Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of furniture manufacturing technology, and more specifically, to a fastening clamp for carving furniture parts. Background Technology

[0002] Furniture components are the basic units that make up all kinds of furniture. They include structural components, functional components, and decorative components. They are characterized by modularity, clear division of functions, and diverse materials. They are widely used in the production and assembly of various types of furniture, such as residential furniture, office furniture, and commercial furniture.

[0003] Currently, operators frequently need to use fastening clamps when carving furniture parts. While existing fastening clamps have basic functions for fixing furniture parts, they still have shortcomings in adaptability and ease of operation. Due to the diverse shapes of furniture parts, it is necessary to frequently change the corresponding clamping blocks during carving operations. However, the clamping blocks of the current fastening clamp use a screw-locking structure, which requires the use of special tools to tighten them during disassembly. This not only prolongs the time spent changing the clamping blocks but also increases the cumbersomeness of tool carrying and operation procedures, affecting the efficiency of carving operations and causing inconvenience to operators. Therefore, it is necessary to improve them. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this disclosure provide a fastening clamp for carving furniture parts, which solves the technical problem of inconvenient replacement of clamping blocks in the prior art.

[0005] According to one aspect, at least one embodiment of this disclosure provides a fastening clamp for carving furniture parts, including a workbench, a rectangular plate fixedly connected to the left side of the top of the workbench, a hollow block movably connected to the upper right side of the rectangular plate, springs fixedly connected to the four corners of the left side of the inner surface of the hollow block, a circular plate fixedly connected to the right side of the springs, the outer surface of the circular plate movably connected to the interior of the hollow block, a connecting plate located inside the right side of the inner surface of the hollow block movably connected to the right side of the circular plate, a circular shaft fixedly connected to the right end of the connecting plate, the right end of the circular shaft passing through the hollow block and extending to the outside of the right side of the hollow block and fixedly connected to a clamping block.

[0006] As a preferred technical solution of this utility model, a servo motor is fixedly installed on the upper left side of the rectangular plate, and a rotating shaft located inside the rectangular plate is fixedly sleeved at the other end of the output shaft of the servo motor. The right end of the rotating shaft is fixedly connected to the left side of the hollow block, and the outer surface of the rotating shaft is movably connected to the interior of the rectangular plate.

[0007] As a preferred embodiment of this utility model, table legs are fixedly connected to the four corners of the bottom of the workbench, and the number of table legs is four, with the four table legs having the same size.

[0008] As a preferred embodiment of this utility model, a movable plate is movably connected to the right side of the top of the workbench, and an auxiliary block is movably installed on the upper left side of the movable plate.

[0009] As a preferred embodiment of this utility model, the left end of the auxiliary block is fixedly fitted with an anti-slip block, and the outer surface of the anti-slip block is rough.

[0010] As a preferred embodiment of this utility model, the right end of the auxiliary block is fixedly connected to a short shaft located inside the movable plate, and the outer surface of the short shaft is movably connected to the interior of the movable plate.

[0011] As a preferred embodiment of this utility model, a circular block is fixedly connected to the right side of the short shaft, and the outer surface of the circular block is movably connected to the interior of the movable plate.

[0012] As a preferred embodiment of this utility model, a drive motor is fixedly installed at the rear right side of the workbench. A rotating shaft is fixedly sleeved at the other end of the output shaft of the drive motor. A long rod is fixedly sleeved on the outer surface of the rotating shaft. A movable rod is hinged to the left end of the long rod. The left end of the movable rod is hinged to the lower right side of the movable plate.

[0013] As a preferred embodiment of this utility model, the bottom end of the movable plate is fixedly connected to a limiting block located inside the workbench, and the outer surface of the limiting block is movably connected to the interior of the workbench.

[0014] As a preferred embodiment of this utility model, a baffle located inside the workbench is fixedly connected above the left end of the limiting block, the left end of the baffle extends to the outside of the left end of the workbench, and the outer surface of the baffle is movably connected to the inside of the workbench.

[0015] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, by setting up a hollow block, a spring, and a circular plate, the operator holds the circular shaft and applies a pushing force to the left, driving the connecting plate to detach from the inside of the right side of the hollow block and continuously move to the left. At this time, the spring is compressed and stores energy. Then, the operator rotates the circular shaft ninety degrees, and drives the connecting plate to rotate synchronously through torque transmission. Finally, the circular shaft is pulled to the right, so that the connecting plate is completely detached from the hollow block. During this process, the elastic potential energy of the spring is gradually released and the elastic force is restored. This operation process realizes the quick and convenient replacement of the circular shaft, effectively improving the efficiency of subsequent engraving operations.

[0016] 2. In this disclosure, by setting up a short shaft, a drive motor, a rotating shaft, a long rod, and a movable rod, after the operator starts the drive motor, its output torque is transmitted to the long rod through the rotating shaft, driving the long rod to rotate synchronously. Then, through the movable rod, the movable plate, the limit block, and the baffle are pushed to the left smoothly, so that the auxiliary block can accurately abut against the right end of furniture parts of different lengths. Together with the left clamping block, a bidirectional stable fixation is formed. This structural design greatly expands the applicable range of the fastening clamp, reduces the time spent on clamp adjustment due to the difference in length of furniture parts, and provides convenience for the operator's actual operation.

[0026] like Figures 1-6As shown, a fastening clamp for carving furniture parts according to an embodiment of the present disclosure is illustrated, including a workbench 1. A rectangular plate 2 is fixedly connected to the left side of the top of the workbench 1. A hollow block 3 is movably connected to the upper right side of the rectangular plate 2. Springs 4 are fixedly connected to the four corners of the left side of the inner surface of the hollow block 3. A circular plate 5 is fixedly connected to the right side of the springs 4. The outer surface of the circular plate 5 is movably connected to the interior of the hollow block 3. A connecting plate 6 located inside the right side of the inner surface of the hollow block 3 is movably connected to the right side of the circular plate 5. A circular shaft 7 is fixedly connected to the right end of the connecting plate 6. The right end of the circular shaft 7 passes through the hollow block 3 and extends to the outside of the right side of the hollow block 3 and is fixedly connected to a clamping block 8.

[0027] The design of the four springs 4 can effectively reset the movement of the circular plate 5. When the right side of the circular plate 5 is located on the left side of the connecting plate 6, it will fix the connecting plate 6, the circular plate 5, the circular shaft 7 and the clamping block 8.

[0028] In some examples, a servo motor 9 is fixedly installed on the upper left side of the rectangular plate 2. The other end of the output shaft of the servo motor 9 is fixedly sleeved with a rotating shaft 10 located inside the rectangular plate 2. The right end of the rotating shaft 10 is fixedly connected to the left side of the hollow block 3, and the outer surface of the rotating shaft 10 is movably connected to the interior of the rectangular plate 2.

[0029] Since both the outer surface of the rotating shaft 10 and the interior of the rectangular plate 2 are smooth, the rotating shaft 10 can rotate more smoothly inside the rectangular plate 2.

[0030] In some examples, table legs 11 are fixedly connected to the four corners of the bottom of the workbench 1. There are four table legs 11, and the four table legs 11 are the same size.

[0031] The design of the four table legs 11 provides excellent support for the entire workbench 1.

[0032] In some examples, a movable plate 12 is movably connected to the right side of the top of the workbench 1, and an auxiliary block 13 is movably installed on the upper left side of the movable plate 12.

[0033] Due to the design of the auxiliary block 13, its left end can abut against the right end of the furniture component, thereby fixing the furniture component.

[0034] In some examples, the left end of the auxiliary block 13 is fixedly fitted with an anti-slip block 14, the outer surface of which is rough.

[0035] The rough outer surface of the anti-slip block 14 further enhances the fixation of furniture parts.

[0036] In some examples, the right end of the auxiliary block 13 is fixedly connected to a short shaft 15 located inside the movable plate 12, and the outer surface of the short shaft 15 is movably connected to the interior of the movable plate 12.

[0037] Since both the outer surface of the short shaft 15 and the interior of the movable plate 12 are smooth, the rotation of the short shaft 15 inside the movable plate 12 is smoother.

[0038] In some examples, a circular block 16 is fixedly connected to the right side of the short axis 15, and the outer surface of the circular block 16 is movably connected to the interior of the movable plate 12.

[0039] Due to the design of the circular block 16, it can effectively limit the short axis 15.

[0040] In some examples, a drive motor 17 is fixedly installed at the rear right side of the workbench 1. A rotating shaft 18 is fixedly sleeved at the other end of the output shaft of the drive motor 17. A long rod 19 is fixedly sleeved on the outer surface of the rotating shaft 18. A movable rod 20 is hinged to the left end of the long rod 19. The left end of the movable rod 20 is hinged to the lower right side of the movable plate 12.

[0041] Since the connection between the rotating shaft 18 and the long rod 19 is fixed, when the rotating shaft 18 rotates, it will drive the long rod 19 to rotate as well.

[0042] In some examples, the bottom end of the movable plate 12 is fixedly connected to a limiting block 21 located inside the workbench 1, and the outer surface of the limiting block 21 is movably connected to the interior of the workbench 1.

[0043] Due to the design of the limit block 21, the movement of the movable plate 12 can be well guided.

[0044] In some examples, a baffle 22 located inside the worktable 1 is fixedly connected above the left end of the limiting block 21. The left end of the baffle 22 extends to the outside of the left end of the worktable 1, and the outer surface of the baffle 22 is movably connected to the inside of the worktable 1.

[0045] Due to the design of the baffle 22, wood chips can be prevented from falling into the interior of the worktable 1 during subsequent carving operations, thereby hindering the overall movement of the movable plate 12.

[0046] Working principle and usage process of this utility model: According to the shape of the furniture parts, the operator selects the corresponding clamping block 8 for installation. The round shaft 7 is inserted into the hollow block 3 from the outside right side. During the insertion process, the round plate 5 is pressed against by the connecting plate 6 and moves to the left, so that the spring 4 is in a compressed state. Then, the round shaft 7 is rotated ninety degrees and then slightly pulled to the right, so that the connecting plate 6 is inserted into the slot on the right side of the inner surface of the hollow block 3. At this time, the spring 4 pushes the round plate 5 to return to the right under the elastic recovery action. The right side of the round plate 5 is tightly pressed against the left side of the connecting plate 6. Through the dual action of mechanical locking and spring 4 pre-tightening, the connecting plate 6, round shaft 7 and clamping block 8 are firmly fixed, ensuring that the clamping block 8 will not loosen in subsequent operations.

[0047] After the clamping block 8 is installed, the operator places the left end of the furniture component into the clamping slot of the clamping block 8, and then starts the drive motor 17. The drive motor 17 drives the rotating shaft 18 and the long rod 19 to rotate synchronously. The long rod 19 is transmitted through the movable rod 20, pushing the movable plate 12 to move to the left as a whole. The movable plate 12 drives the anti-sliding block 14 to move synchronously. The anti-sliding block 14 is in close contact with the right end of the furniture component and applies a clamping force. With the clamping action of the left clamping block 8, the furniture component is fixed in both directions, ensuring the stability of the component position during subsequent processing.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
