Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of screw rod and screw ring oiling, in particular to an oil-saving device for screw rod and screw ring oiling. Background Art
[0002] Lead screws are the most commonly used transmission components in tool machinery and precision machinery. Their main function is to convert rotational motion into linear motion, or torque into axial repetitive force. They also have the characteristics of high precision, reversibility and high efficiency. Due to their low friction resistance, lead screws are widely used in various industrial equipment and precision instruments.
[0003] The screw rod will wear out after being used for a long time, and the worn screw rod will affect the normal operation of the machine during use. Therefore, the screw rod needs to be lubricated after being used for a period of time. Usually, the lubrication is to manually apply lubricating oil to the surface of the screw rod or soak the screw rod in lubricating oil liquid and then take it out. This application method will increase the loss of lubricating oil and reduce the efficiency of lubrication. Therefore, we propose an oil-saving device for lubricating the screw rod. Utility Model Content
[0004] The object of the present invention is to provide an oil-saving device for lubricating a screw rod and a movable bell, by arranging a ball, so that the lubricating oil inside the oiling tank is applied to the surface of the screw rod through the oil inlet hole, and this method of directly inputting the lubricating oil into the gap between the movable bell and the screw rod can improve the lubrication efficiency. When the screw rod stops rotating, the movable bell stops sliding, thereby making the ball roller stationary, thereby reducing the lubrication of the screw rod by the lubricating oil, thereby saving lubricating oil, and solving the problem that the existing common lubrication method is to manually apply the lubricating oil to the surface of the screw rod or to immerse the screw rod as a whole in the lubricating oil liquid and then take it out, which will increase the loss of lubricating oil and reduce the working efficiency of the oiling.
[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
[0006] The utility model is an oil-saving device for lubricating a screw rod and a live bell, comprising a workbench, a first column fixedly connected to the top of the workbench, a second column fixedly connected to the top of the workbench, a motor fixedly connected to the right side of the first column, a connecting shaft fixedly connected to the output end of the motor, a screw rod plugged into the end of the connecting shaft away from the motor, a live bell threadedly connected to the outer surface of the screw rod, and the provision of the first column and the second column enables the screw rod to be fixed, making it convenient for workers to lubricate it;
[0007] An oil inlet hole is provided on the outer surface of the living bell, and an oil coating tank is provided on the outer surface of the living bell. An oil pipe is fixedly connected to the side of the oil coating tank away from the living bell, and the oil pipe passes through the inner wall of the oil coating tank and extends to the inside. The end of the oil coating tank close to the living bell is plugged into the inner wall of the oil inlet hole. A ball is provided at the bottom of the oil coating tank. The ball rotates, and the surface of the screw rod is uneven. The ball swings up and down while rotating, so that the lubricating oil inside the oil coating tank is coated on the surface of the screw rod through the oil inlet hole. This direct input of the lubricating oil into the gap between the living bell and the screw rod can improve the efficiency of lubrication.
[0008] Furthermore, a sliding rod is fixedly connected to the side where the second column and the first column are close to each other, and a fixing component is provided under the movable bell. The fixing component includes a sliding block slidably connected to the outer surface of the sliding rod. The shape of the sliding rod is square, and the sliding block can remain stable while sliding on the surface of the sliding rod and will not flip over.
[0009] Furthermore, a placement groove is opened inside the sliding block, and the inner wall of the placement groove is rotatably connected to two connecting rods. The ends of the two connecting rods away from the sliding block are rotatably connected to clamping blocks. The shape of the side of the clamping block close to the living bell fits the living bell, which can effectively clamp and fix the living bell.
[0010] Furthermore, an elliptical block is provided on the side where the two connecting rods are close to each other, and the elliptical block is rotatably connected to the inner wall of the placement groove through a circular shaft. The two ends of the circular shaft pass through the side walls of the sliding block and extend to the outside. The extended ends of the circular shaft are fixedly connected to pull rods. As the elliptical block rotates, the connecting rods on both sides are pushed to move, and as the bottoms of the connecting rods on both sides move away from each other, the tops of the two connecting rods are brought closer to each other.
[0011] Furthermore, the ends of the two pull rods away from the elliptical block are fixedly connected to the limiting rod, and the sides of the two connecting rods away from each other are fixedly connected to springs, and the ends of the two springs away from the elliptical block are fixedly connected to the inner wall of the placement groove, and the set springs can play a role in limiting the connecting rods.
[0012] Furthermore, a groove is provided on the front side of the sliding block, and the inner wall of the groove is slidably connected to a limit block. The limit block is fixedly connected to an end close to the groove with a spring block, and two arc-shaped spring plates are fixedly connected to the top of the second column. The inner walls of the two arc-shaped spring plates are rotatably connected to rollers. The elastic force generated by the spring block pushes the limit block away from the inside of the groove, so that the limit block limits the downward movement of the limit rod, thereby ensuring that the elliptical block clamp continuously clamps and fixes the living bell.
[0013] The utility model has the following beneficial effects:
[0014] 1. The utility model is provided with a ball bearing. Specifically, the staff connects the bottom of the oil coating tank with the oil inlet hole opened at the top of the movable bell. During the movement of the movable bell, the lubricating oil is injected into the interior of the oil coating tank through the oil pipe. The bottom of the oil coating tank is provided with a ball bearing. The ball bearing contacts the surface of the screw rod during the movement of the movable bell. During the contact process, the ball bearing rotates, and the surface of the screw rod is uneven. The ball bearing swings up and down while rotating, so that the lubricating oil inside the oil coating tank is applied to the surface of the screw rod through the oil inlet hole. This direct input of the lubricating oil into the gap between the movable bell and the screw rod can improve the lubrication efficiency. When the screw rod stops rotating, the movable bell stops sliding, so that the ball bearing is stationary, thereby reducing the lubrication of the screw rod by the lubricating oil, thereby saving lubricating oil.
[0015] 2. The utility model sets a fixing component. Specifically, when the sliding block moves to the bottom of the movable bell, the limit rod is pulled upward, and the limit rod drives the elliptical block to rotate through the pull rods on both sides. As the elliptical block rotates, the connecting rods on both sides are pushed to move. As the bottoms of the connecting rods on both sides move away from each other, the tops of the two connecting rods approach each other, thereby driving the two clamping blocks to approach the movable bell. When the clamping blocks on both sides contact the movable bell, they clamp it, thereby completing the fixation of the movable bell, so that the movable bell cannot rotate. Since the movable bell is fixed, the screw rod can maintain better stability during movement, thereby improving the axial stiffness of the entire transmission system.
[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0027] See also Figure 1-6 As shown, the utility model is an oil-saving device for lubricating a screw rod and a live bell, comprising a workbench 1, a first column 101 fixedly connected to the top of the workbench 1, a second column 102 fixedly connected to the top of the workbench 1, a motor 106 fixedly connected to the right side of the first column 101, a connecting shaft 107 fixedly connected to the output end of the motor 106, a screw rod 108 plugged into the end of the connecting shaft 107 away from the motor 106, and a live bell 109 threadedly connected to the outer surface of the screw rod 108;
[0028] An oil inlet hole 110 is provided on the outer surface of the living bell 109, and an oil tank 201 is provided on the outer surface of the living bell 109. An oil pipe 202 is fixedly connected to the side of the oil tank 201 away from the living bell 109. The oil pipe 202 passes through the inner wall of the oil tank 201 and extends to the inside. The end of the oil tank 201 close to the living bell 109 is plugged into the inner wall of the oil inlet hole 110, and a ball 203 is provided at the bottom of the oil tank 201. By providing the ball 203, the lubricating oil inside the oil tank 201 is applied to the surface of the screw rod 108 through the oil inlet hole 110. This direct input of the lubricating oil into the gap between the living bell 109 and the screw rod 108 can improve the efficiency of lubrication. When the screw rod 108 stops rotating, the living bell 109 stops sliding, so that the ball 203 is stationary, thereby reducing the lubrication of the screw rod 108 by the lubricating oil, thereby saving lubricating oil.
[0029] A sliding rod 105 is fixedly connected to the side where the second column 102 and the first column 101 are close to each other, and a fixing component 3 is provided below the movable bell 109. The fixing component 3 includes a sliding block 301 slidably connected to the outer surface of the sliding rod 105.
[0030] A placement slot 302 is defined inside the sliding block 301 . Two connecting rods 303 are rotatably connected to the inner wall of the placement slot 302 . One end of the two connecting rods 303 away from the sliding block 301 is rotatably connected to a clamping block 304 .
[0031] An elliptical block 305 is provided on one side of the two connecting rods 303 where the two connecting rods 303 are close to each other. The elliptical block 305 is rotatably connected to the inner wall of the placement groove 302 via a circular shaft.
[0032] The elliptical block 305 is rotatably connected to the inner wall of the placement groove 302 via a circular shaft. Both ends of the circular shaft pass through the side walls of the sliding block 301 and extend to the outside. The extended ends of the circular shaft are fixedly connected to the pull rod 306.
[0033] The ends of the two pull rods 306 away from the elliptical block 305 are fixedly connected to the limit rod 307, and the sides of the two connecting rods 303 away from each other are fixedly connected to the springs 308. The ends of the two springs 308 away from the elliptical block 305 are fixedly connected to the inner wall of the placement groove 302. By setting the fixing component 3, the fixation of the active bell 109 is completed, so that the active bell 109 cannot rotate. Since the active bell 109 is fixed, the screw rod 108 can maintain better stability during the movement, thereby improving the axial stiffness of the entire transmission system.
[0034] A groove is provided on the front of the sliding block 301, and the inner wall of the groove is slidably connected to a limit block 309. An elastic block 310 is fixedly connected to one end of the limit block 309 close to the groove. Two arc-shaped elastic plates 103 are fixedly connected to the top of the second column 102, and the inner walls of the two arc-shaped elastic plates 103 are rotatably connected to rollers 104.
[0035] A specific application of this embodiment is as follows: one end of the screw rod 108 is put in from the top of the column 2 102, the screw rod 108 squeezes the two roller arc spring plates 103 on the top of the column 2 102, and then the other end of the screw rod 108 is connected to the end of the connecting shaft 107. The staff moves the sliding block 301 to slide on the surface of the sliding rod 105. When the sliding block 301 moves to the bottom of the living bell 109, the limit rod 307 is pulled upward. The limit rod 307 drives the elliptical block 305 to rotate through the pull rods 306 on both sides. As the elliptical block The rotation of 305 pushes the connecting rods 303 on both sides to move. As the bottoms of the connecting rods 303 on both sides move away from each other, the tops of the two connecting rods 303 approach each other, thereby driving the two clamping blocks 304 to approach the live bell 109. When the clamping blocks 304 on both sides contact and clamp the live bell 109, the live bell 109 is fixed, so that the live bell 109 cannot rotate. Since the live bell 109 is fixed, the screw rod 108 can maintain better stability during the movement, thereby improving the axial stiffness of the entire transmission system.
[0036] When the clamping block 304 completes the fixation of the live bell 109, the limit rod 307 also moves to the top of the limit block 309. The limit rod 307 contacts the limit block 309 during the movement. As the limit rod 307 continues to move, the bottom inclined surface of the limit block 309 is squeezed by the limit rod 307 into the groove opened on the surface of the sliding block 301. The spring block 310 is squeezed to generate elastic force. When the limit rod 307 moves to the top of the limit block 309, the elastic force generated by the spring block 310 pushes the limit block 309 away from the inside of the groove, so that the limit block 309 limits the downward movement of the limit rod 307, thereby ensuring that the elliptical block clamp 304 continues to clamp and fix the live bell 109.
[0037] The starting motor 106 drives the screw rod 108 to rotate through the connecting shaft 107, and the live bell 109 slides on the surface of the screw rod 108 as the screw rod 108 rotates. Because the live bell 109 is fixed by the clamping blocks 304 on both sides, it drives the sliding block 301 to move synchronously on the surface of the slide rod 105. The staff connects the bottom of the oiling tank 201 with the oil inlet hole 110 opened on the top of the live bell 109. During the movement of the live bell 109, the lubricating oil is injected into the interior of the oiling tank 201 through the oil pipe 202. The bottom of the oiling tank 201 is provided with a A ball 203 is provided. When the movable bell 109 moves, the ball 203 comes into contact with the surface of the screw rod 108. During the contact process, the ball 203 rotates, and the surface of the screw rod 108 is uneven. The ball 203 swings up and down while rotating, so that the lubricating oil inside the oil tank 201 is applied to the surface of the screw rod 108 through the oil inlet hole 110. When the screw rod 108 stops rotating, the movable bell 109 stops sliding, so that the ball 203 is stationary, thereby reducing the lubrication of the screw rod 108 by the lubricating oil, thereby saving lubricating oil.
