Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an oil application device that also serves as a valve supply. This invention relates to a valve supply/oil application device used to apply lubricating oil to the outer periphery of the shaft portion of the valve prior to insertion.

(Conventional technology) When inserting a valve into the valve guide fitted into the cylinder head of an engine, the clearance between the inner circumference of the valve guide and the outer circumference of the valve is quite tight, and the insertion will not go smoothly if it is left as is. The purpose is to make the valve slippery so that it is slippery, and to prevent it from seizing due to friction between the inner circumference of the valve guide and the outer circumference of the valve during operation after the valve is assembled to the cylinder head. Therefore, lubricating oil is applied to the outer periphery of the valve shaft prior to insertion.

Conventionally, this oil application work has been done manually by workers.

However, this oil application process had to be done evenly, which was surprisingly troublesome, and there were various problems, such as over-applying the oil and causing it to drip and be wasted.

(Problems to be solved by the invention) The present invention has been devised in view of the above-mentioned points, and it is possible to perform the application work smoothly, to apply the oil evenly, and to reduce wastage of oil. It is an object of the present invention to provide an oil application device which also serves as a valve supply and which can minimize the amount of oil applied.

(Means for Solving the Problems) The gist of the present invention is to provide a pedestal for supporting the oil storage tank described later on the inner bottom and a pedestal fixed to the pedestal, and to an oil recovery box provided with an oil passage for collecting excess oil dripping from the valve holding cylinder described later; an oil storage tank fixed on the pedestal and containing oil to be applied to the valve; A sponge or the like is inserted vertically into the bottom, the upper end is formed into a funnel shape, and a through hole is bored in the center in the axial direction, and one end is inserted into the through hole from a sponge etc. soaked in the oil stored in the oil storage tank. a valve holding cylinder into which the other end of the oil absorbing member is inserted; a valve holding cylinder which is attached to the pedestal so as to be able to move vertically within the pedestal; There is an oil application device that also serves as a valve supply, which consists of a valve height regulating bolt in contact with the valve height regulating bolt.

(Embodiments) The present invention will be described in more detail below with reference to illustrated embodiments.

In the figure, reference numeral 1 denotes an oil collection box, which has a base part 4 with a recess 2 on the top surface for receiving the head of the height regulating bolt of the valve described later and an oil passage hole 3 communicating with the recess 2 on the side surface. It is located at the inner bottom.

Reference numeral 5 denotes a pedestal fixed to the pedestal 4 with a bolt 6, and a bolt holding member 8 having a sharp valve height regulating bolt 7 threaded vertically into the center of the lower surface is tightly fitted. A recess 9 is provided, and an oil passage hole 10 communicating with the recess 2 is provided on the side surface, and a valve insertion hole 11 communicating with the recess 9 is provided on the upper surface. Reference numeral 12 denotes an oil storage tank fixed on the pedestal 5, and a valve holding cylinder described later is vertically fitted into the center of the bottom. Reference numeral 13 denotes a valve holding cylinder that is fitted vertically into the center of the bottom of the oil storage tank 12, and has an upper end opening in the shape of a funnel, a lower end abutting the pedestal 5, and a central part of its inner diameter. It is made to coincide with the valve insertion hole 11 of the pedestal 5. In addition, a through hole 14 is bored in the center of the valve holding cylinder 13 in the axial direction, and one end of the oil O.
The other end of an oil absorbing member 15 such as a sponge immersed therein is inserted.

In the illustrated embodiment, eight oil storage tanks and eight valve holding cylinders are arranged in parallel, but this is done so that the valve gripping mechanism in the valve insertion device can grip eight valves at the same time. This corresponds to the fact that

In addition, 16 in the figure is a valve insertion device, 17
is a valve gripping mechanism in the valve insertion device 16, which connects to the guide member 19 via a lever 21 by operating a guide member 19 that moves forward and backward in the horizontal direction in the figure via a cylinder 18 and a hydraulic cylinder 20. The stem of the valve V, which is loosely fitted into a vertical guide groove (not shown) provided on the surface of the guide member 19 facing the lid 22, is separated by the lid 22. It is used to close the valve so that it does not fall out and to hold the valve.

(effect) Next, the operation of the present invention will be explained.

The state shown in FIGS. 1 and 2 is the state in which the valve V is inserted into the valve holding cylinder 13 from above. In this case, the lower end of the valve V is inserted until it comes into contact with the tip of the valve height regulating bolt 7. However, the valve holding cylinder 13 has its through hole 14.
An end of an oil absorbing member 15 such as a sponge is inserted into the oil absorbing member 15 such as a sponge.
Since it always contains a moderate amount of oil, the valve V
When the valve is pulled out from the valve holding cylinder 13, an appropriate amount of oil is evenly applied to its shaft.

Incidentally, as shown in the drawing of the present invention, the valve insertion device 16
When used in conjunction with the valve gripping mechanism 1, when the shaft of the valve V is gripped by the valve gripping mechanism 17, the entire valve insertion device 16 rises, and the valve gripping mechanism 1
7 rises while holding the valve, so the valve is automatically pulled out from the valve holding cylinder 13.

Further, when the valve V is pulled out from the valve holding cylinder 13 and oil is applied, some excess oil drips downward, but the dripped oil flows from the recess 9 provided in the pedestal 5 through the oil passage hole 10. Alternatively, the oil is guided from the recess 2 of the platform 4 through the oil passage hole 3 into the oil recovery box 1 and stored therein. Therefore, oil can be used without wasting it.
Incidentally, if the tip of the regulating bolt 7 is made sharp as in the embodiment, it is advantageous to further improve the oil recovery rate.

(Effects of the invention) Since the present invention has the above-described structure and function, it is possible to uniformly and appropriately apply lubricating oil to the valve shaft by simply inserting the valve into the valve holding cylinder and pulling it out. be. Therefore, the oil application work becomes extremely easy and the work can be done quickly. Further, unlike the conventional method, a large amount of oil is not wasted during application, and furthermore, it is mechanically simple and can be manufactured at low cost, and has many practical advantages.
