[0002] The rocker arm seat is a part that is very similar to a T-shaped part. Before installing the rocker arm seat on mechanical equipment, it is often necessary to process the rocker arm seat first. At present, the processing method of the rocker arm seat is that workers use a milling machine to process it. The rocker arm seat is fixed in the processing position and does not move. The milling cutter rotates and reciprocates in a straight line. When the milling cutter passes through the surface of the rocker arm seat, a processing surface is milled out. Because the rocker arm seat is small in size and the processing cycle of the plane is short, the operation of clamping and fixing the parts is relatively frequent. Workers are prone to make mistakes during operation, resulting in unqualified products. In addition, the operating efficiency of a single worker is low, especially workers with insufficient proficiency have lower processing efficiency per unit time and are prone to produce more defective products, which makes the cost paid by the enterprise higher and the profit lower.

The lifting screw 2 is driven by the lifting motor 23. 1 rotates, so that the lifting beam 22 moves up and down. One side of the lifting is connected to the upper rotating motor seat 2. The positioning part includes a lower rotating motor 6, a fixed round table 7 and a six-station turntable 8. The lower rotating motor seat 6 is fixed on the fixed base 1. The six-station turntable 8 is connected to the output end of the lower rotating motor seat 6. A fixed round table 7 is also provided between the six-station turntable 8 and the lower rotating motor seat 6. The fixed round table 7 is fixed on the fixed base 1. A symmetrical lifting positioning pin 9 is provided on the fixed round table 7. The bottom of the lifting positioning pin 9 is conical. A blind hole groove 10 that penetrates into the bottom of the lifting positioning pin 9 is also provided on the fixed round table 7. A telescopic motor 11 is also provided on one side of the fixed round table 7. A telescopic rod 12 is provided at the output end of the telescopic motor 11. The telescopic rod 1 2 is inserted deep into the blind hole groove 10 on the fixed truncated table 7. The six-station turntable 8 includes a rotating base 13 located in the middle and six station arms 14 with the same structure fixed on the side of the rotating base 13. The rotating base 13 is a regular hexagon, and the middle is a circular shaft hole connected to the output end of the rotating motor on the lower rotating motor seat 6. The end of the station arm 14 away from the rotating base 13 is provided with a rocker seat slot 15, and the end close to the rotating base 13 is provided with a clamping motor 16. A fixed baffle 17 is provided on one side of the rocker seat slot 15, and a push plate 18 is provided on the other side. One side of the push plate 18 is connected to the clamping motor 16, and also includes a safety device, which includes a laser transmitter 19 and a laser receiver 20. The laser transmitter 19 is placed in the processing box 3. The laser receiver 20 is arranged on the inner top of the work station arm 14. The laser receiver 20 is used to control the closing of the power circuit of the lifting mechanism. When the laser receiver 20 receives the laser signal emitted by the laser transmitter 19, the cable of the lifting motor 23 will be connected to the power supply, so as to control the lifting of the lifting motor 23. When the laser receiver 20 cannot receive the laser signal emitted by the laser transmitter 19, the cable of the lifting motor 23 and the power supply will be cut off. The work station arm 14 is located on both sides of a section of the rocker arm seat slot 15. The diameter of the groove 28 matches the diameter of the positioning pin. The provision of the groove 28 can make the lifting positioning pin 9 and the work station arm 14 more stable.

[0023] The working principle of the present invention is as follows: the operator sequentially puts the rocker arm seat into the rocker arm seat groove 28 on the six station arms 14. After filling, the clamping motor 16 on the six station arms 14 is driven to push the push plate 18 to clamp the rocker arm seat, and then the motor on the lower rotating motor seat 6 is driven to drive the rotating base 13 to rotate, so that the six station arms 14 rotate clockwise or counterclockwise on the fixed truncated table 7. The rotation direction is adjusted according to the position of the telescopic motor 11. At the same time, the telescopic motor 11 is driven to drive the telescopic rod 12 to extend. The telescopic rod 12 moves deep into the blind hole groove 10 in the fixed truncated table 7. When it moves to the bottom of the first lifting positioning pin 9, since the bottom of the lifting positioning pin 9 is conical, the telescopic rod 12 is also conical when it penetrates into the blind hole groove 10. The telescopic rod 12 will push the first lifting positioning pin 9 to move upward, and the first positioning pin will protrude from the surface of the fixed truncated table 7. The height of its rise is consistent with the height of the station arm 14. When one of the six station arms 14 rotates to this position, it will be stuck by the first raised lifting positioning pin 9, and at the same time, the telescopic rod 12 continues to move deep into the blind hole groove 10, driving the second lifting positioning pin 9 to rise. The distance between the two lifting positioning pins 9 is equal to the distance between the two hemispherical grooves 28 on the station arm 14. When the second lifting positioning pin 9 is raised, the station arm 14 in between will be firmly stuck. After being stuck, the safety device, that is, the bottom laser receiver 20, is used to detect whether it is in the same position as the processing part on the top. If the position is consistent, that is, the positioning is accurate, the lifting motor 23 can be driven to descend, and the motor in the upper rotating motor seat 2 drives the processing box 3 to rotate. During the rotation process, the processing hob 5 inside the processing box 3 can roll the rocker arm seat. If the lifting motor 23 cannot be driven to descend, the processing part is not aligned with the rocker arm seat, and the equipment needs to be inspected to avoid losses. After processing the first rocker arm seat, the first station arm 14 is released by retracting the telescopic rod 12, and the above steps are repeated to process the following rocker arm seats. After all six are processed, they are disassembled and reloaded. The advantage of this embodiment is that the worker only needs to put the rocker arm seat into the rocker arm seat slot 15 on the six station arms 14 to realize the automatic processing of the rocker arm seat. Multiple rocker arm seats can be processed at one time, which greatly improves the processing efficiency of the rocker arm seat. In addition, the device has no requirements on the number and proficiency of workers. The use of automated processing improves product quality, reduces the unqualified rate of products, and avoids the loss of costs to the enterprise caused by defective products.
