Description

Technical Field

[0001] This invention relates to the field of lubrication pumps, and more particularly to an electric multi-point lubrication pump. Background Technology

[0002] A lubrication pump is a lubrication device that supplies lubricant to lubrication points. Mechanical equipment requires regular lubrication. Previously, the main method of lubrication was manual lubrication based on the working condition of the equipment and after a certain maintenance cycle, such as the so-called grease application. Lubrication pumps make this maintenance work more convenient, and therefore are widely welcomed by the market.

[0003] To lubricate the guide rail slider module, a multi-point lubrication pump is currently used to connect the guide rail slider module. However, the existing multi-point lubrication pump is too large and lacks integration. Moreover, the reciprocating motion of the plunger will continuously generate friction with the push plate, leading to deformation and wear of the push plate. Summary of the Invention

[0004] The purpose of this invention is to provide an electric multi-point lubrication pump, which has the advantages of compact structure and is not prone to wear and deformation of the push plate.

[0005] To achieve the above objectives, the electric multi-point lubrication pump of the present invention includes an electric drive unit, a linear transmission module, a pump base, a push plate, an oil tank, and multiple oil-pumping plungers. The oil tank is installed on the pump base, and the multiple oil-pumping plungers are installed on the pump base. An oil inlet chamber is provided in the pump base, and the oil-pumping plungers pass through the oil inlet chamber, with the oil inlet of the oil-pumping plungers opening into the oil inlet chamber. The oil tank is connected to the oil inlet chamber. Each oil-pumping plunger includes a plunger rod. The linear transmission module is installed on the pump base, and the push plate is installed on the linear transmission module. The output end of the electric drive unit is connected to the linear transmission module. The electric drive unit drives the operation of the linear transmission module, which in turn drives the push plate to slide along the axial direction of the oil-pumping plunger. The end of the plunger rod is locked to the push plate by a retaining plate. The electric drive unit drives the operation of the linear transmission module, which in turn drives the push plate to slide back and forth along the axial direction of the oil-pumping plunger, thereby pulling out or pushing in the plunger rod, so that the oil-pumping plunger completes the oil suction and pumping actions.

[0006] Preferably, the plate has a mounting slot, and the end of the plunger rod is engaged in the mounting slot.

[0007] Preferably, the card plate is attached to one side of the push plate, and the card plate is locked to the push plate.

[0008] Preferably, the oil pump plunger also includes a plunger cylinder, which is mounted on the pump base. The plunger rod is axially slidably inserted into the plunger cylinder, and the oil inlet of the oil pump plunger is located on the side of the plunger cylinder.

[0009] Preferably, the oil outlet of the oil plunger is connected to an oil outlet connector, which is located on one side of the pump base.

[0010] Preferably, the bottom or side of the pump base is provided with a docking port, and the oil outlet of the oil pumping plunger is connected to the docking port.

[0011] Preferably, the electric multi-point lubrication pump of the present invention further includes a position sensor, which is disposed on one side of the push plate. The position sensor is used to sense the position of the push plate and to drive the electric drive device to move and stop the push plate. One side of the push plate is bent to form a detection part aligned with the position sensor. The detection part and the position sensor are arranged alternately.

[0012] Preferably, the electric multi-point lubrication pump of the present invention further includes a support base, the support base and the pump base are arranged alternately, the support base and the pump base are connected by a guide post, the linear transmission module is a lead screw and nut pair, the lead screw and nut pair are respectively installed on the support base and the pump base, the output end of the electric drive device is connected to the input end of the lead screw and nut pair, the push plate is installed on the output end of the lead screw and nut pair, and the push plate is also slidably installed on the guide post.

[0013] Preferably, the electric drive device includes a drive motor and a worm gear, the worm gear is mounted on a support base, the input end of the worm gear is connected to the output end of the drive motor, and the output end of the worm gear is connected to the output end of the lead screw nut.

[0014] Preferably, the push plate is a plate-shaped acetal steel structure, and the clamping plate is fixed to one side of the acetal steel structure with screws.

[0015] Compared with the prior art, the electric multi-point lubrication pump of the present invention includes multiple oiling plungers, and each oiling plunger includes a plunger rod. The end of the plunger rod is locked to the push plate by a retaining plate. The end of the plunger rod is not directly mounted on the push plate. The plunger rod directly contacts the retaining plate but not directly contacts the push plate, thus avoiding direct impact of the plunger rod on the push plate. The locking of the plunger rod by the retaining plate also improves the overall structural strength, effectively reducing the probability of wear and deformation of the push plate. Furthermore, the above arrangement also makes the overall structure compact. Attached Figure Description

[0025] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0026] The present invention provides an electric multi-point lubrication pump 100, which is used to provide lubricating oil to lubrication parts, moving parts, etc.

[0027] like Figures 1 to 7 As shown, the electric multi-point lubrication pump 100 of the present invention includes an electric drive unit 10, a linear transmission module 20, a pump base 30, a push plate 40, an oil tank 50, and multiple oiling plungers 60. The oil tank 50 is mounted on the pump base 30, and the multiple oiling plungers 60 are mounted on the pump base 30. An oil inlet chamber 31 is provided inside the pump base 30, and the oil tank 50 communicates with the oil inlet chamber 31. The oil inlet 61 of each oiling plunger 60 opens into the oil inlet chamber 31, and the oil tank 50 communicates with the oil inlet chamber 31. Each oiling plunger 60 includes a plunger rod 62. The linear transmission module 20 is mounted on the pump base 30, and the push plate 40 is driven and mounted on the linear transmission module 20. The output end of the electric drive unit 10 is connected to the linear transmission module 20, and the electric drive unit 10 drives the linear transmission module 20 to rotate, thereby causing the push plate 40 to slide along the axial direction of the oiling plunger 60. The end of the plunger rod 62 is locked to the push plate 40 by a retaining plate 70. The electric drive device 10 drives the linear transmission module 20 to move the push plate 40 back and forth along the axial direction of the oil pumping plunger 60, thereby pulling out or pushing in the plunger rod 62, so that the oil pumping plunger 60 can complete the oil suction and oil pumping action.

[0028] In the electric multi-point lubrication pump 100 of the present invention, a plurality of oiling plungers 60 are included, and each oiling plunger 60 includes a plunger rod 62. The end of the plunger rod 62 is locked to the push plate 40 by a retaining plate 70. The end of the plunger rod 62 is not directly mounted on the push plate 40. The plunger rod 62 directly contacts the retaining plate 70 but does not directly contact the push plate 40, thus avoiding direct impact of the plunger rod 62 on the push plate 40. The locking of the plunger rod 62 by the retaining plate 70 also improves the overall structural strength and effectively reduces the probability of wear and deformation of the push plate 40. Furthermore, the above arrangement also makes the overall structure compact.

[0029] Multiple oiling plungers 60 are mounted on the pump base 30, which helps to improve the integration of the equipment, making it more compact and reducing the size of the electric multi-point lubrication pump 100. The simultaneous operation of multiple oiling plungers 60 also enables simultaneous oiling at multiple points.

[0030] like Figures 1 to 7 As shown, in the embodiments provided by the present invention, the clamping plate 70 is generally a sheet or block structure. The clamping plate 70 has a mounting groove 71, and the end of the plunger rod 62 is inserted into the mounting groove 71. Preferably, the clamping plate 70 is attached to one side of the push plate 40, and the clamping plate 70 is locked to the push plate 40 to ensure stable installation of both and a compact structure.

[0031] like Figures 1 to 7 As shown, the oil pumping plunger 60 also includes a plunger cylinder 63, which is mounted on the pump base 30. The plunger rod 62 is axially slidably inserted into the plunger cylinder 63, and the oil inlet 61 of the oil pumping plunger 60 is opened on the side of the plunger cylinder 63.

[0032] This invention provides two methods for discharging lubricating oil. In the first embodiment, the oil outlet of the oil plunger 60 is connected to an oil outlet connector 64, which is located on one side of the pump base 30. This arrangement facilitates the discharging of lubricating oil. Please refer to the accompanying drawings for the first embodiment. Figure 1-7 In the first embodiment, the oil outlet connector 64 is designed to be easily connected to an oil pipe, thereby outputting lubricating oil.

[0033] In the second embodiment, a docking port 32 is provided on the bottom or side of the pump base 30, and the oil outlet of the oil pumping plunger 60 is connected to the docking port 32. Please refer to the attached drawings for the second embodiment. Figure 8 and Figure 9 The purpose of setting the docking port 32 is to facilitate docking with modules (such as guide rail slider modules).

[0034] like Figures 1 to 8As shown, the electric multi-point lubrication pump 100 of the present invention further includes a position sensor 80, which is disposed on one side of the push plate 40. The position sensor 80 is used to sense the position of the push plate 40 and to drive the electric drive device 10 to move and stop the push plate 40. One side of the push plate 40 is bent to form a detection part 41 aligned with the position sensor 80, and the detection part 41 and the position sensor 80 are arranged alternately.

[0035] like Figures 1 to 8 As shown, the electric multi-point lubrication pump 100 of the present invention also includes a support base 90. The support base 90 and the pump base 30 are arranged alternately and connected by a guide post 91. The linear transmission module 20 is a lead screw and nut pair, which is respectively mounted on the support base 90 and the pump base 30. The output end of the electric drive device 10 is connected to the input end of the lead screw and nut pair, and the push plate 40 is mounted on the output end of the lead screw and nut pair. The push plate 40 is also slidably mounted on the guide post 91. The support base 90 can enhance the support of the lead screw and nut pair and improve the stability of the overall structure. The guide post 91 connects the support base 90 and the pump base 30. The guiding property of the guide post 91 can ensure the smooth movement of the push plate 40 and make the overall structure of the equipment more compact.

[0036] like Figures 1 to 8 As shown, the electric drive device 10 includes a drive motor 11 and a worm gear 12. The worm gear 12 is mounted on a support base 90. The input end of the worm gear 12 is connected to the output end of the drive motor 11, and the output end of the worm gear 12 is connected to the output end of the lead screw nut. Preferably, in the embodiment provided by the present invention, the push plate 40 is a plate-shaped acetal structure, and the clamping plate 70 is fixed to one side of the acetal structure by screws.

[0037] The following is a brief description of the operation of the electric multi-point lubrication pump 100 of the present invention: The drive motor 11 drives the worm gear 12 to rotate, which in turn drives the lead screw and nut pair to rotate. This causes the push plate 40 to slide back and forth along the axial direction of the oil plunger 60, so that the plunger rod 62 extends and enters the plunger cylinder 63. The oil in the oil tank 50 flows into the oil inlet chamber 31. When the plunger rod 62 extends out of the plunger cylinder 63, the oil in the oil inlet chamber 31 flows into the plunger cylinder 63 through the oil inlet 61. When the plunger rod 62 enters the plunger cylinder 63, the plunger rod 62 pushes out the inflowing oil, which finally flows out from the oil outlet 64 or the connecting oil port 32. During this process, the position sensor 80 is used to sense the position of the push plate 40. When the push plate 40 is detected to have reached the designated position, the electric drive device 10 is stopped.

[0038] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
