Description

Plum blossom form inside groove size gauge
Technical Field
The utility model belongs to the technical field of the size detection, concretely relates to plum blossom form inside groove size gauge.
Background
The detection of the size of the groove type inside the part of the novel nuclear fuel element is mainly carried out by optical equipment at home and abroad at present.
As shown in figure 1, the plum blossom-shaped inner groove of the nuclear fuel element part comprises three semicircular grooves uniformly distributed at 120 degrees, and the plum blossom-shaped inner groove of the part needs to detect the radius of the semicircular grooves, the angle between the semicircular grooves, the arc width of the semicircular grooves, the symmetry degree of the semicircular grooves, the distance from the circle center to the topmost end of the semicircular grooves and the like in the detection process. The structure needs more detection items, and at present, the structure detection mainly adopts optical equipment such as a projector, an image measuring instrument and the like for detection. Because it is axle type part, the same position can not be arranged in fast in the inside groove process of placing at every turn, and spare part size precision is higher, leads to detecting speed slower among the big batch testing process, influences the detection progress.
Disclosure of Invention
An object of the utility model is to provide a plum blossom form inside groove size gauge realizes the plum blossom form inside groove size short-term test of spare part.
The technical scheme of the utility model as follows:
a plum blossom-shaped inner groove size gauge is used for measuring plum blossom-shaped inner groove type nuclear fuel element parts, and inner grooves of the plum blossom-shaped inner groove type nuclear fuel element parts comprise three semi-circular grooves which are arranged at intervals of 120 degrees;
the gauge comprises a go gauge and a no-go gauge;
the go gauge and the no-go gauge have the same structure and different sizes;
the go gauge comprises a measuring head, an inner hexagonal socket head cap screw and a handle;
three measuring semicircles and three limiting cones are arranged on the measuring head at intervals along the circumferential direction, wherein the interval between the central line of one measuring semicircle and the central line of one limiting cone is 60 degrees;
a step hole is processed in the center of the measuring head, the central axis of the step hole is overlapped with the central axis of the measuring head, and the step hole penetrates through two opposite side surfaces of the measuring head;
the nut end of the inner hexagonal socket head cap screw is clamped on the step hole of the measuring head, and the screw rod end penetrates through the step hole to be fixedly connected with one end of the handle in a threaded manner;
the handle is coaxial with the measuring head.
The go gauge can pass through the inner groove of the plum blossom-shaped inner groove type nuclear fuel element part, and the no-go gauge cannot pass through the inner groove of the plum blossom-shaped inner groove type nuclear fuel element part.
The beneficial effects of the utility model reside in that:
(1) the utility model discloses the gauge not only can guarantee the accuracy that detects the precision in the use, makes detection efficiency promote by a wide margin moreover.
(2) The utility model discloses can conveniently accomplish single or big nuclear fuel component spare part plum blossom form inside groove's all size detection in batches fast, guarantee the production progress.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The plum blossom-shaped inner groove size gauge shown in fig. 2 to 3 comprises a go gauge and a no-go gauge, and is used for measuring plum blossom-shaped inner groove type nuclear fuel element parts 4.
As shown in fig. 1, the inner groove of the quincunx-shaped inner groove-type nuclear fuel element part 4 comprises three semicircular grooves arranged at intervals of 120 °.
The go gauge and the no-go gauge have the same structure and different sizes.
The go gauge comprises a measuring head 1, an inner hexagonal socket head cap screw 2 and a handle 3.
Three measuring semicircles and three limiting cones are arranged on the measuring head 1 at intervals along the circumferential direction, wherein the interval between the central line of one adjacent measuring semicircle and the central line of one limiting cone is 60 degrees. The center position of measuring head 1 process the step hole, the axis in step hole and the coincidence of the axis of measuring head 1, the step hole runs through two relative sides of measuring head 1. The specific size can be obtained by calculating the size of the measuring semicircle according to the design manual of the smooth limit gauge.
The nut end of the socket cap screw 2 is clamped on the step hole of the measuring head 1, and the screw rod end penetrates through the step hole to be fixedly connected with one end of the handle 3 through threads. The handle 3 is coaxial with the measuring head 1.
As shown in fig. 4 to 5, during the detection, it is only necessary to ensure that the go gauge can pass through the inner groove of the quincunx-shaped inner groove-shaped nuclear fuel element part 4, and the no-go gauge cannot pass through the inner groove of the quincunx-shaped inner groove-shaped nuclear fuel element part 4, that is, the size of the quincunx-shaped inner groove-shaped nuclear fuel element part 4 is qualified.
