Abstract
The utility model provides a coupling flange pin disassembling tool. The utility model is characterized in that the utility model comprises a top fastening bolt, wherein, the inside of threads of the top fastening bolt is provided with an inner screw nut, and the outside of the threads is provided with a regulating screw cap. When a flange pin is disassembled, a pressure plate is pressed and leaned against the end surface of the flange pin, the regulating screw cap at the other end is supported on a motor casing, and then, the screw cap is rotated by a spanner so that the screw cap moves in an axial direction. In this way, the flange pin can be extruded through outwards pressing the flange pin by the pressure plate. Disassembly which is fast, time saving and labour saving can be finished by several minutes, and work efficiency is enhanced.
Description
Technical field
The utility model relates to a kind of extracting tool, specifically a kind of specific purpose tool of dismantling shaft coupling flange pin.
Background technology
Existing shaft coupling has various versions, and most of shaft couplings rely on flange pin transferring power, and flange pin and axis hole generally adopt interference fits or interference fit, and both have certain tightness.But when needing maintain and replace shaft coupling flexible rubber ring, because shaft coupling and actuating unit (as motor) housing distance are very close, during with the blue pin of the outside play of hand hammer, blocked by electric machine casing, stroke is too short, can't get the flange pin, dismantle a flange pin and need 3-4 hour, also usually flange pin screw top place is flattened, cause discardedly, dismounting is wasted time and energy.How overcoming above-mentioned defective as early as possible, then is urgent problem.
Summary of the invention
The utility model is to solve the problem that dismounting flange pin that prior art exists is wasted time and energy.
In order to reach the purpose that solves the problems of the technologies described above, the technical solution of the utility model is: a kind of shaft coupling flange pin extracting tool, and it is characterized in that: it comprises a top fastening bolt, top fastening bolt screw thread installed inside has interior nut; Its outside is equipped with the adjusting nut.
In this usefulness is novel, also have following technical characterictic: described top fastening bolt head has a platen greater than the diameter of bolt.
In this usefulness is novel, also have following technical characterictic: platen end face middle part has a locating hole.
The utility model compared with prior art has the following advantages and good effect: when 1, dismantling the flange pin, platen is pressed against flange pin end face, the adjusting nut of the other end withstands on the electric machine casing, use the spanner rotating screw cap then, make it to move axially, so just can be by the blue pin of platen eccentropiesis, the flange pin is extruded, it is time saving and energy saving fast to dismantle, and only needs just detachably finish in several minutes, has improved operating efficiency greatly.When 2, dismantling, adopt the blue pin of platen platen press, flange pin end can not flattened, avoided unnecessary damage.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is a front view of the present utility model;
Fig. 2 is a profile of the present utility model.
1, flange pin extracting tool; 2, platen; 3, top fastening bolt; 4, interior nut; 5, regulate nut; 6, locating hole.
Referring to Fig. 1 and Fig. 2, flange pin extracting tool of the present utility model is used mark 1 chief representative.Top fastening bolt 3 heads are diameter platens 2 greater than screw diameter, and there is a locating hole 6 at middle part, platen 2 outer faces.Top fastening bolt 3 inboards are nuts 4 in, and it and top fastening bolt 3 are fixed as one, and bolt 3 can not be rotated, and are equipped with one in interior nut 4 outsides versatilely and regulate nut 5.
In the time will dismantling the flange pin, the locating hole on the platen 26 is inserted flange pin end, rotate adjusting nut 5 then and make on its electric machine casing that leans against the other end, rotate adjusting nut 5 with spanner again it is outwards moved, so just the flange pin can be ejected.Certainly, the utility model is not limited to only dismantle the flange pin, and all similar structures that belongs to all can use.
Above-mentioned is not to restriction of the present utility model for example, and those of ordinary skill in essential scope of the present utility model, also can be made some variations, improvement, interpolation or replacement, also should belong to the utility model protection domain.
