Description

Technical Field

[0001] This utility model relates to the technical field of motor components, and in particular to a rotor bearing snap ring mounting machine. Background Technology

[0002] Existing motors have a rotor and a shaft mounted at the center of the rotor and extending to both sides of the rotor. Two circlip grooves are provided on the outer wall of the shaft, and the rotor is positioned between these grooves. To secure the iron core and other components, circlips need to be installed in the circlip grooves. The circlips are non-closed-loop circular sheet structures. Traditionally, the circlips are manually inserted into the circlip grooves. However, manual fixing of the circlips is prone to deformation if the worker applies excessive force, rendering the circlips unusable and requiring replacement, which also reduces work efficiency. Therefore, a circlip installation machine is proposed that automatically installs circlips at both ends of the shaft, as described in application number 2019. The double-spring clipping machine (model 200367856) includes a base, a first movable seat, a second movable seat, a first feeding rod, a second feeding rod, a first pusher, a second pusher, and a power unit. The power unit, the first movable seat, and the second movable seat are all mounted on the base. The first pusher passes through the first movable seat, and the second pusher passes through the second movable seat. The bottom end of the first feeding rod corresponds to the first pusher, and the bottom end of the second feeding rod corresponds to the second pusher. Both the first and second pushers are connected to the power unit. Both the first and second movable seats have grooves, and adjusting rods are provided on the outer sides of both the first and second movable seats. In application, the spring clips are automatically fed, and the pushers quickly push the spring clips to engage them in the spring clip grooves of the rotating shaft.

[0003] In the aforementioned snap ring machine, during snap ring installation, the two ends of the rotating shaft are placed in the grooves of the first movable seat and the second movable seat respectively to achieve fixed installation of the rotating shaft, and the rotor is suspended. However, the inner diameter of the grooves on the first and second movable seats is fixed, while the outer diameter of the rotating shaft is different for different models of motors. This causes the motor shaft to not be tightly fitted with the groove. When the snap ring is pressed into the snap ring groove of the rotating shaft, the pusher will push the rotating shaft because the rotating shaft cannot be fixed, thus preventing the snap ring from being tightly clamped into the snap ring groove.

[0004] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Summary of the Invention

[0005] The purpose of this utility model is to provide a rotor bearing snap ring installation machine to solve the problem that snap ring machines cannot effectively fix the motor shaft, which easily causes the shaft to move and makes it difficult for the snap ring to be inserted into the snap ring groove.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] A rotor bearing snap ring installation machine includes a base, an installation device mounted on the base for fixing snap ring mounting components, an output device for sequentially outputting several snap rings, and an insertion device for inserting one snap ring from the output device into a rotating shaft. Two output devices are provided, arranged laterally opposite each other. The two output devices are divided into a first output device and a second output device. The first output device is fixedly mounted on the base, and the second output device is slidably mounted on the base in a manner that allows it to translate towards the first output device. The base has a lifting block located above the output ends of the two output devices, capable of vertical movement. The bottom surface of the lifting block has an upward-facing recessed receiving groove that matches the output end of the output device. One end of the receiving groove facing the output device extends outward from the lifting block. The lifting block has a through hole on the side facing the mounting device that communicates with the receiving groove and leads to the bottom of the lifting block. The inner wall of the receiving groove at the end facing away from the output device has an embedding notch for a single snap ring to be embedded and fall downward. The mounting device is located between the output ends of the two output devices. The top surface of the mounting device has a receiving through groove that accompanies the rotor of the motor laterally. The through direction of the receiving through groove is the same as the lateral arrangement direction of the first and second output devices. The base is provided with a clamping rod corresponding to the outside of the two lifting blocks. The rod can extend into the receiving groove and is located below the output end of the output device and opposite to the motor shaft on the receiving through groove. The two clamping rods are mounted on the base in a way that allows them to move towards or away from each other and can be adjusted up and down.

[0008] With the direction of the two output devices facing each other as the left and right directions, the base has an upper plate. The first output device is fixedly installed on the left end of the top surface of the upper plate via a left fixed platform. The second output device is installed on the right end of the top surface of the upper plate via a right sliding platform, which allows it to move left and right. Both the first and second output devices have a feeding rod for stacking several snap rings on top and allowing them to fall down one by one in sequence. Both feeding rods are inclined downward and arranged opposite each other left and right. The mounting device has a mounting base, which is located on the right side of the top surface of the upper plate and is adjustable left and right. The mounting base is located between the left fixed platform and the right sliding platform.

[0009] The upper plate has two slide rails extending in the left-right direction and spaced apart in the front-back direction on the top right end. The right sliding platform and the mounting base slide on the two slide rails through sliding blocks. The left fixed platform is installed on the left side of the two slide rails, and the mounting base is detachably connected to the left fixed platform. The upper plate has a sliding drive device between the two slide rails to drive the right sliding platform to slide left and right on the right side of the mounting base.

[0010] The mounting plate has a vertical block on its top surface. The top surface of the vertical block is an inclined surface that slopes downwards. The two inclined surfaces form a flared structure that gradually narrows from top to bottom. The feeding rod is an inclined strip-shaped rod, with its upper end inclined and mounted on the corresponding inclined surface. The lower end of the feeding rod has a concave arc structure that slopes downwards. A retaining strip protrudes from the middle of the side of the feeding rod facing away from the inclined surface, allowing a retaining spring to be engaged. The extension direction of the retaining strip is consistent with the extension direction of the feeding rod. A downward extending rod protrudes from the lower end of the feeding rod, facing away from the vertical block, and extends horizontally into the receiving groove in the left-right direction. The end face of the locking bar facing away from the vertical block has an upper extension rod protruding above the lower extension rod and connected to the locking bar in an arc transition. The ends of the upper and lower extension rods facing away from the vertical block extend into the receiving groove and face the insertion notch. The mounting plate is provided with a lifting and moving device that drives the lifting block to move up and down and to extend the upper and lower extension rods into the receiving groove. The side of the locking bar and the upper extension rod facing away from the feeding rod has a locking strip protruding from the front and rear sides of the locking bar and the upper extension rod and into which the snap ring is locked. The feeding rod is provided with a pressure block that can be embedded in the locking bar and the locking strip and move downward with the output of the snap ring.

[0011] Vertical plates are erected on the top surface of the mounting plate on both the front and rear sides of the vertical block. The vertical plates are located within the lower end range of the feeding rod. A connecting plate is connected between the two vertical plates on the side facing away from the mounting device, which is suspended above the feeding rod. An upper connecting plate is connected to the top surface of the connecting plate and the two vertical plates. The lifting and moving device has a lifting cylinder, which is erected on the top surface of the upper connecting plate. The output end of the lifting cylinder extends downward beyond the upper connecting plate, and a disassembly block is erected on the output end of the lifting cylinder. The disassembly block is slidably mounted on the connecting plate, and the lower end of the disassembly block is disassembled and installed together with the lifting block.

[0012] The lifting block has an integrally formed first block, second block, and receiving block. The first block and the second block both extend in the left-right direction and are spaced apart in the front-back direction. The ends of the first block and the second block facing the mounting base are connected by the receiving block. The hollow space formed by the first block, the second block, and the receiving block is the receiving groove. The side of the receiving block facing away from the mounting base is recessed with the aforementioned embedding notch for accommodating a single retaining spring and extending to the outside of the bottom surface of the receiving block. The bottom of the embedding notch is recessed with the aforementioned rotating shaft through hole extending to the outside of the bottom surface of the receiving block and for the rotating shaft to extend into. The top surfaces of the first block and the second block are detachably connected to the disassembly block.

[0013] The first block and the second block have an insert block protruding on the top surface of the end facing away from the receiving block. The insert block has a locking block protruding on the upper end of the side facing the receiving block. The disassembly block has an insert groove recessed on the side facing away from the mounting base, which extends to the bottom surface of the disassembly block and allows the insert block to be inserted into it. The bottom of the insert groove has a locking groove recessed at the position of the locking block, which allows the locking block to be locked in.

[0014] The tightening rod is a screw rod. A screw block is erected on the side of the mounting plate facing away from the mounting base and is screwed together with the screw rod. The screw block is locked on the mounting plate in a way that can be adjusted up and down. The screw rod extends in the left and right direction and passes through the screw block and the vertical block in sequence to the receiving groove. A nut that is screwed onto the screw rod between the screw block and the vertical block is screwed in to engage with the screw rod.

[0015] The mounting base has a fixing plate and a storage block. The fixing plate extends in the front-back direction and is located on the left end of the top surface of the two slide rails via the aforementioned sliding block. The storage block is located on the middle of the top surface of the fixing plate and has a storage groove that extends in the left-right direction. This storage groove is the aforementioned through-slot for receiving. The top surfaces of the two mounting plates and the fixing plate are on the same plane, and the front end of the top surface of the fixing plate is locked together with the mounting plate on the left fixing platform and can be adjusted left and right for installation.

[0016] In this novel rotor bearing snap ring installation machine, several snap rings are arranged sequentially on two output devices, and the rotor is placed in the receiving through groove. The height of the clamping rods in the vertical direction is adjusted so that the two clamping rods are respectively positioned opposite the end faces of the two rotating shafts. The second output device moves towards the installation device, and the two clamping rods move relative to each other and clamp onto the left and right end faces of the rotating shaft, so that the rotor is relatively fixed in the receiving through groove. At the same time, the two embedded notches are respectively positioned directly above the snap ring grooves. The two lifting blocks are driven to move downward. At this time, the end of the clamping rod facing the installation device enters the receiving groove, and the end of the rotating shaft facing the clamping rod enters the rotating shaft through hole. The snap rings embedded in the notches are then snapped into the snap ring grooves of the rotating shaft under the downward pressure of the lifting blocks. Compared with existing technologies, the accommodating through slot can accommodate rotors of different models, while the clamping rod can clamp the two ends of the rotating shaft, thereby effectively fixing the rotating shaft when the snap ring is inserted into the snap ring slot, making the rotating shaft less prone to movement and facilitating the snap ring to be clamped into the snap ring slot; moreover, the two lifting blocks simultaneously insert the two snap rings into the snap ring slot from top to bottom, which also makes it less likely for the rotor to shift within the accommodating through slot.

[0022] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0023] A rotor bearing snap ring mounting machine, such as Figures 1-5 As shown, the device includes a base, a mounting device for fixing the snap ring mounting component on the base, an output device for sequentially outputting several snap rings, and a snapping device for snapping one of the snap rings from the output device into the snap ring groove of the rotating shaft. Two output devices are provided, arranged laterally and spaced apart. In application, the snap ring mounting component (i.e., the rotor) is placed on the mounting device, the rotating shaft extends in the left-right direction, several snap rings are arranged sequentially on the output device, and the snapping device snaps one of the snap rings from the output device into the snap ring groove of the rotating shaft.

[0024] The output device is divided into a first output device and a second output device. The first output device is fixedly mounted on the base, and the second output device is slidably mounted on the base in a manner that allows it to translate towards the first output device. Specifically, the base has an upper plate 1. The first output device is fixedly mounted on the left end of the top surface of the upper plate 1 via a left fixed platform 11, and the second output device is mounted on the right end of the top surface of the upper plate 1 via a right sliding platform 12 in a manner that allows it to translate left and right. That is, the right end of the top surface of the upper plate 1 is provided with two slide rails 13 that extend in the left and right directions and are spaced apart in the front and back directions. Both the left fixed platform 11 and the right sliding platform 12 have mounting plates. The first output device and the second output device are respectively mounted on the two mounting plates. The bottom surface of the mounting plate of the right sliding platform 12 slides on the two mounting plates via a first sliding block 131. On the right end of slide rail 13, the mounting device is positioned between two mounting plates. The mounting device slides on the top left surface of the two slide rails via a second sliding block 132. The left fixed platform 11 is fixedly mounted on the left side of the two slide rails 13, meaning the mounting plate of the left fixed platform 11 is suspended above the left end of the top surface of the upper plate 1. The bottom surface of the mounting plate of the left fixed platform 11 is connected to the top surface of the upper plate 1 via a vertical connecting plate 14, and the top surfaces of the two mounting plates are on the same plane. A sliding drive device is provided on the upper plate 1 between the two slide rails 13 to drive the right sliding platform 12 to slide left and right on the right side of the mounting device. Specifically, the sliding drive device has a sliding cylinder 14 mounted on the top surface of the upper plate 1. The sliding cylinder extends in the left-right direction, with its output end facing left, and the output end of the sliding cylinder 14 is connected to the bottom surface of the mounting plate of the right sliding platform 12. In application, driving the sliding cylinder 14 moves the second output device to the left, resetting the sliding cylinder, and then moving the second output device to the right.

[0025] Both the first and second output devices have a feeding rod 2 for stacking several retaining rings and allowing them to fall sequentially. Both feeding rods 2 are inclined downwards and positioned opposite each other. The feeding rod 2 of the first output device is mounted on the mounting plate of the left fixed platform 11, and the feeding rod 2 of the second output device is mounted on the mounting plate of the right sliding platform 12. Specifically, the top surface of the mounting plate has a vertical block 3, the top surface of which is an inclined surface 31 oriented downwards. The two inclined surfaces 31 form a flared structure that gradually narrows from top to bottom. The feeding rod 2 is an inclined strip-shaped rod, and its upper end is inclined and mounted on the corresponding inclined surface 31, i.e., the upper ends of the two feeding rods 2 form a flared structure that gradually narrows from top to bottom. The structure includes a connecting locking plate 311 connecting the inclined surface 31 and the upper end of the feeding rod 2. The feeding rod 2 is locked in the middle position of the connecting locking plate 311. A first screw hole is recessed on the side of the feeding rod 2 facing the connecting locking plate 311. A second screw hole is recessed on the side of the connecting locking plate 311 facing the inclined surface, corresponding to the position of the first screw hole. The connecting locking plate is locked together with the feeding rod 2 by bolts passing through the first and second screw holes. The inner wall of the second screw hole is recessed with a groove that leads to the outside of the connecting locking plate 311 and accommodates the head of the bolt. Two sets of first locking holes 100 are recessed on the side of the connecting locking plate 311 facing away from the inclined surface 31. The feeding rod 2 is locked to the two sets of first locking holes 100. Between the first locking holes 100, the inclined surface 31 is recessed with a second locking hole corresponding to the position of the first locking hole 100. The connecting locking plate 311 is locked together with the vertical block 3 by connecting bolts passing through the first locking hole 100 and the second locking hole in sequence. The lower end of the feeding rod 2 has a downward concave arc structure. The middle position of the side of the feeding rod 2 facing away from the inclined surface 31 is provided with a retaining strip 21 for the retaining spring to be inserted. The extension direction of the retaining strip 21 is consistent with the extension direction of the feeding rod 2, that is, the upper end of the retaining strip 21 is inclined, and the lower end of the retaining strip 21 has a downward concave arc structure. The lower end of the feeding rod 2, facing away from the vertical block 3, is provided with a downward extension rod 22 that is horizontally set in the left-right direction and extends out of the mounting plate. One end of strip 21 facing away from the vertical block 3 has an upper extension rod 211 protruding above the lower extension rod 22 and connected to the strip 21 in an arc transition. The strip 21 and the upper extension rod 211 have a snap-in strip 212 protruding from the front and rear sides of the strip 2 and the upper extension rod 211 and for snap-in springs to be snapped into. The feed rod 2 has a pressure block that can be embedded in the strip 21 and the snap-in strip 212 and move downwards with the output of the snap-in spring. That is, the pressure block 22 has a block structure. The side of the pressure block facing the inclined surface 31 has an embedding groove for the strip 21 and the snap-in strip 211 to be embedded in. The working principle of the feed rod stacking several snap-in springs on top and outputting the snap-in spring at the end is a well-known technology and will not be described in detail here.In application, several snap rings are snapped onto the snap bar 21 and the snap bar 212. The snap ring at the very end is pressed down by the pressure block and falls outside the feed bar 2.

[0026] The base is located above the output ends of the two output devices and is equipped with a lifting block 4 that can move up and down. Specifically, the mounting plate is equipped with a lifting and moving device that drives the lifting block 4 to move up and down. That is, vertical plates 5 are erected on both the front and rear sides of the vertical block 3 on the top surface of the mounting plate. The vertical plates 5 are located within the lower end range of the feeding rod 2. A connecting plate 51 suspended above the feeding rod 2 is connected between the two vertical plates 5 on the side facing the mounting device. A connecting plate 52 is connected between the connecting plate 51 and the top surface of the two vertical plates 5. The lifting and moving device has lifting... A lowering cylinder 521 is vertically mounted on the top surface of the connecting plate 52. The output end of the lifting cylinder 521 extends downward beyond the connecting plate 52, and a disassembly block 511 is vertically mounted on the output end of the lifting cylinder 521. The disassembly block 511 is slidably mounted on the connecting plate 51, that is, a slide bar extending vertically is vertically mounted on the side of the connecting plate 51 facing the disassembly block 511. A slider that slides on the slide bar is connected to the side of the disassembly block 511 facing the connecting plate 51. The lower end of the disassembly block 511 is detachably and detachably mounted to the lifting block 4. In application, the lifting cylinder is activated, driving the lifting block 4 to move downward. When the lifting cylinder is reset, the lifting block 4 moves downward.

[0027] The bottom surface of the lifting block 4 is recessed upwards with a receiving groove 200 that matches the output end of the output device. The end of the receiving groove 200 facing the output device extends to the outside of the lifting block 4. The side of the lifting block 4 facing the mounting device has a rotating shaft through hole 300 that communicates with the receiving groove 200 and extends to the bottom surface of the lifting block 4. The inner wall of the receiving groove 200 facing away from the output device has a recessed notch for a single snap ring to be embedded and fall downwards. Specifically, the lifting block 4 has an integrally formed first block 41, second block 42, and receiving block 43. The first block 41 and second block 42 both extend in the left-right direction and are spaced apart in the front-back direction. One end of block 42 facing the mounting device is connected to receiving block 43. The hollow space formed by the first block 41, the second block 42 and the receiving block 43 is the receiving groove 200. The receiving block has a flared structure that tapers towards the mounting device. The side of receiving block 43 facing away from the mounting device is recessed with the aforementioned embedding notch for a single retaining spring to be received and leading to the bottom surface of receiving block 43. The ends of the upper extension rod 211 and the lower extension rod 22 facing away from the vertical block extend into the receiving groove 200 and face the embedding notch. The bottom of the embedding notch is recessed with the aforementioned rotating shaft through hole 300 that leads to the bottom surface of receiving block 43 and allows the rotating shaft to be inserted. The top surfaces of the first block 41 and the second block 42 are locked together with the disassembly block 511. In application, a retaining ring located at the ends of the upper extension rod 211 and the lower extension rod 22 moves out of the upper extension rod 211 and the lower extension rod 22 under the pressure of the pressing block and falls into the embedding notch. At this time, the retaining ring groove of the rotating shaft is positioned directly below the embedding notch. The lifting cylinder 521 is activated, which drives the lifting block 4 to move down, pressing the retaining ring in the embedding notch into the retaining ring groove. When the retaining ring is pressed into the retaining ring groove, the rotating shaft enters the receiving groove 200.

[0028] The mounting device is located between the output ends of the two output devices. The top surface of the mounting device has a transverse through-groove 400 that accommodates the rotor of the power supply motor. The through-groove 400's direction is the same as the transverse arrangement direction of the first and second output devices. Specifically, the mounting device has a mounting base 6, which is positioned on the right side of the top surface of the upper plate 1, allowing for left-right adjustment. The mounting base 6 is located between the left fixed platform 11 and the right sliding platform 12, and is detachably connected to the left fixed platform 11. That is, the mounting base 6 has a fixing plate 61 and a placement block 62. The fixing plate 61 extends in the front-back direction and is positioned on the left end of the top surface of the two slide rails 13 via a second sliding block 132. The placement block 62... The top surface of the fixed plate 61 is locked to the center. The top surface of the storage block 62 is recessed with a storage groove that runs through the left and right directions. This storage groove is the aforementioned through-groove 400. The top surfaces of the two mounting plates and the fixed plate 61 are on the same plane. The front end of the top surface of the fixed plate 61 is locked with a locking plate 611 that is locked together with the mounting plate on the left fixed platform 11 and can be adjusted left and right. That is, the front end of the top surface of the fixed plate 61 is recessed with several adjustment holes spaced apart in the left and right directions. The locking plate 611 is recessed with a strip hole that runs vertically through the adjustment holes and extends in the left and right directions. Each adjustment hole falls within the range of the strip hole. The locking plate 611 is locked together with the fixed plate 61 by adjusting bolts passing through the strip hole and one of the adjustment holes in sequence. In application, the rotor is placed in the storage groove, with both ends of the shaft suspended outside the storage groove. The retaining spring groove on the left shaft is aligned with the notch below the left lifting block. Then, the locking plate is locked to fix the mounting base. Since the relative positions of the snap ring groove and the insert notch of different sized shafts are not necessarily the same, the mounting base can be adjusted left and right relative to the insert notch to adapt to situations where the snap ring groove positions of different shafts are different.

[0029] The base is provided with a clamping rod 7 corresponding to the two lifting blocks 4, which can extend into the receiving groove 200 and are located below the output end of the output device, opposite to the rotating shaft of the motor on the receiving through groove 400. The two clamping rods 7 are installed on the base in a way that can move towards or away from each other and can be adjusted up and down. Specifically, the clamping rod 7 is a screw rod. The mounting plate is located on the side of the vertical block 3 facing away from the mounting device and has a screw block 32 that is screwed together with the screw rod. The screw block 32 is arranged opposite to the vertical block 3 at intervals, and the screw block 32 is locked to the mounting plate in a way that can be adjusted up and down. That is, the screw block 32 has a number of screw holes 500 arranged at intervals in the vertical direction. The side of the mounting plate facing the screw block 32 is recessed at the position of the screw holes 500. The screw-fitting fixing hole is used to lock the screw-fitting block 32 to the mounting plate by passing through a screw-fitting opening 500 and a screw-fitting fixing hole in sequence with locking bolts. The screw-fitting rod extends in the left and right direction and passes through the screw-fitting block and the vertical block in sequence to the receiving groove. A nut that screws into the screw-fitting rod is screwed between the screw-fitting block and the vertical block 3. That is, the screw-fitting block has a screw-fitting hole that passes through in the left and right direction and allows the screw-fitting rod to extend out. The screw-fitting hole is above the screw-fitting opening 500. The inner side wall of the screw-fitting hole has internal threads, and the outer side wall of the screw-fitting rod has external threads. The vertical block has a strip-shaped through hole that passes through in the left and right direction and extends in the up and down direction. The screw-fitting rod passes through the strip-shaped through hole and is screwed into the inner side wall of the strip-shaped through hole. A handwheel that drives the screw-fitting rod to rotate is connected to the end of the screw-fitting rod facing away from the vertical block 3. In application, place the rotor in the accommodating through slot 400, with the shaft extending in the left and right direction. Position the two clamping rods opposite the two end faces of the shaft, align the clamping rods vertically, and position the two clamping rods opposite the two end faces of the shaft horizontally. Lock the screw block, turn the handwheel, and the screw rods will rotate on the screw block, causing the screw rods to move horizontally until they are clamped against the end face of the shaft. The two screw rods are clamped against the two end faces of the shaft, and the nuts are clamped against the screw block, thus achieving the clamping of the motor shaft.

[0030] In this novel rotor bearing snap ring installation machine, several snap rings are arranged sequentially on two feeding rods, and the rotor is placed in the receiving through groove 400. The height of the clamping rods in the vertical direction is adjusted so that the two clamping rods and the two end faces of the two rotating shafts are respectively positioned opposite each other. The second output device moves towards the installation device, and the two clamping rods move relative to each other and clamp onto the left and right end faces of the rotating shaft, so that the rotor is relatively fixed in the receiving through groove. At the same time, the two embedded notches are respectively positioned directly above the two snap ring grooves. The lifting cylinder is started, and the two lifting blocks 4 move downward. At this time, the end of the clamping rod facing the mounting seat enters the receiving groove, and the end of the rotating shaft facing the clamping rod enters the rotating shaft through hole. The snap rings embedded in the notches are then engaged in the snap ring grooves of the rotating shaft. Compared with existing technologies, the accommodating through slot can accommodate rotors of different models, while the clamping rod can clamp the two ends of the rotating shaft, thereby effectively fixing the rotating shaft when the snap ring is inserted into the snap ring slot, making the rotating shaft less prone to movement and facilitating the snap ring to be clamped into the snap ring slot; moreover, the two lifting blocks simultaneously insert the two snap rings into the snap ring slot from top to bottom, which also makes it less likely for the rotor to shift within the accommodating through slot.

[0031] The top surface of the first block 41 and the second block 42, facing away from the receiving block 43, has a protruding insert block 411. The upper end of the insert block 411 facing the receiving block 43 has a protruding locking block 4111. The disassembly block 511, facing away from the mounting base 6, has a recessed insert groove extending to the bottom surface of the disassembly block 511 and into which the insert block 411 is fitted. The bottom of the insert groove, corresponding to the position of the locking block 4111, has a recessed locking slot for the locking block 4111 to be secured within. In application, the lifting block and the lifting moving device can be disassembled and installed, allowing replacement of receiving grooves 200, rotating shaft through holes 300, and lifting blocks with different sizes of insert slots, and adapting to situations requiring different sizes of retaining rings to be inserted into retaining ring slots.

[0032] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
