Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 4, the present invention provides a beam driving apparatus of a high precision plasma cutting machine, including:
a first rack guide rail 1 and a first driver 2 engaged with the first rack guide rail; the invention shows that the pitch of the second rack guide 3 is more precise than that of the first rack guide 1, and the aim is to provide two different moving states of the driving beam end bracket 5.
The beam end support 5, namely an end support structure for mounting a beam bearing a plasma cutting machine main body, is arranged at two ends of the beam, and the first driver 2 and the second driver 4 are mounted on the beam end support 5;
the device comprises a beam guide rail 6, namely a bracket 5 at the end part of the beam, which is arranged at two sides of a bed body for placing a workpiece to be cut, and a first rack guide rail 1 and a second rack guide rail 3 are arranged on the beam guide rail 6;
the second driver 4 is engaged with and disengaged from the second rack guide rail 3 through a telescopic assembly 7; the first driver 2 is meshed with the first rack guide rail 1 or the second driver 4 is meshed with the second rack guide rail 3 to drive the beam end bracket 5 to move linearly along the beam guide rail 6.
The working principle of the invention is as follows: when the plasma cutting machine main body is located at the initial position and moves to the target position for a long distance, the first rack guide rail 1 with the large tooth pitch/screw pitch (relative to the second rack guide rail 3) and the first driver 2 are matched to drive the beam end support 5, when high-precision cutting is needed, the second rack guide rail 3 with the small tooth pitch/screw pitch and the second driver 4 are matched to drive the beam end support 5, and therefore high-precision cutting (aiming at cutting in the length direction of the bed body) of the plasma cutting machine is considered, meanwhile, the plasma cutting machine can also move to the position needing cutting efficiently, and beam driving efficiency of the plasma cutting machine is effectively improved.
Of course, the first driver 2 does not operate while the second rack rail 3 and the second driver 4 cooperate to drive the beam end bracket 5, and since the pitch of the second rack rail 3 is more precise than that of the first rack rail 1, the driving operation is performed in a unit stroke between the second driver 4 and the second rack rail 3 even if the first driver 2 and the first rack rail 3 are engaged in a state where the first driver 2 is not operated.
Plasma cutting machine main part and crossbeam structure have certain weight, when the plasma cutting machine main part removed along the crossbeam structure (the width direction of the bed body), its motion inertia momentum that acts on the crossbeam can make the combination between crossbeam and the guide rail take place micro crossbeam skew, the slope atress is emptyd easily when numerical control plasma cutting machine used, this just makes plasma cutting machine produce the error in the ascending cutting of crossbeam side easily, and numerical control plasma cutting machine is not convenient for adjust the elasticity between the structure of being connected or contact or meshing between crossbeam guide rail support 5 and crossbeam guide rail 6.
To this end, the present invention provides two specific embodiments of rail mounting structures based on the above-described design of the first rack rail 1 and the second rack rail 3:
firstly, as shown in fig. 2, the first rack guide 1 is installed on the outer side surface of the beam guide 6 along the length direction of the beam guide 6, and the second rack guide 3 is installed on the inner side surface of the beam guide 6 along the length direction of the beam guide 6; the telescopic assembly 7 drives the second driver 4 to move along the direction vertical to the beam guide rail 6 to be meshed with the second rack guide rail 3;
thus, when the second rack guide 3 is engaged by the second driver 4, the second rack guide 3 exerts a force (in the width direction of the bed) away from the bed, i.e. a force on the beam guide 6, and for the two ends of the beam of the cutting machine, the two outward forces can realize stable connection between the beam end bracket 3 and the beam guide 6 (to eliminate the assembly gap between the beam end bracket 3 and the beam guide 6).
Of course, in the present invention, the second driver 4 and the second rack guide 3 are prevented from being excessively engaged (the acting force far away from the bed body is large, and the engagement rotation between the second driver 4 and the second rack guide 3 is influenced). By providing the elastic contact member 10 on the telescopic assembly 7, the elastic contact member 10 contacts with one side surface of the beam guide 6 when the telescopic assembly 7 drives the second driver 4 to engage with the second rack guide 3.
Secondly, as shown in fig. 3, the first rack guide rail 1 and the second rack guide rail 3 are installed on the same side surface of the beam guide rail 6 in parallel along the length direction of the beam guide rail 6, and the second rack guide rail 3 is located above the first rack guide rail 1; an included angle exists between the direction of the second driver 4 driven by the telescopic assembly 7 to move linearly and the second rack guide rail 3; the second rack guide 3 comprises a base and conical teeth arranged on the base, the purpose of the structure is to eliminate backlash in the gear movement process, and therefore the second rack guide 3 is preferably conical teeth.
Because the straight gears can be completely meshed in the moving process, a movement error is generated in the moving-to-moving stopping process even if the two straight gears can be completely meshed, and if the first rack guide rail 1 and the second rack guide rail 3 are both straight gears or are both bevel gears, the movement error always exists.
The purpose of the second rack guide 3 is to use tapered teeth is that, when the telescopic assembly 7 (specifically, a pneumatic cylinder or a hydraulic cylinder or a linear motor) drives the second driver 4 to engage with the second rack guide 3, due to the structural nature of the conical teeth themselves, the second drive 4 and the second rack bar 3 can be engaged at the beam end bracket 5 under the engagement driving movement of the first rack bar 1 and the first drive 2, at the same time, the telescopic assembly 7 is equivalent to generate a component force to the second rack guide 3 along the length direction of the second rack guide 3 when the second driver 4 is engaged with the second rack guide 3, thus forcing the second rack bar 3 and the second drive 4 to be tightly coupled, at this time, since the driving action of the beam end bracket 5 is taken over by the much tighter second rack bar 3 and second drive 4, thereby further eliminating the motion error between the first rack guide 1 and the first driver 2.
Further, in order to match the driving state of the beam end bracket 5 (advance or retreat along the beam rail 6) by the first rack rail 1 and the first driver 2, the above-described configuration is described. The number of the second drivers 4 is two, the two second drivers 4 are arranged on two sides of the first driver 2 in a mirror symmetry mode, when the cross beam end part support 5 is in a forward state or a backward state and reaches a precise cutting operation position, the telescopic assembly 7 drives the second drivers 4 in the same direction (taking the position of the first driver 2 as a reference) as the forward state or the backward state to work, and the second drivers 4 are meshed with the second rack guide rail 3.
Further, the present invention provides another structural embodiment of the cross rail 6 in which the first rack rail 1 and the second rack rail 2 are located on the same side surface of the cross rail 6, and the second driver 4 is in the same plane as the first driver 2, and the plane is perpendicular to the cross rail 6.
The cross beam guide 6 comprises a longitudinal guide body 61, an angle groove 62 is arranged on the top of the longitudinal guide body 61, the angle groove 62 comprises a first inclined guide plane 63 and a second inclined guide plane 64, and the joint of the first inclined guide plane 63 and the second inclined guide plane 64 is positioned on the width plane of the longitudinal guide body 61, in this embodiment, the second driver 4 needs to be vertically connected with the second inclined guide plane 64, and the opposite second driver 4 is obliquely connected with the cross beam end bracket 5.
The first rack rail 1 is horizontally mounted on the first inclined rail plane 63, the second rack rail 3 is mounted on the second inclined rail plane 64, and the tooth surface of the second rack rail 3 faces the first inclined rail plane 63.
A baffle plate 8 is arranged at the upper part of the first rack guide rail 1, and the baffle plate 8 protrudes out of the first rack guide rail 1; the first driver 2 is provided with a rolling bearing 9, the surface of the rolling bearing 9, which is in contact with the baffle 8, is an inclined plane, and the included angle between the inclined plane and the horizontal plane is an acute angle.
The purpose of this is that, when the telescopic assembly 7 drives the second drive 4 into engagement with the second rack guide 3, due to the gravity action of the beam and the plasma cutting machine body, the telescopic assembly 7 gives a reaction force in the telescopic direction of the telescopic assembly 7 to the transverse end bracket 5, this reaction force is divided into a force along the length of the beam and a force perpendicular to the length of the beam, and the action force in the direction vertical to the length direction of the cross beam is counteracted due to the limitation of the contact between the rolling bearing 9 and the baffle plate 8, the main force applied to the cross beam is the action force along the length direction of the cross beam, therefore, the stability of connection between the whole body of the beam and the plasma cutting machine body and the beam guide rail 6 is realized, and the stability of the beam end support 5 moving along the beam guide rail 6 when the second driver 4 is meshed with the second rack guide rail 3 is further improved, as shown in fig. 4.
Furthermore, the end of the second driver 4 in the present invention is provided with an elastic contact 10, the elastic contact 10 includes a shaft 101 mounted at the end of the second driver 4 along the length direction of the second driver 4, a spring 102 is sleeved on the shaft of the shaft 101, and a rolling element 103 is mounted at the end of the shaft 101 far away from the end of the second driver 4.
In order to limit the connection state of the rolling member 103 and the second inclined guide rail plane 64, the second inclined guide rail plane 64 is provided with a rolling groove 104 matched with the rolling member 103, wherein the rolling member 103 can be a ball bearing or a roller bearing, the rolling groove 104 is arranged along the length direction of the second inclined guide rail plane 64, and the rolling member 103 cannot be separated from the rolling groove 104 but can move along the rolling groove 104.
It is further noted that in the present invention, the second drive 4 can be moved synchronously with the first drive 2 before the second drive 4 is not engaged with the second rack guide 3, i.e. the second drive 4 and the first drive 2 always maintain the same phase angle of the engaged rack guide.
In the invention, the first driver 2 and the second driver 4 both comprise a driving motor and a gear arranged on an output shaft of the driving motor, the gear comprises a conical gear or a straight gear, namely, the gear is meshed with the first rack guide rail and the second rack guide rail through the gear, and certainly, in the actual use process, the connection between the driving motor and the gear needs a speed reducer to avoid the output shaft of the driving motor from directly driving the gear so as to protect the gear.
In the embodiment of fig. 3, the rolling bearing 9 is mounted on the output shaft between the drive motor and the gear.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
