Description

Technical Field

[0001] This utility model relates to the technical field of rotating sleeves, specifically a quick-assembly and disassembly structure for a rotating bushing. Background Technology

[0002] Rotary bushings are widely used in various mechanical equipment, and their installation and disassembly are crucial for equipment maintenance and component replacement. Currently, traditional methods of installing and disassembling rotary bushings have several drawbacks. Firstly, bushings and shafts or mounting components often use an interference fit, requiring significant external force during installation. This not only makes operation difficult but also easily damages the bushing, shaft, and other related components due to improper handling. For example, using a sledgehammer to strike a copper rod to install bushings in small equipment is not only laborious but can also damage the bushing or mounting component due to uneven striking force. Secondly, the disassembly process is equally challenging. Due to long-term use, bushings are affected by factors such as media impurities, temperature changes, and O-ring aging, which can lead to blockages, coking, rust, and adhesion between the bushing and shaft, greatly increasing the difficulty of disassembly. In some pump and motor equipment, due to the small step clearance between the bushing and shaft, commonly used hydraulic pullers are ineffective, necessitating destructive removal methods such as cutting machines or gas cutting. This undoubtedly severely damages the bushing and shaft, reduces component lifespan, and increases maintenance costs. Furthermore, for some power machinery that requires frequent disassembly and assembly of bushings during testing, such as electric motors, compressors, pumps, and fans, each disassembly of a traditional bushing involves removing a large number of connecting bolts, which significantly prolongs test preparation time and reduces work efficiency. In certain specific equipment such as rotating wedges, the traditional integrated rotating bushing requires removing the bolts and lifting the entire reset block and bushing during reset block disassembly, which is cumbersome and poses a risk of bushing detachment, damage, and injury. Therefore, developing a rotating bushing structure that enables rapid, convenient, and non-destructive disassembly and assembly is of significant practical importance.

[0003] Application number CN201721525699.9 discloses a quick-assembly / disassembly structure, including a hollow connecting shaft, a rotating shaft, and an outer sheath. Positioning beads one and two are symmetrically installed radially on the connecting shaft, and springs one and two are respectively installed between the positioning beads one and two and the connecting shaft. The connecting shaft passes through the rotating shaft, with a boss at the end of the connecting shaft abutting against the top opening of the rotating shaft. The bottom thread of the connecting shaft is fixedly connected to a positioning ring located below the rotating shaft. A positioning rod is provided radially inside the rotating shaft, passing through the connecting shaft and a positioning block inside the connecting shaft. The connecting shaft has an opening groove on its side wall to allow the positioning rod to move. The rotating shaft has two coaxial raised edges. The advantages of this invention are: when the head end of the positioning shaft is aligned with the connecting shaft and inserted, the positioning shaft and the connecting shaft can be locked. Disassembly and assembly can be achieved by rotating the rotating shaft. The operation is convenient and simple, and it has good marketability. However, there are shortcomings. When the device is in use, after the positioning rotation, it cannot support the material. This will cause instability during disassembly and assembly. Under pressure, it may fall off.

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.

[0026] The adjusting support assembly 2 includes hinge plates 201. The bottom of the hinge plates 201 is fixedly installed on both sides of the top of the mounting base 101 via limiting bases 202. The top of the hinge plates 201 on both sides is limited and installed at both ends of the supporting top plate 203. At the same time, the end of the pneumatic rod 205 push rod is limited and installed in the middle of the hinge plates 201 on both sides.

Support pulleys 204 are limited and installed on the inner sides of both ends of the supporting top plate 203. The hinge bases 206 on both sides are fixedly installed on the top of the mounting base 101. The adjusting support assembly 2 drives the hinge plates 201 to rotate by the extension and retraction of the pneumatic rods 205, thereby changing the height of the supporting top plate 203. The support pulleys 204 can reduce the friction when the supporting top plate 203 contacts related components. The limiting bases 202 and hinge bases 206 respectively limit and fix the hinge plates 201 and the pneumatic rods 205.

[0027] By installing an adjustable support component 2 in the middle of the device, the material after the angle adjustment is completed can be supported during the assembly and disassembly process, thus ensuring the stability of the processing.

[0028] The bracket assembly 1 includes a mounting base 101, and support side plates 102 are fixedly installed on both sides of the top of the mounting base 101. The mounting base 101 in the bracket assembly 1 provides the mounting foundation for the entire structure, and the support side plates 102 play a role in fixing and supporting the rotating component 3.

[0029] The rotating assembly 3 includes a rotating back plate 301, which is fixedly installed on the inner top of the two side support plates 102. A rotating seat 302 is rotatably installed on the other side of the rotating back plate 301. A rotating mechanism is provided inside the rotating seat 302. Clamping pulleys 303 are installed at the top and bottom of the other side of the rotating seat 302. A clamping groove plate 304 is fixedly installed between the two rotating seats 302. At the same time, a fixed side plate 305 is fixedly installed on the outer wall of one side of the rotating seat 302. The rotating seat 302 rotates around the rotating back plate 301 under the drive of the rotating mechanism, thereby driving the clamping groove plate 304 and the bushing clamped on it to rotate. The clamping pulley 303 can assist the rotation of the bushing. The fixed side plate 305 provides an installation position for the clamping assembly 4.

[0030] Limiting grooves 3041 are provided on the inner walls of both sides of the clamping slot plate 304. The rotating seat 302 in the rotating assembly 3 rotates around the rotating back plate 301 under the drive of the rotating machine, thereby driving the clamping slot plate 304 and the bushing clamped on it to rotate. The clamping pulley 303 can assist the rotation of the bushing. The fixed side plate 305 provides an installation position for the clamping assembly 4.

[0031] The clamping assembly 4 includes a pneumatic push rod 401. One end of the pneumatic push rod 401 is fixedly installed on the inner wall of the fixed side plate 305 through a limiting hinge 402, and the other end of the pneumatic push rod 401 is fixedly installed on the outer wall of the positioning clamping plate 404 through a hinge seat 403. In the clamping assembly 4, the pneumatic push rod 401, through extension and retraction, drives the positioning clamping plate 404 to move under the action of the limiting hinge 402 and the hinge seat 403. The positioning compression push plate 4041 realizes the compression clamping of the bushing. The moving pulley 4042 and the limiting slide rod 4043 slide in the limiting slide groove 3041 to ensure the stability of the movement of the positioning clamping plate 404.

[0032] A positioning clamping plate 4041 is fixedly installed on the bottom side of the end of the positioning clamping plate 404. Movable pulleys 4042 are installed on both sides of the positioning clamping plate 4041. A limiting slide rod 4043 is fixedly installed on the outside of the movable pulley 4042. The limiting slide rod 4043 slides within the limiting slide groove 3041.

[0033] The quick-release structure of this rotating bushing uses bracket assembly 1 as the overall support base, adjustable support assembly 2 to adjust the support height of the bushing, rotating assembly 3 to adjust the angle of the bushing, and clamping assembly 4 to achieve stable clamping and quick disassembly / removal of the bushing. All components work together to complete the disassembly / removal of the rotating bushing. Specifically, the mounting base 101 in bracket assembly 1 provides the mounting base for the entire structure, and the support side plate 102 provides fixation and support for the rotating assembly 3. Adjusting support assembly 2, through the extension and retraction of pneumatic rod 205, drives the hinge support plate 201 to rotate, thereby changing the height of the support top plate 203. Support pulley 204 reduces friction when the support top plate 203 contacts related components. Limiting base 202 and hinge base 206 respectively limit and fix the hinge support plate 201 and pneumatic rod 205. In the rotating assembly 3, the rotating seat 302 rotates around the rotating back plate 301 under the drive of the rotating mechanism, thereby driving the clamping slot plate 304 and the bushing clamped on it to rotate. The clamping pulley 303 can assist the rotation of the bushing. The fixed side plate 305 provides an installation position for the clamping assembly 4. In the clamping assembly 4, the pneumatic push rod 401, through extension and retraction, drives the positioning clamping plate 404 to move under the action of the limiting hinge 402 and the hinge seat 403. The positioning compression push plate 4041 realizes the compression clamping of the bushing. The moving pulley 4042 and the limiting slide rod 4043 slide in the limiting slide groove 3041 to ensure the stability of the movement of the positioning clamping plate 404. In the working process, the device is fixed in a suitable working position by the mounting base 101 to ensure that the supporting side plate 102 in the bracket assembly 1 stably supports the rotating assembly 3. At this time, the adjusting support assembly 2 is in its initial state, the pneumatic rod 205 is not extended or retracted, and the supporting top plate 203 is in a low position; the pneumatic push rod 401 in the clamping assembly 4 is in a retracted state, and the positioning clamping plate 404 is in an open state. The rotating bushing to be disassembled is placed on the clamping slot plate 304. At this time, according to the initial height of the bushing, the extension and retraction of the pneumatic rod 205 in the adjusting support assembly 2 can be controlled to make the hinge support plate 201 rotate, driving the supporting top plate 203 to rise or fall until the supporting pulley 204 on the supporting top plate 203 contacts the bottom of the bushing and provides appropriate support. The limiting base 202 and the hinge base 206 ensure the stability of this adjustment process. The pneumatic push rod 401 in the clamping assembly 4 is activated, the pneumatic push rod 401 extends, and under the action of the limiting hinge 402 and the hinge seat 403, it pushes the positioning clamping plate 404 to move towards the bushing.The positioning and pressing push plate 4041 gradually approaches and presses the bushing, while the moving pulley 4042 drives the limiting slide rod 4043 to slide within the limiting slide groove 3041 of the clamping slot plate 304 until the bushing is stably clamped. According to the disassembly and assembly requirements, the rotating mechanism inside the rotating seat 302 in the rotating assembly 3 is activated, causing the rotating seat 302 to rotate around the rotating back plate 301, thereby driving the clamping slot plate 304 and the clamped bushing to rotate together. The clamping pulley 303 assists in the rotation of the bushing until the bushing is adjusted to a suitable disassembly and assembly angle. After the bushing is at a suitable height and angle, the operator performs the disassembly and assembly operation on the bushing. After the disassembly and assembly are completed, the pneumatic push rod 401 in the clamping assembly 4 is controlled to retract, driving the positioning clamping plate 404 back to the initial position, releasing the clamp on the bushing, and removing the bushing. Next, control the rotating component 3 to reset the rotating seat 302, and then control the pneumatic rod 205 in the adjusting support component 2 to retract, so that the supporting top plate 203 returns to its initial height, and the entire device returns to its initial state, waiting for the next operation.
