DETAILED DESCRIPTION

[0026] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example 1

[0028] The preferred embodiment of the positioning structure for the pipe bending hydraulic equipment provided by the utility model is as follows Figures 1 to 5 As shown: a positioning structure for a pipe bending hydraulic equipment, including an operating table 1, a first hydraulic rod 2 is fixedly connected to the surface of the operating table 1, an output end of the first hydraulic rod 2 is fixedly connected to a connecting plate 3, the top of the cross plate of the connecting plate 3 is fixedly connected to an electric telescopic rod 4, the output end of the electric telescopic rod 4 is fixedly connected to a rack 5, a gear 6 is meshed with the top of the rack 5, a transmission column 7 passes through the surface of the gear 6, a fixed plate 8 is fixedly connected to the surface of the transmission column 7, and a sliding column 9 is fixedly connected to the bottom of the cross plate of the connecting plate 3.

[0029] In this embodiment, a transversely arranged groove is provided at the top of the horizontal plate position of the connecting plate 3, and four groups of rectangular grooves are provided on the disc surface of the connecting plate 3. The rack 5 is embedded in the horizontal groove of the connecting plate 3 and is slidably connected to the connecting plate 3. Since the rack 5 is fixedly connected to the electric telescopic rod 4, when the electric telescopic rod 4 is pushed, the rack 5 will be driven to slide to the left in the sliding groove of the horizontal plate of the connecting plate 3.

[0030] In this embodiment, the connection point between the gear 6 and the connecting plate 3 is located at the center of the gear 6. The gear 6 forms a rotating structure through the rack 5. Since the gear 6 is meshed with the rack 5, when the rack 5 slides, it will drive the gear 6 to rotate clockwise around the connection point with the connecting plate 3.

[0031] In this embodiment, four groups of rectangular grooves are provided on the surface of the gear 6, and the four groups of rectangular grooves of the gear 6 are arranged at an angle. Because the surface of the gear 6 is provided with four groups of rectangular grooves arranged at an angle, and the transmission column 7 passes through the rectangular grooves of the gear 6, when the gear 6 rotates, it will drive the transmission column to slide.

[0032] In this embodiment, four groups of transmission columns 7 are provided, and the four groups of transmission columns 7 pass through the gear 6 and are embedded in the four groups of rectangular grooves of the connecting plate 3. Because the transmission columns 7 pass through the rectangular grooves of the gear 6 and are embedded in the rectangular grooves on the surface of the disk of the connecting plate 3, when the gear 6 rotates, force will be applied to the four groups of transmission columns 7, so that the four groups of transmission columns 7 move closer to the center of the gear 6 under the limit of the four groups of rectangular grooves of the connecting plate 3.

[0033] In this embodiment, four groups of fixed plates 8 are symmetrically arranged about the center of the gear 6. The four groups of fixed plates 8 are respectively fixedly connected to the four groups of transmission columns 7. When the four groups of transmission columns 7 approach the center of the gear 6, the four groups of fixed plates 8 will be driven to approach the center of the gear 6. When the four groups of fixed plates 8 move to fit the pipe, stop pushing the electric telescopic rod 4 to fix the pipe.

[0034] Example 2

[0035] On the basis of Example 1, a preferred embodiment of a positioning structure for a pipe bending hydraulic equipment provided by the present invention is as follows: Figures 1 to 5 As shown: the top of the operating platform 1 is fixedly connected to the second hydraulic rod 10, the output end of the second hydraulic rod 10 is fixedly connected to the moving column 11, the top of the moving column 11 is rotatably connected to the transmission plate 12, the bottom of the transmission plate 12 is rotatably connected to the rotating disk 13, the bottom of the rotating disk 13 is fixedly connected to two groups of limiting columns 14, the side of the rotating disk 13 is fixedly connected to the bending plate 15 through an electric telescopic plate, the top of the rotating disk 13 is rotatably connected to the concave rod 16, the side of the concave rod 16 is fixedly connected to the pressing plate 17 through an electric push rod, and the top of the operating platform 1 is located in front of the second hydraulic rod 10 and a controller 18 is arranged.

[0036] In this embodiment, the moving column 11 is arranged perpendicular to the second hydraulic rod 10, and the moving column 11 forms a moving structure through the second hydraulic rod 10. Because the moving column 11 is fixedly connected to the second hydraulic rod 10, when the second hydraulic rod 10 contracts, it will drive the moving column 11 to move to the right.

[0037] In this embodiment, the transmission plate 12 is arranged in an arc shape, and the transmission plate 12 is arranged offset from the center of the rotating disk 13. Because the transmission plate 12 is rotationally connected to the moving column 11, when the moving column 11 moves, the transmission plate 12 is pulled to the right, so that the transmission plate 12 drives the rotating disk 13 rotationally connected thereto to rotate clockwise. At this time, the limiting column 14 fixedly connected to the rotating disk 13 will slide in the annular groove of the operating table 1 and play a certain limiting role on the rotating disk 13.

[0038] In this embodiment, an annular groove matching the size of the limiting column 14 is provided on the top of the operating table 1, and the bending plate 15 is set offset from the center of the rotating disk 13. Since the bending plate 15 is connected to the rotating disk 13, when the rotating disk 13 rotates, the bending plate 15 will be driven to rotate clockwise and bend the pipe, thereby achieving the purpose of bending the pipe.

[0039] The working principle and use process of the utility model are as follows: first, the pipeline is placed into the interior of the four groups of fixed plates 8 through the concave rod 16, and then the electric telescopic rod 4 is pushed. Since the rack 5 is fixedly connected to the electric telescopic rod 4, when the electric telescopic rod 4 is pushed, the rack 5 will be driven to slide to the left in the sliding groove of the horizontal plate of the connecting plate 3. Since the gear 6 is meshed with the rack 5, when the rack 5 slides, it will drive the gear 6 to rotate clockwise around the connection point with the connecting plate 3. Because the surface of the gear 6 is provided with four groups of inclined rectangular grooves, and the transmission column 7 passes through the rectangular groove of the gear 6 and is embedded in the rectangular groove on the surface of the disc of the connecting plate 3, when the gear 6 rotates, force will be applied to the four groups of transmission columns 7, so that the four groups of transmission columns 7 move to the gear under the limit of the four groups of rectangular grooves of the connecting plate 3. 6, since the four sets of fixed plates 8 are respectively fixedly connected to the four sets of transmission columns 7, when the four sets of transmission columns 7 are close to the center of the circle of the gear 6, the four sets of fixed plates 8 will be driven to be close to the center of the circle of the gear 6. When the four sets of fixed plates 8 move to fit with the pipeline, stop pushing the electric telescopic rod 4 to fix the pipeline, and then start the first hydraulic rod 2, so that the first hydraulic rod 2 drives the connecting plate 3 to slide forward under the limit of the sliding column 9, and then drives the pipeline to slide forward. When the pipeline slides to a suitable position, stop pushing the first hydraulic rod 2, and the pipeline can be automatically sent to the bending equipment for bending, thereby achieving the purpose of automatically sending the pipeline to the bending position, and then achieving the purpose of automatic positioning, preventing errors in manual operation, and reducing the incidence of defective products;

[0040] Subsequently, the bending plate 15 and the pressing plate 17 are moved to fit with the pipeline respectively through the electric telescopic plates and electric push rods on the sides of the rotating disk 13 and the concave rod 16, so that the pressing plate 17 presses the pipeline, and then the second hydraulic rod 10 is started to shrink the second hydraulic rod 10. Because the moving column 11 is fixedly connected to the second hydraulic rod 10, when the second hydraulic rod 10 shrinks, it will drive the moving column 11 to move right. Because the transmission plate 12 is rotationally connected to the moving column 11, when the moving column 11 moves, it will pull the transmission plate 12 to the right, so that the transmission plate 12 drives the rotating disk 13 connected to it to rotate clockwise. At this time, the limiting column 14 fixedly connected to the rotating disk 13 will slide in the annular groove of the operating table 1 accordingly, and play a certain limiting role on the rotating disk 13. Since the bending plate 15 is connected to the rotating disk 13, when the rotating disk 13 rotates, it will drive the bending plate 15 to rotate clockwise together and bend the pipeline, thereby achieving the purpose of bending the pipeline.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
