Description
Technical field
The utility model relates to a kind of bushing plate device, specifically a kind of brill crankshaft flange end-face hole plate device.
Background technology
We know, at present, the crankshaft flange end face all needs the auger shell hole, and are most on the big end surface of bent axle, and the distributed dimension in hole, quantity are variant.Common process stipulation subdrilling locating hole, auger shell hole bottom outlet is attacked screw with screw tap then again.Finish these processing and need join a cover boring grab at radial drilling machine.The crankshaft flange end face faces up, and vertically is clamped in the anchor clamps, and bushing plate is provided with the spring clamping flange dish outer round surface that rises.But under the less situation of ring flange outer round surface area, this device can not clamp template, causes skew of auger shell hole site or boring to be scrapped.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of rational in infrastructure, makes simply, and is easy to operate, determines the brill crankshaft flange end-face hole plate device that the bore position precision is high.
The technical scheme in the invention for solving the above technical problem is: a kind of brill crankshaft flange end-face hole plate device, it is provided with a template, fixed installation one alignment pin and some drill bushings on the template, template is positioned on the crankshaft flange end face, alignment pin inserts in the ring flange end face locating hole, it is characterized in that: described template center is provided with a ladder through hole, the spring that rises is installed in the through hole, pull bar, the ringfeder of spring lower end for the band inner conical surface rises, ringfeder inserts in the ring flange end face dead eye, pull bar passes the spring that rises, and its upper end cooperates with a nut, and the lower end is provided with the projection of the band conical surface, the projection of the pull bar band conical surface is identical with the ringfeder of the spring band inner conical surface that rises, torque nut drives pull bar and moves up, and the ringfeder tensioner fixes template in the dead eye inwall.
The utility model is said to rise by spring and pull rod shaft to linking to each other by a bearing pin.
Go back suit one spring on the said pull bar of the utility model, the spring upper end contacts with a flange of the spring inwall that rises, and the spring lower end contacts with the projection of the pull bar band conical surface.Spring makes pull bar and the spring that rises is subjected to the effect of a downward force, is in downward elongation state.
Be axially arranged with the strip opening on the ringfeder of the said spring lower end band inner conical surface that rises of the utility model.
The utility model adopts above-mentioned composition structure, by the spring that rises that inserts in the crankshaft flange end face dead eye template and crankshaft flange clamping is fixed, and then holes in crankshaft flange end face relevant position.Against existing technologies, the utility model is rational in infrastructure, and is easy for operation, determines bore position precision height, is applicable to the processing of crankshaft flange end-face hole.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model assembly structure schematic diagram.
Fig. 2 is the schematic top plan view of Fig. 1.
Number in the figure is: 1. alignment pin, 2. template, 3. nut, 4. bearing pin, 5. pull bar, the spring that 6. rises, 7. spring, 8. drill bushing, 9. crankshaft flange end face.
The specific embodiment
Fig. 1 is the utility model assembly structure schematic diagram, also is clamping stationary state schematic diagram.
From Fig. 1, Fig. 2 as can be seen, a kind of brill crankshaft flange end-face hole plate device, it is provided with a template 2, fixed installation one alignment pin 1 and some drill bushings 8 on the template 2, template 2 is positioned on the crankshaft flange end face 9, and alignment pin 1 inserts in ring flange end face 9 locating holes, as the location.
Template described in the utility model 2 centers are provided with a ladder through hole, and the spring 6 that rises, pull bar 5 are installed in the ladder hole.The spring 6 that rises is sleeved on pull bar 5 outsides, spring 6 middle parts of rising are stuck on the boss of template 2 ladder holes, the ringfeder of spring 6 lower ends for the band inner conical surface rises, ringfeder inserts in the ring flange end face dead eye, pull bar 5 passes the spring 6 that rises, its upper end cooperates with a nut 3, the lower end is provided with the projection of the band conical surface, the projection of the pull bar 5 band conical surfaces is identical with the ringfeder of the spring 6 band inner conical surfaces that rise, torque nut 3 drives pull bar 5 and moves up, the stressed generation distortion of the ringfeder of the spring 6 lower end band inner conical surfaces that rise, its outwardly-bent opening, tensioner fixes the relative ring flange end face of template clamping in ring flange end face dead eye inwall.
The said spring 6 that rises of the utility model axially links to each other by a bearing pin 4 with pull bar 5.Bearing pin 4 has limited the rotation of pull bar 5.Like this, pull bar 5 can only move vertically relative to the spring 6 that rises, and can not rotate.
Go back suit one spring 7 on the said pull bar 5 of the utility model, spring 7 upper ends contact with a flange of spring 6 inwalls that rise, and spring 7 lower ends contact with the projection of the pull bar 5 band conical surfaces.Spring 7 makes pull bar 5 and the spring 6 that rises is subjected to the effect of a downward force all the time like this, is in downward elongation state, makes things convenient for the flexible of pull bar.。
Be axially arranged with the strip opening on the ringfeder of the said spring 6 lower end band inner conical surfaces that rise of the utility model.Like this, be convenient to ringfeder tapering spreading.
When the utility model uses, be example, with crankshaft big end up, vertically be clamped in the anchor clamps with four cylinder crankshafts.Adjust nut 3 and make rise spring 6 and pull bar 5 be in the noncontact stress, rising does not stress between spring 6 and the pull bar 5.Then template 2 is positioned over the ring flange end face, alignment pin 1 is aimed at crankshaft flange end face locating hole, the spring 6 that rises is aimed at crankshaft flange end face dead eye, reverse clamp nut 3, nut 3 drives pull bar 5 and moves up, the stressed generation distortion of the ringfeder of the spring 6 lower end band inner conical surfaces that rise, its outwardly-bent opening, tensioner fixes the relative ring flange end face of template clamping in ring flange end face dead eye inwall.But at this moment just work bit along drill bushing 8 pilot holes.
