Background technique
Impeller press-assembling is generally in the end in the one procedure in the water pump complement, the impeller relative component is less, generally is assembly is placed on the worktable, and impeller is placed on the pressure head, pressure head contact impeller presses down, easy to operate, but when impeller is pressed into pump shaft, in placement, tilt easily, press-fit process along with placement direction tilts, usually pull the fitting surface of hole axle, the hole cooperates formation point or line to contact with axle when being press-fit into place, formation face contact.And this structure needs the impeller of identical shaped different-diameter to need the pressure head of design specialized, and belt pulley shape difference also need be made different bases, and fabricating cost is higher.Annual manufacturing cost is up to 100,000 yuan, and it is inconvenient to change product, influences efficient.
Summary of the invention
For solving the above-mentioned defective that prior art exists, the object of the present invention is to provide a kind of compact structure, easy to operate, impeller and pump shaft are accurately assembled, the manufacturing efficiency height has been saved the water pump vane press-loading apparatus of anchor clamps manufacturing costs.
Another object of the present invention also provides a kind of water pump vane pressing method.
For achieving the above object, the technical solution used in the present invention is: this a kind of water pump vane press-loading apparatus, has dunnage, it is characterized in that: described dunnage is provided with four directional posts, the outer cover of each directional post is equipped with supported spring, be set with positioning plate on the directional post, supported spring is between dunnage and positioning plate, the central position of described dunnage is fixed with positioning block, the center of positioning block is provided with elasticity impeller alignment axis mechanism, the positioning plate central position is provided with the through hole that impeller can pass, positioning plate is provided with two locating studs, water pump component is provided with the positioning hole that cooperates with locating stud, locating stud and positioning hole cooperate and the end face of water pump component with top cooperation of positioning plate form the plane and two pits location, make the center of water pump component concentric with elasticity impeller alignment axis mechanism.
Described elasticity impeller alignment axis mechanism has the impeller alignment axis, the impeller alignment axis is positioned at the step hole at positioning block and dunnage center and stretches out positioning block, the step hole that is arranged in the positioning block part is set with the lining that the impeller alignment axis is play the guiding role, be provided with pressure spring in the step hole, pressure spring supports the impeller alignment axis, clamping bolt is by the countersunk head center hole locking impeller alignment axis of impeller alignment axis, and the impeller alignment axis can move up and down along lining.
One of described two locating stud are the cylinder locating stud, and one is the rhombus locating stud.
The pressing method of water pump vane press-loading apparatus is characterized in that following these steps to operation: (1), at first the big face with water pump vane is placed on the positioning block 11, and the water pump vane center hole is sleeved on the impeller alignment axis 12 that is positioned at the positioning block central position; (2), with water pump component with the plane and two pits location and installation on positioning plate 5; (3), the breakout pressure machine, pressure head 1 is pushed down the rotating shaft of water pump component, and is descending under the effect of press machine, the rotating shaft of water pump component is pressed in the impeller bore gradually, when equipment put in place in program, impeller was also finished and is press-fited.
Adopt the beneficial effect of technique scheme: the dunnage central position of water pump vane press-loading apparatus is fixed with positioning block, the center of positioning block is provided with elasticity alignment axis mechanism, when being placed on impeller on the positioning block, elasticity alignment axis mechanism can be fixing in the horizontal direction with impeller.Water pump component is placed on the positioning plate, by the end face of water pump component and two locating studs (plane and two pits) location to the substantially horizontal of water pump component on positioning plate, because the center of the water pump component of positioning plate location and the centres of impeller alignment axis mechanism, pressure head presses down in the process of water pump component under the guiding of four directional posts of dunnage, remain the dead in line of the rotating shaft core and the impeller center hole of water pump component, when the rotating shaft of water pump component is pressed into the impeller center hole, the alignment axis of elasticity alignment axis mechanism moves down the center hole that withdraws from impeller, thereby impeller is pressed in the rotating shaft of water pump component.This water pump vane press-loading apparatus compact structure, clamping workpiece is convenient, whole press-fit need not artificial support in the process, and remain the dead in line of water pump component shaft axis and impeller center hole, press-fiting the back rotating shaft is that face contacts with impeller, and the impeller of different-diameter and the belt pulley of different-diameter can shared sleeve clamps, change product and need not change anchor clamps, improve manufacturing efficiency greatly, saved the anchor clamps manufacturing cost.
