Abstract
The utility model pertains to the technical field of powder metallurgy, in particular to an external span length detector for a gear hub of an automobile speed changing box. The technical scheme is as follows: the external span length detector for the gear hub comprises a dial gauge, a base plate and a support plate, wherein the support plate is fixedly connected with the back surface of the base plate, the dial gauge is fixedly connected with the base plate by a gauge clip positioned at the upper part of the base plate, a spindle which is connected with the base plate vertically and fixedly is arranged in the middle of the base plate, and the lower part of the base plate is provided with a measuring rod which is connected with the base plate vertically and fixedly. The detector has simple structure, is manufactured easily, and can measure the span length conveniently and accurately.
Description
Technical field
The utility model belongs to powder metallurgy manufacturing technology field, relates in particular to a kind of automobile case tooth hub that hastens and strides excellent device for detecting distance outward.
Background technology
PM technique is a kind of novel process, be to produce metal powder (adding or do not add non-metal powder), implement to be shaped and sintering, make the job operation of material or goods, powder metallurgy has unique chemical and forms and machinery, physical property, and these performances are can't obtain with traditional casting method, and the utilization PM technique can directly be made porous, half fine and close or full dense material and goods.The more and more wider model of the utilization of powdered metal parts on automobile, the tooth hub is a strength member in the automobile gearbox, because the accuracy requirement of tooth hub is very high, the size tolerance requirements of striding excellent distance outward is very little, so in order to control product quality, improved the check frequency, striden the size of excellent distance in the prior art with miking outward, but owing to divide the size of measuring three directions for three times respectively, so detection speed is very slow.
Summary of the invention
The purpose of this utility model is, overcomes the deficiencies in the prior art, provides a kind of tooth hub to stride excellent device for detecting distance outward, and this pick-up unit is simple in structure, makes easily, and it is convenient, accurate to measure.
For solving the problems of the technologies described above, the technical solution of the utility model is: the tooth hub is striden excellent device for detecting distance outward, this device comprises dial gauge, bedplate and back up pad, described back up pad is fixedlyed connected with the back side of bedplate, described dial gauge is fixedlyed connected with bedplate by the table folder that is positioned at bedplate top, at the middle part of bedplate the mandrel that is connected with the bedplate vertical fixing is arranged, the length bar that is connected with the bedplate vertical fixing is arranged in the bottom of bedplate.The size of the size of mandrel and tooth hub female spline path is suitable, generally stays gap 0.05-0.1mm, and mandrel and bedplate are welding, and length bar and end seat are welding.The principle of work of dial gauge is that the small straight line of measuring staff that measured size causes is moved, and amplifies through gear drive, become to refer to the rotation of meter on index dial, thus the size of reading measured size.When measuring, the tooth hub is placed between the amount ball of length bar on the bedplate and Centigrade scale, mandrel is arranged in the hole of tooth hub, must out stride the dimensional tolerence of excellent distance by the data of dial gauge.
The utility model has beneficial effect to be: the tooth hub is striden excellent device for detecting distance outward, this device comprises dial gauge, bedplate and back up pad, described back up pad is fixedlyed connected with the back side of bedplate, described dial gauge is fixedlyed connected with bedplate by the table folder that is positioned at bedplate top, at the middle part of bedplate the mandrel that is connected with the bedplate vertical fixing is arranged, the length bar that is connected with the bedplate vertical fixing is arranged in the bottom of bedplate.This installs simplicity of design, and it is convenient to measure, and has improved measuring speed, has saved the time, and has improved measuring accuracy.Originally each the class everyone can only examine 200, use this device now, can bring up to 480.
