Above the belt 7, the dust cover 23 to match with rack 1 is additionally provided with, is provided on the top of dust cover 23
Handle 24.
The course of work of the piston rod automatic press mounting mechanism of the utility model embodiment is as follows：It needs bearing shell being fitted in
When on connecting rod, by control system feeding stepping cylinder 2 is controlled to work first, 2 drive link 4 of feeding stepping cylinder is toward physical pendulum
Dynamic, since the top of connecting rod 4 is connected by unilateral bearing 6 with rack 1, during connecting rod 4 is swung, connecting rod 4 is to the left
During swing, unilateral bearing 6 rotates together together with drive roll, and when connecting rod 4 is swung to the right, unilateral bearing 6 dallies, and passes through this side
Formula does stepwise operation using drive roll drive belt 7（One unit distance of traveling each time）, progressively by workpiece bearing shell from skin
The other end is transported to 7 one end；
When bearing shell moves to the feeding station of 7 end of belt, lifting cylinder 9 drives clip claw mechanism downlink, and passes through folder
Pawl cylinder 10 controls clamping jaw action, bearing shell is captured, then rotary cylinder 8 drives mechanism all in small rack to rotate together
180 °, bearing shell turns to the top of press fitting slide unit 12 at this time；Then lifting cylinder 9 drives clip claw mechanism downlink, coordinates with clamping jaw
Bearing shell is placed on workpiece positioning table 27 by the action of cylinder 10, and the position of bearing shell and briquetting 19 matches at this time；
Then control system can control press fitting cylinder 26 to work, and drive press fitting slide unit 12 is whole to be moved along slideway 11, the
Briquetting 19 on two slide units 14 can also move therewith, and bearing shell direction is promoted to be pre-positioned the company being clamped on workpiece positioning table 27
The direction movement of bar, until bearing shell is smoothly fitted on connecting rod；
In order to which bearing shell can be fitted on connecting rod, it is necessary first to bearing shell be allowed to generate certain flexible deformation, and entered
Automatic spreading behind junction on connecting rod, to achieve these goals, by two guide blocks 16 it is opposite be arranged to cambered surface 18 on one side,
Due to the presence of two cambered surfaces 18, when allowing the bearing shell to move by press fitting passage 17 form a kind of structure of closing in, such axis
Watt closer to connecting rod, deflection is bigger, ensures that it can be fitted in link position；Briquetting 19 is also required to by above-mentioned simultaneously
It is pressed passage 17, therefore the overall width of briquetting 19 is also required to carry out the variation of adaptability, is being pressed when briquetting 19 is whole
In passage 17 during movement, the swing component 21 of first 20 both sides of arc can be swung under the action of cambered surface 18, conjugated spring 22 at this time and pressed
Bearing shell can smoothly be press-fit into place by contracting, briquetting 19；When briquetting 19 recycles, under the action of two conjugate spring 22, pendulum
Moving part 21 can be returned to original state again, and press fitting next time is waited to operate；This structure can ensure during the motion, to press
Two swing components 21 in block 19 can be contacted with cambered surface 18 always, ensure the effect being oriented to.
As above-mentioned action is repeated, you can realize the automation mechanized operation being fitted in bearing shell in connecting rod.
