The purpose of this utility model can also further realize by following technical measures.
Aforesaid piston pin vertical lifting frock, wherein said cone-shaped ejecting block rotation-preventing mechanism comprises several anti-rotating pins and several anti-rotation grooves corresponding with anti-rotating pin respectively, described several anti-rotation groove is distributed on the elastic expansion sleeve bottom, several anti-rotating pin one ends are horizontal in corresponding anti-rotation groove respectively, and several anti-rotating pin other ends are vertically fixed on respectively in the cone-shaped ejecting block upper end.
Aforesaid piston pin vertical lifting frock, wherein said several anti-rotation grooves and several axial elastic trough are crisscross arranged.
Aforesaid piston pin vertical lifting frock, wherein said elastic expansion sleeve top is polyhedral structure.
The light and handy compactness of the utility model structure, low cost of manufacture, safe and convenient to use, only need a people to use two common wrench fixedly elastic expansion sleeve, rotation adjusting bolt simultaneously, tightly push down gudgeon pin bore after just under the combined action of adjusting bolt and cone-shaped ejecting block, making the lower swelling section of elastic expansion sleeve radially increase, utilize increase or the disappearance of the static friction force between elastic expansion sleeve and gudgeon pin bore, the lifting that completes fast piston pin clamps or loosens unloading, thereby can handling or unload piston pin.The utility model not only can reduce by a labour power while using, reduce the processing supplementary costs of piston pin, also can make work efficiency improve more than 3 times.And operating process is laborsaving, safe, reliable, avoid weighing wounded the accident of bearer's finger, reached the double effects of carrying out production strictly in line with rules and regulations with cost efficiency.
Advantage and disadvantage of the present utility model, will carry out the figure explanation by the non-limitative illustration of following preferred embodiment, and these embodiment, only provide as an example with reference to accompanying drawing.
The accompanying drawing explanation
Fig. 1 is the cutaway view that adopts the utility model handling piston pin;
Fig. 2 is the A-A cutaway view Amplified image of Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As depicted in figs. 1 and 2, the utility model comprises lifting eye bolt 1, adjusting bolt 2, elastic expansion sleeve 3, cone-shaped ejecting block 4 and cone-shaped ejecting block rotation-preventing mechanism 5, adjusting bolt 2 is through elastic expansion sleeve 3, its top is provided with is convenient to the six-sided head 21 that spanner blocks, while rotating with assurance adjusting bolt 2, elastic expansion sleeve 3 can not rotate thereupon; Six-sided head 21 lower ends are provided with the positioning table 22 radially extended, and positioning table 22 is resisted against on the upper surface of elastic expansion sleeve 3, while rotating with assurance adjusting bolt 2, can not be moved.Lifting eye bolt 1 lower end is threaded connection and is fixed on adjusting bolt 2 upper ends, and adjusting bolt 2 lower ends are threaded with cone-shaped ejecting block 4 upper ends.
Elastic expansion sleeve 3 tops are polyhedral structure, and the present embodiment is the six-sided head 31 that available spanner blocks, and also can be the tetragonal body structure.The axial elastic trough 32 that open 3 upper end closed lower ends of elastic expansion sleeve 3 bottom radial equipartition, elastic expansion sleeve 3 upper, upper guide section 33 and the lower swelling section 34 of side face and gudgeon pin bore 61 free-running fits radially extended respectively in lower end, 33 pairs of upper guide sections are put into the elastic expansion sleeve 3 of gudgeon pin bore 61 and are played a supporting role, the internal tapered hole 341 of lower swelling section 34 lower ends and the male-tapered face 41 at cone-shaped ejecting block 4 middle parts match, lower swelling section 34 is subject to distending after the extruding of cone-shaped ejecting block 4, utilize the increase effect of the positive pressure of the 34 pairs of gudgeon pin bores 61 of lower swelling section after distending, make lower swelling section 34 and the static friction force between gudgeon pin bore 61 of elastic expansion sleeve 3 increase, when this static friction force during much larger than the gravity of piston pin 6, when moving up and down, just can move with piston pin 6 elastic expansion sleeve 3, be that available loop wheel machine is by lifting rope and lifting eye bolt 1 handling piston pin 6.
