Description

Alignment and positioning device for bridge box-shaped rods

technical field

The utility model relates to a fixture for manufacturing bridge box-shaped rods, in particular to an alignment and positioning device for bridge box-shaped rods.

Background technique

In the drilling process of bridge box-shaped rods, in engineering practice, the workpiece is often too long and the size of the box mouth is too large to be quickly aligned and accurately positioned, resulting in low precision of the hole group after the actual machining is completed.

Contents of the invention

The purpose of the utility model is to aim at the deficiencies in the prior art, and provide a bridge box-shaped bar alignment and positioning device that can quickly locate the bridge box-shaped bar and improve the machining accuracy of the hole group.

In order to achieve the above-mentioned purpose, the technical solution adopted by the alignment and positioning device of the bridge box-shaped bar of the utility model is:

A device for aligning and positioning bridge box-shaped rods, including a platform, at least two groups of vertical telescopic push rods are arranged on the lower part of the platform, and each group of vertical telescopic push rods includes two telescopic push rods. The upper side of the upper side is provided with at least two groups of horizontal telescopic push rods for clamping rods, and each group of horizontal telescopic push rods includes two horizontally opposite telescopic push rods.

The vertical telescopic push rod is a hydraulic push rod.

Each group of horizontal telescopic push rods includes a hydraulic push rod and an electric push rod.

The hydraulic push rods of each group of horizontal telescopic push rods are arranged on the same side.

Compared with the prior art, the utility model has the following advantages:

The bridge box-shaped rod is placed on the platform, the vertical telescopic push rod is used to adjust the level of the bridge box-shaped rod, and the horizontal telescopic push rod is used to adjust the horizontal position of the bridge box-shaped rod. After adjustment, the bridge box-shaped rod is fixed to realize It improves the rapid positioning and fixing of the workpiece, cooperates with the drilling machine to drill holes, and improves the processing accuracy of the hole group. The alignment and positioning device for bridge box-shaped rods of the utility model is simple and compact in structure, economical and practical, and reliable in structure.

detailed description

Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model, it should be understood that these embodiments are only used to illustrate the utility model and are not intended to limit the scope of the utility model, after reading the utility model, those skilled in the art will understand this utility model The modifications of various equivalent forms of the utility model all fall within the scope defined by the appended claims of the present application.

As shown in Figure 1, a bridge box-shaped bar alignment and positioning device includes a platform 1 for placing bridge box-shaped bars, and four vertical upward hydraulic push rods 2 are installed on the lower side of the platform 1. The push rods are installed side by side in pairs, and the hydraulic push rod 2 is used to adjust the level of the bridge box member. Two groups of horizontal telescopic push rods are installed on the upper side of the platform, each group of horizontal telescopic push rods includes a hydraulic push rod 3 and an electric push rod 4, and the hydraulic push rods and electric push rods of each group are arranged horizontally opposite each other. The hydraulic push rods 3 are arranged on the same side, and the electric push rods 4 of each group are arranged on the other side.

As shown in Figure 1, the bridge box-shaped rod 10 is placed on the platform 1, and the extension length of the vertically upward hydraulic push rod 2 is adjusted to adjust the bridge box-shaped rod 10 to be in a horizontal position, and the horizontal electric push rod is adjusted. The rod 4 is used to limit the position of the bridge box-shaped rod 10 in the horizontal direction, and the hydraulic push rod 3 locks and positions the bridge box-shaped rod 10 . The alignment and positioning device of the bridge box-shaped bar of the utility model is used in conjunction with a drilling machine, which improves the processing accuracy of the hole groups on the bridge box-shaped bar.
