Abstract
The invention discloses a piston mounting device. The fixed lugs are arranged beside the two ends of through holes of a fixing plate, and the upper side of the fixing plate is fixedly connected with piston guide sleeves side by side, the diameter of the lower end hole of the inner holes of the piston guide sleeves is matched with the internal diameter of a cylinder liner. The lower ends of support legs of a bracket are fixedly connected with the outer sides of the piston guide sleeves at two ends. A pressing rod is arranged in the middle of a crossbeam of the bracket, a screw head is arranged at one end of the pressing rod and the other end is connected with a socket arranged in the middle of a transition plate. Push rods are provided below the transition plate side by side, and the push rods correspond to the piston guide sleeves. When installed, four pistons are inserted into the piston guide sleeves at the same time, screws are rotated with a pneumatic wrench, and the screws rotate to move the transition plate and the push rods downward. In this way, the four pistons are pressed into the cylinder liner evenly. Compared with the previous piston installation method, damage of different striking to the pistons and cylinder liner is avoided. In addition, the four pistons are mounted into the cylinder at the same time, and mounting efficiency is greatly improved.

Background technology
At present, automobile engine uses manual mode to be installed to by piston in cylinder cylinder holes substantially, and piston includes that piston is originally
Body and piston ring, manual installation method is: uses piston guide bush as guiding, then uses rubber hammer to be entered by piston knock by cylinder
Enter in cylinder sleeve.Such mounting means has following deficiency: 1, because dynamics is different during use rubber hammer percussion piston, be easily damaged work
Plug ring and cylinder sleeve, and then affect piston, the service life of cylinder sleeve and normal working of engine；2, low by cylinder installation effectiveness, time-consuming
Arduously.
Summary of the invention
The problem to be solved in the present invention is that four pistons are uniformly pressed into cylinder sleeve simultaneously, it is to avoid piston and cylinder sleeve are being installed
During because dynamics is different damaged, and improve the installation effectiveness of piston.
For the problems referred to above, the present invention takes techniques below scheme.Piston install equipment, including fixed plate, piston guide bush,
Support and be pressed into bar, it is characterised in that described fixed plate has been arranged side by side ring body, and the centre of ring body is provided with through hole, two end ring
The side of body is provided with auricle；It is fixedly connected with piston guide bush above ring body in described fixed plate, and piston guide bush is with fixing
The through hole of plate is coaxial；The epimere endoporus of described piston guide bush is bell mouth shape, and the hypomere endoporus of endoporus is straight hole, the internal diameter of straight hole
Match with the internal diameter of cylinder sleeve；Described support in " П " shape, outside the leg lower end of support and the piston guide bush at two ends fixing even
Connecing, be provided with and be pressed into bar in the middle of the crossbeam of support, being pressed into bar is screw-rod structure, and the one end being pressed into bar is provided with screw rod head, another
The end sleeve connection that arrange middle with rebound, has been arranged side by side pushing ram, pushing ram and piston guide bush phase below rebound
Corresponding.
Preferably, the hole wall of described epimere endoporus and the angle of axis are 4.5 ~ 7 °.
Preferably, described screw rod head is regular hexagon or square.
Preferably, described screw rod head is provided with through hole, is provided with handle in through hole.
The invention have the advantage that when installing piston, four pistons can be pressed into cylinder sleeve simultaneously uniformly, it is to avoid piston,
Cylinder sleeve is damaged in installation process, and is greatly improved installation effectiveness, saves manpower.
Accompanying drawing explanation
Fig. 1 is the perspective view of the present invention.
Fig. 2 is the piston guide bush sectional view in the present invention.
Fig. 3 is the schematic perspective view of fixed plate 1 in the present invention.
In figure: 1. fixed plate, 11. auricles, 12. through holes, 13. ring bodies, 2. piston guide bush, 3. pushing ram, 4. rebound,
41. sleeves, 5. support 51. leg, 52. crossbeams, 6. it is pressed into bar.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.Seeing Fig. 1, piston installs equipment, including solid
Determine plate 1, piston guide bush 2, support 5 and be pressed into bar 6, it is characterised in that described fixed plate 1 has been arranged side by side ring body 13, ring body 13
Centre be provided with through hole 12, the side of two ends ring body 13 is provided with auricle 11；Ring body 13 in described fixed plate 1 is the most fixing
Connect and have piston guide bush 2, and piston guide bush 2 is coaxial corresponding with the through hole 12 of fixed plate 1；The epimere endoporus of described piston guide bush 2
For bell mouth shape, the hole wall of epimere endoporus and the angle α of axis are 4.5 ~ 7 °, and hypomere endoporus is straight hole, the internal diameter of straight hole and cylinder
The internal diameter of set matches；Described support 5 in " П " shape, outside leg 51 lower end of support 5 and the piston guide bush 2 at two ends fixing even
Connecing, be provided with and be pressed into bar 6 in the middle of the crossbeam 52 of support 5, being pressed into bar 6 is screw-rod structure, and the one end being pressed into bar 6 is provided with screw rod
Head, screw rod head is regular hexagon, square or process a through hole at screw rod head, is provided with handle in through hole；The other end and rebound 4
The middle sleeve 41 arranged connects, and has been arranged side by side pushing ram 3 below rebound 4, and pushing ram 3 is corresponding with piston guide bush 2.
Embodiment: fixed plate 1 of the present invention has been arranged side by side ring body 13, the centre of ring body 13 is provided with through hole 12, two ends
Side is provided with auricle 11；Fixed plate 1 ring body 13 above is fixedly welded with piston guide bush 2, piston guide bush 2 and fixed plate side by side
Through hole 12 on 1 is coaxial corresponding, and the endoporus epimere of piston guide bush 2 is bell mouth shape, the hole wall of epimere endoporus and the angle α of axis
