Abstract
A flange lug drilling jig comprises a lower plate, a stand plate and an upper plate. The lower end of the stand plate is connected with the lower plate, the upper end of the stand plate is connected with the upper plate, the middle of the stand plate is connected with an extending screw, and the end of the screw is provided with a nut and an opening gasket. A spring pin is arranged at the connection position between the stand plate and the lower plate, and is inserted into a pin hole in the upper plate to position the upper plate. The upper plate is fixedly provided with a drilling cover, and the drilling cover is right 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 therefore the positioning precision is improved; the spring pin is cheaper than a cylindrical pin, and therefore the machining cost is low; a hole of the spring pin needs to be drilled in a matched mode, and therefore 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 five times that of an old jig, and the working efficiency is improved by six times; the positioning precision is higher, and the jig components can be replaced conveniently; the machining precision is high, and the consistency of products is improved.
Description
Technical field
The present invention 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.
Summary of the invention
Object of the present invention 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 invention is such:
A flange lug boring grab, comprises lower plate, riser, upper plate, and described riser lower end is connected with lower 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.
Advantage of the present invention is to have used spring catch, has 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 invention.
Fig. 2 is figure iron left view.
Fig. 3 is the top view of Fig. 1.
In accompanying drawing, 1, lower 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 riser 2 of the present invention processes, squeeze into alignment pin 11; Lower 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 flange of the present invention 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.
