Problems solved by technology
However, although this measurement method can be carried out in the part development batch (small batch production), the following shortcomings will be exposed when the parts are mass-produced: 1. The outer side of the part is a cylindrical surface, and it is difficult to keep it vertical when placed in the direction of the notch. There are errors; 2. The number of parts is large, the measurement is inconvenient and the efficiency is low; 3. There are many human factors in the measurement, and the error is large
If the measurement is unqualified and repaired, the secondary positioning measurement will cause errors

The invention discloses a measuring clamp for distance from space circle center to end face. The measuring clamp comprises a base, a blocking piece, a first pin, a positioning pin, a second pin, a blocking piece screw, a positioning pin screw and a nut, wherein a V-shaped groove is formed in the center of the upper surface of the base and penetrates through the upper surface of the base in the front-back direction of the base, and the base is used for containing a measured part; and the blocking piece is fixed to the front side wall of the base through the blocking piece screw and attached toone end face of the V-shaped groove penetrating through the upper surface of the base. According to the measuring clamp for the distance from the space circle center to the end face, the part detection efficiency is improved, the product quality is guaranteed, and certain economic benefits are obtained. Meanwhile, the technical level and the capacity for solving practical problems are improved.
Description
technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a fixture for measuring the distance from a space center to an end face. Background technique [0002] Locating pin is a structure that often appears on aircraft. The material of this type of part is 30CrMnSiNi2A, high-strength structural steel. The material has high toughness, is not easy to cut, and is difficult to process. It is widely used in the aerospace field. Some dimensions in the positioning pin are extremely important. The dimension that the positioning pin needs to ensure is that the dimension from the center of the space to the end face is 24±0.05mm, and due to the limitation of use requirements, the center of the circle is not on the theoretical outer circle of the part body, so in practice In processing and measurement, this dimension is a spatial dimension and cannot be measured directly. The previous measurement method is to place the p...
