Description

Technical Field

[0001] The present application relates to the technical field of lubrication pumps, and in particular to an electromagnetic lubrication pump. Background Art

[0002] The electromagnetic lubrication pump is a fully automatic electric lubrication oil pump with low noise and high efficiency. It can achieve timed and quantitative oil supply without manual operation.

[0003] The current electromagnetic lubrication pump includes a pump body, which is provided with a suction cylinder. A piston rod is slidably installed in the suction cylinder. One end of the piston rod extends outside the suction cylinder. A spring is sleeved on one end of the piston rod. One end of the spring is fixedly connected to the mouth of the suction cylinder, and the other end of the spring is fixedly connected to the side wall of the piston rod. A solenoid valve is provided at one end of the pump body. The telescopic end of the solenoid valve extends into the pump body and is pressed against the piston rod. When the solenoid valve is activated, the telescopic end of the solenoid valve pushes the piston rod forward, and the piston rod squeezes the spring, which squeezes the grease out of the suction cylinder. When the telescopic end of the solenoid valve retracts, the spring releases its elastic force and drives the piston rod to press against the telescopic end of the solenoid valve. This process is repeated to pump the grease out of the pump body in a quantitative manner.

[0004] However, since the telescopic end of the solenoid valve and the moving stroke of the piston rod are fixed, it is ultimately impossible to adjust the oil output of the pump body according to actual needs, and the practicality of the electromagnetic lubrication pump is low. Utility Model Content

[0005] In order to facilitate the adjustment of the oil output of the electromagnetic lubrication pump and improve the practicality of the electromagnetic lubrication pump, the present application provides an electromagnetic lubrication pump.

[0006] This application provides an electromagnetic lubrication pump, which adopts the following technical solution:

[0008] By adopting the above technical solution, when the solenoid valve is started, the telescopic end of the solenoid valve drives the adjusting member forward, the adjusting member pushes the extruding member forward, and the extruding member squeezes the piston forward, thereby pumping oil; when it is necessary to adjust the oil output of the pump body, the adjusting member is driven to adjust and move in the extruding member, thereby extending or shortening the moving stroke of the extruding member, and when the moving stroke of the extruding member is extended, the oil output of the pump body increases, and conversely, the oil output of the pump body decreases, which is conducive to improving the convenience of adjusting the oil output of the electromagnetic lubrication pump.

[0009] Optionally, the adjusting member is a metering rod, an adjusting groove is provided at one end of the extrusion member facing the solenoid valve, the metering rod is slidably arranged in the adjusting groove, and the extrusion member is provided with a fixing component for fixing the metering rod.

[0011] Optionally, the metering rod is provided with various lengths.

[0012] By adopting the above technical solution, metering rods of different lengths are selected according to actual oil output requirements, which is conducive to improving the convenience of adjusting the oil output of the electromagnetic lubrication pump.

When it is necessary to adjust the position of the metering rod in the adjustment groove, the above steps are repeated and the insertion rod is inserted into another fixed groove, which is beneficial to improve the stability of the position adjustment and fixation of the metering rod in the extrusion member.

[0015] Optionally, the elastic member is a spring, which is arranged in the slide groove and sleeved on the insertion rod. One end of the spring is connected to the side wall of the insertion rod, and the other end of the spring is connected to the groove wall of the slide groove.

[0016] By adopting the above technical solution, when the insertion rod moves in the direction away from the metering rod, the insertion rod squeezes the spring and the insertion rod disengages from the fixed groove. When the insertion rod is released, the spring releases the elastic force and drives the insertion rod to move in the direction close to the metering rod. At this time, the insertion rod is inserted into one of the fixed grooves, which is beneficial to improve the stability of the position adjustment and fixation of the metering rod in the extrusion member.

[0017] Optionally, a wedge-shaped surface is provided at one end of the insertion rod.

When the piston resets, the piston resets and pushes the extrusion plate. Under the guidance of the cylinder, the extrusion plate abuts against one side of the cover seat, which is beneficial to improve the stability of the reciprocating movement of the piston.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] Example:

[0034] See also Figure 1 and Figure 2 , an electromagnetic lubrication pump, comprising a pump body 1. In this embodiment, the pump body 1 is an electromagnetic lubrication pump. A piston 2 is reciprocatingly slidably mounted in the pump body 1, and the number of pistons 2 is provided in two. A cover seat 3 is provided at one end cover of the pump body 1, and a solenoid valve 4 is fixedly mounted on the outside of the cover seat 3. The solenoid valve 4 includes a telescopic end, and the telescopic end of the solenoid valve 4 extends into the cover seat 3. An extrusion member 5 is slidably mounted on the inner side of the cover seat 3, and one end of the two pistons 2 is pressed against the extrusion member 5 together. An adjusting member is slidably mounted on the end of the extrusion member 5 away from the piston 2, and the adjusting member slides through the cover seat 3, and the telescopic end of the solenoid valve 4 is pressed against the adjusting member.

[0035] When the solenoid valve 4 is activated, the telescopic end of the solenoid valve 4 first moves forward, pushing the adjusting member forward, which in turn pushes the extruding member 5 forward, which in turn simultaneously moves the two pistons 2 forward. When the telescopic end of the solenoid valve 4 retracts, the two pistons 2 return to their original positions and push the extruding member 5 back, which in turn pushes the adjusting member back, keeping the adjusting member pressed against the telescopic end of the solenoid valve 4.

[0036] Because the telescopic end of the solenoid valve 4 has a constant travel distance, the travel distance of the extrusion member can be extended or shortened by sliding the adjustment member. When the extrusion member's travel distance is extended, the oil output of the pump body 1 increases. Conversely, when the extrusion member's travel distance is shortened, the oil output of the pump body 1 decreases.

[0037] For details, see Figure 3 The extrusion member 5 comprises an extrusion plate 6 and a cylinder 7. The extrusion plate 6 is a circular plate, and the cylinder 7 is coaxially fixed to one end of the extrusion plate 6. One end of each of the two pistons 2 simultaneously abuts against the end of the extrusion plate 6 facing away from the cylinder 7. The cylinder 7 slides through the cover 3, and the adjustment member is slidably mounted within the cylinder 7.

[0038] For details, see Figure 3 The adjusting member is a metering rod 8, which is cylindrical and available in various lengths. In this embodiment, the length of the metering rod 8 ranges from 18.4 mm to 19.2 mm. The length of the metering rod 8 is selected based on the actual required oil output. An adjusting slot 9 is defined at the end of the cylinder 7 facing the solenoid valve 4, and the metering rod 8 is slidably mounted within the adjusting slot 9.

[0039] See also Figure 3 To facilitate fine-tuning of the fixed position of metering rod 8 within adjustment slot 9, cylinder 7 is equipped with a fixing assembly comprising an insertion rod 10. A chute 11 is defined in the sidewall of cylinder 7, into which insertion rod 10 is slidably mounted. One end of insertion rod 10 passes through chute 11 and extends within cylinder 7. Metering rod 8 is also provided with a fixing slot 12 in its sidewall. There are at least two fixing slots 12, arranged in a linear array along the length of metering rod 8. One end of insertion rod 10 engages with each fixing slot 12.

[0040] See also Figure 3 In order to improve the stability of the insertion rod 10 when inserted into the fixed groove 12, the cylinder 7 is also equipped with an elastic member, which is a spring 13. The spring 13 is installed in the slide groove 11. The spring 13 is sleeved on the outer wall of the insertion rod 10, and one end of the spring 13 is fixedly connected to the outer wall of the insertion rod 10, and the other end of the spring 13 is fixedly connected to the groove wall of the slide groove 11.

[0041] When the rod 10 is pulled away from the metering rod 8, the rod 10 compresses the spring 13 and the rod 10 is released from the fixed slot 12. At this time, the metering rod 8 can be moved and adjusted in the adjustment slot 9. When the rod 10 is aligned with one of the fixed slots 12 and the rod 10 is released, the spring 13 releases its elastic force and drives the rod 10 to move toward the metering rod 8. At this time, the rod 10 is inserted into one of the fixed slots 12 and the metering rod 8 is fixed in the fixed cylinder.

[0042] It is worth noting that see Figure 3 One end of the insertion rod 10 is provided with a wedge-shaped surface 14. When the metering rod 8 is inserted into the cylinder 7, the metering rod 8 squeezes the insertion rod 10 through the wedge-shaped surface 14, thereby improving the sliding stability of the metering rod 8 in the cylinder 7.

[0043] It should be noted that, see Figure 2To facilitate the adjustment of the position of the metering rod 8 at any time, a screw seat 15 is fixedly installed in the pump body 1, and fixing bolts 16 are installed through the four end corners of the cover base 3. The number of screw seats 15 is the same as the number of fixing bolts 16, and the four fixing bolts 16 are threadedly connected to the four screw seats 15 respectively.

[0044] When the position of the metering rod 8 needs to be adjusted, the four fixing bolts 16 are unlocked, and the cover 3 is removed from the pump body 1, and the position of the metering rod 8 is adjusted. When the adjustment is completed, the cover 3 is closed first, and then the four fixing bolts 16 are tightened respectively. At this time, the cover 3 is fixed to the pump body 1.

[0045] Working principle of an electromagnetic lubrication pump:

[0046] Because the telescopic end of the solenoid valve 4 has a constant travel distance, the travel distance of the extrusion member can be extended or shortened by sliding the adjustment member. When the extrusion member's travel distance is extended, the oil output of the pump body 1 increases. Conversely, when the extrusion member's travel distance is shortened, the oil output of the pump body 1 decreases.

[0047] When it is necessary to fine-tune and fix the position of the metering rod 8, the insertion rod 10 is first pulled away from the metering rod 8. The insertion rod 10 compresses the spring 13 and the insertion rod 10 is disengaged from the fixing slot 12. At this time, the metering rod 8 can be moved and adjusted in the adjustment slot 9. When the insertion rod 10 is aligned with one of the fixing slots 12 and the insertion rod 10 is released, the spring 13 releases its elastic force and drives the insertion rod 10 to move toward the metering rod 8. At this time, the insertion rod 10 is inserted into one of the fixing slots 12, and the metering rod 8 is fixed in the fixing cylinder.

[0048] When the solenoid valve 4 is activated, the telescopic end of the solenoid valve 4 first moves forward, pushing the metering rod 8 forward, which in turn pushes the extrusion member 5 forward, which in turn simultaneously moves the two pistons 2 forward. When the telescopic end of the solenoid valve 4 retracts, the two pistons 2 return to their original position and push the extrusion member 5 back, which in turn pushes the metering rod 8 back, keeping the metering rod 8 pressed against the telescopic end of the solenoid valve 4.

[0049] Embodiment 2: The difference from Embodiment 1 is that the structure of the fixing component is different.

[0050] For details, see Figure 4The fixing assembly includes an adjusting bolt 17. The side wall of the cylinder 7 is provided with two through-holes 18, symmetrically arranged about the axis of the cylinder 7. The number of adjusting bolts 17 is the same as the number of through-holes 18, and the adjusting bolts 17 are plugged into the through-holes 18. The side wall of the metering rod 8 is provided with at least two sets of threaded grooves 19, spaced apart along the length of the metering rod 8. The adjusting bolts 17 are threadedly connected to the threaded grooves 19.

[0051] When it is necessary to fine-tune and fix the position of the metering rod 8 , first align the adjusting bolt 17 with one set of thread grooves 19 , and then tighten the adjusting bolt 17 . At this time, the metering rod 8 is fixed in the cylinder 7 .

[0052] In summary, since the telescopic end of the solenoid valve 4 has a constant travel distance, the travel distance of the extrusion member can be extended or shortened by sliding the adjustment member. When the extrusion member's travel distance is extended, the oil output of the pump body 1 increases. Conversely, when the extrusion member's travel distance is shortened, the oil output of the pump body 1 decreases, thereby facilitating the adjustment of the oil output of the electromagnetic lubrication pump.

[0053] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
