Description

Technical Field

[0001] The utility model relates to the technical field of lubrication of a middle carriage of a machine tool, in particular to a lubrication structure of a middle carriage of a machine tool. Background Art

[0002] The center carriage of a machine tool is an important part of the machine tool structure. It is usually used to support the workpiece and tool, as well as to transmit processing force and motion. When the machine tool is running, the center carriage needs to withstand the friction and processing force of the workpiece and tool, so the center carriage needs to be lubricated to reduce the wear of the center carriage.

[0003] The Chinese patent "A middle carriage lubrication structure for a machine tool" authorization announcement number "CN219465606U" filters the lubricating oil through an oil storage tank, an oil outlet pipe, a trough body and a filter screen to avoid blockage in the oil storage tank.

[0004] The above-mentioned oil storage tank and oil outlet pipe are provided on both sides of the pallet body, resulting in that when the lubricating oil is added, the oil outlet pipe starts to release oil for lubrication, causing some areas on the guide rail to be overlubricated and other areas to be less lubricated, thereby affecting the lubrication effect of the carriage in the machine tool.

[0005] Therefore, a middle carriage lubrication structure of a machine tool is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a lubricating structure for a middle carriage of a machine tool in order to solve the above-mentioned problem, thereby improving the problem that the lubrication effect of the middle carriage of the machine tool is not good.

The guide rod is used to limit the movable frame during movement, ensuring that the movable frame will not deviate during movement.

[0013] Preferably, the lower end of the oil inlet pipe surface forms an angle with the horizontal plane. The oil inlet pipe tilted downward ensures that the lubricating oil flows into the oil inlet pipe quickly.

[0014] Preferably, the oil inlet cover is in the shape of a truncated cone, and a rubber plug is clamped on the inner wall of the oil inlet cover. The rubber plug is used to seal the oil inlet cover and prevent impurities from entering the oil inlet pipe through the oil inlet cover.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-4As shown, a lubrication structure of a middle carriage of a machine tool comprises: a guide plate 1, a support plate 2 is slidably connected to the top of the guide plate 1, a screw rod 3 is rotatably connected to the inner wall of the guide plate 1, the inner wall of the support plate 2 is threadedly connected to the surface of the screw rod 3, and a lubrication mechanism 4 is arranged on the surface of the support plate 2; wherein the lubrication mechanism 4 comprises an oil injection pipe 41 fixedly connected to the inner wall of the support plate 2, the inner wall of the oil injection pipe 41 is connected to an oil inlet pipe 42, the other end of the oil inlet pipe 42 is connected to an oil inlet cover 46, and a movable frame 43 is arranged on the surface of the support plate 2, and the movable frame 43 A first smoothing block 44 is fixedly connected to the bottom, a fixed block 48 is fixedly connected to one side of the movable frame 43, and a plurality of second smoothing blocks 45 are slidably connected to the inner wall of the fixed block 48. A lubrication component 47 is provided on the surface of the support plate 2. The lower end of the surface of the oil inlet pipe 42 forms an angle with the horizontal plane. The shape of the oil inlet cover 46 is a truncated cone, and a rubber plug is clamped on the inner wall of the oil inlet cover 46. The first smoothing block 44 and the second smoothing block 45 are both made of polyurethane, so that the first smoothing block 44 and the second smoothing block 45 have high elasticity and wear resistance.

[0026] The front and rear ends of the inner side of the support plate 2 are not in contact with the front and rear ends of the guide plate 1. The bottom end of the oil injection pipe 41 is provided with a plurality of oil outlet holes, so that the oil injection pipe 41 sprays lubricating oil over a larger area.

[0027] When it is necessary to lubricate the carriage in the machine tool, the first smoothing block 44 abuts against the guide plate 1, the second smoothing block 45 abuts against the screw 3, the rubber plug on the oil inlet cover 46 is pulled to open the oil inlet cover 46, lubricating oil is poured into the oil inlet cover 46 and the screw 3 is rotated. The rotation of the screw 3 drives the support plate 2 to move on the guide plate 1, and the support plate 2 causes the oil spray pipe 41 to spray lubricating oil on the surface of the guide plate 1 and the screw 3 during the movement. The first smoothing block 44 moves to smooth the lubricating oil on the guide plate 1, and the second smoothing block 45 moves to smooth the lubricating oil on the screw 3.

[0028] like Figure 3-4 As shown, the lubrication assembly 47 includes a first spring 471 fixedly connected to the top of the second smoothing block 45, the top of the first spring 471 is fixedly connected to the inner top wall of the fixed block 48, the top of the movable frame 43 is fixedly connected to the second spring 472, the top of the second spring 472 is fixedly connected to the bottom of the support plate 2, the top of the movable frame 43 is fixedly connected to the guide rod 476, and the inner wall of the support plate 2 is slidably connected to the surface of the guide rod 476.

[0029] The elastic force of the second spring 472 pushes the movable frame 43 and the fixed block 48 downward, so that the first smoothing block 44 abuts against the guide plate 1 , and the elastic force of the first spring 471 pushes the second smoothing block 45 downward to abut against the screw rod 3 .

[0030] like Figure 3As shown, the front end of the support plate 2 is rotatably connected to a rotating wheel 473, the shape of the rotating wheel 473 is elliptical, the surface of the rotating wheel 473 is fixedly connected to a first magnetic block 474, and the front end of the support plate 2 is fixedly connected to two second magnetic blocks 475, and the first magnetic block 474 and the second magnetic block 475 attract each other with opposite poles.

[0031] The attraction between the first magnetic block 474 and the second magnetic block 475 is due to the interaction of the magnetic fields generated therebetween. The magnetic field generated by the first magnetic block 474 is in one direction, while the magnetic field generated by the second magnetic block 475 is in another direction. According to the law of magnetic field interaction, two objects with different magnetic field directions will attract each other.

[0032] When there is no need to smooth the lubricating oil on the guide plate 1 and the screw rod 3, rotate the rotating wheel 473, and the rotation of the rotating wheel 473 drives the first magnetic block 474 to move. The elliptical rotating wheel 473 pushes the movable frame 43 to move upward during the rotation, so that the first smoothing block 44 is away from the guide plate 1, and the second smoothing block 45 is away from the screw rod 3. The first magnetic block 474 is adsorbed on the corresponding second magnetic block 475 and stops rotating.

[0033] When the utility model is in use, the rotating wheel 473 is rotated to make the rotating wheel 473 move away from the movable frame 43. At this time, the elastic force of the second spring 472 pushes the movable frame 43 and the fixed block 48 to move downward, so that the first smoothing block 44 abuts against the guide plate 1. The elastic force of the first spring 471 pushes the second smoothing block 45 to move downward and abut against the screw rod 3, and the rubber plug on the oil inlet cover 46 is pulled to open the oil inlet cover 46. Lubricating oil is poured into the oil inlet cover 46 and the screw rod 3 is rotated. The rotation of the screw rod 3 drives the support plate 2 to move on the guide plate 1. During the movement of the support plate 2, the oil spray pipe 41 sprays lubricating oil on the surfaces of the guide plate 1 and the screw rod 3. The first smoothing block 44 moves to smooth the lubricating oil on the guide plate 1, and the second smoothing block 45 moves to smooth the lubricating oil on the screw rod 3.

[0034] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
