Abstract

The utility model relates to a flange lug drilling jig. The flange lug drilling jig comprises a lower plate, a vertical plate and an upper plate, wherein the lower end of the vertical plate is connected with the lower plate, the upper end of the vertical plate is connected with the upper plate, the middle part of the vertical plate is connected with an extending screw, and a nut and an opening gasket are arranged on the end head of the screw; a spring pin is arranged at the joint of the vertical plate and the lower plate, and is inserted into a pin hole of the upper plate to position the upper plate; the upper plate is fixedly provided with a drill bushing, and the drill bushing is directly opposite to the extending screw in the middle of a square plate. The flange lug drilling jig has the advantages that the spring pin is used, and thus the positioning precision is improved; the spring pin is cheaper than a cylindrical pin, and thus the machining cost is lower; a hole of the spring pin needs to be drilled in a matched mode, and thus the positions of components before dismounting can be kept when the jig is assembled again, and the production difference after the jig is repaired is effectively reduced; the service life of the new jig is prolonged by four times compared with that of an old jig, and the working efficiency is improved by six times; the positioning precision is higher, and the jig components are convenient to replace; the machining precision is high, and the consistency of products is improved.

Description

Flange lug boring grab
Technical field
The utility model relates to Machining Technology field, particularly a kind of flange lug boring grab.
Background technology
The boring grab using at present, its grip device difficulty is large, and the clamping of alignment pin is slow, the compression mode of nut is comparatively loaded down with trivial details, and the compression of nut causes labour intensity large, and has certain potential safety hazard clamping workpiece speed slow, Heavy Weight, is not easy to resettlement, and service life is short.
Utility model content
The purpose of this utility model is just to provide a kind of reduction fixture processing cost, reduces Fixture assembly degree-of-difficulty factor, accelerates clamping workpiece speed, increases fixture intensity, improves the flange lug boring grab in service life.
Solution of the present utility model is such:
A flange lug boring grab, comprises base plate, riser, upper plate, and described riser lower end is connected with base plate, and riser upper end is connected with upper plate, is connected with the screw rod stretching out at the middle part of riser, at described screw end head, is provided with nut and opening pad; Described riser and lower plate junction are provided with spring catch, and the pin-and-hole that described spring catch inserts upper plate positions upper plate; Described upper plate is fixed with drill bushing, the screw rod that described drill bushing stretches out over against square plate middle part.
Technical scheme also comprises more specifically: on described riser, be fixed with two alignment pins, for positioning workpieces position.
Further: described base plate has base plate positioning straight mouth, the lower end of described riser is connected with base plate positioning straight mouth, uses bolted.
Further: described upper plate has upper plate positioning straight mouth, the upper end of described riser is connected with upper plate positioning straight mouth, uses bolted.
Further: described drill bushing and upper plate structure with bolts.
The utility model has the advantages that and used spring catch, improved the precision of location; Due to the spring catch economy more next than straight pin, so processing cost is lower; Because joining brill in the hole of spring catch, so when refitting fixture, can keep dismantling the position between front parts, effectively reduce the production difference after fixture is repaired; The new fixture life-span is compared four times of lifes with old fixture, operating efficiency improves six times; Positioning precision is higher, is convenient to fixture parts with changing; Machining accuracy is high, improves the homogeneity of product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is figure iron left view.
Fig. 3 is the top view of Fig. 1.
In accompanying drawing, 1, base plate; 2, riser; 3, upper plate; 4, drill bushing; 5, spring catch; 6, M8 soket head cap screw; 7, M6 soket head cap screw; 8, nut; 9, screw rod; 10, opening pad; 11, alignment pin.
The specific embodiment
After the utility model riser 2 processes, squeeze into alignment pin 11; Base plate 1 processes after positioning straight mouth, and riser 2 is fixed in positioning straight mouth, fastening by M8 soket head cap screw 6; Upper plate 3 in like manner, first processes positioning straight mouth, fastening by M8 soket head cap screw 6; Joining drill diameter, be 8 hole afterwards, squeeze into spring catch 5, location upper plate 3; Drill bushing 4 is embedded in upper plate 3, fastening with M6 soket head cap screw 7; During clamping workpiece, alignment pin 11 positioning workpieces positions, screw rod 9, through riser 2, utilizes opening pad 10 with nut 8 workpiece pressings.
Thereby the utility model flange needs after installing to tighten workpiece pressing by coordinating between nut and screw rod, inserts open washer sheet between workpiece and nut, not only reduces nut and tightens the number of turns (labour intensity weakens), also better presses and scrapes workpiece (pad effect).On riser, the spacing of two alignment pins in strict accordance with the spacing fabrication and installation of workpiece pilot hole, not only plays positioning workpieces effect, and the effect that can also detect pitch of holes on workpiece has certain cubing effectiveness.With bolts between upper plate and riser, the mode of spring catch location, this mode is convenient to the exchange of drill bushing, has interchangeability, by changing upper plate, just can bore the screwed hole (becoming another set of fixture) on flange tower; The steel plate thickness that frock is used is large, and the good rigidly of integrated tooling, is not easy to cause the deviation in position, hole, aperture because of factors such as vibrations.
