Description

Technical Field

[0001] The present invention relates to the field of piston assembly, and in particular to a multi-station assembly workstation. Background Art

[0002] The piston is a mechanical part that reciprocates along the cylinder axis in the cylinder of reciprocating piston internal combustion engines, compressors, pumps and other machines. Pistons are available in three forms: disc-shaped, cylindrical and cylindrical. During the assembly process, semi-circular bead gaskets of corresponding sizes need to be placed in the grooves above and below the piston.

[0027] Embodiment 1:

[0028] A multi-station combined workstation, as shown in the figure, includes a feeding unit 100 arranged on the top of a discharging station 1 and an assembly station 2. The feeding unit 100 has X-axis and Y-axis degrees of freedom under the action of a power component 200.

[0029] A sensor 3 is arranged below the discharge station 1, and the sensor 3 is aligned with the assembly station 2, for detecting whether a piston has reached the assembly station 2; the semicircular beads are loaded through the loading port, and the semicircular beads at the discharge port are transferred through the feeding unit 100.

[0030] Specifically, when a piston arrives at the assembly station 2, the feeding unit 100 will transfer the semicircular beads from the discharge station 1 to the assembly station 2.

[0031] In this solution, the feeding unit 100 provided moves between the discharging station 1 and the assembly station 2 through the signal sent by the sensor 3, and realizes the loading, feeding and assembly of the semi-circular beads through automated integration.

[0032] In this embodiment, the sensor 3 is a proximity sensor.

[0033] The feeding unit 100 has a feeding track 110 which is slidably connected to a vacuum machine 120 and a mechanical arm 130 at the bottom.

[0034] The feeding track 110 is fixed on the first connecting plate 101 , and a screw rod 140 connected to the first power structure 210 is arranged in the middle, and a driving end 150 is sleeved in the middle of the screw rod 140 .

[0035] The feeding track 110 is provided with a slide plate 112 which is slidably connected to the second connecting plate 111 , and the vacuum machine 120 and the robot arm 130 are fixed on the slide plate 112 .

[0036] The top of the first connecting plate 101 includes a limiting plate 161 for limiting the rolling chain 160 . The other end of the rolling chain 160 is fixed on a bracket, and the bracket is fixed on the second connecting plate 111 .

[0037] The rolling chain 160 provided in this solution increases the stability of the feeding unit 100 and makes the structure more solid.

[0038] In this embodiment, the first power structure 210 is a motor, which controls the driving end 150 to move along the X-axis.

[0039] Specifically, the first power structure 210 starts after receiving the signal, and controls the first power structure 210 to drive the screw 140 to rotate while the driving end 150 on the screw 140 starts to move, and stops when it moves to a specified position.

[0040] In this embodiment, two vacuum machines 120 are provided, and the suction and release of each robot arm 130 are controlled independently.

[0041] In this solution, two robot arms 130 are provided in the solution to control and move the semicircular beads to the assembly station 2, and put the semicircular beads into the forward track and the reverse track respectively to complete the assembly process.

[0042] The robotic arm 130 includes a second power structure 220 fixed on the second connecting plate 111, the working end of the second power structure 220 is connected to a fixing member to limit and vertically fix the third power structure 230, the bottom of the third power structure 230 is connected to a bracket for fixing the suction cup 131, and the suction cup 131 has the ability to move in the X-axis and Y-axis.

[0043] In this embodiment, the second power structure 220 and the third power structure 230 are both cylinders, which control the suction cup 131 to move along the X-axis and the Y-axis.

[0044] Specifically, the sensor 3 sends a signal to control the third power structure 230 to move along the Y axis toward the material taking port until it fits the semicircular bead, the suction cup 131 sucks the semicircular bead away from the material discharging station 1 through the vacuum machine 120, and the third power structure 230 is reset;

[0045] The second power structure 220 moves along the X-axis toward the assembly station 2 until the semicircular ball at the bottom of the suction cup 131 is aligned with the assembly station 2 , and the suction cup 131 places the semicircular ball into the assembly station 2 under the control of the vacuum machine 120 .

[0046] Assembly station 2, after the semicircular balls enter assembly station 2, the semicircular balls are filled into the upper and lower positions of the piston through the work of this station.

[0047] In summary, the feeding unit provided in the present application moves between the discharging station and the assembly station through the signal sent by the sensor, and realizes the loading, feeding and assembly of semi-circular beads through automated integration.
