[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] The utility model provides a housing clamping device for rocker arm assembly, such as Figure 1-4As shown, it includes a frame 1 and a pin loading tray 2 and an assembly mechanism 3 on the top of the frame 1. The top surface of the frame 1 is located on the right side of the assembly mechanism 3 and a clamping mechanism 4 is arranged. The assembly mechanism 3 includes a bracket A31, a servo drive unit 32, an assembly block 33 and a pressing needle 34. The servo drive unit 32 is installed on the top of the bracket A31, the bottom of the servo drive unit 32 is connected to the assembly block 33, the bottom of the assembly block 33 is connected to the pressing needle 34, the top of the clamping mechanism 4 is connected to a connecting frame 8, the other end of the connecting frame 8 is connected to the assembly block 33, and is used to follow the assembly block 33 to perform synchronous lifting and lowering movements, the bottom of the assembly mechanism 3 is arranged with a transverse module 5, the free end of the transverse module 5 is connected to a slide 6, the slide 6 is used to place the shell, and a marking machine 7 is arranged on the right side of the clamping mechanism 4.

[0020] A clamping mechanism 4 is additionally provided on one side of the assembly mechanism 3, and the assembly mechanism 3 is used to drive the clamping mechanism 4 to move downward synchronously when pressed down, and the outer shell is clamped in cooperation with the slide 6, so that the outer shell is firmly fixed on the top surface of the slide 6, and then the pins transported by the second assembly mechanism 3 are pressed down to assemble the pins into the outer shell, which effectively avoids the displacement of the outer shell caused by pressure and ensures the qualified rate of the outer shell assembly pins.

[0021] The working principle is: a large number of pins are placed in the pin loading tray 2 for orderly feeding, and the outer shell is clamped individually by a mechanical arm and placed on the slide 6. In the initial state, the slide 6 moves to the bottom of the clamping mechanism 4 through the transverse module 5. When the pin loading tray 2 is transported to the assembly mechanism 3, the servo drive unit 32 drives the assembly block 33 to move downward so that the pressure needle 34 presses the pin. At the same time, the downward moving assembly block 33 drives the clamping mechanism 4 to move relative to the outer shell through the connecting frame 8 to press down the outer shell and cooperate with the slide 6 to clamp the outer shell to prevent the outer shell from being subjected to pressure and causing position displacement. After assembly, the transverse module 5 drives the slide 6 to pass through the marking machine 7 for marking.

[0022] Specifically, the clamping mechanism 4 includes a bracket B41, a guide rail B42, a slider B43, a connecting block 44, a shock absorber 45, and a pressure cylinder 46. The middle part of the front end of the bracket B41 is fixedly connected to the guide rail B42, the slider B43 is slidably placed on the guide rail B42, one end of the connecting frame 8 is connected to the top of the slider B43, the connecting block 44 is slidably installed on one side of the slider B43, the top of the connecting block 44 is connected to the shock absorber 45, and the other end of the shock absorber 45 is connected to the connecting frame 8, and a pressure cylinder 46 is arranged at the bottom of the connecting block 44.

[0023] When the assembly block 33 drives the clamping mechanism 4 to move downward through the connecting frame 8, the slider B43 slides downward on the surface of the guide rail B42, so that the pressing cylinder 46 drives the pressing cylinder 46 at the bottom to move downward synchronously, and the pressing cylinder 46 contacts the shell first. When the assembly block 33 continues to descend, the pressing cylinder 46 is subjected to the reaction force of the shell to move upward to compress the shock absorber 45. The greater the downward movement distance of the assembly block 33, the greater the pressing force of the pressing cylinder 46 on the shell, and the assembly of the pin is completed by placing it in the assembly mechanism 3.

[0024] Furthermore, the assembly mechanism 3 also includes a slider A35 and a guide rail A36. The slider A35 is fixedly installed in the front middle part of the bracket A31, and the guide rail A36 is slidably installed at the front end of the slider A35, and the guide rails A36 are fixedly connected. The slider A35 and the guide rail A36 are used to improve the stability of the assembly block 33 when it moves downward, so that the assembly block 33 always maintains a straight line up and down movement, and prevents the reaction force of the pressure from causing the assembly block 33 to shake.

[0025] Furthermore, the connecting frame 8 is in the shape of a right-angled triangle, one of the sharp ends of the connecting frame 8 is connected to the slider B43, and one of the vertical surfaces of the connecting frame 8 is connected to the assembly block 33. The triangular connecting frame 8 is stable, thereby improving the firmness of the connection between the assembly mechanism 3 and the clamping mechanism 4.

[0026] Specifically, the pin loading tray 2 , the assembly mechanism 3 , the clamping mechanism 4 , and the marking machine 7 are arranged in sequence from left to right on the top of the frame 1 , and the slide 6 is located below the assembly mechanism 3 , the clamping mechanism 4 , and the marking machine 7 .
