Description

Technical Field

[0001] The utility model belongs to the technical field of auxiliary arms, and in particular relates to an auxiliary arm. Background Art

[0002] An auxiliary arm is a device used to provide additional assistance, usually used in industrial production lines or assembly lines. They are designed to reduce the labor burden of workers and improve work efficiency. An auxiliary arm usually consists of an adjustable robotic arm, a support device and a control system to adapt to different work tasks and workpieces.

[0003] However, the existing auxiliary arms also have certain shortcomings. First, the existing auxiliary arms are mostly driven by simple gears, motors and other structures to complete the deflection operation of fixed devices such as electromagnetic chucks and clamps. Due to the influence of external factors such as inertia, the electromagnetic chucks, clamps and other fixed devices may cause unnecessary deflection problems.

[0004] Secondly, the existing auxiliary arms mostly use manual operation to lift and reset the auxiliary arms, electromagnetic chucks, etc. for taking and using workpieces and materials, which is obviously inconvenient for operators to use. Summary of the invention

[0005] The utility model aims to provide an auxiliary arm, which solves the problem that the existing auxiliary arms mostly use a simple driving method of gears, motors and other structures to complete the deflection operation of fixed devices such as electromagnetic suction cups and clamps, and the influence of external factors such as inertia will cause unnecessary deflection of fixed devices such as electromagnetic suction cups and clamps; and solves the problem that the existing auxiliary arms mostly use manual operation to lift and reset the auxiliary arms, electromagnetic suction cups, etc. for the use of workpieces and materials, which is inconvenient for operators to use.

[0006] In order to achieve the above-mentioned purpose, the utility model provides an auxiliary arm, including a base, the upper end of the base is fixedly connected to a support frame, a support shaft is installed inside the support frame through a bearing, the upper end of the support shaft is fixedly connected to a gear plate, the gear plate is rotatably connected to the support frame, the outer side of the support frame is fixedly sleeved with a mounting plate, a motor is fixedly installed on the upper end of the mounting plate, a positioning hole is opened at the lower end of the gear plate, a telescopic rod is slidably connected to the inside of the mounting plate, the upper end of the telescopic rod is fixedly connected with a positioning ball, the positioning ball is slidably connected to the positioning hole, the outer side of the telescopic rod is fixedly sleeved with a fixing plate, and a spring is arranged on the outer side of the telescopic rod;

[0007] The upper end of the gear plate is fixedly connected to a mounting frame, the inner side wall of the mounting frame is rotatably connected to a traction plate, the lower end of the traction plate is fixedly connected to an auxiliary arm, the horizontal portion of the auxiliary arm is provided with an electromagnetic suction cup, the interior of the mounting frame is rotatably connected to a rotating shaft, the rotating shaft is fixedly connected to the traction plate, the side end of the mounting frame is fixedly connected to a mounting cylinder, the outer side of the rotating shaft is provided with a torsion spring, the back side of the mounting frame is fixedly installed with a motor 2, the outer side of the output end of the motor 2 is fixedly sleeved with a winding wheel, the surface of the winding wheel is provided with a traction line, and the traction line is fixedly connected to the traction plate.

[0009] The starting motor drives the output shaft to rotate forward to drive the gear to rotate. Under the meshing relationship, the gear drives the gear plate to rotate, and then drives the mounting frame to rotate, so as to drive the auxiliary arm to rotate, so as to rotate the electromagnetic suction cup, and finally drives the material, workpiece, etc. to deflect, so that the material, workpiece, etc. are in the stacking area. During the process, the inner wall of the positioning hole squeezes the positioning ball to push the telescopic rod to move, and the spring is deformed, so that the positioning ball finally leaves the positioning hole. Under the action of force, the positioning ball slides along the surface of the gear plate. When the positioning ball slides into the next positioning hole, the spring restores the deformation to push the positioning ball into the positioning hole, limit the gear plate, and then finely control the position of the electromagnetic suction cup;

[0010] Close the electromagnetic suction cup to allow materials, workpieces, etc. to fall into the stacking area, start motor 1 to drive the output shaft to rotate in the opposite direction, and similarly, the gear plate will eventually drive the electromagnetic suction cup to rotate back to the work station, start motor 2 to drive the output end to rotate in the opposite direction to drive the reel to rotate, and pay out the traction line.

[0026] like Figure 1 , Figure 2 , Figure 3As shown, four evenly distributed reinforcing ribs are fixedly connected to the surface of the support frame 2, and each reinforcing rib is fixedly connected to the base 1. The arrangement of the reinforcing ribs can ensure the installation stability of the support frame 2. A gear 7 is fixedly sleeved on the outer side of the output shaft of the motor 6, and the gear 7 is meshed with the gear plate 4.

[0028] The specific implementation process of the utility model is as follows: start the electromagnetic suction cup 16 to adsorb materials, workpieces, etc., start the motor 20 to drive the output end to rotate in the forward direction, so as to drive the winding wheel 21 to rotate, and reel the traction line 22, thereby pulling the traction plate 14 to deflect, so as to drive the rotating shaft 17 to rotate, and the torsion spring 19 is deformed, and when the traction plate 14 deflects, the auxiliary arm 15 can be driven to deflect, thereby driving the electromagnetic suction cup 16 to deflect, so that the electromagnetic suction cup 16 is away from the work station;
