Abstract

The utility model relates to an eccentricity sorter of an ABS (Antilock Brake System) brake shaft. A base is provided with two vertical brackets with V-shaped top ends; fork claws at the same side of the two brackets are provided with short shafts, two ends of which are respectively connected with the fork claws; the short shafts are provided with rolling bearings; the bearings on the two short shafts at two sides of the bracket are parallel, and the minimum spacing between the bearings is less than the diameter of the ABS brake shaft; a pressing roll pressing on the ASB brake shaft is arranged above the bracket; a pressing roll shaft is connected with a micro motor output shaft by a speed reducing mechanism; and a sensing measuring head is arranged at the part contacted with an ABS brake shaft head above the bracket and is connected with an electronic part. For the eccentricity sorter, the errors caused by human control are completely avoided, the detected result is accurate and is high in precision, the operation is simple and intuitive and the efficiency is high.

Description

ABS brake axle eccentric throw sorter

Technical field: the utility model relates to a kind of surveying instrument, particularly measures the surveying instrument of brake axle eccentric throw.

Background technology: the ABS brake axle is a used core component on the ABS anti-lock braking system that uses on the automobile, and it mainly acts on is to prevent wheel lock up in braking procedure (promptly stop roll), thus guarantee the driver can also controlling party when braking to.The ABS brake axle is an excentric shaft, if the eccentric throw out-of-size band of ABS brake axle just can't be realized the function of ABS anti-lock braking system will causing fatal accident.So the measurement of ABS brake axle eccentric throw must be accurate.Common measurement instruments is at present: base is provided with two vertical racks that the top is V-shaped, can be equipped with tested ABS brake axle on the support, and spindle nose top is provided with dial gauge.Peak value and minimum point value that dial gauge shows manually one week of rotational workpieces, are with the naked eye read in location, rear end during measurement, through the eccentric throw (deduct minimum point value with the peak value and just be the eccentric throw of ABS brake axle divided by 2) that manually calculates the ABS brake axle.Whether this measuring method is correct in theory, but the people causes the factor of error too many in the process of measuring, steady as the rotation of ABS brake axle, will cause high point value and the low point value got inaccurate as not steady, shake.When reading the numerical value of dial gauge, the ABS brake axle is in fast rotational, and naked eyes read and are easy to occur misreading, mispronouncing.After the error accumulation of each link, just can't embody the actual value of ABS brake axle eccentric throw.And this measuring method efficient is too low, and no mistake proofing is unfavorable for large batch of sorting.

Summary of the invention: the purpose of this utility model is to provide a kind of can eliminate personal error, true, the accurate and high ABS brake axle eccentric throw sorter of detection efficiency of testing result.The utility model mainly is dimerous by machinery and electronics.Wherein, still be provided with two vertical racks that the top is V-shaped on the mechanical part base, the fork pawl of this two stands homonymy is provided with the minor axis that two ends link to each other with them respectively, be provided with rolling bearing on minor axis, it can be one group also can be many groups, and the bearing on two minor axises of support both sides is arranged side by side, gap minimum between them is less than ABS brake axle diameter, the ABS brake axle can be located on two rolling bearings, and not only rollability is good, and rotation is not interrupted.Above support, be provided with pressure roller, the injection moulding pressure roller that preferably friction force is big, this pressure roller shaft links to each other with the micro motor output shaft by reducing gear, and this micro motor can drive pressure roller and rotate, and this pressure roller that can be pressed on the ABS brake axle orders about the rotation of ABS brake axle by friction force.The position that contacts with ABS brake axle spindle nose above support is provided with induction feeler, and it links to each other with electronic section.This electronic section mainly includes amplifier, communication module, terminal board, single-chip microcomputer and display screen, can screen, calculate, store and show the data that induction feeler is collected by this electronic section.

The course of work of the present utility model is as follows substantially: connect with the mains, single-chip microcomputer and micro motor are all started working, the ABS brake axle is placed two groups of rolling bearings on the support and the gap between the pressure roller, micro motor orders about pressure roller and rotates, this pressure roller drives tested ABS brake axle again and slowly rotates, the induction feeler that is located at ABS brake axle spindle nose top is then given single-chip microcomputer with the data transmission that records, this single-chip microcomputer screens the data of collecting, find out eccentric step minimum point of ABS brake axle and pairing two numerical value of peak, single-chip microcomputer calculates with the program formula that weaves then, draw the eccentric throw of ABS brake axle, and this result is transported to display screen on the one hand, be stored in again on the other hand in the SD card of single-chip microcomputer.

The utility model compared with prior art has following advantage:

1, no matter the utility model is the collection of data, the rotation of ABS brake axle, or the output of the last processing of data and result of calculation has all realized robotization, and modernization has avoided the people to control the error that causes fully.

2, the data many (rotate a circle and can collect 720 data) of induction feeler collection, and resolution are at 0.1um, and the result of detection is accurate, precision is high.

3, simple to operate, directly perceived, the efficient height.

4, in single-chip microcomputer, can work out the mistake proofing program, when measured value is undesirable, can report to the police, improve the efficient that detects so greatly.

5, being suitable for different length, the eccentric throw ABS brake axle in 2 millimeters detects.

Description of drawings:

Fig. 1 is that the utility model duty master looks simplified schematic diagram.

Fig. 2 is the cross section simplified schematic diagram of rolling bearing among Fig. 1, pressure roller and ABS brake axle.

Embodiment: the duty master at ABS brake axle eccentric throw sorter shown in Figure 1 looks in the simplified schematic diagram, base 1 is provided with two vertical racks 2 that the top is V-shaped, the fork pawl of this two stands homonymy is provided with the minor axis 3 that two ends link to each other with them respectively, this minor axis is provided with three groups of rolling bearings 4, and the bearing on two minor axises of support both sides is arranged side by side, gap minimum between them is provided with ABS brake axle 5 less than ABS brake axle diameter between this two row bearing.Be provided with the injection moulding pressure roller 6 that is pressed on the ABS brake axle above the support, as shown in Figure 2.Above-mentioned pressure roller shaft links to each other with micro motor 8 output shafts by reducing gear 7.The position that contacts with ABS brake axle spindle nose above support is provided with induction feeler 9, and it links to each other with electronic section 10.This electronic section mainly includes amplifier, communication module, terminal board, single-chip microcomputer and display screen.
