Problems solved by technology

For example, in order to ensure the measurement accuracy of traditional calipers, it is necessary to process ultra-high-precision guide rails on the ruler body for the sliding of the ruler frame, and the ruler body is generally a long sheet structure. If you want to process ultra-high-precision guide rails on it, one On the one hand, it requires high-precision mechanical equipment; on the other hand, it requires complex processing procedures and high-tech technicians

Abstract

The present invention relates to a caliper for reducing machining requirements, comprising a caliper body, a fixed measuring jaw, a caliper frame and a movable measuring jaw. The fixed measuring jaw is fixed to one end of the caliper body. The caliper also comprises cylindrical guide rails and fixed seats. Two fixed seats are arranged, and respectively installed on both ends of the caliper body. Two cylindrical guide rails are arranged. Both ends of each of the cylindrical guide rails are respectively installed on the two fixed seats and correspond to positions on one side of the caliper body.Moreover, after the two cylindrical guide rails are installed on the fixed seats, the two cylindrical guide rails are pressed through corresponding first toolings so that respective cylindricity andmutual parallelism reach preset precision, and then are positioned. The caliper frame is slidably sleeved on the two cylindrical guide rails. The cylindrical guide rails in the caliper are standard parts. By pressing the cylindrical guide rails to be a state in which the cylindricity and the parallelism are satisfactory on the caliper body through the corresponding toolings, high-precision machining which is difficult to realize is changed to high-precision assembly which is easy to realize, thereby greatly reducing production cost.

Description

technical field [0001] The invention relates to the field of measuring tools, in particular to a caliper that reduces machining requirements. Background technique [0002] Since the German Marr company produced the world's first vernier caliper in 1871, the mechanical components of ordinary calipers have been used for more than two hundred years, and its basic structure and production process have not changed much so far. [0003] With the advancement of science and technology, people have created new types of calipers such as calipers with tables and digital calipers, but their mechanical components have been used so far without major changes in structure. The mechanical component of the caliper is a component composed of precise mechanical parts. Its processing accuracy is very high, usually requiring a manufacturing accuracy of 0.01mm or more. In order to improve its service life, the components must be heat treated. In order to achieve The dimensional accuracy of the pa...
