Description

Technical Field

[0001] The utility model relates to an oiling mechanism and an automatic sheet material oiling machine comprising the oiling mechanism. Background Art

[0002] Existing oiling equipment, see Chinese utility model patent number: 2014205441576, name: automatic oiling device, authorization announcement date: January 28, 2015, which relates to an automatic oiling device that not only oils the workpiece quickly and evenly, but also saves oil and occupies less space. The upper end surface of the fixed base is horizontally provided with two mounting side plates and two rows of rubber rollers arranged up and down are installed between the two mounting side plates. A servo motor is installed on the outer mounting side plate and the servo motor drives the two rows of rubber rollers. The upper oil tank is installed between the two mounting side plates through two adjusting lifting plates and the upper oil tank is located directly above the upper row of rubber rollers. An oil storage tank and a funnel located above the oil storage tank are installed in the fixed base, and the upper port of the funnel is located directly below the lower row of rubber rollers, and the lower port is connected to the oil storage tank. The oil pump is installed on the oil storage tank, and the oil inlet of the oil pump is located in the oil storage tank, and the oil outlet is located in the upper oil tank. A sensor is provided between the fixed base and the automatic feeder.

[0003] However, the oiling mechanism of the above structure still has the following shortcomings: (1) The oil is pumped from the oil storage tank to the upper oil tank by an oil pump, and then falls onto the rubber roller and is adsorbed on the surface of the rubber roller. During continuous use, the amount of oil on different parts of the rubber roller surface is prone to be uneven, resulting in less oil or even no oil on some areas of the workpiece surface coated by the rubber roller, uneven oiling, and affected oiling effect; (2) The roller oiling module involves many parts, and the installation of the parts is complicated, that is, the overall structure of the roller oiling module is complex.

[0005] Another object of the utility model is to provide an automatic sheet material oiling machine including the above-mentioned oiling mechanism.

[0006] The purpose of the utility model is achieved in this way:

[0007] An oiling mechanism comprises an oiling box, an oiling cavity is formed on the oiling box, and an oil inlet connected to the oiling cavity is formed on the upper part of the side wall of the oiling box, wherein the upper oiling cavity is characterized in that a seating seat and an elastic member are arranged in the upper oiling cavity, the highest end of the seating seat is lower than the lowest end of the oil inlet, and the two ends of the elastic member are respectively abutted against the lower part of the seating seat and the inner bottom surface of the upper oiling cavity, so that the seating seat is elastically movable in the upper oiling cavity; in this oiling mechanism, a workpiece is placed on the seating seat, and the workpiece can be driven to move downward together with the seating seat by an external driving mechanism (such as a suction mechanism for sucking the workpiece), so that the workpiece is immersed in the oiling cavity, thereby ensuring that the workpiece is evenly and sufficiently oiled and the oiling effect is good.

In addition, the oiling mechanism involves fewer parts, the seating seat and the elastic member have simple structures, and the overall structure of the oiling mechanism is relatively simple.

[0015] Specifically, a second inner groove is provided on the upper surface of the seating seat located at the outer periphery of the seating groove, the second inner groove is connected with the seating groove, a plurality of second fixing holes are provided along the length extension direction of the second inner groove, an end of the second limiting member away from the seating groove is connected to one of the second fixing holes, and an arc limiting surface is provided at an end of the second limiting member close to the seating groove; the arc limiting surface is adapted to the outer surface of the workpiece to better limit the workpiece, and the second limiting member can be connected to different second fixing holes on the second inner groove to realize the change of the installation position on the second inner groove, thereby realizing the limitation of workpieces of different sizes and meeting the limitation requirements of workpieces of different sizes.

[0016] Specifically, a high-position oil drain port connected to the upper oil chamber is opened on the upper side wall of the upper oil tank, and the highest end of the high-position oil drain port is lower than the lowest end of the oil inlet; when the amount of oil in the upper oil chamber is excessive, it can be automatically discharged and recovered through the high-position oil drain port.

[0017] Another purpose of the utility model is achieved in this way:

[0018] An automatic sheet material oiling machine including the above-mentioned oiling mechanism also includes a frame and a second suction mechanism, the second suction mechanism is movably arranged on the frame, the second suction mechanism is located above the oiling mechanism and a retractable second suction arm is arranged on the second suction mechanism; in this automatic sheet material oiling machine, the second suction arm sucks the sheet workpiece and places it on a placement seat, and then the second suction arm drives the sheet workpiece to move downward together with the placement seat, so that the sheet workpiece is immersed in the oiling chamber, ensuring that the sheet workpiece is evenly and sufficiently oiled and the oiling effect is good. After the oiling is completed, the second suction arm moves upward, and the placement seat can move upward under the resetting action of the elastic member to complete the entire oiling process.

[0019] The beneficial effects of the utility model are as follows:

[0020] (1) In this oiling mechanism, the workpiece is placed on the seating seat, and can be driven by an external driving mechanism (such as a suction mechanism for sucking the workpiece) to move downward together with the seating seat, so that the workpiece is immersed in the oiling chamber, ensuring that the workpiece is evenly and sufficiently oiled and the oiling effect is good. After the oiling is completed, the driving force of the driving mechanism is withdrawn, and the seating seat can move upward under the resetting action of the elastic member. In addition, the oiling mechanism involves fewer parts, the structure of the seating seat and the elastic member is simple, and the overall structure of the oiling mechanism is relatively simple.

[0021] (2) The limit column has a good limiting effect on the downward movement depth of the placement seat, which can not only ensure that the workpiece can be immersed in the oiling chamber, but also prevent the placement seat from moving down too deep, thereby improving the overall oiling efficiency of the oiling mechanism.

[0022] (3) The mounting seat can be well restricted between the limit nut and the spring, ensuring the stable installation of the mounting seat on the upper oil chamber, while not affecting the elastic movement of the mounting seat itself. In addition, the connecting column provides an installation carrier for the spring so that the spring can stably drive the mounting seat to move. BRIEF DESCRIPTION OF THE DRAWINGS
