Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of pipe positioning and processing in the continuous conveying process of straight-seam welded pipe production lines, and particularly relates to an offline adjustable positioning device facilitating pipe positioning and processing. BACKGROUND
[0002] After the pipe is cut to size in the welded pipe production line, deburring or threading operations are usually required on the two ends of the pipe. The basic prerequisite for the above operations is to first accurately fix the pipe so that the pipe is accurately within the processing range of the processing equipment. However, the pipe is usually continuously conveyed on the conveyor belt or the conveying roller way of the production line, and its position is real-time changing. Therefore, the pipe in the continuous conveying process cannot be subjected to deburring or threading operations on the two ends of the pipe. Therefore, it is an inevitable trend for those skilled in the art to develop an offline adjustable positioning device that can fix the pipe away from the conveyor belt or the conveying roller way. SUMMARY
[0003] The present embodiment provides an offline adjustable positioning device that can fix the pipe in the continuous conveying process away from the conveyor belt or the conveying roller way. The technical solution has the advantages of simple structure, easy maintenance and repair, wide application range, cost saving, and improved precision and efficiency.

The device is provided with a conveying device s, on which the bar b is conveyed side by side, and an offline lifting device t. The offline lifting device t is further provided with a lifting clamp q. A downwardly recessed positioning groove c is arranged on the lifting clamp q. A lifting telescopic cylinder ss is arranged below the lifting clamp q. The conveying device s and the lifting telescopic cylinder ss are arranged on a base d. The lifting telescopic cylinder ss is arranged below the conveying device s. The lifting telescopic cylinder ss can drive the lifting clamp q to move from below the conveying device s to above the conveying device s and grasp the bar b through the lifting clamp q, so that the bar b is separated from the conveying device s and slides into the positioning groove c to achieve accurate positioning.
[0005] According to one aspect of the embodiment of the present application, the positioning groove c is arranged at the central part of the upper end surface of the lifting clamp q, and the positioning groove c is in a V shape.
[0006] According to one aspect of the embodiment of the present application, a limiting stop k is further arranged on the base d at the opposite side of the lifting clamp q above the conveying device s. The lifting clamp q can lift the bar b to stop and position at the limiting stop k.
[0007] According to one aspect of the embodiment of the present application, the limit block k is further provided with a limit positioning groove xc on the side facing the lifting tongs q, which can cooperate with the positioning groove c to realize accurate positioning of the bar b.

[0019] As Figure 1As shown, the present embodiment provides an offline adjustable positioning device that can separate the pipe fittings in the continuous conveying process from the conveying belt or conveying roller and then be fixed. The technical solution has the advantages of simple structure, easy maintenance, wide application range, cost saving, and improved precision and efficiency. In the specific embodiment, a conventional belt or chain conveying device s can be provided, and the round or square bars b are conveyed side by side on the conveying device s. The conveying device s is arranged on a base d placed on the ground, and in the present embodiment, the conveying surface of the conveying device s is preferably arranged horizontally. An offline lifting device t capable of achieving a lifting positioning action is arranged on the base d at a position passed by the conveying surface of the conveying device s. The offline lifting device t is further provided with a lifting clamp q arranged in a vertical direction, and the lifting clamp q is capable of moving in an upward and downward direction.
[0020] In the present embodiment, a downwardly recessed positioning groove c is arranged on the lifting clamp q, and the downwardly recessed positioning groove c is preferably in a V shape, and the V-shaped positioning groove c is arranged at the center of the upper end surface of the lifting clamp q. A lifting telescopic cylinder ss capable of achieving a telescopic action is further arranged below the lifting clamp q, and in the present embodiment, the lifting telescopic cylinder ss is preferably a telescopic pneumatic cylinder. The conveying device s and the lifting telescopic cylinder ss are both arranged on the base d, and the lifting telescopic cylinder ss is arranged below the conveying device s. The lifting telescopic cylinder ss is capable of driving the lifting clamp q to move from below the conveying device s to above the conveying device s, and the lifting clamp q is capable of grabbing the bar b to make the bar b separate from the conveying device s and slide into the positioning groove c to achieve precise positioning.
[0021] According to an aspect of the specific embodiment of the present application, a limiting block k capable of adjusting the height position is further arranged on the base d at the opposite side of the lifting clamp q above the conveying device s. When the lifting telescopic cylinder ss generates an extension action, the lifting clamp q is capable of lifting the bar b to stop and position at the limiting block k.
[0022] Preferably, a limiting positioning groove xc is further arranged on the side of the limiting block k facing the lifting clamp q, and the limiting positioning groove xc is capable of cooperating with the positioning groove c to achieve precise positioning of the bar b.

[0026] As Figure 1 and Figure 2 shown, when the present technical solution needs to work, first, the conveying device s conveys the bar b to the position below the work station which needs to deburr the two ends of the pipe or thread the two ends of the pipe, then the lifting telescopic cylinder ss generates the extension action, the lifting clamp q is lifted upward under the action of the extension action of the lifting telescopic cylinder ss to make the positioning groove c pick up the bar b, and then continuously lift until the lifting clamp q pushes the bar b into the limiting positioning groove xc, so that the bar b is completely positioned under the mutual action of the limiting positioning groove xc and the positioning groove c. After processing is completed, the lifting telescopic cylinder ss generates the retraction action, the lifting clamp q drives the bar b to fall back onto the conveying device s, and synchronously, the lifting clamp q falls below the conveying surface of the conveying device s, and the operation is completed.
