Abstract
The utility model provides a universal composite tensioning tool for grinding a blade. The universal composite tensioning tool is characterized by mainly comprising a support frame, an eccentric shaft, a slide block and a puller bolt, wherein the appearance of the support frame facilitates the installation of the support frame in a required place; a slide block limiting groove is arranged at the centre position; penetrating holes of the neck of the eccentric shaft can be inserted on two sides of the groove; the aperture of the penetrating hole on one side is greater than or equal to the diameter of the smallest circle including the section of the eccentric shaft; a thread through hole is arranged in the side of the hole; an elliptical hole penetrating through the eccentric shaft is arranged in the slide block; the short diameter of the elliptical hole is in a sliding direction and is equal to the diameter of an eccentric part of the eccentric shaft; the long diameter of the elliptical hole is equal to the total swinging length of the eccentric part of the eccentric shaft; and the slide block is put into a slide block limiting groove of the support frame, and the eccentric shaft is inserted into the support frame and passes through the slide block to resist against the eccentric shaft from the thread through hole of the support frame by the puller bolt. The universal composite tensioning tool for grinding the blade provided by the utility model has the advantages that the structure is simple, and the contact surface with the blade is more than 80%; and the locating accuracy is ensured and the generality is strong.
Description
Technical field
The present invention relates to be used for the omnipotent compound tool that rises of blade grinding.
Background technology
A new generation's aeroengine rotor assembly structure be different from fully one, two generation engine, grinding is also had higher requirement to the rotor blade blade tip.The circumferential assembly structure mode of the high-pressure compressor rotor blade of new construction and drum barrel causes blade and tongue-and-groove gap bigger, processes under the maintenance extended state for making the blade external diameter, and be the target that guarantees that blade outside dimension tolerance and circular runout are pursued.For many years; The processing of rotor blade external diameter takes every blade to be installed on the mimic panel, with screw jack-up blade one by one; Use the common transformation of the way equipment low speed mimic panels at different levels to be carried out the process of grinding; Not only production efficiency is low and easy that the blade top is oblique, and quality state cloth is stable, can't meet design requirement.
Present stage development model is many especially, and state of the art changes greatly, and what each model has coil, every grating mimic panel, the technological preparation cycle is long, the production cost height, in case and wheel disc, blade dimensions change, mimic panel will use, and causes very big waste.
Summary of the invention
The object of the present invention is to provide a kind of can be with the general utility tool of blade tensioner.
The present invention provides a kind of omnipotent compound tool that rises that is used for the blade grinding, it is characterized in that: mainly comprise frame, eccentric shaft, a slide block and hold out against screw, the profile of a frame is convenient to be installed to required place; Centre bit is equipped with the slide block stopper slot; The through hole of eccentric shaft axle journal can be assigned in the groove both sides, and wherein the aperture of a side is more than or equal to the minimum diameter of a circle that comprises the eccentric shaft cross section, and there is tapped through hole this side, hole; The elliptical aperture of wearing eccentric shaft is arranged in the slide block; Its short diameter equals the diameter of eccentric shaft eccentric part on glide direction, long diameter equals the swing total length of eccentric shaft eccentric part; Slide block is put in the slide block stopper slot of a frame, and eccentric shaft inserts a frame and passes slide block, withstands eccentric shaft with holding out against the tapped through hole of screw from a frame.
During use, this instrument is inserted respectively on the mimic panel under each blade, rotation eccentric axis, eccentric shaft are released slide block under the restriction that holds out against screw, the tensioner blade.
The omnipotent compound tool that rises that is used for the blade grinding provided by the invention, an end of its eccentric shaft can have spiral shell cutter groove, so that use the screwdriver rotation eccentric axis.
The omnipotent compound tool that rises that is used for the blade grinding provided by the invention, its eccentric shaft are stayed on the outer axle journal of a frame can have the plane, so that use the spanner rotation eccentric axis.
The omnipotent compound tool that rises that is used for the blade grinding provided by the invention, the external square head of the axle journal of its eccentric shaft is so that use the box spanner rotation eccentric axis.
The omnipotent compound tool that rises that is used for the blade grinding provided by the invention, its advantage is: simple in structure, with the contact-making surface of blade more than 80%, guarantee accurate positioning, highly versatile.
Description of drawings
Fig. 1 is the structural representation that is used for the omnipotent compound tool that rises of blade grinding;
Fig. 2 is the A-A profile that is used for the omnipotent compound tool that rises of blade grinding;
Fig. 3 is the omnipotent compound tool user mode on mimic panel that rises of blade grinding.
The specific embodiment
Be used for the omnipotent compound tool that rises of blade grinding, its structure is as shown in Figure 1, comprises frame 1, eccentric shaft 2, a slide block 3 and holds out against screw 4; The profile of propping up frame 1 is convenient to be installed to required place, and centre bit is equipped with the slide block stopper slot, and the through hole of eccentric shaft 2 axle journals can be assigned in the groove both sides; Wherein the aperture of a side is more than or equal to the minimum diameter of a circle that comprises eccentric shaft 2 cross sections, and there is tapped through hole this side, hole, the external square head of the axle journal of eccentric shaft 2; The elliptical aperture of wearing eccentric shaft 2 is arranged in the slide block 3; Its short diameter equals the diameter of eccentric shaft 2 eccentric parts on glide direction, long diameter equals the swing total length of eccentric shaft 2 eccentric parts; Slide block 3 is put in the slide block stopper slot of a frame, and eccentric shaft 2 inserts a frame 1 and passes slide block 3, withstands eccentric shaft 2 with holding out against the tapped through hole of screw 4 from a frame 1.
During use; This instrument is inserted on the mimic panel 5 each blade respectively 6 times; With the square head of box spanner through backboard 9 rotation eccentric axis 2, eccentric shaft 2 is released slide block 3 under the restriction that holds out against screw 4, and tensioner is with the blade 6 of front apron 8 with the band damping fin 7 of backboard 9 location.
