Abstract
The utility model discloses a mandrel positioning device, which solves the technical problem of inaccurate mandrel positioning in the conventional equipment. The mandrel positioning device comprises a base (1), a left side plate (2) and a right side plate (3), wherein two guiding support shafts are arranged between the two side plates; a left V-shaped plate and a right V-shaped plate which are provided with two round holes are respectively sleeved on the two guiding support shafts through the two round holes to form a sliding seat (6); a second hydraulic cylinder (13) and an oscillating seat (8) are arranged in the sliding seat (6); the middle of the oscillating seat (8) is sleeved on an upper guiding support shaft (4); one end of the oscillating seat (8) is fixedly connected with the output shaft of the second hydraulic cylinder (13), and a shifting block (11) is arranged at the other end thereof; and the output shaft of a first hydraulic cylinder (7) is fixedly connected with the left V-shaped plate of the sliding seat (6). The mandrel positioning device provides necessary guarantees for smooth and accurate connection between a mandrel and a mandrel trolley when the mandrel is replaced.
Description
Technical field
The invention belongs to the subsidiary engine equipment in the seamless steel tube production, be specifically related to when the milling train side direction is changed push rod, plug, the device that push rod is accurately located, adjusted.
Background technology
In the production process of seamless steel pipe, in order to satisfy the requirement of production technology, need carry out online replacing to instruments such as push rod, plugs, the conventional method that adopts is to use material to collude its dial-out or dials in, perhaps it is sent into equipment through traversing chain, and in the process that push rod is dialled in, be difficult to its accurate location the connecting portion of push rod, plug to be connected smoothly with equipment.Particularly transfer to and be placed on when being rotated cooling on the rotation carrying roller when push rod, since push rod can be vertically in the process of rotation string moving, when dialling in push rod next time,, can not accurately put in place with the position of equipment generation deviation, so just can't be connected, finish rolling with equipment.
Summary of the invention
Ejector pin and mandrel positioning device provided by the invention has solved existing equipment and produced the technical problem that deviation can not accurately put in place when instruments such as push rod, plug being carried out online the replacing.
The present invention overcomes the above problems by following scheme:
Ejector pin and mandrel positioning device, comprise base, the left plate and the right plate that fixedly install respectively at the two ends, the left and right sides of base, be set with the guiding back shaft between described left plate and the right plate respectively and the back shaft that leads down, the left V shaped slab that is provided with two circular holes is set on guiding back shaft and the following guiding back shaft by these two circular holes, the right V shaped slab that is provided with two circular holes also is set on guiding back shaft and the following guiding back shaft by its two circular holes, the oil cylinder seat of the end of a left side V shaped slab and right V shaped slab by second hydraulic jack sliding seat that is composed of a fixed connection, be provided with second hydraulic jack and swing seat between left V shaped slab in this sliding seat and the right V shaped slab, the middle part of swing seat is provided with a circular port, the swing seat is sleeved on the guiding back shaft by this circular port, one end of swing seat and the output shaft of second hydraulic jack are fixed together, the other end of swing seat is set with shifting block, this shifting block is arranged on the below of push rod stern notch, and shifting block is provided with the semi-circular recesses that cooperates with the push rod stern notch; Left plate is provided with first hydraulic jack, and first hydraulic jack is arranged on the guiding back shaft and leads between the back shaft down, and the left V shaped slab of the output shaft of this first hydraulic jack and sliding seat is fixed together.
One end of described swing seat and the output shaft of second hydraulic jack are to be fixed together by bearing pin.
The present invention is simple in structure, and is easy to install, can be to push rod accurate in locating and adjustment, when changing for push rod smoothly and ejector rob trolley providedly be connected the assurance that provides necessary.
