Abstract
The utility model provides a parallel measuring device of large -scale lathe bed way is one kind and detects the precision height, easily operates and detect the lower large -scale lathe guide rail depth of parallelism detection device of cost, including the leveling ruler that matches with left guide rail and right guide rail respectively, the leveling ruler left end be fixed with cylindrical ka jiao, the leveling ruler right -hand member on be fixed with laser displacement sensor, laser displacement sensor be connected with the PC computer terminal, the leveling ruler on be equipped with the spirit level. Because the utility model discloses utilize the line contact location, laser is measured, therefore the precision is higher, just the utility model discloses simple structure and convenient to detach, be convenient for easily operation and transportation.
Description
Technical field
The utility model relates to a kind of checkout equipment, particularly relates to a kind of Parallel testing equipment, specifically refers to a kind of heavy duty machine tools guide rail parallelism pick-up unit.
Background technology
At present in Machine Manufacture field, require very high to the depth of parallelism of the guide rail that lathe is provided with, particularly in some heavy duty machine tools, the span of its guide rail is very large, and after client buys lathe, guide rail is generally install after lathe is transported to client there again.
Former guide rail after mounting, for ensureing the depth of parallelism between two guide rails, general employing high precision tape measure is directly measured the spacing between two guide rails, although this measuring method is easy to operation, can not meet the requirement of lathe to two guide rail high depth of parallelisms because precision is too poor.Measuring the measuring accuracy of the depth of parallelism to improve, also having a kind of machine tool guideway detector at present, the high-acruracy survey to guide rail parallelism can be realized, but due to the price comparison of this machine tool guideway detector expensive, higher for testing cost enterprise.
Summary of the invention
Utility model object: the utility model provides a kind of Large Machine Body guide rail parallelism measurement mechanism, its objective is the problem existing for solution equipment in the past.
Technical scheme: the utility model is achieved through the following technical solutions:
A kind of Large Machine Body guide rail parallelism measurement mechanism, it is characterized in that: the leveling ruler matched with left rail and right guide rail when the main body of this device is use, the card base inside left rail or right guide rail is stuck in when a side bottom of leveling ruler is provided with use, bottom the opposite side of described leveling ruler, be provided with the laser displacement sensor be connected with PC computer terminal, the top of leveling ruler is provided with level meter.
Card base is the cylindrical card base contacted with guide rail inside cord.
Laser displacement sensor, its minimum division value is 0.001mm, and measurement range is 30mm.
Described leveling ruler is magnalium leveling ruler.
Advantageous effect: the utility model provide a kind of accuracy of detection high, be easy to operate and the lower heavy duty machine tools guide rail parallelism pick-up unit of testing cost, comprise the leveling ruler matched with left rail and right guide rail respectively, described leveling ruler left end is fixed with cylindrical Ka Jiao, described leveling ruler right-hand member is fixed with laser displacement sensor, described laser displacement sensor is connected with PC computer terminal, and described leveling ruler is provided with level meter.
After adopting above scheme, the utility model heavy duty machine tools guide rail parallelism pick-up unit utilizes level meter accurately to ensure the contour of left and right bed ways.When measuring, the utility model, without the need to measuring the spacing between two guide rails, waves the right-hand member of leveling ruler among a small circle about each measurement point, and the registration minimum value of reading laser displacement sensor can draw the depth of parallelism between two guide rails easily.Because the utility model utilizes linear contact lay to locate, laser is measured, and thus precision is higher, and the utility model structure is simple and be convenient to dismounting, is convenient to be easy to operation and transport.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Number in the figure title: 1 is cylindrical card base; 2 is level meter; 3 is leveling ruler; 4 is left rail; 5 is laser displacement sensor; 6 is right guide rail; 7 is PC computer terminal.
embodiment:below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, the utility model provides a kind of Large Machine Body guide rail parallelism measurement mechanism, the leveling ruler 3 matched with left rail 4 and right guide rail 6 when the main body of this device is use, the card base 1 inside left rail 4 or right guide rail 6 is stuck in when a side bottom of leveling ruler 3 is provided with use, bottom the opposite side of described leveling ruler 3, be provided with the laser displacement sensor 5 be connected with PC computer terminal 7, the top of leveling ruler 3 is provided with level meter 2.
Card base 1 is the cylindrical card base contacted with guide rail inside cord.Be provided with reading datum line by the principle of linear contact lay location, decrease the error of contact location, face, improve the precision of measurement and be convenient to implement
Laser displacement sensor, its minimum division value is 0.001mm, and measurement range is 30mm, and not only precision is high but also avoid the accident causing dial gauge to damage because of human operational error, and the precision of the measurement adopting this programme to make brings up to thousand points of positions.It has not yielding, precision is high, use the features such as light, significantly reduces the labour intensity of workman, to timing convenient operation, exploitativeness is strong, improves detection efficiency.
Described leveling ruler is magnalium leveling ruler.
Described level meter can measure the equal altitudes of two guide rails in real time, by adjusting the difference in height of two guide rails in real time, the reading of level meter is remained unchanged, thus reduces the parallelism error produced because of the change of two rail height differences, further increases testing accuracy.
Described level meter is placed on the centre position of leveling ruler, by adjusting the difference in height of two guide rails in real time, the reading of level meter is remained unchanged at each measurement point.
During measurement, leveling ruler left end card base is fixed, and left and right waves leveling ruler right-hand member by a small margin, observes the registration of laser sensor, finds out minimum value.
