Description

Technical Field

[0001] This utility model relates to the field of drill bit processing technology, specifically to a tooling for welding a wear-resistant layer onto the tooth palm shaft of a single roller cone drill bit. Background Technology

[0002] Single-cone drill bits are widely used in pile and column construction. The quality of a single-cone drill bit depends on the wear resistance of its teeth; applying a wear-resistant layer to the tooth shaft is the best way to improve its quality.

[0003] like Figure 5 and Figure 6 As shown, the palm shaft needs to be welded in the three shaded areas shown in a, b, and c to improve wear resistance. Specifically, areas a and b are the shaft welding areas, and area c is the palm welding area. However, existing drill bit fixing devices, such as the fixing device for PDC drill bit welding disclosed in CN210099382U, include a housing. Inside the housing, a clamping gear driven by a pedal-type gear transmission mechanism is rotatably arranged. The clamping gear has a clamping hole at its center, and multiple telescopic clamping teeth are arranged circumferentially on the inner wall of the clamping hole. By inserting the connector of the PDC drill bit into the clamping hole through a through hole in the side wall of the housing, the drill bit is clamped and fixed by the multiple telescopic clamping teeth. However, such devices have the problem of inconvenience in adjusting the operating angle during actual operation. This is very inconvenient when welding different areas of the palm shaft.

[0004] In view of this, the present invention proposes a welding fixture for applying a wear-resistant layer to the tooth palm shaft of a single roller cone drill bit to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6 This utility model discloses a welding fixture for applying a wear-resistant layer to the palm shaft of a single roller cone drill bit. It includes a device body for fixing the palm shaft of the drill bit. Specifically, the palm shaft of the drill bit includes a palm portion 40 and a shaft portion 50 integrally formed on the palm portion 40. The palm portion 40 is detachably connected to the device body.

[0020] In this embodiment, a horizontal rotation component 20 is provided at the upper end of the main body of the device. The horizontal rotation component 20 has a fixing component 60 for fixing the palm part 40, and the axis of the shaft part 50 is coaxially arranged with the rotation center of the horizontal rotation component 20, so that the horizontal rotation component 20 can drive the shaft part 50 to rotate horizontally around its own axis. With the setting of the horizontal rotation component 20, during the welding process, the drill bit palm shaft can be rotated in the horizontal direction by rotating the horizontal rotation component 20. When the drill bit palm shaft rotates, the position of the side of the shaft part 50 facing the processing personnel can be adjusted. In this way, when the processing personnel are performing welding, they only need to hold the welding tool on one side of the main body of the device, align the welding head with the part to be welded on the side of the shaft part 50, and adjust the welding position of the shaft part 50 by the horizontal rotation component 20 during the welding process. The processing personnel do not need to move the position themselves, which is convenient for operation.

[0021] In this embodiment, the fixing component 60 includes:

[0022] The support base 61 is fixed to the surface of the horizontal rotating component 20.

[0023] Side positioning members 63 are provided on both sides of the end of the bearing base 61 away from the rotation center of the horizontal rotating assembly 20. When the palm part 40 is placed on the bearing base 61, it is used to limit the two sides of the palm part 40 to prevent it from moving left and right in the horizontal direction.

[0024] An end positioning member 62 is provided on the surface of the bearing base 60 and at one end away from the rotation center of the horizontal rotating assembly 20. It is used to limit the end of the palm part 40 and prevent it from moving back and forth in the horizontal direction.

[0025] The annular fixing member 65 is fixed to one end of the bearing base 61 near the rotation center of the horizontal rotating component 20, and its upper end is inclined in the direction of the side positioning member 63 and the end positioning member 62. The palm part 40 has a structure similar to a cuboid. When in use, the palm part 40 is inserted into the annular fixing member 65, and the bottom sides of the palm part 40 contact the inner walls of the annular fixing member 62, which plays a role in limiting and supporting.

[0026] The fastening bolt 64 is threaded to the upper end of the annular fixing member 65, and its lower end is in close contact with the surface of the palm part 40 to achieve a stable fixation of the palm part 40, ensuring that the shaft part 50 of the drill bit palm shaft will not wobble when the horizontal rotating assembly 20 rotates.

[0027] In use, insert the palm part 40 of the drill bit palm shaft through the annular fixing member 65, so that the two sides of the palm part 40 are limited by the side positioning member 63, and the tail end of the palm part 40 is limited by the end positioning member 62. Then, rotate the fastening bolt 64 to make the bottom of the fastening bolt 64 in close contact with the upper surface of the palm part 40 to complete the limiting.

[0028] The side positioning member 63 and the end positioning member 62 can be taken from scrap steel blocks and fixed to the surface of the bearing base 61 by welding. The contact surface between the side positioning member 63 and the palm part 40 is preferably a planar structure.

[0029] The main body of the device includes a fixed base 11, and a vertical rotating component 30 is provided on the upper end of the fixed base 11. The vertical rotating component 30 is connected to the horizontal rotating component 20 for transmission and is used to drive the horizontal rotating component 20 to rotate in the vertical plane so that the shaft 50 can rotate in the vertical plane to adjust the tilt angle, further facilitating the operator to perform welding operations.

[0030] In some embodiments, the fixed base 11 includes two steel plates symmetrically arranged on both sides of the bottom of the horizontal rotating assembly 20, which are fixed together by steel bars 12. The vertical rotating assembly 30 includes a vertical rotating base 32 rotatably arranged on the upper part of the two steel plates and a first servo motor 31 fixed to the side of the steel plates for driving the vertical rotating base 32 to rotate. The horizontal rotating assembly 20 includes a horizontal rotating disk rotatably arranged on the surface of the vertical rotating base 32 and a second servo motor fixed to the vertical rotating base 32 for driving the horizontal rotating disk to rotate. The bearing base 61 of the fixed assembly 60 is welded and fixed to the horizontal rotating disk.

[0031] In use, the horizontal rotating component 20 drives the fixed component 60 to rotate, which in turn drives the drill bit palm shaft to rotate. The operator then uses a handheld welding device to weld a wear-resistant layer onto the side of the drill bit palm shaft 50. In addition, the vertical rotating component 30 allows the drill bit palm shaft to rotate in a vertical plane to adjust the tilt angle, making the welding operation more convenient.

[0032] Understandable, Figure 1 , Figure 3 The diagram shown is only a schematic diagram of the drill bit palm shaft fixation when welding areas a and b. When welding area c, it is only necessary to flip the palm 40 over and insert it into the annular fixing member 65 and fix it with the fastening bolt 64.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
