Description

Technical Field

[0001] This patent relates to the field of machining technology, specifically a workpiece clamping device that can collect debris. Background Technology

[0002] In the process of workpiece processing, the workpiece clamping device is an indispensable piece of equipment. Its main function is to firmly fix the workpiece to be processed to ensure processing accuracy and safety. However, most existing workpiece clamping devices only have clamping function. During workpiece processing, a large amount of debris is generated. This debris not only scatters on the worktable, affecting the cleanliness of the working environment, but may also enter the processing equipment, causing equipment failure and reducing the service life of the equipment.

[0003] In a gear processing clamping device that facilitates the handling of chips, as proposed in publication number CN221389222U, a collection basket is set directly below its clamping plate and locking assembly. The chips generated during processing can fall into the collection basket in a unified manner. Subsequently, only the chips in the collection basket need to be processed, thus saving more time and effort in the process of chip processing.

[0004] However, during the machining process, the chips will splash under the action of the cutting tool and will not fall directly downwards. As a result, the collection basket in the above document cannot effectively collect the chips, and some chips will still remain on its clamping device. Utility Model Content

Detailed Implementation

[0020] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Please see Figure 1-3 This utility model provides a technical solution:

[0022] In this technical solution, a workpiece clamping device that can collect debris includes a mounting plate 1 and a clamping frame 2. The clamping frame 2 is installed on both the left and right sides of the mounting plate 1. The clamping frame 2 can clamp the external workpiece to be processed. A material drop groove 3 is opened in the middle of the mounting plate 1. A dust collection mechanism 4 is installed in the material drop groove 3. The dust collection mechanism 4 can attract the debris generated during workpiece processing.

[0023] By setting clamping frames 2 on both sides of the mounting plate 1, the workpiece can be stably clamped from both sides, ensuring that the workpiece remains fixed during processing and avoiding the impact of shaking on processing accuracy; the combined design of the material drop chute 3 and the dust collection mechanism 4 allows the debris generated during processing to be attracted in time, preventing debris from flying everywhere. This not only keeps the working environment clean, but also prevents debris from entering the processing equipment, reducing the risk of equipment failure, and improving the service life of the equipment and processing safety.

[0024] The dust collection mechanism 4 includes a mounting groove 41, an exhaust fan 42, a dust filter 43, and a chip removal groove 44. The mounting plate 1 has a mounting groove 41 on its lower wall, which is connected to the material discharge chute 3. An exhaust fan 42 is installed in the mounting groove 41 and is electrically connected to an external power source. The dust filter 43 is installed on the inner wall of the material discharge chute 3 and is cone-shaped. The inner side wall of the material discharge chute 43 has a chip removal groove 44 that penetrates the side wall of the mounting plate 1.

[0025] In this technical solution, the mounting slot 41 provides a stable installation space for the induced draft fan 42, ensuring that the induced draft fan 42 can be firmly installed and operate normally. After the induced draft fan 42 is powered on, it generates suction force to suck the debris generated by external processing into the discharge trough 3, thereby collecting the debris.

[0026] The conical dust screen 43 design can more effectively intercept debris and prevent it from entering the blower 42 and damaging the equipment. On the other hand, the conical structure makes it easy for debris to slide down into the chip discharge trough 44 under the action of gravity, improving chip discharge efficiency. The chip discharge trough 44 penetrates the side wall of the mounting plate 1, which facilitates the discharge of collected debris and makes it easier for subsequent centralized processing. If debris accumulates, a scraper with a rod can be inserted into the chip discharge trough 44 to discharge the debris in the discharge trough 3 through the chip discharge trough 44.

[0027] In some technical solutions, the clamping frame 2 includes a fixing plate 21, a threaded hole 22, a screw 23, a clamping plate 24, and a connecting groove 25. The fixing plate 21 is installed on the edge of the upper wall of the mounting plate 1. The side wall of the fixing plate 21 has a threaded hole 22, and the screw 23 is screwed into the threaded hole 22. The side wall of the clamping plate 24 has a connecting groove 25, and the end of the screw 23 is inserted into the connecting groove 25. The screw 23 can rotate within the connecting groove 25.

[0028] In this technical solution, by rotating the screw 23, the screw 23 can be moved axially using the threaded transmission principle between the threaded hole 22 and the screw 23. Since the end of the screw 23 is inserted into the connecting groove 25 of the clamping plate 24 and can rotate, the movement of the screw 23 will drive the clamping plate 24 to move closer to or away from the fixed plate 21, thereby realizing the clamping and loosening of workpieces of different sizes. This structure is easy to adjust, has strong applicability, and can meet the clamping needs of workpieces of various specifications.

[0029] In some technical solutions, the side wall of the fixing plate 21 is provided with a guide groove 5, and one end of the guide rod 6 is installed on the side wall of the clamping plate 24. The other end of the guide rod 6 is slidably installed in the guide groove 5.

[0030] In this technical solution, the coordinated use of guide groove 5 and guide rod 6 provides precise guidance for the movement of clamping plate 24. When rotating screw 23 drives clamping plate 24 to move, guide rod 6 slides in guide groove 5, restricting the direction of movement of clamping plate 24 and preventing clamping plate 24 from deviating or tilting during movement. This ensures that clamping plate 24 can clamp workpiece smoothly and accurately, further improving the stability and reliability of workpiece clamping, ensuring machining accuracy, and also preventing clamping plate 24 from rotating with screw 23.

[0031] In some technical solutions, a cover 7 is installed below the mounting groove 41, and one end of the air outlet pipe 8 is inserted into the side wall of the cover 7. The other end of the air outlet pipe 8 is installed above the clamping plate 24.

[0032] In this technical solution, the cover 7 is installed below the mounting groove 41, which protects the internal components such as the blower 42 and prevents external debris from entering and affecting the operation of the equipment. At the same time, the air outlet duct 8 is connected to the cover 7, which can guide the air drawn in by the blower 42 to the top of the clamping plate 24 for discharge. The discharged air can form an airflow, which can blow the residual debris on the surface of the workpiece towards the discharge chute 3 to keep the workpiece processing area clean. On the other hand, the airflow can play a certain cooling role, reducing the temperature of the workpiece and the tool during the processing, extending the tool life and improving the processing efficiency.

[0033] In some technical solutions, a pipe clamp 9 is installed on the upper wall of the clamping plate 24. The pipe clamp 9 is inclined downwards, and the air outlet pipe 8 can be inserted into the pipe clamp 9.

[0034] In this technical solution, the pipe clamp 9 is installed on the upper wall of the clamping plate 24 and is inclined downwards, which can firmly hold the air outlet pipe 8, ensuring that the air outlet pipe 8 will not shake or fall off during use, thus ensuring the stability of airflow delivery. The downward inclined design allows the airflow direction discharged from the air outlet pipe 8 to be better aligned with the workpiece surface, improving the airflow's ability to blow away debris from the workpiece surface. At the same time, it can also more effectively guide the airflow to the processing area, enhancing the cooling effect and further optimizing the overall performance of the device.

[0035] In some technical solutions, the lower wall of the mounting plate 1 is provided with a clearance groove 10, and locking bolts 11 are inserted at the four corners of the upper wall of the mounting plate 1. The mounting plate 1 can be fixed to the external worktable by the cooperation between the locking bolts 11 and the screw holes on the external worktable.

[0036] In this technical solution, the clearance slot 10 is created to make way for the air duct 8;

[0037] By installing locking bolts 11 at the four corners of the upper wall of the mounting plate 1 and engaging with the screw holes on the external workbench, the mounting plate 1 can be firmly fixed to the workbench, preventing the device from shifting due to vibration or other reasons during workpiece processing, and providing a reliable installation foundation for the entire workpiece clamping device.

[0038] Working principle: First, fix the mounting plate 1 to the external workbench with locking bolts 11 to ensure the stability of the device;

[0039] Then, when using the workpiece clamping device, first adjust the position of the clamping plate 24 by rotating the screw 23 according to the size of the workpiece to be processed, and use the guide rod 6 to slide in the guide groove 5 to make the clamping plate 24 move closer or further away from the fixed plate 21, thereby clamping the workpiece between the two clamping frames 2.

[0040] Next, when the workpiece is being processed, the blower 42 is powered on and starts to generate suction. The chips generated during processing enter the material drop trough 3 under the action of suction. The chips are intercepted by the dust net 43 and slide into the chip discharge trough 44 under the action of gravity and the scraper operated by the external operator. At the same time, the air drawn in by the blower 42 is filtered and discharged above the clamping plate 24 through the air outlet pipe 8. The airflow formed blows away the chips on the surface of the workpiece and cools the processing area.
