Description
Technical field
The present invention relates to industry manufacture field, especially a kind of pressure piping inlet flange special fixture.
Background technology
Pressure piping inlet flange, has multistation and has taper seat, and need on taper seat, process different types of inclined hole.When multistation taper seat Drilling operation, owing to being difficult to occupy correct Working position between process tool and workpiece, make difficulty of processing larger.Pressure duct inlet flange as shown in Figure 1, difficulty of processing is the processing of 8-φ 11 holes and corresponding counterbore φ 17, because process on the conical surface, clamping workpiece difficulty, workpiece and cutter are between drill bit, to be difficult to form correct position relationship, and belong to multistation processing, processing the quick and precisely location in next hole behind a hole and being also needs the problem that solves in processing.For guaranteeing crudy.The efficiency that improves workpiece location and clamp, needs design specialized drilling clamp to complete the processing of 8-φ 11 holes and corresponding counterbore φ 17.Before drilling processing 8-φ 11 holes and corresponding counterbore φ 17, need complete workpiece appearance profile and endoporus processing.On 30 ° of inclined-planes, not before turning, complete the drilling processing in φ 21 holes, to avoid the difficulty that boring brings to processing on inclined-plane, and φ 21 holes are using the processing locating hole as 8-φ 11 holes and corresponding counterbore φ 17.
Summary of the invention
The object of the invention is to propose a kind of flange special fixture, it has accurate positioning, easy for installation, simple in structure, feature with low cost.
The technical scheme that the present invention solves its technical problem employing is: this fixture comprises basic part, handle, rotating disk, bushing plate, Quick-change drill bush, screw rod, swivel nut; Basic part is bolted on lathe, and Quick-change drill bush is connected on bushing plate, and bushing plate is connected on basic part by bearing pin; Screw rod one end attaching nut, other end connection opening nut; Chamfered edge pin is connected on rotating disk, and swivel nut and rotating disk are sleeved on screw rod, and is fixed on basic valency; Handle and rationed marketing is connected on swivel nut, limited post is connected on basic part.
The invention has the beneficial effects as follows: adopted hinge type bushing plate, can to workpiece, install and remove easily; Utilize the conical surface, to rationed marketing, the multistation of workpiece is realized to accurately and fast station adjustment, and utilize edge cam mechanism and spring action to realize the pulling out and inserting rationed marketing to workpiece calibration.The design compact overall structure of this drilling machine special fixture, easy to use and reliable, manufacturing cost is lower.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated: as shown in Figure 2, this fixture comprises basic part 1, handle 2, rotating disk 3, bushing plate 6, Quick-change drill bush 7, screw rod 9, swivel nut 15; Basic part 1 is bolted on lathe, and Quick-change drill bush 7 is connected on bushing plate 6, and bushing plate 6 is connected on basic part 1 by bearing pin 5; Screw rod 9 one end attaching nuts 8, the other end connects slotted nut 16; Chamfered edge pin 10 is connected on rotating disk 3, and swivel nut 15 and rotating disk 3 are sleeved on screw rod 9, and is fixed on basic valency 1; Handle 2 and rationed marketing 12 is connected on swivel nut 15, limited post 4 is connected on basic part 1.
During work, for making workpiece, on fixture, accurately locate, having designed the rotating disk of sequence number 3 and the screw rod of sequence number 9 in Fig. 2 is linked together and is become component by interference fit, and load onto the chamfered edge pin of sequence number 10 thereon, workpiece is arranged on this component, on workpiece last operation machining hole φ 21 coordinate with the chamfered edge pin of sequence number 10, inner hole of workpiece φ 32.3 and end face thereof coordinate with 9 component with sequence number 3, form the locate mode of Position with One Plane and Two Holes, can guarantee preferably the positioning relation of workpiece and clamp body.After having located, with the nut of sequence number 8, clamp.For making centerline hole to be processed and bit central line parallel on workpiece, on basic part 1, designed one and be the installed surface of 30 ° with basic part bottom surface, when the component of sequence number 3 and 9 is arranged on this installed surface, the hole heart line in the wherein hole on workpiece is just in time vertical with basic part bottom surface, with drill bit axis parallel, make workpiece occupy correct Working position.
Cutter guiding device cloth is spatially set up, and adopts hinge type bushing plate, can workpiece install and processing after dismounting time, avoid interfering with bushing plate.The guiding device of cutter is comprised of following part: sequence number 7 is Quick-change drill bush, and its effect is to process behind φ 11 holes at workpiece, 17 counterbore in the processing of fast changeable drill bushing; Sequence number 6 is bushing plate, can be around the bearing pin rotation of sequence number 5, to facilitate workpiece mounting or dismounting; Sequence number 4 is spacing pin, and the position of the bushing plate of sequence number 6 is located accurately, has hold-down bolt to be fixed bushing plate on it.
Because drilling processing 8-φ 11 holes and corresponding counterbore φ 17 can not complete in the one-time positioning of workpiece, belong to multistation processing work, designed the quick-replaceable station apparatus of workpiece for this reason.The calibration taper hole that has 8 radial equipartitions on the circumference of rotating disk 3, the installing hole that chamfered edge pin 10 is installed on this taper hole and rotating disk 3 has position relationship accurately, to guarantee that there is correct position relationship in the 8-φ 11 of processing and the hole of operation processing above.Sequence number 12 is to rationed marketing, and its front end conical surface coordinates with the taper hole of sequence number 3, has limited the circumference free degree of rotating disk 3, because sequence number 3 and workpiece are fixed together, and then has limited the circumference free degree of workpiece.Before boring, rationed marketing 12 is inserted under the effect of spring force in the calibration taper hole of people's rotating disk 3, reversion handle 2, swivel nut 15 is locked on clamp body rotating disk 3 by the opening nut of sequence number 16.After boring, forward handle 2 unclamps rotating disk, edge cam on swivel nut 15 will be extracted rationed marketing 12 by the pin of sequence number 14 simultaneously, thereby discharge the circumference free degree of rotating disk 3, then can carry out calibration, until rationed marketing 12 is inserted to second taper hole of people again, after locking, just can carry out the processing in second hole.
