Clamping device

Abstract

The invention provides a clamping device. The clamping device comprises a fixture bottom plate, clamping oil cylinders, bearing supports, supporting rolling wheels and fixing clamping blocks; the fixture bottom plate is arranged at the bottom of a main frame of the clamping device, and the four bearing supports are arranged in the main frame and arranged on the upper side, the lower side, the leftside and the right side of the main frame; and the bearing supports are installed on the main frame through polished shafts and linear bearings, therefore, the bearing supports installed on the upperside and the lower side of the main frame can move in the vertical direction, and the bearing supports installed on the left side and the right side of the main frame can move in the horizontal direction. According to the clamping device, the supporting rolling wheels are connected with the oil cylinders and the linear bearings through the bearing supports, the four supporting rolling wheels arearranged in two rows and can better clamp a workpiece and share the longitudinal force of the workpiece, self-centering and aligned clamping are achieved, and materials can pass through the clamping device while the materials are clamped.

Description

technical field [0001] The invention relates to the technical field of clamps, in particular to a clamping device that ensures the passage of materials while clamping. Background technique [0002] In the fixture, the device used to prevent the displacement or vibration of the workpiece during processing is called the clamping device. The following requirements should be considered when designing the clamping device: [0003] 1. The position of the workpiece does not change during the clamping process. [0004] 2. The clamping force should be able to ensure that the workpiece will not be displaced or vibrated during processing, and will not crush the surface of the workpiece or cause deformation. [0005] 3. The operation is convenient and the clamping action is fast to improve productivity; the structure is simple and easy to manufacture to reduce the cost of the fixture. [0006] 4. Self-locking, that is, after the original force is removed, the clamping state of the wo...

Problems solved by technology

[0008] However, for the clamping processing of longer workpieces, it is necessary to maintain the clamping without stopping the cutting process to ensure its longitudinal fixation, and the prior art lacks corresponding clamping devices
