Detailed Description
The invention will be further described with reference to the following examples:
as shown in fig. 1-4, the detecting pin for detecting the depth of the profile of the component of the present invention comprises a detecting pin 1, a fixing sleeve 2, a locking pin 3, a detecting sleeve 4 and a handle 5.
The detection pin 1 is composed of a guide shaft 11, a thread part 12 and a fixing part 13, wherein the guide shaft 11 is a polished rod, the thread part 12 is a threaded rod connected with the polished rod, the diameter of the polished rod is the same as that of the threaded rod, and the polished rod and the threaded rod are integrally formed; the fixing portion 13 is screwed with the screw portion 12, and the fixing portion 13 can be detached separately. The detection sleeve 4 is sleeved on the guide shaft 11 and is in clearance fit with the guide shaft 11. The handle 5 is fixed with the external thread of the thread part 12 through the internal thread, and the front end of the handle 5 is in transition fit with the detection sleeve 4 without riveting or welding. And a sliding gap of 0.1mm is reserved at the contact part of the detection sleeve 4 and the handle 5. And one side of the handle 5 is provided with a fixing part connected with the threaded part and used for preventing the handle 5 from being separated from the threaded rod. And anti-skid knurls are arranged on the outer side of the handle 5.
The locking pin 3 is arranged on the outer side of the fixed sleeve 2, a threaded hole with the diameter of 6.0 is formed in the same position with the fixed sleeve 2 and the detection sleeve 4, the locking pin 3 is directly screwed in by threads, the locking pin 3 is provided with a locking handle, and the detection pin 1 can be directly locked or loosened by swinging the locking handle left and right, so that the detection pin 1 can move back and forth or be locked.
The working process is as follows:
the detection pin 1 is guided to penetrate into the molded surface position of the detected part through a detection hole (the size of the detection hole of the detection tool is set to be +1 mm) in the corresponding position on the detection tool, when the length of the detection pin 1 is insufficient, the handle 5 is manually screwed in to enable the detection pin 1 to move back and forth, and therefore the purpose that the detection pin is contacted with the molded surface of the detected part is achieved.
When the detection pin 1 is completely contacted with the molded surface of the part to be detected, the locking pin 3 is locked leftwards (whether the locking pin is locked rightwards or locked leftwards according to the specific requirements during manufacturing) under the action of manual external force, and after the action is finished, an inspector holds the inside of a hand and measures the width of a part A (shown in figure 1) by using a caliper. When the gap at the position A is large, the fact that the molded surface of the detected part deviates in the outward direction is described, and when the gap at the position A is small, the fact that the molded surface of the detected part deviates in the inward direction is described, so that whether the specific data of the molded surface of the detected part meets the requirements of a drawing or not can be judged, and the detection work is finished.
The utility model discloses degree of depth detects the round pin, detects some precision and should guarantee at positive and negative 0.01mm, other some positive and negative 0.3 mm. The surface hardness is 52-60HRC, and the surface of the handle 5 is knurled.
