Description

Technical Field

[0001] This utility model belongs to the field of tenoning machine technology, and in particular relates to a multi-head tenoning machine. Background Technology

[0002] When processing wood, tenoning is required to facilitate subsequent splicing and assembly. To prevent the wood from shifting during tenoning, a positioning device is needed to clamp and fix it. While existing positioning devices can meet the needs of fixing wood, they still have shortcomings in use. For example, existing positioning devices are not easy to adjust and can only fix wood of a fixed size, limiting their application. Therefore, we propose a wood tenoning positioning device to solve the above-mentioned problems. Utility Model Content

[0018] Figure 2 This is a left view according to one embodiment of the present invention. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with specific embodiments and the appendix, provides further details. Figure 1-2 The present invention will be described in further detail below. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the present invention.

[0020] This utility model provides a multi-head tenoning machine, including a lifting pressure device and a tenoning device. The lifting pressure device presses the wooden board tightly, and then places the pressed wooden board at the tenoning position of the tenoning device for tenoning. It has a high degree of automation and can prevent the wooden board from shifting during the tenoning process.

[0021] The lifting pressure device includes a lifting platform, which includes a lifting platform cylinder 9 mounted on the base of the tenoning machine. The telescopic end of the lifting platform cylinder 9 is connected to the worktable 8. A sliding base is provided at the bottom of the lifting platform 8 near the tenoning machine, and a sliding track corresponding to the sliding base is provided on the tenoning machine. Under the action of the lifting platform cylinder 9, the worktable 8 is driven to move up and down along the sliding track. Limiting components are provided on both the left and right sides of the worktable 8. The limiting components include limiting plates 5 vertically mounted on the worktable 8. The outer side of the limiting plate 5 is connected to the limiting screw seat 7 through a limiting connecting plate 10. The limiting screw seat 7 is screwed to the limiting screw 6. The limiting screw 6 is rotatably mounted on the bottom of the worktable 8. By rotating the limiting screw 6, the limiting screw seat 7 moves on the limiting screw 6, thereby allowing the two limiting plates 5 to move on the worktable, facilitating the limiting of plates of different widths. A limiting locking bolt 12 is provided at the upper end of the limiting connecting plate 10. When the limit plate 5 is adjusted to the appropriate position, the limit locking bolt 12 rotates on the limit connecting plate 10, so that the limit locking bolt 12 abuts against the worktable 8 to prevent the limit screw from being accidentally touched and causing the limit plate 5 to shift.

[0022] The lifting platform 8 is equipped with a pressing assembly, which includes a pressing support frame 15 installed on the upper end of the worktable 8. A pressing cylinder 1 is located at the upper end of the pressing support frame 15, and the pressing cylinder 1 is connected to a pressing plate 14. The pressing plate 14 moves vertically under the action of the pressing cylinder. The pressing plate 14 prevents displacement of the board material during tenoning, ensuring accuracy.

[0023] The tenoning device includes a tenoning assembly and a positioning assembly located on the upper end of the tenoning assembly. The tenoning assembly includes a tenoning box 13 and a detachable tenoning knife assembly 4 installed inside the tenoning box 13, which can be easily replaced when worn. The tenoning box 13 is connected to a blower 17 via a connecting pipe. The blower 17 removes wood chips and other dust generated during the tenoning process, preventing pollution to the working environment and ensuring environmental hygiene.

[0024] The positioning assembly includes a positioning seat 2 slidably mounted on the upper end of the tenoning assembly under the action of a positioning drive unit. The front end of the positioning seat 2 is connected to a positioning block 3, which is positioned between the tenoning assembly and the pressing assembly. The positioning drive unit includes a positioning screw 18 rotatably mounted on the upper end of the tenoning box 13. A positioning screw seat 19 is screwed onto the positioning screw 18 and is connected to the positioning seat 2. By rotating the positioning screw 18, the positioning screw seat 19 rotates on the positioning screw 18, thereby causing the positioning screw seat 19 to drive the positioning block 2 to move laterally, thus accurately setting the tenon depth. The positioning seat 2 is provided with a positioning locking bolt 16. After adjusting the position of the positioning block 3, tightening the positioning locking bolt 16 can prevent accidental contact with the positioning screw, which could cause a deviation in the tenon depth.

[0025] In use, the limiting plate and positioning block are first adjusted to the appropriate positions, the worktable is raised to the positioning block, and then the board is placed on the worktable. The front end of the board abuts against the positioning block, the left and right ends of the board are limited by the limiting plate, and the upper end of the board is pressed by the pressure plate. Then, the worktable is driven by the lifting cylinder to the tenoning point of the tenoning machine. The generated wood chips are transferred by the blower. After the tenoning is completed, the worktable rises and the pressure plate moves up. The worker takes out the board that has been tenoned and places a new board that needs to be tenoned. This process is repeated until all boards have been tenoned.

[0026] This invention features an adjustable limiting plate for easy positioning of boards of different widths, an adjustable positioning block for accurate setting of tenon depth, and a pressing component to press the board firmly, preventing the wood from shifting during tenoning, thus improving accuracy and reducing labor and material waste. Additionally, the invention includes a blower to remove sawdust and dust generated during processing, preventing pollution of the working environment and promoting environmental hygiene.
