[0001] The utility model relates to the technical field of flexible shaft processing, in particular to an oiling device which is convenient for fully oiling the flexible shaft. Background Art

[0002] In the field of automobiles or other mechanical equipment, flexible shafts are often used to connect two shafts with different axes and two shafts that are not in the same direction or have relative motion to transmit rotational motion and realize torque transmission. During the processing of flexible shafts, the flexible shafts need to be heat treated, and after heat treatment, it is usually necessary to use an oiling device to oil and maintain its surface.

[0003] For example, a Chinese patent document with announcement number CN219965370U discloses an oiling device for a flexible shaft after heat treatment, comprising a workbench, a collecting box fixedly connected to the bottom of the workbench, two groups of limiting blocks fixedly connected to the surface of the workbench, multiple groups of rotating rollers are rotatably connected to the surfaces of the two groups of limiting blocks, two groups of supporting frames fixedly connected to the top of the workbench, storage boxes fixedly connected to the tops of the two groups of supporting frames, a coating ring fixedly connected to the surface of the workbench, an oiling cavity is provided inside the coating ring, a coating groove is provided on the inner wall of the coating ring, an oiling pipe is fixedly connected to the bottom of the storage box, and two groups of reflux grooves are provided on the surface of the workbench.

[0004] In the above technical solution, the coating groove on the inner wall of the coating ring is provided so that the flexible shaft can be oiled on the surface of the flexible shaft when passing through the coating groove. However, the surface of the flexible shaft has a pitch, and the above oiling method mainly uses gravity to make the oil drip on the surface of the flexible shaft, which easily leads to insufficient oil coating in the groove between adjacent pitches. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an oiling device that is convenient for fully oiling the flexible shaft. When oiling the flexible shaft, a corresponding extrusion force can be applied to the flexible shaft so that the oil can be fully applied to each screw groove, so as to facilitate more sufficient oiling of the entire flexible shaft.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: an oiling device that is convenient for fully oiling a flexible shaft, comprises a frame, the frame is provided with a driving cylinder and a reset mechanism, the output end of the driving cylinder is provided with a mounting plate, pushing plates are provided at both sides of the mounting plate, and a connecting seat is symmetrically provided under the mounting plate, and the end of the connecting seat is rotatably connected to the oiling roller, and an oiling sponge is fixedly mounted on the surface of the oiling roller, and the pushing plate is located at one end facing the connecting seat and is provided with a pushing side wall whose height gradually decreases along the direction toward the connecting seat, and the connecting seat is located at one end facing the pushing plate and is provided with a coupling side wall adapted to the pushing side wall, the driving cylinder is used to push the connecting seats on both sides to move toward each other so that the oiling sponges on both sides are squeezed on the surface of the flexible shaft, and the reset mechanism is used to drive the connecting seats on both sides to move away from each other to realize the reset of the connecting seats on both sides, and a feeding roller and a winding roller are provided on both sides of the frame, and the winding roller is used to pull the flexible shaft on the feeding roller so that the flexible shaft passes through the oiling sponge.

[0007] The utility model is further configured as follows: the reset mechanism includes a moving rod, the frame is provided with a guide groove adapted to the moving rod, the moving rod passes through the guide groove, one end of the moving rod is fixed to a connecting seat, and the other end serves as a mounting end, a base is provided on the outside of the frame, a mounting flange is fixed on the outer periphery of the mounting end, a reset spring is provided between the mounting flange and the base, one end of the reset spring is fixed to the mounting flange and the other end is fixed to the base.

[0008] The utility model is further configured as follows: the push plate is provided with a clearance opening opposite to the moving rod, and the clearance opening is for the moving rod to pass through.

[0009] The utility model is further configured as follows: the frame is provided with support parts extending toward each other, the support parts are provided with penetrating guide holes, guide rods are provided on both sides of the connecting seat, the guide rods are adapted to the guide holes, the guide holes are for the guide rods to pass through, and can constitute a guiding fit between the two.

[0010] The utility model is further configured as follows: an oil collecting box is provided below the driving cylinder, and the oil collecting box is located between the oiling sponges on both sides.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the flexible shaft is oiled, the mounting plate is driven down by driving the cylinder so that the pushing side wall on the pushing plate gradually contacts the coupling side wall on the connecting seat. Since the pushing side wall decreases in height in the direction toward the connecting seat, the connecting seat can be pushed to move horizontally, so that the connecting seats on both sides can move toward each other. Therefore, the oiling sponge on the surface of the oiling roller connected to the connecting seat can squeeze the flexible shaft passing through the oiling sponge, so that the oil absorbed in the oiling sponge can be fully applied to the screw groove, and the oiling sponge can be deformed after being compressed, so that the oiling sponge can be fully fitted in the screw groove of the flexible shaft. As a result, after the winding roller drives the flexible shaft to move, the oil can be fully applied to each screw groove, so that the flexible shaft as a whole can be more fully oiled. Therefore, the technical problem of insufficient application of oil in the screw groove between adjacent screw pitches of the flexible shaft in the prior art is effectively solved.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0018] like Figures 1 to 3The utility model discloses an oiling device which is convenient for fully oiling the flexible shaft, comprising a frame 1, a driving cylinder 2 and a reset mechanism are arranged on the frame 1, a mounting plate 3 is arranged on the output end of the driving cylinder 2, a pushing plate 4 is arranged on both sides of the mounting plate 3, a connecting seat 5 is symmetrically arranged below the mounting plate 3, an end of the connecting seat 5 is rotatably connected with an oiling roller, an oiling sponge 6 is fixedly mounted on the surface of the oiling roller, a pushing side wall 41 which is located at one end facing the connecting seat 5 and is successively lowered in height along the direction facing the connecting seat 5, a coupling side wall 51 which is adapted to the pushing side wall 41 is arranged at one end facing the pushing plate 4, the driving cylinder 2 is used to push the connecting seats 5 on both sides to move toward each other so that the oiling sponges 6 on both sides are squeezed on the surface of the flexible shaft, the reset mechanism is used to drive the connecting seats 5 on both sides to move away from each other so as to realize the reset of the connecting seats 5 on both sides, a winding roller 7 and a winding roller 8 are arranged on both sides of the frame 1, and the winding roller 8 is used to pull the flexible shaft on the winding roller 7 so that the flexible shaft passes through the oiling sponge 6;

[0019] When the flexible shaft is oiled, the mounting plate 3 is driven down by driving the cylinder 2, so that the pushing side wall 41 on the pushing plate 4 gradually contacts with the coupling side wall 51 on the connecting seat 5. Since the pushing side wall 41 is lowered in height in the direction toward the connecting seat 5, the connecting seat 5 can be pushed to move horizontally, so that the connecting seats 5 on both sides can move toward each other. Therefore, the oiling sponge 6 on the surface of the oiling roller connected to the connecting seat 5 can squeeze the flexible shaft passing through the oiling sponge 6, so that the oil absorbed in the oiling sponge 6 can be fully applied to the screw groove, and the oiling sponge 6 can be deformed after being pressed, so that the oiling sponge 6 can be fully fitted to the screw groove. In the screw groove of the flexible shaft, as the winding roller 8 drives the flexible shaft to move, the oil can be fully applied to each screw groove, so that the flexible shaft as a whole can be more fully oiled, and through the setting of the oiling sponge 6, the adsorption amount of the oil on the oiling roller can be increased, thereby reducing the number of times the workers regularly oil the oiling roller, so as to reduce the labor intensity of the workers. The winding roller 8 and the feeding roller 7 are both conventional technologies, that is, after the flexible shaft reel is installed on the feeding roller 7, the flexible shaft on the flexible shaft reel is pulled toward the winding roller 8, and then the winding roller 8 is driven to rotate by the corresponding motor, so that the flexible shaft on the flexible shaft reel can be wound up, so that the flexible shaft passes through the oiling sponge 6.

[0020] In this embodiment, the specific structure of the reset mechanism includes a moving rod 91, and a guide groove adapted to the moving rod 91 is provided on the frame 1. The moving rod 91 passes through the guide groove. One end of the moving rod 91 is fixed to the connecting seat 5, and the other end serves as a mounting end. A base 92 is provided on the outer side of the frame 1, and a mounting flange 911 is fixed on the outer periphery of the mounting end. A reset spring 93 is provided between the mounting flange 911 and the base 92, and one end of the reset spring 93 is fixed to the mounting flange 911 and the other end is fixed to the base 92. Through the setting of the reset mechanism, after the pushing plate 4 pushes the connecting seat 5 to move, the mounting flange 911 can move toward the base 92 with the moving rod 91, so that the reset spring 93 can be squeezed. Therefore, after the driving cylinder 2 drives the pushing plate 4 to rise, the compressed reset spring 93 can drive the connecting seat 5 to reset so that it can be used again.

[0021] In this embodiment, a clearance opening 42 opposite to the moving rod 91 is provided on the pushing plate 4, and the clearance opening 42 is for the moving rod 91 to pass through. When the pushing plate 4 moves downward, the setting of the clearance opening 42 can prevent the moving rod 91 from interfering with the downward movement of the pushing plate 4, making the overall design more reasonable.

[0022] In this embodiment, the frame 1 is further provided with a support portion 10 extending toward each other, the support portion 10 is provided with a penetrating guide hole, and guide rods 11 are provided on both sides of the connecting seat 5. The guide rods 11 are adapted to the guide holes, and the guide holes are for the guide rods 11 to pass through, and can constitute a guiding fit between the two. By setting the support portion 10 and the guide rods 11, the connecting seat 5 can be supported to reduce the load on the moving rod 91, and as the connecting seat 5 moves, the guide rods 11 and the guide holes can be guided and matched to make the movement of the connecting seat 5 more stable.

[0023] In this embodiment, an oil collecting tank 12 is further provided below the driving cylinder 2. The oil collecting tank 12 is located between the oiling sponges 6 on both sides. Through the setting of the oil collecting tank 12, the oil dripping from the oiling sponge 6 and the flexible shaft after oiling can be recovered to a certain extent, so as to improve the utilization rate of the oil.
