Abstract
The utility model discloses a groove width measuring tool for hot-rolled forklift portal frame channel steel. The groove width measuring tool is characterized by comprising two measuring bodies corresponding to groove width, wherein the width of one of the two measuring bodies is an upper limit of the groove width adding the dimensional tolerance; and the width of the other of the two measuring bodies is an upper limit of the groove width subtracting from the dimensional tolerance. According to the measuring tool, the groove width of the products can be rapidly measured; whether the groove width is qualified is rapidly judged; and moreover, the measuring time and the measuring error are reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of solution in production hot rolling forklift door frame channel-section steel process, is difficult to measure the survey instrument of the problem of groove width, is specially a kind of hot rolling forklift door frame channel-section steel groove width survey instrument.
Background technology.
The fork truck tackling system is very high to the intensity and the dimensional requirement of forklift door frame channel-section steel.Many rollers are arranged in the middle of the inside groove of forklift door frame channel-section steel, and for guaranteeing that pallet fork steadily promotes, the groove width dimensional accuracy must at first guarantee.In use, this size must be accurately do not measured,, the safe operation of whole forklift door frame can be guaranteed as long as groove width is controlled in the tolerance.Therefore, to pay close attention to forklift door frame channel-section steel groove width in process of production.But when in actual production, finding to use this size of vernier caliper measurement, Measuring Time is long and maloperation very easily occurs, causes measurement and judges that efficient is lower, influences production efficiency.
Summary of the invention
In order to solve in the hot rolling forklift door frame channel-section steel production run, the problem of difficulty is measured and judged to groove width, and the utility model provides a kind of hot rolling forklift door frame channel-section steel groove width survey instrument, but has the whether qualified advantage of quick test.
For achieving the above object the following technological means of the employing of the utility model:
A kind of hot rolling forklift door frame channel-section steel groove width survey instrument; Comprise two measurement bodies corresponding with groove width; Two width of measuring a measurement body in the body are groove width and dimensional tolerence upper limit sum, and another width of measuring body is groove width and dimensional tolerence lower limit sum.
Further, the thickness of described two measurement bodies is 0.5-10mm.
Use two 0.5～10mm groove widths of line cutting mode preparation to measure plate.
Two width of measuring a measurement body in the body are groove width and dimensional tolerence upper limit sum, and another width of measuring body is groove width and dimensional tolerence lower limit sum.
The beneficial effect of the utility model shows:
Tradition is used vernier caliper measurement and is judged that the method for hot rolling forklift door frame channel-section steel groove width compares at present together, and visible, the characteristics of the utility model are:
1. measuring process need not used high-acruracy survey instruments such as vernier caliper, is convenient to use in the commercial process.
2. measuring method is simple, can judge fast whether the product groove width is qualified.
3. groove width is measured board size precision height, and is not yielding, is easy to carry about with one, and is applicable to outdoor and field survey.
Description of drawings
In order to be illustrated more clearly in the application embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment that put down in writing among the application, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings;
Fig. 1 is for measuring the plate structure synoptic diagram;
Fig. 2 is for using the measurement and the decision process synoptic diagram of this method;
Fig. 3 is the channel-section steel structural representation.
Embodiment
The following correlation technique content of not addressing all can adopt or use for reference prior art.
In order to make those skilled in the art person understand the technical scheme among the application better; To combine the accompanying drawing among the application embodiment below; Technical scheme among the application embodiment is carried out clear, intactly description; Obviously, described embodiment only is the application's part embodiment, rather than whole embodiment.Based on the embodiment among the application, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the application's protection.
As shown in Figure 1, a kind of hot rolling forklift door frame channel-section steel groove width survey instrument comprises two groove widths measurement plates, A plate and B plate, and it is corresponding with 22# door frame channel-section steel inside groove to measure board size, and door frame channel-section steel inside groove is seen Fig. 3.
Groove width is measured plate and is made:
Wherein the groove width standard value is 152.75mm, and tolerance is ± 0.75mm.On be limited to+0.75mm, be limited to-0.75mm down.
The A board size is 152.75+0.75=153.00 (mm);
The B board size is 152.75-0.75=152.00 (mm);
A plate and B sheet thickness dimension are 2mm.
Groove width is measured and decision process:
(1) with the A plate perpendicular to tested channel-section steel, as putting into tested channel-section steel inside groove, be wider than requirement in then, judge that this channel-section steel is a unacceptable product.
(2) with the B plate perpendicular to tested channel-section steel, as putting into tested channel-section steel inside groove, then inner width judges that less than requiring this channel-section steel is a unacceptable product.
(3) with A plate and B plate all perpendicular to tested channel-section steel, can not put into tested channel-section steel inside groove like the A plate, and the B plate can put into tested channel-section steel inside groove, then inner width meets the demands, and judges that this channel-section steel is certified products.
(4) groove width measurement and decision flowchart are seen Fig. 2.
The above only is the application's a preferred implementation, makes those skilled in the art can understand or realize the application.Multiple modification to these embodiment will be conspicuous to one skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the application or scope in other embodiments among this paper.Therefore, the application will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
Claims (2)
