reamer, feed velocity, circulation pipe 71 and roughness are all summed up by repetition test and draw.
