[0007] Figure 1 This is a schematic diagram of the overall structure of the washing machine rear tub bushing installation and positioning fixture described in this utility model;

[0008] Figure 2 This is a schematic diagram of the structure of the driving gear and the driven gear in the flipping mechanism of this utility model. Detailed Implementation

[0009] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0010] Example:

[0011] like Figure 1 , Figure 2 The washing machine rear tub bushing installation and positioning fixture shown includes a rear tub bushing clamping mechanism 1 and a rear tub bushing positioning mechanism 2. The rear tub bushing clamping mechanism 1 includes a track 11, on which a lifting mechanism 12 is mounted. The lifting mechanism is driven by a motor to move on the track. The lifting mechanism includes a vertically mounted hydraulic telescopic rod 13, and a flipping mechanism 14 is mounted at the lower end of the hydraulic telescopic rod. A gripping claw 15 for gripping the rear tub bushing is mounted on one side of the flipping mechanism. The gripping claw 15 can rotate as the flipping mechanism rotates. The rear barrel bushing positioning mechanism 2 is located below the rear barrel bushing clamping mechanism 1 after being rotated 180° clockwise or counterclockwise from a horizontal position. The rear barrel bushing positioning mechanism 2 includes a track 21, a bracket 22, and a positioning shaft 23. The bracket 22 is mounted on the track 21 and moves left and right on the track 21 by a motor. The positioning shaft 23 is horizontally mounted on the bracket 22. The left end of the track 21 is equipped with a rear barrel injection molding mold 3, and the right side of the rear barrel injection molding mold is provided with a rear barrel bushing mounting hole 31.

[0012] Preferably, the flipping mechanism includes a drive motor, a drive gear 4 is mounted on the shaft of the drive motor, and a semi-circular driven gear 5 is mounted on the lower end of the hydraulic telescopic rod 13. The drive gear meshes with the driven gear, and the motor drives the drive gear to rotate, causing the flipping mechanism to perform a flipping action.

[0013] During the whole tool work, the rear bucket shaft sleeve clamping mechanism first operates, the grabbing claw moves to the rear bucket shaft sleeve placing point, the lifting mechanism works, the grabbing claw stretches downward to grab the rear bucket shaft sleeve, after grabbing the rear bucket shaft sleeve, the grabbing claw rises and moves to the left upper side of the rear bucket shaft sleeve positioning mechanism (the position of the left upper side of the rear bucket shaft sleeve positioning mechanism is a fixed position set by the equipment, which can make the grabbing claw turn downward and put the rear bucket shaft sleeve into the positioning shaft of the rear bucket shaft sleeve positioning mechanism 2), then the rear bucket shaft sleeve is put into the positioning shaft, after the action is completed, the grabbing claw rises and moves to the initial position. At this time, the rear bucket shaft sleeve positioning mechanism works to move to the rear bucket injection molding mold direction until the rear bucket shaft sleeve is put into the rear bucket injection molding mold, the moving distance of the rear bucket shaft sleeve positioning mechanism is controlled by the motor driving it to move, the motor can be manually operated or replaced by a timer to control, to ensure that the rear bucket shaft sleeve positioning mechanism can send the rear bucket shaft sleeve into the rear bucket injection molding mold every time; then the injection molding process starts, the injection molding equipment injects into the rear bucket injection molding mold, the rear bucket shaft sleeve is directly embedded in the formed washing machine rear bucket, eliminating the process of installing the rear bucket shaft sleeve. After completing the injection molding, the rear bucket shaft sleeve positioning mechanism 2 retreats to the initial position and waits. The cycle is repeated.
