Abstract
A pin presser is characterized in that a positioning tenon is arranged on the lower surface of a positioning block and corresponds to a mortise on a workpiece in position, centers of a screw mounting hole and a pressure pin mounting hole are arranged in a center line of the positioning block are arranged on the positioning block, the positioning block 4 is mounted on the workpiece through the tenon, and a 0.5-1mm gap is reserved between the lower surface of the positioning block 4 and the upper surface of the workpiece. The positioning block of the pin presser is tightly attached to two sides of the mortise by the aid of tenon-mortise positioning of the workpiece, and positioning precision of the pin presser is guaranteed. The pin presser avoids deflection when the pressure pin is stressed, the pressure pin is attached to the upper surface of the positioning block under knocking so that hurt to the outer surface of the mortise of a turbine disc is avoided, assembly requirements of parts are met reliably by using the pin presser, and assembly efficiency is increased from original 20% to over 95%.
Description
Technical field
The present invention is a kind of instrument that is used for engine, gas turbine turbine disk assembly pad.
Background technology
When compressor rotor turbine disk assembly pad assembles, the pin upper surface that technological requirement is pressed into gos deep into turbine disk tongue-and-groove bottom land distance and is 0.1mm～0.2mm, existing technical scheme as shown in Figure 1, its pad instrument only is a simple pin, when adopting this instrument to carry out the pin assembling, because pad lacks correct guiding and spacing, workman's execute-in-place very easily causes turbine disk tongue-and-groove surface to injure by a crashing object, the pin degree of depth that is pressed into can't be controlled, is difficult to meet process specification requirements.Above factor is perplexing the assembling process of certain machine High Pressure Turbine Rotor always, is that one of difficult problem that solves is badly in need of in the production scene.
Summary of the invention
Injure by a crashing object for overcoming the turbine disk tongue-and-groove surface of easily causing that exists in the prior art, the deficiency that the pin degree of depth that is pressed into can't be controlled the present invention proposes a kind of pad device.
Turbine disk assembly pad of the present invention comprises locating piece, screw, pad and handle with instrument.Locating piece is a diamond block, and this locating piece lower surface has a location tenon, and the position of this location tenon is corresponding with the workpiece upper tenon groove.The installing hole that screw and pad are arranged on locating piece, and the hole heart of screw mounting hole and pad installing hole is positioned on the center line of this locating piece.Locating piece is installed on the workpiece by tenon, and the gap of 0.5～1mm is arranged between the lower surface of locating piece and the workpiece surface.The installing hole that pad passes on the locating piece is installed on the workpiece, and pin is installed in the end of pad.Screw is installed in the screwed hole on the locating piece, and handle is installed in the handle hole of screw termination.
The bullport of pad is in a side of locating piece location tenon, and the bullport of screw connects the location tenon of locating piece.
Described location tenon is trapezoidal, its both side surface all and the angle between locating piece 4 center lines be 20 °, and round-corner transition between both side surface and the end face.
The present invention makes the locating piece of pad device fit tightly the tongue-and-groove two sides by the tongue-and-groove location of workpiece, makes the positioning accuracy of this pad device obtain reliable assurance.Deflection takes place with the guiding of the bullport on the locating piece in pad when avoiding pad stressed, by knocking pad, the step surface of pad and the upper surface of locating piece are fitted, and the pin that then is pressed into arrives the process stipulation size.The present invention has overcome existing deficiency in the prior art, has avoided injuring by a crashing object of turbine disk tongue-and-groove outer surface, uses this pad instrument to make the matching requirements of part obtain reliable assurance, and efficiency of assembling is brought up to more than 95% by original 2 0%.

The specific embodiment
Present embodiment comprises pad 1, pin 2, workpiece 3, locating piece 4, screw 5 and handle 6.Locating piece 4 is a diamond block, along these locating piece 4 length directions location tenon 7 is arranged at locating piece 4 lower surfaces, and the position of this location tenon 7 is corresponding with workpiece 3 upper tenon grooves; The bullport that screw 5 and pad 1 are arranged on locating piece 4, and the hole heart of screw bullport and pad bullport is positioned on the center line of this locating piece; Locating piece 4 is installed on the workpiece 3 by tenon 7, and the gap of 0.5～1mm is arranged between the lower surface of locating piece 4 and workpiece 3 upper surfaces; The bullport that pad 1 passes on the locating piece 4 is installed on the workpiece 3, and pin 2 is installed in the end of pad 1; Screw 5 is installed in the screwed hole on the locating piece 4, and handle 6 is installed in the handle hole of screw 5 terminations.
The mounting hole site of described screw 5 is in tenon 7 middle parts, the location of locating piece 4; The pad mounting hole site is in a side of location tenon.
Described location tenon 7 is trapezoidal, its both side surface all and the angle between locating piece 4 center lines be 20 °, and round-corner transition between both side surface and the end face.
During use, locating piece 4 fits tightly by the tongue-and-groove two sides of handle 6 with workpiece 3, by moving axially of pin 2 restriction workpiece 3.Pad 1 is guiding with the hole on the locating piece 4.When knocking pad 1 its step surface and locating piece 4 upper surfaces being fitted, the pin 2 that be pressed into arrives the correct assembling degree of depth, makes the upper surface of the pin 2 that requirement is pressed into go deep into the tongue-and-groove bottom land of workpiece 3.
