[0027] Please refer to Figures 1 to 7 To achieve the above purpose, the utility model provides the following technical solutions:

[0028] An automatic press-fitting mechanism for an exhaust valve of an air valve pump comprises a base plate 1 and a mounting plate 2 arranged above the base plate 1, wherein the base plate 1 is movably connected to the mounting plate 2; an avoidance groove 3 is provided at the front end of the mounting plate 2, wherein exhaust valve press-fitting assemblies 4 are respectively provided on both sides of the avoidance groove 3, and two adjacent groups of exhaust valve press-fitting assemblies 4 have the same structure and are symmetrically arranged; a rodless cylinder 5 is provided on one side of the base plate 1, wherein the rodless cylinder 5 is arranged below the mounting plate 2; a floating connecting pin 6 is provided on the slider of the rodless cylinder 5, wherein a limiting groove 7 adapted to the floating connecting pin 6 is provided on the side of the mounting plate 2 close to the rodless cylinder 5, and the top end of the floating connecting pin 6 extends upward and is arranged in the limiting groove 7.

[0029] Before the mechanism is started, the mounting plate 2 is connected to the slider of the rodless cylinder 5 through the floating connecting pin 6 and is in the initial position. At this time, the exhaust valve pressing assembly 4 is also in standby state; when an air valve pump is placed in the specified position, the rodless cylinder 5 slides by driving the slider, so that the slider drives the floating connecting pin 6 to move in the limit groove 7, and then drives the mounting plate 2 to move precisely horizontally along the base plate 1 through the floating connecting pin 6, thereby ensuring that the mounting plate 2 and the exhaust valve pressing assembly 4 thereon can be accurately aligned with the air valve pump to be pressed and start working, eliminating the problem of improper assembly caused by the operator's skill level and fatigue in manual assembly, and the automated pressing process reduces dependence on manual labor, reduces labor costs, and greatly improves the assembly efficiency and quality of the exhaust valve of the air valve pump.

[0030] Please refer to Figures 1 to 3 As an embodiment of the utility model, two rectangular support blocks 8 are arranged between the base plate 1 and the mounting plate 2, wherein the lower end of the rectangular support block 8 is fixedly connected to the base plate 1; a linear guide rail 9 is fixedly installed on the upper end of the rectangular support block 8 along its length direction, wherein a guide rail slider 10 is slidably connected to the linear guide rail 9, and the top of the guide rail slider 10 is fixedly connected to the mounting plate 2; two groups of buffers 11 are symmetrically installed on the base plate 1, wherein the buffer 11 is fixedly connected to the base plate 1 through a support seat 12; a proximity switch 13 is arranged on the support seat 12, wherein the proximity switch 13 is arranged below the buffer 11; a buffer limit block 14 is fixedly connected to the lower end of the mounting plate 2, wherein the buffer limit block 14 is arranged between two adjacent groups of buffers 11; a limit screw 15 is provided on the buffer limit block 14, wherein the limit screw 15 and the proximity switch 13 arranged on the support seat 12 are at the same horizontal height.

[0031] In the above-described scheme, the rectangular support block 8 is fixed on the base plate 1, and the rectangular support block 8 provides stable support for the mounting plate 2, wherein the linear guide rail 9 installed on the upper end of the rectangular support block 8 ensures that the mounting plate 2 can perform smooth linear motion along a determined path, and the sliding connection between the guide rail slider 10 and the linear guide rail 9 enables the mounting plate 2 to perform precise horizontal movement along the linear guide rail 9 under the drive of the rodless cylinder 5; the buffer 11 is fixed to the base plate 1 through the support seat 12, wherein the buffer 11 is symmetrically distributed on both sides of the moving path of the mounting plate 2, and the function of the buffer 11 is to provide necessary buffering during the movement of the mounting plate 2 to prevent the mounting plate 2 from generating excessive impact force when it moves quickly or stops; when the mounting plate 2 moves to a position close to the limit of its stroke, the buffer limit block 14 will first contact the buffer 11, thereby slowing down the mounting plate 2 The moving speed is to avoid direct collision with the hard limit; the proximity switch 13 is installed on the support seat 12 and is arranged below the buffer 11. The proximity switch 13 and the limit screw 15 on the buffer limit block 14 are at the same horizontal height. When the mounting plate 2 moves to a position close to the limit of its stroke, the limit screw 15 will trigger the proximity switch 13. Once the proximity switch 13 is triggered, a signal will be sent to the control system, indicating that the mounting plate 2 has reached the predetermined position. The control system can stop the drive of the rodless cylinder 5 according to this signal, thereby ensuring that the mounting plate 2 does not exceed its safe moving range; after each pressing operation is completed, the mounting plate 2 will return to its initial position under the drive of the rodless cylinder 5. In this process, the buffer 11 and the proximity switch 13 play a role of protection and control, ensuring that the mounting plate 2 can accurately and safely return to its initial position.

During the pressing process, the servo electric cylinder 401 can be precisely controlled according to the preset program and parameters to ensure that the force, speed and position of the pressing meet the expected requirements. The reflective photoelectric sensor 20 and other sensors will continue to monitor various parameters of the pressing.
