Description

Technical Field

[0001] This utility model relates to the field of clamping cylinder tools, and in particular to an electric clamping cylinder tool. Background Technology

[0002] Power tools play a vital role in modern industry. Driven by electricity, they greatly improve work efficiency and reduce the intensity of manual labor. Power tools require relatively low investment.

[0003] The prior art involves the following three applications:

[0004] Application 1: Clamping Cylinder (CN218913326U) This utility model provides a clamping cylinder, including a cylinder, a housing, and clamping arms. A drive shaft is rotatably mounted inside the housing. The clamping arms are fixedly mounted at both ends of the drive shaft. A crank is fixedly mounted in the middle of the drive shaft, and a push-pull rod for driving its swing is connected to the crank. A baffle and a connecting rod are mounted at the lower end of the push-pull rod. The cylinder has a piston rod with a cylindrical cavity at its end. The connecting rod is slidably mounted inside the cylindrical cavity, with elastic support between the bottom end of the connecting rod and the top of the cylindrical cavity. A limiting ring corresponding to the baffle is mounted around the outer side of the piston rod. Adjustment mechanisms for vertically adjusting the position of the limiting ring are symmetrically arranged on both sides of the limiting ring. In this utility model, the position of the limiting ring can be adjusted vertically via the adjustment mechanisms to meet the needs of adjusting different upward swing angles of the clamping arms. The cylinder does not need to be disassembled during adjustment, improving the convenience of debugging.

[0005] Application 2: Electric Gripper (CN213946481U) This utility model relates to the field of gripper technology, providing an electric gripper, including a mounting base, a gripping mechanism, a driving mechanism, and a guiding mechanism. The gripping mechanism includes gripping fingers and a rack, with the rack fixedly connected to the gripping fingers. The driving mechanism includes a drive motor and an output gear, with the output gear connected to the output shaft of the drive motor and connected to the rack, driving the rack to perform linear reciprocating motion. The guiding mechanism includes a guide rail and a slider that slides with the guide rail. The guide rail and the rack are arranged parallel to each other. One of the guide rail and the slider is fixedly connected to the gripping fingers, and the other of the guide rail and the slider is fixedly connected to the mounting base. The electric gripper provided by this utility model uses a rack and gear combination to achieve a large stroke movement of the gripping fingers, and uses a guide rail and slider combination to improve the stability of the gripping finger movement, thereby solving the problems of small gripping stroke and low movement stability in existing grippers.

[0006] Application 3: Long-stroke Electric Gripper (CN216859769U) This application provides a long-stroke electric gripper, including a support base, a pair of gripping assemblies, and a drive assembly. The support base includes a support portion located between the pair of gripping assemblies. The drive assembly includes a motor, a nut, and a pusher. The rotor shaft of the motor has a protruding portion that extends into the support base. One end of the protruding portion away from the rotor of the motor passes through the pusher and is rotatably connected to the support portion. The nut is threaded onto the protruding portion. The pusher is sleeved on the nut and is hinged to the pair of gripping assemblies respectively. The long-stroke electric gripper provided in this application uses a lead screw and nut pair formed by the rotor shaft of the motor and the nut, avoiding the problem of difficulty in ensuring concentricity between the rotor shaft and the lead screw in related technologies. Furthermore, since the two ends of the protruding portion are supported on the rotor and the support portion respectively, the pusher driven by the nut is less prone to wobbling during movement, thereby solving the problems of poor concentricity between the rotor shaft and the lead screw and poor stability of the pusher during movement.

[0007] The technical challenges of this type of equipment are: electric grippers use electricity as the energy medium, resulting in relatively low clamping force, making them suitable only for lightweight and small objects, thus limiting their applicability; these grippers are best suited for operation in cleanroom environments and are not suitable for use in automotive welding production environments, thus limiting their application scope.

After the above steps, housing 9-2 is installed onto housing 9-1 and locked, thus ensuring that the upper part of the electric clamping tool is installed.

[0040] The manual power-off mechanism 7 includes a dust cover 7-1 and a mounting shaft 7-2. Installation involves fitting the mounting shaft 7-2 onto the front end of the lead screw 4-5. Before installation, sealing rings 6-1 and 6-2 are installed onto the mounting shaft 7-2 to ensure a tight seal after installation. The dust cover 7-1 is then installed onto the cylinder housing 9. The mechanism is manually opened in the event of a power outage using an Allen wrench through the Allen hole at the front end of the lead screw 4-5. The manual power-off mechanism 7 is designed to provide both sealing and manual opening functionality after a power outage.

[0041] The control system 8 includes a motor 8-1, an encoder 8-2, a mounting plate 8-3, and a driver 8-4.

[0043] The tool is now installed.

[0044] The tool is dustproof by means of a sealing ring and the groove at 9-1 on the housing and the boss at 9-2 on the housing, thus forming the dustproof function of the entire tool and making it suitable for various industries.

[0045] The motor 8-1 is used as the power source to drive the lead screw 4-5 to rotate, which causes the lead screw nut 4-3 to move linearly, thereby driving the rotating shaft 3-1 on the elbow to rotate. Because the elbow can provide greater clamping force than other mechanisms, the electric clamping tool is more energy-efficient, quieter, and runs more smoothly than the cylinder.
