Abstract

An encoder gear drilling tool comprises a square platform (1), a cylindrical ejector pin module (2), an L-shaped module (3), M4 x 20 inner hexagonal screws a (4), a flat washer (5), an elastic washer (6), M4 x 20 inner hexagonal screws b (7) and M8 x 35 bolts (8); the method is characterized in that: an encoder and a gear are connected to the square platform (1) through an M4 x 20 internal hexagonal screw a (4), a flat washer (5) and an elastic washer (6), a cylindrical ejector pin module (2) is connected to the square platform (1) through an M8 x 35 bolt (8), and an ejector pin on the cylindrical ejector pin module (2) is positioned with the gear to prevent the gear from rotating; and then the semicircular key of the L-shaped module (3) is clamped in the interval formed by the encoder and the gear, and the L-shaped module (3) is pressed on the square platform (1) by using an M4 multiplied by 20 internal hexagonal screw b (7). The invention changes the original drilling mode, can fix the encoder gear and is beneficial to protecting the encoder shaft.

Description

Encoder gear drilling frock
Technical Field
The invention belongs to the technical field of gear drilling tools, and particularly relates to an encoder gear drilling tool suitable for II-42 products.
Background
In recent years, the ZWA6002 product high-low position sensor manufactured by our company reflects that a large number of products have abnormal operation in azimuth and height due to the fact that an encoder in a high-low machine or a steering machine has a fault and output data jumps in the production debugging link and the using process of an army, and brings safety risk and potential performance hazard to the normal use of a whole cannon system. Because the encoder is an imported precise part, the encoder cannot be maintained after a fault occurs, and only can be integrally scrapped and replaced, thereby causing great economic loss. Based on the reasons, it is necessary to carry out attack and customs work on the assembly of the encoder, and by formulating optimization and improvement measures, the assembly quality of the encoder is improved, and the scrapping loss is reduced. Since the batch production of the ZWA6002 products from 2012 to 2015, numerical value jump conditions of high and low or orientation feedback data are reflected in final assembly debugging every year, and most of the numerical value jump conditions are caused by the faults of encoders in high and low machines and direction machines through inspection. In order to save the bottleneck of production cost, it is necessary to design and manufacture the encoder gear drilling tool.
Disclosure of Invention
The invention aims to solve the problems in the background technology and design an encoder gear drilling tool.
The invention relates to an encoder gear drilling tool which comprises a square platform 1, a cylindrical ejector pin module 2, an L-shaped module 3, an M4 x 20 inner hexagonal screw a4, a flat washer 5, an elastic washer 6, an M4 x 20 inner hexagonal screw b7 and an M8 x 35 bolt 8, wherein the square platform is provided with a plurality of holes; the method is characterized in that: an encoder and a gear are connected to the square platform 1 through an M4X 20 internal hexagonal screw a4, a flat washer 5 and an elastic washer 6, the cylindrical ejector pin module 2 is connected to the square platform 1 through an M8X 35 bolt 8, and an ejector pin and the gear on the cylindrical ejector pin module 2 are positioned to prevent the gear from rotating; the half-round key of the L-shaped module 3 is clamped in the interval formed by the encoder and the gear, and the L-shaped module 3 is pressed on the square platform 1 by using M4 multiplied by 20 internal hexagonal screws b 7.
The encoder gear drilling tool changes the original drilling mode, can fix the encoder gear to ensure that the encoder gear does not swing in the drilling process, and well protects the encoder shaft.
