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 rotation formula 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 plug 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, present work support is comparatively inconvenient to the adjusting of plug axiality, and because the support easily worn part pushes up comparatively complicacy of wheel dismounting step as follows; The difficulty that causes maintenance and change, clamping of workpiece is also comparatively difficult.
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, convenient adjusting, plug for ease of maintenaince to process special-purpose rotation formula centre frame.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of plug is processed special-purpose rotation formula centre frame, comprises main frame, two following top wheel mechanisms and a last top wheel mechanism of entad being provided with, and said main frame comprises base, side stand and upper bracket; Be symmetrically installed with installing rack under the said base; Said side stand symmetry is packed in the base two ends, it is characterized in that: upper bracket one end is connected with the upper end of a side stand through swing shaft, upper bracket and the outer coaxial axle sleeve that is with of the swing shaft between the side stand; The other end of upper bracket is connected with the upper end of opposite side stand through fastening bolt; This fastening bolt hinge is contained in the bolt indentation of making the side stand upper end, and the upper bracket end that fastening bolt is corresponding is shaped on the bolt groove, and said upper bracket middle part installs top wheel mechanism on; Should go up the rotation of wheel mechanism lower end, top and install roller; Should go up wheel mechanism upper end, top the adjusting bolt is installed, a horizontal guide rail is installed on the base in main frame, two symmetrical slide holders are slidingly installed on this horizontal guide rail; These two slide holders are installed in two horizontal screw leads drivings of two side stand bottoms respectively by engagement, on these two slide holders bottom roller is installed respectively.
And, being shaped on support slot on the said slide holder, bottom roller is movably arranged in the corresponding support slot.
The advantage and the good effect of the utility model are:
1, this plug is processed special-purpose rotation formula centre frame and can be regulated two symmetrically arranged top wheel mechanisms down and middle last top wheel mechanism respectively; Can accurately regulate the axiality of plug; Effectively guarantee the axiality of plug in process; Guarantee to produce and carry out smoothly, guaranteed the quality level that plug is electroplated, guarantee product quality.
2, it is simple in structure that this plug is processed special-purpose rotation formula centre frame, and entablature adopts rotation formula structure, need not to adopt crane to move entablature, gets final product direct workpiece loading and unloading plug, and is simple to operate, simplifies production stage, significantly improves production efficiency.
3, this plug is processed the adjusting employing horizontal screw lead driving of top wheel under the special-purpose rotation formula centre frame; Two bottom rollers carry out horizontal level to be regulated, and the wheel shaft of bottom roller is movably arranged in the corresponding support slot, and need not fix; Easy disassembly, for ease of maintenaince and change.
4, simple in structure, the design science of the utility model, accurate positioning; Can effectively guarantee the axiality in the plug processing, simplify the dismounting step of plug workpiece, and be convenient to maintenance; Each parts is easy to adjust, easy, can effectively promote production efficiency and product quality.
