Abstract
The invention discloses a device and a method for processing a honing open pore, belonging to a honing processing technology of key characteristic elements of parts. The processing device consists of a filling and positioning barrel and a fastening screw, wherein an inner bore on the filling and positioning barrel is in sliding fit and positioning with the excircle of a part; a section of convex arc on the filling and positioning barrel is used for repairing an open pore on the part to form a complete round hole and angularly position, so that mounting is achieved, i.e. self positioning; the fastening screw is used for fastening the filling and positioning barrel on the part to ensure that the processing of the open pore on the honing part is converted into the processing of a complete honing round pore; and after the honing reaches a processing index, the fastening screw is unscrewed to dismount the filling and positioning barrel from the part. Compared with the prior art, the honing processing has the advantages of continuous boundary and uniform stress and overcomes the defect of easy break off caused by discontinuous boundary of a honing rod in the honing processing.
Description
Technical field
The invention belongs to the process technology of product parts key feature key element, particularly the honing process technology of open pore.
Background technology
Some product parts is the critical component that cooperates, carries out start in the hydraulic system, requires part to have high toughness and wearability, and part material is 1Cr11Ni2W2MoV, Quenching Treatment after the case-carbonizing, and the machine cut performance reduces, and belongs to difficult processing parts.And the open pore manufacturing procedure is the Precision Machining that part is finally finished, and need guarantee the dimensional accuracy and the roughness requirement in this hole by honing open pore.But because honing stone is unsteady, in the process of honing open pore, honing stone rotates easy clamping stagnation in open pore, produce the honing chip breaking, because open pore processing border is discontinuous, cause honing lever to beat, fracture easily simultaneously, crudy is difficult to guarantee the processing cost height.Therefore study open pore honing technique method, design and produce very necessity of the special-purpose grinding equipment of open pore.
Summary of the invention
Purpose of the present invention: the isolated plant and the method that propose at the shortcoming that has honing lever frangibility in the part open pore honing processing now, realize the continuity of honing machining, avoid honing chip breaking processing and the honing lever that fractures guarantees the dimensional accuracy and the roughness requirement of open pore simultaneously.
Technical scheme of the present invention is: the processing unit (plant) that designs and produces a kind of honing open pore, positioning tube 1 and trip bolt 2 constitute by filling a vacancy, it is characterized in that: endoporus on the positioning tube 1 of filling a vacancy and the location of the cylindrical sliding fit on the part 3, one section protruding circular arc 5 of filling a vacancy on the positioning tube 1 cooperates with open pore 4 barbed portion on the part 3, and, realize installing promptly self-align to the positioning tube 1 angle location of filling a vacancy; Trip bolt 2 positioning tube 1 of will filling a vacancy is fastened on the part 3.
Described positioning tube endoporus and the part cylindrical sliding fit location of filling a vacancy, fit clearance is 0.01～0.04mm, satisfies the honing processing request, guarantees the easily installation of this device simultaneously.
For guarantee to fill a vacancy positioning tube 1 location endoporus precision and one section protruding circular arc 5 have wearability, fill a vacancy positioning tube endoporus 1 and one section protruding circular arc 5 are adopted the processing method of accurate line cutting, and the positioning tube 1 of filling a vacancy is carried out Quenching Treatment, make its HRC＞55.
A kind of method of honing open pore is provided simultaneously, it is characterized in that, comprise the steps:
1) will fill a vacancy positioning tube 1 assembles with part 3, with the open pore 4 on one section on the positioning tube 1 of the filling a vacancy protruding circular arc 5 repairing parts 3, make open pore 4 borders on the part 3 continuous, form complete circular hole 6, assembling back is fastened on the part 3 with trip bolt 2 positioning tube 1 of will filling a vacancy;
2) the complete circular hole 6 that forms is repaired in honing, reaches the processing index;
3) unscrew trip bolt 2, the positioning tube 1 of will filling a vacancy is pulled down from part 3, forms open pore 4.
Advantage of the present invention and beneficial effect: the technology of the present invention compared with prior art, honing processing border is continuous, stressed evenly, overcome the discontinuous shortcoming that causes honing lever frangibility in the honing processing in border.

Fig. 3 is the schematic diagram of processing unit (plant) of the present invention and part assembling.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further details:
As shown in Figure 3, a kind of processing unit (plant) of honing open pore, positioning tube 1 and trip bolt 2 constitute by filling a vacancy, it is characterized in that: endoporus on the positioning tube 1 of filling a vacancy and the location of the cylindrical sliding fit on the part 3, one section protruding circular arc 5 of filling a vacancy on the positioning tube 1 cooperates with open pore 4 barbed portion on the part 3, and, realize installing promptly self-align to the positioning tube 1 angle location of filling a vacancy; Trip bolt 2 positioning tube 1 of will filling a vacancy is fastened on the part 3.
As depicted in figs. 1 and 2, positioning tube endoporus and the part cylindrical sliding fit location of filling a vacancy, fit clearance is 0.01～0.04mm, satisfies the honing processing request, guarantees the easily installation of this device simultaneously.
One section open pore 4 that protruding circular arc 5 is repaired on the part 3 on the described positioning tube 1 of filling a vacancy, and be used for preventing that angular motion from making the circular arc dislocation of repairing opening, and realizing installing promptly self-align in the angle location.
Described trip bolt 2 positioning tube 1 of will filling a vacancy is fastened on the part 3, guarantees the part 3 and the positioning tube 1 no play of filling a vacancy in the honing processing.
For guarantee to fill a vacancy positioning tube 1 location endoporus precision and one section protruding circular arc 5 have wearability, fill a vacancy positioning tube endoporus and the one section projection circular arc 5 of filling a vacancy is adopted the processing method of accurate line cutting, and the positioning tube 1 of filling a vacancy is carried out Quenching Treatment, make its HRC＞55.
A kind of method of honing open pore is characterized in that, comprises the steps:
