Description

Technical Field

[0001] The invention relates to the technical field of oil detection, and in particular to an oil detection device used in a tool grinding filter. Background Art

[0002] During the grinding process of the milling cutter, the grinding fluid is needed to lower the temperature of the grinding area, take away a large amount of grinding heat, and achieve lubrication and heat dissipation. After each use, the grinding oil will contain a large amount of processing impurities, resulting in larger oil residue impurity particles. Therefore, before using it again, the impurities in the grinding oil need to be precipitated, and then the next step of purification is carried out. At present, the industrial oil filter mainly consists of a dirty liquid tank, a clean liquid tank, a heater, a vacuum filter, a vacuum pump, an oil drain pump, a drainage pump and a cooling device.

[0003] The filter pump in the vacuum filter can filter different particle sizes and different quantities of metal debris in the oil at different operating frequencies, and the power consumption of the filter pump at different operating frequencies is also different. Therefore, the operating frequency of the filter pump can be changed by adjusting the frequency converter, so that it can accurately filter the metal debris in the oil at the lowest energy consumption, without causing unnecessary consumption of the frequency converter, thereby achieving the purpose of energy saving.

[0004] However, in order to accurately understand the filtering effect of the filter pump on the oil at different operating frequencies, it is necessary to test the oil transported to the clean oil tank after filtration again. This can accurately detect whether the filtering effect of the filter pump on metal particles of different particle sizes is excellent at different operating frequencies. In order to prevent uneven distribution of residual metal particles in the oil during the detection process, an oil detection device for a tool grinding filter is proposed. Summary of the invention

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Please refer to Figure 1-Figure 8 The present invention provides a technical solution: an oil detection device for a tool grinding filter, comprising an oil pipeline 1, a branch pipe 1 11 and a branch pipe 2 12 are arranged on the oil pipeline 1, a detection pipe 2 is arranged on the outer side of the oil pipeline 1, an oil inlet pipe 3 and an oil outlet pipe 4 are respectively arranged at the top and bottom ends of the detection pipe 2, the oil inlet pipe 3 is connected with the branch pipe 1 11, and the oil outlet pipe 4 is connected with the branch pipe 2 12, the oil pipeline 1 and the detection pipe 2 form a loop through the oil inlet pipe 3 and the oil outlet pipe 4, a stirring mechanism 5 and a filtering and intercepting mechanism 6 are arranged in the detection pipe 2, the stirring mechanism 5 and the filtering and intercepting mechanism 6 cooperate to filter and intercept metal particles in the oil flowing through the detection pipe 2 and make it evenly distributed in the detection pipe 2, a detection head 21 for detecting metal particles in the oil is through-set on the detection pipe 2, and the detection head 21 is located between the stirring mechanism 5 and the filtering and intercepting mechanism 6.

[0028] The oil pipeline 1 is provided with a valve three 7 and a flow meter 8. The valve three 7 is located between the branch pipe one 11 and the branch pipe two 12. The branch pipe one 11 is located between the valve three 7 and the flow meter 8. The oil inlet pipe 3 and the oil outlet pipe 4 are respectively provided with a valve one 31 and a valve two 41.

[0029] The stirring mechanism 5 includes a disc 51 rotatably mounted in the detection tube 2, and a plurality of one-way valves 52 are fixedly mounted through the disc 51. The filtering and intercepting mechanism 6 includes a hexagonal box 61 movably mounted in the detection tube 2, and a plurality of filter plates 62 distributed in a circular array are rotatably mounted on the outer side of the hexagonal box 61. A rotating shaft 1 56 and a rotating shaft 2 58 are fixedly mounted on the side where the disc 51 and the hexagonal box 61 are close to each other, and the ends where the rotating shaft 1 56 and the rotating shaft 2 58 are close to each other are connected to the same one-way bearing 59.

[0030] Furthermore, the arc-shaped side surface of the filter plate 62 abuts against the inner wall of the detection tube 2. When the filter plate 62 is horizontal, the entire arc-shaped side surface of the filter plate 62 contacts the inner wall of the detection tube 2. Since the contact area between the two is large, the filter plate 62 needs to overcome a large friction force to rotate with the second rotating shaft 58. At this time, when the rotating shaft 1 56 rotates forward, since the one-way bearing 59 can only transmit in one direction, the second rotating shaft 58 and the filter interception mechanism 6 will be in a stationary state.

[0031] When the filter plate 62 rotates with the circular shaft 63 as the center, the contact area between the arc-shaped side surface of the filter plate 62 and the inner wall of the detection tube 2 is small. At this time, when the rotating shaft 1 56 rotates in the opposite direction, the filter plate 62 only needs to overcome a small friction force to rotate with the rotating shaft 1 56.

[0032] A conical cylinder 53 and an end face gear ring 54 are fixedly installed on the top of the one-way valve 52. The conical cylinder 53 is rotatably connected to the inner wall of the detection tube 2. The end face gear ring 54 is fixedly sleeved on the outside of the conical cylinder 53. A driving gear 55 is meshed and connected to the end face gear ring 54. The stirring mechanism 5 also includes a motor 510 fixedly installed on the outside of the detection tube 2. The motor 510 rotates through the detection tube 2 and is fixedly connected to the driving gear 55. An impeller 57 is fixedly sleeved on the rotating shaft 56.

[0033] A circular shaft 63 is fixedly installed on one side where the multiple filter plates 62 are close to each other. The multiple circular shafts 63 all penetrate the hexagonal box 61 and are rotatably connected to the hexagonal box 61. A bevel gear 64 is fixedly installed on one end where the multiple filter plates 62 are close to each other. The same end face gear disc 65 is meshedly connected to the multiple bevel gears 64.

[0034] A cylinder 66 is rotatably installed on the hexagonal box 61, and the cylinder 66 penetrates the end toothed disc 65 and is fixedly connected to the end toothed disc 65. A round box 67 with an opening on the top is fixedly installed on the bottom of the hexagonal box 61. A spur gear 68 fixedly sleeved on the cylinder 66 is provided in the round box 67. Two racks 69 distributed in a circular array are meshed and connected to the spur gear 68. The two racks 69 both penetrate the round box 67 and are slidably connected to the round box 67.

[0035] A baffle 611 and a weight ball 610 are fixedly mounted on both ends of the rack 69 , and slopes 621 are provided on both sides of the filter plate 62 .

[0036] Furthermore, slopes 621 are provided on both sides of the filter plates 62 so that when each filter plate 62 rotates around the corresponding circular axis 63 , two adjacent filter plates 62 will not affect each other.

[0037] Two spring plates 613 are fixedly mounted on the inner wall of the round box 67 , and two levers 612 are fixedly mounted on the side of the cylinder 66 . The two levers 612 are in contact with the corresponding spring plates 613 , respectively.

[0038] Further, when the filtering interception mechanism 6 does not rotate, the state of the filtering interception mechanism 6 is as follows: Figure 3-Figure 5 As shown, when the filter interception mechanism 6 rotates at a high speed, the state of the filter interception mechanism 6 is as follows: Figure 7 As shown, in this state, when the filter interception mechanism 6 rotates clockwise, the metal particles originally falling on the top of the filter plate 62 will gradually fall down, and the cylinder 66 will deform the two spring plates 613 through the two levers 612 when rotating. When the filter interception mechanism 6 stops rotating, the two deformed spring plates 613 will reset and push the two levers 612 to rotate the cylinder 66 and restore it to its initial position.

[0039] In this embodiment: the oil pipeline 1 is used as the oil outlet pipeline of the clean oil tank, and the oil after filtration will flow out from the oil pipeline 1. When it is necessary to detect the residual metal particles in the oil flowing through the oil pipeline 1, first open the valve 1 31 and the valve 2 41 in the closed state, and close the valve 3 7 in the open state. At this time, the oil flowing through the oil pipeline 1 will flow from the oil inlet pipe 3 through the detection pipe 2, and then flow back into the oil pipeline 1 through the oil outlet pipe 4;

[0040] When the oil flows through the detection tube 2, the oil carries the residual metal particles through the multiple one-way valves 52, and after being filtered by the multiple filter plates 62, the oil will flow back into the oil delivery pipe 1 through the oil outlet pipe 4, and the residual metal particles in the oil will be filtered by the multiple filter plates 62 and accumulated between the disc 51 and the filter interception mechanism 6;

[0041] When it is necessary to calculate the content and size of residual metal particles in the oil, close valve one 31 and valve two 41 and open valve three 7. At this time, the oil will no longer flow through the detection tube 2. In the above process, the total amount of oil flowing through the detection tube 2 can be detected by the flow meter 8. Then the motor 510 is started to drive the driving gear 55 to rotate. The driving gear 55 rotates and then drives the end face gear ring 54 to rotate. The end face gear ring 54 then drives the rotating shaft one 56 to rotate through the disc 51. At this time, due to the one-way transmission of the one-way bearing 59, the rotating shaft two 58 will not rotate synchronously with the rotating shaft one 56. The rotating shaft one 56 rotates and stirs the oil remaining in the detection tube 2 through the impeller 57. As the oil is stirred, the residual metal particles between the disc 51 and the filtering and intercepting mechanism 6 will be evenly distributed in the stirred oil. At this time, the metal particle content and size in the oil can be more accurately detected by the particles through the detection head 21. Then, the metal particle content and size in the oil flowing through the detection tube 2 can be calculated.

[0042] When it is necessary to clear the intercepted metal particles in the detection tube 2 later, the motor 510 is controlled to reverse. At this time, the rotating shaft 1 56 will drive the rotating shaft 2 58 synchronously through the one-way bearing 59. The rotating shaft 2 58 rotates and then drives the entire filtering interception mechanism 6 to rotate. When the filtering interception mechanism 6 rotates at a high speed, the two weighted balls 610 will move away from the round box 67 under the action of centrifugal force. In this process, the two weighted balls 610 drive the spur gear 68 to rotate by pulling the corresponding rack 69. The spur gear 68 rotates and then drives the cylinder 66 to drive ... The movable end face toothed disc 65 rotates, and the end face toothed disc 65 drives the multiple bevel gears 64 to rotate synchronously. The multiple bevel gears 64 then drive the corresponding circular shafts 63 and filter plates 62 to rotate. As the filter plates 62 rotate with the circular shaft 63 as the center, the multiple filter plates 62 that were originally attached end to end will separate. At this time, the metal particles that fall on the top of the multiple filter plates 62 will fall and enter the oil outlet pipe 4. The metal particles that subsequently fall in the oil outlet pipe 4 will enter the oil pipeline 1 through the opened valve 2 41 during the next detection work.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
