Embodiment 1

[0052] Such as figure 1 As shown, the planar two-dimensional mobile workbench includes an axial movement platform 21 and a lateral movement platform 22, the axial movement platform 21 driven by a ball screw is arranged on the base 1 through bolt connection, and the movement platform 21 driven by a ball screw The lateral movement platform 22 is arranged on the axial movement platform 21 through bolt connection, and the constraining frame 3 is arranged on the transverse movement platform 22 through bolt connection, and through the cooperating drive of the axial movement platform 21 and the transverse movement platform 22, the constraint frame 3 drives the The processing of wood 10 realizes arbitrary track movement in the composite two-dimensional plane of transverse and axial directions.

[0053] Continue to see figure 1 , the poplar hollow bar production part includes a low-frequency pulse power supply 11, a low-frequency piezoelectric non-resonant vibrator 13 connected to the...

Embodiment 2

[0073] The difference from Embodiment 1 is that the tool arrangement plate 152 also includes a cover 1523 for the internally threaded hole 1522 . It is used for the closure of the internally threaded hole 1522 not connected to the knife tube.

[0074] For example, when the diameter of the hollow bar body of the preprocessed wood is large, such as Figure 8 As shown, the external thread head 1533 of the knife tube matches the internal thread hole 1522, and the cavity 153 matches the size of the pre-machined hole.

[0075] Since the outer diameter of the knife tube becomes larger, it is impossible to sequentially arrange the knife tubes on the knife arrangement plate 152 , and the unused internal threaded hole 1522 is closed by the cover 1523 .

[0076] Using the processing process described in Embodiment 1, the processing of multiple cylindrical hollow strip blanks 23 can be realized.

Abstract

The invention relates to a poplar hollow strip mass manufacturing device and application thereof. A workbench comprises a base table, a plane two-dimension moving workbench, a constraint frame, an up-and-down moving platform, a retaining bracket and a poplar hollow strip manufacturing component. The poplar hollow strip manufacturing component comprises a low-frequency impulse power source, a low-frequency piezoelectricity non-resonant vibrator, an amplitude amplifier and a compound tool. The compound tool comprises a coupler, a tool laying plate, multiple cutting pipes and multiple circinate blades, wherein the coupler, the tool laying plate, the multiple cutting pipes and the multiple circinate blades. On end of each cutting pipe is connected with the tool laying plate in a detachable manner. The other end of each cutting pipe extends to be the corresponding circinate blade. A shaft-circumference compound vibration switching structure is arranged on each cutting pipe. According to thepoplar hollow strip mass manufacturing device and application thereof, by means of high-frequency resonance, a poplar hollow strip can be mass manufactured on wood. A workpiece can move along any track on the two-dimension plane through the plane two-dimension moving workbench; up-and-down precise movement can be achieved through the poplar hollow strip mass manufacturing device; mass manufacturing of multiple poplar hollow strips one time is conducted on the to-be-manufactured wood through the retaining bracket.

Description

technical field [0001] The invention belongs to wood processing equipment and its application, in particular to a poplar hollow bar mass production device and its application. Background technique [0002] In the production of handicrafts, poplar hollow bar parts are often needed. At present, this method is mainly used to make poplar hollow bars: first, the inner hole is made by drilling, and then the outer circular contour is made by turning or grinding. However, under the action of the rotating tool, it will be subjected to horizontal and circumferential forces in the axial direction, resulting in multi-directional deformation of the poplar hollow bar. In order to ensure the hole roundness, size and axial levelness of the poplar hollow bar, it must be processed manually. The operation is realized by adjusting the force at any time. Even so, there is a high defective rate, so the processing cost is high, the control is difficult, and the processing efficiency is low. The p...
