Fig. 2 is the side view of Instrument for Straightness shown in Fig. 1;
Fig. 3 is the using state schematic diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As depicted in figs. 1 and 2, the Instrument for Straightness in the present embodiment comprises is that the first sway brace 1 of splayed distribution and the upper end of the second sway brace 2, first sway brace 1 are connected by transverse arm 3 with the upper end of the second sway brace 2 mutually.The second surveyingpin 51 that first sway brace 1 is provided with the first phasing meter 4 of pairing use and the first surveyingpin 41 of the second phasing meter 5, first phasing meter 4 and the second phasing meter 5 is mutually mutually vertical.
Particularly, first phasing meter 4 is arranged on the lateral wall of the first sway brace 1, first surveyingpin 41 parallels with the lateral wall of the first sway brace 1 and protruding in the first sway brace 1, first surveyingpin 41 to stretch out direction consistent with the length direction of the first sway brace 1, and the length direction of the first surveyingpin 41 and the rotating direction of rolling body perpendicular.The lateral wall of the first sway brace 1 is provided with mounting bracket 6, in the present embodiment, this mounting bracket 6 is right angle rack, the bottom of this right angle rack is fixed on the lateral wall of the first sway brace 1, the top of this right angle rack is protruding in the first sway brace 1, and this right angle rack to stretch out direction consistent with the length direction of the first sway brace 1, the top that second phasing meter 5 is arranged on right angle rack stretches out in the position of the first sway brace 1, and the second surveyingpin 51 is perpendicular to the lateral wall of the first sway brace 1.
In addition, the second surveyingpin 51 can be in same plane with the first surveyingpin 41 also can be in Different Plane, if in conplane situation, then the syringe needle extended line of the second surveyingpin 51 drops on the syringe needle extended line of the first surveyingpin 41.
All rolling body is installed at the middle part of the first sway brace 1 and the both sides of lower end, all rolling body is installed at the middle part of the second sway brace 2 and the both sides of lower end, in the present embodiment, rolling body adopts roller 7, roller 7 is arranged on rolling wheel support frame 8, and rolling wheel support frame 8 is fixed on the first sway brace 1 and the second sway brace 2.Certainly, rolling body also can adopt roller or bearing, and correspondingly, roller is fixed on the first sway brace and the second sway brace by roller support frame, and bearing is fixed on the first sway brace and the second sway brace by bearing supporting frame.
As shown in Figure 3, be placed on the guided way 91 of straight-bar machines frame 9 during the work of this Instrument for Straightness, the line slideway 10 of linearity to be measured is fixed on the both sides of straight-bar machines frame 9 and parallels with guided way 91.Wherein, the accuracy requirement that the linearity demand fulfillment of guided way 91 is certain, while Instrument for Straightness is moved around along guided way 91 by roller 7, the first surveyingpin 41 of the first phasing meter 4 and the second surveyingpin 51 of the second phasing meter 5 contact with two adjacent surfaces of the line slideway 10 of linearity to be measured respectively.In measuring instrument moving process, change by the number of degrees of the first phasing meter 4 and the second phasing meter 5 linearity just can understanding line slideway 10 intuitively, number of degrees change is less, illustrate that the linearity of line slideway 10 is better, otherwise then linearity is poorer.After straight line degree measurement to the line slideway 10 of frame 9 side, Instrument for Straightness is turned around, first surveyingpin 41 and the second surveyingpin 51 are contacted with two adjacent surfaces of the line slideway 10 of frame 9 opposite side respectively, thus starts to carry out straight line degree measurement to this line slideway.
The foregoing is only preferred implementation of the present utility model; should be understood that; for those of ordinary skills; do not departing under principle prerequisite of the present utility model; multiple remodeling or improvement can be carried out to the utility model; such as match use the first phasing meter and the second phasing meter also can be arranged on the second sway brace; or all install the first phasing meter and second phasing meter of pairing use on the first sway brace and the second sway brace, these are all regarded as within protection domain of the present utility model.
