Description

Technical Field

[0001] The invention relates to the technical field of drill bit welding, and in particular to a welding device for drill bit production. Background Art

[0002] Drill bits are basic tools widely used in the machining industry, and their quality and performance directly affect machining efficiency and product quality. In the drill bit production process, in order to ensure that the drill bit has good cutting ability and durability, a combination of carbide cutter heads and steel substrates is usually used to achieve a combination of high hardness of the cutting parts and high toughness of the substrate. Carbide materials have extremely high hardness and wear resistance, while steel substrates have good toughness and impact resistance. Therefore, firmly combining these two materials through welding technology is a key link in modern drill bit production. The quality of welding directly determines the strength, durability and service life of the drill bit. With the growth of precision machining needs, the industry's quality requirements for drill bits are also constantly improving.

[0003] Existing drill bit welding usually adopts manual welding or horizontal welding process. Although the operation is flexible and can adapt to the production needs of drill bits of different shapes and sizes, it is impossible to weld the base and multiple drill heads at the same time, so that after step-by-step welding, it is impossible to ensure that the axis of each drill head is consistent with the axis of the base, and it is impossible to ensure that the distance from each drill head to the axis of the base is consistent, which increases the possibility of breakage or performance degradation of the drill bit during use. In addition, the existing method of welding drill bits often causes uneven distribution of solder due to gravity, which in turn affects the uniformity and strength of welding.

[0004] Therefore, it is necessary to provide a welding device for drill bit production to solve the problem that the existing drill bit welding cannot ensure that the axis angle of each drill head is consistent with the axis angle of the base, and cannot ensure that the distance from each drill head to the axis of the base is consistent.

[0051] Reference Figures 1 to 8 The present invention provides a welding device for drill bit production, comprising:

[0052] A base 1, the upper end surface of which is mounted a fixing assembly 2, the fixing assembly 2 comprising a plurality of outward expansion plates 201, and a cylindrical base 110 is fixed to the outer sides of the plurality of outward expansion plates 201;

[0053] A welding assembly 3, wherein the welding assembly 3 is fixedly arranged on the upper end surface of the base 1, and the welding assembly 3 is provided with a plurality of high-frequency heating coils 301 uniformly surrounding the upper end surface of the substrate 110;

[0054] A clamping mechanism 4 is arranged above the base 110, and the clamping mechanism 4 includes a supporting tube 401 coaxially arranged with the base 110, an adjusting tube 402 is sleeved on the outer side of the supporting tube 401, and an adjusting shaft 403 is passed through the supporting tube 401, a first driving gear 404 is fixedly arranged at the bottom end of the adjusting shaft 403, the adjusting tube 402 is rotatably connected with a plurality of threaded rods 405 arranged at equal angles, a plurality of the threaded rods 405 are fixedly connected with a first driven gear 406 at one end facing the first driving gear, and a plurality of the threaded rods 405 are threadedly connected with a clamping assembly 407, and the clamping assembly 407 is provided with a clip 4071 for clamping the drill head 120, wherein a plurality of the first driven gears 406 are meshed with the first driving gear 404, and when the first driving gear 404 is rotated, a plurality of the drill heads 120 respectively move synchronously with the clamping assembly 407 and a plurality of the drill heads 120 are coaxial with the base 110.

[0055] In the above embodiment, the base 1 is the basic structure of the device, and a fixing assembly 2 is stably mounted on its upper end surface. The fixing assembly 2 includes a plurality of external expansion plates 201, and a cylindrical base 110 is fixed to the outer side of the plurality of external expansion plates 201. The base 110 is used to weld a plurality of drill heads 120. In the present application, the external expansion plates 201 are preferably provided with four, and the external expansion plates 201 are provided with arc-shaped supporting surfaces to adapt to drill bases 110 of different specifications. During the welding operation, the base 110 is stably supported by the external expansion plates 201, ensuring that no displacement or shaking occurs during the welding process, and providing structural guarantee for coaxial positioning.

[0056] The welding assembly 3 is fixedly connected to the upper end surface of the base 1 and is evenly arranged around the cylindrical substrate 110. The welding assembly 3 includes a plurality of high-frequency heating coils 301 evenly surrounding the upper end surface of the substrate 110. The specific number can be adjusted according to the actual needs of the drill bit. The high-frequency heating coils 301 generate a high-frequency electromagnetic field after being energized to evenly heat and weld the substrate 110 and the drill head 120. Due to the even distribution of the heating coils and the vertical placement of the substrate 110, the problem of uneven distribution of solder due to gravity in the traditional welding process can be avoided, ensuring the welding strength and uniformity. At the same time, by adopting the high-frequency induction heating method, the substrate 110 and the drill head 120 can be quickly heated to the required welding temperature, thereby improving the welding efficiency.

[0057] A clamping mechanism 4 is arranged above the base 110. The clamping mechanism 4 includes a support cylinder 401 coaxially arranged with the base 110. An adjusting cylinder 402 is sleeved on the outer side of the support cylinder 401. The adjusting cylinder 402 is used to support and control the positions of multiple drill heads 120. An adjusting shaft 403 is passed through the support cylinder 401. A first driving gear 404 is fixed at the bottom end of the adjusting shaft 403. When the first driving gear 404 rotates, the synchronous adjustment of multiple drill heads 120 is achieved through gear transmission. A plurality of threaded rods 405 arranged at equal angles are rotatably connected to the adjusting cylinder 402. One end of the threaded rods 405 facing the first driving gear 404 is fixedly connected to a first driven gear 406, and the first driven gear 406 is meshed with the first driving gear 404. A plurality of threaded rods 405 are threadedly connected to a clamping assembly 407. The clamping assembly 407 is provided with a clip 4071 for clamping the drill head 120. The plurality of drill bits 120 can be securely clamped by the clamping piece 4071 of the clamping assembly 407 .

[0058] During operation, when the adjustment shaft 403 drives the first driving gear 404 to rotate, the first driving gear 404 drives the multiple first driven gears 406 to rotate synchronously through meshing. The first driven gear 406 drives the threaded rod 405 to rotate synchronously in the adjustment cylinder 402, thereby driving the clip 4071 in the clamping assembly 407 to move closer to or away from the base 110, thereby adjusting the position of the drill head 120 to match the base 110. Since the multiple threaded rods 405 are evenly distributed at equal angles and move in coordination, the multiple drill heads 120 can move synchronously and be precisely fixed at a position coaxial with the base 110. At the same time, the distance between each drill head 120 and the axis of the base 110 can also be precisely controlled, ensuring the position consistency during the welding process.

[0059] In summary, the drill bit production welding device of the present invention realizes the coaxial positioning and equidistant control of each drill head 120 and the base 110 by setting the clamping mechanism 4 and the adjusting assembly, and the coordinated cooperation between the adjusting shaft 403, the first driving gear 404 and the plurality of threaded rods 405 enables the plurality of drill heads 120 to be synchronously adjusted and positioned under the action of the clamping assembly 407; when the first driving gear 404 rotates, each threaded rod 405 drives the clamping assembly 407 to evenly approach the base 110, and under the action of the coaxial support cylinder 401, ensures that each drill head 120 is aligned with the base 110. 10 always maintains a coaxial state; by clamping the drill head 120 with the evenly arranged clips 4071, the distance from each drill head 120 to the axis of the substrate 110 can be accurately controlled, overcoming the deviation problem caused by the step-by-step operation of the traditional welding method, thereby greatly improving the coaxial accuracy during the welding process; in addition, by the evenly distributed high-frequency heating coils 301 in the welding component 3 surrounding the vertically installed substrate 110, the substrate 110 and the drill head 120 are evenly heated and welded, avoiding the problem of uneven distribution of solder due to gravity in traditional welding, thereby ensuring the welding strength and weld uniformity.

[0061] A support ring 410 is also sleeved on the outside of the support cylinder 401, and an adjustment motor 411 is fixedly connected to the upper end surface of the support ring 410. A belt 412 is connected to the driving end of the adjustment motor 411. The belt 412 penetrates the support cylinder 401 and is connected to the adjustment shaft 403.

[0062] In the above embodiment, the guide rod 408 can ensure the linear movement of the clamping assembly 407 when adjusting the position of the drill head 120, avoiding twisting with the rotation of the threaded rod 405. The provision of the auxiliary ring 409 further enhances the stability between the guide rod 408 and the clamping assembly 407, making the entire clamping mechanism 4 more stable and reliable during operation. The rotational connection between the threaded rod 405 and the auxiliary ring 409 maintains the rotation stability of the threaded rod 405, so that the clamping assembly 407 can achieve precise fine adjustment through the rotation of the threaded rod 405, thereby achieving fine control of the position of the drill head 120.

[0063] The support ring 410 and the adjustment motor 411 are used in combination to provide a power source for adjusting the clamping mechanism 4. The adjustment motor 411 transmits power to the adjustment shaft 403 through the belt 412, thereby driving the movement of the entire clamping mechanism 4. The upper end surface of the support ring 410 is fixedly connected to the adjustment motor 411, ensuring the stability and transmission efficiency of the adjustment motor 411. The precise control of the adjustment motor 411 enables the clamping assembly 407 to be quickly and accurately positioned and adjusted as needed, greatly improving the automation and work efficiency of the welding device.

[0064] In summary, through the coordinated work of the clamping mechanism 4 and the adjustment assembly, the drill bit production welding device of the present invention can achieve high-precision coaxial positioning of the drill head 120 and the base 110, ensuring welding quality while improving production efficiency and operational convenience.

The upper end surface of the adjusting cylinder 402 is also provided with a rotating gear ring 416, and the rotating gear ring 416 is meshed with the rotating gear 415. When the rotating drive motor 414 drives the rotating gear 415, the rotating gear ring 416 drives the adjusting cylinder 402 to rotate, so that the clamping assembly 407 drives the drill head 120 to rotate around the support cylinder 401.

[0067] In the above embodiment, the inner side of the adjusting cylinder 402 is fixedly connected with an adjusting bearing 413, and the inner side of the adjusting bearing 413 is fixedly connected with the supporting cylinder 401. The adjusting cylinder 402 is rotatably connected with the supporting cylinder 401 through the adjusting bearing 413, which can realize the stable rotation of the adjusting cylinder 402 and ensure the synchronous adjustment function of the clamping assembly 407. The outer side of the supporting ring 410 is fixedly connected with a rotating drive motor 414 facing the adjusting cylinder 402, and the driving end of the rotating drive motor 414 is fixedly connected with a rotating gear 415. The upper end surface of the adjusting cylinder 402 is also provided with a rotating gear ring 416, which is meshed with the rotating gear 415 to ensure that the drive of the rotating drive motor 414 can be accurately transmitted to the adjusting cylinder 402 through the rotating gear 415, so that the adjusting cylinder 402 and the supporting cylinder 401 rotate together, thereby realizing the precise adjustment of the clamping assembly 407.

[0068] When the rotary drive motor 414 is started, the rotary gear 415 at the driving end drives the rotary gear ring 416 to rotate, thereby driving the adjustment cylinder 402 to rotate. The rotation of the adjustment cylinder 402 will drive the clamping assembly 407 to move around the support cylinder 401, thereby realizing the synchronous clamping and adjustment of the drill head 120, effectively enhancing the stability and accuracy of the device, ensuring the precise positioning and movement of the drill head 120, and further improving the coaxiality and consistency during the drill bit welding process.
