Embodiment Construction

[0032] Below in conjunction with accompanying drawing, technical scheme of the present invention will be further described:

[0033] Such as figure 1 , figure 2 As shown, the high-protection direct-acting digital display micrometer of the present invention (meeting the batch rapid measurement requirements) is assembled from a measuring head 1, a propulsion assembly 2, a display screen 3 and a U-shaped ruler bow 4, wherein the display screen 3 and the U-shaped ruler bow 4 are assembled. The type ruler bow 4 is fixedly connected with screws, the measuring head 1 is built in the display screen 3 and the front end of the measuring head 1 is sleeved with the U-shaped ruler bow 4, and the propulsion assembly 2 is connected to the measuring head 1 rear end.

[0034] The measuring head 1 is a precision shaft system, mainly composed of a measuring sleeve 5, a measuring rod 6, a positioning sleeve 9, a guide column 10, a screw 14, a main grid seat 11, an overhanging shrapnel 12, a lim...

Abstract

The invention discloses a high-protection direct-acting digital display micrometer, which comprises a measuring head, a propelling assembly, a display screen and a U-shaped arch, a tube body of a measuring bush is embedded into the display screen, the front section of the measuring bush is embedded into the U-shaped arch, a measuring rod is arranged inside the measuring bush, the front section of the measuring rod is in sliding fit with a positioning sleeve on the front end of the measuring bush, and the rear section of the measuring rod is supported on an adjusting screw which is vertically arranged on the rear section of the measuring bush in a sliding way through two linked guide pillars on two sides of the measuring rod; a main grid is arranged on a main grid seat, and an auxiliary grid is in floating fit with the main grid through a suspension stretching spring leaf which is installed on the tube body of the measuring bush; an electric appliance null-setting mechanism is arranged between the measuring rod and the positioning sleeve; and a large-pitch lead screw of the propelling assembly is in floating connection with the measuring rod through a steel ball. The measuring rod structure and the electric appliance null-setting mechanism in precise positioning on the front end and auxiliary positioning on the rear end are adopted to be matched with a floating auxiliary grid component, so that the movement and measurement precision of a sensor can be guaranteed; and moreover, the structure is simple, easiness in assembling is realized, and the cost is low.

Description

(1) Technical field: [0001] The invention relates to a measuring instrument, in particular to a high-protection direct-acting digital display micrometer. (2) Background technology: [0002] The existing direct-acting digital display micrometers all use a mechanical zero calibration mechanism. Micrometers with a size of 0 to 25 mm are directly zeroed with an anvil and a measuring rod, and micrometers with specifications above 25 mm are zeroed with a standard measuring rod. Due to the change of mechanical components, the zero point may change. In order to ensure the measurement accuracy of the micrometer, it must be zeroed before use, and it must be zeroed in the middle of long-term use. . (3) Contents of the invention: [0003] Aiming at the shortcomings of the traditional direct-acting digital display micrometer, the present invention designs a high-protection direct-acting digital display micrometer with absolute electrical zero point correction. [0004] A high-protect...
