Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Please refer to Figures 1-4 The technical scheme provided by the embodiment is as follows:

[0025] A turnover mechanism for wear -resistant cast ball processing, including base 1, the inside of base 1 is equipped with the placing groove 2 for placing quenching box, the top of base 1 is provided with turntable 4, and the turntable 4 is driven by the drive motor at the bottom, and both sides of the turntable 4 are equipped with turnover frame 3, and the turnover frame 3 is connected with the turntable 4 by support 5, one of the turnover frame 3 can be rotated to the top of the placing groove 2 by the rotation of the turntable 4, and the side of the turnover frame 3 close to the turntable 4 is provided with a rotating shaft, and the rotating shaft is installed in the end of the support 5 through the bearing, and the support 5 is equipped with pneumatic positioning assembly for limiting the rotation of the rotating shaft, and the side of the mounting seat 13 of the turnover frame 3 is provided with mounting shaft 14.

[0026] The drive motor controls the rotation of the turntable 4, realizes the alternate use of the two turnover frames 3, when one side of the turnover frame 3 loads the wear -resistant cast ball to be quenched, the other side can be automatically rotated to the top of the quenching box and completes the dumping operation.

[0027] Further including motor 11, motor 11 is installed in the top of base 1 through motor frame 6, and motor 11 is connected with mounting seat 13 through telescopic coupling 12.The input port of telescopic coupling 12 is in transmission connection with the output shaft of motor 11, and the output port of telescopic coupling 12 is in spline connection with mounting shaft 14.

[0028] Specifically, when the turnover frame 3 is rotated to the upper side of the placing groove 2, the automatic docking with the mounting shaft 14 can be realized through the telescopic movement of the telescopic coupling 12, and the telescopic coupling 12 is rotated by starting the motor 11, and since the output port of the telescopic coupling 12 is connected with the mounting shaft 14 by means of the spline, the turnover frame 3 can be automatically turned over, so that the wear-resistant cast ball in the turnover frame 3 falls into the quenching tank below.

[0029] The pneumatic positioning assembly comprises a double-outlet cylinder 7, and a connecting plate 8 is arranged on the telescopic end of the double-outlet cylinder 7. Positioning grooves are arranged on both sides of the rotating shaft, and a positioning rod 10 is arranged on the connecting plate 8 and matched with the positioning grooves. Guide holes 9 are arranged on both sides of the support 5, and the guide holes 9 are matched with the positioning rod 10 in a clearance fit.

[0030] Specifically, the connecting plate 8 can drive the positioning rod 10 to move through the telescopic movement of the double-outlet cylinder 7, and the rotating shaft can be locked when the positioning rod 10 enters the positioning groove through the guide hole 9, so that the stability of the turnover frame 3 is ensured before the turnover frame 3 is connected with the telescopic coupling 12.

[0033] Working principle: the driving motor drives the rotating disc 4 to rotate, so that the turnover frame 3 loaded with wear-resistant cast balls can be alternately rotated to the upper side of the placing groove 2. When the turnover frame 3 is rotated to the upper side of the placing groove 2, the automatic docking with the mounting shaft 14 can be realized through the telescopic movement of the telescopic coupling 12. After the motor 11 is started, the telescopic coupling 12 is rotated, and since the output port of the telescopic coupling 12 is connected with the mounting shaft 14 by means of the spline, the turnover frame 3 can be turned over, so that the wear-resistant cast ball in the turnover frame 3 falls into the quenching tank below, and the pouring operation of the wear-resistant cast ball is completed.
