Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a furniture sheet metal cutting and positioning fixture. Background Technology

[0002] Furniture board cutting and positioning fixtures are tools used in furniture production to improve cutting accuracy and efficiency. They are typically used to fix boards on cutting equipment to ensure the accuracy of the cutting line. Boards are often large and irregular, and manual operation or reliance solely on machines can easily lead to deviations, especially in mass production. Positioning fixtures help keep boards in the correct position, thus ensuring that each board is cut to the set dimensions. Existing furniture board cutting and positioning fixtures can horizontally position and clamp boards, but over-clamping thin boards or boards with special shapes can cause deformation and displacement. Therefore, furniture board cutting and positioning fixtures are needed.

[0003] Existing furniture board cutting and positioning fixtures fix the board by placing it between the fixtures and pressing down on the clamping blocks, which can lead to over-clamping, causing the board to deform and shift. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a furniture board cutting and positioning fixture, which aims to improve the problem of board deformation and displacement caused by excessive clamping force of the fixture.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a furniture board cutting and positioning fixture, comprising a base plate, a baffle fixedly connected to the upper surface of the base plate, a fixing plate fixedly connected to the upper surface of the base plate, a first limiting hole opened inside the fixing plate, a limiting block slidably connected inside the fixing plate, the outer wall of the limiting block slidably connected to the inside of the first limiting hole, a push plate fixedly connected to the outer wall of the limiting block, a plurality of first fixing posts fixedly connected inside the push plate, a first connecting rod rotatably connected to the outer wall of each of the plurality of first fixing posts, a connecting post rotatably connected inside the first connecting rod, a clamping block fixedly connected to the outer wall of the connecting post, a second connecting rod rotatably connected to the outer wall of the connecting post, a second fixing post rotatably connected inside the second connecting rod, the outer wall of the second fixing post fixedly connected to the inside of the push plate, and a driving assembly fixedly connected to the upper surface of the fixing plate.

[0006] Preferably, the driving component includes a fixing block, the lower surface of which is fixedly connected to the upper surface of a fixing plate, and a threaded rod is threadedly connected to the inside of the fixing plate, one end of which is rotatably connected to the inside of a push plate.

[0007] Preferably, a first track is fixedly connected to the upper surface of the base plate, and a first sliding block is slidably connected to the outer wall of the first track.

[0008] Preferably, a second track is fixedly connected to the upper surface of the first sliding block, and a second sliding block is slidably connected to the outer wall of the second track.

[0009] Preferably, the second sliding block has a second limiting hole inside, and a third sliding block is slidably connected to the outer wall of the second sliding block.

[0010] Preferably, the outer wall of the third sliding block is slidably connected to the inside of the second limiting hole.

[0011] Preferably, a motor is fixedly connected to the outer wall of the third sliding block, and a rotating column is fixedly provided at the output end of the motor.

[0012] Preferably, a blade is fixedly connected to the outer wall of the rotating column.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the push plate is moved by rotating the threaded rod inside the fixed block. The push plate drives the first connecting rod through the first fixed column inside.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figures 1-3 An embodiment of this utility model provides a furniture board cutting and positioning fixture, including a base plate 1, a baffle 2 fixedly connected to the upper surface of the base plate 1, a fixing plate 3 fixedly connected to the upper surface of the base plate 1, a first limiting hole 4 opened inside the fixing plate 3, a limiting block 5 slidably connected inside the fixing plate 3, the outer wall of the limiting block 5 slidably connected to the inside of the first limiting hole 4, a push plate 6 fixedly connected to the outer wall of the limiting block 5, a plurality of first fixing posts 7 fixedly connected inside the push plate 6, a first connecting rod 8 rotatably connected to the outer wall of each of the plurality of first fixing posts 7, a connecting post 9 rotatably connected to the inside of the first connecting rod 8, a clamping block 10 fixedly connected to the outer wall of the connecting post 9, a second connecting rod 11 rotatably connected to the outer wall of the connecting post 9, a second fixing post 12 rotatably connected to the inside of the second connecting rod 11, the outer wall of the second fixing post 12 fixedly connected to the inside of the push plate 6, and a driving assembly fixedly connected to the upper surface of the fixing plate 3.

[0024] Specifically, the base plate 1 fixes the baffle 2 and the fixing plate 3. The push plate 6 slides through the limiting block 5 at the first limiting hole 4. The first limiting hole 4 restricts the sliding of the push plate 6 through the limiting block 5 to prevent displacement during operation. The push plate 6 fixes multiple first fixing posts 7. The first connecting rod 8 and the second connecting rod 11 fix the clamping block 10 through the connecting post 9. The second fixing post 12 is fixed inside the push plate 6. The first connecting rod 8 rotates around the second fixing post 12 to fix the plate placed between the baffle 2 and the clamping block 10.

[0025] Reference Figure 3The drive assembly includes a fixed block 13, the lower surface of which is fixedly connected to the upper surface of the fixed plate 3, and a threaded rod 14 is threadedly connected inside the fixed plate 3, with one end of the threaded rod 14 rotatably connected inside the push plate 6.

[0026] Specifically, the fixing plate 3 fixes the fixing block 13, and the threaded rod 14 can rotate inside the fixing block 13 to drive the push plate 6 to slide.

[0027] Reference Figure 4 The upper surface of the base plate 1 is fixedly connected to the first track 15, and the outer wall of the first track 15 is slidably connected to the first sliding block 16;

[0028] Specifically, the base plate 1 fixes the first track 15, and the first sliding block 16 slides on the outer wall of the first track 15.

[0029] Reference Figure 4 The upper surface of the first sliding block 16 is fixedly connected to the second track 17, and the outer wall of the second track 17 is slidably connected to the second sliding block 18.

[0030] Specifically, the first sliding block 16 fixes the second track 17, and the sliding of the first sliding block 16 causes the second track 17 to slide simultaneously, while the second sliding block 18 slides on the second track 17.

[0031] Reference Figure 4 The second sliding block 18 has a second limiting hole 19 inside, and a third sliding block 20 is slidably connected to the outer wall of the second sliding block 18.

[0032] Specifically, the second limiting hole 19 is inside the second sliding block 18, and the third sliding block 20 slides on the outer wall of the second sliding block 18.

[0033] Reference Figure 4 The outer wall of the third sliding block 20 is slidably connected to the inside of the second limiting hole 19;

[0034] Specifically, the second limiting hole 19 restricts the sliding of the third sliding block 20 to prevent displacement.

[0035] Reference Figure 4 A motor 22 is fixedly connected to the outer wall of the third sliding block 20, and a rotating column 21 is fixedly installed at the output end of the motor 22.

[0036] Specifically, the third sliding block 20 fixes the motor 22, and starting the motor 22 drives the rotating column 21 to rotate.

[0037] Reference Figure 4 A blade 23 is fixedly connected to the outer wall of the rotating column 21;

[0038] Specifically, the rotation of the rotating column 21 drives the blade 23 to rotate.

[0039] Working principle: When the device is needed, the sheet material is first placed on the base plate 1 close to the baffle 2. By rotating the threaded rod 14 inside the fixed block 13, the push plate 6 is moved. The movement of the push plate 6 causes the limiting block 5 to slide inside the first limiting hole 4 in the fixed plate 3. The movement of the push plate 6 drives the first connecting rod 8 to move through the first fixed post 7. The first connecting rod 8 drives the clamping block 10 to slide on the upper surface of the base plate 1 through the connecting post 9. The push plate 6 drives the second connecting rod 11 to move through the second fixed post 12. The first connecting rod 8 and the second connecting rod 11 simultaneously drive the clamping block 10 to slide towards the baffle 2 through the connecting post 9, thus clamping and fixing the sheet material at multiple points, thereby achieving a uniform distribution of clamping force. This provides a more stable clamping effect for thin sheets or sheets with special shapes. After determining the cutting position of the sheet material, the third sliding block 20 is slid upward first. The blade 23 slides inside the second limiting hole 19 of the second sliding block 18, moving away from the base plate 1 for easy movement. It slides through the second track 17 fixed on the first track 15 by the first sliding block 16. The first track 15 is fixed to the upper surface of the base plate 1. After sliding to the appropriate position, the second sliding block 18 slides to the outer wall of the second track 17 to the position to be cut. The third sliding block 20 slides down, allowing the rotating column 21 to drive the blade 23 to fit against the plate to be cut. The motor 22 is started, and the rotating column 21 drives the blade 23 to rotate for cutting. This achieves the effect of multi-position cutting without removing the plate. This device can not only clamp and fix the plate at multiple points to achieve uniform distribution of clamping force, but also provide a more stable clamping effect for thin plates or plates with special shapes. It can also achieve the effect of multi-position cutting without removing the plate.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
