Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to an automated blade clamping system. Background Technology

[0002] In modern manufacturing, cutting tools are key components in various cutting and slicing processes, and their machining accuracy and efficiency directly affect the quality of the final product and production efficiency. The clamping process in cutting tool machining plays a crucial role, not only in determining whether the cutting tool can be accurately positioned to meet subsequent machining requirements, but also in significantly impacting the smoothness of the overall production process.

[0003] Currently, there are two main methods for clamping and machining cutting tools in the industry. One is manual clamping. In practice, this requires an operator to be present next to the machine. Once the machining task starts, the operator manually clamps the cutting tool onto a specialized tool holder and then manually tightens it to ensure it doesn't shift during machining. However, this method has many drawbacks. High reliance on manual labor means continuous investment in labor costs, and the skill levels of operators vary. Even with standardized training, the level of care taken by different operators when clamping cutting tools is difficult to maintain consistently under long hours of repetitive work. This results in poor clamping consistency, ultimately leading to significant fluctuations in machining accuracy and difficulty in effectively controlling the defect rate.

[0004] Secondly, there is the automatic insert clamping technology, which is mostly found in high-end CNC machine tools. Leveraging advanced CNC systems and automated mechanical structures, these machine tools can generally achieve precise automated clamping and unloading of single inserts, greatly reducing human intervention and effectively improving clamping accuracy. However, its limitations are also quite obvious. Because the system design focuses on high-precision single-insert processing, the equipment's operating efficiency is significantly reduced when facing the demand for large-scale batch processing of inserts. Processing only a single insert at a time means frequent start-ups and shutdowns, program switching, and excessively long clamping and machining processes, failing to meet the urgent needs of modern industry for rapid, high-volume insert production.

[0005] In conclusion, existing cutting tool clamping methods struggle to balance precision, efficiency, and cost. There is an urgent need for an innovative clamping technology that can ensure high precision and consistency in cutting tool clamping while also adapting to the pace of mass production, thereby driving the further development of cutting tool manufacturing.

This further improves production efficiency and reduces production costs. Moreover, the various devices in this solution have relatively simple structures and easy-to-operate mechanisms, requiring no reliance on complex or high-cost high-end equipment, thus possessing strong practicality.

[0031] The following detailed explanation illustrates the specific implementation methods:

[0032] Example 1

[0033] The basic implementation examples are as follows: Figure 1 As shown: An automated blade clamping system includes a mounting platform 1, a blade gripping device 2, and a material tray 4.

[0034] The mounting platform 1 is equipped with a mounting frame 101; the blade gripping device 2 includes an auxiliary guide rail 201 mounted on the mounting frame 101, a robotic arm guide rail 203 mounted on the auxiliary guide rail 201, and a loading / unloading robotic arm 205 mounted on the robotic arm guide rail 203. Specifically, the loading / unloading robotic arm 205 is equipped with grippers 206 for clamping workpieces 9; in this embodiment, there are two grippers 206, which are driven by a servo motor inside the loading / unloading robotic arm 205 to clamp or release, and have a strong loading capacity. In specific applications, the loading / unloading robotic arm 205 can be an existing electric robotic arm.

[0035] The auxiliary guide rail 201 is arranged along the X-axis; the robot arm guide rail 203 is arranged along the Z-axis; the robot arm guide rail 203 and the auxiliary guide rail 201 are slidably connected by a slider, and the loading / unloading robot arm 205 is slidably connected to the robot arm guide rail 203 by a slider; the auxiliary guide rail 201 is provided with a first drive mechanism 202 for driving the robot arm guide rail 203 to move; the robot arm guide rail 203 is provided with a second drive mechanism 204 for driving the loading / unloading robot arm 205 to move.

[0036] The mounting platform 1 is provided with a material tray guide rail 3; the material tray 4 is slidably connected to the material tray guide rail 3; the material tray guide rail 3 is arranged along the Y-axis; the material tray guide rail 3 is provided with a third driving mechanism for driving the material tray 4 to move. The material tray 4 includes an upper material tray 401 and a lower material tray 402; both the upper material tray 401 and the lower material tray 402 are provided with storage compartments for accommodating workpieces 9.

[0037] The first drive mechanism 202, the second drive mechanism 204, and the third drive mechanism all include a servo motor and a lead screw, and the drive method is lead screw transmission. In specific applications, existing servo motor and lead screw devices can be used; the output shaft of the servo motor is rigidly connected to one end of the lead screw through a coupling to ensure that the center lines of the two are coincident, so as to achieve precise power transmission. A nut that matches the lead screw is installed on the slider. When the servo motor drives the lead screw to rotate, the nut will move linearly on the lead screw, thereby driving the slider to move on the guide rail.

[0038] Driven by the first drive mechanism 202, the second drive mechanism 204 and the third drive mechanism, the loading and unloading robot 205 can move in the XZ plane, and the material tray 4 can move in the Y axis. With the cooperation of the two, the loading and unloading robot 205 can accurately pick up the workpiece 9 from the loading tray 401 and return the workpiece 9 to the unloading tray 402.

[0039] This embodiment provides an automated blade clamping system. The loading / unloading robot 205 has precise movement capabilities in the XZ plane, and the material tray 4 can also accurately move along the Y axis. The precise cooperation between the two enables the accurate clamping and placement of workpiece 9. Furthermore, compared to manual loading / unloading, the coordinated operation of the robot and the material tray 4 is faster and more stable, enabling the transfer of workpiece 9 in a short time, shortening the production cycle of a single product, and helping to improve the overall production line efficiency.

[0040] Example 2

[0041] like Figure 2 and Figure 3 As shown, an automated blade clamping system, based on Embodiment 1, further includes a pneumatic clamp 5; the pneumatic clamp 5 includes a VV-shaped positioning block 501 for supporting the workpiece 9; one end of the VV-shaped positioning block 501 is provided with an auxiliary positioning block 502; the other end of the VV-shaped positioning block 501 is provided with a clamping mechanism 503; the clamping mechanism 503 includes a cylinder 504, a cylinder telescopic rod 505, and a pressure plate 506 connected to the cylinder telescopic rod 505. Furthermore, in the clamping mechanism 503, the pressure plate 506 is positioned closer to the VV-shaped positioning block 501.

[0042] In this embodiment, the workpiece 9 to be processed is an approximately triangular blade blank. The VV-shaped positioning block 501 can match the shape of the workpiece 9; together with the auxiliary positioning block 502 and the pressure plate 506, the workpiece 9 can be fully positioned and clamped.

[0043] In practical applications, the pneumatic clamp 5 can be installed on the machining platform of the machine tool 10 (a grinding machine in this embodiment), and the workpiece 9 to be processed can be placed on the storage compartment of the loading tray 401. When loading is required, the loading / unloading robot 205 is controlled to move to the loading tray 401 and clamp the workpiece 9 to the pneumatic clamp 5. The loading / unloading robot 205 places the workpiece 9 onto the VV-shaped positioning block 501 of the pneumatic clamp 5. At this time, the cylinder extension rod 505 remains in the shortened state. Then, the cylinder 504 is controlled to extend the cylinder extension rod 505, and the pressure plate 506 then presses against the workpiece 9, realizing the positioning and clamping of the workpiece 9. Then, the machine tool 10 can be started to process the workpiece 9. After the workpiece 9 is processed, first control the cylinder 504 to shorten the cylinder extension rod 505 to release the clamping of the workpiece 9, then control the loading and unloading robot 205 to move to the pneumatic clamp 5 to clamp the workpiece 9 to the unloading tray 402, and then place the workpiece 9 into the storage compartment of the unloading tray 402.

[0044] This embodiment provides an automated cutting tool clamping system that enables automatic loading, unloading, and clamping of workpiece 9. The system boasts a high degree of automation, significantly improving workpiece 9 processing efficiency. The pneumatic clamp 5 utilizes a stable air pressure source, allowing for precise control of clamping force and ensuring stable clamping by adjusting the air pressure. Furthermore, the rapid inflation and deflation of gas enables clamping and releasing actions, resulting in fast response and significantly reducing workpiece 9 clamping auxiliary time. The clamp structure is relatively simple, with few parts, a low failure rate, and easy maintenance.

[0045] Example 3

[0046] An automated blade clamping system, based on Embodiment 1 or Embodiment 2, further includes a flipping device 6, such as... Figure 4 and Figure 5 As shown. The flipping device 6 includes a base 601 mounted on the mounting platform 1; a flipping mechanism 7 and a positioning mechanism 8 are respectively provided on two adjacent sides of the base 601.

[0047] like Figure 6 and Figure 7As shown, the flipping mechanism 7 includes a flipping chuck 702; the flipping chuck 702 is provided with grippers 703; the flipping chuck 702 is connected to a fourth drive mechanism 701; the fourth drive mechanism 701 includes a first drive motor for driving the flipping chuck 702 to rotate and a second drive motor for driving the grippers 703 to clamp or release. In this embodiment, both the first drive motor and the second drive motor can be existing servo motors.

[0048] The positioning mechanism 8 includes a positioning guide rail 801 mounted on a base 601 and a support seat 803 slidably connected to the positioning guide rail 801; the support seat 803 is used to support the workpiece 9; in this embodiment, the workpiece 9 to be processed is an approximately triangular blade blank. The positioning guide rail 801 is also provided with a fifth driving mechanism 802 for driving the support seat 803 to move. The support seat 803 is provided with a V-shaped groove 804 with openings at both ends.

[0049] The axis of the flip chuck 702 is at an angle of 28-32° to the horizontal plane; the central axis of the positioning guide rail 801 is at an angle of 58-62° to the horizontal plane. In this embodiment, the axis of the flip chuck 702 is at an angle of 30° to the horizontal plane, and the central axis of the positioning guide rail 801 is at an angle of 60° to the horizontal plane. This arrangement, combined with the V-shaped groove 804 on the support seat 803, ensures that when the workpiece 9 is placed in the V-shaped groove 804, one of its surfaces to be processed remains horizontal and upward, guaranteeing the stability of the workpiece 9 while facilitating the control of the flip angle by the flip chuck 702.

[0050] In specific applications, taking the blank of the inner thread comb cutter for oil pipes as an example, the processing requirement is that the teeth need to be machined on both adjacent sides of the workpiece 9. After the teeth on one side are machined, the position of the workpiece 9 needs to be adjusted (rotated 120 degrees) in order to process the other side.

[0051] After machining one tooth profile, when it is necessary to flip the workpiece 9, the pneumatic chuck 5 first releases the clamp on the workpiece 9, and then the blade gripper 2 removes the workpiece 9 from the pneumatic chuck 5 and transfers it to the V-shaped groove 804 of the support seat 803. The blade gripper 2 is removed, and the jaws 703 clamp the workpiece 9. The support seat 803 is then removed, i.e., the support seat 803 is controlled to move up and down on the positioning guide rail 801 until it no longer obstructs the movement of the flipping chuck 702. The flipping chuck 702 is then rotated 180°, so that the other surface of the workpiece 9 to be machined is horizontally facing upwards. The support seat 803 is then reset, i.e., the support seat 803 is controlled to move upwards on the positioning guide rail 801 until it fully supports the workpiece 9, completing the flipping of the workpiece 9. The blade gripper 2 then clamps the flipped workpiece 9 and moves it back into the pneumatic chuck 5 for the next stage of machining.

[0052] This embodiment provides an automated blade clamping system that can perform continuous processing of different blade surfaces in an integrated manner, thereby further improving production efficiency and reducing production costs.
