Description
Technical field
The utility model relates to a kind of inner chamber and hooks groove and plane detection centering apparatus, belongs to field of machining.
Background technology
Multiple ring is the vital part on gas turbine, dimensional accuracy and position accuracy demand are all very high, complicated structure, because it is arranged in combustion machine turbine cylinder by T-shaped annular groove, therefore T-shaped annular groove locating surface requirement is very high, once error is excessive, will have influence on the installation accuracy of multiple ring in turbine cylinder, and then have influence on the gap of multiple ring gas sealing strip and turbine rotor, cause and reprocess.The parts of location are installed by complicated annular groove for this class, we will ensure their installation accuracy as far as possible, this has just proposed very high accuracy requirement to dimensional accuracy and the form and position tolerance of complexity installation annular groove, so in will T-shaped annular groove being detected and looked for before use, not yet find in the market relevant product.
Summary of the invention
The purpose of this utility model is to provide a kind of inner chamber and hooks groove and plane detection centering apparatus, raising encircles again the detection of T-shaped annular groove and other complex parts and looks for middle precision, improve to detect and look for middle efficiency, the inner chamber of reprocessing and the detecting hook groove and the plane that solve the complicated annular groove in various parts installation location detect centering apparatus.
For addressing the above problem, technical solution adopted in the utility model is:
A kind of inner chamber hooks groove and plane detects centering apparatus, comprise dial gauge, also comprise connecting and support and contact web joint, the test rod that one end connects dial gauge is supported in described connection, the other end is connected with one end of contact web joint, described connection support is vertical with one end that contact web joint is connected, and the other end of contact web joint arranges contact, described contact be connected supports parallel.
As further improvement of the utility model, described contact web joint is " one " font, and described contact is vertical with contact web joint, and described contact supports with being connected the both sides that are separately positioned on contact web joint.
As further improvement of the utility model, one end that described contact web joint is installed contact has third through-hole, and one end of described contact is arranged in third through-hole.
As further improvement of the utility model, described contact web joint is L-shaped, one end that described contact web joint is connected with contact and contact conllinear, and described contact supports with being connected the both sides that are separately positioned on contact web joint.
As further improvement of the utility model, one end that described contact web joint is installed contact has the 3rd blind hole, and one end of described contact is arranged in the 3rd blind hole.
Further improve as of the present utility model, one end that described connection support is connected with the sounding rod of dial gauge has the first blind hole, its side has the first through hole communicating with the first blind hole, the sounding rod bottom of dial gauge is stretched in the first blind hole, in the first described through hole, be provided for the sounding rod and the first bolt that is connected support of fixing dial gauge, one end that described connection support is connected with contact web joint has the second blind hole, this end of contact web joint has the second through hole, described the second blind hole (8) and the second bolt that is provided for being fixedly connected with support and contact web joint in the second through hole.
The beneficial effects of the utility model are: the utility model connects arrange vertical with contact web joint of support, dial gauge contact is installed on contact web joint, because the locating surface of T-shaped annular groove is in cylindrical the inside, therefore, by contact web joint, contact is reached to T-shaped annular groove the inside, contact with each locating surface of T-shaped annular groove respectively with contact.
The contact of " one " font changes contact and the distance being connected between supporting radially, contact can be extend in the narrow groove of T-shaped groove, contact is positioned at the both sides of contact web joint with being connected to support, and can make contact arrive the outer ring surface of T-shaped groove, and the outer ring surface of T-shaped groove is detected.
The contact of " L " font changes contact and the distance being connected between supporting radially, contact can be extend in the narrow groove of T-shaped groove, and can touch the anchor ring up and down of T-shaped groove, contact is positioned at the both sides of contact web joint with being connected to support, contact can touch upper ring surface or the lower anchor ring of T-shaped groove, only needs conversion installation direction contact of the present utility model can touch lower anchor ring or the pressed on ring of T-shaped groove.
The sounding rod of dial gauge is all bolted with being connected support, connection support and contact web joint, not only detachable, and is difficult for becoming flexible, and guarantees the accuracy of detection.
When use, the utility model is fixed on dial indicator bracket, with the multiple ring of T-shaped groove, with lathe worktable rotary one week, we just can pass through the display screen sense data of numerically-controlled machine very easily.The present invention is applicable to the detection that gas turbine encircles again, avoided traditional dial gauge cannot on multiple ring and the complexity of other various parts annular groove locating surface be installed carried out direct-detection, and the very high problem of other non-traditional pick-up unit cost such as laser.Adopt this kind of pick-up unit, processing detection efficiency, accurate to dimension and processing form and position tolerance precision are improved greatly, can quick and precisely detect processing dimension and morpheme error that multiple ring and other various complex parts are installed locating surface, ensure machining precision, the appearance of minimizing unacceptable product encircles while reducing assembling simultaneously again and other complex parts is installed positioning ring groove because the neutralization of again looking for overproof and generation is reprocessed.
