The invention relates to a positioning mould for welding processing. Aiming to overcome the technical problem that the position is not easy to align before spot welding connection is carried out on two large-scale chuck jaws at present, the invention provides the positioning mould for chuck jaw welding, and the positioning mould comprises two clamping pieces with uniform structures and is characterized in that the clamping pieces comprise square clamping seats; cuboid stand columns higher than the planes of the clamping seats are respectively arranged at four corners of the clamping seats; jackscrews are respectively arranged on two stand columns at one sides of the clamping seats, penetrate through the stand columns from the outer sides and point to the stand columns at the corresponding sides of the clamping seats; vertical semicircular convex columns are respectively arranged on the inner surfaces of the two stand columns at the other sides of the clamping seats; center holes are formed at the centers of the clamping seats; and when a chuck jaw is clamped between the two clamping pieces through the stand columns on the two clamping pieces in the opposite directions, a screw rod penetrates through the center holes on the two clamping seats and two ends of the screw rod are respectively locked by adopting nuts. The mould is simple in structure, simple and convenient in operation and capable of guaranteeing stable welding precision.
Description
Technical field
The present invention relates to a kind of positioning clamping fixture when welding processing, be specifically related to a kind of claw welding positioning clamping fixture.
Background technology
When the screw thread of processing vertical lathe, the large-scale chuck jaw of sleeping carriage, for the precision of the chuck jaw that guarantees to process is consistent, generally adopt Special mould to process.Because the processing number of packages of general large-scale chuck jaw is less, if every kind of chuck jaw all carries out matrix design, then causes the matrix design high cost.Mostly be man-hour to process simultaneously two chuck jaws are spot-welded together adding at present, before spot welding, need two chuck jaws are carried out the position centering, guarantee that the welding position of two chuck jaws is accurate.And in the centering process, if there is not special-purpose positioner, two chuck jaws are difficult to guarantee the accurate of position.
Summary of the invention
For overcome at present carry out two large-scale chuck jaw spot welding connect before its position be difficult for the technical problem of centering, the invention provides a kind of rational in infrastructurely, easy and simple to handle, can guarantee the dog plate welding positioning clamping fixture of the accurate centering of two dog plates.
The technical solution used in the present invention is: dog plate welding positioning clamping fixture, comprise two fasteners that structure is consistent, it is characterized in that: described fastener comprises a square deck, four jiaos at deck are respectively equipped with the cuboid column that exceeds the deck plane, two columns in deck one side are respectively equipped with jackscrew, and jackscrew passes the column that column points to the deck respective side by the outside; Two column inner surfaces at the deck opposite side are respectively equipped with vertical up and down semicircle projection; The center of deck is provided with centre bore, and when the column subtend on two fasteners is stuck in chuck jaw between two fasteners, screw rod passes the centre bore on two decks, and nut check is adopted respectively at the screw rod two ends.
Centre bore on the described deck, centre bore are taper hole.
Be provided with spheric washer in the described vertebral foramen.
Beneficial effect of the present invention is: simple in structure, low cost of manufacture, adjustment easy and simple to handle, easy can be crossed and be guaranteed accurately to carry out the position centering between the two card masters, has guaranteed stable welding precision.This dog plate welding positioning clamping fixture can be widely used in the process operation of dog plate.

The specific embodiment
The present invention will be further described below in conjunction with drawings and Examples.
As shown in Figure 1, chuck jaw comprises claw arm 1 and claw 2, and claw arm 1 is connected into L-type with claw 2 vertical weldings.
As shown in Figure 2, be provided with semicircle groove 3 in the bottom of claw arm 1.
Fig. 3 is the top view of chuck jaw, Fig. 4 be among Fig. 3 A-A to cutaway view, can find out that in conjunction with Fig. 3, Fig. 4 chuck jaw is a L-type cube by Fig. 1, Fig. 2, be provided with semicircle groove 3 in the bottom of claw arm 1, required processing is on the surface of claw 2 and the cell wall of semicircle groove 3 processes screw thread.
As shown in Figure 5, chuck jaw to be processed comprises the first chuck jaw 4-1 and the second chuck jaw 4-2, for guaranteeing that machining accuracy is consistent, need to the first chuck jaw 4-1 and the welding of the second chuck jaw 4-2 subtend, make its semicircle groove 3 subtends separately close up rear formation round cavity.
As shown in Figure 5, for guaranteeing the position centering of the first chuck jaw 4-1 and the second chuck jaw 4-2, the welding positioning clamping fixture that this invention provides comprises two fasteners that structure is consistent, and two fasteners are positioned at the two ends of chuck jaw.
As shown in Figure 5, fastener comprises a square deck 5, in conjunction with shown in Figure 6, is respectively equipped with the cuboid column 6 that exceeds the deck plane at deck 5 four jiaos.
Such as Fig. 5, shown in Figure 6, the two ends of the claw arm of the first chuck jaw 4-1 and the second chuck jaw 4-2 lay respectively in the space that two columns 6 on the deck 5 surround, claw 2 stretches out fastener by the space between two columns, connects and pass through the nut check at screw rod 7 two ends between two fasteners by screw rod 7.
As shown in Figure 6, be respectively equipped with jackscrew 8 at two columns 6 of deck 5 one sides, jackscrew 8 passes the column that column points to the deck respective side by the outside.
Fig. 7 is in conjunction with shown in Figure 6, is respectively equipped with vertical up and down semicircle projection 9 at two column 6 inner surfaces of deck 5 opposite sides.
During concrete the use, such as Fig. 5, shown in Figure 6, step is as follows:
(1) the first chuck jaw 4-1, the second chuck jaw 4-2 and two fasteners are put well according to shown position.
(2) with screw rod 7, nut 10 chuck jaw and fastener are blocked gently, card is too not tight.
(3) jackscrew 8 is held out against gently, the top is too not tight.
(4) repeat (2), (3) step cycle chucking.
(5) check that with 0.03 clearance gauge the part contact-making surface reaches and the contact-making surface of mold R, make distance numerical value up to specification between it.
(6) part two sides spot welding.
(7) unload mold.
As shown in Figure 7, two column 6 inner surfaces in deck 5 one sides are respectively equipped with vertical up and down semicircle projection 9, the effect of this projection 9 is when adjusting jackscrew 8, chuck jaw can rotate around semicircle projection 9, alleviate the spinning force of jackscrew 8, also be conducive to simultaneously the movement of chuck jaw, make the accurate centering in two chuck jaw positions.
As shown in Figure 5, for making screw rod 7, nut 10 two fasteners and chuck jaw are firmly locked, be provided with spheric washer 11 in the centre bore on the deck 5, correspondingly its centre bore is designed to taper hole.
