Description

Technical Field

[0001] This utility model relates to the field of furniture processing technology, specifically to a furniture frame cutting device. Background Technology

[0002] As people's demands for the aesthetics and safety of furniture increase, furniture frames often employ methods such as 45-degree beveling and jointing. However, furniture manufacturers mostly use manual cutting for frame corners. This method results in inconsistent processing accuracy, especially when processing V-shaped cross-section frame corners, leading to complex processing procedures, low processing efficiency, and a low frame assembly yield, failing to meet the demands of high-quality furniture production. To address these issues, a furniture frame cutting device is proposed to solve these problems. Utility Model Content

[0005] The surface of the cutting table is symmetrically provided with fixing components, and the surface of the cutting table is symmetrically provided with guide rail grooves. The fixing components include a limiting frame that is slidably connected to the surface of the guide rail groove. The fixing components limit and fix the item to be cut.

[0006] Preferably, the fixing assembly further includes a mounting bracket fixedly installed at the center positions of both sides of the top of the cutting table, wherein a threaded block is slidably connected inside the mounting bracket, and a lead screw is installed on the radial inner wall of the threaded block through internal and external thread engagement.

[0007] Preferably, a first connecting frame is fixedly installed on the surface of the threaded block, and a second connecting frame is fixedly installed at the center of the top of the limiting frame. An adjusting rod is rotatably connected between the first connecting frame and the second connecting frame.

[0008] Preferably, one side of the lead screw is connected to a drive shaft extending into the cutting table, and a drive wheel is fixedly installed at the bottom end of the drive shaft, with a matching drive belt provided between the two drive wheels.

[0009] Preferably, a slider is slidably connected inside the guide rail groove, and shovel blocks are fixedly installed on both sides of the slider.

[0010] Preferably, the angle of the inclined surface of the shovel block is 30°.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] Driven by a servo motor, the threaded rod rotates, and the toothed plate interacts with the rotating threaded rod, causing the toothed plate to slide and engage with the gears, thereby adjusting the angle of the cutting mechanism. This results in more precise cutting and increased processing efficiency. Attached Figure Description

Detailed Implementation

[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] Example: Figures 1-4 As shown, this utility model provides a furniture frame cutting device, including a cutting table 1, a support 2 slidably connected to one side of the cutting table 1, a pre-embedded groove 3 inside the support 2, a sliding groove 4 penetrating the pre-embedded groove 3 on one side inside the support 2, a toothed plate 5 slidably connected inside the sliding groove 4, a threaded rod 6 installed on the radial inner wall of the toothed plate 5 through internal and external thread engagement, the threaded rod 6 rotates clockwise or counterclockwise under the drive of a first servo motor, the toothed plate 5 slides laterally inside the sliding groove 4 during the rotation of the threaded rod 6, a gear 7 adapted to the toothed plate 5 is rotatably connected inside the pre-embedded groove 3, the gear 7 rotates at a fixed point along with the turntable during the sliding of the toothed plate 5, thereby adjusting the cutting angle of the cutting mechanism, a turntable is installed on the surface of the gear 7, a guide rail frame 8 is fixedly installed on the surface of the turntable, and a cutting mechanism is slidably connected to one side of the guide rail frame 8;

[0021] The surface of the cutting table 1 is symmetrically provided with fixing components, and the surface of the cutting table 1 is symmetrically provided with guide rail grooves 13. The fixing components include a limiting frame 14 that is slidably connected to the surface of the guide rail groove 13. The fixing components limit and fix the item to be cut.

[0022] The fixing assembly also includes a mounting bracket 10 fixedly installed at the center of both sides of the top of the cutting table 1. A threaded block 11 is slidably connected inside the mounting bracket 10. A lead screw 12 is installed on the radial inner wall of the threaded block 11 through internal and external thread engagement. A first connecting bracket 16 is fixedly installed on the surface of the threaded block 11. A second connecting bracket 15 is fixedly installed at the center of the top of the limiting bracket 14.
