The fixing frame 23 is also provided with a pushing block mechanism for abutting and cooperating with the outer wall of the rearview mirror mounting shell 1. The limit block 8 cooperates with the pushing block mechanism to limit the movement of the rearview mirror mounting shell 1 between the X axis and the Y axis during the processing.

[0026] The clamping mechanism 3 includes a first oil cylinder 31, a driving rod 32, a clamping rod 33 and a connecting rod 34. The driving rod 32 is installed at the output end of the first oil cylinder 31, and the clamping rod 33 is hinged to the end of the driving rod 32. The first oil cylinder 31 is provided with a connecting seat 311. One end of the connecting rod 34 is hinged to the connecting seat 311, and the other end of the connecting rod 34 is hinged to the middle of the clamping rod 33. The driving rod 32 is driven by the first oil cylinder 31 to reciprocate between the first position and the second position along the Z-axis direction.

[0027] When the driving rod 32 is located at the first position, the clamping rod 33 is set at an angle to the horizontal plane. At this time, the clamping rod 33 is not in contact with the process block 11, so that the rearview mirror mounting shell 1 can be assembled and disassembled.

[0028] When the driving rod 32 is located at the second position, the clamping rod 33 is in a horizontal state. At this time, the clamping rod 33 is in contact with the process block 11 , thereby achieving the function of clamping the process block 11 .

The push rod 42 is reciprocated between the third position and the fourth position along the Z-axis direction by the second oil cylinder 41.

[0030] When the ejector pin 42 is located at the third position, the clamping rod 33 is not in contact with the process block 11 .

[0031] When the ejector pin 42 is located at the fourth position, the clamping rod 33 is in contact with the process block 11 , thereby cooperating with the clamping rod 33 to clamp the process block 11 .

[0032] The limit block 8 has a raised portion 81 , the lower end surface of the raised portion 81 abuts against the upper end surface of the rearview mirror mounting shell 1 , and the side end surface of the raised portion 81 abuts against the flange 12 .

[0033] The pushing block mechanism described in this application is divided into two groups. When processing the rearview mirror mounting shell 1, one of the two groups of pushing block mechanisms is located on the left side of the rearview mirror mounting shell 1, and the other is located on the front side of the rearview mirror mounting shell 1.

[0034] The pushing block mechanism includes a mounting base 51, a third oil cylinder 52 and a pushing block 53. The mounting base 51 is fixedly mounted on the fixing frame 23. The third oil cylinder 52 is mounted on the upper end of the mounting base 51. The pushing block 53 is driven and mounted on the output end of the third oil cylinder 52. The third oil cylinder 52 drives the pushing block 53 to reciprocate between the fifth position and the sixth position in the horizontal direction.

[0035] When the pushing block 53 is located at the fifth position, there is no contact between the pushing block 53 and the process block 11 .

[0036] When the push block 53 is located at the sixth position, the push block 53 is in contact with the process block 11 , and the push block 53 cooperates with the limiting block 8 to limit the movement of the rearview mirror mounting housing 1 in the horizontal direction.

[0037] It should be noted that when processing the rearview mirror mounting shell 1, the first fixing seat 24 and the second fixing seat 25 are located on the right side of the rearview mirror mounting shell 1, the third fixing seat 26 is located on the rear side of the rearview mirror mounting shell 1, and the fourth fixing seat 27 is located on the left side of the rearview mirror mounting shell 1.

[0038] Further optimized, a turning clamp mechanism 6 and a second push rod mechanism 7 are installed on the first fixed seat 24, and the turning clamp mechanism 6 and the second push rod mechanism 7 cooperate to clamp the connecting plate 13, and the turning clamp mechanism 6 includes a rotating cylinder 61 and a pressure block 62, and the pressure block 62 is rotatably installed at the output end of the rotating cylinder 61, and the second push rod mechanism 7 includes a fourth oil cylinder 71 and an abutment rod 72, and the abutment rod 72 is driven and installed at the output end of the fourth oil cylinder 71, and the fourth oil cylinder 71 is fixedly installed on the fixed frame 23, and the pressure block 62 swings back and forth between the seventh position and the eighth position around the Z-axis direction, and the abutment rod 72 moves back and forth between the ninth position and the tenth position along the Z-axis direction.

[0039] When the pressing block 62 is located at the seventh position and the abutting rod 72 is located at the ninth position, the pressing block 62 and the abutting rod 72 are not in contact with the connecting plate 13 .

[0040] When the pressure block 62 is in the eighth position and the abutment rod 72 is in the tenth position, the pressure block 62 and the abutment rod 72 are both in contact with the connecting plate 13, and the pressure block 62 abuts against the upper end of the connecting plate 13, and the abutment rod 72 abuts against the lower end of the connecting plate 13, thereby achieving the function of clamping and fixing the connecting plate 13.

[0041] It should be noted that the rotating cylinder 61 will move axially while rotating, so that it can ensure that the pressing block 62 can achieve abutment and fit with the connecting plate 13 after rotation.

[0042] In the initial state, the driving rod 32 is at the first position, the ejector rod 42 is at the third position, the push block 53 is at the fifth position, the pressing block 62 is at the seventh position, and the contact rod 72 is at the ninth position.

At this time, by starting the first oil cylinder 31, the second oil cylinder 41, the third oil cylinder 52, the fourth oil cylinder 71 and the rotating cylinder 61, the start of the first oil cylinder 31 drives the driving rod 32 to move from the first position to the second position, thereby making the clamping rod 33 abut against the upper end of the process block 11, and the start of the second oil cylinder 41 drives the push rod 42 to move from the third position to the fourth position, thereby making the push rod 42 abut against the lower end of the process block 11, and the clamping effect of the process block 11 is achieved through the cooperation of the clamping rod 33 and the push rod 42. The third oil cylinder 52 is started The push block 53 is driven to move from the fifth position to the sixth position, so that the push block 53 is abutted and matched with the side end of the rearview mirror mounting shell 1. The push block 53 cooperates with the limit block 8 to limit the movement of the rearview mirror mounting shell 1 in the horizontal direction. The rotary cylinder 61 drives the pressure block 62 to move from the seventh position to the eighth position, so that the pressure block 62 is abutted and matched with the upper end surface of the connecting plate 13. The fourth oil cylinder 71 is started to drive the pressure block 62 to move from the ninth position to the tenth position, so that the abutment rod 72 is abutted and matched with the lower end surface of the connecting plate 13. Through the cooperation between the pressure block 62 and the abutment rod 72, the function of fixing the connecting plate 13 is achieved. Through the above-mentioned cooperation, the function of fixing and clamping the rearview mirror mounting shell 1 is achieved.
