Description

Technical Field

[0001] The utility model relates to the technical field of piston rod processing, in particular to an oil coating device for a main pump piston rod. Background Art

[0002] The main function of the pump is to transport liquid or pressurize the liquid. The main pump piston rod pulls the piston to move to achieve braking and other purposes. The piston rod is composed of a cylinder, a piston rod, a piston, and an end cover. During the production process of the piston rod, in order to prevent the piston rod from rusting, oiling the piston rod surface is called one of the essential processes for processing the piston rod.

[0003] For example, an oiling device for piston rod production with application number CN202121973318.X includes a box body, a first threaded rod is provided on one side of the inner wall of the box body, and a clamping structure is threadedly connected on the surface of the first threaded rod. The oiling device for piston rod production uses a third motor to drive the piston rod to rotate during the oiling process of the piston rod. On the one hand, it can make the piston rod fully contact with the oil, so that the oil is applied more evenly, solving the problem that the previous piston rod oiling device does not apply oil to the surface of the piston rod evenly. On the other hand, when the piston rod rotates, the excess oil on its surface can be thrown to the bottom to reduce waste. The excess oil can be filtered by a filter plate and reused, which is energy-saving and environmentally friendly, and ensures the quality of the oil. After the oiling is completed, the oil on the surface of the piston rod is dried in a drying box, replacing the previous natural air drying method, thereby saving piston rod production time and improving piston rod production efficiency.

[0004] The oiling device for piston rod production proposed in the above patent uses a clamping structure to clamp and fix the piston rod, and provides oil to the nozzle through an oil pump to spray oil on the surface of the piston rod. After the oil is sprayed, the first motor is used to drive the second threaded rod to rotate, thereby driving the clamping structure to enter the interior of the drying box. Before the piston rod after the oil is sprayed enters the drying box, the excess oil on the surface of the piston rod will be scraped off by a brush to make the oil on the surface of the piston rod more evenly distributed. Since the brush is fixedly installed on one side of the outer wall of the drying box, the brush is prone to oil stains or knots after long-term use, which causes the piston rod to pass through the dirty brush, affecting the effect of oiling the surface of the piston rod.

[0005] Therefore, we propose an oiling device for the piston rod of the main pump to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide an oiling device for the piston rod of a main pump, so as to solve the problem proposed in the above background technology that since the brush is fixedly installed on one side of the outer wall of the drying box, the brush is prone to produce oil stains or knots after long-term use, resulting in the piston rod passing through the dirty brush, which affects the effect of oiling the piston rod surface.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an oiling device for a piston rod of a main pump, comprising a box body and a driving and clamping assembly arranged on one side of the inner wall of the box body, an oil spraying assembly is fixedly installed at one end of the box body, a filtering assembly is arranged in the inner cavity of the box body, a drying assembly is arranged in the inner cavity of the other end of the box body, a sweeping brush assembly is fixedly installed on the inner wall of the other end of the box body, and the sweeping brush assembly is arranged to remove excess oil on the surface of the piston rod before the driving and clamping assembly moves the piston rod to the drying assembly;

[0008] The sweeping brush assembly comprises a mounting mechanism and a shielding mechanism fixedly mounted on one side of the upper end of the mounting mechanism. The shielding mechanism is arranged to shield the oil stains ejected when the mounting mechanism sweeps the piston rod.

[0009] Preferably, the box body comprises a semi-open frame and an insertion slot provided in the middle of one side of the upper end of the semi-open frame.

[0010] Preferably, a plurality of circular grooves are linearly and evenly spaced on both sides of the inner wall of the insertion groove, and an embedding groove is formed in the middle of both sides of the upper end of the semi-open frame.

[0011] Preferably, the mounting mechanism comprises a pressing plate and pulling rods fixedly mounted on both ends of one side of the top surface of the pressing plate, and an embedding block is fixedly mounted on the lower end of the pressing plate.

[0012] Preferably, a plurality of elastic elements are linearly and evenly spaced on both sides of the outer wall of the embedded block, a semicircular clamping ball is fixedly mounted on one end of the elastic element, and a brush is planted on the lower end of the embedded block.

[0013] Preferably, the shielding mechanism includes an open baffle and insertion rods fixedly mounted on both sides of the lower end of the open baffle.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. When the brush needs to be cleaned, pull the pull rod to drive the embedded block to be pulled out from the inner cavity of the insertion groove, so that the semicircular card ball automatically pops out from the inner cavity of the circular groove under the elastic force of the elastic element. When the brush is taken out from the inner cavity of the insertion groove for cleaning, the open baffle fixed at one end of the upper end of the pressing plate will be taken out together when the pressing plate is taken out. The operator can clean the oil stains bursting out from the inner wall of the open baffle at the same time.

[0016] 2. After the movable shaft is sprayed with oil by the oil spraying assembly, the movable shaft is driven by the driving clamping assembly to pass through the brush, and the brush removes excess oil on the surface of the movable shaft. When the brush is brushing, it will cause the oil to splash, and open baffles are arranged around the upper end of the brush to improve the cleanliness of the brush during operation.
