Description
Technical field
The utility model relates to electrical equipments to produce tooling, more particularly to a kind of breaker main shaft positioning pin boring positioning
Tooling.
Background technique
Currently, usually direct hand takes drilling machine opposite when boring dowel hole on breaker main shaft to install positioning pin
Breaker main shaft bores dowel hole with eyesight and experience, and the dowel hole drilled out is made to be in the position designed in advance as far as possible
On direction.But current artificial hand drill, disposably dowel hole can not be drilled or boring procedure in hand shaking situations such as, bore
Hole precision out is not high, and drilling quality is poor, and the dowel hole typed it out every time is not uniquely, after influencing breaker main shaft
Continuous installation and work, in addition Manual drilling poor efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of breaker main shaft positioning pin hole drilling positioning fixtures, it can be ensured that drills out
The position and direction in hole meet the requirement designed in advance.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals:
Breaker main shaft positioning pin hole drilling positioning fixture, including for placing drilling machine mounting plate, for limiting installation
The limit plate of plate fixed angle, limit plate are equipped with arc-shaped limit hole, are equipped with and are used in front of limit plate on mounting plate
The location hole of limitation installation Board position.
Preferably, installation front edge of board is plane.
Preferably, mounting plate is made of A3 steel plate.
Preferably, location hole is arranged in mounting plate lower end.
The utility model has significant technical effect: by determining for mounting plate lower end due to using above technical scheme
Position hole covers outside breaker main shaft and locks on-board the circuit breaker by limit plate by bolt, and positioning tool is consolidated in two o'clock realization
It is fixed, drilling machine is placed on a mounting board, the position of drill bit is adjusted, drilling machine is powered, and drilling machine can be firmly adsorbed on
On mounting plate, position will not change in boring procedure, it is ensured that and the dowel hole drilled out is met the requirements, and improves drilling quality,
And the dowel hole drilled out is unique, the efficiency raising of drilling.
Detailed description of the invention

Fig. 2 is the main view of Fig. 1.
Fig. 3 is the side view of Fig. 1.
Fig. 4 is the utility model embodiment use state main view.
The toponym that each number designation is referred in attached drawing is as follows: wherein 1-mounting plate, 2-limit plates, 3-limits
Hole, 4-location holes, 5-reinforcing ribs, 6-breaker main shafts, 7-sleeves, 8-breakers, 9-breaker input shafts, 10-spiral shells
Bolt, 11-drilling machines, 12-dowel holes.
Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing.
Embodiment
Breaker main shaft positioning pin hole drilling positioning fixture, breaker main shaft 6 are mounted on breaker 8 by sleeve 7, are drilled
Against the sleeve 7 for covering breaker main shaft 6, drill bit pierces the drill bit of machine 11 from the radial one end of sleeve 7, and is pierced by breaker main shaft
6, it is pierced by from the radial other end of sleeve 7, the formation of dowel hole 12.
As shown in Figs 1-4, including the mounting plate 1 for placing drilling machine 11, the limit for limiting 1 fixed angle of mounting plate
Position plate 2, limit plate 2 are welded on 1 lower end of mounting plate, and limit plate 2 is equipped with arc-shaped limit hole 3, and limit hole 3 is strip, can
Mounting plate 1 is locked after facilitating the angle for adjusting mounting plate 1.1 lower end of mounting plate, which is located in front of limit plate 2, to be equipped with for limiting installation
The location hole 4 of 1 position of plate.1 front end of mounting plate is plane.Mounting plate 1 is made of A3 steel plate, the company of limit plate 2 and mounting plate 1
It meets place and is equipped at least one piece of reinforcing rib 5, improve the connectivity robustness between mounting plate 1 and limit plate 2.
When installation, by positioning tool close to breaker main shaft 6, by 4 sets of location hole in 6 front end of breaker main shaft, until peace
1 front end of loading board heads on 7 axial end face of sleeve, and the front-rear position of mounting plate 1 determines at this time, rotates and installs around breaker main shaft 6
Plate 1, so that the angle of mounting plate 1 is adjusted, so that the drill bit alignment sleeve 7 for the drilling machine 11 being placed on mounting plate 1, passes through spiral shell
Bolt 10 successively penetrates rear and nut check in the screw hole of limit hole 3, breaker input shaft 9, so that 1 locking positioning of mounting plate be existed
On breaker 8, the position angle of mounting plate 1 is fixed non-adjustable at this time, and drilling machine 11 is placed on mounting plate 1, mixes up position
It sets, drill bit alignment sleeve 7, drilling machine 11 is powered, and can drill, there is the positioning and limit of mounting plate 1, entire boring procedure
The position of middle drilling will not change, and drilling quality can be improved.
Drilling machine 11 is bored using electromagnetism, therefore when drilling machine 11 is placed on mounting plate 1, and electromagnetism brill can firmly be sucked
On mounting plate 1,11 position of drilling machine be will not change in boring procedure, improve drilling quality.
In short, the above is only the preferred embodiment of the present invention, it is all according to present utility model application the scope of the patents institute
The equivalent changes and modifications of work should all belong to the covering scope of the utility model patent.
