Problems solved by technology

But at the same time, there is another problem, that is, there are 3 to 6 holes on the same boss. Due to the allowable positional error of the bottom hole in the processing, when a guide hole is aligned with a bottom hole of the casing, the other holes will not be aligned. Misalignment, so every time a threaded hole is processed, the worker must loosen the connection between the tapping template and the casing, repeat the preparatory work for tapping the first hole, and complete the tapping of all holes in turn
In this case, when tapping a group of holes on the end surface of a boss, the relationship between the auxiliary work time and the working time is 2:1. The total time is about 40-60 minutes for each group, and the operation is laborious and time-consuming.
In order to operate conveniently and quickly, there is no experience to learn from after investigation, and the efficiency of the tapping process is low, which will affect the normal progress of the entire scientific research task

Embodiment Construction

[0030] The present invention will be further described below in conjunction with embodiment.

[0031] see figure 1 The present invention comprises a drill formwork 1 and a baffle plate 3 arranged on the drill formwork 1, the shapes of the drill formwork 1 and the baffle plate 3 are consistent, four guide holes are provided on the drill formwork 1 and the baffle plate 3, and the drill formwork 1 and the baffle plate 3 are provided with four guide holes. The guide holes of the baffle plate 3 correspond to each other, and the position of the guide hole corresponds to the position of the bottom hole of the boss that needs to be tapped in the casing. A corresponding middle hole is opened in the middle position of the drill template 1 and the baffle plate 3. The drill template 1 and the baffle plate 3 A guide sleeve 2 is provided in the guide hole of the plate 3, and the guide sleeve 2 is arranged as an intermediate step structure, and the step position is located between the drilli...

Abstract

The invention discloses a tapping tool for grouped threaded holes, and aims to reliably position and press, reduce the labor intensity and improve the tapping efficiency. The adopted technical scheme is that the tool comprises a drill plate and a baffle plate, wherein the drill plate and the baffle plate have consistent shapes and are both provided with guide holes and middle holes; a guide sleeve is arranged in the guide holes and is provided with an axial through hole; the position of the through hole corresponds to the position of a bottom hole of a case; the guide sleeve can move horizontally in the guide holes; a bolt is arranged in the through hole of the guide sleeve; one end of the bolt extends into the bottom hole of a boss of the case, and the other end of the bolt extends out of the through hole of the guide sleeve; a step-shaped positioning pin is arranged in the middle holes; a small end of the positioning pin extends into the middle holes, and big end of the positioning pin can be inserted into the positioning hole in a boss surface of the case and is axially provided with a pressing plate; the positioning pin and the pressing plate are provided with axial threaded holes; a bolt is arranged in the threaded holes and penetrates through the threaded holes of the positioning pin and the middle holes of the baffle plate; the entire device can be positioned and tightly pressed on the case through the nut.

Description

technical field [0001] The invention relates to a tool for tapping, in particular to a tool for tapping grouped threaded holes. Background technique [0002] Due to the large receiver there are multiple sets of holes that need to be tapped in different directions. When tapping the side end face of the casing, the worker first places the tapping template on the end face of the boss, and then inserts the tap into a guide hole on the tapping template, and the guide cone at the front end of the tap will automatically find the center of the corresponding bottom hole , while maintaining this state, fasten the template and the receiver to complete the tapping of a hole. But at the same time, there is another problem, that is, there are 3 to 6 holes on the same boss. Due to the allowable positional error of the bottom hole in the processing, when a guide hole is aligned with a bottom hole of the casing, the other holes will not be aligned. Misalignment, so every time a threaded ho...
