Description

Technical Field

[0001] The utility model relates to the technical field of plate cutting, and more particularly to a positioning mechanism for a plate cutting machine. Background Art

[0002] During mechanical processing, common methods for cutting sheet metal include manual cutting, cutting with semi-automatic cutting machines, and cutting with CNC cutting machines. Manual cutting is flexible and convenient, but it suffers from poor cutting quality, large dimensional errors, significant material waste, and a high subsequent processing workload. Furthermore, the working conditions are harsh and production efficiency is low. Among semi-automatic cutting machines, contour cutting machines offer better workpiece quality, but because they use cutting dies, they are not suitable for cutting single pieces, small batches, or large workpieces. While other types of semi-automatic cutting machines reduce labor intensity, their functionality is simple and they are only suitable for cutting parts with more regular shapes. Compared to manual and semi-automatic cutting methods, CNC cutting can effectively improve sheet metal cutting efficiency and quality, while reducing operator labor intensity.

[0003] At present, in the process of cutting wooden boards, it is sometimes necessary to cut the entire wooden board into equal-distance sections. The traditional cutting method requires manual equal-distance marking on the surface of the wooden board, and cutting based on the cutting line. After the front cutting is completed, the position of the wooden board needs to be repeatedly adjusted to align the cutting line, and the positioning mechanism is used to position the adjusted wooden board before the next cutting process can be carried out. This is not conducive to improving processing efficiency. In view of this, we propose a positioning mechanism for a board cutting machine. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to actual needs, and provide a positioning mechanism for a board cutting machine to solve the technical problem that the current traditional cutting method requires manual equidistant marking on the surface of the wooden board, which is not convenient for improving processing efficiency.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a plate cutting machine positioning mechanism, comprising a receiving assembly symmetrically and movably provided with a feeding assembly inside;

[0006] The receiving assembly includes a mounting panel with a supporting plate fixedly mounted on one side, a wooden board placed on the surface of the mounting panel, and a limit block symmetrically fixedly mounted on one side of the mounting panel, wherein a limit hole is formed inside the limit block;

[0007] The feed assembly includes a rotating shaft rotatably mounted in the mounting panel, an eccentric block being eccentrically fixedly mounted on the outer edge surface of the rotating shaft, a bearing being provided on the outer edge surface of the eccentric block, a feed ring being provided on the outer edge surface of the bearing, a cutting assembly for cutting the wooden board being fixedly provided on one side of the outer edge surface of the feed ring, and a U-shaped slide being fixedly mounted on the other side of the outer edge surface of the feed ring, a flat portion being formed at the bottom of the outer edge surface of the feed ring, a limiting structure being slidably connected to a limiting hole being movably mounted in the U-shaped slide, one end of the rotating shaft extending through the back of the mounting panel and fixedly connected to a driven structure;

[0008] A driving assembly for cooperating with a driven structure and driving the rotating shaft to rotate is detachably mounted on the top of the receiving assembly.

[0009] The utility model designs a rotating shaft, an eccentric block, a cutting assembly, a driven structure, a limiting structure and a driving assembly. The driving assembly drives the rotating shaft to rotate. Since the rotating shaft and the eccentric block are eccentrically arranged, the rotating shaft will drive the feed ring to reciprocate and feed the wooden board at equal intervals when rotating, thereby realizing equal-distance cutting of the wooden board through the cutting assembly and realizing continuous cutting of the wooden board at the same time, without the need for manual marking on the wooden board, which is beneficial to improving the efficiency of equal-distance cutting of the wooden board, and the reciprocating grabbing and pushing of the wooden board by the feed ring is beneficial to reducing the dimensional error of the equal-distance cutting, thereby improving the cutting accuracy of the wooden board.

[0010] Preferably, the limiting structure includes a sliding shaft movably installed in a U-shaped sliding seat, and both ends of the sliding shaft are connected to a limiting plate, and a limiting rod movably inserted in a limiting hole is fixedly installed in the center of one side of one of the limiting plates.

[0011] Preferably, the driven structure includes a driven wheel fixedly mounted on the outer edge surface of the end of the rotating shaft, and a gear is fixedly mounted on the outer edge surface of one end of the rotating shaft extending through the back of the mounting panel, and the gears in the symmetrically arranged feed assembly are meshed with each other.

[0012] Preferably, the mounting panel is provided with a support plate on one side of the top structure to form a support plate, the driving assembly includes a second motor detachably mounted on the support plate, a driving wheel is fixedly mounted on the end of the shaft of the second motor, and a transmission belt is connected between the driving wheel and the driven wheel.

[0013] Preferably, the cutting assembly includes a connecting block arranged on the outer edge surface of the feed ring, and one end of the connecting block away from the feed ring is fixedly connected to a U-shaped tool holder.

[0014] Preferably, a motor 1 is detachably mounted on one side of the U-shaped tool holder, and the motor 1 is connected to a cutting disc rotatably mounted in the U-shaped tool holder via a motor shaft.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model designs a rotating shaft, an eccentric block, a cutting assembly, a driven structure, a limiting structure and a driving assembly. The driving assembly drives the rotating shaft to rotate. Since the rotating shaft and the eccentric block are eccentrically arranged, the rotating shaft will drive the feed ring to reciprocate and grab the wooden board and feed it at equal intervals when rotating, thereby realizing equal-distance cutting of the wooden board through the cutting assembly and realizing continuous cutting of the wooden board at the same time. There is no need for manual marking on the wooden board, which is beneficial to improving the efficiency of equal-distance cutting of the wooden board. The reciprocating grabbing and pushing of the wooden board by the feed ring is beneficial to reducing the dimensional error of the equal-distance cutting, thereby improving the cutting accuracy of the wooden board, and solving the problem that the traditional cutting method requires manual equal-distance marking on the surface of the wooden board, which is not convenient for improving processing efficiency.

[0017] 2. The utility model also forms a flat portion at the bottom of the outer edge of the feed ring. When the feed ring grabs the wooden board, the flat portion abuts against the surface of the wooden board. Its flat structure is conducive to increasing the contact area with the surface of the wooden board, thereby improving the stability of grabbing and feeding the wooden board.

A flat portion 315 is formed at the bottom of the outer edge surface of the feed ring 304, and a limiting structure that is slidably connected to the limiting hole 105 is movably installed in the U-shaped slide 311. One end of the rotating shaft 301 extends through the back of the mounting panel 101 and is fixedly connected to the driven structure. The top of the receiving component 1 is detachably installed with a driving component 4 for cooperating with the driven structure and driving the rotating shaft 301 to rotate.

[0027] In an embodiment of the present utility model, the limiting structure includes a sliding shaft 312 movably installed in a U-shaped slide 311, and both ends of the sliding shaft 312 are connected to a limiting plate 313. A limiting rod 314 movably inserted into the limiting hole 105 is fixedly installed in the center of one side of one limiting plate 313.

[0028] In an embodiment of the present utility model, the driven structure includes a driven wheel 306 fixedly mounted on the outer edge surface of the end of the rotating shaft 301, and the rotating shaft 301 extends through the outer edge surface of one end of the back of the mounting panel 101 and is fixedly mounted with a gear 305. The gears 305 in the symmetrically arranged feed assembly 3 are engaged with each other. The mounting panel 101 is provided with a support plate 102 and the top structure thereof is formed with a support plate 103. The driving assembly 4 includes a motor 2 401 detachably mounted on the support plate 103. A driving wheel 402 is fixedly mounted on the end of the shaft of the motor 2 401, and a transmission belt 403 is connected between the driving wheel 402 and the driven wheel 306.

[0029] In an embodiment of the present invention, the cutting assembly includes a connecting block 307 constructed on the outer edge surface of the feed ring 304, and the end of the connecting block 307 away from the feed ring 304 is fixedly connected to a U-shaped tool holder 308, and a motor 309 is detachably installed on one side of the U-shaped tool holder 308.

[0030] Working principle: This embodiment provides a plate cutting machine positioning mechanism. When in use, first place the wood board 2 to be cut on the supporting plate 102, then start the motor 1 309 to rotate the cutting disc 310, and start the motor 2 401 to rotate the driving wheel 402, thereby driving the driven wheel 306 to rotate through the transmission belt 403, so that the rotating shaft 301 rotates. When the rotating shaft 301 rotates, it drives the eccentric block 302 to rotate eccentrically. At the same time, the rotation of the feed ring 304 is limited by the movable plug-in cooperation of the limiting rod 314 and the limiting hole 105, so that the feed ring 304 is centered on the axis of the rotating shaft 301. Eccentric movement is performed, so that the feed ring 304 reciprocates to grab the wooden board 2 and feeds it at equal intervals. During the feeding process, since the cutting assembly is fixed to the feed ring 304, the cutting assembly follows the eccentric movement of the feed ring 304. During the feeding process, the cutting disk 310 gradually contacts the wooden board 2 and realizes the slitting processing of the wooden board 2. By forming a flat portion 315 at the bottom of the outer edge surface of the feed ring 304, during the process of the feed ring 304 grabbing the wooden board 2, the flat portion 315 abuts against the surface of the wooden board 2. Its flat structure is conducive to increasing the contact area with the surface of the wooden board 2, thereby improving the stability of grabbing and feeding the wooden board 2.

Ordinary technicians in this field can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes.
