Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
Fig. 1-2 are schematic structural views of a mechanical assembling and disassembling tool according to the present invention. The mechanical assembling and disassembling tool comprises a fixed support 2, a movable support 7, a jack bolt 1, an outer side pull rod 3, an inner side pull rod 4 and a fulcrum crow bar 5;
the jack bolt 1 comprises a head part, a screw rod part and a thread part, the screw rod part is not provided with threads, the fixed support 2 is sleeved on the screw rod part of the jack bolt 1 in a penetrating way, and the movable support 7 is sleeved on the thread part of the jack bolt 1 in a penetrating way through threads;
the fulcrum crowbar 5 is provided with a far-end pin hole, a near-end pin hole and a working end; the near-end pin hole is located between the far-end pin hole and the working end, and the working end is wedge-shaped.
One end of the outer side pull rod 3 is hinged to the fixed support 2, and the other end of the outer side pull rod 3 is hinged to the fulcrum crowbar 5 through the far-end pin hole;
one end of the inner side pull rod 4 is hinged to the movable support 7, and the other end of the inner side pull rod 4 is hinged to the fulcrum crowbar 5 through the near-end pin hole;
the outer side pull rod 3, the inner side pull rod 4 and the fulcrum crow bar 5 are 2 groups.
The head of the screw is a dodecagonal head.
As shown in fig. 3, when the jack bolt 1 is rotated clockwise, the thread part drives the movable support 7 to move upwards, the fixed support 2 and the jack bolt are kept relatively static, so that the upward movement of the movable support 7 pulls the near-end pin hole of the fulcrum crowbar 5 to move upwards through the inner side pull rod 4, the outer side pull rod 3 pushes the far-end pin hole end of the fulcrum crowbar 5 to move downwards, and thus the lever action taking the bottom of the fulcrum crowbar or the near-end pin hole of the fulcrum crowbar 5 as a fulcrum is realized, at the moment, the working end part of the fulcrum crowbar moves upwards on one side, and moves towards the jack bolt 1 on the other side, so that the extrusion and drawing work of the disassembled and assembled part is realized; from this the utility model discloses a mechanical assembly extracting tool collection lever principle draws, and the strength output is accomplished in extruded principle combination, and the strength output effect of doubling is showing. The structure is simple, the requirement on the processing technology is not high, and the production is facilitated; the operation is simple, the stroke is large, only the jack bolt 1 needs to be rotated, repeated adjustment is not needed in the primary dismounting process, and the time is saved; the event the utility model discloses a mechanical assembly extracting tool has greatly simplified the dismantlement work that the interference was equipped.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
