Abstract

An automatic cutting machine relates to the technical field of cutting machines, in particular to a cutting machine with a cutter with high motion control precision. The technical scheme is as follows: a control rod is connected between the two fixed seats, the control rod is connected with an encoder, and the encoder is connected with the PLC control part; the left and right side mechanisms of the utility model are connected through a balancing rod, so that the left and right pressure of the machine can be balanced; and a coder controlled by a PLC program is installed in the middle of the control rod, so that the depth of the cutting machine is directly controlled by distance in the whole cutting process, the cutting machine is not influenced by time and speed, the accuracy of the cutting depth is improved, and the quality of a cut object is ensured.

Description

Automatic cutting machine

Technical field:

The utility model relates to the cutting machine technical field, refers in particular to the high cutting machine of motion control precision that a kind of severing is neat, crush-cutting is set up height, cutter uniformly automatically.

Background technology:

At present, along with the updating and reforming of industrial technology, cutting machine is as industrial a kind of indispensable manufacturing machine, and its technological innovation is also more and more big; Existing cutting machine is as shown in Figure 1, 2: comprise upper machine body 1, lower body 2, the right and left of lower body 2 has two oil cylinders 4 respectively, about two oil cylinders be connected with upper machine body 1 by two pillars 3 respectively, and about four pillar 3 lower ends one holder 5 is respectively arranged, there is the piece 6 that is rotationally connected the lower end of holder 5, the lower end of contiguous block 6 is hinged with a mobilizable triangle steering block 7, and the other end of triangle steering block 7 connects left and right sides mechanism by connecting rod 8; As a whole, this kind cutting machine by two oil cylinders, mechanical linkage reach upper machine body 1 relative to (lower body 2) parallel moving, the quality that cuts with lifting; Yet, this kind cutting machine is when the action that upper and lower body is finished cut, because of triangle steering block 7 and connecting rod 8 not at grade, both are because of the long-term changing of the relative positions, then can cause both sides mechanism deflection, thereby have influence on the quality that cuts thing, and connecting rod 8 as stressed when too quickly, too inhomogeneous because of two ends, also can cause fractureing of connecting rod 8; The depth of cut of particularly serious is upper machine body 1 can't be controlled effectively, causes easily to cut quantity not sufficient or excessively; Cause to cut thoroughly, damage problems such as cutter and cutting machine damage, brought certain quality problem and economic loss for producer and user.

The utility model content:

The purpose of this utility model is to provide a kind of cutting machine that can accurately control the depth of cut of upper machine body; It can promote the quality that cuts, and prolongs the service life of machine, reduces production costs, and it is programme-controlled fully that realization cuts.

The utility model is achieved by the following technical solution: the every side of lower body is fixed with two oil cylinders, and lower body links to each other by being enclosed within the outer pillar of oil cylinder with upper machine body, and the pillar lower end connects a holder, and holder links to each other with contiguous block one end; The contiguous block lower end is hinged with eccentric hinge, and the other end of two eccentric hinges is connected by a balancing pole; Be connected with control lever between described two holders, control lever connects an encoder, and encoder links to each other with the PLC control section.

Above-mentioned control lever parallels with the board face of lower body; Encoder links to each other with control lever central authorities; Balancing pole links to each other with a following tie point of off-centre hinge respectively, and it is paralleled with the board face of lower body.

The utility model promptly can be used to the pressure about the balancing machine platform owing to by a balancing pole left and right sides mechanism is connected; And be equipped with one by the programme controlled encoder of PLC in the middle of the control lever, thereby realize that cutting machine in whole severing process, directly comes controlling depth with distance, be not subjected to the influence of time and speed, improve the accuracy of the severing degree of depth, guarantee to cut the quality of thing.

Description of drawings:

Fig. 1 looks schematic diagram for existing cutting machine master;

Fig. 2 is existing cutting machine schematic side view;

Fig. 3 looks schematic diagram for the utility model master;

Fig. 4 is the PLC control program of the utility model encoder 12.

The specific embodiment:

See accompanying drawing 3, the utility model mainly includes upper machine body 1, lower body 2, pillar 3, oil cylinder 4, holder 5, contiguous block 6, eccentric hinge 9, balancing pole 10, lower body 2 every sides are fixed with two oil cylinders 4, lower body 2 links to each other by the pillar 3 that is enclosed within outside the oil cylinder 4 with upper machine body 1, pillar 3 lower ends connect a holder 5, and holder 5 links to each other with contiguous block 6 one ends; Contiguous block 6 lower ends are hinged with eccentric hinge 9, and balancing pole 10 links to each other with a following tie point of off-centre hinge 9 respectively, and it is paralleled with the board face of lower body 2; Because eccentric hinge 9 is an arc, then when being subjected to too quickly pressure, then because of its lifting surface area is big, it cushions great efforts, can alleviate the suffered impact of whole board; And be arrangeding in parallel of balancing pole 10 can make the board face synchronized parallel movement of the cutter of upper machine body 1 drive with respect to lower body 2 so that the reaction of oil cylinder is very fast; 5 of described two holders are connected with control lever 11, and the axis of control lever 11 parallels with the board face of lower body 2; And, connecting an encoder 12 in the stage casing of control lever 11, encoder 12 links to each other with the PLC control section.

When upper machine body 1 drive cutter cut article, control lever 11 is also synchronously parallel moving under the drive of holder 5, makes the motion of cutter directly utilize the motor reaction of control lever 11 to come out; Thereby, when adjustment upper machine body 1 cuts object, control lever 11 promptly can be synchronously down to the severing position, owing to be connected with an encoder 12 of being controlled by the high speed port of PLC in the middle of the control lever 11, encoder 12 promptly can send the high speed port that a signal is given PLC after arriving the severing position, PLC receives the fuel tap that this signal can be controlled the oil cylinder 4 that is moving, and makes its commutation, thereby controls the degree of depth that cuts thing with distance; Because the precision of encoder 12 is higher, and the program of PLC (is specifically seen attached illustrated in Figure 4, when practical application, can be different, only it can reach purpose and gets final product) speed of service is fast, thereby the fuel tap of oil cylinder 4 is commutated, and realize accurate control to tool motion, promote the quality that cuts; This moment, PLC and the signal that receives also preserved when cutting same object, also can simplify the part steps that repeats to cut emplacement depth like this; And when the range of movement of initial definite cutter, can cut thing according to need and set.
