Detailed ways

As shown in the figure, the fixture for welding the middle groove of the scraper conveyor includes a fixed end plate 1, a conical pin 2, a support plate 3, a moving end plate 4, a hydraulic cylinder 5, a guide rail 6, a bottom plate 7, and a workbench 8. The fixed end plate 1 is installed on the left end of the bottom plate 7, the conical pin 2 is installed on the fixed end plate 1 and the movable end plate 4, two support plates 3 are installed in the middle of the bottom plate 7 in parallel, the movable end plate 4 and the hydraulic cylinder Link to each other, at the right end of base plate 7, be contained between the two tracks of guide rail 6, guide rail 6 is contained on the base plate 7, and base plate 7 is on the workbench 8.

The steps of using the welding fixture for the middle groove of the scraper conveyor are as follows:

1) Put the middle plate 10 on the supporting plate 3, put the two channel side steels 9 on both sides of the middle plate 10, push the channel side steel 9 towards the direction of the fixed end plate 1, and make the curved surface grooves of the channel side steel 9 contact Conical pin 2, and then continue to push until the six conical pins 2 on the fixed end plate 1 play a positioning role to limit the channel side steel to a fixed position;

2) Start the hydraulic system, so that the push rod of the hydraulic cylinder 5 pushes the movable end plate 4 under the action of hydraulic oil, so that the movable end plate 4 is pressed against the channel side steel 9 along the guide rail 6, and the six cones on the movable end plate 4 Pin 2 is inserted into the groove of channel side steel 9 to play a positioning role, and the workpiece is clamped with the movement of movable end plate 4;

3) Weld the two sides of the middle plate with the channel side steels on both sides. After the welding is completed, press the unloading button of the hydraulic system, and the push rod of the hydraulic cylinder 5 will be retracted under the action of the hydraulic oil, remove the workpiece, and then clamp the next one. pieces.

The fixed end plate 1 is an L-shaped steel plate with six holes on its vertical surface for holding six conical pins 2. Their positions are determined by the curved shape of the channel side steel 9, and a group of three forms a "3" " font and reverse 3 " font, three holes are arranged on its horizontal plane, in order to pack into screw and base plate 7 and fix.

The conical pin 2 is a pin with a thread on one end and a conical shape on the other. The threaded end is inserted into the holes of the fixed end plate 1 and the movable end plate 4, and the conical end is inserted into the curved groove of the side steel to form a positioning groove. Help the role of steel.

The support plate 3 is a rectangular steel plate, and two support plates 3 are installed in the middle of the base plate 7 in parallel to support the middle plate 10, so that the middle plate 10 is just positioned at the waist position of the two channel side steels 9.

The moving end plate 4 is a steel plate similar to the vertical surface of the fixed end plate 1. It has six holes for holding six conical pins 2, and a group of three forms a "3" shape and a reverse 3" shape. There is an installation space in the center of the plate, which is used to connect with the hydraulic cylinder 5. There are two protruding feet on both sides of the lower part of the moving end plate 4 to match the guide rail 6. It is installed between the two tracks of the guide rail 6. It can be Slide freely on the guide rail 6.

The hydraulic oil cylinder 5 is mounted on the central position of the movable end plate 4, and is connected with the hydraulic system, and pushes the movable end plate 4 to slide freely on the guide rail 6 during operation.

The guide rail 6 is mounted on the bottom plate 7 to provide the moving track of the movable end plate 4 . Base plate 7 is a rectangular steel plate, is contained on the workbench 8, provides installation platform for other parts. Workbench 8 is a frame-type table top, and the purpose is to raise the work surface and reduce the bending degree of the operator.

The working process of the fixture is: when welding the middle groove, place the middle plate 10 at a suitable position on the support plate 3, put the two side steels 9 on both sides of the middle plate 10, and push the side towards the fixed end plate 1 Steel 9, make the curved surface groove of channel side steel 9 contact the conical pin 2, continue to push until six conical pins 2 play a positioning role, the channel side steel is limited on the fixed position. Start the hydraulic system, so that the push rod of the hydraulic cylinder 5 pushes the movable end plate 4 under the action of hydraulic oil, so that the movable end plate 4 is pressed to the groove side steel 9 along the guide rail 6, and the six conical pins 2 on the movable end plate 4 Insert it into the groove of the side steel 9 to play a positioning role. With the movement of the movable end plate 4, the workpiece is clamped. At this time, the welding of the middle groove can be started: the two sides of the middle plate are welded together with the side steel on both sides. When the welding is finished, press the unloading button of the hydraulic system, and the push rod of the hydraulic cylinder 5 is retracted under the action of the hydraulic oil, the workpiece is loosened, the workpiece is removed, and the next workpiece is clamped again, and the operation is repeated.
