In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/", and generally means that the former and latter related objects are in an "or" relationship.

The auxiliary assembly tool provided in the embodiments of the present application is described in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

As shown in fig. 1 to 2, the embodiment of the present application provides an auxiliary assembly tool for assembling an engine, but may also be used for assembling other structures, and is not limited in particular here. The auxiliary assembly tool includes a bracket 100, a valve slapping assembly 200, and a drive mechanism 300. Alternatively, the auxiliary assembly tool may be provided on a robot or other mobile device to facilitate movement.

The valve slapping assembly 200 includes a slapping lever 210 and a swing mechanism 220, the swing mechanism 220 is disposed on the frame 100, the swing mechanism 220 is located below the frame 100, the swing mechanism 220 is connected to a first end of the slapping lever 210, and the swing mechanism 220 can rotate relative to the frame 100 to adjust the position of the slapping lever 210. Because the valve arrangement modes of different types of engines are different, or the valve arrangement modes of different cylinders of the same engine are different, when the auxiliary assembly tool drives the patting rod 210 to move above the valve, a certain position deviation may exist between the patting rod 210 and the valve, and at this time, the swing mechanism 220 rotates to adjust the relative position of the patting rod 210 and the valve.

The driving mechanism 300 is disposed on the bracket 100, the driving mechanism 300 is connected to the swing mechanism 220, and the driving mechanism 300 drives the patting bar 210 to reciprocate through the swing mechanism 220, so that the second end of the patting bar 210 repeatedly patts the valve of the engine.

In the embodiment of the application, after the valve assembly of the engine is mounted, the moving device moves the auxiliary assembling tool to the tapping position of the valve, the rotating mechanism 220 rotates relative to the bracket 100 to adjust the position of the tapping rod 210, so that the tapping rod 210 is opposite to the valve, then the whole auxiliary assembling tool is lowered to the second end of the tapping rod 210 to be pressed on the end surface of the valve of the engine, the driving mechanism 300 drives the tapping rod 210 to reciprocate through the rotating mechanism 220, so that the second end of the tapping rod 210 taps the valve of the engine repeatedly, thereby achieving the purpose of tapping the valve automatically, and further improving the assembling efficiency of the engine. Therefore, the problem that the assembly efficiency of the existing engine is low can be solved.

In an alternative embodiment, the revolving mechanism 220 includes a revolving cylinder 221 and a revolving disc 222, the revolving cylinder 221 is disposed on the support 100, an output end of the revolving cylinder 221 is connected to the revolving disc 222, a first end of the tapping rod 210 is connected to the revolving disc 222, the revolving cylinder 221 and the tapping rod 210 are respectively disposed on two opposite sides of the revolving disc 222, and the output end drives the tapping rod 210 to rotate through the revolving disc 222 to adjust the position of the tapping rod 210. Optionally, due to the characteristic of stable operation of the revolving cylinder 221, the rotation position of the revolving disc 222 can be precisely controlled, so that the relative position between the tapping rod 210 and the valve can be precisely adjusted, which is beneficial to improving the tapping efficiency of the tapping rod 210. Of course, the rotary disk 222 may be driven by other driving sources, such as a motor, etc., but the motor does not drive the rotary disk 222 to rotate as well as the rotary cylinder 221.

The revolving cylinder 221 may be directly connected to the driving mechanism 300, but during the driving mechanism 300 drives the revolving mechanism 220 to reciprocate, the revolving cylinder 221 acts on the support 100, which may easily cause the bottom wall 110 of the support 100 to deform. Therefore, optionally, the turning mechanism 220 further comprises a connecting member 223, the connecting member 223 is connected between the driving mechanism 300 and the turning cylinder 221, namely, the connecting member 223 is located between the support 100 and the turning cylinder 221, the connecting member 223 acts on the bottom surface of the support 100 during the reciprocating motion of the turning mechanism 220 driven by the driving mechanism 300, the contact area between the connecting member 223 and the bottom surface of the support 100 is large, so that the acting force between the connecting member 223 and the bottom surface of the support 100 can be dispersed, the protection of the support 100 is facilitated, and the area of the surface of the connecting member 223 facing the turning cylinder 221 is large, so as to facilitate the arrangement of the turning cylinder 221.

In the process that the driving mechanism 300 drives the patting bar 210 to reciprocate through the swing mechanism 220, when the connection member 223 comes into contact with the bottom surface of the support 100, the swing cylinder 221 is easily damaged by the force of the swing plate 222 acting on the output end of the swing cylinder 221 at this time due to the tendency of the inertia of the swing plate 222 to move further. Based on this, further optionally, the revolving mechanism 220 further comprises a support 224, the support 224 is supported between the connecting member 223 and the revolving disk 222, the support 224 is in sliding fit with the revolving disk 222, and the revolving disk 222 can slide around its own rotation axis relative to the support 224. When the connecting member 223 contacts the bottom surface of the bracket 100, the supporting member 224 prevents the rotation disk 222 from further moving, thereby protecting the rotation cylinder 221.

After the tapping rod 210 finishes tapping, the robot or the mobile device drives the auxiliary assembly tool to integrally lift, at this time, because the port of the second end of the sealing sleeve 410 is in sealing fit with the upper seat of the valve spring of the engine, the sealing sleeve 410 is kept still, and after the tapping rod 210 moves to be separated from the valve of the engine, a sealing cavity is formed among the upper seat of the valve spring, the sealing sleeve 410 and the tapping rod 210, at this time, high-pressure gas is continuously introduced into the sealing cavity through the pneumatic connector 430, if the flow of the introduced high-pressure gas is small, it is indicated that the valve collet of the engine is installed in place, and the gap between the valve collet and the valve and the upper seat of the valve spring is small, so that the technical requirements are met; if the high-pressure gas flow is large, the valve collet is not installed in place, the clearance between the valve collet and the valve and between the valve collet and the upper seat of the valve spring is large, and at the moment, an alarm can be given out through the detection result of the flow sensor so as to inform manual processing.

At actuating mechanism 300 drive camshaft 500 pivoted in-process, first gyro wheel 600 is rolling fit with camshaft 500's eccentric wheel all the time, and the distance between eccentric wheel and camshaft 500's the pivot is nearer, and the camshaft 500's that makes structure is comparatively compact and the reliability is better, so actuating mechanism 300 drives through this kind of mode and beats pole 210 and carry out reciprocating motion, is favorable to improving the motion stability who beats pole 210, can also improve auxiliary assembly tool's compact structure nature simultaneously.

In a further alternative embodiment, the auxiliary assembly tool further includes a guide shaft 900, the bottom wall 110 is provided with a guide hole, one end of the guide shaft 900 is connected to the swing mechanism 220, and the guide shaft 900 is in guiding fit with the guide hole, so as to provide a motion guide for the reciprocating motion of the swing mechanism 220 and avoid the flapping rod 210 from being misaligned with the valve due to the tilting of the swing mechanism 220. Alternatively, the other end of the guide shaft 900 may have a second stopper portion, and when the tapping lever 210 is in contact with the valve, the second stopper portion may prevent the swing mechanism 220 and the tapping lever 210 from further descending to protect the valve.
