Description

Technical Field

[0001] This utility model belongs to the field of drill bit processing technology, and specifically relates to a rotary clamping mechanism for drill bit processing. Background Technology

[0002] Due to their unique structure and processing requirements, cylindrical drill bits often require multiple welding stations during the welding of alloy cutting tips using clamping and rotating mechanisms. In existing technologies, welding alloy cutting tips typically involves manual positioning and clamping, with multiple cutting tips on the drill bit welded sequentially using manual or semi-automatic methods. This processing method presents the following technical problems: Firstly, the positioning and clamping structures of the drill bits are mostly fixed or manually adjustable, making it difficult to meet the requirements of high-precision, multi-angle automated positioning, easily leading to unstable clamping or welding angle deviations; secondly, traditional structures generally lack synchronous rotation control functions in conjunction with electromagnetic induction heating equipment, failing to achieve accurate alignment of each welding station, severely restricting welding efficiency and processing consistency.

[0003] Furthermore, in actual operation, clamping mechanisms without automated angle recognition and control functions cannot accurately control the drill bit rotation angle by combining sensor feedback signals, requiring manual assistance for confirmation, which increases the processing difficulty, makes the labor intensity of operators greater, and causes significant fluctuations in welding quality. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a rotary clamping mechanism for drill bit processing. It can realize automatic clamping and precise positioning of cylindrical drill bits and complete multi-station welding in conjunction with an induction heating device, so as to solve the problems of low welding positioning accuracy, poor operation efficiency and low degree of automation in the existing processing methods.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A rotary clamping mechanism for drill bit processing includes a worktable and a cylindrical drill bit. A rotating disk is installed on the upper surface of the worktable near the left end, and a welding machine that can be adjusted left and right is installed on the upper surface of the worktable near the right end. Two clamping mechanisms for clamping the cylindrical drill bit are installed on the rotating disk. An electromagnetic induction coil that can be adjusted up and down is installed on the left side of the welding machine, and an electric lifting rod that drives the electromagnetic induction coil to rise and fall is fixed at the upper left corner of the welding machine.

[0007] A drive assembly for rotating the rotating disk is fixed on the lower side of the workbench, and an angle monitoring mechanism that works in conjunction with the rotating disk transmission is also installed on the lower side of the workbench. A control panel is fixed on the front side of the welding machine.

[0008] Furthermore, a rotating shaft is fixed at the center of the lower surface of the rotating disk, and a rotating gear is fixed at the lower end of the rotating shaft through the worktable.

[0009] Furthermore, the angle monitoring mechanism includes a U-shaped bracket fixed to the lower side of the worktable, an encoder fixed to the lower side of the bracket, and a stepped shaft connected to the encoder fixed to the lower end of the rotating shaft.

[0010] Furthermore, the drive assembly includes a mounting bracket fixed to the underside of the worktable and a motor fixed to the mounting bracket, with a drive gear meshing with the rotating gear fixed on the output shaft of the motor.

[0011] Furthermore, the clamping mechanism includes a support plate fixed on the rotating disk and a clamping block located inside the support plate. A guide rod that passes through the support plate is fixed on one side of the clamping block, and an electric telescopic rod that drives the clamping block to perform clamping action is fixed on one side of the support plate.

[0012] Furthermore, the welding machine has two slots on the lower side, one in the front and one in the back. A guide rail that mates with the slots is fixed on the worktable. A locking block is fixed on the right side of the welding machine at the position corresponding to the slot. A locking screw is threaded on the upper surface of the locking block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention, by setting a rotating disk equipped with a clamping mechanism, can stably clamp the cylindrical drill bit, avoiding the problem of drill bit displacement caused by manual fixing in the prior art, and improving the positioning accuracy of the workpiece during welding; by driving the clamping block with an electric telescopic rod to automatically clamp the drill bit, it overcomes the defects of low efficiency and poor clamping reliability of manual adjustment, and realizes fast and stable clamping control of the drill bit.

[0015] This invention achieves multi-position precise rotation of the cylindrical drill bit by setting a drive assembly consisting of a rotating shaft, rotating gear, drive gear and motor under the rotating disk, combined with an angle monitoring mechanism composed of an encoder. The rotation angle is monitored in real time by the encoder and transmitted to the control panel for automatic judgment and control, which solves the problems of manual rotation and alignment and low positioning accuracy in traditional processing, and effectively improves the automation level and consistency of welding operations.

[0016] This invention utilizes an electromagnetic induction coil controlled by an electric lifting rod, combined with a welding machine that can slide and adjust on a guide rail. This allows the induction coil to accurately align with the welding position of each alloy cutting head, automatically completing the upper and lower heating operations. This avoids the welding misalignment or unevenness problems caused by manual alignment or fixed heating in existing systems, achieving automation, precision, and consistency in welding operations, and improving welding quality and efficiency.

[0017] This invention uses a control panel to uniformly control the welding machine, rotating mechanism, electric telescopic rod, and angle monitoring mechanism, breaking the problem of independent and inaccurate coordination between welding and rotation control in existing systems. This allows the entire welding process to be completed automatically according to a set logical sequence, ensuring precise welding position and synchronized welding actions for each cutting head, further optimizing the stability and consistency of the processing.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1As shown, a rotary clamping mechanism for drill bit processing includes a worktable 1 and a cylindrical drill bit 4. A rotating disk 2 is mounted on the upper surface of the worktable 1 near the left end, and a welding machine 7 with adjustable left and right positions is mounted on the upper surface of the worktable 1 near the right end. Two clamping mechanisms 3 are mounted on the rotating disk 2 to clamp the cylindrical drill bit 4, enabling positioning and fixing of the cylindrical drill bit 4 during the welding process and preventing welding accuracy from being affected by positional deviation. An electromagnetic induction coil 5 with adjustable up and down positions is mounted on the left side of the welding machine 7. By controlling its heating position, the electromagnetic induction coil 5 can precisely act on the alloy cutting head area of ​​the cylindrical drill bit 4, improving welding uniformity. A driving electromagnetic coil is fixed at the upper left corner of the welding machine 7. The electric lifting rod 6, which raises and lowers the induction coil 5, achieves adaptive heating for different height positions by controlling the vertical displacement of the induction coil. A drive assembly 10, which drives the rotating disk 2, is fixed on the lower side of the worktable 1. It is used to cooperate with the motor to control the cylindrical drill bit 4 to rotate to a set angle to complete the multi-position welding operation. An angle monitoring mechanism 11, which is in transmission cooperation with the rotating disk 2, is also installed on the lower side of the worktable 1. The angle monitoring mechanism 11 achieves high-precision rotation positioning of the cylindrical drill bit 4 by detecting the rotation shaft angle in real time. A control panel 9 is fixed on the front side of the welding machine 7. The control panel 9 is used to centrally control the motor, lifting rod, encoder and other execution units to improve the overall automation level and processing consistency of the system.

[0027] like Figure 2 As shown, a rotating shaft 21 is fixed at the center of the lower surface of the rotating disk 2. The lower end of the rotating shaft 21 passes through the worktable 1 and is fixedly connected to a rotating gear 22. The rotating shaft 21 serves as the core component for the support and transmission of the rotating disk 2. Under the driving action of the drive assembly 10, it achieves stable rotation, ensuring that the cylindrical drill bit 4 completes multi-angle welding tasks in a rotating clamped state. The rotating gear 22 meshes with the drive gear 102 of the drive assembly 10 to form a stable power transmission path, providing continuous and controllable rotational power for the rotating disk 2.

[0028] like Figure 3 As shown, the angle monitoring mechanism 11 includes a U-shaped mounting bracket 111 fixed to the lower side of the workbench 1. The mounting bracket 111 has a stable structure and is used to provide the installation reference for the encoder 112, avoiding the impact of vibration on the monitoring accuracy during the welding process. The encoder 112 is fixed to the lower side of the mounting bracket 111. The encoder 112 is used to detect the rotation angle of the rotating shaft 21 in real time and transmit the angle signal to the control panel 9 as the basis for judging whether the motor stops. The lower end of the rotating shaft 21 is fixed with a stepped shaft connected to the encoder 112. The structural design of the stepped shaft facilitates matching with the measurement port of the encoder, ensuring accurate monitoring signals and timely response.

[0029] like Figure 4As shown, the drive assembly 10 includes a mounting bracket 103 fixed to the lower side of the worktable 1. The mounting bracket 103 is used to support the motor 101 and ensure the meshing stability of its output shaft with the rotating gear 22. The motor 101 is fixed on the mounting bracket 103. The motor 101 serves as a drive source to provide power to the entire rotating system. A drive gear 102 that meshes with the rotating gear 22 is fixed on its output shaft. The drive gear 102 transmits power through meshing with the rotating gear 22, enabling the rotating disk 2 and the cylindrical drill bit 4 to achieve precise angular rotational positioning.

[0030] like Figure 2 As shown, the clamping mechanism 3 includes a support plate 33 fixed on the rotating disk 2. The support plate 33 provides the mounting base for the clamping block 34 and rotates synchronously with the rotating disk 2. The clamping block 34 is installed on the inner side of the support plate 33. The clamping block 34 is used to axially clamp and fix the cylindrical drill bit 4 to prevent displacement during welding. A guide rod 31 that passes through the support plate 33 is fixed on one side of the clamping block 34. The guide rod 31 ensures that the movement path of the clamping block 34 is stable during clamping and releasing, avoiding displacement and jamming. An electric telescopic rod 32 that drives the clamping block 34 to perform clamping action is also fixed on one side of the support plate 33. The electric telescopic rod 32 drives the clamping block 34 to perform linear movement under the drive of the control signal, realizing the rapid clamping and release of the cylindrical drill bit 4, significantly improving the workpiece change efficiency and the degree of automation of the operation.

[0031] like Figure 5 As shown, the welding machine 7 has two slots 73 on its lower side, front and rear. The slots 73 cooperate with the guide rail 8 to realize the horizontal adjustment function of the welding machine 7, which facilitates the alignment operation of the electromagnetic induction coil 5 with different heights or different types of cylindrical drill bits 4. The worktable 1 is fixed with the guide rail 8 that cooperates with the slots 73. The guide rail 8 serves as a moving reference track to ensure the stability and accuracy of the welding machine 7 during movement. The right side of the welding machine 7 is fixed with a locking block 71 at the position corresponding to the slots 73. The locking block 71 is used to lock the position of the welding machine 7 after adjustment to prevent displacement interference during the welding process. The upper surface of the locking block 71 is threaded with a locking screw 72. The locking screw 72 is used to realize a firm connection between the locking block 71 and the welding machine 7, ensuring the stable operation of the welding machine 7 and further improving the welding accuracy and consistency.

[0032] The working principle of this utility model is as follows: When welding the alloy cutting head onto the cylindrical drill bit 4, the cylindrical drill bit 4 is placed on the rotating disk 2. At this time, the electric telescopic rods 32 on both sides simultaneously drive the clamping blocks 34 on both sides to move relative to each other to clamp and fix the cylindrical drill bit 4. Then, the welding machine 7 is moved so that the electromagnetic induction coil 5 is aligned with the upper edge of the cylindrical drill bit 4. At this time, the control motor 101 drives the rotating gear 22 to rotate the rotating disk 2 so that the position for embedding the alloy cutting head is aligned with the electromagnetic induction coil 5. At this time, the electric lifting rod 6 drives the electromagnetic induction coil 5 to descend and fit onto the position of the alloy cutting head for heating and welding. After the welding of one alloy cutting head is completed, the electromagnetic induction coil 5 is raised. At this time, the control panel 9 controls the motor 101 to drive the rotating disk 2 and the cylindrical drill bit 4 to rotate. When the encoder 112 detects that the rotating shaft 21 has rotated to the set angle, it transmits the signal to the control panel 9. At this time, the motor 101 stops moving. Then, the electromagnetic induction coil 5 descends to perform heating and welding, realizing the clamping and rotation control during the welding of the cylindrical drill bit 4, thereby completing the automated welding operation of the alloy cutting head on the cylindrical drill bit 4.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
