TECHNICAL FIELD

[0001] The utility model belongs to the field of punching device, concretely relates to a willow wood punching device. BACKGROUND

[0002] Willow wood products refer to various practical or decorative articles made of willow wood as the main material through processing and manufacturing. Such products usually have natural beauty, unique texture and practicality, such as furniture, tools, ornaments, etc.

[0003] The processing technology of willow wood products includes punching, cutting, carving, weaving, splicing and other techniques. Among them, it may involve punching of relatively thick willow wood plates, and when the diameter of the punch hole is large, it may not be punched through at one time, and then the plate needs to be turned over for secondary punching. In the secondary punching process, punching deviation may occur, making the hole of the first punching not aligned. INVENTION CONTENTS

[0004] In view of the deficiencies of the prior art, the purpose of the utility model is to provide a willow wood punching device, which solves the problem that when punching a relatively thick plate and the diameter of the punch hole is large, the plate cannot be punched through at one time using a large-diameter drill, and then the plate needs to be turned over for secondary punching. In the secondary punching process, punching deviation may occur, making the hole of the first punching not aligned.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] A willow wood punching device, comprising:

[0007] A first guide rail, a first sliding groove is formed in the first guide rail, a first bidirectional screw is rotatably connected in the first sliding groove, a first sliding block that slides in the first sliding groove is threadedly connected to the threads of the first bidirectional screw in two different directions, and a transmission shaft is rotatably connected between the two ends of the first guide rail;

[0008] A fixed frame is fixedly connected with the first sliding block, a second rotating shaft is rotatably connected in the fixed frame, a first bevel gear and a second bevel gear are fixedly connected to the two ends of the second rotating shaft, a third bevel gear is engaged with the side of the first bevel gear, a shaft sleeve is fixedly connected to the third bevel gear, the shaft sleeve is rotatably connected with the fixed frame, the two shaft sleeves are slidably sleeved on the transmission shaft, a fourth bevel gear is engaged with the side of the second bevel gear, a third rotating shaft is fixedly connected to the fourth bevel gear, and the third rotating shaft is rotatably connected with the fixed frame;

[0009] The second guide rail is fixedly connected to the third rotating shaft. The second guide rail has a second sliding groove. A lead screw is rotatably connected in the second sliding groove. A second slider is threadedly connected to the lead screw and slides in the second sliding groove. A fixed frame is fixedly connected to the second slider. A first motor is fixedly connected in the fixed frame. A milling cutter is fixedly connected to the output end of the first motor.

[0010] The principles and technical effects of the above technical solution are as follows:

[0011] A thicker willow board is horizontally placed and fixed between two milling cutters. To determine the required hole radius, a drive screw rotates, moving a second slider so that the distance between the milling cutter and the third shaft axis matches the required hole radius. The two milling cutters are staggered to prevent collisions. A first bidirectional screw rotates, bringing the two first sliders closer together, which in turn brings the two fixed frames closer together, causing the two milling cutters to approach and contact the board. A first motor drives the milling cutters to mill the board. A drive shaft rotates, and through the transmission of the third, first, second, and fourth bevel gears and the third shaft, the second guide rail rotates around the third shaft, which is located in the center of the second guide rail. The rotation of the second guide rail causes the milling cutter to rotate around the third shaft, performing circular milling. During milling, the first bidirectional screw is slowly rotated, allowing the two milling cutters to advance and mill simultaneously, staggered vertically, on the thicker willow board. This method prevents misalignment of the milled holes and improves drilling efficiency.

[0012] In a preferred embodiment, the present invention can be further configured such that a base is fixedly connected to the bottom of the first guide rail.

[0013] In a preferred embodiment, the present invention can be further configured as follows: a third guide rail is provided on both sides of the milling cutter, a third slide groove is provided on the third guide rail, a second bidirectional lead screw is rotatably connected in the third slide groove, and a clamping plate that slides in the third slide groove is threadedly connected to the two threads of the second bidirectional lead screw with different directions of rotation, and a telescopic cylinder is fixedly connected to the lower end of the third guide rail, and the lower end of the telescopic cylinder is fixedly connected to the base.

[0015] In a preferred embodiment, the present invention can be further configured such that: a second motor is fixedly connected to the upper end of the first guide rail, and the output end of the second motor is fixedly connected to the end of the first bidirectional lead screw.

[0016] The utility model discloses in a preferable example can be further configured as: the upper end fixed connection of first guide rail has third motor, the output of third motor and the end of transmission shaft fixed connection.

[0019] The following explains the nouns, conjunctions or adjective parts involved in the above technical solutions:

[0020] Fixed connection refers to the connection of parts or components after being fixed, without any relative movement. Among them, it is divided into two kinds of detachable connection and non-detachable connection.

[0021] (1) detachable connection is to fix the parts together by using screw, spline, wedge pin, etc. This connection mode can be disassembled during maintenance, and the parts will not be damaged. But the specifications of the connecting parts used must be correct (such as the length of bolt, key, wedge pin), and be fastened properly.

[0022] (2) non-detachable connection mainly refers to welding, riveting and over mortise cooperation, etc. Because maintenance or replacement needs to be forged, sawed or oxygen cut to disassemble, so the parts generally cannot be used twice. At the same time, attention should be paid to the process quality, technical detection and remedial measures (such as correction, polishing, etc.) during connection.

[0023] Threaded connection refers to the detachable connection of connecting parts by using threaded parts (or threaded parts of connected parts).

[0024] Sliding connection refers to the contact between two objects, but not fixed, and the two can slide relative to each other.
