Abstract
The utility model relates to a back bolt hole detection tool which is characterized by comprising a sleeve core with a cylindrical body and a sleeve which has two open ends and can be sleeved over the body. The sleeve core further comprises a projection portion arranged at one axial end of the body and protruding from the circumferential side, and the profile of the projection portion matches with the inner shape of any circumferential position of the reamed hole. The maximal radial size of the sleeve core equals to the diameter of a straight hole. The detection tool detects the size of a reamed hole by rotating of the projection portion of sleeve core, which is rapid, simple and effective. A sleeve independent of the sleeve core satisfies the requirement of extending the sleeve core in the back bolt hole, and ensures the stability of the sleeve core during detection by preventing radial shaking of the sleeve core through the sleeve. Mounting and dismounting are convenient. After processing of a back bolt hole is completed, the detection tool detects whether the reamed hole is qualified. The detection tool is simple in structure, low in operation requirement, convenient for carrying around and maintenance, and low in cost.

The utility model has solved the defect existed in the background technology, has following beneficial effect:
1. testing tool of the present utility model, utilize the detection of the ingenious realization of the cover rotation of core protuberance in reaming to the reaming size, fast, simply, effectively; Setting is independent of the sleeve of cover core, has both met the requirement that the cover core can stretch into back of the body keyhole, can prevent from overlapping radially rocking of core by sleeve again, the stability of cover core while guaranteeing to detect, and be convenient to installation and removal.The utility model testing tool, after back of the body keyhole machines, plays the whether qualified effect of check reaming quality, simple in structure, not high to operation requirements, is convenient for carrying and keeps in repair, with low cost.
The second body back to a circumferential side of protuberance with respect to the first noumenon indentation, reduce on the one hand the radial dimension that whole cover core is provided with protuberance one end, can stretch into smoothly back of the body keyhole straight hole, make on the other hand the radial dimension of the first noumenon be greater than the second body, be conducive to guarantee the intensity of cover core integral body.In other words, if the radial dimension of the first noumenon equals the second body, for making to overlap core, be provided with protuberance one end and can stretch into smoothly straight hole, it is less that the size of whole body must arrange, thereby affect intensity.
3. protuberance the inner vertically arranges plane perpendicular to axial direction, and stop sleeve that can be more stable makes sleeve and cover core keep coaxial, improves accuracy in detection.The axial both sides of protuberance profile matches with the interior shape of straight hole, is convenient to overlap core and puts into smoothly back of the body keyhole and take out from back of the body keyhole, in process, keeps contacting with the straight hole hole wall is mellow and full, avoids damage.
4. the outside surface of sleeve can arrange the mark part such as hole, groove, scale mark, as module, makes sleeve have the function that detects the straight hole hole depth.Further sleeve is set to two sections different ，Bing centers of external diameter the triangle groove part that serves as a mark is set, and makes sleeve also can detect the aperture quality of straight hole simultaneously, increases the measuring ability of this testing tool, makes can more fully detect back of the body keyhole.
5. control the axial length of cover core and sleeve, make while being arranged in back of the body keyhole, the straight hole upper end can be exposed respectively in the upper end of sleeve and cover core, is convenient on the one hand pinch the cover core and rotates the detection of carrying out reaming, is convenient on the other hand detect the complete extending part that directly pinches and takes out sleeve and cover core.Further the outer wall in cover core extending part arranges decorative pattern, can increase mantle friction, is convenient to, with hand, it is rotated to operation, is difficult for skidding.
6. with the cover core, while coordinating, the sleeve top, preferably higher than cover core the second body, makes upper cartridge to contact with the first noumenon is stable to sleeve, thus avoid gap between the second body and sleeve to cause overlapping core at sleeve diameter to the situation of rocking.
