Description
Technical field
The present invention relates to bent axle mill connecting rod neck pre-determined bit servicing unit, the pre-calibration positioner of specifically a kind of bent axle mill connecting rod neck.
Background technology
We know that grinding crank-shaft link neck on the existing grinding machine all is provided with a circumferential alignment pin on its anchor clamps, and this pin cooperates with crankshaft flange end face locating hole, realize grinding the calibration location of connecting rod neck.But some bent axle is owing to the restriction of structure, and end face of flange does not have locating hole, like this, just is not easy to carry out the calibration grinding of crank-shaft link neck.At present, yet there are no the device that is used for the pre-calibration of bent axle mill connecting rod neck location on the market.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, makes simply, and is easy for operation, the pre-calibration positioner of bent axle mill connecting rod neck that the calibration location efficiency is high.
The technical scheme that the present invention solves the problems of the technologies described above employing is: the pre-calibration positioner of a kind of bent axle mill connecting rod neck, it is characterized in that: it is provided with bent axle supporting and positioning mechanism and pre-calibration detent mechanism, supporting and positioning mechanism comprises supporter and the V-arrangement back-up block, the positioning seat that are installed on the supporter, two V-arrangement back-up blocks are supported under the crankshaft two end trunnion, positioning seat is supported on bent axle one connecting rod neck side, level connects the circumferential reference column of a crank-shaft link neck on it, realizes that with this bent axle circumferentially locatees; Described pre-calibration detent mechanism includes a ring flange, flange reference column, ring flange is provided with the centre bore that cooperates with the crankshaft big end cylindrical, the bottom is provided with pre-calibration locating slot, the flange reference column is installed on the supporter, top is provided with round pin and cooperates with the pre-calibration locating slot of ring flange, after ring flange was determined with respect to the circumferential position of bent axle, ring flange was fixed on the crankshaft big end end by housing screw, forms one with bent axle.Bent axle and the ring flange that then will form one hang in fixture for grinding machine, and the circumferential alignment pin of chucking operation cooperates the location with pre-calibration locating slot, just can clamp bent axle and carry out the rod journal grinding.
Ring flange cylindrical of the present invention is stepped, and centre bore also is stepped.Be used for cooperating and clamp bent axle and ring flange with fixture for grinding machine.
Radially evenly be provided with screw on the said ring flange circumferential wall of the present invention, cooperate with screw by housing screw, ring flange is fixed on the crankshaft big end end, forms one with bent axle.
The present invention adopts above-mentioned composition structure, carries out bent axle respectively and supports location and pre-calibration location.Against existing technologies, the present invention is rational in infrastructure, makes simply, and is easy for operation, and pre-calibration location efficiency height has reduced operator's labour intensity.It is applicable to fixture for grinding machine and cooperates calibration to clamp bent axle, carry out the rod journal grinding on grinding machine.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is an assembly structure schematic diagram of the present invention.
