Technical field
The utility model relates to a kind of for drill jig device, in particular for line rail drill jig.
Background technology
The effect of machine tool guideway is the precision and the support that ensure workpiece or cutting tool path.Guide rail is divided into hard rail and line rail, and it is large that hard rail is mainly used in load, and intensity is high, is applicable to heavy cut, such as uses large cutter machining large mould, plant equipment; Line rail is mainly used in speed block, and precision is high, is applicable to high speed machine use, can high-speed cutting, such as processing miniature precision mould.Along with industrialized propelling, the use amount of lathe gets more and more, automaticity is also more and more higher, it is little that lathe is used for adding cutting output, the part that machining accuracy is high just needs to adopt this movement velocity block of line rail, and resistance to rolling is little, there is no creeping phenomenon, lubrication also facilitates, after long-time use, the guide rail that loss of significance is less, and for this problem line rail installation and the precision of lathe must be affected, produce center line rail normally outsourcing piece finished parts, for the location of line rail, install, adopt to rule on lathe bed at present, look for a little, the method of boring, the connecting hole that lathe bed is processed can offset correct position, and then the through hole adopting bolt to pass line rail screws in the screwed hole that lathe bed is processed, complete installation.This processing technology makes the machining accuracy in the hole on lathe bed depend on the technical merit of operator individual, when production scale expands, is difficult to the quality ensureing batch production.
Utility model content
The hole that the purpose of this utility model is to solve hole on the base of current hookup wire rail and line rail misplaces, the problem such as during drilling machining accuracy is not high, the utility model designs a kind of drill jig device, by solving the relative position in hole at bushing plate, effective solution borehole accuracy can be had not high, the problems such as constant are installed.
In order to achieve the above object, the technical solution of the utility model is: comprise clamp body, positioner, clamping device, bushing plate, drill bushing, bushing plate on line rail drill jig has the first groove and the second groove near both ends of the surface, alignment pin is provided with in an end of bushing plate, there is contiguous block end relative with alignment pin on bushing plate, contiguous block is bolted on bushing plate by two first, connecting plate is provided with hold-down bolt, the design pitch-row figure of joint line rail and the installation site of line rail on lathe bed again, bushing plate is first processed to portal and installs drill bushing again, by the first voussoir, second voussoir is pressed in the first groove and the second groove respectively.
In technique scheme, the architectural feature of workpiece of wanting that the selection of locating surface makes full use of completes location, which reduce the structure of fixture, make fixture simple, recycling alignment pin location, utilization voussoir clamp, the setting-out of the simple and effective solution of this method look for a little process connecting hole distance between precision low, the shortcoming that difficulty of processing is large.
Improve as the first step of the present utility model, in order to improve machining accuracy, the boss that bushing plate adopts with bedstead contact surface, which reduces the machined surface of bushing plate locating surface, can its positioning precision of available protecting.
Improve as second step of the present utility model, the first voussoir, the second voussoir have respectively the first screwed hole 3K, the second screwed hole 4K, directly screw in bolt respectively, directly ejected by voussoir during dismounting, this method is simple, laborsaving.
Improve as the 3rd step of the present utility model, can need to use briquetting to compress line rail by this hookup wire rail, on bushing plate, be also directly provided with the drill bushing of the solid apical pore of drilling processing briquetting for this reason, the corresponding line rail installing hole of the first drill bushing and the corresponding briquetting fixing hole of the second drill bushing.
