The sectional type press-fitting equipment provided by the embodiment of the invention is used for dividing the press-fitting action into two steps, and is suitable for assembling relatively complex workpieces. In addition, the two-step press-fitting action is driven by the same press-fitting driving piece, so that the number of power components for providing press-fitting driving force is reduced.
In a press-fitting operation, a large press-fitting driving force is generally required, and a driving force required for a power element to achieve control is generally small; the power unit capable of improving the large driving force is generally large in size and complex in structure.

Further, a displacement sensor 012 is mounted on the press-fit movable seat 01, for detecting a displacement length of the press-fit movable seat 01 relative to the press-fit block 03.
Specifically, the displacement sensor 012 can measure the movement distance of the press-fit rod 02 driving the inner column 120 in the work 100 to be assembled with respect to the outer tube 110 in the second-step press-fitting.
The second aspect of the embodiment of the invention provides a sectional press-fitting method, which is applied to the sectional press-fitting equipment, and the sectional press-fitting method provided by the embodiment of the invention comprises the following steps:
a pre-pressing step, wherein a limiting component locks the press-fitting block 03 and the press-fitting movable seat 01, and a press-fitting driving piece drives the press-fitting movable seat 01, the press-fitting block 03 and the press-fitting rod 02 to move together;
in the in-place press-fitting step, the limiting assembly loosens the press-fitting block 03 from the press-fitting movable seat 01, and the press-fitting driving piece drives the press-fitting movable seat 01 to move together with the press-fitting rod 02, so that the press-fitting rod 02 extends outwards relative to the press-fitting block 03.
Specifically, the pre-loading step sequentially comprises the following steps:
step S110: the first cylinder 052 extends;
step S120: the press-fitting cylinder 011 extends out;
step S130: the second cylinder 062 extends;
step S140: the press-fitting cylinder 011 retreats.
The in-place press-fitting step sequentially comprises the following steps:
step S210: the first cylinder 052 is retracted;
step S220: the press-fit cylinder 011 protrudes.
The press-fitting operation of the work 100 to be assembled is completed.
The method also comprises a return step, and specifically comprises the following steps in sequence:
step S310: the second cylinder 062 retreats;
step S320: the press-fitting cylinder 011 retreats.
Specifically, the air supply line of the press-fitting cylinder 011 is connected with a pressure regulating valve, through which the air supply pressure of the press-fitting cylinder 011 is regulated to realize:
in step S120, after the press-fitting cylinder 011 drives the shoulder of the outer tube 110 in the workpiece 100 to be assembled to abut against the mounting plate, the press-fitting cylinder 011 receives upward resistance, and the piston rod of the press-fitting cylinder 011 stops moving downward;
in step S140, after the baffle of the press-fit movable seat 01 abuts against the second stopper 061, the press-fit cylinder 011 receives downward resistance, and the piston rod of the press-fit cylinder 011 and the press-fit movable seat 01 stop moving upward together.
According to the sectional press-fitting method provided by the embodiment of the invention, sectional press-fitting is realized by controlling the press-fitting cylinder 011, the first cylinder 052 and the second cylinder 062, and in the two press-fitting steps, the press-fitting cylinder 011 provides press-fitting action force.
The extension and retraction of the air cylinder are realized by controlling the on-off of the air circuit, the control is simpler, the structure of a control system is simplified, and the control stability is more reliable.
Finally, it should be noted that: in the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described by differences from other embodiments, and identical and similar parts between the embodiments are only required to be seen with each other; the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the 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 scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; embodiments and features of embodiments in this application may be combined with each other without conflict. Such modifications, substitutions and combinations do not depart from the spirit of the invention.
