[0002] Marine gearboxes are the core transmission components of marine propulsion systems. The internal gear ring, as a key part for transmitting large torques, is characterized by its large size, thin wall thickness, and high tooth surface precision requirements.

[0003] In terms of clamping and positioning of internal gear rings, marine internal gear rings are large in size and weight (with diameters reaching several meters), making clamping operations very difficult. Traditional clamping methods usually involve pressing the internal gear ring from the end face with pressure plates and fixing it through the T-slots on the worktable. This clamping method requires multiple pressure plates to be arranged around the workpiece, and the clamping and alignment process is time-consuming. Furthermore, for large internal gear rings, there are significant safety hazards when operators install pressure plates around the workpiece. Summary of the Invention

[0020] The beneficial effects of this invention are:
[0021] 1. Utilizing a fixed plate, a movable plate, a load-bearing plate, a third electric push rod, a first electric push rod, a T-slot, a machine base, and a T-block, the T-block is driven by the third electric push rod during the loading of the internal gear ring body. This causes the T-block to slide within the T-slot, which in turn causes the movable plate to slide laterally under the drive of the third electric push rod. This, in turn, causes the movable plate to move synchronously with the first electric push rod inside it. This, in turn, assists the lifting plate in moving within the worktable via the storage rod, enabling rapid loading and unloading. This also helps to prevent the internal gear ring from being obstructed by the support rod due to its large size.

During the rising process, the auxiliary pressing plate is pressed, and the return spring is stretched simultaneously. After the lifting plate descends, the auxiliary pressing plate can quickly return to its original position. When the auxiliary pressing plate is being pressed, it can quickly drive the connecting block to drive the internal structure of the boring drive assembly.
[0023] 3. Utilizing the second electric push rod, placement tube, adjusting motor, fixed rod, moving block, tilting support rod, clamping block, machining tool, coordinating moving block, and placement block, the second electric push rod quickly drives the adjusting motor to move downwards. The distance between the machining tool and the internal gear ring body is quickly adjusted by the second electric push rod, thereby improving the machining effect of the equipment to a certain extent. At the same time, during the machining process, the coolant inside the water tank is quickly discharged through the placement tube, which provides rapid auxiliary cooling for the machining tool during the machining process. Meanwhile, a miniature telescopic rod is installed inside the fixed rod, which can adapt to the machining radius of the internal gear ring body as needed.
[0024] 4. Utilizing a support frame, a micro drive motor, a collection frame, a rubber drive wheel, a T-shaped connecting rod, a T-shaped connecting block, an n-shaped frame, a fourth electric push rod, a spring plate, a push rod, a mounting block, and a moving groove, the internal structure of the lifting and transmission assembly drives the mounting block upwards, simultaneously compressing the spring plate to increase its bending degree. This, in turn, rapidly moves the support frame closer to the internal gear ring body via the push rod, allowing the micro drive motor to quickly rotate the rubber drive wheel. Consequently, the internal gear ring rotates rapidly under the drive of the rubber drive wheel, thus improving the boring effect of the equipment to a certain extent. Attached Figure Description

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.
[0038] Example 1:
[0039] Reference Figure 1 - Figure 7 According to one embodiment of the present invention, a boring device for internal gear rings of marine gearboxes is provided, including a main body assembly 100, a lifting and transmission assembly 200 and a boring drive assembly 300.
[0040] The main component 100 includes a workbench 101 and a protective frame 102 fixedly connected to the upper surface of the workbench 101. A door 103 is fixedly connected to one side of the protective frame 102 via a hinge 104.
[0041] Furthermore, the lifting and transmission assembly 200 includes a support rod 204 fixedly connected to the lower surface of the workbench 101 and a load-bearing plate 203 fixedly connected to the lower surface of the support rod 204. A fixed plate 201 is fixedly connected to one side of the load-bearing plate 203, and a first electric push rod 206 is fixedly connected inside the load-bearing plate 203.
[0042] Finally, the boring drive assembly 300 includes a second electric push rod 303 fixedly connected to the protective frame 102 and a storage frame 305 fixedly connected to the upper surface of the worktable 101. One end of the telescopic shaft of the second electric push rod 303 is fixedly connected to an adjusting motor 306, and one end of the output shaft of the adjusting motor 306 is fixedly connected to a fixing rod 307.
[0043] Furthermore, a T-slot 207 is formed on one side of the load-bearing plate 203, and a T-block 209 is slidably connected within the T-slot 207. A movable plate 202 is fixedly connected to one side of the T-block 209, and the outer surface of the first electric push rod 206 is fixedly connected within the movable plate 202. The T-slot 207, formed on one side of the load-bearing plate 203, provides precise sliding guidance for the T-block 209, restricting its reciprocating movement only along the direction of the T-slot 207. The T-block 209 is slidably connected within the T-slot 207, and its lateral protrusion is perpendicular to the T-slot 207. The groove fits to prevent the T-block 209 from coming out of the T-slot 207 during sliding; the movable plate 202 is fixed to one side of the T-block 209 and moves synchronously with the T-block 209, transmitting the sliding of the T-block 209 to the first electric push rod 206; the first electric push rod 206 is fixed inside the movable plate 202 and can move horizontally with the movable plate 202, realizing the horizontal position adjustment of the first electric push rod 206, thereby adapting to the feeding requirements of internal gear ring bodies 105 of different sizes and avoiding obstruction by the support rod 204 during placement.
[0044] Furthermore, a third electric push rod 205 is fixedly connected to one side of the load-bearing plate 203, and a base 208 is fixedly connected to one side of the load-bearing plate 203. The outer surface of the third electric push rod 205 is fixedly connected to the upper surface of the base 208, and one end of the third electric push rod 205 is fixedly connected to one side of the T-shaped block 209. The third electric push rod 205, fixed to one side of the load-bearing plate 203, extends in the same direction as the extension of the T-shaped groove 207, serving as the driving source for the horizontal movement of the moving plate 202. The base 208, fixed to one side of the load-bearing plate 203, provides a stable support for the third electric push rod 205. A support is installed to ensure the stability of the third electric push rod 205 during the extension and retraction process. One end of the extension shaft of the third electric push rod 205 is fixedly connected to the T-shaped block 209. When the third electric push rod 205 extends or retracts, it directly drives the T-shaped block 209 to slide along the T-shaped groove 207, thereby driving the moving plate 202 and the first electric push rod 206 to move horizontally. This enables the lifting plate 210 and the bearing plate 215 to be adjusted laterally at the feeding position, allowing them to extend outward at the auxiliary moving groove 301. This facilitates the placement of the large internal gear ring body and avoids interference during placement due to the obstruction of the support rod 204.
[0045] Furthermore, a lifting plate 210 is fixedly connected to one end of the first electric push rod 206, a bearing plate 215 is fixedly connected to one side of the lifting plate 210, and a storage rod 214 is fixedly connected to one side of the lifting plate 210. A return spring 211 is fixedly connected inside the worktable 101, an auxiliary pressing plate 212 is fixedly connected to the upper surface of the return spring 211, and a connecting block 213 is fixedly connected to one side of the auxiliary pressing plate 212. The first electric push rod 206 is fixedly connected to the lifting plate 210 via its telescopic shaft, driving the lifting plate 210 to rise and fall vertically. The bearing plate 215 is fixed to one side of the lifting plate 210 and rises and falls synchronously with the lifting plate 210, used to support the internal gear ring body 105 from below. The storage rod 214 is fixed to one side of the lifting plate 210 and together with the bearing plate 215 constitutes the internal gear ring body. The bearing platform of 105 provides multi-point support to distribute the weight of the internal gear ring body 105; the return spring 211 is fixed inside the worktable 101, and its upper end is fixedly connected to the auxiliary pressing plate 212, applying a downward elastic force to the auxiliary pressing plate 212; the auxiliary pressing plate 212 moves upward due to the compression of the lifting plate 210 during the lifting process of the lifting plate 210, stretching the return spring 211; when the lifting plate 210 descends, the return spring 211 releases elastic potential energy to pull the auxiliary pressing plate 212 back to its original position; the connecting block 213 is fixed to one side of the auxiliary pressing plate 212 and rises and falls synchronously with the auxiliary pressing plate 212. When the auxiliary pressing plate 212 is compressed, it transmits the lifting motion to the subsequent spring plate 322, realizing the linkage drive of the internal structure of the boring drive assembly 300.
[0046] Working principle:
[0047] By utilizing a fixed plate, a movable plate, a load-bearing plate, a third electric push rod, a first electric push rod, a T-slot, a machine base, and a T-block, the T-block is driven by the third electric push rod during the loading of the internal gear ring body. This causes the T-block to slide within the T-slot, and the movable plate slides laterally under the drive of the third electric push rod. This causes the movable plate to move synchronously with the first electric push rod inside it. The lifting plate moves within the worktable with the assistance of the storage rod, enabling rapid loading and unloading. This also helps to prevent the internal gear ring from being obstructed by the support rod due to its large size.
[0048] The lifting plate, return spring, auxiliary pressing plate, connecting block, storage rod, and bearing plate are used to support the internal gear ring body. This allows the ring to rise quickly under the drive of the first electric push rod. During the rise, the ring presses the auxiliary pressing plate and simultaneously stretches the return spring. After the lifting plate descends, the auxiliary pressing plate can quickly return to its original position. When the auxiliary pressing plate is being pressed, it can quickly drive the connecting block to drive the internal structure of the boring drive assembly.
[0049] The system utilizes a second electric push rod, a placement tube, an adjusting motor, a fixed rod, a moving block, an inclined support rod, a clamping block, a machining tool, a coordinating moving block, and a placement block. The second electric push rod quickly drives the adjusting motor to move downwards, thereby rapidly adjusting the distance between the machining tool and the internal gear ring body, thus improving the machining effect of the equipment to a certain extent. At the same time, during the machining process, the placement tube quickly discharges the coolant from the water tank, providing rapid auxiliary cooling for the machining tool. Additionally, the fixed rod is equipped with a miniature telescopic rod, which can adapt to the machining radius of the internal gear ring body as needed.
[0050] Utilizing a support frame, a micro drive motor, a collection frame, a rubber drive wheel, a T-shaped connecting rod, a T-shaped connecting block, an n-shaped frame, a fourth electric push rod, a spring plate, a push rod, a mounting block, and a moving groove, the internal structure of the lifting and transmission assembly drives the mounting block upwards, simultaneously squeezing the spring plate to increase its bending degree. This, in turn, causes the push rod to quickly move the support frame closer to the internal gear ring body, allowing the micro drive motor to drive the rubber drive wheel to rotate rapidly. Consequently, the internal gear ring rotates rapidly under the drive of the rubber drive wheel, thus improving the boring effect of the equipment to a certain extent.
[0051] Example 2:
[0052] Reference Figure 3 - Figure 7 The difference from Embodiment 1 is that: a sliding groove is provided on the lower surface of the workbench 101, and a T-shaped connecting block 319 is slidably connected in the sliding groove. A fourth electric push rod 321 is fixedly connected in the workbench 101, and the outer surface of the fourth electric push rod 321 is slidably connected in the T-shaped connecting block 319. An n-shaped frame 320 is fixedly connected to one side of the T-shaped connecting block 319. The sliding groove is provided on the lower surface of the workbench 101 to provide horizontal sliding guidance for the T-shaped connecting block 319. The T-shaped connecting block 319 is slidably connected in the sliding groove, and its T-shaped structure cooperates with the sliding groove to prevent the T-shaped connecting block 319 from coming out of the sliding groove. The fourth electric push rod 321 is fixed in the workbench 101, and one end of it is fixedly connected to the n-shaped frame 320. By extending and retracting, the n-shaped frame 320 and the T-shaped connecting block 319 are moved horizontally along the sliding groove, thereby adjusting the horizontal position of the collection frame 316.
[0053] Furthermore, one end of the fourth electric push rod 321 is fixedly connected to one side of the n-shaped frame 320. T-shaped connecting rods 318 are symmetrically distributed at equal intervals on the lower surfaces of the support plate 215 and the storage rod 214. A collection frame 316 is fixedly connected to the lower surface of the T-shaped connecting block 319, and a moving groove 325 is provided inside the collection frame 316. The fourth electric push rod 321 is fixedly connected to the n-shaped frame 320 via its telescopic shaft, causing the n-shaped frame 320 to drive the T-shaped connecting block 319 and the collection frame 316 to move horizontally synchronously. T-shaped connecting rods 318 are symmetrically fixed at equal intervals on the lower surfaces of the support plate 215 and the storage rod 214. The outer surface of 318 slides in contact with the moving groove 325 inside the collection frame 316. When the support plate 215 and the storage rod 214 are raised or lowered, the fourth electric push rod 321 pushes the collection frame 316 toward the worktable 101, so that the moving groove 325 and the T-shaped connecting rod 318 are released from their engagement. This allows the T-shaped connecting rod 318 to move up and down under the action of the support plate 215 and the storage rod 214, and avoids interference between the movement direction of the support plate 215 and the storage rod 214 and the collection frame 316. The collection frame 316 is fixed to the lower surface of the T-shaped connecting block 319 and is used to collect the chips generated by boring and prevent the chips from scattering.
[0054] Furthermore, the outer surface of the T-shaped connecting rod 318 is slidably connected to the inner surface of the moving groove 325. An mounting block 324 is fixedly connected to the upper surface of the connecting block 213, and a spring sheet 322 is fixedly connected to the upper surface of the mounting block 324. A push rod 323 is fixedly connected to one side of the spring sheet 322, and a support frame 314 is fixedly connected to the end of the push rod 323 away from the spring sheet 322. The T-shaped connecting rod 318 slides within the moving groove 325, providing auxiliary support for the collecting frame 316 during processing. The mounting block 324 is fixed to the upper surface of the connecting block 213 and rises and falls with the connecting block 213, providing support for the spring sheet 322. The spring plate 322 is fixed at one end to the upper surface of the mounting block 324 and at the other end to the push rod 323. When the mounting block 324 rises, the spring plate 322 is compressed and undergoes elastic deformation, storing elastic potential energy. One end of the push rod 323 is fixedly connected to the spring plate 322 and at the other end is fixedly connected to the support frame 314, transmitting the elastic force of the spring plate 322 to the support frame 314, causing the support frame 314 to move toward the inner gear ring body 105. The support frame 314 is used to mount the rubber drive wheel 317, which, under the push of the spring plate 322, contacts the outer surface of the inner gear ring body 105.
[0055] Furthermore, a rubber drive wheel 317 is rotatably connected inside the support frame 314, and a micro drive motor 315 is fixedly connected to the upper surface of the support frame 314. One end of the output shaft of the micro drive motor 315 is fixedly connected to one end of the rubber drive wheel 317. A moving block 308 is slidably connected inside the fixed rod 307, and an inclined support rod 309 is fixedly connected to the lower surface of the moving block 308. The rubber drive wheel 317 is rotatably connected inside the support frame 314, and its outer surface contacts the outer surface of the internal gear ring body 105, driving the internal gear ring body 105 through friction. The body 105 rotates; the micro drive motor 315 is fixed on the upper surface of the support frame 314, and its output shaft is fixedly connected to the rubber drive wheel 317, driving the rubber drive wheel 317 to rotate, thereby driving the internal gear ring body 105 to rotate; the moving block 308 is slidably connected inside the fixed rod 307, and can slide along the axial direction of the fixed rod 307 to adjust the radial position of the processing tool 311; the inclined support rod 309 is fixed on the lower surface of the moving block 308, transmitting the sliding of the moving block 308 to the clamping block 310, thereby realizing the precise adjustment of the position of the processing tool 311.
[0056] Furthermore, a clamping block 310 is fixedly connected to one end of the inclined support rod 309. A machining tool 311 is engaged within the clamping block 310. A cooperating moving block 312 is fixedly connected to the upper surface of the clamping block 310. A placement block 313 is fixedly connected to the end of the cooperating moving block 312 away from the fixed rod 307. A placement tube 304 is fixedly connected within the placement block 313. A miniature telescopic rod is provided within the fixed rod 307, and one end of the miniature telescopic rod is fixedly connected to one side of the cooperating moving block 312. The clamping block 310 is fixed to one end of the inclined support rod 309 to engage and fix the machining tool 311, ensuring the stability of the machining tool 311's position during boring. The machining tool 311 is engaged within the clamping block 310 and can be quickly replaced according to machining requirements. The cooperating moving block 312... Fixed to the upper surface of the clamping block 310, the clamping block 310 is fixedly connected to the placement block 313 to ensure that the relative position of the placement tube 304 and the machining tool 311 is fixed, so that the coolant can be accurately sprayed to the machining area; the placement tube 304 is fixed inside the placement block 313, one end of the placement tube 304 is connected to the water tank 302, and the other end points to the cutting area of the machining tool 311, so as to transport the coolant to the cutting interface for cooling; the miniature telescopic rod is set inside the fixed rod 307, one end of which is fixedly connected to the cooperating moving block 312. The extension and retraction of the miniature telescopic rod drives the moving block 308 and the machining tool 311 to move along the axial direction of the fixed rod 307, so as to realize the automatic adjustment of the radial position of the machining tool 311 and adapt to the boring requirements of the internal gear ring body 105 with different inner diameters.
[0057] Furthermore, a water tank 302 is fixedly connected to one side of the protective frame 102, and one end of the placement pipe 304 is fixedly connected to one side of the water tank 302. Auxiliary transfer grooves 301 are provided on both sides of the workbench 101, through which two sets of lifting plates 210 can slide out. An internal gear ring body 105 is placed on the upper surface of the support plate 215 and the storage rod 214. The water tank 302 is fixed to one side of the protective frame 102 to store coolant, which is then transported to the processing area via the placement pipe 304. The auxiliary transfer grooves 301 are located on both sides of the workbench 101, providing a channel for the lifting plates 210 to extend outwards, allowing the support plate 215 and storage rod 214 to extend from both sides of the workbench 101, facilitating the placement of the large internal gear ring body 105 and preventing interference during placement due to obstruction by the support rod 204. The internal gear ring 105 can slide out from the auxiliary transfer groove 301, allowing the support plate 215 and the receiving rod 214 to extend to the outside of the worktable 101. The operator can then place the internal gear ring body 105 onto the support plate 215 and the receiving rod 214 in an open space. The internal gear ring body 105 is then lifted to the working height and moved into the worktable 101 for boring, significantly reducing the machining requirements of large workpieces. The difficulty of clamping and the operational risks.
[0058] Working principle: First, the third electric push rod 205 is activated, and its telescopic shaft drives the T-shaped block 209 to slide outward along the T-shaped groove 207 on one side of the load-bearing plate 203. The T-shaped block 209 drives the moving plate 202 and the first electric push rod 206 fixed inside the moving plate 202 to move outward horizontally in sync. The first electric push rod 206 drives the bearing plate 215 and the storage rod 214 to extend outward from the auxiliary moving grooves 301 on both sides of the workbench 101 through the lifting plate 210, extending to the outside of the workbench 101. At this time, the bearing plate 215 and the storage rod 214 are located in the open space of the workbench 101. The operator uses external equipment to place the large internal gear ring body 105 on the upper surface of the bearing plate 215 and the storage rod 214. The rods 214 together form a multi-point bearing platform, which evenly distributes the weight of the internal gear ring body 105 and prevents the workpiece from deforming due to excessive local force during placement. After the internal gear ring body 105 is placed, the third electric push rod 205 retracts in the opposite direction, driving the T-shaped block 209 to slide inward along the T-shaped groove 207, which drives the moving plate 202 and the first electric push rod 206 to reset. Then, the first electric push rod 206 is used to move the bearing plate 215 and the storage rod 214 together with the internal gear ring body 105 into the worktable 101. Through this horizontal moving method, the operator does not need to hoist the large internal gear ring from above the worktable 101, avoiding the obstruction and restriction of the protective frame 102 and the boring mechanism, which greatly reduces the difficulty of hoisting and safety risks.
[0059] Secondly, after the internal gear ring body 105 moves above the load-bearing plate 203, the first electric push rod 206 is activated, and its telescopic axis pushes the lifting plate 210 upward. The lifting plate 210 drives the bearing plate 215 and the storage rod 214 to rise synchronously, raising the internal gear ring body 105 to the predetermined processing height. During the rising process of the lifting plate 210, the upper surface of the lifting plate 210 contacts the auxiliary pressing plate 212 and applies an upward pressing force to it. The auxiliary pressing plate 212 overcomes the tension of the return spring 211 and moves upward, stretching the return spring 211 to store it. The connecting block 213, which is fixed on one side of the auxiliary extrusion plate 212, rises synchronously with the auxiliary extrusion plate 212, transmitting the lifting motion to the subsequent spring plate 322, thus achieving linkage with the internal structure of the boring drive assembly. When the internal gear ring body 105 reaches the predetermined processing height, the first electric push rod 206 stops extending and retracting, keeping the internal gear ring body 105 stably stationary at that height. The multiple support points of the bearing plate 215 and the storage rod 214 jointly bear the weight of the internal gear ring body 105, keeping it in a horizontal position during processing.
[0060] Secondly, after the internal gear ring body 105 is positioned, the second electric push rod 303 is activated. Its telescopic shaft drives the adjusting motor 306 and the fixing rod 307 to move downward, adjusting the vertical distance between the machining cutter 311 and the internal gear ring body 105. The miniature telescopic rod inside the fixing rod 307 extends or retracts according to the inner diameter of the internal gear ring body 105, driving the cooperating moving block 312 to move axially along the fixing rod 307. The cooperating moving block 312 drives the machining cutter 311 to move radially through the clamping block 310 and the inclined support rod 309, so that the cutting edge of the machining cutter 311 is accurately aligned with the internal gear ring body 105. When the inner hole is being machined, the adjusting motor 306 is started, and its rotation angle is used to adjust the actual machining area that the machining tool 311 needs to start machining in advance. The second electric push rod 303 continues to extend slowly, driving the machining tool 311 to feed downward and start boring the inner hole of the internal gear ring body 105. During the machining process, the coolant in the water tank 302 is transported to the placement block 313 through the placement pipe 304 and sprayed from the outlet end of the placement pipe 304 onto the cutting area of the machining tool 311 to cool and lubricate the machining tool 311, reduce the cutting temperature, extend the tool life, and at the same time flush the chips away from the cutting area.
[0061] Then, during the boring process, in order to make the internal gear ring body 105 rotate slowly to improve machining uniformity and reduce circumferential vibration, the connecting block 213, as it rises with the auxiliary extrusion plate 212, drives the mounting block 324 and the spring plate 322 fixed to the upper surface of the mounting block 324 to rise. One end of the spring plate 322 is fixed to the mounting block 324, and the other end is fixedly connected to the push rod 323. When the mounting block 324 rises, the spring plate 322 is compressed and undergoes elastic deformation, storing elastic potential energy. The push rod 323 transmits the elastic force of the spring plate 322 to the support frame 314, causing the support frame 314 to move towards the outer surface of the internal gear ring body 105. The rubber drive wheel 317 installed in the support frame 314, under the push of the spring plate 322, comes into close contact with the outer surface of the internal gear ring body 105, and the micro drive motor 315 starts. The output shaft drives the rubber drive wheel 317 to rotate. The rubber drive wheel 317 drives the internal gear ring body 105 to rotate slowly around its central axis through friction. Since the rubber drive wheel 317 and the outer surface of the internal gear ring body 105 are in elastic contact, it can provide sufficient driving torque to drive the internal gear ring body 105 to rotate, while avoiding damage to the surface of the internal gear ring body 105 caused by rigid contact. The slow rotation of the internal gear ring body 105 causes the machining tool 311 to continuously contact different circumferential positions of the inner hole of the internal gear ring during the cutting process, so that the tool wear is uniform, improving the machining accuracy and surface quality of the inner hole. The fourth electric push rod 321 can adjust the horizontal position of the collection frame 316 according to the diameter of the internal gear ring body 105, so that the collection frame 316 is aligned with the chip falling area to collect the chips generated during the processing and prevent the chips from scattering.
[0062] Finally, after the boring process is completed, the second electric push rod 303 retracts, driving the machining tool 311 to rise and exit the inner hole. Before the first electric push rod 206 extends and retracts in the reverse direction, the collecting frame needs to be pushed outward by the fourth electric push rod in advance to avoid motion interference with the subsequent structure. This causes the extension shaft of the first electric push rod to drive the lifting plate 210 to descend. The bearing plate 215 and the storage rod 214 carry the internal gear ring body 105 and descend synchronously. During the descent of the lifting plate 210, the pressure on the auxiliary pressing plate 212 gradually decreases. The return spring 211 releases the stored elastic potential energy, pulling the auxiliary pressing plate 212 and the connecting block 213 downward to reset. The spring plate 322 then... Reset, push rod 323 pulls support frame 314 outward, rubber drive wheel 317 disengages from outer surface of internal gear ring body 105, internal gear ring body 105 descends to workbench height 101, third electric push rod 205 starts, drives T-block 209 to slide outward along T-slot 207, drives moving plate 202 and first electric push rod 206 to move outward horizontally, so that bearing plate 215 and storage rod 214 extend from auxiliary moving groove 301 to outside of workbench 101. Operators use crane or lifting equipment in open space to lift the processed internal gear ring body 105 from bearing plate 215 and storage rod 214, completing one processing cycle.
