Abstract
The utility model provides a drilling processing device for a through hole. The drilling processing device comprises a vertical plate, a bottom plate, an arced fixing stop pin, a drilling formwork, a drilling sleeve, a nut, a positioning pin, an internal hexagonal screw and an opening flat cushion. The drilling processing device is characterized in that the vertical plate is vertically welded on the bottom plate to form a fixture body; the arced fixing stop pin and the positioning pin are both connected with the vertical plate; the drilling formwork is fixedly connected to one end of the vertical plate through threads; the arced fixing stop pin is used for fixing, and comprises a mandrel on which an arc groove is arranged; threads are arranged at one end of the mandrel; and the mandrel is connected with a hexagonal nut through the open flat cushion; and the hexagonal nut and the opening flat cushion form a compressing device. With the adoption of the drilling processing device provided by the utility model, a workpiece can be assembled, fixed, positioned, drilled, milled and unloaded; the direction of a drill bit in drilling is controlled through the hardened arced fixing stop pin, so that the processing of some through holes can be perfectly implemented, and the production efficiency is greatly improved. The drilling processing device provided by the utility model is simple in structure, convenient and reliable in use, high in production efficiency, capable of being repeatedly utilized, and popularly applied to drilling the through hole.
Description
Technical field
The utility model relates to a kind of brill processing unit (plant) of through hole.
Background technology
A kind of locking pin-and-hole is arranged in the structure of automotive suspension hanger, is to run through with the spring piot bore portion.In the former processing since be the part run through, interrupted and the part cutting of drill bit, easily crooked, fracture, usually in the leaf spring pin-and-hole, penetrate the round steel of the similar material of suitable diameter, extract after the drilling, penetrate again when boring again and the rotary moving position, avoid original circular arc, both affect production efficiency, wasted again material.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming in the former technology and a kind of brill processing unit (plant) of reliable, reusable through hole is provided.
The technical scheme that its technical problem that solves the utility model adopts is to implement like this: a kind of brill processing unit (plant) of through hole mainly is comprised of riser, base plate, band circular arc fix stopper, bushing plate, drill bushing, nut, alignment pin, soket head cap screw, opening plain cushion; It is characterized in that: riser is vertically welded on the base plate, consists of clamp body; Be provided with band circular arc fix stopper fixing hole, alignment pin fixing hole on the riser; Interference fits is adopted in band circular arc fix stopper and hole, and alignment pin and hole employing interference fit are with circular arc fix stopper and alignment pin all to be connected with riser.Bushing plate is fixed on an end of riser by thread connection; Drill bushing and drill jig plate hole adopt interference fit; Band circular arc fix stopper plays fixation, and it comprises axle, and axle is provided with arc groove, and during boring, arc groove plays the guiding restriction.Axle one end has screw thread, and connects hex nut by the opening plain cushion, and hex nut and opening plain cushion form hold down gag; And hex nut outer-hexagonal circumscribed circle diameter is less than the large footpath with the circular arc fix stopper, with Fast Installation and dismounting workpiece in the situation that realizes not screwing off hex nut.
Can realize clamping location, drilling, discharging to workpiece by this device, utilize harden with the guiding problem of circular arc fix stopper control drill bit in drilling, the perfect processing that solves the part through hole is significantly enhanced productivity.
The utility model is simple in structure, and is easy to use and reliable, and production efficiency is high, and is reusable, generally is applicable to the brill processing of through hole.
Description of drawings
Fig. 1 is the cutaway view of structural front view of the present utility model;
Fig. 2 is structure top view of the present utility model.
Among the figure: 1. riser, 2. base plate, 3. band circular arc fix stopper, 4. bushing plate, 5. drill bushing, 6. hex nut, 7. alignment pin, 8. axle, 9. soket head cap screw, 10. opening plain cushion, 11. arc grooves.
The specific embodiment
As shown in the figure, a kind of brill processing unit (plant) of through hole mainly is comprised of riser 1, base plate 2, band circular arc fix stopper 3, bushing plate 4, drill bushing 5, nut 6, alignment pin 7, soket head cap screw 9, opening plain cushion 10; It is characterized in that: riser 1 is vertically welded on the base plate 2, consists of clamp body; Be provided with band circular arc fix stopper fixing hole, alignment pin fixing hole on the riser 1; Band circular arc fix stopper 3 adopts interference fits with the hole, and two alignment pins 7 adopt interference fit with the hole, all are connected with riser 1.Bushing plate 4 is fixed on an end of riser 1 by thread connection; Drill bushing 5 adopts interference fit with bushing plate 4; 3 fixations of band circular arc fix stopper, it comprises axle 8, axle 8 is provided with arc groove 11, during boring, 11 guiding of arc groove restriction.Axle 8 one ends have screw thread, and connect hex nut 6 by opening plain cushion 10, and hex nut 6 and opening plain cushion 10 form hold down gag; And hex nut 6 outer-hexagonal circumscribed circle diameters are less than the large footpath with circular arc fix stopper 3, with Fast Installation and dismounting workpiece in the situation that realizes not screwing off hex nut 6.
Can realize clamping location, drilling, discharging to workpiece by this device, utilize harden with the guiding problem of circular arc fix stopper control drill bit in drilling, the perfect processing that solves the part through hole is significantly enhanced productivity.
During use, workpiece is pressed the shown position clamping on band circular arc fix stopper 3, workpiece small hole is contained on the alignment pin 7, and hold down gag is screwed, and guarantees workpiece fully reliable location on device; After using radial drilling machine to finish boring by drill bushing 5, unclamp hold down gag, take off workpiece, finish the processing of this part through hole.
The utility model is simple in structure, and is easy to use and reliable, and production efficiency is high, and is reusable, generally is applicable to the brill processing of through hole.
