Description

Technical Field

[0001] This invention relates to the assembly of planetary gear mechanisms, and more specifically to an automated rolling device for planetary carrier dust seals. Background Technology

[0002] A simple planetary gear mechanism is usually called a three-component mechanism. The three components are the sun gear, the planet carrier, and the ring gear. The planet gears are mounted on the support shaft of the planet carrier and are allowed to rotate on the support shaft. In addition to rotating around the support shaft on the planet carrier, the planet gears can also rotate around the central axis of the sun gear under the drive of the planet carrier in certain working conditions.

[0003] In the prior art, the support shaft is usually inserted and fixed in a pre-set pin hole on the planetary carrier. In order to prevent external dust from entering the interior of the planetary carrier through the pin hole and affecting the normal operation of the planetary gears during use, a dustproof ring is provided on the outer end face of the planetary carrier. The dustproof ring blocks the pin hole, effectively preventing dust from seeping in and affecting the normal operation of the planetary gears.

[0004] In the existing assembly process, the dust ring is manually rolled and fixed to the outer end face of the planetary carrier. This manual method is time-consuming, and the uneven rolling is quite obvious. In addition, manually rolling the dust ring can easily lead to poor fit, and manually rolling and fixing the dust ring can easily cause injury to the operator. Summary of the Invention

[0005] The purpose of this invention is to overcome the drawbacks of the existing technology that uses manual rolling to fix dust rings, and to provide an automated rolling device for planetary carrier dust rings. This rolling device can achieve uniform pressing and fixing of dust rings on the planetary carrier, and has a good rolling fixing effect and high efficiency.

[0006] To achieve the above objectives, the present invention provides an automated rolling device for planetary carrier dust seals, comprising:

[0007] A conveyor mechanism for conveying pallets carrying planetary carriers;

[0008] A lifting mechanism is provided below the conveying mechanism. The lifting mechanism has a positioning cylinder for insertion into the planetary carrier to detach it from the bearing part of the tray.

[0009] A rotary motor, mounted on the lifting mechanism, is used to drive the positioning cylinder and rotate the planetary carrier;

[0010] A pressing mechanism is disposed above the conveying mechanism. The pressing mechanism has a guide sleeve, and when the pressing mechanism presses down, the guide sleeve presses the dustproof ring to be rolled against the upper end face of the planetary carrier.

[0011] A rolling mechanism, disposed on the pressing mechanism, is used to roll and fix the dustproof ring to the upper end surface of the planetary carrier.

[0012] Optionally, the automated rolling equipment further includes a pallet positioning component disposed on the conveying mechanism, the pallet positioning component comprising:

[0014] A check block is hinged to the support plate, and the check block and the end of the pallet in the direction of movement form a one-way check fit;

[0015] A proximity switch, mounted on the support plate, is used to detect the arrival signal of the tray;

[0016] The stop assembly is mounted on the support plate in a height-adjustable manner;

[0017] The stop component rises after receiving the arrival signal of the tray and forms a stop with the front end of the tray in the direction of movement.

[0018] Optionally, the pallet positioning component further includes:

[0019] At least one positioning mechanism is disposed on the support plate for accurately positioning the position of the tray;

[0020] The positioning mechanism includes:

[0021] The first drive cylinder is mounted on the support plate.

[0022] A positioning pin is fixed to the telescopic rod of the first drive cylinder;

[0023] The telescopic rod of the first drive cylinder extends to drive the positioning pin into the positioning hole reserved on the tray.

[0024] Optionally, the rolling mechanism includes at least one rolling wheel rotatably arranged on the side of the pressing mechanism adjacent to the conveying mechanism;

[0025] When the pressing mechanism presses down, the rolling roller can move to fit against the dustproof ring on the upper surface of the planetary carrier, and when the planetary carrier rotates, the rolling roller rotates and presses the dustproof ring tightly and fixes it to the planetary carrier.

[0026] Optionally, two rolling rollers are provided, symmetrically arranged on both sides of the guide sleeve;

[0027] The rolling mechanism includes a first mounting plate disposed on the side of the pressing mechanism near the conveying mechanism. The first mounting plate is provided with a first mounting seat on the side away from the pressing mechanism. A rolling wheel is rotatably arranged on the first mounting seat. The pressing mechanism is provided with a first electric cylinder for driving the first mounting plate to move, so that the rolling wheel mounted on the first mounting seat approaches the guide sleeve.

[0028] A second mounting plate is provided on the side of the first mounting plate adjacent to the conveying mechanism, and a second mounting seat is provided on the side of the second mounting plate away from the first mounting plate. Another rolling roller is rotatably arranged on the second mounting seat. A second electric cylinder is provided on the first mounting plate to drive the second mounting plate to move, so that the rolling roller mounted on the second mounting seat approaches the guide sleeve.

[0029] Optionally, the pressing mechanism is provided with a first linear guide rail on the side adjacent to the conveying mechanism, and the first mounting plate is provided with a first slider that forms a sliding guide engagement with the first linear guide rail;

[0030] The first mounting plate is provided with a second linear guide rail on the side adjacent to the conveying mechanism, and the second mounting plate is provided with a second slider to form a sliding guide engagement with the second linear guide rail.

[0031] Optionally, the pressing mechanism includes:

[0032] A support frame is disposed beside the conveying mechanism;

[0033] The first drive source is mounted on the support frame and is used to provide power;

[0034] A movable seat is movably mounted on the support frame;

[0035] The rolling mechanism and the guide sleeve are both located at the bottom of the movable seat. The first drive source can drive the movable seat to move, so that it moves closer to or further away from the planetary carrier on the tray in the vertical direction.

[0036] Optionally, the first driving source is a pressing cylinder, whose telescopic rod extends vertically and is fixedly connected to the movable seat;

[0037] The movable base includes a first base plate and a second base plate that are perpendicular to each other. A third slider is provided on the side of the first base plate near the support frame. The third slider and a third linear guide rail that extends vertically on the support frame form a sliding guide engagement.

[0038] The second substrate extends horizontally above the conveying mechanism, and a reinforcing plate is provided between the two side edges of the first substrate and the second substrate.

[0042] A support plate is movably disposed between the base plate and the conveying mechanism;

[0043] The rotary motor and the positioning cylinder are both arranged on the support plate. The second drive source can drive the support plate to move closer to or away from the conveying mechanism. When the support plate moves closer to the conveying mechanism until the positioning cylinder is inserted into the planetary carrier, the rotary motor drives the planetary carrier to rotate through the positioning cylinder.

[0044] Optionally, the second drive source is a lifting cylinder, whose telescopic rod extends vertically and is fixedly connected to the support plate;

[0045] The support plate extends toward the side where the base plate is located with several guide rods, and the guide rods and the limiting sleeves provided on the base plate form a guiding and limiting cooperation;

[0046] The base plate is also provided with a movable frame and a second drive cylinder for driving the movable frame to move horizontally. The movable frame extends to the side where the base plate is located with a lower support block, and the support plate extends to the side where the base plate is located with an upper support block. The second drive cylinder drives the movable frame to move horizontally to a first state where the upper end of the lower support block abuts against the lower end of the upper support block, or the second drive cylinder drives the movable frame to move horizontally to a second state where the lower support block and the upper support block are misaligned.

[0047] The above technical solution overcomes the drawbacks of the existing technology that manually presses and fixes the dustproof ring to the end face of the planetary carrier, ensuring that the dustproof ring is uniformly and reliably pressed and fixed to the end face of the planetary carrier, reducing assembly costs and improving assembly efficiency.

[0048] Based on the rolling equipment provided by this invention, the automatic rolling of dust seals on planetary carriers is realized, which can be adapted to existing planetary carrier assembly lines and improve the automation level of planetary carrier assembly.

Detailed Implementation

[0063] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0064] As mentioned above, the present invention provides an automated rolling device for planetary carrier dustproof rings, which is used to roll and fix the dustproof rings to the end face of the planetary carrier 1, thereby overcoming the various defects of the existing manual rolling and fixing method for dustproof rings.

[0065] Combination Figure 1 As shown, in this invention, the automated rolling equipment includes a conveying mechanism 100, a lifting mechanism 200, a rotary motor 220, a pressing mechanism 300, and a rolling mechanism 400.

[0066] The conveying mechanism 100 is mainly used to convey the pallet 2 carrying the planetary carrier 1; the lifting mechanism 200 is located below the conveying mechanism 100, and the lifting mechanism 200 has a positioning cylinder 210 for inserting into the planetary carrier 1 to disengage it from the supporting part of the pallet 2. The rotary motor 220 is located on the lifting mechanism 200 and is used to drive the positioning cylinder 210 and drive the planetary carrier 1 to rotate; the pressing mechanism 300 is located above the conveying mechanism 100, and the pressing mechanism 300 has a guide sleeve 310. When the pressing mechanism 300 presses down, the guide sleeve 310 presses the dustproof ring to be rolled against the upper end face of the planetary carrier 1; the rolling mechanism 400 is located on the pressing mechanism 300 and is used to roll and fix the dustproof ring to the upper end face of the planetary carrier 1.

[0067] In practical use, the automated rolling equipment provided by this invention, after the conveying mechanism 100 delivers the pallet 2 to the designated position, the lifting mechanism 200 lifts and fixes the planetary carrier 1 carried in the pallet 2 relative to it through the positioning cylinder 210. Then, the pressing mechanism 300 presses down until the guide sleeve 310 is fitted onto the upper end of the planetary carrier 1. Next, the rolling mechanism 400 operates and adheres tightly to the dustproof ring. Then, the rotary motor 220 drives the planetary carrier 1 to rotate through the positioning cylinder 210, realizing the uniform pressing of the dustproof ring by the rolling mechanism 400. The rolling equipment provided by this invention overcomes the shortcomings of the current manual rolling and fixing of dustproof rings, which is time-consuming and has poor rolling and fixing effect.

[0068] Furthermore, the automated rolling equipment provided by this invention enables continuous production of planetary gear mechanisms. After the aforementioned dust ring rolling and fixing process is completed, each mechanism returns to its initial position, and the pallet 2 continues to support the planetary carrier 1. It can then be transported to the next workstation via the conveying mechanism 100, thereby improving the assembly efficiency of the planetary gear mechanism.

[0069] It should be noted that in this invention, the planetary carrier 1 can only be lifted after the conveying mechanism 100 has conveyed the pallet 2 carrying the planetary carrier 1 into place; in order to position the pallet 2, combined with Figure 3 As shown, in some embodiments, the automated rolling equipment further includes a pallet positioning component 500 disposed on the conveying mechanism 100. The pallet positioning component 500 includes a support plate 510, a check block 520, a proximity switch, and a stop component 530. The support plate 510 is disposed on the conveying mechanism 100, specifically at the position where the pallet 2 is to be positioned.

[0070] The check block 520 is hinged to the support plate 510 and forms a one-way check fit with the end of the pallet 2 in the direction of movement. For details, please refer to [link / reference needed]. Figure 3The check block 520 is rotatably arranged on the support plate 510 via a U-shaped mounting base 521, and the hinge axis between the check block 520 and the U-shaped mounting base 521 is located at the eccentric position of the check block 520, so that it presents a state of first low and then high along the conveying direction of the conveying mechanism 100. When the pallet 2 is conveyed forward by the conveying mechanism 100 and passes the check block 520, the end of the "low" position is in a clearance position with the pallet 2, while the end of the "high" position is pressed down by the pallet. After the pallet 2 has completely passed, the check block 520 returns to its original position, and at this time the end of the "high" position is blocked by the end of the pallet 2 in the moving direction.

[0071] The proximity switch is disposed on the support plate 510 and is used to detect the arrival signal of the tray 2; the stop assembly 530 is disposed on the support plate 510 in a height-reducing manner, wherein the stop assembly 530 rises after receiving the arrival signal of the tray 2 and forms a stop engagement with the front end of the tray 2 in the direction of movement. In some embodiments, the stop assembly 530 specifically includes a support base 531 mounted on a support plate 510. A rotating arm 532 is hinged to the support base 531. One end of the rotating arm 532 is provided with a stop wheel 533, and the other end is connected to the telescopic rod of a third drive cylinder 534 mounted on the support plate 510. When the telescopic rod of the third drive cylinder 534 extends, it drives the rotating arm 532 to rotate, so that the stop wheel 533 mounted on its suspended end is in a clearance position with the tray 2. When the telescopic rod of the third drive cylinder 534 retracts, it drives the rotating arm 532 to rotate, so that the stop wheel 533 mounted on its suspended end forms a stop engagement with the front end of the tray 2 in the direction of movement.

[0072] The pallet positioning component 500 accurately stops the pallet 2 carrying the planetary carrier 1 at the rolling and fixing position of the dustproof ring.

[0073] Furthermore, to ensure precise positioning of the pallet 2, the pallet positioning assembly 500 further includes at least one positioning mechanism 540. The positioning mechanism 540 is disposed on the support plate 510 and specifically includes a first drive cylinder 541 and a positioning pin 542. The first drive cylinder 541 is disposed on the support plate 510, and the positioning pin 542 is fixed to the telescopic rod of the first drive cylinder 541. The telescopic rod of the first drive cylinder 541 extends to drive the positioning pin 542 into a pre-drilled positioning hole on the pallet 2. This positioning mechanism 540 ensures precise positioning of the pallet 2. After the dustproof ring is rolled and fixed, the telescopic rod of the first drive cylinder 541 retracts to drive the positioning pin 542 to a clearance position from the pre-drilled positioning hole on the pallet 2. In a further preferred embodiment, two positioning mechanisms 540 are provided, correspondingly arranged diagonally on the support plate 510.

[0074] According to the automated rolling equipment provided by the present invention, the conveying mechanism 100 is used to convey the tray 2 carrying the planetary carrier 1. The conveying mechanism 100 can be a cantilever roller line commonly used by those skilled in the art.

[0075] For details, please refer to Figure 2 As shown, the conveying mechanism 100 includes two parallel and spaced support beams 110, and a crossbeam (not shown in the figure) is provided between the two support beams 110.

[0076] Two support beams 110 are each rotatably equipped with a rotating shaft 120. Multiple rotating shafts 120 are arranged at intervals along the length of the support beams 110. Each end of the rotating shaft 120 located between the two support beams 110 is provided with a support roller 121 for supporting the tray 2.

[0077] Both support beams 110 are equipped with transmission roller shafts 130 on their outer sides. The transmission roller shafts 130 are provided with driving bevel gears 131 arranged at intervals along their length. The end of the rotating shaft 120 extending out of the support beam 110 is provided with a driven bevel gear 122, which meshes with the driving bevel gear 131. The transmission roller shafts 130 are connected to a drive motor to obtain rotational power.

[0078] A synchronous roller shaft 140 is also provided between the two support beams 110. Synchronous gears 141 are provided at both ends of the synchronous roller shaft 140. The synchronous gears 141 at both ends of the synchronous roller shaft 140 mesh with the active bevel gears 131 on the transmission roller shaft 130 on the outer side of the two support beams 110. In this way, the synchronicity of the rotation of the rotating shaft 120 on the two support beams 110 is ensured.

[0079] In this invention, the function of the rolling mechanism 400 is to cooperate with the rotating planetary carrier 1 to roll and fix the dustproof ring to the end face of the planetary carrier 1. In a specific embodiment of this invention, the rolling mechanism 400 includes at least one rolling roller 410 rotatably arranged on the side of the pressing mechanism 300 adjacent to the conveying mechanism 100; when the pressing mechanism 300 presses down, the rolling roller 410 can move to press against the dustproof ring on the upper end face of the planetary carrier 1, and when the planetary carrier 1 rotates, the rolling roller 410 rotates and presses and fixes the dustproof ring to the planetary carrier 1.

[0080] Furthermore, in order to improve the efficiency of rolling, two rolling rollers 410 are provided in this invention, and the two rolling rollers 410 are symmetrically arranged on both sides of the guide sleeve 310. Through the above technical solution, the instability caused by the single-point pressure of the rolling rollers 410 on the planetary carrier 1 can also be avoided. The two rolling rollers 410 always apply pressure at relatively symmetrical points, ensuring the stability of the planetary carrier 1 when it rotates.

[0081] In this invention, the rolling mechanism 400 operates only after the pressing mechanism 300 has been pressed into place, causing the rolling roller 410 to move to the dustproof ring that is close to the upper surface of the planetary carrier 1. This is one specific implementation of the movement of the rolling mechanism 400, combined with... Figure 7 , 8 As shown, the rolling mechanism 400 includes a first mounting plate 420 disposed on the side of the pressing mechanism 300 near the conveying mechanism 100. The first mounting plate 420 is provided with a first mounting seat 421 on the side away from the pressing mechanism 300. A rolling wheel 410 is rotatably arranged on the first mounting seat 421. The pressing mechanism 300 is provided with a first electric cylinder 320 for driving the first mounting plate 420 to move, so that the rolling wheel 410 mounted on the first mounting seat 421 moves closer to the guide sleeve 310.

[0082] A second mounting plate 422 is provided on the side of the first mounting plate 420 adjacent to the conveying mechanism 100. A second mounting seat 4221 is provided on the side of the second mounting plate 422 away from the first mounting plate 420. Another rolling roller 410 is rotatably arranged on the second mounting seat 4221. A second electric cylinder 423 is provided on the first mounting plate 420 to drive the second mounting plate 422 to move, so that the rolling roller 410 mounted on the second mounting seat 4221 approaches the guide sleeve 310.

[0083] Through the above technical solution, the driving action of the first electric cylinder 320 and the second electric cylinder 423 causes both rolling rollers 410 to approach the guide sleeve 310 and abut against the dust ring on the end face of the planetary carrier 1. When the rotary motor 220 drives the planetary carrier 1 to rotate through the positioning cylinder 210, the two rolling rollers 410 simultaneously roll the dust ring, evenly pressing and fixing it to the end face of the planetary carrier 1.

[0084] Furthermore, in order to ensure the stability of the first mounting plate 420 and the second mounting plate 422 during reciprocating movement, the pressing mechanism 300 is provided with a first linear guide rail 330 on the side adjacent to the conveying mechanism 100, and the first mounting plate 420 is provided with a first slider 424 to form a sliding guide engagement with the first linear guide rail 330; more preferably, two first linear guide rails 330 are arranged in parallel at intervals.

[0085] The first mounting plate 420 is provided with a second linear guide rail 425 on the side adjacent to the conveying mechanism 100. The second mounting plate 422 is provided with a second slider 4222, which forms a sliding guide engagement with the second linear guide rail 425. More preferably, two second linear guide rails 425 are arranged in parallel at intervals.

[0086] According to the automated rolling equipment provided by the present invention, the pressing mechanism 300 moves downward and cooperates with the lifting mechanism 200 to clamp and fix the planetary carrier 1 so as to perform the pressing and fixing operation of the dustproof ring. As a specific embodiment of the pressing mechanism 300, combined with... Figure 4 , 5 As shown, the pressing mechanism 300 includes a support frame 340, a first drive source, and a movable seat 350. The support frame 340 is disposed beside the conveying mechanism 100 and mainly serves to support and fix components such as the first drive source and the movable seat 350. The first drive source is disposed on the support frame 340 and is used to provide power. The movable seat 350 is movably disposed on the support frame 340. The rolling mechanism 400 and the guide sleeve 310 are both disposed at the bottom of the movable seat 350. The first drive source can drive the movable seat 350 to move, so that it moves closer to or further away from the planetary carrier 1 on the tray 2 in the vertical direction.

[0087] It should be noted that in this invention, the guide sleeve 310 can be fitted onto the upper end of the planetary carrier 1 when the pressing mechanism 300 presses down, pressing the dustproof ring against the upper end face of the planetary carrier 1. Furthermore, when the rotary motor 220 provides power to drive the planetary carrier 1 to rotate, the guide sleeve 310 can provide auxiliary support. Please refer to [link / reference]. Figure 6 As shown, in some embodiments, the guide sleeve 310 includes a guide outer cylinder 311 and a guide inner cylinder 312 rotatably arranged inside the guide outer cylinder 311. The upper end of the guide outer cylinder 311 is fixed on the movable seat 350, and the upper and lower ends of the guide inner cylinder 312 are rotatably arranged inside the guide outer cylinder 311 via the first bearing 313. When the pressing mechanism 300 presses down, the guide inner cylinder 312 is sleeved on the upper end of the planetary carrier 1.

[0088] In some embodiments, the first driving source is a pressing cylinder 360, the telescopic rod of which extends vertically and is fixedly connected to the movable seat 350. In actual use, the reciprocating motion of the movable seat 350 on the support frame 340 can be realized by extending and retracting the telescopic rod of the pressing cylinder 360.

[0089] In some embodiments, the movable base 350 includes a first substrate 351 and a second substrate 352 that are perpendicular to each other. A third slider 3511 is provided on the side of the first substrate 351 adjacent to the support frame 340. The third slider 3511 and a third linear guide rail 341 extending vertically on the support frame 340 form a sliding guide engagement. More preferably, two third linear guide rails 341 are arranged in parallel at intervals.

[0090] The second substrate 352 extends horizontally above the conveying mechanism 100. The second substrate 352 serves as the mounting position for the rolling mechanism 400 and the guide sleeve 310, and can be easily used in conjunction with the lifting mechanism 200 to clamp the planetary carrier 1 when pressing down.

[0091] A reinforcing plate 353 is provided between the two sides of the first substrate 351 and the second substrate 352, thereby ensuring the structural strength of the entire movable seat 350.

[0092] According to the automated rolling equipment provided by the present invention, the lifting mechanism 200 is used to lift the planetary carrier 1 on the tray 2, and cooperates with the pressing mechanism 300 and the rolling mechanism 400 to press and fix the dustproof ring at the end face of the planetary carrier 1.

[0093] In some embodiments, combined with Figure 9 As shown, the lifting mechanism 200 includes a base plate 230, a second drive source, and a support plate 240. The base plate 230 is disposed below the conveying mechanism 100. The second drive source is disposed on the base plate 230 to provide power. The support plate 240 is movably disposed between the base plate 230 and the conveying mechanism 100. The rotary motor 220 and the positioning cylinder 210 are both arranged on the support plate 240. The second drive source can drive the support plate 240 to move closer to or away from the conveying mechanism 100. When the support plate 240 moves closer to the conveying mechanism 100 until the positioning cylinder 210 is inserted into the planetary carrier 1, the rotary motor 220 drives the planetary carrier 1 to rotate through the positioning cylinder 210.

[0094] Please see Figure 11 In this invention, the positioning cylinder 210 not only lifts the planetary carrier 1 from the tray 2, but also transmits the power of the rotary motor 220 to the planetary carrier 1 to make it rotate, thereby cooperating with the rolling mechanism 400 to achieve the pressing and fixing of the dustproof ring.

[0095] The lower end of the positioning cylinder 210 is rotatably arranged on the support plate 240, and a driven gear 211 arranged along the same center line is also provided at the lower end of the positioning cylinder 210. The power output end of the rotary motor 220 is provided with a driving gear 221, and the driving gear 221 meshes with the driven gear 211.

[0096] In some embodiments, the support plate 240 is provided with a stepped hole 242, and a connecting sleeve 243 is inserted and fixed in the stepped hole 242. The inner ring of the driven gear 211 is provided with a connecting sleeve 212 extending away from the positioning sleeve 210. The connecting sleeve 212 is rotatably arranged in the connecting sleeve 243 via a second bearing 213. Preferably, two second bearings 213 are arranged at intervals along the length direction of the connecting sleeve 212.

[0097] The driven gear 211 has a stepped portion on one end face near the stepped hole 242, and a thrust ball bearing 214 is provided at the stepped portion. The inner ring of the thrust ball bearing 214 is fixed on the connecting sleeve 243.

[0098] Furthermore, in this invention, to ensure that the rotational power of the positioning cylinder 210 can be reliably transmitted to the planetary carrier 1, the upper end of the positioning cylinder 210 is provided with a pin 215 extending radially therein. When the positioning cylinder 210 is inserted into the planetary carrier 1, a transmission engagement is achieved between the positioning cylinder 210 and the planetary carrier 1 through the pin 215. Preferably, multiple pins 215 are arranged at intervals along the circumference of the positioning cylinder 210, for example, three.

[0099] In some embodiments, the second driving source is a lifting cylinder 250, the telescopic rod of the lifting cylinder 250 extends vertically and is fixedly connected to the support plate 240. In actual use, the support plate 240 can be raised or lowered by extending and retracting the telescopic rod of the lifting cylinder 250.

[0100] It should be noted that proximity switches are provided for both the extended and retracted positions of the lifting cylinder 250 to control the closing of the lifting cylinder 250.

[0101] Furthermore, in some embodiments, to ensure the stability of the support plate 240 during reciprocating movement, the support plate 240 has several guide rods 241 extending towards the base plate 230. The guide rods 241 and the limiting sleeves 231 provided on the base plate 230 form a guiding and limiting engagement. Specifically, four guide rods 241 are provided.

[0102] It should be noted that, in this invention, after the support plate 240 is lifted by the second driving source, it needs to be held for a certain period of time. In order to avoid the second driving source bearing pressure for a long time, in some embodiments of this invention, the base plate 230 is also provided with a movable frame 260 and a second driving cylinder 270 for driving the movable frame 260 to move horizontally. The movable frame 260 extends a lower support block 261 towards the side where the base plate 230 is located, and the support plate 240 extends an upper support block 244 towards the side where the base plate 230 is located. The second driving cylinder 270 drives the movable frame 260 to move horizontally to a first state where the upper end of the lower support block 261 abuts against the lower end of the upper support block 244, or the second driving cylinder 270 drives the movable frame 260 to move horizontally to a second state where the lower support block 261 and the upper support block 244 are misaligned.

[0103] In practical use, such as Figure 10As shown, when the second drive source lifts the support plate 240, the second drive cylinder 270 drives the movable frame 260 to move, so that the lower support block 261 on the movable frame 260 moves to the bottom of the upper support block 244 to achieve support, thus avoiding the second drive source from bearing pressure for a long time.

[0104] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the inventive concept, various simple modifications can be made to the technical solutions of the present invention. To avoid unnecessary repetition, the present invention will not describe the various possible combinations separately. However, these simple modifications and combinations should also be considered as the content disclosed in the present invention and are all within the protection scope of the present invention.
