Compared with the prior art, the measuring fixture has the advantages of accurate and reliable positioning and convenient adjustment.
Description
Technical field
The utility model is a kind of measured material of hot investment casting turbo blade, belongs to the technical field of structures of product, is used for the aeromotor manufacturing.
Background technology
Along with the raising of hot investment casting turbo blade manufacturing accuracy, and new requirement has been proposed detection technique.Reasonable this problem that solved of the laser non-contact measuring technology of newly-developed has proposed new requirement to measured material simultaneously, and anchor clamps must possess following condition:
1. the blade of tested blade must all appear, and can not there be any frequency modulated light object in the space.Therefore, the location of blade clamps and can only be selected on crude tenon or the listrium;
2. the coordinate axis of blade self and anchor clamps central lines.
Tenon, listrium all are the blank states, leave different process redundancy, make jig Design be difficult to find accurate in locating point position.For the coordinate axis that makes blade and the center line of anchor clamps coincide, can only adjust the position of each anchor point according to the data of the unique point of blade, require therefore that each anchor point is adjustable on the anchor clamps.The structure of turbo blade is mostly similar, can be with similar structure, for the integrated design of clamp structure typification provides condition to these class anchor clamps.
Summary of the invention
The utility model its objective is the measured material that a kind of integrated design is provided for the hot investment casting turbo blade just at the present situation of above-mentioned prior art and design the measured material that a kind of hot investment casting turbo blade is provided.
The purpose of this utility model realizes by following measure:
The measured material of this kind hot investment casting turbo blade, it is characterized in that: these anchor clamps have the pedestal of a U type, on the side of the indent die cavity of the pedestal of U type and bottom surface, six locating devices are installed, these six locating devices correspond respectively to the anchor point of choosing on hot investment casting turbo blade listrium and tenon, locating device is made up of locking ball, pedestal, adjuster bar and gib screw, adjuster bar is installed in the pedestal, front end withstands locking ball, the rear end installs and fixes screw, in addition, on the base body of U type, also be provided with a clamping screw.
This measured material anchor point is selected on the listrium and tenon of blade, and measured material adopts integrated design, and anchor clamps are by matrix, and locating device and clamping screw are formed.Locating device all is fixed on the identical pedestal, and to different blades, the length of clamp base is identical with width dimensions, is convenient to change.
Because blade listrium and tenon all are the blank states, leave different process redundancy, when jig Design, be difficult to determine the position of locking ball.In order to find the coordinate axis of blade self, the position of six anchor points will be regulated repeatedly when anchor clamps were adjusted.For reaching this purpose, the locating device that the utility model adopts and the assembly of pedestal, locating device is made up of locking ball, pedestal, adjuster bar, gib screw.For the coordinate axis and the measuring tool matrix central lines that make blade, the position of each locking ball is adjustable.Measuring tool uses the back anchor point to have wearing and tearing for a long time, will readjust anchor clamps.Locking ball uses the standard steel ball.Wearing and tearing backs if a position of rotation or renew just passable.

Embodiment
Below with reference to drawings and Examples the utility model is further described:
Shown in accompanying drawing 1～4, the measured material of this kind hot investment casting turbo blade, it is characterized in that: these anchor clamps have the pedestal 2 of a U type, on the side of the indent die cavity of the pedestal 2 of U type and bottom surface, six locating devices 9 are installed, these six locating devices 9 correspond respectively to the anchor point of choosing 1 on hot investment casting turbo blade 3 listriums and tenon, anchor point 1 can guarantee that blade 3 all appears when measuring, and be not in the light in the space, locating device 9 is by locking ball 4, pedestal 5, adjuster bar 6 and gib screw 7 are formed, adjuster bar 6 is installed in the pedestal 5, front end withstands locking ball 4, the rear end installs and fixes screw 7, in addition, on pedestal 2 bodies of U type, also be provided with a clamping screw 8.
The position of the locking ball 4 on each locating device 9 overlaps with anchor point 1 on the blade 3 when blade 3 clampings.Length and width size for the pedestal 2 of different blade 3 anchor clamps is identical.It is more convenient to change anchor clamps when measuring different blade.
By adjusting the position location be installed in six locating devices 9 on the clamp base 2 repeatedly, make the coordinate axis and the anchor clamps central lines of blade 3 self.
When anchor clamps were adjusted, pedestal 5 was fixed on pedestal 2, and realize with the length that changes adjuster bar 6 position of locking ball 4.The position that gib screw 7 is all being tightened during each the adjusting.As long as blade 3 correctly is installed on the anchor point of six locating devices, compress during use, just can guarantee correct location and the installation of blade on anchor clamps, thereby realize the requirement of measuring system measured material with clamping screw 8.
The utility model anchor clamps compared with prior art have accurate positioning, reliable, advantage easy to adjust.
