Description

TECHNICAL FIELD

[0001] The application relates to the field of machine tools, in particular to a self-adaptive shockproof base of a numerical control double-column vertical lathe. BACKGROUND

[0002] The numerical control double-column vertical lathe is a precision machining equipment widely used in the manufacturing field, which generates a large cutting force and vibration during operation and needs stable ground support. Such machine tools usually require very high stability and shock resistance to ensure the precision of the machined parts. Traditional machine tool bases usually have certain limitations. When encountering external vibration or uneven ground, they are difficult to eliminate the negative effects brought by external vibration or uneven ground, which not only affects the machining precision of the numerical control lathe, but also may cause rapid wear or damage of the equipment.

[0003] With the development of science and technology, relevant technical personnel in the field have also optimized the technical means for shockproof of numerical control lathes.

However, in actual use, since the above-mentioned device directly contacts the ground through the mounting plate, and then supports the machining jig on the support plate through the support rod, vertical spring, a plurality of compression spring one and compression spring two connected with the mounting plate limiting, that is, the machining jig and the like are actually supported by the hard contact between the mounting plate and the ground, the flatness and contact effect between the ground and the mounting plate greatly affect the stability of the machine tool as a whole. Although the mounting plate can be directly limited on the ground by means of expansion screws to ensure the relative stability during use, in the case where the flatness of the ground itself is not high and has a certain slope, the machine tool as a whole is easily inclined, so that the machining jig and the workpiece on the machine tool are in an abnormal stress state in the initial state, thereby causing the problem of expanding the vibration amplitude during machining.

Detailed Implementation

[0034] The following is in conjunction with the appendix Figure 1 To be continued Figure 9 The embodiments of the present invention will be described in detail below.

[0035] This application discloses an adaptive anti-vibration base for a CNC double-column vertical lathe. This application is mainly used in the process of machining workpieces on a CNC double-column vertical lathe. In terms of technical effect, through the cooperation between the supporting frame and the connecting base, the lathe and the connecting base can adaptively adjust their own posture according to different ground conditions, ensuring that the lathe remains parallel to the horizontal plane before installation and use. This avoids the problem of abnormal vibration caused by uneven installation posture of the lathe, and achieves the effect of adaptive anti-vibration according to different ground conditions.

[0036] Example 1: Refer to Figure 1 As shown, a CNC double-column vertical lathe adaptive anti-vibration base includes a support frame 1, with a connecting base 10 for corresponding connection with a CNC lathe connected to the upper limit of the support frame 1. An anti-vibration component 2 is provided between the support frame 1 and the connecting base 10. In use, the support frame 1 is placed on the ground, and the lathe is positioned on the connecting base 10. The anti-vibration component 2 is used to adjust and control the connecting base 10 and the CNC lathe, ensuring that the CNC lathe is initially level, avoiding vibration caused by abnormal load due to the lathe's own tilt. At the same time, the anti-vibration component 2 buffers vibrations during lathe machining, preventing vibration from affecting the machining accuracy of the workpiece, thus achieving the effect of anti-vibration and vibration damping for the CNC lathe.

[0037] Reference Figure 2As shown, namely for shock absorption shock absorbing assembly 2; specifically, the shock absorbing assembly 2 includes:

[0038] Swing guide rod 20, provided with a plurality of and symmetrically distributed on both sides of the connecting base 10, swing guide rod 20 away from the connecting base 10 one end of the slip set in the support frame 1.

[0039] Connecting guide rod 21, provided in the lower end of the connecting base 10, the upper limit set in the adjusting support plate 22 between the support frame 1 and the connecting base 10, the adjusting support plate 22 is connected with the support frame 1 by connecting piece 23, the posture of the adjusting support plate 22 relative to the ground is adjusted by connecting piece 23, so that the whole lathe always keeps horizontal state.

[0040] Buffer spring 24, symmetrically arranged on both sides of the connecting base 10, and the other end is connected with the support frame 1, for buffering shock absorption.

[0041] In use, the support frame 1 is limited on the ground, and the numerical control lathe is limited on the connecting base 10, the posture of the adjusting support plate 22 relative to the ground is adjusted by connecting piece 23, so that the whole lathe always keeps horizontal state, to realize the effect of self adapting to the posture of the lathe according to the ground state, effectively avoid the vibration caused by the skew state of the lathe after installation, realize the effect of shock absorption, and the vibration generated during the processing of the lathe is buffered and absorbed by the deformation of the buffer spring 24 between the connecting base 10 and the support frame 1, to avoid the problem of large vibration amplitude of the whole equipment.

[0042] Referring to Figure 3 As shown, namely for driving the connecting base 10 and the lathe adjusting connecting piece 23; specifically, the connecting piece 23 includes a plurality of connecting pipes 230 arranged on the adjusting support plate 22, the connecting pipe 230 is axially provided with a sliding support rod 231, the sliding support rod 231 is provided with a connecting plate 232, and the connecting plate 232 and the support frame 1 are connected with a vertical spring 233. By adjusting the distance between the sliding support rod 231 and the connecting pipe 230 on the adjusting support plate 22 relative to the support frame 1, the adjusting support plate 22 is deflected as the connecting guide rod 21, the effect of self adapting to the adjusting support plate 22, the connecting base 10 and the whole lathe is realized, in the initial state, the sliding support rod 231 and the connecting plate 232 are driven by the connected vertical spring 233, and always have the tendency of upward sliding extension.

[0043] When in use, after the lathe is positioned on the connecting base 10, the lathe and the connecting base 10 are driven to apply pressure downward under the influence of their own gravity, to drive the connecting guide rod 21, the adjusting support plate 22 and all the connecting guide pipes 230 to move downward, and after the connecting base 10 contacts the connecting horizontal plate 232, the connecting horizontal plate 232 and the sliding support rod 231 are also driven to slide downward synchronously, and the connected vertical springs 233 are driven to be compressed, and after the connecting guide pipes 230 move downward and contact the supporting frame 1, the connecting horizontal plate 232 and the sliding support rod 231 are further driven to move downward under the driving of the gravity of the lathe and the connecting base 10, until the connecting horizontal plate 232 abuts on the connecting guide pipes 230, at which time the vertical springs 233 are further compressed.

[0044] Based on the above, after the vibration generated during the machining of the lathe is transmitted to the vertical springs 233 and the buffer springs 24, the vertical springs 233 and the buffer springs 24 are driven to elastically deform, and during the deformation of the vertical springs 233 and the buffer springs 24, a part of the applied extrusion force of the vibration is absorbed and stored, thereby prolonging the action time of the impact force. According to the law of momentum, the longer the action time, the smaller the impact force. The elastic deformation of the vertical springs 233 and the buffer springs 24 reduces the impact force generated by the vibration, thereby reducing the damage to the lathe equipment and improving the stability and service life of the lathe equipment.

[0045] Further, as shown in Figure 4 in order to improve the stability during use, the lower end of the connecting guide pipe 230 is connected with a suction cup 234 made of flexible material. The suction cup 234 is preferably made of high-elastic wear-resistant material, such as polyurethane material. After the connecting guide pipe 230 and the suction cup 234 are driven to move downward by the gravity of the lathe and the connecting base 10 and abut on the supporting frame 1, the suction cup 234 first abuts tightly on the supporting frame 1 and then elastically deforms. After the air between the suction cup 234 and the supporting frame 1 is exhausted, the suction cup 234 is adsorbed on the supporting frame 1 due to the pressure difference between the inside and outside of the suction cup 234, thereby achieving the effect of improving the stability of the connecting guide pipe 230 and the connecting base 10 during use.

[0046] As shown in Figure 4 in order to improve the stability during use, the lower end of the connecting guide pipe 230 is connected with a suction cup 234 made of flexible material. The suction cup 234 is preferably made of high-elastic wear-resistant material, such as polyurethane material. After the connecting guide pipe 230 and the suction cup 234 are driven to move downward by the gravity of the lathe and the connecting base 10 and abut on the supporting frame 1, the suction cup 234 first abuts tightly on the supporting frame 1 and then elastically deforms. After the air between the suction cup 234 and the supporting frame 1 is exhausted, the suction cup 234 is adsorbed on the supporting frame 1 due to the pressure difference between the inside and outside of the suction cup 234, thereby achieving the effect of improving the stability of the connecting guide pipe 230 and the connecting base 10 during use.

[0047] When the lathe applies a lateral tangential force to the connecting base 10, the connecting base 10 is driven to slide the swing guide rod 20 to one side, the buffer spring 24 on the side where the connecting base 10 moves is compressed under force, and the buffer spring 24 on the other side of the connecting base 10 is stretched under force. The lateral sliding of the connecting base 10 also synchronously drives the limiting sleeve 210, the ball shaft 211 and the adjusting support plate 22 to slide synchronously, thereby driving all the vertical springs 233 to be tilted towards the direction where the connecting base 10 slides laterally. At this time, the vertical springs 233 on the side where the connecting base 10 moves are tilted and compressed, and the vertical springs 233 on the other side of the connecting base 10 are tilted and stretched. When the connecting base 10 is driven to slide laterally to the other side, the states of the buffer springs 24 and the vertical springs 233 on both sides of the connecting base 10 are reversed. In this way, the vibration during lathe processing is adaptively buffered.

[0048] Referring to Figure 4 As shown, the supporting frame 1 is provided with a guide through slot 25 corresponding to the swing guide rod 20, so as to allow the swing guide rod 20 to be driven by the connecting base 10 to slide in the vertical direction for adjustment, and at the same time limit the sliding path of the swing guide rod 20 to avoid large deflection of the lathe and the connecting base 10 as a whole.

[0049] Referring to Figure 4 In order to buffer the vibration during lathe processing by the buffer spring 24, the same driven slider 240 is symmetrically connected with an extension block 26 inserted on the supporting frame 1 on both sides, and the supporting frame 1 is also provided with a limiting sliding groove 260 corresponding to the extension block 26 and communicating with the vertical sliding groove 241. The limiting sliding groove 260 limits the displacement of the extension block 26, and the extension block 26 limits the displacement of the driven slider 240, so that the driven slider 240 and the extension block 26 as a whole are only allowed to slide along the vertical sliding groove 241, so that when the lateral tangential force of the vibration is applied to the connecting base 10, the displacement of the buffer spring 24 connected with the driven slider 240 and the extension block 26 is limited by the driven slider 240 and the extension block 26, so that the buffer spring 24 is driven by the connecting base 10 to stretch or contract.

[0050] Further, referring to Figure 4 In order to avoid the close fit of the supporting frame 1 with the driven slider 240, the swing guide rod 20 and the extension block 26, and to avoid hindering the movement or deflection of the driven slider 240, the swing guide rod 20 and the extension block 26, the vertical sliding groove 241, the guide through slot 25 and the limiting sliding groove 260 are all larger than the corresponding sizes of the driven slider 240, the swing guide rod 20 and the extension block 26, so that the connecting base 10 as a whole is allowed to have a certain degree of deflection adjustment.

[0051] Referring to Figure 4As shown, in order to adjust the posture of the connecting base 10 and the lathe as a whole according to different ground conditions, the connecting guide rod 21 comprises a limiting sleeve 210 connected with the connecting base 10, a ball shaft 211 connected with the adjusting support plate 22 is inserted in the limiting sleeve 210, and the ball head end of the ball shaft 211 is limited to pass through the adjusting support plate 22 to allow the adjusting support plate 22 to be deflected and adjusted with the ball head end of the ball shaft 211 as the shaft.

[0052] In use, since the vertical sliding groove 241, the guide through groove 25 and the limiting sliding groove 260 are all used to guide the sliding of the driven sliding block 240, the swing guide rod 20 and the extension block 26 in the vertical direction, and the vertical sliding groove 241, the guide through groove 25 and the limiting sliding groove 260 are all larger than the size of the corresponding driven sliding block 240, swing guide rod 20 and extension block 26, so that the connecting base 10 as a whole allows a certain range of deflection adjustment, and the lathe and the connecting base 10 are guided to slide vertically downward in the initial stage due to the influence of their own gravity, and after the connecting guide pipe 230 and the suction cup 234 are in contact with the supporting frame 1.

[0053] At this time, if the lower side of the supporting frame 1 is a normal flat ground, the connecting guide pipes 230 and the suction cups 234 are simultaneously driven to be attached to the supporting frame 1, so that the suction cups 234 are adsorbed on the supporting frame 1, and if the sliding amplitudes of the sliding support rods 231 relative to the connected connecting guide pipes 230 are the same, the amplitudes of the compression of the vertical springs 233 are also the same, and the vertical springs 233 normally buffer the vibration during lathe machining.

[0054] If the lower side of the supporting frame 1 is a ground with a certain slope (usually a relatively flat ground due to ground micro-deformation or ground subsidence), the supporting frame 1 is in an inclined state in the initial stage, and during the process of driving the adjusting support plate 22, the connecting guide pipes 230 and the suction cups 234 to move downward, before the suction cups 234 and the connecting guide pipes 230 completely contact the supporting frame 1, the adjusting support plate 22, the limiting sleeve 210, the ball shaft 211, the connecting base 10 and the lathe as a whole are still in a state of vertical downward movement, and after one of the suction cups 234 and the connecting guide pipes 230 contact the supporting frame 1 (generally the suction cup 234 and the connecting guide pipe 230 close to the higher side of the inclined supporting frame 1), due to the inclination of the supporting frame 1, the connecting base 10, the swing guide rod 20 and the lathe as a whole still have a downward sliding tendency due to their own gravity, and the downward movement of the lathe and the connecting base 10 and the supporting frame 1 form a certain range of deflection and downward sliding state.

[0055] Adjusting the connecting pipes 230 and the suction cups 234 on the adjusting support plate 22 will present that the connecting pipes 230 and the suction cups 234 on one side will first contact the higher side of the supporting frame 1, and at the same time, the suction cups 234 on the side will be completely adsorbed on the supporting frame 1, the connecting horizontal plate 232 on the side will slide to the state of abutting against the limiting sleeve 210, the connecting pipes 230 and the suction cups 234 on the other side will later contact the lower side of the supporting frame 1, and the suction cups 234 will not be completely adsorbed on the supporting frame 1, so that the adjusting support plate 22 will be deflected by the ball head end of the ball shaft 211, at this time, the lathe, the connecting base 10, the adjusting support plate 22 and the swing guide rod 20 will be relatively inclined to the supporting frame 1, and at the same time, will be relatively parallel to the horizontal plane, so as to complete the effect of self-adaptive adjustment of the posture of the lathe according to the ground state, thereby effectively avoiding the vibration problem caused by the inclination of the lathe.

[0056] Further, referring to FIG. 2, the connecting base 10 is internally hollowed to form an installation cavity, and a shock absorber 27 is connected in the installation cavity. Figure 4 Further, referring to FIG. 2, the connecting base 10 is internally hollowed to form an installation cavity, and a shock absorber 27 is connected in the installation cavity.

[0057] Further, referring to FIG. 2, the connecting base 10 is internally hollowed to form an installation cavity, and a shock absorber 27 is connected in the installation cavity. Figure 5 Further, referring to FIG. 2, the connecting base 10 is internally hollowed to form an installation cavity, and a shock absorber 27 is connected in the installation cavity.

[0058] Further, referring to FIG. 2, the connecting base 10 is internally hollowed to form an installation cavity, and a shock absorber 27 is connected in the installation cavity.

[0059] When the lathe works, the vibration is transmitted to the connecting base 10, so that the pressure ball 272 in the connecting sleeve 270 is stressed, the compression spring 273 is compressed, and the sliding connecting rod 271 moves downward. At this time, the driven swing rod 274 will swing around the hinge point between the bottom of the sliding connecting rod 271, and the counterweight ball 275 will generate a reverse force on the driven swing rod 274 due to its own gravity. In this way, part of the vibration energy is offset, and the force borne by the buffer spring 24 and the vertical spring 233 is shared through the swing of the gravity ball and the driven swing rod 274, reducing the stress deformation frequency of the buffer spring 24 and the vertical spring 233, effectively avoiding the premature wear and fatigue of the buffer spring 24 and the vertical spring 233 due to excessive stress, and making the shock absorption performance of the entire self-adaptive shock absorption base more stable and durable.

[0060] In addition, in order to further improve the shock absorption effect of the gravity ball, the pressure ball 272 slides against the compression spring 273. When the pressure ball 272, the sliding connecting rod 271, the driven swing rod 274 and the gravity ball are driven upward, the pressure ball 272 has a tendency to separate upward from the compression spring 273. At this time, the pressure ball 272, the sliding connecting rod 271, the driven swing rod 274 and the gravity ball are affected by their own downward gravity, so that the pressure ball 272 and the compression spring 273 maintain a dynamic abutting relationship. This dynamic relationship can more accurately adjust the buffering degree according to the change of vibration and respond in time under different intensity of vibration.

[0061] Example Three: Referring to Figure 8 As shown in the drawings, on the basis of example one and example two, when on a sloping ground, due to the deflection and inclination of the connecting base 10 and the lathe relative to the supporting frame 1, the buffer springs 24 on both sides of the connecting base 10 are also subjected to a certain relative torsional force and tensile force due to the deflection and inclination of the connecting base 10, that is, the buffer springs 24 on both sides of the connecting base 10 are stretched and relatively twisted in the initial stage, and at this time, the stress applied to the connecting base 10 by the twisted buffer springs 24 is relatively balanced with the driving force of the lathe and the connecting base 10 under the gravity downward.

[0062] Based on the above, after the vibration generated by the lathe processing forms a vertical tangential force applied to the connecting base 10, the buffer springs 24 are further stretched (that is, the balance of the buffer springs 24 and the connecting base 10 as a whole is broken), and after the vertical tangential force applied by the lathe is reduced, the two buffer springs 24 that are stretched and twisted will shrink and rotate to a certain extent in order to absorb the vibration energy generated by the vibration of the lathe, thereby achieving the effect of further buffering the vibration during the lathe processing.

[0063] Working time: the first step, the supporting frame 1 is placed on the ground, the numerical control lathe is fixed on the connecting base 10, the lathe and the connecting base 10 are integrally moved downward under the action of their own gravity, and the shockproof assembly 2 is driven to adjust the posture of the connecting base 10 relative to the supporting frame 1, so that the connecting base 10 and the lathe are kept in parallel with the horizontal plane.

[0064] The second step: after the self-adaptive leveling of the connecting base 10 and the lathe is completed, the vibration generated in the machining process of the lathe is transmitted to the buffer springs 24 and the vertical springs 233, the buffer springs 24 and the vertical springs 233 are driven to elastically deform, the vibration energy in the machining of the lathe is absorbed through the deformation of the buffer springs 24 and the vertical springs 233, so that the effect of buffering vibration is realized.

[0065] The third step: after the leveling of the connecting base 10 and the lathe is completed on the ground with slope, due to the deflection of the connecting base 10 relative to the supporting frame 1, the buffer springs 24 connected therewith are twisted, so that the trend force of rotating the connecting base 10 and the lathe to be parallel with the bottom of the supporting frame 1 is applied to the connecting base 10 and the lathe as a whole in the initial stage, so that the effect of preventing the vibration of the lathe is realized.
