Problems solved by technology

Since the outer surface of most workpieces needs to be processed, in order to facilitate the processing of the workpiece by the machine tool, the current clamping device has a complicated structure and is inconvenient to operate, and it is difficult to perform centering clamping on the workpiece, or the centering clamping is not firm enough. The effect of centering and clamping is not good, which greatly reduces the processing efficiency and has a great impact on production

Abstract

The invention discloses a transmission centering clamping device with a rotation axes and relates to a centering clamping device. The transmission centering clamping device with the rotation axes comprises a machine frame, an upper die block, a middle die block, a lower die block, a rotation handle, two clamping claws and two ejecting blocks. The upper die block, the middle block and the lower die block are connected through bolts. Nuts of the bolts are embedded in the lower die block which is connected with the rotation handle in a welded mode. The two clamping claws are respectively hinged with the machine frame. Screws are respectively arranged at the lower ends of the two clamping claws. Nuts of the screws are respectively attached with two ends of the middle die block. A through hole is formed in the top of the upper die block. The two ejecting blocks are arranged in the through hole. A reset spring is arranged between the two ejecting blocks which are respectively attached with the two clamping claws. The transmission centering clamping device with the rotation axes overcomes the defects that centering claming for a work pieces is difficult to achieve or clamping is not firm, and improves machining efficiency.

Description

technical field [0001] The invention relates to the technical field of centering and clamping devices, in particular to an axis-rotating transmission centering and clamping device. Background technique [0002] At present, the centering clamping device is widely used in mechanical processing. The clamping device is a mechanism that enables the positioned workpiece to be reliably fixed on the positioning element during the entire processing process without changing its position. When clamping the workpiece, it is not allowed to damage the positioning of the workpiece, and there should be enough rigidity to ensure the necessary clamping force, but it should not damage the processed surface of the workpiece or deform the workpiece, so as to ensure the processing accuracy. Since the outer surface of most workpieces needs to be processed, in order to facilitate the processing of the workpiece by the machine tool, the current clamping device has a complicated structure and is ...
