Description
本發明是有關於一種加工機械，特別是指一種液靜壓轉盤安全油路裝置。The invention relates to a processing machine, in particular to a hydrostatic rotary safety oil circuit device.
如圖1所示，現有一種液靜壓轉盤裝置，包含一液靜壓軸承1、一軸設在該液靜壓軸承1內部的驅動軸2、一油壓供應單元3及一制動單元4。該液靜壓軸承1內部設有多數油腔101，該驅動軸2具有一轉盤201及一制動盤202，該油壓供應單元3具有一馬達301、一受該馬達301驅動的泵浦302、一連接在該泵浦302與該等油腔101之間的油路303及一安裝在該油路303的蓄壓器304。該制動單元4具有一對分設在該制動盤202兩側的缸體401、一對可相對於該缸體401伸縮的制動件402及一對分別提供該等制動件402彈出彈力的彈簧403，該等缸體401與該油路303相接通。As shown in FIG. 1, a conventional hydrostatic rotary disk device includes a hydrostatic bearing 1, a drive shaft 2 disposed inside the hydrostatic bearing 1, an oil pressure supply unit 3, and a brake unit 4. The hydrostatic bearing 1 is provided with a plurality of oil chambers 101. The drive shaft 2 has a turntable 201 and a brake disc 202. The hydraulic supply unit 3 has a motor 301, a pump 302 driven by the motor 301, An oil passage 303 connected between the pump 302 and the oil chambers 101 and an accumulator 304 installed in the oil passage 303. The brake unit 4 has a pair of cylinders 401 disposed on two sides of the brake disc 202, a pair of brakes 402 that are retractable relative to the cylinder 401, and a pair of springs 403 that respectively provide the spring force of the brakes 402. The cylinders 401 are connected to the oil passage 303.
在正常狀態下，該馬達301驅動該泵浦302運轉，透過該油路303將液壓油導入該等油腔101中，使得該驅動軸2與該液靜壓軸承1之間形成有油膜，即可提供該驅動軸2順暢轉動。In a normal state, the motor 301 drives the pump 302 to operate, and the hydraulic oil is introduced into the oil chambers 101 through the oil passage 303, so that an oil film is formed between the drive shaft 2 and the hydrostatic bearing 1, that is, The drive shaft 2 can be smoothly rotated.
當發生停電或跳電的狀況時，該馬達301與該泵浦302因停電而停止運轉，此時，利用該蓄壓器304雖可使該等油腔101中的液壓維持一段時間，但該驅動軸2會因為慣性作用而保持在旋轉狀態。由於液靜壓軸承1大都應於大型轉盤201，該液靜壓軸承1幾乎無法消耗該驅動軸2的旋轉動能，若要藉由該蓄壓器304維持該等油腔101中液壓油之液壓至該驅動軸2停止，則需要極大的蓄壓器304或極多的蓄壓器304，大幅提高成本及空間配置的難度。另外，若要直接利用該制動單元4的該等制動件402箝制該制動盤202，且使該驅動軸2可在短時間內停止，則需要極大的制動力，一樣會大幅提高制動單元4的製造成本、維護成本、設計難度。When a power failure or a power failure occurs, the motor 301 and the pump 302 are stopped due to a power failure. At this time, the hydraulic pressure in the oil chambers 101 can be maintained for a period of time by the accumulator 304, but The drive shaft 2 is kept in a rotating state due to inertia. Since the hydrostatic bearing 1 is mostly applied to the large turntable 201, the hydrostatic bearing 1 can hardly consume the rotational kinetic energy of the drive shaft 2, and the hydraulic pressure of the hydraulic oil in the oil chamber 101 is maintained by the accumulator 304. When the drive shaft 2 is stopped, an extremely large accumulator 304 or a large number of accumulators 304 are required, which greatly increases the difficulty of cost and space arrangement. In addition, if the brake disc 202 is directly clamped by the brake members 402 of the brake unit 4, and the drive shaft 2 can be stopped in a short time, a great braking force is required, and the brake unit 4 is greatly improved. Manufacturing costs, maintenance costs, design difficulties.
因此，本發明之目的，即在提供一種在停電時利用轉動慣性可持續維持油路液壓且達到安全防護之液靜壓轉盤安全油路裝置。Accordingly, it is an object of the present invention to provide a hydrostatic turntable safety oil passage device that maintains oil passage hydraulic pressure and achieves safety protection by utilizing rotational inertia during a power outage.

When the electric power is stopped, the clutch 51 is engaged. The state is such that the power of the spindle unit 20 is coupled to the transmission member 52.
該制動單元60具有一對分設在該制動盤23兩側的制動器61及一設置在該第二油路45上且用以控制該等制動器61的控制器62，該等制動器61各具有一與該第二油路45導通的缸體611、一可相對於該缸體611伸縮的制動件612及一可提供該制動件612朝該制動盤23彈抵的彈性件613，本實施例的控制器62為液壓導引式四口二位閥，且具有一回復彈簧621，切換時可控制該第二油路45之液壓油引入該等缸體611，或自該等缸體611引出。The brake unit 60 has a pair of brakes 61 disposed on two sides of the brake disc 23 and a controller 62 disposed on the second oil passage 45 for controlling the brakes 61. Each of the brakes 61 has a brake unit 61. a cylinder block 611 that is electrically connected to the second oil passage 45, a brake member 612 that is expandable and contractible with respect to the cylinder block 611, and an elastic member 613 that can provide the brake member 612 to be biased toward the brake disc 23, which is the embodiment of the present invention. The controller 62 is a hydraulically guided four-port two-position valve and has a return spring 621. The hydraulic oil of the second oil passage 45 can be controlled to be introduced into or drawn from the cylinders 611 during switching.
再如圖2所示，在正常供電狀態下，該油壓供應單元40的馬達41驅動該泵浦42，且可使該第一油路43、該蓄壓器44與該第二油路45之液壓油都具有相當液壓。此時，該等油腔12中會導入液壓油，且使該轉軸單元20的軸桿段21與該液靜壓軸承10之間形成有油膜，即可提供該轉軸單元20順暢轉動。且該控制器62受該第二油路45之液壓導引可控制該等制動器61常保持在與該制動盤23分離的一鬆釋狀態，亦即，透過該第二油路45中的液壓油，可控制該控制器62切換該第二油路45之液壓油引入該等缸體611，且如圖2之實線所示，該等制動件612受液壓油之液壓作用可常保持在與該制動盤23分離的鬆釋狀態(此時該等彈性件613呈被壓縮狀態)。此時，該轉軸單元20受持續電力供給的正常運轉狀態下，該離合器51呈離的狀態，且使該轉軸單元20的動力與該傳動件52不連結。As shown in FIG. 2, in the normal power supply state, the motor 41 of the oil pressure supply unit 40 drives the pump 42 and the first oil passage 43, the accumulator 44 and the second oil passage 45 can be The hydraulic oils are quite hydraulic. At this time, hydraulic oil is introduced into the oil chambers 12, and an oil film is formed between the shaft section 21 of the shaft unit 20 and the hydrostatic bearing 10, so that the shaft unit 20 can be smoothly rotated. And the controller 62 is controlled by the hydraulic pressure of the second oil passage 45 to control the brakes 61 to be kept in a released state separated from the brake disc 23, that is, the hydraulic pressure in the second oil passage 45. Oil, the controller 62 can control the hydraulic oil of the second oil passage 45 to be introduced into the cylinders 611, and as shown by the solid line in FIG. 2, the brake members 612 can be constantly maintained by the hydraulic action of the hydraulic oil. A released state separated from the brake disc 23 (at this time, the elastic members 613 are in a compressed state). At this time, in the normal operation state in which the spindle unit 20 is continuously supplied with electric power, the clutch 51 is in a disengaged state, and the power of the spindle unit 20 is not coupled to the transmission member 52.
當加工機跳電、停電，且使該馬達41停止運轉時，該轉軸單元20仍會因慣性作用而繼續旋轉，此時，藉由該蓄壓器44可使該第一油路43、該等油腔12中的液壓油維持足夠的液壓，且使該等油腔12中的液壓油之液壓不會瞬間降壓，斷電的同時，該離合器51隨即轉換呈合的狀態，且使該轉軸單元20的動力透過該離合器51與該傳動件52產生連結，該轉軸單元20的轉動動能會經由該傳動單元50驅動該泵浦42繼續運轉，並使該轉軸單元20的轉動動能轉換成液壓能，即可取代該馬達41的動力而維持該等油腔12中液壓油之液壓一段時間。When the processing machine is powered off, power is off, and the motor 41 is stopped, the rotating shaft unit 20 continues to rotate due to the inertia. At this time, the first oil passage 43 can be made by the accumulator 44. The hydraulic oil in the oil chamber 12 maintains sufficient hydraulic pressure, and the hydraulic pressure of the hydraulic oil in the oil chambers 12 is not instantaneously depressurized. At the same time of power failure, the clutch 51 is then switched into a combined state, and the The power of the rotating shaft unit 20 is coupled to the transmission member 52 through the clutch 51. The rotational kinetic energy of the rotating shaft unit 20 drives the pump 42 to continue to operate via the transmission unit 50, and converts the rotational kinetic energy of the rotating shaft unit 20 into a hydraulic pressure. Alternatively, the power of the motor 41 can be replaced to maintain the hydraulic pressure of the hydraulic oil in the oil chambers for a period of time.
當該轉軸單元20的轉速低於該泵浦42工作的最低轉速且液壓供給消除時，該控制器62受到該回復彈簧621之彈力作用可控制該等制動器61由鬆釋狀態轉換成對該制動盤23產生制動的制動狀態，亦即，該第一油路43與該第二油路45中的液壓油之液壓已小於該回復彈簧621的彈力，即可切換該控、制器62並控制液壓油流向(圖未示)，該等缸體611中之液壓油洩壓，且該等制動件612受等該等彈性件613之彈力作用，可由鬆釋狀態轉換成一對該制動盤23產生制動的制動狀態(如圖2假想線所示)，該轉軸單元20隨即停止運轉，而不會受到轉動慣性作用而繼續轉動，且可避免該轉軸單元20與該液靜壓軸承10產生磨耗損壞。When the rotation speed of the rotation shaft unit 20 is lower than the minimum rotation speed of the operation of the pump 42 and the hydraulic supply is eliminated, the controller 62 is subjected to the elastic force of the return spring 621 to control the rotation of the brakes 61 from the released state to the brake. The disk 23 generates a braking state of the brake, that is, the hydraulic pressure of the hydraulic oil in the first oil passage 43 and the second oil passage 45 is smaller than the elastic force of the return spring 621, and the controller 62 can be switched and controlled. The hydraulic oil flows (not shown), the hydraulic oil in the cylinders 611 is depressurized, and the brake members 612 are subjected to the elastic force of the elastic members 613, and can be converted into a pair of the brake discs 23 by the released state. The braking state of the brake (as shown by the imaginary line in FIG. 2), the rotating shaft unit 20 then stops running without being rotated by the rotational inertia, and the wear of the rotating shaft unit 20 and the hydrostatic bearing 10 can be prevented from being damaged. .
因此，本發明之功效可歸納如下：Therefore, the effects of the present invention can be summarized as follows:
一、該傳動單元50在電力停止供給狀態下，該離合器51呈合的狀態，且使該轉軸單元20的慣性轉動動力與該傳動件52產生連結，可提供該泵浦42繼續運轉，所以利用小型的蓄壓器44即可維持該等油腔12中液壓油之液壓，可降低成本。1. The transmission unit 50 is in a state in which the power supply is stopped, and the clutch 51 is in a combined state, and the inertial rotational power of the rotary shaft unit 20 is coupled to the transmission member 52, so that the pump 42 can be continuously operated, so that the transmission unit 50 is used. The small accumulator 44 maintains the hydraulic pressure of the hydraulic oil in the oil chambers 12, thereby reducing costs.
二、利用該轉軸單元20之旋轉動能經由該傳動單元50傳回該泵浦42，能將旋轉動能轉化成液壓能，不但可取代該馬達41動力維持該等油腔12中液壓油之液壓一段時間，且旋轉動能轉化成液壓能的同時即可對該轉軸單元20產生制動作用。2. The rotary kinetic energy of the rotating shaft unit 20 is transmitted back to the pump 42 via the transmission unit 50, and the rotational kinetic energy can be converted into hydraulic energy, which can replace the power of the motor 41 to maintain the hydraulic pressure of the hydraulic oil in the oil chamber 12. Time, and the rotational kinetic energy is converted into hydraulic energy, and the rotating shaft unit 20 can be braked.
三、利用旋轉動能轉化成液壓能時的制動作用，可將該轉軸單元20的高轉速降至低轉速，所以利用小型之制動單元60即可達到制動效果，大幅降低該制動單元60的成本及該制動單元60的設計難度，維護成本也會大幅降低。3. The braking effect when the rotational kinetic energy is converted into hydraulic energy can reduce the high rotation speed of the rotating shaft unit 20 to a low rotating speed, so that the braking effect can be achieved by using the small braking unit 60, and the cost of the braking unit 60 is greatly reduced. The design difficulty and maintenance cost of the brake unit 60 are also greatly reduced.
