Description

Technical Field

[0001] This utility model relates to the field of bolt tightening equipment technology, and in particular to a bolt tightening device for anti-torsion arm bolts. Background Technology

[0002] Commercial vehicle chassis assemblies have many components and complex assembly processes, with a particularly large number of bolt tightening operations. There are many very important connection points. At present, most production processes use pneumatic wrenches to tighten the bolts and then use torque wrenches to tighten them again to ensure the tightening torque and control the quality. Therefore, a special bolt tightening equipment is needed on the production line to tighten the bolts on the products.

[0003] For example, CN112571035A, published on March 30, 2021, discloses a tightening device and process method for automotive swing arm connecting bolts, belonging to the field of automotive equipment technology. This device includes a swing arm positioning workstation and a longitudinal swing arm tightening electric gun and an oblique swing arm tightening electric gun. The positioning workstation has a vertically movable lifting base, with a first base plate and a second base plate on the lifting base. The first base plate has a top plate, which can move on the lifting base to contact the end of the longitudinal swing arm of the vehicle frame. The second base plate has a clamping component for holding the oblique swing arm on the vehicle frame. Both the longitudinal and oblique swing arm tightening electric guns include a reaction arm, the end of which is rotatably connected to a rotating component. A fixed plate is connected to the rotating component, and a hammering fixture for tightening the connecting bolts on the swing arm is provided on the fixed plate. The aforementioned device cannot easily adjust the distance between the tightening electric gun and the hammering fixture, resulting in poor practicality. Summary of the Invention

[0004] The purpose of this invention is to provide a more practical anti-torsion bolt tightening device. This invention uses a guide mechanism to easily adjust the relative positions of the tightening electric guns and the anti-torsion brackets on both sides of the moving base, thereby achieving convenient bolt tightening and improving practicality.

The hammer-on locking seat is connected to the movable seat through a guide mechanism.

[0006] The guiding mechanism includes a guide post connected to the movable seat, a guide cylinder on the guide post, an adjusting seat on the guide cylinder, and the adjusting seat connected to the knocking seat.

[0007] The guide post passes through the movable seat. One end of the guide post is provided with an end cap and a pad. The other end of the guide post is provided with a mounting seat. The tightening electric gun is connected to the mounting seat. The mounting seat is provided with a rotating locking block connected to the tightening electric gun.

[0008] The guide post is provided in two parts, and each of the two guide posts is provided with two guide cylinders, which are connected to the adjustment seat.

[0009] The adjusting seat is provided with a first horizontal plate, and the first horizontal plate is provided with a first handle. The mounting seat is provided with a second horizontal plate, and the second horizontal plate is provided with a second handle.

[0010] The movable seat is also provided with a base, a vertical column on the base, a guide cylinder on the vertical column, a horizontal seat on the guide cylinder, the horizontal seat being connected to the movable seat, and a balancer connected to the horizontal seat on the vertical column.

[0011] A horizontal column is fitted onto the horizontal seat, and a side seat is provided on the horizontal column. The side seat is connected to the movable seat through a connecting column.

[0012] The horizontal seat is provided with a vertical plate, and the vertical plate is provided with a through hole for connecting to the balancer.

[0013] The beneficial effects of this utility model are:

[0014] The movable seat moves to the upper side of the workpiece, and the countersink is moved by the guide mechanism. The countersink fixes the bolt head, and the tightening electric gun tightens the nut. The guide mechanism allows for easy adjustment of the distance between the countersink and the tightening electric gun, making it easier for the bolt tightening device to tighten bolts of different lengths, thus improving its practicality.

[0015] The distance between the tapping seat and the tightening electric gun can be easily adjusted by the cooperation of the guide post, guide cylinder and adjusting seat, so as to facilitate the tightening of bolts of different lengths;

[0016] By coordinating the vertical column, guide cylinder, horizontal seat, and connecting column, the horizontal and vertical positions of the movable seat can be adjusted, making it easier to move the tightening electric gun to different positions for bolt tightening work, thus increasing its practicality.
