Description
Technical field
The utility model belongs to field of metallurgy, relates to the processing of plug, and especially a kind of plug is processed special-purpose four-wheel centre frame.
Background technology
Plug is one of important tool of producing in seamless steel pipe, need under high temperature, condition of high voltage, carry out work, thereby the technical conditions of its processing and fabricating require very high; The processing of plug need be passed through multiprogrammings such as drill centers, machined into, sanding and polishing, chromium plating, because plug belongs to long axis workpiece, two ends are installed on machine chuck in the workpiece process; Simultaneously, the middle part of workpiece also need be provided with some bracing frames, guarantees the plug axiality; Guarantee machining accuracy, avoid causing product quality problem, particularly add man-hour carrying out turning; Because the radial load that receives is bigger; Common support is difficult to satisfy the axiality requirement of plug, and axiality regulates and comparatively to waste time and energy, and influences production efficiency.
Summary of the invention
The purpose of the utility model is to overcome the weak point of prior art, provides a kind of design science, simple in structure, accurate positioning, plug that support force is big to process special-purpose centre frame.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of plug is processed special-purpose four-wheel centre frame; Four top wheel mechanisms that comprise four jiaos of pedestal, vertical quadra and this vertical quadras; Vertical quadra is coaxial to be packed on the pedestal, it is characterized in that: said vertical quadra is made up of the top frame and the bottom frame of upper and lower symmetry, and said vertical quadra is provided with a top wheel mechanism to the frame center inclination respectively for four jiaos; This top wheel mechanism comprises top hub cap, leading screw, the rolling wheel support that has pair of nut, roller, lock(ing) bolt and pilot pin; Vertical quadra is shaped on respectively to frame center inclination top hub cap for four jiaos, and the coaxial engagement of said leading screw is installed in the hub cap of top, and rolling wheel support one end is processed internal thread and the engagement of said leading screw; The rolling wheel support other end is installed roller; Through rotating threaded shaft driving rolls support and drive roller and carry out position adjustments, said rolling wheel support outside mean line system has stopper slot, and top hub cap and stopper slot relative position install pilot pin; This pilot pin slides along the rolling wheel support stopper slot and limits the position of final conclusion mechanism, on the hub cap of top, lock(ing) bolt is installed.
And; Cut with scissors respectively in the bolt slot that make in the outside, frame two ends, bottom and adorn a fastening bolt; The frame outside, top correspondence is shaped on mounting groove, and frame two ends, top are connected with the bottom frame through said fastening bolt respectively, and said top frame and bottom frame bilateral symmetry are shaped on hole for hoist.
And said pedestal bilateral symmetry is shaped on four installing holes.
The advantage and the good effect of the utility model are:
1, this plug is processed special-purpose four-wheel centre frame and can be regulated four symmetrically arranged top wheel mechanisms respectively; Axiality simple in structure, easy to adjust, as can accurately to regulate plug, support force is big; Can effectively guarantee the axiality of plug in process, guarantee to produce and carry out smoothly.
2, this plug four symmetrically arranged top wheel mechanisms processing special-purpose four-wheel centre frame are equipped with location and locking device, and it is more accurate locate, and has bigger support force, has guaranteed the quality level of plug plating,
3, simple in structure, the design science of the utility model, accurate positioning significantly improve the support force of centre frame, can effectively guarantee the axiality of plug work in-process, and easy to adjust, easy, have promoted production efficiency and product quality effectively.
Description of drawings
