And,, therefore can carry out the assembling of chain 1 easily because the manufacturing installation S of the chain 1 that present embodiment relates to can carry out the assembling of chain 1 by said method.

And, in the present embodiment, though utilize anchor clamps 6 to keep two groups of chain pin parts P, and be pressed into link plate 2 piecewise, but also can keep more a plurality of even whole chain pin parts P simultaneously, and the link plate 2 that is disposed at same row in the chain 1 once is pressed into the whole of multi-disc or length direction, and assemble.

And,, also can form grooving portion the both sides of clamping plate 8 and pressing plate 9 though in the anchor clamps 6 of present embodiment, only on clamping plate 8, be formed with the grooving portion consistent with the outer peripheral face shape of chain pin 3 and fillet 4.

Below, the manufacturing installation of the above-mentioned chain 1 that second embodiment of the present invention is related to is elaborated.Fig. 4 is the ideograph of the manufacture method of the manufacturing installation of expression chain 1 and the chain 1 that has adopted this device.

Shown in Fig. 4 (a), the manufacturing installation S of the chain 1 of present embodiment comprises: assembly jig 15, and it is used to keep outer peripheral face 3a, the 4a of a plurality of chain pins 3 and fillet 4; Patrix 16, it is configured in the top of assembly jig 15, and by together dropping to the below with link plate 2, and above-mentioned maintained chain pin 3 and fillet 4 are pressed into the pin-and-hole 2a of link plate 2.

Assembly jig 15 comprises: rectangular-shaped assembly jig main body 17, and it is formed with a plurality of locating hole 17a, and this locating hole is by insertion and take in chain pin 3 and fillet 4, and keeps its outer

peripheral face

3a, 4a; Retainer 18, it has a plurality of latch 18a that are inserted into this locating hole 17a.

Assembly jig main body 17 for example is the metal die that is formed by carbon tool steel and alloy tool steel etc., and it is vertical with respect to upper surface 17b to form above-mentioned locating hole 17a, and is communicated with upper surface 17b and lower surface 17c.

Locating hole 17a, so that the locating hole 17a of its adjacency each other gap width and the gap width of chain 1 have identical distance, and keep being adapted to row as the chain pin 3 of the required radical of chain 1 and the mode of fillet 4 along the length direction of assembly jig 15.The inner peripheral surface shape of this locating hole 17a forms: the shape that formed outer peripheral face shape is consistent when being assembled into chain 1 with 4 combinations of the chain pin 3 that is inserted and fillet, and the inner peripheral surface shape of the pin-and-hole 2a of the link plate 2 of its shape when being configured to chain 1 is consistent.By such setting, can be to chain pin 3 and the fillet 4 that is inserted into locating hole 17a, the mode with the pin-and-hole 2a that is pressed into link plate 2 positions.And, the clearance of the locating hole 17a when inserting chain pin 3 and fillet 4, the degree of the play that is configured to successfully to plug and not rock etc.

Wherein be inserted with above-mentioned latch 18a from the following direction of each locating hole 17a.Latch 18a adopts carbon tool steel and alloy tool steel to wait and forms, and one is based on the retainer 18 of the below that is configured in assembly jig main body 17.The front end of this latch 18a be inserted into the chain pin 3 of locating hole 17a and the lower side front end butt of fillet 4, and the position of the above-below direction of chain pin in the locating hole 17a 3 and fillet 4 is positioned.

And retainer 18 constitutes: together be installed in the not shown forcing press etc. with assembly jig main body 17 and patrix 16, and make it move, and can fix along the vertical direction can be with respect to assembly jig main body 17 keeping parallelisms the time.Thus, latch 18a is moved along the vertical direction to be inserted into respectively under the state in the locating hole 17a, and fix.Thus, can chain pin 3 and the fillet 4 of locating hole 17a will be inserted into, be fixed in along on the optional position of the above-below direction in the locating hole 17a, and to have the mode of protuberance T described later, the relative assembly jig main body 17 of latch 18a (retainer 18) is fixed, wherein, this protuberance T makes as the upper end of an end of chain pin 3 and fillet 4 height dimension from the outstanding regulation of upper surface 17b and forms.

Like this, latch 18a (retainer 18) is constructed as follows the outstanding unit of chain pin parts, and this unit makes the upper end of chain pin 3 and fillet 4 outstanding from upper surface 17b with not shown forcing press.

And the front end of latch 18a is lower than the mode of fillet 4 lower ends slightly with the lower end of chain pin 3, is provided with jump.Thus, can in the following manner chain pin 3 and fillet 4 be positioned to axial, that is: when chain pin 3 and fillet 4 butts, chain pin 3 that its axial length dimension there are differences and the axial location between the fillet 4 concern, and be identical when becoming chain 1 with assembling.

This assembly jig 15 is constructed as follows anchor clamps with not shown forcing press, and these anchor clamps keep outer

peripheral face

3a, 4a by a plurality of chain pins 3 and fillet 4 are accommodated in the locating hole 17a, and the state when becoming chain 1 with assembling is arranged.

Patrix 16 adopts carbon tool steels and alloy tool steel etc. and forms rectangular-shapedly, by making its lower surface 16a and link plate 2 butts, and below dropping to, chain pin 3 and fillet 4 can be pressed into the pin-and-hole 2a of link plate 2 and laminated configuration link plate 2.And,, to dodge in order making, and in patrix 16, to be formed with a plurality of through hole 16b that can insert logical chain pin 3 and fillet 4 from pin-and-hole 2a outstanding chain pin 3 and fillet 4 when being pressed into link plate 2 this patrix 16 is descended.

And as implied above, patrix 16 is installed in not shown forcing press etc. with assembly jig main body 17 and retainer 18.And these metal dies can pass through the operating pressure machine, and are maintained at state parallel to each other mutually, but and when in stroke range along the vertical direction, coming and going shifting movement respectively, and can be fixed in position arbitrarily in the above range.

This patrix 16 is constructed as follows the link plate dispensing unit with not shown forcing press, and the link plate 2 that this unit is used for being pressed into chain pin 3 and fillet 4 slides along chain pin 3 and fillet 4, and is disposed at the assigned position on chain 1 width.

Shown in Fig. 4 (a), be assembling chain 1, at first chain pin 3 and fillet 4 are inserted and be accommodated in the locating hole 17a of assembly jig main body 17, and arrange as the required radical of chain 1.Thus, when chain pin 3 and fillet 4 utilized locating hole 17a to keep its outer

peripheral face

3a, 4a, the state when becoming chain 1 with assembling was arranged.

So, in upper end with chain pin 3 and fillet 4 mode from the outstanding protuberance T of upper surface 17b, with latch 18a (retainer 18) relatively assembly jig 15 fix.Here, the outstanding following length dimension of protuberance T is fixed, this length dimension is as the part among the whole columns of regulation columns i.e. a row link plate 2 and required length dimension in configuration on the width of chain 1.

If necessary, then also the projecting height size of this protuberance T can be made as the size of configurable multiple row.But be preferably the projecting height size of protuberance T as far as possible little (disposing the required length dimension of a row link plate).Its reason be because, if the projecting height size is less, then chain pin 3 and fillet 4 are inserted into the length dimension increase in the locating hole 17a, and therefore the hold in range by assembly jig 15 couples of outer

peripheral face

3a, 4a increases, and can keep chain pin 3 and fillet 4 more reliably.

Secondly,, come a row link plate 2 is kept, and make the lower surface 16a butt of itself and patrix 16 by (not shown) such as anchor clamps that the upper end that makes pin-and-hole 2a and chain pin 3 and fillet 4 as one man keeps them, and the patrix 16 that slowly descends.Thereby, the pin-and-hole 2a that makes the chain pin 3 that keeps by assembly jig 15 and fillet 4 be pressed into above-mentioned link plate 2 from the upper end side.And, shown in Fig. 4 (b), this link plate that is pressed into 2 is slided along chain pin 3 and fillet 4, and is disposed at the position with the upper surface 17b butt of assembly jig main body 17.Thus, these link plates 2 are configured in protuberance T.

And, here, though by maintenance link plates 2 such as anchor clamps, and make pin-and-hole 2a consistent with the upper end of chain pin 3 and fillet 4, and be pressed into link plate 2 by patrix 16, but also can be before utilizing patrix 16 to be pressed into, chain pin 3 and fillet 4 are pressed into pin-and-hole 2a etc. lightly, upper end that link plate 2 is pressed into or is inserted into chain pin 3 and fillet 4 in advance etc. is carried out temporary fixed, keeps thus, and makes pin-and-hole 2a consistent with the upper end of chain pin 3 and fillet 4.

Secondly, shown in Fig. 4 (c), only latch 18a (retainer 18) is improved upward, and make the upper end side of chain pin 3 and fillet 4 outstanding with respect to upper surface 17b, thereby can be between the link plate 2 and upper surface 17b of above-mentioned configuration, the gap U of the gauge same degree of an acquisition and a row link plate 2.And, shown in Fig. 4 (d), further press mould 16 downwards from the state of (c), link plate 2 is slided along chain pin 3 and fillet 4, and be disposed at the position with the upper surface 17b butt of assembly jig main body 17.

So shown in Fig. 4 (e), if patrix 16 is promoted upward, the upper end that then can form chain pin 3 and fillet 4 is from the outstanding protuberance T ' of the pin-and-hole 2a of link plate 2.At this moment, protuberance T ' gives prominence to following length dimension, promptly disposes the required length dimension of a row link plate 2 along the width of chain 1.

Secondly, shown in Fig. 4 (f), laminated configuration one row link plate 2 again on protuberance T '.So, adopt patrix 16, assembly jig 15 and counterdie to form protuberance T ', and repeat it is disposed the above-mentioned operation of a row link plate 2, and arrangement according to the rules, length direction and width along chain 1 stack gradually configuration link plate 2, and are assembled into chain 1.

And, in the present embodiment, though can be on protuberance T, T ' laminated configuration one row link plate 2, when the projecting height size with protuberance T, T ' is made as the size of configurable multi-disc, also can once dispose multiple row.

As mentioned above, chain 1 is disposed at link plate 2 on the chain pin parts P that is arranged in row by utilizing assembly jig 15, and can be assembled into a chain 1 that the joint shape is arranged.So,, can obtain the chain 1 of ring-type by connecting the two ends of this chain that the joint shape is arranged 1 that is assembled into.

The manufacture method of the chain 1 that relates to according to aforesaid present embodiment, the a plurality of chain pins 3 that state in the time of will becoming chain 1 with assembling is arranged and outer peripheral face 3a, the 4a of fillet 4, keep by assembly jig 15, can position chain pin 3 and fillet 4 exactly thus.Thereby, can reliably chain pin 3 and fillet 4 be pressed into the pin-and-hole 2a of link plate 2, and can easily carry out the assembling of chain 1.

And shown in Fig. 4 (g), when stacking gradually configuration during link plate 2, chain pin 3 and fillet 4 increase from the overhang of assembly jig 15, and therefore the scope of outer peripheral face 3a, the 4a of chain pin 3 that is kept by assembly jig 15 and fillet 4 reduces.On the other hand, because the pin-and-hole 2a by the link plate 2 of laminated configuration on upper surface 17b keeps outer peripheral face 3a, the 4a of chain pin 3 and fillet 4, so can keep the state that chain pin 3 and fillet 4 are accurately located.

And the manufacturing installation S of the chain 1 that present embodiment relates to can assemble chain 1 by said method, therefore can easily carry out the assembling of chain 1.

Below, with reference to Fig. 5, other manufacture method of the manufacturing installation S that adopted above-mentioned second embodiment is described.In manufacture method shown in Figure 4, dispose link plate 2 from an end of chain pin by row, in contrast to this, the difference of manufacture method shown in Figure 5 is, initial is earlier that three row link plates are disposed on the assigned position of assembling when becoming chain 1 with the part among the whole columns, thereafter, with the part among the whole columns promptly a row link plate be disposed at successively on the assigned position when being assembled into chain 1.

Shown in Fig. 5 (a), at first chain pin 3 and fillet 4 inserted and be accommodated in the locating hole 17a of assembly jig 15, and the state when becoming chain 1 with assembling is arranged to it and is kept.And this moment, as shown in the figure,, they are kept to have the mode that makes as the outstanding protuberance T in the upper end of an end of chain pin 3 and fillet 4.Here, the outstanding width along chain 1 of this protuberance T disposes three row link plates 2 and required length dimension.

Secondly, the upper end by making pin-and-hole 2a and chain pin 3 and fillet 4 with predetermined arrangement keeps three link plates 2 that are listed as one man to its (not shown) such as anchor clamps that keeps, and makes the lower surface 16a butt of itself and patrix 16, and the patrix 16 that slowly descends.Thereby, the pin-and-hole 2a that makes the chain pin 3 that keeps by assembly jig 15 and fillet 4 be pressed into above-mentioned link plate 2 from the upper end side.And, shown in Fig. 5 (b), the above-mentioned link plate that is pressed into 2 is configured along the position that chain pin 3 and fillet 4 slide into the most following link plate 2 and the upper surface 17b butt of assembly jig 15.Thus, these link plates 2 are configured in protuberance T.

Secondly, shown in Fig. 5 (c), only assembly jig main body 17 is dropped to the below and fix.At this moment, decline is assembled die main body 17 and is fixed in the following manner, that is: the bottom of chain pin 3 and fillet 4 is inserted into the length dimension of locating hole 17a, and the length dimension of giving prominence to from the outermost link plate 2 that is disposed at chain 1 with chain pin 3 and fillet 4 equates.

By such setting,, then this link plate 2 can be disposed at the most external of the assigned position of assembling when becoming chain 1 if link plate 2 is disposed at position with the upper surface 17b butt of assembly jig 15.That is the datum level when, upper surface 17b can be used as configuration link plate 2.And this moment is because the bottom of chain pin 3 and fillet 4 is inserted into locating hole 17a, so can continue to keep the maintenance of 15 pairs of chain pins 3 of assembly jig and fillet 4.

Secondly, shown in Fig. 5 (d), from the state of (c) patrix 16 is descended, and the most following link plate 2 is slided along chain pin 3 and fillet 4, and be disposed on the position with the upper surface 17b butt of assembly jig 15.At this moment, as mentioned above, the most following link plate 2 becomes and is configured in the assigned position of assembling when becoming chain 1, the outermost link plate 2 of width of chain 1, and as benchmark, the link plate 2 of other row also is configured in the assigned position on chain 1 width.

Secondly, shown in Fig. 5 (e), patrix 16 is promoted upward.So, stress newly to be pressed into a row link plate 2 from the upper end of chain pin 3 and fillet 4, shown in Fig. 5 (f), the link plate 2 that is pressed into is again slided along chain pin 3 and fillet 4, and be disposed at the assigned position on assigned position chain 1 width of assembling when becoming chain 1.After, by repeating above-mentioned operation, and arrangement according to the rules stacks gradually configuration link plate 2, and is assembled into chain 1.

As mentioned above, utilize assembly jig 15 that link plate 2 is disposed on the box member P that is arranged in row, be assembled into the chain 1 of joint shape thus.Then, by connecting the two ends of the chain that the joint shape is arranged 1 after this assembling, and can obtain the chain 1 of ring-type.

Manufacture method according to chain shown in Figure 51, when utilizing assembly jig 15 to keep outer peripheral face 3a, the 4a of chain pin 3 and fillet 4, also in the pin-and-hole 2a of three row link plates 2 of assigned position outer peripheral face 3a, the 4a of chain pin 3 and fillet 4 are kept, therefore can carry out accurate in locating chain pin 3 and fillet 4 by initial configuration.Thereby, even in the link plate 2 of configuration thereafter, also chain pin 3 and fillet 4 can be pressed among this pin-and-hole 2a reliably, and can easily carry out the assembling of chain 1.

And, in initial configuration after the three row link plates 2, link plate 2 can be disposed at assigned position by row ground, therefore can suitably adjust along chain 1 width in abutting connection with link plate 2 pressure of contact surface each other that disposes.Thus, can prevent that above-mentioned link plate 2 pressure of contact surface each other is too high and situation that frictional force is increased, the moment of flexure that therefore can suppress the chain 1 that caused by between the two frictional force increases, and prevents that the power transfer efficiency of this chain 1 from reducing.

And in Fig. 5 (b), the link plate 2 that is disposed at protuberance T is three row, but if necessary, the link plate 2 of also configurable more multiple row number perhaps is made as columns still less.

Most preferably be, these link plates 2 are configured to two row to four row.Its reason is, the columns of initial configuration is during more than this columns, owing to be pressed into the link plate 2 of this more columns simultaneously, so these link plates 2 pressure of contact surface each other increases, and might cause reducing as the power transfer efficiency of chain 1.And, if the columns of initial configuration less than this columns, then after having disposed these, is narrowed down to the outer peripheral face 3a of chain pin 3 and fillet 4, the hold in range of 4a by the pin-and-hole 2a of assembly jig 15 and link plate 2, thereby worries and can not keep it reliably.Be made as two row to four row by link plate 2, the hold in range of outer peripheral face 3a, the 4a of chain pin 3 and fillet 4 can be maintained effective size often initial configuration.Therefore, can position chain pin 3 and fillet 4 more reliably.

And, shown in Fig. 5 (c), if for the three row link plates 2 of initial configuration in protuberance T are configured on the assigned position, and being dropped to the below, fix assembly jig main body 17 relative retainers 18, then till finishing assembling, will assembly jig main body 17 not promote upward as chain 1.Thus, also this assembly jig main body 17 can be made as the structure that can cut apart along the vertical direction, promptly after three initial row link plates 2 are disposed at protuberance T, unload the assembly jig that is positioned at the below.

An example of the manufacture method of the chain 1 of Fig. 6 when to be expression with the assembly jig main body 17 of Fig. 4 and manufacturing installation S shown in Figure 5 be made as segmenting structure.In Fig. 6 (a), the assembly jig main body 17 of manufacturing installation S is made of patrix 19 and counterdie 20, and may be partitioned into two parts, connects to form locating hole 17a in this patrix 19 and counterdie 20.About other formation, since identical with Fig. 4 and content shown in Figure 5, so omit explanation.

When having adopted this assembly jig main body 17, can adopt the manufacture method of chain as follows 1.That is, shown in Fig. 6 (a), three row link plates 2 are disposed at protuberance T after, shown in Fig. 6 (b), assembly jig main body 17 is descended downwards, extract counterdie 20 simultaneously.
