Abstract
The utility model is a testing tool used for guaranteeing measuring precision of a workpiece. The testing tool comprises a pedestal. The pedestal is equipped with a reference seat which is used for fixing a to-be-tested workpiece and comprises a reference surface used for proofreading dimension of the to-be-tested workpiece. The pedestal is also provided with a block-up block. When a user is using the testing device, through difference values measured by all detection tools, the difference values of the detection tools are compensated via the block-up block to allow height from a surface of the block-up block to a center point on a surface of the reference seat to be equal, and then an indicating gauge is utilized to measure whether the height of the workpiece is qualified.
Description
Technical field
The utility model relates to a kind of cubing, especially a kind of cubing that is used to guarantee the workpiece calibration precision.
Background technology
In the present a lot of parts processing, often need detect the precision of the finished product workpiece after processing, comprise height, angle or the like, this just need use special testing tool, and need use different types of testing tool.
Yet the simple workpiece calibration height of part only need be used once the cover testing tool passable, but for those comparatively complicated workpiece, for example surface of the work has curved surface, when the measuring workpieces height, need be equipped with the testing tool of quite a few covers like this.Such as wiper, it comprises several curved surfaces, it is all variant when measuring, respectively to overlap the data that testing tool records; Be difficult to detect, this certainly will need very high making precision to guarantee that testing tool all is the same to want to record fully qualified size, still; In the actual fabrication process, it is very difficult making the identical testing tool of quite a few covers, and this has just directly influenced the qualification rate of product; The scrappage of product improves, and has delayed the trial production cycle of product and has increased production cost.
Summary of the invention
Deficiency to prior art; The utility model provides a kind of cubing that is used to guarantee the workpiece calibration precision; This device utilizes in use and respectively overlaps the difference that testing tool records; Through the difference of bed hedgehopping block compensation testing tool, make that the height of the bed hedgehopping piece surface mid point to the reference seat surface is identical, whether last to record the height of workpiece with dial gauge more qualified.
For solving technique scheme, the utility model provides following technical proposals to be able to solve.
A kind of cubing that is used to guarantee the workpiece calibration precision comprises base, and said base is provided with the reference seat that is used for fixing measured workpiece, and said reference seat comprises the reference field that is used to proofread the measured workpiece size, also is provided with the bed hedgehopping piece on the said base.
In the technique scheme, also be provided with limit stick on the said base, the place of leaning of said limit stick parallels with a side of said reference seat.
In the technique scheme, be provided with in the said reference seat and hold out against screw, register pin, said holding out against between screw and the said register pin is provided with spring.
In the technique scheme, said base is provided with pressing head seat, and said pressing head seat comprises pressure head, depression bar, and the central axis of said pressure head and the central axis of said reference seat are on same straight line.
Compare with prior art, the beneficial effect of the utility model is:
1, compensate the difference of respectively overlapping between the testing tool through use bed hedgehopping piece, thereby the testing tool that has solved making has improved the qualification rate of workpiece greatly because of the different problem that causes workpiece to be scrapped of the value that detects.
2, reduced the time cost of making testing tool.
3, can not prolong the trial production cycle of product because of the cubing reason.
Description of drawings
Fig. 1 is used to guarantee the structural representation of the cubing of workpiece calibration precision for the utility model is a kind of.
Fig. 2 is used for guaranteeing the cut-open view of the cubing reference seat of workpiece calibration precision for the utility model is a kind of.
Fig. 3 is used for guaranteeing the enlarged drawing at the cubing I place of workpiece calibration precision for the utility model is a kind of.
Embodiment
Be used to guarantee that to the utility model is a kind of the cubing of workpiece calibration precision does further explain below in conjunction with description of drawings.
Referring to Fig. 1 ~ Fig. 3, a kind of cubing that is used to guarantee the workpiece calibration precision comprises base 1; Said base 1 is provided with reference seat 3, the pressing head seat 10 that is used for fixing measured workpiece 2; And said reference seat 3 comprises the reference field 4 that is used to proofread measured workpiece 2 sizes, and said pressing head seat 10 comprises pressure head 11, depression bar 12, and the central axis of the central axis of said pressure head 11 and said reference seat 3 is on same straight line; One end of measured workpiece 2 is fixed on the said reference seat 3; Pull depression bar 12 then and make pressure head 11 that measured workpiece 2 one ends are compressed, still common can produce skew to the Work-sheet pressing workpiece, can not well locate.
See Fig. 2 for details,, be provided with in the said reference seat 3 and hold out against screw 7, register pin 8 as preferably; One end of said register pin 8 is tapered, and said holding out against between screw 7 and the said register pin 8 is provided with spring 9, when workpiece squints; Under the effect of spring 9; Make register pin 8 get back to original position, then with pressure head 11 with Work-sheet pressing, so can arrive good the location.
Then, also be provided with bed hedgehopping piece 5 on the said base 1, through using bed hedgehopping piece 5, compensate the difference of respectively overlapping between the testing tool, thereby confirm a fixing value, this is worth the standard value of workpiece qualified size just.
The workman detects workpiece for ease, as preferably, also is provided with limit stick 6 on the said base 1, and the place of leaning of said limit stick 6 parallels with a side of said reference seat 3.One end of measured workpiece 2 is fixed on the said reference seat 3, and the other end then leans on the surface of limit stick 6, and workpiece can not shaken when measuring like this, is convenient for measuring.
The wiper of giving an example is below made the work rationale to the design: wiper comprises through hole 13, connecting link, joint 14, and the cross section of said connecting link is an arc, and the surface of joint 14 also is a curved surface; It all is different when measuring height, respectively overlapping the numerical value that testing tool measures, and at this moment, reaches qualified for energy measurement goes out the wiper height; At first through hole 13 is inserted on the reference seat 3, pulls depression bar 12 then, and 11 pairs of wipers of pressure head are compressed; Measure the height of joint 14 then, after measuring numerical value, the difference between this numerical value is compensated through bed hedgehopping piece 5; Make that the upper surface of bed hedgehopping piece 5 is consistent to the height on the reference field 4; At this moment again with the height of testing tool and bed hedgehopping piece 5 combination measurement wipers, as long as the numerical value of measuring can reach specified standard, product is exactly qualified; If do not reach standard, product is exactly underproof so.
Description through above-mentioned principle; Use bed hedgehopping piece 5 to compensate the difference of respectively overlapping between the testing tool; Make that bed hedgehopping piece 5 surfaces are identical to the height of reference seat 3 surperficial mid points; Thereby the testing tool that has solved making has improved the qualification rate of workpiece greatly because of the different problem that causes workpiece to be scrapped of the value that detects.
