Description

Technical Field

[0001] The invention relates to the technical field of aluminum pipeline welding processing, and in particular to a clamping device for grinding the weld groove of an aluminum pipeline in a module. Background Art

[0002] Aluminum pipes need to be welded with a bevel before welding. The pipe bevel is a simple bevel with an inclined surface. After the bevel processing is completed, the aluminum pipes will be stacked in one place for subsequent use. As the placement time increases, oxidation will occur at the bevel of the aluminum pipe. At this time, the oxide film on the bevel of the aluminum weld needs to be cleaned. The current traditional cleaning method is for workers to use a handheld angle grinder to cut and clean the oxide film on the bevel surface. Aluminum pipes require special clamping devices to fix them for easy cleaning.

[0003] Patent No. 202322200114.8 discloses a pipeline welding groove grinding device, which uses an outer wall limiting wheel to press against the outer wall of the pipeline, and then uses a button to adjust the position of the inner wall limiting wheel to clamp the pipe wall, and then raise and lower the grinding device to approach the pipeline groove, and then push the grinding device along the pipeline groove for grinding. Since the support rod is fixed, the device cannot be used for diameters smaller than the two outer wall limiting wheels, and when grinding, it is necessary to ensure that the space around the pipeline groove can accommodate the grinding device. The pipeline cannot be effectively fixed during grinding, so the stability of grinding is not high. Summary of the invention

[0004] The technical problem to be solved by the present invention is: a clamping device for grinding the weld groove of an aluminum pipe in a module, which can simultaneously meet the requirements of clamping the pipe in horizontal and vertical states, facilitates different grinding states, and improves flexibility.

[0005] In order to solve the above technical problems, the technical solution of the present invention is: a clamping device for grinding the weld bevel of aluminum pipes in modules, comprising a clamping platform, a horizontal clamping station and a vertical clamping station are arranged on the clamping platform, the clamping platform is located on the horizontal clamping station and is rotatably installed with a lower rotating roller group supporting the rolling pipe, the clamping platform is also fixedly installed with a horizontal clamping support frame, an upper rotating roller group for pressing down the pipe is lifted and lowered on the horizontal clamping support frame, the lower rotating roller group is driven to rotate by a driving rotation power device, the upper rotating roller group is driven to lift and lower by a lifting power device, the clamping platform is located on the vertical clamping station and is rotatably installed with a clamping chuck, and the clamping chuck is driven to rotate by a rotary power device.

[0006] As a preferred solution, the lower rotating roller group comprises a lower active rotating roller and a lower driven rotating roller, and the lower active rotating roller and the lower driven rotating roller are rotatably mounted on the clamping platform through a rotating roller support frame, the lower active rotating roller is located on one side below the pipeline, and the lower driven rotating roller is located on the other side below the pipeline, and the driving rotating power device drives the lower active rotating roller to rotate through a synchronous belt transmission device.

[0007] As a preferred solution, the upper rotating roller group includes upper rotating rollers located on both sides above the pipeline, the lifting power device includes a lifting motor, the lifting motor is fixedly mounted on a horizontal clamping support frame, the guide rod of the lifting motor is connected to a lifting drive rod that passes downward through the horizontal clamping support frame, a pressure plate is connected below the lifting drive rod, and the upper rotating rollers are also mounted on both sides of the pressure plate through a rotating roller support frame.

[0008] As a preferred solution, the lower active rotating roller, the lower driven rotating roller and the upper rotating roller are all divided into several sections of rotating rollers, and the short rotating rollers are connected by connecting shafts passing through the centers of the rotating rollers.

[0009] As a preferred solution, the rotating roller support frame of the lower driven rotating roller is detachably mounted on the clamping platform by screw connection, and the clamping platform is provided with corresponding threaded holes at the horizontal clamping station.

[0010] As a preferred solution, the lifting drive rod is hingedly connected to the pressing plate.

[0011] As a preferred solution, a support platform is provided under the clamping chuck, and the support platform is rotatably installed on the clamping platform located on the vertical clamping station through a rotating bearing. A driven gear is connected under the clamping platform, and the driven gear is meshed with a driving gear rotatably installed under the clamping platform. The rotary power device drives the driving gear to rotate.

[0012] After adopting the above technical scheme, the effect of the present invention is as follows: since the clamping device for grinding the weld groove of the aluminum pipe in the module includes a clamping platform, the clamping platform is provided with a horizontal clamping station and a vertical clamping station, the clamping platform is located on the horizontal clamping station and is rotatably installed with a lower rotating roller group supporting the rolling pipe, the clamping platform is also fixedly installed with a horizontal clamping support frame, and the upper rotating roller group for pressing down the pipe is lifted and installed on the horizontal clamping support frame, the lower rotating roller group is driven to rotate by a driving rotation power device, and the upper rotating roller group is driven to lift and lower by a lifting power device, and the clamping platform is located at the vertical clamping station. A clamping chuck is rotatably installed on the workstation, and the clamping chuck is driven to rotate by a rotary power device; the pipeline is placed horizontally on the lower rotating roller group, so that it can rotate on the lower rotating roller group, and then the lifting power device drives the upper rotating roller group to descend, pressing down the pipeline, and at the same time the pipeline is also driven by the rotating power device to drive the lower rotating roller group to rotate, so that it can be effectively fixed and rotate stably; the pipeline can be directly installed vertically on the clamping chuck, which can also complete the fixation and stable rotation, which can facilitate subsequent cutting and cleaning; the clamping device can simultaneously meet the clamping of the pipeline in the horizontal and vertical states, facilitate different grinding states, and improve flexibility.

[0013] Furthermore, since the lower rotating roller group is respectively a lower active rotating roller and a lower driven rotating roller, the lower active rotating roller and the lower driven rotating roller are rotatably installed on the clamping platform through a rotating roller support frame, the lower active rotating roller is located on one side below the pipeline, and the lower driven rotating roller is located on the other side below the pipeline, and the driving rotating power device drives the lower active rotating roller to rotate through a synchronous belt transmission device; the lower active rotating roller and the lower driven rotating roller can make the pipeline fall between the rotating rollers, effectively support the rotation and avoid the pipeline from sliding out during rotation, thereby improving practicality.

[0014] Furthermore, since the upper rotating roller group includes upper rotating rollers located on both sides above the pipeline, the lifting power device includes a lifting motor, and the lifting motor is fixedly mounted on a horizontal clamping support frame. The guide rod of the lifting motor is connected with a lifting drive rod that penetrates downwardly through the horizontal clamping support frame, and a pressure plate is connected below the lifting drive rod. The upper rotating roller is also mounted on both sides of the pressure plate through a rotating roller support frame. The upper rotating roller is driven down by the lifting motor to press the pipeline, so that the upper rotating roller, the lower active rotating roller, and the lower driven rotating roller can all fit with the pipeline, thereby completing the restriction on the rotation of the pipeline and further ensuring the stability of subsequent cutting and cleaning.

[0015] Furthermore, since the lower active rotating roller, the lower driven rotating roller and the upper rotating roller are divided into several sections of rotating rollers, the short rotating rollers are connected through the connecting shaft passing through the center of the rotating rollers; the several sections of rotating rollers can reduce the contact area with the pipeline without affecting the support and rotation, thereby improving the stability of the pipeline rotation.

[0016] Furthermore, since the rotating roller support frame of the lower driven rotating roller is detachably mounted on the clamping platform by screw connection, a corresponding threaded hole is provided on the clamping platform at the horizontal clamping station; in this way, the spacing between the lower driven rotating roller and the lower active rotating roller can be changed to adapt to pipes of different sizes and has a wide range of applications.

[0017] Since the lifting drive rod is hingedly connected to the pressing plate, when the distance between the lower active rotating roller and the lower driven rotating roller is changed, the pressing plate can swing to ensure the accuracy of pressing down the pipeline and stable rotation.

[0018] Furthermore, since a support platform is provided under the clamping chuck, the support platform is rotatably installed on the clamping platform located on the vertical clamping station through a rotating bearing, a driven gear is connected under the clamping platform, and the driven gear is meshed with a driving gear rotatably installed under the clamping platform, and the rotary power device drives the driving gear to rotate; when the clamping chuck clamps the pipeline, the rotary power device drives the support platform to rotate, and then the pipeline can be rotated vertically, with a simple structure and reliable clamping.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below through specific examples.

[0022] like Figures 1 to 3As shown, a clamping device for grinding the weld groove of aluminum pipes in a module comprises a clamping platform 1, on which a horizontal clamping station 2 and a vertical clamping station 3 are provided, the clamping platform 1 is located on the horizontal clamping station 2 and is rotatably installed with a lower rotating roller group for supporting a rolling pipe, the clamping platform 1 is also fixedly installed with a horizontal clamping support frame 4, on which an upper rotating roller group 11 group for pressing down the pipe is lifted and lowered, the lower rotating roller group is driven to rotate by a driving rotation power device, and the upper rotating roller group 11 group is driven to lift and lower by a lifting power device, the clamping platform 1 is located on the vertical clamping station 3 and is rotatably installed with a clamping chuck 5, and the clamping chuck 5 is driven to rotate by a rotary power device.

[0023] In this embodiment, the lower rotating roller group is respectively a lower active rotating roller 6 and a lower driven rotating roller 7, the lower active rotating roller 6 and the lower driven rotating roller 7 are rotatably mounted on the clamping platform 1 through a rotating roller support frame 14, the lower active rotating roller 6 is located on one side below the pipeline, and the lower driven rotating roller 7 is located on the other side below the pipeline, and the driving rotating power device drives the lower active rotating roller 6 to rotate through a synchronous belt 10 transmission device; on the clamping platform 1, the corresponding lower active rotating roller 6 and the lower driven rotating roller 7 are supported by the rotating roller support frame 14, which are respectively located on both sides of the pipeline, so that the pipeline falls between the two, effectively supporting the rotation and preventing the pipeline from sliding out during rotation, thereby improving practicality; the driving power device is a driving motor 8, which is fixedly mounted on the clamping platform 1, and then a synchronous pulley 9 is provided on the output shaft of the driving motor 8 and the lower active rotating roller 6, and then the synchronous belt 10 can be used for transmission, and the synchronous pulley 9 on the driving motor 8 is larger than the synchronous pulley 9 on the lower active rotating roller 6, thereby improving the rotation speed of the lower active rotating roller 6.

[0024] Furthermore, the upper rotating roller 11 group includes upper rotating rollers 11 located on both sides above the pipeline, and the lifting power device includes a lifting motor 12. The lifting motor 12 is fixedly mounted on the horizontal clamping support frame 4, and the guide rod of the lifting motor 12 is connected to a lifting drive rod 21 that penetrates downwardly through the horizontal clamping support frame 4. A pressure plate 13 is connected below the lifting drive rod 21, and the upper rotating roller 11 is also installed on both sides of the pressure plate 13 through a rotating roller support frame 14; the upper rotating roller 11 is installed on both sides of the pressure plate 13 through the rotating roller support frame 14, thereby also corresponding to both sides of the pipeline. By driving the lifting drive rod 21 to rise and fall through the lifting motor 12, the pressure plate 13 is driven to rise and fall, thereby controlling the upper rotating roller 11 and the lower active rotating roller 6 and the lower driven rotating roller 7 to press the pipeline, thereby completing the restriction on the rotation of the pipeline and further ensuring the stability of subsequent cutting and cleaning.

[0025] like Figure 2As shown, the lower active rotating roller 6, the lower driven rotating roller 7 and the upper rotating roller 11 are divided into several sections of rotating rollers, and the short rotating rollers are connected by connecting shafts 15 passing through the centers of the rotating rollers. Since the pipeline is long, it is impossible to ensure that the outer wall is smooth during processing, thereby reducing the contact area with the pipeline, while not affecting the rotation transmission, ensuring that the pipeline rotates stably and reliably.

[0026] Furthermore, the rotating roller support frame 14 of the lower driven rotating roller 7 is detachably mounted on the clamping platform 1 by means of screw connection, and a corresponding threaded hole is provided on the clamping platform 1 at the horizontal clamping station 2; by moving the rotating roller support frame 14 to the corresponding threaded hole, the spacing between the lower driven rotating roller 7 and the lower active rotating roller 6 can be effectively changed, which can adapt to pipes of different sizes and has a wide range of applications.

[0027] The lifting drive rod 21 is hingedly connected to the pressure plate 13, and the pressure plate 13 can be conveniently swung along the horizontal direction perpendicular to the pipeline axis. In this way, when the distance between the lower active rotating roller 6 and the lower driven rotating roller 7 is changed, the pressure plate 13 can be deflected to ensure the accuracy of pressing down the pipeline and stable rotation.

[0028] like Figure 3 As shown, a support platform 16 is provided under the clamping chuck 5, and the support platform 16 is rotatably mounted on the clamping platform 1 located on the vertical clamping station 3 through a rotating bearing 17. A driven gear 18 is connected under the clamping platform 1, and the driven gear 18 is meshed with a driving gear 19 rotatably mounted under the clamping platform 1, and the rotary power device drives the driving gear 19 to rotate; the rotary power device includes a rotary motor 20, and the driving shaft of the rotary motor 20 is connected to the driving gear 19 and rotatably mounted under the clamping platform 1, and meshed with the driven gear 18 to ensure that the clamping chuck 5 rotates stably, and the transmission can also be stable and reliable. The driving gear 19 is larger than the driven gear 18, so that the clamping chuck 5 can be driven to rotate more conveniently and faster. The clamping chuck 5 is a four-jaw chuck, which is an existing structure on the market, and therefore it is not described in detail in the text.

[0029] The working principle of this embodiment is as follows: the pipeline is placed horizontally between the lower active rotating roller 6 and the lower driven rotating roller 7, and then the lifting motor 12 drives the pressure plate 13 to descend, and the upper rotating roller 11 contacts and presses the pipeline, and then the driving motor 8 transmits the transmission to the lower active rotating roller 6 through the synchronous belt 10, and the lower active rotating roller 6 drives the pipeline to rotate, so that the pipeline starts to rotate; the pipeline can also be placed vertically on the clamping chuck 5, the claws on the clamping chuck 5 are opened, and the pipeline is clamped vertically. After the clamping is completed, the rotary motor 20 drives the active gear 19 to rotate and drives the driven gear 18 to rotate, so that the support platform 16 rotates, and the clamped pipeline thus rotates vertically.

[0030] The above-described embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Various modifications and alterations to the technical solutions of the present invention without departing from the spirit of the present invention should fall within the scope of protection defined by the claims of the present invention.
