Description

Technical Field

[0001] This utility model relates to the field of engineering components or parts technology, and in particular to a device for removing a recyclable motor shaft sleeve from a large coil. Background Technology

[0002] In the field of mechanical repair and assembly, bushings are commonly used matching parts for key components such as motors and transmission equipment. Their disassembly is an important part of the equipment maintenance process. The bushings are often fitted with components such as motor shafts using interference fits to ensure the stability and reliability of the equipment during operation.

[0003] In traditional bushing removal devices, the grippers and bushings are rigidly connected. When a pulling force is applied to disassemble the bushing, the rigid grippers easily form a hard contact with the bushing surface. Due to the variety of bushing materials, some bushings are made of softer alloys or non-metallic materials. Under the pulling force of the hard contact, the bushing surface is very prone to scratches, deformation and other damage. This not only affects the recyclability of the bushing, but may also lead to a decrease in the fitting accuracy with the motor shaft during subsequent reassembly due to bushing deformation, thus affecting the overall performance of the equipment. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a large-coil recyclable motor bushing removal device. This device solves the problem that the contact part between the gripper and the bushing is rigidly connected. When the bushing is disassembled by applying a pulling force, the rigid gripper is prone to hard contact with the bushing surface. Since the bushing is made of various materials, some bushings are made of softer alloy or non-metallic materials. Under the pulling force of hard contact, the bushing surface is very easy to be scratched, deformed and damaged. This not only affects the recyclability of the bushing, but may also lead to a decrease in the fitting accuracy with the motor shaft during subsequent reassembly due to bushing deformation, thus affecting the overall performance of the equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a large coil recyclable motor bushing removal device, comprising a drive screw, a crossbeam, a first positioning base and a second positioning base, wherein the interior of the first positioning base and the second positioning base is provided with an elastic rubber component; The elastic rubber assembly includes an elastic rubber component and a positioning slide. When the elastic rubber component is a planar elastic rubber pad, the positioning slide is fixedly installed on the outer wall of the elastic rubber component. The inner walls of the first positioning base and the second positioning base are both provided with elastic rubber component mounting grooves. The outer wall of the elastic rubber component is slidably connected to the interior of the corresponding elastic rubber component mounting groove. The inner walls of the two elastic rubber component mounting slots are provided with positioning grooves, and magnetic seats are fixedly installed on the inner walls of the two positioning grooves. Magnetic blocks are fixedly installed on the outer walls of the positioning slides. The upper and lower outer walls of the first and second positioning bases are threaded with two fixing bolts, and the upper and lower outer walls of the elastic rubber component are provided with fixing bolt grooves.

[0006] Preferably, the outer wall of the positioning slide is slidably connected to the interior of the corresponding positioning groove.

[0007] Preferably, the outer wall of the magnetic block near the magnetic base is attracted to the magnetic base.

[0008] Preferably, the eight fixing bolts are arranged in groups of four, and the end of each group of fixing bolts near the fixing bolt groove extends into the interior of the elastic rubber component mounting groove and is respectively connected to the internal thread of the corresponding fixing bolt groove.

[0009] Preferably, the crossbeam is threaded onto the outer wall of the drive screw, and two fixing rods are fixedly connected to the left and right outer walls of the crossbeam.

[0010] Preferably, two connecting rods are fixedly connected to the upper surfaces of both the first positioning base and the second positioning base.

[0011] Preferably, the ends of the four connecting rods away from the first positioning base are respectively slidably connected to the outside of the corresponding fixed rod, and connecting bolts are installed on the left and right outer walls of the first positioning base.

[0012] Preferably, the end of the connecting bolt away from the first positioning base is bolted to the second positioning base.

[0013] Preferably, when both elastic rubber components are strip-groove elastic rubber pads, the two strip-groove elastic rubber pads are installed inside the first positioning base and the second positioning base respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This large coil reusable motor bushing removal device uses elastic rubber components (including flat elastic rubber pads and grooved elastic rubber pads) installed inside the first and second positioning bases of the elastic rubber assembly. During the bushing removal operation, the elastic rubber components can flexibly contact the bushing surface. When the drive screw drives the crossbeam, and then pulls the positioning base assembly (first positioning base and second positioning base) through the fixed rod and connecting rod to remove the bushing, the elastic rubber components effectively buffer the pulling impact by utilizing their own elastic deformation.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0020] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0021] Example 1: Reference Figure 1-4 A basic embodiment of conventional bushing disassembly (planar elastic rubber pad + magnetic positioning). Suitable for disassembling standard motor bushings with smooth surfaces and standard dimensions. The elastic rubber parts use ordinary flat elastic rubber pads with uniform texture, which can provide basic cushioning and friction. The positioning slide is positioned by magnetic attraction blocks and magnetic seats in the positioning groove, ensuring accurate installation. When disassembling the bushing, the flat elastic rubber pad fits tightly against the outer wall of the bushing. Under the pull of the drive screw, the friction of the rubber drives the bushing to detach. The fixing bolts reinforce the connection. The operation is simple and suitable for small and medium-sized motor repair scenarios.

[0022] Example 2: Reference Figure 5 Special-shaped bushing adapter embodiment (deformable strip groove elastic rubber pad + flexible positioning slide) For disassembling non-circular or irregularly shaped bushings, the elastic rubber component uses a strip-groove elastic rubber pad. The groove structure can adapt to the shape of the bushing. The positioning slide is made of a flexible material that can deform with the rubber pad. When disassembling irregularly shaped bushings, the strip-groove rubber pad is embedded in the concave and convex parts of the bushing, the flexible positioning slide keeps it in contact, and the magnetic seat assists in positioning, so as to achieve stable gripping and disassembly of bushings with special shapes and meet the special motor maintenance needs.

[0023] Furthermore, when using this device, before removing the device using the large recyclable motor bushing, the assembly of the device and the installation of the elastic rubber component 8 must be completed first. Taking the installation of the planar elastic rubber component 8 as an example, firstly, align the positioning slide 14 on the outer wall of the elastic rubber component 8 with the positioning groove 12 in the elastic rubber component mounting groove 16 on the inner wall of the first positioning base 5 and the second positioning base 9. Since the magnetic block 10 on the outer wall of the positioning slide 14 and the magnetic seat 13 on the inner wall of the positioning groove 12 have an adsorption effect, the elastic rubber component 8 can be initially positioned in the elastic rubber component mounting groove 16 under the magnetic attraction. At this time, the positioning slide 14 slides along the positioning groove 12 to achieve the pre-installation of the elastic rubber component 8. Then, pass the fixing bolt 6 through the first positioning base 5 and the second positioning base 9. The threaded holes on the upper and lower outer walls of the base 9 are screwed into the fixing bolt grooves 11 on the upper and lower outer walls of the elastic rubber component 8. Through threaded connection, the elastic rubber component 8 is firmly fixed in the elastic rubber component mounting groove 16. If a strip-shaped groove elastic rubber pad 15 is used, it is installed inside the first positioning base 5 and the second positioning base 9 according to the corresponding structure and installation method. After the elastic rubber assembly is installed, the first positioning base 5 and the second positioning base 9 are connected into a whole by connecting bolts 7. At this time, the ends of the four connecting rods 4 away from the first positioning base 5 are respectively slidably engaged with the external parts of the corresponding fixing rods 3. The crossbeam 2 is threaded onto the outer wall of the drive screw 1. The entire device is assembled. Then, the assembled device is sleeved on the outside of the motor shaft sleeve, so that the first positioning base 5 and the second positioning base 9 are properly aligned. The elastic rubber component 8 (flat elastic rubber pad or strip groove elastic rubber pad 15) inside the base 9 contacts the outer wall of the motor bushing. Due to the elasticity of the elastic rubber component 8, a certain degree of elastic deformation occurs during contact. On one hand, the reaction force generated by the elastic deformation allows the elastic rubber component 8 to fit tightly against the outer wall of the motor bushing, increasing the friction between them and preventing slippage during subsequent removal. On the other hand, the elastic buffering effect avoids damage to the motor bushing caused by rigid contact, ensuring the recyclability of the bushing. By adjusting the device position, the elastic rubber component 8 is evenly wrapped around the outer wall of the motor bushing, achieving stable clamping of the bushing. Then, the drive screw 1 is rotated. Since the crossbeam 2 is threaded onto the outer wall of the drive screw 1, under the action of the threaded transmission, the crossbeam 2... Beam 2 moves axially along the drive screw 1, and the fixing rods 3 on the left and right outer walls of beam 2 move accordingly. Through sliding engagement with connecting rod 4, they drive the first positioning base 5 and the second positioning base 9 to move synchronously along the drive screw 1. At this time, the elastic rubber parts 8 inside the first positioning base 5 and the second positioning base 9 are tightly attached to the outer wall of the motor bushing. As the positioning base assembly moves away from the motor shaft, the friction between the elastic rubber parts 8 and the motor bushing, as well as the pulling force of the device, work together to pull the motor bushing out of the motor shaft. During the pulling process, the elastic rubber parts 8 continuously provide elastic cushioning, absorbing the possible impact force and preventing the bushing from being deformed, scratched, or damaged during removal. At the same time, the friction between them and the bushing ensures the effective transmission of the pulling force.This allows the bushing to be removed smoothly and easily.

[0024] By setting up an elastic rubber assembly (including an elastic rubber component 8, which includes a flat elastic rubber pad and a strip-groove elastic rubber pad 15) inside the first positioning base 5 and the second positioning base 9 of the elastic rubber assembly, the elastic rubber component 8 can flexibly contact the surface of the bushing during the bushing removal operation. When the drive screw 1 drives the crossbeam 2, and then pulls the positioning base assembly (first positioning base 5 and second positioning base 9) through the fixed rod 3 and the connecting rod 4 to remove the bushing, the elastic rubber component 8 uses its own elastic deformation to effectively buffer the impact of the pulling force. Compared with the hard contact of traditional rigid claws, it can avoid scratches and deformation on the surface of the bushing due to instantaneous stress concentration, and can preserve its original shape to the greatest extent.

[0025] Structural Description: Drive screw 1: As the core power transmission component, it provides axial tension or thrust for the entire extraction device. Its outer wall is threaded and can be engaged with the threaded hole of the crossbeam 2. By rotating the drive screw 1, the crossbeam 2 can be moved along the axial direction of the drive screw 1.

[0026] The crossbeam 2 serves to transmit and distribute force. It is threaded onto the outer wall of the drive screw 1 and transmits the power of the drive screw 1 to the fixed rod 3, thereby driving the entire positioning base assembly (first positioning base 5 and second positioning base 9) to move. The two fixed rods 3 fixedly connected to its left and right outer walls provide an installation base for cooperation with the connecting rod 4.

[0027] Fixed rod 3: It is fixedly connected to the crossbeam 2 and is used to slide with the connecting rod 4. It guides the movement of the first positioning base 5 and the second positioning base 9, and ensures that the positioning base assembly moves smoothly along the axial direction of the drive screw 1. The four fixed rods 3 are respectively slidably connected to the corresponding connecting rod 4.

[0028] Connecting rod 4: One end is fixedly connected to the upper surface of the first positioning base 5 and the second positioning base 9, and the other end is slidably connected to the outside of the fixing rod 3. Together with the fixing rod 3, they restrict the movement direction of the first positioning base 5 and the second positioning base 9, so that the positioning base assembly moves synchronously along the drive screw 1 with the crossbeam 2.

[0029] First positioning base 5: It is the basic component for positioning and installing elastic rubber components. It cooperates with second positioning base 9 to clamp and position the motor shaft sleeve. It has an elastic rubber component mounting groove 16 inside for installing elastic rubber component 8. The connecting bolts 7 installed on the left and right outer walls can realize the bolt connection with the second positioning base 9. The fixing bolts 6 threaded on the upper and lower outer walls are used to fix the elastic rubber component 8.

[0030] Fixing bolts 6: There are eight fixing bolts 6 in total, in groups of four. One end of a group of fixing bolts 6 near the fixing bolt groove 11 extends into the interior of the elastic rubber component mounting groove 16 and is threadedly connected to the fixing bolt groove 11 on the elastic rubber component 8, thereby fixing the elastic rubber component 8 in the elastic rubber component mounting groove 16 of the first positioning base 5 and the second positioning base 9.

[0031] Connecting bolt 7: Installed on the left and right outer walls of the first positioning base 5, with the end furthest from the first positioning base 5 connected to the second positioning base 9 by bolts, used to connect the first positioning base 5 and the second positioning base 9 into a whole, ensuring that the two move synchronously and work together during operation.

[0032] Elastic rubber component 8: It comes in two forms: flat elastic rubber pad and strip groove elastic rubber pad 15. It is a key component for achieving elastic buffering and protecting the motor bushing. It is installed inside the first positioning base 5 and the second positioning base 9. By contacting the motor bushing, it provides elastic buffering during the removal process to avoid damage to the bushing, while increasing friction and preventing slippage.

[0033] The second positioning base 9 has a similar structure and function to the first positioning base 5, and together they form a positioning base assembly. It also has an elastic rubber assembly inside, and is connected to the first positioning base 5 by connecting bolts 7, so as to complete the clamping and removal of the motor shaft sleeve.

[0034] Magnetic block 10: It is fixedly installed on the outer wall of the positioning slide 14. The outer wall of the side near the magnetic seat 13 is attracted to the magnetic seat 13. During the installation of the elastic rubber part 8, it plays a role in pre-positioning, which facilitates the installation of the elastic rubber part 8 with the positioning slide 12 and the fixing bolt 6. At the same time, it helps to maintain the positional stability of the elastic rubber part 8 during the operation.

[0035] Fixed bolt groove 11: It is formed on the upper and lower outer walls of the elastic rubber part 8 and is used to connect with the fixed bolt 6 by thread to fix the elastic rubber part 8 in the elastic rubber part mounting groove 16, so as to ensure that the elastic rubber part 8 will not shift when working.

[0036] Positioning groove 12: It is formed on the inner wall of the elastic rubber part mounting groove 16, providing a sliding track for the positioning slide 14, restricting the movement direction of the positioning slide 14, and thus ensuring that the elastic rubber part 8 slides and is installed in the elastic rubber part mounting groove 16 in a predetermined direction.

[0037] Magnetic base 13: It is fixedly installed on the inner wall of the positioning slide groove 12 and is attracted and cooperated with the magnetic block 10 to pre-position the elastic rubber part 8, so as to facilitate the installation and initial fixation of the elastic rubber part 8.

[0038] Positioning slide 14: It is fixedly installed on the outer wall of the elastic rubber part 8. Its outer wall is slidably connected to the inside of the positioning slide groove 12. In conjunction with the positioning slide groove 12, magnetic seat 13, and magnetic block 10, it realizes the precise installation and positioning of the elastic rubber part 8 in the elastic rubber part mounting groove 16, ensuring the accuracy of the working position of the elastic rubber part 8.

[0039] The strip-groove elastic rubber pad 15 is a specific form of the elastic rubber part 8, which is installed inside the first positioning base 5 and the second positioning base 9. Compared with the planar elastic rubber pad, the strip-groove structure can be adapted to motor bushings of specific shapes and sizes, increasing the contact area and friction, while providing elastic cushioning.

[0040] Elastic rubber component mounting groove 16: formed on the inner wall of the first positioning base 5 and the second positioning base 9, used to accommodate and install the elastic rubber component 8, providing installation space and positioning foundation for the elastic rubber component 8.

[0041] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
