Description

Technical Field

[0001] The present invention relates to a machining device, in particular to a vertical machining center. Background Art

[0002] A vertical machining center refers to a machining center in which the spindle axis is vertically arranged with respect to the workbench, and is mainly applicable to machining complex parts such as plate-like, disc-like, mold and small shell-like parts. 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 workbench have a direct impact on the quality, accuracy and machining efficiency of the machined parts in machining.

[0003] When installing a workpiece on a traditional workbench, it is mostly fixed by clamping the workpiece in the gap of the workbench to achieve the stability of the workpiece during machining. Although it can be initially fixed, when the machining accuracy is high, the workpiece is still prone to jump due to the contact and separation of the machining tool head, and errors are likely to occur during multi-sided machining. Therefore, corresponding fixtures are provided in the workbench in the prior art to fix the workpiece, but due to the different sizes of the workpieces, the fixtures need to be continuously replaced, and the fixtures themselves also need to repeatedly replace special fixing structures, thereby increasing the fixing difficulty of the workpiece, weakening the machining accuracy of the machining center, and reducing the yield rate of batch workpieces.

[0004] Therefore, the present case aims to provide a vertical machining center that can not only effectively fix the installed workpiece, but also does not directly act on the workpiece itself to avoid damaging the workpiece, thereby improving the yield rate of the workpiece and further improving the accuracy of the machining center.

[0015] 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.

[0016] 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.

[0021] The beneficial effects of the present invention are:

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] After each adjustment of the workpiece, the screw rods of the front and rear adjustment components and the left and right adjustment components must be in a locked state. However, the workbench will inevitably shake during the processing. In order to avoid the influence of the workbench on the screw rod, the present invention also arranges a contact structure on the basis of the above. When the movable tool holder, the front and rear adjustment components, and the left and right adjustment components are moved into place and no longer move, the control end will control the friction contact piece to extend downward, thereby directly unloading a part of the force exerted on the workbench downward through the friction contact piece, and since the friction coefficient of the bottom surface of the friction contact piece is relatively high, the possibility of the workbench swinging left and right is relatively low.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more, unless otherwise specifically defined.

[0045] Refer to Figures 1 to 9As shown, a vertical machining center comprises: a machine base 1 consisting of a base and a column, a movable tool holder 2 which can slide up and down is arranged on the column, a front-and-back adjustment component 3 is arranged above the base, a left-and-right adjustment component 4 is arranged above the front-and-back adjustment component 3, a workbench is movably arranged on the left-and-right adjustment component 4, and the workbench comprises: a workbench main body 10, a plurality of installation slots 11 for installing workpieces are opened on the workbench main body 10, a connecting table 20 is connected to the lower end of the workbench main body 10, a movable seat 30 matched with a screw rod is connected to the lower end of the connecting table 20, guide clamps 40 fixed under the connecting table 20 are arranged at both ends of the movable seat 30, and also comprises: a middle docking component 50, comprising a partition plate 51 arranged at 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, a plurality of spaced-apart blocking blocks are filled in the contrasting slot, a plurality of through cavities 54 are formed between the plurality of the blocking blocks, and the through cavities A bunching piece 55 is arranged inside 54, and the workpiece is inserted into the installation seam 11 and passes through the control seam, and is clamped and fixed by the bunching piece 55 through the through cavity 54 in the control seam; an adaptable component 60 includes a positioning seat fixed on the partition plate 51, and a lateral positioning piece 62 is arranged on the inner side of the positioning seat. When the workpiece is fixed by the bunching piece 55, the lateral positioning piece 62 is pressed against the outer side of the bunching piece 55 and the workpiece; a bunching push-up component 70 includes a tie piece 7 arranged below the bunching piece 55. 1, the lower end of the tie member 71 is provided with a power member 72 fixed to the inner bottom of the connecting table 20, after the clustering member 55 is opened, the power member 72 drives the tie member 71 to move upward and makes the clustering member 55 gather inward, so that the clustering member 55 is closely attached to the outer side of the workpiece; the contact structure includes two groups of friction contact members 81 arranged on the bottom surface of the worktable body 10, and the friction contact member 81 is provided with a control end electrically connected to the movable tool holder 2, the front and rear adjustment component 3, and the left and right adjustment component 4.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] The entire elastic fastening seat 553 is closely attached to the bottom of the workpiece. Although it does not completely enclose the workpiece, it will present a wrapping manner. Specifically, the elastic fastening seat 553 includes a square plate 5531 connected to the spring steel sheet 5522. A number of the square plates 5531 form a square seat. A compensation gasket 5532 is arranged below the square plate 5531, so that the wrapping and limiting area can be changed according to the position where the workpiece penetrates, thereby improving the stability effect.

[0051] If only the bottom of the workpiece is fixed, then for a workpiece with a certain length, its stability force is definitely insufficient. Therefore, on the basis that the bottom of the present invention is limited by the middle docking component 50, an adaptive component 60 is further provided. By fixing at a position slightly below the middle of the adaptive component 60, a horizontal fixation of the middle position of the entire workpiece is formed, thereby avoiding the phenomenon of left-right deviation.

[0052] When fixing at the middle position, it is not a single-end upper or lower fixation. In the present embodiment, a guiding slot is opened on the partition plate 51. The lateral positioning member 62 includes a transverse movement frame 621 movably connected in the guiding slot. Upper positioning portions 622 and lower positioning portions 623 are respectively arranged at the upper and lower ends of the transverse movement frame 621. 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 beam member 55. By using the method of simultaneously performing the upper positioning portion 622 and the lower positioning portion 623, fixation is carried out at both the upper end position and the lower end position of the workpiece, thereby providing a certain limiting and binding function for the rigid part of the beam member 55 while restricting the workpiece.

[0053] The upper positioning portion 622 and the lower positioning portion 623 are not driven in sections. Since the area below the entire workbench is relatively narrow, it is not suitable to set a large number of driving structures. Therefore, in the present embodiment, the transverse movement frame 621 includes an upper T-shaped rod 6211 and a lower T-shaped rod 6212 slidably arranged at the upper and lower ends of the partition plate 51. The upper T-shaped rod 6211 and the lower T-shaped rod 6212 are connected by a connecting piece 6213 slidably arranged in the guiding slot. The upper positioning portion 622 and the lower positioning portion 623 are connected by a transverse movement frame 621. By arranging the upper T-shaped rod 6211, the lower T-shaped rod 6212, and the connecting piece 6213, a linkage upper and lower limiting structure is formed.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] After each adjustment of the workpiece, the screw rods of the front and rear adjustment components 3 and the left and right adjustment components 4 must be in a locked state. However, the workbench will inevitably shake during the processing. In order to avoid the influence of the workbench on the screw rod, the present invention also arranges a contact structure on the basis of the above. When the movable tool holder 2, the front and rear adjustment components 3, and the left and right adjustment components 4 are moved into place and no longer move, the control end will control the friction contact piece 81 to extend downward, thereby directly unloading a part of the force exerted on the workbench downward through the friction contact piece 81, and since the friction coefficient of the bottom surface of the friction contact piece 81 is relatively high, the possibility of the workbench swinging left and right is relatively low.

[0058] Among them, the two sets of the friction contact members 81 are arranged oppositely. The friction contact member 81 includes a hydraulic cylinder 811 fixedly connected to the bottom surface of the workbench main body 10. A friction plate 812 is locked at the lower end of the hydraulic cylinder 811. The friction plate 812 is attached to the bottom of the inner side of the left and right adjustment assembly 4. After the control end detects that each mechanism is in place, the hydraulic cylinder 811 is driven to descend and the friction plate 812 is brought into contact with the bottom of the inner side of the left and right adjustment assembly 4, so as to form a limiting effect when at rest. It should be emphasized that when the friction contact member 81 is moving, it is in a staggered state with the lead screw and other rib plates in the left and right adjustment assembly 4, and no mutual jamming will occur.

[0059] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. 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.
