The utility model content

At the prior art above shortcomings, the purpose of this utility model provide a kind of simple in structure, easy and simple to handle, efficiency of assembling is high, guarantee the PCV valve assembly tooling of assembly quality.

The purpose of this utility model is achieved in that the assembly tooling of a kind of PCV valve, comprises supporting seat and the rocking arm that can rotate and have handle around supporting seat up and down, and the base of fixed supporting seat; Be provided with the pipe shape pressure head of band PCV valve opening on the rocking arm near the handle place, pressure head is connected with rocking arm by detachable mechanism; The rocking arm termination is provided with the return spring that is connected with base.Described rocking arm afterbody apart from the distance of itself and supporting seat tie point less than the distance of its head apart from the supporting seat tie point.

Described detachable mechanism is connected by bolt/nail by the bar shaped hollow hole near the handle place on the connecting hole on the pressure head and the rocking arm; The position of pressure head can move forward and backward in bar shaped hollow hole scope.

Described pressure head is made of upper-part and lower member two sub-assemblies; Connecting hole is established at the upper-part top, is used for docking with the bar shaped hollow out on the rocking arm, connects by adjustable screw thread (hole/bar) between the upper and lower parts, and the lower member bottom is the working position of round tubular structure.

Also be provided with the locating piece that is used for fixing the engine cylinder cover on the base.

Compared to existing technology, the utlity model has following advantage:

1, utilize lever principle, the rocking arm of design (band pipe shape) PCV valve opening pressure head, not only simple in structure, and easy and simple to handle, laborsaving, save time.

2, Design Orientation device makes the assembling one-time-reach-place, guarantees assembly quality; Simultaneously, can assemble different model engine cylinder cover.

3, detachable pressure head structure is simple, easy to process, can change pressure head according to different PCV valves or PCV valve pocket; And pressure head is designed to Collapsible structure, to be suitable for assembling the engine cylinder cover assembling of differing heights.

4, utilize return spring, make repeatedly efficiency of assembling higher.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the utility model user mode schematic diagram.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1, the assembly tooling of the utility model PCV valve comprises supporting seat 4 and the rocking arm 8 that rotates up and down around supporting seat 4, and rocking arm 8 heads are installed one and press-fited handle 1; Rocking arm 8 is movably connected on the top of supporting seat 4 by rotating shaft near the tail end position; Be provided with the pipe shape pressure head 3 of band PCV valve opening on the rocking arm 8 near handle 1 place; The pressure head working position is round tubular structure, and internal aperture is corresponding with the external diameter of PCV valve, and external diameter is corresponding with the internal diameter of PCV valve seal gum cover.

Pressure head 3 is connected with rocking arm 8 by detachable mechanism, its detachable mechanism is made of the bar shaped hollow hole 9 on the connecting hole on the pressure head 3, the rocking arm 8 and bolt/nail, be connected by bolt/nail near the bar shaped hollow hole 9 that press-fits handle 1 place on connecting hole on the pressure head 3 and the rocking arm 8, the position of pressure head 3 can be moved forward and backward in bar shaped hollow hole 9 scopes.Rocking arm 8 afterbodys less than the distance of its head apart from support arm 4 tie points, constitute laborsaving lever apart from the distance of itself and supporting seat 4 tie points.For ease of repeating to assemble the PCV valve of next engine cylinder cover fast, rocking arm 8 terminations also are provided with return spring 5 and are connected with base 7.

In addition, pressure head 3 also can be designed to by upper-part and two combining structures that constitute of lower member; Upper-part 2 is a connector, and an end is provided with connecting hole and is used for docking with the bar shaped hollow out 9 on the rocking arm 8, and the other end is provided with the screw rod/hole that is connected with lower member, connects by adjustable screw thread (hole/bar) between the promptly upper and lower parts; Lower member one end is provided with the screw/bar that docks with upper-part, and the other end is the round tubular structure that is used for PCV valve and the assembling of PCV valve seal gum cover.Can adjust up and down by the height of regulating screw thread (screw rod) pressure head like this, to be suitable for assembling the engine cylinder cover assembling of differing heights.

Referring to Fig. 2, supporting seat 4 is fixed on the base 7, and base 7 also is provided with the locating piece 6 that is used for fixing the engine cylinder cover, and locating piece 6 can cover on shift position on the base 7 according to the engine cylinder to be assembled of different model.

Referring to Fig. 3, occupation mode of the present utility model is as follows: earlier engine cylinder cover to be assembled 10 usefulness locating pieces 6 are fixed on the base 7; Because between PCV valve and the PCV valve seal gum cover is interference fit, PCV valve seal gum cover 12 with the PCV valve is sleeved on the pressure head 3 earlier, press-fit handle 1 with hand, because lever principle, PCV valve seal gum cover will be forced in the PCV valve opening that is pressed into engine cylinder cover 10 effortlessly; Again PCV valve 12 is inserted in the endoporus of pressure head 3, press-fit handle 1 with hand, in like manner, PCV valve 12 will be forced in the PCV valve seal gum cover that is pressed into engine cylinder cover 10 effortlessly, the assembling of such PCV valve just assembling finishes, behind the pressure of cancellation hand, rocking arm 8 sets back under the effect of return spring 5, can press-fit once more.

As the PCV valve of need assembling different model, then change pressure head 3 (or telescopic bottom) by detachable mechanism.To different engine cylinder covers, then the position of running fix piece 6 and pressure head 3 makes engine cylinder cover PCV valve opening aim at pressure head PCV valve opening as need assembling PCV valve.Key of the present utility model is to use lever principle, on the basis of not dismantling cylinder cap, utilize the reset condition of engine related components, cleaning, time saving and energy saving, rationally, easily PCV valve seal cover and PCV valve are pressed in the cylinder cover PCV valve opening smoothly, be convenient to the assembling work on the production line, improve efficiency of assembling.

Above-described only is preferred implementation of the present utility model.For the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model principle, can also make some modification or improvement, these belong to protection domain of the present utility model equally.
