[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, reduce the clamping and replacement time of workpieces during the machining process, and thus improve production efficiency.

[0003] When using a vertical machining center for processing, the fixation of the workpiece becomes more important due to the variable milling direction. In the prior art, two sets of matching clamping claws are mostly used to fix the workpiece. This can indeed ensure the processing accuracy for thick and non-deformable materials. 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 are mostly to fix the four corners of the material. However, such thinner materials may be slightly bent and deformed 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

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0019] 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 a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0020] See also Figure 1 to Figure 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.

[0021] A drilling tool 11 is arranged in the machining center body 1. It should be noted that, in the present 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 arranged 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 the second positioning components to pre-fix the workpiece to be processed; the first positioning component includes a supporting plate 2 fixedly installed in the machining center body 1, and a supporting member 3 is arranged on the supporting plate 2, and multiple groups of balls 4 are arranged on the side of the supporting member 3 away from the supporting plate 2. When in use, the workpiece to be processed is placed on the supporting member 3 and is in abutment with the ball 4. At this time, when the workpiece to be processed occurs in any direction on the supporting 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, the accuracy of adjusting the position of the workpiece to be processed can be improved; the first positioning component 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 a double-headed cylinder 8 arranged on the supporting plate 2, and a limiting member 6 is arranged 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.

[0022] 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 stopper 5, the double-headed cylinder 8 can be controlled to move, so that the two groups 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 further abutted against the stopper 5 under the guidance of the first inclined surface 601, and after the limiting member 6 is fitted with the side of the workpiece to be processed, the workpiece to be processed can be limited along its length direction, thereby ensuring the position accuracy of the workpiece to be processed in the length direction when the workpiece to be processed is processed.

[0023] 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 them 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 and prevent the limiting members 6 from interfering with the workpiece to be processed, thereby reducing the difficulty of placing the workpiece to be processed to a certain extent.

[0024] 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, it can be carried out according to actual production needs and on the premise of meeting the driving requirements.

[0025] See also Figure 3 , Figure 6~Figure 8 The second positioning assembly includes a transverse axis 17 fixedly connected to the side plate 16, a telescopic plate is slidably mounted on the transverse axis 17, a pushing piece 20 is provided at one end of the telescopic plate away from the transverse axis 17, a third inclined surface 2002 is formed on the side of the pushing piece 20 facing the workpiece to be processed, and a circular arc portion 2001 is provided at one end of the pushing piece 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 mounted in the follower sleeve 18, and the telescopic plate 19 is connected to the pushing piece 20; the follower sleeve 18 and the telescopic plate 19 are connected by a pulling spring 22.

[0026] 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.

[0027] Through the above-mentioned arrangement, in the process of placing the workpiece to be processed, the stop member 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.

[0028] 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; a connecting plate 12 is also provided on the linear drive module 10, and the connecting plate 12 is rotatably connected to the pressure rollers 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.

[0029] 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 forces it to be pressed downward, so that the workpiece to be processed can fit with the supporting member 3, so as 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.

[0030] In detail, as the linear drive module 10 moves, the drill 11 and the pressure roller 13 connected thereto can move synchronously, and when the drill 11 moves to a 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 straightness of the workpiece to be processed and improve the straightness of the processing position area.

[0031] See also Figure 2 , Figure 5~Figure 9 The lifting member 14 is a trapezoidal structure, and a flat surface 1402 is formed on the lifting member 14, and second inclined surfaces 1401 are arranged 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 when the trigger shaft 21 moves upward, the group of second positioning assemblies can move away from the workpiece to be processed; 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 arranged 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.

[0032] After completing the pre-positioning of the workpiece to be processed, the pushing members 20 on the multiple sets of second positioning components 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 rise 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 lateral movement away from the workpiece to be processed, so that the pushing member 20 can be separated from the workpiece to be processed and at the same time produce a lateral displacement.

[0033] Furthermore, in the present embodiment, the pushing member 20 has the function of applying force in the width direction of the workpiece to be processed, thereby realizing the 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. At the same time, the pushing member 20 gives way to eliminate the squeezing force of the pushing member 20 on the workpiece to be processed toward the middle, and prevents the squeezing force from further gathering 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 the width direction thereof. 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 be extended along the width direction thereof, thereby making the workpiece tend to be flat, thereby further improving the processing accuracy.

[0034] 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; on the other hand, after the pressure roller 13 moves to the predetermined position, the corresponding pushing member 20 can be separated from the workpiece to be processed, 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.

[0035] The method for processing a workpiece using the multi-axis dynamic locking anti-displacement vertical machining center of the worktable comprises: conveying the workpiece to be processed from the side of the machining center body 1 to the first positioning assembly, 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 assembly, the second positioning assembly 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 assembly is controlled to move, and at this time the first positioning assembly can position the workpiece to be processed along its length direction; starting the pressure assembly to move, 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 assembly is combined with the second positioning assembly, so that the second positioning assembly at the moving position of the pressure roller 13 is separated from the workpiece to be processed, and then the drilling tool 11 processes the workpiece to be processed.

At the same time, the pressure assembly is combined with the second positioning assembly, so that the second positioning assembly at the moving position of the pressure rollers (13) is separated from the workpiece to be processed, and then the drill (11) processes the workpiece to be processed.
