Coupling arrangement for workpiece-taking of plastic jetting-moulding machine

Abstract

The invention discloses a connection device for picking up parts from an injection molding machine, which includes a bracket structure, one end of which is provided with a connection part fixed to a manipulator, and is characterized in that the bracket structure includes a ring-shaped bracket and at least one transverse A bracket, one side of the ring-shaped bracket is provided with a connecting part, and installation holes are intermittently distributed along the ring edge of the bracket, and at least one slideway hole for the sliding of the pick-up mechanism is provided on the horizontal bracket, and the horizontal bracket is installed through the The cooperation of the channel, the slideway hole and the bolts and nuts is fixedly connected with the ring support. The present invention utilizes the combination of the installation hole on the ring-shaped support and the slideway hole on the transverse support to expand the range of motion of the pick-up mechanism installed on the transverse support, increase the flexibility of pick-up, and improve the use of the connecting device range, to avoid frequent replacement, on the other hand, according to the needs of pick-up, multiple pick-up mechanisms can be installed on the same horizontal bracket to improve work efficiency.

Description

technical field [0001] The invention relates to an accessory of an injection molding machine, in particular to a connection device installed on a manipulator of an injection molding machine for connecting a pick-up fixture. Background technique [0002] On the injection molding machine, when the finished workpiece is demolded, the manipulator is generally used to pick up the piece. The pick-up mechanism (such as a fixture, suction cup, etc.) is used as an accessory of the manipulator, and is installed on the manipulator through a connecting device to cooperate with the manipulator. [0003] The above-mentioned connection device can be a connection plate, which is provided with a mounting hole for connecting with the manipulator, and is fixedly provided with a pick-up mechanism. However, due to the different types or models of workpieces, the working positions of the pick-up mechanism are also different. Changes, such as when the pick-up mechanism is a fixture, the clamping d...

[0005] However, as mentioned above, the range of motion of the pick-up mechanism is formed by the position of the chute of the two brackets. Taking the vertical bracket fixed on the horizontal bracket as an example, the range of motion is the center line of the horizontal bracket, the length of the vertical bar × the horizontal bar The area obtained by the length, due to the limitation of the position of the fixing hole, the longitudinal bar can slide on the horizontal bar, but the longitudinal position of the longitudinal bar cannot be adjusted. If the pick-up position exceeds the position reached by the length of the longitudinal bar, the connecting device needs to be replaced ; On the other hand, the bracket is fixed with the manipulator through the mounting hole at one end, and the force point is only on one end of the bracket, which has poor stability. If the bracket connection part is arranged in the middle, the range of the bracket’s outward extension is further limited. In other words, In order to provide sufficient supporting force, the length of the bracket is limited, and the range of motion of the pick-up mechanism is relatively limited
