Description

Technical Field

[0001] This invention relates to the field of automatic assembly technology for internal sealing rings, and in particular to an automatic assembly device and method for the internal sealing ring of a magnetic damping guide. Background Technology

[0002] The automatic assembly of internal sealing rings has become relatively mature. Generally, the automatic assembly of internal sealing rings is achieved by reducing the diameter of the sealing ring or by bending it.

[0003] Chinese Patent CN202010929117.3 discloses an internal sealing ring installation device and method, including an elastic push rod, a shrink sleeve, a transition tube, and a push rod. The shrink sleeve has a shrinkage through hole with a trapezoidal vertical cross-section. The larger end of the shrinkage through hole is the inlet end, and the smaller end is the outlet end. The inlet end of the shrink sleeve matches the outer diameter of the internal sealing ring, and the outlet end of the shrink sleeve matches the inner diameter of the transition tube. The transition tube is a hollow tubular structure. The elastic push rod has elastic claws that bend and compress the internal sealing ring from the shrinkage through hole of the shrink sleeve and then feed it into the transition tube. The transition tube delivers the internal sealing ring into the mounting hole of the workpiece. This invention automates the assembly of internal sealing rings, especially automating the installation of internal sealing rings in small-sized internal threaded holes, greatly improving production efficiency and reducing labor costs.

[0004] However, the technical solution does not disclose how to achieve automated assembly and the deformation mode of the sealing ring is unstable. The deformation failure of the sealing ring leads to assembly failure or high failure rate. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic assembly device for the inner sealing ring of a magnetic vibration damping guide. The device uses a sorting unit to transport the sealing rings one by one to a feeding unit. The feeding unit then transfers multiple sealing rings synchronously to a deformation unit, which deforms the sealing rings into a U-shaped structure and transfers them to an assembly unit. This, in conjunction with the assembly unit, achieves automated assembly of the inner sealing rings. This results in high production efficiency, stable sealing ring deformation quality, and a low assembly failure rate, thus solving the problems of high assembly failure rate and low production efficiency in existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] This invention provides an automatic assembly device for the inner sealing ring of a magnetic vibration damping guide, including a frame and a sorting unit, a feeding unit, a deformation unit, and an assembly unit mounted on the frame.

The feeding unit transfers the sealing rings output one by one from the sorting unit to the deformation unit. The deformation unit deforms the circular sealing rings so that their outer contour is smaller than that of the sealing ring in its natural state, and then transfers them to the assembly unit. The assembly unit transfers the upper guide and the lower guide to one side of the deformation unit, and then, in conjunction with the deformation unit, assembles the deformed sealing rings into the inner holes of the upper guide and the lower guide.

[0010] According to one embodiment of the present invention, the deformation unit includes: a base deformation component, which is installed above the base and deforms the circular sealing ring so that its outer contour is smaller than that of the sealing ring in its natural state, so that the deformed sealing ring can be smoothly assembled to the sealing part that needs to be internally sealed; and a material transfer component, which holds the deformed sealing ring in the deformed state and transfers it to the assembly unit for assembly.

[0011] According to one embodiment of the present invention, the deformation assembly includes: a guide plate having a guide groove; the guide groove sequentially including a push guide section, a deformation guide section, and a deformation holding section; a push plate slidably disposed on the guide plate; a deformation push rod slidably disposed within the guide groove and moving synchronously with the push plate; the front end of the deformation push rod having a forming portion and a protrusion for extruding a deformation sealing ring; and a push plate driving unit that drives the push plate to reciprocate, which is mounted on one side of the base and its output end is connected to the push plate.

[0012] According to one embodiment of the present invention, the deformation assembly further includes a material ejection assembly disposed below the guide plate for ejecting the deformed sealing ring; the material ejection assembly includes: an ejection rod, which is configured to reciprocate vertically downward, and its top end can pass through the guide plate and the push plate to eject the sealing ring from the deformation holding section; and an ejection drive unit, which is mounted on the base, and the output end of the ejection drive unit is connected to the ejection rod.

[0013] According to one embodiment of the present invention, the material transfer assembly includes: a horizontal moving module; a first vertical moving module mounted on the horizontal moving module; a second vertical moving module mounted on the first vertical moving module; a material picking cylinder mounted on the first vertical moving module; and a material discharging rod mounted on the second vertical moving module, the second vertical moving module driving the material discharging rod to reciprocate vertically.

[0014] According to one embodiment of the present invention, the assembly unit includes: a guide loading / unloading assembly and an assembly assembly, wherein the guide loading / unloading assembly transfers the guide to the assembly assembly, and the assembly assembly positions the guide; the guide loading / unloading assembly includes: a clamping part, wherein the clamping part is provided with multiple sets of grippers; and a clamping drive part, wherein the clamping drive part drives the clamping part to move along the X-axis and the Z-axis.

[0015] According to one embodiment of the present invention, the assembly assembly is slidably disposed on the frame, and includes: a guide carrier for transferring and positioning an upper guide and a lower guide, the guide carrier being slidably disposed on the frame; a positioning seat, a plurality of positioning seats being mounted on the guide carrier, the upper end of the positioning seat having an opening for clamping the guide; and a carrier drive unit, the carrier drive unit driving the guide carrier to reciprocate.

[0016] This invention also provides an automatic assembly method for the inner sealing ring of a magnetic damping guide, which is implemented using the aforementioned automatic assembly equipment for the inner sealing ring of a magnetic damping guide, and includes the following steps:

[0017] Seal ring sorting: The vibratory feeder outputs the seal rings one by one to the positioning space on the feeding positioning plate;

[0018] Sealing ring feeding: The feeding drive unit drives the feeding gripper to simultaneously grab the sorted sealing rings to the deformation component;

[0019] Sealing ring deformation: The deformation component deforms the sealing ring so that its outer contour is smaller than the contour of the sealing ring in its natural state;

[0020] Seal ring transfer: The material take-up cylinder moves above the deformed seal ring, and the material ejector rod transfers the deformed seal ring into the material take-up cylinder;

[0021] Sealing ring assembly: The material transfer assembly moves the material picking cylinder to the top of the guide carrier, and the discharge rod pushes the sealing ring in the material picking cylinder into the upper and lower guides. Through the deformation of the sealing ring, the internal seal assembly is completed.

[0022] The beneficial effects of this invention are as follows:

[0023] (1) The present invention delivers the sealing rings one by one to the feeding unit through the sorting unit. After the feeding unit transfers multiple sealing rings to the deformation unit at the same time, the deformation unit deforms the sealing rings into a U-shaped structure and transfers them to the assembly unit. The assembly unit cooperates with the assembly unit to realize the automated assembly of the inner sealing rings. The production efficiency is high, the deformation quality of the sealing rings is stable, and the assembly failure rate is low.

[0024] (2) In the sorting process, the present invention uses the feeding transverse unit to drive the feeding positioning plate to move back and forth, and delivers the sealing rings on the vibratory plate to different positioning spaces one by one, thereby realizing the automated feeding of multiple sealing rings. At the same time, multiple sealing rings can be grabbed at one time and processed simultaneously.

[0025] (3) The present invention transforms the sealing ring from a circular structure to a U-shaped structure through the deformation component, thereby reducing the outer contour size of the sealing ring. The deformed sealing ring is transferred in conjunction with the material transfer component. When the inner sealing assembly is required, the discharge rod pushes the sealing ring out of the material taking cylinder to realize the automatic assembly of the inner sealing ring.

[0026] (4) The present invention sets a deformation push rod and a guide plate at the bottom of the push plate to realize the spatial pushing of the sealing ring in three directions: upper, lower and tail. The sealing ring is pushed in the forward direction, which improves the deformation quality of the sealing ring and avoids the sealing ring from running around randomly, resulting in inconsistent quality after deformation.

[0027] (5) The present invention uses a material transfer component in conjunction with a material ejection component to automatically eject the sealing ring and grab it according to its deformed state, thereby realizing the rapid transfer of the deformed sealing ring and ensuring the stability of the deformation state of the sealing ring, thus improving the assembly success rate of the inner sealing ring.

[0028] In summary, the present invention has the advantages of high automation, high production efficiency, simultaneous assembly of sealing rings for upper and lower guides, and low assembly failure rate. Attached Figure Description

[0058] Example 1

[0059] like Figures 1-2 As shown, this embodiment provides an automatic assembly equipment for the inner sealing ring of a magnetic damping guide, including a frame 1 and a sorting unit 2, a feeding unit 3, a deformation unit 4 and an assembly unit 5 installed on the frame 1;

[0060] The sorting unit 2 is installed on one side of the frame 1, the deformation unit 4 is installed on the adjacent side of the sorting unit 2, the feeding unit 3 is installed between the sorting unit 2 and the deformation unit 4, and the assembly unit 5 is installed on the other side of the deformation unit 4.

[0061] The feeding unit 3 transfers the sealing rings output one by one from the sorting unit 2 to the deformation unit 4. The deformation unit 4 deforms the circular sealing rings so that their outer contours are smaller than the natural contours of the sealing rings, and then transfers them to the assembly unit 5. The assembly unit 5 transfers the upper guide 200 and the lower guide 300 to one side of the deformation unit 4, and then, in conjunction with the deformation unit 4, assembles the deformed sealing rings into the inner holes of the upper guide 200 and the lower guide 300.

[0062] As an improvement, such as Figures 3-4 As shown, the sorting unit 2 includes:

[0063] Vibratory feeder 21 outputs the sealing rings one by one;

[0064] A feeding positioning plate 22 is installed at the output end of the vibratory feeder 21. The feeding positioning plate 22 has several positioning spaces 221. The sealing rings output by the vibratory feeder 21 are transmitted to the positioning spaces 221 one by one. A detection sensor is also provided on one side of the feeding positioning plate 22 to detect whether there is a sealing ring in the positioning space 221. After the sensor detects that there is no sealing ring in the space, the vibratory feeder 21 conveys a sealing ring forward. In this embodiment, the feeding positioning plate 22 preferably has two positioning spaces 221.

[0065] The feeding transverse movement unit 23 is located at the bottom of the feeding positioning plate 22. The feeding transverse movement unit 23 drives the feeding positioning plate 22 to move back and forth, so that several positioning spaces 221 are aligned sequentially with the output end of the vibrating plate 21, so that multiple sealing rings are fed into the positioning spaces 221 and multiple sealing rings are grabbed at one time. The feeding transverse movement unit 23 is driven by a cylinder to make the feeding positioning plate 22 move back and forth.

[0066] Preferred, such as Figures 3-4 As shown, the feeding unit 3 includes:

[0067] The feeding gripper 31 is provided in multiple ways, and the spacing between the multiple feeding grippers 31 is adapted to the spacing between a number of positioning spaces 221; specifically, there are two feeding grippers 31.

[0068] The feeding drive unit 32 is equipped with the feeding gripper 31. The feeding drive unit 32 drives the feeding gripper 31 to reciprocate along the Y-axis and Z-axis. Specifically, the feeding drive unit 32 adopts a linear drive module, such as a cylinder driving the slider to reciprocate along the guide rail.

[0069] The feeding gripper 31 includes: a gripper connecting plate 311 and a plurality of fourth driving members 312 installed below the gripper connecting plate 311. The output end of the fourth driving member 312 is connected to a mechanical claw 313 for gripping the sealing ring. Specifically, in this embodiment, the sealing ring is preferably internally supported to achieve the gripping of the sealing ring. The output end of the fourth driving member 312 is connected to two mechanical claws 313. The fourth driving member 312 drives the mechanical claws 313 to move back and forth, changing the spacing of the mechanical claws 313 to achieve the internal support and gripping of the sealing ring. At the same time, it is convenient to unload the sealing ring.

[0070] Furthermore, a sensor is provided on one side of the feeding gripper 31 to detect whether a sealing ring is being held on the feeding gripper 31.

[0071] In addition, such as Figure 5As shown, the sorting unit 2, feeding unit 3, deformation unit 4 and assembly unit 5 can be set in multiple groups to achieve efficient assembly of the sealing rings. They are not limited to symmetrical arrangement, linear array arrangement, circumferential array arrangement and other methods.

[0072] Example 2

[0073] like Figures 6-13 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0074] In this embodiment, as Figure 6 As shown, the deformation unit 4 includes:

[0075] The base 41 has a double-sided structure, including an upper support plate 411 and a lower support plate 412, supported by several support rods 413 in the middle; it also includes:

[0076] Deformation component 42 is installed above the base 41. The deformation component 42 deforms the circular sealing ring so that its outer contour is smaller than the contour of the sealing ring in its natural state, so that the deformed sealing ring can be smoothly assembled into the sealing part that needs to be sealed internally. Specifically, when the sealing part that needs to be sealed internally, such as the inner diameter surface of a tubular structure, is to be sealed, the contour of the sealing ring is deformed to a state smaller than the contour size of the inner diameter surface, so that the sealing ring can be smoothly assembled into the inner diameter surface. Through the automatic elastic recovery of the sealing ring, the automatic assembly of the inner sealing ring is realized.

[0077] And a transfer component 43, which holds the deformed sealing ring of the deformation component 42 in a deformed state and transfers it to the assembly unit 5 for assembly.

[0078] As an improvement, such as Figure 8 As shown, the deformation component 42 includes:

[0079] Guide plate 421, on which guide groove 4211 is provided; guide groove 4211 includes push guide section 42111, deformation guide section 42112, and deformation holding section 42113 in sequence.

[0080] A push plate 422 is slidably disposed on the guide plate 421. The push plate 422 limits the upper part of the guide groove 4211, so that the sealing ring moves smoothly along the guide groove 4211. The push plate 422 pushes the sealing ring from the deformation guide section 42112 to the deformation holding section 42113, completing the deformation of the sealing ring. Specifically, the push plate 422 is slidably disposed above the base 41, and guide rails are provided on both sides of the push plate 422.

[0081] Deformation push rod 423 is slidably disposed in the guide groove 4211 and moves synchronously with the push plate 422; the front end of the deformation push rod 423 is provided with a forming part 4231 and a protrusion 4232 for extruding and deforming sealing ring.

[0082] Specifically, the deformation push rod 423 is installed at the bottom of the push plate 422 by fasteners. As the push plate 422 moves, it pushes the sealing ring from the deformation guide section 42112 to the deformation holding section 42113. The protrusion 4232 causes the sealing ring to deform inward, thereby reducing the outline of the sealing ring.

[0083] The push plate drive unit 424 drives the push plate 422 to move back and forth. It is installed on one side of the base 41 and its output end is connected to the push plate 422.

[0084] The front end of the forming part 4231 is arranged in an arc structure, and a protrusion 4232 for extruding and deforming the sealing ring is provided in the middle of the arc structure. A deformation holding space is formed between the forming part 4231 and the inner wall of the deformation holding section 42113. Specifically, when the deformation push rod 423 moves to the front end, the forming part 4231 and the arc section of the deformation holding section 42113 form a circular deformation holding space, that is, the outer contour of the sealing ring is deformed into an approximately circular structure, so as to facilitate the material removal in the subsequent process.

[0085] Preferred, such as Figure 9 As shown, the deformation guide section 42112 includes a feeding section 421121 and a deformation section 421122 with gradually decreasing size. The outline of the feeding section 421121 is adapted to the outline size of the sealing ring in its natural state.

[0086] Furthermore, the push guide section 42111 is arranged in parallel, and the contour of the deformation retaining section 42113 is adapted to the contour of the deformed sealing ring; specifically, it is preferably a U-shaped structure, and the bottom of the U-shaped structure is a semi-circular structure.

[0087] Furthermore, such as Figure 8 As shown, the deformation push rod 423 moves forward, pushing the sealing ring to move along the deformation guide section 42112, and deforms in the gradually decreasing deformation guide section 42112, so that the part of the sealing ring that contacts the protrusion 4232 is concave inward to form a double-layer U-shaped structure, thereby reducing the outer contour size of the sealing ring.

[0088] Preferred, such as Figure 7 As shown, the deformation assembly 42 further includes a material ejection assembly 44 disposed below the guide plate 421 for ejecting the deformed sealing ring; the material ejection assembly 44 includes:

[0089] The ejector rod 441 is vertically downward reciprocating, and its top end can pass through the guide plate 421 and the push plate 422 to push the sealing ring out from the deformation holding section 42113; the top contour of the ejector rod 441 is adapted to the contour of the deformation holding space; that is, the side wall of the ejector rod 441 is provided with a relief groove 4411, and the contour of the relief groove 4411 is adapted to the contour of the protrusion 4232;

[0090] And a material ejection drive unit 442, which is mounted on the base 41, and the output end of the material ejection drive unit 442 is connected to the material ejection rod 441; the material ejection drive unit 442 can be selected by cylinder transmission, hydraulic transmission or other methods.

[0091] Preferably, the bottom of the deformation holding section 42113 is provided with a through hole adapted to the deformation holding space. The ejector rod 441 is inserted into the through hole and is adapted to the size of the through hole. When the sealing ring deforms, the top surface of the ejector rod 441 is flush with the bottom surface of the deformation holding section 42113, so that the bottom surface of the deformation holding section 42113 is planar. When the forming part 4231 moves forward to deform the sealing ring, the clearance groove 4411 corresponds to the protrusion 4232. When it is necessary to eject the deformed sealing ring, the ejector rod 441 moves upward to push out the deformed sealing ring.

[0092] Example 3

[0093] like Figure 6 , Figure 11 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 3 and Embodiment 1 is as follows:

[0094] As an improvement, the transfer assembly 43 includes:

[0095] The horizontal moving module 431 includes a first connecting plate 4311, a first driving member 4312, and a first guide rail slider 4313. The first connecting plate 4311 is slidably disposed above the deformation component 42 via the first guide rail slider 4313. The output end of the first driving member 4312 is connected to the first connecting plate 4311, driving the first connecting plate 4311 to reciprocate.

[0096] A first vertical moving module 432 is mounted on the horizontal moving module 431. Specifically, the first vertical moving module 432 includes a second connecting plate 4321, a second driving member 4322, and a second guide rail slider 4323. The second connecting plate 4321 is slidably disposed on one side of the first connecting plate 4311 via the second guide rail slider 4323. The second driving member 4322 is disposed at the top of the first connecting plate 4311, and its output end is connected to the second connecting plate 4321, driving the second connecting plate 4321 to move vertically back and forth.

[0097] A second vertical moving module 433 is mounted on the first vertical moving module 432. The second vertical moving module 433 includes a third driving component 4331, which is mounted on one side of the second connecting plate 4321, and its output end is connected to a discharge rod 435.

[0098] Material picking cylinder 434 is installed on the first vertical moving module 432. Specifically, the material picking cylinder 434 is installed at the bottom of the second connecting plate 4321.

[0099] And a discharge rod 435, which is mounted on the second vertical moving module 433. The second vertical moving module 433 drives the discharge rod 435 to move vertically back and forth, so that the discharge rod 435 slides in the material taking cylinder 434. Specifically, the top end of the discharge rod 435 is connected to the output end of the third driving member 4331, and its lower end is slidably disposed in the material taking cylinder 434.

[0100] Specifically, the horizontal moving module 431 drives the first vertical moving module 432 to reciprocate, and the first vertical moving module 432 drives the picking cylinder 434 to reciprocate vertically. When picking up material, the picking cylinder 434 moves downward with the first vertical moving module 432 and inserts into the upper part of the deformation holding space to abut against the deformed sealing ring. The ejector rod 441 moves upward and pushes the deformed sealing ring into the inner cavity of the picking cylinder 434. During the pushing process, the discharge rod 435 moves upward synchronously, so that the sealing ring keeps moving upward smoothly and enters the inner cavity of the picking cylinder 434.

[0101] Subsequently, through the cooperation of the horizontal moving module 431, the first vertical moving module 432, and the second vertical moving module 433, the feeding cylinder 434 is sent to the corresponding inner hole of the product to be assembled. Then, the discharge rod 435 moves downward to push the deformed sealing ring into the inner hole of the product to be assembled, thus completing the automatic assembly of the inner sealing ring.

[0102] The horizontal moving module 431, the first vertical moving module 432, and the second vertical moving module 433 each include a support frame, a driving component, and a guide rail.

[0103] Furthermore, in this embodiment, the guide groove 4211 is symmetrically opened on the guide plate 421, and the push plate 422 simultaneously drives two sets of deformation push rods 423 to realize the simultaneous deformation of the two sets of sealing rings;

[0104] In addition, two sets of ejector bars 441 are provided, which are synchronously driven by a set of ejector drive units 442 to achieve efficient ejection.

[0105] In addition, two sets of material picking cylinders 434 and material discharge rods 435 are provided to achieve synchronous material picking.

[0106] Example 4

[0107] like Figures 14-15 As shown, components that are the same as or corresponding to those in Embodiment 3 are referred to using the same reference numerals as those in Embodiment 3. For simplicity, only the differences from Embodiment 3 will be described below. The difference between Embodiment 4 and Embodiment 3 is as follows:

[0108] In this embodiment, the assembly unit 5 includes: a guide loading / unloading assembly 51 and an assembly assembly 52. ​​The guide loading / unloading assembly 51 transfers the guide to the assembly assembly 52, and the assembly assembly 52 positions the guide. Specifically, the assembly assembly 52 moves below the guide loading / unloading assembly 51, the guide loading / unloading assembly 51 loads the guide to the assembly assembly 52, and the assembly assembly 52 moves to the deformation unit 4 to install the deformed sealing ring on the inner diameter surface of the guide.

[0109] The guide loading / unloading assembly 51 includes:

[0110] The clamping part 511 is provided with multiple sets of grippers, which clamp multiple sets of upper guides 200 and lower guides 300. The clamping part 511 uses a bidirectional cylinder to drive the grippers, and the grippers are provided with V-shaped positioning parts to realize automatic centering of the guides. In this embodiment, four sets of grippers are preferably provided, two sets for loading and two sets for unloading, so as to achieve efficient loading and unloading.

[0111] The clamping drive unit moves the clamping part 511 along the X and Z axes, causing the clamping part 511 to simultaneously clamp and self-center the upper guide 200 and lower guide 300 located on the guide transfer seat, thereby achieving precise positioning of the guides and improving the feeding accuracy of the guides. Specifically, the clamping drive unit can be implemented using a cylinder and guide rail slider structure; the structure of the clamping drive unit is not shown in the figures of this application.

[0112] The clamping part 511 is also equipped with a visual inspection device 512 for checking whether the sealing ring is assembled, and for detecting whether there is a sealing ring at the loading station.

[0113] As an improvement, the assembly component 52 is slidably disposed on the frame 1, and includes:

[0114] Guide carrier 521, used for transporting and positioning upper guide 200 and lower guide 300, is slidably mounted on frame 1;

[0115] Positioning seats 522, multiple positioning seats 522 are installed on the guide carrier 521. The inner diameter of the positioning seat 522 is adapted to the outer diameter of the guide. At the same time, the upper end of the positioning seat 522 has an opening for clamping part 511 to clamp the guide, so that the clamping part 511 can clamp the middle part of the guide, improving clamping stability and the stability of the guide on the guide carrier 521 during the transfer process. The positioning seats 522 are used to hold one or both of the upper guide 200 and the lower guide 300.

[0116] The vehicle drive unit 523 drives the guide vehicle 521 to reciprocate; specifically, the vehicle drive unit 523 can be selected to be cylinder driven, and the bottom of the guide vehicle 521 is slidably connected to the frame 1 through a guide rail slider, and the guide vehicle 521 is driven to reciprocate by the cylinder.

[0117] The number of positioning seats 522 of the guide carrier 521 is set in correspondence with the number of clamping parts 511, so as to clamp multiple guides at one time and improve production efficiency. In this application, two positioning seats 522 are preferably set to realize the simultaneous installation of upper guide 200 and lower guide 300 at one time.

[0118] During operation, the clamping drive unit drives the clamping unit 511 to feed the upper guide 200 and the lower guide 300 into the positioning seat 522. Then, the carrier drive unit 523 carries the guide carrier 521 to the deformation unit 4, and together with the deformation unit 4, the deformed sealing ring is simultaneously assembled into the inner hole of the upper guide 200 and the lower guide 300.

[0119] After assembly, the vehicle drive unit 523 carries the guide carrier 521 to the lower part of the clamping unit 511. The clamping unit 511 clamps the assembled upper guide 200 and lower guide 300 and puts the new upper guide 200 and lower guide 300 to be assembled into the positioning seat 522.

[0120] Example 5

[0121] like Figure 16 As shown, this embodiment provides an automatic assembly method for the inner sealing ring of a magnetic damping guide, which is completed using the automatic assembly equipment for the inner sealing ring of a magnetic damping guide described in Embodiments 1 to 4, and includes the following steps:

[0122] Seal ring sorting: Vibratory feeder 21 outputs the seal rings one by one to the positioning space 221 on the feeding positioning plate 22;

[0123] Sealing ring feeding: The feeding drive unit 32 drives the feeding gripper 31 to simultaneously grab the sorted sealing rings to the deformation component 42;

[0124] Deformation of the sealing ring: The deformation component 42 deforms the sealing ring so that its outer contour is smaller than the contour of the sealing ring in its natural state;

[0125] Seal ring transfer: The material taking cylinder 434 moves to the top of the deformed seal ring, and the material ejecting rod 441 transfers the deformed seal ring into the material taking cylinder 434;

[0126] Sealing ring assembly: The material transfer assembly 43 drives the material take-up cylinder 434 to move above the guide carrier 521. The material discharge rod 435 pushes the sealing ring in the material take-up cylinder 434 into the upper guide 200 and the lower guide 300. The internal sealing assembly is completed by the deformation of the sealing ring.

[0127] Preferably, in the sealing ring sorting process, the feeding transverse transfer unit 23 drives the feeding positioning plate 22 to move, and transports the sealing rings on the vibrating plate 21 to different positioning spaces 221 one by one.

[0128] Preferably, in the sealing ring feeding process, multiple feeding claws 31 simultaneously grasp multiple sealing rings and move synchronously.

[0129] Preferably, in the sealing ring deformation process, the push plate drive unit 424 drives the deformation push rod 423 to push the sealing ring forward along the guide groove 4211, and deforms in the gradually decreasing deformation guide section 42112, so that the circular sealing ring is deformed into a double-layer U-shaped structure, reducing the outer contour of the sealing ring.

[0130] Preferably, in the sealing ring transfer process, during the process of the material taking cylinder 434 grabbing the deformed sealing ring, the material ejector rod 441 abuts against the top of the deformed sealing ring and pushes the sealing ring into the material taking cylinder 434 simultaneously with the material ejector rod 441.

[0131] Preferably, in the sealing ring assembly process, the clamping part 511 is provided with multiple sets of grippers, of which two sets grip the guide to be assembled and two sets grip the assembled guide, so as to realize rapid loading and unloading.

[0132] Preferably, in the sealing ring assembly process, the carrier drive unit 523 carries the positioning seat 522 to move back and forth, realizing the switching between loading / unloading and assembly.

[0133] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
