Description

Automatic tool changing mechanism of alternating suitable for bamboo timber subdivision

Technical Field

The invention belongs to forestry machinery, and mainly relates to an alternating type automatic tool changing mechanism which is suitable for various full-automatic bamboo splitting machines with the function of automatically measuring the geometric shapes of bamboo woods.

Background

In the bamboo splitting process, cutters capable of splitting the bamboo into different parts are selected according to the geometric characteristics of the bamboo, so that the widths of the split bamboo strips are similar. Therefore, a full-automatic bamboo cutting machine capable of automatically changing the tools according to the geometric characteristics of the bamboo materials is produced. Firstly, most of the currently used bamboo splitting machines are provided with a plurality of cutters on a large disc, and the cutters are changed by the rotation and the stop of the disc, so that the volume is too large; secondly, a plurality of cutters are arranged on a large disc, a mechanism for realizing cutter changing through rotation and stop of the disc is limited by a mechanical system, the consumed time for cutter changing is too long, the machining efficiency is seriously stopped, and the subsequent machining is influenced. Therefore, the tool changing mechanism working alternately through two groups of tools is designed, so that the size of the tool changing mechanism in the equipment is reduced, the requirement of the equipment on the field is reduced, and the equipment is convenient to transport; and when the tool changing is carried out on the bamboo woods with different diameters in the operation process, the tool changing time can be greatly reduced, the overall processing efficiency of the equipment is improved, and the tool changing device has certain practical significance.

Disclosure of Invention

The invention aims to solve the problems in the prior art and aims at a full-automatic bamboo splitting machine to research and design an automatic tool changing mechanism which consists of two groups of tools and works alternately. The disc type arrangement of cutters in the cutter changing mechanism of the traditional automatic bamboo cutting machine is changed into two groups of cutter groups formed by longitudinally arranging a plurality of cutters, and the quick replacement of the cutters is realized by matching with a cutter extracting device capable of moving transversely.

The purpose of the invention is realized as follows: the method comprises the following steps of fixing cutters of different types on a cutter frame with a movable pulley respectively, arranging the cutters in sequence longitudinally, and installing the cutters on a movable part in a sliding table to form two groups of cutter groups which can divide bamboo into 5-16 parts of cutters respectively; and a cutter extracting device capable of moving transversely is arranged between the two groups of cutters, and a rack of the cutter extracting device is fixed with the sliding table base. Thus, the alternating type automatic tool changing mechanism suitable for bamboo splitting is formed.

The movable part of the sliding table in the cutter group is driven to linearly reciprocate by utilizing the positive and negative rotation of the screw rod in the sliding table, so that the longitudinal movement of each cutter position in the cutter group is realized, and a required designated cutter is aligned with the cutter extraction device; and through the positive and negative rotation of cutter extraction lead screw, change cutter extraction device's position, make cutter extraction device remove about can moving to the position of change left and right sides cutter, when cutter extraction device moved, make one of them cutter move back to the cutter group from cuing open the bamboo position, draw out the cutter of opposite side from the cutter group simultaneously and move to cuing open the bamboo position, finally realize cuing open the quick replacement of bamboo cutter. Meanwhile, the automatic tool changing mechanism has the characteristics of simple structure, novel design, reliable quality and strong practicability.

Detailed Description

The embodiments of the invention will be described in detail below with reference to the accompanying drawings:

24 cutters 12 on the left side and the right side are longitudinally arranged through a cutter frame 7 with a movable pulley 8 and are installed on a sliding table moving seat 6, the movable pulley 8 in the cutter frame 7 is matched with a cutter replacing guide rail 5, so that the cutter frame 7 can move along the cutter replacing guide rail 5 at a specified position, the sliding table moving seat 6 is installed on a sliding table base 4 through a sliding guide rail 3, meanwhile, the sliding table moving seat 6 is connected with a cutter longitudinal moving motor 1 through a sliding table lead screw 2, and the sliding table moving seat 6 can move back and forth through the rotation of the cutter longitudinal moving motor 1. The cutter extracting device 10 is connected with the cutter extracting motor 9 through a cutter extracting lead screw 11, so that the cutter extracting motor 9 can rotate to move left and right, and the alternating type automatic cutter changing mechanism is fixedly installed with the full-automatic bamboo splitting machine into a whole through the sliding table base 4, the rack 15 and the rack 16.

During operation, firstly, the sliding table screw rod 2 is driven to rotate by the left-side cutter longitudinal moving motor 1, the sliding table moving seat 6 is moved on the sliding table base 4, so that a required cutter on the sliding table base 4 is aligned with the bamboo splitting position 13, meanwhile, the cutter replacing guide track 5 is aligned with the bamboo splitting position cutter guide track 14, the cutter extracting motor 9 is started to drive the cutter extracting device 10 to move, the movable pulley 8 is moved from the cutter replacing guide track 5 to the bamboo splitting position cutter guide track 14, the required cutter is extracted from the cutter frame to the bamboo splitting position 13, when the bamboo splitting process is carried out, the right-side cutter longitudinal moving motor 1 drives the right-side sliding table screw rod 2 to rotate, the right-side sliding table moving seat 6 is moved, so that the required cutter for the next bamboo splitting in the right-side sliding table base 4 is aligned with the cutter extracting device 10, and after the bamboo splitting process is completed, draw back the cutter and the tool holder that this time cut open bamboo in-process used to left side slip table base 4 in, right side cutter extraction motor 9 starts simultaneously, draws the removal of tool extraction device 10 through tool extraction lead screw 11 drive, and the cutter that will prepare cut open the bamboo next time and use is taken out from the right side, then the left side continues to prepare to cut open the required cutter of bamboo next time, so the circulation is reciprocal, and uninterrupted operation accomplishes the tool changing. Therefore, the alternating automatic tool changing mechanism has the design functions of realizing uninterrupted alternating tool changing, reducing the tool changing time and reducing the equipment volume.
