Abstract

The utility model provides a turning attachment of remodeling fast belongs to the machinery processing technology field. These anchor clamps comprise base, holding ring, pressure plate assembly, screw, gland, the base is by disc, pillar and upward disc welding formation down, 4 classs of branch bolt holes are joined in marriage to disc and the contact of lathe workstation on the lower disc down, fix the base on the workstation through 4 bolts, go up the disc and pass through pin and holding ring accurate positioning, fix the holding ring on last disc through the screw, it has individual keyway to be used for installing pressure plate assembly upward to open on the disc, 4 individual pillar will be gone up to prop up between disc, the lower disc and compress tightly pressure plate assembly when enough spaces are used for installing the part, the gland compresses tightly the part at the part up end, improves the part rigidity, vibrates when preventing the parts machining atress. The utility model provides a longer drum barrel class part clamping alignment of radials overhang difficulty, different specification parts of the same type change anchor clamps cycle length, problem that special fixture manufacturing cost is high.

Description

One is remodeled lathe fixture fast

Technical field

The utility model belongs to Machining Technology, is specifically related to one and remodels fast lathe fixture.

Background technology

In aircraft engine slewing parts processing and manufacturing, for improving the performance of engine, meet work requirements, need by the method for welding, several disk-like accessories are formed bulging cylinder, carry out inside and outside profile precision work again, disk-like accessory outstanding with disc in work-ing life is stretched all longer to raise the efficiency, and diameter of bore is less, looks for clamping during drum tube kind part Vehicle Processing and just brings difficulty. Causing unit clamp complex structure, manufacturing expense height, the different size part exchanging fixture cycle of the same type is long. This type of problem perplexs aircraft engine drum tube kind part processing and manufacturing for a long time, and class of remodeling fast fixture receives much concern always.

Summary of the invention

For the problems referred to above, the utility model object is to provide a kind of drum tube kind part Vehicle Processing fixture, can realize part Fast Installation and just look for, and realizes when processing different size part of the same type changing fixture fast.

The utility model one is remodeled lathe fixture fast, is made up of base, retaining ring, pressing plate assembly, screw, gland; Base is formed by lower disc, pillar and the welding of upper disk; Lower disc contacts with Lathe bench, lower disc is joined 4 grades and divides bolt hole, is fixed on the table by base by 4 bolts; Upper disk is accurately located by pin and retaining ring, is fixed on upper disk by screw by retaining ring; Upper disk has a keyway for installing pressing plate assembly; 4 pillars will support clamping platen assembly when enough spaces are used for installing part between upper disk, lower disc; Gland is at part upper surface compressing component, it is to increase part rigidity, prevents part processing from vibrating by during power.

Same clamp base can configurable number retaining ring as required, it may also be useful to time change the retaining ring corresponded according to processed accessory size.

Pressing plate assembly sliding into keyway along keyway to dish heart direction till inner side when installing part, be placed on retaining ring by part, then along keyway, pressing plate assembly is slid into keyway outermost, part is fixed by tightening nut.

The utility model is mainly used in a new generation's aircraft engine drum inside and outside profile Vehicle Processing of tube kind part, solves disc and hangs and stretch the problem that longer bulging tube kind part clamping looks for positive difficulty, different size part exchanging fixture cycle length of the same type, unit clamp manufacturing cost is high. By arranging pillar, locating ring structure can be dismantled, eliminate the generation of above-mentioned phenomenon, drastically reduce the area the Operational preparation time, reduce unit clamp manufacturing cost, meet the process requirements of bulging barrel part. To the lifting of a new generation's aircraft engine, internal combustion turbine manufacturing technology level, there is the meaning of reality. Can promote the use of in similar part, there is suitable reference and wide application prospect.

Embodiment

Embodiment 1

One is remodeled lathe fixture fast, is made up of base 1, retaining ring 2, pressing plate assembly 3, screw 4, gland 5; Base 1 is welded by lower disc 6, pillar 7 and upper disk 8 and is formed; Lower disc 6 contacts with Lathe bench, lower disc 6 is joined 4 grades and divides bolt hole, is fixed on the table by base 1 by 4 bolts; Upper disk 8 is accurately located by pin and retaining ring 2, is fixed on upper disk 8 by screw 4 by retaining ring 2; Upper disk 8 has 6 keyways for installing pressing plate assembly 3; 4 pillars 7 will support clamping platen assembly 3 when enough spaces are used for installing part between upper disk 8, lower disc 6; Gland 5 is at part upper surface compressing component, it is to increase part rigidity, prevents part processing from vibrating by during power. Retaining ring schematic diagram is as shown in Figure 4. As shown in Figure 1, base structural representation is as shown in Fig. 2 Fig. 3, and retaining ring schematic diagram is as shown in Figure 4, Figure 5 for present clip structural representation.

Same clamp base 1 can configurable number retaining ring 2 as required, it may also be useful to time change the retaining ring 2 corresponded according to processed accessory size.

Pressing plate assembly sliding into keyway along keyway to dish heart direction till inner side when installing part, be placed on by part on retaining ring 2, then along keyway, pressing plate assembly is slid into keyway outermost, part is fixed by tightening nut.

The utility model uses step as follows:

1. first by fixture integral hoisting to, on platen, looking for positive lower disc 6 cylindrical benchmark band, it may also be useful to 4 bolts by fixing for base 1 on the table.

2. gland 5 is unloaded, pressing plate assembly is slid into away from retaining ring 2 along keyway 10.

3. being installed to by part on retaining ring 2,6 pressing plate assemblies are slid into keyway outermost along keyway 10 by the space between 4 pillars.

4. gland 5 is arranged on part upper surface, compressing component.

5. look for positive part according to processing request, it may also be useful to 6 pressing plate assemblies are compressed by spanner, process, as shown in Figure 6.

6. change different size part and add man-hour, do not change clamp base, former retaining ring is unloaded, change dimension retaining ring and can carry out part installation processing, as shown in Figure 7.

Fixture of the present utility model has been successfully applied to the inside and outside profile operation of smart car that certain batch is produced part, obtain satisfactory success, achieve great economic benefit and social benefit, the Vehicle Processing of other drum tube kind part there is good reference function, expand user demand and scope, huge economic benefit and technique effect can be createed.
