Description

[Detailed explanation of the invention] (Field of industrial application) This invention is used to wash and remove chips from a workpiece such as a cylinder block machined after casting using high-pressure water sprayed from a nozzle. Regarding cleaning equipment.

(Prior Art) Conventionally, as a cleaning device of the above-mentioned example, for example, there is a device described in Japanese Utility Model Application Publication No. 58-139774.

That is, an air blow and cleaning box with a cleaning liquid receiving tank formed at the bottom is provided, and an upper cleaning nozzle connected to the piston rod of the lifting cylinder is installed to clean the work carried in by the carrying member through the opening of this box. This cleaning device is equipped with one nozzle and a second nozzle for side cleaning connected to a piston rod of a cylinder that moves forward and backward.

In this conventional device, when a workpiece is carried into the box by the above-mentioned carrying member, the piston rod of each cylinder is lowered and moved forward, and the first
and each second nozzle is brought close to the above-mentioned work, and by jetting the cleaning liquid from each of these nozzles,
Clean and remove chips from machined workpieces.

However, in this conventional device, the height of the second nozzle for side cleaning cannot be regulated by the lifting side elements such as the lifting cylinder and the first nozzle. It is necessary to move the side cleaning unit including the second nozzle up and down using a separate unit lifting means.
In order to make it possible to clean irregularly shaped workpieces, there was a problem in that the structure became complicated.

(Purpose of the invention) This invention provides a cleaning device in which the height of the side cleaning unit can be set by the lowering movement of the lifting head, and which can clean odd-shaped workpieces with a simple configuration. purpose.

(Structure of the device) This device is a cleaning device for cleaning a plurality of odd-shaped workpieces, and includes an elevating head that lifts and lowers a first nozzle for upper cleaning, and a second nozzle for side cleaning using resilient means. The cleaning device is equipped with a side cleaning unit that is elastically installed in the direction, and an engaging member that comes into contact with the side cleaning unit during the lowering movement of the elevating head and restricts the vertical position of the second nozzle of the unit. Features.

(Effect of the invention) According to this invention, when the elevating head equipped with the first nozzle for upper washing descends, the height of the side washing unit is set via the engaging member, so that the height of the side washing unit is set. The vertical position of the second nozzle is regulated to a predetermined position corresponding to the shape of the workpiece.

That is, since the heights of the side cleaning unit and the second nozzle can be determined by the lowering movement of the elevating head, there is an effect that irregularly shaped workpieces can be cleaned with a simple configuration.

(Example) An example of this invention will be described in detail below based on the drawings.

The drawing shows a cylinder block cleaning device, with the first
In the drawings to FIG. 3, cylinder blocks 1 as workpieces to be cleaned are sequentially conveyed by a lift conveyor 2 in an inverted position.

The above-mentioned cylinder block 1 includes a cylinder bore portion 3 into which a piston (not shown) is inserted;
The water jacket 4 has a water jacket 4 formed around the bore portion, a hole 5 for removing sand formed outside the water jacket 4, and an oil pan surface 7 formed at the lower end of the skirt portion 6.

Cylinder block 1' for 1800 c.c. and cylinder block 1'' for displacement 1600 c.c. shown in Fig. 5 are as follows.
Although they have different shapes, the distance from the oil pan surface 7 to the center of the sand removal hole 5 is equal to each other.

In this way, in order to clean the cylinder blocks 1, 1', 1'', each having a different shape, after casting and machining, a cylinder (not shown) is installed upright above the cylinder block conveyance system. A lifting head 9 is attached to the lower end of the piston rod 8 of this cylinder.

At the center of the lower surface of the above-mentioned elevating head 9, there are first nozzles 10 for upper cleaning, the number of which corresponds to the cylinders, for example, four.
is installed. Each of these first nozzles 10...
1 is a nozzle in which the lower part of the nozzle 10 is located inside the cylinder bore 3 when the elevating head 9 is lowered, and has a plurality of injection holes 11 for ejecting high-pressure water as a cleaning liquid.

By the way, side cleaning units 13, 13 which can be moved up and down by a pair of front and rear lifting guides 12, 12 are arranged on both left and right sides of the cylinder block conveyance system.

These left and right side cleaning units 13, 13 have a substantially symmetrical structure, and their specific structure is as follows.

That is, the above-mentioned front and rear lifting guides 12, 12
Cylindrical sliders 14, 14 are fitted in such a way that they can move up and down, and an elevating plate 15 having an L-shaped cross section is stretched between these sliders 14, 14. The cylinder 17 is fixed.

Also, the piston rod 18 of the cylinder 17 mentioned above
A movable plate 19 is provided which moves forward and backward in conjunction with the movable plate 19, and this movable plate 19 has a second nozzle 20 for side cleaning inserted into the hole 5 for removing sand.
...is fixed.

Guide brackets 21, 21 are provided upright on the upper surface of the elevating plate 15, while the movable plate 1
The guide pins 22 fixed on both sides of the upper part of the
It is configured to be slidably inserted into the guide hole 23 in the guide bracket 21 described above to guide the forward and backward movement of the second nozzle 20.

Further, an abutting protrusion 24 is fixed to the upper surface of the above-mentioned elevating plate 15, while a second nozzle 20 is connected between the fixed base 25 at the lower end of the elevating guide 12 and the slider 14 via the elevating plate 15 etc. A coil spring 26 is tensioned as a resilient means to constantly bias upward.

Further, a flange portion 27 that prevents the slider 14 from slipping out is integrally formed at the upper end of the axis of the above-mentioned lifting guide 12.

Incidentally, engaging members 28, 28 are bolted and fixed to both sides of the lower surface of the above-mentioned elevating head 9 so as to correspond to the abutting protrusions 24 shown in FIG.

This engaging member 28 comes into contact with the above-mentioned contact protrusions 24, 24 of the side cleaning units 13, 13 during the lowering movement of the elevating head 9, and the units 13, 1
The vertical position of the second nozzle 20 of No. 3 is regulated.

The illustrated embodiment is configured as described above,
The action will be explained below.

First, from the state shown in Figure 1, the cylinder (not shown)
When the elevating head 9 is lowered in the direction of arrow a in the figure through the piston rod 8, the elevating head 9
