Example 2

This embodiment is an improvement made on the basis of the embodiment 1. Specifically, please refer to FIGS. 1 to 8 . A tightening frame 7 is provided at the top of the lifting inner shaft 42. The tightening frame 7 includes a movable groove 71, a driving groove 72, a driving rod 73, a pushing block 74 and an inner supporting platform 75. The top of the lifting inner shaft 42 is provided with an inner supporting platform 75. The inner part of the inner supporting platform 75 has movable grooves 71 in a circular array. The inner part of the movable groove 71 is provided with a driving groove 72. The inner part of the driving groove 72 is movably installed with a driving rod 73. One end of the driving rod 73 is provided with a pushing block 74.

A plurality of push blocks 74 are combined to form an annular ring, and the annular ring is used to provide a shrinking and fixing environment for the workpiece;

The inner lifting shaft 42 is provided with a driving structure 8, which includes an oil delivery groove 81, a piston 82 and a slit groove 83. The outer side of the inner lifting shaft 42 is provided with a piston 82 located in the supporting main shaft 41, and the inner part of the piston 82 is provided with a slit groove 83. The axis of the inner lifting shaft 42 is provided with an oil delivery groove 81, and the inner part of the piston 82 is provided with a hole groove, and the oil delivery groove 81 is used to communicate with the hole groove;

The driving structure 8 further includes a connecting groove 84, an inner flow channel 85 and a spring 86. The inner side of the supporting main shaft 41 is provided with a connecting groove 84, and the top end of the lifting inner shaft 42 is provided with an inner flow channel 85 located below the driving groove 72. The inner flow channel 85 is used to communicate with the driving groove 72.

A spring 86 is installed at one end of the driving slot 72 , and the spring 86 is used to provide a restoring force for the driving rod 73 .

The working principle of the driving structure 8 and the tightening frame 7 is as follows: the hydraulic cylinder 9 provides oil power to the interior of the supporting main shaft 41. First, the oil is transported to the cavity below the piston 82 through the pipeline. When the internal pressure increases, an upward force is provided to the piston 82, and the lifting inner shaft 42 is driven to rise as a whole, and the inner support platform 75 is driven to rise together. When the piston 82 rises to one side of the connecting groove 84, and the outer side of the gap groove 83 is connected to the upper end interface of the connecting groove 84, the pressure inside the connecting groove 84 is less than the pressure of the cavity below the piston 82.

At this time, the oil below the piston 82 will flow into the connecting groove 84, and then flow into the interior of the slit groove 83, and then enter the interior of the oil delivery groove 81 through the hole groove inside the slit groove 83, and then flow into the inner flow channel 85 from the interior of the oil delivery groove 81;

Finally, the inner flow channel 85 enters the interior of the driving groove 72, and the increase in the internal pressure of the driving groove 72 drives the driving rod 73 to retract, and provides a force for the driving groove 72 to retract inward, driving the push block 74 to move. Through the overall retraction of the annular ring, the fixing function of the welded part can be achieved, and it is ensured that when the device is flipped, a fixing force is provided to the welded part, thereby increasing the stability during welding.

Example 3

This embodiment is an improvement made on the basis of the embodiment 2. Specifically, please refer to FIGS. 1 to 8 . A control computer 11 is fixedly mounted on the outer side of the base housing 1. A bracket is provided on one side of the control computer 11. A visual sensor 12 is movably mounted on the top of the bracket. Infrared sensors 13 are arranged in a ring shape on the outer side of the base housing 1. The infrared sensors 13 and the encoder 58 are electrically connected to the control computer 11.

An annular frame is also provided on the lower surface of the placement platform 21 , a hydraulic cylinder 9 is installed on one side of the annular frame, and an oil tank is fixedly installed on the other side of the annular frame. The hydraulic cylinder 9 is used to provide oil pressure for lifting the inner shaft 42 .

In some special environments, forklifts are usually used or manual handling is still performed to place welded parts on the equipment;

When a worker carrying a welded part approaches the device, the hydraulic cylinder 9 identifies the surroundings. After recognizing that a forklift is approaching, the device as a whole starts to operate, and the annular detection circle formed by multiple infrared sensors 13 on the outside of the base shell 1 detects the approaching worker again, and detects where the worker is coming from in a more specific position, and sends information to the control computer 11, which then processes and judges, and provides the required movement instructions to the encoder 58;

At this time, the first threaded shaft 53 and the second threaded shaft 54 provide power output to the transverse slide bar 52, driving the connecting ball pin 44 to move, so that the moving position of the connecting ball pin 44 is opposite to the direction of the welded part, so that the flip platform 31 is inclined to the direction where the manual work is coming, so that the flip platform 31 has a certain tilt angle, which is convenient for manual work when placing, and is convenient for the clamping and fixing of the workpiece. Before this, the inner support platform 75 is driven by the hydraulic cylinder 9 to rise as a whole. When it rises to a certain height, it stops rising. At this time, the manual workpiece is placed on the upper surface of the inner support platform 75. After the installation is completed, the inner support platform 75 continues to rise, and provides contraction power to the push block 74, and clamps the welded part therein, completing the fixing operation of the welded part. At this time, the flip platform 31 returns to a horizontal state to wait for welding work;

This method is to ensure that when workers place welded parts on a wider table, the table can be tilted to facilitate the placement of the workpieces. It can also be tilted in the corresponding direction according to the position of the workers, thereby realizing the function of intelligent angle adjustment and ensuring the angle adjustment when the workpiece is placed.

When in use, the transverse slide bar 52 is embedded in the outer side of the limiting convex edge 63, and the limiting edge 70 is inserted into the inner side of the positioning edge groove 65. The support roller 64 is a stepped structure, so that the outer side of the support roller 64 can be stuck in the inner side of the limiting edge 70 and fit with the two ends of the inner wall of the transverse slide bar 52, so as to provide the transverse slide bar 52 with a limited stabilization effect while providing the sliding of the transverse slide bar 52;

By buckling the connecting ball pin 44 on the upper surface of the positioning pin ball 67, the connecting ball pin 44 can slide around the outer surface of the positioning pin ball 67, and by the threaded fixing method of the limiting cover 68 and the outer side of the movable sleeve 62, the limiting cover 68 is pressed down from the top of the connecting ball pin 44, and a limiting effect is provided to the connecting ball pin 44, so that the connecting ball pin 44 is limited in the movable cavity 69, so that it can move at multiple angles in a specified area, and the connecting ball pin 44 is buckled on the upper surface of the positioning pin ball 67, so that the device has a multi-angle adjustment function, and at this time, the upper side of the connecting ball pin 44 is fixed by the limiting cover 68, and fixed to the outer side of the movable sleeve 62, so that the connecting ball pin 44 and the movable sleeve 62 are provided with a fixation, and also have a multi-angle movement adjustment function, so that the connection strength of the device is higher, and it is used in conjunction with the upper end support component, so that when the connecting ball pin 44 is matched with the positioning pin ball 67, the support strength can be significantly increased, and finally the support ball 66 contacts the bottom surface of the lower end to provide a support effect;

When the push block 74 is initially in contact with the device, the push block 74 is supported by the driving rod 73, and the contraction force provided is relatively fast, resulting in a collision when contacting with the workpiece, which affects the outer surface quality of the device;

When the driving rod 73 contracts and drives the pushing block 74 to retract, through the supporting effect of the supporting inner rod 77, when the pushing block 74 contracts and contacts the outer surface of the workpiece, the driving rod 73 will continue to pull, so that the supporting inner rod 77 is located inside the driving rod 73 to achieve relative movement. At this time, the area inside the buffer cavity 76 and the area at one end of the supporting inner rod 77 is half filled with oil, and the oil mixed with gas is located inside the buffer cavity 76, which will provide expansion and contraction resistance when the supporting inner rod 77 moves, so that when the pushing block 74 contacts the outer surface of the workpiece, it provides a buffering effect and provides a collision protection effect for the workpiece during initial clamping.
