DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a double-end mortise and tenon processing center, including a machine body 1 and two bases 2 arranged relatively on the machine body 1, and a mortise and tenon processing mechanism 3, a wood clamping mechanism 4, a feeding bin 5, a receiving bin 8, and a feeding mechanism 6 for taking and placing the wood in the feeding bin 5 one by one onto the wood clamping mechanism 4 are respectively arranged between the two bases 2. The wood clamping mechanism 4 is located on the inner side of the mortise and tenon processing mechanism 3, and the mortise and tenon processing mechanism 3 is suitable for processing the tenons or mortises at both ends of the wood on the wood clamping mechanism 4. The receiving bin 8 is located at the lower side of the wood clamping mechanism 4, and an inclined material guide rod 7 is arranged between the wood clamping mechanism 4 and the receiving bin 8. When the wood clamping mechanism 4 releases the wood, the wood can slide into the receiving bin 8 along the inclined material guide rod 7. A PLC controller is also included, and the mortise and tenon processing mechanism 3, the wood clamping mechanism 4, and the feeding mechanism 6 are electrically connected to the PLC controller respectively.

[0024] When the above-mentioned double-end mortise and tenon processing center is working, the wood to be processed is placed in the feeding bin 5, and the feeding mechanism 6 pushes the wood in the feeding bin 5 to the wood clamping mechanism 4. After the wood clamping mechanism 4 clamps and fixes the wood, the mortise and tenon processing mechanism 3 processes the tenon or mortise groove at both ends of the wood. When the wood processing is completed, the wood clamping mechanism 4 releases the processed wood, and the wood slides into the receiving bin 8 along the inclined guide rod 7 under its own gravity.

[0025] In the above method, through the arrangement of the mortise and tenon processing mechanism 3, the wood clamping mechanism 4, the feed bin 5, the receiving bin 8 and the feeding mechanism 6, automatic loading, automatic clamping, automatic processing of tenons or mortise grooves and automatic unloading of wood are realized, which has the advantage of a high degree of automation and effectively improves work efficiency.

[0026] In this embodiment, Figure 1 , Figure 2 and Figure 6 As shown, one of the bases 2 is fixedly connected to the fuselage 1, and the other base 2 is slidably connected to the fuselage 1 along the Y-axis direction. The fuselage 1 is provided with a first driving member 9 for driving the other base 2 to slide. The first driving member 9 specifically includes a screw rod rotatably connected to the fuselage 1, a fourth motor fixed to the fuselage 1, and a nut sleeve fixed to the other base 2, and the nut sleeve is threadedly connected to the screw rod. The mortise and tenon processing mechanism 3 includes two mortise and tenon processing components 31 relatively arranged on the two bases 2, the wood clamping mechanism 4 includes two wood clamping components 41 relatively arranged on the two bases 2, and the two ends of the wood can be clamped in the two wood clamping components 41 respectively, the feeding bin 5 includes two feeding troughs 51 relatively arranged on the base 2, the receiving bin 8 includes two receiving troughs 81 relatively arranged on the two bases 2, and the feeding mechanism 6 includes two feeding components 61 relatively arranged on the base 2.

[0027] Through the above arrangement, the other base 2 can slide toward one of the bases 2, so that the spacing between the mortise and tenon processing assembly 31, the wood clamping assembly 41, the feed trough 51 and the receiving trough 81 can be adjusted, so as to be suitable for wood of different lengths.

[0028] In this embodiment, Figures 3 to 5As shown, the mortise and tenon processing assembly 31 includes a horizontal support platform 311 connected to the base 2 and rotating along the horizontal plane, and a first arc-shaped rack 312 is fixedly connected to the outer side of the horizontal support platform 311, and a first motor is fixed on the fuselage 1, and a first gear 320 is fixed on the output end of the first motor, and the first gear 320 is meshed with the first arc-shaped rack 312. The first motor can drive the horizontal support platform 311 to rotate a certain angle in the horizontal plane, so that the tenon processing module and the tenon groove processing module can be rotated to the target position, better contact with the wood, and make the processing accuracy of the wood higher. An XY axis linear module 313 is fixed on the horizontal support platform 311, and a longitudinal bracket 314 is fixed on the output end of the XY axis linear module 313. The XY axis linear mold body includes an X axis linear motor and a Y axis linear motor fixed on the output end of the X axis linear motor. The XY axis linear mold can drive the tenon processing module and the tenon groove processing module to move along the X axis and Y axis directions to better align them with the wood. The longitudinal bracket 314 is connected to a mounting plate 315 for rotation in the longitudinal plane. The longitudinal bracket 314 is provided with a rotation slot. The mounting plate 315 is provided with a rotation part that can be adapted to the rotation slot. The longitudinal bracket 314 is fixed with a second arc-shaped rack 316. The mounting plate 315 is fixed with a second motor 3202. The output end of the second motor 3202 is fixed with a second gear 317. The second gear 317 is meshed with the second arc-shaped rack 316. The second gear 317 and the second arc-shaped rack 316 can drive the tenon processing module and the tenon groove processing module to adjust the pitch angle. The mounting plate 315 is fixed with a Z-axis linear module 318. The output end of the Z-axis linear module 318 is fixed with a connecting plate 319. The connecting plate 319 is respectively provided with a tenon processing module and a tenon groove processing module.

[0029] When the above-mentioned mortise and tenon processing assembly 31 is working, the tenon processing module or the tenon groove processing module is linked along the X-axis, Y-axis, and Z-axis, and the angles in the horizontal plane and the vertical plane are adjusted as needed to realize the processing of the tenon or the tenon groove at the end of the wood. Through multi-degree-of-freedom movement, the tenon or the tenon groove with higher precision can be processed.

[0030] In this embodiment, Figure 3 and Figure 4As shown, the tenon processing module includes a second motor 3202 fixed on a connecting plate 319 and a grinding head 3201 fixed on an output end of the second motor 3202, the grinding head 3201 extending to one side of the wood clamping mechanism 4, the mortise and tenon processing module includes a third motor 3302 slidably connected to the connecting plate 319, a telescopic electric cylinder 3303 fixed on the connecting plate 319 and a mortise and tenon cutter 3301 fixed on an output end of the third motor 3302, the output end of the telescopic electric cylinder 3303 is fixedly connected to the third motor 3302, and the connecting plate 319 is provided with a through slot through which the third motor 3302 can partially extend.

[0031] In the above arrangement, when processing the tenon, the telescopic electric cylinder 3303 drives the tenon groove to retreat to one side of the through groove, which will not interfere with the movement of the grinding head 3201. The grinding head 3201 rotates and moves from the outside to the inside to process the tenon at the end of the wood. When processing the tenon groove, the tenon groove cutter 3301 rotates and extends into the wood to complete the processing of the tenon groove. The processing of the tenon and the tenon groove is taken into account at the same time, which has the advantage of good applicability.

[0032] In this embodiment, Figure 3 and Figure 4 As shown, the wood clamping assembly 41 includes a support frame 411 fixed on the base 2, an upper clamping block 412 and a lower clamping block 413 slidably connected to the support frame 411 through a guide shaft, and a first cylinder 414 that can drive the upper clamping block 412 to slide up and down, and a second cylinder 415 that can drive the lower clamping block 413 to slide up and down. A clamping groove for clamping wood is formed between the upper clamping block 412 and the lower clamping block 413, and the opening of the clamping groove is arranged toward the feeding mechanism 6. The inclined guide rod 7 extends to one side of the lower clamping block 413. When the lower clamping block 413 slides downward to the lowest position, the wood can contact the inclined guide rod 7.

[0033] When the above-mentioned wood clamping assembly 41 is working, the feeding mechanism 6 pushes the wood into the clamping grooves of the two clamping assemblies, the first cylinder 414 drives the upper clamping block 412 downward, and the second cylinder 415 drives the lower clamping block 413 upward, thereby clamping the wood. After processing, the second cylinder 415 drives the lower clamping block 413 downward. When the lower clamping block 413 moves downward to the lowest position, the wood slides into the collecting bin 8 along the inclined guide rod 7 under its own gravity.

[0034] In the above arrangement, the automatic unloading of wood is achieved by arranging the inclined material guide rod 7, which has the advantages of simple and compact structure and good unloading effect.

[0035] In this embodiment, Figure 6As shown, the feeding assembly 61 includes a feeding support plate 611 fixed on the base 2, a feeding hand 612 slidably connected to the feeding support plate 611 along the X-axis direction, a second driving member 613 for driving the feeding hand 612 to slide, a rear stopper 614 fixed to the rear side of the feeding hand 612, a front stopper 615 hinged to the front side of the feeding hand 612, and a third cylinder 616 hinged between the lower side of the feeding hand 612 and the lower side of the front stopper 615, and the front stopper 615 can be deflected to one side or below the top plane of the feeding hand 612 under the drive of the third cylinder 616. The second driving assembly may specifically include two synchronous wheels rotatably connected to the two ends of the feeding support plate 611, a synchronous belt drivingly connected between the two synchronous wheels, and a driving motor arranged on the feeding support plate 611 for driving any one of the synchronous wheels to rotate, and one side of the synchronous belt is clamped and fixed to the feeding hand 612.

[0036] When the above-mentioned feeding assembly 61 is working, the wood falls from the feeding bin 5 onto the feeding support hand 612 located between the front stop block 615 and the rear stop block 614, and the second driving member 613 drives the feeding support hand 612 to move toward the clamping groove of the wood clamping assembly 41. When the wood enters the clamping groove, the third cylinder 616 drives the front stop block 615 to deflect to the bottom of the feeding support hand 612. When the wood clamping assembly 41 clamps the wood, the feeding support hand 612 resets and retracts.

[0037] In this embodiment, Figure 6 and Figure 7 As shown, the feeding trough body 51 includes a longitudinally arranged bottom plate 511 and two side plates 512, the two side plates 512 are respectively located on both sides of the bottom plate 511, and a lower support plate 513 is slidably connected to the bottom plate 511 below the two side plates 512, and a fourth cylinder 514 is provided on the bottom plate 511 for driving the lower support plate 513 to slide longitudinally, and the lower support plate 513 can slide below or above the feeding support hand 612, and a fifth cylinder 515 is provided on any one of the side plates 512 above the lower support plate 513, and the piston rod of the fifth cylinder 515 can press the wood tightly into the feeding trough body 51 or release it onto the lower support plate 513.

[0038] When the above-mentioned feeding trough body 51 is working, when the bottom layer of wood is against the lower support plate 513, the fourth cylinder 514 presses the penultimate layer of wood tightly against the feeding trough body 51 to limit the penultimate layer and the wood above it. The fourth cylinder 514 can drive the bottom layer of wood downward and finally release it onto the feeding support hand 612.

[0039] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
