Abstract
The utility model relates to a pneumatic pin pulling head which is used for dismounting the upper opening pin of an operating rod of the right cover of an engine. The utility model is mainly composed of a connecting sleeve 1, a connecting pin 2, a pin pulling rod 3 and a pin pulling hook 4, wherein one end of the pin pulling rod 3 is provided with the pin pulling hook 4 in a radial direction; the other end of the pin pulling rod 3, which extends into the connecting sleeve 1, is connected with the connecting sleeve 1 by the connecting pin 2; the connecting pin 2 passes through the connecting sleeve 1 which is provided with external threads. The utility model is integrally installed on an air cylinder body of a dismounting machine, the pin pulling rod is driven to upwards move by an air cylinder through stepping an air valve switch of the air cylinder body of the dismounting machine; thereby, the pin pulling hook is driven to upwards move; the opening pin of the operating rod, which is hooked on the pin pulling hook, is immediately pulled out; the whole process of pulling the pin can be rapidly finished. The utility model has the advantages of high work efficiency, convenient and simple operation, and labor saving; the utility model can be suitable for dismounting in bulk.
Description
One, technical field:
The utility model relates to a kind of provision for disengagement, relates in particular to a kind of pneumatic head of pulling pin that is used to dismantle the right cover controlled bar cottering of engine.
Two, background technology:
At present, in the product sampling observation, product is if problem, need find out problem or all do over again, this just needs a large amount of dismantlement works, and the split pin on the tradition dismounting workpiece is to use cutting pliers to carry out hand disassembly, with the jaw clamping split pin of cutting pliers, is holding the cutting pliers handle outwards to pull out with strength, because the cutting pliers arm is short, again can not the fixed position in when dismounting, therefore, dismantle very time-consuming, effort, removal efficiency is low, particularly dismounting is the right split pin of covering on the interior control stick of engine of spill, uses pliers manual operations, inefficiency by the workman, dismounting is extremely inconvenient, usually being that pliers is bad puts in place, and perhaps artificial bad exerting oneself can not adapt to dismantlement work in enormous quantities at all.
Three, summary of the invention:
The purpose of this utility model provides a kind of removal efficiency height, simple to operate, the pneumatic head of pulling pin that can adapt to dismounting in enormous quantities.
Concrete scheme of the present utility model is: the end at the bar of pulling pin radially is provided with the hook of pulling pin, and the other end of the bar of pulling pin stretches in the adapter sleeve, is linked to each other with adapter sleeve by the connecting pin that passes it, and described connection is with external screw thread.
The described bar of pulling pin of this programme can stretch in the right lid of the engine that is spill by lowering or hoisting gear, and its hook of pulling pin can pass the split pin on the control stick, when lowering or hoisting gear rises, rapidly the split pin on the control stick in the right lid of engine is extracted.This programme with adapter sleeve be provided with externally threaded purpose be convenient to the form that is threaded with the utility model integral installation on lowering or hoisting gear, drive the bar of pulling pin by moving up and down of lowering or hoisting gear and move up and down, thereby finish the dismantlement work of split pin.
The utility model not only can be finished the dismounting to the split pin of the control stick in the right lid of engine, and can realize the dismantlement work of the split pin on the various workpiece.
The utility model has the advantages that: high efficiency, adapt to dismounting in enormous quantities, convenient and simple for operation, laborsaving, and save the labour.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is that the utility model is installed in the situation on the lowering or hoisting gear, and described lowering or hoisting gear is a kind of cylinder type lifting device, and the utility model has been formed the air-cylinder type demountor in conjunction with the cylinder type lifting device.
Five, the specific embodiment:
From Fig. 1, Fig. 2 as can be known: the utility model mainly is made up of adapter sleeve 1, connecting pin 2, the bar 3 of pulling pin, the hook 4 of pulling pin, wherein the end at the bar 3 of pulling pin radially is provided with the hook 4 of pulling pin, the other end of bar 3 of pulling pin stretches in the adapter sleeve 1, linked to each other with adapter sleeve 1 by the connecting pin 2 that passes it, described adapter sleeve 1 has external screw thread.
See Fig. 1, Fig. 2 as can be known: the hook 4 of pulling pin is overall structure with the bar 3 of pulling pin, and the hook 4 of pulling pin is sharp cone distal, and its axial line is perpendicular to the central axis of the bar 3 of pulling pin.The hook 4 of pulling pin can be strengthened for the single piece structure makes the utility model rigidity and intensity with the bar 3 of pulling pin, and the hook 4 of pulling pin is sharp cone distal and conveniently stretches in the split pin on the cover controlled bar in the engine right side.The hook 4 of pulling pin can be made other structure, and is all right as long as the tip of the hook 4 of pulling pin can be stretched in the split pin.
See that Fig. 1 as can be known: adapter sleeve 1 is tubular construction, and its center through hole is stepped, and the large aperture end outer wall of adapter sleeve 1 has external screw thread; The bar 3 of pulling pin stretches into from the small-bore end of adapter sleeve 1, and its afterbody is positioned at the macropore of connecting pin 2.The large aperture end outer wall of adapter sleeve 1 has external screw thread, helps adapter sleeve 1 is installed on the cylinder block of demountor, drives the hook 4 of pulling pin by cylinder and moves up and down the dismantlement work of finishing control stick split pin in the right lid of engine.
See Fig. 3, the right cover gab of engine that will be spill makes progress, at this moment, control stick in the right lid exposes and up, when the bar 3 of pulling pin is positioned at low spot, the aligning of the split pin on the control stick is packed in the hook of pulling pin, left foot is stepped on air valve switch then, cylinder drives the bar 3 of pulling pin and moves up, and the control stick split pin that is hooked on the hook of pulling pin is pulled out immediately, and the whole process of pulling pin is finished.
The utility model can be regulated depth size to cylinder according to different types of pin, lid in conjunction with the air-cylinder type demountor, and it is mainly used in the dismounting of doing over again of workpiece in enormous quantities.
