[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the attached Figures 1-5 , without limiting the scope of the present utility model. It should be understood that these descriptions are merely exemplary. In addition, in the following description, the descriptions of well - known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0022] A multi - head mortising machine with a hydraulic system provided by the present utility model includes a lifting table 2 for driving the wood to move up and down. The lifting table 2 moves under the drive of the hydraulic system. The hydraulic system includes a hydraulic cylinder 3 arranged at the bottom of the lifting table 2. The oil inlet 20 and the oil outlet 21 of the hydraulic cylinder 3 are respectively connected to the hydraulic regulating valve of the hydraulic station. The hydraulic station 7 is electrically connected to the control system 1, and the control system 1 is connected to a foot - operated switch 19. When the staff presses the switch, the control system drives the hydraulic station to operate. The hydraulic station supplies hydraulic oil to the hydraulic cylinder. After the foot - operated switch is pressed, the hydraulic cylinder drives the lifting table to descend and ascend once, realizing the mortising of the wood. Through the setting of the hydraulic system structure, the stability and efficiency of the movement of the lifting table are ensured.

[0023] The lifting table 2 moves on the main body of the mortising machine. A limit switch is arranged on the main body of the mortising machine. A touch rod 4 corresponding to the limit switch is arranged at the bottom of the lifting table 2. The limit switch is electrically connected to the control system 1. The limit switch includes an upper limit switch 10 and a lower limit switch 5. The lower limit switch 5 corresponds to the bottom of the touch rod 4, and the upper limit switch 10 corresponds to the top of the touch rod 4. When the hydraulic system drives the lifting table to descend, the bottom of the touch rod continuously approaches the lower limit switch. When the bottom of the touch rod contacts the lower limit switch, the lower limit switch transmits a rising signal to the control system. The control system issues an order to the hydraulic system, and the hydraulic system drives the lifting table to ascend. When the top of the touch rod contacts the upper limit switch, the control system commands the hydraulic system to stop operating, completing the work of one mortising. The degree of automation is high, and there is no need for manual control of the descending and ascending height of the lifting table, improving the work efficiency.

[0024] The tenoning machine comprises a tenoning machine main body and a material pressing and lifting system. The material pressing and lifting system includes a lifting table 2 and a material pressing unit arranged on the lifting table. The tenoning machine main body includes a tenoning machine support base 33 and a tenoning machine unit 11 arranged on the tenoning machine support base 33. The tenoning machine unit 11 includes a tenoning machine housing and a multi-head tenoning component arranged in the tenoning machine housing. A locking unit 12 is arranged on the tenoning machine housing. The locking unit 12 corresponds to a locking hole on a rotating shaft 27. The lifting table 2 moves back and forth on the tenoning machine support base. The limit switch is arranged on the tenoning machine support base.

[0025] The locking unit 12 includes a lower locking seat 16 and an upper locking seat 15 arranged on the lower locking seat 16. A locking rod 13 is slidably arranged at the centers of the lower locking seat 16 and the upper locking seat 15. A retaining rod is arranged on the locking rod 13. An upper retaining groove 14 corresponding to the retaining rod is arranged on the upper locking seat 16. A lower retaining groove 18 corresponding to the retaining rod is arranged on the lower locking seat 16. A return spring 17 is arranged between the locking rod 13 and the lower locking seat 16. When operating normally, the retaining rod is arranged in the upper retaining groove. When it is necessary to disassemble the multi-head tenoning component, the locking rod is pulled upward to move the retaining rod out of the upper retaining groove, and the locking rod is rotated to make the retaining rod correspond to the lower retaining groove. At this time, the lower end of the locking rod is inserted into the locking hole, which is convenient for replacement.

[0026] The tenoning machine main body is provided with a multi-head tenoning component that is convenient for replacement. The multi-head tenoning component includes a rotating shaft 27. One end of the rotating shaft 27 is provided with a small pulley 29. The small pulley 29 is connected to a large pulley of a motor 6 through a belt 9. The other end of the rotating shaft 27 is provided with a sliding mounting unit. The sliding mounting unit is arranged on a disassembly and assembly cover of the tenoning machine main body. The disassembly and assembly cover is connected to the tenoning machine main body through connecting bolts. A bushing 28 is sleeved on the rotating shaft 27. A tenoning cutter set is arranged on the bushing 28. First locking nuts 26 are arranged at both ends of the bushing 28. Through the arrangement of the first locking nuts, the bushing 28 is fixedly arranged on the rotating shaft 27. A second locking nut 34 for fixing the tenoning cutter set is arranged on the bushing 28. After the tenoning cutter set is sleeved on the bushing 28, the second locking nuts arranged on both sides can fix the tenoning cutter set.

[0027] The sliding mounting unit includes a support 25 sleeved on the end of a rotating shaft 27. A gland 32 is provided at the end of the support 25. A bearing 31 is provided between the gland 32 and the support 25. Both the gland 32 and the support 25 are arranged in a sliding mounting seat 24. A bearing is provided between the support 25 and the sliding mounting seat 24. A gland 30 is screwed on the sliding mounting seat 24. A connection hole allowing the rotating shaft to pass through is provided at the center of the gland 30. The setting of the gland 30 can prevent dust and impurities from entering the interior of the sliding mounting unit and hindering the rotation of the rotating shaft 27. A tightening screw rod 23 is screwed on the sliding mounting seat. One end of the tightening screw rod 23 is in contact with the gland 32, and a rotating handle 22 is provided at the other end of the tightening screw rod 23. When it is necessary to adjust the distance between the sliding mounting unit and the rotating shaft, the gland is urged to move in the sliding mounting seat by rotating the tightening screw rod.

[0028] When it is necessary to replace the mortising cutter group on the multi-head mortising component, first remove the connection bolts, and then remove the sliding mounting unit. Rotate the first locking nut, so that the mortising cutter group can be removed for replacement.

[0029] By providing a hydraulic system, the present utility model improves the up-and-down movement speed and stability of the lifting table. At the same time, the provided multi-head mortising component can quickly replace the multi-mortising cutters, saving the maintenance time and improving the work efficiency.
