Description

Technical Field

[0001] The invention relates to the technical field of reducing machine base fixing, and more specifically to a reducing machine position limiting fixing mechanism. Background Art

[0002] The fixing mechanism of the reducer usually refers to the bracket, base or mounting structure used to install and fix the reducer itself. The design and selection of these fixing mechanisms are crucial to the stability, safety and performance of the reducer. The following are several common fixing mechanisms for reducers.

[0003] The existing fixing mechanism fixes the reducer on the fixing bracket by using bolts. Since the bottom ends of the bolts are generally welded to the fixing bracket, the fixing bolts may become loose due to vibration after being fixed. At the same time, when the bolts are in use, friction is generated under vibration due to long-term use of the bolts, which causes the bolts to rust faster, making it difficult to disassemble the bolts due to rust in the later stage. Therefore, the present invention provides a fixing mechanism for limiting the reducer. Summary of the invention

The liquid leakage bead can move in the liquid leakage groove and the liquid leakage pipe. A drip port is provided at the bottom end of the drip pipe. The drip port of the drip pipe is directly opposite to the middle of the top end of the fixing bracket screw.

[0009] Further, a ball valve pipe is provided at the top end of the debris collection pipe. A collection ball valve is installed in the ball valve pipe. The top end of the debris collection pipe is fixedly connected to the bottom end of the oil injection device. The top end of the debris collection pipe communicates with the bottom end of the lowest part of the inclined end of the oil injection device. The bottom end of the debris collection pipe is connected with a sealing block through a hinge.

[0011] Technical effects and advantages of the present invention: 1. The present invention is provided with a clamping block, which is conducive to limiting the position of the fixing nut by the parallel clamping slot and the diagonal clamping slot, so that the fixing nut will not rotate under vibration, causing the connection with the fixing bracket screw to become loose and affect the fixing effect. Therefore, by limiting the problem of vibration of the fixing nut under vibration, the limiting fixing effect is greatly improved.

[0012] 2. The present invention is provided with a leakage pipe, which is conducive to the vibration of the reducer causing the leakage spring to expand and contract. When expanding and contracting, the waste oil in the oil injection device will flow into the dripping pipe from the gap between the leakage bead and the leakage pipe, and then drip on the top of the fixed bracket screw through the dripping port of the dripping pipe, thereby dripping on the fixed bracket screw. The oil droplets dripping on the fixed bracket screw will slowly accumulate on the fixed bracket screw and the fixed nut, and then slowly penetrate into the entire fixed bracket screw from the fixed nut, thereby reducing the friction of the fixed bracket bolt and the fixed bracket screw during vibration when the reducer is running, and preventing the subsequent surface threads of the fixed bracket screw and the inner threads of the fixed nut from rusting, thereby ensuring the service life of the fixed bracket screw and ensuring the later disassembly and installation.

[0013] 3. The present invention is provided with a debris collection pipe. The oil injection device moves the debris in the waste oil toward the lower end debris collection pipe during vibration, so that the debris falls into the debris collection pipe and first enters between the collection ball valve and the blocking block of the debris collection pipe through the collection ball valve. As the debris accumulates, it is observed through the collection observation window that the debris reaches a certain thickness. At this time, the buckle is opened to collect the debris gathered in the debris collection pipe, so that the metal in the debris can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of the respective structures described in the following embodiments are merely examples, and the fixed mechanism for limiting the reducer related to the present invention is not limited to the respective structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0026] Refer to Figure 1-10The present invention provides a fixing mechanism for limiting a reducer, comprising a reducer base 1, wherein fixing side plates 101 are provided at the bottom ends of both sides of the reducer base 1, and fixing grooves 102 are provided at one end of the reducer base 1 located at the fixing side plates 101, and a support frame is installed at the bottom end of the fixing groove 102, and a fixing bracket bolt 1011 is installed at the support frame at the bottom end of the fixing groove 102, and a fixing bracket screw rod 1012 is fixedly connected to the top end of the fixing bracket screw rod 1011, and a fixing nut 1013 is threadedly connected to the top end of the fixing bracket screw rod 1012, and the fixing bracket bolt 1011 passes through the fixing groove 102 through the fixing bracket screw rod 1012 and is fixedly connected to the support frame using the fixing nut 1013, and the fixing side plate 101 is provided at one side of the fixing groove 102 There is a clamping groove 103, and a clamping device 2 is installed at the clamping groove 103. The clamping device 2 includes a support rod 201, and a clamping block 202 is movably sleeved on the outer wall of the bottom end of the support rod 201. The clamping block 202 is located at the support rod 201 and is provided with a rotating groove 2021. The clamping block 202 rotates on the support rod 201 through the rotating groove 2021. A torsion spring accommodating groove 20211 is provided at the bottom end of the rotating groove 2021 of the clamping block 202. A telescopic torsion spring 203 is installed at the bottom end of the torsion spring accommodating groove 20211. The outer wall of the bottom end of the support rod 201 located at the torsion spring accommodating groove 20211 is movably sleeved with the telescopic torsion spring 203. The bottom end of the telescopic torsion spring 203 is located inside the clamping groove 103, and the bottom end of the support rod 201 and the bottom end of the clamping groove 103 The top end of the telescopic torsion spring 203 is fixedly connected to the clamping block 202, and the bottom end of the telescopic torsion spring 203 is fixedly connected to the clamping groove 103. The clamping block 202 is provided with a bolt contact groove 2023 near the fixing nut 1013, and a parallel clamping groove 2024 is provided at the bolt contact groove 2023 of the clamping block 202. Diagonal clamping grooves 2025 are provided in the middle of both sides of the parallel clamping groove 2024. A limiting block 2011 is provided at the top end of the side of the support rod 201 away from the reducer base 1, and a limiting groove 2022 is provided on the side of the rotating groove 2021 of the clamping block 202 near the bolt contact groove 2023. The limiting block 2011 and the limiting groove 2022 can be movably clamped, and the clamping block 202 is connected by parallel clamping. The groove 2024 or the diagonal groove 2025 can limit the position of the fixing nut 1013. Since the fixing bracket bolt 1011 is generally fixed by the support frame, it can only be fixed by rotating the fixing nut 1013. If the fixing nut 1013 cannot be limited by using the parallel groove 2024 or the diagonal groove 2025, the tightening position of the fixing nut 1013 is improved by adding a gasket at the bottom end of the fixing nut 1013, and the number of rotations is changed, so that the parallel groove 2024 or the diagonal groove 2025 can limit the position of the fixing nut 1013. Both sides of the reducer base 1 are provided with device fixing holes 104, and the top of the device fixing hole 104 is installed with an oil injection device 3.The bottom end of the oil injection device 3 is provided with drip oil grooves arranged at equal intervals. Leakage pipes 302 are installed in the drip oil grooves of the oil injection device 3. Liquid blocking "C"-shaped grooves 305 are installed on the inner wall of the oil injection device 3 at the top ends of the leakage pipes 302. The bottom end of the liquid blocking "C"-shaped groove 305 is 3 mm lower than the top end of the leakage pipe 302, which can prevent the top end of the leakage pipe 302 from directly contacting the waste oil in the oil injection device 3. Instead, it sucks oil through the area defined by the liquid blocking "C"-shaped groove 305 for discharge, enabling the leakage pipe 302 to suck oil without sucking debris in the oil. The oil injection device 3 is arranged in an inclined shape. A debris collection pipe 4 is installed at the bottom side of the inclined end of the oil injection device 3. An oil injection pipe 5 is installed outside the top end of the inclined end of the oil injection device 3. The bottom end of the leakage pipe 302 is provided with a drip pipe 3021. A leakage spring 304 is installed on the inner wall of the leakage pipe 302 at the drip pipe 3021. The bottom end of the leakage spring 304 is fixedly connected to the inner wall of the drip pipe 3021. The top end of the leakage spring 304 is fixedly connected to a leakage bead 303. The leakage pipe 302 is provided with a leakage groove 3022 for the leakage bead 303 at the position where the leakage bead 303 is located. The top end of the leakage spring 304 can expand and contract in the drip pipe 3021 and the leakage groove 3022. The leakage bead 303 can move in the leakage groove 3022 and the leakage pipe 302. The bottom end of the drip pipe 3021 is provided with a drip opening, and the drip opening of the drip pipe 3021 is directly opposite the middle of the top end of the fixed support screw 1012. The top end of the debris collection pipe 4 is provided with a ball valve pipe 401. A collection ball valve 402 is installed in the ball valve pipe 401. The top end of the debris collection pipe 4 is fixedly connected to the bottom end of the oil injection device 3. The top end of the debris collection pipe 4 communicates with the bottom end of the lowest part of the inclined end of the oil injection device 3. The bottom end of the debris collection pipe 4 is connected with a sealing block 403 through a hinge. Silicone pads that fit the inner wall of the debris collection pipe 4 are fixedly connected to the top ends of the sealing block 403. A buckle 404 is installed on the other side of the hinge of the debris collection pipe 4 where the sealing block 403 is located. The sealing block 403 hermetically seals the bottom end of the debris collection pipe 4 through the buckle 404 and the silicone pad. A collection observation window 405 is opened on the outer side of the debris collection pipe 4 away from the reducer base 1. A plug 501 is installed at the top end of the oil injection pipe 5. A ventilation hole is opened at the top end of the plug 501. Lubricating oil is filled into the oil injection pipe 5 or the waste lubricating oil after overhauling the reducer by opening the plug 501 in the oil injection device 3. It can not only utilize the waste oil but also collect the metal debris in the waste lubricating oil for recycling. An oil injection observation window 301 is opened on the outer wall of one end of the oil injection device 3 where the debris collection pipe 4 is located, for observing the liquid level height. When the liquid level reaches the bottom end of the oil injection observation window 301, it means that waste oil needs to be added. If it is higher, it means that the liquid level is sufficient.,

[0027] The working principle of the present invention: When installing, first, move the clamping block 202 and pull it up. At this time, the telescopic torsion spring 203 is stretched and twisted at the same time. After the clamping block 202 is rotated, ensure that the limiting groove 2022 of the clamping block 202 is located at the bottom end of the limiting block 2011. At this time, the clamping block 202 is continued to be pulled up, so that the limiting groove 2022 of the clamping block 202 is inserted into the limiting block 2011 of the support rod 201. At this time, the limiting of the clamping block 202 is completed. At this time, align the fixing nut 1013 of the reducer base 1 with the fixing bracket screw 1012 of the support frame. After alignment, installation is carried out at this time. Use a wrench to install the fixing nut 1013 into the fixing bracket screw 1012 to achieve the reducer base. 1. After being completely fixed, the clamping block 202 is pressed down, and the telescopic torsion spring 203 releases the tension and torsion force, so that the bolt contact groove 2023 rebounds to resist the fixing bracket screw 1012 at the top of the fixing nut 1013. At this time, according to the position of the fixing nut 1013, when rebounding, the parallel clamping groove 2024 of the clamping block 202 just clamps the two parallel sides of the fixing nut 1013. Due to the limitation of the fixing nut 1013 by the parallel clamping groove 2024, the fixing nut 1013 cannot be rotated, so as to prevent the fixing nut 1013 from rotating due to vibration, so that it will not rotate after installation, ensuring the stability after installation; When the parallel slots 2024 are not exactly inserted into the two parallel sides of the fixing nut 1013 during installation, the clamping block 202 is lifted up and the diagonal slots 2025 of the clamping block 202 are inserted into the two diagonal corners of the fixing nut 1013 to complete the limited installation. During use, since the fixing bracket bolt 1011 is fixed to the support frame and cannot rotate, the parallel slots 2024 and the diagonal slots 2025 limit the fixing nut 1013, so that the fixing nut 1013 and the fixing bracket screw 1012 will not rotate under vibration, which greatly improves the limited fixing effect. After the installation is completed, the sealing plug 501 of the oil filling pipe 5 is opened, and the waste oil after the speed reducer is repaired or other waste oil is poured in. After the pouring is completed, the oil filling pipe 5 is closed through the sealing plug 501. After the sealing plug 501 is closed, the speed reducer can be operated. When the speed reducer is in operation, due to the limitation of the liquid-blocking "C"-shaped groove 305, the liquid leakage pipe 302 can only suck the waste oil located at the top of the liquid leakage pipe 302 and within the liquid-blocking "C"-shaped groove 305. Since the position of the waste oil within the liquid-blocking "C"-shaped groove 305 is relatively high, under the action of vibration and gravity, there will be no debris in the waste oil that enters the oil in the liquid leakage pipe 302. As the speed reducer vibrates, the liquid leakage spring 304 will expand and contract. When expanding and contracting, the liquid leakage beads 303 will break away from the liquid leakage groove 3022, and the liquid leakage beads 303 will release the blockage of the liquid leakage groove 3022, causing the waste oil within the oil injection device 3 to flow into the drip pipe 3021 through the gap between the liquid leakage beads 303 and the liquid leakage pipe 302. Due to the pulling force of the liquid leakage spring 304, the time for the liquid leakage beads 303 to release the blockage of the liquid leakage groove 3022 is short, resulting in a small amount of oil entering the drip pipe 3021. Subsequently, it drips through the drip orifice of the drip pipe 3021 onto the top of the fixed support screw 1012, thereby dripping onto the fixed support screw 1012. After dripping, the oil droplets that drip onto the fixed support screw 1012 will slowly accumulate at the fixed support screw 1012 and the fixed nut 1013, and then slowly penetrate into the entire fixed support screw 1012 from the fixed nut 1013, thereby reducing the friction between the fixed support bolt 1011 and the fixed support screw 1012 during the operation of the speed reducer. At the same time, it can prevent the threads on the surface of the subsequent fixed support screw 1012 and the inner threads of the fixed nut 1013 from rusting, ensuring the service life of the fixed support screw 1012, and at the same time ensuring later disassembly and installation. When in use, since waste oil or waste oil after the speed reducer chassis is overhauled is used, during vibration, the debris in the waste oil will move towards the low-end debris collection pipe 4, and thus fall to the debris collection pipe 4. First, it enters between the collection ball valve 402 of the debris collection pipe 4 and the plugging block 403 through the collection ball valve 402. As the debris accumulates, after it is known through observing the collection observation window 405 that the debris reaches a certain thickness, at this time, by opening the buckle 404, after opening the buckle 404, the debris converging in the debris collection pipe 4 will be collected, enabling the metal in the debris to be recycled.

[0028] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
