Abstract
The utility model relates to a novel direct-acting digital display micrometer, which comprises a measuring rod, a rotary sleeve and a digital display unit, wherein the measuring rod is mounted on a U-shaped measuring frame, the rotary sleeve is mounted at the end of the measuring rod, and the digital display unit is arranged between the U-shaped measuring frame and the rotary sleeve. Besides, an auxiliary grid and a main grid of a capacitance transducer are arranged in a casing of the digital display unit, the main grid is parallel to the measuring rod and fixedly mounted in the casing, and the auxiliary grid is mounted on the measuring rod via an elastic mechanism. The elastic mechanism comprises a shaft sleeve, a connecting plate and an elastic press piece, the shaft sleeve is sleeved on the measuring rod closely, the connecting plate is connected with the shaft sleeve, the elastic press piece is fixedly connected with the connecting plate and is also connected with the auxiliary grid, and a seal ring is arranged between the measuring rod and the casing. A movable grid of the digital display micrometer is arranged on the measuring rod indirectly, is connected with the measuring rod by the aid of the elastic mechanism and moves along with the measuring rod, so that polished-rod characteristics of the measuring rod are guaranteed. Further, a gap reserved between the measuring rod and the casing of the digital display unit can be eliminated by the aid of the seal ring, and accordingly full seal of the digital display unit is realized truly.
Description
(1) technical field:
The utility model relates to digital display appliance, is specially a kind of novel Direct Action Type digimatic micrometer.
(2) background technology:
Milscale develops to digimatic micrometer from the mechanical type milscale, the traditional structure of digimatic micrometer is to drive sounding rod by turning set to move, the secondary grid by the capacitive transducer that is provided with on the sounding rod whole piece body of rod and the measurement of inductance sounding rod amount of movement of main grid are realized the measurement to workpiece, because main grid is contained on the sounding rod, main grid on the sounding rod body of rod has influenced the sealing between the sounding rod body of rod and the digital display device housing, thereby the housing of this digimatic micrometer can't be accomplished hermetic high-protection level, particularly under wet environment, use, because the entering of steam, digital display device is caused harmful effect and then influences the measurement result of digimatic micrometer.
(3) utility model content:
The purpose of this utility model provides a kind of novel Direct Action Type digimatic micrometer, reaches dustproof, waterproof purpose by hermetically sealed design.
Can realize the novel Direct Action Type digimatic micrometer of above-mentioned purpose, comprise that being installed on U-shaped surveys the sounding rod on the frame and the turning set of sounding rod termination, U-shaped is surveyed the digital display device that sounding rod is set between frame and the turning set, described sounding rod passes the housing of digital display device, be provided with the main grid and the secondary grid of the capacitive transducer of measurement of inductance bar amount of movement in the described housing, different is, described main grid horizontal survey bar is installed in housing, and described secondary grid are installed on the sounding rod by follower, O-ring seal is set between the housing of described sounding rod (polished rod) and digital display device can be easy to realize the hermetically sealed of digital display device.
Described follower is the elastic mechanism that main grid and secondary grid are reliably contacted.
A kind of structure of described elastic mechanism comprises axle sleeve, brace and elastic pressuring plate, and axle sleeve is locked on the sounding rod, be connected brace and be connected of brace connecting bushing, elastic pressuring plate with secondary grid, and under the effect of elastic pressuring plate, secondary grid contact with main grid.
Advantage of the present utility model:
The moving grid of the utility model Direct Action Type digimatic micrometer is not to be set directly on the sounding rod, follow it and move but be connected with sounding rod by elastic mechanism, guaranteed the polished rod characteristic of sounding rod, gap between the housing of itself and digital display device can solve by O-ring seal is set, and realizes truly hermetically sealed of digital display device.
