[0002] The existing bending machine automation on the market is generally combined with industrial robots to achieve highly automated integration, high precision, and cost reduction and efficiency improvement. Since the rear stop finger of the robot generally requires sensors, cylinders, etc. to achieve, the size of the robot stop finger is much larger than the size of the manual bending stop finger, which causes a certain waste of the performance of the machine tool. In addition, when the bending machine has both robot stop fingers and manual stop fingers, the size of the two stop fingers may be different, which also causes certain troubles for the application of the system and reduces production efficiency. Especially for the current small-tonnage bending machines driven by electric or hydraulic drives, due to limited space, the existing stop fingers are large in size and occupy a relatively large space, resulting in difficulties in assembly.

For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0017] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0018] like Figure 1 As shown, an automated rear positioning finger stopper for a small-tonnage bending machine includes a base 1, a cylinder 2, a linear guide 3, a sensor 4, a linear guide positioning block 5 and a finger stopper slide 6. The cylinder is mounted on the base, and the piston rod of the cylinder is connected to one side of the finger stopper slide. Specifically, two baffles 12 are provided at the front of the base, and a guide groove 13 is provided between the two baffles. The front end of the finger stopper slide passes through the guide groove, and the finger stopper slide is flush with the base. The other side of the finger stopper slide is slidably matched with the linear guide, and the linear guide is mounted on the side of the linear guide positioning block. The linear guide positioning block is fixed on the base, and the rear end of the finger stopper slide is connected to the sensor. This structure can achieve the same size of the robot finger stopper as the manual bending finger stopper in the case of small tonnage and limited space size, so that the performance of the bending machine can be brought into play to a greater extent and the efficiency can be improved.

[0019] In order to protect the internal components, a protective cover 7 is fixed on the base.

[0020] In order to facilitate the quick connection between the cylinder and the sensor, a sensor plug 8 and a pneumatic adapter 9 are provided on one side of the base. The sensor plug and the pneumatic adapter are fixed to one side of the base through a connecting plate 10. The sensor plug is connected to the sensor through a wire, and the pneumatic adapter is connected to the cylinder through a pneumatic hose.

[0021] In order to fix the device on the horizontal guide rail of the Z-axis of the bending machine, a top screw block is provided at the bottom of the base, and the internal thread of the top screw block is connected with a top screw.

[0022] In order to protect the device, a buffer block 11 is installed on the side of the base.

[0023] The base is hinged with the linear guide slider of the Z-axis horizontal guide of the bending machine, and is connected to the driving module such as the motor board of the finger stopper by pins, set screws, etc., which can adjust the gap between the motor, gears, racks and other parts of the driving module and the vertical adjustment. In the horizontal direction, the upper end of the top screw block is hinged with the base, and two set screws are arranged in the horizontal direction to vertically lock the slider on the Z-axis horizontal guide to realize the adjustment function of the finger stopper in the horizontal direction; in terms of pneumatics, one end of the pneumatic hose is connected to the pneumatic solenoid valve and the other end is connected to the pneumatic adapter, and the other end of the pneumatic connector is connected to the pneumatic pipe connector, and the pneumatic pipe connector is connected to the cylinder. When the pneumatic solenoid valve is introduced with compressed air, the cylinder rod of the cylinder extends out, and the finger stopper slide is extended in the horizontal direction through the linear guide; the front section of the sensor at the other end also has a probe with a compression device, and the analog quantity is detected by the compression amount, so as to detect whether the plate has been positioned in place; the tail end of the sensor is welded to the cable of the sensor plug, and the sensor plug and the pneumatic adapter are fixed on the connecting plate together, and the connecting plate is hinged to the base. This structure can save space better, integrate the air pipe and cable in the finger, and facilitate fixation, maintenance and disassembly. Buffer blocks are set on both sides of the finger, and the fixing hole and the shield are shared, which can not only reduce the processing of one threaded hole and one screw assembly, but also reduce the working hours and costs.

[0024] The small-tonnage bending machine has a high degree of integration, and parts such as the base and the shield have composite functions, so that the overall size of the finger can be the same as that of the finger of the small-tonnage manual bending machine. Customers can switch between robot and manual modes at any time during bending work without complex operations such as switching models in the control system. At the same time, the small-tonnage bending machine also has a clever mechanical structure, does not require ultra-high processing precision, is easy to assemble, and has low cost.

[0025] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
