Clamping device

Abstract

The invention provides a clamping device, which comprises a fixed clamping mechanism which is suitable for being fixedly connected with a frame, and is provided with a positioning structure for pre-assembling a work piece to be processed; a moving clamping mechanism provided with a matching structure matched with the positioning structure and used for clamping the work piece to be processed; a driving device, which comprises a driving main body which is suitable for being fixedly connected with the frame and an execution component which is arranged on the driving main body, wherein the execution component moves linearly with respect to the driving main body; a transmission mechanism connected with the execution component and the moving clamping mechanism; wherein the transmission mechanism drives the moving clamping mechanism to move in the direction close to or away from the positioning structure under the action of the execution component, so that the movement direction of the moving clamping mechanism is mutually angular with the movement direction of the execution component. The device has the advantages that the execution component is not easily pushed back, and the matchingstructure can be easily maintained in a state of matching with the positioning structure for clamping the work piece to be processed, so that the work piece to be processed can be stably clamped, andthe processing effect of the work piece to be processed is ensured.

Description

technical field [0001] The invention relates to the technical field of clamps, in particular to a clamping device. Background technique [0002] Evaporators and condensers are important components of air conditioners. Heat exchange tubes (usually copper tubes) are important components of condensers and evaporators. They are used to form air-conditioning heat dissipation waterways. High-temperature or low-temperature water flows in the air-conditioning waterways to exchange heat with the external environment to realize air-conditioning cooling at room temperature. the regulating effect. Some heat exchange tubes usually require tube end forming process, such as flaring or shrinking the tube end, etc. The flaring equipment usually uses an oil cylinder as a moving part, and the theoretical force of the oil cylinder can reach several tons. If the heat exchange tube is not clamped, the position If there is a slight mistake, the oil cylinder will push the diameter of the waste he...
