Abstract
The invention relates to a pin shaft assembling and disassembling tool, wherein a guiding pipe is vertically and fixedly mounted on one side edge of a U-shaped clamping head; two long groove holes are symmetrically formed in the outer circle of the guiding pipe in the direction of an axis line; an outer screw thread is arranged on the outer circle of the guiding pipe; a nut is mounted on the outer screw thread of the guiding pipe; a fixing handle is mounted on the outer circle of a nut; and pressing lead screws are arranged in the long groove holes of the guiding pipe. The pin shaft assembling and disassembling tool has the advantages of simple structure, convenience in use and good assembling quality of a workpiece.
Description
Technical field
The present invention relates to a kind of bearing pin Assembly And Disassembly instrument, relate in particular to the Assembly And Disassembly instrument that is connected bearing pin between a kind of engineering machinery arm and the turntable, belong to the hardware ﹠ tools technical field.
Background technology
At present, many plant equipment are when the loading and unloading bearing pin, because without special instrument, the general method that adopts hammer or copper rod to knock reaches the Assembly And Disassembly purpose of bearing pin, like this Assembly And Disassembly that wherein is connected bearing pin between the arm of engineering machinery and turntable is exactly, so, not only waste time and energy, and assembling is second-rate.
Summary of the invention
The object of the invention is to: for the existing defects of Assembly And Disassembly that is connected bearing pin between the arm of existing bearing pin assembling, especially engineering machinery and the turntable, the invention provides a kind of novel bearing pin Assembly And Disassembly instrument, be connected the existing defects of Assembly And Disassembly of bearing pin between the arm that overcomes existing engineering machinery and the turntable.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: described a kind of bearing pin Assembly And Disassembly instrument, comprise U-shaped clamping joint, guide pipe, pressure thick stick, handle, nut, side at U-shaped clamping joint vertically is mounted with guide pipe, be shaped with symmetrically two long slot bores along axis direction on the cylindrical of described guide pipe, cylindrical at guide pipe is shaped with external screw thread, external screw thread setting at guide pipe is equipped with nut, cylindrical at nut installs and fixes handle, is provided with the pressure thick stick in the long slot bore of guide pipe.
The course of work of the present invention is such: workpiece to be installed is fastened between the U-shaped clamping joint, and the diameter that makes the axis of guide pipe and workpiece upper pin hole is to aligning, the end of bearing pin from guide pipe penetrated, the head of pressing thick stick to be close to bearing pin is installed in the nut of then screwing in the long slot bore, along with nut constantly pushes the pressure thick stick, press thick stick just constantly bearing pin to be pressed in the hole of workpiece.
Beneficial effect: can be found out that by structure principle chart of the present invention the present invention not only has advantage simple in structure, easy to use, simultaneously, also have preferably advantage of workpiece assembly quality.
