Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, fig. 1 to 3 show an embodiment of the present invention, which is an improvement on a conventional rolling gun for mounting a skylight sealing strip in automobile manufacturing, and includes a gun body (not shown) and a gun head, wherein a motor in the gun body drives a belt pulley 5 on the gun head to rotate horizontally; the device also comprises a fixed roller mechanism and a movable roller mechanism; two movable rollers 2 and one fixed roller 1 face to the same side, and the direction is taken as the front direction in the embodiment.

Referring to fig. 3, the fixed roller mechanism includes a fixed roller 1, a flat fixed base 13, and a bracket 8, and the fixed roller 1 is connected to the fixed base 13 through the bracket 8.

The movable roller mechanism comprises two parallel movable rollers 2 and a flat plate 6, the movable rollers 1 are connected to a fixed base at the front end of the flat plate 6, and the lower surface of the flat plate 6 is placed into a concave guide rail (not shown) of a fixed base 13 through a slide block 14 so as to realize slidable connection, namely, a sliding pair is formed. Thus, the movable roller mechanism can be linearly moved in the front-rear direction with respect to the fixed roller mechanism by the sliding connection.

Referring to fig. 3, the device further comprises a reset mechanism, which mainly comprises a stop block 10 and a spring 9; the stopper 10 is screwed to the lower surface of the rear end of the plate 6. Two concentric holes are arranged between the fixed base 13 and the stop block 10, and the front end and the rear end of the spring 9 are respectively connected in the holes of the fixed base 13 and the stop block 10. In addition, the rear end of the spring 9 is also connected with a bolt 11, and the bolt 11 passes through the rear end wall of the stop block 10 to be connected with the rear end of the spring 9; the bolt 11 serves to fix the spring 9 in the axial direction so as to prevent the spring 9 from popping out when the spring is suddenly loosened in a highly contracted state, thereby ensuring the stability of the mechanism and the safety of the hands of an operator.

Wherein, the utility model also comprises a handle 12, the upper end of the handle 12 is connected with the lower end of the block 10; the cross section of the handle 12 is circular arc, the opening of the circular arc faces the barrel 3 of the gun body, and the circular arc convex part on the back of the handle is used for pressing by the palm. In use, the gun barrel 3 is held by the four fingers, and the palm is attached to the arc convex part and applies force, so that the straight line movement can be pushed.

Referring to fig. 1, a fixed base 13 is sleeved on a gun barrel 3 in an interference fit manner, a belt pulley 5 is arranged above a flat plate 6, and the axis of the belt pulley is fixed by a trapezoidal bolt; and the driving motor of the electric gun transmits power to the pulley 5 through the gear transmission structure and drives it to rotate. The part sleeved on the gun barrel 3 can not move in the axial direction, so that the stability of the rolling gun in working is ensured.

The fixed roller 1 is fixed on the L-shaped bracket 8 through the rolling bearing 7, and the fixed roller 1 is not subjected to too much force, so that the lower end of the L-shaped bracket 8 is fixedly clamped in the through hole of the fixed base 13 to meet the strength requirement. Specifically, the lower end of the bracket 8 passes through the sliding groove to be connected with the fixed base, and the length of the sliding groove is adapted to the distance of the movable roller mechanism moving back and forth.

When the rolling gun is operated, the back of the handle 12 is pressed by hands, the movable roller 2 can translate in a direction away from the gun barrel 3, but the translation range is limited by the contact between the sliding block 14 and the stop block 10; in this state, a larger gap is generated between the movable roller 2 and the fixed roller 1, so that the skylight sealing strip of the gun head can be conveniently clamped into the root part of the roof metal plate along the belt pulley 5.

Then the handle 12 is loosened, the fixed roller 1 and the movable roller 2 clamp the sheet metal part tightly, and at the moment, the sealing strip can automatically clamp the root of the main sheet metal part along the edge of the sheet metal part as long as the belt pulley 5 is rotated, so that the whole sealing strip installation process is completed.

Referring to fig. 2, preferably, the fixed roller 1 is rotatably coupled to the upper end of the bracket 8 through a rolling bearing 7; the movable roller 2 is also rotatably connected to the base of the plate 6 by means of a rolling bearing 7.

The embodiments of the present invention have been described in conjunction with the accompanying drawings and examples, the structures of which are not intended to limit the present invention, and those skilled in the art can make modifications as required, and all changes and modifications within the scope of the appended claims are within the scope of protection.
