[0024] Example:

[0025] like Figure 1-4As shown, a workpiece cutting and waste collection device includes a frame 1 connected by rectangular tubes. A worktable 2 is located in the middle of the frame 1. The worktable 2 is equipped with a cutting unit, a clamping unit, and a resetting unit to cooperate in cutting the workpiece. Specifically, the cutting unit includes a servo motor 3, which outputs circular motion and is mounted on the worktable 2. The output shaft of the servo motor 3 is supported on the worktable 2 through a bearing seat 21 and a bearing. The output shaft is connected to a composite tool holder and a cutting blade 4, driving the cutting blade 4 to perform circular motion for cutting the workpiece. The clamping unit includes a servo cylinder 5, which outputs linear motion. The telescopic rod of the servo cylinder 5 is set downwards and connected to a multi-module clamping assembly. The multi-module clamping assembly can be adapted to fix workpieces of different specifications by changing parts, which can solve the problem of universality for multiple varieties and small batches. The servo cylinder 5 drives the multi-module clamping assembly to fix the workpiece and continues to move the workpiece downwards until it contacts the cutting blade 4 and is pierced by the cutting blade 4. At this time, the servo cylinder 5 stops working, and the servo motor 3 is started to drive the cutting blade 4 to perform circular cutting motion on the outside of the workpiece, completing the cutting of the workpiece. After the cutting is completed, when the servo cylinder 5 withdraws its clamping force on the workpiece, the reset unit drives the workpiece away from the working area of ​​the cutting blade 4, facilitating the next cutting. In this embodiment, two sets of cutting units, clamping units, and reset units are provided, which can complete the cutting of two workpieces simultaneously.

[0026] The clamping unit also includes two large positioning columns 10, which are arranged parallel to each other and installed on the worktable 2. A mounting plate 11 is provided between the two large positioning columns 10 for mounting the cylinder body of the servo cylinder 5. The mounting plate 11 has a through hole for the extension rod of the servo cylinder 5 to extend. The end of the extension rod is connected to a fixing plate 12 for mounting the multi-module clamping assembly. Both large positioning columns 10 are provided with sliding sleeves, and the fixing plate 12 is connected between the two sliding sleeves. When the servo cylinder 5 drives the extension rod to move, the cooperation between the sliding sleeves and the large positioning columns 10 ensures that the extension and retraction of the extension rod is in the direction perpendicular to the horizontal plane.

[0027] The multi-module fixture assembly includes an upper mounting base 6, a lower mounting base 7, and several sets of modular fixtures. Different modular fixtures can be used to accommodate different workpieces. They are manufactured according to the workpiece specifications. Each set of modular fixtures includes an upper quick-change clamping block 8 and a lower quick-change clamping block 9, each with a corresponding workpiece contour for clamping. The upper end of the upper quick-change clamping block 8 is detachably connected to the upper mounting base 6, and the lower end of the lower quick-change clamping block 9 is detachably connected to the lower mounting base 7. The only difference between the various sets of modular fixtures is their contour; the connection structure between the upper mounting base 6 and the lower mounting base 7 is identical, facilitating quick replacement to accommodate different workpieces.

[0028] The reset unit includes several springs 13, which are evenly distributed at the bottom of the lower mounting base 7. The lower mounting base 7 is connected to the worktable 2 through the springs 13. It also includes two small positioning pins 14, which are arranged parallel to each other on the worktable 2. The two ends of the lower mounting base 7 are provided with corresponding positioning holes. The two small positioning pins 14 pass through the two positioning holes respectively, ensuring that the movement of the lower mounting base 7 is also in the direction of the vertical and horizontal lines. The small positioning pins 14 are arranged parallel to the large positioning pins 10. When the servo cylinder 5 drives the module clamp to move down, it sequentially drives the upper quick-change clamping block 8 and the lower quick-change clamping block 9 to contact and clamp the workpiece. Then, it needs to move down quickly until the workpiece is pierced by the cutting blade 4. At this time, the springs 13 are in a compressed state. After the cutting is completed, the servo cylinder 5 drives the upper quick-change clamping block 8 to move up, and the lower quick-change clamping block 9 and the lower mounting base 7 are reset by the force of the springs 13.

[0029] The composite tool holder includes a vertical tool holder 15 and a horizontal tool holder 16. One end of the vertical tool holder 15 is perpendicularly connected to the end of the rotating shaft 22, and the other end of the vertical tool holder 15 is perpendicularly connected to the horizontal tool holder 16, which is located on the opposite side of the servo motor 3. The other end of the horizontal tool holder 16 is connected to the cutting blade 4, and the cutting edge of the cutting blade 4 is arranged parallel to the vertical tool holder 15. In the initial position, the cutting blade 4 faces directly upward.

[0030] It also includes a control cabinet 17, a start button, a stop button, and an emergency stop button. The control cabinet 17 is electrically connected to the servo motor 3 and the servo cylinder 5, respectively. By setting control logic, the corresponding functions of each button are realized. The start button, stop button, and emergency stop button are set outside the frame 1. A grating sensor 18 is also set on the frame 1, which is set on the four rectangular tubes of the frame 1. It detects the approach of a human body by transmitting and receiving signals to each other. At the same time, an alarm 19 is set to cooperate. When someone puts their hand into the work platform during the detection process, it transmits a signal to the control cabinet 17 to control the alarm light to start, providing safety protection for employees and improving the safety of equipment use.

[0031] A waste inlet is provided below the cutting blade 4 on the workbench 2, and a waste frame 20 is provided below the waste inlet. The waste material cut by the cutting blade 4 falls into the waste frame 20 through the waste inlet and is collected.

[0032] During operation, the workpiece is pre-loaded into the upper and lower quick-change clamps 9 in sequence, and the start button is pressed. First, the servo cylinder 5 drives the fixed plate 12, upper mounting base 6, upper quick-change clamp 8, lower quick-change clamp 9, lower mounting base 7, and workpiece to move downwards together, and the workpiece is pierced by the cutting blade 4. Then, the servo motor 3 starts to rotate 360 ​​degrees, the workpiece is cut off, and the cut waste falls through the waste outlet on the worktable 2 to the waste frame 20 at the bottom for collection. Then, the servo cylinder 5 returns to the starting position, the spring 13 resets, the workpiece is removed, and the next cutting continues.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the content of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
