Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vertical processing equipment, in particular to a vertical processing center. Background Art
[0002] A vertical machining center is a CNC milling machine with a tool magazine, an automatic processing equipment that can realize batch processing automation. The vertical machining center mainly includes a column for supporting the tool, a support base for supporting the work platform, and a chip removal mechanism for automatically removing the chips generated by cutting and milling workpieces.
[0003] The installation and use of each structure influence and restrict each other. The support base is used to install the chip removal mechanism and the column. The column needs to avoid the chip removal mechanism and be installed on the support base outside the chip removal mechanism. In order to ensure the compactness of the overall structure, the contact surface between the two sides of the column and the support base is small, which leads to poor stability of the equipment. In addition, the column has to bear the total weight of the spindle box, tool magazine, electrical box, motor and other components as well as its own weight, which will cause the load to be concentrated on the two side walls of the column. In addition, due to the small contact surface with the support base, the rigidity of the column is poor and cannot bear heavier loads. In addition, during the cutting process of the workpiece, when the spindle box moves up and down, it causes the vibration of the entire equipment and the unstable change of the axial force, which leads to uneven movement and may cause the rigidity of the column itself to deteriorate.
[0004] The chip removal mechanism is to convey the metal debris mixed with cutting fluid to avoid debris accumulation and blockage that affects the normal operation of the equipment. Cutting fluid is an industrial liquid used to cool and lubricate tools and workpieces during metal cutting and grinding. When used, it will be mixed with metal debris and discharged, but the cutting fluid is scientifically compounded with a variety of super-functional additives. It also has good cooling performance, lubrication performance, rust prevention performance, oil removal and cleaning function, anti-corrosion function, and easy dilution characteristics, and needs to be collected, recycled and reused. Generally, manual cleaning is used for processing, but the labor intensity of workers is high, and during the cleaning process, the cutting fluid may be scattered everywhere, making the equipment operating environment worse, which in turn causes the servo motor of the machine tool circulating the cutting fluid to fail, increasing the frequency and cost of equipment maintenance, and cannot achieve clean production in the processing industry.
[0005] Therefore, the research purpose of the utility model is to design a column structure for a vertical machining center that can ensure the overall rigidity of the column to further ensure its load capacity by improving its own structure and eliminating the vibration caused by machine tool processing or equipment movement, and can promptly and quickly separate metal chips and cutting fluid.

[0019] The connecting mechanism includes a support base fixedly installed in the sub-groove and correspondingly arranged directly below the filter element.

A connecting rod is installed in the embedding hole to move up and down through a corresponding second elastic member. The other end of the connecting rod not connected to the second elastic member is connected to the filter element; a corresponding pressure gauge is fixedly connected to the bottom of the embedding hole in the middle, and the second elastic member in the embedding hole is fixedly connected to the pressure gauge.
[0020] The filter element is arranged at an interval from the inner side wall of the sub-groove, and the inner side wall of the sub-groove forms a corresponding aggregate groove by welding an annular member with an L-shaped cross section. The aggregate groove is arranged below the gap between the filter element and the sub-groove, and the width of the aggregate groove is greater than the width of the gap between the filter element and the sub-groove.
[0021] The sub-grooves are communicated by arranging the bottom of the partition plate at an interval from the bottom surface of the liquid guide groove, and both sides of the partition plate are fixedly welded to the inner side wall of the liquid guide groove. The bottom surface of the liquid guide groove is inclined downward, and a liquid outlet is arranged at the end of its downward inclination, and is connected to the cutting fluid collecting bucket through a corresponding liquid guide pipe and a liquid pumping pump.
[0022] Corresponding spiral members are provided on the chip guiding grooves. One end portion of each spiral member is spirally fixed on the driving rod, and the other end portion thereof extends through to the other end of the chip guiding hole of the mounting base.

A plurality of mounting holes are provided at the top of the connecting member and around the groove. The supporting parts of the columns respectively correspond to the column mounting portions of the mounting base and are tightly connected by bolts inserted through the mounting holes.
[0024] Advantages of the present utility model:
[0025] 1) In the present utility model, a plurality of convex edges are integrally formed at intervals up and down on the inner side wall of the hollow column. The overall strength of the column is enhanced by the integrally provided convex edges. X-shaped connecting members are respectively installed corresponding to the positions of the convex edges. The four end portions of the connecting members are welded to the four end corners of the column and the convex edges. The rigidity of the column is enhanced by the cooperation of the convex edges and the connecting members. The four end portions of the connecting members are provided in a stepped shape and are clamped and welded below the convex edges, and their sides are also welded to the column. Further, the convex edges and the column are connected by the connecting members. Then, the connecting members are used to install a vertically arranged vibration damping mechanism, and the vibration generated during machine tool processing is eliminated by the vibration damping mechanism. The column is improved in terms of its own structure and by eliminating the vibration generated by machine tool processing or equipment movement, thereby ensuring the overall rigidity of the column and further ensuring its load capacity.
[0026] 2) The utility model installs the vibration damping mechanism by using the connecting piece, and connects all the connecting pieces by using the vibration damping mechanism. By arranging a hollow cylinder filled with a lot of damping particles or vibration damping materials in the middle of the connecting piece, the mutual friction of the damping particles consumes energy, or the elastic deformation of the vibration damping materials absorbs and disperses part of the vibration energy, so as to eliminate part of the vibration generated by the machine tool processing on the column, thereby reducing the adverse effect of the vibration on the column and ensuring the rigidity of the column. Moreover, sleeves and sleeve rods are fixedly connected to the upper and lower ends of the hollow cylinder. A corresponding first elastic member is vertically fixedly connected in the sleeve. The sleeve rod on the upper connecting piece is inserted into the sleeve on the lower connecting piece with a clearance fit, and the lower end surface of the sleeve rod abuts against the first elastic member in the sleeve, so that each hollow cylinder is connected. When the vibration amount received by a local hollow cylinder is greater than the vibration amount that can be consumed or absorbed by it, the upper and lower hollow cylinders can be connected through the first elastic member, and the upper and lower hollow cylinders are assisted to further consume the excess vibration amount, and the upper and lower layers are connected and interact with each other to achieve a better vibration damping effect.
[0027] 3) The utility model directly installs an arc plate at the cross position in the middle of the connecting piece, and forms a receiving cavity with the connecting piece to fill a lot of damping particles or vibration damping materials. The mutual friction of the damping particles consumes energy, or the elastic deformation of the vibration damping materials absorbs and disperses part of the vibration energy, so as to eliminate part of the vibration generated by the machine tool processing on the column. Moreover, the damping particles or vibration damping materials are in direct contact with the connecting piece, which can better eliminate the vibration.
[0028] 4) The utility model integrally forms chip guiding grooves on both sides of the support base, integrally forms a mounting seat above the end of the chip guiding groove with the support base, and arranges chip guiding holes penetrating the mounting seat at the position of the mounting seat corresponding to the chip guiding groove. Not only are the chip guiding grooves communicated through the chip guiding holes, so that the chips can be discharged out smoothly and continuously, but also the cooperation of the hole walls can promote the discharge of the chips at the end part, effectively avoiding blockage at the end part and improving the chip discharging effect. The integrally arranged mounting seat not only facilitates chip discharging, but also is beneficial to forming sufficient support above the chip discharging mechanism for installing the column, and the contact surface for installing the column can be significantly increased, thereby improving the stability of the column support installation and ensuring the rigidity of the column.
[0029] 5) The utility model installs a corresponding sub-groove below the discharge end of the spiral member, and installs a filter member with a W-shaped longitudinal section corresponding to the spiral member in the sub-groove. The metal chips in the mixed cutting fluid are conveyed to the filter member, the cutting fluid is filtered through the filtrate holes and collected in the liquid guiding groove, and the metal chips are isolated and collected in the aggregate part along the inclined surface of the filter guiding part, achieving the effect of timely filtration.
[0030] However, due to the friction characteristics, metal debris is likely to accumulate on the filtering and guiding part and block the filtrate holes. Therefore, in the present utility model, a connection mechanism composed of a support base, a second elastic member, and a connecting rod is used to install the filtering member in an up-and-down movable manner. When the metal debris falls on the filtering member, it will drive the filtering member to vibrate up and down, thereby forming the effects of vibrating sieving and vibrating material guiding. In this way, filtering and material guiding are achieved, and the practical effect is further improved.
[0031] 6) To ensure the up-and-down movement setting of the filtering member, it needs to be spaced apart from the sub-grooves, which easily causes metal debris to fall into the liquid guide groove from the gap and mix with the filtered cutting fluid. Therefore, in the present utility model, a corresponding aggregate groove is formed by welding an annular member with an L-shaped cross-section on the inner side wall of the liquid guide groove below the filtering member, so as to collect the metal debris falling from the gap, effectively preventing it from falling into the filtered cutting fluid again and further ensuring the filtering effect.
[0032] 7) Although the present utility model can filter in real time and separately collect metal debris and cutting fluid, over a long time, it is easy for the accumulated amount of metal debris to exceed the bearing capacity of the filtering member, and it is necessary for personnel to observe the accumulation situation at any time and remove the metal debris in a timely manner, which increases the labor intensity. Therefore, in the present utility model, a corresponding pressure gauge is installed in the embedding hole of the support base, one end of the second elastic member is fixedly connected to the pressure gauge, and the other end is connected to the filtering member. As the material drops and accumulates to generate pressure, the alarm upper limit value of the pressure gauge is set according to the material quantity, and the personnel can process the metal debris in a timely manner according to the alarm, reducing the labor intensity.

Detailed implementation manners
[0044] For the convenience of those skilled in the art to understand, the structure of the present utility model will be further described in detail below in conjunction with the accompanying drawings:
[0045] Embodiment 1
[0046] Refer to Figures 1-6 and 8 - 11, a vertical machining center, comprising:
[0047] Support base 1;
[0048] Column 2, which is an inverted Y-shaped structure integrally formed by a rectangular mounting part 201 in the middle and support parts 202 on both sides. The column 2 is hollow, and a plurality of circles of convex edges 3 are integrally formed and arranged at intervals on the inner side wall of its rectangular mounting part 201 from top to bottom, and connecting pieces 4 corresponding to the convex edges 3 are provided. The connecting piece 4 is fixedly connected in the shape of an X in the convex edge 3, and its four end parts are all connected to the four end corners of the column 2 and the convex edge 3; A vibration damping mechanism 5 for eliminating the vibration formed during machine tool processing is vertically installed in the middle of the connecting piece 4;
[0049] The chip removal mechanism includes chip guide grooves 6 which are integrally formed in a V shape on both sides of the support base 1. The middle part of the chip guide groove 6 is recessed downward to form an arc shape. On the support base 1, an installation seat 7 adapted to the chip guide groove 6 is integrally formed and fixedly connected upward at the rear side of the chip guide groove 6. And a chip guide hole 703 corresponding to the position of the chip guide groove 6 is provided on the installation seat 7. A corresponding spiral member 8 is driven by a power mechanism on the chip guide groove 6. The end part of the spiral member 8 penetrates and extends to the other end of the chip guide hole 703 of the installation seat 7;
[0050] The filtering mechanism is installed in a liquid guide groove 9 on the side of the support base 1 where the chip guide hole is provided. The liquid guide groove 9 is divided into sub-grooves 10 corresponding to the number of the spiral members 8 by corresponding partition plates. In the sub-grooves 10, filtering members 11 with a W-shaped longitudinal section are installed to move up and down through corresponding connection mechanisms. When metal chips fall onto the filtering member 11, the filtering member 11 shakes up and down. The filtering member 11 includes a filtering and guiding part 1101 with a conical surface in the middle and corresponding to the directly lower position of the discharge end of the spiral member 8, and an aggregate part 1102 in the shape of a bucket formed by bending and folding upward from the end part of the filtering and guiding part 1101. A plurality of filtrate holes penetrating through the upper and lower parts thereof are evenly distributed on the side wall of the filtering and guiding part 1101;
[0051] The blade mounting seat 12 is arranged to move up and down through a vertical guide rail 13 and a screw drive mode installed on the column 2;
[0052] The working platform 14 is installed with a track base to move back and forth through a longitudinal guide rail 15 and a screw drive mode installed on the support base 1. The working platform 14 is installed on the track base to move left and right through a transverse guide rail 16 and a screw drive mode.
[0053] In the present utility model, not only a plurality of convex edges 3 are integrally formed at intervals up and down on the inner side wall of the hollow column 2, the overall strength of the column 2 is enhanced through the integrally arranged convex edges 3, and X-shaped connecting pieces 4 are respectively installed at the positions corresponding to the convex edges 3. The four end parts of the connecting piece 4 are welded to the four end corners of the column 2 and the convex edges 3. The rigidity of the column 2 is enhanced through the cooperation of the convex edges 3 and the connecting piece 4. The four end parts of the connecting piece 4 are arranged in a stepped shape and are clamped under the convex edges 3 and welded, and its side is also welded to the column 2. Further, the convex edges 3 and the column 2 are connected through the connecting piece 4; and then the connecting piece 4 is used to install a vibration damping mechanism arranged vertically. The vibration formed during the machining of the machine tool is eliminated by the vibration damping mechanism. The column 2 is improved in terms of its own structure and by eliminating the vibration generated by the machining of the machine tool or the movement of the equipment to itself, so as to ensure the overall rigidity of the column 2 and further ensure its load capacity.
[0054] The utility model integrally and integrally forms chip guiding grooves 6 on both sides of the support base 1, integrally forms a mounting seat 7 above the end of the chip guiding groove 6 and the support base 1, and arranges a chip guiding hole 703 penetrating the mounting seat 7 at the position of the mounting seat 7 corresponding to the chip guiding groove 6. Not only is the chip guiding groove 6 communicated through the chip guiding hole 703, so that the chips can be smoothly and continuously discharged outwards, but also the discharge of the chips at the end part can be promoted through the cooperation of the hole walls, effectively avoiding the blockage at the end part and improving the chip discharging effect; the integrally arranged mounting seat 7 not only facilitates chip discharging but also helps to form sufficient support above the chip discharging mechanism for mounting the column 2, and the contact surface for mounting the column 2 can be significantly increased, thereby improving the stability of the support and installation of the column 2 and ensuring the rigidity of the column 2.
[0055] The utility model installs a corresponding sub-groove 10 below the discharge end of the spiral member 8, and installs a filter member 11 with a W-shaped longitudinal section corresponding to the spiral member 8 in the sub-groove 10. The metal chips mixed with the cutting fluid are conveyed onto the filter member 11, the cutting fluid is filtered through the filtrate holes and collected in the liquid guiding groove 9, and the metal chips are isolated and collected in the aggregate part 1102 along the inclined surface of the filter guiding part 1101, achieving the effect of timely filtering.
[0056] However, due to the friction characteristics, the metal chips are easily accumulated on the filter guiding part 1101 and block the filtrate holes. Therefore, the utility model uses a connecting mechanism composed of a support base 17, a second elastic member 18 and a connecting rod 19 to install the filter member 11 up and down. When the metal chips fall on the filter member 11, they will drive the filter member 11 to vibrate up and down, thereby forming the effects of vibrating sieving and vibrating material guiding. In this way, filtering and material guiding can be realized, and the practical effect is further improved.
[0057] The vibration damping mechanism 5 includes a hollow cylinder 501 integrally and vertically fixed in the middle of the connecting member 4. A plurality of damping particles 502 or vibration damping materials are filled in the accommodating cavity of the hollow cylinder 501. The upper and lower end faces of the hollow cylinder 501 are respectively integrally fixed with a matching sleeve 503 and a sleeve rod 504, and a corresponding first elastic member 505 is vertically fixed in the sleeve 503. The sleeve rod 504 on the upper connecting member 4 is inserted into the sleeve 503 on the lower connecting member 4 with a clearance fit, and the lower end face of the sleeve rod 504 abuts against the first elastic member 505 in the sleeve 503.
[0058] The utility model installs a vibration damping mechanism by using a connecting piece 4, and also connects all the connecting pieces 4 by using the vibration damping mechanism. By arranging a hollow cylinder 501 filled with a plurality of damping particles 502 or vibration damping materials in the middle of the connecting piece 4, and utilizing the mutual friction energy consumption between the damping particles 502 or the elastic deformation of the vibration damping materials to absorb and disperse part of the vibration energy, part of the vibration generated by machine tool processing on the column can be eliminated, thereby reducing the adverse effect of the vibration on the column 2 and ensuring the stiffness of the column 2. Furthermore, sleeves 503 and sleeve rods 504 are fixedly connected to the upper and lower ends of the hollow cylinder 501. A corresponding first elastic member 505 is vertically fixedly connected inside the sleeve 503. The sleeve rod 504 on the upper connecting piece 4 is inserted into the sleeve 503 on the lower connecting piece 4 with a clearance fit, and the lower end surface of the sleeve rod 504 abuts against the first elastic member 505 inside the sleeve 503, so that the hollow cylinders 501 are connected to each other. When the vibration amount received by a local hollow cylinder 501 is greater than the vibration amount that can be consumed or absorbed by it, the upper and lower hollow cylinders 501 can be connected through the first elastic member 505, and the upper and lower hollow cylinders 501 can assist in further consuming the excess vibration amount, and the upper and lower layers are connected and interact with each other to achieve a better vibration damping effect.
[0059] Four end portions of the connecting piece 4 are all arranged in a stepped shape and are embedded and welded below the convex edge 3, and its side is welded to the column 2; a corresponding vertical plate 28 is vertically fixedly connected to the inner side of the column support portion 202, and corresponding convex edges 3 are integrally fixedly connected at intervals from top to bottom on the inner side thereof, and the convex edges 3 are vertically fixedly connected to the vertical plate 28.
[0060] Corresponding reinforcing ribs are connected to the middle parts of the four inner side walls of the rectangular installation portion 201 of the column 2 between two adjacent upper and lower convex edges 3, and the reinforcing ribs are vertically supported at the corresponding upper and lower convex edges 3 respectively at the head and tail ends.
[0061] The connection mechanism includes a support base 17 fixedly installed in the sub-groove 10 and correspondingly arranged directly below the filter element 11. At least one embedding hole is recessed downward on the upper end surface of the support base 17. A connecting rod 19 is installed in the embedding hole to move up and down through a corresponding second elastic member 18. The other end of the connecting rod 19 not connected to the second elastic member 18 is connected to the filter element 11; a corresponding pressure gauge 20 is fixedly connected to the bottom of the embedding hole in the middle, and the second elastic member 18 in the embedding hole is fixedly connected to the pressure gauge 20.
[0062] Although the utility model can filter and collect metal chips and cutting fluid in real time, it is easy to cause the accumulation amount of metal chips to exceed the bearing capacity of the filter element 11 after a long time. Personnel need to observe the accumulation situation at any time and remove the metal chips in time, which increases the labor intensity. Therefore, in the utility model, a corresponding pressure gauge 20 is installed in the embedding hole of the support base 17. One end of the second elastic member 18 is fixedly connected to the pressure gauge 20, and the other end is connected to the filter element 11. As materials fall and accumulate to generate pressure, the alarm upper limit value of the pressure gauge 20 is set according to the material quantity. Personnel can process the metal chips in time according to the alarm, reducing the labor intensity.
[0063] The filter element 11 is arranged at an interval from the inner side wall of the sub-tank 10, and the inner side wall of the sub-tank 10 forms a corresponding aggregate tank 22 by welding an annular member 21 with an L-shaped cross section. The aggregate tank 22 is arranged below the gap between the filter element 11 and the sub-tank 10, and the width of the aggregate tank 22 is greater than the width of the gap between the filter element 11 and the sub-tank 10.
[0064] To ensure the up-and-down movement setting of the filter element 11, it needs to be arranged at an interval from the sub-tank 10, which easily causes metal chips to fall from the gap into the liquid guide groove 9 and mix with the filtered cutting fluid. Therefore, in the utility model, a corresponding aggregate tank is formed by welding an annular member 21 with an L-shaped cross section on the inner side wall of the liquid guide groove 9 below the filter element 11, so as to collect the metal chips falling from the gap, effectively preventing them from falling into the filtered cutting fluid again and further ensuring the filtering effect.
[0065] The sub-tank 10 is connected through the bottom of the partition plate being arranged at an interval from the bottom surface of the liquid guide groove 9, and both side edges of the partition plate are fixedly welded to the inner side wall of the liquid guide groove 9. The bottom surface of the liquid guide groove 9 is inclined downward, and a liquid outlet is arranged at the end of its downward inclination, and is connected to the cutting fluid collecting bucket through a corresponding liquid guide pipe and a liquid pumping pump.
