[0002] The clamping and positioning device of a machining center is used to fix the workpiece and determine its correct machining position in the machine tool. It ensures the stability and accurate positioning of the workpiece through clamping and positioning elements to meet machining requirements.

[0003] However, traditional machining center clamping and positioning devices mostly use a fixed structure, making it difficult to flexibly adapt to workpieces of different specifications. Even if some devices add simple adjustable clamping mechanisms, they still cannot effectively adjust the clamping position of the workpiece, making it difficult to ensure the stability and accuracy of clamping. In addition, traditional devices lack an effective chip collection structure, and the chips generated during processing will accumulate, which not only affects the cleanliness of the working environment, but also interferes with the processing, reducing processing efficiency and quality.

[0011] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0012] This invention, by setting up a clamping and positioning component, uses a motor to drive a gear to rotate, which in turn drives the racks on both sides to move in a straight line along the guide rail. This achieves precise horizontal movement and reliable clamping of the anti-slip clamping seats on both sides. The power transmission is direct and efficient, and it can quickly respond to operational needs, ensuring that workpieces of different specifications can be stably clamped on the workpiece placement seat. This provides a stable and accurate positioning basis for subsequent processing, effectively avoiding processing errors caused by unstable clamping, and improving the reliability and accuracy of processing.

[0013] This invention, by setting up a clamping seat height adjustment component, uses a motor two to drive a lead screw one to rotate, converting the rotational motion into linear motion of a drive block two along a guide rail two, thus realizing flexible adjustment of the anti-slip clamping seat height. It fully considers the needs of different workpiece specifications and sizes, and operators can easily adjust the height of the anti-slip clamping seat according to the actual situation to make it perfectly match the workpiece, ensuring the stability and accuracy of clamping.

[0014] This invention, through the combination of a debris collection component, a drop trough, and a debris guide plate, guides the debris generated during processing into a collection box, achieving efficient debris collection. Secondly, the collection box is slidably mounted on guide rail three, facilitating easy removal and installation by operators, making debris cleaning very convenient. Furthermore, the combination of motor three, lead screw two, mounting bracket, and cleaning brush enables rapid cleaning and removal of debris when cleaning the collection box, greatly improving cleaning efficiency, reducing manual cleaning workload, and maintaining a clean working environment.

The racks 24 mesh with the gear 23, converting the rotational motion of the gear 23 into linear motion, which drives the drive block 28 to move. A pair of guide rails 25 are installed in the mounting slot 21. The racks 24 on the same side are slidably mounted on the guide rails 25. The guide rails 25 provide a sliding track for the racks 24 to ensure the stability of the linear movement of the racks 24.

[0025] A cover plate 26 is provided on the top of the mounting slot 21. The cover plate 26 covers the mounting slot 21, protects the internal components, and provides the mounting position for the workpiece placement seat 27. The workpiece placement seat 27 is provided in the upper middle part of the cover plate 26. The workpiece placement seat 27 is used to place the workpiece to be processed. Both racks 24 are provided with drive blocks 28. Both drive blocks 28 are slidably mounted on the cover plate 26. The drive blocks 28 provide the mounting base for the clamping seat height adjustment assembly 3.

[0026] The clamping seat height adjustment assembly 3 includes a support frame 31 mounted on the drive block 28.

Each of the two drive blocks 28 is equipped with a fixing sleeve 32, inside which a lead screw 33 is installed. The fixing sleeve 32 provides support for the lead screw 33, ensuring its stability during rotation. A motor 34 is mounted on the top of each support frame 31 at a position corresponding to the fixing sleeve 32. One end of the lead screw 33 is connected to the transmission end of the motor 34. Next, motor 2 34 provides rotational power to lead screw 1 33, converting the rotational motion of lead screw 1 33 into linear motion of drive block 2 35. A pair of guide rails 2 36 are symmetrically arranged on the inner walls of both sides of support frame 31. Drive block 2 35 is slidably mounted on guide rails 2 36. Guide rails 2 36 provide sliding tracks for drive block 2 35, ensuring the stability of linear movement of drive block 2 35. Anti-slip clamping seats 37 are provided on one side of each of the two drive blocks 2 35. Anti-slip clamping seats 37 are used to clamp the workpiece to be processed and prevent the workpiece from moving during processing.

[0027] The debris collection assembly 4 includes a mounting slot 41 on one side of the workbench 1, in which a collection box 42 is installed. The collection box 42 collects debris generated during processing. A pair of guide rails 43 are provided at the bottom of the workbench 1, and the collection box 42 is slidably mounted on the guide rails 43. The guide rails 43 provide a sliding track for the collection box 42, facilitating its removal and insertion. A handle 46 is provided on the front of the collection box 42, which allows the operator to pull the collection box 42. A pair of drop grooves 44 are symmetrically provided on both sides of the workbench 1. The drop grooves 44 allow debris generated during processing to fall into the debris guide plate 45 and then into the collection box 42. The workbench 1 is equipped with debris guide plates 45 at an angle corresponding to the drop grooves 44. The tails of the two debris guide plates 45 are located directly above the collection box 42, guiding the debris into the collection box 42 to ensure accurate debris collection.

[0028] A pair of support seats 47 are provided on one inner wall of the collection box 42, and a lead screw 48 is provided between the two support seats 47. The support seats 47 provide support for the lead screw 48 to ensure the stability of the lead screw 48 during rotation. A motor 49 is provided on one inner wall of the collection box 42. The transmission end of the motor 49 is connected to one end of the lead screw 48, and the motor 49 provides rotational power to the lead screw 48, converting the rotational motion of the lead screw 48 into the linear motion of the mounting frame 410. The mounting frame 410 is spirally sleeved on the outside of the lead screw 48. The mounting frame 410 is a cleaning brush. 411 provides the installation base. A guide rail 412 is provided on the inner wall of the collection box 42 away from the lead screw 48. The mounting frame 410 is slidably mounted on the guide rail 412. The guide rail 412 provides a sliding track for the mounting frame 410 to ensure the stability of the linear movement of the mounting frame 410. A cleaning brush 411 is provided at the bottom of the mounting frame 410. The cleaning brush 411 cleans the debris in the collection box 42 to facilitate the discharge of debris. A discharge plate 413 is slidably mounted on the side of the collection box 42 away from the handle 46. The discharge plate 413 opens when cleaning debris to facilitate the discharge of debris.

[0029] In use, the operator first places the workpiece to be processed on the workpiece placement seat 27. Then, according to the specifications and dimensions of the workpiece, the operator can activate the clamping seat height adjustment component 3. The motor 2 34 drives the lead screw 1 33 to rotate, converting the rotational motion of the lead screw 1 33 into the linear motion of the drive block 2 35. This causes the drive block 2 35 and the anti-slip clamping seat 37 installed on one side to rise and fall along the guide rail 2 36. After the anti-slip clamping seat 37 is adjusted to the appropriate position, the operator can then activate the motor 1 22. The motor 1 22 drives the gear 23 to rotate. The gear 23 transmits power to the racks 24 on both sides through meshing, causing the racks 24 on both sides to move along the guide rail 1 25. When the racks 24 move, they will drive the drive block 1 28 and the clamping seat height adjustment component 3 installed on it to move together, thereby... The anti-slip clamping seats 37 on both sides are brought closer together to clamp the workpiece to be processed. During the processing, the generated debris will fall into the collection box 42 through the drop groove 44 and the debris guide plate 45. After processing, the operator can first pull the handle 46 to pull out the collection box 42, then pull out the unloading plate 413, and start the motor 3 49. The motor 3 49 drives the lead screw 2 48 to rotate, converting the rotational motion of the lead screw 2 48 into the linear motion of the mounting frame 410, so that the mounting frame 410 and the cleaning brush 411 installed at its bottom move along the guide rail 412, thereby cleaning and discharging the debris in the collection box 42. After cleaning, the unloading plate 413 can be inserted back into its original position, and then the collection box 42 can be aligned with the mounting groove 2 41 and reinstalled into the worktable 1 along the guide rail 3 43.
