[0002] Automated production refers to a modern production method that uses advanced technologies such as computers, controllers, sensors, and actuators to achieve automatic control and optimization of the production process, improve production efficiency, precision, and quality, and reduce human intervention and resource waste. In the process of automated production, it is necessary to use a grasping device to grasp the workpiece to facilitate the transfer and transportation of the workpiece, which is suitable for automated production.
[0003] At present, when using the workpiece grasping device for automated production, if the grasping force is too large, it is easy to cause damage to the workpiece, thereby reducing the yield rate and reducing the production profit of the enterprise. For this reason, we propose a workpiece grasping device for automated production. Utility Model Content
[0004] The purpose of the utility model is to provide a workpiece grasping device for automated production, which has the advantages of avoiding damage to the workpiece due to excessive grasping force during the process of grasping the workpiece in automated production, improving the yield rate of the workpiece, and having a wide range of grasping workpieces and strong applicability. It solves the problem that the workpiece grasping device currently used in automated production is prone to damage to the workpiece when the grasping force is too large during use, thereby reducing the yield rate and reducing the production profit of the enterprise.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automated production workpiece grasping device, comprising a hollow cross plate, a bidirectional screw rod rotatably installed inside the hollow cross plate, a rotating motor fixedly installed on one side of the outer surface of the hollow cross plate, threaded sliders symmetrically and movably sleeved on the outer surface of the bidirectional screw rod near the two ends, connecting rods are fixedly connected to the lower surfaces of the two threaded sliders, and the ends of the two connecting rods located below the hollow cross plate are fixedly connected to fixed sleeves, coil springs are fixedly connected inside the two fixed sleeves, telescopic rods are fixedly connected at the ends of the two coil springs, fixed clamps are fixedly connected to the ends of the two telescopic rods, and contact switches are arranged inside the two fixed sleeves.
[0006] Preferably, the end of the output shaft of the rotating motor and the end of the bidirectional screw rod are fixedly connected.
[0007] Preferably, a threaded hole is provided at the middle position of the upper surface of the hollow horizontal plate.
[0008] Preferably, nuts are welded on the outside of the two fixed sleeves, screws are movably inserted inside the two nuts, and one end of the two screws located inside the two fixed sleeves is fixedly connected to the outside of the two contact switches respectively.
[0009] Preferably, the outer surfaces of the two screws are both provided with scale lines.
[0010] Preferably, silicone pads are fixedly installed on the inner sides of the two fixing splints.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. The utility model achieves the effect of avoiding damage to the workpiece due to excessive grasping force and improving the yield rate of the workpiece in the process of automatic production of grasping the workpiece by arranging a hollow cross plate, a bidirectional screw rod, a threaded slider, a rotating motor, a fixed sleeve, a spiral spring, a telescopic rod, a fixed clamping plate and a contact switch. The rotating motor drives the bidirectional screw rod to rotate, so that the two threaded sliders move towards each other, and the two fixed clamping plates clamp the two sides of the workpiece to complete the grasping work, and the telescopic rod slides into the fixed sleeve, and the spiral spring is compressed. When the telescopic rod contacts the contact switch, the rotating motor stops working to control the grasping force for the workpiece and prevent the workpiece from being damaged due to excessive grasping force.
[0013] 2. The utility model achieves the effect of facilitating the adjustment of the gripping force of the workpiece by setting a screw and a nut. By rotating the screw to drive the contact switch to move, the distance between the contact switch and the telescopic rod can be adjusted. Therefore, when the workpiece is gripped through the fixed splint, the distance the telescopic rod moves inside the fixed sleeve and the degree of compression of the coil spring can be controlled, thereby controlling the gripping force of the workpiece.
[0014] 3. The utility model achieves the effect of preventing the fixed splint from causing surface wear when grabbing the workpiece by arranging the silicone pad. The silicone pad has a soft texture. When the fixed splint grabs the workpiece, the fixed splint contacts the workpiece through the silicone pad, thus preventing the surface wear of the workpiece.
