Abstract
The utility model discloses a convenient omnipotent pin puller, belonging to the field of mechanical processing devices. The utility model comprises a bolt part, a nut part and a support part; the bolt part a comprises an upper end and a lower end, the lower end is a hollow column with a T-shaped groove, the upper end is a bolt, and the upper end and the lower end are welded together; the bolt part b comprises a bolt and a small iron pole, the size of the bolt is the same with the inner hole of step pins, and the bolt is welded with the small iron pole; the support part is made of a cylinder-shaped metal. The utility model has a simple structure, convenient fabrication and easy operation; the utility model can facilitate the replacement of parts with different specifications and sizes; and step pins can be taken out conveniently.
Description
Technical field
The utility model belongs to the machining equipment field, specially refers to the omnipotent finger device of the quick formula that uses in process for the small processing part.
Background technology
On the machining streamline, on jig plate with the step locking bit, when taking out pin the workpiece on being fixed on jig plate, need certain specific purpose tool, because the step pin plays the positioning action between processing work and the jig plate, workpiece is subjected to bigger clamping force man-hour usually adding, to cause pin that certain variation takes place, at the write off period of the day from 11 p.m. to 1 a.m, suffered resistance is bigger, and the instrument of getting the step pin in the past is one on the screw of corresponding step pin inner hole thread size, to one of interior six side and a pair of tongs that should screw, with interior six sides screw is screwed into the endoporus of step pin during operation, firmly pin is extracted with the pliers pinching screw again, firmly bigger usually, pull up gruelling, very time-consuming again, and easily make pin become curved in the process of pulling out, scrap, be sought after this operation operation is improved for this reason, the instrument of pulling pin that designs wide adaptability efficiently and be convenient to operate substitutes existing instrument and operates.
Summary of the invention
The utility model technical issues that need to address are in the operation at the existing step pin of choosing, its operation tool is wasted time and energy, easily make many weak points such as pin distortion, for overcoming these deficiencies, redesign a kind of easy to operate omnipotent pin removal of quick formula simple in structure, in order to reach this purpose, realize by the following technical solutions, the omnipotent pin removal of a kind of quick formula, comprise screw division, nut portions and support portion, it is characterized in that, screw division a be by a hollow cylinder that has T font groove as the lower end, be welded with one section screw of upper end; Screw division b is welded with step pin endoporus screw of the same size and one section little iron prop by one; The support portion is made by a cylindrical section shape metal.Between the optional M3-M24 of described screw division a upper end screw diameter range.The diameter range of described screw division b is chosen as between the M3-M24.The beneficial effects of the utility model are that this pin removal is simple in structure, and is easy to make, is convenient to operation, and the replacement of being convenient to the different specification size parts, can take out the step pin efficiently and easily.
Description of drawings
Fig. 1 is the schematic diagram of this pin removal operating process.
Fig. 2 a is a screw division a structural representation in this pin removal.
Fig. 2 b is a screw division b structural representation in this pin removal.
