Description

Technical Field

[0001] The invention belongs to the technical field of wire processing equipment, and in particular relates to a multi-station automatic casing machine. Background Art

[0002] Wires refer to conductors that transmit electrical energy. After the wires are produced, a sleeve machine can be used to sleeve short hoses made of PVC, TPU and other materials on the ends of the wires. After workers label the short hoses, they can clearly distinguish the types and models of the wires, avoiding confusion during packaging and use.

[0003] Existing tubing machines mainly consist of a tube feeding mechanism, a tube cutting mechanism, and an assembly mechanism. The tube feeding mechanism is used to transport the entire long hose to the tube cutting mechanism. The tube cutting mechanism cuts the long hose into short hoses, and then the assembly mechanism transfers the short hoses and sleeves them onto the wires to complete the assembly. This is relatively convenient to use. However, in actual use, it is found that the existing tubing machines still have at least the following defects: First, the tube delivery mechanism can only deliver long hoses of a single diameter to the tube cutting mechanism for cutting, and the assembly mechanism can only put short hoses of a single diameter onto the appropriate wires, resulting in poor applicability of the overall equipment.

[0004] Secondly, the assembly mechanism needs to wait for the tube cutting mechanism to cut out a short hose before it can transfer the corresponding short hose to the wire for installation. That is, the tube cutting operation and the assembly operation cannot be carried out simultaneously, which affects the assembly speed and leads to low working efficiency of the overall equipment.

[0005] In view of this, it is necessary to design a multi-station automatic casing machine to solve this problem. Summary of the Invention

DETAILED DESCRIPTION

It will be understood that the drawings are only provided for reference and illustration purposes and are not intended to limit the present invention. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0022] See attached Figure 1 -Attached Figure 17 , a multi-station automatic casing machine includes a machine body 1, a pipe feeding mechanism 2, a pipe cutting mechanism 3 and an assembly mechanism 4; the pipe feeding mechanism 2 includes a carrier 21, a feeding part 22 and a lifting unit 23; the carrier 21 is provided with a placement plate 211 with a work station hole 2110 and a guide plate 212 with a guide hole 2120, the work station hole 2110 is provided with a plurality of and vertically arrayed, and the guide holes 2120 are provided with a plurality of and aligned one by one with the plurality of work station holes 2110; the feeding part 22 is mounted on the machine body 1 and is located beside the guide plate 212; the lifting unit 23 is mounted on the machine body 1 and is used to drive the carrier 21 to move in the vertical direction so that the plurality of guide holes 2120 are aligned one by one with the feeding part 22; the pipe cutting mechanism 3 is mounted on the machine body 1 and is located beside the feeding part 22; the assembly mechanism 4 includes a turntable 41, an assembling part 42 and a rotating unit 43, the turntable 41 is located beside the pipe cutting mechanism 3, and the turntable 41 is symmetrical on the same straight line Two material levels 410 are provided; the assembly part 42 is installed on the body 1 and is located next to the turntable 41; the rotating unit 43 is installed on the body 1 and is used to drive the turntable 41 to rotate, and when one material level 410 is aligned with the tube cutting mechanism 3, the other material level 410 is synchronously aligned with the assembly part 42; wherein, each work station hole 2110 can be provided with at least one type of long hose R1 of pipe diameter, and each guide hole 2120 can be provided to guide the corresponding long hose R1 to the feeding part 22, and both material levels 410 can fix long hoses R1 of the same pipe diameter; the feeding part 22 is used to transport the long hose R1 to the material level 410 aligned with the tube cutting mechanism 3, and the tube cutting mechanism 3 is used to cut the long hose R1 and form a short hose R2 at the material level 410, and the turntable 41 rotates to align the material level 410 with the assembly part 42, and the assembly part 42 is used to transfer the short hose R2 and put it on the wire (not shown in the figure) to complete the assembly.

[0023] Specifically, before use, workers can preset and adjust multiple workstation holes 2110 and multiple guide holes 2120 according to actual needs to respectively pass through and place long hoses R1 of different diameters.

[0024] During use, the wires are placed beside the assembly part 42. When the work station hole 2110 with the corresponding long hose R1 and the corresponding guide hole 2120 are aligned with the feeding part 22, the long hose R1 of the current diameter model can be accurately guided to the feeding part 22, and the long hose R1 is transported to a material level 410 by the feeding part 22. After the tube cutting mechanism 3 cuts the long hose R1 and forms a short hose R2 at the material level 410, the rotating unit 43 is started to drive the turntable 41 to rotate, so that the material level 410 with the short hose R2 is aligned with the assembly part 42, so that the short hose R2 is transferred by the assembly part 42 and put on the wire to complete the assembly, and the other vacant material level 410 is synchronously transferred and aligned with the feeding part 22 to facilitate the continued placement of the new short hose R2.

[0025] When it is necessary to assemble short hoses R2 of other diameters, first close the feeding part 22, the tube cutting mechanism 3, and the assembly mechanism 4, and then drive the carrier 21 up and down through the lifting unit 23 to align the workstation holes 2110 and the guide holes 2120 where other long hoses R1 of different diameters are placed with the feeding part 22 one by one to complete the workstation switching. After the required long hose R1 is aligned with the feeding part 22, start the feeding part 22, the tube cutting mechanism 3 and the assembly mechanism 4, and continue to cut the long hose R1 of the corresponding diameter according to the above operation method, and transfer and put the short hose R2 of the corresponding diameter onto the corresponding wire.

[0026] In summary, the present invention provides the workstation holes 2110 and the guide holes 2120 on the placement plate 211 and the guide plate 212 of the tube feeding mechanism 2 for inserting, placing and accurately guiding the long hose R1 to the feeding part 22, thereby preventing the long hose R1 from collapsing. Since there are multiple workstation holes 2110 and guide holes 2120, long hoses R1 of various diameters can be inserted, placed and guided. Moreover, the lifting unit 23 is installed on the machine body 1 to control the movement of the carrier 21 in the vertical direction to complete the workstation switching, so that the long hoses R1 of different diameters can be aligned with the feeding part 22 one by one, ensuring that the feeding part 22 can transport long hoses R1 of various diameters. Two symmetrical material positions 410 are provided on the turntable 41 of the assembly mechanism 4, so that one When the material level 410 with the short hose R2 is aligned with the assembly part 42 for assembly, another empty material level 410 can be synchronously aligned with the tube cutting mechanism 3 to place a new short hose R2, ensuring that the loading and assembly of the short hose R2 are carried out synchronously; therefore, compared with the existing technology, this multi-station automatic sleeve machine can not only transport and cut long hoses R1 of various diameters, thereby improving the applicability of the overall equipment, but also can synchronously complete the assembly of short hoses R2 of corresponding diameters during the process of cutting the long hose R1, thereby improving the work efficiency of the overall equipment; on the other hand, the vertical array of multiple station holes 2110 and multiple guide holes 2120 can also support the volume of the carrier 21, and the unique structural design of the turntable 41 makes the overall equipment more compact, effectively reducing space occupancy.

[0027] See attached Figure 3 -Attached Figure 10 There are many types of feeding parts 22 on the market, so the present invention does not limit this. For the convenience of understanding, in this embodiment, the feeding part 22 includes a pillar 221, a swing arm 222, a pipe wheel 223, a first driving member 224 and a second driving member 225; the pillar 221 is vertically mounted on the body 1 and is rotatably connected to the swing arm 222, the pipe wheel 223 is rotatably mounted on the first end of the swing arm 222 and is located next to the guide plate 212; the first driving member 224 is mounted on the body 1 and is drivingly connected to the second end of the swing arm 222, The swing arm 222 is driven to swing or stop, thereby causing the wheel 223 to move away from or approach the guide hole 2120; the second driving member 225 is installed on the body 1 and is drivingly connected to the wheel 223 to drive the wheel 223 to rotate; wherein, the feeding part 22 is provided with two groups and is symmetrically arranged on the left and right sides of the guide plate 212, and the two first driving members 224 can synchronously drive the two swing arms 222 to swing so that the two wheel 223 synchronously abut or release the long hose R1, and any group of feeding parts 22 may not be provided with the second driving member 225.

[0028] Specifically, under normal circumstances, the second driving member 225 is in a closed state, and the two first driving members 224 drive the two swing arms 222 to swing synchronously so that the two pipe wheels 223 expand each other and move away from the guide plate 212; when it is necessary to transport the long hose R1, the lifting unit 23 controls the carrier 21 to move in the vertical direction so that the long hose R1 of the corresponding diameter enters the middle of the two pipe wheels 223, and then the two first driving members 224 are activated to drive the two swing arms 222 to swing synchronously so that the two pipe wheels 223 move closer to each other and abut the long hose R1. After the two swing arms 222 are stopped by the movable member 224, the second driving member 225 is activated to rotate the corresponding pipe wheel 223, thereby moving the long hose R1 to the next process. After the long hose R1 of the current diameter is conveyed, if it is necessary to switch the workstation to convey the long hose R1 of a different diameter, the first driving member 224 is again used to drive the two swing arms 222 to swing synchronously, causing the two pipe wheels 223 to expand relative to each other and move away from the guide plate 212. This prevents the feeding section 22 from blocking the long hose R1 from entering between the two pipe wheels 223 during the process of switching workstations.

[0029] In summary, compared with the conventional feeding part 22 in the prior art, the above structural design can ensure that the feeding part 22 can be smoothly used in conjunction with the work station hole 2110 and the guide hole 2120 of the carrier 21, thereby avoiding the feeding part 22 hindering the work station switching, thereby effectively improving work efficiency; wherein, if one second driving member 225 is provided, then one wheel 223 can be driven to rotate alone to drive the long hose R1, and the other wheel 223 is driven by the moving long hose R1; if two second driving members 225 are provided, then the two wheels 223 can be driven synchronously to rotate in opposite directions, thereby synchronously conveying the long hose R1; the manufacturer can vertically adjust the number of second driving members 225 according to actual needs, and there is no restriction on this in this embodiment.

[0030] See attached Figure 5 -Attached Figure 10 The second end of the swing arm 222 is rotatably mounted with a roller 222d, and the first driving member 224 includes a first cylinder 2241, a first connecting rod 2242 and a first slider 2243; the first slider 2243 is slidably mounted on the pillar 221 and fixedly connected to the first connecting rod 2242, and the first slider 2243 is also provided with a wheel groove 224d that rotatably cooperates with the roller 222d; the first cylinder 2241 is mounted on the body 1, and the telescopic end of the first cylinder 2241 is fixedly connected to the first connecting rod 2242.

[0031] Specifically, by controlling the telescopic end of the first cylinder 2241 to extend or contract, the roller 222d and the wheel groove 224d can be driven to rotate relative to each other, thereby driving the first slider 2243 to move back and forth, thereby causing the swing arm 222 to swing. When the telescopic end of the first cylinder 2241 stops extending and retracting, the first slider 2243 stops moving, causing the swing arm 222 to stop.

[0032] See attached Figure 5 -Attached Figure 10 A first shaft 2210 is rotatably mounted inside the pillar 221, the swing arm 222 is rotatably connected to the first shaft 2210, and a second shaft 2220 fixed to the pulley 223 is rotatably mounted on the first end of the swing arm 222, and the second driving member 225 includes a first motor 2251, a belt 2252, a pulley 2253, a main gear 2254 and a sub-gear 2255; the main gear 2254 and the sub-gear 2255 are both movably arranged inside the swing arm 222 and mesh with each other, and the main gear 2254 is coaxially fixed to the head end of the first shaft 2210, and the sub-gear 2255 is coaxially fixed to the second shaft 2220; the pulley 2253 is coaxially fixed to the tail end of the first shaft 2210, the first motor 2251 is mounted on the body 1, and the output end of the first motor 2251 is connected to the pulley 2253 through the belt 2252.

[0033] Specifically, when the first driving member 224 drives the two pipe wheels 223 to synchronously abut the long hose R1, the first motor 2251 is started, and the output end of the first motor 2251 drives the first shaft 2210 to rotate through the belt 2252 and the pulley 2253, thereby driving the main gear 2254 to rotate and drive the sub-gear 2255 to rotate, and the sub-gear 2255 drives the pipe wheels 223 to rotate synchronously through the second shaft 2220 to transport the long hose R1; when the first driving member 224 drives the two swing arms 222 to swing away from the guide When moving toward the plate 212, the main gear 2254 and the sub-gear 2255 will both move with the swing arm 222. During this process, the sub-gear 2255 may rotate slightly and drive the main gear 2254 and the first shaft 2210. Therefore, before starting the first driving member 224, it is necessary to first turn off the first motor 2251 and ensure that the output end of the first motor 2251 can rotate normally, so that the first shaft 2210 has a corresponding amount of rotation to avoid the main gear 2254 and the sub-gear 2255 from being damaged by a rigid collision.

[0034] It should be noted that the first driving member 224 for driving the swing arm 222 to swing and the second driving member 225 for driving the pipe wheel 223 to rotate have various related structures, which are not listed or limited in the present invention.

[0035] See attached Figure 10 , anti-skid grooves 2230 are provided on the circumferential outer wall of the pipe wheel 223; the design of the anti-skid grooves 2230 can increase the friction between the pipe wheel 223 and the long hose R1, reducing the risk of the long hose R1 detaching.

[0036] See attached Figure 5 -Attached Figure 11The lifting unit 23 is of various types, and the present invention does not limit this. For the convenience of understanding, in this embodiment, the lifting unit 23 includes a second motor 231, a screw 232, a screw block 233 and a support rod 234. The support rod 234 is vertically and slidably mounted on the body 1 and fixedly connected to the carrier 21, the screw block 233 is fixedly connected to the support rod 234, and the screw 232 is vertically and rotatably mounted on the body 1 and threadedly connected to the screw block 233; the second motor 231 is mounted on the body 1, and the output end of the second motor 231 is coaxially fixedly connected to the screw 232, driving the second motor 231 to drive the carrier 21 to move in the vertical direction; starting the second motor 231 drives the screw 232 to rotate, so as to drive the screw block 233 and the support rod 234 to move in the vertical direction, thereby causing the carrier 21 to move in the vertical direction to complete the workstation switching.

[0037] See attached Figure 3 -Attached Figure 13 The manufacturer can set the apertures of the multiple station holes 2110 to be various so as to adapt and fix the long hoses R1 of different diameters. However, this will reduce the adaptability of the single station hole 2110 and the restriction ability of the long hose R1 is weak, resulting in the possibility of the long hose R1 falling off during the switching of the stations. To solve this problem, the pipe feeding mechanism 2 of the present invention also includes a position adjustment part 5, and the storage plate 211 also has a plurality of through grooves 2111 arranged vertically in an array. The through slots 2111 are connected to the plurality of workstation holes 2110 in a one-to-one correspondence, and a fixed pad 2112 is provided inside the through slots 2111 on the left side of the workstation hole 2110, and a slidable clamping block 2113 is provided inside the through slots 2111 on the right side of the workstation hole 2110; the storage plate 211 also has a plurality of movable slots 2114 arranged in a vertical array, and the plurality of movable slots 2114 are connected to the plurality of through slots 2111 one by one, and a through movable slot is provided on the end of the clamping block 2113 away from the pad 2112 2114 to the outside of the head 21130; the adjustment portion 5 includes a first elastic member 51, a hook head 52 and a third driving member 53, the first elastic member 51 is provided with a plurality of and is arranged one by one in a plurality of movable grooves 2114, and the two ends of the first elastic member 51 respectively abut the clamping block 2113 and the inner wall of the movable groove 2114; the third driving member 53 is installed on the body 1 and is connected to the hook head 52; wherein, the first elastic member 51 can drive the clamping block 2113 along the through groove 2111 It moves inward and abuts the pad 2112, thereby clamping the long hose R1 passing through the work station hole 2110; the lifting unit 23 can drive the carrier 21 to move in the vertical direction so that the abutments 21130 of multiple clamping blocks 2113 are aligned with the hook head 52 one by one, and the third driving member 53 can drive the hook head 52 to apply pressure to the abutment 21130, so as to drive the clamping block 2113 to move outward along the through groove 2111 and squeeze the first elastic member 51, thereby loosening the long hose R1 passing through the work station hole 2110.

[0038] Specifically, under normal circumstances, the clamping block 2113 moves inward along the through slot 2111 under the elastic tendency of the first elastic member 51 to approach the pad 2112 to clamp the long hose R1. When the long hose R1 needs to be transported, the third driving member 53 is controlled to drive the hook head 52 to abut against the abutment 21130. After the hook head 52 applies pressure to the abutment 21130, the clamping block 2113 can be driven to move outward along the through slot 2111 away from the pad 2112 to release the restriction on the long hose R1, thereby facilitating the transportation of the long hose R1. In this process, the outward-moving clamping block 2113 squeezes the first elastic member 51, causing it to deform and store energy. When it is necessary to switch workstations, the third driving member 53 drives the hook head 52 to disengage from the abutment 21130. During this process, the first elastic member 51 releases energy to recover and drives the clamping block 2113 to move inward along the through groove 2111 close to the pad 2112 to fix the remaining long hose R1. Then, the lifting unit 23 drives the carrier 21 to move in the vertical direction so that the other long hoses R1 to be transported are aligned with the feeding part 22. At this time, the hook head 52 corresponds to the abutment 21130 of the new clamping block 2113. The worker repeats the above operation to transport the new long hose R1 to the next process.

[0039] In summary, the design of the first elastic member 51 can drive the clamping block 2113 and the pad 2112 to clamp the long hose R1 just tightly, avoiding excessive squeezing of the long hose R1 and causing it to rupture, and the design of the hook head 52 can align the abutment heads 21130 of multiple clamping blocks 2113 one by one, which can effectively save costs while ensuring that the outward movement of multiple clamping blocks 2113 can be controlled.

[0040] Furthermore, the specifications of the pad 2112 and the clamp 2113 are adjustable. Workers can install pads 2112 and clamps 2113 of corresponding specifications in each work station hole 2110 according to their needs, so that the work station hole 2110 can be more suitable for passing and fixing long hoses R1 of different diameters; and the pad 2112 can be made of rubber, silicone and other materials to give it a certain deformation ability and recovery ability, ensuring that it can stably fit the long hose R1 and reduce the possibility of damage to the long hose R1.

[0041] See attached Figure 3 -Attached Figure 13, the structure of the third driving member 53 is various, and the present invention does not limit this. For the convenience of understanding, in this embodiment, the third driving member 53 includes a column 531, a second cylinder 532, a second connecting rod 533 and a second slider 534; the column 531 is mounted on the machine body 1, and the second slider 534 is slidably mounted on the column 531 and fixed to the hook head 52, and the second slider 534 is also provided with a slot 5341 for a built-in round rod 5342; the head end of the second connecting rod 533 is inserted into the slot 5341 and is provided with a notch 5331 that rotates with the round rod 5342, and the middle part of the second connecting rod 533 is hinged to the column 531; the second cylinder 532 is swingably mounted on the machine body 1 The telescopic end of the second cylinder 532 is controlled to contract, so as to drive the second slider 534 to move away from the carrier 21 through the second connecting rod 533, thereby driving the hook head 52 to abut against the abutment 21130 to apply pressure, and squeeze the first elastic member 51 to deform and store energy; the telescopic end of the second cylinder 532 is controlled to extend, so as to drive the second slider 534 to move toward the carrier 21 through the second connecting rod 533, thereby driving the hook head 52 to break away from the abutment 21130, so that the first elastic member 51 releases energy to recover and drive the clamping block 2113 to move inward along the through groove 2111 to approach the pad 2112.

[0042] See attached Figure 3 -Attached Figure 13 The carrier 21 is also provided with a guide block 214 and a fixing plate 213 with a fixing hole 2130; the guide block 214 is fixedly connected to the carrier 21; the guide plate 212 is located between the storage plate 211 and the feeding part 22, and a guide rail 2121 is horizontally installed on the guide plate 212 in sliding connection with the guide block 214; the fixing plate 213 is installed on the guide rail 2121 and is located between the feeding part 22 and the pipe cutting mechanism 3, and a plurality of fixing holes 2130 are provided and aligned one by one with the plurality of guide holes 2120; moving the guide plate 212 along the length direction of the guide rail 2121 can make the guide hole 2120 move away from or closer to the feeding part 22, and make the fixing hole 2130 move away from or closer to the pipe cutting mechanism 3 synchronously.

[0043] Specifically, the coordinated use of the guide rail 2121 and the guide block 214 facilitates workers to adjust the positional relationship between the placement plate 211 and the guide plate 212 and the feeding part 22, as well as to adjust the positional relationship between the fixing plate 213 and the tube cutting mechanism 3, thereby avoiding the collapse of the suspended portion of the long hose R1, ensuring that the long hose R1 passing through the guide hole 2120 can normally enter the feeding part 22, and ensuring that the long hose R1 conveyed by the feeding part 22 and passing through the fixing hole 2130 can normally enter the tube cutting mechanism 3 and the material level 410 after collapse, thereby improving the conveying stability of the long hose R1.

[0044] Furthermore, in order to achieve electric control and improve the degree of automation, in the present invention, a third cylinder 215 is also installed on the carrier 21, and the telescopic end of the third cylinder 215 is fixedly connected to the guide plate 212 to drive the guide plate 212 to move along the length direction of the guide rail 2121, thereby adjusting the positional relationship between the storage plate 211 and the guide plate 212 and the feeding part 22, and adjusting the positional relationship between the fixed plate 213 and the pipe cutting mechanism 3.

[0045] See attached Figure 5 and attached Figure 13 The work station hole 2110, the guide hole 2120 and the fixing hole 2130 are all equipped with hollow wear-resistant pads 216. The long hose R1 can be passed through the wear-resistant pads 216. The wear-resistant pads 216 are made of silicone, rubber and other materials. This design can reduce the wear of the long hose R1 and extend the service life of the hose R1.

[0046] See attached Figure 1 -Attached Figure 4 , Attachment Figure 14 and attached Figure 19 The pipe cutting mechanism 3 includes a knife seat 31, a cutter 32 and a fourth driving member 33. The knife seat 31 is provided with two and is symmetrically fixed on both sides of the machine body 1. The cutter 32 is provided with two pieces and is slidably installed on the two knife seats 31 one by one. The fourth driving member 33 is installed on the machine body 1 and is synchronously driven and connected with the two cutters 32.

[0047] Specifically, when the feeding part 22 conveys the long hose R1, the fourth driving member 33 drives the two cutters 32 away from each other to allow the long hose R1 to pass; when the long hose R1 enters the material level 410, the fourth driving member 33 drives the two cutters 32 to move closer to each other to cut the long hose R1 and allow the formed short hose R2 to remain in the material level 410; it should be noted that in actual application, the structure of the tube cutting mechanism 3 is diverse and relatively conventional in the mechanical field, so this is not limited in the present invention.

[0048] Furthermore, the structure of the fourth driving member 33 is diverse, and the present invention does not impose any restrictions on this. For ease of understanding, in this embodiment, the fourth driving member 33 includes two fourth cylinders 330, and the two fourth cylinders 330 are fixedly installed on the two knife seats 31 one by one, and the telescopic ends of the two fourth cylinders 330 are respectively fixedly connected to the two cutting knives 32 to drive the two cutting knives 32 to move closer to or away from each other.

[0049] See attached Figure 1 -Attached Figure 4 and attached Figure 14 -Attached Figure 17 There are more than three material levels 410 in the circular array on the turntable 41, and the total number of the material levels 410 is an odd number or an even number.

[0050] Specifically, if there are more than three material levels 410 and the total amount is an odd number, each material level 410 can be used to place a long hose R1 of the same diameter model, which is equivalent to having multiple material levels 410 set at intervals on the turntable 41. In this case, the turntable 41 can store more short hoses R2 cut by the tube cutting mechanism 3, which can shorten the switching time of each material level 410 and improve work efficiency, and ensure that the assembly part 42 can be set at multiple positions of the turntable 41 to transfer the short hoses R2 on the corresponding material level 410, thereby improving the installation convenience of the assembly part 42.

[0051] It should be noted that after replacing the long hose R1 with a different diameter model, each material level 410 needs to be uniformly adjusted to ensure that each material level 410 can be adapted to place the current long hose R1 again.

[0052] If there are more than three material levels 410 and the total amount is an even number, then two material levels 410 located on the same straight line and symmetrically arranged form a storage group, and the storage group has multiple and one-to-one corresponding multiple work station holes 2110; in this case, each storage group of the turntable 41 can correspond to a one-to-one corresponding multiple work station holes 2110, so as to respectively adapt to the placement of long hoses R1 of different diameters, that is, after the worker switches the work station of the carrier 21 through the lifting unit 23, the worker resets the initial position of the turntable 41 through the rotating unit 43, so that the corresponding two material levels 410 are aligned with the pipe cutting mechanism 3 and the assembly part 42, respectively, and the loading and assembly of the long hose R1 of the corresponding diameter can be completed, thereby improving the convenience of use.

[0053] It should be noted that, in actual use, workers can set the corresponding number of material levels 410 on the turntable 41 to meet the usage requirements in different scenarios, and the present invention does not impose any restrictions on this.

[0054] See attached Figure 4 and attached Figure 14 -Attached Figure 16 A fastening block 411 is detachably mounted on the material level 410 , and a sleeve rod 412 is provided on the fastening block 411 ; the feeding portion 22 can transport the long hose R1 to the material level 410 and insert the sleeve rod 412 , and after the tube cutting mechanism 3 cuts the long hose R1 , the short hose R2 is left on the sleeve rod 412 .

[0055] Specifically, if there are two material levels 410 and they are located on the same straight line, or there are more than three material levels 410 in a circular array and the total amount is an odd number, then a sleeve rod 412 with the same diameter needs to be replaced at each material level 410, and the diameter of the sleeve rod 412 needs to be the same as the diameter of the long hose R1 to be transported; if there are more than three material levels 410 in a circular array and the total amount is an even number, then the diameters of the sleeve rods 412 in the same storage group are the same, while the diameters of the sleeve rods 412 in every two storage groups are different, to ensure that the sleeve rods 412 in each storage group can be adapted one by one to be plugged into the long hoses R1 of different diameters in each work station hole 2110; and the fastening block 411 is detachably connected to the turntable 41, which is convenient for workers to replace sleeve rods 412 of different diameters, thereby improving operational convenience.

[0056] It should be noted that the fastening block 411 can be installed on the turntable 41 by screws, or fixed to the turntable 41 by a snap structure or a magnetic structure. Due to the variety of related detachable structures, this is not limited in the present invention.

[0057] See attached Figure 1 -Attached Figure 3 and attached Figure 14 -Attached Figure 16 The assembly mechanism 4 also includes a locking unit 44. The fastening block 411 is further provided with a locking rod 413 with a locking head 4130. The locking unit 44 includes a locking block 441 and a fifth cylinder 442. The locking block 441 is provided with a locking groove 4410 with an opening. When the rotating unit 43 drives the turntable 41 to rotate, the locking head 4130 can move in and out of the locking groove 4410 as the turntable 41 rotates. The fifth cylinder 442 is installed on the body 1 and is connected to the locking block 441. When the turntable 41 rotates and makes the material level When 410 is aligned with the tube cutting mechanism 3 or the assembly part 42, the locking head 4130 enters the locking groove 4410. At this time, the fifth cylinder 442 drives the locking block 441 to move down and press the locking head 4130, thereby locking the turntable 41 to prevent the cutting mechanism from affecting the turntable 41 when cutting the long hose R1 or the assembly part 42 from affecting the turntable 41 when transferring the short hose R2; when the fifth cylinder 442 drives the locking block 441 to move up and release the locking head 4130, the rotation of the turntable 41 is normally controlled by the rotating unit 43.

[0058] See attached Figure 3 , Attachment Figure 14 and attached Figure 16The rotating unit 43 is of various types, and there is no restriction on this in the present invention. For the convenience of understanding, in this embodiment, the rotating unit 43 includes a rotating seat 431, a rotating shaft 432 and a third motor 433. The rotating seat 431 is mounted on the body 1, and the rotating shaft 432 is vertically and rotatably mounted in the rotating seat 431, and the head end of the rotating shaft 432 is fixedly connected to the turntable 41; the third motor 433 is mounted on the body 1, and the output end of the third motor 433 is coaxially fixedly connected to the tail end of the rotating shaft 432; starting the third motor 433 to drive the rotating shaft 432 to rotate can drive the turntable 41 to rotate; wherein, the third motor 433 can control the rotation state of its output end by a preset program, so that the turntable 41 can stop after rotating the corresponding angle, so that the material level 410 corresponds to the pipe cutting mechanism 3 and assembly, thereby ensuring the normal operation of the overall structure.

[0059] See attached Figure 1 -Attached Figure 4 and attached Figure 14 -Attached Figure 22 , a limiting spindle 10 is horizontally mounted on the machine body 1, and the assembly part 42 includes a mounting frame 421, a shaft seat 422, a carrier 423, a clamp 424, a fifth driving member 425 and a sixth driving member 426; the mounting frame 421 is slidably mounted on the machine body 1, and the shaft seat 422 is slidably mounted on the limiting spindle 10 and connected to the mounting frame 421; the carrier 423 is fixed to the shaft seat 422 and avoids the limiting spindle 10, and the clamp 424 is mounted on the carrier 423 and corresponds to the material level 410; the fifth driving member 425 is mounted on the machine body 1 and is driven by the mounting frame 421 to drive the mounting frame 421 to slide so that the clamp 424 moves closer to or away from the material level 410 on the turntable 41; the sixth driving member 426 is fixed on the mounting frame 421 and is driven by the clamp 424 to drive the clamp 424 to clamp or release the short hose R2.

[0060] Specifically, during assembly, the wire is placed next to the clamp 424 and aligned with the material level 410, and the clamp 424 is in the open state. When the rotating unit 43 controls the turntable 41 to rotate so that the material level 410 with the short hose R2 is aligned with the clamp 424, the sixth drive member 426 is first started to drive the clamp 424 to close and clamp the short hose R2, and then the fifth drive member 425 is started to drive the clamp 424 away from the material level 410 and move outward, and then the short hose R2 is transferred and put on the appropriate wire, and finally the fifth drive member 425 is started to drive the clamp 424 to open and release the short hose R2, and the sixth drive member 426 drives the clamp 424 to return to its original position; repeat the above operations to realize the automatic transfer and assembly of the short hose R2, thereby improving work efficiency.

[0061] It should be noted that a worker can hold the wire and place it next to the fixture 424 and align it with the material level 410, or a mechanical mechanism such as a robot (not shown) can move the wire to be processed to the side of the fixture 424 and align it with the material level 410, and then remove it after the short hose R2 is assembled; since the way of taking and placing the wire does not belong to the inventive point of this application, it will not be elaborated in detail in the present invention.

[0062] See attached Figure 14 -Attached Figure 24 The structures of the fifth driving member 425, the clamp 424 and the sixth driving member 426 are various, and the present invention does not limit this. For the convenience of understanding, in this embodiment, the fifth driving member 425 includes a driving gear 4251, a rack 4252 and a fourth motor 4253; the rack 4252 is fixed to the mounting bracket 421 and extends along the sliding direction of the mounting bracket 421, and the rack 4252 is meshed with the driving gear 4251; the fourth motor 4253 is mounted on the body 1, and the output end of the fourth motor 4253 is fixed to the driving gear 4251. 251, so as to drive the mounting frame 421 to slide so that the clamp 424 moves closer to or away from the material level 410 on the turntable 41; the clamp 424 includes a clamping seat 4241, a second elastic member 4242, a shifting block 4243 and a clamping claw 4244; the clamping seat 4241 is mounted on the carrier 423, and a clamping cavity 42410 is provided inside the clamping seat 4241; the shifting block 4243 is slidably mounted on the clamping seat 4241, and the head end of the shifting block 4243 is placed outside, and the tail end of the shifting block 4243 is placed in the clamping cavity 42410, and the two sides of the tail end of the shifting block 4243 are also hinged There is a first joint rod 42431; a second elastic member 4242 is arranged in the clamping cavity 42410 and abuts the tail end of the shift block 4243 and the inner wall of the clamping cavity 42410; the clamping jaws 4244 are provided with two pieces, and the two clamping jaws 4244 are provided with a second joint rod 42441, the middle parts of the two second joint rods 42441 are rotatably connected to the inner wall of the clamping cavity 42410, and the tail ends of the two second joint rods 42441 are also hinged to the two first joint rods 42431 respectively; the sixth driving member 426 includes a sliding sleeve 4261, a linkage rod 4262 and a sixth cylinder 4 263; the sliding sleeve 4261 is coaxially sleeved with the shaft seat 422, and the sliding sleeve 4261 is provided with a convex block 42610 that slides through the carrier 423; the tail end of the linkage rod 4262 is rotatably connected to the sliding sleeve 4261, and the middle part of the linkage rod 4262 is rotatably connected to the mounting frame 421; the sixth cylinder 4263 is fixed to the mounting frame 421, and the telescopic end of the sixth cylinder 4263 is hinged to the head end of the linkage rod 4262, and the sixth cylinder 4263 drives the linkage rod 4262 to swing, so as to drive the convex block 42610 to abut against or disengage from the shift block 4243.

[0063] Specifically, under normal circumstances, the sixth cylinder 4263 drives the linkage rod 4262 to swing and drives the sliding sleeve 4261 to slide forward along the shaft seat 422, so that the convex block 42610 abuts the shift block 4243, and the convex block 42610 drives the shift block 4243 to move into the clamping cavity 42410 to squeeze the second elastic member 4242, and the shift block 4243 drives the second joint rod 42441 through the first joint rod 42431 to make the two clamping claws 4244 expand with each other, ensuring that the clamp 424 is in a closed position. In the open state; when the rotating unit 43 drives the turntable 41 to rotate and makes the material level 410 with the short hose R2 align with the clamp 424, the sixth cylinder 4263 drives the linkage rod 4262 to swing and drives the sliding sleeve 4261 to slide in the opposite direction along the shaft seat 422, so that the convex block 42610 is separated from the shifting block 4243, the second elastic member 4242 releases energy to recover and drives the shifting block 4243 to reset, and the shifting block 4243 drives the second joint rod 42441 through the first joint rod 42431 to make The two clamping jaws 4244 are brought close to each other, ensuring that the clamp 424 is closed and clamps the short hose R2; at this time, the fourth motor 4253 drives the gear to rotate to drive the rack 4252 to move outward, thereby driving the mounting frame 421 to slide forward, so that the clamp 424 holding the short hose R2 is away from the material level 410 on the turntable 41, and the short hose R2 is put on the appropriate wire to complete the assembly; after the assembly is completed, the sixth cylinder 4263 drives the ridge block 42610 to abut the shift block 424 again. 3, the two clamping jaws 4244 expand toward each other, ensuring that the clamp 424 releases the short hose R2. The fourth motor 4253 then drives the gear to rotate, driving the rack 4252 to move inward, thereby causing the empty clamp 424 to move closer to the material level 410 on the turntable 41, completing the reset. After the rotating unit 43 drives the turntable 41 to rotate again, so that the material level 410 with the new short hose R2 is aligned with the angle in the open state, the above operation is repeated to transfer the new short hose R2 onto the new wire.

[0064] It should be noted that the first elastic member 51 and the second elastic member 4242 can both be springs, rubber columns (not shown) and other components with elasticity and recovery capabilities. Due to the diversity of related components, the present invention does not impose any restrictions on this. For ease of understanding, in this embodiment, the first elastic member 51 and the second elastic member 4242 are both springs. On the other hand, workers can adapt to clamping short hoses R2 of different diameters by replacing the clamp 424 with clamps 4244 of different specifications.

[0065] See attached Figure 3 and attached Figure 17 -Attached Figure 24A rotating wheel 42430 is rotatably mounted at the front end of the shift block 4243, and the convex block 42610 contacts the rotating wheel 42430 when it abuts the shift block 4243; this design can reduce the friction between the convex block 42610 and the shift block 4243, and avoid rigid collision between the two, thereby extending the service life of the clamp 424 and the sliding sleeve 4261.

[0066] See attached Figure 14 -Attached Figure 24 The assembly part 42 also includes a seventh driving member 427, a mounting cavity 4210 is provided on the mounting frame 421, and a first and a second wheels 4211 and 4212 that are mutually enclosed are rotatably mounted on the side walls of the mounting cavity 4210; the shaft seat 422 is also rotatably matched with the limiting spindle 10, and a gear disk 4220 that is coaxially sleeved with the limiting spindle 10 is mounted on the shaft seat 422, and the gear disk 4220 is located in the mounting cavity 4210, and the first and the second wheels 4211 and 4212 respectively abut against both sides of the gear disk 4220; the carrier 423 is coaxially sleeved with the limiting spindle 10, and the carrier 423 has a plurality of recesses 4230 in a circumferential array; the clamp 424 is provided with a plurality of and is circumferentially arrayed on the carrier 423, so that the plurality of shift blocks 4243 are located one by one beside the plurality of recesses 4230, and the two clamps 424 of each clamp 424 4 is used to adapt to and clamp short hoses R2 of different diameters and models; the sliding sleeve 4261 has a plurality of ridges 42610 arranged in a circular array, each of which penetrates the plurality of recesses 4230 and corresponds to the plurality of shifting blocks 4243. The sliding sleeve 4261 is also provided with an annular groove 4261h. A pulley 4262h is rotatably mounted on the tail end of the linkage rod 4262, and the pulley 4262h is positioned within and slidably engages with the annular groove 4261h. The seventh driving member 427 includes a gear rod 4271 and a fifth motor 4272. The gear rod 4271 is meshed with the outer wall of the gear disc 4220, and the gear disc 4220 can move along the gear rod 4271 as the mounting bracket 421 moves. The fifth motor 4272 is mounted on the body 1, and the output end of the fifth motor 4272 is coaxially fixed to the gear rod 4271.

[0067] Among them, the design of the first abutting wheel 4211 and the second abutting wheel 4212 respectively abutting the two sides of the toothed disc 4220 can limit the shaking of the toothed disc 4220 while reducing the friction with the toothed disc 4220, ensuring that the toothed disc 4220 can rotate normally; multiple recesses 4230 can allow multiple ridge blocks 42610 to pass through one by one, and because the inner walls of the recesses 4230 abut the ridge blocks 42610, the carrier plate 423 can drive the sliding sleeve 4261 to rotate synchronously with the help of the ridge blocks 42610 when rotating, and the annular groove 4261h on the sliding sleeve 4261 slides with the pulley 4262h on the linkage rod 4262, which can prevent the linkage rod 4262 from interfering with the rotation of the sliding sleeve 4261.

[0068] Specifically, when the position of the carrier 21 is switched by the lifting unit 23 so that the feeding part 22 transports long hoses R1 of different diameters, the worker can first start the fifth motor 4272 to drive the gear rod 4271 to rotate, so as to drive the gear plate 4220, the shaft seat 422, the slide sleeve 4261 and the carrier 423 to rotate synchronously, thereby making the clamps 424 on the carrier 423 move one by one and align the material level 410 on the turntable 41, and turn off the fifth motor 4272 after the specifications of the clamp 424 are adapted to the short hose R2; then install the above-mentioned operating steps, start the sixth cylinder 4263 and the fourth motor 4253 in sequence, and drive the current clamp 424 to transfer the adapted short hose R2 and put it on the corresponding wire.

[0069] In summary, the above structural design makes it convenient for workers to directly drive the carrier 423 to rotate through the fifth motor 4272, so that the multiple clamps 424 on the carrier 423 can be adapted to clamp short hoses R2 of different diameters one by one; compared with the method of frequently disassembling and replacing the clamps 424 to adapt to and clamp the short hose R2, this structure can complete the switching of the clamps 424 without stopping the machine, thereby improving work efficiency.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
