Description

一种适用于竹材剖分的交替式自动换刀机构An Alternate Automatic Tool Changing Mechanism for Bamboo Splitting

技术领域technical field

本发明创造属于林业机械,主要涉及一种交替式自动换刀机构,适用于各类具有自动测量竹材几何形状功能的全自动剖竹机。The invention belongs to forestry machinery, and mainly relates to an alternate automatic tool changing mechanism, which is suitable for all kinds of automatic bamboo cutting machines with the function of automatically measuring the geometric shape of bamboo materials.

背景技术Background technique

竹材剖分过程中需根据竹材的几何特征,选用能把竹材剖分为不同份数的刀具,以使剖分后的竹条宽度相近。因此,能够根据竹材几何特征进行自动换刀的全自动剖竹机应运而生。目前的全自动剖竹机主要存在两类问题,第一,由于目前所使用的剖竹机大多将多个刀具布置在一个大型圆盘上,通过圆盘的旋转与停止实现换刀,造成体积过于庞大;第二,这类将多个刀具布置在一个大型圆盘上,通过圆盘的旋转与停止实现换刀的机构受到机械系统限制,换刀时消耗的时间过长,严重掣肘了加工效率,影响了后续加工的进行。因此,设计一种通过两组刀具交替式工作的换刀机构,使设备中的换刀机构体积有所减小,降低设备对场地的要求,使设备便于运输;且作业过程中针对不同直径的竹材进行换刀时,能够大幅减少换刀的时间,提升设备的整体加工效率,具有一定的实际意义。In the process of bamboo splitting, according to the geometric characteristics of the bamboo, a tool that can split the bamboo into different parts should be selected, so that the width of the split bamboo strips is similar. Therefore, the fully automatic bamboo cutting machine that can automatically change the knife according to the geometric characteristics of the bamboo material came into being. There are mainly two types of problems in the current automatic bamboo cutting machine. First, most of the bamboo cutting machines currently used arrange multiple cutters on a large disc, and the cutter is changed by the rotation and stop of the disc. It is too bulky; second, this type of mechanism that arranges multiple tools on a large disc, and realizes tool change through the rotation and stop of the disc is limited by the mechanical system, which takes too long to change the tool, which seriously hinders the processing. efficiency, which affects the subsequent processing. Therefore, a tool change mechanism is designed that works alternately through two sets of tools, so that the volume of the tool change mechanism in the equipment is reduced, the requirements of the equipment on the site are reduced, and the equipment is easy to transport; When changing the tool for bamboo, it can greatly reduce the time of changing the tool and improve the overall processing efficiency of the equipment, which has certain practical significance.

发明内容SUMMARY OF THE INVENTION

本发明创造的目的就是针对上述现有技术存在的问题,针对全自动剖竹机,研究设计一种由两组刀具组成的交替式工作的自动换刀机构。通过将传统自动剖竹机换刀机构中刀具的圆盘式布置改为两组由多个刀具纵向排列组成的刀具组,配合可横向移动的刀具抽取装置,实现刀具的快速更换。The purpose of the present invention is to study and design an automatic tool changing mechanism composed of two sets of cutting tools, which is composed of two sets of cutting tools. By changing the disc-type arrangement of the knives in the knife-changing mechanism of the traditional automatic bamboo cutting machine into two sets of knives consisting of multiple knives arranged longitudinally, and cooperating with the laterally movable knives extracting device, the rapid replacement of knives is realized.

本发明创造的目的是这样实现的:分别将不同型号的刀具固定在带有移动滑轮的刀具架上,并将其依次纵向排列,安装在滑台中的可移动部分,组成两组分别具有能将竹材剖分为5~16份刀具的刀具组;在两组刀具中间安装可横向移动的刀具抽取装置,刀具抽取装置的机架与滑台基座固定。至此构成一种适用于竹材剖分的交替式自动换刀机构。The purpose created by the present invention is achieved in this way: respectively fix different types of tools on tool holders with moving pulleys, arrange them longitudinally in turn, and install the movable parts in the sliding table, forming two groups of The bamboo is divided into 5 to 16 cutter sets; a laterally movable cutter extraction device is installed between the two sets of cutters, and the frame of the cutter extraction device is fixed with the sliding table base. So far, an alternate automatic tool changing mechanism suitable for bamboo splitting is formed.

本发明创造利用滑台中丝杠的正反方向旋转带动刀具组中滑台可移动部分进行直线往复运行,实现刀具组中各个刀具位置的纵向移动,使所需的指定刀具与刀具抽取装置对齐;并通过刀具抽取丝杠的正反旋转,改变刀具抽取装置的位置,使刀具抽取装置能够进行左右移动,以改变左右两侧刀具的位置,刀具抽取装置移动时,使其中一把刀具自剖竹位置退回至刀具组中,同时将另一侧的刀具自刀具组中抽出移动至剖竹位置,最终实现剖竹刀具的快速更换。同时,该自动换刀机构具有结构简单、设计新颖、质量可靠、实用性强的特点。The invention utilizes the forward and reverse rotation of the lead screw in the sliding table to drive the movable part of the sliding table in the cutter group to perform linear reciprocating operation, realizes the longitudinal movement of each cutter position in the cutter group, and aligns the required designated cutter with the cutter extraction device; And through the positive and negative rotation of the tool extracting screw, the position of the tool extracting device is changed, so that the tool extracting device can move left and right to change the positions of the left and right tools. When the tool extracting device moves, one of the tools is self-cutting. The position is returned to the cutter group, and at the same time, the cutter on the other side is pulled out of the cutter group and moved to the bamboo cutting position, finally realizing the rapid replacement of the bamboo cutting cutter. At the same time, the automatic tool changing mechanism has the characteristics of simple structure, novel design, reliable quality and strong practicability.
