Description
Technical field:
The present invention relates to measurement mechanism, more particularly a kind of measurer for thickness.
Background technology:
Automobile drive axle is the important big assembly of automobile, it is positioned at the end of automotive transmission, it is to increase by transmission shaft or the direct torque of being transmitted by variator that its basic training is used, it is distributed to the left and right driving wheel, and make the left and right driving wheel have the desired differential function of running car kinematics; Simultaneously, bearing loading and ground give through suspension through wheel, vehicle frame or monocoque body on the fully loaded spring of automobile vertical force, longitudinal force, transverse force and moment thereof, and shock load.In general vehicle structure, drive axle comprises parts such as the gearing of main reducing gear, differential mechanism, drive wheels and axle housing.Wherein the effect of main reducing gear is that power with wheel box further slows down and changes its direction of transfer and passes to left and right wheel, and the effect of differential mechanism is to satisfy driving wheels inharmonic requirement on the kinematics of travelling, the whole automobile drive axle performance of influence that their assembly quality is direct.
The restricted factor of the assembly quality of drive axle main reducing gear is a lot, and one of them important factor is whether master, passive spiral bevel gear pair mesh well.In order to make gear pair engagement good, when the assembling main reducing gear, one, support stiffness that must control drive bevel gear axle, i.e. the pretightning force of a pair of taper roll bearing of drive bevel gear axle is supported in control; Two, must control the driving gear back of tooth and equal design load, promptly control the installation site of drive gear shaft assembly and reducer shell to the distance of driven gear axis.For the control requirement of assembling above, generally be the method that adopts plus-minus adjustment pad between a pair of taper roll bearing of supporting drive bevel gear axle and between bearing seat flange and housing.Therefore, correctly selecting used spacer thickness, is the key that improves the main reducing gear assembly quality.
For the pad of different size kind, people are to use instruments such as vernier caliper, milscale to carry out hand dipping before this, and still, because the influence of the burr of pad itself, anti-limit, factor such as in uneven thickness, often measuring error is bigger.
Summary of the invention:
Technical matters to be solved by this invention is to avoid above-mentioned existing in prior technology weak point, and a kind of spacer thickness measuring instrument is provided, with accurate measurement spacer thickness.
The technical scheme that technical solution problem of the present invention is adopted is:
Architectural feature of the present invention is that clamping plate shaped measuring head is set, described clamping plate shaped measuring head is made of bottom measuring table and the measuring pressure plate that is positioned at the measuring table top, pad is placed between measuring table and the measuring pressure plate, described measuring table is for moving axially member, move the axial setting of measuring staff with the axle of the gauge head of clock gauge interlock along measuring pressure plate, it is sensitive face with the measuring table that described axle moves measuring staff, and its bottom end face stretches to measuring table.
Among the present invention, moving axially of measuring table makes the clock gauge gauge head produce moving axially with respect to measuring pressure plate.The concrete relative measurement principle that adopts, when not placing tested pad, the original state of the fit-state of measuring table and measuring pressure plate for measuring, with this moment axle move measuring staff and be reflected in displacement on the clock gauge gauge head as with reference to amount; During measurement, between measuring table and measuring pressure plate, place pad to be measured, with cylinder measuring table being risen makes it and measuring pressure plate is fitted, with this moment axle move displacement and the reference quantity that measuring staff is reflected on the clock gauge gauge head and compare, institute's value is exactly tested spacer thickness.Measuring table move axially the pneumatic control mode that adopts, not only convenient but can guarantee to fit the time suitable pressure eliminate gap and burr between the pad, simulated actual working state.
Compared with the prior art, the present invention has following beneficial effect:
The present invention is simple and practical, measuring accuracy height, the repeatable accuracy height of Ce Lianging repeatedly, efficiency of measurement height.
The drawing explanation:
Accompanying drawing is a structural representation of the present invention.
Number in the figure: 1 rises adds carrier gas cylinder, 2 measuring machine table tops, 3 cylinder mounting plates, 4 and holds up slide-bar base plates, 5 and hold up slide-bar orienting sleeves, 6 and hold up slide-bars, 7 spherical ball, 8 measuring tables, 9 measuring pressure plates, 10 and measure pressure head mount pads, 11 gauge head slip rings, 12 and move measuring staff, 13 clock gauges resilient sleeve, 14 clock gauges, 15 guard rings, 16 gauge head springs, 17 liang of position four-way valves, 18 measuring table elasticity holder heads, 19 a measuring table holder spring are installed.
By the following examples, in conjunction with the accompanying drawings the present invention is further described:
Embodiment:
Referring to accompanying drawing, present embodiment is provided with clamping plate shaped measuring head, clamping plate shaped measuring head is made of bottom measuring table 8 and the measuring pressure plate 9 that is positioned at measuring table 8 tops, pad is placed between measuring table 8 and the measuring pressure plate 9, measuring table 8 is for moving axially member, axle moves the axial setting of measuring staff 12 along measuring pressure plate 9, the gauge head of clock gauge 14 is butted on the top end face that axle moves measuring staff 12, the bottom end face that axle moves measuring staff 12 stretches to measuring table 8, and can touch measuring table 8, it is to be sensitive face with measuring table 8 that axle moves measuring staff 12.
Shown in the figure, in the present embodiment, the employing pneumatic control mode that moves axially of measuring table 8, being provided with rises adds carrier gas cylinder 1, rise and add carrier gas cylinder 1 is installed in survey machine amount table top 2 by cylinder mounting plate 3 below, be provided with on measuring machine table top 2 and hold up slide-bar orienting sleeve 5, the picking-up slide-bar 6 that is added carrier gas cylinder 1 driving by rising is arranged in orienting sleeve 5.
