Description

Technical Field

[0001] This utility model relates to the field of powder discharge trough processing technology, specifically a drill bit powder discharge trough processing device. Background Technology

[0002] In existing drill bit powder discharge groove processing technologies, manual methods or simple mechanical devices are typically used to fix the drill bit and perform the processing. These methods have the following problems:

[0003] 1. Unstable clamping: Traditional clamping devices often cannot be precisely adjusted according to the size of the drill bit, which causes the drill bit to wobble during processing, affecting the processing accuracy of the powder discharge trough and thus affecting product quality.

[0004] 2. Low processing efficiency: Traditional processing equipment requires frequent manual adjustment of the drill bit angle after processing a powder discharge trough. This not only increases the labor intensity of workers but also reduces production efficiency, making it difficult to meet the needs of mass production.

[0005] 3. Complex maintenance: Traditional processing equipment has a complex structure, making maintenance and repair difficult and increasing maintenance costs.

[0006] To address the aforementioned issues, this utility model provides a drill bit powder discharge groove processing device, which aims to overcome the shortcomings of existing technologies, improve processing accuracy and efficiency, and simplify equipment maintenance through an innovative clamping and driving mechanism. Utility Model Content

[0007] The purpose of this invention is to provide a drill bit powder discharge groove processing device to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a drill bit powder discharge groove processing device, comprising a CNC milling machine and a rotary table chuck mounted on the CNC milling machine worktable. The rotary table chuck includes a support platform detachably connected to the CNC milling machine worktable, a chuck laterally rotatably connected within the support platform, multiple jaws slidably mounted on one end of the chuck, a first driving member mounted on the support platform, and a second driving member mounted on the chuck. The first driving member is throttle-connected to the chuck to drive the chuck to rotate; the second driving member is throttle-connected to the multiple jaws to drive the multiple jaws to move closer or further apart.

[0009] Furthermore, the first driving component includes a first motor disposed on one side of the support platform and a first gear disposed on the output shaft of the first motor; one end of the chuck extends to the outside of the support platform and is connected to a second gear, and the first gear and the second gear mesh with each other.

[0010] Furthermore, the second driving component includes a second motor located on the other side of the support platform, a third gear located on the output shaft of the second motor, and a turntable rotatably connected to the clamping plate; a fourth gear is provided on one end of the turntable, the third gear and the fourth gear mesh with each other, and a radial spiral protrusion is provided on the other end of the turntable, and a groove adapted to the protrusion is provided on one side of the clamping claw, and the protrusion and the groove slide in cooperation.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model utilizes a second driving component (including a second motor, a third gear, a turntable, a fourth gear, a protrusion, and a groove) on the turntable chuck to drive multiple grippers to move synchronously closer or further away. This allows for precise adjustment based on the size of the drill bit, stably clamping different specifications of rock drilling bits and ensuring that the bit does not wobble during processing. This improves the processing accuracy of the powder discharge groove and guarantees product quality. Compared to traditional processing devices, the gripping method of this utility model is more flexible, avoiding processing errors caused by unstable clamping.

[0013] 2. The first driving component (including a first motor, a first gear, and a second gear) allows the chuck to rotate under the transmission of the first motor, the first gear, and the second gear. After each powder discharge trough is processed, the chuck can drive the drill bit to rotate at a certain angle. Combined with the operation of the CNC milling machine, frequent manual adjustment of the drill bit position is unnecessary, achieving highly efficient automated processing, improving production efficiency, and meeting the needs of mass production. Traditional equipment suffers from difficulty in adjusting processing angles, while this invention achieves automatic angle adjustment through simple motor-driven gear transmission, improving processing efficiency.

[0014] 3. The components of the rotary table chuck are rationally designed. For example, the support table can be detachably connected to the CNC milling machine worktable for easy installation and disassembly. The transmission structure between the chuck, grippers, and drive components is simple and easy to understand, facilitating maintenance and repair, and reducing equipment maintenance costs. Compared to the complex structure of traditional machining equipment, the structure of this utility model is simpler and easier to operate and maintain. Attached Figure Description

[0022] Please see Figures 1 to 5 A drilling bit powder discharge groove processing device is mainly used for processing drilling bit powder discharge grooves. It mainly consists of a CNC milling machine 1 and a rotary table chuck 2 mounted on the worktable of the CNC milling machine 1. The CNC milling machine 1 is specifically an XK6040 type milling machine, a common type of lifting table milling machine, mainly composed of a bed, spindle, and worktable. The worktable can move in six directions (up, down, left, right, and forward / backward) under the action of the lifting table, transverse slide, and longitudinal slide. The rotary table chuck 2 is mounted on the worktable to fix the drilling bit and drive its rotation. The drilling bit is then milled using a forming tool mounted on the spindle, thus completing the processing of the powder discharge groove.

[0023] Specifically,

[0024] The rotary table chuck 2 consists of a support platform 3, a chuck 4, multiple grippers 5, a first drive component, and a second drive component. The support platform 3 is detachably fixed to the worktable of the CNC milling machine 1 by bolts. The chuck 4 is laterally rotatably connected to the support platform 3 via bearings, and one end of the chuck 4 extends to the outside of the support platform 3 and is connected to a second gear 8; the other end of the chuck 4 also extends to the outside of the support platform 3, and multiple slide rails are equidistantly arranged along its circumference on the other end of the chuck 4. The multiple grippers 5 are slidably connected to the multiple slide rails respectively, and have grooves 14 at their bottom. The first drive component consists of a first motor 6 installed on one side of the support platform 3 and a first gear 7 located on the output shaft of the first motor 6; the first gear 7 meshes with the second gear 8, and when the first motor 6 drives the first gear 7 to rotate, it drives the chuck 4 to rotate synchronously. The second driving component consists of a second motor 9 mounted on the side wall of the clamp 4, a third gear 10 mounted on the output shaft of the second motor 9, and a turntable 11 rotatably connected to the clamp 4 via bearings; a fourth gear 12 is provided at one end of the turntable 11, and an opening is provided on one side of the clamp 4 to expose the teeth of the fourth gear 12 (e.g., ...). Figure 4 As shown), and the third gear 10 and the fourth gear 12 mesh with each other; the other end of the turntable 11 is provided with radial spiral protrusions 13 (as shown). Figure 5As shown, its structure is similar to that of a mosquito coil. The groove 14 at the bottom of the gripper 5 is adapted to the protrusion 13, and the protrusion 13 and the groove 14 slide together. When the second motor 9 drives the third gear 10 to rotate, it drives the turntable 11 with the fourth gear 12 to rotate. Through the cooperation of the groove 14 and the protrusion 13, the multiple grippers 5 move closer or further away at the same time to clamp the rod of the rock drill bit.

[0025] Both the first motor 6 and the second motor 9 mentioned above are stepper motors. When the second motor 9 is connected to the power supply, its wires need to be left with a certain distance so that the power will not be cut off due to insufficient distance when the second motor 9 rotates (the second motor 9 will not rotate more than 360 degrees).

[0026] Working process and principle of this utility model:

[0027] 1. Bit Fixing: Place the rock drill bit between multiple jaws 5 and start the second motor 9. The second motor 9 drives the third gear 10 on the output shaft to rotate. The third gear 10 meshes with the fourth gear 12 at one end of the turntable 11, thereby driving the turntable 11 to rotate. The radial spiral protrusion 13 at the other end of the turntable 11 slides in contact with the groove 14 at the bottom of the jaws 5. When the turntable 11 rotates, the protrusion 13 slides in the groove 14, thereby driving the multiple jaws 5 to move closer together and tightly fix and hold the rock drill bit.

[0028] 2. Machining Preparation: Install the forming tool onto the spindle of CNC milling machine 1. Write and debug the machining program using the control panel provided with CNC milling machine 1. Simultaneously, adjust the worktable so that the rock drill bit slightly contacts the forming tool, completing the centering and tool setting adjustment to ensure the accuracy of the machining position.

[0029] 3. Machining of powder discharge grooves: After debugging, the worktable returns to its original position, and the program starts machining. After machining one powder discharge groove, the first motor 6 is started. The first motor 6 drives the first gear 7 to rotate a certain number of revolutions. The first gear 7 meshes with the second gear 8 at one end of the chuck 4, thereby driving the chuck 4 to rotate a certain angle. The rock drill bit fixed on the chuck 4 also rotates at the corresponding angle. Each time the chuck 4 rotates once, the CNC milling machine 1 runs once, and this cycle continues until all powder discharge grooves of the rock drill bit are machined.
