[0001] This utility model relates to the field of speed reducer repair technology, and in particular to a positioning device for speed reducer repair. Background Technology

[0002] The main function of a speed reducer is to reduce the input speed and increase the output torque. It is an indispensable component in many mechanical systems. A speed reducer is mainly composed of a motor and a reduction gear set. When performing maintenance, the motor and the reduction gear set need to be separated. After maintenance, the motor shaft is aligned with the inside of the reduction gear set, and then reassembled.

[0003] After the speed reducer is repaired, the motor and the reduction gear set need to be assembled. The motor usually needs to be transported by gantry crane. However, the motor is prone to shaking during the transportation process by gantry crane. At this time, it is difficult for the motor to be connected with the reduction gear set. The assembly of the speed reducer takes a long time. Therefore, this application provides a positioning device for speed reducer repair to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a positioning device for speed reducer maintenance to solve the problem that it takes a long time to assemble speed reducers using a gantry crane.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A positioning device for speed reducer maintenance includes a placement base, the top of which has a positioning groove, and a movable base is inserted into the positioning groove.

[0007] The positioning assembly includes four positioning blocks disposed on the top of the placement seat. Each of the four positioning blocks has a groove on its bottom. The positioning blocks are fixed to the support of the reducer by being engaged in the groove. A screw rod is threaded through the side of the placement seat, and the end of the screw rod is rotatably connected to the side of the positioning block.

[0008] The support assembly includes a support base fixed to the top of the movable seat. The support base has an inner cavity 1, an inner cavity 2, and a flow channel inside. The inner cavity 1 is connected to the flow channel, and the flow channel is connected to the inner cavity 2. A drive piston is slidably connected inside the inner cavity 1. A screw 2 is rotatably connected to the top of the drive piston. The screw 2 is threaded through the top of the support base. A driven piston is slidably connected inside the inner cavity 2. A connecting block is fixed to the top of the driven piston. The connecting block movably passes through the top of the support base and fixes a support platform thereon.

[0009] Preferably, a placement guide surface is provided at the top edge of the placement seat.

[0010] Preferably, the inner wall of the groove has a top guide surface.

[0011] Preferably, the side of the groove is provided with a side guide surface.

[0012] Preferably, a guide rod is movably passed through the side of the placement seat, and the guide rod is fixed to the side of the positioning block.

[0013] Preferably, a guide rod two is fixed to the top of the drive piston, the guide rod two movably passes through the top of the support base, and the guide rod two is arranged parallel to the screw two.

[0014] Preferably, the top of the support platform is provided with a curved groove, the inner wall of the curved groove is fixed with a support pad, and the surface of the support pad is provided with anti-slip stripes.

[0015] Preferably, the bottom of the placement seat is fixed with a support leg, the top of the movable seat is fixed with a handrail, and the bottom of the movable seat is fixed with a caster wheel, the lowest point of the caster wheel being in the same plane as the bottom of the support leg.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, by setting up a placement seat and a positioning component, the positioning component can accurately position the reduction gear set of the reducer. The four positioning blocks, through the cooperation of the bottom groove with the reducer support, can effectively limit the position of the gear set and ensure that it will not be displaced during maintenance. When checking or replacing gear wear, stable positioning can enable maintenance personnel to operate tools more accurately, improve maintenance accuracy, reduce maintenance errors caused by inaccurate positioning, and ensure that the performance of the reducer is restored to a good state after maintenance.

[0018] By setting up a movable base and support components, the support components on the movable base provide stable support for the reducer motor. The support platform can be height adjusted according to the shape and size of the motor to adapt to the support requirements of different motor models. Moreover, the casters at the bottom of the movable base make it easy to remove and move the motor flexibly. In the case of limited maintenance space, the operating area can be effectively cleared to avoid the motor from obstructing the maintenance of the gear set. When the maintenance is completed and the motor needs to be installed, it can be easily moved back to its original position to achieve quick installation and improve maintenance efficiency.

[0019] The curved grooves on the top of the support platform and the support pads with anti-slip stripes not only better fit the shape of the motor, but also effectively prevent the motor from slipping during the support process. This provides reliable stability and safety when the motor may need to be flipped or inspected during maintenance, avoiding accidental damage to the motor and ensuring the safety of maintenance personnel.

[0020] The screw one in the positioning assembly allows for easy adjustment of the positioning block's position to accommodate the fixing requirements of different specifications of reducer supports. By rotating screw one, the positioning block can be precisely moved on the placement seat, making the operation simple and quick. Similarly, the design of screw two in the support assembly makes the process of the drive piston driving the driven piston and thus adjusting the height of the support platform easy and controllable. Maintenance personnel can quickly adjust to the appropriate support height according to the actual situation, saving maintenance time and effort. Attached Figure Description

Detailed Implementation

[0031] The positioning device for speed reducer maintenance provided by this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0032] like Figures 1-6 As shown, this utility model provides a positioning device for speed reducer maintenance, including a placement base 1. The placement base 1 is the basic platform of the entire positioning device, supporting other components and providing a stable installation foundation. Its positioning groove 3 provides guidance and limit for the movement and positioning of the movable seat 2, ensuring the stability of the entire device structure. This allows maintenance operations to be carried out on a reliable basis, reducing maintenance errors caused by foundation shaking or instability, and improving maintenance accuracy and safety. The top of the placement base 1 has a positioning groove 3, and the movable seat 2 is inserted into the positioning groove 3. The movable seat 2 can move flexibly within the positioning groove 3 of the placement base 1. Together with the support component 13, it supports and moves the speed reducer motor. During maintenance, the motor can be easily moved away or back to its original position, facilitating the separation and combination of the motor and the speed reduction gear set. This allows maintenance personnel to perform maintenance operations on the speed reduction gear set more easily, saving maintenance time and manpower and improving maintenance efficiency.

[0033] The positioning component 6 includes four positioning blocks 7 mounted on the top of the placement base 1. Each of the four positioning blocks 7 has a groove 10 at its bottom. The positioning blocks 7 are secured to the reducer support via the grooves 10. A screw 8 is threaded through the side of the placement base 1, and the end of the screw 8 is rotatably connected to the side of the positioning blocks 7. Through the cooperation of the grooves 10 at the bottom of the four positioning blocks 7 with the reducer support, precise positioning and fixation of the reduction gear set are achieved. The screw 8 can adjust the position of the positioning blocks 7, ensuring that the position of the reduction gear set remains fixed during maintenance, facilitating gear inspection and replacement, and improving maintenance quality. The adjustable function of the screw 8 allows the device to adapt to reducers of different specifications, enhancing its versatility.

[0034] Support assembly 13 includes a support base 14 fixed to the top of the movable base 2. The support base 14 has an inner cavity 15, an inner cavity 20, and a flow channel 19. The inner cavities 15, 20, and 19 are filled with hydraulic oil. The inner cavity 15 communicates with the flow channel 19, and the flow channel 19 communicates with the inner cavity 20. A drive piston 16 is slidably connected inside the inner cavity 15. A screw 17 is rotatably connected to the top of the drive piston 16. The screw 17 is threaded through the top of the support base 14. The inner cavity 20... An internally sliding piston 21 is connected, and a connecting block 22 is fixed to the top of the driven piston 21. The connecting block 22 moves through the top of the support base 14 and fixes a support platform 23. Using the hydraulic principle, the driven piston 16 moves under the action of the screw 17, which drives the driven piston 21, thereby raising and lowering the support platform 23 to adapt to motors of different heights and provide stable support. The support height can be precisely adjusted to meet the support requirements of various motors, ensuring that the motor is placed stably during maintenance and avoiding motor damage or maintenance accidents caused by unstable support.

[0035] like Figure 2 As shown in this embodiment, a placement guide surface 25 is provided at the top edge of the placement seat 1. When the speed reducer is placed into the placement seat 1, it provides guidance for the speed reducer, so that it can enter the placement seat 1 more smoothly. This simplifies the placement operation of the speed reducer, reduces the collision and wear on the device components during the placement process, and improves the operating efficiency and service life of the device.

[0036] like Figure 5 As shown, in this embodiment, a top guide surface 11 is provided on the top of the inner wall of the groove 10. The top guide surface 11 is used to quickly lock the positioning block 7 onto the top of the support. The inclined top guide surface 11 can adapt to supports of different thicknesses and is more widely used.

[0037] like Figure 5 As shown, in this embodiment, a side guide surface 12 is provided on the side of the groove 10. The positioning block 7 moves toward the support of the reduction gear set of the reducer. The positioning block 7 is guided by the side guide surface 12, and the support can slide along the side guide surface 12, so that the reducer is better positioned in the middle of the placement seat 1.

[0038] like Figure 2 As shown in this embodiment, a guide rod 9 is movably passed through the side of the placement seat 1. The guide rod 9 is fixed to the side of the positioning block 7. The guide rod 9 provides linear guidance for the movement of the positioning block 7, ensuring that the positioning block 7 moves stably along a straight line under the drive of the screw 8, avoiding deviation or shaking, and improving the stability and accuracy of positioning.

[0039] like Figure 3As shown, in this embodiment, a guide rod 18 is fixed to the top of the drive piston 16. The guide rod 18 extends through the top of the support base 14. The guide rod 18 is arranged parallel to the screw 17. The guide rod 18 provides linear guidance for the movement of the drive piston 16, preventing the drive piston 16 from rotating or deviating when the screw 17 rotates, ensuring the accuracy of the linear movement of the drive piston 16, thereby ensuring the accuracy and stability of the height adjustment of the support platform 23.

[0040] like Figure 2 As shown in this embodiment, the top of the support platform 23 is provided with a curved groove, the shape of which is adapted to the shape of the motor, providing a fitting surface for the motor, increasing the stability of the motor placement, and preventing the motor from rolling or shifting on the support platform 23. The inner wall of the curved groove is fixed with a support pad 24, and the surface of the support pad 24 is provided with anti-slip stripes, which provide cushioning and increase friction, protecting the motor housing from damage. At the same time, the anti-slip stripes further prevent the motor from slipping during maintenance, ensuring the safety of maintenance operations.

[0041] like Figure 2 and Figure 4 As shown, in this embodiment, the bottom of the placement seat 1 is fixed with a support leg, which provides stable support for the placement seat 1, keeping it stable on the ground and ensuring that the entire device is placed stably, providing a reliable basic environment for maintenance operations. The top of the movable seat 2 is fixed with a handrail 5, which makes it convenient for operators to push the movable seat 2, making the movement of the movable seat 2 more convenient and labor-saving, improving the comfort and efficiency of operation. The bottom of the movable seat 2 is fixed with a universal wheel 4, which allows the movable seat 2 to move flexibly, making it easy to quickly move the motor away or back during maintenance. In conjunction with the handrail 5, it realizes efficient motor displacement operation. Moreover, the lowest point of the universal wheel 4 is in the same plane as the bottom of the support leg, ensuring the stability of the movable seat 2 when moving and stationary.

[0042] Working principle: First, place the entire positioning device in a suitable maintenance work area, ensuring that the support legs at the bottom of the placement base 1 are stably on the ground. Check whether each component of the positioning assembly 6 and the support assembly 13 is in normal condition, such as whether screw 1 8 and screw 2 17 can rotate flexibly, and whether guide rod 1 9 and guide rod 2 18 can move normally, etc.

[0043] The speed reducer is hoisted or transported to the placement seat 1, and then slowly placed into the placement seat 1 along the placement guide surface 25. Then, by rotating the screw 8, the screw 8 drives the positioning block 7 to move under the guidance of the guide rod 9, so that the groove 10 of the positioning block 7 tightly locks into the support of the speed reducer, thereby completing the precise positioning of the speed reduction gear set;

[0044] Loosen the connection between the motor and the reduction gear set, and remove the motor from the reducer. Then, push the movable seat 2 using the handle 5 on top of the movable seat 2, and use the casters 4 at the bottom of the movable seat 2 to move it away from the area of ​​the reduction gear set under maintenance, providing ample operating space for maintenance personnel to facilitate comprehensive inspection, maintenance or replacement of parts of the reduction gear set;

[0045] After the motor is removed, maintenance personnel can conduct a detailed inspection of the positioned reduction gear set, such as checking the wear of the gears, the flatness of the tooth surfaces, and the meshing between the gears. For any problems found, such as severely worn gears requiring replacement, precise disassembly and installation can be performed using maintenance tools. Because the reduction gear set is now stably positioned, the operation is safer and more efficient.

[0046] After the reduction gear set is repaired, push the movable seat 2 back to its original position using the handle 5, bringing the motor closer to the reduction gear set. Based on the required motor installation height, rotate screw 17. Screw 17 drives the drive piston 16 to move within inner cavity 15 under the guidance of guide rod 18. The movement of the drive piston 16 is transmitted through hydraulic oil in flow channel 19, causing the driven piston 21 to move accordingly within inner cavity 20. This, in turn, raises or lowers the connecting block 22 and support platform 23. After adjusting to the appropriate height, connect and install the motor and reduction gear set, completing the entire repair and installation process of the reducer.

[0047] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.
