A long-lived leaf surface treatment device

Abstract

The invention discloses a long-life blade surface treatment device, which includes a base, a workbench, a blade body, a fixing mechanism, a cooling mechanism and a recovery mechanism. The fixing mechanism is located at the bottom of the workbench, and the fixing mechanism includes an air pump. The output shaft of the air pump is fixedly connected with a connecting pipe, the top of the connecting pipe is fixedly connected with a cavity plate, and the inside of the workbench is provided with an air suction groove; through the designed air pump, connecting pipe, cavity plate and The air extraction groove can use the principle of air pressure difference to fix the blade body, and at the same time, through the first set of rods, connecting plates and guide rods, the top of the partial air extraction groove can be covered, so that blade bodies of different sizes can be fixed. It is fixed, and at the same time, it is convenient to limit the position of the connecting plate by providing a clamping groove, a first fixed block, a fixed plate and a clamping column, thereby increasing the stability of the device and solving the problem of a single structure of the fixing method and a cumbersome fixing process .

Description

technical field [0001] The invention belongs to the technical field of vane pumps, and in particular relates to a long-life vane surface treatment device. Background technique [0002] The pin-type vane pump is a pump in which the blades in the rotor groove are in contact with the pump casing, and the sucked liquid is pressed from the oil inlet side to the oil discharge side. In the single-acting pin-type vane pump, the blades are embedded in the groove. It can slide freely. When the rotation occurs, the blades are thrown onto the pump casing under centrifugal action. The vane pump is a positive displacement pump. When the two adjacent blades move to the bottom, the closed volume with the pump casing and the rotor is the smallest, and when it is on the top, the volume closed is the largest. , when the rotor rotates clockwise, the process from the bottom to the top of the adjacent two blades is the process of volume increase, so oil absorption, from the top to the bottom is t...

Problems solved by technology

[0004] The purpose of the present invention is to provide a surface treatment device for long-lived blades to solve the above-mentioned problems in the background technology. At the same time, when the surface treatment of the blade is carried out, on the one hand, the continuous contact between the tool and the workpiece will generate high temperature, thereby reducing the work efficiency and working time, and at the same time, more waste will be generated, which will be adsorbed on the blade blank. The outer surface affects the machining accuracy of the blade. In addition, these waste chips are difficult to collect due to their small volume.
