Automatic centering and clamping device for pipes

Abstract

An automatic centering and clamping device for pipes is provided with a base 13, wherein a right screw rod 5 and a left screw rod 10 are arranged in the base 13, and a right rotation slide base 6 is arranged in a T-shaped groove, located above the right screw rod 5, of the base 13; when a hydraulic oil motor 1 works, a pinion drives a gearwheel to do rotation motion, then the left screw rod 10 and the right screw rod 5 rotate synchronously, a left rotation slide base and the right rotation slide base are driven to move inwards or outwards simultaneously, and therefore a V-shaped clamping jaw 7 automatically clamps or releases the pipes. By arranging the clamping jaw to be of the V shape, the pipes can be automatically centered in the clamped process and can be clamped more firmly. The hydraulic oil motor drives the pinion and the gearwheel to rotate for driving the screw rods to rotate, and therefore the left rotation slide base and the right rotation slide base move outwards after moving inwards simultaneously for clamping or releasing the pipes. The automatic centering and clamping device is simple in structure, good in centering effect, large in clamping force and high in clamping efficiency.

Description

technical field [0001] The invention relates to a clamping device, in particular to an automatic centering clamping device for pipe fittings. Background technique [0002] Pipe fittings are often used in petroleum engineering. Pipe fittings can be used for the production of artificial well bottoms and oil transportation. However, pipe fittings often encounter inaccurate positioning during processing, especially when processing internal blind holes. , Inaccurate positioning may lead to the scrapping of the entire artificial bottom hole pipe, increasing the cost of oil well operations. For the clamping of pipe parts, the common method is to use flat-nose pliers, which have no automatic centering function, and the pipe fittings are not easy to be tightened and the clamping efficiency is low. There is an urgent need for an automatic tightening device that can automatically center the pipe fittings to meet the requirements of the pipe fittings. processing needs. Contents of th...
