Description
Technical field
The utility model relates to a kind of spring disassembly mechanisms.Specifically, be for dismantle automobile fuel engine can be changed into
The tooling of valve return torsional spring.
Background technique
In automobile manufacture industry, for make automobile fuel engine variable intake valve reset, at variable intake valve all
It is provided with reduction torsion spring.As shown in Figure 1, this torsional spring is by being in that integrated connects between two coaxial springs, two coaxial springs one end
Together, the front of motor of two coaxial springs is overhanging to same direction, to constitute a U-shaped torsional spring.It is horizontal when installation
Portion is connected to engine cylinder by tabletting and screw and covers, and vertical part i.e. two overhanging end is stuck under rocker arm.This spring
Intensity it is big, elastic force is larger, and in the narrow space.Traditional method for dismounting is to pin torsional spring with hand, is screwed solid
The fixed screw for turning round Huang need to pin with strength torsional spring with hand in the moment for screwing off screw.Unless you give your whole attention to it, torsional spring just will pop up, and be easy to make
At casualty accident.It not only dismantles relatively difficult but also very dangerous.
Utility model content
Problem to be solved in the utility model is to provide a kind of dismounting reset spring tooling.It is dismantled using this tooling
Reduction torsion spring on engine variable inlet valve, not only facilitated, but also safety.
The above problem to be solved in the utility model is realized by the following technical scheme:
The dismounting reset spring of the utility model be with tooling feature include substrate, the substrate be rectangle, it is in front
There are supporting block in two sides.The supporting block is strip plate, and the plate face of plate face and substrate is perpendicular, longitudinal parallel, thereon
End is separately fixed at substrate two sides in front, the concave arc that lower end has convenient for cooperating with cylinder cap camshaft.The both sides of substrate have
Anti- T-shaped block, the transverse part front end of anti-T-shaped block is by pin-hinges on the substrate two sides of neighbouring supporting block.Two anti-
There is connecting rod between the upper rear end of T-shaped block transverse part, the longitudinal direction of connecting rod is intermediate operating stick, and operating stick lower end is fixed on connecting rod
It is intermediate.The outside of the connecting rod is protruded except the back of substrate, and there are pin ear in the back two sides of substrate, have pin between two pin ears
Axis and hook.The hook is quarter butt, and there is hole in its underpart, and the pin shaft penetrates in hole.On the side of the hook adjacent substrates
End is inclined-plane, and there is a transverse groove in hook side under inclined-plane, under off working state, is caught in the transverse direction in moving type outside connecting rod
In slot;Tension spring is connected between hook lower end and substrate downside.
Wherein, the centre of the operating stick, which has, makes the recurvate inflection point of its upper section.
As can be seen from the above scheme, when the reduction torsion spring on automobile fuel engine variable intake valve need to be dismantled, first
It is stuck in the concave arc of supporting block lower end on the camshaft of cylinder cap.Then, make hook around pin shaft along inverse hook upper end pusher with hand
Clockwise rotates and is detached from rocker arm.Later, hand-held operation bar pushes and pulls forward, makes two anti-T-shaped blocks together before its transverse part
The hinge joint at end rotates forward upwards.Later, the small hook of the vertical part lower end of two anti-nail-shaped blocks is made to catch on two respectively coaxially
The front of motor of spring.Finally, holding operating stick and continuing to push and pull clockwise, to easily realize variable intake valve
On reduction torsion spring disassembly.It compared with the method for dismounting in background technique, is not required to pin torsional spring with strength with hand, can avoid torsional spring
It pops up, cause casualty accident.It not only removes and is easier, but also eliminate security risk, it is very safe.
Detailed description of the invention
Fig. 1 is the dismounting reset spring tool structure schematic diagram of the utility model;
Fig. 2 is the top view of Fig. 1.
Specific embodiment
As depicted in figs. 1 and 2, the dismounting reset spring tooling of the utility model includes substrate 13.The substrate 13 is
There are supporting block 11 in rectangle, two sides in front.The supporting block 11 is strip plate, and plate face and the plate face of substrate 13 are mutually hung down
Directly, longitudinal parallel, the upper end is separately fixed at the two sides in front of substrate 13, and lower end, which is machined with, to be convenient for and cylinder cap camshaft
The concave arc 12 of cooperation.The both sides of substrate 13 are provided with anti-T-shaped block 1, and the transverse part front end of anti-T-shaped block 1 is cut with scissors by pin 8
It connects on 13 two sides of substrate of neighbouring supporting block 11.It is connected with connecting rod 8 between the upper rear end of two 1 transverse parts of anti-T-shaped block, even
The longitudinal direction of bar 8 is intermediate to be provided with operating stick 5, and 5 lower end of operating stick is fixed on the centre of connecting rod 8.Wherein, in the operating stick 5
Between have and make the recurvate inflection point 6 of its upper section.The outside of the connecting rod 8 is protruded except the back of substrate 13, substrate 15
Back two sides are provided with pin ear 3, are connected with pin shaft 9 and hook 4 between two pin ears 3.The hook 4 is quarter butt, its underpart processing
There is hole, the pin shaft 9 penetrates in hole.The side upper end of 4 adjacent substrates 13 of hook is inclined-plane 7, the hook 4 under inclined-plane 7
The side is machined with transverse groove, under off working state, is caught in the transverse groove outside connecting rod 8 in moving type.4 lower end of hook and base
Plate is connected with tension spring 2 between 13 downside.
