Description

Technical Field

[0001] The present invention relates to the technical field related to door panel frames, and in particular to a 45-degree automatic tenoning device for a door panel frame and a processing method thereof. Background Art

[0002] A tenoning machine is a cutting tool used to process pins and pin grooves on wooden boards. However, with the development of science and technology, people have higher and higher requirements for tenoning machines, resulting in that traditional tenoning machines can no longer meet people's needs. Existing tenoning machines have certain disadvantages when used. First, the existing tenoning machines cannot process workpieces with a certain angle very well, which makes the tenoning machines have certain limitations in processing wooden boards. Secondly, the tenoning machines usually position the wooden boards by hand, and the poor positioning accuracy will inevitably cause certain dangers to people. At the same time, the tenoning machine cannot process the tenon and the tenon groove at the same time, which often causes a mismatch in quantity. Finally, when one of the wooden boards is assembled with the tenon groove on the other wooden board through the tenon, in order to ensure the flatness and firmness of the assembly surface, the assembly groove at the edge of one of the wooden boards often needs to match the assembly groove at the end of the other wooden board, while the existing tenoning machines can only process the mortise and tenon structure, and cannot make the assembly groove at the same time, and have a single function. Summary of the invention

[0003] The present invention aims to overcome the deficiency of single function of the tenoning machine in the prior art and provides a multifunctional 45-degree automatic tenoning device for door panel frame and a processing method thereof.

[0043] like Figure 1 and Figure 2 As shown, the present invention also provides a method for processing a 45-degree automatic tenoning device for a door panel frame, comprising the following steps:

[0044] Step 1: Control the relevant buttons on the operation panel 8 to start the linear cylinder 23 to move the limit block down to a suitable position;

[0045] Step 2: Place two wooden board blanks on two L-shaped plates 30 respectively, push the wooden board blanks toward the limit block until their ends contact the corresponding limit plates 24, and then clamp the wooden board blanks through the corresponding moving plates 31, and the linear cylinder 23 drives the limit block to move up and separate from the wooden board blanks;

[0046] Step 3, start the linear cylinder 5 35, and the linear cylinder 5 35 drives the pressing block 36 to move downward to press the wooden board blank;

[0047] Step 4, start the linear cylinder 3 18 and the motor 2 21, the motor 2 21 drives the cutting disc 20 to rotate, and the linear cylinder 3 18 drives the motor 2 21 and the cutting disc 20 to cut the end of the wooden board blank;

[0048] Step 5, start the linear cylinder 6 37, the linear cylinder 6 37 drives the propulsion block 38 to move toward one side of the wooden board blank until the two cutting blades 45 are respectively located on the upper and lower sides of the corresponding wooden board blank, start the rotary cylinder 40 and the linear cylinder 7 41, drive the drill bit 42 to rotate and advance toward the corresponding wooden board blank to drill a hole, start the linear cylinder 8 51 at the same time, drive the upper and lower cutting blades 45 to move closer to each other for cutting, until the two cutting blades 45 contact each other, start the linear cylinder 6 37 again to move in the opposite direction, as shown in FIG. Figure 7 As shown, one of the wooden board blanks is cut up and down by a cutting blade 45 to form a tenon 54, and the other wooden board blank is drilled by a drill bit 42 to form a tenon groove matching the tenon 54;

[0049] Step 6: Start the linear cylinder 15, which drives the dust cover 11 to move to a suitable position. Figure 7 As shown, it is convenient for the notching cutter disc 13 to cut the assembly groove 55 at the end of the wooden board blank;

[0050] Step 7, start the motor 12, the motor 12 drives the corresponding groove cutter disc 13 to rotate, start the linear cylinder 7, the linear cylinder 7 drives the wooden blank on the working platform 2 to move to the left, and during the movement, the groove cutter disc 13 rotates at high speed, such as Figure 7 As shown, a mounting groove 55 is cut at the end of the wooden board blank.

[0051] The present invention is mainly used for processing the mortise and tenon structure on the 45-degree end face of the door panel frame, and the shape of the wooden board blank is rectangular. The operator first pulls the movable plate 31 outward, and places the wooden board blank on the L-shaped plate 30, and at the same time fully contacts the end of the wooden board blank with the corresponding limit plate 24 to ensure that the two wooden board blanks are perpendicular to each other, and then loosens the movable plate 31.
