The qualified tolerance range of the spacing data is stored in the automatic assembly controller. If it is within the qualified tolerance range, the size is judged to be qualified.

When the O-ring push cylinder is actuated, the O-ring push ring is driven to move up and down on the outer wall of the O-ring installation head assembly, and the O-ring mounted on the O-ring installation head assembly is pushed down to the O-ring installation position of the valve pump body to be press-fitted.

[0017] Optionally, when the automatic assembly controller controls the movement of the O-ring transfer linear slide, the O-ring picking and placing mechanism of the opening station of the O-ring transfer assembly moves between the O-ring material rack assembly and the O-ring opening assembly, and the O-ring installation head assembly moves between the O-ring opening assembly and the valve pump body positioning tooling.

[0018] By adopting the above technical solution, the O-ring automatic assembly mechanism adopts a three-station design, the O-ring transfer assembly can realize the transfer between the three stations, the O-ring rack assembly can adopt a structural form of multiple rack rods on a turntable, multiple O-rings are placed in a stacked form on the multiple rack rods, and a lifting mechanism is set at the bottom.

The press-fitting servo electric cylinder provides a set press-fitting force. When the press-fitting force and the set press-fitting displacement reach the set values, it is considered that the press-fitting meets the requirements.

The motor bolt locking mechanism uses a lifting mechanism to drive multiple electric bolt guns to perform automatic locking operations. In normal conditions, the lifting mechanism is in a retracted state.

[0024] By adopting the above technical solution, the press-fit detection component is mainly based on the dimensional detection from the end of the motor camshaft to the valve pump body processing surface after the press-fitting is completed. This dimension can ensure the smooth assembly of the subsequent connecting rod within the set tolerance range.

[0025] Optionally, the automatic assembly controller is a programmable controller, an industrial computer or a single chip microcomputer.

When the motor cam shaft is oriented, the longitudinal dimension of the drive motor 101 to be pressed is measured. The valve pump body O-ring assembly component includes a valve pump body positioning tool and an O-ring automatic assembly mechanism. The valve pump body positioning tool and the O-ring automatic assembly mechanism are respectively installed on the frame 100, and are used to position the valve pump body 102 to be pressed. The O-ring automatic assembly mechanism is used to assemble the O-ring to the O-ring installation position of the valve pump body 102 to be pressed. The drive motor pressing assembly is installed on the frame 100, and is used to press-fit the valve pump body 102 to be pressed after the O-ring assembly is completed and the drive motor 101 to be pressed after the motor cam shaft orientation is completed.

[0053] Embodiment 2, the motor camshaft orientation assembly includes an orientation cylinder 151 and a blocking orientation rod 152, the cylinder body of the orientation cylinder 151 is installed on the measuring bracket 14, one end of the blocking orientation rod 152 is detachably installed on the end of the piston rod of the orientation cylinder 151, when the automatic assembly controller controls the piston rod of the orientation cylinder 151 to extend, the other end of the blocking orientation rod 152 is located at the active plane position of the motor camshaft of the drive motor 101 to be pressed placed on the motor positioning seat 11, and the motor camshaft orientation is completed when the drive motor 101 to be pressed rotates.

[0054] Since the drive motor 101 to be press-fitted is a purchased standard part, its assembly dimensions may not meet the press-fitting requirements. Before press-fitting, it is necessary to inspect its dimensions, especially the dimensions from the top of the motor camshaft to the bottom of the drive motor 101 to be press-fitted.

[0055] In order to realize the automatic pressing in the future, after the barcode scanner has scanned the information of the drive motor 101 to be pressed, the motor camshaft of the drive motor 101 to be pressed needs to be limited to the set position before the size is detected. This set position is to ensure that the position of the motor camshaft of the drive motor 101 to be pressed meets the subsequent connecting rod installation requirements when the robot is used for transportation and buckling. The directional cylinder 151 is used to drive the blocking directional rod 152 to extend to carry out the motor camshaft position orientation. The electric rotating platform 12 can be a rotating motor. When the electric rotating platform 12 is in motion, it can drive the drive motor 101 to be pressed to rotate. The end of the blocking directional rod 152 is inserted into the rotation plane of the motor camshaft of the drive motor 101 to be pressed. When the motor camshaft contacts the end of the blocking directional rod 152, the positioning of the motor camshaft is completed. After the positioning is completed, the size from the top of the motor camshaft to the bottom of the drive motor 101 to be pressed is detected to ensure the smooth progress of the subsequent pressing.

[0056] While the motor camshaft is being oriented and tested, the O-ring automatic assembly mechanism assembles the O-ring to the O-ring installation position of the valve pump body 102 to be press-fitted, and the automatic assembly controller controls the valve pump body transfer robot to remove the valve pump body 102 to be press-fitted with the O-ring installed, flip it over and snap it onto the drive motor 101 to be press-fitted, and finally controls the drive motor press-fitting assembly to complete the press-fitting;

[0057] The automated press-fitting of the valve pump body 102 to be press-fitted and the drive motor 101 to be press-fitted is realized, with a high pass rate, which greatly improves the assembly efficiency of the air valve pump.

[0058] Embodiment 3, the measuring assembly includes a measuring linear slide 161, a measuring seat 162, a measuring rod 163 and a displacement sensor, the track of the measuring linear slide 161 is installed on the side of the measuring bracket 14, the measuring seat 162 is installed on the slider of the measuring linear slide 161, the displacement sensor is installed in the measuring seat 162, one end of the measuring rod 163 is connected to the displacement sensor, and the other end is against the end of the motor camshaft of the drive motor 101 to be pressed, and the displacement sensor is communicated with the automatic assembly controller to exchange measurement data.

[0059] The measuring component is carried out after the motor camshaft of the drive motor 101 to be pressed is oriented. The slider action of the measuring linear slide 161 drives the measuring rod 163 to press down. The displacement sensor can measure the displacement data, and then based on the simple conversion of the basic data, the spacing data from the top to the bottom of the motor camshaft of the drive motor 101 to be pressed can be obtained.
