Description
Technical field
The utility model is related to header cylinder datum line field of locating technology, and in particular to a kind of base of header cylinder line
Directrix positioner.
Background technology
Boiler header is one of core component of boiler, and the quality of its quality directly influences the performance of whole boiler.By
It is various in the species and quantity of header, and perforate in header is very more, it is ensure position of opening in header accurate, it is actual
Need first to set four-quadrant on header cylinder during processing, uniformly positioned for pore.
In order to ensure the accuracy of perforate, the technological requirement of header cylinder line is very strict, it is necessary to be accurate to 0.5mm with
Interior error, general line technique used is first to take two support frames, after water detection is flat, header cylinder is laid flat, with height
Micrometer connects two midpoint position baselines at header cylinder two ends Ge Qu midpoints.And in actual operation, because of header cylinder
It is circle, in the case of no horizontal stand, the method is not only troublesome but also does not reach accuracy regularly, causes header to be rule and turns round
Song, quality inspection personnel also is difficult to inspection, influences product quality.
Therefore line reference positioning can be entered in the case where header cylinder is arbitrarily placed it is highly desirable to one kind so that header cylinder
The position that body is placed no longer is limited by horizontal stand, can effectively improve operating efficiency and easy to operate, accurate positioning.
The content of the invention
Datum line for a kind of header cylinder line that the problems of in the prior art, the utility model is provided is determined
Position device, it is possible to achieve the position that header cylinder is placed no longer is limited by horizontal stand, and effectively improves operating efficiency and behaviour
Make easy, accurate positioning.
To achieve these goals, the technical solution adopted in the utility model is as follows：
A kind of datum line positioner of header cylinder line, including matrix, horizontal bubble and screw, set in described matrix
It is fluted, run through for the fixation with header cylinder position, on the central axis of the groove floor and be connected with screw, the spiral shell
The determination for datum line anchor point after the centering of header two ends is followed closely, described matrix bottom surface is provided with horizontal bubble, described level
Bubble is used for the centering of matrix horizontal level on header cylinder.
Preferably, described matrix is set to 10# channel-section steels.
Preferably, the midpoint of the screw and horizontal bubble is on same level axis.
Preferably, the screw-tipped is connected with sample drift, for carrying out sample punch mark on header cylinder.
The beneficial effects of the utility model show：Operating efficiency is effectively improved, by horizontal bubble so that matrix
Quickly and accurately find positioning accurately on header cylinder, and marked rapidly by screw, it is convenient and swift, alleviate work people
The labour intensity of member so that the position that header cylinder is placed no longer is limited by horizontal stand, improves operational stability and efficiency,
And easy to operate, accurate positioning, greatly improve the work quality of workman.

Specific embodiment
For the ease of it will be appreciated by those skilled in the art that being further described to the utility model below in conjunction with the accompanying drawings.
A kind of datum line positioner of header cylinder line as Figure 1-4, including matrix 1, horizontal bubble 2 and spiral shell
Nail 3, described matrix 1 is set to 10# channel-section steels, for the fixation with the position of header cylinder 4, on the central axis of the bottom surface of described matrix 1
Through screw 3 is connected with, the screw 3 is used for the determination of datum line anchor point after the two ends centering of header cylinder 4, the screw 3
Tip is connected with sample drift, and for carrying out sample punch mark on header cylinder 4, the bottom surface of described matrix 1 is provided with horizontal bubble 2,
The horizontal bubble 2 can be set to the horizontal bubble 2 on the devices such as horizontal bubble chi, and described horizontal bubble 2 exists for matrix 1
The midpoint of the centering of horizontal level on header cylinder 4, the screw 3 and horizontal bubble 2 is on same level axis.
When using, as long as header cylinder 4 is arbitrarily placed, the matrix 1 that will be inlaid with horizontal bubble 2 is anchored to header cylinder 4
One end on, then adjusting matrix 1 makes horizontal bubble 2 placed in the middle, is beaten at the meaning of screw 3 and equally rushed, and then same mode exists
The other end of header cylinder 4, takes a little to beat successively and equally rushes, and 2 points of connection is position baseline, and then datum line looks for it according to this
His each line；Therefore, the position that header cylinder 4 is placed no longer is limited by horizontal stand, can effectively improve operating efficiency and operation
Easy, accurate positioning.
Above content is only to structure example of the present utility model and explanation, the technology of affiliated the art
Personnel are made various modifications or supplement to described specific embodiment or are substituted using similar mode, without departing from
The structure of utility model surmounts scope defined in the claims, all should belong to protection domain of the present utility model.
