Problems solved by technology

However, the current motorized grease filling equipment, such as ZL201420651309.2, basically only completes the function of actively opening and closing the oil injection port, which is difficult to apply to the grease filling of grease lubricated bearings, and manual hand-held grease guns are still required, especially for small diameter bearings. It is even more difficult, oiling around the circumference at a certain height above the ball, low production efficiency, workers' hands are sore and swollen, and the labor intensity is high

Embodiment 1

[0016] Embodiment 1: A kind of automatic bearing grease oiling machine, comprises oil drum, oil pump and the oil delivery pipe 1 that the electromagnetic valve controls, the reciprocating cylinder 7 that is positioned at the driving gear-rack mechanism motion on bed 11, wherein said electromagnetic valve controls The oil delivery pipe 1 is connected to the upper end of a hollow shaft 2, and the hollow shaft passes through a "7"-shaped support plate 3, and the gear 4 of the rack-and-pinion mechanism is arranged on the hollow shaft 2, and the hollow shaft The lower end of the oil filling and connecting oil box 5 and the oil filling nozzle 501 are connected, and the rack 6 of the gear-rack mechanism is connected with the piston head of the reciprocating cylinder 7; the upper cover of the oil filling and changing oil box 5 The left side of the plate 502 is threaded to the lower end of the hollow shaft 2 , and the right side of the lower cover plate 503 of the oil filling and switch...

Embodiment 2

[0018] Embodiment 2: An automatic bearing butter oiling machine, its working principle is the same as that of Embodiment 1, the difference is that the rack of the gear-rack mechanism is double-sided toothed, and the gears on both sides are driven to rotate at the same time, and the two sides can be operated at the same time. Fill the workpiece bearing with oil. The corresponding configuration is that the oil delivery pipe 1 is divided into two branches and connected to two parallel hollow shafts 2, and each hollow shaft is provided with a gear 4, and the lower end is respectively connected with an oil injection and replacement oil box 5 and an oil injection nozzle. 501. The equipment can complete the oil filling of 4 workpiece bearings in one working cycle.

Embodiment 3

[0019] Embodiment 3: An automatic bearing grease filling machine, its structure is the same as that of Embodiment 2, the difference is that the oil filling and changing oil box can be screwed and replaced to the end of the hollow shaft according to the change of the size of the workpiece bearing. Due to the different radii of the workpiece bearings, different oil filling cartridges can be applied to specific working conditions, including how much oil comes out of the oil filling port. The left side of the upper cover plate 502 of the oil filling and connecting oil box 5 is connected to the lower end of the hollow shaft 2 by threads, and the right side of the lower cover plate 503 of the oil filling and changing oil box 5 is connected to the oil nozzle 501 by threads, and the hollow shaft 2 The axial distance from the oil nozzle 501 changes with the workpiece bearing radius, and the opening of the oil nozzle 501 also changes accordingly.

[0020] In short, the structure of this...

Abstract

The invention relates to grease lubrication equipment, in particular to an automatic bearing grease injection machine. It specifically includes an oil barrel, an oil pump, an oil delivery pipe controlled by a solenoid valve, and a reciprocating cylinder that drives the gear-rack mechanism on the bed, wherein the oil delivery pipe controlled by the solenoid valve is connected to the upper end of a hollow shaft, and the hollow shaft passes through the Through the "7"-shaped support plate, the gear of the gear-rack mechanism is arranged on the hollow shaft. The rack is connected with the piston head of the reciprocating cylinder; the left side of the upper cover plate of the oil filling and changing oil box is connected to the lower end of the hollow shaft through threads, and the right side of the lower cover plate of the oil filling and changing oil box The side is threaded to the grease nipple. The invention solves the problem of even oiling of the small-diameter bearing butter in the whole circle, reduces operation errors, reduces labor intensity, improves production efficiency, and has low manufacturing cost for the whole set.

Description

Technical field [0001] The invention relates to grease lubrication equipment, in particular to an automatic bearing grease injection machine. Background technique [0002] Many moving parts of mechanical equipment need to be lubricated, and butter lubrication is one of the most common lubrication methods at present. At present, there are roughly two types of butter oiling equipment: manual butter oiling equipment and motorized butter oiling equipment. These two types of oiling equipment are used in different environments and characteristics. The motorized butter oiling machine has attracted more and more attention from the industry due to its large oil output, relatively long-lasting and efficient oil injection, simple operation and labor-saving, quantitative direction oil injection, and clean and environmentally friendly oil injection process. However, the current motorized grease filling equipment, such as ZL201420651309.2, basically only completes the function of activel...
