Positioning structure of steel pipe

Technical Field

The utility model belongs to the technical field of steel pipe processing, a location structure of steel pipe is related to.

Background

The cutting main body of the mower is a steel pipe, flanges are arranged at two ends of the steel pipe, an installing head is fixedly connected to the outer sides of the flanges, and a plurality of blades for mowing are fixedly connected to the outer wall of the mowing column. In the prior art, the blade is fixed on the mowing column in a welding mode, so that a steel pipe needs to be positioned in the blade welding process.

In the prior art, the positioning of the steel pipe is usually performed by two-end positioning, for example, chinese patent document discloses a steel pipe flange assembling insertion positioning device [ patent No.: 201711143687.4, respectively; application publication No.: CN107962339A ], including the supporting seat of two relative settings, all be equipped with the chuck that has the locating hole on two supporting seats, be equipped with three jack catchs that can support by the work piece on the chuck.

The positioning device can clamp the steel pipe of the mower. When the steel pipe is positioned, the steel pipe is firstly required to be placed, when the structure is placed, the distance between the two supporting seats is required to be adjusted by one person, and the other person supports the steel pipe and embeds the end part of the steel pipe into the positioning hole of the chuck. After the steel pipe was placed, by three jack catch positions on the manual regulation chuck again, make the jack catch support and lean on the steel pipe, fix a position the jack catch then to realize the location at steel pipe both ends. However, in order to realize the positioning of the steel pipe, the structure needs manual intervention on one hand, and on the other hand, the adjustment of the positioning device in the positioning process is complicated, so that the positioning efficiency of the steel pipe is low.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide a location structure of steel pipe, the technical problem of solution is the location efficiency who how to improve the steel pipe.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a location structure of steel pipe, includes the chuck, be equipped with the support frame on the chuck, its characterized in that, set up the constant head tank that the opening upwards just supplied the work piece embedding on the support frame, location structure still includes that the centre gripping clearance that is used for the centre gripping work piece is formed between setting element and the support frame, be equipped with on the support frame and link firmly the setting element and can drive the driving piece that the setting element removed.

The steel pipe of the existing mower can be positioned by the positioning structure of the steel pipe, and the steel pipe of the mower is provided with the flange and the mounting head, and the support frame is provided with the positioning groove which is provided with an upward opening and is used for embedding the workpiece, so the distance between the groove walls of the positioning groove can be set to be slightly larger than the diameter of the mounting head, and the steel pipe can be placed on the support frame from the opening of the positioning groove above the support frame by a manipulator. After the steel pipe is placed, the groove wall of the positioning groove has a limiting effect on the mounting head, so that the steel pipe can be conveniently positioned on the support frame in a follow-up manner, and the positioning efficiency of the steel pipe is improved. A clamping gap for clamping a workpiece is formed between the positioning piece and the support frame, namely whether the limiting plate is positioned between the positioning piece and the support frame is the key for positioning the steel pipe. Because of the driving piece can drive the setting element and remove, make the position of setting element controllable, if the steel pipe is not leaning on the support frame placing the back flange, remove by driving piece drive setting element this moment, the removal of setting element provides the space of stepping down for the axial displacement of flange, and then can make the flange can paste and lean on the support frame through promoting current steel pipe, pastes when the flange and leans on behind the support frame, the setting element of driving piece secondary drive removes, makes the flange be located between setting element and the support frame.

Because of revolving cylinder's output shaft and locating lever parallel arrangement, so revolving cylinder drives the locating lever rotatory, reduces the change in centre gripping clearance as far as to guarantee positioning stability.

In the above positioning structure for the steel tube, the positioning rod is further screwed with a nut, the nut is located between the follower block and the positioning head, and the nut can be attached to the positioning head. Because of the nut spiro union is on the locating lever, and the nut can paste and lean on the locating head, makes the nut play spacing left and right sides to the locating head, guarantees positioning stability.

In the location structure of foretell steel pipe, the constant head tank runs through the inboard of backup pad, the support frame is still including the base of connecting the chuck, the base links firmly with the backup pad and is formed with the space of stepping down that supplies the manipulator embedding between the inboard of base and backup pad. Because of the inboard that the backup pad was run through to the constant head tank, the manipulator can imbed the space of stepping down of intercommunication constant head tank, makes the manipulator can assist steel pipe embedding constant head tank, and steadily places the steel pipe of centre gripping in the constant head tank, avoids the adjustment after the steel pipe is placed, improves positioning efficiency from this.

In the above positioning structure for the steel pipe, the number of the positioning members is two, and the positioning groove is located between the two positioning members. The arrangement positions of the two positioning parts further ensure that the steel pipe is firmly positioned between the supporting plate and the positioning parts.

In the above positioning structure of the steel pipe, the positioning groove is U-shaped. The U-shaped positioning groove enables the steel pipe to be conveniently embedded, the placing speed of the steel pipe is improved, and therefore the positioning efficiency is improved.

Compared with the prior art, the utility model provides a pair of location structure of steel pipe has following advantage:

1. on the support frame that can place the steel pipe through the decline of manipulator, rethread revolving cylinder drive setting element rotates and can fix a position the flange of steel pipe tip, avoided artificial intervention among the positioning process to the steel pipe, and the location step is few, improves the location efficiency of steel pipe from this.

2. In the process of placing the steel pipe on the support frame, the manipulator is embedded into the abdicating space, so that the embedding of the steel pipe is guided, the placing speed of the steel pipe is further improved, and the positioning efficiency of the steel pipe is further improved.
