Detailed description of the invention
As seen in figures 3-6, is fitted in upper surface by the upper surface of crankshaft bearing cap 1 and crankshaft bearing cap 22, two songs
The bolt hole that runs through of axle bearing lid should be concentric.The one of which that mandrel 1 loads two crankshaft bearing caps is run through bolt
Kong Zhong, takes on nut 1 by band and band shoulder nut 37 is tightened on the screw thread that mandrel 1 two ends are exposed respectively, band shoulder nut 1
With the lower surface that the shoulder of band shoulder nut 37 is close to two crankshaft bearing caps.Mandrel 24 is loaded two crankshaft bearing caps another
Group runs through in bolt hole, band is takeed on nut 26 and band shoulder nut 48 is tightened on the screw thread that the two ends of mandrel 24 are exposed respectively,
The shoulder of band shoulder nut 26 and band shoulder nut 48 is close to the lower surface of two crankshaft bearing caps.
The body two ends of mandrel 1 are male threaded end 1 and male threaded end 2 302, and body is provided with location division
One 303 and location division 2 304.This body diameter of mandrel 1 is 41mm, and the external diameter of location division 1 is Φ 42(0-0.03),
The external diameter of location division 2 304 is Φ 42(0-0.03).Two on crankshaft bearing cap 1 and crankshaft bearing cap 22 run through bolt
Actual processing dimension Φ 42 in hole, therefore uses two sections of sizes to mandrel 1 when design, and the shortest mandrel (is equivalent to
Two pieces crankshaft bearing covers two and runs through bolt hole two ends insertion connection alignment pin).
The body two ends of mandrel 24 are male threaded end 3 401 and male threaded end 4 402, this body diameter of mandrel 24
It is 41mm.The design size of mandrel 24 is Φ 41, covers two with two pieces crankshaft bearing and runs through bolt hole and be connected as gap and join
Close, the longest mandrel.The gap that long mandrel in use may be used to adjust two the bearing cap faying faces coupled together is big
Little, eliminate the problem of stress concentration of two binding faces simultaneously.
Mandrel 1 and mandrel 24 can limit two parts and collect together.
Then, the most clamping aforementioned crankshaft bearing cap 1 and crankshaft bearing cap 22 Grouped Jobs are contained in lathe work
On platform, with four groups of hold down gags respectively the two pieces crankshaft bearing cap part of the most clamping processed in batches and workbench are connected,
Being pressed together use, the processed in batches that thus can carry out crankshaft bearing cap weight inner bore of part (is got on the bus in part at vertical car
Hole dimension).Specifically, four set hold down gags include the first hold down gag, the second hold down gag, the 3rd hold down gag and the 4th pressure
Tight device.The structure of four set hold down gags is identical.First hold down gag include first T-nut the 10, first bolt 11,
One pressing plate 12 and the first band shoulder nut 13, the middle part of the first pressing plate 12 is provided with hole, and the floor installation of the first T-nut 10 is at lathe
On workbench 9, the first bolt 11 is connected through the hole on the first pressing plate 12 with the first T-nut 11, the first band shoulder nut 13 and
The upper end of the first bolt 11 is tightened, and the shoulder of the first band shoulder nut 13 pushes down the first pressing plate 12, and the first pressing plate 12 is pressed in Crankshaft
Hold on lid 1.
Second hold down gag is made up of the second T-nut, the second bolt, the second pressing plate and the second band shoulder nut.3rd pressure
Tight device is made up of the 3rd T-nut, the 3rd bolt, the 3rd pressing plate and the 3rd band shoulder nut.4th hold down gag is T-shaped by the 4th
Nut, the 4th bolt, the 4th pressing plate and the 4th band shoulder nut are constituted.
Second hold down gag, the 3rd hold down gag and the installation method of the 4th hold down gag and the first hold down gag are identical.
First hold down gag and the second hold down gag are used for compressing crankshaft bearing cap 1, and the second hold down gag is positioned at position, the lower right corner in Fig. 6
Put.3rd hold down gag and the 4th hold down gag are used for compressing crankshaft bearing cap 22, and the 3rd hold down gag is positioned at upper left in Fig. 6
Angle Position, the 4th hold down gag is positioned at position, the lower left corner in Fig. 6.
After the endoporus of this group crankshaft bearing cap part processes, first hold down gag that unclamps and back-out, the second compression dress
Put, four bands shoulder nuts on the 3rd hold down gag and the 4th hold down gag, thus disassemble respectively the first hold down gag, second
Hold down gag, the 3rd hold down gag and the 4th hold down gag, take off machined complete crankshaft bearing cap 1 and crankshaft bearing cap two
2, band of back-outing shoulder nut 1, band shoulder nut 26, band shoulder nut 37 and band shoulder nut 48, then take out mandrel 1 and core respectively
Axle 24, takes apart machined complete two pieces crankshaft bearing cap part, completes the whole endoporus course of processing.
So hole size of processing disclosure satisfy that product drawing requirement, it is ensured that this crankshaft bearing cap inner bore of part is processed
Quality, can improve endoporus working (machining) efficiency simultaneously, and recording workpoints at processed in batches frock mandrel 1 and mandrel 24 subscript fills numbering and institute
Processing part name, can effectively prevent the maloperation of workman.
Repeat said method and process next group crankshaft bearing cap inner bore of part size, to realize batch machining one-tenth product.
Owing to this special group working device is an assembly, endoporus processed in batches frock and crankshaft bearing cap part,
The combination of platen, hold down gag is used together, and uses centrage principle (plane and two pits), for avoiding in the course of processing
Repeat centering, adjust back and forth, extend the service life of special group working device.Endoporus processed in batches tool component is steel part,
Carry out modifier treatment (harden 40-45HRC), not only ensure that the endoporus crudy of crankshaft bearing cap part, can improve simultaneously
The service life of endoporus processed in batches frock.
The above, only to the preferred embodiments of the present invention, is not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.In the range of every claim in the present invention limits, done
Any modification, equivalent substitution and improvement etc., all should be within protection scope of the present invention.
