Clamping device used for petroleum mechanical workpiece, and clamping method of clamping device

Abstract

The invention discloses a clamping device used for a petroleum mechanical workpiece, and a clamping method of the clamping device. The clamping device comprises a bottom plate, wherein the middle of the upper surface of the bottom plate is symmetrically fixedly connected with two supporting plates; the adjacent sides of the two supporting plates are independently provided with a first sliding chute; the inner side walls of the two first sliding chutes are independently in sliding connection with a first sliding block; the adjacent sides of the two first sliding blocks are independently fixedlyconnected with a first electric push rod through a screw; and the outer ends of the two first electric push rods are independently fixedly connected with a first fixing plate. When the clamping device is used, certain heavy petroleum mechanical workpieces can be conveniently clamped and fixed, the sizes of the petroleum mechanical workpieces are adapted, in addition, through the reverse thrust force of first springs, fixing for the petroleum mechanical workpieces can be reinforced, the positions of the two first fixing plates are fixed, and therefore, the petroleum mechanical workpieces can be more stably clamped. The clamping device has a good clamping effect and a wide use range, and meanwhile, the clamping device is simply operated, is conveniently used and saves the labor intensity ofworkers.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery workpiece clamping, in particular to a clamping device and a clamping method for petroleum machinery workpieces. Background technique [0002] Petroleum, one of the main objects of geological exploration, is a viscous, dark brown liquid known as the "blood of industry." There are oil reserves in parts of the upper crust. The main component is a mixture of various alkanes, naphthenes and aromatic hydrocarbons. Petroleum is mainly used as fuel oil, gasoline and some chemical industry products. With the continuous development of the times, more and more car users, the consumption of oil is also increasing, and the machinery for oil exploration and mining is also increasing. When carrying out exploration and mining operations, some workpieces need to be clamped for replacement and use. [0003] The existing clamping device for petroleum mechanical workpieces is inconvenient to move the ...

Problems solved by technology

[0003] The existing clamping device for petroleum mechanical workpieces is inconvenient to move the petroleum mechanical workpieces to the clamping device for clamping and fixing when clamping some heavier petroleum mechanical workpieces during the clamping process, which increases the The labor intensity of the staff, and at the same time, when the petroleum machinery workpiece is clamped, most of the petroleum machinery workpieces are of irregular shape, resulting in a small contact area with the clamping device when the petroleum machinery workpiece is clamped, and the clamping and fixing of the petroleum machinery workpiece is not stable. Petroleum machinery workpieces are easy to loose when clamping, which affects oil exploration and mining operations. The existing clamping devices are special-shaped clamping mechanisms designed for special workpiece contour structures, but they are clamped for various sizes and types of equipment The robustness of the operation is poor, and it is necessary to design and reserve a variety of clamping heads, so that the cost increases and the additional time for repeated assembly is required. Therefore, a clamping device and its clamping device for petroleum machinery workpieces are proposed. method
