Description

Belt material conveying line high accuracy positioning mechanism

Technical Field

The utility model relates to a material positioning device, in particular to a high-precision positioning mechanism of a belt material conveying line.

Background

On an automated production line, it is a common way to use a belt to transport the parts to be machined. In order to ensure the machining precision of the part at the machining station, it is necessary to position the part when it reaches the machining station via belt transport.

Detailed Description

Referring to fig. 1-3, this embodiment includes the stopper 2 of installing at conveyor 1 terminal, horizontal location cylinder 3 is installed respectively to conveyor 1 terminal both sides, conveyor 1 terminal top is provided with vertical location cylinder 4, vertical location cylinder 4 installs on support 5, vertical location cylinder 4's piston end is perpendicular downwards, vertical location cylinder 4's piston end detachable installs horizontal mounting panel 6, be provided with logical groove 7 on the horizontal mounting panel 6, roof 8's bottom is provided with screw rod 9, screw rod 9 grafting is fixed in logical groove 7 and through the locking of nut 10, roof 8 bottom is provided with two spouts 11, spout 11 is parallel with the direction of action of horizontal location cylinder 3, be connected with slider 13 through spring 12 in the spout 11, threaded connection has montant 14 on the slider 13, the joint has limiting plate 16 through buckle 15 joint on the montant 14. Before the positioning operation is performed by using the positioning mechanism, firstly, a top plate 8 with a proper model (the top plates 8 with different models are positioned at intervals between different sliding grooves 11 and the relative positions of different vertical rods 14) is selected according to the shape of a part and is installed on the horizontal installation plate 6, and the relative fixed angle of the horizontal installation plate 6 is adjusted, so that the vertical rods 14 are aligned with the plugging positions on the part. When the parts are transmitted to the limiting block 2 through the conveying belt 1 to stop, the vertical positioning cylinder 4 moves downwards to drive the vertical rods 14 to be inserted into the preset part insertion positions. Then, one of the two horizontal positioning cylinders 3 is selected to push the part according to the shape and the relative position of the part, and the other horizontal positioning cylinder 3 is kept in a static state. The vertical bar 14 moves synchronously with the part during the pushing of the part to keep the relative angle constant during the movement of the part. After the edge of the part is in stable contact with the other horizontal positioning cylinder 3 which is kept in a static state, the vertical positioning cylinder 4 moves upwards to drive the vertical rod 14 to separate from the part, and finally the horizontal positioning cylinder 3 which performs pushing operation resets to complete positioning operation.

The outside of the vertical rod 14 is wrapped with a rubber layer 17, and the rubber layer 17 is used for protecting parts and avoiding the relative positions of the parts and the vertical rod 14. The bottom of the vertical rod 14 is connected with a cone 18, and the cone 18 plays a guiding role, so that the vertical rod 14 can be conveniently and smoothly inserted into a preset inserting position.

The inside walls at both ends of the chute 11 are provided with rubber deceleration strips 19, and when the slider 13 moves to both ends of the chute 11, the slider 13 is in sliding contact with the rubber deceleration strips 19. When the part is about to reach the positioning position, the sliding friction force between the sliding block 13 and the rubber deceleration strip 19 is used for applying moving resistance, so that the moving speed of the part is reduced, and the damage to the part caused by high-speed impact and the possible tiny displacement and movement of the part are avoided.

The limiting block 2 is made of polyurethane elastomer, and a negative pressure suction hole 20 is formed in one side, facing the conveying belt 1, of the limiting block 2. When the part reaches the position of the limiting block 2, negative pressure suction force is generated through the negative pressure suction hole 20, so that the stable contact state of the part and the limiting block 2 is maintained.
