Description

Technical Field

[0001] This invention relates to the field of magnetic damping guide assembly technology, and in particular to an automatic assembly device for sliding bearings inside a magnetic damping guide. Background Technology

[0002] The guide is a crucial component of the shock absorber, its primary function being to guide the vertical movement of the piston rod. Current technologies rely on manual assembly, which depends heavily on operator skill and experience. This not only makes product quality susceptible to human error but also results in low work efficiency. Due to the non-repeatable nature of manual operations, product quality often fluctuates, making consistency difficult and prone to errors, leading to a high scrap rate.

[0003] Even with semi-automated equipment, manual intervention is often required in processes such as parts loading, pre-pressing, pressing, and inspection. This not only slows down production speed but also increases labor intensity and production costs. In addition, semi-automated equipment is often less precise than fully automated equipment in terms of inspection and quality control, and cannot monitor product quality in real time, thus affecting the output efficiency and product reliability of the entire production line.

[0004] Chinese patent CN217152810U discloses an assembly structure for a shock absorber guide and oil seal, including an outer cylinder, a guide, an oil seal, and an auxiliary mounting ring. The guide and oil seal are both installed inside the outer cylinder. The oil seal includes a vulcanized metal skeleton and a rubber body. The lower end of the rubber body is provided with an annular sealing body. The upper end of the guide is provided with an annular boss. The auxiliary mounting ring is made of rubber and is sleeved on the outside of the annular boss. The annular sealing body is sleeved on the outside of the auxiliary mounting ring, and the annular sealing body is interference-fitted with the inner wall of the outer cylinder.

[0005] However, this technical solution cannot enable a single device to simultaneously complete the assembly of the upper guide and bearing as well as the assembly of the lower guide and bearing. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an automatic assembly device for sliding bearings inside magnetic damping guides. Through the guide mounting mechanism and the bearing mounting mechanism, the upper guide, lower guide, and bearing are output one by one, and the output components are arranged in a specific position. Then, the transfer mechanism clamps and transfers the components, and the assembly mechanism combines and assembles them, thus solving the problem that it is impossible to complete the assembly of the upper guide and bearing and the lower guide and bearing simultaneously with a single device.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0013] The upper guide feeding assembly and the lower guide feeding assembly output the upper guide and the lower guide one by one synchronously, respectively. At the same time, the bearing mounting mechanism outputs two bearings side by side synchronously. After the upper guide, the lower guide and the two bearings move to the mounting station of the transfer mechanism, the transfer mechanism transfers them together to the assembly mechanism and places them on the rotating assembly. At this time, the two bearings are placed on the upper guide and the lower guide respectively. The rotating assembly moves to the stamping assembly to complete the stamping and riveting work, and then transmits to the output assembly.

[0033] Preferably, the transfer mechanism includes:

[0034] The fifth sliding frame slides horizontally on the fifth sliding track;

[0035] A fourth drive unit, which is mounted on the fifth sliding frame and has a sixth sliding frame at its output end; and

[0036] The second pneumatic gripper is provided in four sets and is installed on the sixth sliding frame.

[0037] Preferably, the rotating assembly includes:

[0038] The second turntable rotates on the second mounting platform and rotates intermittently in a circular motion under the drive of the fifth drive unit;

[0039] The fixture is detachably provided in several groups along the circumferential direction of the second turntable. It includes a base that is inserted and locked onto the second turntable, a mounting seat that is elastically slidable on the base through a second elastic unit, a first mounting cylinder and a second mounting cylinder mounted on the mounting seat.

[0040] Both the first and second mounting cylinders have clearance grooves at their upper ends and mounting posts are elastically arranged inside them.

[0053] The beneficial effects of this invention are as follows:

[0054] 1. The present invention realizes the sequential output of the upper guide, lower guide and bearing through the guide upper mounting mechanism and the bearing upper mounting mechanism, and makes the above-mentioned components output one by one distributed in a specific position. Then the transfer mechanism clamps and transfers the above-mentioned components, and assembles them through the assembly mechanism. The output efficiency of the entire production line is high and the product reliability is high.

[0055] 2. This invention uses a switching component to cooperate with a storage component, allowing the storage component to be detachably installed in the mounting slot. After all the upper or lower guides in a set of storage components have been output, the first turntable automatically switches to move the next set of storage components to the feeding component position. The upper or lower guides in the storage components are then output one by one by the pushing component, thereby achieving continuous assembly, batch output, and reducing labor intensity and production costs.

[0056] 3. This invention utilizes a stamping assembly. On one hand, the bearing is first stamped using a forming part to ensure it is fully in place. Then, the upper end of the guide is riveted, deforming the guide and confining the bearing within it. A first positioning part further supports the lower part of the fixture, ensuring the stamped bearing is in place. On the other hand, a translation part, in conjunction with the fixture, allows switching between the first and second mounting cylinders located below the forming part. This enables the bearing installation of two guides to be completed within a single tooling, saving equipment investment costs and improving work efficiency.

[0057] 4. This invention uses an output component in conjunction with a rejection component. The shaping unit is located in the upper or lower guide bearing for downward stamping and adjustment. After stamping and shaping, it is inspected. Qualified products are clamped and output by a robotic arm, while unqualified products are output to the next workstation. The rejection component clamps and outputs defective products. By using the settings of automated equipment, the product quality is stable, and its inspection and quality control are precise.

[0058] In summary, the present invention has advantages such as high automation. Attached Figure Description

Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0078] Example 1

[0079] like Figure 1-2 As shown, this embodiment provides an automatic assembly device for sliding bearings inside a magnetic damping guide, comprising:

[0080] The guide upper mounting mechanism 1 includes an upper guide feeding assembly 11 and a lower guide feeding assembly 12 arranged symmetrically on the left and right sides.

[0081] Bearing mounting mechanism 2, which is disposed between the upper guide feeding assembly 11 and the lower guide feeding assembly 12;

[0082] Transfer mechanism 3, wherein the transfer mechanism 3 is disposed at the output end of the bearing mounting mechanism 2; and

[0083] Assembly mechanism 4, located at the output end of transfer mechanism 3, includes a rotating component 41, a stamping component 42, an output component 43, and a rejection component 44 arranged sequentially along the transmission direction of the rotating component 41.

[0084] Furthermore, such as Figure 3-6 The upper guide feeding assembly 11 and the lower guide feeding assembly 12 both include:

[0085] Switching component 111 includes a first turntable 1113 that rotates on a first mounting platform 1111 and rotates intermittently in a circular motion under the drive of a first driving unit 1112. The first turntable 1113 has a plurality of sets of mounting slots 1114 sequentially opened along the circumferential direction.

[0086] Storage component 112 is fitted and snapped onto the mounting slot 1114;

[0087] The feeding assembly 113 includes a second drive unit 1131 installed on the first mounting platform 1111 and automatically opening the storage assembly 112, and a pusher 114 disposed below the storage assembly 112 and transferring the output guide to the workstation.

[0088] It should be noted that the upper guide feeding assembly 11 and the lower guide feeding assembly 12 work synchronously, with high synchronization and easy control.

[0089] Furthermore, such as Figure 4-5 The storage component 112 includes:

[0090] A material box 1121 is provided with a vertically penetrating material discharge hole 1120 and a material pusher opening 1122 on its side end.

[0091] A push plate 1123 is horizontally slidably disposed in the loading box 1121 via a first elastic unit. The push plate 1123 is provided with a smoothly transitioned and connected material blocking hole 1124 and a material discharge hole 1125.

[0092] A storage cylinder 1126 is vertically mounted on the loading box 1121;

[0093] Once the storage cylinder 1126, the discharge hole 1125, and the drop hole 1120 are aligned, the guide will automatically output downwards;

[0094] The inner diameter of the plugging hole 1124 is smaller than the inner diameter of the discharge hole 1125, and the inner diameter of the discharge hole 1125 is smaller than the inner diameter of the dropping hole 1120.

[0095] In this application, the automatic switching between the blocking hole 1124 and the discharge hole 1125 is achieved by moving the push plate 1123 back and forth, so as to complete the limiting storage or release of the guide in the storage cylinder 1126 under two working conditions.

[0096] It should be noted that when the discharge hole 1120, the blocking hole 1124, and the storage cylinder 1126 are coaxial, the inner diameter of the blocking hole 1124 is smaller than the inner diameter of the discharge hole 1125 and smaller than the guide, thus achieving the interception of the guide at the lower end.

[0097] Conversely, when the discharge hole 1120, the discharge hole 1125, and the storage cylinder 1126 are coaxial, since the inner diameters of the discharge hole 1120 and the discharge hole 1125 are both larger than the diameter of the upper guide or the lower guide, the upper guide or the lower guide will automatically output downwards.

[0098] Furthermore, by setting the push port 1122, the second drive unit 1131 passes through the push port 1122 and acts on the push plate 1123. After all the upper guides or lower guides in the storage cylinder 1126 have been output, the second drive unit 1131 is withdrawn, the push plate 1123 is automatically reset, and the loading of the next set of upper guides or lower guides is completed.

[0099] Furthermore, such as Figure 6 The pusher 114 includes:

[0100] The first sliding frame 1141 slides horizontally on the first sliding track 1142;

[0101] The first pneumatic gripper 1143 is mounted on the first sliding frame 1141;

[0102] A limiting plate 1144 is located on one side of the first pneumatic gripper 1143 and is mounted on the first sliding frame 1141.

[0103] The second sliding frame 1145 slides vertically on the second sliding rail 1146, which is mounted on the first sliding frame 1141.

[0104] The first support platform 1146 is mounted on the second sliding frame 1145 and moves within the clamping range of the first pneumatic gripper 1143.

[0105] In this application, by setting the pusher 114, after the upper guide or lower guide is output from the discharge hole 1120, the first support platform 1146 is located at the lower end of the discharge hole 1120. After contacting the upper guide or lower guide, it slowly moves down to achieve stable output of the upper guide or lower guide and prevent it from falling. Until the upper guide or lower guide is completely separated from the discharge hole 1120, that is, the upper guide or lower guide of the discharge hole is located in the clamping range of the first pneumatic gripper 1143, the first pneumatic gripper 1143 clamps the upper guide or lower guide, and after clamping, it slides through the first sliding frame 1141 to complete the transfer output of the upper guide or lower guide. During this process, the limiting plate 1144 moves synchronously to limit the next set of upper guides or lower guides to be output and prevent them from falling.

[0106] Furthermore, such as Figure 7-8 The bearing mounting mechanism 2 includes:

[0107] The third sliding frame 21 slides horizontally on the third sliding track 22, and push blocks 23 are provided at both ends of the third sliding frame 21;

[0108] The discharge component 24 is provided in two sets and symmetrically arranged on both sides of the third sliding rail 22. The discharge component 24 includes a fourth sliding rail 241, several sets of storage cylinders 242 arranged sequentially along the length direction of the fourth sliding rail 241, a locking unit 243 located at the lower end of the storage cylinder 242 and used to limit the bearing in the storage cylinder 242, and a third drive unit 244 perpendicular to the moving direction of the third sliding frame 21 and used to push the bearing output from the storage cylinder 242 to the fourth sliding rail 241.

[0109] In this application, two sets of discharge components 24 are symmetrically arranged on both sides of the third sliding track 22, and the bearings that are simultaneously output from both sides are output outward by the third sliding frame 21, thereby achieving the effect of one output and two outputs, so that the output rhythm of the bearings is the same.

[0110] In detail, for any set of discharge components 24, several sets of storage cylinders 242 are set above the fourth sliding track 241, so that when the bearings in any set of storage cylinders 242 are used up during continuous operation, they can be replaced manually. During the replacement process, the bearings in the other set of storage cylinders 242 can be output one by one, thereby realizing the continuous output of bearings. This facilitates seamless connection with the subsequent continuous guide assembly work and improves work efficiency.

[0111] Meanwhile, the material locking unit 243 limits the guide ring inside the storage cylinder 242, so that the bearing inside the storage cylinder 242 is in a limited state when not in operation. When it is needed to output material, the material locking unit 243 can be opened. The structure is simple and easy to use.

[0112] Furthermore, the locking unit 243 can adopt a positioning pin structure that is inserted into the lower end of the storage cylinder 242.

[0113] Furthermore, such as Figure 9 The transfer mechanism 3 includes:

[0114] The fifth sliding frame 31 slides horizontally on the fifth sliding track 32;

[0115] A fourth drive unit 33, which is mounted on the fifth sliding frame 31 and has a sixth sliding frame 34 at its output end; and

[0116] The second pneumatic gripper 35 is provided in four sets and is installed on the sixth sliding frame 34.

[0117] In detail, the detector on the sixth sliding frame 34 detects the two bearings, the upper guide, and the lower guide after the output is in place. The controller drives the fourth drive unit 33 to start. The fourth drive unit 33 drives the four sets of second pneumatic grippers 35 to move down through the sixth sliding frame 34 and clamps and extracts the two bearings, the upper guide, and the lower guide respectively. After extraction, the fourth drive unit 33 resets and moves to the assembly mechanism 4 under the transmission of the fifth sliding frame 31. It then lowers and places the upper guide and the lower guide into the first mounting cylinder 418 and the second mounting cylinder 419 in the fixture respectively. Then, the two bearings are placed into the upper guide and the lower guide respectively.

[0118] Furthermore, such as Figure 10-11 The rotating assembly 41 includes:

[0119] The second turntable 411 rotates on the second mounting platform 412 and rotates intermittently in a circular motion under the drive of the fifth drive unit 413.

[0120] The fixture 414 is detachably provided in several groups along the circumferential direction of the second turntable 411. It includes a base 415 that is inserted and locked onto the second turntable 411, a mounting seat 417 that is elastically slidable on the base 415 through a second elastic unit 416, a first mounting cylinder 418 and a second mounting cylinder 419 mounted on the mounting seat 417.

[0121] Both the first mounting cylinder 418 and the second mounting cylinder 419 have clearance grooves 4141 at their upper ends and mounting posts 410 are elastically provided inside them.

[0122] In this application, by setting a floating structure fixture 414, the first mounting cylinder 418 and the second mounting cylinder 419 can automatically switch during horizontal movement, thereby realizing that the processing and positioning of the upper and lower guides can be completed under the setting of one fixture. Its structure is simple and highly adaptable.

[0123] It is worth noting that the clearance groove 4141 is designed to enable the mechanical gripper to clamp and remove the upper guide located in the first mounting cylinder 418, or to stably place the clamped upper guide into the first mounting cylinder 418, thus avoiding obstruction. It is also worth noting that the structure of the second mounting cylinder 419 is designed in the same way as that of the first mounting cylinder 418, and will not be described in detail here.

[0124] Furthermore, such as Figure 12-15 The stamping assembly 42 includes:

[0125] Translation component 421 is mounted on the second mounting platform 412. It includes a seventh sliding frame 4212 that slides vertically on a seventh sliding rail 4211, and two sets of third pneumatic grippers 4213 and fourth pneumatic grippers 4214 symmetrically arranged on the seventh sliding frame 4212. The third pneumatic grippers 4213 and fourth pneumatic grippers 4214 act on the mounting base 417 and drive the mounting base 417 to move horizontally.

[0126] Molded part 422, the molded part 422 includes an eighth sliding frame 4222 vertically sliding on an eighth sliding rail 4221, a ninth sliding rail 4223 mounted on the eighth sliding frame 4222, a ninth sliding frame 4224 slidably disposed on the ninth sliding rail 4223, a punching head 4225 and a riveting head 4226 mounted on the ninth sliding frame 4224, a sixth driving unit 4227 mounted on the eighth sliding frame 4222 and used to drive the ninth sliding frame 4224 to move horizontally; and

[0127] The first positioning component 423 is located below the second turntable 411. It includes a seventh drive unit 4231 mounted on the mounting plate, a work frame 4232 disposed at the output end of the seventh drive unit 4231 and having a work frame 4232 at its upper end that matches the lower end of the base 415, and a first support seat 4234 mounted on the work frame 4232 and horizontally slidably passing through the work frame 4232 via an eighth drive unit 4233 on the work frame 4232.

[0128] In detail, the jig 414 moves to below the molded part 422, the seventh drive unit 4231 drives the workbench 4232 to rise, and the protrusion on the upper surface of the workbench 4232 is inserted into the groove on the lower surface of the base 415. Then the eighth drive unit 4233 drives the first support seat 4234 to move horizontally to the lower end of the support part of the workbench 4232, thereby providing secondary support for the workbench 4232. Then the eighth sliding frame 4222 moves down, and the punch head 4225 punches the bearing in the upper guide multiple times to make it fully in place. Then the sixth drive unit 4227 drives the ninth sliding frame 4224 to move horizontally, and moves the riveting head 4226 to the top of the upper guide. The eighth sliding frame 4222 moves up and down again to realize the riveting of the upper end face of the upper guide. After the riveting is completed, the assembly of the upper guide and the bearing is initially completed.

[0129] Next, the seventh sliding frame 4212 moves down, and the third pneumatic gripper 4213 and the fourth pneumatic gripper 4214 come into contact with the mounting base 417, driving the mounting base 417 to move. This allows the first mounting cylinder 418 and the second mounting cylinder 419 above the mounting base 417 to alternately switch to the processing station. After moving into place, the position of the mounting base 417 is fixed, so that during the stamping process, the press head and the part can be aligned on the same axis, ensuring precise processing, smooth floating, and avoiding errors.

[0130] Next, the lower guide and bearing are initially assembled. The working principle and process are the same as the initial assembly process of the upper guide and bearing, so they will not be described in detail here.

[0131] The purpose of the first positioning component 423 is to support the fixture during the stamping process. However, the stamping pressure is relatively large. Combined with the support of the first support base 4234 for the workpiece 4232, the strong pressure is prevented from damaging the telescopic end of the seventh drive unit 4231.

[0132] Example 2

[0133] like Figure 16-17 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:

[0134] Furthermore, the output component 43 includes:

[0135] Shaping unit 431 includes a ninth drive unit 432 mounted on bracket 430, a mounting bracket 433 connected to the output end of the ninth drive unit 432, a first shaping column 434 mounted on the mounting bracket 433, and a second shaping column 435.

[0136] The second positioning component 436 is located below the second turntable 411 and includes a second support base 438 that is driven up and down by the tenth drive unit 437 and matched with the lower end of the base 415.

[0137] Furthermore, the rejection component 44 includes:

[0138] The tenth sliding frame 441 slides horizontally on the tenth sliding track 442;

[0139] The eleventh sliding frame 443 slides vertically on the eleventh sliding rail 444, and the eleventh sliding rail 444 is mounted on the tenth sliding frame 441;

[0140] The fifth pneumatic gripper 445 is mounted on the eleventh sliding frame 443 and correspondingly removes the upper guide 100 and lower guide 200 from the first mounting cylinder 418 and the second mounting cylinder 419, respectively; and

[0141] Waste cylinder 446, two sets of waste cylinder 446 are provided.

[0142] In this application, by setting the output component 43 in conjunction with the rejection component 44, the shaping unit 431 is located in the bearing in the upper guide or lower guide for downward stamping adjustment. After stamping and shaping, it is inspected. Qualified products are clamped and output by a robot arm, while unqualified products are output to the next station. The rejection component 44 clamps and outputs defective products. By using the settings of automated equipment, the product quality is stable, and its inspection and quality control are precise.

[0143] In detail, the jig 414 moves below the shaping unit 431, and the tenth drive unit 437 drives the second support seat 438 to move upward. The second support seat 438 moves below the base 415 and contacts it for support. Then, the ninth drive unit 432 drives the first shaping column 434 and the second shaping column 435 to descend. The first shaping column 434 and the second shaping column 435 act on the two mounting columns 410 respectively. The mounting columns 410 move downward. During the movement, the first shaping column 434 and the second shaping column 435 pass through the bearing and shape the bearing deformed by the riveting work. The shaping is performed by moving up and down three times. After the shaping of the bearing is completed, the detection unit checks the shaft. After the assembly is inspected and found to be in place, if the inspection is qualified, the external robot arm will clamp and output the upper and lower guides. If the inspection is unqualified, the unqualified products will be output to the rejection component 44. The eleventh sliding frame 443 moves down along the eleventh sliding track 444 to above the upper and lower guides. A detection unit is set on one side of the fifth pneumatic gripper 445. When the controller detects that there is an upper or lower guide in the first mounting cylinder 418 and the second mounting cylinder 419, the controller drives the fifth pneumatic gripper 445 to start. The fifth pneumatic gripper 445 clamps the defective product and lifts it. After lifting, it moves to above the waste cylinder 446 under the transmission of the tenth sliding frame 441, and then lowers to put the defective product into the waste cylinder 446.

[0144] Work steps

[0145] The upper guide feeding assembly 11 and the lower guide feeding assembly 12 synchronously output the upper guide 100 and the lower guide 200 one by one, respectively. At the same time, the bearing mounting mechanism 2 synchronously outputs two bearings 300 side by side. After the upper guide 100, the lower guide 200 and the two bearings 300 move to the mounting station of the transfer mechanism 3, the transfer mechanism 3 transfers them together to the assembly mechanism 4 and places them on the rotating assembly 41. At this time, the two bearings 300 are respectively placed on the upper guide 100 and the lower guide 200. The rotating assembly 41 moves to the stamping assembly 42 to complete the stamping and riveting work, and then transmits to the output assembly 43. After being detected by the detection unit, the qualified assembly is automatically output, and the unqualified assembly is transmitted to the rejection assembly 44 for output.
