Abstract
The invention discloses a demounting device for a rocker arm shaft of a cylinder head. The demounting device comprises a pneumatic wrench, a positioning bearing plate (4) and a demounting assembly connected with the positioning bearing plate (4) in a clearance fit manner. The demounting assembly comprises a screw (1), a screw rod (2) and a screw rod sleeve (3) which is in threaded connection with the screw rod (2), wherein the screw (1), the screw rod (2) and the screw rod sleeve (3) are arranged in sequence from inside to outside. An inner cavity of the screw rod (2) is an inner through hole matched with the screw (1) in outer diameter. A positioning connecting hole (5) corresponding to an installation seam allowance hole in the face of a cylinder head side cover and a screw through hole (6) allowing the screw (1) to penetrate and corresponding to a threaded hole of the rocker arm shaft are symmetrically formed in the positioning bearing plate (4) in a left-right manner. The demounting device is reasonable and simple in structural design, low in cost, convenient and easy to demount and capable of saving time, labor and manual work, the demounting quality and safety of the rocker arm shaft of the cylinder head are ensured, the repair efficiency is improved, the repair cost is reduced, and the demounting efficiency of the rocker arm shaft of the cylinder head is greatly improved.
Description
Technical field
The present invention relates to technical field of engines, be specifically related to the provision for disengagement of a kind of cylinder head rocker arm shaft.
Background technology
Engine cylinder head rocker arm shaft is connected with cylinder head rocker shaft hole, is substantially all to adopt interference fit to connect, and adopts hammer or impact gun to squeeze into when rocker arm shaft assembles.When certain parts of cylinder head occur that quality problems or wearing and tearing need to change, such as inlet and exhaust valve gas leakage, the situations such as camshaft or rocking arm inordinate wear need to dismantle rocker arm shaft when occurring, prior art gets a double threaded screw, screw rod one end is screwed in rocker shaft hole, the other end penetrates in the circular iron block hole of certain mass, nut is screwed in again in screw tip, the impulse inertia slided on screw rod by using circular iron block and rocker arm shaft is extracted from hole, need two people to coordinate just can complete, a people pins cylinder head, one people carries out slip to circular iron block and impacts.Often dismantle a rocker arm shaft usually to need rocker arm shaft to be extracted through repeat impact, usually fly out due to the inertia of slide block when rocker arm shaft is extracted, slide block likely strikes people and thing simultaneously, produces potential safety hazard.This provision for disengagement, not only time-consuming, effort and dangerous, production efficiency is also low.
Summary of the invention
The object of the invention is the deficiency in order to overcome in existing provision for disengagement technology, there is provided " provision for disengagement of a kind of cylinder head rocker arm shaft ", this apparatus structure is reasonable in design simple, with low cost, convenient disassembly, easily, time saving and energy saving and less manpower, guarantees cylinder head rocking arm dismounting hinge pin quality and safety, improves and reprocesses efficiency, cost is reprocessed in saving, has increased substantially cylinder head rocker arm shaft removal efficiency.
To achieve these goals, the present invention is achieved through the following technical solutions: the provision for disengagement of a kind of cylinder head rocker arm shaft, and main technical scheme is, the disconnect assembly comprising pneumatic impact spanner, locating support plate 4 and be connected with locating support plate 4 matched in clearance.
Described disconnect assembly comprises the screw 1, screw rod 2 and the screw sleeve 3 that is threaded with screw rod 2 that outwards set gradually from inner, and described screw rod 2 inner chamber is the inner via hole suitable with screw 1 external diameter.
Further technical scheme is, on locating support plate 4, left and right is arranged with the screwing through hole 6 corresponding with rocker arm shaft screwed hole installed seam hole corresponding be located by connecting hole 5 and confession screw 1 with cylinder head side cover face and pass.
Further technical scheme is, the lower end of described screw 1 is provided with the external thread section 7 suitable with rocker shaft hole internal thread.
Tool of the present invention has the following advantages:
This apparatus structure is reasonable in design simple, with low cost, convenient disassembly, easily, time saving and energy saving and less manpower, guarantees cylinder head rocker arm shaft dismounting quality and safety, improves and reprocess efficiency, save and reprocess cost, increased substantially cylinder head rocker arm shaft removal efficiency.
Accompanying drawing explanation
Fig. 1 is that assembling of the present invention master looks sectional structure schematic diagram.
In figure, 1, screw 2, screw rod 3, screw sleeve 4, supporting block for location, 5, be located by connecting hole, 6, screwing through hole, 7, external thread section.
Detailed description of the invention
Below by non-limiting example, set forth the present invention further, understand the present invention.
Embodiment
As shown in Figure 1, the provision for disengagement of a kind of cylinder head rocker arm shaft, the disconnect assembly comprising pneumatic impact spanner, locating support plate 4 and be connected with locating support plate 4 matched in clearance.
Described disconnect assembly comprises the screw 1, screw rod 2 and the screw sleeve 3 that is threaded with screw rod 2 that outwards set gradually from inner, and described screw rod 2 inner chamber is the inner via hole suitable with screw 1 external diameter.
On locating support plate 4, left and right is arranged with the screwing through hole 6 corresponding with rocker-arm roller pin male thread hole installed seam hole corresponding be located by connecting hole 5 and confession screw 1 with cylinder head side cover face and pass.
The lower end of described screw 1 is provided with the external thread section 7 suitable with rocker shaft hole internal thread.
Concrete disassembling section method:
1, first the locating support plate 4 of provision for disengagement is arranged on cylinder head side cover face to be located by connecting on hole 5, and screwing through hole 6 is aimed at rocker shaft hole;
2, screw sleeve 3 and screw rod 2 screwed assembly are arranged on the screwing through hole 6 on locating support plate 4;
3, screw 1 is passed screw rod 2 inner via hole and screws in rocker shaft hole, operator's left-handed screw sleeve 3, right hand pneumatic impact spanner is inserted in the reversion of screw rod 2 turret head and produces reverse torque and extracted by rocker arm shaft.
In sum, reasonable in design of the present invention is simple, with low cost, convenient disassembly, easily, time saving and energy saving and less manpower, guarantees cylinder head rocker arm shaft dismounting quality and safety, improves and reprocess efficiency, cost is reprocessed in saving, has increased substantially cylinder head rocker arm shaft removal efficiency.
