Abstract

The utility model relates to a vernier micrometer for external diameter, which is mainly composed of a micrometer for external diameter and a vernier. The utility model is characterized in that a bracket (10) of the micrometer body is provided with a main scale (1), and the lower part of the vernier (12) is connected with a movable measuring bar (7) of the micrometer through a vernier bracket (2) and a retaining sleeve (5). A T-shaped slot structure of the vernier (12) is arranged on the main scale (1), and can slide on the main scale (1). The position of the vernier (12) on the main scale (1) is positioned by a fastening screw (11). The utility model has the advantage that one vernier micrometer for external diameter can replace a plurality of micrometers for external diameters; meanwhile, the utility model also has the characteristics of small volume and convenient use.

Description

Vernier micrometer for external diameter

The utility model relates to a kind of mechanical industry measurer.

In the prior art, the measurement range of outside micrometer is less, and the measurement range of each milscale is generally 25mm, as measures 1---the workpiece of 100mm, need four outside micrometer (promptly 0---25mm; 25---50mm; 50---75mm; 75---100mm).Because measurement range is too little, so very inconvenience in real work, processing workman or inspection man must be equipped with simultaneously and manyly could satisfy need of work to milscale.

The purpose of this utility model is to design a kind of cursor type outside micrometer, to increase the measurement range of milscale, reduces the outfit quantity of milscale.

The utility model is achieved in that on the basis of existing milscale, on milscale main body rack (10), load onto a vernier scale (1), go up suit one vernier scale (12) at this main scale (1), vernier scale (12) is connected with the movable measuring staff of milscale (7) with fixed muffle (5) by vernier support (2).According to the size of workpiece size, determine vernier scale (12) earlier during measurement, and then further measure concrete size with milscale in the position of main scale (1).

Advantage of the present utility model is: one can replace the cursor type outside micrometer many outside micrometer; The utility model also has little, the easy to use characteristics of volume simultaneously.

Description of drawings:

Fig. 1 is the structural representation of the utility model embodiment 1;

Fig. 2 is the structural representation of the utility model embodiment 2.

The utility model is further specified as follows below in conjunction with drawings and Examples:

Embodiment 1: as shown in Figure 1, the utility model mainly partly is made up of milscale part and vernier scale, the milscale part mainly comprises: ratchet handle (3), microdrum (4), fixed muffle (5), stop screw (6), movable measuring staff (7), milscale gauge head (8), clamp nut (9) etc., be characterized in vernier main scale (1) is housed on milscale main body rack (10), on vernier main scale (1), be set with vernier scale (12), vernier scale (12) and be connected with the fixed muffle (5) of milscale by support (2).Scales such as 0,20,50,75 are arranged on vernier main scale (1), on vernier scale (12), the location scale is arranged.Vernier scale (12) is sleeved on the main scale on this (1) by its T-slot structure, and vernier main scale (1) middle part has a groove, and a trip bolt (11) is housed on this groove, in order to fixing vernier scale (12).According to the size of workpiece size, determine the position of vernier scale (12) on vernier main scale (1) earlier during work, and locking trip bolt (11), regulate the ratchet handle (3) of milscale then workpiece is measured.

Embodiment 2: as shown in Figure 2, according to embodiment 1 described cursor type outside micrometer, be characterized in housing (15) being housed in the bottom of milscale main body rack (10), at the middle part of housing (15) by cam (14) being housed around axle (13), on the top of housing (15) dial gauge (19) is housed, the opening of housing (15) bottom left end is connected with milscale gauge head (8) by clamp nut (9), and two contacts of cam (14) contact with the afterbody of dial gauge gauge head (16) with milscale gauge head (8) respectively.Like this, the decimal during workpiece calibration can directly be read on dial gauge.According to need of work, can also change above-mentioned dial gauge into clock gauge.

Claims

1, a kind of cursor type outside micrometer, mainly partly form by outside micrometer part and vernier scale, it is characterized in that being equipped with on the milscale main body rack (10) main scale (1), vernier scale (12) bottom is connected with the movable measuring staff of milscale (7) with fixed muffle (5) by vernier support (2), the T-slot structure of vernier scale (12) is contained on the main scale (1), and can go up at main scale (1) and slide, the position of vernier scale (12) on main scale (1) located by trip bolt (11).

2, cursor type outside micrometer according to claim 1, it is characterized in that milscale main body rack (10) bottom is equipped with housing (15), cam (14) is equipped with at housing (15) middle part, dial gauge (19) is equipped with on housing (15) top, housing (15) bottom left end opening is connected with milscale gauge head (8) by clamp nut (9), and two contacts of cam (14) contact with the afterbody of dial gauge gauge head (16) with milscale gauge head (8) respectively.
