Abstract

The utility model provides a rapid transverse alignment device for tile block of tiltable bearing, which uses the cover of a tiltable tile to be a processing fixture of a vertical lathe. A meter support rod and a dial test indicator are fixed on a soleplate. An orientation is done by the inner hole of an oil barrier ring at the two ends of the tile cover and the head face of the soleplate. A contact at the end of the dial test indicator rod contacts with the tile block, and no extra fixture is needed. A transverse alignment is completed by the reading of the dial test indicator and the alignment can be done by a locksmith, rather than the vertical lathe on the ground quickly and correctly.

Description

The quick centering instrument of tilting-pad bearing tile fragment

Technical field

The utility model belongs to can the incline quick centering frock of watt sliding bearing tile fragment endoporus processing of Large Steam Turbine Sets.

Background technology

The Large Steam Turbine Sets watt sliding bearing that can incline is generally formed (referring to Fig. 1) by 4-6 tile fragment.Generally speaking, dolioform cylindrical of tilting pad and length dimension process earlier, and interior hole dimension must be of a size of benchmark by a watt cover endoporus, the fixing back turning of centering.Endoporus turning is the key in watt processing of can inclining, and because tilting pad is dolioform, how making the tile fragment position is that symmetrical (being centering) is again the key issue in the turning with respect to a watt centre of gyration that is enclosed within on the vertical lathe.Existing special frock centering, very trouble is also uneconomical.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, develops the quick centering frock of a kind of tilting-pad bearing tile fragment.

The purpose of this utility model is such realization: employing can be inclined watt watt cover as the processing tool of vertical lathe, is fixed with table pole and dial gauge on substrate, locatees with the oil scraper ring endoporus and the end face on the substrate at this watt cover two ends, and dial gauge rod end contact contacts with tile fragment.

Described endoporus and end face location are to adopt alignment pin and end face dog screw respectively.

Pole on the described substrate and dial gauge all adopt holding screw.

The utlity model has following advantage: directly utilization can be inclined watt watt cover as the vertical lathe processing tool, does not need other specialized designs frock; Utilize the dial gauge reading to carry out centering, do not need the vertical lathe centering, directly by pincers worker centering on the ground, centering work fast, accurately.Not having the such centering frock of the utility model in the past, is to adopt first.

Code name implication among the figure: 1. go up half-watt cover 2. first tile fragment 3. the tile fragment Hanging bolt 4. descend the 5. upper and lower half-watt of half-watt cover to overlap connection holes 6. to descend the half-watt cover; 10 watts of covers of 1 end face dog screw, 2 substrate 3 endoporus alignment pins, 4 table pole 5 holding screw 6 dial gauges, 7 holding screw 8 oil scraper ring endoporus, 9 tile fragments

The specific embodiment

Referring to Fig. 2-Fig. 4, employing watt cover 10 processing tools as vertical lathe that can incline watt are fixed with table pole 4 and dial gauge 6 on substrate 2, the end face location on the oil scraper ring endoporus 8 at this watt cover 10 two ends and the substrate 2, and dial gauge rod end contact contacts with tile fragment 9.Endoporus 8 and end face location are to adopt alignment pin 3 and end face dog screw 1 respectively.Pole 4 on the substrate 2 and dial gauge 6 all adopt holding screw (5,7).

Manipulate: (1) centering is with the line of coordinate points: with dividing the tile fragment that cuts off to place on the platform by the same side on the same tile fragment, mark the symmetrical feature point that centering is used with marking pen at the babbit endoporus; (2) with each tile fragment by in the half-watt cover of packing into successively for corresponding number up and down, utilize 3. preliminary tension location tile fragment of the Hanging bolt of tile fragment described in Fig. 1, closing watt puts second; (3) earlier at any end face of watt cover, utilize the described instrument of Fig. 4, two endoporus alignment pins 3 are leaned against on watt cover oil scraper ring endoporus 8, end face dog screw 1 is leaned against on watt cover 10 end faces; (4) guaranteeing that two endoporus alignment pins 3 lean against on watt basis of cover oil scraper ring endoporus 8 all the time, this instrument that slides is gently adjusted dial gauge 6 height and position and is made its table strut ends contact position be positioned at the symmetrical feature point place that (1) described centering is used; (5) two characteristic point places, more same tile fragment the same side dial gauge reading as variant, then adjusted the tile fragment centering of tilting pad shown in Figure 1 both sides and is adjusted screw, up to dial gauge 6 reading differences in the 0.02mm scope; (6) and the like other tile fragment of same side of centering tile fragment; (7) at another end face of watt cover, adopt two symmetrical centering characteristic points of the opposite side of same method of operating centering tile fragment, tension tile fragment Hanging bolt is 3.; (8) check watt dial gauge 6 differences at the centering characteristic point place of cover both sides tile fragment again, up to the dial gauge 6 reading differences that guarantee four characteristic points of each tile fragment all in the 0.02mm scope.

Claims

1. quick centering instrument of tilting-pad bearing tile fragment, it is characterized in that: the employing processing tool of watt watt cover that can incline as vertical lathe, be fixed with table pole and dial gauge on substrate, with the oil scraper ring endoporus and the location of the end face on the substrate at this watt cover two ends, dial gauge rod end contact contacts with tile fragment.

2. the quick centering instrument of tilting-pad bearing tile fragment according to claim 1 is characterized in that: endoporus and end face location are to adopt alignment pin and end face dog screw respectively.
