Description

Technical Field

[0001] The invention relates to the technical field of shock absorbing structures, and in particular to a shock absorbing structure for improving the stability of a machine tool. Background Art

[0002] Machine tools refer to machines that manufacture machines and machinery. Machine tools play a major role in the modernization of the national economy. Lathes are machine tools that mainly use turning tools to turn rotating workpieces. Drills, reamer drills, reamers, taps, dies and knurling tools can also be used on lathes for corresponding processing.

[0003] However, most of the machine tools currently produce large vibrations when in use.

The shock-absorbing structure used in current machine tools has the problems of simple structure, weak shock-absorbing effect, and low shock-absorbing stability of the machine tools. The vibration frequency generated will also change according to the different operating states of the machine tools.

[0015] The present invention has at least the following beneficial effects: (1) This scheme provides an adjustable shock-absorbing mechanism. The damping rod and the second spring can be used to absorb the vibration transmitted from the support plate to the inside of the mounting plate. The position of the rotating disk on the side wall of the damping rod can be adjusted by rotating the adjusting member, so that the compression degree of the second spring on the top of the rotating disk can be adjusted, thereby achieving the effect of adjusting the shock-absorbing degree. The shock-absorbing effect can be adjusted according to the operating state and vibration frequency of the machine tool, so that the machine tool can operate more stably under different states. (2) This scheme sets a circulation mechanism. When the movable plate moves inside the liquid storage chamber, the damping liquid inside the liquid storage chamber flows through the through hole when the movable plate slides inside the liquid storage chamber. During this process, the circulating damping liquid pushes the baffle plate upward so that the baffle plate is located inside the movable groove, so that the damping liquid can quickly flow from the bottom of the movable plate to the top of the movable plate. When the movable plate is reset under the support of the second external spring, the damping liquid flows from the top of the movable plate to the bottom of the movable plate through the through hole again. During this process, the flowing damping liquid will contact the fixed plate and cooperate with the force of the torsion spring to drive the baffle plate to reset. After the baffle plate is reset, the damping liquid cannot flow through the through hole, and will flow to the bottom of the movable plate through the circulation groove inside the movable groove. Since the circulation groove is small, the damping liquid will flow to the bottom of the movable plate more slowly. The damping liquid at the bottom of the movable plate inside the liquid storage chamber can flow to the top of the movable plate faster, while the damping liquid at the top of the movable plate can flow to the bottom of the movable plate more slowly. It can quickly absorb vibration and slowly reset at the same time, thereby achieving better damping and shock absorption effect. (3) In this scheme, a sealing member can be provided to seal the mounting hole. By providing the mounting hole, the damping liquid inside the liquid storage chamber can be easily replaced, so that the damping rod always maintains a stable damping effect; (4) This solution can be used to support the support plate by setting an electric push rod, so that the sliding frame can be more conveniently pulled out from the inside of the base.

[0019] See also Figure 1-Figure 8 The present invention provides a shock absorbing structure for improving the stability of a machine tool, comprising: Machine tool 1; A shock-absorbing base plate, the shock-absorbing base plate is installed at the bottom of the machine tool 1; The shock-absorbing base plate includes a base 2 and a support plate 22, and the support plate 22 is movably connected inside the base 2; The support mechanism is installed inside the shock-absorbing base plate. The support mechanism is located between the inner wall of the base 2 and the bottom of the support plate 22. The support plate 22 is composed of two contact layers 221 and a shock-conducting layer 222. The contact layer 221 is made of ACF artificial cartilage bionic energy-absorbing material, which has nonlinear viscoelasticity. It is soft and buffers external forces at low speed and light load, and is tough and reliable at high speed and heavy load. It is used to absorb and conduct vibrations, and can reduce the vibrations generated by the operation of the machine tool 1 to a certain extent. The shock-conducting layer 222 is made of aluminum alloy, and is used to quickly conduct the vibrations generated by the operation of the machine tool 1, so that the bottom shock-absorbing mechanism can perform shock absorption faster; A moving component, the moving component is installed inside the shock-absorbing base plate, and an adjusting shock-absorbing mechanism for shock absorption is arranged inside the moving component.

The sliding frame 3 is slidably connected to the inside of the base 2 , and the toggle member 31 is fixedly installed on one side of the sliding frame 3 .

[0020] In some embodiments, see Figure 4 , Figure 5 The damping mechanism includes a mounting plate 35, a damping rod 36, an adjusting member 37, a rotating disk 38, and a second spring 34. A first connecting shaft 39 is fixedly installed at one end of the damping rod 36, and a second connecting shaft 310 is fixedly installed at the other end of the damping rod 36. The first connecting shaft 39 is rotatably connected to the inside of the sliding frame 3, and the second connecting shaft 310 is rotatably connected to the inside of the mounting plate 35. The adjusting member 37 is movably connected to the side wall of the damping rod 36 through a threaded structure, and the rotating disk 38 is rotatably connected to the top of the adjusting member 37. The rotating disk 38 is located on the side wall of the damping rod 36. The second spring 34 is fixedly installed between the top of the rotating disk 38 and the bottom of the mounting plate 35. The second spring 34 is located on the side wall of the damping rod 36. The mounting plate 35 is slidably connected to the inside of the support plate 22. The machine tool 1 is installed on the top of the support plate 22. The mounting plate 35 is in contact with the support plate 22. The damping rod 36 and the second spring 34 are provided to absorb the vibration transmitted from the support plate 22 to the inside of the mounting plate 35, thereby achieving the effect of damping the machine tool 1 on the top of the support plate 22. An adjusting member 37 is provided to adjust the position of the rotating disk 38 on the side wall of the damping rod 36 by rotating the adjusting member 37, so that the compression degree of the second spring 34 on the top of the rotating disk 38 can be adjusted, thereby achieving the effect of adjusting the damping degree. The damping effect can be adjusted according to the operating state and vibration frequency of the machine tool 1, so that the machine tool 1 can operate more stably under different states. The rotating axes of the first connecting shaft 39 and the second connecting shaft 310 are vertical in the spatial state, so that the damping rod 36 can adapt to multi-directional offset movement.

[0021] In some embodiments, see Figure 4 , Figure 5The damping rod 36 includes a fixed rod 361, a movable rod 362 and a movable plate 365. A liquid storage chamber 364 is provided inside the fixed rod 361. The movable plate 365 is slidably connected inside the liquid storage chamber 364. The movable rod 362 is fixedly installed on the top of the movable plate 365. A through hole 366 is provided inside the movable plate 365. A sealing ring 363 is fixedly installed on the top of the fixed rod 361. The liquid storage chamber 364 is filled with damping liquid. The sealing ring 363 can be used to seal the connection between the movable rod 362 and the fixed rod 361.

[0022] In some embodiments, see Figure 4 , Figure 5 A mounting hole 367 connected to the liquid storage chamber 364 is provided on one side of the fixing rod 361, and a sealing member 368 is installed inside the mounting hole 367. The sealing member 368 can be used to seal the mounting hole 367, and the mounting hole 367 can be provided to facilitate replacement of the damping fluid inside the liquid storage chamber 364.

[0023] In some embodiments, see Figure 5 , Figure 7The through hole 366 is a tapered hole, and the top diameter of the through hole 366 is smaller than the bottom diameter. By setting the through hole 366 as a tapered hole, a circulation mechanism is arranged inside the through hole 366, and the circulation mechanism includes a rotating shaft 61, a baffle 63, a contact member 64 and a fixed plate 65. A movable groove 6 is opened on the inner wall of the through hole 366, and the rotating shaft 61 is rotatably connected to the inside of the movable groove 6 through a torsion spring. One end of the baffle 63 is fixedly mounted on the side wall of the rotating shaft 61, and the contact member 64 is fixedly mounted on the other end of the baffle 63. The fixed plate 65 is fixedly mounted on the baffle 63. On one side, a flow groove 62 is provided inside the movable groove 6, and the flow groove 62 is connected with the through hole 366, and the flow groove 62 passes through the movable plate 365. The baffle 63 can be rotated inside the through hole 366 by setting the rotating shaft 61, and the baffles 63 on both sides can be closed automatically by setting the torsion spring. The baffle 63 is installed obliquely inside the through hole 366. By setting the flow mechanism, when the movable plate 365 moves inside the liquid storage chamber 364, the damping liquid inside the liquid storage chamber 364 flows when the movable plate 365 slides inside the liquid storage chamber 364. The damping fluid circulates through the through hole 366. During this process, the damping fluid pushes the baffle 63 upward, so that the baffle 63 is located inside the movable groove 6, so that the damping fluid can quickly flow from the bottom of the movable plate 365 to the top of the movable plate 365. When the movable plate 365 is reset under the support of the external second spring 34, the damping fluid flows from the top of the movable plate 365 to the bottom of the movable plate 365 through the through hole 366 again. During this process, the flowing damping fluid contacts the fixed plate 65, and cooperates with the force of the torsion spring to drive the baffle 63 to reset. After resetting, the damping fluid cannot flow through the through hole 366, and will flow to the bottom of the movable plate 365 through the flow groove 62 inside the movable groove 6. Since the flow groove 62 is small, the damping fluid will flow to the bottom of the movable plate 365 more slowly, and the damping fluid at the bottom of the movable plate 365 inside the liquid storage chamber 364 can flow to the top of the movable plate 365 faster, while the damping fluid at the top of the movable plate 365 can flow to the bottom of the movable plate 365 more slowly, so that the vibration is quickly absorbed and slowly reset, so that the damping shock absorption effect can be better.

[0024] In some embodiments, see Figure 4 , Figure 5 The sliding frame 3 and the mounting plate 35 are both rotatably connected with ball bearings 32, and a spring telescopic rod 33 is fixedly installed between the sliding frame 3 and the ball bearings 32 inside the mounting plate 35. The spring telescopic rod 33 is composed of a telescopic rod and a spring, and the telescopic rod is composed of one rod sliding inside another rod. By setting the spring telescopic rod 33, it can be used to support the sliding frame 3 and the mounting plate 35 bracket.

[0025] In some embodiments, see Figure 3 , Figure 4An elastic plate 21 is fixedly installed inside the base 2, and the elastic plate 21 is located between one side of the support plate 22 and the inner wall of the base 2. A first spring 23 is fixedly installed on one side of the elastic plate 21. The elastic plate 21 can be used to support the side of the support plate 22, thereby avoiding support buffering on the support plate 22.

[0026] In some embodiments, see Figure 4 The supporting mechanism includes an electric push rod 4 and a supporting pad 41. The electric push rod 4 is fixedly installed on the inner wall of the base 2, and the supporting pad 41 is fixedly installed on the output end of the electric push rod 4. By setting the electric push rod 4, it can be used to support the supporting plate 22, so that the sliding frame 3 can be more conveniently pulled out from the inside of the base 2.

[0027] In some embodiments, see Figure 2 , Figure 6 A mounting cavity 5 is provided inside the base 2, a third spring 51 is fixedly installed on the inner wall of the mounting cavity 5, a clamping block 52 is fixedly installed on one end of the third spring 51, and a clamping groove 53 that matches the clamping block 52 is provided on one side of the sliding frame 3. The third spring 51 can be used to support the clamping block 52, and the sliding frame 3 inserted into the base 2 can be clamped and fixed by clamping the clamping block 52 into the clamping groove 53.

[0028] The working process and principle of the present invention are as follows: when the shock absorption effect needs to be adjusted during use, the support plate 22 is supported by the operation of the electric push rod 4, and then the sliding frame 3 is pulled out by the toggle member 31, and then the adjusting member 37 is rotated according to the specific situation of the machine tool 1, and the position of the rotating disk 38 on the side wall of the damping rod 36 is adjusted by rotating the adjusting member 37, so that the compression degree of the second spring 34 at the top of the rotating disk 38 can be adjusted, so as to achieve the effect of adjusting the shock absorption degree, so that the shock absorption effect can be adjusted according to the operating state and vibration frequency of the machine tool 1, so that the machine tool 1 can operate more stably under different states, and at the same time, the damping fluid inside the damping rod 36 can be replaced by pulling out the sliding frame 3, and then the sliding frame 3 is inserted again and the electric push rod 4 is reset, thereby playing a shock absorption effect, so that the damping rod 36 always maintains a stable damping effect, and when the movable plate 365 moves inside the liquid storage chamber 364, the damping fluid inside the liquid storage chamber 364 passes through the through hole 36 when the movable plate 365 slides inside the liquid storage chamber 364. 6, during which the damping fluid will push the baffle 63 upward, so that the baffle 63 is located inside the movable groove 6, so that the damping fluid can quickly flow from the bottom of the movable plate 365 to the top of the movable plate 365. When the movable plate 365 is reset under the support of the external second spring 34, the damping fluid will flow from the top of the movable plate 365 to the bottom of the movable plate 365 through the through hole 366 again. During this process, the flowing damping fluid will contact the fixed plate 65, and cooperate with the force of the torsion spring to drive the baffle 63 to reset. After the damping fluid is in the position, it cannot flow through the through hole 366, and will flow to the bottom of the movable plate 365 through the flow groove 62 inside the movable groove 6. Since the flow groove 62 is smaller, the damping fluid will flow to the bottom of the movable plate 365 more slowly, and the damping fluid at the bottom of the movable plate 365 inside the liquid storage chamber 364 can flow to the top of the movable plate 365 faster, and the damping fluid at the top of the movable plate 365 can flow to the bottom of the movable plate 365 more slowly, quickly absorbing vibrations and slowly resetting, thereby achieving better damping and shock absorption effects.
