[0023] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0024] The present invention relates to an improvement on an ultrasonic cleaning machine, and proposes an ultrasonic cleaning machine that can be lifted synchronously. The ultrasonic cleaning machine, through the setting of a synchronous lifting unit 5a and a matching unit 5b, utilizes the matching of multiple synchronous gears 5a1, a first transmission chain, a first lifting gear 5a2, a second lifting gear 5b1 and a second transmission chain, and can perfectly realize the synchronous lifting of each end and each side of a lifting mold frame 4, thereby ensuring the lifting quality and cleaning efficiency; at the same time, there is no need to reserve a cylinder stroke, thereby reducing the occupied space of the equipment and improving the space utilization rate.

[0025] See also Figure 1-6As shown, there is shown a synchronously lifting ultrasonic cleaning machine, comprising a frame 1, a plurality of working slots 2 arranged in sequence from one end to the other end of the frame 1, a plurality of cleaning frames 3 for storing workpieces to be cleaned, and a translation lifting mechanism for driving the plurality of cleaning frames 3 to sequentially pass through the plurality of working slots 2, the translation lifting mechanism comprising a lifting mold frame 4 that can be lifted and lowered on the frame 1, a first driving assembly 5 for driving the lifting mold frame 4 to move, a translation mold frame 6 that can slide on the lifting mold frame 4 along the arrangement direction of the plurality of working slots 2, a plurality of hooks 7 arranged at the bottom of the translation mold frame 6 for hooking the cleaning frames 3, and a second driving assembly 8 for driving the translation mold frame 6 to move;

[0026] The first driving assembly 5 includes a plurality of synchronous lifting units 5a which are arranged along the arrangement direction of the plurality of working slots 2 and are respectively located above both sides of the arrangement direction of the plurality of working slots 2, and a plurality of matching units 5b which are respectively arranged below the plurality of synchronous lifting units 5a in a one-to-one manner. The synchronous lifting unit 5a includes a coaxially connected synchronous gear 5a1 and a first lifting gear 5a2, and two first transmission chains which are respectively connected to the plurality of synchronous gears 5a1 on each side. The matching unit 5b includes a corresponding second lifting gear 5b1 which is arranged directly below each first lifting gear 5a2, and a plurality of second transmission chains which are respectively connected to each two corresponding first lifting gears 5a2 and second lifting gears 5b1. The plurality of second transmission chains are respectively connected to both sides of the lifting mold frame 4. The rotation axis of the second lifting gear 5b1 extends in the horizontal direction and is parallel to the rotation axis of the first lifting gear 5a2. The first driving assembly 5 also includes a motor 5c for respectively driving at least one synchronous gear 5a1 on each side to rotate.

The tensioning box 9a is fixedly connected to the lifting mold frame 4, and the two ends of the second transmission chain are respectively connected to the two tensioning bolts 9b. Through the setting of the tensioning assembly 9, the tightness of the second transmission chain can be effectively adjusted. Specifically, the movement and fixation of the tensioning bolt 9b can be realized by the looseness and tightness of the locking nut 9c, and the tightness of the second transmission chain can be realized by the sliding of the tensioning bolt 9b in the up and down directions.

Through the arrangement of the first conveying roller assembly 17 and the bearing platform 18, the unloaded cleaning frame 3 can be carried on the bearing platform 18 and sent to the first conveying roller assembly 17 after being output from the unloading platform 16, and then sent back to the side of the loading platform 15 through the first conveying roller assembly 17, and finally sent back to the loading platform 15 through the bearing platform 18, so that the automatic rotation of the cleaning frame 3 is realized, thereby realizing a fully automatic cleaning process and ensuring the cleaning efficiency.

[0037] Furthermore, both the loading platform 15 and the unloading platform 16 have a second conveying roller assembly 20 and the conveying direction is consistent with the conveying direction of the first conveying roller assembly 17. Two slide rails 21 are arranged along the conveying direction perpendicular to the first conveying roller assembly 17 between the first conveying roller assembly 17 and the loading platform 15 and between the first conveying roller assembly 17 and the unloading platform 16, and the supporting platform 18 is slidably arranged on the two slide rails 21.
