Abstract
The utility model relates to a T-shaped machine tool error tester which is provided with two ball arrays which are mutually perpendicular and are fixedly connected, and an auxiliary positioning rod, wherein, 2n+1 spheres which are equidistantly arranged are distributed on a ball rod (1); n+1 spheres which are equidistantly arranged are distributed on the ball arrays (2); the auxiliary positioning rod and the ball arrays (2) are fixedly connected and parallel, and the auxiliary positioning rod is positioned in a plane formed by the two ball arrays. The T-shaped machine tool error tester can test out the 21-item mechanism errors of machines along 11 axial straight lines by six positioning sites. When testing, only one tested positioning site is adjusted and positioned, and the entire six positioning sites can be determined.
Description
The utility model relates to a kind of cubing of measuring coordinate class machine space errors such as lathe, coordinate, measuring machine.
The method of measuring coordinate class machine mechanism space errors such as lathe, coordinate measuring machine at present has: the direct method of measurement, linear movement measuring method and one dimension spherical column method.The direct method of measurement needs the various analytical measurement utensils or the instrument of One's name is legion, and it is big, time-consuming that the detection step is many, workload is adjusted in the location, and measuring period is long, measuring accuracy is low.The displacement of the lines method need be used expensive laser interferometer, the cost of equipment height, the use of instrument, management, adjustment requirement condition height, expense are big, although thereby measuring accuracy height, result are accurate, except that large-scale professional production factory and research and development unit can dispose use general machine works and coordinate class lathe factory seldom use.The one dimension spherical column method is to utilize by a straight-bar and be arranged in one dimension spherical column that a series of steel balls on the straight-bar constitute to carry out the measurement of 21 mechanism errors of machine as the straight line of standard component outside 16 specific position locations and then obtain the precision that the mechanism space error and the machine of machine are reached, this method cubing is simple in structure, cost is low, but in order to finish along the measurement of 16 straight lines, cubing need be carried out the location adjustment of 16 position locations, space, this location comprising the space oblique line is adjusted, thereby it is big to adjust workload, troublesome poeration, waste time and energy, cause sense cycle longer.In a word, utilize existing method and cubing to measure the mechanism error of machine, its sense cycle is all more than 20 hours, thereby is unfavorable for that productivity uses.
The purpose of this utility model provides a kind ofly measures that coordinate class machine space mechanism errors such as lathe, coordinate measuring machine use, cubing is simple in structure, cost is low, and the location is adjusted, the detection step is few, easy and simple to handle, sense cycle is short, the T shape machine tool error cubing that measuring accuracy is high.
T shape machine tool error cubing is made of two orthogonal ball row, ball row (1) are connected to the middle part that ball is listed as (1) mutually with ball row (2), 2n+1 the spheroid that equidistant arrangement is arranged on the ball row (1), n+1 the spheroid that equidistant arrangement is arranged on the spheroid (2), ball row (1) upper sphere is identical with ball row (2) upper sphere sphere diameter.When sphere gap was S, ball row (1) maximum length was 2nS, and ball row (2) maximum length is nS.N is any natural number.Ball row (1) and ball row (2) junction spheroid mutually are that n+1 ball of ball row (1) is listed as first ball of (2) simultaneously for ball.
Utilize T shape machine tool error cubing to measure 21 mechanism errors of machine, only need carry out the adjustment of six position locations and measure the measurement that can finish whole projects along 11 axial straight lines, measuring operation is simplified greatly, shorten measuring period greatly.
The further improvement of T shape lathe cubing is that auxiliary positioning bar both ends are fixedly connected with spheroid at the ball row fixedly connected auxiliary positioning bar of (2) free end (3), and it is identical that its spheroid sphere diameter and ball list the spheroid sphere diameter.Auxiliary positioning bar and ball row (1) are parallel and be positioned at the plane that ball row (1) and ball row (2) constitute, and ball row (1) have supporting (4) and (5) to make the cubing distortion that is difficult for being distorted, the use and the measuring accuracy of assurance cubing with raising cubing rigidity.
Setting by the auxiliary positioning bar, by six position locations during along the mechanism error of 11 axial line measurement machines, only need carry out the location adjustment of first position location and whole measurement and positionings position can be determined and then carry out the measurement of error, thereby further reduced location adjustment operation numerous and diverse, trouble, sense cycle is further shortened, satisfied the requirement that productivity is used.
Utilize T shape machine tool error cubing to measure 21 mechanism errors of machine, not only simplified measuring operation, shortened the measuring operation cycle significantly, and when measuring, only need know that the accurate sphere gap between spheroid can record the exact value of every error, and the deviation of the linearity of each ball row of cubing and the verticality between two balls row is told voluntarily by cubing in measuring process and the measuring accuracy of cubing is had no effect.Because these characteristics of cubing, manufacturing, use, the maintenance of cubing are more prone to and make things convenient for.
Accompanying drawing is an example structure figure of the present utility model, further specifies the utility model below in conjunction with accompanying drawing.
Fig. 1 is a T shape machine tool error cubing structural drawing.
Fig. 2-7 is the measurement and positioning synoptic diagram.
