Machine tools, especially large machine tools, can generate large lateral acceleration during operation, so that the machine tools swing and even shift, and hidden mounting hazards exist. In the correlation technique, through the lower margin of expansion bolts fixed lathe, nevertheless need accurate counterpoint when fixed lower margin, the installation degree of difficulty is big, and the installation spends a long time, and it is inconvenient to install.
In order to solve the above problems, referring to fig. 1 to 6, a first embodiment of the present invention provides an adjustable foot mounting mechanism, which is applied to a machine tool 400, particularly a large-sized machine tool and a high-rigidity high-precision machine tool. The foot mounting mechanism includes a base 100, a support base 200, and an adjusting member 300.
The foot mounting mechanism will be described in detail below by taking the machine tool 400 as an example.
Referring to fig. 1 and 2, it can be understood that the base 100 is substantially a rectangular parallelepiped structure, and the cross section of the base is rectangular or square, expansion bolts 120 are respectively connected to four corners of the base 100, and the base 100 is pre-fixed on the ground through the expansion bolts 120, so that the installation is stable and reliable.
Referring to fig. 1 and 2, it can be understood that the base 100 is further provided with a plurality of fixing holes 110, and generally, the fixing holes 110 are provided as screw holes. Specifically, the base 100 is provided with four fixing holes 110, the four fixing holes 110 are divided into two groups and arranged at the left and right ends of the base 100, respectively, the distance between two fixing holes 110 of the same group is smaller than the distance between two fixing holes 110 of different groups, and the centers of the four fixing holes 110 are located on a virtual circle, the center of which is located at the center of the base 100. Therefore, when the supporting base 200 is abutted to the base 100, the supporting base 200 can be supported at the middle position of the base 100, so as to increase the supporting stability of the base 100 to the supporting base 200.
Of course, it is understood that the number and arrangement of the fixing holes 110 are not limited to the above description.
Referring to fig. 1 and 5, it can be understood that the supporting seat 200 includes a main body 210 and a base plate 220, the main body 210 has a substantially cylindrical structure, the base plate 220 has a circular plate-shaped structure or an annular plate-shaped structure, the base plate 220 is connected to a lower end of the main body 210, an outer diameter of the base plate 220 is larger than an outer diameter of the main body 210, a center line of the base plate 220 coincides with a center line of the main body 210, and an upper end of the main body 210 is connected to a bottom of the machine tool 400. When the machine tool 400 is mounted, the support base 200 is supported at the middle position of the base 100, so that the base 100 can provide stable support for the machine tool 400 and the support base 200.
It can be understood that the main body 210 and the base plate 220 can be an integral structure, that is, the integral support seat 200 is directly obtained by casting or turning, the structure is simple, the production is easy, and the structural strength of the integral support seat 200 is good.
It can be understood that the body 210 and the base plate 220 can also be in a split structure, that is, after the body 210 and the base plate 220 are respectively processed by casting or turning, the body 210 and the base plate 220 are welded to obtain the support seat 200, and the split structure is simpler and is easy to produce.
Referring to fig. 1 to 3, it can be understood that the substrate 220 is provided with the void-avoiding portions 221 corresponding to the fixing holes 110 one by one, that is, the positions and the number of the void-avoiding portions 221 all correspond to the fixing holes 110, the void-avoiding portions 221 penetrate through the substrate 220 in the vertical direction, the void-avoiding portions 221 have side walls, the distance between the side walls of the void-avoiding portions 221 and the center line of the fixing holes 110 is greater than the radius of the fixing holes 110, that is, the internal space range of the void-avoiding portions 221 is greater than the fixing holes 110, that is, the projection on the horizontal plane, and the area of the void-avoiding portions 221 is greater than the area of the fixing holes 110. When the machine tool 400 is hoisted, any part of the inner space of the clearance 221 may correspond to the entire fixing hole 110, that is, the entire fixing hole 110 may communicate with the clearance 221. Therefore, in the process of hoisting the machine tool 400, the adjustment range and the fault tolerance range of the machine tool 400 can be enlarged, the supporting seat 200 and the base 100 do not need to be accurately aligned, the hoisting difficulty is effectively reduced, the hoisting time is shortened, and the installation difficulty is reduced.
Referring to fig. 1 to 3, it can be understood that the adjusting member 300 is in a ring structure and is sleeved on the outer periphery of the main body 210, and the adjusting member 300 is rotatably engaged with the main body 210. The adjusting member 300 is located on a side of the base plate 220 facing away from the base 100, that is, the adjusting member 300 is located on an upper side of the base plate 220, the adjusting member 300 is connected with a plurality of first fastening members 310, and the number and the position of the first fastening members 310 correspond to the fixing holes 110. The fixing hole 110 is provided as a screw hole, and the first fastening member 310 is provided as a screw engaged with the screw hole. The first fastening member 310 is inserted into the recess 221 and connected to the fixing hole 110. By screwing the first fastener 310, the adjusting member 300 is pressed against the substrate 220, that is, the adjusting member 300 and the base 100 clamp the substrate 220, so that the supporting seat 200 is stably connected to the base 100, thereby completing the installation of the machine tool 400, reducing the vibration amplitude of the machine tool 400 during the operation process, and improving the machining precision.
It can be understood that after the hoisting operation of the machine tool 400 is completed, that is, the supporting base 200 is loaded on the base 100, the adjusting member 300 can be rotated around the body portion 210 to adjust the position of the first fastening member 310 connected to the adjusting member 300, so that the first fastening member 310 can be connected to the fixing hole 110. Benefit from the regulating part 300 that the activity set up, need not to counterpoint first fastener 310 at lathe 400 hoist and mount in-process, but place after base 100 at lathe 400 stability, carry out position adjustment to first fastener 310 again, effectively reduce the counterpoint degree of difficulty of first fastener 310, reduce the lathe 400 installation degree of difficulty, reduce installation time, easy to assemble.
As shown with reference to fig. 1. It can be understood that, since the upper portion of the rear side of the support seat 200 is the structure of the machine tool 400 itself, the layout of the four fixing holes 110, the clearance portion 221 and the first fastening member 310 benefits from that two fixing holes 110 are respectively arranged at the left end and the right end of the base 100, and the clearance portion 221 and the first fastening member 310 correspond to the fixing holes 110. Therefore, on one hand, the left and right sides of the support base 200 are stressed symmetrically to ensure the connection stability between the support base 200 and the base 100, and on the other hand, the first fastening members 310 can be arranged on the left and right sides of the support base 200 to ensure enough operating space for tightening the first fastening members 310, thereby facilitating the operation. The situation that one first fastening piece 310 is arranged on the rear side of the supporting seat 200 due to the fact that the four first fastening pieces 310 are evenly distributed along the circumferential direction in order to guarantee the stress balance of the supporting seat 200 is avoided.
Referring to fig. 1-4, it will be appreciated that the side near the center of the substrate 220 is defined as the inner side, and the opposite side away from the center of the substrate 220 is defined as the outer side. The space-avoiding portion 221 is a through groove with an outward opening, the through groove penetrates through the substrate 220 along the vertical direction, the inner walls on two sides of the through groove opening are side walls of the through groove, and the inner walls opposite to the opening are bottom walls of the through groove. Generally speaking, the two side walls of the through groove are parallel, the bottom wall of the through groove is a semi-circular arc surface, and the distance between the two side walls of the through groove is greater than the diameter of the fixing hole 110, i.e. L > D0, it is easy to understand that the diameter of the semi-circular arc surface is equal to L. So that the inner space range of the through groove is larger than the fixing hole 110, that is, the area of the through groove is larger than the area of the fixing hole 110 in the projection on the horizontal plane. When the machine tool 400 is hoisted, it is only necessary to make any part of the internal space of the through groove correspond to the entire fixing hole 110, that is, to make the entire fixing hole 110 communicate with the through groove. Therefore, in the process of hoisting the machine tool 400, the adjustment range and the fault tolerance range of the machine tool 400 can be enlarged, the supporting seat 200 and the base 100 do not need to be accurately aligned, the hoisting difficulty is effectively reduced, the hoisting time is shortened, and the installation difficulty is reduced.
It can be understood that, because the opening of the through groove faces outward, when the first fastening member 310 is aligned, an installer can observe the first fastening member 310 from the opening, so that the alignment is facilitated, and the installation difficulty is further reduced.
Referring to fig. 4, it can be understood that the difference between the distance of the two side walls of the through groove and the diameter of the fixing hole 110 is S1, i.e., S1= L-D0, and satisfies: s1 is more than or equal to 10mm and less than or equal to 30mm. The S1 is larger than or equal to 10mm, the internal space range of the through groove can be larger than that of the fixed hole 110, and the adjusting range and the fault-tolerant range in the process of hoisting the machine tool 400 are enlarged; the S1 is less than or equal to 30mm, and the problem of structural strength reduction caused by overlarge hollowed part of the substrate 220 is avoided. For example, S1=20mm, that is, when the center line of the semicircular arc surface of the through groove coincides with the center line of the fixing hole 110, the minimum distance between each of the two side walls of the through groove and the inner wall of the fixing hole 110 is 10mm, and the distance between the semicircular arc surface and the inner wall of the fixing hole 110 is 10mm, so that the machine tool 400 has a sufficient adjustment range and a sufficient fault tolerance range when being hoisted, and the hoisting difficulty is reduced. Of course, the value of S1 may also be 10mm, 15mm, 25mm, 30mm, or the like.
Referring to fig. 6, it can be understood that the clearance 221 is provided as a through hole penetrating the substrate 220 in a vertical direction, and the diameter of the through hole is larger than that of the fixing hole 110, i.e., D1 > D0. Generally, the center line of the through hole and the center line of the fixing hole 110 intersect the same virtual circle. So that the inner space range of the through hole is larger than the fixing hole 110, that is, the area of the through hole is larger than the area of the fixing hole 110 in a projection on a horizontal plane. When the machine tool 400 is hoisted, it is only necessary to make any part of the inner space of the through hole correspond to the entire fixing hole 110, that is, to make the entire fixing hole 110 communicate with the through hole. Therefore, in the process of hoisting the machine tool 400, the adjustment range and the fault-tolerant range of the machine tool 400 can be enlarged, the supporting seat 200 and the base 100 do not need to be accurately aligned, the hoisting difficulty is effectively reduced, the hoisting time is shortened, and the installation difficulty is reduced.
Referring to fig. 6, it can be understood that the difference between the diameter of the through hole and the diameter of the fixing hole 110 is S2, i.e., S2= D1-D0, and satisfies: s2 is more than or equal to 10mm and less than or equal to 30mm. The S2 is larger than or equal to 10mm, the internal space range of the through hole can be larger than that of the fixed hole 110, and the adjusting range and the fault-tolerant range in the process of hoisting the machine tool 400 are enlarged; the S2 is less than or equal to 30mm, and the problem of structural strength reduction caused by overlarge hollowed part of the substrate 220 is avoided. For example, S2=20mm, that is, when the center line of the through hole coincides with the center line of the fixing hole 110, the distance from the inner wall of the through hole to the inner wall of the fixing hole 110 is 10mm, so that the machine tool 400 has a sufficient adjustment range and a sufficient fault tolerance range when being hoisted, and the hoisting difficulty is reduced. Of course, the value of S2 may also be 10mm, 15mm, 25mm, 30mm, or the like.
It will be appreciated that, in general, the bottom of machine 400 has at least four feet mounted to the bottom of machine 400 at four angular positions. After the hoisting is completed, the levelness of the machine tool 400 needs to be adjusted by adjusting four ground feet.
Referring to fig. 1 to 3, it can be understood that the support base 200 is further coupled with an adjustment screw 230 and a second fastening member 240. Wherein, the outer peripheral wall of the adjusting screw sleeve 230 is provided with screw threads, and the inner peripheral wall of the adjusting screw sleeve 230 is a smooth surface. The adjusting screw 230 is screwed into the screw hole of the machine tool 400, and generally, the center line of the adjusting screw 230 coincides with the center line of the body portion 210 of the support seat 200, and the lower end of the adjusting screw 230 abuts against the upper end surface of the body portion 210. The second fastening member 240 is a screw, the body portion 210 is provided with a screw hole matched with the second fastening member 240 (i.e. the screw), the outer diameter of the rod portion of the second fastening member 240 is smaller than the inner diameter of the inner hole of the adjusting screw sleeve 230, the lower end of the second fastening member 240 penetrates through the adjusting screw sleeve 230 and is in threaded connection with the screw hole of the body portion 210, after the second fastening member 240 is screwed, the head of the second fastening member 240 abuts against the upper end of the adjusting screw sleeve 230, i.e. the upper end of the second fastening member 240 is limited at the upper end of the adjusting screw sleeve 230, so that the support seat 200 is connected to the bottom of the machine tool 400 in advance, and the connection is stable and reliable, and the connection structure is simple and easy to operate.
Referring to fig. 1 to 3, it can be understood that the adjusting screw sleeve 230 is further screwed with an adjusting nut 250, and the adjusting nut 250 abuts against an end surface of the machine tool 400 on a side away from the support seat 200. After the hoisting is finished, when the height of the machine tool 400 from the ground needs to be adjusted, the adjusting nut 250 is loosened, the adjusting screw sleeve 230 is screwed, the height of the corresponding angle position of the machine tool 400 from the ground can be adjusted, and the adjusting nut 250 is screwed after the adjustment is finished. Therefore, the height of the four corners of the machine tool 400 from the ground can be adjusted by respectively operating the adjusting threaded sleeves 230 and the adjusting nuts 250 of the four ground feet, so that the overall levelness of the machine tool 400 is adjusted, and the machine tool is convenient to operate and adjust.
In a second aspect, the invention further provides a high-rigidity and high-precision machine tool device, which comprises the foundation mounting mechanism of any one of the above embodiments. Specifically, taking the machine tool 400 as an example, the aforementioned foot attachment mechanisms are attached to the four corners of the machine tool 400. Because set up on the base plate 220 of supporting seat 200 and keep away empty portion 221, and the distance of the lateral wall of keeping away empty portion 221 to the central line of the fixed orifices 110 of base 100 is greater than the radius of fixed orifices 110, the inner space scope of keeping away empty portion 221 is greater than fixed orifices 110 promptly, therefore, only need make when hoisting machine tool 400 keep away empty portion 221 arbitrary part with whole fixed orifices 110 correspond in vertical direction can, need not accurate counterpoint, increase adjustment space and the fault-tolerant space of hoist and mount in-process, effectively reduce the hoist and mount degree of difficulty.
