Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an engine cylinder block cleaning apparatus,

The present invention relates to an engine cylinder block cleaning apparatus of a robot nozzle type, more particularly, to a method of cleaning an engine cylinder block hole or a surface of an engine cylinder block cleaning apparatus through a first coolant cleaning operation, To a robot nozzle type engine cylinder block cleaning apparatus for removing moisture, residual chips, cutting oil, and the like from an engine cylinder block hole or a surface thereof.

Generally, the engine cylinder block is composed of an oil passage for supplying oil to the engine parts for lubrication, and a water jacket for supplying water to cool the engine. Accordingly, the engine cylinder block is a component having a plurality of holes and a surface having a relatively complicated shape, and there is a problem that metal chips, cutting oil,

In order to solve this problem, Korean Patent Registration No. 10-1194110 discloses a coolant washing chamber for removing foreign substances adhering to a cylinder block by injecting a coolant into a cylinder block as shown in Fig. 1 of this specification, And an air blow chamber for removing coolant remaining in the cylinder block by injecting high-pressure air after the washing. The tilting apparatus is mounted inside the chamber so that the cylinder block can move between the coolant washing chamber and the air blow chamber, A coolant and air blower cleaner for an automobile engine cylinder block is known, which is composed of a partition wall having a tilting device entrance and exit inside the chamber so that the spaces of the coolant washing chamber and the air blow chamber are completely separated from each other.

However, since the cleaning is performed in a state where the coolant injection nozzle and the air blow nozzle are fixed, it is difficult to completely remove the complicated shape or foreign substances such as metal chips and cutting oil remaining in the holes in the engine cylinder block.

In order to solve the above-mentioned problems, in the present invention, coolant and oil passages of the engine cylinder block through the one tilting unit and the robot arm, coolant And an object of the present invention is to provide a robot-nozzle-type engine cylinder block cleaning apparatus that performs washing more efficiently by moving a washing nozzle and an air blow nozzle to target a cleaning area.

In order to accomplish the object, there is provided an apparatus for cleaning an engine cylinder block of a robot nozzle type, comprising: a cylinder block block seating portion on which an engine cylinder block is mounted and a fixed pin for fixing both sides of the engine cylinder block by a fixed pin cylinder; A tilting unit tilted downward by 90 ° by a tintil cylinder and a plurality of coolant washing nozzles provided in an inner 'П' shape to move left and right along the moving direction of the washing unit, and a robot equipped with an air blow nozzle And a first chamber in which the arm, the tilting unit, the coolant washer nozzle unit, and the robot arm are built in.

In another aspect of the present invention, a coolant tank for supplying coolant and air to the coolant washer nozzle and an air blow nozzle, respectively, and a second chamber in which the air tank is installed are provided on the side of the first chamber.

According to another aspect of the present invention, there is provided a cylinder block door opening / closing opening / closing unit for allowing the engine cylinder block to vertically move in and out of the first chamber, a coolant injected from the washer nozzle unit and a chip cleaned in the engine cylinder block, And a trench to be discharged is provided.

As described above, the robot-nozzle-type engine cylinder block cleaning apparatus according to the present invention cleans the engine cylinder block hole or the chips and cutting oil left on the surface through a cleaning operation through a coolant washer nozzle moving in the first direction The second cylinder block is cleaned with an air blown nozzle mounted on the robot arm, thereby effectively removing moisture, remaining chips and cutting oil from the engine cylinder block hole or surface.

2 is a top view of an engine cylinder block cleaning apparatus of the robot nozzle type according to the present invention.
3 is a side view of an engine cylinder block cleaning apparatus of the robot nozzle type according to the present invention.

FIGS. 2 and 3 are top and side views, respectively, of a robot-nozzle-type engine cylinder block cleaning apparatus according to the present invention.

(EN) An engine cylinder block cleaning apparatus of a robot nozzle type includes a cylinder block seating portion (11) on which an engine cylinder block (E) is seated and a fixing pin A tilting unit 10 tilted downward by 90 ° with a tilt cylinder 15 about a tilting axis 14 and a plurality of coolant washer nozzles 21 on an inner side in an П shape A robot arm 30 on which the air blow nozzle 31 is mounted and a tilting unit 10 and a coolant washer nozzle 31. The washing nozzle unit 20 moves left and right along the washing unit moving shaft 22, And a first chamber (40) in which the unit (20) and the robot arm (30) are housed.

A coolant tank 51 and an air tank 52 for supplying coolant and air to the coolant washer nozzle 21 and the air blow nozzle 31 are provided on the side of the first chamber 40, And a second chamber 50 embedded therein.

A cylinder block inlet / outlet 41 is opened and closed to allow the engine cylinder block E to vertically move in and out, and a coolant and an engine cylinder to be sprayed from the washer nozzle unit 20 are arranged on the upper side of the first chamber 40, Characterized in that a trench (42) is provided in the block (E) through which the cleaned chips are discharged.
