Fig. 1-5 show a multi-angle detection device for pressure pipes according to a preferred embodiment of the present invention, including:
a sun gear 1; a first motor 2 in driving connection with the sun gear 1; a planet carrier 3 which is arranged around the periphery of the sun gear 1 and is provided with an inner gear ring 31; a planet wheel 4 in meshing transmission with the sun wheel 1 and the inner gear ring 31; and a rack 5 which is pivotally connected with the planet wheel 4 and rotates around the axis of the sun wheel 1 along with the planet wheel 4, wherein the rack 5 is provided with a guide groove 51 on the opposite surface of the tooth surface.
Referring to fig. 4, the multi-angle detection device of the pressure pipeline further includes a ring 6 fixed to the planet carrier 3, the ring 6 and the planet carrier 3 are coaxially arranged, the outer diameter of the ring 6 is equal to the outer diameter of the planet carrier 3, and an annular groove 61 is formed in the inner ring wall surface of the ring 6 around the axis of the ring; the rack 5 is fixedly connected with a guide block 53, and the guide block 53 is inserted into the annular groove 61 and can move circularly around the groove direction of the annular groove 61.
The multi-angle detection device of the pressure pipeline further comprises a detection mechanism 7, wherein the detection mechanism 7 comprises a linkage support 71, a second motor 72 fixed on the linkage support 71, a gear 73 in driving connection with the second motor 72, and a detection lens 74 fixed on the linkage support 71; the linkage bracket 71 is matched with the guide groove 51 and can move along the length direction of the guide groove 51, and the gear 73 is matched with the rack 5; the detection lens 74 is closer to the axis of the sun gear 1 than the gear 73.
It will be appreciated that the planet carrier 3 may be fixed to the ground. In operation, the sun gear 1 is driven to rotate by the first motor 2, so that the planet gear 4 can rotate around the axis of the sun gear 1, and the rack 5 pivotally connected to the planet gear 4 can rotate around the axis of the sun gear 1 synchronously, that is, the detection lens 74 can make circular motion finally. Moreover, the guide block 53 is guided and limited by the annular groove 61, so that the detection lens 74 is ensured to be closer to the axis of the sun gear 1 than the gear 73 in the rotating process, and the detection lens 74 can work normally. The second driving motor drives the gear 73 to move along the longitudinal direction of the rack 5, so that the detection lens 74 can perform translational motion along the direction of the rack 5 in addition to rotation. Thus, when the pressure pipe 8 is detected, the pressure pipe 8 is fixed to the machine tool so that the axis thereof is collinear with the axis of the sun gear 1, and the pressure pipe can be detected in a multi-angle and all-around manner by the detection lens 74. Compared with the patent application with the application number of CN201821223404.7, the detection lens 74 can thoroughly realize omnibearing detection.
It should be explained here that, obviously, the planet wheel 4 makes a circular motion, so as to drive the rack 5 to make a circular motion, so that the linkage bracket 71 makes a circular motion, that is, the purpose of making the detection lens 74 make a circular motion is achieved. Then, the gear 73 is driven to rotate by the second motor 72, so that the linking bracket 71 moves in the longitudinal direction of the rack 5, and the function that the detection lens 74 can move in the longitudinal direction of the rack 5 is realized. After the two motions are combined, the detection lens 74 can perform short-distance detection on any position of the pressure pipeline 8, that is, a multi-angle and omnibearing detection function is realized. Further, as the rack 5 is provided with the guide groove 51 on the opposite surface of the tooth surface thereof, and the linkage bracket 71 is matched with the guide groove 51 on the rack 5; that is, the rack 5 is clamped by the linking support 71 and the gear 73, so that the linking support 71 is ensured not to fall down, the linking support 71 is ensured to move along the length direction of the rack 5, and finally, the function that the detection lens 74 moves along the length direction of the rack 5 on the basis of realizing rotation is realized.
Preferably, a pivot shaft 52 is fixed at the end of the rack 5, and the pivot shaft 52 is pivotally connected with the planet wheel 4. It can be understood that, by pivotally connecting planet wheel 4 through pivot shaft 52, it is ensured that when planet wheel 4 rotates, pivot shaft 52 can rotate relative to planet wheel 4, and further, when guide block 53 makes a circular motion along the groove of annular groove 61, pivot shaft 52 makes a self-rotation motion (i.e. tooth surface of rack 5 always faces outward or always faces inward when rack 5 makes a circular motion around the axis of sun wheel 1), so as to ensure that in any case, detection lens 74 is closer to the axis of sun wheel 1 than gear 73, so as to ensure that detection lens 74 works normally. Wherein, the guide block 53 is preferably fixed (e.g., welded, integrally formed, etc.) at the end of the pivot shaft 52 in the present embodiment; alternatively, the guide block 53 may be fixed on the main body of the rack 5, and in this case, the connection relationship between the pivot shaft 52 and the rack 5 may be that the pivot shaft 52 is pivotally connected to the end of the rack 5, besides the fixed connection manner.
As a further preferred arrangement, a wheel may be added to the guide block 53 to make a rolling connection with the annular groove 61, instead of a sliding friction connection.
Preferably, the linking bracket 71 includes a frame body 711, and a roller 712 pivotally connected to the frame body 711, the roller 712 being disposed in the guide groove 51 and capable of rolling along the groove direction of the guide groove 51. It can be understood that the guide groove 51 is fixedly connected by the roller 712, so that the resistance can be reduced, and the operation process of the link bracket 71 can be smoother. Of course, the interlocking bracket 71 may be slidably connected to the guide groove 51 in addition to this arrangement. Further, two first bearings 713 are embedded in the frame body 711, the roller 712 is pivotally connected with a support shaft 714 which is collinear with the axis of the roller, and two ends of the support shaft 714 are respectively pivotally connected with one of the first bearings 713; obviously, the first bearing 713 is used for supporting, so that the friction coefficient can be greatly reduced, and the moving support can run more accurately and stably. Wherein, the supporting shaft 714 can be fixedly connected with the roller 712 besides being pivotally connected with the roller 712.
Preferably, a second bearing 715 is embedded in the frame body 711, and an output shaft of the second motor 72 passes through the second bearing 715 and is fixedly connected with the gear 73; the movement of the gear 73 is made smoother by the second bearing 715 supporting the output shaft of the second motor 72.
As a preferred implementation, the gear 73 is closer to the axis of the sun gear 1 than the tooth surface of the rack 5. With this arrangement, the tooth surface of the rack 5 can be prevented from facing outward, i.e., the tooth surface of the rack 5 is always facing inward, so that the meshing portion of the gear 73 and the rack 5 is protected from being worn by accidental rigid collision.
Preferably, the sun gear 1, the planet carrier 3 and the planet gear 4 are respectively provided with two gears and are respectively arranged on two sides of the rack 5 in an opposite way; the two planet wheels 4 are respectively pivotally connected with one end part of the rack 5.

And the other end of the rack 5 can be prevented from being hung for a long time to cause bending accidents through the support of the two planet carriers 3.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
