Description

Technical Field

[0001] The invention relates to the technical field of machining centers, in particular to a vertical machining center with a multi-axis dynamic locking anti-displacement working table and a method thereof. Background Art

[0002] Vertical machining centers are capable of performing a variety of machining operations, such as milling, drilling, tapping, cutting, etc. By integrating multiple functions, they can complete multiple processes at one time, reducing the clamping and replacement time of workpieces during the machining process, thereby improving production efficiency.

[0003] When using a vertical machining center for processing, the fixation of the workpiece becomes more important due to its variable milling direction. In the existing technology, two sets of adaptive clamping claws are mostly used to fix the workpiece. This can indeed ensure the processing accuracy for materials with large thickness and not easy to deform. However, for thinner materials, the above fixing method may cause the material to bend due to stress, which indirectly affects the processing accuracy.

[0004] Of course, there are corresponding clamping forms for thinner materials. These clamping forms mostly fix the four corners of the material. However, such thinner materials may undergo slight bending deformation during production and transportation. Only by fixing the four corners, it is impossible to correct their straightness, which can still affect the processing accuracy. Especially for workpieces made of softer materials, only partial clamping is more likely to cause deformation of the workpiece. Summary of the Invention

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0029] See also Figures 1 to 10 In an embodiment of the present invention, a vertical machining center with a multi-axis dynamic locking anti-displacement worktable includes: a machining center body 1, a positioning mechanism, a pressure assembly and a side plate 16.

[0030] A drilling tool 11 is provided in the machining center body 1. It should be noted that, in this application, the drilling tool 11 is used as a general term, and its specific structure includes a driving device, a control device and a drill bit, wherein the driving device can control the drill bit to rotate at a rated speed, and the control device can control the drill bit to perform lifting and lowering actions and forward, backward, left and right actions within a certain range in the horizontal plane; the positioning mechanism is provided in the machining center body 1, and the positioning mechanism includes a first positioning component and multiple groups of second positioning components, and the first positioning component cooperates with the multiple groups of second positioning components to pre-fix the workpiece to be processed; the first positioning component includes a support plate 2 fixedly installed in the machining center body 1, and a support member 3 is provided on the support plate 2, and multiple groups of balls 4 are provided on the side of the support member 3 away from the support plate 2. When in use, the workpiece to be processed is placed on the support member 3 and is in abutment with the balls 4. At this time, when the workpiece to be processed occurs in any direction on the support member 3 When the workpiece to be processed moves, the ball 4 can roll, thereby reducing the resistance of the workpiece to be processed on the supporting member 3, making it more convenient to adjust the position of the workpiece to be processed, and to a certain extent, improving the accuracy of adjusting the position of the workpiece to be processed; the first positioning assembly also includes a stopper 5 arranged at one end of the supporting plate 2 and a two-way driving structure arranged at the other end of the supporting plate 2. When one end of the workpiece to be processed abuts against the stopper 5, the two-way driving structure can stop the other end of the workpiece to be processed. The two-way driving structure includes two groups of slide grooves 201 symmetrically arranged on the supporting plate 2, and a slider 7 is slidably installed in the slide groove 201. The slider 7 is connected to the double-headed cylinder 8 arranged on the supporting plate 2, and a limiting member 6 is provided on the slider 7. One end of the limiting member 6 is provided with a first inclined surface 601. The first inclined surface 601 can cooperate with the workpiece to be processed to make the workpiece to be processed move toward the stopper 5.

[0031] When the workpiece to be processed is placed on the supporting member 3, force can be applied to one end of the workpiece to be processed to make the workpiece to be processed move. At this time, due to the presence of the ball 4, the workpiece to be processed can be moved more conveniently, and when one end of the workpiece to be processed abuts against the stop member 5, the double-headed cylinder 8 can be controlled to move, so that the two sets of limiting members 6 can move closer to each other, and when the first inclined surface 601 abuts against the edge of the workpiece to be processed, the workpiece to be processed can be guided by the first inclined surface 601 to further abut against the stop member 5, until the limiting member 6 fits with the side of the workpiece to be processed, at this time, the workpiece to be processed can be limited along its length direction, ensuring the position accuracy of the workpiece to be processed in the length direction when the workpiece to be processed is processed.

[0032] Among them, when the workpiece to be processed is placed on the supporting member 3, the two sets of limiting members 6 are in a separated state, and the distance between the two is greater than the width of the workpiece to be processed, so as to facilitate the placement of the workpiece to be processed on the supporting member 3, prevent the limiting members 6 from interfering with the workpiece to be processed, and reduce the difficulty of placing the workpiece to be processed to a certain extent.

[0033] Furthermore, the above-mentioned double-headed cylinder 8 can also adopt a double-headed electric telescopic rod or a double-headed hydraulic cylinder. All three are references to the existing technology, so this application will not go into details. During actual assembly, the best one can be selected according to actual production needs and on the premise of meeting the driving requirements.

[0034] See also Figure 3 、 Figures 6 to 8 The second positioning assembly includes a transverse axis 17 fixedly connected to the side plate 16, and a telescopic plate is slidably installed on the transverse axis 17. A pushing member 20 is provided at the end of the telescopic plate away from the transverse axis 17, and a third inclined surface 2002 is formed on the side of the pushing member 20 facing the workpiece to be processed, and an arc portion 2001 is provided at one end of the pushing member 20; the telescopic plate includes a follower sleeve 18 slidably connected to the transverse axis 17, the interior of the follower sleeve 18 is a hollow structure, and a telescopic plate 19 is slidably installed in the follower sleeve 18, and the telescopic plate 19 is connected to the pushing member 20; the follower sleeve 18 and the telescopic plate 19 are connected by a pulling spring 22.

[0035] In the initial state, the pulling spring 22 is in a natural state. At this time, there is a certain gap between the pushing member 20 and the supporting member 3, which is smaller than the thickness of the workpiece to be processed. At the same time, the distance between the end of the arc portion 2001 away from the pushing member 20 and the supporting member 3 is greater than the thickness of the workpiece to be processed, so that when the workpiece to be processed is pushed toward the stop member 5, the workpiece to be processed can abut against the arc portion 2001, and the arc portion 2001 is used to push the pushing member 20 upward. In this process, the pulling spring 22 can be stretched. At the same time, under the action of the pulling spring 22, the pushing member 20 has a force toward the workpiece to be processed, so that the workpiece to be processed can fit with the third inclined surface 2002 on the pushing member 20, and has a squeezing force on the workpiece to be processed along its width direction, thereby playing a positioning effect on the workpiece to be processed along its width direction, ensuring the position accuracy of the workpiece to be processed in the width direction during the processing. In this way, precision processing can be achieved, and production efficiency and the quality of processed parts can be improved.

[0036] Through the above-mentioned arrangement, in the process of placing the workpiece to be processed, the stopper 5 cooperates with the limiting member 6 to realize the positioning of the workpiece to be processed along its length direction, and the corresponding two groups of pushing members 20 cooperate to position the workpiece to be processed in the width direction. The cooperation of the two can achieve the effect of pre-positioning the workpiece to be processed, thereby ensuring the stability and accuracy of the workpiece to be processed during the placement and processing process.

[0037] See also Figure 5 The pressure assembly is connected to the drilling tool 11, and two groups of pressure rollers 13 are rotatably mounted on the pressure assembly, and the pressure assembly is adapted to the trigger shaft 21 connected to the second positioning assembly; the pressure assembly includes a bracket 9 fixedly connected to the machining center body 1, and a linear drive module 10 is provided on the bracket 9, and the linear drive module 10 is connected to the drilling tool 11; the linear drive module 10 is also provided with a connecting plate 12, and the connecting plate 12 is rotatably connected to the pressure roller 13, and a lifting member 14 is provided on the connecting plate 12, and the lifting member 14 is adapted to the trigger shaft 21 connected to the telescopic plate 19.

[0038] After completing the pre-positioning of the workpiece to be processed, the pressure roller 13 is in a state of being dislocated and separated from the workpiece to be processed. When the workpiece to be processed needs to be processed, the linear drive module 10 is controlled to move. At this time, the pressure roller 13 can follow the movement of the linear drive module 10, and when the pressure roller 13 contacts the workpiece to be processed, the pressure roller 13 can act on the side of the workpiece to be processed, so that the workpiece to be processed has a force that is forced to press downward, so that the workpiece to be processed can be fitted with the supporting member 3 to improve the straightness of the workpiece to be processed, prevent the workpiece to be processed from being slightly bent due to internal stress or other reasons, causing position deviation during processing, and further improve the processing accuracy.

[0039] In detail, as the linear drive module 10 moves, the drill tool 11 and the pressure roller 13 connected thereto can move synchronously, and when the drill tool 11 moves to the predetermined processing position, the pressure roller 13 can squeeze the workpiece to be processed within the processing position area downward until it fits with the supporting member 3, so as to perform real-time correction on the flatness of the workpiece to be processed and improve the flatness of the processing position area.

[0040] See also Figure 2 、 Figures 5 to 9The lifting member 14 has a trapezoidal structure, and a flat surface 1402 is formed on the lifting member 14. Second inclined surfaces 1401 are provided on both sides of the flat surface 1402. When the trigger shaft 21 cooperates with the second inclined surface 1401, the trigger shaft 21 can drive the telescopic plate 19 to move upward; the side plate 16 is arranged in the machining center body 1 and is connected to the supporting plate 2 through the vertical rod 15. A guide groove is formed on the side plate 16. The second positioning assembly cooperates with the guide groove and can move the group of second positioning assemblies away from the workpiece to be processed when the trigger shaft 21 moves upward; a groove wheel 23 is connected to the telescopic plate 19, and the groove wheel 23 can roll in the guide groove; the guide groove includes a vertical groove 1602 provided on the side plate 16 and an inclined groove 1601 connected to the vertical groove 1602. When the telescopic plate 19 moves upward, the groove wheel 23 can roll in the vertical groove 1602 and the inclined groove 1601 in sequence.

[0041] After completing the pre-positioning of the workpiece to be processed, the pushing members 20 on the multiple sets of second positioning assemblies can fit with the side of the workpiece to be processed, and when the linear drive module 10 drives the drilling tool 11 and the pressure roller 13 to move, when the second inclined surface 1401 on the lifting member 14 abuts against the trigger shaft 21, the trigger shaft 21 can move upward under the guidance of the second inclined surface 1401 and drive the telescopic plate 19 to move upward. At this time, the groove wheel 23 connected to the telescopic plate 19 can move upward along the vertical groove 1602, and The pushing member 20 can be separated from the workpiece to be processed, and during the continuous upward movement of the telescopic plate 19, when the groove wheel 23 moves to the end of the vertical groove 1602, the groove wheel 23 can move along the inclined groove 1601, and the follower sleeve 18 can slide along the length direction of the horizontal axis 17. At this time, the pushing member 20 can not only move upward relative to the workpiece to be processed, but also produce a horizontal movement away from the workpiece to be processed, and while the pushing member 20 is separated from the workpiece to be processed, the pushing member 20 can produce a lateral displacement.

[0042] Furthermore, in this embodiment, the pushing member 20 has the function of applying force toward the width direction of the workpiece to be processed, thereby realizing positioning of the workpiece to be processed in the width direction. However, in actual processing, when the pressure roller 13 moves to the pushing member 20, the pressure roller 13 can further squeeze the workpiece to be processed, so that the workpiece to be processed is flattened to both sides, and at the same time, the pushing member 20 gives way, eliminating the squeezing force of the pushing member 20 on the workpiece to be processed toward the middle, and preventing the squeezing force from further converging toward the middle due to the action of the pushing member 20 when the pressure roller 13 moves to the current pushing member 20, thereby increasing the unevenness of the workpiece to be processed along its width direction. That is, when the pushing member 20 gives way, when the pressure roller 13 acts on a certain area of ​​the workpiece to be processed, the workpiece to be processed can extend along its width direction, thereby making the workpiece tend to be flat, thereby further improving the processing accuracy.

[0043] Based on the above arrangement, the pushing member 20 can, on the one hand, pre-position the workpiece to be processed in the width direction, and on the other hand, can separate the corresponding pushing member 20 from the workpiece to be processed after the pressure roller 13 moves to the predetermined position, thereby avoiding the situation in which the pushing member 20 forms a stop state in the width direction of the workpiece during the lateral movement of the pressure roller 13, resulting in the two sides of the workpiece in the width direction being flat and the curvature of the middle part becoming larger, thereby further improving the processing accuracy.

[0044] The method for processing a workpiece using the multi-axis dynamic locking anti-displacement vertical machining center with a worktable includes: transporting the workpiece to be processed from the side of the machining center body 1 to the first positioning component, and then applying force to the workpiece to be processed to make the workpiece to be processed move along its length direction. When the workpiece to be processed is combined with the second positioning component, the second positioning component can position the workpiece to be processed along its width direction, and when the workpiece to be processed moves to the point where it cannot be pushed, the first positioning component is controlled to move, and at this time the first positioning component can position the workpiece to be processed along its length direction; starting the pressure component and making the two groups of pressure rollers 13 connected thereto act on the side of the workpiece to be processed, and at the same time the pressure component is combined with the second positioning component, so that the second positioning component at the moving position of the pressure roller 13 is separated from the workpiece to be processed, and then the drill 11 processes the workpiece to be processed.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
