Description
Technical field
The utility model relates to a kind of lathe clamp for machining, particularly a kind of special fixture of water pump vane base calibration Boring.
Background technology
After axial-flow pump impeller seat axis hole processes, repeatedly Boring need to be carried out in side.Current impeller base calibration generally adopts index dial to carry out calibration, but, because axial-flow pump impeller seat appearance and size is larger, weight reaches the 2-3 ton, and the plain indexing dish can't carry out calibration.Therefore, develop a kind of special fixture of water pump vane base calibration Boring necessary.
Summary of the invention
The purpose of this utility model is to provide a kind of calibration boring jig with general applicability, accurate calibration, quick-clamping impeller base.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of water pump vane base calibration boring jig, comprise a base plate, the base plate two ends respectively are equipped with a bearing body, the bearing body upper end is provided with bearing cap, between the endoporus of two bearing bodies and bearing cap, main shaft is installed, bearing cap is connected with bolt assembly with bearing body and compresses main shaft, and main shaft is provided with fixed dam and location-plate I and location-plate II and round nut, and index dial is connected with main shaft by flat key, and connecting locking with main shaft by screw, the calibration screw is fixed on bracing frame.
Preferably, be provided with the one division groove every 30 degree or 60 degree on index dial.
Adopt the impeller base boring jig of technique scheme to carry out calibration and clamping workpiece to workpiece very easily, and can design one to the indexing trough of index dial every 30 degree or 60 degree as required, to realize the calibration requirement of the different angles such as different impeller base 90 degree, 120 degree, there is versatility.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the utility model provides a kind of water pump vane base calibration boring jig, comprises base plate 1, is arranged on two bearing bodies on base plate 2, two bearing caps 3, bracing frame 14, index dial 10, calibration screw 13 and main shaft portion.Main shaft portion comprises main shaft 4, is arranged on fixed dam 8, location-plate I 7, location-plate II 6, round nut 5 on main shaft 4, and index dial 10 is connected with main shaft 4 by flat key 11, and index dial 10 use screws 12 connect locking with main shaft 4.Calibration screw 13 is fixed on bracing frame 14.
Two bearing bodies and bearing cap once close boring and machine, and have guaranteed concentricity, and fixed dam 8 is interference fit with main shaft 4, during assembling, adopt hot charging to squeeze into main shaft 4.Can design one to the indexing trough of index dial every 30 degree or 60 degree as required, to realize the calibration requirement of the different angles such as different impeller base 90 degree, 120 degree.
During use, calibration screw 13 aligns with index dial groove position, tightens calibration screw 13 and withstands indexing trough.Impeller base is packed into after main shaft 4, and bearing cap 3 is connected with bearing body 2 use bolt assemblies 9, compresses main shaft 4, impeller base is arranged between the location-plate II 6 and location-plate I 7 on main shaft 4, realize impeller base axial location, utilize round nut 5 locking, thus fixing impeller base.After one time bore hole completes, bearing body 2 and bearing cap 3 are unclamped, exit calibration screw 13, rotation-indexing table, after rotating required angle, calibration screw 13 is screwed into to index dial 10 groove positions, realizes accurate calibration, bearing cap 3 is connected compression main shaft 4 with bearing body 2 use bolt assemblies 9, then carry out Boring again.
