Description
Technical field
The utility model belongs to water pump and manufactures field, the special fixture of particularly a kind of mixed-flow pump keyseat processing.
Background technology
After mixed-flow pump impeller shaft coupling machines, need in taper hole to carry out keyseat processing, current keyway design is generally straight trough design, the keyway of parallel taper hole bus is designed to after improvement, ensure that the keyway two ends degree of depth is consistent, improve linking intensity and the service life of pump shaft and impeller shaft coupling, but be the increase in difficulty of processing, common clamping cannot complete processing.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of keyseat fixture with general applicability, accurately location, quick-clamping impeller shaft coupling.
For solving the problems of the technologies described above, the utility model provides a kind of water pump vane shaft coupling fixture for slotting machine, comprise base plate, locating piece, silk ear, mandrel, sinusoidal cushion block, holder, bolt assembly, the front of base plate is provided with seam, the back side of base plate is welded with 4 mandrel locating pieces, 2 is one group, locating piece is provided with U-type groove position, two mandrels are arranged in locating piece U-type groove position, 4 silk ears are welded on the centre position on four limits at the base plate back side, silk ear is connected with holder by bolt assembly, holder is fixed on slotting machine workbench, sinusoidal cushion block is by padded for a mandrel.
Described mandrel two ends are provided with a hole, and mandrel is by bolt assembly and locating piece axial locking.
After fixture is roughly located on the table, impeller shaft coupling loads base plate by positioning spigot, directly obtains required setting angle.Just can process after workpiece centering fastens.
Setting angle required when adopting the impeller shaft coupling fixture for slotting machine of technique scheme can obtain slotting fast, the thickness of sinusoidal cushion block can design according to the hole taper of workpiece, to realize the setting angle of different tapering workpiece, there is applicability widely, mandrel and sinusoidal cushion block all adopt modified and grinding process, ensure that precision and the serviceability of clamp part.
Accompanying drawing explanation
Fig. 1 is utility model works view.
Fig. 2 be in Fig. 1 B to schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of impeller shaft coupling fixture for slotting machine, comprises base plate 1, locating piece 2, silk ear 3, mandrel 4, M12 bolt assembly 5, sinusoidal cushion block 6, holder 7, M16 bolt assembly 8.The back side of base plate 1 is welded with 4 locating pieces 2 and 4 silk ear 3(as shown in Figure 2).Locating piece 2 is provided with U-type groove position, U-type groove position processes at one time, the strict guarantee tolerance of groove width and slot pitch.Mandrel 4 two ends are provided with a hole, and two mandrels 4 to load behind locating piece slot by M12 bolt assembly 5 and locating piece 2 axial locking, are integrated with base plate 1 one-tenth.4 silk ears 3 are welded on the centre position on four limits at base plate 1 back side, and silk ear 3 is connected with holder 7 by M16 bolt assembly 8, and holder 7 is fixed on slotting machine workbench, and sinusoidal cushion block 6 is by padded for a mandrel.Impeller shaft coupling 9 loads base plate 1 by positioning spigot.
If two mandrel distances are L, impeller shaft coupling hole taper is A, and required setting angle is β, and sinusoidal cushion block height is H.Wherein L and A is known, then have: β=arctanA/2, H=L × sin β.If get A=1:10=0.1, L=320, then β=arctan0.05=2.86 o, H=320 × sin2.86 o=15.97.The thickness of sinusoidal cushion block can design according to the hole taper of workpiece, with the setting angle requirement of satisfied different tapering workpiece.Sinusoidal cushion block obtains required setting angle after padded for a mandrel, and impeller shaft coupling loads base plate by positioning spigot, just can process after workpiece centering fastens.
Setting angle required when adopting the impeller shaft coupling fixture for slotting machine of technique scheme can obtain slotting fast, the thickness of sinusoidal cushion block can design according to the hole taper of workpiece, to realize the setting angle of different tapering workpiece, there is applicability widely, mandrel and sinusoidal cushion block all adopt modified and grinding process, ensure that precision and the serviceability of clamp part.
Personnel in the art should be realized that; above-described embodiment is not used as restriction of the present utility model; as long as in spirit of the present utility model, any protection domain of the present utility model is not all exceeded to above-described embodiment technique variation, flexible program.
