DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0018] Embodiment 1, please refer to Figures 1-3 ​​The utility model provides a technical scheme: a kind of beveling device before welding tank body, including the roller mechanism 1 for driving the rotation of the tank body 2 in horizontal posture;Further include the trolley 3 with wheel 31 in bottom;The vertical column 32 is fixedly connected on the trolley 3;The cutter head 4 is installed on the one side of the upper portion of the vertical column 32;The cutter holder 5 is slidably connected on the side of the cutter head 4;The blade 6 for cutting the rim of the tank body 2 is fixedly connected on the cutter holder 5;Screw hole 52 is equipped in the center of the cutter holder 5;Screw rod 7 is threadedly connected in the screw hole 52, and the screw rod 7 is rotatably connected on the cutter head 4, for driving the cutter holder 5 to translate when the screw rod 7 rotates;Hand wheel 71 is connected to the end of the screw rod 7, for driving the screw rod 7 to rotate.

[0019] When using, the initial state is that the roller mechanism 1 supports the lower portion of the tank body 2 in horizontal posture, and the roller rotates to drive the tank body 2 to rotate. First, the trolley 3 is shifted to the rim of the tank body 2 and then stopped;The cutter head 4, the cutter holder 5 and the blade 6 are installed, so that the blade 6 is close to the rim on one side of the tank body 2, and the preferred position is that the rim of the tank body 2 at the blade 6 moves downward;The hand wheel 71 is rotated to drive the screw rod 7 to rotate, the screw rod 7 drives the cutter holder 5 to translate, and the translation amount of the cutter holder 5 is the feed amount. The blade 6 cuts the rim of the tank body 2 to form a bevel. Therefore, the driving force for cutting comes from the friction between the roller mechanism 1 and the tank body 2, and the feed amount of the blade 6 comes from the screw rod 7. It can be seen that the device replaces manual grinding, has high efficiency, saves time and labor, ensures the quality of the processed bevel, and the trolley 3 can be moved after processing is completed, does not occupy the site, and is convenient to use.

[0020] Among them, the sliding connection mode of the exemplary cutter holder 5 and the cutter head 4 is that the dovetail groove 41 is formed on the cutter head 4, and the dovetail head 51 is arranged at one end of the cutter holder 5 and inserted into the dovetail groove 41, for slidably connecting the cutter holder 5 on the side of the cutter head 4.

[0021] In order to facilitate temporary fixation of the trolley 3, a supporting leg 33 is threadedly connected at each corner of the trolley 3. When the trolley 3 reaches the processing position, the supporting leg 33 is rotated to extend until the wheel 31 is suspended, and then adjusted one by one until the trolley 3 is leveled, the trolley 3 is fixed by the supporting leg 33, and shaking is avoided.

[0022] In order to facilitate the shifting of the trolley 3, the handrail pipe 34 is fixedly connected to the trolley 3, for pushing the trolley 3 to move, and manpower is used, which reduces the equipment cost.

[0023] In order to replace the cutter head 4, at least one group of mounting holes 35 is formed on the upper portion of the vertical column 32, a group of connecting holes are formed on the cutter head 4, and the screw assembly 36 penetrates the mounting holes 35 and the connecting holes to detachably install the cutter head 4 on the vertical column 32. The cutter head 4 and the vertical column 32 are manufactured separately, which is convenient for processing and maintenance.

[0024] More preferably, the mounting holes 35 on the column 32 have multiple groups arranged at intervals up and down, for the installation height of the cutter head 4 to be adjustable. It can adapt to the processing of tanks 2 of different diameters, and has better adaptability.

[0025] In order to connect the screw rod 7 with the cutter head 4, the exemplary mode is that one side of the cutter head 4 is fixedly connected with a mounting seat 8; the mounting seat 8 is provided with a through hole 81; the middle part of the screw rod 7 is inserted into the through hole 81; the screw rod 7 is rotatably connected with the cutter head 4; a pair of convex rings 72 are fixedly connected with the screw rod 7 and are attached to the left and right sides of the mounting seat 8, for limiting the axial movement of the screw rod 7. It can be seen that when the screw rod 7 rotates, the screw rod 7 does not move axially, and only the cutter holder 5 moves.

[0026] In order to facilitate the replacement of the blade 6, the blade 6 is mounted on the cutter holder 5 through a pair of screws 61, for the blade 6 to be detachable. The replacement of the blade 6 can also process different shapes of grooves, and the replacement of the new blade 6 after the blade 6 is worn can ensure the processing efficiency.

[0027] The embodiment has the advantages that the device replaces manual grinding processing, has high efficiency, saves time and effort, ensures the quality of the processed groove, the trolley 3 is movable, can be moved away after the processing is completed, does not occupy the site, and is convenient to use.

[0028] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
