Abstract
The utility model provides a breaker pull rod drilling positioning tool device which comprises a positioning device and an anvil. The positioning device comprises a base which is provided with a positioning cover. The upper surface of the base and the lower surface of the positioning cover are provided with V-shaped grooves, the middle of the base is provided with a positioning hole for a positioning pin to penetrate through, the middle of the positioning cover is provided with a through hole coaxial with the positioning hole, the diameter of the through hole is the same as the diameter of the positioning hole, and the positioning cover is further provided with a punching hole which is used for the anvil to penetrate through in the punching process. The positioning pin is used for fixing a pull rod into the V-shaped groove of the base, the outer surface of the pull rod is not damaged, weight is low, and moving is convenient. A positioning tool is used so that the base, the positioning cover and the pull rod can be fixed, the pull rod is prevented from rotating and sliding back and forth, the drilling perpendicularity is ensured, positioning precision is high, operation is simple and convenient, and the requirement for the drilling skill level of an operator is low. A position is fixed for punching through the positioning hole and the punching hole of the tool, the punching position for pull rod drilling can be simply and accurately positioned without measurement, working time is reduced, and working efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of circuit breaker tie rod hole drilling positioning fixture device.
Background technology
install the work of pivot pin equipotential sheet additional owing to carrying out circuit breaker tie rod, need hole perpendicular to former pivot pin central axis place, bore position and big or small secundum legem value.Need the good size of drill hole amount, pull bore position at circuit breaker tie rod by slide measure and Steel Ruler, stamp sample dotting punch, with bench drill on pull bar by playing dotting punch boring.Mainly there is following problem in operation like this:
If 1, due to rod material be aluminium fixture can defeature face, so should not directly clamp pull bar with instruments such as bench vices, and bench vice is heavier should not move, and can only hold the air cylinder part of pull bar bottom and artificially fix, fixed form is insecure.
2, carry out dimensional measurement stroke position, hole with slide measure and the manual range estimation of Steel Ruler, because workpiece is cylindric, location and borehole accuracy require high, and operator measures and boring level of skill affects large on product qualified rate.
3, when boring vibration of workpiece and the fixing not firm meeting of column type workpiece cause hole perpendicularity and size to have deviation, can not ensure with former pivot pin central axis, all at same plane and parallel, easily to produce waste product.
4, in practical operation, spend the time in measurement size and line more, inefficiency.
Summary of the invention
The utility model improves the problems referred to above, the technical problems to be solved in the utility model be existing circuit breaker tie rod install pivot pin additional and hole adopt operation easily damage pull bar surface, precision is not high and efficiency is low.
Specific embodiments of the present utility model is: a kind of circuit breaker tie rod hole drilling positioning fixture device, comprise positioner, alignment pin and sample punching, described positioner comprises base, described base upper surface is provided with the first V-type groove, described base middle part is provided with the locating hole passing for alignment pin, described base is provided with locating cover, described locating cover lower surface is provided with the second V-type groove corresponding with the first V-type groove, locating cover middle part is provided with through hole coaxial with locating hole and that diameter is identical, is also provided with the dotting punch hole of at the moment passing in a state of excitement for sample on described locating cover.
Further, described sample punching is made up of the screw tap being threadedly connected in axis body.
Compared with prior art, the utlity model has following beneficial effect:
1, use auxiliary pivot pin that pull bar is fixed in base V-type groove, to pull bar outer surface not damaged, and base is lightweight with locating cover, convenient mobile.
2, use positioning tool, utilize auxiliary pivot pin firm banking, locating cover and pull bar, prevent that pull bar from rotating and front and back slip, guarantee borehole perpendicularity, positioning precision is high, simple to operation, less demanding to operator's level of skill of holing.
3, firm being placed on bench drill workbench stablized by cylindric pull bar by recessed bases and auxiliary pivot pin, and boring positioning precision is high, locates qualification rate and can reach 100% after employing positioning tool.
4, carry out dotting punch by pivot pin locating hole and the asessory shaft pin-and-hole fixed position of frock, just need not measure the simply accurately dotting punch position of positioning tie bar Drilling operation, the activity duration reduces, and operating efficiency greatly improves.
5, adopt the positioning sample punching of built-in dismantled and assembled tapping, be convenient for changing the drift of wearing and tearing.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Fig. 1～2, a kind of circuit breaker tie rod hole drilling positioning fixture device, comprise positioner, alignment pin 30 and sample punching 40, described positioner comprises the locating cover 20 on base 10 and setting and base, described base 10 upper surfaces are provided with the first V-type groove 110, described base 10 middle parts are provided with the locating hole 120 passing for alignment pin 30, locating cover 20 lower surfaces are provided with the second V-type groove 210 corresponding with the first V-type groove, locating cover 20 middle parts are provided with through hole 220 coaxial with locating hole and that diameter is identical, on described locating cover, be also provided with the dotting punch hole 230 of at the moment passing in a state of excitement for sample.
The dotting punch hole 230 of locating cover 20 and the centre distance of through hole 220 are the centre distance in the former pin hole of circuit breaker tie rod 100 and hole to be processed.
When use, circuit breaker tie rod 100 is put between the first V-type groove 110 and the second V-type groove 210, and on locating hole 120 that alignment pin 30 is passed, circuit breaker tie rod 100 and through hole 220, alignment pin 30 diameters are consistent with locating hole 120 and through hole 220.
Complete behind location until circuit breaker tie rod 100, sample punching is put into the location of hole, dotting punch hole 230, sample rushes 40 and can be made up of the screw tap being threadedly connected in axis body.Finally take off locating cover 20, the circuit breaker tie rod 100 that completes boring location is placed under drill bit, now circuit breaker tie rod 100 is still fixed on base 10 under the effect of alignment pin 30.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
