Description
Technical field
The utility model relates to bent axle mill connecting rod neck pre-determined bit servicing unit, specifically a kind of bent axle mill connecting rod neck degree of presorting positioner.
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, also do not see the device that is used for bent axle mill connecting rod neck degree of presorting location on the market.
Summary of the invention
The utility model technical problem to be solved is the deficiency that overcomes above-mentioned prior art, provides a kind of rational in infrastructure, makes simply, and is easy for operation, bent axle mill connecting rod neck degree of the presorting positioner that the calibration location efficiency is high.
The technical scheme that the utility model solves the problems of the technologies described above employing is: a kind of bent axle mill connecting rod neck degree of presorting positioner; It is characterized in that: it is provided with bent axle supporting and positioning mechanism and degree of presorting detent mechanism; Supporting and positioning mechanism comprises supporter and is installed in V-arrangement back-up block, the positioning seat 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, and level connects the circumferential reference column of a crank-shaft link neck on it, realizes that with this bent axle circumferentially locatees; Said degree of presorting 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, and the bottom is provided with degree of presorting locating slot, and the flange reference column is installed on the supporter; Top is provided with round pin and cooperates with degree of the presorting locating slot of ring flange; After ring flange was confirmed with respect to the circumferential position of bent axle, ring flange was fixed on the crankshaft big end end through 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 degree of presorting locating slot, just can clamp bent axle and carry out the rod journal grinding.
The said ring flange cylindrical of the utility model 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 circle wall of the utility model, cooperate with screw through housing screw, ring flange is fixed on the crankshaft big end end, forms one with bent axle.
The utility model adopts above-mentioned composition structure, carries out bent axle respectively and supports location and degree of presorting location.Against existing technologies, the utility model is rational in infrastructure, makes simply, and easy for operation, degree of presorting location efficiency is high, has reduced operator's labour intensity.It is applicable to fixture for grinding machine and cooperates calibration to clamp bent axle, on grinding machine, carries out the rod journal grinding.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further to describe.
Fig. 1 is the utility model assembly structure sketch map.
Fig. 2 is that the A of Fig. 1 is to structural representation.
Fig. 3 is that the B of Fig. 1 is to structural representation.
1. bolts among the figure, 2. flange reference column, 3. ring flange, 4. bent axle, 5. V-arrangement back-up block, 6. supporter, 7. positioning seat, 8. circumferentially reference column, 9. degree of presorting locating slot, 10. housing screw.
The specific embodiment
From Fig. 1, Fig. 2, Fig. 3, can find out; A kind of bent axle mill connecting rod neck degree of presorting positioner; It is provided with bent axle supporting and positioning mechanism and degree of presorting detent mechanism; Supporting and positioning mechanism comprises that supporter 6 is all fixing with bolt 1 with positioning seat 7 with 7, two the V-arrangement back-up blocks of V-arrangement back-up block 5, positioning seat 5 that are installed on the supporter 6.Two V-arrangement back-up blocks 5 are supported under the bent axle 4 two ends trunnions; Positioning seat 7 is supported on bent axle 4 one connecting rod neck sides; Level connects the circumferential reference column 8 of a crank-shaft link neck on it; Circumferentially reference column 8 one ends are fixed on the positioning seat 7 with screw thread, and other end location bent axle 4 connecting rod necks have been realized the circumferential location of bent axle 4 with this.Like Fig. 1, shown in Figure 3.
Said degree of presorting detent mechanism includes a ring flange 3, flange reference column 2, and ring flange 3 is provided with the centre bore that cooperates with the crankshaft big end cylindrical, and the bottom is provided with degree of presorting locating slot 9.Flange reference column 2 is installed on the supporter 6.Flange reference column 2 bottoms are fixing with bolt 1; Top is provided with round pin and cooperates with degree of the presorting locating slot 9 of ring flange 3; Like Fig. 1, shown in Figure 2. confirm the circumferential position of ring flange 3 with respect to bent axle 4 with this, after ring flange 3 was confirmed with respect to the circumferential position of bent axle 4, ring flange 3 was fixed on the crankshaft big end end through housing screw 10; Make bent axle 4 and ring flange 3 form one, realized degree of the presorting location of bent axle.The bent axle 4 that then will form one hangs in fixture for grinding machine with ring flange 3, and the circumferential alignment pin of chucking operation cooperates the location with degree of presorting locating slot 9, just can clamp bent axle and carry out the rod journal grinding.At this moment, degree of presorting locating slot 9 just plays the crankshaft end-face locating hole, is convenient to cooperate the calibration location with fixture for grinding machine, carries out the rod journal grinding.
