Description
Technical Field
The utility model relates to an interior hexagonal detects technical field, especially indicates a special utensil of examining of interior hexagonal axiality.
Background
The hexagonal that often sees in the life is hexagonal spanner or mechanical device, interior hexagonal adopts the drift to dash the square and forms, have simple and light, easy manufacturing, advantages such as low cost and simple to use, and a certain amount of deviation can appear in the product dashes the square in-process, lead to machining precision not enough, make the hole size of interior hexagonal appear the deviation, it is too big also to probably lead to being detected interior hexagonal axiality difference, and lack the instrument that can detect product hexagonal hole precision and axiality simultaneously, cause unqualified product to flow into market, cause certain influence and potential safety hazard to the user, an urgent need not only can be used for detecting interior hexagonal precision but also can detect whether the detection apparatus of interior hexagonal axiality is in qualified scope.
SUMMERY OF THE UTILITY MODEL
The utility model provides an utensil is examined in special use of interior hexagonal axiality inspection has solved the problem that interior hexagonal hole size and axiality are not good to be detected.
The technical scheme of the utility model is realized like this:
a special checking fixture for checking internal hexagonal coaxiality comprises a base and a checking rod, wherein an opening is formed in the middle of the lower end face of the base and used for detecting the coaxiality of a workpiece, a hexagonal hole is formed in the working end of the workpiece, and an inner hole communicated with the opening is formed in the middle of the upper end face of the base; the upper end of the inspection rod is a handle, the lower end of the inspection rod is a hexagonal rod, and the hexagonal rod is arranged in an inner hole of the base and used for detecting a hexagonal hole of a workpiece.
Furthermore, the shaft diameter of the handle is larger than the inner hole, and the shaft diameter of the hexagonal rod is smaller than the inner hole.
Furthermore, a sponge washer is arranged at the joint of the upper end surface of the base and the handle.
The beneficial effect that this technical scheme can produce:
whether the coaxiality of a workpiece reaches the standard is judged by judging whether the workpiece can be inserted into the opening of the base or not, and then whether the inner hexagon of the workpiece is qualified or not is tested by the inspection rod, so that the inspection tool solves the problem that the coaxiality and the inner hexagon precision of the workpiece are not good in inspection, meanwhile, the inspection is more convenient and faster, and the working efficiency is improved; the shaft diameter of the handle is larger than the inner hole, and the shaft diameter of the hexagonal rod is smaller than the inner hole, so that the handle is clamped on the base to prevent the inspection rod from falling downwards to cause damage to a workpiece; set up the sponge packing ring and can prevent that inspection rod and base from colliding each other in the complex, prevented to cause the injury influence each other and influence the detection, prolonged equipment life.

Detailed Description
In order to clearly explain the technical features of the present solution, the present solution is described below by way of specific embodiments.
Example 1
A special checking fixture for checking internal hexagonal coaxiality comprises a base 1 and a checking rod 2, wherein an opening 11 is formed in the middle of the lower end face of the base 1 and used for detecting the coaxiality of a workpiece 3, a hexagonal hole 31 is formed in the working end of the workpiece 3, and an inner hole 12 communicated with the opening 11 is formed in the middle of the upper end face of the base 1; the upper end of the inspection rod 2 is a handle 21, the lower end of the inspection rod is a hexagonal rod 22, and the hexagonal rod 22 is arranged in the inner hole 12 of the base 1 and used for detecting a hexagonal hole 31 of the workpiece 3.
The utility model discloses the use as follows: firstly, taking out a workpiece 3, wherein the workpiece 3 is cylindrical, the working end of the workpiece 3 is processed into a hollow hexagonal hole 31 through punching, the working end of the workpiece 3 is inserted into the opening 11 of the base 1, the hexagonal rod 22 of the inspection rod 2 is inserted from the inner hole 12 at the upper end of the base 1, the hexagonal rod 22 is connected with the workpiece 3, then the hexagonal rod 22 is continuously inserted downwards, the hexagonal rod 22 penetrates through the inner hole 12 to be inserted into the hexagonal hole 31 of the workpiece 3, the inspection rod 2 is matched with the hexagonal hole 31, the inner hexagon of the workpiece 3 is processed to be qualified if the matching is successful, the unqualified workpiece 3 is not matched, the workpiece 3 and the inspection rod 2 are taken down after the detection is finished, and a new workpiece 3 is taken to be inserted for detection.
Whether the axiality of work piece 3 is up to standard is judged through opening 11 that whether the processing end of work piece 3 can insert base 1, then whether processing is qualified in hexagonal hole 31 through hexagonal stick 22 test work piece 3, and this is examined the problem of having solved the not good detection of work piece 3 axiality and hexagonal hole 31 precision, also makes the convenient and fast more that detects simultaneously, has improved work efficiency.
