Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings:

Example 1:

Referring to Figures 1, 2, and 18, the multifunctional CNC rough milling machine includes:

The rough cutting mechanism 1 includes two stations, one of which is equipped with a milling cutter 1-1 and a power source for driving the milling cutter 1-1, which is used to cut both sides of a rod-shaped material for the first time, and the other station is equipped with The jumping knife 1-2 that can be raised and lowered freely and the power source for driving the jumping knife 1-2 are located downstream of the station equipped with the milling cutter 1-1. The jumping knife 1-2 is used to cut the upper and lower sides of the rod-shaped material ;as well as

The thickness cutting mechanism 2 includes at least two stations, each station is equipped with at least one flat knife 2-1 and a power source for driving the flat knife 2-1, and the two adjacent flat knives 2-1 are respectively used for Cutting the top and bottom of rod-shaped material; and

The width cutting mechanism 3 includes at least one station, each station is equipped with two vertical knives 3-1 and a power source for driving the vertical knives 3-1, and the two vertical knives 3-1 are used for cutting rod-shaped materials. left and right sides.

Through rough cutting mechanism 1, thickness cutting mechanism 2, and width cutting mechanism 3, rod-shaped materials are processed to obtain rod-shaped materials of various styles. Style 1: all four sides are flat, style 2: upper and lower are inclined planes, left , The right side is a plane, style 3: the upper and lower sides are planes, the left and right sides are inclined planes, style 4: all four sides are inclined planes, it is specially pointed out that this CNC rough milling machine is equipped with a positioning probe, the width and thickness values read by the positioning probe It is the value set by the worker before the CNC rough milling machine, and the difference value is obtained after comparing the value obtained by projecting the rod-shaped material with the value set before the CNC rough milling machine processing. The difference is the cutting amount to realize automatic measurement. To improve production efficiency, the power source is a three-phase asynchronous motor that drives the cutter shaft for cutting and rotation.

Which jump knife 1-2. This part is used to process the upwardly protruding part on the rod-shaped material, such as bamboo. There are connected and protruding bamboo joints between the bamboo sections. The bamboo joints are the hardest part of the bamboo, and have a large area. Complete removal will cause great damage to the tool, and the tool will often break down. Therefore, rough machining the bamboo joints first, and then use the milling cutter to mill out some of the bamboo joints to reduce the overall area, and remove some of the bamboo joints. The root part is not processed, thereby reducing the strength of the bamboo joint. After entering the thickness cutting mechanism 2, the bamboo joint part is completely cut off, and the cutting wear caused by the two parts of the tool is normal wear, which improves the practical life of the tool. Reduce maintenance.

Each station of the thickness cutting mechanism 2 is equipped with a first motor 2-2, a first eccentric member 2-3 and a first transmission member 2-4 equal in number to the flat knife 2-1. 2-1 are installed on the first eccentric member 2-3 in one-to-one correspondence, and the first motor 2-2 drives the first eccentric member 2-3 through the first transmission member 2-4, and drives the flat Knife 2-1 rotates eccentrically. The flat knife 2-1 of the traditional thickness cutting mechanism 2 is immovable during cutting, and the cutting amount has been set before machining. The surface of the rod-shaped material is a plane without height difference, but in this way, the shape of the rod-shaped material that can be presented is limited. 1. For rod-shaped materials with different cutting thicknesses, it needs to be adjusted manually, so each rod-shaped material needs to be positioned and adjusted once, and the difference must be accurately calculated, which is inefficient and ineffective. , and also increase the use of rod-shaped materials. In order to increase the adaptability of the CNC rough milling machine, it is realized that the flat knife 2-1 in the thickness cutting mechanism 2 can be automatically adjusted. The knife shaft of -1 is rotatably connected to the first eccentric member 2-3, and is driven to rotate by a power source, while the first motor 2-2 drives the first transmission member 2-4 to rotate, and the first transmission member 2-4 drives the rotation of the first transmission member 2-4. The first eccentric member 2-3 rotates, and the rotation of the first eccentric member 2-3 realizes the change of the feed amount of the flat knife 2-1. The first motor 2-2 is a servo motor, which realizes that the flat knife 2-1 can be adjusted according to the cutting surface. In this way, the flat knife 2-1 gradually changes the feed depth according to the height of the plane during cutting, so as to ensure that the cutting amount for the entire section is a floating value instead of unchanged. Set the value to realize the characteristics of multi-style and material saving of rod-shaped materials. After completion, take two rod-shaped materials of the same shape and size, and the two rod-shaped materials have a part with the same angle offset on one side, and assemble the two rod-shaped materials. When a rod-shaped material is used, the two rod-shaped materials can be combined into a rectangular shape, and the feed amount of the tool is adjusted non-one-time linear movement. To ensure that maintenance times are reduced, the first transmission members 2-4 here are respectively the main transmission gear on the first motor 2-2 and the auxiliary transmission gear on the first eccentric member 2-3.

The thickness cutting mechanism 2 is located at the most downstream station equipped with two flat knives 2-1, and the two are respectively used to cut the upper surface of the rod-shaped material. Both the upper and lower sides of the rod-shaped material have parts that need to be cut, and these parts have a certain thickness and connection strength. In the early processing, single flat knife 2-1 of different stations is used, and a flat knife 2-1 of one station is used for cutting. The flat knives 2-1 of the upper and one station are targeted at these parts, so as to avoid the one-time machining in place, avoid the increase of tool wear, and also improve the yield. Therefore, after the preliminary processing is completed, set up a At the cutting station of knife 2-1, the upper and lower sides of the rod-shaped material are synchronously cut at this station, and the thickness of the rod-shaped material can be determined, so that the final thickness after cutting is the same as the rough milling of the CNC before processing. value set on the machine.

The workstation of the width cutting mechanism 3 is equipped with a second motor 3-2, two second eccentric members 3-3, and a second transmission member 3-4, and the two vertical knives 3-1 are respectively installed in two The second eccentric member 3-3, the second motor 3-2 drives the two second eccentric members 3-3 through the second transmission member 3-4, and drives the two vertical knives 3-1 to rotate eccentrically. The use principle of the width cutting mechanism 3 is the same as that of the thickness cutting mechanism 2. The difference is that the processing surfaces are different. The width cutting mechanism 3 is for both sides, while the thickness cutting mechanism 2 is for the upper and lower sides, that is, it will not be repeated here. The second motor 3-2 is also a servo motor, so that the vertical knife 3-1 can automatically change the feed amount according to the change of the cutting surface.

The work station of the width cutting mechanism 3 is also equipped with two distance adjustment pieces 3-5, the rod-shaped material passes through the interval between the two distance adjustment pieces 3-5, and the two distance adjustment pieces 3 -5 is located below the vertical knife 3-1, the second motor 3-2 drives the two second eccentric members 3-4 through the second transmission member 3-4, and the second eccentric members 3-4 Drive the distance adjusting members 3-5 to move inward or outward. The rod-shaped material entering the width cutting mechanism 3 is not a rod-shaped material of equal width, that is, when the rod-shaped material passes through, it is not only necessary to ensure the smooth passage of the rod-shaped material, but also need to be clamped to avoid the rod-shaped material from shifting. Therefore, two distance adjustment pieces 3-5 are set up, so that the distance between the rod-shaped materials can be adjusted, so as to prevent the rod-shaped material from breaking due to the inconsistency with the spacing. Linear bearings are provided at the lower end of each distance adjustment piece 3-5. The slider/slide rail pair, and by installing the cam on the second eccentric member 3-3, the cam abuts on the slider of the linear bearing slider/slide rail pair, through the friction force generated between the cam rotation and the slider Realize the movement of the slider, thereby driving the distance adjustment member 3-5 to move.

The distance adjusting member 3-5 is equipped with a first limiting member 3-5a and a second limiting member 3-5b arranged along the feeding direction and located on both sides of the vertical knife 3-1. The two first limiting members 3-5a on the distance-adjusting member 3-5 are symmetrically arranged, and the two second limiting members 3-5b are symmetrically arranged, and form a rectangular body plane. There is a space between the limiting members 3-5a and between the two second limiting members 3-5b for the rod-shaped material to pass through. The two first stoppers 3-5a and the two second stoppers 3-5b can increase the stress resistance of the rod-shaped material during processing, especially the stress resistance at the cut part, so as to prevent the rod-shaped material from The up and down jumping occurs during cutting to ensure good side cutting effect. At the same time, the first limiting member 3-5a and the second limiting member 3-5b are both plate bodies with the same shape, and the end near the vertical knife has an arc tangent to the blade portion of the vertical knife 3-1. The practice is further optimized to increase the stress resistance of rod-shaped materials during processing.

One of the first limiting members 3-5a is fixed and used as a positioning reference for the rod-shaped material during width processing, and the other first limiting member 3-5a can be outwards according to the overall width of the rod-shaped material. or offset inward. In order to better improve the use effect of the CNC rough milling machine, the two first limiters 3-5a can be adjusted according to the remaining material that slopes outward from the side of the rod-shaped material, and the two first limiters 3-5a One movable, one immovable, and immovable first stopper 3-5a is used as the rod-shaped material positioning reference, that is, one side of the rod-shaped material abuts its inner wall, and the other side has a slanting edge. material, but also against its inner wall, but the first stopper 3-5a against which this part rests moves outward or inward according to the remaining material value, and the movable first stopper 3-5a is provided with The supporting spring 6 against its outer side, the other end of the supporting spring 6 abuts against the positioning plate 7 vertically installed on the outer side wall of the distance adjusting member 3-5, and the positioning plate 7 has an inwardly extending extension plate 8, The extension plate 8 is provided with a chute 8-1. The chute 8-1 has a front end opening 8-1a and a lower end opening 8-1b on the extension plate 8. Both the front end opening 8-1a and the lower end opening 8-1b are used for the first limit. The component 3-5a passes through, so the setting is not only to realize the movement of the first stopper 3-5a, but also there will be no rotation during the movement, because the movement of the first stopper 3-5a is controlled by the supporting spring 6 , after the tension spring 6 itself is affected by the extrusion force, it will bend to the left, right and upward under the condition of no restraint, so the fixed width cannot be achieved, so the chute 8-1 is used as the Constraints, the upper surface of the chute 8-1 is in contact with the upper surface of the first limiting member 3-5a, and the extension plate 8 and the supporting spring 6 are symmetrically arranged on both sides, that is, two positioning points are provided, so that the first The limiter 3-5a has good movement stability and can provide sufficient resistance to rod-shaped materials.
