Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a double-end automatic tenoning machine for plates. Background Art

[0002] During the processing of wooden boards, sometimes tenons need to be machined at both ends of the board, so a tenoning device is required to perform the tenoning process on both ends of the board. For example, the invention patent with publication number CN112356184B discloses a double-end tenoning device for wood used in furniture production. The device uses a transmission assembly to allow workers to complete the tenoning without manually moving the wood. Subsequently, a cutting assembly can intermittently cut the wood, eliminating the need for workers to manually operate the cutting equipment to tenon, thereby avoiding the tenoning not meeting the requirements and wasting raw materials. A clamping assembly allows the cutting assembly to manually fix the wood while tenoning. Finally, a feeding assembly and a discharge rail allow the feeding assembly to intermittently transport the wood to the transmission assembly. At the same time, the discharge rail can transport the tenoned wood to a collection basket, eliminating the need for workers to manually unload the wood. However, the conveying structure for conveying the wood in this device is a single conveyor belt arranged along a straight line, which results in the overall length of the device being relatively long. Therefore, it requires a large amount of storage space when in use, making it unsuitable for use in processing plants with limited space. Summary of the Invention

A storage space for storing plates can be constructed between the two frames 26, and the top of the storage space has the feed port 10, and the bottom has the discharge port 11. In addition, in order to facilitate the disassembly and assembly of the frames 26, a fixing plate 27 can be provided at the lower end of the two frames 26, and the fixing plate 27 is screwed in The bolt is detachably fixed on the machine base 1, and the cross-section of the frame 26 is U-shaped, and the side openings of the frame 26 are arranged to face each other, so that a storage space for placing plates can be constructed between the two frames 26, and the storage space is matched with the size of the plates, so that when the plates are stacked and placed in the storage space, the plates can be effectively limited. At the same time, the height of the discharge port 11 is greater than the thickness of one plate and less than the thickness of two plates. The plates can be stacked in the storage space from bottom to top. When feeding, the feeding mechanism 2 can only push out the plate at the bottom of the stacked storage rack 9 at a time. In addition, in the present embodiment, a jacking device can be provided at the bottom of the two frames 26, and the jacking device can be used to lift the plates in the frames 26 upward to a certain height, so that when the feeding device moves along the feeding track 6 to the bottom of the storage rack 9 after conveying a plate, the plate will not block the feeding device. The jacking device can adopt a structure in which a cylinder drives the jacking block to move up and down to realize the jacking of the plate, and the jacking device is also connected to a position sensing device for detecting the position of the feeding device. When the feeding device conveys the plate to the clamping mechanism 3 and approaches the bottom of the storage rack 9, the position sensing device can control the jacking device to lift the plate upward. When the feeding device moves to the bottom of the storage rack 9, the position sensing device can control the jacking device to move downward, so that the plate moves downward to the feeding device under the action of its own weight, so as to facilitate the feeding device to convey the plate.

[0024] In the present application, the feeding device includes a slide 12 slidably arranged on the feeding track 6, a driving structure for driving the slide 12 to move along the feeding track 6, and a clamping assembly 13 installed on the slide 12 for clamping the plate. Specifically, there are two slides 12, and the two slides 12 are slidably and symmetrically installed on the two tracks. During processing, the driving structure drives the slide 12 to move to the bottom of the material rack 26, and the two clamping assemblies 13 on the two slides 12 clamp the two ends of a plate placed at the bottom of the storage space, and then the driving device drives the slide 12 to move toward the clamping mechanism 3. Preferably, the driving structure can adopt the cylinder driving mechanism in the prior art, or the conveyor chain driving structure in the prior art. Since the driving structure is a prior art, it will not be described in detail here. Furthermore, the clamping assembly 13 includes a first driving cylinder 14, a fixed clamping block 15 and a movable clamping block 16. The fixed clamping block 15 is fixedly mounted on the front end of the slide 12. A rotating head 17 is mounted on the piston rod of the first driving cylinder 14. One end of the movable clamping block 16 is mounted on the rotating head 17. The first driving cylinder 14 can drive the movable clamping block 16 to move toward or away from the fixed clamping block 15, so that the movable clamping block 16 cooperates with the fixed clamping block 15 to clamp the plate. Specifically, when conveying the plate, the movable clamping block 16 is driven to rotate by the rotating head 17 so that the other end of the movable clamping block 16 is set upward. , and then the first driving cylinder 14 drives the movable clamping block 16 to move toward the fixed clamping block 15, and cooperates with the fixed clamping block 15 to clamp the plate. Finally, the driving structure drives the slide 12 to move toward the clamping mechanism 3. When the plate is transported to the clamping mechanism 3, the first driving cylinder 14 drives the movable clamping block 16 to move back to the fixed clamping block 15, and drives the movable clamping block 16 to rotate through the rotating head 17, so that the other end of the movable clamping block 16 is set downward, thereby loosening the plate, and then the driving structure drives the slide 12 to move to the bottom of the storage rack 9 so that the next plate can be transported. In a more preferred embodiment of the present application, since the feed track 6 is arranged to be inclined upward, an adjustment seat 28 can be provided at the front end of the slide 12, and the clamping assembly 13 is provided on the adjustment seat 28. The adjustment seat 28 rotates with the slide 12 and is connected to an adjustment cylinder. When the slide 12 moves to the uppermost end of the feed track 6, the adjustment seat 28 can be driven by the adjustment cylinder to rotate relative to the slide 12 so that the adjustment seat 28 is arranged horizontally, so that the clamping assembly 13 can transport the plate horizontally to the clamping mechanism 3, so that the clamping mechanism 3 can clamp the plate.

[0025] In the present application, the clamping mechanism 3 includes two clamping assemblies 18 for respectively clamping the two ends of the plate. The two clamping assemblies 18 each include an upper clamping plate 19 and a lower clamping plate 20. The upper clamping plate 19 is fixedly mounted on the machine base 1, and the lower clamping plate 20 is connected to a second driving cylinder 21. The second driving cylinder 21 can drive the lower clamping plate 20 toward or away from the upper clamping plate 19 to move so that the lower clamping plate 20 cooperates with the upper clamping plate 19 to clamp or loosen the end of the plate. When the feeding device conveys the plate between the upper clamping plate 19 and the lower clamping plate 20, the second driving cylinder 21 can drive the lower clamping plate 20 to move toward or away from the upper clamping plate 19. 20 moves toward the upper clamping plate 19, thereby clamping the two ends of the plate. When the mortising mechanism 4 completes the mortising process, the discharging mechanism 5 moves to the bottom of the clamping mechanism 3, and then the second driving cylinder 21 drives the lower clamping plate 20 to move back to the upper clamping plate 19. At this time, the lower clamping plate 20 supports the plate and places the plate on the discharging mechanism 5 during the downward movement, so that the discharging mechanism 5 can transport the plate to the placing table 7 for placement, and in order to facilitate the positioning of the plate, a positioning plate can be installed on the upper clamping plate 19 to facilitate the positioning of the plate transported by the feeding device.

[0026] It should be noted that the mortising device used in the present application is an existing structure. Specifically, the mortising device includes a tool holder 27 movably arranged on the machine base 1, and a driving device for driving the tool holder 27 to move. A tool 22 for mortising is provided on the tool holder 27. Since the plate of the present application needs to be mortised at both ends, the shape of the mortise is a circle of grooves arranged around the end of the plate. Therefore, the driving device needs to drive the tool holder 27 to move around the center of the end of the plate during the processing process, so that the tool 22 on the tool holder 27 can perform circumferential milling processing on the end of the plate to process the required tenon at both ends of the plate.

[0027] In another specific embodiment of the present application, the discharge device may include a support rod 23 that is slidably matched with the discharge track 8, the support rod 23 is connected to a driving component that drives it to move toward or back to the clamping mechanism 3, and a push block 25 is provided at one end of the support rod 23 facing the clamping mechanism 3. The driving component may adopt a cylinder driving structure, the piston rod of the cylinder driving structure is connected to the support rod 23, and the support rod 23 is driven to move toward or back to the clamping mechanism 3 by controlling the extension and contraction of the piston rod, or the driving component may adopt a gear driving structure, and the bottom of the support rod 23 is provided with a gear along its length. The tooth surface, the gears of the gear drive structure are meshed with the tooth surface, and the gears are controlled to rotate by the motor, thereby driving the support rod 23 to move toward or away from the clamping mechanism 3. When the mortising mechanism 4 completes the mortising process, the two support rods 23 are driven toward the clamping mechanism 3 by the third driving cylinder 24. The clamping mechanism 3 loosens the plate, and the loosened plate falls onto the support rod 23. Then, the two support rods 23 are driven toward the placing table 7 by the third driving cylinder 24, so that the push block 25 on the support rod 23 pushes the plate toward the placing table 7 to push the plate onto the placing table 7 for placement.

[0028] Preferably, the placement table 7 includes two pedestals respectively used to support the two ends of the plate, and the two pedestals are symmetrically provided with discharge tracks 8 on the side facing each other. The two discharge tracks 8 are both arranged along the length direction of the pedestals, and support rods 23 are provided on the two discharge tracks. The two support rods 23 can support and push the two ends of the plate respectively, thereby improving the stability of the plate during the pushing process. At the same time, when the plate is placed, the two ends of the plate are supported by the two pedestals, which can also improve the stability of the plate placement.

[0029] The utility model is a double-end automatic tenoning machine for plates, which adopts a conveying structure arranged in upper and lower layers. An upward inclined feed track 6 is set on the machine base 1 for conveying the plates to the clamping mechanism 3 for tenoning processing, and a horizontal placement table 7 is set directly above the feed track 6 for placing the processed plates. At the same time, a discharge track 8 is set on the side of the placement table 7 for conveying the plates processed on the clamping mechanism 3 to the placement table 7.
