Description

Technical Field

[0001] This utility model relates to a clamping device, specifically a swing arm clamping device for a special casting grinding equipment. Background Technology

[0002] With the advancement of Industry 4.0 and the booming development of the casting industry in my country, the entire casting process, from raw materials to finished products, is rapidly transforming towards automation, digitalization, and greening. In recent years, the cleaning and grinding of casting parts has faced labor shortages. Therefore, some automation companies have introduced automated grinding equipment into this process. These automated grinding devices mainly fall into two categories: one with a fixed grinding wheel, where the equipment grips the workpiece and approaches the wheel for grinding; and the other with a fixed workpiece, where the equipment carries the grinding wheel mechanism to the workpiece for grinding. Both methods require the product to be securely fixed in the tooling position.

[0003] However, most clamping methods currently on the market are designed to mimic machining fixtures. They are positioned based on the workpiece's shape, and then clamping is applied to the fixture or an external clamping device is added. This method has poor compatibility, and each fixture requires a pneumatic or hydraulic clamping device, resulting in high costs. For casting customers, whose products are often diverse and produced in small batches, this type of fixture, which requires frequent changes, is not suitable.

[0004] Furthermore, if an external clamping structure is installed, the equipment may tilt due to unidirectional force, which will not only cause grinding errors but also affect the stability of grinding. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing external clamping structures are prone to causing grinding errors and affecting grinding stability, and to provide a swing arm clamping device for special casting grinding equipment.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0013] Furthermore, an adapter rod is rotatably mounted on the clamping arm, and the clamping rod is fixedly mounted on the bottom of the adapter rod.

[0014] Furthermore, the connecting rod is L-shaped;

[0015] The output end of the swing arm cylinder is rotatably mounted at the intersection of the long arm and the short arm of the connecting rod.

[0016] The short arm of the connecting rod is rotatably mounted on the side of the clamping arm, and a hydraulic damper is provided between the long arm of the connecting rod and the side of the clamping arm; the cylinder of the hydraulic damper is connected to the clamping arm, and the piston of the hydraulic damper is in contact with the long arm of the connecting rod.

[0017] Furthermore, the sliding seat is provided with a limiting block;

[0018] The turntable door is equipped with a sheet metal protective cover.

[0019] Furthermore, the sliding seat is provided with a protective shell, and the swing arm cylinder is located inside the protective shell.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] The swing arm clamping device for special casting grinding equipment provided by this utility model is directly installed on both sides of the turntable door of the double-station turntable and is integrated with the double-station turntable. It can ensure the stability of workpiece clamping, help reduce grinding errors, and improve the stability of the grinding process. At the same time, the sliding seat driven by the linear cylinder moves up and down on the turntable door to realize the clamping rod clamping the workpiece. Combined with the swing arm cylinder and connecting rod, the position of the clamping arm is adjustable, making it suitable for clamping most workpieces. Attached Figure Description
