Abstract
The utility model discloses a kind of piston rod linearity testing apparatus, including workbench, workbench is equipped with several identical supporting blocks, several supporting block intervals are arranged and are arranged in a straight line, it is characterized in that being additionally provided with sliding rail on workbench, sliding rail is parallel with several supporting blocks being arranged in a straight line, and sliding rail is equipped with straightness detection mechanism, and straightness detection mechanism can be slided along slide direction.Accurate, the error smaller the utility model has the advantage of measuring.
Description
Technical field
The utility model is related to piston rod manufacturing fields, more particularly, to a kind of piston rod linearity testing apparatus.
Background technology
Because its straightness is bad in prior art piston bar blank process, the fraction defective of product is caused to increase, is electroplated
The unqualified blank that Shi Jing is verified scraps processing because no allowance can only be done, and increases production cost, does not conform to reduce
Lattice rate, the operator of blank production line must the visual examination before carrying, arbitrariness is also big for this check system, while operator
Workload increases, but still difficulty gathers effect, and the fraction defective of piston rod is difficult to decline.
A kind of inspection dress of piston rod straightness is disclosed in Chinese patent application prospectus, CN202304726U
Set assembly comprising horizontal positioned workbench, the workbench surface is horizontal, and workbench is spaced along its length
Two pieces of contour supporting blocks are set, linearity testing apparatus is provided between supporting block.But there is also as follows for the detection device
Problem：First, linearity testing apparatus is immovable, a general position for only detecting piston rod, and measurement data is excessively single；
Second, the detection instrument in linearity testing apparatus is not directly to be detected with piston rod, and measurement error is larger.
Invention content
The technical problem to be solved by the utility model is to provide a kind of piston rod linearity testing apparatus, it is intended to straight by this
Dimension detection device reduces measurement error.
Technical solution is used by the utility model solves above-mentioned technical problem：A kind of piston rod Linearity surveying dress
It sets, including workbench, the workbench is equipped with several identical supporting blocks, several supporting block intervals setting and row
In line, sliding rail is additionally provided on the workbench, the sliding rail is parallel with several supporting blocks being arranged in a straight line, described
Sliding rail be equipped with straightness detection mechanism, the straightness detection mechanism can slide along slide direction.
It is further improved as the utility model, the straightness detection mechanism includes sliding block, first support bar, second
Supporting rod and amesdial, sliding block sliding are set on sliding rail, and one end of the first support bar is connect with sliding block, described
One end of second support bar and the other end connection of first support bar and angle between the two it is adjustable, the amesdial
Table bar and the other end of second support bar connect, and the table bar of the amesdial tilts, and the contact end of the amesdial can
It is contacted with product is measured.
It is further improved as the utility model, the supporting block upper surface is equipped with V-groove.
Compared with prior art, accurate the utility model has the advantage of measuring, error smaller.
The utility model detection scheme：By piston bridge in several supporting blocks, make end and the body of rod merging V of piston rod
In type groove, the contact of amesdial is contacted with piston rod surface, is rotated clockwise piston rod by technician, rotation angle
Respectively 90 °, 180 °, 270 °, 360 °, and the numerical value of amesdial throw of pointer, then sliding slider are recorded, with above-mentioned identical
Measurement method surveys the numerical value at other positions of piston rod, these numerical value are calculated to the straight line of piston rod by specific formula
Degree；In addition, the angle that first support bar is connect with second support bar is adjustable, the scope of application of testing agency is further improved.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only explaining this
Utility model is not used to limit the utility model.
As shown in Figure 1：A kind of piston rod linearity testing apparatus, including workbench, workbench are equipped with several identical
Supporting block 1, the interval of several supporting blocks 1 are arranged and are arranged in a straight line, and sliding rail 2 is additionally provided on workbench, and sliding rail 2 lines up one with several
The supporting block 1 of straight line is parallel, and sliding rail 2 is equipped with straightness detection mechanism, and straightness detection mechanism can be slided along 2 direction of sliding rail
It is dynamic.
Straightness detection mechanism includes sliding block 3, first support bar 4, second support bar 5 and amesdial 6, and the sliding of sliding block 3 is set
In on sliding rail 2, one end of first support bar 4 is connect with sliding block 3, the other end of one end and first support bar 4 of second support bar 5
It connects and angle between the two is adjustable, the table bar of amesdial 6 is connect with the other end of second support bar 5, and the table of amesdial 6
Bar tilts, and the contact end of amesdial 6 can be contacted with product 111 is measured.
1 upper surface of supporting block is equipped with V-groove.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
