Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, and in particular to a double rocker arm lifting rotary exchanger. Background Technology

[0002] In existing technologies, in automated assembly, switching, and sorting applications, some traditional double-rocker lifting and rotating exchangers are typically operated by two independent mechanisms for lifting and rotation. Most of these devices use multiple pneumatic or hydraulic cylinder groups or motor-driven lead screw groups to achieve lifting and rotation actions. Because pneumatic or hydraulic cylinders are slow to operate and require a sensor switch response before the next action can be performed, their efficiency is low. Furthermore, when the motor-driven lead screw operates, the motor needs to alternate between forward and reverse rotation, which makes it impossible to guarantee transmission accuracy. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a double-rocker lifting rotary exchanger.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A double rocker arm lifting rotary exchanger includes a housing, inside which a turret is provided. The top of the turret is connected to the output sleeve, and multiple turret rollers are distributed in the middle. Any pair of turret rollers is in contact with the outer wall of the lifting rotary cam. The lifting rotary cam is coaxially mounted on the inner wall of the housing via a camshaft. Rocker arms are rotatably provided on both sides away from the lifting rotary cam. Each rocker arm has a rocker arm roller on its inner side, which is embedded in a flat groove opened in the side wall of the lifting rotary cam. One end of the rocker arm is matched with the output sleeve through the output sleeve roller. When the lifting rotary cam rotates, the rocker arm is guided by the flat groove to make a deflection movement and push the output sleeve to make a lifting movement.

[0005] In addition, a preferred structure is that a turret mounting base is fixedly installed on one side of the inside of the housing, a turret is mounted on the upper part of the turret mounting base, multiple turret rollers are evenly distributed along the circumference on the outer wall of the middle part of the turret, and the top of the turret is connected and matched with the output sleeve adapter plate through the output sleeve, and the output sleeve adapter plate is installed in the output sleeve mounting base set on the upper wall of the housing.

[0006] Furthermore, in a preferred configuration, the two side walls of the lifting rotary cam are provided with cam-shaped planar grooves, and rocker arm rollers are slidably fitted within the cam-shaped planar grooves.

[0007] In addition, a preferred structure is that the inner wall of the output sleeve fixing seat is provided with a TC oil seal, a self-lubricating bearing, and a bearing cap from top to bottom.

[0008] The beneficial effects of this utility model are as follows: In this invention, the lifting rotary cam rotates to drive the turret to rotate and the rocker arm to swing. The rocker arm swing drives the output sleeve mounted on the turret to perform axial lifting, thereby enabling the output sleeve mechanism to achieve synchronous rotation and lifting movements. The structure has a high degree of integration and does not require separate rotation and lifting mechanisms, nor does it rely on external induction switches. It has a fast response and reliable operation. Attached Figure Description

The housing assembly 1 includes a housing 11 as the main body. The lifting assembly 3 is provided on one side of the interior of the housing 11. One end of the lifting assembly 3 is linked and matched with the rotating assembly 2. Furthermore, the rotating assembly 2 includes a lifting rotating cam 23, a turret 24, and a turret fixing seat 28, and the lifting assembly 3 includes a rocker arm 32, a rocker arm roller 33, and an output sleeve 36; A turret mounting base 28 is fixedly installed on one side of the interior of the housing 11. A turret 24 is rotatably mounted on the upper part of the turret mounting base 28. Multiple turret rollers 25 are evenly distributed along the circumference of the outer wall of the middle part of the turret 24. The top of the turret 24 is connected to the output sleeve 36 through a square or spline structure. The output sleeve 36 is connected and matched with the output sleeve adapter plate 37. The output sleeve adapter plate 37 is installed in the output sleeve mounting base 13 set on the upper wall of the housing 11. In addition, a VK end cap is provided on one side of the bottom of the housing 11.

[0013] Furthermore, the turret 24 is partially equipped with multiple turret rollers 25, and any pair of turret rollers 25 is in contact with the outer wall of the lifting rotary cam 23. The lifting rotary cam 23 is rotatably mounted on the inner wall of the housing 11 via the camshaft 21. When the lifting rotary cam 23 rotates, it will drive the turret rollers 25 to achieve the rotational movement of the turret 24 and the output sleeve 36.

[0014] Furthermore, the two eccentric sleeves 221 are fixed to the housing 11 and the side cover 12 respectively by screws. The adjusting nut 222 is screwed into the eccentric sleeve 221 with external threads and is tightly pressed against the outer ring of the tapered roller bearing 223. The outer ring of the tapered roller bearing 223 is pressed into the eccentric sleeve 221, and the inner ring is pressed into the lifting rotary cam 23. The lifting rotary cam 23 is sleeved on the camshaft 21. The adjusting nuts 222 on both sides are tightened to press the tapered roller bearing 223 and the lifting rotary cam 23 together. One end of the turret roller 25 is hammered into the turret 24 and secured with a set screw on the side. The turret mounting base 28 is screwed onto the housing 11. The outer rings of two tapered roller bearings 26 are pressed into the turret mounting base 28, and the inner rings are fitted onto the turret 24. The locking nut 27 engages with the threads on the turret 24, so that the turret 24 can only rotate on the turret mounting base 28.

[0015] Rocker arms 32 are rotatably provided on both sides away from the lifting rotary cam 23. One end of the rocker arm 32 is rotatably connected to the rocker arm fixing seat 311. The rocker arm fixing seat 311 is screwed onto the housing 11 and the housing cover 12 respectively. The rocker arm 32 is equipped with a needle roller bearing 313, and thrust bearings 312 are placed on both sides. The rocker arm shaft core 314 and the rocker arm fixing seat 311 clamp the rocker arm 32 with threads. Another screw is locked between the rocker arm shaft core 314 and the rocker arm fixing seat 311 to prevent loosening. The rocker arm roller 33 is pressed into the rocker arm 32 and fastened to the rocker arm 32 by the anti-loosening nut 34. The output sleeve roller 35 is hammered into the rocker arm 32 and tightened by the side set screw.

[0016] Each rocker arm 32 has a rocker arm roller 33 on its inner side, which is embedded in a flat groove opened in the side wall of the lifting rotary cam 23. One end of the rocker arm 32 is engaged with the output sleeve 36 through the output sleeve roller 35. When the lifting rotary cam 23 rotates, the rocker arm 32 is guided by the flat groove to make a deflection movement and push the output sleeve 36 to make a lifting movement.

[0017] The lifting rotary cam 23 has cam-shaped planar grooves on both sides, and rocker arm rollers 33 slide within the cam-shaped planar grooves.

[0018] The inner wall of the output sleeve fixing seat 13 is provided with a TC oil seal 14, a self-lubricating bearing 15, and a bearing cover 16 from top to bottom to ensure the rotational stability of the output sleeve 36.

[0019] In this embodiment, the camshaft 21 drives the lifting rotary cam 23 to rotate. The lifting rotary cam 23 engages with the turret roller 25 on the turret 24 through the continuous groove opened on its end face, thereby driving the turret 24 to rotate.

[0020] Meanwhile, the flat groove on the side wall of the lifting rotary cam 23 cooperates with the rocker arm roller 33 to convert the rotational motion of the cam into the swinging motion of the rocker arm 32 around its support shaft. The output sleeve 36, which is mounted on the turret 24, is driven by the output sleeve roller 35 at the end of the rocker arm 32 to generate an axial lifting motion. In conjunction with the rotational motion of the turret 24, the output sleeve 36 and its connected output sleeve adapter 37 realize the rotation and lifting motion.

[0021] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
