Description

Technical Field

[0001] The invention relates to workpiece processing, in particular to a worktable structure for a vertical machining center. Background Art

[0002] A vertical machining center refers to a machining center in which the spindle axis is set vertically to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds and small shells. The vertical machining center can complete processes such as milling, boring, drilling, tapping and cutting threads. The accuracy, strength and stability of the machine tool worktable have a direct impact on the quality, accuracy and processing efficiency of the machined parts during mechanical processing.

[0003] When installing workpieces on traditional workbenches, most of them are clamped in the gap of the workbench to achieve stability of the workpiece during processing. Although it can initially form a fixation, when the processing accuracy is high, the workpiece is still prone to jumping due to the contact and separation of the processing tool head, and errors are prone to occur during multi-sided processing. Therefore, the existing technology sets corresponding tooling in the workbench to fix the workpiece, but the tooling needs to be constantly replaced due to the different sizes of the workpieces, and the tooling itself needs to be repeatedly replaced with a special fixing structure, which increases the difficulty of fixing the workpiece, thereby weakening the processing accuracy of the machining center and reducing the yield rate of batch workpieces.

[0004] Therefore, this case aims to provide a worktable structure for a vertical machining center, which can not only effectively fix the workpiece after installation, but also does not directly act on the workpiece itself to avoid damage to the workpiece, thereby improving the yield rate of the workpiece and further improving the accuracy of the machining center. Summary of the invention

After the clustering member is expanded, the power piece drives the tie piece to move upward and causes the clustering member to retract inward, so that the clustering member is tightly attached to the outside of the workpiece.

[0007] As a further improvement, the clustering member includes four hinge rods arranged in the through cavity, the lower ends of the hinge rods are provided with clustering plates, the lower ends of the clustering plates are provided with elastic binding seats, and after the workpiece is inserted, the clustering plates are stretched open and then adhered to the elastic binding seats.

[0008] As a further improvement, the clustering plate includes a hard steel plate connected to the hinge rod, a spring steel plate is provided at the lower end of the hard steel plate, and the lower end of the spring steel plate is connected to an elastic binding seat.

[0009] As a further improvement, the elastic binding seat includes a square plate connected to the elastic steel sheet, a plurality of the square plates form a square seat, and a compensation gasket is arranged below the square plate.

[0010] As a further improvement, a guide slot is provided on the partition plate, and the lateral positioning member includes a transverse frame movably connected in the guide slot, and an upper positioning portion and a lower positioning portion are respectively provided at the upper and lower ends of the transverse frame, and the upper positioning portion is affixed to the outer side of the workpiece, and the lower positioning portion is affixed to the outer side of the clustering member.

[0011] As a further improvement, the transverse frame includes an upper T-shaped rod and a lower T-shaped rod slidably arranged on the upper and lower ends of the partition plate, and the upper T-shaped rod and the lower T-shaped rod are connected by a connecting piece slidably arranged in the guide slot.

[0012] As a further improvement, a positioning cylinder is provided in the positioning seat, the positioning cylinder is connected to the lower positioning part, the lower positioning part includes a side push block connected to the positioning cylinder, and the side push block is connected to a crimping block attached to the outside of the clustering member.

[0013] As a further improvement, the anchor member includes an upper movable seat connected to a hard steel sheet, a connecting rod is connected to the lower end of the upper movable seat, a lower movable seat is fixedly connected to the lower end of the connecting rod, and the lower movable seat is connected to the power member.

[0014] The beneficial effects of the present invention are: In existing vertical machining centers, the workpiece is mostly fixed directly in the installation gap of the worktable by rigid means, and then different tools are switched to process the workpiece. In this way, the workpiece is either fixed too tightly, resulting in damage to the lower end position of the workpiece, or it is not fixed tightly enough, resulting in the workpiece jumping when the tool enters and exits, and the workpiece shifts during multi-stage processing. Therefore, the present invention hollows out the middle position of the traditional worktable body through the provision of a middle docking component, and arranges partition plates and blocking blocks therein to form a number of through cavities that are roughly adapted to the size of the workpiece, and by arranging a clustering piece in the through cavity, when the workpiece enters, the workpiece will be fixed by the clustering piece, so that when setting the installation gap, there is no need to customize the size of the installation gap to be too narrow, and the bottom area of ​​the workpiece can still be fixed, thereby reducing the possible jumping of the workpiece at the bottom of the stage.

[0015] When the clustering piece is being bound, it has a square structure, so it can adapt to square or round workpiece blanks. Under normal conditions, it is affected by the torsion spring inside the hinge rod, and all the clustering pieces will gather towards the middle until a workpiece enters through the cavity, then the clustering pieces will be directly stretched open. Due to the reset effect of the clustering piece itself, the clustering piece will hold the outer side of the workpiece tightly and fix it, so that the workpiece is initially fixed.

[0016] The cluster sheet restraint is performed through multiple stages. The part that initially contacts the workpiece is contacted by a hard steel sheet, thereby forming a rigid single-point fixation at the top. At the end, it is gradually restrained and fixed through surface contact using an elastic spring steel sheet. At the bottom of the workpiece, it is supported by an elastic binding seat, thereby achieving three-point fixed limit at the middle of the outer side, the outer bottom, and the outer bottom surface.

[0017] If only the bottom of the workpiece is fixed, then its stabilizing force is definitely insufficient for a workpiece of a certain length. Therefore, the present invention provides an adaptive component on the basis of the bottom being limited by the middle docking component. By fixing the adaptive component at a lower middle position, the middle position of the entire workpiece is fixed in the horizontal direction, thereby avoiding left and right deviations.

[0018] When fixing in the middle position, it is not a single-end upper or lower fixation, but the upper positioning part and the lower positioning part are used simultaneously to fix the upper and lower ends of the workpiece, thereby limiting the workpiece while providing a certain limiting and restraining function for the hard part of the cluster.

[0019] The upper positioning part and the lower positioning part are not driven in sections. Since the area below the entire workbench is relatively narrow, it is not suitable to set up more driving structures. Therefore, the upper positioning part and the lower positioning part in the present invention are connected by a transverse frame, and a linked upper and lower limit structure is formed by the upper T-bar, lower T-bar, and connecting plate.

[0020] When the clustering part acts on the workpiece, it relies on its own resilience to restrain it, and its actual restraining force is relatively small. However, if pressure is applied directly from the side, it is easy to deform relative to the inclined clustering part. Therefore, the present invention is further provided with a clustering push-up assembly on the basis of the above, and a clustering push-up assembly is arranged downward on the outer side of the clustering part. The upward thrust makes the gathering force of the entire clustering part greater, and because it acts on the side of the clustering part, the gathering effect can be directly improved, and there is no need to apply excessive force to the clustering part. While increasing the restraining force, the deformation of the clustering part is avoided to a great extent, thereby improving the practicality of the present invention.

[0021] During the setting process of the clustering and pushing-up components, it needs to be set more flexibly so that the clustering pieces can fit more closely to the workpiece. Therefore, the anchor in the present invention is movably set at both ends, so that the anchor has a higher degree of freedom. When pushing up, the power part can push and pull the connecting rod upward, thereby achieving the effect of pushing up the bottom and further achieving the cohesive effect of the clustering part.

To be more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0033] Reference Figure 1 to Figure 7As shown, a worktable structure for a vertical machining center includes a worktable body 10, on which a plurality of installation slots 11 for installing workpieces are opened, a connecting table 20 is connected to the lower end of the worktable body 10, and a movable seat 30 cooperating with a screw rod is connected to the lower end of the connecting table 20, and guide clamps 40 fixed below the connecting table 20 are arranged at both ends of the movable seat 30, and the worktable structure also includes: a middle docking assembly 50, including a partition plate 51 arranged in the middle of the inner side of the connecting table 20, a contrasting slot corresponding to the installation slot 11 is opened on the partition plate 51, and a plurality of spaced-apart blocking blocks are filled in the contrasting slot, and a plurality of through cavities 54 are formed between the plurality of blocking blocks, and the interior of the through cavities 54 is arranged There is a clustering piece 55, and the workpiece is inserted into the installation seam 11 and then passes through the control seam, and is clamped and fixed by the clustering piece 55 through the through cavity 54 in the control seam; the adaptive component 60 includes a positioning seat fixed on the partition plate 51, and a lateral positioning piece 62 is provided on the inner side of the positioning seat. When the workpiece is fixed by the clustering piece 55, the lateral positioning piece 62 is pressed against the outer side of the clustering piece 55 and the workpiece; the clustering push-up component 70 includes a tie piece 71 provided below the clustering piece 55, and the lower end of the tie piece 71 is provided with a power piece 72 fixed to the inner bottom of the connecting platform 20. After the clustering piece 55 is opened, the power piece 72 drives the tie piece 71 to move upward and retract the clustering piece 55 inward, so that the clustering piece 55 is tightly attached to the outer side of the workpiece.

[0034] When the workpiece is installed, the workpiece is embedded into the installation slot 11 of the workbench body 10, so that the workpiece extends into the hole of the installation slot 11 until it enters the through cavity 54 of the control slot for fixation.

[0035] In existing vertical machining centers, the workpiece is usually fixed directly in the installation slot 11 of the workbench by rigid means, and then different tools are switched to process the workpiece. In this way, the workpiece is either fixed too tightly, resulting in damage to the lower end position of the workpiece, or is not fixed tightly enough, resulting in the workpiece jumping when the tool enters and exits, and the workpiece shifts during multi-stage processing. Therefore, the present invention hollows out the middle position of the traditional workbench body 10 by setting a middle docking component 50, and sets a partition plate 51 and a blocking block therein to form a plurality of through cavities 54 that are roughly adapted to the size of the workpiece, and sets a clustering member 55 in the through cavity 54. When the workpiece enters, it will be fixed by the clustering member 55. Therefore, when setting the installation slot 11, there is no need to customize the size of the installation slot 11 to be too narrow, and the bottom area of ​​the workpiece can still be fixed, thereby reducing the possible jumping of the workpiece at the bottom of the stage.

[0036] In this embodiment, the clustering piece 55 has a square structure when being bound, so that it can adapt to square or round workpiece blanks. Specifically, the clustering piece 55 includes four hinges 551 arranged in the through cavity 54, and the lower end of the hinge 551 is provided with a clustering piece 552, and the lower end of the clustering piece 552 is provided with an elastic binding seat 553. After the workpiece is inserted, the clustering piece 552 is stretched open and then adhered to the elastic binding seat 553. Under normal conditions, under the influence of the torsion spring inside the hinge 551, all the clustering pieces 552 will gather towards the middle until a workpiece enters through the through cavity 54, and then the clustering pieces 552 will be directly stretched open. Due to the reset effect of the clustering piece 552 itself, the clustering piece 552 will hold the outer side of the workpiece tightly and fix it, so that the workpiece is initially fixed.

[0037] The binding of the clustering plate 552 is performed through multiple sections, so the clustering plate 552 is arranged in sections, and the clustering plate 552 includes a hard steel plate 5521 connected to the hinge rod 551, and the lower end of the hard steel plate 5521 is provided with an elastic steel plate 5522, and the lower end of the elastic steel plate 5522 is connected to an elastic binding seat 553, and the part that initially contacts the workpiece is contacted with the part of the hard steel plate 5521, thereby forming a rigid single-point fixation at the top position, and at the end position, it is gradually bound and fixed by means of surface contact through the elastic elastic steel plate 5522, and at the bottom position of the workpiece, it is supported by the elastic binding seat 553, thereby realizing three-point fixed limit of the outer middle part, the outer bottom, and the outer bottom surface.

[0038] The entire elastic binding seat 553 is tightly attached to the bottom of the workpiece. Although it does not completely cover it, it will present a wrapping manner. Specifically, the elastic binding seat 553 includes a square plate 5531 connected to the elastic steel sheet 5522. Several square plates 5531 form a square seat. A compensation gasket 5532 is arranged under the square plate 5531, so that the wrapping limit area can be changed as the workpiece goes deeper, thereby improving the stabilization effect.

[0039] If only the bottom of the workpiece is fixed, its stabilizing force is definitely insufficient for a workpiece of a certain length. Therefore, the present invention provides an adaptive component 60 on the basis of the bottom being limited by the middle docking component 50. By fixing the adaptive component 60 at a lower middle position, the middle position of the entire workpiece is fixed in the horizontal direction, thereby avoiding the phenomenon of left and right deviation.

[0040] When fixing in the middle position, it is not a single-end upper or lower fixation, and a guide slot is provided on the partition plate 51 of this embodiment, and the lateral positioning member 62 includes a transverse frame 621 movably connected in the guide slot, and the upper and lower ends of the transverse frame 621 are respectively provided with an upper positioning portion 622 and a lower positioning portion 623, and the upper positioning portion 622 is attached to the outer side of the workpiece, and the lower positioning portion 623 is attached to the outer side of the clustering member 55. The upper positioning portion 622 and the lower positioning portion 623 are simultaneously implemented to fix the workpiece at both the upper and lower ends, thereby providing a certain limiting and restraining function to the hard part of the clustering member 55 while restricting the workpiece.

[0041] The upper positioning portion 622 and the lower positioning portion 623 are not driven in sections. Since the area under the entire workbench is relatively narrow, it is not suitable to set up more driving structures. Therefore, the transverse frame 621 of this embodiment includes an upper T-bar 6211 and a lower T-bar 6212 slidably set at the upper and lower ends of the partition plate 51. The upper T-bar 6211 and the lower T-bar 6212 are connected by a connecting piece 6213 slidably set in the guide gap. The upper positioning portion 622 and the lower positioning portion 623 are connected by a transverse frame 621, and a linked upper and lower limit structure is formed by the upper T-bar 6211, the lower T-bar 6212, and the connecting piece 6213.

[0042] The lower positioning portion 623 is provided with active power. Specifically, a positioning cylinder 611 is arranged in the positioning seat. The positioning cylinder 611 is connected to the lower positioning portion 623. The lower positioning portion 623 includes a side push block 6231 connected to the positioning cylinder 611. The side push block 6231 is connected to a crimping block 6232 attached to the outer side of the clustering member 55. The crimping block 6232 cooperates with the clustering member 55. The crimping block 6232 has a certain elasticity to avoid direct damage to the clustering member 55. The upper positioning portion 622 cooperates with the workpiece in a rigid manner. It should be specifically noted that the length of the upper positioning portion 622 is longer than that of the lower positioning portion 623.

[0043] When the clustering member 55 acts on the workpiece, it relies on its own resilience to restrain it, and its actual restraining force is relatively small. However, if pressure is applied directly from the side, it is easy for the clustering member 55 that is set obliquely to deform. Therefore, the present invention is further provided with a clustering push-up assembly 70 on the basis of the above. The clustering push-up assembly 70 is arranged downward on the outer side of the clustering member 55. The upward thrust makes the gathering force of the entire clustering member 55 greater, and because it acts on the side of the clustering member 55, the gathering effect can be directly improved, and there is no need to apply excessive force to the clustering member 55, thereby improving the binding force while avoiding the deformation of the clustering member 55 to a great extent, thereby improving the practicality of the present invention.

[0044] During the setting process of the clustering and pushing-up assembly 70, it needs to be set more flexibly so that the clustering sheet 552 can fit more closely to the workpiece. Therefore, the anchor 71 of this embodiment includes an upper movable seat 711 connected to the hard steel sheet 5521, and the lower end of the upper movable seat 711 is connected to a connecting rod 712, and the lower end of the connecting rod 712 is fixedly connected to a lower movable seat 713, and the lower movable seat 713 is connected to the power member 72. The anchor 71 is set in a movable manner at both ends, so that the anchor 71 has a higher degree of freedom. The power member 72 can push and pull the connecting rod 712 upward when pushing up, thereby achieving the bottom pushing effect, and then achieving the cohesive effect of the clustering member 55.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
