Embodiment

[0022] Such as Figure 1~5 As shown, a detection tool for measuring the small diameter of the conical platform at the inner end of a deep hole includes a main rod 1 and a measuring rod 2 parallel to the main rod 1. The main rod 1 is sequentially provided with a positioning cone 3 and a fixing clip from bottom to top. 4 and guide rail 5, the positioning cone 3 is slidably arranged on the main rod 1, and the positioning cone 3 is coaxial with the main rod 1, and a measurement is provided from the peripheral surface of the positioning cone 3 to the axis. Groove 3-1, the end surface of the measuring groove 3-1 is provided with a scale line;

[0023] The measuring rod 2 is provided with a handle 6 and a drag block 7, the handle 6 is slidably arranged on the measuring rod 2, and the handle 6 cooperates with the guide rail 5 to drive the measuring rod 2 close to or away from the measuring rod 2. The main rod 1 moves, the drag block 7 is overlapped with a cursor 8, and the cursor 8 t...

Abstract

The invention, which belongs to the technical field of the measuring instrument, in particular relates to a detection tool for measuring the small diameter of a tapered table at the inner end of a deep hole. The detection tool comprises a main rod and a measuring rod parallel to the main rod. A positioning cone, a fixed clamp and a guide rail are arranged successively at the main rod from bottom to top; the positioning cone is arranged at the main rod in a sliding manner; and the positioning cone and the main rod are arranged coaxially. A measuring slot is formed from the peripheral surface ofthe positioning cone to the axis of the positioning cone; and a scale line is arranged on the end surface of the measuring slot. A handle and a dragging block are arranged on the measuring rod; the handle is arranged on the measuring rod in a sliding manner; and the handle and the guide rail cooperate with each other to drive the measuring rod to approach or move away from the main rod. A vernieris arranged at the dragging block in an overlap joint manner and makes translation along the measuring slot with the dragging block; the vernier is arranged between the fixed clamp and the positioning cone; the axial motion of the vernier is limited by the fixed clamp and the dragging block; and the vernier is separated from the dragging block when the measuring rod is in a zero-gravity state.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, in particular to a detection tool for measuring the small diameter of a conical pedestal at the inner end of a deep hole. Background technique [0002] Due to the difference in depth and diameter, traditional measurement tools often have measurement difficulties and large errors in measurement data when measuring the conical platform inside a deep hole. Measurement, the cost is high, the operation technology content is high, and on-site measurement cannot be done. For the measurement of non-standard parts, the measurement personnel often need to go to the site to measure the assembly situation. This product mainly solves how to quickly and accurately measure the cone inside the deep hole. At the same time, this product can also determine the depth of deep holes and improve the internal dimensions of deep hole parts. It is easy to operate and easy to master, suitable for on-site meas...
