Abstract
The utility model relates to the technical field of machinery manufacturing, in particular to a thread processing clamp on an aviation instrument sighting device. The thread processing clamp comprises a bottom positioning plate, a guide core, a threading die component, a sleeve and a pull rod. The bottom positioning plate and the guide core are connected together through a hexagonal nut, the guide core is assembled on the bottom positioning plate and a through hole of the sighting device, the threading die component and the guide core are coaxially mounted, and the bottom positioning plate and the upper end of the sighting device are connected through a rolling stopper pin. Compared with the prior art, the thread processing clamp is reasonable in structure, convenient to clamp and accurate in positioning, and is low in maintenance cost, high in production efficiency and stable in quality of processed threads.
Description
Technical field
The utility model relates to machinery manufacturing technology field, is specifically related to the clamp for machining of screw thread on a kind of aviation apparatus sight.
Background technology
In modern Aviation industrial products, apparatus sight as shown in Figures 1 to 3, is a core part, and this part material is superior alloy steel (38CrMnAl), and it is high temperature resistant, wear-resistant, and cutting ability is good.Apparatus sight is special-shaped long shaft parts, and on it, the processing of M18-6g screw thread turning or pincers worker on lathe press the system of pulling to be all difficult to pulling, and its production efficiency is low and thread quality is very poor.
Summary of the invention
The purpose of this utility model is to provide the clamp for machining of screw thread on a kind of aviation apparatus sight, to overcome deficiency of the prior art.
To achieve these goals, the utility model is by the following technical solutions:
The clamp for machining of screw thread on a kind of aviation apparatus sight, comprise positioning plate, the guidance type heart, bolt die assembly, sleeve, tommy bar, described positioning plate and sight link together by hex nut, the guidance type heart is fitted in the through hole of positioning plate and sight, bolt die assembly and the guidance type heart are coaxially installed, and positioning plate adopts spline pin to be connected with sight upper end.
Described bolt die assembly and sleeve adopt the front end that lock-screw is connected and fixed, tommy bar is positioned at sleeve.
Compared with prior art, the utility model is rational in infrastructure, convenient mounting and clamping, accurate positioning, and its maintenance cost is low, production efficiency is high, machining screw steady quality.
