The embodiment provides a steering cylinder shaft pin dismounting tool, which comprises a hanging frame 4, a plurality of cushion blocks 5, a telescopic device and a cylinder body 6.
The hanger 4 defines a first compression surface L, a second compression surface M, and a relief space between the first compression surface L and the second compression surface M, as shown in fig. 2.
The cylinder 6 is a hollow structure with an open end and a closed end, as shown in fig. 3.
When dismantling pivot 3 between piston rod 1 and the otic placode 2 in the steering cylinder, if the one end of pivot 3 does not have sufficient dismouting space, the accessible removes stores pylon 4, make pivot 3 be located the space of stepping down, and locate the one end of pivot 3 with cushion 5, locate the other end of pivot 3 with the telescoping device, barrel 6 is then located between the other end and the telescoping device of pivot 3, outwards stretch out the pars contractilis of telescoping device, make first clamping face L and cushion 5 counterbalance, second clamping face M and telescoping device counterbalance, the blind end and the telescoping device counterbalance of barrel 6, and the open end of barrel 6 supports and leans on otic placode 2 adjacent with the other end of pivot 3. The telescopic part is extended continuously, the pressing shaft pin 3 can move towards the cylinder 6, and the cylinder 6 provides a containing space for the movement of the shaft pin 3. After the cushion block 5 is sunk into the lug plate 2 adjacent to one end of the shaft pin 3 and the first pressing surface L is abutted against the lug plate 2, the telescopic part is retracted for a certain stroke, another cushion block 5 is stuffed between the cushion block 5 and the first pressing surface L again, then the telescopic part is continuously extended out, the shaft pin 3 can be pressed again to move towards the barrel 6, and the operation is repeated, so that the shaft pin 3 can be completely taken out.
The principle of the dismounting tool of the embodiment is easy to understand, the structure is simple, the manufacturing is easy, the operation is convenient, and the dismounting efficiency is high. In addition, the dismounting tool can be used for dismounting the vertically extending shaft pin 3 and can also be used for dismounting the shaft pin 3 extending along other directions, the practicability is high, the dismounting process cannot damage the shaft pin 3 and other structures, and the maintenance cost is saved.
As shown in fig. 3, when the steering cylinder is placed horizontally and the axle pin 3 extends vertically, if the space above the axle pin 3 is limited, the hanger 4 can be hung on the top end of the axle pin 3, the telescopic device can be placed on the second pressing surface M, and the cylinder 6 is placed on the telescopic part of the telescopic device with the opening facing upwards. Since the top end of the shaft pin 3 protrudes from the lug plate 2 above the piston rod 1 in the initial state, the first pressing surface L can be directly abutted against the top end of the shaft pin 3 when the shaft pin 3 is pressed downwards for the first time.
After the telescopic part of the telescopic device extends upwards for a first stroke, the open end of the cylinder 6 abuts against the lug plate 2 below the piston rod 1. When the telescopic part continues to extend upwards, the pin shaft is extruded to move downwards, and after the telescopic part continues to extend to the second stroke, the top end of the pin shaft 3 is flush with the lug plate 2 above the piston rod 1. In order to continuously press the shaft pin 3 to move downwards, the telescopic part can be firstly retracted downwards, a cushion block 5 is filled between the first pressing surface L and the top end of the shaft pin 3, then the telescopic part extends upwards again, when the shaft pin 3 is pressed to move downwards by the first pressing surface L and the first pressing surface L is abutted against the lug plate 2 above the piston rod 1, the steps are subsequently continued until the shaft pin 3 is detached.
In this embodiment, the cushion block 5 is a circular cushion block 5, the cylinder 6 is a circular cylinder 6, and the diameter of the cushion block 5 is smaller than the inner diameter of the cylinder 6 so as to ensure the adaption with the correspondingly detached shaft pin 3.
In some embodiments, the cushion block 5 may also be a circular truncated cone structure, a rectangular parallelepiped structure, or the like, the size of the cushion block 5 only needs to satisfy that it can enter the pin hole of the ear plate 2, the cylinder 6 may also be a rectangular cylinder 6, and the size of the cylinder 6 only needs to satisfy that the pin 3 can enter the cylinder 6.
As shown in fig. 3, in order to realize smooth jacking and facilitate real-time control of the operator when the telescopic part extends upwards, in this embodiment, the telescopic device comprises a jack 7 and a manual hydraulic pump 8 for controlling the jack 7.
As shown in fig. 2, in the present embodiment, the hanging rack 4 includes a first pressing plate 41, a second pressing plate 42, and a C-shaped connecting member 43 connected between the first pressing plate 41 and the second pressing plate 42. The first pressing plate 41 defines a first pressing surface L, the second pressing plate 42 defines a second pressing surface M, and the first pressing plate 41, the second pressing plate 42 and the C-shaped connecting piece 43 can be fixed by welding.
In order to improve the structural strength of the hanger 4, in the present embodiment, the hanger 4 has two C-shaped connecting members 43, and the two C-shaped connecting members 43 are disposed at an angle a therebetween, as shown in fig. 2. When placing the hanger 4 on the ground or other flat surface, the two C-shaped connectors 43, set at angle a, help to improve the stability of the placement of the hanger 4, facilitating storage or temporary storage.
Since the cushion block 5 needs to be filled many times during the downward movement of the pressing shaft pin 3, in order to reduce the time for aligning the cushion block 5, in some embodiments, a first positioning groove and a first positioning boss may be formed at opposite ends of the cushion block 5, respectively. When cushion 5 stacks, cartridge cooperation forms first location structure between first locating groove, the first locating boss, and not only the firm stack that does benefit to between the adjacent cushion 5, still does benefit to and saves the alignment time.
The appearance structures and the number of the first positioning groove and the first positioning boss can be specifically set according to actual needs, and in some embodiments, the first positioning groove and the first positioning boss can form matched guide inclined planes so as to realize quick alignment and insertion.
In order to realize the positioning fit between the cushion block 5 and the first compression surface L, in some embodiments, a first positioning groove may be further formed on the first compression surface L, and the first compression surface L and the cushion block 5 abutted against the first compression surface L form a positioning fit through the first positioning groove and the first positioning boss.
To achieve a locating fit between the telescoping device and the barrel 6, in some embodiments, a second locating feature may also be formed between the telescoping portion of the telescoping device and the closed end of the barrel 6, which may include a second locating groove formed on the telescoping portion and a second locating boss formed on the closed end.
The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
