Description

Technical Field

[0001] The utility model belongs to the technical field of disc type hydraulic oil pumps, in particular to an energy-saving controllable disc type hydraulic oil pump. Background Art

[0002] A disc-type hydraulic oil pump generally refers to a swash plate-type hydraulic oil pump. A swash plate hydraulic oil pump mainly realizes the process of oil suction and discharge through the reciprocating motion of the plunger in the cylinder. The drive shaft drives the cylinder to rotate, and the plunger reciprocates in the cylinder hole. Due to the presence of the swash plate, when the cylinder rotates, the plunger rotates with the cylinder and also performs reciprocating axial motion in the cylinder hole under the action of the swash plate. When the plunger extends outward from the cylinder hole, the volume of the cylinder increases, forming a negative pressure, and the oil is sucked into the cylinder from the oil inlet. When the plunger retracts into the cylinder, the volume of the cylinder decreases, the oil is compressed, and discharged from the oil discharge port, thereby completing an oil suction and discharge process.

[0003] The hydraulic oil pump is usually connected to the engine's rotating shaft. When in use, the engine starts and the rotating shaft drives the oil pump to supply oil. However, when the engine is turned off, the engine does not stop immediately. At this time, the engine keeps driving the oil pump to supply oil, resulting in a waste of resources. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide an energy-saving controllable disc hydraulic oil pump.

[0005] To achieve the above-mentioned purpose, the utility model proposes an energy-saving controllable disc hydraulic oil pump, comprising an oil pump body, a rotating shaft being mounted on the oil pump body, a side of the oil pump body close to the rotating shaft being fixedly connected to a shell, a transmission shaft being provided on the shell, the rotating shaft being located inside the shell, an adjustable connecting assembly being provided inside the shell, and the adjustable connecting assembly being used to control the connection between the rotating shaft, the transmission shaft and the shell.

[0006] In one example, a special-shaped socket is provided on one side of the housing close to the transmission shaft, a special-shaped ring is fixedly connected to the outside of the transmission shaft, the special-shaped ring cooperates with the special-shaped socket, and the rotating shaft passes through the housing.

[0007] In one example, the adjustable connection assembly includes two vertical plates, which are fixedly connected to the shell, one side of the vertical plates is fixedly connected to a support plate, and the support plates are slidably connected to a sliding rod. The outer side of the rotating shaft is fixedly connected to a fixing ring, and an annular groove is provided on the fixing ring. A plurality of fixed blocks are fixedly connected in the annular groove, and a pushing member is provided on the support plate, and the pushing member is used to push the sliding rod.

[0008] In one example, one end of all the sliding rods is fixedly connected to a limit plate, a spring is fixedly connected between the limit plate and the supporting plate, and a curved surface is provided at the lower end of the sliding rod.

[0009] In one example, the pushing member includes two mounting seats, which are respectively fixedly connected to the supporting plate. The two mounting seats are rotatably connected to a rotating ring, and the outer side of the rotating ring is fixedly connected to two arc blocks.

[0010] In one example, the inner wall of the shell is fixedly connected to a support plate, one side of the support plate is fixedly connected to a servo motor, the main shaft of the servo motor is fixedly connected to a gear, and the outer side of the rotating ring is fixedly connected to multiple teeth, which are engaged with the gear.

[0011] The energy-saving controllable disc hydraulic oil pump proposed by the utility model can bring the following benefits:

[0012] Beneficial effects:

[0013] First, by providing an adjustable connecting assembly, the adjustable connecting assembly connects the rotating shaft to the housing. When the transmission shaft rotates, the transmission shaft can drive the housing to rotate and then drive the rotating shaft to rotate, thereby supplying oil. When oil supply is not needed, the adjustable connecting assembly disconnects the rotating shaft from the housing. At this time, the transmission shaft rotates and no oil is supplied, thereby avoiding waste and saving energy.

[0014] Secondly, by setting the arc block, the servo motor drives the gear to rotate, so that the two arc blocks on the rotating ring push up the limit plate, causing the sliding rod to slide, the lower end away from the fixed ring, and the spring to compress. When oil supply is needed, the servo motor reverses, the arc block disengages from the limit plate, and under the push of the spring, the lower end of the sliding rod is inserted into the fixed ring, and the rotating shaft is turned to rotate for oil supply. The structure is simple and easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0023] like Figures 1 to 4 As shown, the embodiment of the utility model proposes an energy-saving controllable disc hydraulic oil pump, which is characterized in that it includes an oil pump body 1, a rotating shaft 2 is installed on the oil pump body 1, the oil pump body 1 is fixedly connected to a shell 3 on one side close to the rotating shaft 2, a transmission shaft 4 is provided on the shell 3, the rotating shaft 2 is located in the shell 3, an adjustable connecting component 5 is provided in the shell 3, the adjustable connecting component 5 is used to control the connection between the rotating shaft 2, the transmission shaft 4 and the shell 3, a special-shaped socket is provided on the side of the shell 3 close to the transmission shaft 4, the outside of the transmission shaft 4 is fixedly connected to a special-shaped ring 6, the special-shaped ring 6 is matched with the special-shaped socket, the rotating shaft 2 passes through the shell 3, and the transmission shaft 4 is an external similar engine shaft, The transmission shaft 4 is mounted on the housing 3, and the special-shaped ring 6 is inserted into the special-shaped socket. The rotating shaft 2 of the oil pump body 1 is located in the housing 3. When the rotating shaft 2 needs to be rotated to make the oil pump body 1 supply oil, the adjustable connecting component 5 connects the rotating shaft 2 with the housing 3. When the transmission shaft 4 rotates, the transmission shaft 4 can drive the housing 3 to rotate and then drive the rotating shaft 2 to rotate to supply oil. When oil supply is not needed, the adjustable connecting component 5 disconnects the connection between the rotating shaft 2 and the housing 3. At this time, the transmission shaft 4 rotates and no oil is supplied, avoiding waste. Compared with most existing methods of directly connecting the transmission shaft 4 to the oil pump, this method saves energy.

[0024] like Figure 2As shown, the adjustable connection assembly 5 includes two vertical plates 51, the two vertical plates 51 are fixedly connected to the housing 3, one side of the vertical plates 51 is fixedly connected to the supporting plate 52, the supporting plate 52 is slidably connected to the sliding rod 53, the outer side of the rotating shaft 2 is fixedly connected to the fixing ring 54, the fixing ring 54 is provided with an annular groove, and a plurality of fixing blocks 55 are fixedly connected in the annular groove. A pushing member 7 is provided on the supporting plate 52, and the pushing member 7 is used to push the sliding rod 53. One end of all the sliding rods 53 is fixedly connected to the limiting plate 8, and a spring 9 is fixedly connected between the limiting plate 8 and the supporting plate 52. The lower end of 53 is provided with an arc surface. When continuous oil supply is required, the sliding rod 53 is inserted into the gap between the fixed blocks 55 on the fixed ring 54. By toggling the fixed blocks 55, the rotating shaft 2 is driven to rotate and oil is supplied. When oil supply is not required, the pushing member 7 pushes the sliding rod 53 to make the sliding rod 53 slide on the support plate 52, so that the sliding rod 53 leaves the fixed ring 54. At this time, the rotating shaft 2 loses connection with the housing 3 and the transmission shaft 4, which is convenient to use. At this time, if the transmission shaft 4 rotates by mistake or rotates ineffectively, the oil in the oil pump will not be wasted.

[0025] like Figure 3 and Figure 4 As shown, the pusher 7 includes two mounting seats 71, the two mounting seats 71 are fixedly connected to the support plate 52 respectively, the two mounting seats 71 are rotatably connected to the rotating ring 72, the outer side of the rotating ring 72 is fixedly connected to two arc blocks 73, the inner wall of the housing 3 is fixedly connected to the support plate 10, one side of the support plate 10 is fixedly connected to the servo motor 11, the main shaft of the servo motor 11 is fixedly connected to the gear 12, the outer side of the rotating ring 72 is fixedly connected to a plurality of teeth 13, the teeth 13 are meshed with the gear 12, and the pusher 7 pushes the sliding rod 53 At this time, the servo motor 11 is turned on, driving the gear 12 to rotate. At this time, the gear 12 drives the rotating ring 72 to rotate on the mounting seat 71, so that the two arc blocks 73 on the rotating ring 72 push the limit plate 8, causing the sliding rod 53 to slide, and the lower end is away from the fixed ring 54, and the spring 9 is compressed. When oil supply is needed, the servo motor 11 is reversed, and the arc block 73 is disengaged from the limit plate 8. Under the push of the spring 9, the lower end of the sliding rod 53 is inserted into the fixed ring 54, and the rotating shaft 2 is turned to rotate for oil supply. The structure is simple and easy to use.

[0026] Working principle: the transmission shaft 4 is installed on the housing 3, the special-shaped ring 6 is inserted into the special-shaped socket, and the rotating shaft 2 of the oil pump body 1 is located in the housing 3. When it is necessary to rotate the rotating shaft 2 to make the oil pump body 1 supply oil, the servo motor 11 reverses, and the arc block 73 disengages from the limit plate 8. Under the push of the spring 9, the lower end of the sliding rod 53 is inserted into the fixed ring 54. The transmission shaft 4 can drive the housing 3 to rotate and then drive the rotating shaft 2 to rotate to supply oil. When oil supply is not needed, the servo motor 11 is turned on and drives the gear 12 to rotate. At this time, the gear 12 drives the rotating ring 72 to rotate on the mounting seat 71, so that the two arc blocks 73 on the rotating ring 72 push up the limit plate 8, causing the sliding rod 53 to slide, and the lower end is away from the fixed ring 54. At this time, the transmission shaft 4 rotates and no oil is supplied.
