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

Embodiment Construction

[0007] As shown in Figure 1, the top pressure centering clamping device of the present invention includes a base 1, a positioning pin 2, two jaws 3, and a frame 6. The base 1 has a through hole in the axial direction, and the positioning pin 2 is installed In the through hole, the two sides of the upper top of the base 1 and the two jaws 3 are respectively hinged through the connecting block 4, the two jaws 3 are hinged with the frame 6, and the positioning pin 2 is inserted into the position of the through hole of the base 1 A nut is installed, and a return spring 5 is arranged between the nut and the base 1 . Put the two jaws 3 into the positioning hole of the workpiece 7 to be positioned, press the positioning pin 2, the return spring compresses and pushes the base 1 to move upward, and the two jaws 3 are respectively hinged on the base through the two connecting blocks 4 On both sides of the upper top of the seat 1, the two jaws 3 open outwards to clamp the workpiece cent...

Abstract

The invention discloses an ejector type centering and clamping device, and relates to a centering and clamping device. The device comprises a base, a locating pin, two clamping jaws and a machine frame, wherein the base is axially provided with a through hole, the locating pin is installed in the through hole, the base and the two clamping jaws are respectively hinged through connecting blocks, the two clamping jaws are hinged with the machine frame, the locating pin is provided with a nut, and a reset spring is disposed between the nut and the base. The device overcomes the defects that the structure of an existing device is complex, centering and clamping of workpieces are difficult and clamping is not firm, and improves machining efficiency.

Description

technical field [0001] The invention relates to the technical field of centering clamping devices, in particular to a top pressure centering 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 inconvenient to operate...
