摘要： PROBLEM TO BE SOLVED: To wash large-sized parts in high clearness by slantly fixing parts to be washed on a rotary table and disposing many spray nozzles, and washing parts to be washed in order and in stepwise by executing a washing with high- pressure city water/pure water and dewatering drying, etc., with dry air by oscillating nozzle action when the table is in rotating state. SOLUTION: Washing is started while rotating parts to be washed 2 with a rotary driving part 18 after carrying large-sized parts 2 from an opening/ closing cover 6 part at an upper part of a washing chamber 7, putting the parts on the inclined base 10 of a rotary table 11, fixing the parts with a pressing metal fittings 8 and inclining the parts 2 with an inclination screw 9. At first, the water in a city water tank 28 is sprayed in oscillating from a spray nozzle 12 through a high pressure pump 19 and a high-pressure water piping 17 to execute prewashing. Then the pure water in a pure water tank 27 is sprayed in oscillating from a spray nozzle 12 through a high-pressure pump 19 and the high-pressure water piping 17 to execute main washing with the pure water. Then the air from a dry air member 15 is sprayed from the spray nozzle 12 to execute dewatering and the washing is finished.

摘要： PROBLEM TO BE SOLVED: To improve a washing effect and to drastically decrease the space as a device by making it possible to oscillate ultrasonic waves from all directions (six directions) without allowing ultrasonic oscillators to face each other in one tank. SOLUTION: The one washing tank 1 is internally provided with two treating regions B, C. The ultrasonic oscillator for making oscillation in the three directions so as not to face each other is installed in the one region. The ultrasonic oscillator capable of making oscillation so as not to face each other in the unoscillated three directions in the former is installed in the other region. A work transferring-in and out port 13 is disposed at the center of right and left treating vessels. Inside transporting link arms 2 for moving the work 4 from the transferring-in and out port of the tanks to the right and left treating sections B, C is installed in the tanks.

摘要： PURPOSE:To provide a brush capable of sufficiently removing the stains which remain without being removed by general brush cleaning in the groove parts of very small grooves microscopically observed to exist on the worked surfaces of machined parts which are often insufficiently cleaned. CONSTITUTION:This rotary composite brush is constructed by combining a slightly large-sized brush part 1 (generally 300 to 100mum) having rigidity and a brush part 2 (30 to 1mum) of extremely fine fibers within one brush. From overall rough cleaning to precise cleaning are simultaneously executed by this composite brush. The exchange intervals of the brush and the washing time are decreased by adoption of such composite brush.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a time lag between the lift operations of left- and right-side lift driving sections by making the number and numbers of teeth of the lift rotation transmission gears of the left-side lift driving section equal to those of the right-side lift driving section. SOLUTION: When a work 21 placed on a loading conveyor 19 is transferred to a preliminary cleaning both 22 by means of an interlocked arm 13 for delivering work, a left-side transfer lift driving section 1 transmits the rotation of a lift driving motor 2 to an lift driving screw 3 and a nut 4 through transmission gears A and B. In addition, a right-side transfer lift driving section 20 transmits the rotation of a spline shaft 6 directly coupled with the motor 2 to a feed screw 3 and a nut 4 through transmission gears C and D. Therefore, the left- and right-side transfer lift driving sections 1 and 20 can be moved upward and downward by the same distance at the same speed.

摘要： PURPOSE:To eliminate the need for structural countermeasure for preventing moisture in a driving part, to prevent generation of rust, to prolong the service life of the driving part and to miniaturize a washing chamber by providing a partition for preventing liquid leakage in an operating transfer shaft between the supporting part of a brush in the washing chamber and a driving mechanism part in the outside of the washing, chamber in order to protect the driving mechanism part from splashing water. CONSTITUTION:A partition part is provided in an operating transfer shaft 9 between a brush supporting part 10 for water washing in a washing chamber 1 and an X, Y, Z-driving part 2 provided outside the washing chamber 1. The partition part has a structure for preventing liquid leakage which is freely moved in the X, Y and Z directions. In other words, sealing of X-movement is constituted of a right and left enfolding type plate connection member 6. Sealing of Y-movement is constituted of a back and forth folding type billows member 5. Sealing of Z-movement is constituted of an upward folding cylindrical bellows member 4. Thereby the transfer shaft 9 for transferring operation from the driving part 2 provided outside the washing chamber 1 is easily moved in the X, Y and Z directions. Operating power is accurately transferred to the brush supporting part 10 for water washing.
