Description

Technical Field

[0001] The utility model belongs to the technical field of automatic feeding and automatic pressing, and particularly relates to a bowl plug pressing floating mechanism. Background Technique

[0002] In the original method, the bowl plug was taken by hand and placed at the front end of the pressing hole, and the pressing machine was manually operated to press the bowl plug into the product hole. Because of the need for position coordination, automatic production could not be achieved, the efficiency was low and the hand was easily injured. Considering automatic installation, the pressing machine and the product hole could not ensure that they could be completely aligned and pressed every time. Once offset, the product might be damaged. Therefore, a floating head automatic pressing was developed. Content of the Utility Model

[0003] In order to solve the defects existing in the prior art, a bowl plug pressing floating mechanism is provided, which includes a driving device, a pressing rod and a floating joint. The driving device is arranged on the servo motor mounting frame. The driving device is connected with the pressing rod through the floating joint. The pressing rod is installed inside the guide sleeve and can slide back and forth in the guide sleeve. The guide sleeve is arranged on the guide sleeve mounting seat. The guide sleeve mounting seat is fixed on the servo motor mounting frame through the support column. The front end of the pressing rod is connected with the floating head through a limit pin. One O-ring is installed in front of and behind the limit pin. The floating head is sleeved on the outer diameter of the front end of the pressing rod through the limit pin. The front end of the floating head sucks the bowl plug through a magnet, and the bowl plug is pressed into the hole of the automotive engine cast aluminum part through the driving device.

[0004] Further, the driving device includes a servo motor, an electric cylinder and a synchronous belt wheel drive box. The servo motor is connected with the electric cylinder through the synchronous belt wheel drive box.

[0005] Further, the electric cylinder is arranged on the servo motor mounting frame.

[0006] Further, the bowl plug and the hole of the cast aluminum part are tightly fitted and connected.

[0007] Further, a clearance section for floating is arranged in the diameter direction of the front end of the floating head and the pressing rod.

[0008] The beneficial effects of the utility model are as follows: The utility model uses a servo electric cylinder as the power, and the front end cooperates with the floating head to suck the workpiece for pressing, effectively ensuring the pressing depth and the success rate of pressing. The pressing torque is fed back through the servo electric cylinder. The torque and depth ensure the qualification of the product pressing. When there is no pressing, there is no torque. When the torque exceeds the standard, it means that the pressing is offset. When the stroke feedback of the servo electric cylinder is abnormal, it means that the pressing depth is incorrect. Thus, the controllability and feedback of the whole pressing process are ensured, and it is applicable to any occasion of precision pressing, such as the pressing of automotive brake bearings, the pressing of wheels, etc., ensuring the installation quality and consistency; it is convenient, fast, time-saving and labor-saving.

[0016] A bowl plug pressing-in floating mechanism, as Figures 1 - 6 shown, comprises a driving device, a pressing-in rod 8 and a floating joint 9. The driving device is arranged on the servo motor mounting bracket 11. The driving device is connected to the pressing-in rod 8 through the floating joint 9. The pressing-in rod 8 is installed inside the guide sleeve 7 and can slide back and forth in the guide sleeve 7. The guide sleeve 7 is arranged on the guide sleeve mounting seat 10. The guide sleeve mounting seat 10 is fixed on the servo motor mounting bracket 11 through the support column 5. The front end of the pressing-in rod 8 is connected to the floating head 2 through the limit pin 3. One O-ring 4 is installed on each of the front and rear sides of the limit pin 3. The floating head 2 is sleeved on the outer diameter of the front end of the pressing-in rod 8 through the limit pin 3. The front end of the floating head 2 sucks the bowl plug 1 through a magnet. The bowl plug 1 is pressed into the hole of the automotive engine cast aluminum part through the driving device.

[0017] Wherein, the driving device comprises a servo motor 6, an electric cylinder 12 and a synchronous belt pulley drive box 13. The servo motor 6 is connected to the electric cylinder 12 through the synchronous belt pulley drive box 13.

[0018] Wherein, the electric cylinder 12 is arranged on the servo motor mounting bracket 11.

[0019] Among them, the bowl plug 1 is tightly and fittingly connected to the hole of the cast aluminum part.

[0020] Among them, a clearance section 21 for floating is arranged in the diameter direction at the front end of the floating head 2 and the pressing rod 8.

[0021] The utility model is used to accurately press the bowl plug 1 into the hole of the cast aluminum part of the automobile engine and maintain a precise fit. The servo motor 6 and the electric cylinder 12 are connected and powered through the synchronous pulley drive box 13. This combined mechanism is installed on the servo motor mounting bracket 11 and then fixed to a workbench. The electric cylinder 12 and the pressing rod 8 are connected through the floating joint 9. The pressing rod 8 is installed inside the guide sleeve 7 and can slide back and forth in the guide sleeve 7. The guide sleeve 7 is installed on the guide sleeve mounting seat 10. The guide sleeve mounting seat 10 is fixed to the entire servo motor mounting bracket 11 through the support column 5. The floating head 2 and the pressing rod 8 are connected through the limit pin 3 at the front end of the pressing rod 8. One O-ring 4 is installed on each of the front and rear sides of the limit pin 3, so as to ensure a certain clearance in the diameter direction at the front end of the floating head 2 and the pressing rod 8 for floating. The bowl plug 1 is sucked by the magnet at the front end of the floating head 2 each time and is pressed into the cast aluminum under the action of the servo electric cylinder 12. Since the bowl plug 1 and the hole of the cast aluminum part are tightly fitted, the front floating head improves the pressing success rate in the case where the coaxiality cannot be accurately guaranteed.

[0022] The utility model uses a servo electric cylinder as the power, and the front end cooperates with a floating head to suck the workpiece for pressing, effectively ensuring the pressing depth and the pressing success rate. The pressing torque is fed back by the servo electric cylinder. The torque and the depth ensure the qualification of the product pressing. When there is no pressing, there is no torque. When the torque exceeds the standard, it means that the pressing is off. When the stroke feedback of the servo electric cylinder is abnormal, it means that the pressing depth is incorrect, thus ensuring the controllability and feedback of the entire pressing process. It is applicable to any precision pressing occasion, such as the pressing of automobile brake bearings, the pressing of wheel hubs, etc., ensuring the installation quality and consistency; achieving convenience, speed, time saving and labor saving.

[0023] The above is only the preferred embodiment of the utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the utility model.
