Description

Technical Field

[0001] This utility model relates to the field of lubrication equipment, and more particularly to lubrication pumps. Background Technology

[0002] A lubrication pump, as a lubrication device, is used to inject lubricating oil into mechanical equipment for periodic lubrication, reducing frictional resistance of transmission pairs and slowing down wear. A lubrication pump generally includes an oil tank, pump base, pump body, and piping. The oil tank and pump body are respectively mounted on the pump base, which supports both. The pump base is generally made of cast metal (e.g., aluminum) and has internal flow channels for easy connection to the piping. The materials and manufacturing processes used for the pump base result in a relatively high cost, hindering cost reduction. Furthermore, some existing pump bases require painting, adding a painting process after casting the pump base, increasing processing complexity and costs.

[0003] Therefore, there is an urgent need for a lubrication pump that can reduce the cost of the pump base to overcome the above-mentioned defects. Utility Model Content

The first connector 50 is installed on the pump base 70, the first end of the connecting pipe 60 is connected to the pump oil flow channel, and the second end of the connecting pipe 60 is installed on and connected to the first connector 50.

[0025] During operation, the motor 10 drives the pump body 40 to operate, pumping the oil in the oil tank 20 to the pump oil channel. The oil in the pump oil channel flows through the connecting pipe 60 to the first connector 50. The oil flowing out from the first connector 50 is transmitted to the transmission pair to lubricate the transmission pair.

[0026] The lubrication pump 100 provided by this utility model includes a pump base 70, which is integrally injection molded, thus greatly reducing the cost of the pump base 70. Furthermore, the absence of flow channels within the pump base 70 also helps reduce mold costs and subsequent processing costs, thereby lowering the manufacturing cost of the pump base 70. The flow channels in existing designs are replaced by the first connector 50 of this utility model, ensuring smooth oil flow.

[0027] Preferably, the motor 10 is a stepper motor or a servo motor.

[0028] like Figures 1 to 6 As shown, the pump base 70 is arranged in a flat plate shape, and several mounting ears 71 are connected to the rear side of the pump base 70. The pump base 70 has mounting holes 72 that extend through in the vertical direction, and the first connector 50 passes through the mounting holes 72. The mounting holes 72 facilitate the installation of the first connector 50. The mounting ears 71 facilitate the fixing of the lubrication pump 100 to the equipment.

[0029] like Figures 1 to 6As shown, in order to facilitate the filling of oil into the oil tank 20, the pump base 70 is also provided with an oil filling port 73 that runs through the vertical direction. Oil is injected into the oil tank 20 through the oil filling port 73 to replenish the oil. An oil filling plug 74 is installed on the oil filling port 73.

Preferably, the depressurization valve 92 is located above the overflow valve 91, but it is not limited thereto.

[0032] like Figure 3 and Figure 4 As shown, the connecting seat 30 of this utility model is arranged in a columnar shape, and more specifically, the connecting seat 30 is generally cylindrical. Depending on actual needs, the connecting seat 30 can also be designed as a block shape. In the embodiment provided by this utility model, the pump body 40 is a gear pump structure, but it is not limited to this; the pump body 40 can also be applied to a plunger pump structure, etc.

[0033] like Figures 1 to 5 As shown, an oil pressure gauge 93 is installed on the first connector 50 to facilitate monitoring of the output oil pressure.

[0034] The pump base 70 of this utility model is integrally injection molded using a colored material. At this time, the pump base 70 is inherently colored, such as red, green, gray, etc., so there is no need to spray paint the pump base later.

[0035] like Figure 3 and Figure 4 As shown, a filter screen 41 is installed at the lower end of the pump body 40 to filter the oil in the oil tank 20 before pumping it out.

[0036] like Figure 5 and Figure 6As shown, the pump base 70 has a through-hole 75 extending vertically. The output shaft of the motor 10 passes through the through-hole 75. The top of the pump base 70 protrudes upward to form a frame-shaped mating boss 76. A protective shell 77 is also installed on the top of the pump base 70 to cover the motor. The protective shell 77 covers and is tightly fitted to the mating boss 76. The protective shell 77 protects the motor 10, while the mating boss 76 facilitates the positioning of the protective shell 77.
