Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1-3, the utility model provides a pipe fitting anomaly detection device, including test channel 1 and detecting element 2. The detection channel 1 is used for allowing pipe fittings to pass through, and the detection unit 2 is used for detecting whether the width of the detection channel 1 changes or not.
When the pipe passes through the detection channel 1, if the detection unit 2 detects that the width of the detection channel 1 is increased, the detection unit 2 transmits a signal to indicate that the pipe is not abnormal; when the pipe passes through the detection channel 1, if the detection unit 2 detects that the width of the detection channel 1 is unchanged, the detection unit 2 does not transmit a signal to indicate that the pipe is abnormal.
Specifically, the tube member is an air conditioning capillary tube having a boss projecting radially thereon. The diameter of the capillary at the location of the boss is thus larger than at the remaining locations. When the width of the detection channel 1 is unchanged, the detection channel is matched with the diameters of the positions of the capillary except the boss, so that when the capillary passes through the detection channel 1, if the capillary is not abnormal (namely, the capillary has the boss thereon), the width of the detection channel 1 is increased by the boss of the capillary, the detection unit 2 detects the change and sends a signal to downstream equipment to indicate that the capillary is not abnormal, and the downstream equipment operates normally; on the contrary, if the capillary tube has an abnormality (i.e. no bump is formed thereon), the diameter of the capillary tube is uniform, the width of the detection channel 1 is not changed, the detection unit 2 does not send a signal to the downstream equipment when detecting no change, and the downstream equipment is automatically stopped.
In one embodiment, the detection channel 1 is formed by a space between a first wheel 11 and a second wheel 12 arranged side by side, the second wheel 12 being movable in its radial direction under the influence of an external force to vary the width of the detection channel 1.
Specifically, the first wheel 11 and the second wheel 12 can rotate by taking the axis thereof as a rotating shaft, and the rotating directions of the first wheel 11 and the second wheel 12 are opposite, so that when the capillary tube passes through the detection channel 1 between the first wheel 11 and the second wheel 12, the capillary tube can be driven to move along the axial direction thereof, and each part of the capillary tube can pass through the detection channel 1.
The first wheel 11 has no freedom of radial displacement and the second wheel 12 has freedom of radial displacement. Therefore, when the capillary tube passes through the detection channel 1 between the first wheel 11 and the second wheel 12, if the capillary tube has a boss, the boss pushes the second wheel 12 to move in the radial direction, so that the width of the detection channel 1 becomes larger. If the capillary tube is free of projections, the capillary tube will pass smoothly through the detection channel 1 between the first wheel 11 and the second wheel 12 without moving the second wheel 12 in its radial direction.
In some embodiments, the detecting unit 2 includes a sensor 21 and a connecting block 22, a first end of the connecting block 22 is connected to the second wheel 12, and the second wheel 12 moves along the radial direction thereof to move a second end of the connecting block 22 away from or block a detecting position of the sensor 21 so that the sensor 21 emits or does not emit a signal.
As mentioned above, the radial movement of the second wheel 12 indicates that the capillary has a boss, which moves the second end of the connecting block 22 away from the detection position of the sensor 21 to make the sensor 21 emit a signal, so that the downstream equipment can operate normally; the second wheel 12 does not move to indicate that no boss is arranged on the capillary tube, and the second end of the connecting block 22 does not move and shields the detection position of the sensor 21 so that the sensor 21 does not emit a signal, thereby stopping the operation of the downstream equipment.
Specifically, the second wheel 12 is connected to a first end of the connecting block 22 through a slider 13, and a first spring 15 is connected to the slider 13, and the first spring 15 is used for restoring the second wheel 12. One end of the first spring 15 is connected to a base 14 described below, and the other end is connected to the slider 13, and when the external force on the second wheel 12 is removed after the second wheel 12 is used, the first spring 15 drives the slider 13 to return the second wheel 12 to the initial position.
The device further comprises a base 14, and the first wheel 11, the second wheel 12 and the detection unit 2 are all arranged on the base 14. The first end of the connecting block 22 is rotatably connected to the base 14, and when the second wheel 12 drives the sliding block 13 to move, the connecting block 22 is rotated on the base 14 to leave or block the detection position of the sensor 21.
A bearing 26 is disposed between the first end of the connecting block 22 and the base 14 to facilitate rotation of the connecting block 22. When the connecting block 22 is rotated in a direction away from the sensor 21, the second end of the connecting block 22 is away from the detection position of the sensor 21; when the connection block 22 is rotated (i.e., reset) in a direction to approach the sensor 21, the second end of the connection block 22 blocks the detection position of the sensor 21.
The first end of the connection block 22 is also connected to a second spring 15, and the second spring 15 is used to restore the connection block 22. One end of the second spring 15 is connected to a first end of the connection block 22, and the other end is connected to the base 14, so that the connection block 22 is rotated in a direction to approach the sensor 21.
The sliding block 13 and the second wheel 12 are respectively disposed on the opposite surfaces of the base 14, the second wheel 12 includes a second wheel disc 121 and a second connecting rod 122 disposed on the axis direction of the second wheel disc 121, and the second connecting rod 122 penetrates through the base 14 and then is connected to the second end of the sliding block 13.
The first end of the connecting block 22 is further connected to a first connecting rod 25, and the first connecting rod 25 penetrates through the base 14 and is connected to the first end of the sliding block 13.
Therefore, when the second wheel 121 moves radially, the second connecting rod 122 penetrating through the axis thereof pushes the slider 13 to move, and then the first connecting rod 25 moves and drives the connecting block 22 to rotate away from the detection position of the sensor 21. After the inspection of one pipe is completed, the first spring 15 and the second spring 23 respectively restore the second disc 121 and the connection block 22 to perform the inspection of the next pipe.
The first wheel 11 comprises a first wheel 11 disc, and annular grooves 17 are formed in the outer walls of the first wheel 11 disc and the second wheel 12 disc, so that the axial movement of the pipe fitting is facilitated.
A material guide cylinder 16 is arranged on one side of the detection channel 1. The guide cylinder 16 has an axial direction corresponding to the axial direction of the pipe to receive the pipe after the inspection.
In other embodiments, the detection unit 2 is a displacement detector for detecting a displacement of the second wheel 12. When the second wheel 12 is displaced radially, the detection unit 2 is able to detect its displacement and emit a signal.
While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. The present invention is not limited to the particular embodiments disclosed herein, but encompasses all technical solutions falling within the scope of the claims.
