Description

Technical Field

[0001] This utility model relates to the field of wood structure processing technology, specifically a tool for tenoning beams and columns in ancient building wood structures. Background Technology

[0002] Ancient buildings refer to a type of civil and public buildings with historical significance. Ancient buildings are mainly timber-framed structures, using wooden columns and beams to form the framework of the house. The weight of the roof and eaves is transferred to the main body of the columns through the beam frame, and a stable framework is formed by mortise and tenon joints. With the development of the tourism industry, major scenic spots have also begun to build ancient buildings. The beams and columns are the key links in the construction of mortise and tenon joints, affecting the overall stability of the timber structure and the service life of the building.

[0003] Traditional manual tenoning tools are difficult to meet the time requirements of large-scale ancient building repair or construction. Current machine tenoning tools only support the beams and columns with the length of the machine itself. The tenoning part of the beam and column is located at one end of the beam and column, and the length of the beam and column itself exceeds the length of the machine. Therefore, during the tenoning process, the tenoning end will be unstable due to the excessive length of the other end of the beam and column, which will affect the quality of the tenoning. Utility Model Content

[0006] Preferably, the diameter of the drive roller is smaller than that of the driven rollers on both sides, the two driven rollers have the same diameter, one end of the drive roller is fixedly mounted on the output end of the motor, the motor is embedded and fixed on the surface of the base, the two ends of the drive roller are respectively fixedly mounted with drive gears, the driven rollers are fixedly mounted with driven gears on the surface of the shafts, and the driven gears on the surfaces of the two driven rollers mesh with the drive gears from both sides.

[0007] By adopting the above technical solution, the driven rollers on both sides are driven to rotate synchronously by the rotating drive roller, thereby realizing the automatic feeding and discharging process of beams and columns.

[0008] Preferably, the base has an internal support structure, which synchronously drives the support block to slide outward through the driven gear at the feeding structure to support the beam and column.

A rack is fixedly connected to one side surface of the support block, and the rack meshes with one set of driven gears.

[0011] By adopting the above technical solution, the sliding process of the support block can be realized by utilizing the meshing between the rack and the driven gear.

[0012] Preferably, the upper surface of the base is provided with a locking structure, which uses moving locking blocks to clamp the beam and column, facilitating tenoning operations.

[0013] Using the above technical solution, the beams and columns can be clamped together by means of a locking structure.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a tenoning tool for wooden beams and columns of ancient buildings, including a base 1, a support plate 1, a drill bit 3, a drive roller 4, a driven roller 5, a motor 6, a drive gear 7, a driven gear 8, a support block 9, a rack 10, a support plate 2 11, an electric push rod 12, a connecting plate 13, a locking block 14, and a telescopic rod 15.

[0031] The base 1 is a cuboid structure. A rectangular groove is provided on the upper surface of the base 1. The interior of the base 1 is hollow. Two support plates 2 are symmetrically arranged on one side surface of the base 1. A drill bit 3 is installed between the two support plates 2, and the drill bit 3 is connected to a CNC mechanism. A feeding structure is provided within the groove on the surface of the base 1. The feeding structure facilitates the feeding process of the tenoned beam / column through a rotating drive roller 4 and a driven roller 5. The feeding structure includes a drive roller 4, whose two ends are rotatably mounted on the inner wall of the groove on the surface of the base 1. Two driven rollers 5 are respectively provided on both sides. The two driven rollers 5 are rotatably installed on the inner wall of the groove on the surface of the base 1. The diameter of the drive roller 4 is smaller than that of the two driven rollers 5. The two driven rollers 5 have the same diameter. One end of the drive roller 4 is fixedly installed on the output end of the motor 6. The motor 6 is embedded and fixed on the surface of the base 1. The two ends of the drive roller 4 are respectively fixedly installed with drive gears 7. The driven rollers 5 are fixedly installed with driven gears 8 on the surface of the shaft. The driven gears 8 on the surface of the two driven rollers 5 mesh with the drive gears 7 from both sides.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, when using this device, the motor 6 is started, and the motor 6 drives the drive roller 4 to rotate counterclockwise. The drive roller 4 drives the drive gear 7 on the surface to rotate counterclockwise. The drive gear 7 drives the driven gears 8 on both sides to rotate clockwise. The driven gears 8 drive the driven roller 5 to rotate clockwise. The beam is placed on the upper surface of the base 1, so that the surface of the beam contacts the surface of the driven roller 5. Under the action of the rotating driven roller 5, it moves towards the drill bit 3 for feeding. The drill bit 3 performs tenoning operation on the beam under the control of the CNC mechanism. After the tenoning is completed, the motor 6 is started to rotate in the opposite direction, and the driven roller 5 rotates in the opposite direction to send out the processed beam.

[0033] The base 1 has an internal support structure. The support structure drives the support block 9 to slide outward synchronously through the driven gear 8 set at the feeding structure to support the beam and column. The support structure includes the support block 9, which has an inverted n-shaped cross section. The lower surface of the support block 9 is slidably connected to the inside of the base 1, and the support block 9 slides through one side surface of the base 1. The upper surface of the support block 9 is flush with the upper surface of the base 1. A rack 10 is fixedly connected to one side surface of the support block 9, and the rack 10 meshes with one set of driven gears 8.

[0034] like Figure 3 , Figure 4 and Figure 5 As shown, when the driven roller 5 rotates clockwise to feed the beam and column, the driven gear 8 rotates clockwise, driving the rack 10 to move to the left. When the rack 10 moves to the left, it will drive the support block 9 to slide to the left in sync. The support block 9 slides to the left to support the other end of the beam and column, preventing displacement during the tenoning process due to the excessive length of the beam and column, and increasing the stability of the tenoning process.

[0035] The upper surface of the base 1 is provided with a locking structure. The locking structure clamps the beam and column through the moving locking block 14, which facilitates the tenoning operation. The locking structure includes a second support plate 11, which is fixedly installed on the upper surface of the base 1. An electric push rod 12 is fixedly installed on the surface of the second support plate 11. A connecting plate 13 is fixedly installed at the output end of the electric push rod 12. A connecting rod with a telescopic structure is provided on the surface of the connecting plate 13 and connected to the second support plate 11. A locking block 14 is provided on the side surface of the connecting plate 13. The cross-section of the locking block 14 is a semi-circular arc block structure. The lower end of the locking block 14 is rotatably connected to the surface of the connecting plate 13. A telescopic rod 15 is connected to the upper end of the locking block 14. The other end of the telescopic rod 15 is slidably installed on the surface of the connecting plate 13. Two second support plates 11 are symmetrically arranged, and the surface structures of the two second support plates 11 are the same.

[0036] like Figure 1 and Figure 6 As shown, before the beam and column are tenoned, the electric push rods 12 on both sides are activated. The electric push rods 12 drive the connecting plate 13 to move. The connecting plate 13 drives the locking blocks 14 on its surface to approach the beam and column surface. Since the lower end of the locking block 14 is rotatably connected to the surface of the connecting plate 13, the locking block 14 is in an inclined state when it contacts the beam and column, with its lower end in contact with the beam and column. As the locking block 14 continues to move, the upper ends of the locking blocks 14 on both sides compress the telescopic rods 15 and clamp the beam and column surface to the surface of the locking blocks 14 on both sides, so as to prevent the beam and column from shifting during the tenoning process.

[0037] Working principle: When using this ancient building wooden beam and column tenoning tool, the motor 6 is started, which drives the drive roller 4 to rotate. The drive roller 4 drives the drive gear 7 to rotate, and the rotating drive gear 7 drives the driven gear 8 to rotate, thereby driving the driven roller 5 to rotate, and automatically feeding the beam and column. When the driven gear 8 rotates, it drives the rack 10 to move, and the support block 9 slides to the left to support the other end of the beam and column, preventing displacement during the tenoning process due to the excessive length of the beam and column, and increasing the stability of the tenoning process. The electric push rod 12 is started, which drives the connecting plate 13 to move. The connecting plate 13 drives the locking block 14 to lock the beam and column, preventing the beam and column from shifting during the tenoning process, and increasing the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
