Description

Technical Field

[0001] This utility model relates to the field of wood cutting technology, and in particular to a wood cutting force adjustment structure. Background Technology

[0002] Wood is processed using board cutting machines to cut wood for various applications. However, most board cutting machines tend to cause the wood to shift from its original position during the cutting process, which affects the cutting accuracy and thus the processing of the wood.

[0003] Utility model patent CN220661195U discloses a wood cutting force adjustment structure, including a fixed platform, a base plate on the upper surface of the fixed platform, a movable plate on the upper surface of the base plate, a clamping platform on the upper surface of the movable plate, a top plate above the fixed platform, connecting rods at the four corners of the lower surface of the top plate, an electric telescopic rod on the upper surface of the top plate, the telescopic arm of the electric telescopic rod passing through the top plate and having a cutting motor at its bottom, the output shaft of the cutting motor being coaxially connected to a cutting blade, and a first cutting blade being cut in the middle of the base plate. A trapezoidal groove is provided, in which a first screw is provided. A first trapezoidal block is provided at the bottom of the movable plate, and a first screw hole is provided on the first trapezoidal block. A second trapezoidal groove is provided on the upper surface of the movable plate, in which a second screw is provided. A second trapezoidal block is provided at the bottom of the clamping platform, and a second screw hole is provided on the second trapezoidal block. Several third screw holes are symmetrically provided on the clamping platform, and a third screw is provided in each of the third screw holes. A handle is provided at one end of the third screw, and a universal joint is provided at the other end of the third screw. A rubber sleeve is provided at the end of the universal joint.

[0004] In the above solution, the third screw can be manually rotated by turning the handle to achieve a close connection between the universal joint 621 and the outer wall of the wood. With the cooperation of the rubber sleeve, the damage to the wood is reduced. However, since each of the third screw holes is equipped with a third screw, multiple third screws need to be turned when rotating the third screw by turning the handle, which is inconvenient.

[0005] Therefore, we propose a wood cutting force adjustment structure to solve the above problems. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0036] Reference Figure 1-8A wood cutting force adjustment structure includes a clamping platform 1. For details of the clamping platform 1 and other unnumbered components, please refer to the patent with publication number CN220661195U. A trapezoidal block 101 is provided at the middle of the bottom of the clamping platform 1. Support sliders 102 are provided on both sides of the bottom of the clamping platform 1. The support sliders 102 can support the clamping platform 1 and assist its movement. Multiple sets of through holes 105 and displacement holes 106 are provided on both sides of the clamping platform 1. Two rows of force compression adjustment structures 2 are provided on the clamping platform 1. The force compression adjustment structure 2 includes a compression component 21, a limiting component 22, a transmission component 23, a transmission chain 24, and an adjustment component 25. A positioning and locking component 3 is provided between the two support sliders 102.

[0037] The extrusion member 21 includes an extrusion rod 211 located in the through hole 105. The extrusion rod 211 is a screw. The end of the extrusion rod 211 is connected to an elastic force-bearing extrusion head 213. The elastic force-bearing extrusion head 213 can be made of rubber to prevent extrusion damage to the wood.

[0038] The limiting member 22 includes a limiting rod 222 connected to the extrusion rod 211 via a connecting block 221. The end of the extrusion rod 211 is rotatably connected to an installation head 212. An elastically stressed extrusion head 213 is connected to the installation head 212. The connecting block 221 is connected to the installation head 212. The limiting rod 222 is connected to the connecting block 221. The limiting rod 222 slides through the displacement hole 106 and is parallel to the extrusion rod 211. The installation head 212 is rotatably connected to the end of the extrusion rod 211 to prevent the limiting rod 222 from rotating with the extrusion rod 211.

[0039] The transmission assembly 23 is sleeved on the extrusion rod 211 and connected to the clamping table 1 via a connector 231. A transmission component 232 is rotatably connected to the connector 231. The transmission component 232 includes a transmission cylinder 2321 rotatably sleeved on the connector 231, and a transmission gear A2322 is sleeved and connected to the transmission cylinder 2321. The connector 231 includes flanges 2311 bolted to both sides of the clamping table 1, and a fixing pipe 2312 is fixed to the flange 2311. The fixing pipe 2312 is correspondingly connected to the through hole 105. The transmission cylinder 2321 includes a connected movable mounting groove 23211 and a driving groove 23212. The diameter of the movable mounting groove 23211 is larger than the diameter of the driving groove 23212. The driving groove 23212 is an internally threaded groove. The fixed tube 2312 is connected in the movable mounting groove 23211. The transmission cylinder 2321 rotates on the fixed tube 2312. The fixed tube 2312 is sleeved on the extrusion rod 211 through the driving groove 23212, so that the rotation of the fixed tube 2312 drives the extrusion rod 211 to move through the thread.

[0040] The adjusting component 25 includes an adjusting rod 251 that passes through and connects to two supporting sliders 102. The adjusting rod 251 is provided with a transmission gear B252 near both ends. The transmission chain 24 is sleeved on multiple transmission gears A2322 and one transmission gear B252. The two supporting sliders 102 are provided with rotating holes 104. The adjusting rod 251 is rotatably connected to the two rotating holes 104. Both ends of the adjusting rod 251 are connected to a disc 253, which facilitates the operator to rotate the adjusting rod 251.

[0041] The positioning and locking assembly 3 includes multiple locking blocks 31 connected to the adjusting rod 251. The multiple locking blocks 31 are circumferentially distributed. A displacement block 32 is sleeved on the adjusting rod 251, and a locking hole 321 is opened through the displacement block 32. The locking hole 321 is engaged with the locking block 31. An anti-disengagement component 34 is provided on the adjusting rod 251. The anti-disengagement component 34 includes a square block 341 connected to the adjusting rod 251. A magnetic ring 342 is connected to the square block 341. The magnetic ring 342 is magnetically connected to the surface of the displacement block 32.

[0042] A folded block 103 is provided between the two support sliders 102. The displacement block 32 is slidably fitted into the inner right angle position of the folded block 103. A toggle rod 33 is connected to the displacement block 32 through a mounting part 331. The toggle rod 33 facilitates the operator to move the displacement block 32 to the inner right angle position of the folded block 103. The mounting part 331 includes a mounting block that is bolted to the displacement block 32, and an internal threaded tube is fixed on the mounting block. One end of the toggle rod 33 is connected to the internal threaded tube, so that the toggle rod 33 is connected to the displacement block 32.

[0043] Working principle: Rotating the flower disc 253 drives the adjusting rod 251 to rotate, which in turn drives the two transmission gears B252 to rotate. The two transmission gears B252 drive the two transmission chains 24 to rotate, which in turn drive the two rows of transmission gears A232 and the transmission cylinder 2321 to rotate on the fixed tube 2312. Since the limiting rod 222 slides through the displacement hole 106, when the transmission cylinder 2321 rotates, it drives the pressing rod 211 to rotate through the thread. The two rows of pressing rods 211 move relatively closer or relatively farther away in the through hole 105, and the limiting rod 222 moves in the displacement hole 106. Furthermore, the two rows of pressing rods 211 exert force on the wood through the elastic force-bearing pressing head 213. Then, the displacement is moved by the actuating rod 33. Block 32 slides and translates at a right angle within the folded block 103, and slides on the adjusting rod 251 to the position of the locking block 31, so that the locking hole 321 matches the locking block 31. In this way, the adjusting rod 251 is restricted from rotating by the displacement block 3232. The reason is that the displacement block 32 is restricted between the folded block 103 and the clamping table 1 and can only translate but not rotate. Therefore, when the displacement block 32 is fitted into the locking block 31 position of the adjusting rod 251 through the locking hole 321, the adjusting rod 251 cannot rotate. In addition, the magnetic connection between the displacement block 32 and the square block 341 and the magnetic ring 342 can keep the locking hole 321 and the locking block 31, preventing the displacement block 32 from slipping off the locking block 31 and preventing the locking hole 321 and the locking block 31 from separating, which would cause the adjusting rod 251 to loosen and rotate, thus affecting the pressure and compression effect on the wood.

[0044] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.

[0045] In the description of this utility model, it should be understood that the terms indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
