Description

A kind of valve-spring tool
Technical field
The utility model relates to engine maintenance field of tool, in particular to a kind of valve-spring tool.
Background technology
Valve spring in automobile engine cylinder head assembly is by being stuck in valve spring upper seat on valve stem and locker is compressed, and when dismantling valve spring, needing first compression valve spring, could take out locker thus pull down valve spring.Because the elastic force of valve spring is very large, general all need to use specific purpose tool or under cylinder cap is placed on forcing press, take off locker after valve spring being compressed with forcing press to dismantle again, in existing specific purpose tool, what have is poor to the adaptability of engine cylinder cover structure, in practical operation, the clamping trouble of this instrument is time-consuming, in disassembly process, instrument is also easily shifted, and needs repeatedly to adjust; And forcing press is heavy greatly, is not easy to carry, needs to carry back and forth cylinder cap, waste time and energy, reduce efficiency.
Utility model content
The purpose of this utility model is that providing a kind of installs convenient, firm valve-spring tool, to solve the problem.
For realizing the utility model object, the technical scheme of employing is: a kind of valve-spring tool, comprises depression bar, pull bar, connecting rod, bracing frame, two pressing plates; The two ends of depression bar are respectively exert pressure end and positioning end; One end of pull bar and the positioning end of depression bar hinged, the other end and the connecting rod of pull bar removably connect; One end away from pull bar of connecting rod is provided with the external screw thread matched with cylinder cap upper bolt hole; Bracing frame to be arranged on depression bar and hinged with depression bar, and the end away from depression bar of bracing frame is inverted U-shaped, and two straight-arms of inverted U-shaped bracing frame connect two pressing plates respectively, and the spacing between two pressing plates is greater than the full-size of locker; Depression bar offers the multiple circular holes along depression bar axially-aligned, bracing frame is connected by pin with circular hole.
Further, described connecting rod pull bar link is provided with pin, pull bar correspondence offers the pin-and-hole mated with pin.
Further, described pressing plate is connected with bracing frame bolt.
Further, the multiple circular holes on described depression bar are interconnected, and the end of exerting pressure of depression bar is provided with handle.
The beneficial effects of the utility model are, by the bolt hole internal fixtion screwing into cylinder cap of connecting rod, pull bar lower end is connected with connecting rod, the pressing plate of bracing frame lower end is placed on valve spring upper seat and firmly descends moulded rod and bracing frame, valve spring is compressed, can load onto or take off the locker above valve spring and then take out valve spring, and the distance between valve spring upper seat and connecting rod can regulate the adjustment that arranges by pressing plate by the circular hole that depression bar is arranged as required, the valve spring dismounting of various model engine can be applicable to, convenient and swift, highly versatile, meet the use needs of auto repair personnel.
Accompanying drawing explanation
Fig. 1 is the structural representation of the valve-spring tool that the utility model provides.
Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described in further detail below by specific embodiment.
Fig. 1 shows the valve-spring tool that the utility model provides, and comprises depression bar 1, pull bar 2, connecting rod 3, bracing frame 4, two pressing plates 5; The two ends of depression bar 1 are respectively exert pressure end and positioning end; One end of pull bar 2 and the positioning end of depression bar 1 hinged, the other end and the connecting rod 3 of pull bar 2 removably connect; One end away from pull bar 2 of connecting rod 3 is provided with the external screw thread 31 matched with cylinder cap upper bolt hole; Bracing frame 4 to be arranged on depression bar 1 and hinged with depression bar 1, and the end away from depression bar 1 of bracing frame 4 is inverted U-shaped, and two straight-arms of inverted U-shaped bracing frame 4 spacing connected respectively between two pressing plates, 5, two pressing plates 5 is greater than the full-size of locker; Depression bar 1 offers the multiple circular holes 11 along depression bar 1 axially-aligned, bracing frame 4 is connected by pin with circular hole 11.
The bottom surface of pressing plate 5 may correspond to valve spring upper seat and offers circular groove 51, makes that pressing plate 5 is better more steady to be pressed on valve spring upper seat, simultaneously also can coated valve spring upper seat outer ring, presses down and more surely not easily rocks.Connecting rod 3 pull bar link is provided with pin, pull bar 2 correspondence offers the pin-and-hole mated with pin, and this spline structure makes the dismounting between the two more quick.
Pressing plate 5 is connected with bracing frame 4 bolt, is convenient for changing or adjusts the valve spring upper seat to be suitable for different size.Multiple circular holes 11 on depression bar 1 are interconnected, more convenient mobile adjustment.Conveniently grip force, the end of exerting pressure of depression bar 1 is provided with handle 12, and handle 12 can adopt rubber handle, contributes to anti-skidding.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
