Abstract
The utility model provides a path detecting control device of steel tube diameter enlarging cylinder, which is characterized in that: an installation sleeve is connected with the back cylinder cover of the main cylinder of the diameter enlarging machine, a rack is fixed on the installation sleeve; an installation block is connected with the extension rod of the main cylinder, a bracket is fixed on the installation block, a gear device is hinged with the bracket; the gear device is composed of a gear set mounting plate and a gear set, each gear of the gear set are assembled on the mounting plate; a spring is arranged between the mounting plate of the gear set and the bracket to enable the primary gear of the gear set to be meshed with the rack without clearance; a rotary encoder is arranged at the axial end of the last stage axis of the gear set. The utility model has the advantages that because the pinion and rack apparatus, the rotary encoder detection, and controlling of the path quantity of the main cylinder piston are adopted, the anti-pollution ability of path detecting control mechanism is improved, the reliability of the detecting control mechanism work is guaranteed; and adopting the apparatus can reduce more than a half compared with the raster ruler detection of the prior art.
Description
Technical field
The utility model relates to a kind of oil cylinder stroke detection control apparatus, particularly a kind of when being used for pipe expanding to oil cylinder stroke carry out accurately, the device of reliable detection and control.
Background technology
When longitudinal submerged arc welded pipe is carried out hole enlargement, need the accurately path increment of control hole enlargement oil cylinder, to guarantee by the diameter precision of expanding steel tube.External expanding machine adopts grating chi and digital control system to jointly control the oil cylinder stroke amount, but it is high that the grating chi requires the working environment cleannes, and contamination resistance is relatively poor, under the more environment of dust and greasy dirt, the reliability that detects control reduces, and adopts grating chi cost higher.
Summary of the invention
The purpose of this utility model is to provide a kind of and can accurately detects and control oil cylinder stroke when pipe expanding, and reliable operation, pipe expanding oil cylinder stroke detection control apparatus with low cost.
For achieving the above object, the technical scheme taked of the utility model is:
A kind of pipe expanding oil cylinder stroke detection control apparatus is characterized in that: connect an installation sleeve on expanding machine master cylinder back cylinder cover, fix a toothed rack on installation sleeve; On extension bar behind the master cylinder, connect a mounting blocks, on mounting blocks, fix a bearing, a hinged geared system on bearing; Geared system is made of gear train installing plate and gear train, and each gear in the gear train all is assemblied on the installing plate; Be pulled between gear train installing plate and the bearing with a spring, make the primary pinion of gear train and tooth bar do the engagement of no gap; Final stage axle axle head at gear train is installed a rotary encoder.
The above-mentioned pipe expanding oil cylinder stroke detection control apparatus that the utility model provides, owing to adopted pinion and rack to add the path increment that the rotation encoder detected, controlled main oil cylinder piston, improve the contamination resistance of stroke detection controlling organization, guaranteed to detect the reliability of controlling organization work; Adopt said mechanism than adopting the detection of grating chi can reduce cost over half.

The specific embodiment
As shown in Figures 1 to 4, among the pipe expanding oil cylinder stroke detection control apparatus embodiment that the utility model provides, as can see from Figure 1: on expanding machine master cylinder back cylinder cover 1, connect an installation sleeve 2, on installation sleeve 2, fix a toothed rack 3; On extension bar behind the master cylinder 4, connect a mounting blocks 5, on mounting blocks, fix a bearing 6; Can see in conjunction with Fig. 3, Fig. 4: a hinged geared system 7 on bearing 6, geared system 7 is made of gear train installing plate 8 and gear train, and each gear in the gear train all is assemblied on the gear train installing plate 8; Be pulled between gear train installing plate 8 and the bearing 6 with a spring 9, make the primary pinion 10 of gear train and tooth bar 3 do the engagement of no gap; As can see from Figure 2: the final stage axle axle head at gear train is installed a rotary encoder 11.
The course of work of above-mentioned pipe expanding oil cylinder stroke detection control apparatus is: when expanding machine carries out hole enlargement, the main oil cylinder piston bar moves backward, connect firmly at the gear train primary pinion on the extension bar behind the master cylinder and on fixing tooth bar, roll, the rectilinear motion of piston is converted to the circular motion of gear---rotate, detect the angular displacement of this rotation again by rotary encoder, and electric impulse signal passed to the steel tube expansion engine control system, control system provides signal when detecting the predetermined stroke amount, main oil cylinder piston is stopped, thereby control the path increment of main oil cylinder piston accurately and reliably.
