But in the practical production application process, the diameter of work piece often is less, and like this for the transfer chain, under the prerequisite that satisfies fixed stock volume, need keep great pitch to match mechanical tongs between the V type frock tray on the transfer chain, but the less part of diameter is all stored to the tray of the most all condition, and the frock tray storage on the transfer chain is too sparse, will occupy the transfer chain length, increases the on-the-spot area of transfer chain.

Disclosure of Invention

The utility model discloses the technical problem that will solve lies in: the utility model provides a deep-hole drilling machine transfer chain of convertible pitch, it has solved among the prior art deep-hole drilling machine transfer chain because the frock tray can not transform the pitch and occupy the transfer chain length, increases the on-the-spot area's of transfer chain problem.

The utility model discloses the technical problem that will solve takes following technical scheme to realize:

a variable-pitch deep hole drilling machine conveying line comprises rail supports, chains and V-shaped tooling trays, wherein double rows of chains are arranged between the rail supports, each V-shaped tooling tray comprises a supporting plate, guide rollers and a chain wheel, the guide rollers are fixed on two sides below the supporting plate, a pair of chain wheels are fixed between the guide rollers on two sides below the supporting plate, the chain wheels drive by virtue of the chains, the guide rollers run along the rail supports, and the V-shaped tooling trays advance on the double rows of chains in a stepping mode;

the lifting support and the lifting cylinders form a lifting mechanism, the lifting mechanisms are sequentially obliquely fixed below the track support at different angles, when all the lifting cylinders are completely contracted, the lifting support is located under the corresponding V-shaped tooling pallet, and after all the lifting cylinders are completely extended, the lifting support lifts the corresponding V-shaped tooling pallets to the same height and increases the distance between the V-shaped tooling pallets.

As a preferable example, the lifting mechanism consisting of the lifting bracket and the lifting cylinder has 4, and 4 adjacent V-shaped tooling trays can be lifted and lowered at a time and the distance between the V-shaped tooling trays and the lifting mechanism is increased.

The utility model has the advantages that: a plurality of lifting mechanisms are obliquely fixed below the track support, each lifting mechanism consists of a lifting support and a lifting cylinder, the lifting cylinders extend to enable the lifting supports to support the V-shaped tooling trays, the distance between the supported V-shaped tooling trays is increased, the gripper distance of a mechanical gripper is reached, and the problems that the length of a conveying line is occupied due to the fact that the pitch of the V-shaped tooling trays cannot be changed, and the site floor area of the conveying line is increased are solved.

Detailed Description

In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.

As shown in fig. 1-6, a variable pitch deep hole drilling machine conveyor line comprises rail brackets 1, chains 2, and V-shaped tooling trays 3, wherein double rows of chains 2 are arranged between the rail brackets 1, each V-shaped tooling tray 3 comprises a supporting plate 31, a guide roller 32 and a chain wheel 33, the guide rollers 32 are fixed on two sides below the supporting plate 31, a pair of chain wheels 33 are fixed between the guide rollers 31 on two sides below the supporting plate 31, the chain wheels 33 are driven by the chains 2, the guide rollers 32 run along the rail brackets 1, and the V-shaped tooling trays 3 advance stepwise on the double rows of chains 2;

lifting support 4 and lift cylinder 5 constitute hoist mechanism, and a plurality of hoist mechanism incline in proper order with different angles and fix in track support 1 below, and when all lift cylinders 5 contract completely, lifting support 4 is located corresponding V type frock tray 3 under, and after all lift cylinders 5 extended completely, lifting support 4 promoted corresponding a plurality of V type frock tray 3 to the same height and increase interval each other.

The lifting mechanism consisting of the lifting support 4 and the lifting cylinder 5 is 4, and 4 adjacent V-shaped tooling trays 3 can be lifted and increased in distance each time.

The working principle is as follows:

as shown in fig. 1-6, a lifting cylinder 5 and a lifting support 4 form a lifting mechanism, 4 lifting mechanisms lift V-shaped tooling pallets 3, before the V-shaped tooling pallets 3 are lifted by the lifting mechanism, the V-shaped tooling pallets 3 on the chain 2 conveying line between the rail supports 1 are grouped into 4 and run in a stepping mode, the chain wheels 33 of the V-shaped tooling pallets 3 are driven by the chain 2 while the guide rollers 32 run along the rail supports 1, and the pitch between the 4V-shaped tooling pallets 3 is kept compact and proper.

One side of the double-row chain 2 which is stepped is provided with 4 lifting mechanisms, two sides of the V-shaped tooling pallet 3 are fixed with guide rollers 32, when every 4V-shaped tooling trays 3 in a group are stepped to the upper part of the corresponding lifting mechanism, the lifting cylinder 4 extends to drive the lifting bracket 4 to jack the V-shaped tooling trays 3 along the direction of a fixed angle, after the V-shaped tooling trays 3 are lifted by the lifting bracket 4, the chain wheel 33 is separated from the chain 2, the guide roller 32 is separated from the track bracket 1, the pitch between the group of 4V-shaped tooling pallets 3 which are jacked up is increased compared with the un-jacked V-shaped tooling pallet 2, and the pitch after the increase can be for the tongs distance phase-match of mechanical tongs 7, the utility model discloses both guaranteed deep-hole drilling machine work piece 6 by normally snatching, can solve again because of the problem of the extravagant transfer line length of occuping that the pitch arouses excessively between the V type frock tray 3 on the transfer line.
