Description

Technical Field

[0001] The invention relates to an automatic assembly mechanism, in particular to an automatic assembly mechanism for a divider housing cover. Background Art

[0002] Dividers, also commonly known as intermittent dividers, are mostly used in automation equipment to achieve intermittent rotation transmission.

[0003] The cam divider is a mechanism for achieving intermittent motion. It has the following remarkable features: high indexing accuracy, smooth operation, large torque transmission, self-locking during positioning, compact structure, small size, low noise, good high-speed performance, and long life. It is an ideal product to replace traditional mechanisms such as grooved wheel mechanisms, ratchet mechanisms, incomplete gear mechanisms, and pneumatic control mechanisms.

[0004] During the assembly process of the divider, after the installation of the cam, turret, cam roller and shaft is completed, lubricating oil needs to be injected and the cover needs to be sealed at the opening.

[0005] The existing cap assembly operation is all manual operation, specifically, manually holding a hammer to place the cap in the through hole and then gradually knock it in. Due to the sealing requirement, the outer diameter of the cap and the inner diameter of the through hole are interference fit, so it is difficult to assemble in place, and it is necessary to knock along the edge of the cap several times to achieve assembly.

[0006] However, when holding a hammer to knock, only one point can be knocked at a time, and the cap cannot be evenly stressed. Therefore, the cap often becomes crooked, making it impossible to continue knocking it in and difficult to take it out. In addition, continuous manual knocking will undoubtedly consume more manpower and cause arm fatigue and soreness. Summary of the invention

[0007] The objects of the present invention are:

[0008] Provided is a divider shell cover automatic assembly mechanism, which can suck and hold the cover workpiece and adjust its posture, place the cover in a through hole on the divider shell and press it in evenly to achieve assembly, and can perform inspection after assembly is completed, thereby reducing manual labor intensity and improving cover assembly accuracy.

[0009] In order to achieve the above object, the present invention provides the following technical solutions:

[0010] A divider shell cover automatic assembly mechanism comprises a frame, and also includes an oil cylinder, a lifting plate, a pressure rod, a contact ring, a cylinder and a suction cup; the oil cylinder is located at the top of the frame, the lifting plate is connected to the bottom end of the piston rod of the oil cylinder through a connecting frame, the pressure rod is vertically arranged at the lower end of the lifting plate, and the pressure rods are arranged in a circular array relative to the piston rod of the oil cylinder; the bottom end surface of the lifting plate is also provided with an inner ring distance sensor and an outer ring distance sensor, and the detection ends of the inner ring distance sensor and the outer ring distance sensor are both vertically downward; the contact ring is connected to the bottom end of the lifting plate through an elastic pin; the cylinder is located on the lifting plate, and the suction cup is connected to the suction cup seat at the bottom end of the piston rod of the cylinder through an air pipe, and the suction cup is located on the inner side of the contact ring.

[0011] Furthermore, the oil cylinder is arranged vertically; the connecting frame is in an inverted U shape; the lifting plate is in a disc shape, and a guide rod is arranged on the top of the lifting plate, and the guide rod passes through the frame and is movably connected to the bushing on the frame.

[0012] Furthermore, the number of the inner ring distance sensors is multiple and they are arranged in a circular array relative to the piston rod of the oil cylinder; the number of the outer ring distance sensors is multiple and they are arranged in a circular array relative to the piston rod of the oil cylinder.

[0013] Furthermore, the inner ring distance sensor is located on the side of the pressure rod facing the center of the lifting plate; and the outer ring distance sensor is located on the side of the pressure rod facing the edge of the lifting plate.

[0014] Furthermore, the abutment ring is annular and is coaxially arranged with the piston rod of the oil cylinder; the abutment ring is made of rubber; and the elastic pins are arranged in a circular array along the abutment ring.

[0015] Furthermore, the cylinder is arranged vertically, and the cylinder body of the cylinder is connected to the top surface of the lifting plate; and an air pipe joint is arranged on the suction cup seat.

[0016] Furthermore, the opening of the suction cup faces downward, and the suction cup is specifically located at the center of the abutment ring.

The suction cup can hold the cover workpiece, and the resistance ring can adjust the posture. Then the cover is placed in the through hole on the divider shell, the oil cylinder is actuated, and multiple pressure rods are evenly pressed in to achieve assembly. At the same time, the inner ring distance sensor and the outer ring distance sensor can be tested after the assembly is completed, replacing the original manual hand-held hammer to knock, which can greatly reduce the labor intensity of human labor, save labor costs, avoid the situation where the cover is skewed and cannot be knocked in and is difficult to take out, and improve the cover assembly accuracy.
