For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0051] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0052] This embodiment relates to a suspension tie rod assembly device, which helps to improve the assembly efficiency of the tie rod assembly and shorten the production cycle.

[0053] In terms of overall composition, Figure 1 and Figure 2 As shown, the suspension tie rod assembly device of this embodiment includes a sleeve feeding mechanism 1, a diameter reduction and oiling mechanism 2, a press-fitting mechanism 3, a coding and detecting mechanism 4, and a loading and unloading mechanism 5, which are arranged in sequence.

[0054] Among them, the sleeve feeding mechanism 1 is used to transport multiple sleeves to preset positions in sequence. The diameter reduction and oiling mechanism 2 includes a diameter reduction portion 21 and an oiling portion 22. The diameter reduction portion 21 is used to reduce the diameter of the sleeves transported by the sleeve feeding mechanism 1, and the oiling portion 22 is used to oil the sleeves after diameter reduction. The pressing mechanism 3 is used to press the oiled sleeves and the pull rods into a pull rod assembly. The coding and detection mechanism 4 includes a coding unit 41 and a code scanning unit 42. The coding unit 41 is used to set a product code on the pull rod assembly, and the code scanning unit 42 is used to identify the product code. The loading and unloading mechanism 5 includes a pull rod loading unit 51 and an assembly unloading unit 52. The pull rod loading unit 51 is used to transport the pull rod to be pressed into the pressing mechanism 3, and the assembly unloading unit 52 is used to unload the pull rod assembly.

[0055] At this time, the above structure can realize the production processes of loading, shrinking and oiling of the sleeve, as well as the pressing, coding detection and loading and unloading of the sleeve and pull rod. This can help improve the assembly efficiency of the pull rod assembly, shorten the production cycle, and also help improve product quality.

[0056] Based on the above overall structure, in detail, the sleeve feeding mechanism 1, the diameter reduction oiling mechanism 2, the pressing mechanism 3, the coding detection mechanism 4 and the loading and unloading mechanism 5 of this embodiment are sequentially arranged on a fixed base 100, wherein the fixed base 100 can be, for example, the ground or a frame fixed relative to the ground. As a preferred embodiment, Figure 3 and Figure 4 As shown, combined with Figure 1 and Figure 2 The sleeve loading device of this embodiment includes a first driving device, a lifting plate 11 connected to the first driving device, and a conveying portion 12 provided downstream of the lifting plate 11. The first driving device is used to drive the lifting plate 11 to move up and down. The lifting plate 11 is used to carry multiple sleeves arranged side by side. The conveying portion 12 is used to receive the sleeves conveyed by the lifting plate 11.

[0057] In a specific implementation, the first drive device can be, for example, an elevator or a modular lifting unit. The conveying portion 12 includes a conveyor belt, which is wound around a driving roller and a driven roller. The motor drives the driving roller to rotate, thereby driving the conveyor belt. To ensure the positional accuracy of the conveyed sleeves, a shaping groove 13 is also provided downstream of the conveyor belt. The width of the shaping groove 13 is slightly larger than the outer diameter of the sleeves. While ensuring smooth conveyance of the sleeves, the gap between the groove wall of the shaping groove 13 and the outer circumference of the sleeves should be as small as possible. This ensures that multiple sleeves can be arranged in close proximity and side by side.

[0058] This embodiment adopts the above-mentioned sleeve loading device, which is beneficial to improving the loading efficiency of the sleeve, and by increasing the width of the lifting plate 11, it can be suitable for loading sleeves of different diameters, which is beneficial to improving the versatility of the sleeve loading device, so that it can be compatible with the assembly of different types of pull rod products.

[0059] The reducing part 21 in the reducing and oiling mechanism 2 of this embodiment preferably adopts a sinking reducing machine, and the specific structure of the reducing machine can refer to the existing structure. As a preferred embodiment, in this embodiment, a detection unit is provided between the reducing part 21 and the oiling part 22, and the detection unit includes a first detection unit 23 and a second detection unit 24. Among them, the first detection unit 23 is used to detect at least one of the radial dimension and the height dimension of the sleeve after the reduction, and the second detection unit 24 is used to perform load detection on the sleeve after the reduction. In this way, the first detection unit 23 is set up to detect at least one of the radial dimension and the height dimension of the sleeve after the reduction, which is beneficial to improve the preparation quality of the sleeve, effectively prevent the outflow of defective products, and thus help improve the quality of the pull rod assembly. The second detection unit 24 is set up to be able to perform load detection on the sleeve after the reduction, and is used to detect the hardness of the rubber in the sleeve.

[0060] In specific implementation, the first detection unit 23 of this embodiment includes a laser displacement sensor. By setting the number of laser displacement sensors, each laser displacement sensor is used to detect the radial dimension and height dimension of the sleeve. The second detection unit 24 of this embodiment includes a load detection assembly, which includes a pressure sensor, a displacement sensor, etc. This load detection assembly is used to detect the hardness of the rubber compound in the sleeve by detecting the force value after the product is compressed to a certain displacement. This can promptly detect whether the rubber compound is used incorrectly and facilitate online inspection of the sleeve.

[0061] It should be noted that, in addition to both the first detection unit 23 and the second detection unit 24, the detection unit of this embodiment may also be provided with only the first detection unit 23, or may also be provided with only the second detection unit 24. In addition, it should also be noted that, in addition to detecting both the radial dimension and the height dimension of the sleeve, the first detection unit 23 may also be provided with only the radial dimension, or may also be provided with only the height dimension of the sleeve, which is also feasible.

[0062] In addition, as a preferred embodiment, in this embodiment, a NG unloading unit is also provided downstream of the inspection unit. This NG unloading unit is used to unload sleeves that fail the shrinking process. Specifically, a first NG unloading unit is provided downstream of the first inspection unit 23. This first NG unloading unit includes a first guide trough 25, at the end of which is a first defective product bin 27. Shrinkage sleeves are considered defective if at least one of their height or radial dimensions fails to meet the requirements. After inspection by the first inspection unit 23, the unqualified sleeves are transported along the first guide trough 25 into the first defective product bin 27.

[0063] Downstream of the second inspection unit 24 is a second NG unloading unit, comprising a second guide chute 26, at the end of which is a second defective bin 28. Even if the reduced sleeves meet the required height and radial dimensions, there is a risk of using the wrong sleeve compound due to failure to meet the load test requirements. In this case, sleeves that fail the load test are considered defective. After inspection by the second inspection unit 24, the unqualified sleeves are conveyed along the second guide chute 26 into the second defective bin 28.

[0064] As a further preferred embodiment, Figures 3 to 7 As shown, the diameter reduction and oiling mechanism 2 of this embodiment also includes a first workpiece transfer mechanism 201 and a second workpiece transfer mechanism 202. The first workpiece transfer mechanism 201 is used to transfer the sleeve between the preset position and the diameter reduction portion 21, while the second workpiece transfer mechanism 202 is used to transfer the sleeve between the diameter reduction portion 21, the detection unit, and the oiling portion 22. This enables automated circulation of the sleeves and improves sleeve production efficiency.

[0065] For specific structure, see Figures 3 to 6As shown, the first workpiece transfer mechanism 201 includes a first moving assembly 2011 and a first gripping portion 2012, as well as a second moving assembly 2013 and a second gripping portion 2014. The first gripping portion 2012 is connected to the first moving assembly 2011, and the second gripping portion 2014 is connected to the second moving assembly 2013. Furthermore, the first moving assembly 2011 can drive the first gripping portion 2012 to transfer a sleeve at a preset position to the first transfer mechanism 10 in the diameter reduction and oiling mechanism 2. The second moving assembly 2013 can drive the second gripping portion 2014 to sequentially transfer the sleeve between the first transfer mechanism 10, the diameter reduction portion 21, and the second transfer mechanism 20 in the diameter reduction and oiling mechanism 2. Thus, the first workpiece transfer mechanism 201 can improve the sleeve movement efficiency and shorten the sleeve production cycle.

[0066] Specifically, the first moving component 2011 can drive the first grabbing portion 2012 along Figure 3 The first direction shown in FIG. 2 is moved to the first transfer mechanism 10, and the second moving component 2013 can drive the second grasping portion 2014 along Figure 3 The second direction shown in the figure sequentially transfers the sleeve between the first transfer mechanism 10, the reduced diameter portion 21 and the second transfer mechanism 20.

[0067] The second workpiece transfer mechanism 202 of this embodiment is a preferred embodiment. In terms of specific structure, Figure 3 、 Figure 4 and Figure 7 As shown, the second workpiece transfer mechanism 202 includes a transverse moving assembly 2021 and a plurality of third gripping portions 2022 disposed on the transverse moving assembly 2021. Furthermore, the transverse moving assembly 2021 is capable of driving the plurality of third gripping portions 2022 to move between a first workstation and a second workstation. At the first workstation, the plurality of third gripping portions 2022 are disposed in a one-to-one correspondence with the second transfer mechanism 20, the detection unit, and the oiling portion 22. At the second workstation, the plurality of third gripping portions 2022 are disposed in a one-to-one correspondence with the detection unit, the oiling portion 22, and the third transfer mechanism 30 located downstream of the oiling portion 22.

[0068] Specifically, the lateral moving component 2021 can drive the third gripping portion 2022 along Figure 3 , the first direction is shown as movement between the first and second workstations. In this embodiment, based on the premise that the detection unit includes the first detection unit 23 and the second detection unit 24, the lateral movement assembly 2021 is provided with four third gripping parts 2022. When in the first workstation, the four third gripping parts 2022 are provided in a one-to-one correspondence with the second transfer mechanism 20, the first detection unit 23, the second detection unit 24, and the oiling part 22. When in the second workstation, the four third gripping parts 2022 are provided in a one-to-one correspondence with the first detection unit 23, the second detection unit 24, the oiling part 22, and the third transfer mechanism 30.

[0069] In this case, the transverse movement assembly and the plurality of third gripping portions 2022 can also improve the transfer efficiency of the sleeve and shorten the sleeve production cycle. Furthermore, the coordination between the first workpiece transfer mechanism 201 and the second workpiece transfer mechanism 202 can further improve the transfer efficiency of the sleeve and further shorten the sleeve production cycle.

[0070] It should be noted that the power sources of the first moving component 2011, the second moving component 2013 and the transverse moving component can be linear drive devices such as linear modules, cylinders or oil cylinders, and the first grasping part 2012, the second grasping part 2014 and the third grasping part 2022 preferably use clamping cylinders.

[0071] The oiling portion 22 of this embodiment includes an oiling roller. When a qualified sleeve is transferred to the oiling portion 22, the outer peripheral surface of the sleeve is tangentially arranged to the outer peripheral surface of the oiling roller. The sleeve is sleeved on the positioning shaft, and the positioning shaft is pre-coated with oil. At this time, the rotation of the oiling roller drives the rotation of the sleeve, and the outer peripheral surface of the sleeve is also oiled.

[0072] As a preferred embodiment, Figure 9 As shown, the press-fitting mechanism 3 of this embodiment is provided with a third workpiece transfer mechanism 301, which is used to transfer the sleeves between the oiling portion 22 and the press-fitting mechanism 3. The provision of the third workpiece transfer mechanism 301 facilitates the transfer of the oiled sleeves to the press-fitting mechanism 3, thereby improving the degree of automation of the sleeve transfer and the sleeve circulation efficiency.

[0073] Specifically, the third workpiece transfer mechanism 301 includes a third moving component 3011, and a gripping unit 3012 connected to the third moving component 3011. The gripping unit 3012 has two fourth gripping parts arranged at intervals, and the two fourth gripping parts correspond to the two ends of the pull rod respectively, and the shaft sleeves gripped by the two fourth gripping parts can be driven by the third moving component 3011 to move to the shaft sleeve holes at both ends of the pull rod.

[0074] Also as a preferred embodiment, Figures 9 to 11 As shown, the press-fitting mechanism 3 of this embodiment includes a press-fitting drive unit 300, a first fixture 31 connected to the press-fitting drive unit 300, and a second fixture 32 for securing the tie rod. The first fixture 31 is provided with a pressing head 311. The pressing head 311 is driven by the press-fitting drive unit 300 to press-fit the delivered sleeve into the sleeve hole of the tie rod. The press-fitting drive unit 300 is, for example, a pressure cylinder. The first fixture 31 is connected to the power output end of the pressure cylinder and can be driven by the pressure cylinder to move closer to or away from the second fixture 32. The second fixture 32 is fixed to the press-fitting platform and is used to secure the tie rod.

[0075] When the pull rod to be pressed is fixed on the second tooling frame 32, the third moving component 3011 is moved to transport the sleeve on the gripping unit 3012 to the sleeve hole of the pull rod to be pressed, and then the pressing drive unit 300 is driven to move the first tooling frame 31 and drive the pressing head 311 to move, so that the pressing head 311 presses the two sleeves into the sleeve holes at both ends of the pull rod.

[0076] Combine Figure 10 and Figure 11 As shown, in this embodiment, the press head 311 is detachably connected to the first fixture 31. This arrangement facilitates quick replacement of the press head 311, thereby facilitating the press-fitting of sleeves for different tie rod products. In a specific implementation, the press head 311 is preferably connected to the first fixture 31 using, for example, a quick-release pin 312.

[0077] In addition, as a further preferred embodiment, in this embodiment, a connecting frame 320 is rotatably provided on the second fixture frame 32, and a plurality of tie rod fixing frames 321 are provided on the connecting frame 320. Each tie rod fixing frame 321 is used to fix a tie rod, and the plurality of tie rod fixing frames 321 can be rotated to the bottom of the pressing head 311 in sequence. At this time, when one of the tie rod fixing frames 321 is in the press-fitting station for press-fitting, the other tie rod fixing frames 321 are in the preparation state. After the tie rod and sleeve on one of the tie rod fixing frames 321 are press-fitted, the next tie rod fixing frame 321 is rotated to the press-fitting station for press-fitting, and the tie rod assembly that has been press-fitted can be unloaded by the robot 50, thereby shortening the press-fitting cycle of the tie rod assembly and further improving the efficiency of tie rod assembly assembly.

[0078] In addition, in this embodiment, a positioning column 3101 is also provided on the first tooling frame 31, and correspondingly, a positioning hole 3201 for inserting the positioning column 3101 is provided on the second tooling frame 32. The positioning and cooperation between the positioning column 3101 and the positioning hole 3201 is conducive to ensuring the relative position of the first tooling frame 31 and the second tooling frame 32, thereby facilitating the pressure head 311 to press the sleeve into the sleeve hole of the pull rod more accurately.

[0079] To facilitate the installation and disassembly of the tie rod fixing frame 321 on the connecting frame 320, in this embodiment, a positioning pin 3211 is provided on the connecting frame 320 to position the tie rod fixing frame 321. The positioning pin 3211 can be inserted into the positioning hole on the tie rod fixing frame 321. At the same time, the tie rod fixing frame 321 is installed on the connecting frame 320 by sequentially passing through the locking screw 3212 of the tie rod fixing frame 321 and the connecting frame 320. In this way, the tie rod fixing frame 321 can be better maintained on the connecting frame 320, ensuring the accuracy of the position of the tie rod fixing frame 321 on the connecting frame 320, and also facilitating the disassembly and replacement of the tie rod fixing frame 321, and also helping to improve the quality of the shaft sleeve press-fitting.

The coding unit 41 includes a laser coding unit 411 and an automatic coding unit 412. The laser coding unit 411 is used to engrave the product code on the pull rod assembly, while the automatic coding unit 412 is used to affix the product code to the pull rod assembly. Using the laser coding unit 411 and the automatic coding unit 412 to set the product code on the pull rod assembly facilitates product identification and traceability.

[0081] During specific implementation, the laser coding unit 411 can use existing laser coding equipment to engrave the product code on the outer surface of the pull rod assembly through a laser emitter. The automatic coding unit 412 includes a label reel assembly 4121, a label peeling assembly 4122, a label adsorption assembly 4123 and a drive assembly 4124, wherein the label reel assembly 4121 is used to unwind the roll material and rewind the film after peeling the label. The label peeling assembly 4122 is used to peel the label off the roll material. The label adsorption assembly 4123 is connected to the power output end of the drive assembly 4124, and the label adsorption assembly 4123 is driven by the drive assembly 4124 to stick the adsorbed label on the pull rod assembly.

[0082] In addition, the code scanning unit 42 can be set on the laser coding device or at other locations to be able to scan the product code set on the pull rod assembly, wherein the code scanning unit 42 can realize barcode, QR code and coding content error recognition, thereby realizing online detection.

[0083] It is worth noting that the aforementioned adsorption component preferably uses vacuum adsorption to fix the peeled label, which is also the product code. In addition, it is also worth mentioning that in addition to being equipped with both the laser coding unit 411 and the automatic coding unit 412, the coding unit 41 of this embodiment can also be equipped with only the laser coding unit 411 or only the automatic coding unit 412. Such an arrangement is also possible.

[0084] In addition, as a preferred embodiment, the loading and unloading mechanism 5 of this embodiment includes a rod loading unit 51 and a component unloading unit 52, wherein the loading unit and the unloading unit are arranged vertically, which is conducive to saving space. The loading unit and the unloading unit are thus transported in the form of rollers. The rods and rod assemblies to be pressed are respectively loaded into the material box 200. Moreover, the material box 200 with the rods is transported to one end near the coding and detection mechanism 4 by the loading unit, and the material box 200 with the rod assemblies is transported from one end near the coding and detection mechanism 4 to the other end by the unloading unit.

[0085] In addition to the rod loading unit 51 and the component unloading unit 52, the loading and unloading mechanism 5 of this embodiment also includes a robot 50, which is used to transfer rods or rod components between the rod loading unit 51, the press-fitting mechanism 3, the coding and detection mechanism 4, and the component unloading unit 52. The provision of the robot 50 is conducive to improving the automated flow of rods and the efficiency of loading and unloading. By replacing the tooling on the robot 50 and the tooling in the press-fitting mechanism 3, it is also conducive to the production of products of the same type with different specifications, thereby improving the reuse rate of equipment.

[0086] The suspension tie rod assembly device of this embodiment can perform the production processes of bushing loading, diameter reduction, and oiling, as well as the press-fitting, coding, inspection, and loading and unloading of the bushing and tie rod. This improves tie rod assembly efficiency, shortens production cycles, and improves product quality. Furthermore, it can facilitate switching between different products, making it compatible with a wider range of product types, resulting in a high equipment reuse rate and greater versatility.
