[0026] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0027] The same or similar numbers in the drawings of the embodiments of the present invention correspond to the same or similar parts; in the description of the present invention, it should be understood that if the terms "upper", "lower", "left", "right", "inner", "outer", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0028] like Figure 1-4 As shown, one specific embodiment of a drill bit welding auxiliary rolling device includes a horizontally installed base 1. In this specific embodiment, the base 1 is welded by an I-beam. At least two sets of bearing groups 2 are bolted to the base 1 in front and back correspondences. Each set of bearing groups 2 includes two bearings 201 installed in left and right correspondences. The rotation direction of the two bearings 201 in the same set of bearing groups 2 is parallel to the connecting line of the two bearings 201, so that a cylindrical drill bit can be placed above multiple sets of bearing groups 2, and the drill bit is supported by the bearing 201, so that the drill bit can roll above the bearing 201 to adjust the angle of the drill bit.

[0029] In order to enable the drill bit to switch between rolling and stopping states when adjusting the angle, a stop device 3 is installed on the base 1. Specifically, the stop device 3 includes four support rods 301 vertically fixed on the base 1 and a support seat 302 fixed on the top of the support rod 301. A swing seat 303 is hinged on the support seat 302, so that the swing seat 303 can swing left and right on the support seat 302. The swing seat 303 includes a driving arm 3031, a first driven arm 3032 and a second driven arm 3033. The driving arm 3031 faces downward, and the lower end of the driving arm 3031 is arc-shaped. A movable sleeve 304 that can move up and down is sleeved on the support rod 301, and a driving plate 305 is connected between each movable sleeve 304. A compression spring 306 is supported between the bottom of the driving plate 305 and the top of the base 1. The driving plate 305 has an upward elastic force under the action of the compression spring 306. The lower end of the driving arm 3031 is pressed on the driving plate 305, and the driving arm 3031 with an arc-shaped end is easy to move on the driving plate 305. When the driving arm 3031 deflects to one side, the driving plate 305 moves the driving arm 3031 upward to the deflected side under the elastic force of the compression spring 306. The first driven arm 3032 and the second driven arm 3033 of the swing seat 303 extend to the left and right sides respectively after extending into the drill bit. The end of the first driven arm 3032 is equipped with a pressure wheel 3034, and the end of the second driven arm 3033 is equipped with a pressure block 3035. The compression spring 306 provides an upward elastic force for the driving arm 3031. When the driving arm 3031 deflects to one side, the first driven arm 3032 presses downward, so that the pressure wheel 3034 is pressed on the inner wall of the drill bit. The rotation direction of the pressure wheel 3034 is parallel to the rotation direction of the bearing 201, and the drill bit can rotate at this time; when the driving arm 3031 deflects to the other side, the second driven arm 3033 presses downward, so that the pressure block 3035 is pressed on the inner wall of the drill bit. The material of the pressure block 3035 is rubber, which increases the friction between the pressure block 3035 and the drill bit, and the drill bit stops rotating at this time.

[0030] In order to facilitate switching of the left and right tilting directions of the swing seat 303, a swing arm 3036 is fixed above the swing seat 303. The swing arm 3036 and the driving arm 3031 extend in opposite directions, that is, the swing arm 3036 extends upward, and the length of the swing arm 3036 is 2-3 times the length of the driving arm 3031, so that the torque of the swing arm 3036 is greater than the torque of the driving arm 3031, which saves effort when moving the swing arm 3036.

[0031] More specifically, in this specific embodiment, two groups of bearing groups 2 are installed on the base 1 at intervals in the front and back, and the position of one group of bearing groups 2 can be adjusted in the front and back to accommodate drill bits of different lengths.

[0032] The action process is as follows:

[0033] Swing the swing arm 3036 to the middle position by hand, place the drill bit to be repaired on the bearing group 2, and make the first driven arm 3032 and the second driven arm 3033 located inside the drill bit to be repaired, then move the swing arm 3036 so that the pressure wheel 3034 of the first driven arm 3032 presses on the inner wall of the drill bit to be repaired, roll the drill bit to be repaired to a predetermined angle, then move the swing arm 3036 so that the pressure block 3035 of the second driven arm 3033 presses on the inner wall of the drill bit to be repaired to achieve positioning of the drill bit to be repaired, and start repair.

[0034] Those skilled in the art will readily appreciate other embodiments of the present invention after considering the specification and practicing the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present invention, which follow the general principles of the present invention and include common knowledge or customary technical means in the art that are not disclosed in the present invention.
