Description

Technical Field

[0002] During the assembly of the engine and motor, the motor rotor and motor stator are generally installed sequentially, and the relative installation positions of the motor stator and motor rotor must be ensured. That is, a certain air gap needs to be reserved between the motor rotor and motor stator. When the engine parts leave the factory, the entire engine needs to be assembled.

[0003] When producing the 1.5T model, the first step is to use an automatic unloosening robot to loosen all the bolts of the retainer inside the cylinder head. During the loosening process, some bolts will not be completely loosened. Therefore, during subsequent disassembly and assembly, workers still need to manually loosen each bolt completely before removing it. This is both labor-intensive and time-consuming, and urgently needs to be improved. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] according to Figure 1 , 2 As shown in Figures 3, 4, 5, and 6, this embodiment proposes a cage bolt material taking assembly, including an upper base plate 1, a lower base plate 7 on one side of the upper base plate 1, and multiple connecting posts 3 between the lower base plate 7 and the upper base plate 1. The left and right ends of the connecting posts 3 are fixedly connected to the upper base plate 1 and the lower base plate 7, respectively.

[0027] Multiple rotating gripping mechanisms 2 are placed on the side of the upper base plate 1 near the lower base plate 7 for picking up and putting down bolts. The rotating gripping mechanisms 2 penetrate the lower base plate 7.

[0028] Coupling A and coupling B are located at the connection points between the rotary gripping mechanism 2 and the upper base plate 1, and between the rotary gripping mechanism 2 and the lower base plate 7, and are used to support the rotation and axial movement of the rotary gripping mechanism 2.

[0029] The power unit, located on the outside of the upper base plate 1, is used to control the rotation of each rotating gripping mechanism 2.

[0030] The upper base plate 1 and the lower base plate 7 are fixed together by the connecting column 3 to form a frame-type main structure. The rotating gripping mechanism 2 is designed to pass through the lower base plate 7 and mainly plays the role of gripping and releasing bolts. The connecting shaft A and connecting shaft B ensure that the rotating gripping mechanism 2 can rotate flexibly on the main structure to adapt to the bolt angle and move axially to adapt to the gripping distance. The power component provides rotational power for the rotating gripping mechanism 2, thereby realizing batch synchronous rotating bolt operation, greatly improving work efficiency and having strong versatility.

[0031] Regarding the rotary gripping mechanism:

[0032] The rotating gripping mechanism 2 includes a guide shaft 21, a conductive copper seat 29 is sleeved on the outside of the guide shaft 21, the conductive copper seat 29 is fixedly connected to the guide shaft 21, an electromagnet 22 is provided at the end of the guide shaft 21 away from the upper base plate 1, a suction cup 23 is provided on the outside of the electromagnet 22, the guide shaft 21 and the suction cup 23 are both fixedly connected to the electromagnet 22, a carbon brush assembly 8 is provided on the side of the lower base plate 7 away from the upper base plate 1, which is magnetically engaged with the conductive copper seat 29, and a spring return structure is provided at the end of the guide shaft 21 near the upper base plate 1.

[0033] The guide shaft 21 drives the electromagnet 22 and the suction cup 23 to rotate and move axially synchronously. The carbon brush assembly 8 contacts the conductive copper base 29 to conduct electricity, powering the electromagnet 22 to generate magnetic force. The suction cup 23 uses magnetic force to attract the bolt to achieve gripping. During gripping, the guide shaft 21 is subjected to a reaction force to move axially and compress the spring reset structure. When releasing the material, the power is cut off, and the spring reset structure releases the elastic force to drive the guide shaft 21 to reset, completing the bolt release. The bolt is quickly gripped and released through electromagnetic adsorption, eliminating the need for complex opening and closing actions of mechanical clamping, and resulting in a faster response speed.

[0034] Regarding carbon brush assemblies:

[0035] The carbon brush assembly 8 includes two carbon brush holders 81, which are placed between each conductive copper base 29. The carbon brush holders 81 are fixedly connected to the carbon brush assembly 8. Multiple carbon brushes 82 are provided on the left and right sides of the carbon brush holders 81. The carbon brushes 82 have mounting grooves on their inner sides, and conductive copper sheets 83 are provided in the mounting grooves.

[0036] The current is transmitted to the carbon brush 82 through the conductive copper sheet 83, and then conducted to the electromagnet 22 through the contact between the carbon brush 82 and the conductive copper base 29, so as to achieve continuous power supply. The design of the double carbon brush base 81 and the multiple carbon brushes 82 increases the conductive contact area and ensures stable current transmission.

[0037] It is worth explaining in detail that the coupling A includes a first bearing ring 24, which is sleeved on the outside of the guide shaft 21 and rotatably connected to the upper base plate 1. The upper end of the guide shaft 21 passes through the upper base plate 1 and the first bearing ring 24. The upper base plate 1 and the first bearing ring 24 are provided with through holes that allow the guide shaft 21 to rotate and move axially.

[0038] The coupling B includes a second bearing ring 27, which is sleeved on the outside of the guide shaft 21 and rotatably connected to the lower base plate 7. The guide shaft 21 passes through the second bearing ring 27 and the lower base plate 7. The second bearing ring 27 and the lower base plate 7 are provided with through holes that allow the guide shaft 21 to rotate and move axially.

[0039] The double bearing ring supports the rotation limit, which can effectively improve the rotation accuracy and stability of the guide shaft 21 and avoid shaking during rotation, which would cause the bolt gripping to deviate. The through hole setting can take into account both the rotation and axial movement of the guide shaft 21, making the guide shaft 21 move more flexibly and adapt to different gripping depth requirements.

[0040] Regarding the powertrain components:

[0041] The power assembly includes a motor 4, a drive gear 5, and multiple driven gears 6. The motor 4 is fixedly mounted on the upper end of the upper base plate 1, the drive gear 5 is rotatably mounted on the lower end of the upper base plate 1, the driven gears 6 are fixedly connected to the first bearing ring 24, the drive gear 5 is placed between each driven gear 6 and meshes with each driven gear 6, the output end of the motor 4 is fixedly connected to the drive gear 5, the driven gears 6 are sleeved on the outer side of each guide shaft 21, and a positioning pin is fixedly mounted on the inner side of the driven gear 6. The positioning pin is slidably connected to the key guide groove 211 opened on the outer side of the guide shaft 21.

[0042] After the motor 4 starts, it drives the drive gear 5 to rotate. The drive gear 5 drives multiple driven gears 6 to rotate synchronously through gear meshing. The positioning pin on the inner side of the driven gear 6 is embedded in the key guide groove 211 of the guide shaft 21, which transmits the rotational power to the guide shaft 21 and drives the guide shaft 21 to rotate. The positioning pin can slide along the key guide groove 211 without affecting the axial movement of the guide shaft 21.

[0043] Specifically, the spring reset structure includes a compression spring 25, a flat washer 26, and a retaining ring 28. The compression spring 25, the flat washer 26, and the retaining ring 28 are sleeved on the outside of the guide shaft 21. The retaining ring 28 is fixedly connected to the guide shaft 21. The flat washer 26 is fixedly disposed at the lower end of the driven gear 6. The compression spring 25 is fixedly disposed between the flat washer 26 and the retaining ring 28.

[0044] When the guide shaft 21 moves axially to grab the bolt, it drives the anti-reverse ring 28 to move synchronously, compressing the spring 25 between the flat washer 26 and the anti-reverse ring 28. The spring 25 deforms and stores elastic force. When the material is released, the electromagnet 22 is de-energized, and the spring 25 releases its elastic force to push the anti-reverse ring 28 to reset, thereby driving the guide shaft 21, electromagnet 22, and suction cup 23 back to their initial positions.

[0045] How this application works:

[0046] When picking up materials, the motor 4 starts and drives the drive gear 5 to rotate. The drive gear 5 drives multiple meshing driven gears 6 to rotate synchronously. The driven gears 6 cooperate with the key guide groove 211 of the guide shaft 21 through the inner positioning pin, driving the guide shaft 21 to rotate. At the same time, the conductive copper sheet 83 of the carbon brush assembly 8 contacts the conductive copper seat 29 to conduct electricity, powering the electromagnet 22 to generate magnetic force, which is used to attract the bolt through the suction cup 23. During the attraction process, the guide shaft 21 moves axially under the reaction force of the bolt. The compression spring 25 stores the elastic force, and the first bearing ring 24 and the second bearing ring 27 ensure that the rotation and axial movement of the guide shaft 21 are smooth.

[0047] When feeding, the power supply to the electromagnet 22 is cut off, the magnetic force disappears, the spring 25 releases its elastic force to push the guide shaft 21 to reset, and at the same time the motor 4 stops working, the guide shaft 21 stops rotating, and the bolt is released; the motor 4 can control multiple rotating gripping mechanisms 2 to move synchronously through the cooperation of the drive gear 5 and the driven gear 6, so as to realize batch picking and placing of bolts and improve work efficiency.
