Description

Technical Field

[0001] This utility model relates to the field of handling mechanisms, specifically a handling mechanism for workpiece transfer equipment. Background Technology

[0002] When producing pulley workpieces in a workshop, a workpiece handling mechanism is typically used to transfer the blank to the machining station for spin forming. The machining station uses high-speed rotary pressing to form a groove structure of predetermined specifications on the outer wall of the workpiece. Currently, the industry commonly uses robotic arms as standard handling equipment. These automated devices precisely position the blanks conveyed by the feeding conveyor line to the machining area through clamping actions. After the outer wall machining process is completed, the finished part is then transferred to the output conveyor line to complete the production cycle.

[0003] However, this conventional operating method has significant technical drawbacks: First, the procurement and maintenance of dedicated robotic arm systems significantly increases the overall cost of the production line; second, during material transfer, the equipment relies solely on the frictional resistance between the grippers and the workpiece surface to maintain gripping stability. When encountering large workpieces or requiring long-distance transport, this clamping method presents a double risk—the workpiece may fall and be damaged due to insufficient frictional resistance, or the workpiece surface may be damaged due to over-gripping. Especially for finished parts, the outer wall is easily damaged, rendering them unusable, which poses a severe challenge to controlling the production yield.

[0004] The research objective of this utility model is to design a handling mechanism for workpiece transfer equipment to address the problems existing in the prior art. Utility Model Content

[0005] This invention provides a handling mechanism for workpiece transfer equipment, which can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A handling mechanism for a workpiece transfer device includes: a moving drive and a handling device;

[0008] The conveying device includes:

[0009] A movable seat is used to receive a corresponding workpiece, and the movable seat is provided with a limiting structure for limiting the workpiece.

[0010] The lower drive component is connected between the movable base and the movable drive device;

[0011] The upper drive unit is connected to the lower drive unit and is driven to move up and down by the lifting drive device and to move laterally by the telescopic drive device.

[0012] A clamping device is connected to the upper driving member and located above the movable seat. The clamping device includes a clamping member driven by the clamping driving device for clamping the workpiece. The movable driving device is used to drive the lower driving member and the upper driving member to move the movable seat and the clamping member laterally to the corresponding feeding station, transfer station and discharge station. The transfer station intervals correspond to the corresponding processing stations.

[0013] When the workpiece is located on the movable seat, the limiting structure limits the workpiece, and the clamping member clamps the workpiece.

[0014] When the movable seat moves to the transfer station, the clamping member is used to clamp the workpiece on the movable seat to the processing station or to clamp the workpiece on the processing station to the movable seat.

[0015] Furthermore, the mobile drive device includes a rotating seat driven by a telescopic hydraulic cylinder, and the conveying device is provided with two sets of feeding mechanism and unloading mechanism arranged at an angle between them; the rotating seat is used to drive the moving seats of the feeding mechanism and the unloading mechanism to rotate and move to the feeding station and the transfer station respectively, or to drive the moving seats of the feeding mechanism and the unloading mechanism to rotate and move to the transfer station and the discharge station respectively.

[0016] Furthermore, the top of the moving seat of both the loading mechanism and the unloading mechanism is recessed and has a limiting groove with an opening on one side for inputting and outputting workpieces, and the limiting structure includes the limiting groove.

[0017] Furthermore, the limiting structure also includes a pressure sensor disposed in the limiting groove and an electromagnet disposed in the movable seat for attracting the workpiece by electromagnetic induction.

[0018] Furthermore, the workpiece has a through hole running vertically through its middle section. The clamping device also includes a drive seat connected to the upper drive member. There are two clamping members. The clamping drive device is located inside the drive seat, and the two drive ends are connected to the upper ends of the two clamping members after sliding through the drive seat via several sliding rods. A buffer spring is sleeved on the sliding rod and placed between the drive seat and the clamping member. The two clamping members are designed as vertical plates, and both facing sides are provided with anti-slip layers that are adapted to the curvature of the outer wall of the workpiece.

[0019] Furthermore, a vertically extending airbag with an outer diameter smaller than the inner diameter of the perforation is fixedly provided at the bottom center of the drive seat, and opposing extrusion members are respectively protruding on the opposing sides of the two clamping members; when the upper drive member moves to the point where the airbag extends into the perforation of the workpiece and the two clamping members correspond to the outer wall of the workpiece, the clamping drive device drives the two clamping members to clamp the outer wall of the workpiece, and the two extrusion members move towards each other to extrude the upper part of the airbag, so that the lower part of the airbag bulges up and sticks tightly to the inner wall of the perforation.

[0020] Furthermore, the extrusion member is a laterally extending plate, and the opposing sides of the two extrusion members are recessed to form extrusion portions that are adapted to the upper outer wall of the airbag, and both extrusion portions are provided with flexible layers.

[0021] Furthermore, the upper driving member and the lower driving member are arranged vertically and horizontally, and a lifting seat is provided between the upper driving member and the lower driving member. One end of the lifting seat extends laterally to form a sliding sleeve for laterally sliding insertion of the upper driving member, and the other end is folded downward and slidably connected to the top of the lower driving member. The lifting driving device is located on the top of the lower driving member and is used to drive the lifting seat to move up and down. The telescopic driving device is located inside the sliding sleeve and is used to drive the upper driving member to move laterally.

[0022] Furthermore, the mobile drive device also includes a base for rotatably mounting the rotating seat. The bottom center of the lower drive member is supported on the base by a support roller, and the top center is provided with a support cylinder that is vertically coaxial with the support roller. The bottom center of the lower drive member is provided with a sleeve that extends vertically and slides up and down on the outside of the support cylinder. The support cylinder is provided with support springs at its upper and lower ends that are positioned between the sliding sleeve and the lower drive member.

[0023] The beneficial effects of this utility model are:

[0024] 1. During workpiece handling: When the workpiece is on the moving seat, the limiting structure limits its position, the clamping component grips the workpiece, and the moving drive device drives the lower and upper drive components together to move the moving seat and clamping component laterally. Thus, the workpiece is doubly secured by the limiting structure of the moving seat and the clamping component, allowing the upper and lower drive components to stably move the rotating seat and workpiece laterally to the transfer station. During this process, due to the supporting and limiting effect of the moving seat, the clamping component does not grip the workpiece in mid-air, eliminating the risk of the workpiece slipping and being damaged between the clamping components. This greatly improves the stability of workpiece handling to the transfer station. Furthermore, When the moving seat moves to the transfer station, the clamping components are used for vertical lifting and lateral movement to clamp the workpiece on the moving seat to the processing station, or to clamp the workpiece on the processing station to the moving seat. This allows the clamping components to perform a short-stroke suspended clamping of the workpiece between the transfer station and the processing station, which is spaced apart. This greatly shortens the stroke and duration of the clamping components' suspended clamping of the workpiece, minimizing the risk of the workpiece slipping and being damaged during transport. Furthermore, this configuration allows for appropriate adjustment of the clamping force of the clamping components, avoiding excessive clamping force that could damage the workpiece. This improves the stability of the transport mechanism for workpiece transport, ensuring a high yield rate in workshop production.

[0025] 2. When the rotating seat drives the moving seats of the loading mechanism and the unloading mechanism to the feeding station and the transfer station respectively, the feeding mechanism inputs the next-level workpiece blank to the moving seat of the loading mechanism, and the clamping parts of the unloading mechanism clamp the previous-level workpiece finished product on the processing station to the moving seat of the unloading mechanism. When the rotating seat drives the moving seats of the loading mechanism and the unloading mechanism to the transfer station and the discharge station respectively, the clamping parts of the loading mechanism clamp the next-level workpiece blank on the moving seat to the processing station, and the discharge mechanism outputs the previous-level workpiece finished product located on the moving seat of the unloading mechanism. By making the transfer guide rails arc-shaped, not only can the moving efficiency of the moving seat be improved, but the footprint of the moving drive device can also be reduced, thus improving the structural compactness. Through the division of labor and cooperation between the moving seats of the loading and unloading mechanisms, the unloading and unloading of the finished workpieces of the previous stage and the feeding and loading of the blanks of the next stage can be realized during the rotation of the loading and unloading mechanisms driven by the moving drive device. This greatly reduces the waiting time for workpiece loading, unloading and transportation, and improves the working efficiency of the transportation device while reducing its energy consumption, thus greatly improving the workpiece transportation efficiency.

[0026] 3. When the moving seat of the feeding mechanism moves to the feeding station, the corresponding feeding mechanism inputs the workpiece blank into the limiting groove. When the moving seat of the unloading mechanism moves to the unloading station, the corresponding unloading mechanism outputs the finished workpiece from the limiting groove. When the pressure sensor in the limiting groove senses that the workpiece has arrived, the electromagnet is energized to attract the workpiece in the limiting groove. When the moving seat of the unloading mechanism moves to the unloading station, the electromagnet is de-energized, breaking the attraction and fixation of the workpiece. Thus, the single-sided opening of the limiting groove facilitates the movement of the workpiece into and out. Furthermore, the addition of the electromagnet helps to fix the workpiece within the limiting groove, improving the limiting effect of the groove on the workpiece, increasing the stability of the workpiece on the moving seat, and consequently improving the stability of workpiece handling.

[0027] 4. When the upper drive component descends until the airbag extends into the perforation of the workpiece, the clamping drive device drives the two clamping components to clamp the outer wall of the workpiece. The two squeezing components move towards each other, squeezing the upper part of the airbag so that the lower part of the airbag bulges up and adheres tightly to the inner wall of the perforation. Thus, by adding the airbag and squeezing components, the drive seat not only adheres tightly to the outer wall of the workpiece through the anti-slip layer of the clamping components, but also adheres tightly to the inner wall of the perforation through the lower part of the airbag bulging up by the squeezing components. This greatly increases the contact area between the clamping device and the inner and outer walls of the workpiece when clamping it, enabling highly stable clamping and handling of the workpiece. Furthermore, the flexible and high-friction airbag and anti-slip layer respectively contact the inner and outer walls of the workpiece without causing wear or the risk of damage due to excessive squeezing.

[0028] 5. The flexible layer prevents the airbag from being damaged when the extruder squeezes the airbag through the extrusion section, thus reducing the life of the airbag and improving the stability of the extruder squeezing the airbag.

[0029] 6. By adding support rollers, the middle part of the lower drive component is supported, improving the structural stability of the lower drive component. Simultaneously, the support columns and cylinders, which are vertically coaxial with the support rollers and slidably connected, along with the support springs fitted between them and positioned at both ends between the sliding sleeve and the lower drive component, achieve coaxial support for the sliding sleeve, thus improving the structural stability of the sliding sleeve and the upper drive component. This enhances the stability of the lower and upper drive components as they move together, driving the moving seat and clamping component along the transfer guide. Furthermore, when the lifting seat rises and the clamping component of the upper drive component is suspended, clamping the workpiece, the support rollers and support springs still provide coaxial support for the sliding sleeve. Therefore, the addition of support rollers and support springs comprehensively improves the support strength for both the upper and lower drive components, enhancing their structural stability and ultimately improving the stability of workpiece handling.

[0037] Reference Figure 1-7 As shown, a handling mechanism for a workpiece transfer device:

[0038] The workpiece transfer equipment includes: a transfer guide rail 1, a feeding mechanism 7 and a discharging mechanism 8. The transfer guide rail 1 includes a transfer station 11 with a spacing corresponding to the corresponding processing station 6, as well as a feeding station 12 and a discharging station 13.

[0039] The transport mechanism includes:

[0040] The mobile drive unit 3 and the conveying device 2;

[0041] The conveying device 2 includes:

[0042] The movable seat 21 is used to receive the corresponding workpiece. The movable seat 21 is provided with a limiting structure for limiting the workpiece. Specifically, the bottom of the movable seat 21 is rolled and clamped on both sides of the transfer guide rail 1 by a number of limiting rollers 211 so that the movable seat 21 can slide along the transfer guide rail 1.

[0043] The lower drive component 22 is connected between the movable base 21 and the movable drive device 3;

[0044] The upper drive component 23 is connected to the lower drive component 22 and is driven to move up and down by the lifting drive device and to move laterally by the telescopic drive device.

[0045] A clamping device 24 is connected to the upper driving member 23 and located above the movable seat 21. The clamping device 24 includes a clamping member 241 driven by the clamping driving device 242 to clamp the workpiece. The movable driving device 3 is used to drive the lower driving member 22 and the upper driving member 23 to move the movable seat 21 and the clamping member 241 laterally to the corresponding feeding station 12, transfer station 11 and discharge station 13. The transfer station 11 is spaced at corresponding processing stations 6.

[0046] The above-described structure allows for the following during workpiece handling:

[0047] When the workpiece is located on the movable seat 21, the limiting structure limits the workpiece, the clamping member 241 clamps the workpiece, and the moving drive device 3 drives the lower drive member 22 and the upper drive member 23 to move the movable seat 21 and the clamping member 241 along the transfer guide rail 1. Thus, the workpiece is doubly fixed by the limiting structure of the movable seat 21 and the clamping member 241, so that the upper drive member 23 and the lower drive member 22 can stably drive the rotating seat and the workpiece to move along the transfer guide rail 1 to the transfer station 11. During this period, due to the supporting and limiting effect of the movable seat 21, the clamping member 241 does not suspend and grip the workpiece, so there is no risk of the workpiece slipping and being damaged between the clamping members 241, which can greatly improve the stability of the workpiece being transported to the transfer station 11.

[0048] Based on this, when the movable seat 21 moves to the transfer station 11, the clamping member 241 is used for vertical lifting and horizontal movement to clamp the workpiece on the movable seat 21 to the processing station 6 or to clamp the workpiece on the processing station 6 to the movable seat 21. This allows the clamping member 241 to perform a short-stroke suspended clamping of the workpiece between the transfer station 11 and the processing station 6, which is spaced apart. This greatly shortens the stroke and duration of the clamping member 241 in the suspended clamping of the workpiece, minimizing the risk of the workpiece slipping and being damaged during transport. Furthermore, this setting allows for an appropriate reduction in the clamping force of the clamping member 241, preventing excessive clamping force from damaging the workpiece and improving the stability of the transport mechanism for workpiece transport, thereby ensuring the yield rate of workshop production.

[0049] To improve the workpiece handling efficiency of the conveying mechanism, the transfer guide rail 1 is arc-shaped with its opening facing away from the processing station 6. The transfer station 11 is located in the middle of the transfer guide rail 1. The feeding station 12 and the discharging station 13 are symmetrically located on both sides of the transfer station 11. The moving drive device 3 includes a rotating seat 32 driven by a telescopic cylinder 31. The conveying device 2 is equipped with two sets of loading mechanism 4 and unloading mechanism 5, which are respectively arranged at an angle to each other. The above structure can achieve the following: when the rotating seat 32 drives the moving seats 21 of the loading mechanism 4 and the unloading mechanism 5 to move to the processing station 6 respectively... When the feeding station 12 and the transfer station 11 are in operation, the feeding mechanism 7 inputs the next-level workpiece blank to the moving seat 21 of the loading mechanism 4, and the clamping member 241 of the unloading mechanism 5 clamps the finished workpiece of the previous level on the processing station 6 to the moving seat 21 of the unloading mechanism 5. When the rotating seat 32 drives the moving seat 21 of the loading mechanism 4 and the unloading mechanism 5 to move to the transfer station 11 and the discharge station 13 respectively, the clamping member 241 of the loading mechanism 4 clamps the next-level workpiece blank on the moving seat 21 to the processing station 6, and the discharge mechanism 8 outputs the finished workpiece of the previous level located on the moving seat 21 of the unloading mechanism 5. By setting the transfer guide rail 1 to an arc shape, not only can the moving efficiency of the moving seat 21 be improved, but the footprint of the moving drive device 3 can also be reduced, improving the structural compactness. Through the division of labor and cooperation between the moving seat 21 of the loading mechanism 4 and the unloading mechanism 5, the unloading and unloading of the upper-level finished workpiece and the feeding and loading of the lower-level workpiece blank can be realized during the process of the moving drive device 3 driving the loading mechanism 4 and the unloading mechanism 5 to rotate once. This greatly reduces the waiting time for workpiece feeding, unloading and transportation, and improves its working efficiency while reducing the working energy consumption of the transportation device 2, thus greatly improving the workpiece transportation efficiency.

[0050] To improve the limiting effect of the limiting structure, the top of the moving seat 21 of both the feeding mechanism 4 and the unloading mechanism 5 is recessed with a limiting groove 212 with one side opening for inputting and outputting workpieces. The limiting structure includes a pressure sensor located in the limiting groove 212 and an electromagnet located in the moving seat 21 for attracting the workpiece by electromagnetic induction. When the moving seat 21 of the feeding mechanism 4 moves to the feeding station 12, the corresponding feeding mechanism 7 inputs the workpiece blank into the limiting groove 212. When the moving seat 21 of the unloading mechanism 4 moves to the unloading station 13, the corresponding unloading mechanism 8 outputs the finished workpiece from the limiting groove 212. When the pressure sensor in the limiting groove 212 senses that the workpiece is in place, the electromagnet is energized to attract the workpiece in the limiting groove 212. When the moving seat 21 of the unloading mechanism 5 moves to the unloading station 13, the electromagnet is de-energized, breaking the attraction and fixation of the workpiece. The single-sided opening of the limiting groove 212 facilitates the movement of the workpiece into and out. The addition of an electromagnet helps to fix the workpiece in the limiting groove 212, thereby improving the limiting effect of the limiting groove 212 on the workpiece, improving the stability of the workpiece on the moving seat 21, and thus improving the stability of workpiece handling.

[0051] Specifically, the workpiece has a through hole running vertically through its middle section. In this embodiment, the workpiece is a pulley, and the through hole is a connecting hole in the middle of the pulley. The clamping device 24 also includes a drive seat 243 connected to the upper drive member 23. There are two clamping members 241. The clamping drive device 242 is located inside the drive seat 243, and its two drive ends are connected to the upper ends of the two clamping members 241 after sliding through the drive seat 243 via several sliding rods 244. A buffer spring 245 is sleeved on the sliding rod 244 and is positioned between the drive seat 243 and the clamping member 241. The two clamping members 241 are vertically plate-shaped, and both facing sides are provided with anti-slip layers 246 that are adapted to the curvature of the outer wall of the workpiece. The anti-slip layers 246 can be made of flexible and high-friction rubber or other materials. Thus, the buffer spring 245 can prevent the workpiece from being damaged by excessive speed and force when the two clamping parts 241 clamp each other. The anti-slip layer 246 can increase the contact area and friction between the clamping parts 241 and the outer wall of the workpiece when clamping it, which can greatly improve the stability of the clamping parts 241 in clamping the workpiece and reduce the risk of the workpiece sliding down and falling when the clamping parts 241 are suspended in the air.

[0052] To improve the clamping stability of the clamping device 24, a vertically extending airbag 247 with an outer diameter smaller than the inner diameter of the perforation is fixedly provided at the bottom center of the drive base 243. Two opposing clamping members 241 are respectively provided with opposing extending extrusion members 248. This structure enables the following: when the upper drive member 23 moves to the point where the airbag 247 extends into the perforation of the workpiece and the two clamping members 241 correspond to the outer wall of the workpiece, the clamping drive device 242 drives the two clamping members 241 to clamp onto the outer wall of the workpiece. The two extrusion members 248 move towards each other, extruding the upper part of the airbag 247, causing the lower part of the airbag 247 to bulge and adhere tightly to the inner wall of the perforation. Specifically, the airbag 247 can be a flexible rubber airbag 247 with high friction. An inflation port for inflation can be provided on one side of the upper end of the airbag 247 to facilitate replenishment of air when the internal gas is insufficient after prolonged use. By adding the airbag 247 and the squeezing member 248, the drive seat 243 not only adheres to the outer wall of the workpiece through the anti-slip layer 246 of the clamping member 241, but also adheres to the inner wall of the perforation through the lower part of the airbag 247 that is squeezed and inflated by the squeezing member 248. This greatly increases the contact area between the clamping device 24 and the inner and outer walls of the workpiece when clamping it. This enables the clamping member 241 to clamp and transport the workpiece with high stability. Furthermore, the flexible and high-friction airbag 247 and the anti-slip layer 246 respectively contact the inner and outer walls of the workpiece without causing wear to the inner and outer walls of the workpiece, and there is no risk of excessive squeezing causing damage to the workpiece.

[0053] To achieve flexible contact between the extrusion member 248 and the airbag 247, the extrusion member 248 is a laterally extending plate. The opposing sides of the two extrusion members 248 are recessed to form extrusion portions 2481 that correspondingly fit the upper outer wall of the airbag 247. Both extrusion portions 2481 are provided with a flexible layer, specifically, the flexible layer can be made of flexible rubber or other materials. This flexible layer prevents damage to the airbag 247 when the extrusion member 248 compresses the airbag 247 through the extrusion portions 2481, thus avoiding a decrease in the airbag 247's lifespan, and simultaneously improves the stability of the extrusion member 248 compressing the airbag 247.

[0054] Specifically, the upper driving member 23 and the lower driving member 22 are arranged vertically and parallel to each other. A lifting seat 25 is provided between the upper driving member 23 and the lower driving member 22. One end of the lifting seat 25 extends laterally to form a sliding sleeve 251 for laterally sliding insertion of the upper driving member 23, and the other end is folded downward and slidably connected to the top of the lower driving member 22. The lifting driving device is located on the top of the lower driving member 22 and is used to drive the lifting seat 25 to move up and down. The telescopic driving device is located inside the sliding sleeve 251 and is used to drive the upper driving member 23 to move laterally.

[0055] To improve the structural stability of the upper drive member 23 and the lower drive member 22, the mobile drive device 3 further includes a base 33 for rotatably mounting the rotating seat 32. The bottom center of the lower drive member 22 is supported on the base 33 by a support roller 221. The top center is provided with a support cylinder 222 that is vertically coaxial with the support roller 221. The bottom center of the lower drive member 22 is provided with a sleeve 231 that extends vertically and slides 251 on the outside of the support cylinder 222. The support cylinder 222 is provided with a support spring that is positioned at both ends between the sliding sleeve 251 and the lower drive member 22. By adding the support roller 221, support is provided for the middle part of the lower drive member 22, improving the structural stability of the lower drive member 22. Simultaneously, the support column and support cylinder 222, vertically coaxially arranged with the support roller 221 and the upper and lower sliding sleeves 251, along with the support spring sleeved between them and with its upper and lower ends pressing against the sliding sleeve 251 and the lower drive member 22, achieve the effect of the support roller 221 and support spring coaxially supporting the sliding sleeve 251, thereby improving the structural stability of the sliding sleeve 251 and the upper drive member 23. Furthermore, the stability of the moving seat 21 and clamping member 241 when the lower driving member 22 and the upper driving member 23 move together along the transfer guide rail 1 is improved. Moreover, when the lifting seat 25 rises and the clamping member 241 of the upper driving member 23 is suspended and clamping the workpiece, the supporting roller 221 and the supporting spring can still achieve the effect of supporting the sliding sleeve 251 coaxially. Therefore, by adding the supporting roller 221 and the supporting spring, the support strength of the upper driving member 23 and the lower driving member 22 is improved in all aspects, the structural stability of the two is improved, and thus the stability of workpiece handling is improved.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

When the upper drive member (23) moves to the point where the airbag (247) extends into the perforation of the workpiece and the two clamping members (241) correspond to the outer wall of the workpiece, the clamping drive device (242) drives the two clamping members (241) to clamp the outer wall of the workpiece. The two extrusion members (248) move towards each other to extrude the upper part of the airbag (247) so that the lower part of the airbag (247) bulges up and sticks to the inner wall of the perforation.

7. A handling mechanism for a workpiece transfer device as described in claim 6, characterized in that, The extrusion member (248) is a plate extending laterally. The opposing sides of the two extrusion members (248) are recessed to form an extrusion part (2481) that is adapted to the upper outer wall of the airbag (247). Both extrusion parts (2481) are provided with a flexible layer.

8. A handling mechanism for a workpiece transfer device as described in claim 2, characterized in that, The upper drive member (23) and the lower drive member (22) are arranged vertically and parallel to each other. A lifting seat (25) is provided between the upper drive member (23) and the lower drive member (22). One end of the lifting seat (25) extends laterally to form a sliding sleeve (251) for laterally sliding insertion of the upper drive member (23), and the other end is folded down and slidably connected to the top of the lower drive member (22). The lifting drive device is located on the top of the lower drive member (22) and is used to drive the lifting seat (25) to move up and down. The telescopic drive device is located inside the sliding sleeve (251) and is used to drive the upper drive member (23) to move laterally.

9. A handling mechanism for a workpiece transfer device as described in claim 8, characterized in that, The mobile drive device (3) further includes a base (33) for rotatably mounting the rotating seat (32). The bottom center of the lower drive member (22) is supported on the base (33) by a support roller (221). The top center is provided with a support cylinder (222) that is vertically coaxial with the support roller (221). The bottom center of the lower drive member (22) is provided with a sleeve (231) that extends vertically and slides up and down (251) on the outside of the support cylinder (222). The support cylinder (222) is provided with a support spring that is positioned at both ends between the sliding sleeve (251) and the lower drive member (22).
