Abstract
The utility model relates to a detecting device used for measuring the turbine blade rivet head pitch, particularly to a turbine blade rivet head pitch detecting device which comprises a standard vernier caliper with a meter. The utility model is characterized in that caliper measuring feet are composed of caliper feet and blocks, gaps are arranged between the caliper feet and the blocks which protrude out of the caliper feet, and the caliper feet and the blocks are not in the same plane. A pair of caliper feet and blocks are fixed on the lower end of the caliper as the measuring start position, the other pair of caliper feet and blocks are fixed on the lower end of a vernier as the measuring position, two caliper feet form one measuring plane, and two blocks are used as measuring blocking blocks. Two blocks form one plane. The utility model can measure the actual pitch data of the blade rivet head effectively, accurately and visually after a rotor blade is assembled, qualified cover bands can be manufactured after the actual pitch data is input into a numerical control machine, thereby, the rivet bond quality of the cover bands and the blade rivet head is enhanced.
Description
(1) technical field
The utility model relates to a kind of pick-up unit that is used for MEASUREMENT OF STEAM turbine blade manufactured head pitch.
(2) background technology
After pressing the blade assembling in the steam turbine, the manufactured head on its leaf top must be riveted together with shroud general blade in groups could guarantee the normal duty of blade.Because of blade is to be in high temperature, high pressure, high-speed motion state, the riveted joint of shroud and vane rivet head requires very high, and after the blade assembling, the manufactured head pitch and the theoretical value that are in circumference leaf top have difference, therefore the processing of shroud rivet hole must be measured the adjacent two manufactured heads positive and negative deviation value of this grade impeller shroud nominal value relatively with measurer certain location on assembled blade.Early stage processing technology is to measure the pitch of vane rivet head with gage, and the router marks the rivet hole position on processed shroud, go out rivet hole with punch press by scribing position.Because this kind method measuring accuracy is relatively poor, shroud is generally done shortlyer, and promptly one section shroud can only be with several blades (manufactured head) riveting together.After adopting numerically-controlled machine that the shroud hole is processed, higher requirement has just been proposed for the positional accuracy measurement of manufactured head on the blade.
(3) summary of the invention
The purpose of this utility model is to provide a kind of turbine blade manufactured head pitch pick-up unit, this pick-up unit can be measured the actual pitch data of spinner blade assembling rear blade manufactured head effectively, accurately, intuitively, can process qualified shroud behind the input numerically-controlled machine, thereby improve the riveting quality of shroud and vane rivet head.
The utility model is achieved in that a kind of turbine blade manufactured head pitch pick-up unit, comprise index zone table vernier caliper, it is characterized in that slide calliper rule survey pin by the slide calliper rule pin with form by piece, the slide calliper rule pin is with gapped by interblock and by the outstanding slide calliper rule pin of piece, the slide calliper rule pin with by piece not in a plane, a pair of slide calliper rule pin and be fixed in the slide calliper rule lower end as measuring start bit by piece, another is fixed in the vernier lower end as measuring the position to the slide calliper rule pin with by piece, two slide calliper rule pin are formed a measurement plane, and two are leaned on piece as measuring block.
Above-mentioned turbine blade manufactured head pitch pick-up unit, described two are leaned on piece to form a plane.
The utility model is to reconstruct on the basis of index zone table vernier caliper, is about to two surveys of index zone table vernier caliper pin and clips one section, loads onto two and contains slide calliper rule pin and the special use survey pin that lean on piece.During use, will show school zero by tested impeller progression with the standard pitch gauge block, according to shroud rivet hole job sequence in the deviate round off number controlled machine of tested manufactured head pitch.The utility model can be measured the actual pitch data of spinner blade assembling rear blade manufactured head effectively, accurately, intuitively, can process qualified shroud behind the input numerically-controlled machine, improve the riveting quality of shroud and vane rivet head, thereby overcome the defective that adopts the measuring accuracy difference that the gage measurement brings in the past.
(4) description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model turbine blade manufactured head pitch pick-up unit structural representation;
Fig. 2 is the structural representation that two slide calliper rule are surveyed pin.
Among the figure: 1 slide calliper rule, 2 verniers, 3 indicating gauges, 4 slide calliper rule pin, 5 by piece, 6 screws, 7 manufactured heads.
(5) embodiment
Referring to Fig. 1, Fig. 2, a kind of turbine blade manufactured head pitch pick-up unit comprises index zone table vernier caliper, and slide calliper rule are surveyed pin and are made up of with leaning on piece 5 slide calliper rule pin 4, slide calliper rule pin 4 and gapped and by piece 5 outstanding slide calliper rule pin 4 by 5 of pieces, slide calliper rule pin 4 with by piece 5 not in a plane.A pair of slide calliper rule pin 4 and be fixed in slide calliper rule 1 lower end as measuring start bit by piece 5, another is fixed in vernier 2 lower ends as measuring the position to slide calliper rule pin 4 with by piece 5, two slide calliper rule pin 4 are formed a measurement plane, and two are leaned on piece 5 also to form a plane, and two are leaned on piece 5 to play the effect of measurement block.Slide calliper rule among the figure are surveyed pin according to the repacking of index zone table vernier caliper, produce to be fixed on the standard slide calliper rule survey pin with screw 6 after pin is surveyed in special use.
Referring to Fig. 1, during use, with the standard pitch gauge block that indicating gauge 3 schools are zero by tested impeller progression, pick-up unit is leaned against on the turbine blade manufactured head 7, a slide calliper rule pin 4 of slide calliper rule 1 props up a manufactured head 7, blocks manufactured head 7 tops by piece 5, makes that vernier caliper is difficult for moving; Pulling vernier 2, the slide calliper rule pin 4 that will be fixed in vernier 2 bottoms be by last another manufactured head 7, and corresponding with this slide calliper rule pin 4 blocks manufactured head 7 tops by piece 5.The numeral that shows on the indicating gauge 3 of turbine blade manufactured head pitch pick-up unit is the positive and negative deviation value of adjacent two manufactured heads, 7 relative this grade impeller shroud nominal values like this.
Claims (2)
1. turbine blade manufactured head pitch pick-up unit, comprise index zone table vernier caliper, it is characterized in that slide calliper rule survey pin by the slide calliper rule pin with form by piece, the slide calliper rule pin is with gapped by interblock and by the outstanding slide calliper rule pin of piece, the slide calliper rule pin with by piece not in a plane, a pair of slide calliper rule pin and be fixed in the slide calliper rule lower end as measuring start bit by piece, another is fixed in the vernier lower end as measurement to the slide calliper rule pin with by piece, two slide calliper rule pin are formed a measurement plane, and two are leaned on piece as measuring block.
