Abstract

The utility model provides an arm structure roof beam, it includes upper beam and underbeam, a serial communication port, upper beam and underbeam all include left side roof beam, right side roof beam and bridge, left side roof beam and right side roof beam structure are the same, pass through between the two the bridge is connected, the both ends of left side roof beam and right side roof beam are provided with the screw respectively. The arm structure beam increases the thickness and the width of the fixed point of the arm structure beam, so that the area between the fixed point of the manipulator and the contact surface of the machine body is increased when the manipulator moves up and down, the manipulator is not easy to shake when moving up and down, the stability of the manipulator is improved, and the service life of the manipulator is prolonged.

Description

Arm Structural Beam

technical field

The utility model belongs to the mechanical field, in particular to an arm structure beam used on a bridge-type manipulator.

Background technique

Referring to Fig. 1 and Fig. 2, the arm structure beam used on the existing bridge-type manipulator has relatively weak fixed parts at its four corners, so when the arm structure beam drives heavy objects to move up and down, its fixed position is easy to shake, which is easy to cause The shaking of the heavy objects it carries affects the working performance of the bridge manipulator, so it is of great significance to develop a new type of arm structure beam that is not easy to shake.

Utility model content

The technical problem to be solved by the utility model is: aiming at the structural defects of the existing arm structure beams, a new arm structure beam with high strength and stable structure is provided.

The technical solution adopted by the utility model for solving the problems of the technologies described above is:

A kind of arm structure beam, it comprises upper beam and lower beam, and described upper beam and lower beam all comprise left beam, right beam and bridge, and described left beam and right beam structure are identical, and the bridge is connected between the two Connection, the two ends of the left beam and the right beam are respectively provided with screw holes.

The left beam, the right beam and the bridge are all provided with a central hole.

The beneficial effects of the utility model are: the above-mentioned arm structure beam increases the thickness and width around its screw hole, so that when the manipulator moves up and down, the area between its fixed point and the contact surface of the body increases, so that it can It is not easy to shake when moving up and down, which increases its stability and prolongs its service life.

Detailed ways

Referring to Fig. 3, a kind of arm structure beam, it comprises upper beam 1 and lower beam 2, and upper beam 1 comprises left beam 4, right beam 5 and bridge 6, is connected by bridge 6 between left beam 4 and right beam 5, The left beam 4, the right beam 5 and the bridge 6 are all provided with a central hole, and the two ends of the left beam 4 and the center position of the bridge 6 are respectively provided with screw holes 3, the structure of the right beam 5 is the same as that of the left beam 4, and the screws are respectively Through each screw hole 3, the upper beam 1 is fixed on the bridge manipulator.

The lower beam 2 includes a left beam 7, a right beam 8 and a bridge 9, the left beam 7 and the right beam 8 are connected by the bridge 9, the lower beam 2 is provided with a central hole, and the central hole runs through the entire lower beam 2, and the left beam 7 and the two ends of the right beam 8 are respectively provided with screw holes 3, and the screws pass through each screw hole 3 respectively to fix the lower beam 2 on the bridge manipulator.

Both the upper beam 1 and the lower beam 2 are provided with screw holes 3, this structure effectively prevents the upper beam 1 and the lower beam 2 from shaking when they move up and down.

The central holes provided on the upper beam 1 and the lower beam 2 effectively reduce the weight of the arm structure beam, eliminate stress, and can bear greater weight.

The utility model is not limited to the above-mentioned embodiments, and all implementations that can achieve the purpose of the utility model are within the scope of the utility model.

Claims (2)

1. arm structure beam, it comprises puts the beams in place and underbeam, it is characterized in that, described upper beam and underbeam include Zuo Liang, right beam and bridge, described Zuo Liang is identical with right girder construction, is connected by described bridge between the two, and the two ends of described Zuo Liang and right beam are respectively arranged with screw.

2. arm structure beam according to claim 1 is characterized in that, is provided with centre bore on described Zuo Liang, right beam and the bridge.
