Description
Technical Field
[0001] This utility model relates to the field of ball screw technology, specifically a fixing base for ball screws. Background Technology
[0002] A ball screw is a product that converts rotary motion into linear motion, or linear motion into rotary motion. It is widely used in machine tools, automation equipment, precision instruments and other fields. In practical applications, ball screws need to be installed on the equipment with a fixed base to ensure their stable operation.
[0003] The fixed base can support the screw body. When the screw body operates at high frequency for a long time, the contact parts between it and the inside of the fixed base will continuously bear friction and pressure. This continuous mechanical action will not only accelerate the wear of the surface material of the parts, causing problems such as increased surface roughness and decreased dimensional accuracy, but may also cause the mating clearance to gradually increase, which will lead to increased vibration, increased operating noise, and even reduced screw transmission accuracy, thus affecting the use by personnel in the later stage. Summary of the Invention
[0004] The purpose of this invention is to provide a fixing base for ball screws to solve the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a fixed base for a ball screw, comprising a base plate; an adjustment mechanism is installed on the top of the base plate, a lower clamping ring is installed on the top of the adjustment mechanism, an upper clamping ring is installed on the top of the lower clamping ring, fixing mechanisms are installed on both sides of the lower and upper clamping rings, a sponge layer is provided on the inner wall of the lower and upper clamping rings, a screw body is rotatably provided on the inner wall of the sponge layer, a top block is installed on the outer side of the screw body, a power mechanism is installed above the top block at the top of the upper clamping ring, a one-way valve is installed on the top and side of the power mechanism, and an oil storage tank is installed at one end of the one-way valve on the side.
[0006] Preferably, the adjustment mechanism includes a support disposed on the top of the base plate, a connecting rod being movably mounted through the interior of the support, and a lower clamping ring being connected to the top of the connecting rod.
[0007] Preferably, the fixing mechanism includes a fixing hole disposed inside the lower clamping ring, a fixing block is installed through the fixing hole at the bottom of the upper clamping ring, and spring blocks are installed on both sides of the fixing block near the bottom end of the lower clamping ring.
[0008] Preferably, the power mechanism includes a push rod disposed above the top block and located at the top of the upper clamping ring, a push plate being mounted on the top end of the push rod, and an outer frame being mounted on the outer side of the push plate.
[0009] Preferably, a spring is installed on the outer side of the push rod, one end of the spring is connected to the push plate, the other end of the spring is connected to the inner wall of the outer frame, and the side of the outer frame is connected to the oil storage tank through a one-way valve.
[0010] Preferably, a one-way valve is installed at the bottom of the oil storage tank.
[0011] Preferably, guide heads are provided on both sides of the bottom of the oil storage tank, and through holes are provided on the side of the guide heads.
[0012] Preferably, the top of the oil storage tank is provided with an oil injection hole, and a plug is installed inside the oil injection hole.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model utilizes a top block, a power mechanism, a one-way valve, an oil reservoir, and a sponge layer in conjunction. When the screw body rotates, it drives the outer top block to move, which in turn applies an upward thrust to the power mechanism. This causes the gas inside the power mechanism to enter the oil reservoir through the one-way valve on the side. When the gas pressure inside the oil reservoir increases, creating an environment higher than the external atmospheric pressure, the lubricating oil inside can be discharged to the sponge layer. When the screw body rotates, it comes into contact with the lubricated sponge layer, achieving the effect of lubricating the outside of the screw body. This reduces the friction generated when the screw body rotates. By intermittently supplying oil to the sponge layer, the waste and pollution caused by continuous oil supply when not in use can be avoided, thus preventing problems for personnel during later use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments;
[0022] Example:
[0023] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to the accompanying drawings. Figures 1 to 4 Please refer to the fixing base for ball screws provided in this application. Figure 1 , Figure 2 , Figure 3 and Figure 4 The system includes a base plate 1; an adjustment mechanism 2 is installed on the top of the base plate 1, a lower clamping ring 3 is installed on the top of the adjustment mechanism 2, an upper clamping ring 301 is installed on the top of the lower clamping ring 3, a fixing mechanism 4 is installed on both sides of the lower clamping ring 3 and the upper clamping ring 301, a sponge layer 7 is provided on the inner wall of the lower clamping ring 3 and the upper clamping ring 301, a screw body 5 is rotatably provided on the inner wall of the sponge layer 7, a top block 6 is installed on the outer side of the screw body 5, a power mechanism 601 is installed above the top block 6 on the top of the upper clamping ring 301, a one-way valve 602 is installed on the top and side of the power mechanism 601, and an oil storage tank 603 is installed at one end of the one-way valve 602 on the side.
[0024] Specifically, the base plate 1 provides a support platform for the installation of other components, ensuring the stability of the entire device. The adjustment mechanism 2 is used to adjust its operating height. The lower clamping ring 3 and the upper clamping ring 301 cooperate to form a structure for clamping the screw body 5. They fix the screw body 5 in the middle position, preventing the screw body 5 from shaking or shifting during operation, ensuring that the screw body 5 can rotate or move stably. The fixing mechanism 4 can firmly connect the lower clamping ring 3 and the upper clamping ring 301 together, enhancing the clamping force on the screw body 5 and further improving the reliability of the fixation. The sponge layer 7 is disposed on the inner wall of the lower clamping ring 3 and the upper clamping ring 301, and contacts the outer wall of the screw body 5. The sponge layer 7 has a certain elasticity and adsorption properties. On the one hand, it can play a buffering role, reducing the direct pressure of the clamping rings on the surface of the screw body 5 and preventing damage to the surface of the screw body 5. On the other hand, the sponge layer 7 can adsorb lubricating oil, providing continuous lubrication for the screw body 5, reducing the friction when the screw body 5 rotates, and extending its service life. The operation of the screw body 5 can convert rotary motion into linear motion. When the screw body 5 rotates, it will drive the outer top block 6 to move, and the top block 6 will exert pressure on the power mechanism 601. Applying an upward thrust causes the gas inside the power mechanism 601 to enter the oil reservoir 603 through the one-way valve 602 on the side. When the gas pressure inside the oil reservoir 603 increases, it creates an environment higher than the external atmospheric pressure, which allows the lubricating oil inside to be discharged to the sponge layer 7. When the screw body 5 rotates, it will come into contact with the sponge layer 7 containing lubricating oil, which can achieve the effect of lubricating the outside of the screw body 5, thereby reducing the friction generated when the screw body 5 rotates.
[0025] Please refer to this carefully. Figure 1 and Figure 2 The adjustment mechanism 2 includes a support 201 disposed on the top of the base plate 1, a connecting rod 202 being movably mounted through the inside of the support 201, and a lower clamping ring 3 being connected to the top of the connecting rod 202.
[0026] Specifically, in order to adjust the height of the fixed base, the operator moves the lower clamping ring 3, causing the connecting rod 202 at the bottom of the lower clamping ring 3 to move along the guide groove inside the support 201. Then, the position of the connecting rod 202 is fixed with a fixing nut, which allows the operator to easily adjust the height of the fixed base according to the actual usage.
[0027] Please refer to this carefully. Figure 1 and Figure 4 The fixing mechanism 4 includes a fixing hole 401 disposed inside the lower clamping ring 3. A fixing block 402 is installed inside the fixing hole 401 and located at the bottom of the upper clamping ring 301. Spring blocks 403 are installed on both sides of the fixing block 402 near the bottom end of the lower clamping ring 3.
[0028] Specifically, to facilitate the installation and disassembly of the screw body 5, the operator places the screw body 5 inside the lower clamping ring 3, then clamps the upper clamping ring 301 above the screw body 5, so that the fixing blocks 402 on both sides of the bottom of the upper clamping ring 301 pass through the fixing holes 401 inside the lower clamping ring 3. When the spring block 403 passes through the inside of the fixing hole 401 and is not squeezed by the inner wall of the fixing hole 401, the spring block 403 will move out under its own elastic force. When the spring block 403 is located on both sides of the bottom of the fixing hole 401, the upper clamping ring 301 can be fixedly installed above the lower clamping ring 3, and then the screw body 5 can be installed. Conversely, the screw body 5 can be quickly disassembled, thus facilitating the operator's operation.
[0029] Please refer to this carefully. Figure 2 , Figure 3 and Figure 4 The power mechanism 601 includes a push rod 6012 located above the top block 6 and at the top of the upper clamping ring 301. A push plate 6013 is installed at the top of the push rod 6012, and an outer frame 6011 is installed on the outer side of the push plate 6013.
[0030] Please refer to this carefully. Figure 4 A spring 8 is installed on the outside of the push rod 6012. One end of the spring 8 is connected to the push plate 6013, and the other end of the spring 8 is connected to the inner wall of the outer frame 6011. The side of the outer frame 6011 is connected to the oil reservoir 603 through a one-way valve 602.
[0031] Specifically, in order to supply air to the inside of the oil storage tank 603, when the top block 6 presses the push rod 6012, the push rod 6012 moves upward, the outer spring 8 deforms, and the push rod 6012 drives the push plate 6013 to move inside the outer frame 6011. This allows the gas inside the outer frame 6011 to supply air to the inside of the oil storage tank 603 through the one-way valve 602 on the side, so that the lubricating oil inside the oil storage tank 603 can be discharged. When the push rod 6012 is not pressed by the top block 6, the push rod 6012 and the push plate 6013 will reset under the action of the spring 8. At the same time, the external gas enters the inside of the outer frame 6011 through the one-way valve 602 at the top, preparing for the next air supply.
[0032] Please refer to this carefully. Figure 4 A one-way valve 6033 is installed at the bottom of the oil storage tank 603.
[0033] Please refer to this carefully. Figure 3 and Figure 4 The bottom of the oil storage tank 603 is provided with guide heads 6031 on both sides, and the side of the guide head 6031 is provided with through holes 6032.
[0034] Please refer to this carefully. Figure 2The top of the oil storage tank 603 is provided with an oil filling hole 6034, and a plug 6035 is installed inside the oil filling hole 6034.
[0035] Specifically, in order to deliver lubricating oil to the sponge layer 7 and lubricate the upper clamping ring 301, lower clamping ring 3, and screw body 5 to reduce friction between them, when gas is delivered to the inside of the oil storage tank 603, the lubricating oil inside the oil storage tank 603 will be delivered to the inside of the two sets of guide heads 6031 through the one-way valve 6033. Then, the lubricating oil is delivered to the sponge layer 7 through the through hole 6032 inside the guide head 6031. When the screw body 5 rotates, it will come into contact with the sponge layer 7 with lubricating oil, which can achieve the effect of lubricating the outside of the screw body 5, thereby reducing the friction generated when the screw body 5 rotates. Later, by removing the plug 6035 from the inside of the oil injection hole 6034, lubricating oil can be added to the inside of the oil storage tank 603 through the oil injection hole 6034.
[0036] Working principle: By placing the screw body 5 inside the lower clamping ring 3, and then clamping the upper clamping ring 301 above the screw body 5, the fixing blocks 402 on both sides of the bottom of the upper clamping ring 301 pass through the fixing holes 401 inside the lower clamping ring 3. When the spring block 403 passes through the inside of the fixing hole 401 and is not squeezed by the inner wall of the fixing hole 401, the spring block 403 will move out under its own elastic force. When the spring block 403 is located on both sides of the bottom of the fixing hole 401, the upper clamping ring 301 can be fixedly installed above the lower clamping ring 3, and then the screw body 5 can be installed. When the screw body 5 rotates, it will drive the outer top block 6 to move. When the top block 6 moves to the fixed position, the top block 6 will squeeze... Push rod 6012 moves upward, causing the outer spring 8 to deform. Push rod 6012 drives push plate 6013 to move inside outer frame 6011, allowing the gas inside outer frame 6011 to be supplied to oil reservoir 603 through one-way valve 602 on the side. When the gas pressure inside oil reservoir 603 increases, forming an environment higher than the external atmospheric pressure, the lubricating oil inside can be transported to the inside of the two sets of guide heads 6031 through one-way valve 6033. Then, the lubricating oil is transported to sponge layer 7 through through hole 6032 inside guide head 6031. When screw body 5 rotates, it will contact sponge layer 7 with lubricating oil, achieving the effect of lubricating the outside of screw body 5.
[0037] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications and equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
