Abstract
The utility model relates to a groove pitch detecting tool, which comprises a mandrel and an elastic sleeve with an R end. The elastic sleeve with the R end is mounted in the mandrel 1, the intersection point of the circumference and the end face of the mandrel is a measured point of a measured cone, the elastic sleeve with the R end is connected with a dial indicator through an indicator seat 3, and the distance from the R center of the elastic sleeve with the R end to the circumference and the end face of the mandrel is adjusted by a nut arranged between the indicator seat and the elastic sleeve with the R end. The groove pitch detecting tool has the advantages that the groove pitch detecting tool is simple and practical, measuring time is short, a workpiece can be measured only in a few seconds, and more importantly, a part can be detected in an online manner during machining.
Description
Technical field
The utility model relates to a kind of cubing of endoporus slot pitch, relates in particular on the inner cone certain any ideal plane a kind of slot pitch cubing of distance between the R groove center in the endoporus.
Background technology
The cylinder barrel body of automobile steering device housing assembly is steel pipe moulding is to connect through the cone that has angle in the junction of big small end through stretching enlarging that the big end endoporus of enlarging has cut the R groove.Slot pitch belongs to the key property size, needs key monitoring, so must high frequency time effectively measure on the inner cone certain any plane distance between the R groove in the big end endoporus.Because certain any plane is an ideal dimensions plane on the inner cone, and certain degree of difficulty is arranged during measurement, the center that needs instrumentation and find out ideal dimensions plane and R groove through calculating is energy measurement, and needs three directions of 120 ° of measurements of rotation.General detection mode is to measure through contourgraph, and its Measuring Time is long, and truly reflection plane is to the distance of face, and data as a reference, the high volume production process of auto industry need appliance special for detecting to monitor to have suffered production run.For solving the practical problems that slot pitch is measured, need a kind of simple and practical cubing and substitute apparatus measures.
Summary of the invention
The utility model technical issues that need to address have provided a kind of slot pitch cubing, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is realized through following technical scheme:
The utility model comprises: mandrel; Also comprise: the resilient sleeve that has the R end; The resilient sleeve of the described R of having end is packed on the mandrel 1; The intersection point of said axle diameter and end face is the measurement point on the tested cone; The said resilient sleeve that has the R end connects dial gauge through gauge stand 3; The R center of the resilient sleeve of the said R of having end is adjusted through the nut that is placed in gauge stand and have between the resilient sleeve of R end to the axle diameter end face distance.
Compared with prior art, the beneficial effect of the utility model is: simple and practical, Measuring Time is short, only needs can accomplish several seconds the measurement of a workpiece; The more important thing is can online detection when the process of part.
Description of drawings
Fig. 1 be measured workpiece structural representation.
Fig. 2 is the structural representation of the calibrated bolck of the utility model simulation workpiece.
Fig. 3 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Visible by Fig. 3: the utility model comprises: mandrel 1; Also comprise: the resilient sleeve 2 that has the R end; The resilient sleeve 2 of the described R of having end is packed on the mandrel 1; The intersection point of said mandrel 1 diameter and end face is the measurement point on the tested cone; The said resilient sleeve 2 that has the R end connects dial gauge 5 through gauge stand 3; The R center of the resilient sleeve 2 of the said R of having end is adjusted through the nut 4 that is placed in gauge stand 3 and have between the resilient sleeve 2 of R end to mandrel 1 diameter end face distance.
As shown in Figure 1, the detection position A of measured workpiece, certain a bit is actually a conic section through this point on the inner cone, to the distance of R groove center.
As shown in Figure 2, the calibrated bolck of simulation workpiece is made up of two parts, and through revising part 10 or part 20, the end face that reaches part 10 is of a size of the desired slot pitch standard size of workpiece to the R groove center of part 20.
Adopt the detection method of the utility model: at first the slot pitch cubing is inserted in the calibrated bolck, the R end that has the resilient sleeve 4 of R end pushes in the R groove of calibrated bolck, and adjustment dial gauge 5, the reading that makes dial gauge 5 are zero.With the cubing measuring workpieces of adjusting, it is poor that the reading error of dial gauge is the physical size of workpiece then.
In sum, the utility model slot pitch cubing simple in structure, element is few, reduces cost, and is easy to operate, can online detection when the work piece production process.
