Description
Technical field
The present invention relates to the measuring appliance in footpath in a kind of nut rolling way and the method for measurement.
Background technology
In automotive steering structure, have and adopt roll structure in the steering nut; And the steering nut endoporus is a spiral rolling track; To the unusual difficulty of the measurement of footpath size in the steering nut raceway, measuring accuracy and efficient are very low in mechanical processing process, so are difficult to judge that whether product process conformance with standard.
Summary of the invention
An object of the present invention is disclose a kind of novel structure in order to solve the existing problem that footpath size in the steering nut raceway is difficult to measure, easy to operate, can be accurately and measure in the steering nut raceway of footpath size in the steering nut raceway directly measuring appliance efficiently.Another object of the present invention is the measuring method that discloses footpath in a kind of steering nut raceway.
In order to realize above-mentioned goal of the invention, the technical scheme below the present invention has adopted:
Footpath measuring appliance in a kind of steering nut raceway; Comprise the body of being with inner chamber, handle, spanner, traveller, spring, meter, fixedly gauge head and movable gauge head, handle is fixedly mounted on the body of band inner chamber, and traveller is arranged in the inner chamber of body; Spanner is fixed on the traveller; The meter position is in the left side of traveller, and the right-hand member of traveller connects body through spring, and traveller is with telescopic spring move left and right in inner chamber; Fixedly gauge head and movable gauge head laterally arrange; Movable gauge head upper end is fixed on the traveller, and fixedly the gauge head upper end is fixed on the body, and fixedly the outside of gauge head and movable gauge head bottom is provided with measure-alike ball respectively; And there is high low head to exposing outside in half of each ball between two balls.
As preferably, the contact of said meter stretches in the inner chamber of body, makes things convenient for contacting of contact and traveller.
As preferably, said meter is a clock gauge, uses extensively, and degree of accuracy is high.
The measuring method in footpath in a kind of steering nut raceway adopts in the above-mentioned steering nut raceway footpath measuring appliance to directly measuring in the steering nut raceway, fixedly the ball diameter of the bottom of gauge head and movable gauge head and nut spiral rolling track consistent size to be measured; Measuring process is following: (1) is that axial distance is adjusted into the half the of nut spiral rolling track pitch to be measured with the high low head value of two balls, according to the middle footpath size of nut rolling way to be measured, meter is proofreaded to zero-bit; (2) spanner is pushed away toward handle orientations, spring is compressed, be fixed on the traveller movable gauge head with traveller is in inner chamber in toward moving right, make the gathering of movable gauge head and fixation side head; (3) movable gauge head and fixation side head are inserted in the tested nut spiral rolling track, unclamp spanner then; (4) spring reset; Movable gauge head is moved to the left the ball of its bottom is contacted with tested nut spiral rolling track; Simultaneously traveller contacts with the meter contact, and the difference of reading when proofreading to zero-bit according to the reading of meter and meter just can be confirmed in the steering nut raceway the directly numerical value of size.
Adopted footpath measuring appliance and measuring method in a kind of steering nut raceway of technique scheme, earlier through fixedly gauge head and movable gauge head settle the standard size again by fixedly gauge head and movable gauge head measure in the nut rolling way footpath through meter embody error information confirm directly to process in the steering nut raceway whether qualified.The advantage of footpath measuring appliance is a novel structure in this steering nut raceway, and is easy for operation, can be accurately and measure in the steering nut raceway footpath size efficiently.
Description of drawings
Fig. 1: the structural representation of the embodiment of the invention.
Embodiment
Do below in conjunction with 1 couple of the present invention of accompanying drawing and to further describe.
Footpath measuring appliance in a kind of steering nut raceway as shown in Figure 1, by the body 6, handle 8, spanner 4, traveller 5, spring 7, meter 3 of band inner chamber, fixedly gauge head 1 and movable gauge head 2 constitute, handle 8 is fixedly mounted on the right-hand member of the body 6 of being with inner chamber.Traveller 5 is arranged in the inner chamber of body 6, and spanner 4 is fixed on the traveller 4, and meter 3 positions are in the left side of traveller 5, and meter 3 is clock gauges, and the contact of clock gauge stretches in the inner chamber 6 of body.The right-hand member of traveller 5 connects bodies 6 through spring 7, and traveller 5 is with spring 7 move left and right in inner chamber of stretching.Fixedly gauge head 1 laterally arranges with movable gauge head 2; Movable gauge head 2 upper ends are fixed on the traveller 5; Fixedly gauge head 1 upper end is fixed on the body 6, and fixedly the outside of gauge head 1 and movable gauge head 2 bottoms is provided with measure-alike ball respectively, and half of each ball is to exposing outside; There is high low head between two balls, fixedly the ball diameter and the nut spiral rolling track consistent size to be measured of the bottom of gauge head 1 and movable gauge head 2.
During use, hold handle, measuring method is following: (1) is that axial distance is adjusted into the half the of nut spiral rolling track 9 pitch H to be measured with the high low head value A of two balls, and the middle footpath size B according to nut rolling way 9 to be measured proofreads meter to zero-bit; (2) spanner 4 is pushed away toward handle 8 directions, spring 7 is compressed, be fixed on the traveller 5 movable gauge head 2 with traveller 5 is in inner chamber in toward moving right, make a movable gauge head 2 and fixation side 1 gathering; (3) with in a movable gauge head 2 and the fixation side tested nut spiral rolling track 9 of 1 insertion, unclamp spanner 4 then; (4) spring 7 resets; Movable gauge head 2 is moved to the left the ball of its bottom is contacted with tested nut spiral rolling track 9; Simultaneously traveller 5 contacts with meter 3 contacts, and the difference of reading when proofreading to zero-bit according to the reading of meter 3 and meter 3 just can be confirmed in the steering nut raceway the directly numerical value of size B.The high low head value A of two balls is adjusted into the half the of nut spiral rolling track 9 pitch H to be measured; Fixedly the ball diameter of the bottom of gauge head 1 and movable gauge head 2 and nut spiral rolling track consistent size to be measured are measured very standard also while half of each ball makes two balls can just in time fall in the nut spiral rolling track of two side to exposing outside.
For example the raceway measurement size B of tested steering nut is Φ 25+0.08, and nut spiral rolling track size is that ball diameter C is Φ 8, and pitch H is 13.5mm.With the high low head value A of two balls is that axial distance is adjusted into the half the of nut spiral rolling track 9 pitch H to be measured; Distance A=6.75mm's, with the endoporus calibrated bolck or the bearing inner race of Φ 25 specifications clock gauge is proofreaded to zero-bit again, press the aforesaid operations procedure; Clock gauge just can demonstrate a reading when traveller 5 contacted with clock gauge 3 contacts; As the reading that demonstrates is+0.03, according to this moment clock gauge reading during with check and correction the difference of reading of clock gauge be 0.03, be Φ 25+0.03 just can confirm the raceway measurement size; Can make things convenient for to obtain footpath size in the nut rolling way accurately, can judge with the standard value comparison whether product processed is qualified.
