Description

Technical Field

[0001] The present invention relates to the technical field of high-end equipment manufacturing, and in particular to a box-type crossbeam anti-deformation servo control compensation system and a compensation method. Background Art

[0002] The beams of gantry machining centers are all metal structures. Steel welded beams are light in weight and have high tensile strength, but the process is difficult, the vibration resistance is low, and the thermal deformation is difficult to control. High-strength cast beams have a large damping coefficient and strong vibration resistance. The casting process is mature, but they are heavy and have weak bending resistance. They are prone to bending deformation within their own weight, which affects the machining accuracy.

[0003] Due to the large span of the support points, the beam will bend and deform under the dual influence of its own weight and load, especially in the Y and Z axis planes. Taking a gantry machine tool with a span of 3000mm as an example, without human intervention, the bending deformation of the beam under its own weight can be as high as 0.15mm, which has a huge impact on the processing of high-precision parts.

[0004] The current empirical treatment method is reverse deformation compensation processing, which processes the original straight beam into an arched shape to offset the bending deformation of the beam. In the actual production process, due to reasons such as material, process, and personnel quality, the processing curve will change, resulting in the processed arched curve not matching the actual deformation amount, and repeated processing occurs. The beam is huge in size and is prone to secondary deformation during transportation and processing. The one-time success rate of the reverse deformation processing technology is low, thereby reducing production efficiency, which is undesirable for technicians in this field.

[0040] The present invention is further described below with reference to the accompanying drawings and specific embodiments, but is not intended to be a limitation of the present invention.

[0041] Embodiment 1:

[0042] like Figure 1 and 2 As shown, the present invention discloses a box-type crossbeam anti-deformation servo control compensation system. Specifically, the compensation system includes an anti-bending beam structure, a servo drive mechanism, a horizontal detection device 11 and a control system; the box-type crossbeam 1 includes a top plate, a bottom plate, and a front plate and a rear plate connected between the top plate and the bottom plate, a crossbeam guide rail is fixedly arranged on the front plate, the top plate includes a first side and a second side arranged opposite to the first side, and the first side of the top plate is adjacent to the crossbeam guide rail, and the second side of the top plate is away from the crossbeam guide rail; the anti-bending beam structure is at least partially located in the box-type crossbeam 1; at least one servo drive mechanism is arranged in the box-type crossbeam 1, and the at least one servo drive mechanism is rotatably connected to the anti-bending beam structure along the axial direction of the box-type crossbeam 1 in turn. On the beam structure, each servo drive mechanism is connected to a supporting crank connecting rod 7, one end of the supporting crank connecting rod 7 is connected to a supporting wheel 8, and the supporting wheel 8 is in contact with the lower surface of the first side of the top plate, the other end of the supporting crank connecting rod 7 is fixed on the lower surface of the second side of the top plate, and the middle part of the supporting crank connecting rod 7 is rotatably connected to the servo drive mechanism (specifically, the middle part of the supporting crank connecting rod 7 is hinged to the servo drive mechanism); the at least one horizontal detection device 11 is arranged at intervals on the upper surface of the first side of the top plate; the control system is respectively connected to the servo drive mechanism and the horizontal detection device 11, so as to control the action of the drive rod of the servo drive mechanism through the detection data information of the horizontal detection device 11.

[0043] Specifically, the above-mentioned anti-bending beam structure includes an anti-bending beam body 2 and an anti-bending beam bracket 3 located below the anti-bending beam body 2. The present invention places a large-section high-strength welded part (anti-bending steel beam) inside the box-type cross beam 1, which can bear the bending moment, and the anti-bending beam body 2 is connected to the cross beam support (not shown in the figure) below the base plate through the anti-bending beam bracket 3 located at both ends of the anti-bending beam body 2, so that the anti-bending beam body 2 and the cross beam support (the cross beam support is a column or a cross beam slide) are connected as a whole to form another set of closed frame structure (that is, an independent rigid frame structure is formed).

[0044] In a preferred embodiment of the present invention, the servo drive mechanism includes a servo cylinder 5 and a servo driver (not shown) connected to the servo cylinder 5. Preferably, the servo cylinder 5 is an electric servo cylinder or a hydraulic servo cylinder; specifically, a plurality of servo cylinders are distributed on the anti-bending beam body 2. The servo cylinder 5 is a piston structure. Driven by the servo cylinder 5, servo-controlled feeding can be performed according to demand. The servo cylinder 5 is equipped with a closed-loop control system, so that the feeding amount of the driving rod (i.e., the piston rod) can be accurately controlled. The tail end of the servo cylinder 5 is connected to the anti-bending beam body 2 through a hinge structure (i.e., the servo drive mechanism is rotatably arranged on the anti-bending beam structure through a hinge), so that the thrust of each servo cylinder 5 is greater than or equal to the moving load on the box-type crossbeam 1.

[0045] In a preferred embodiment of the present invention, the level detection device 11 is an electronic level. A plurality of electronic levels are arranged on the top of the box beam 1 to provide feedback on the bending deformation trend of the box beam 1. Specifically, taking a gantry machine tool mechanism as an example, the arrangement range of the electronic level is the support range of the gantry structure (including the column part). The closer the arrangement spacing, the more accurate the measurement result of the bending deformation of the box beam 1.

[0046] In a preferred embodiment of the present invention, one end of the supporting crank connecting rod 7 provided inside the box-type cross beam 1 is fixed to the first side of the top plate through a fixed hinge 6, and the middle node is hingedly connected to the piston rod of the servo cylinder 5. The other end of the supporting crank connecting rod 7 is provided with a supporting wheel 8, and the supporting wheel 8 is in direct contact with the inner wall of the casting on the side of the cross beam guide rail, and the material of the supporting wheel 8 is a high damping wear-resistant material, which can partially absorb the amplitude of the mechanical vibration of the box-type cross beam 1. The supporting crank connecting rod 7 is driven by the piston rod of the servo cylinder 5, and the supporting wheel 8 installed at one end of the supporting crank connecting rod 7 can be lifted and lowered. The bottom of the servo cylinder 5 is hinged, and the bottom of the servo cylinder 5 is installed with a servo cylinder base hinge 4, and the servo cylinder base hinge 4 is fixed to the anti-bending beam body 2 by bolts.

[0047] Specifically, when the box beam 1 is in a free state without load, the box beam 1 will bend and deform under the action of its own gravity. Multiple electronic levels will collect the position data at this time to form the original bending deformation curve of the box beam 1. The deformation trend of the box beam 1 can be calculated through mathematical model calculation. When the box beam 1 is installed with a transverse slide and a vertical ram, the deformation curve of the box beam 1 will change. Since the transverse slide and the vertical ram make transverse reciprocating motion on the box beam 1, the deformation amount on the inner side of the fixed support section of the box beam 1 will increase. The electronic level can record the position change of the transverse slide and the vertical ram at each position on the box beam 1, and form a dynamic curve of the bending deformation of the box beam 1 through a mathematical model. According to the dynamic curve of the bending deformation of the box-type beam 1, the piston rod action of the servo cylinder 5 at each position is controlled by the servo controller, and the bending deformation of the box-type beam 1 is compensated in real time according to the real-time data feedback of the electronic level. The dynamic curve of the bending deformation of the box-type beam 1 is compensated by the segmented support of the servo drive mechanism. The servo cylinder 5 transfers the thrust of the anti-bending deformation to the anti-bending beam body 2 through the servo cylinder base hinge 4.

[0048] In a preferred embodiment of the present invention, the servo cylinder 5 is internally provided with an absolute position detection function, so that the movement position of the piston rod of the servo cylinder 5 can be accurately controlled, and each servo cylinder 5 is provided with an independent servo drive, power pipeline and position detection, and is connected to an electric control cabinet 9 through an outlet interface 10, and the electric control cabinet 9 is located on the rear side of the box-type beam 1 (that is, the electric control cabinet 9 is fixed on the outer wall of the rear plate of the box-type beam 1).

[0049] Specifically, the control system is a beam bending compensation servo control system, and the control system is arranged in the electric control cabinet 9 to control the movement of all servo cylinders 5 and collect the real-time data of all electronic levels, and perform correction and compensation for the bending deformation of the box-type beam 1 under various environmental conditions according to the real-time data feedback of all electronic levels. The control system can realize the motion control of each servo cylinder 5; the control system feeds back the data to the machine tool numerical control system through the signal cable, so as to monitor the real-time state of the bending deformation of the box-type beam 1. Through the secondary development of the machine tool servo system, the automatic compensation function of the bending deformation and processing state of the box-type beam 1 can be realized.

[0050] Here, the detection data information obtained by the horizontal detection device 11 when the crossbeam is unloaded (the load here generally refers to the transverse slide and the vertical slide, and the transverse slide and the vertical slide make transverse reciprocating motion on the box-type crossbeam 1) is the original detection data information, and the detection data information obtained by the horizontal detection device 11 when the crossbeam is loaded is the collected detection data information;

[0051] In a preferred embodiment of the present invention, the control system includes a first decoding and transcoding module 1001, a database establishment module 1002, a data comparison module 1003, a second decoding and transcoding module 1004 and a collection data abnormality alarm module 1005; the first decoding and transcoding module 1001 is connected to the horizontal detection device 11 to decode and transcode the original detection data information obtained by the horizontal detection device 11 in the programmable logic processor when the beam is unloaded to generate converted original detection data information, and when the beam is loaded, the collection detection data information obtained by the horizontal detection device 11 is decoded and transcoded in the programmable logic processor to generate converted collection detection data information; the database establishment module 1002 is connected to the first decoding and transcoding module 1001 to convert the original detection data according to the conversion The data information establishes an original model data curve library, and establishes a collection model data curve library according to the converted collection detection data information; the data comparison module 1003 is connected to the database establishment module 1002 to compare the original model data curve in the original model data curve library with the collection model data curve in the collection model data curve library to generate a compensation model data curve; the second decoding and transcoding module 1004 is respectively connected to the data comparison module 1003 and the servo drive mechanism to decode and transcode the compensation model data curve in the programmable logic processor to generate execution data compatible with the servo drive mechanism and output it to the servo drive mechanism; the collection data abnormality alarm module 1005 is connected to the data comparison module 1003 to issue an alarm when the comparison result of the data comparison module exceeds a preset range.

[0052] Embodiment 2:

[0053] like Figure 3 As shown, the present invention discloses a box-type beam anti-deformation servo control compensation method, based on the above-mentioned box-type beam anti-deformation servo control compensation system, specifically, the method comprises the following steps:

[0054] Step S1, when the box-type cross beam has no load, obtaining original detection data information of the horizontal detection device.

[0055] Step S2, decoding and transcoding the original detection data information in a programmable logic processor to generate converted original detection data information, and establishing an original model data curve library according to the converted original detection data information.

[0056] Step S3, when the box-type cross beam is loaded, acquiring the collected detection data information of the horizontal detection device.

[0057] Step S4, decoding and transcoding the collected detection data information in a programmable logic processor to generate converted collected detection data information, and establishing a collection model data curve library according to the converted collected detection data information.

[0058] Step S5, compare the acquisition model data curve in the acquisition model data curve library with the original model data curve in the original model data curve library. If the comparison results are different and do not exceed the preset value, a compensation model curve is generated and the next step (i.e., step S6) is continued; if the comparison result exceeds the preset range, an abnormal acquisition data alarm operation is performed; if the comparison results are the same, the operation is terminated (and the host computer is informed that the correction is completed).

[0059] Step S6, decoding and transcoding the compensation model data curve in the programmable logic processor to generate execution data compatible with the servo drive mechanism and outputting the execution data to the servo drive mechanism.

[0060] In step S7, the servo drive mechanism performs a compensation action on the top plate according to the execution data, and after the compensation action is completed, returns to step S3.

[0061] Specifically, the principle of data processing in the present invention is: establish a theoretical (no-load) curve database and a database formed by real-time acquisition of current (loaded) data curves, compare the two databases, output the comparison result data (compensation model data curve) to the servo driver, and the driver performs a correction action, and reads the corrected acquisition model data curve in real time and compares it with the original model data curve in the original model data curve library. When the data are consistent, the correction is ended and the host computer is informed that the correction is completed; when there is a deviation from the theoretical (no-load) curve database, the database formed by the acquisition of the corrected data curve is re-executed, and the above actions are repeated until the comparison of the two data is consistent, the correction action is completed, and the host computer is informed; if the deviation between the acquired data and the theoretical data exceeds the preset range, an abnormal alarm for the acquired data is output.
