Abstract
The utility model belongs to measuring instruments and relates to a digital display three-jaw inside micrometer. The digital display three-jaw inside micrometer mainly comprises roller pins, measuring jaws, a base, a digital display differential measuring head assembly, tension springs, idler wheels and a pushing rod. Each roller pin is adhered to one measuring jaw, each measuring jaw is connected with the base in a sliding mode, the base is connected with the digital display differential measuring head assembly in a threaded mode, the base is connected with a bottom cover plate in a threaded mode, each tension spring is connected with a tension spring nail in a sliding mode, the pushing rod is connected with the base in a sliding mode, the pushing rod is connected with the measuring jaws in a sliding mode, a cylindrical pin is adhered to each measuring jaw, each cylindrical pin is connected with one idler wheel in a sliding mode, and each idler wheel is connected with one tension spring in a sliding mode. The digital display three-jaw inside micrometer has the advantages that the structure is compact, the measuring jaws can smoothly move, measuring force is even, and manufacturing cost is low. The digital display three-jaw inside micrometer can be widely applied to precision measurement of inner diameters of mechanical parts.
Description
Technical field
The utility model relates to a kind of surveying instrument, especially a kind of digital display three-jaw micrometer inside caliper.
Background technology
At present, domestic electronic digital display three-jaw micrometer inside caliper is mainly external imported product, manufacturing process complexity not only, and the manufacturing cost height, and also price is higher, is not easy to apply.
Summary of the invention
At above-mentioned situation, the utility model provides a kind of digital display three-jaw micrometer inside caliper.The technical scheme that the utility model adopts is: a kind of digital display three-jaw micrometer inside caliper mainly is made of needle roller, measuring claw, base, digital display differential gauge head assembly, extension spring, roller and push rod.Base and pusher slide are dynamically connected, push rod and measuring claw are slidingly connected, measuring claw and base are slidingly connected, measuring claw and bottom plate are slidingly connected, and measuring claw and needle roller are bonding, and base is connected with the socket cap screw end face with bottom plate, roller and straight pin are slidingly connected, straight pin and measuring claw are bonding, and the extension spring nail is connected with whorl of base, and base is threaded with digital display differential gauge head assembly.
Straight pin and roller are slidingly connected, and roller and extension spring nail are slidingly connected, and roller and extension spring are slidingly connected.
For increasing the smoothness energy that electronic digital display three-jaw micrometer inside caliper measuring claw moves, stuck phenomenon appears when preventing from measuring, in structure, designed roller.
After adopting such scheme, make a kind of digital display three-jaw micrometer inside caliper have compact conformation, measuring claw moves along sliding, and dynamometry is even, and advantage of low manufacturing cost can be widely used in the precision measurement of component of machine internal diameter.
