Internal flatness detection device suitable for hydraulic pipe fitting production

Abstract

The invention discloses an internal flatness detection device suitable for hydraulic pipe fitting production. According to the device, a movable sleeve is installed at the inner end of a base body sleeve in a nested mode to form a telescopic structure, a threaded butt joint piece is installed on the inner side of the movable sleeve in a penetrating mode, and a traction rope is in butt joint with the upper end of the movable sleeve; wherein the tail end of the traction rope is in butt joint with the outer end of the base body sleeve, a guide groove is formed in the outer side of the base body sleeve, and the base body sleeve is in butt joint with a connecting piece through the guide groove. According to the internal flatness detection device suitable for hydraulic pipe fitting production, a user only needs to hold a movable sleeve to move along the interior of a self-positioning base body sleeve, and then a contact piece can be driven to synchronously move outwards along the inner wall of a pipe fitting from bottom to top in an attached mode; when a user touches an uneven position, the stressed contact piece is matched with repulsive thrust between the magnet pieces to enable the buffer piece to be in contact with the contact switch, so that the buffer piece is matched with the buzzer to carry out accurate alarm work at the corresponding position, and thereby the user can rapidly repair a mark at the corresponding position.

Description

technical field [0001] The invention relates to the technical field of hydraulic pipe fittings, in particular to an internal flatness detection device suitable for the production of hydraulic pipe fittings. Background technique [0002] Hydraulic pipe fittings are one of the more common components in hydraulic equipment. The production steps are relatively cumbersome. At the same time, it is necessary to sample and test the flatness of the inner wall of the finished product. Defects, such as: [0003] For example, a pipe fitting roundness detection tooling and detection assembly whose publication number is CN208398784U does not need to frequently move the pipe fittings, reduces labor cost input, improves roundness detection efficiency and shortens working hours, but the existing one is suitable for the production of hydraulic pipe fittings. Most of the detection devices can only detect a single type of workpiece, which cannot quickly and stably realize the high-precision de...

Problems solved by technology

[0006] The purpose of the present invention is to provide an internal flatness detection device suitable for the production of hydraulic pipe fittings, to solve the problem that most of the above-mentioned background technologies can only be detected for a single type of workpiece, and it cannot quickly and stably detect the inner ends of different types of workpieces. To achieve the detection requirement of maintaining high precision, the practical limitations are relatively large. During the detection process, activities need to be carried out, and the movement process is accompanied by jitter, which leads to the inability to guarantee the detection stability and accuracy, and further affects the operation of the user. inconvenient problem
