Abstract

The utility model discloses a linearity measurer which comprises a long guideway of both ends are respectively provided with a support seat. A slide block is arranged on the long guideway, and is connected with a meter rack on which a measuring meter is clamped. The support seat is also arranged on the slide block. The precision of the measurer is high, the linearity measurer is commonly used in the daily production, and the measuring process is quite simple. The linearity measurer can also be used for the relay measurement of long workpieces.

Description

Instrument for Straightness

The utility model relates to a kind of mechanical measurement utensil.

In the existing mechanical processing and manufacturing technology, the utensil of measuring workpieces linearity is more rare, generally all measure, for example work rest is located on the lathe, utilize the planker on the lathe by means of lathe, on planker, set up scale, observe the pointer displacement amount of scale during moving carriage, this method is cumbersome, and is also accurate not to the utmost, because itself also has straightness error the lathe guide rail, and in use the precision of lathe is degenerated day by day; The optical instrument of special-purpose measurement linearity etc. is also arranged in addition certainly, but in daily production, be difficult to use.

The purpose of this utility model is: a kind of Instrument for Straightness is provided, and the precision of this measuring instrument is higher, and can often use in daily production, and the method for measurement is also quite simple.

The technical solution of the utility model is: a kind of Instrument for Straightness, this measuring instrument comprise that two ends are provided with the long guideway of bearing, and described long guideway is provided with slide block, is connected with dial framework on the slide block, and clamping has scale on the dial framework.

The further technical scheme of the utility model is: a kind of Instrument for Straightness, this measuring instrument comprise that two ends are provided with the long guideway of bearing, and described long guideway is provided with slide block, is connected with dial framework on the slide block, and clamping has scale on the dial framework; Also be provided with bearing on the described slide block; Described bearing is connected to form by the supporting seat of studdle and studdle bottom, and studdle cooperates with set nut on the long guideway, and the top of studdle also is fixed with wing nut; The bottom of described supporting seat is provided with magnet; Described slide block is made up of two L-shaped loam cake and lower covers in cross section up and down, and loam cake and lower cover are connected and fixed by contiguous block of their centres, and embrace long guideway, are provided with the holding device that holds out against long guideway above the side of loam cake and lower cover and the loam cake; Be provided with set screw between described lower cover and the contiguous block; Described holding device is the steel ball that is provided with in the hole, spring, screw silently.

The utility model has the advantages that:

1. the utility model need not come workpiece is carried out straight line degree measurement by lathe, and is simple and easy to use, can often use in daily production.

2. because this measuring instrument is provided with bearing on slide block, so it can be measured long workpiece, pack up the bearing on the long guideway as long as put down the bearing on the slide block during measurement, the moving long guide rail carries out relay and measures.

3. the long guideway in this measuring instrument adds precision and the verticality of only requiring two faces man-hour, is benchmark with these two faces during measurement, thereby has reduced manufacture difficulty and cost.

4. owing to be provided with set screw between the lower cover of slide block and the contiguous block, two verticality between the reference field can be regulated,, its precision can be adjusted so use for a long time after this measuring instrument.

The utility model will be further described below in conjunction with drawings and Examples:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model;

Fig. 3 is a cut-open view of the present utility model.

Wherein: 1. bearing; 2. long guideway; 3. slide block; 4. dial framework; 5. scale; 6. studdle; 7. supporting seat; 8. set nut; 9. wing nut; 10. magnet; 11. loam cake; 12. lower cover; 13. contiguous block; 14. holding device; 15. set screw; 16. hole; 17. steel ball; 18. spring; 19. screw silently.

Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of Instrument for Straightness, this measuring instrument comprises that two ends are provided with the long guideway of bearing [1] [2], and described long guideway [2] is provided with slide block [3], is connected with dial framework [4] on the slide block [3], and dial framework [4] is gone up clamping scale [5]; Described slide block [3] is provided with two bearings [1]; Described bearing [1] is connected to form by the supporting seat [7] of studdle [6] and studdle [6] bottom, and studdle [6] cooperates with set nut [8] on the long guideway [2], and the top of studdle [6] also is fixed with wing nut [9]; The bottom of described supporting seat [7] is provided with magnet [10]; Described slide block [3] is made up of two L-shaped loam cake [11] and lower covers [12] in cross section up and down, loam cake [11] and lower cover [12] are connected and fixed by the contiguous block [13] in the middle of them, and embrace long guideway [2], be provided with the holding device [14] that holds out against long guideway [2] above the side of loam cake [11] and lower cover [12] and the loam cake [11]; Be provided with set screw [15] between described lower cover [12] and the contiguous block [13]; Described holding device [14] is the steel ball [17] that is provided with in the hole [16], spring [18], screw [19] silently.The utility model need not come workpiece is carried out straight line degree measurement by lathe, and is simple and easy to use, can often use in daily production; Because this measuring instrument is provided with bearing [1] on slide block [3], so it can be measured long workpiece, pack up the bearing [1] on the long guideway [2] as long as put down the bearing [1] on the slide block [3] during measurement, moving long guide rail [2] carries out relay and measures; Long guideway in this measuring instrument [2] adds precision and the verticality of only requiring two faces man-hour, is benchmark with these two faces during measurement, thereby has reduced manufacture difficulty and cost; Owing to be provided with set screw [15] between the lower cover [12] of slide block [3] and the contiguous block [13], can regulate two verticality between the reference field, so use for a long time after this measuring instrument, can adjust its precision.
