Abstract
This invention relates to an on-line measurement of central collimation of a three-roll centering device of a steel pipe perforator, wherein, the three-roll centering device comprises a plurality of clasping mechanisms arranged in sequence and order and the measurement comprises the following steps that: firstly, all clasp rods of each clasp mechanism is clasped towards a central position so as to form an actual center and each clasping mechanism is provided with a frock used for fixing a laser transmitter or a receiver and a laser transmitter is arranged at the frock at the end part; secondly, a laser line which is similar to a clasp center of the first clasp mechanism and the last clasp mechanism is arranged between the first and the last clasp mechanism to be served as a reference line; thirdly, points are sampled from the front part and the rear part of each clasping mechanism and thrust trolleys in sequence and a laser signal receiver is used for receiving measurement signals so as to obtain two-dimensional space coordinates of each measured points relative to the reference line and fourthly, average values of each two-dimensional space coordinate obtained from the third step is calculated to obtain precise measurement values.
Description
Technical field
The present invention relates to steel tube punching machine, relate to a kind of detection method of steel tube punching machine three rod centring means particularly.
Background technology
Perforating steel pipe is the first road technology that steel tube factory's tubing is produced, this technology is the prerequisite of control end product quality, can accurately hold the time of day of punch group switching centre, most important for the quality index of guaranteeing aspects such as steel pipe pipe thickness uniformity, steel tube surface fineness.
The punch group switching centre is mainly led position, outlet by pusher, memorial archway, inlet and is led position, three rod centring means and mandril anti-thrust seat etc. and partly forms, and archicenter absolute altitude benchmark is positioned at the medial surface of memorial archway, and the center reference plane is positioned at unit two ends from beginning to end.Therefore, the three rollers centering of perforation unit and the assurance examination of relevant device spatial relation are guaranteed constant product quality and the normal key factor of the production order.
For this reason, the steel tube factory is regularly detected the center of perforation unit, relevant device is changed and is adjusted, thereby guarantee product quality and set steady operation.Because it is very high that the spatial relation certainty of measurement of perforation unit three rod centring means and relevant device requires, device space layout complexity, and produce for streamline, can not provide the abundant repair time for an operation, otherwise the cost of overhaul is too high.Therefore also there is certain technical difficulty in the virtual condition that will hold the punch group switching centre under off-line and online two states accurately and effectively.
At present, the traditional measurement method that the steel tube factory only adopts the theodolite angle measurement and hangs steel wire detects the center line under the unit three rod centring means off-line states, though this method can be finished the collection of field data, can't satisfy the requirement of production technology, main deficiency is:
(1) the measuring instrument angle measurement accuracy is low, and aiming, accuracy of alignment is poor;
(2) measuring speed is slow, stability and reliability is poor as a result;
(3) datum mark on the memorial archway need adopt the method people who hangs steel wire for finding out, and measured deviation is big;
(4) measurement efficient is low, and measurement data is single, and the spatiality relation of Other related equipment can't in time be provided;
(5) off-line measurement can only be finished, the on-line measurement of three-roller centring device can not be carried out.
Summary of the invention
The present invention is intended to solve the above-mentioned defective of prior art, and a kind of steel tube punching machine three-roller centring device center alignment degree on-line measurement method is provided.Method certainty of measurement height of the present invention, data are abundant, and the efficient height, for the online detection of three-roller centring device provides solution.
A kind of steel tube punching machine three-roller centring device center alignment degree on-line measurement method, described three-roller centring device comprise that several that be arranged in order one by one report tight mechanism, and described measuring method comprises the following steps:
Step 1 is held the rod of holding tightly of each hold-fast body tightly to the center, form its practical center; The frock that is used for fixing generating laser or recipient is installed on each hold-fast body, and in the end a tail end frock is installed a generating laser;
Step 2 is utilized described generating laser, lays a laser rays that is similar to their centers of holding tightly as the reference datum line at first and last hold-fast body centre;
Step 3 is got a little on the head and the tail of each hold-fast body and anti-thrust trolley successively, utilizes the laser signal recipient to accept measuring-signal, obtains the two-dimensional space coordinate of institute's measuring point for the reference data line;
Step 4, the each point two-dimensional space coordinate averaged that step 3 is obtained promptly gets accurate measured value.
Described a kind of steel tube punching machine three-roller centring device center alignment degree on-line measurement method, in the middle of the described step 3, each point two-dimensional space coordinate is to be initial point with the reference data line, perpendicular to the coordinate system of reference data line through the little coordinate plane in plane of measuring point.
Described a kind of steel tube punching machine three-roller centring device center alignment degree on-line measurement method, described each point are the average out to value of two groups of coordinate figures recording when two corresponding points with receiver for the two-dimensional space coordinate of reference data line.
The present invention can onlinely implement fast detecting to three-roller centring device, the precision height, and further utilize the coordinate average to eliminate measure error, and improving certainty of measurement, the result is accurate, for steel pipe's production provides effective quality assurance means.
The specific embodiment
A kind of steel tube punching machine three-roller centring device of the present invention center alignment degree on-line measurement method, described three-roller centring device comprise that several that be arranged in order one by one report tight mechanism, and described measuring method comprises the following steps:
Step 1 is held the rod of holding tightly of each hold-fast body tightly to the center, form its practical center; The frock that is used for fixing generating laser or recipient is installed on each hold-fast body, and in the end a tail end frock is installed a generating laser;
Step 2 is utilized described generating laser, lays a laser rays that is similar to their centers of holding tightly as the reference datum line at first and last hold-fast body centre;
Step 3, on the head and the tail of each hold-fast body and anti-thrust trolley, get a little successively, utilize the laser signal recipient to accept measuring-signal, obtain the two-dimensional space coordinate of institute's measuring point for the reference data line, described each point two-dimensional space coordinate is to be initial point with the reference data line, perpendicular to the coordinate system of reference data line through the little coordinate plane in plane of measuring point;
