This automatic grease application is matched with the gap between the oiling plate and the screw rod, and the screw rod is convenient for oiling, which improves the production efficiency; an oil collecting tank is arranged to receive the lubricating oil dripping from the screw rod to prevent the grease from falling to the lower platform, which solves the problem of polluting the environment and causing harm to the operators walking through the lower layer, and at the same time facilitates the recovery of waste oil and improves the recovery rate of waste oil. The above patent provides a lubricating device that can receive the dripping lubricating oil when lubricating the screw rod.

[0004] In the prior art, the utility model patent with patent number CN202022234075.X discloses an automatic oiling fixture for a lead screw, including a base plate, a movable plate with intervals and parallels is provided on one side of the base plate, a cylinder is provided between the base plate and the movable plate, guide sleeves are provided at the four corners of the side opposite to the base plate and the movable plate, and a guide rod corresponding to the guide sleeve is provided on the side opposite to the base plate; an adjustment block that can move left and right is provided on the other side of the movable plate, and a rotating shaft is provided on the adjustment block, and a positioning sleeve is provided at the end of the rotating shaft facing the inside, and a cylindrical gear is provided at the other end of the rotating shaft, and the cylindrical gear is meshed with a driving gear, and the driving gear is fixed on the driving rotating shaft, and both ends of the driving rotating shaft are supported by side support plates, and the motor connection end at one end of the driving rotating shaft extends out of the side support plate.

[0030] The following is a further description in conjunction with the accompanying drawings and specific embodiments:

[0031] Embodiment 1

[0032] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, a lead screw lubrication tooling that can be remotely controlled includes an oil brushing seat 10, and also includes a connecting rod 6 and a tubing connection valve 15; the tubing connection valve 15 includes an oil inlet 1501, an oil outlet 1502, and a ball valve button 1503; the oil inlet 1501 is used to connect to an external oil supply device. A fixing seat 12 is arranged on the upper end surface of the oil brushing seat 10, and a working groove 1201 is arranged on the fixing seat 12; the working groove 1201 on the fixing seat 12 is an open cavity at the upper end and one side. The fixing seat 12 further includes a second mounting bolt 1202, the second mounting bolt 1202 is arranged at the bottom of the working groove 1201 of the fixing seat 12, a second bolt hole 1003 adapted to the second mounting bolt 1202 is arranged on the upper end surface of the oil brushing seat 10, and the second mounting bolt 1202 is installed in the second bolt hole 1003. The fixing seat 12 is fixedly installed on the upper end surface of the oil brushing seat 10 through the second mounting bolt 1202.

[0033] As Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, oil pipe connection valves 15 are symmetrically arranged on both sides of the fixed seat 12. A pair of ball valve buttons 1503 extend into the working groove 1201. Oil brush mounting seats 13 are connected to both of a pair of oil outlets 1502; through holes 1203 are symmetrically formed on the opposite side faces of the fixed seat 12. The oil pipe connection valves 15 are fixedly installed in the through holes 1203, and the ball valve buttons 1503 extend into the working groove 1201. The oil brush mounting seat 13 includes a connection hole 1301 and a third mounting bolt 1302; a connection hole 1301 that penetrates to the position of the bristles 14 is formed at the upper end of the oil brush mounting seat 13. The oil outlet 1502 of the oil pipe connection valve 15 is installed in the connection hole 1301; a third mounting bolt 1302 is arranged on one side of the oil brush mounting seat 13 close to the fixed seat 12. A third bolt hole 1204 is arranged at the corresponding position of the fixed seat 12 for the third mounting bolt 1302, and the third mounting bolt 1302 is installed in the third bolt hole 1204. The oil brush mounting seat 13 is connected to the oil outlet 1502, and oil can be supplied to the oil brush mounting seat 13 through the oil pipe connection valve 15 during the oiling process. The oil is transported to the oil brush through the connection hole 1301. Thus, the lubricating oil can be transported to the oil brush mounting seat 13 and applied through the bristles 14. At the same time, the oil brush mounting seat 13 is fixedly installed on both sides of the fixed seat 12 through the third mounting bolts 1302, which is convenient for disassembly and installation and has stable installation. The oil outlet 1502 and the connection hole 1301 at the upper end of the oil brush mounting seat 10 are connected by threads, and a sealing ring is arranged between the end face of the oil outlet 1502 and the bottom position of the connection hole 1301. The end face of the oil outlet 1502 is tightly abutted against the bottom of the connection hole 1301 through the sealing ring, and the thread is wound with raw tape, which can ensure its sealing performance and prevent the lubricating oil from leaking from the connection between the oil outlet 1502 and the connection hole 1301.

[0034] As Figure 1 , Figure 2 and Figure 5As shown, a brush hair 14 is provided at the lower end of the oil brush mounting base 13 through the oil brushing base 10; in addition, there is also an oil brushing curved surface 11. The lower end surface of the oil brushing base 10 is provided with an oil brushing curved surface 11 with a curved surface structure. The lower end of the oil brush mounting base 13 penetrates through the oil brushing base 10 and extends to the position of the oil brushing curved surface 11, where the brush hair 14 is provided. The oil brushing curved surface 11 is adapted to the bearing to be oiled. Thus, the oil brushing curved surface 11 can be abutted against the bearing to be oiled, facilitating the oiling work. At the same time, due to the radian of the oil brushing curved surface 11, it can be stably abutted against the bearing and will not fall off due to excessive force. The oil brushing base 10 further includes a mounting opening 1004. The oil brushing base 10 is provided with corresponding mounting openings 1004 at positions corresponding to the respective oil brush mounting bases 13. The oil brush mounting base 13 is inserted into the mounting opening 1004, and the lower end extends to the position of the oil brushing curved surface 11, where the brush hair 14 is provided. The lower end of the oil brushing base 10 extends to the position of the oil brushing curved surface 11 through the mounting opening 1004 and is provided with the brush hair 14. During the working process, the ball valve button 1503 is pushed by the pressing head 9 to open the oil pipe connection valve 15. The lubricating oil enters the connection hole 1301 through the oil pipe connection valve 15 and flows to the brush hair 14, and then the oiling work can be carried out. When the pressing head 9 does not press the ball valve button 1503 after the force is removed, the oil pipe connection valve 15 will close and stop delivering the lubricating oil. The lubricating oil remaining inside the connection hole 1301 will not flow out of the connection hole 1301 due to the viscosity and surface tension of the lubricating oil.

[0035] As Figure 1 , Figure 2 and Figure 3As shown, one end of the connecting rod 6 is elastically torsionally connected to the clamping shaft 1, and the other end is provided with a pressing head 9; in addition, it further includes a spherical joint bearing 3, and the connecting rod 6 and the clamping shaft 1 are movably connected through the spherical joint bearing 3; a first spring fixing plate 2 is arranged on the shaft body of the clamping shaft 1, and a second spring fixing plate 4 is arranged on the rod body of the connecting rod 6 close to the spherical joint bearing 3. A plurality of connecting springs 5 are sequentially connected between the first spring fixing plate 2 and the second spring fixing plate 4 along the circumferential direction thereof. The movable connection between the connecting rod 6 and the clamping shaft 1 through the spherical joint bearing 3 enables universal movement between the connecting rod 6 and the clamping shaft 1; at the same time, a plurality of connecting springs 5 are sequentially connected between the first spring fixing plate 2 and the second spring fixing plate 4 along the circumferential direction thereof, so that when the connecting rod and the clamping shaft 1 move in any direction, they will be subject to spring resistance, thereby enabling the connecting rod 6 and the clamping shaft 1 to automatically reset to the vertical position; at the same time, three groups of connecting springs 5 are arranged between the first spring fixing plate 2 and the second spring fixing plate 4, and a pair of connecting springs 5 are arranged in each group. A pair of connecting springs 5 are arranged in an eight-shaped opening. Through the uniform distribution of the three groups of connecting springs 5 along the circumferential direction, elastic resistance will be received in any direction between the connecting rod 6 and the clamping shaft 1; by setting this elastic movement structure, when the manipulator clamps the clamping shaft 1 and needs to deflect in a certain direction, a force can be applied in that direction to make the oiling seat 10 abut against the bearing to be oiled, and according to the direction of the force offset, elastic bending will occur between the connecting rod 6 and the clamping shaft 1, thereby enabling the change of the oiling direction.

[0036] As Figure 1 , Figure 3 one Figure 5 and Figure 8As shown in the figure, a mounting plate 7 is provided at the position of the rod body of the connecting rod 6 close to the pressing head 9, and the oil brushing seat 10 is elastically compressed and arranged on the mounting plate 7; in addition, it also includes a flange linear bearing 8, and flange linear bearings 8 are installed at the positions on both sides of the connecting rod 6 on the mounting plate 7; the flange linear bearing 8 includes a bearing body 801, and an installation seat 802 is arranged on the outer side of the lower end of the bearing body 801, and a plurality of first installation bolts 803 are arranged on the installation seat 802; installation holes 701 are arranged at the positions corresponding to the bearing body 801 on the mounting plate 7, and corresponding first bolt holes 702 are arranged at the positions corresponding to the first installation bolts 803 one by one.

Corresponding sliding rods 1001 are arranged on the upper end face of the oil brushing seat 10 at the positions corresponding to the flange linear bearings 8, and the sliding rods 1001 are slidably and spring-mounted on the flange linear bearings 8. The oil brushing seat 10 further includes a return spring 1002, the return spring 1002 is sleeved on the sliding rod 1001, and the sliding rod 1001 is elastically and slidably mounted on the flange linear bearing 8 through the return spring 1002. The pressing head 9 extends into the working groove 1201 and elastically abuts against the ball valve button 1503. When a force is applied to push the oil brushing seat 10, the oil brushing seat 10 will be elastically compressed on the mounting plate 7 through the sliding rod 1001 and the return spring 1002, so that the pressing head 9 on the connecting rod 6 extends into the working groove 1201 and pushes the ball valve button 1503 on the oil pipe connection valve 15, so that the oil pipe connection valve 15 is in a flowing state. When released, the oil pipe connection valve 15 will automatically close. Thus, the opening and closing control of the oil pipe connection valve 15 is realized.

[0039] As Figure 1 、 Figure 2 、 Figure 6 and Figure 7As shown, oil pipe connection valves 15 are symmetrically arranged on both sides of the fixed seat 12.

The oil brush mounting seats 13 are inserted into the mounting openings 1004, and the lower ends extend to the position of the oil brushing curved surface 11 and are provided with brush bristles 14. During the working process, by pushing the ball valve button 1503 with the pressing head 9, the oil pipe connection valve 15 is opened, the lubricating oil enters the connection hole 1301 through the oil pipe connection valve 15 and flows to the brush bristles 14, and then the oiling work can be carried out.

[0041] As Figure 1 , Figure 2 andFigure 3 As shown, one end of the connecting rod 6 is elastically and torsionally connected to a clamping shaft 1, and the other end is provided with a pressing head 9; in addition, a spherical joint bearing 3 is further included, and the connecting rod 6 and the clamping shaft 1 are movably connected through the spherical joint bearing 3; a first spring fixing plate 2 is arranged on the shaft body of the clamping shaft 1, and a second spring fixing plate 4 is arranged on the rod body of the connecting rod 6 close to the spherical joint bearing 3.

[0042] As Figure 1 、 Figure 3 shown Figure 5 in Figure 8 Figures 1 and 2, an installation plate 7 is arranged at the rod body position of the connecting rod 6 close to the pressing head 9; an oil brushing seat 10 is elastically compressed and arranged on the installation plate 7; in addition, a flange linear bearing 8 is further included, and flange linear bearings 8 are installed at positions on both sides of the connecting rod 6 on the installation plate 7; the flange linear bearing 8 includes a bearing body 801, an installation seat 802 is arranged on the outer side of the lower end of the bearing body 801, and a plurality of first installation bolts 803 are arranged on the installation seat 802; installation holes 701 are arranged at positions corresponding to the bearing body 801 on the installation plate 7, and first bolt holes 702 corresponding to the first installation bolts 803 are arranged at corresponding positions.

The pressing head 9 extends into the working groove 1201 and elastically abuts against the ball valve button 1503.

[0043] Working principle of the present invention: When using this device, the clamping shaft 1 is clamped by an external robotic arm, and then the clamping shaft 1 is controlled to apply force to push the oil-brushing seat 10 to abut against the bearing to be oiled. The oil-brushing seat 10 will be elastically compressed on the mounting plate 7 through the slide bar 1001 and the return spring 1002, so that the pressure head 9 on the connecting rod 6 extends into the working groove 1201 and pushes the ball valve button 1503 on the oil pipe connection valve 15, causing the oil pipe connection valve 15 to flow. When released, the oil pipe connection valve 15 will automatically close. Thus, controllable oiling can be achieved. The discharged oil can be evenly brushed by the bristles 14, and when brushing oil through the bristles 14, there is no need to continue pressing, so that lubricating oil will not be discharged again. When it is necessary to change the oiling direction, by applying force to push the clamping shaft 1 in the direction of deviation required, elastic activities of multiple groups of connecting springs 5 will occur between the connecting rod 6 and the clamping shaft 1, and the connecting rod 6 and the clamping shaft 1 will deviate in the direction of the applied force, causing elastic bending between the connecting rod 6 and the clamping shaft 1. Thus, the change of the oiling direction can be realized, and it can automatically return to the original state when the force is removed.

[0044] In summary, the present invention elastically sets the oil-brushing seat 10 on the mounting plate 7 provided on the connecting rod 6, and the oil discharge can be controlled by pressing the oil-brushing seat 10, so that the discharge of lubricating oil can be controlled according to the actual effect of oiling, ensuring that as much lubricating oil as needed is discharged, avoiding the dripping of lubricating oil, and the whole process can be operated by a robotic arm without manual contact with the device; by providing a spherical joint bearing 3 between the clamping shaft 1 and the connecting rod 6 and elastically constraining its periphery through the connecting spring 5, the oil-brushing seat 10 can be controlled to turn by applying an offset force, and it will automatically return after the force is removed, which is simple and practical with a simple structure.

[0045] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
