The mounting plate 3 is L-shaped structure, and the bottom of the mounting plate is fixed on the mounting base 1 through bolts, so that the stability of the mounting plate 3 can be enhanced. The number of the mounting plates 3 is two and the mounting plates are symmetrically arranged on the bottom plates of the mounting seats 1 at the two sides of the bottom of the piston rod of the cylinder 2.
The number of the connecting plates 4 is two, the two connecting plates are symmetrically arranged on two sides of a piston rod of the cylinder 2, the upper end of each connecting plate 4 is hinged to the front end of the piston rod of the cylinder 2 through a first pin shaft 10, and the lower end of each connecting plate is hinged to the bottom of the front side of the mounting plate 3 on the same side of the connecting plate through a second pin shaft 11. The second pin shaft 11 penetrates through the two mounting plates 3 simultaneously.
The rear end of the pressure arm 5 is hinged to the top of the rear side of the mounting plate 3 through a third pin shaft 12 and is positioned below a piston rod of the cylinder 2, and the front end of the pressure arm extends forwards to the front of the mounting seat 3 (exceeds the edge of the front end of the mounting seat 3). The pressure arm 5 (or the third pin 12) is located between the first pin 10 and the second pin 11.
The upper end of the pressure lever 7 is fixed at the front end of the pressure arm 5, and the lower end is arranged above the part to be processed. The bottom of the pressure lever 7 is provided with a pressure head (positioned below the pressure arm 5) with the diameter larger than that of the pressure lever 7.
The number of the tension and compression plates 9 is two, the two tension and compression plates are symmetrically arranged on two sides of a piston rod of the cylinder 2, the upper end of each tension and compression plate 9 is hinged to the front end of the piston rod of the cylinder 2 through a pin shaft I10 and is located between the piston rod of the cylinder 2 and the connecting plate 4, the lower end of each tension and compression plate 9 is hinged to the rear end of the compression arm 5 and is located on the front side of the pin shaft II, and each tension and compression plate 9 is located between the connecting plate 4 and the compression arm 5.
At the beginning, the piston rod of the cylinder 2 retracts, and the lower end of the compression bar 7 is lifted. When a part is processed, the part is placed below a pressure head of a pressure rod 7 (the distance between the pressure head and the surface of the part cannot be too large and cannot be larger than the maximum downward moving distance of the pressure rod 7), an air cylinder 2 is started, a piston rod of the air cylinder 2 moves forwards, a connecting plate 4 and the upper end of a pulling and pressing plate 9 are pushed to rotate forwards, the lower end of the pulling and pressing plate 9 continuously moves downwards along with the rotation of the connecting plate 4 and the pulling and pressing plate 9, the downward movement of the pulling and pressing plate 9 presses a pressure arm 5 to rotate downwards, and the pressure rod 7 moves downwards along with the downward movement and is pressed on the part.
Example two:
the difference between this embodiment and the first embodiment is:

When the part to be processed is thin or thick, the pressing rod 7 is difficult to contact after moving downwards or the part is difficult to place below a pressure head of the pressing rod 7, the length of the pressing rod 7 on the lower side of the pressure arm 5 needs to be adjusted up and down, and the pressing rod 7 can provide sufficient pressure for the part under the action of the air cylinder 2. During adjustment, the piston rod of the air cylinder 2 retracts backwards, the pressure rod 7 is lifted, the pressure rod 7 moves up and down after the locking nut 8 is loosened, the length of the lower side of the pressure arm 5 of the pressure rod 7 reaches a proper length, the locking nut 8 is screwed down, and the pressure head is located above a part (the interval between the pressure head and the part cannot be too large, and a sufficient pressing interval is guaranteed). Then the piston rod of the cylinder 2 extends backwards, so that the press rod 7 can be pushed to press down on the part to press the part tightly.
Example three:
the difference between this embodiment and the second embodiment is:
the mounting hole 6 is an elongated hole arranged along the length direction of the pressure arm 5, and after the locking nut 8 is loosened, the pressure rod 7 can move back and forth along the mounting hole 6. Under the structure, the pressure lever 7 can be adjusted forwards and backwards to adapt to parts with different shapes and specifications.
When the part is arranged below the pressure head, if the pressure head is too close to a processing point or the pressure head is too close to the edge position of the part, and other situations occur, the position of the pressure head needs to be adjusted, during adjustment, the locking nut 8 is slightly loosened, the pressure rod 7 is in a movable state, then the locking nut 8 is screwed again after the pressure rod 7 is slid back and forth along the mounting hole 6 to a proper position, and the operation of pressing the part can be carried out.
It is to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
