Further:

the end structure is a movable joint which is a movable sleeve, and the movable sleeve is hinged with the other end of the bolt thimble through a pin shaft.

A supporting arm is arranged on one side of the positioning frame body, a through hole aligned with the thimble hole is formed in the end portion of the supporting arm, and the bolt thimble penetrates through the through hole.

The supporting arm and the positioning frame body are of an integral structure.

The upper through hole and the two thimble holes of the supporting arm have the same parallelism.

The bolt thimble comprises a front section and a rear section, the rear section is connected with the end structure, the outer diameter of the front section is smaller than that of the rear section, and a thimble hole in the outer side is matched with the front section of the bolt thimble.

The outside of location support body corresponds to and is located outside thimble hole and is equipped with the notch.

Compared with the prior art, the utility model, have following advantage:

this be used for APM vehicle longeron tip support assembly device structural design is reasonable, through the position in definite hole when the tip support punches, improves the precision in hole, makes tip support both ends hole site keep the same position and depth of parallelism, and the effectual condition that prevents the unable equipment of longeron tip support takes place, has improved the efficiency of longeron tip support equipment greatly.

Detailed Description

The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.

As shown in fig. 1 to 5, the device for assembling the end bracket of the longitudinal beam of the APM vehicle comprises a positioning frame body 3 and a bolt thimble 1; the positioning frame body 3 is provided with a clamping groove used for being clamped on a support at the end part of the longitudinal beam 4 of the vehicle, two end parts of the clamping groove of the positioning frame body are provided with aligning thimble holes, one end of the bolt thimble is in threaded fit with one thimble hole, and the other end of the bolt thimble is provided with an end structure convenient to rotate.

Preferably, the end structure is movable joint 2, and movable joint 2 is the movable sleeve, and the other end of movable sleeve and bolt thimble is articulated continuous through the round pin axle, and the movable sleeve is the hexagon socket head cap sleeve, utilizes the instrument to insert and rotates and drive bolt thimble top tightly.

A supporting arm is arranged on one side of the positioning frame body 3, a through hole aligned with the thimble hole is formed in the end part of the supporting arm, and the bolt thimble penetrates through the through hole; furthermore, the upper through hole and the two thimble holes of the supporting arm have the same parallelism.

The supporting arm and the positioning frame body are of an integral structure; wholly be trapezoidal, middle fretwork, the top is fixed with the thimble hole of three the same depth of parallelism, is furnished with the bolt thimble, inserts the thimble hole when punching, and the thimble end is furnished with the movable joint for screw, rotatable direction atress of screwing.

The bolt thimble comprises a front section and a rear section, the rear section is connected with the end structure, the outer diameter of the front section is smaller than that of the rear section, and a thimble hole positioned on the outer side is matched with the front section of the bolt thimble; the outside of location support body corresponds to be located outside thimble hole and is equipped with the notch, simple and convenient tip support operation of punching.

The device positioning frame body is placed under the end support of the longitudinal beam in a handheld mode, and the ejector pin of the screw rod is inserted into the ejector pin hole until the ejector pin is aligned with the punching position of the end support of the longitudinal beam; the drilling can be performed according to the reserved hole point of the support, or the small drill bit is used for directly drilling, and then the large drill bit is used for reaming.
