It should be understood that the press-fitting apparatus set forth in the present invention should not be limited by the exemplary embodiments set forth herein. Rather, these examples are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
As shown in fig. 1, the present embodiment provides a press-fitting apparatus for pressing a valve core shaft 5 into a valve core 2, including: the valve core shaft feeding assembly 51 can feed the valve core shafts 5 one by one, and the feeding end of the valve core shaft feeding assembly 51 is communicated with the vibration feeding unit 120; the attitude adjusting assembly 52 is used for adjusting the attitude of the valve core shaft 5 to be capable of being pressed into the valve core 2, and the attitude adjusting assembly 52 is connected with the valve core shaft feeding assembly 51; the press-fitting assembly 53 can perform lifting movement in the vertical direction so as to press-fit the valve core shaft 5 adjusted by the posture adjustment assembly 52 into the valve core 2 from above the valve core 2; and a jacking assembly 55 arranged at the bottom of the press-fitting assembly 53 and used for providing a vertically upward supporting force for the press-fitting assembly 53 in the press-fitting process.
The press fitting device provided by the embodiment can press the valve core shaft 5 into the valve core 2 in a correct posture through the arrangement of the posture adjusting assembly 52, so that the quality of a product is ensured, and the press fitting efficiency is high. Through the arrangement of the jacking assembly 55, in the process of pressing down the press-fitting assembly 53, enough vertical upward supporting force can be provided for the press-fitting assembly 53, the valve core shaft can be pressed in place at one time, the press-fitting quality is improved, and meanwhile, the press-fitting device is prevented from being damaged.
As shown in fig. 2, the poppet shaft feed assembly 51 communicates with the attitude adjustment assembly 52 to feed the poppet shaft 5 to the attitude adjustment assembly 52. In the feeding process, in order to ensure that only one valve core shaft 5 enters the attitude adjusting assembly 52 at a time, a stopping mechanism 54 capable of feeding the valve core shafts 5 to the attitude adjusting assembly 52 one by one is arranged at one end of the valve core shaft feeding assembly 51 connected with the attitude adjusting assembly 52, and the stopping mechanism 54 is positioned below the valve core shaft 5 to enter the attitude adjusting assembly 52.
The operation of the park mechanism 54 is generally as follows, when the horizontal state of the valve shaft 5 from the valve shaft feeding assembly 51 has not entered the attitude adjustment assembly 52, that is, the valve shaft 5 about to enter the attitude adjustment assembly 52 is completely above the park mechanism 54, and the park mechanism 54 is in a compressed state; in this state, the axis of the spool shaft 5 corresponds to the attitude adjustment assembly 52 to be entered, and the spool shaft 5 can continue to be fed into the attitude adjustment assembly 52. After the valve core shaft 5 enters the attitude adjusting assembly 52 and starts attitude adjustment along with the attitude adjusting assembly 52, the stop mechanism 54 can be reset and lifted, the axis of the valve core shaft 5 which is positioned above the stop mechanism 54 and does not enter the attitude adjusting assembly 52 at all is higher than the attitude adjusting assembly 52 which is about to enter, and the valve core shaft 5 is in a state that the valve core shaft cannot continue to feed at the moment, so that the valve core shaft is temporarily stopped.
As shown in fig. 1, 2 and 5, the attitude adjustment assembly 52 includes: a rotation correcting unit 521 for correcting the spool shaft 5 in the horizontal state to the vertical state; and a flat side positioning unit 522 capable of rotating the spool 5 around the axis of the spool 5 to a press-fitted state.
After the spool shaft 5 leaves the stop mechanism 54, the spool shaft enters the rotation and correction unit 521 of the attitude adjustment assembly 52, as shown in fig. 2 and 4. When the rotary correcting unit 521 is in its initial position, that is, the spool shaft 5 capable of receiving horizontal feeding, the rotary correcting unit 521 can press down the stopping mechanism 54 to make the stopping mechanism 54 in a compressed state, so that feeding of the spool shaft 5 is not blocked; when the rotation and adjustment unit 521 drives the spool shaft 5 to rotate so that the spool shaft 5 rotates from the horizontal state to the vertical state, the rotation and adjustment unit 521 leaves the stopping mechanism 52, and at this time, the stopping mechanism is lifted and reset, so that the feeding of the spool shaft 5 is temporarily stopped.
Specifically, the stop mechanism 54, as shown in fig. 3, includes: the elastic member 541 for restoring and lifting the stopping mechanism 54 may be, in this embodiment, a member such as a spring that can be pressed down under pressure and can be restored after the pressure is released, which is not limited by the present invention; an actuating member 542 which can be pressed down and actuated by the rotary setting unit 521 in a feeding receiving state to compress an elastic member, wherein the actuating member 542 is arranged above the elastic member 541; a follower 543 capable of moving up and down along with the elastic component 541 in a vertical direction, wherein the follower 543 is disposed above the elastic component 541.
In the feeding direction of the spool shaft 5, the follower 543 and the actuating member 542 are sequentially disposed, and the actuating member 542 is disposed adjacent to the attitude adjustment assembly 52.
The arrangement of the follower 543 and the actuator 542 in cooperation with the elastic member 541 ensures that only one valve core shaft 5 can be fed at a time. The actuator 542 is close to the rotary swing unit 521, and the follower 543 moves up and down along with the actuator 542, so that the up and down movement of the follower 543 has a certain time lag with the actuator 542; when the rotating and straightening unit 521 presses the actuator 542 downwards, the valve core shaft 5 can rapidly enter the rotating and straightening unit 521; when the rotating and centering unit 521 rotates away from the stop mechanism 54, the actuating member 542 will be lifted and reset before the follower 543, so that the valve core shaft 5 is well in the feeding direction, and the feeding front end is blocked to stop feeding, thereby achieving the stop action efficiently.
The press mounting device provided by the embodiment adopts a simple mechanical structure to realize one-by-one feeding of the valve core shaft 5, avoids adopting excessive automatic facilities such as photoelectric sensors and the like, is easy for daily maintenance, and reduces the cost of the press mounting device.

The rotary righting unit 521 can quickly right the valve core shaft 5 in the horizontal state to the vertical state, and prepare for the next angular adjustment. The rotating and aligning unit 521 is further provided with an arc-shaped plate 5213 for limiting the valve core shaft 5 in the rotating process, so that the valve core shaft 5 can be prevented from being thrown out due to centrifugal force when rotating along with the convex piece 5211.

That is, when the receiving device can receive the laser from the emitting device, that is, the angle of the valve core shaft 5 is the correct angle, the valve core 2 can be vertically press-fitted.
The flat side positioning unit 522 provided by this embodiment also positions the angle required for press-fitting the valve plug shaft 5 by a simple mechanical structure in cooperation with a laser sensor, so that the yield of the assembled valve plug is greatly improved.
Further, the press-fitting device provided by the embodiment is further provided with a station jig 110 for placing the valve element 2 to be press-fitted. The station jig 110 is located below the press-fitting assembly, and the station jig 110 is provided with a mistake-proofing structure, which enables the valve element 2 to be fixedly placed on the station jig 110.

the abutting piece 112 is arranged on one side of the station jig 110, and the abutting piece 112 faces the side surface of the valve core 2 placed on the station jig 110 and is provided with an arc-shaped inosculating surface 114 attached to the outer peripheral surface of the valve core. The cylindrical part 113 is arranged in the middle of the station jig 110, and when the valve core 2 is placed in the station jig 110, the cylindrical part 113 is fitted with the hollow structure inside the valve core 2.
When the valve core 2 is seen from a top view, one side of the valve core 2 is provided with a flat structure, so that the valve core 2 can be ensured not to rotate in the circumferential direction by limiting the flat structure. And the bottom of the valve core 2 is hollowed-out circular, and the cylindrical protruding part 113 arranged on the station jig 110 is just matched with the hollowed-out circular part, so that the valve core 2 is ensured not to move in the horizontal direction.
Further, the valve core press-fitting device further comprises, as shown in fig. 1, a valve core shaft transplanting assembly 154 for delivering the valve core shaft 5 in a vertical state from the rotary righting unit 521 to the flat side positioning unit 522 and delivering the valve core shaft 5 in a press-fitting state from the flat side positioning unit 522 to the press-fitting assembly 53;
the spool transplanting assembly 154 includes: the press-fitting component 53 includes a clamping jaw capable of clamping the valve core shaft 5 for delivery, and a transfer member capable of receiving the valve core shaft 5 from the flat side positioning unit 522 and completing posture adjustment, wherein the transfer member drives the valve core shaft 5 to move in the horizontal direction, so that the valve core shaft 5 is delivered to the press-fitting component 53 without changing the posture of the valve core shaft 5. The press-fitting assembly 53 grips the valve core shaft 5 and presses it down into the valve core 2 below the press-fitting assembly 53.
Due to the arrangement of the transfer piece, the valve core shaft 5 with the adjusted posture can be conveyed to the lower part of the press fitting assembly 53 without changing the posture, the press fitting assembly 53 can complete clamping and press fitting of the valve core shaft 5 only by reciprocating in the vertical direction, the structure of the press fitting assembly 53 is simplified, and the whole maintenance of the press fitting device is convenient.
Preferably, a pressure sensor may be further provided on the pressure head of the press-fitting assembly 53 to detect the pressure of the valve element obtained after the valve element shaft 5 is press-fitted, and feed back the detected value to a controller (not shown), and the controller determines whether the detected value is within a set value range, and determines that the valve element is defective if the detected value is not within the set value range.
In order to provide a vertical upward supporting force for the press-fitting assembly 53 in the press-fitting process, so that the valve core shaft 5 can be press-fitted in place at one time, and the product quality is improved, a jacking assembly 55 may be further provided below the press-fitting assembly 53, as shown in fig. 7.
The jacking assembly 55 preferably comprises a first jacking member 551, a second jacking member 552 abutting against the second jacking member 551 to provide an upward supporting force to the first jacking member 551, and a cylinder 553 providing a horizontal supporting force to the second jacking member 552. Of course, to facilitate the positioning of the jacking assembly 55, a base 554 may also be provided on the top of the jacking assembly 55. As shown in fig. 7, the abutting surfaces of the first lifting member 551 and the second lifting member 552 are inclined surfaces, the first lifting member 551 can only displace in the vertical direction, the second lifting member can only displace in the horizontal direction, and by this arrangement, a friction force in the horizontal direction exists between the first lifting member 551 and the second lifting member 552, and the air cylinder 553 only needs to provide a force corresponding to the friction force in the horizontal direction, i.e., an upward supporting force can be provided for press-fitting the press-fitting component 53. The horizontal friction force is much smaller than that of the cylinder located directly at the bottom of the press-fitting assembly 53, which directly provides a vertically upward supporting force, so that a powerful cylinder is not required in this embodiment.
The working principle is as follows:
