Problems solved by technology

When processing the cage parts, the inner spherical surface is ground. This method cannot realize the detection of the parts on the grinding machine with the clamp positioning of the grinding machine. The parts need to be disassembled repeatedly, the repeated positioning error increases, the detection time is long, and the efficiency is low. Can not meet the on-site mass production

Abstract

The invention discloses a diameter measuring tool of an inner spherical section circle and a measuring method. The measuring tool comprises a base, a first movable measurement unit, a first data reading device and a fixed measurement unit, wherein the fixed measurement unit comprises two contoured fixed bulbs; the two fixed bulbs are fixedly arranged on the base; a movement center of the first movable measurement unit and the two fixed bulbs form an isosceles triangle on the same plane; one end of a first movable measurement unit is connected with a second movable measurement unit through a spring; the other end of the first movable measurement unit contacts a reading meter measuring head of the first data reading device; the second data reading device stops at one end of the second movable measurement unit; and the first movable measurement unit and the second movable measurement unit are arranged on the base and can carry out axial slot clearance sliding along the axis on which a connecting line of the second movable measurement unit and the first movable measurement unit is. The diameter measuring tool can meet detection of the diameter of the inner spherical section circle with fixed distance; and the measuring method is reliable and suitable for field and volume production.

Description

technical field [0001] The invention relates to a measuring tool and a measuring method based on the measuring tool, in particular to a measuring tool and a measuring method for the diameter of an inner spherical section circle. Background technique [0002] Cages for important parts of high-pressure plunger pumps, such as Figure 1a as well as Figure 1b , the D0 dimension Ф64.226±0.05 in the enlarged picture is the key dimension, which requires 100% detection, see figure 2 . D0 is the diameter of the section circle at the distance Z0=2±0.01 from surface A. When measuring it, the method of point measurement with a three-coordinate measuring machine is used. This measurement method requires high skills of technicians, and processing workers often do not have this skill. When processing the cage parts, the inner spherical surface is ground. This method cannot realize the detection of the parts on the grinding machine with the clamp positioning of the grinding machine. The...
