Referring to fig. 1-4, fig. 1-3 show the structure of the press-fitting mechanism in the embodiment of the present invention, and fig. 4 shows the structure of the press-fitting member in the embodiment of the present invention; the present embodiment provides a press-fitting mechanism 200, and the press-fitting mechanism 200 includes a frame 210, a positioning assembly 220, a press-fitting unit 230, and a power unit 240.
The positioning assembly 220 is connected with the frame 210, and the positioning assembly 220 is used for installing the pipe cover 10 and the collecting main 20;
the press-fitting unit 230 includes a first press-fitting portion 231 and a second press-fitting portion 232, wherein the first press-fitting portion 231 and the second press-fitting portion 232 are movably connected;
the power part 240 is connected to the frame 210, the first press-fitting part 231 is connected to the movable end 241 of the power part 240, and the power part 240 is used for driving the press-fitting part 230 to move toward the positioning assembly 220, so that the second press-fitting part 232 is in surface contact with the header 20 and presses the tube cover 10 onto the end of the header 20.
The press-fitting mechanism 200 operates on the following principle:
referring to fig. 1-4, the press-fitting mechanism 200 includes a frame 210, a positioning assembly 220, a press-fitting unit 230, and a power unit 240. The positioning assembly 220 is connected to the frame 210, and the positioning assembly 220 is used for mounting the tube cover 10 and the header 20; the press-fitting unit 230 includes a first press-fitting portion 231 and a second press-fitting portion 232, and the first press-fitting portion 231 and the second press-fitting portion 232 are movably connected. The power unit 240 is connected to the frame 210, and the first press-fitting unit 231 is connected to the movable end 241 of the power unit 240.
The power portion 240 is used to drive the pressing assembly 230 to move toward the positioning assembly 220, so as to drive the collecting main 20 to move toward the direction close to the tube cover 10 after the second pressing portion 232 contacts the collecting main 20, so as to press-fit the tube cover 10 to the end of the collecting main 20.
If there is a deviation in the parallelism of both ends of the header 20 or the end surfaces of the header 20 are not parallel, when the second press-fitting portion 232 contacts the header 20, the contact manner of the second press-fitting portion 232 and the header 20 is point contact or surface contact, and at this time, since the second press-fitting portion 232 is movably connected to the first press-fitting portion 231 and the force applied to the end surface of the second press-fitting portion 232 contacting the header 20 is unbalanced, the second press-fitting portion 232 can move relative to the position contacting the header 20 under the driving of the power portion 240, so that the position of the second press-fitting portion 232 can be adjusted, the force applied to the end face of the second press-fitting portion 232 for contacting the header 20 is balanced, that is, after the second press-fitting portion 232 contacts the surface of the collecting pipe 20, the collecting pipe 20 is driven to move toward the pipe cover 10, so as to press-fit the pipe cover 10 to the end of the collecting pipe 20.
Therefore, the press-fitting mechanism 200 can adjust the contact state of the press-fitting member 230 and the header 20 when the parallelism of the two ends of the header 20 is deviated or the two end surfaces of the header 20 are not parallel, thereby ensuring the press-fitting quality of the tube cap 10.
It should be noted that, when the two ends of the collecting main 20 are parallel, because the contact manner of the press-fitting member 230 is surface contact when the press-fitting member contacts the collecting main 20 under the action of the power portion 240, and the stress of the contact surface is balanced, the position of the second press-fitting portion 232 cannot be adjusted by the movement of the power portion 240, so as to directly drive the collecting main 20 to move.
Further, in the present embodiment, when the power portion 240 is provided, the power portion 240 is an air cylinder or a hydraulic cylinder, and the movable end 241 of the power portion 240 is an end of a piston rod of the air cylinder or the hydraulic cylinder, which is far away from the cylinder body. And the moving direction of the collecting main 20 in the channel 224 is consistent with the moving direction of the movable end 241, so that the power part 240 can drive the collecting main 20 to move along the direction matched with the tube cover 10 when driving the collecting main 20 to move, thereby ensuring the quality of the press mounting of the tube cover 10.
Referring to fig. 1-4, in the present embodiment, during the process of press-fitting the tube cap 10, the press-fitting member 230 abuts against the collecting main 20 and drives the collecting main 20 to move toward the tube cap 10, so as to press-fit the tube cap 10. In this process, when the parallelism of the two ends of the header 20 is deviated or the end surfaces of the header 20 are not parallel, since the first press-fitting portion 231 and the second press-fitting portion 232 are movably connected, the position of the second press-fitting portion 232 abutting against the header 20 can be adjusted, so that the second press-fitting portion 232 is in surface contact with the header 20. Thus, when the second press-fitting portion 232 is provided, the second press-fitting portion 232 may be fitted over the first press-fitting portion 231, and an end surface of the first press-fitting portion 231 facing the second press-fitting portion 232 may be a spherical surface 233. The second press-fitting portion 232 is adapted to abut against the spherical surface 233 by an external force and to rotate relative to the first press-fitting portion 231.
Furthermore, with such an arrangement, after the second press-fitting portion 232 contacts the header 20, under the driving action of the power portion 240, the second press-fitting portion 232 can contact the spherical surface 233 of the first press-fitting portion 231, and when there is a deviation in the parallelism of the two ends of the header 20 or the end surfaces of the header 20 are not parallel, the second press-fitting portion 232 can be driven to move relative to the spherical surface 233, so as to adjust the second press-fitting portion 232 to a position in surface contact with the header 20, so that the position of the contact surface of the second press-fitting portion 232 with the header 20 can be changed relative to the spherical surface 233, and the second press-fitting portion 232 is used for surface-to-surface contact with the header 20, and the contact surface of the second press-fitting portion 232 with the header 20 is parallel to the end surface of the header 20.
Specifically, referring to fig. 1-4, when the first press-fitting portion 231 and the second press-fitting portion 232 are disposed, in the present embodiment, the second press-fitting portion 232 includes a press-fitting plate 234 and a press-fitting sleeve 235; wherein, the press-fitting sleeve 235 is sleeved on one end of the first press-fitting part 231 having the spherical surface 233; the press-fitting plate 234 is connected to the press-fitting sleeve 235, and the press-fitting plate 234 serves to restrict the movement of the first press-fitting portion 231 in a direction away from the press-fitting sleeve 235 and serves to make surface contact with the header 20. The first press-fitting portion 231 may include a connecting rod 236 and a spherical end 237, one end of the connecting rod 236 is connected to the movable end 241 of the power portion 240, and the other end of the connecting rod 236 is connected to the spherical end 237; the spherical surface 233 is disposed at an end of the spherical end 237 remote from the connecting rod 236.
That is, the cavity for accommodating the ball-shaped end 237 can be formed by the connection of the press-fitting plate 234 and the press-fitting sleeve 235, and in this way, after the press-fitting plate 234 contacts the header 20, the position of the press-fitting plate 234 can be adjusted by the contact of the press-fitting plate 234 with the ball-shaped surface 233, so that the press-fitting plate 234 rotates to a position parallel to the end surface of the header 20.
During the rotation of the press-fitting plate 234 relative to the spherical surface 233, since the press-fitting plate 234 is connected to the press-fitting sleeve 235, the movement of the press-fitting plate 234 brings the press-fitting sleeve 235 to move synchronously, and the press-fitting plate 234 and the press-fitting sleeve 235 together form a cavity for accommodating the spherical end 237, whereby the press-fitting sleeve 235 is provided with a groove 238 and a through hole 239 communicating with the groove 238 in order to allow the press-fitting sleeve 235 to rotate relative to the spherical end 237; the recess 238 for receiving the ball end 237; the through hole 239 is clearance-fitted to the connecting rod 236 and allows only the connecting rod 236 to pass through.
In summary, referring to fig. 1-4, in the present embodiment, the press-fitting member 230 includes a first press-fitting portion 231 and a second press-fitting portion 232.
The first press-fitting portion 231 includes a connecting rod 236 and a spherical end 237, one end of the connecting rod 236 is connected with the movable end 241 of the power portion 240, and the other end of the connecting rod 236 is connected with the spherical end 237; and the end of the spherical end 237 remote from the connecting rod 236 is provided with a spherical surface 233;
the second press-fit portion 232 includes a press-fit plate 234 and a press-fit sleeve 235; the press-fit sleeve 235 is provided with a groove 238 and a through hole 239 communicated with the groove 238; the press-fitting plate 234 is coupled to the press-fitting sleeve 235 and closes the opening of the recess 238 to form a space for accommodating the spherical end 237, and the coupling rod 236 is in clearance fit with the through hole 239; after the press-fitting plate 234 is connected to the press-fitting sleeve 235, the press-fitting plate 234 can be used to prevent the spherical end 237 from being separated from the press-fitting sleeve 235 from the opening direction of the groove 238, and can be used to make surface contact with the header 20 to drive the header 20 to move, and the side of the press-fitting plate 234 facing the direction of the groove 238 can be in contact with the spherical surface 233 of the spherical end 237, so that the press-fitting plate 234 can move relative to the spherical surface 233 under the driving action of the power portion 240 to adjust the contact manner of the press-fitting plate 234 and the header 20 to be surface contact.
Note that, when the through hole 239 is provided, by allowing only the connecting rod 236 to pass therethrough, the purpose is to prevent the spherical end 237 from coming off the second press-fitting portion 232 from the through hole 239; and the size of the through-hole 239 is larger than that of the connecting rod 236, in order to allow the connecting rod 236 to be clearance-fitted with the through-hole 239, in such a manner that the press-fitting sleeve 235 can leave a margin of space for the press-fitting portion to rotate relative to the connecting rod 236 by clearance-fitting the connecting rod 236 with the through-hole 239 when the press-fitting plate 234 is rotated relative to the spherical surface 233, i.e., when the second press-fitting portion 232 is adjusted in position relative to the first press-fitting portion 231 so that the second press-fitting portion 232 is in surface contact with the manifold 20.
Further, in the present embodiment, as can be seen from the above, the connecting rod 236 is in clearance fit with the through hole 239, so that, in the operation process of the press-fitting mechanism 200, in order to avoid noise generation caused by the clearance fit between the press-fitting sleeve 235 and the connecting rod 236, the press-fitting member 230 further includes an elastic ring (not shown in the form of the drawing), and the elastic ring abuts against the outer circumferential surface of the connecting rod 236 and the inner circumferential surface of the through hole 239, so as to avoid generation of loud noise caused by rigid collision between the press-fitting sleeve 235 and the connecting rod 236 by filling the clearance with the elastic ring.
Further, please refer to fig. 1-6, fig. 5 and 6 show the structure of the positioning assembly in the embodiment of the present invention; in this embodiment, during the press-fitting of the tube cap 10, the press-fitting mechanism 200 needs to position the collecting main 20 and the tube cap 10 to ensure that the collecting main 20 and the tube cap 10 are in the correct press-fitting position, so that when the positioning assembly 220 is disposed, the positioning assembly 220 may include the positioning plate 221 and the positioning frame 222.
Wherein, the positioning plate 221 is provided with a mounting groove 223 for mounting the tube cover 10; the positioning frame 222 is provided with a passage 224 for mounting the header 20; channel 224 is used to guide the movement of manifold 20 towards the direction of tube cover 10 that mates with alignment plate 221; the cap 10 in the mounting groove 223 abuts the end of the header 20 in the passage 224.
Accordingly, when the cap 10 is mounted in the mounting groove 223 and the header 20 is mounted in the passage 224, the cap 10 in the mounting groove 223 is brought into contact with the end of the header 20 in the passage 224, and then the press-fitting member 230 is driven by the power unit 240 to move, so that the cap 10 can be press-fitted to the end of the header 20, and the press-fitting quality and the press-fitting efficiency can be improved in this manner.
In order to ensure that the mounting position of the header 20 is unchanged during the press-fitting process and to facilitate the removal of the press-fitted header 20, the positioning assembly 220 further includes a movable plate 225, the movable plate 225 is configured to cooperate with the positioning frame 222 and the header 20 located in the channel 224 to limit the movement of the header 20 in the direction away from the channel 224, and the movable plate 225 is movably connected to the positioning frame 222.
Specifically, the positioning assembly 220 further includes a connecting stud 227; when the movable plate 225 is disposed, the movable plate 225 crosses the channel 224, and along the extending direction of the channel 224, the movable plate 225 is rotatably connected with one side of the positioning frame 222, and the movable plate 225 is detachably connected with the other side of the positioning frame 222. In this way, when the header 20 is matched with the channel 224, in order to prevent the installation state of the header 20 from occurring, the movable plate 225 may be driven to rotate relative to one side rotatably connected with the positioning frame 222, and when the movable plate 225 is rotated to a position connected with the other side of the positioning frame 222, the position of the movable plate 225 is rotated by connecting the movable plate 225 with the positioning frame 222, and the movable plate 225 spans the channel 224, so that the header 20 can be prevented from being separated from the channel 224.
In order to detachably connect the movable plate 225 and the positioning frame 222, so as to limit the header 20 in the channel 224 and to open the channel 224, so as to remove the header 20, a screw hole is formed at one side of the positioning frame 222 detachably connected to the movable plate 225, and the movable plate 225 is provided with a through hole 239; when the movable plate 225 is rotated to a position where it is engaged with the positioning frame 222 and the manifold 20 located in the passage 224, the connecting studs 227 pass through the through holes 239 and then are connected with the screw holes, so as to limit the rotation of the movable plate 225 relative to the positioning frame 222.
Further, in the present embodiment, a positioning table 226 abutting against the manifold 20 is further provided on a side of the movable plate 225 facing the channel 224, so as to ensure the positioning accuracy of the manifold 20 in the press-fitting mechanism 200 through the direction in which the movable plate 225 is engaged with the positioning frame 222, thereby ensuring the press-fitting quality of the tube cap 10.
