Description
Technical field
The present invention relates to automobile fields of measurement, particularly relate to a kind of rear cover of vehicle measuring instrument and measuring method thereof.
Background technology
The sealing of four two lids of automobile body is one of important process process in automobile installation process, is related to car door and opens
The size of Guan Li, thus affect feel and the comfortableness of switch gate.Wherein rear cover of vehicle seal clearance is even more important, always car
The priority control object of body.Figure 1A shows the structural representation of rear cover of vehicle and sealing strip.Figure 1B is the AA direction of Figure 1A
Generalized section.Fig. 1 C be in Figure 1B rear cover of vehicle in off position under partial cutaway schematic.Fig. 1 D is vehicle in Figure 1B
Bonnet does not has down the partial structurtes schematic diagram of sealing strip.As it can be seen, sealing strip 130 is arranged on rear cover of vehicle
On the seam 120 of 100, under the gap of rear cover of vehicle 100 refers to that case lid 110 is in off position, between seam 120 and case lid 110
Spacing distance d.
The gap size too conference of the spacing distance d between seam 120 and the case lid 110 of rear cover of vehicle 100 causes leaks,
The least meeting of size causes closing forces to become big.The general measuring method of spacing distance d is typically had two kinds: 1) direct method, from vehicle body
Internal measurement, this measuring method, owing to being affected by space, relies on testing staff to measure in piercing rear cover of vehicle, so
Typically the method is not used in the case of no special.Although direct method measurement is wasted time and energy, but its advantage to be measurement error smaller.
2) indirect method of measurement, Fig. 2 A shows that the structural representation using indirect measurement method in prior art, Fig. 2 B show existing
Technology uses the instrumentation plan under indirect measurement method.As it can be seen, plasticine 140 to be embedded stopping of rear cover of vehicle 100
At mouth 120, being then shut off case lid 110, plasticine 140, by case lid 110 crimp, then opens case lid 110, surveys with chi 150
The top of amount plasticine 140 is spacing distance d to the distance of the seam 120 of rear cover of vehicle 100.But by the survey of indirect method
Accuracy of measurement can be changed by the temperature of plasticine 140, change in location, therefore it is difficult to ensure that its certainty of measurement.

Execute the structure schematic diagram of example.Fig. 3 C is the side sectional view of Fig. 3 A.As it can be seen, a kind of rear cover of vehicle clearance meter
300 include measuring instrument body 310 and measure bar 320.Measuring instrument body 310 is provided with a boss 311.At measuring instrument body
Magnet 312 it is installed with on 310.Unrestricted as an example, Magnet 312 is cylindrical, is embedded in measuring instrument body 310.
Measure bar 320 to be made up of magnetic material.Magnetic material can be ferrum, cobalt, nickel or its alloy.Measure bar 320 to be subject to
The suction of Magnet 312 can adsorb on measuring instrument body 310.It is provided with measurement 321 on the top measuring bar 320.
Fig. 4 A shows the structural representation under the use state of one embodiment of the present of invention.Fig. 4 B shows the present invention
An embodiment use state under generalized section.Shown in Fig. 3 A to 3C, measuring instrument body 310 can pass through Magnet
312 absorption are on the seam 120 of rear cover of vehicle 100, and the bottom face of boss 311 is overlapped on the upper limb 121 of seam 120.So, survey
Amount instrument body 310 abuts in the side of seam 120, when the measurement 321 case lid 110 by rear cover of vehicle 100 measuring bar 320
Extruding from top to bottom, measures bar 320 and can do downward movement by relative measurement instrument body 310.When case lid 110 closes with seam 120
During conjunction, measure bar 320 and stop mobile, and adsorbed on measuring instrument body 310 by Magnet 312.According to measuring bar 320 and measuring instrument
Relative position residing for body 310 determines that the seam 120 of rear cover of vehicle 100 arrives the clearance distance d between case lid 110.
Further, with reference to Fig. 3 A and 3B, clearance meter 300 offers chute 313 on measuring instrument body 310.Survey
Gauge rod 320 coordinates with chute 313 makes measurement bar 320 can move in chute 313.When measurement 321 is by rear cover of vehicle 100
Case lid 110 extruding from top to bottom, measures bar 320 and can move in chute 313, i.e. relative measurement instrument body 310 moves.
It is preferred that be provided with nylon block 322 at the top of measurement 321.The purpose arranging nylon block 322 is to prevent from measuring bar
Cause magnetization between 320 and case lid 110, prevent the unlatching of case lid 110 from driving measurement bar 320 due to magnetization after measurement terminates
Act on and move up and then have influence on measurement result.Only touch when case lid 110 times pressure nylon block 322 without directly with
Measure 321 contact.
It is preferred that be provided with length groove on the measuring instrument body 310 and measurement bar 320 of clearance meter 300.With reference to figure
3B, can determine that according to the final position of length groove the seam 120 of rear cover of vehicle 100 arrives the clearance gap between case lid 110
From d.
Present invention also offers a kind of rear cover of vehicle gap measuring method, apply clearance meter 300 as above.Ginseng
Examining Fig. 4 A, 4B and Fig. 5, the method comprises the following steps:
Step 501, opens the case lid 110 of rear cover of vehicle 100.
Step 502, abuts in the side of the seam 120 of rear cover of vehicle 100 by the measuring instrument body 310 of clearance meter 300
Face, makes the bottom face of boss 311 be overlapped on the upper limb 121 of seam 120.
Step 503, promotes and measures bar 320, make to keep between measurement 321 and boss 311 setpoint distance.This setting away from
From the clearance distance d that should be greater than rear cover of vehicle 100.
Step 504, close rear cover of vehicle 100.When measure 321 by rear cover of vehicle 100 case lid 110 from top to bottom
Extruding, measuring bar 320 can move down by relative measurement instrument body 310, and measurement 321 is gradually drawn close to boss 311.Work as case lid
110 when closing with seam 120, measures bar 320 and stops mobile, and is adsorbed on measuring instrument body 310 by Magnet 312.According to survey
Relative position residing for gauge rod 320 and measuring instrument body 310 determines that the seam 120 of rear cover of vehicle 100 arrives between case lid 110
Clearance distance d.
It is preferred that measuring instrument body 310 and measurement bar 320 are provided with length groove, after the rear cover of vehicle 100 that closes, root
Measurement result is read according to this length groove.
It is preferred that setpoint distance in step 503 is 4～10mm.
It is attracting with magnetic material that the rear cover of vehicle clearance meter of present invention offer and measuring method make full use of Magnet
Principle, is fixed on the main body of clearance meter on seam by Magnet and boss.When being affected by external force, measuring bar can be relatively
Main body moves, and once loses external force, measures bar and is held by Magnet fixing.Compared with prior art, easy to operate, not by environment temperature
Degree impact, low cost and measurement error are little.Here the error existed is exactly the error in reading of human eye, typically within 0.2mm.
Those skilled in the art can be obvious, the above-mentioned exemplary embodiment of the present invention can be carried out various modifications and variations and
Without departing from the spirit and scope of the present invention.Accordingly, it is intended to make the present invention cover at appended claims and equivalence techniques thereof
Modifications of the present invention in aspects and modification.
