[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary tooling for sanding the surface of wooden furniture, including a workbench 1, a bracket 2 fixedly connected to the lower surface of the workbench 1, a support rod 3 fixedly connected to the upper surface of the workbench 1, a top plate 4 fixedly connected to the upper surface of the support rod 3, a clamping mechanism 5 provided on the lower surface of the top plate 4, the clamping mechanism 5 including a motor 501, a positive and negative lead screw 502, a T-shaped plate 503, a T-shaped groove 504, a clamping plate 505 and a rubber strip 506, an extension mechanism 6 provided on one side surface of the clamping plate 505, and a fixing mechanism 7 provided on the inner side surface of the extension mechanism 6;

[0021] The extension mechanism 6 includes a sliding groove 601, a limiting groove 602, a limiting block 603, a sliding block 604, an extension block 605, a limiting rod 606, and a limiting groove 607. A sliding groove 601 is formed on one side surface of the clamping plate 505. A limiting groove 602 is formed on the inner side surface of the sliding groove 601. A limiting block 603 is slidably connected to the inner side surface of the limiting groove 602. A sliding block 604 is fixedly connected to one side surface of the limiting block 603. An extension block 605 is fixedly connected to one side surface of the limiting block 603. A limiting rod 606 is fixedly connected to one side surface of the extension block 605. A limiting groove 607 is formed on the inner side surface of the clamping plate 505. The sliding groove... The arrangement of 601, 602, 603, 604, 605, 606, and 607 allows for the following: when the clamping range needs to be increased, the extension block 605 is pulled, the sliding block 604 slides within the sliding groove 601, the 603 slides within the 602, and the 606 slides within the 607. This ensures that the extension block 605 can move smoothly along the clamping plate 505, allowing for flexible adjustment of the clamping length. When dealing with large furniture, the length of the clamping mechanism 5 can be adjusted, enhancing the versatility and applicability of the tooling and enabling it to adapt to more wooden furniture of different sizes.

[0022] Furthermore, four sets of limiting blocks 603 are symmetrically arranged around the central axis of the sliding block 604. The sliding block 604 is slidably connected to the sliding groove 601. Through the setting of the limiting blocks 603, the four sets of limiting blocks 603 symmetrically arranged ensure the stability and balance of the sliding block 604 when it slides in the sliding groove 601 during use, and prevent the sliding block 604 from deviating or shaking.

[0023] Furthermore, a rubber strip 506 is provided on one side surface of the extension block 605, and two sets of extension mechanisms 6 are symmetrically arranged around the central axis of the clamping plate 505. The limiting rod 606 is slidably connected to the limiting groove 607. With the setting of the rubber strip 506, the rubber strip 506 increases the friction between the extension block 605 and the furniture surface during use, which can better fix the furniture when clamping it and prevent it from sliding.

[0024] Furthermore, a motor 501 is fixedly connected to one side surface of the top plate 4, and a positive and negative lead screw 502 is fixedly connected to one end surface of the motor 501. A T-shaped plate 503 is threadedly connected to the outer surface of the positive and negative lead screw 502. A T-shaped groove 504 is formed on the lower surface of the top plate 4. A clamping plate 505 is fixedly connected to one side surface of the T-shaped plate 503, and a rubber strip 506 is fixedly connected to one side surface of the clamping plate 505. The motor 501, positive and negative lead screw 502, T-shaped plate 503, and T-shaped groove 504 are connected to the top plate 4. 04. The clamping plate 505 and rubber strip 506 are designed so that when the motor 501 is started, it drives the positive and negative lead screws 502 to rotate. Since the positive and negative lead screws 502 are threadedly connected to the T-shaped plate 503, the T-shaped plate 503 will slide along the direction of the lead screw in the T-shaped groove 504, thereby driving the clamping plate 505 to move in opposite directions. The rubber strip 506 increases the friction when clamping the furniture, fixes the position of the furniture, makes the furniture more stable during the clamping process, and improves the safety and quality of the sanding operation.

[0025] Furthermore, the clamping plate 505 is provided with two sets on the outer surface of the positive and negative lead screws 502. The outer dimensions of the T-shaped plate 503 match the inner dimensions of the T-shaped groove 504. Through the arrangement of the T-shaped plate 503 and the T-shaped groove 504, the dimensions of the T-shaped plate 503 and the T-shaped groove 504 match during use, ensuring the smoothness and stability of the T-shaped plate 503 sliding in the T-shaped groove 504.

[0026] Furthermore, the fixing mechanism 7 includes a moving groove 701, a moving block 702, a locking block 703, a spring 704, a connecting rod 705, a pulling block 706, and a locking groove 707. The inner surface of the sliding block 604 has a moving groove 701. The moving block 702 is slidably connected to the inner surface of the moving groove 701. The locking block 703 is fixedly connected to one side surface of the moving block 702. The spring 704 is fixedly connected to the other side surface of the moving block 702. The connecting rod 705 is fixedly connected to the other side surface of the moving block 702. A pull block 706 is fixedly connected to one end of the connecting rod 705. A slot 707 is provided on the inner surface of the sliding groove 601. With the arrangement of the moving groove 701, the moving block 702, the slot 703, the spring 704, the connecting rod 705, the pull block 706, and the slot 707, when in use, pulling the pull block 706 will cause the moving block 702 to slide in the moving groove 701 through the connecting rod 705, compressing the spring 704 and causing the slot 703 to disengage from the slot 707. At this time, the extension block 605 can move freely. Once extended to the appropriate position, the pull block 706 is released, the spring 704 returns to its elastic deformation, and pushes the moving block 702, causing the locking block 703 to engage in the corresponding slot 707, thus fixing the position of the extended block 605. This allows for easy fixation of the extended block 605, ensuring that it will not slip during the grinding process, guaranteeing the stability of the clamping, and improving the reliability and practicality of the tooling.

[0027] Furthermore, multiple sets of slots 707 are equally spaced on the inner surface of the sliding groove 601. The slots 707 are slidably connected to the blocks 703. Through the arrangement of the slots 707 and the blocks 703, the multiple sets of equally spaced slots 707 provide multiple fixed position options for the blocks 703 during use. According to the actual size of the furniture, the extension block 605 can be adjusted to a suitable position so that the blocks 703 can be inserted into the corresponding slots 707.

[0028] Working principle: When the clamping range needs to be increased, the extension block 605 is pulled, the sliding block 604 slides in the sliding groove 601, the limiting block 603 slides in the limiting groove 602, and the limiting rod 606 slides in the limiting groove 607, ensuring that the extension block 605 can move smoothly along the direction of the clamping plate 505. The clamping length can be flexibly adjusted. When dealing with large furniture, the length of the clamping mechanism 5 can be adjusted, which enhances the versatility and applicability of the tooling, allowing the tooling to adapt to more wooden furniture of different sizes. Then, the pulling block 706 is pulled, which drives the moving block 702 to slide in the moving groove 701 through the connecting rod 705, compressing the spring 704 and causing the locking block 703 to disengage from the locking groove 707. At this time, the extension block 605 can move freely. Once extended to the appropriate position, the pull block 706 is released, the spring 704 returns to its elastic deformation, and pushes the moving block 702, causing the locking block 703 to engage in the corresponding slot 707, fixing the position of the extended block 605. This allows for easy fixation of the extended block 605, ensuring it will not slip during sanding, guaranteeing clamping stability, and improving the reliability and practicality of the tooling. When clamping wooden furniture, the motor 501 starts and drives the positive and negative lead screws 502 to rotate. Since the positive and negative lead screws 502 are threadedly connected to the T-shaped plate 503, the T-shaped plate 503 will slide along the direction of the lead screw in the T-shaped groove 504, thereby causing the clamping plate 505 to move in opposite directions. The rubber strip 506 increases friction when clamping furniture, fixing the furniture position and making the furniture more stable during clamping, thus improving the safety and quality of the sanding operation.
