Background technology
Automobile luggage racks refers to that being arranged on roof is easy to the support of frenulum large piece article, is used for loading heavy luggage, the large piece article such as boat, water wing, equipped with the most convenient during the automobile out on tours of roof-rack, can meet people's difference demand.Automobile luggage racks generally includes stretch bending bar and base, stretch bending bar constitutes the automobile luggage racks of band certain radian with base assembling, such luggage carrier is the most attractive in appearance, and it is high with automobile fitness, but automobile luggage racks produces and there is also following deficiency with detection process at present: (1) conventional vehicle luggage carrier radian at present detects, first automobile luggage racks is placed on the cubing body coordinated with automobile luggage racks radian, then observe the gap size between automobile luggage racks and cubing body by visual method, differentiate automobile luggage racks radian the most qualified.(2) conventional vehicle luggage carrier radian detection at present, first automobile luggage racks is placed on the cubing body coordinated with automobile luggage racks radian, observe the gap size between automobile luggage racks and cubing body, and fill in gap by fork clip, record gap size, thus judge that automobile luggage racks radian is the most qualified.But it is big that such detection method not only detects error, and detection efficiency is low, is substantially reduced the production efficiency of automobile luggage racks.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art existence, and provides a kind of stretch bending bar radian detecting device detecting simple, detection efficiency is high a kind of automobile luggage racks.
The purpose of this utility model is realized in.
A kind of stretch bending bar radian detecting device of automobile luggage racks, including pendulum cubing body, base plate and the dial gauge placed for stretch bending bar, cubing body and dial gauge are arranged on base plate, described dial gauge includes table body, sleeve and gauge rod, table body and sleeve connection, gauge rod stretches in table body along sleeve, described cubing body is provided with measurement through hole, cubing body side contacts with table body, cubing body opposite side constitutes stretch bending bar placement area, and gauge rod end stretches in stretch bending bar placement area along the measurement through hole of cubing body.When stretch bending bar is placed on cubing body, the outer wall of stretch bending bar compresses gauge rod, in gauge rod retraction table body, numerical value is measured in table body display simultaneously, workman only needs to observe the measurement numerical value of dial gauge, judge whether in range of error, the radian detection of stretch bending bar can be completed, be greatly improved the detection efficiency of stretch bending bar.
Technique scheme also can be made to the following further improve.
As more specifically scheme, being provided with keeper between described dial gauge and cubing body, described keeper is fixed on base plate, keeper is provided with holding through hole, holding through hole is through with measurement through hole, and sleeve inserts in holding through hole, it is achieved dial gauge positions and is securely mounted on keeper.By sleeve holding in through hole, it is achieved dial gauge positions and firmly installs, prevent measurement process dial gauge from loosening, cause measurement error.
As more specifically scheme, described gauge rod along holding through hole, measure through hole insert along stretch bending bar placement area with stretch bending bar wall contacts.
As concrete scheme, described cubing body curving certain radian, constitute the automobile stretch bending bar placement area that the radian of bending mates with the radian of stretch bending bar.The automobile stretch bending bar placement area mated with luggage carrier radian by setting, is made luggage carrier placement location more suitable, improves measurement effect.
As concrete scheme, described dial gauge, quantity and the measurement number of openings one_to_one corresponding of keeper.By arranging multiple measurement through hole and multiple dial gauge, more fully detect the radian of stretch bending bar, be greatly improved Detection results, improve yield rate of dispatching from the factory.
As concrete scheme, described measurement through hole has five, measures through hole for five and is averagely arranged on cubing body.
As concrete scheme, also include that handle, described handle are fixed in base plate both sides.By arranging handle, carrying and put conveniently, the stretch bending bar improving luggage carrier detects the practical of device.
As more specifically scheme, described stretch bending bar is stretch bending aluminum bar.By using the stretch bending bar of aluminium material, not only add bending in man-hour easily, and anticorrosion can keep attractive in appearance.
The beneficial effects of the utility model are as follows
Stretch bending bar is placed in the automobile stretch bending bar placement area of cubing body by this utility model, stretch bending bar is by compression gauge rod and is pushed by gauge rod in table body, numerical value is measured in table body display simultaneously, workman only needs to observe the measurement numerical value of dial gauge, i.e. can determine whether to measure numeral whether in range of error, the radian detection of stretch bending bar can be completed, be greatly improved the detection efficiency of stretch bending bar.
The automobile stretch bending bar placement area bending certain radian of this utility model cubing body side, and the radian bent coordinates with the radian of stretch bending bar, and stretch bending bar can be close in stretch bending bar placement area, is greatly improved the precision of detection and the efficiency of detection.
Embodiment, in conjunction with Fig. 1 to Fig. 6, a kind of stretch bending bar radian detecting device of automobile luggage racks, including cubing body 1, base plate 2, dial gauge 3, keeper 4 and the handle 5 placed for stretch bending aluminum bar 50, described handle 5 is fixed in base plate 2 both sides, and cubing body 1 arranges on a base plate 2, and cubing body 1 is provided with five measurement through holes 6 being evenly arranged, cubing body 1 side is connected with dial gauge 3, and cubing body 1 opposite side inwall is bent into the stretch bending bar placement area 7 mated with stretch bending aluminum bar 50 radian.
Described keeper 4 is fixed on a base plate 2 and lays respectively at each measurement through hole 6 side, holding through hole 8 is had on keeper 4, described dial gauge 3 includes table body 9, sleeve 10 and gauge rod 11, table body 9 is connected with sleeve 10, sleeve 10 inserts in holding through hole 8, dial gauge 3 by location, be securedly mounted on keeper 4, described gauge rod 11 one end contacts with table body 9 in stretching into sleeve 10, the other end inserts the interior wall contacts with stretch bending aluminum bar 50 in stretch bending bar placement area 7, for measuring the crooked radian of stretch bending aluminum bar 50 along holding through hole 8, measurement through hole 6.
Operation principle
Luggage carrier with certain radian is placed in the stretch bending bar placement area 7 mated with stretch bending aluminum bar 50 radian by workman, stretch bending bar outer wall extruding gauge rod 11 when putting, in forcing gauge rod 11 retraction table body 9, when automobile luggage racks is put into stretch bending bar placement area 7 completely and is close to the inwall of cubing body 1, dial gauge 3 is measured the gap between cubing body 1 inwall and stretch bending bar and reads radian value, then workman observes the reading of each dial gauge 3, the error amount set is produced according to stretch bending bar, if dial gauge 3 reading is in ranges of error values, it is qualified products, if dial gauge 3 reading exceeds range of error, it it is substandard product, compare conventionally employed fork clip and fill in gap, read radian value, it is greatly improved detection efficiency and detection accuracy.
