Description

Technical Field

[0001] The invention belongs to the technical field of bamboo weaving, and in particular relates to a punching machine with adjustable tilt angle. Background Art

[0002] Bamboo weaving is a handicraft that is deeply loved by consumers. Most of the weaving is done by hand, and the woven products have different shapes and are uneven. In particular, after the bamboo strips are made into a ring, inclined holes are punched on the ring-shaped bamboo strips. In the existing technology, a hand-held electric drill is used to punch the inclined holes on the ring-shaped bamboo strips, resulting in inconsistent tilt angles, inconvenient processing, and poor product quality. Summary of the Invention

[0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a punching machine with an adjustable tilt angle, which has consistent punched holes, is easy to process, has good product quality, and can adjust the tilt angle. The punching machine can also be used for punching circular holes in wood.

[0006] The rotating arms A and B rotate around the connecting head B which is penetrated by the bolt.

[0007] The two ends of the pin are clamped in the sliding grooves provided at the lower end of the shaft A and can slide up and down.

[0008] The rotating arm B is arc-shaped and is provided with an arc-shaped through hole.

[0009] The threads of the studs A and B are respectively forward and reverse threads, and the threads of the studs D and C are respectively forward and reverse threads.

[0010] The threads provided at both ends of the screw sleeve B and the screw sleeve C are respectively forward and reverse threads.

[0011] The shaft A inserted into the rotating sleeve A is rotatable.

[0012] The shaft B can rotate within the rotating sleeve B.

[0013] The lower end of the shaft B is covered with a positioning seat cover, and the positioning cover is screwed into the positioning bolt for connection.

[0014] The rotating sleeve B and the positioning cover can rotate along with the shaft B.

[0015] Compared with the prior art, the present invention has obvious advantages and beneficial effects. It can be seen from the above technical scheme that the present invention fixes one end of stud B, one end of stud C and a bracket on both sides of the rotating sleeve B, the other end of stud B and the other end of stud C are respectively screwed into one end of screw sleeve B and one end of screw sleeve C, the other end of screw sleeve B and the other end of screw sleeve C are respectively screwed into one end of stud A and one end of stud D, the other end of stud A and the other end of stud D are respectively fixedly connected to one end of connector A and one end of connector B, the other end of connector A and the other end of connector B are respectively penetrated with bolts to connect one end of rotating arm A and one end of rotating arm B, the other end of rotating arm A and the other end of rotating arm B are respectively fixedly connected to screw sleeve A and rotating sleeve A, shaft A is inserted into rotating sleeve A, the upper end of shaft A is inserted into the hole set at the lower end of turntable and the upper end of screw shaft is inserted into the pin for connection, the thread set at the lower end of screw shaft is screwed into screw sleeve A and passed out, and the lower end of screw shaft is connected to the drill bit. By rotating screw sleeves B and C, studs A, B, D, and C are retracted and expanded to the left and right, respectively. This in turn drives rotating arms A and B, centered around the bolt inserted into connector B, to adjust the drill bit's tilt angle at the lower end of the screw shaft. This ensures consistent hole tilt angles. A rotating sleeve B is mounted in the middle of shaft B, and its lower end is covered with a positioning cap, which is then screwed into place with a positioning bolt. A circular bamboo strip is placed over rotating sleeve B from below. The positioning bolt is then fitted with a positioning cap, which is pressed under the strip and screwed into shaft B. After drilling one tilted hole, rotating sleeve B, the positioning cap, and circular bamboo strip are rotated to drill the next hole, ensuring convenient processing and high-quality products.
