Deep hole inner wall strain gauge adhering tool for steel rolling sensor

Abstract

The invention discloses a deep hole inner wall strain gauge adhering tool for a steel rolling sensor. The deep hole inner wall strain gauge adhering tool for the steel rolling sensor comprises a pipe body and a locating base. The locating base is provided with a ball valve, and a gas connector is arranged at the outer end of the locating base. A plurality of exhaust holes are formed in the side wall of the pipe body, the outer side of the pipe body is sleeved with a silicon rubber sleeve, and the two ends of the silicon rubber sleeve are connected with the outer sides of the two ends of the pipe body in a sealing mode. A silicon rubber inner sleeve is arranged between the inner side of the silicon rubber sleeve and the outer side of the pipe body. A plurality of annular grooves are formed in the outer side surface of the pipe body at intervals in the axial direction, and a plurality of hoop rings are arranged on the outer side surface of the silicon rubber inner sleeve. Accordingly, the deep hole inner wall strain gauge adhering tool for the steel rolling sensor has the advantages that a strain gauge can adhere to the deep hole inner wall accurately, the adhering position is accurate, the strain gauge can be separated from the tool conveniently after adhesion, the pressure on the strain gauge acts on the strain gauge stably and continuously in the adhering process and can be adjusted conveniently, and the strain gauge can adhere to the deep hole inner wall firmly.

Description

technical field [0001] The invention relates to the technical field of sensor processing, in particular to a deep hole inner wall strain gauge pasting tooling for a steel rolling sensor. Background technique [0002] At present, for the rolling steel sensor used in the metallurgical industry, the strain gauge is pasted on the inner wall of the deep hole. Due to the small diameter of the deep hole, it cannot be directly pasted manually, and the strain gauge needs to be pasted with the help of tooling. Some of the common patch tooling nowadays cannot achieve high-quality patching on the inner wall of the deep hole. Usually, the position of the strain gauge sticking is relatively large, or the strain gauge is not firmly pasted, and it is easy to fall off, which seriously affects the performance of the sensor. [0003] For example: Chinese Patent Authorization Announcement No.: CN2326948Y, the authorized announcement date was June 30, 1999, which discloses an in-pipe patch tool,...
