Description

Technical Field

[0001] The present invention relates to the field of cables, and in particular to a production device and a production method of an aluminum single plate. Background Art

[0002] The production process of aluminum veneer generally includes processes such as unrolling, cutting, bending, welding, fitting, cleaning, spraying and baking. In the fitting process, aluminum veneer with a width of more than 1.2m usually needs to be installed with back ribs. The number and spacing of the back ribs installed will vary with the specifications of the aluminum veneer. The back ribs are generally fixed to the aluminum veneer through a rivet gun. The process is mainly as follows: first, the back rib is placed on the back of the aluminum veneer and temporarily fixed manually. Then, the top of the rivet is placed on the chuck of the rivet gun and the rivet is fixed through the chuck. After completion, the rivet gun is moved to align the bottom of the rivet with the hole of the back rib so that the bottom of the rivet passes through the hole and contacts with the back of the aluminum veneer. Finally, downward pressure is applied to the rivet gun through external force so that the electrode of the rivet gun contacts the back rib or the aluminum veneer to form a current loop, thereby completing the rivet welding process. The above welding process is currently completed manually. Each aluminum plate requires multiple back ribs, and each back rib needs to be fixed by welding with rivets. During each welding, the rivet gun needs to manually apply downward force to the rivet gun to move the electrode of the rivet gun downward. The force that forces the electrode of the rivet gun to move downward is relatively large, which will cause a huge consumption of physical strength for the batch production of aluminum veneers. Therefore, long-term use of the rivet gun will reduce production efficiency due to manual physical consumption. Summary of the invention

At this time, the top of the welding nail located on the placement part is also located below the chuck of the welding nail gun. After the adjustment is completed, the moving plate is driven to move by the sliding part, thereby driving the support plate to move until the welding nail on the support plate is located directly below the corresponding welding nail gun. Then, the second telescopic cylinder drives the support plate to move upward, so that the top of the welding nail enters the chuck of the welding nail gun and is clamped by the chuck of the welding nail gun. At this time, the second telescopic cylinder drives the support plate to move upward, so that the top of the welding nail enters the chuck of the welding nail gun and is clamped by the chuck of the welding nail gun. The two telescopic cylinders and the sliding part make the supporting plate move away from the rivet gun and eventually move to the top of the rivet gun. Finally, the position of the top plate is adjusted by the robot. When the rivet gun is located directly above the welding position of the corresponding back rib, the first telescopic cylinder drives the top plate to move downward, so that the bottom of the rivet passes through the hole on the back rib and contacts the back of the aluminum veneer. Then the first telescopic cylinder continues to apply downward pressure to the rivet gun, so that the electrode of the rivet gun contacts the back rib or the aluminum veneer to form a current loop, thereby completing the welding of the first rivet on all the back ribs of the aluminum veneer. Then the above operation is repeated until the welding of all the rivets on the back rib is completed. Through this device, after the bottom of the rivet contacts the back of the aluminum veneer, there is no need to manually apply downward pressure to the rivet gun. Therefore, no physical effort is required for this step, thereby effectively improving production efficiency in the batch production process of aluminum veneers. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] A robot and a connecting plate 13 provided on the output shaft at the end of the robot;

[0073] A first telescopic cylinder 14 provided on the connecting plate 13 and a top plate 1 provided on the output shaft of the first telescopic cylinder 14;

[0074] A plurality of synchronous shafts 2 are arranged side by side on the top plate 1, the distances between adjacent synchronous shafts 2 are equal, and a spot welding area is formed between the plurality of synchronous shafts 2;

[0075] A nail welding gun 22 is arranged at the bottom of the synchronous shaft 2, and the nail welding guns 22 on each synchronous shaft 2 are located in the same horizontal plane;

[0076] The movable plates 16 are arranged on both sides of the spot welding area, and the ends of the movable plates 16 are slidably connected with the first slide grooves 15 arranged on the surface of the top plate 1;

[0077] A sliding portion for driving the moving plate 16 to slide along the first sliding groove 15;

[0078] A second telescopic cylinder 20 is arranged on the movable plate 16, and a supporting plate 21 is fixedly connected to the output shaft of the second telescopic cylinder 20. The upper surface of the supporting plate 21 is provided with at least one placement surface, and a placement portion for placing welding nails corresponding to the synchronous shaft 2 is provided in the placement surface. When the placement surface is located directly below the synchronous shaft 2, the placement portion is located directly below the corresponding welding nail gun 22.

[0079] In this embodiment, the flattening machine, punching machine, bending machine, welding gun, material washing tank, spraying workshop, high temperature furnace, etc. are all existing technologies (not shown in the figure), and will not be described in detail here. The specific production steps of the aluminum veneer are as follows:

[0080] Step 1: The aluminum coil is cut into aluminum plates of corresponding sizes by a flattening machine;

[0081] Step 2: Use a punch press to cut the aluminum sheet and remove excess waste to form a bendable aluminum sheet;

[0082] Step 3: Bend the bendable aluminum plate at the corresponding position by a bending machine to form a bent aluminum plate;

[0083] Step 4: Use a welding gun to weld the fold of the bent aluminum plate;

[0084] Step 5: Install the angle bracket on the outside of the bent aluminum plate formed in step 4, and install the back reinforcement on the back of the bent aluminum plate through the installation mechanism;

[0085] Step 6: Transfer the bent aluminum plate formed in step 5 to the washing tank for acid washing and alkali washing, remove the surface dirt and then dry it;

[0086] Step 7: Transfer the bent aluminum plate formed in step 6 to the spraying workshop to spray the surface material. After completion, transfer it to a high-temperature furnace and bake it for 25 minutes to 30 minutes before taking it out of the furnace to complete the production of the aluminum veneer.

[0087] For different types of aluminum veneers, the number of back ribs that need to be installed and the intervals between the back ribs will also be different. Therefore, different installation mechanisms are required to adapt to different types of aluminum veneers. Before the production of aluminum veneers, the installation mechanism corresponding to the model of the aluminum veneer is placed on one side of a workbench. This workbench is used to place the aluminum veneer. When the production process of the aluminum veneer reaches the step of installing the back ribs, the aluminum veneer is placed on the workbench, and multiple back ribs are placed on the back of the aluminum veneer at a certain interval. Here, one back rib corresponds to one synchronous axis 2, and then the welding nails are placed on each placement part in turn. After completion, The position of the supporting plate 21 is adjusted by the second telescopic cylinder 20 so that the supporting plate 21 is located at a distance below the end of the welding nail gun 22. At this time, the top of the welding nail on the placement portion is also located below the clamp of the welding nail gun 22. After the adjustment is completed, the movable plate 16 is driven to move by the sliding portion, thereby driving the supporting plate 21 to move until the welding nail on the supporting plate 21 is located directly below the corresponding welding nail gun 22. Then, the second telescopic cylinder 20 drives the supporting plate 21 to move upward, so that the top of the welding nail enters the clamp of the welding nail gun 22 and is clamped by the clamp of the welding nail gun 22. At this time, the supporting plate 21 is driven downward by the second telescopic cylinder 20. During the downward movement of the supporting plate 21, since the welding nails are clamped by the chuck of the welding nail gun 22, the welding nails will be separated from the placement part. After the welding nails are completely separated from the placement part, the second telescopic cylinder 20 stops driving, and then the sliding part starts to drive the supporting plate 21 away from the welding nail gun 22 through the moving plate 16, and finally staggered with the welding nail gun 22. After completion, the second telescopic cylinder 20 drives the supporting plate 21 again, and finally moves to the top of the welding nail gun 22. Finally, the position of the top plate 1 is adjusted by the robot. When the welding nail gun 22 is located just above the welding position of the corresponding back rib, the first telescopic cylinder 14 drives the top plate 1 to move downward, so that The bottom of the rivet passes through the hole on the back rib and contacts the back of the aluminum veneer, and then the first telescopic cylinder 14 continues to apply downward pressure to the rivet gun 22, so that the electrode of the rivet gun 22 contacts the back rib or the aluminum veneer to form a current loop, thereby completing the welding of the first rivet on all the back ribs of the aluminum veneer, and then repeating the above operation until the welding of all the rivets on the back rib is completed. Through this device, after the bottom of the rivet contacts the back of the aluminum veneer, there is no need to manually apply downward pressure to the rivet gun 22, so there is no need to consume physical strength for this step, and thus in the batch production process of aluminum veneers, the production efficiency can be effectively improved.

[0088] Considering that for some different types of aluminum veneers, the number of back ribs required will be the same, and the difference is the distance between the back ribs. Therefore, in order to better adapt the installation mechanism to this situation and enhance the versatility of the installation mechanism, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the installation mechanism also includes a driving part, the synchronization shaft 2 passes through the first adjustment groove 8 provided on the top plate 1, and the synchronization shaft 2 is slidably connected with the corresponding first adjustment groove 8, and the driving part is used to drive each synchronization shaft 2 to slide synchronously along the corresponding first adjustment groove 8, and the angles between the first adjustment grooves 8 and the horizontal plane are not equal, so that when the synchronization shaft 2 slides, the distance between adjacent synchronization shafts 2 is equal.

[0089] In this embodiment, the distance between the synchronous shafts 2 can be adjusted according to the driving unit. When the driving unit drives the synchronous shafts 2, the distance between adjacent synchronous shafts 2 changes synchronously. When the distance between adjacent synchronous shafts 2 is equal to the distance between adjacent back ribs to be installed on the aluminum plate, the driving unit stops driving.

[0090] There are many choices for the structure of the drive unit. Here, we introduce a structure of the drive unit, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the driving unit includes:

[0091] A push-pull rod 5 and a stabilizing plate 6 disposed on the push-pull rod 5, wherein the stabilizing plate 6 is slidably connected to a second sliding groove 7 disposed on the surface of the top plate 1;

[0092] A third telescopic cylinder 3 is arranged on the top plate 1, and an output shaft of the third telescopic cylinder 3 is fixedly connected to the push-pull rod 5;

[0093] The linkage plate 4 is fixedly connected to the top end of the synchronization shaft 2 , and the top of the linkage plate 4 is slidably connected to the third sliding groove 12 arranged on the surface of the push-pull rod 5 .

[0094] In this embodiment, when the third telescopic cylinder 3 drives the push-pull rod 5 to move, since the top of the linkage plate 4 is slidingly connected to the third slide groove 12, the linkage plate 4 can drive each synchronization shaft 2 to move along the corresponding first adjustment groove 8, and the distance between adjacent synchronization shafts 2 can be changed in the above manner.

[0095] As an implementation method, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the sliding part includes a first motor 17 disposed on the top plate 1 and a first screw 18 having one end fixedly connected to the output shaft of the first motor 17 , and the first screw 18 is threadedly connected to a first screw hole 19 disposed on the moving plate 16 .

[0096] In this embodiment, when the first motor 17 is started, it drives the first screw 18 to rotate, thereby driving the movable plate 16 to slide along the first slide groove 15. When the movable plate 16 moves, the second telescopic cylinder 20 can drive the supporting plate 21 to follow the movement of the movable plate 16.

[0097] As an implementation method, Figure 1 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 As shown, the placement surface is provided with a first through groove 29 penetrating the upper and lower surfaces of the supporting plate 21, and the side wall of the first through groove 29 is provided with a first side groove 30. The pad diameter of the welding nail is greater than the width of the first through groove 29, so that the welding nail is placed at the edge of the first through groove 29 through its pad. The placement portion includes:

[0098] An outer slide plate 31 whose side is slidably connected to the first side groove 30, the outer slide plate 31 is provided with a second through groove 32 penetrating through the upper and lower surfaces thereof, and a side wall of the second through groove 32 is provided with a second side groove 33;

[0099] The clamping plates 38 are arranged opposite to each other and the inner slide plate 41 is arranged on the side of the clamping plates 38. The inner slide plate 41 is slidably connected with the second side groove 33. A clamping space for clamping the welding pad is formed between the clamping plates 38.

[0100] One end of the first spring 34 is fixed to one side of the clamping plate 38, and the other end of the first spring 34 is fixed to the corresponding end of the second through slot 32;

[0101] A fixing plate 23 located on one side of the synchronous shaft 2 and a connecting column 24 fixedly connected to the outer sliding plate 31, the bottom of the fixing plate 23 is fixedly connected to the connecting column 24, a surface groove 26 is provided on the side of the fixing plate 23 facing the synchronous shaft 2, the surface groove 26 runs through the front and rear sides of the fixing plate 23, and an inner groove 25 is provided on the side wall of the surface groove 26 facing the synchronous shaft 2, and the width of the inner groove 25 is greater than the width of the surface groove 26;

[0102] The inner plate 27 is slidably connected to the inner groove 25 and the follower rod 28 connects the inner plate 27 and the synchronous shaft 2, the width of the inner plate 27 is greater than the width of the surface groove 26, and the width of the inner groove 25 is greater than the width of the inner plate 27, and the width of the surface groove 26 is greater than the width of the follower rod 28, so that when the second telescopic cylinder 20 adjusts the position of the supporting plate 21, the inner plate 27 and the fixed plate 23 will not interfere in the vertical direction.

[0103] When welding studs by manually holding a stud gun 22, first place the top of the stud in the chuck of the stud gun 22 and clamp it. Then, the bottom of the stud contacts the back of the aluminum plate. After the electrode of the stud gun 22 contacts the aluminum plate or the back rib, start the switch on the stud gun 22. At this time, a high-current circuit is formed to weld the studs, thereby fixing the back rib. It should be noted that in the above process, the switch on the stud gun 22 that forms the circuit is in a closed state only during welding. At other times, it is in a normally open state to prevent accidental touch, which causes the chuck and electrode of the stud gun 22 to form a circuit and cause an accident. In the present device, there are multiple nail welding guns 22 in the installation mechanism. If the switches of the nail welding guns 22 are closed one by one during welding, the efficiency will be reduced. Therefore, in the present device, the switch of the nail welding gun 22 is in a normally closed state. As long as the clamp of the nail welding gun 22 and the electrode can form a circuit that allows current to pass, welding can be completed. Therefore, here, considering the safety issue, the nail cannot be directly fixed to the clamp of the nail welding gun 22 manually, but the nail welding gun 22 is first placed on the placement part to ensure safety. The main process is as follows: when the support plate 21 is away from the nail welding gun 22, the clamp plate 38 is first manually opened, and then the nail is placed on the upper edge of the first through groove 29, and the nail is supported by the welding pad of the nail, and then Loosen the clamping plate 38, under the action of the first spring 34, the clamping plate 38 can be used to clamp the welding plate. When the supporting plate 21 moves the welding nail to the corresponding nail gun 22 through the sliding part and the second telescopic cylinder 20, the second telescopic cylinder 20 immediately moves the supporting plate 21 upward, so that the top of the welding nail enters the clamp of the nail gun 22, so that the welding nail is clamped by the clamp of the nail gun 22, and then the second telescopic cylinder 20 moves downward again, so that the welding nail overcomes the clamping force of the clamping plate 38 and finally leaves the clamping space. After completion, the supporting plate 21 is restored to its original position again through the sliding part and the second telescopic cylinder 20. In this process, the safety problem of placing the welding nail directly on the nail gun 22 by manual operation is avoided. In addition, here, a fixed plate 23, an inner plate 27 and a follower rod 28 are also provided, so that when the synchronous shaft 2 moves along the first adjustment groove 8, the outer slide plate 31 is driven to move synchronously through the fixed plate 23 to ensure that the relative position of the synchronous shaft 2 and the clamping space remains unchanged.

[0104] Here, further improvements have been made to the placement part, such as Figure 1 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 As shown, the placement unit also includes:

[0105] The electromagnets 42 are arranged in the inner slides 41, between the inner slides 41 opposite to each other, and between the two electromagnets 42, are used to generate a mutual repulsive force after being energized;

[0106] A balancing block 43 having one end slidably connected to a balancing groove 44 provided on the opposite side of the clamping plate 38, a portion of the balancing block 43 extends into the clamping space, and the balancing block 43 is located above the supporting plate 21;

[0107] One end of the second spring 45 is fixedly connected to the bottom of the balancing groove 44 , and the other end of the second spring 45 is fixed to the balancing block 43 .

[0108] In this embodiment, without the above-mentioned improvements, the realization of the placement function will not be affected. With the above-mentioned improvements, the work efficiency can be further improved. Specifically, before placing the welding nail, the electromagnet 42 is energized to generate a mutually repelling force, so that the clamping plates 38 are separated from each other. After separation, the balance block 43 is manually lifted up by one end, and then the welding pad of the welding nail is located below the balance block 43. Then the electromagnet 42 is de-energized. Under the action of the first spring 34, the clamping plate 38 will clamp the welding pad. At this time, the external force applied to the balance block 43 is removed, so that the balance block 43 will be under the action of the second spring 45. A downward external force is applied to the welding pad to ensure that the welding pad does not tilt. The reason why the welding pad may tilt is that when the welding nail is manually placed on the upper edge of the first through slot 29, it may shake. If the clamping plate 38 starts to clamp during the shaking, it may cause the welding pad to tilt after clamping. If tilting occurs, the top of the welding nail may not be aligned with the clamping head of the welding nail gun 22. After the clamping head of the welding nail gun 22 is aligned with the top of the welding nail and clamps the welding nail, the electromagnet 42 is energized to separate the clamping plates 38 from each other, and at the same time separate the balance block 43 from the welding pad, and then the support plate 21 can be restored to its original position.

[0109] Of course, if the balancing blocks 43 are lifted one by one manually, the workload will be quite large. Therefore, the mounting mechanism is further improved here, such as Figure 1 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 As shown, the mounting mechanism also includes:

[0110] A through rod 39 slidably connected to a through hole 40 provided at the bottom of the clamping plate 38, the through hole 40 is communicated with the balancing groove 44, and one end of the through rod 39 is fixedly connected to the balancing block 43, and a second spring 45 is sleeved on the outside of the through rod 39;

[0111] The bottom rod 35 is located below the supporting plate 21 , and a bottom slide groove is provided on the side surface of the bottom rod 35 , and the other end of the through rod 39 is slidably connected to the bottom slide groove.

[0112] Relative to the limiting plates 37 disposed on the lower surface of the supporting plate 21 , a limiting space is formed between the two limiting plates 37 , and the bottom rod 35 is located in the limiting space.

[0113] Here, the lifting operation of the balancing block 43 can be completed by directly applying an upward external force to the bottom rod 35, and the above operation can be completed for the balancing blocks 43 in multiple placement parts at one time, thereby improving work efficiency.

[0114] In addition, considering that the back reinforcement generally requires multiple rivets for fixing, if there is only one placement surface, then after the welding of all the back reinforcements on the aluminum veneer is completed once, it is necessary to manually repeat the operation of placing the rivets for a short time. In this way, only when the aluminum veneer is mass-produced, one installation mechanism can be selected to install the back reinforcement, which effectively improves the efficiency. Therefore, in this embodiment, if Figure 1 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.15 , Fig.16 As shown, there are multiple placement surfaces, and the first through grooves 29 in the placement surfaces are parallel to each other. The number of placement surfaces is preferably equal to the number of welding nails required for one back rib. When mass-producing aluminum veneers, two installation mechanisms can be selected to install the back ribs. For example, two aluminum veneers are placed on a workbench, and both aluminum veneers are located on one side of the installation mechanism. After the staff places all the welding nails on the corresponding positions of the support plate 21, the installation mechanism can perform the welding operation of the welding nails. At this time, after the installation mechanism has welded all the welding nails on one of the placement surfaces, the sliding part and the second telescopic cylinder 20 can drive the other placement surface to the welding nail gun 22. , so that the welding nails on the placement surface are facing the corresponding welding nail gun 22. At the same time, the robot adjusts the position of the top plate 1 so that this side moves to the top of the next welding position of the back reinforcement for welding. Repeat the above steps until the installation mechanism completes the welding operation. During the welding process of the installation mechanism, the staff can go to another installation mechanism and place the welding nails at the corresponding positions of the supporting plate 21 of the installation mechanism. After completion, the welding of the previous installation mechanism is just completed, and then an aluminum single plate can be placed on one side of the installation mechanism, and the welding nails are placed at the corresponding positions of the supporting plate 21. Repeat the above operations, which can greatly improve production efficiency.

[0115] As an implementation method, Figure 1 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown, the mounting mechanism also includes:

[0116] A crossbeam 48 is located at one side of the spot welding area, and a second adjustment groove 49 is provided on the lower surface of the crossbeam 48;

[0117] A fourth telescopic cylinder 47 is provided on the lower surface of the top plate 1, and an output shaft of the fourth telescopic cylinder 47 is fixedly connected to the crossbeam 48;

[0118] A transition rod 52 corresponding to the synchronization shaft 2, the top end of the transition rod 52 being slidably connected to the second adjustment groove 49;

[0119] A connecting rod 10 with a sliding hole 53 at the top, and a bottom of a transition rod 52 is slidably connected to the sliding hole 53;

[0120] A third spring 9 is located in the sliding hole 53, one end of the third spring 9 is fixedly connected to the bottom of the sliding hole 53, and the other end of the third spring 9 is fixedly connected to the bottom end of the transition rod 52;

[0121] A clamp 11 is provided at the bottom of the connecting rod 10, and the clamp 11 is used to clamp the back tendon;

[0122] A second motor 46 is provided at one end of the crossbeam 48 and a drive shaft 50 having one end fixedly connected to the output shaft of the second motor 46, the drive shaft 50 passes through an axial hole 51 provided on the transition rod 52, and the side surface of the drive shaft 50 is divided into a plurality of drive areas, and the drive areas correspond to the transition rods 52 one by one. Active drive patterns distributed on the side surfaces of the drive shaft 50 are provided in the drive areas, and passive drive patterns matching the corresponding active drive patterns are provided on the inner wall of the axial hole 51, so that when the synchronous shaft 2 slides along the first adjustment groove, the drive shaft 50 rotates synchronously, and the active drive patterns cooperate with the corresponding passive drive patterns, so that the sliding speed of the transition rod 52 along the second adjustment groove 49 is synchronized with the movement speed of the synchronous shaft 2 in the direction of the third slide groove 12.

[0123] Since the back reinforcement is directly placed on the back side of the aluminum veneer, the distance between the back reinforcements is difficult to control accurately. Therefore, in this embodiment, one end of the back reinforcement is directly clamped by the clamp 11. When the clamp of the rivet gun 22 clamps the top of the rivet, the robot adjusts the position of the top plate 1 so that the top plate 1 is located above the aluminum veneer. Then the first telescopic cylinder 14 drives the top plate 1 to move downward. The back reinforcement first contacts the back side of the aluminum veneer, and then the third spring 9 is compressed. After the first rivet of the back reinforcement is welded, the clamp 11 releases the back reinforcement, and through the fourth telescopic cylinder 47, the clamp 11 moves upward for a distance to ensure that the clamp 11 will not touch the back reinforcement during the subsequent back reinforcement welding process. After all the rivets are welded, the fourth telescopic cylinder 47 moves the clamp 11 downward for a distance until the next time the back reinforcement is clamped. The clamp 11 here can realize automatic clamping, which is a commonly used clamping component and will not be described here. When the synchronization shaft 2 moves along the first adjustment groove 12 , the second motor 46 is started, and the relative distance between the synchronization shaft 2 and the transition rod 52 is kept constant through the drive shaft 50 . It should be noted here that, since the synchronous shaft 2 is provided with a plurality of active drive lines and passive drive lines, it is first assumed that the synchronous shaft 2 is provided with an even number of lines, for example, 4 lines, then two of the first adjustment grooves 12 on the top plate and the other two first adjustment grooves 12 are symmetrically arranged, and the four first adjustment grooves are all inclinedly arranged, so that the active drive lines and the passive drive lines are both threads, but the helix angles and pitches of the threads in different drive areas are different, so that when the drive shaft 50 rotates, the speed between the transition rod 52 and the synchronous shaft 2 in the horizontal direction is the same, and it is assumed that the synchronous shaft 2 is provided with an odd number of lines, for example, 5 lines, then the first adjustment groove 12 located in the middle will be vertical, so that the active drive lines and the passive drive lines in the drive areas on both sides of the middle drive area are consistent with the above, and are all threads, the active drive lines in the middle drive area are a plurality of mutually parallel annular grooves, and the corresponding passive drive lines are convex rings arranged inside the corresponding shaft holes, the convex rings are adapted to the annular grooves, and the convex rings are located inside the annular grooves, so as to ensure that the corresponding transition rod 52 does not change its position when the drive shaft 50 rotates.
