Abstract
The utility model discloses a special tool for assembling and disassembling a connecting pin of a suspension arm and a rotary table, comprising two clamping boards, wherein the two clamping boards are fixedly connected through a pulling post, a guiding sleeve is fixedly mounted in the middle of one of the clamping boards, two long slot holes are symmetrically arranged in the two sides of the excircle of the guiding sleeve along the axis, a nut is mounted on the excircle thread part of the guiding sleeve, a handle is fixedly mounted on the excircle of the nut, and pressing levers are arranged in the long slot holes. The special tool for assembling and disassembling the connecting pin of the suspension arm and the rotary table has the advantages that the labor intensity is lower, the working efficiency is higher, and the assembly quality is better.
Description
Technical field
The utility model relates to a kind of dismounting hinge pin and assembly tool, relates in particular to the turntable of crane and the Assembly And Disassembly specific purpose tool of suspension arm connecting pin, belongs to the specific purpose tool technical field.
Background technology
At present, in some mechanical assembly techniques, especially in the assembling process of the turntable of crane and suspension arm connecting pin, owing to there is no the special specialist tools that is used for the equipment connecting pin, connecting pin is generally that the method that adopts hand hammer or copper rod to force to knock is installed, not only there is the larger defective of labour intensity in the method for this assembling, simultaneously, due to owing to easily the end of bearing pin being knocked distortion, become curved, so, also there is the relatively poor defective of assembly quality, and may causes other mass defect thus.
Summary of the invention
The purpose of this utility model is: for the turntable of existing crane and connecting pin existing defects in assembling process of arm, the utility model provides a kind of assembling turntable and suspension arm connecting pin Assembly And Disassembly specific purpose tool of being specifically designed to, and overcomes existing defects in prior art.
the technical scheme that the above-mentioned purpose that realizes the utility model adopts is: described a kind of turntable and suspension arm connecting pin Assembly And Disassembly specific purpose tool, it is by clamping plate, stay column, pilot sleeve, press thick stick, handle, nut forms, it is characterized in that: be connected and fixed with stay column between two clamping plate, the middle part of clamping plate is vertically installed and is fixed a pilot sleeve therein, the centre of described pilot sleeve is clear opening, be shaped with external screw thread on the cylindrical of described pilot sleeve, on the cylindrical of described pilot sleeve, both sides are shaped with two long slot bores symmetrically along axis direction, cylindrical threaded portion at fairlead is equipped with nut, be mounted with handle on the cylindrical of nut, be provided with the pressure thick stick in long slot bore.
The course of work of the present utility model is: by two clamping plate and stay column, the utility model is clamped on workpiece to be assembled, and the axis of pilot sleeve and the pin shaft hole on workpiece are aligned, at this moment, bearing pin is packed into from the endoporus of pilot sleeve, the nut of screwing on simultaneously, and will press thick stick to be arranged in the end and the long slot bore between nut of bearing pin, turn gradually nut and push the pressure thick stick, so, press thick stick just to promote bearing pin and be installed in pin shaft hole.
Beneficial effect: by structure principle chart of the present utility model operation principle can find out, the utility model is due to after adopting said method, so the utility model has advantages of that not only labour intensity is lower, efficiency is higher, simultaneously, also has assembly quality advantage preferably.
