Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1-5 As shown, the present invention proposes a wood surface grooving machine, which includes a workbench 1. Two support blocks 2 are movably connected to the top of the workbench 1. The support blocks 2 are equipped with a fixing mechanism 3 inside. Two sets of position adjustment mechanisms 4 are provided on the top of the workbench 1. The two position adjustment mechanisms 4 are respectively connected to the two support blocks 2 and are used to adjust the position of the support blocks 2.

[0025] In this invention, two support blocks 2 and two sets of fixing mechanisms 3 can fix both ends of multiple timber squares, facilitating accurate grooving of the timber squares. During the grooving process, the displacement mechanism 8 enables the vertical plate 5, top block 6, and milling mechanism 7 to move in a translational motion, achieving precise cutting and continuous grooving. The position adjustment mechanism 4 can adjust the positions of the support blocks 2 and fixing mechanisms 3 respectively, thereby facilitating the fixing of timber squares of different lengths to meet the processing needs of timber squares of different lengths and expanding the applicability of the equipment.

[0026] In embodiment 1, the fixing mechanism 3 includes a drive box 31 installed on the outside of the support block 2. The support block 2 has multiple fixing cavities 32 inside. The drive box 31 is connected to the multiple fixing cavities 32. A round rod 33 is installed inside the fixing cavity 32. Two clamping blocks 34 are slidably connected to the outside of the round rod 33. Both clamping blocks 34 extend to the top of the support block 2. A push-pull plate 36 is slidably connected inside the drive box 31. The two clamping blocks 34 are hinged to the side of the drive box 31 near the drive box 31 by a pin. The other end of the two connecting rods 35 extends into the drive box 31 and is hinged to the outside of the push-pull plate 36 by a pin. A push-pull assembly 37 is provided inside the drive box 31. The push-pull assembly 37 is connected to the push-pull plate 36 and is used to drive the push-pull plate 36 to move.

[0027] When grooving is required on the timber, the timber is placed between the opposite sides of the two clamping blocks 34. Then, the push-pull assembly 37 drives the push-pull plate 36 to move away from the support block 2. Under the action of the two connecting rods 35 and the pin, the two clamping blocks 34 will move to the opposite side outside the round rod 33, so that the opposite side of the two clamping blocks 34 abuts against the outside of the timber, thus fixing the timber with the two clamping blocks 34.

[0028] In embodiment 2, the push-pull assembly 37 includes a first electric push rod 371 installed on the side of the drive box 31 away from the support block 2 and extending into it. The piston rod of the first electric push rod 371 is connected to the push-pull plate 36. Two first guide rods 372 extending to the outside of the drive box 31 are installed on the side of the push-pull plate 36 away from the support block 2. Both first guide rods 372 are slidably connected to the drive box 31.

[0029] When the first electric push rod 371 is activated, the piston rod of the first electric push rod 371 will drive the push-pull plate 36 to move away from or towards the support block 2. When the push-pull plate 36 moves away from the support block 2, the two clamping blocks 34 can move to opposite sides to clamp and fix the wood. When the push-pull plate 36 moves towards the support block 2, the two clamping blocks 34 can move to opposite sides to remove the grooved wood.

[0030] In embodiment 3, the position adjustment mechanism 4 includes four fixed ear plates 41 installed on the top of the workbench 1. A square adjustment rod 42 is installed between the opposite sides of two fixed ear plates 41 on the same side. A sliding frame 43 is slidably connected to the outside of the two square adjustment rods 42. A support block 2 is installed between the opposite sides of the two sliding frames 43. A positioning component 44 is provided on the top of each of the two sliding frames 43.

[0031] By sliding the two sliding frames 43 on the outside of the two square adjusting rods 42 respectively, the position of the support block 2 can be adjusted. By adjusting the position of the two support blocks 2, the distance between the two support blocks 2 can be adjusted, which makes it convenient to fix timber of different lengths to meet the processing needs of timber of different lengths and expands the application range of the equipment.

[0032] After the position of the support block 2 is adjusted, the sliding frame 43 can be positioned by the positioning component 44 to ensure the stability of the sliding frame 43 after the position adjustment, thereby further ensuring the stability of the support block 2 after the position adjustment.

[0033] In embodiment four, the positioning component 44 includes a threaded hole opened on the top of the sliding frame 43, and a threaded rod 441 is threadedly connected inside the threaded hole. The bottom of the threaded rod 441 abuts against the top of the square adjusting rod 42, and a knob 442 is installed on the top of the threaded rod 441.

[0034] When the knob 442 is turned, the knob 442 will drive the threaded rod 441 to move up or down. When the threaded rod 441 moves up and disengages from the square adjusting rod 42, the sliding frame 43 can be moved, thereby adjusting the position of the support block 2. After the adjustment is completed, the knob 442 is turned in the opposite direction, causing the threaded rod 441 to move down. When the bottom end of the threaded rod 441 abuts against the top of the square adjusting rod 42, the sliding frame 43 can be positioned to ensure the stability of the sliding frame 43 after adjustment.

[0035] In embodiment 5, the milling mechanism 7 includes a fixed frame 71 installed on one side of the top block 6. A lifting block 72 is slidably connected inside the fixed frame 71. A second electric push rod 73 extending into the top of the fixed frame 71 is installed. The piston rod of the second electric push rod 73 is connected to the top of the lifting block 72. Two second guide rods 74 extending into the top of the fixed frame 71 are installed on the top of the lifting block 72. Both second guide rods 74 are slidably connected to the fixed frame 71. Two connecting blocks 75 are provided on the side of the lifting block 72 away from the top block 6. A milling box 76 is installed on the other side of the two connecting blocks 75. Multiple milling machines 77 are provided inside the milling box 76.

[0036] When the second electric push rod 73 is activated, the piston rod of the second electric push rod 73 will drive the lifting block 72 to move downward. The lifting block 72 will drive the two connecting blocks 75 to move downward. The two connecting blocks 75 will drive the milling box 76 to move downward. The milling box 76 will drive multiple milling machines 77 to move downward, so that the milling machines 77 can enter the wood and mill the wood. The lifting block 72 can be guided by the two second guide rods 74 to ensure the stability of the lifting block 72 during the lifting movement.

[0037] The grooving machine 77 includes a grooving motor and a grooving cutter. By starting the grooving motor, the grooving cutter can be rotated. The rotation of the grooving cutter can groove the timber. During the grooving process, the displacement mechanism 8 can make the two vertical plates 5 move horizontally, thereby making the top block 6 and the grooving mechanism 7 move horizontally, so that the grooving machine 77 moves horizontally. After the grooving cutter moves downward and enters the interior of the timber, the grooving machine can groove the timber through the rotation and horizontal movement of the grooving cutter.

[0038] Multiple milling machines 77 correspond to multiple fixed cavities 32 respectively, so that multiple milling machines 77 can be located above multiple timber blocks, and multiple milling machines 77 can mill grooves on multiple timber blocks respectively.

[0039] In embodiment six, the displacement mechanism 8 includes an I-shaped plate 81 installed at the bottom of the worktable 1, a ball screw drive assembly 82 installed at the top of the I-shaped plate 81, a displacement plate 83 installed at the output end of the ball screw drive assembly 82, the bottoms of the two vertical plates 5 are connected to the top of the displacement plate 83, and two sets of guide assemblies 84 are provided on the outer side of the worktable 1.

[0040] The workbench 1 has bases installed at its four bottom corners. An I-shaped plate 81 is installed between the four bases. The ball screw drive assembly 82 can be installed through the I-shaped plate 81. The ball screw drive assembly 82 includes a U-shaped frame, a drive motor, a ball screw, a drive block, and two guide rails. The U-shaped frame is installed on the top of the I-shaped plate 81. The drive motor is installed on one side of the U-shaped frame. The ball screw is installed on the output shaft of the drive motor and extends into the U-shaped frame. The drive block is installed on the output end of the ball screw. The top of the drive block is connected to the bottom of the displacement plate 83. The two guide rails are installed on the inner bottom wall of the U-shaped frame. The drive block is slidably connected to the outside of the two guide rails. When the drive motor is started, the output shaft of the drive motor will drive the ball screw to perform translational movement, thereby causing the drive block to drive the displacement plate 83 to perform translational movement.

[0041] The displacement plate 83 will drive the two vertical plates 5, the top block 6 and the milling mechanism 7 to move in translation, thereby adjusting the milling position of the milling machine 77 and facilitating the milling of timber.

[0042] In embodiment seven, the guide assembly 84 includes two guide lugs 841 installed on the outside of the workbench 1, and a slide rod 842 is installed between the opposite sides of the two guide lugs 841. Two vertical plates 5 are slidably connected to the outside of the two slide rods 842 respectively.

[0043] The vertical plate 5 can be guided and supported by two guide plates 841 and a slide bar 842 to ensure the stability of the movement of the vertical plate 5.

[0044] In embodiment seven, a PCL controller is provided on the outer end face of the workbench 1. The first electric push rod 371, the second electric push rod 73, the milling machine 77, and the ball screw drive assembly 82 are all electrically connected to the PCL controller. The first electric push rod 371, the second electric push rod 73, the milling machine 77, and the ball screw drive assembly 82 can be programmed through the PCL controller.

[0045] Working principle: When using this timber grooving machine, first, according to the length of the timber to be processed, loosen the knobs 442 of the two positioning components 44, manually slide the two support blocks 2 to the appropriate position, and then tighten the knobs 442 to fix them. Place the timber on the two support blocks 2, start the first electric push rod 371 of the fixing mechanism 3 to drive the push-pull plate 36 to move, and drive all the clamping blocks 34 to move synchronously through the connecting rod 35 to firmly clamp the timber. Then, according to the processing requirements, start the ball screw drive component 82 of the displacement mechanism 8 to move the grooving machine 77 to the position to be grooved, and then start... The second electric push rod 73 of the grooving mechanism 7 and the grooving machine 77 lower the grooving cutter of the grooving machine 77 to a predetermined depth. Then, the ball screw drive assembly 82 of the displacement mechanism 8 is activated, and the grooving mechanism 7 can move smoothly along the length of the timber to perform precise grooving. After one grooving is completed, the second electric push rod 73 is activated in reverse to disengage the grooving cutter of the grooving machine 77 from the timber. Then, the ball screw drive assembly 82 of the displacement mechanism 8 is activated again to move the grooving machine 77 to the next grooving position. The above operation can be repeated to perform continuous grooving.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
