Description

[Detailed Description of the Invention] The present invention relates to a grease application device.

Conventionally, grease in a container is applied to a brush and the brush is used to apply the grease to the surface to be coated, but when the brush is operated manually in this way, it is difficult to uniformly apply the grease.

This idea was created with these points in mind.
This makes it easy to apply grease uniformly.

Next, one embodiment of the present invention will be described based on the drawings.

1 is a coating device main body, and this coating device main body 1 is:
An upper head cover 2 and a lower body 3 are fixed with bolts 5 via an intermediate gasket 4.

Further, on one side of the head cover 2, a mounting flange 7 of an adapter 6 connected to a grease metering pump (not shown) is fixed with bolts 8, and the inner end of the adapter 6 is opened into the internal chamber 9 of the head cover 2. .

Further, the body 3 is provided with a plurality of through holes 11 in the vertical direction that communicate with the chamber 9, and an open/close hole 12 that contacts the lower end of each through hole 11 is provided in the left/right direction. A slit-shaped grease discharge port 13 is provided at.

Further, the mounting flange 15 of the holding part 14 is fixed to one end surface of the body 3 with a bolt 16, and the hole 17 in the center of the holding part 14 and the opening/closing shaft 18 of the opening/closing hole 12 are fitted so as to be freely forward and backward. A positioning roller 19 is fitted onto the outer circumferential surface of the holding portion 14 to keep the distance between the coating surface and the nozzle and brush constant even if the size of the object to be coated changes, and the roller 19 is locked by a retaining ring 21. 22 is an operating knob for the opening/closing shaft 18.

Further, an L-shaped support part 23 is fixed to the other side of the head cover 2 with bolts 24, and the lower end of this support part 23 and the convex part 2 of the mounting flange 15 are fixed to the other side of the head cover 2.
5, and this support 26 is fixed with bolts 27 on both sides. Further, a plurality of brush mounting portions 29 are arranged laterally in the inner recess 28 of the support 26, and a presser plate 32 is further fixed to the inner side of the support 26 via the brush mounting portions 29 with screws 31. A recess 33 is formed in each of the brush mounting portions 29, and the recess 33 is supported by the support 26 so as to be movable in the vertical direction.

Further, a screw hole 34 is provided at the top of each mounting portion 29, and a knob 35 for vertically operating the mounting portion 29 is provided in the screw hole 34.
Two upper and lower locking holes 36 and 37 are provided in the middle part of the locking bolt 38 inserted into the support 26.
The head 39 of the brush 41 is fitted into one of the locking holes 36, 37, and a brush 41 is fixed to the lower end of each mounting portion 29. Reference numeral 42 designates a retraction hole for the head 39 of the locking bolt 38. In addition, in the figure, the brush 41a at the left end is the same as the other brushes 41.
The brush 41a is formed to be wider than the brush 41a to ensure a minimum coating width, and the brushes 41b can cope with an increase in the coating width.

Then, the grease press-fitted into the chamber 9 from a grease supply pump (not shown) via the adapter 6 passes through the through hole 11 and opening/closing hole 12 opened to the width of the grease application surface A by the opening/closing shaft 18. Then, it flows out from the slit-shaped discharge port 13 to the grease application surface A below. When this grease application surface A is rotated in the direction of the brush 41, the grease adhering to this surface A is evenly smoothed out by the brush 41. Also, for threaded pipe-shaped products, it is possible to completely apply the product to the bottom of the thread. The grease application surface A is rotated in a fixed position by being locked by the positioning roller 19.

In addition, if the width of the grease application surface A is large, the opening/closing shaft 18 is pulled outward accordingly, and each through hole 11 and opening/closing hole 12 is opened to the grease discharge port 13 within the range of the width of the grease application surface A. do.

In addition, if the circumferential radius of the grease application surface A is large, the bolts 2 on both sides that fix the support 26
7 is loosened, and the support 26 is rotated by an arbitrary angle in the clockwise direction in FIG.

Also, if the head 39 of the locking bolt 38 is pulled into the lead-in hole 42, the knob 35 is pulled up and the mounting portion 29 is slid upward, and the head 39 is fitted into the lower locking hole 37, The brush 41 can be positioned higher, and thereby unnecessary brushes 41 that do not correspond to the open portion of the opening/closing hole 12 can be evacuated upward.

In this embodiment, the support 26 and the presser plate 3 are
2 to hold each mounting portion 29 and fix the support 26 to the side surface of the head cover 2 via the support portion 23. However, instead of this structure, each mounting portion 29 is held directly on the side surface of the body 3. Brush mounting part 29
It is also possible to adopt a structure in which the mounting portion 29 is held by the recess 28 of the support 26 directly fixed to the body 3. Note that with this structure, support 26
The rotation cannot be adjusted.

As described above, according to the present invention, a slit-shaped grease discharge port is provided on the lower side of the applicator main body connected to the grease supply pump, and a grease application surface is moved from the grease discharge port along the grease discharge port. Since the brush is provided, the grease pumped from the grease supply pump can be applied to the grease application surface from the slit-shaped grease discharge port and can be evened out evenly by the brush, which is much easier than the conventional manual method. No uneven application or burden. Since the brush is separated from the grease discharge port to the side where the grease application surface moves as described above, it becomes possible to uniformly apply not only a low viscosity material but also a high viscosity material such as grease. Furthermore, since the present invention is a two-point contact type in which the roller and brush are in contact with the grease application surface, it is suitable for applying grease to the outer peripheral surface of a cylindrical workpiece, and the brush is parallel to the grease discharge port. Since the brush is pivoted so that its rotation can be adjusted while maintaining its condition, even if the outer diameter of the cylindrical workpiece is changed, the degree of contact between the brush and the workpiece can be optimized by adjusting the rotation of the brush. It can be set to the following state. Further, in the present invention, the opening/closing shaft is slidably fitted into the opening/closing hole in the slit direction provided inside the grease discharge port, so that the degree of opening of the grease discharge port in the slit direction is adjusted.
The grease application width can be adjusted as desired using the opening/closing shaft.
