[0029] Existing threaded pipe surface spraying equipment generally has the problems of low degree of automation, large equipment size and high price. The technical solution disclosed in the utility model utilizes the mutual cooperation between the two rotating mechanisms 2, uses the electric push rod 3 to adjust the distance between the two rotating mechanisms 2, and moves the position of the spray head 14 through the electric linear screw slide 12 to realize the automatic spraying of the threaded pipe body 6.

[0030] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0031] In one embodiment of the present invention, Figures 1 to 5As shown, a threaded pipe surface spraying system includes a base 1; a slide groove 11 and an electric linear screw slide 12 arranged parallel to each other are provided on the upper surface of the base 1; a rotating mechanism 2 is fixedly provided at one end of the slide groove 11, and another rotating mechanism 2 connected to the rod head of an electric push rod 3 is provided at the other end of the slide groove 11; the electric push rod 3 can drive the connected rotating mechanism 2 to move on the slide groove 11; a vertical support rod 13 is provided on the surface of the slider of the electric linear screw slide 12, and a spray head 14 is provided at the free end of the support rod 13;

[0032] The rotating mechanism 2 includes a housing; a seat bearing is provided on the housing, and a cylindrical pipe plug 21 capable of self-rotation is provided on the seat bearing; the two cylindrical pipe plugs 21 are arranged opposite to each other and their axes coincide with each other;

[0033] A servo motor 22 is provided in the rotating mechanism 2 connected to the electric push rod 3, and the output shaft of the servo motor 22 is fixedly connected to the center of the adjacent cylindrical pipe plug 21; the control end of the servo motor 22, the control end of the electric push rod 3 and the control end of the electric linear screw slide 12 are respectively connected to the controller 5.

[0034] In this embodiment, two rotating mechanisms 2 are provided, wherein one rotating mechanism 2 is fixedly provided on the slide groove 11 and the other rotating mechanism 2 is slidably provided on the slide groove 11. A cylindrical pipe plug 21 which can be driven to rotate by a servo motor 22 is provided inside the slidable rotating mechanism 2.

[0035] In the actual application of this embodiment, the operator first uses the controller 5 to control the electric push rod 3 to retract its rod head, thereby increasing the distance between the two cylindrical pipe plugs 21, and further installs one end of the threaded tube body 6 onto the cylindrical pipe plug 21 on the fixed rotating mechanism 2, and the other end of the threaded tube body 6 onto the cylindrical pipe plug 21 on the movable rotating mechanism 2, and then uses the controller 5 to control the electric push rod 3 to extend, so that the two cylindrical pipe plugs 21 respectively fix the two ends of the threaded tube body 6.

[0036] Because both cylindrical pipe plugs 21 are mounted on seated bearings, they can rotate, thereby driving the clamped threaded pipe body 6 to rotate. Furthermore, the operator uses the controller 5 to control the servo motor 22 to rotate the connected cylindrical pipe plugs 21, thereby driving the threaded pipe body 6 to rotate. Simultaneously, the spray head 14 is connected to an external spray material supply device. The operator uses the controller 5 to control the movement of the slider of the electric linear screw slide 12, thereby driving the spray head 14 mounted on the support rod 13 to move axially along the threaded pipe body 6. At this time, the rotation of the threaded pipe body 6 and the axial movement of the spray head 14 cooperate to achieve automatic spraying of the threaded pipe surface.

[0037] In another embodiment of the present invention, Figure 2As shown, a baffle 4 is provided between the two cylindrical tube plugs 21 , and the height of the baffle 4 is lower than the height of the cylindrical tube plugs 21 .

[0038] In this embodiment, if Figure 1 As shown, the bottom of the baffle 4 is fixedly connected to the upper edge of the slide groove 11 through a support column 41 , and the length of the baffle 4 is shorter than the length of the slide groove 11 .

[0039] In this embodiment, the length of the baffle 4 is shorter than the length of the sliding groove 11 , so that the movable rotating mechanism 2 can move along the sliding groove 11 .

[0040] In this embodiment, if Figure 2 As shown, the upper surface of the baffle 4 is arc-shaped. The baffle 4 is used to prevent the spray paint from entering the chute 11 and affecting the use effect of the chute 11.

[0041] In this embodiment, the nozzle 14 is fixed to the free end of the support rod 13 via a rotating shaft, and a positioning pin for fixing the spraying direction of the nozzle 14 is provided on the rotating shaft.

[0042] The operator can change the spraying direction of the nozzle 14 by adjusting the setting position of the positioning pin to achieve a better spraying effect on the surface of the threaded pipe.

[0043] In this embodiment, the servo motor 22 is fixed in the corresponding housing via a fixing frame.

[0044] In this embodiment, the outer surface of the cylindrical pipe plug 21 is provided with a non-slip rubber layer that contacts the inner wall of the threaded pipe body 6 .

[0045] The anti-skid rubber layer is provided to improve the driving effect of the cylindrical pipe plug 21 on the threaded pipe body 6 and ensure the stability of the self-rotation of the threaded pipe body 6.

[0046] The above describes the embodiments of the present invention. However, these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Although each embodiment has been described separately, this does not mean that the measures in each embodiment cannot be used in combination to advantage.
