Description

Technical Field

[0001] This utility model relates to the field of anti-rotation and anti-torsion arm technology, and in particular to a suspended anti-rotation and anti-torsion arm. Background Technology

[0002] In industrial settings such as machinery manufacturing, automobile assembly, and equipment maintenance, suspended adjustment equipment is often used to adapt the position of tools for tasks such as bolt tightening and component handling to meet the operational needs of different workstations and workpieces of different specifications. This type of equipment must have flexible lateral and height adjustment capabilities to ensure that the tools can be accurately aligned with the target position. Simultaneously, it must consider ease of operation and adjustment efficiency to adapt to multi-workstation switching and batch operations in industrial production. With the increasing demands for industrial automation and precision manufacturing, the shortcomings of traditional suspended adjustment equipment in terms of position adjustment flexibility, accuracy, and operational efficiency have become increasingly apparent, making it difficult to meet the requirements of modern production for rapid equipment adaptation and efficient operation.

[0003] Existing suspended adjustment devices mostly employ a mechanical structure with fixed supports and manual adjustment: lateral adjustment relies on two sets of parallel metal slide rails, with the work platform slidingly connected to the rails. Adjustment requires manual unscrewing of positioning bolts on both sides of the slide rails, manually pushing the platform along the rails, and then retightening the positioning bolts to secure it. Height adjustment is achieved through a screw drive mechanism. A vertically mounted screw is connected below the work platform, with a handwheel mounted at the top. The operator must turn the handwheel to drive the nut, moving the work platform up and down along the screw. Operators need to judge the adjustment position; there are no automated locking or drive components, relying on manual operation and experience for control.

[0004] Existing technologies suffer from cumbersome operation, low efficiency, and insufficient positioning stability during position adjustment: Lateral adjustment requires repeated manual disassembly and tightening of positioning bolts, and manual pushing of the platform is prone to adjustment deviation due to uneven resistance of the slide rails, requiring multiple subsequent calibrations; Height adjustment relies on manual rotation of the handwheel, which requires considerable manpower for heavy work tools, making operation difficult, and mechanical wear of the lead screw and nut can easily lead to height positioning errors, failing to meet the requirements of high-precision operations. Furthermore, the platform after lateral adjustment is fixed by only a single set of positioning bolts, which are prone to loosening due to vibration during equipment operation, causing platform displacement and requiring frequent shutdowns for readjustment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 - Figure 4 The embodiment provided by this utility model: a suspended anti-rotation and anti-torsion arm, including a suspension point 1, and an adjustable component is provided on one side of the outer wall of the suspension point 1;

[0028] The adjustable assembly includes four linear guide rails 2. A suspension point 1 is fixedly connected to the upper surface of two of the linear guide rails 2 on one side of its outer wall. The suspension point 1 provides a suspension fulcrum for the entire device and can be connected to an external suspension structure to ensure stable suspension. A connecting rod 26 is fixedly connected to one side of the outer wall of the other two linear guide rails 2. Two trolleys 3 are slidably connected to the upper surface of the other two linear guide rails 2. The linear guide rails 2 provide horizontal sliding tracks 14 for the trolleys 3, enabling lateral position adjustment of the device. The trolleys 3 can slide smoothly along the linear guide rails 2 to meet the lateral position requirements under different working conditions. Two mounting plates 28 are fixedly connected to both sides of the outer wall of the two trolleys 3. Screws 29 are threaded onto one side of the outer wall of the mounting plates 28. Two round holes 32 are opened inside the trolleys 3. An elastic sleeve 30 is fixedly connected to one side of the outer wall of the trolley 3. A locking block 27 is fixedly connected to one side of the outer wall of the elastic sleeve 30. When the trolley 3 slides to the desired position, the elastic sleeve 30 undergoes elastic deformation, causing the locking block 27 to engage with the pre-set position on the linear guide rail 2. The slot is designed to temporarily position the trolley 3. The bottom of the other two trolleys 3 is fixedly connected to the moving platform 4, which is a load-bearing component. The lower surface of the moving platform 4 is fixedly connected to the pneumatic toothed clutch 5. The pneumatic toothed clutch 5 controls the connection state between the moving platform 4 and the fixed adjuster 22. When air is supplied, it engages and locks the position. When air is cut off, the equipment can be adjusted in position. The lower surface of the pneumatic toothed clutch 5 is fixedly connected to the fixed adjuster 22. The fixed adjuster 22 serves as a connector and housing and is used to install and fix the lifting anti-torsion arm 8. The lifting anti-torsion arm 8 is fixedly connected to the inner wall of the fixed adjuster 22. The inner telescopic rod 24 is slidably connected inside the lifting anti-torsion arm 8. The fixed adjuster 22 is used to fix the lifting anti-torsion arm 8. The bottom of the inner telescopic rod 24 is fixedly connected to the sliding rail 14. The outer wall of the sliding rail 14 is fixedly connected to the anti-heeling rotating seat 13. The outer wall of the inner telescopic rod 24 is fixedly connected to the lifting and retracting cylinder 12. The lifting and retracting cylinder 12 can realize the extension and retraction of the inner telescopic rod 24 along the lifting anti-torsion arm 8.

[0029] Specifically, when the position of the equipment needs to be adjusted, the pneumatic toothed clutch 5 is driven to control the connection between the moving platform 4 and the fixed adjuster 22. When air is supplied, the position can be locked; when air is cut off, the equipment can be adjusted in position. The trolley 3 slides along the linear guide rail 2, and after reaching the position, the elastic sleeve 30 drives the locking block 27 to lock. When adjusting the height of the equipment, the air supply to the pneumatic toothed clutch 5 is cut off, causing its internal teeth to separate and releasing the lock on the lifting anti-torsion arm 8. The lifting cylinder 12 drives the inner telescopic rod 24 to slide up and down along the lifting anti-torsion arm 8. After adjusting to the target height, the pneumatic toothed clutch 5 is activated, and the fixed adjuster 22 is locked again. The anti-rotation seat 13 can limit the rotation of the inner telescopic rod 24, playing an anti-rotation role, thereby realizing the adjustment of the equipment position.

[0030] Reference Figure 1 - Figure 7A fastening bolt 321 is fixedly connected to the middle of the outer wall of lifting point 1. A fixing plate 19 is fixedly connected to the bottom of fastening bolt 321. The locking force of fastening bolt 321 rigidly connects fixing plate 19 to lifting point 1. A linear guide rail 2 is fixedly connected to the lower surface of fixing plate 19. Fastening bolt 20 is threaded inside fixing plate 19. Two support plates 31 are fixedly connected to the lower surface of lifting point 1. Fastening bolt 17 is fixedly connected to the lower surface of support plate 31. Nut 18 is threaded on the outer wall of fastening bolt 17. Two locking blocks 16 are fixedly connected to one side of the outer wall of lifting point 1. Locking blocks 16 can cooperate with the positioning pins of the external suspension structure to realize the quick locking of the suspension position of lifting point 1 and prevent the overall device from shifting. A spring balancer 6 is fixedly connected to one side of the outer wall of lifting anti-torsion arm 8. A hook 15 is fixedly connected to the upper surface of spring balancer 6. Spring balancer 6 is connected to lifting anti-torsion arm 8 through hook 15, which has a buffering effect and reduces the operating load. A safety fall arrestor 7 is fixedly connected to prevent the device from falling accidentally. One end of the telescopic cylinder 12 is fixedly connected to one side of the outer wall of the anti-heel rotating seat 13. One end of the anti-heel rotating seat 13 is fixedly connected to a mounting plate 25. The anti-heel rotating seat 13 cooperates with the sliding rail 14 to limit the rotation of the inner telescopic rod 24 during the telescopic process, ensuring the stability of the tightening sleeve 11. A fixing plate 23 is fixedly connected to one side of the outer wall of the inner telescopic rod 24. A tightening shaft 9 is fixedly connected to one side of the outer wall of the fixing plate 23. A tightening sleeve 11 is fixedly connected to the bottom of the tightening shaft 9. The tightening shaft 9 is used by rotating with the lower tightening sleeve 11. An auxiliary handle 10 is fixedly connected to one side of the outer wall of the fixing plate 23. One end of the fixing adjuster 22 is fixedly connected to the lower surface of the pneumatic toothed clutch 5. The position is fixed by the mounting plate 28 and screws 29. The elastic sleeve 30 generates radial contraction under the action of pre-tightening force, which drives the locking block 27 to be embedded in the positioning groove on the side of the linear guide rail 2, so as to realize the mechanical positioning and locking of the trolley 3.

[0031] Specifically, when the equipment is in use, the two fixing plates 19 are first clamped to the outer wall of the linear guide rail 2 by the fastening bolts 20 of the suspension point 1. The locking block 16 is used to fix the connected object. The trolley 3 slides on the linear guide rail 2 to adjust the position of the equipment. The mounting plate 28 is clamped to the outer wall of the linear guide rail 2 by tightening the screws 29. The locking block 27 is inserted into the elastic sleeve 30 to realize the stable operation of the trolley 3. The spring balancer 6 can be connected to the lifting anti-torsion arm 8 by means of the hook 15 to offset part of the gravity. The safety fall arrestor 7 is used to prevent the parts from falling accidentally, thereby realizing the stable operation of the equipment.

[0032] Working principle: First, the entire device is securely suspended from external support structures such as workshop beams by means of suspension point 1 in the suspension assembly and related components such as fixing plate 19 and fastening bolts. When lateral adjustment is required, the operator first manually loosens the two screws 29 on mounting plate 28. At this time, the locking state between trolley 3 and linear guide rail 2 is released, and the two trolleys 3 can slide freely along the linear guide rail 2, thereby driving the entire lifting assembly to move laterally. During this process, the cooperation between elastic sleeve 30 and locking block 27 provides a certain damping feel and temporary positioning function to prevent accidental movement. After moving to the target position, the operator tightens the two screws 29, and the mounting plate 28 is firmly fixed to the linear guide rail 2 by the squeezing force, thus completing the reliable locking of the lateral position.

[0033] When height adjustment is required, firstly, the air supply to the pneumatic toothed clutch 5 is cut off, causing its internal teeth to disengage and releasing the lock on the lifting anti-torsion arm 8; at this time, the lifting assembly is in an adjustable state. Subsequently, the lifting cylinder 12 is activated, and the cylinder drives the inner telescopic rod 24 to slide smoothly up and down in the inner hole of the lifting anti-torsion arm 8. During this process, since the inner hole of the lifting anti-torsion arm 8 and the outer contour of the inner telescopic rod 24 are both non-circular, their sliding engagement effectively prevents the inner telescopic rod 24 from rotating, thus playing an anti-rotation role; after adjusting to the target height, air is supplied to the pneumatic toothed clutch 5, causing its internal teeth to re-engage, firmly locking the lifting anti-torsion arm 8 to the upper moving platform 4, completing the height positioning; in this embodiment, the fixed adjuster 22 serves as a connector and housing, used to install and fix the lifting anti-torsion arm 8, and provides a mounting base for the pneumatic toothed clutch 5; throughout the entire use, the spring balancer 6 is connected to the lifting anti-torsion arm 8 through the hook 15, and its elasticity can offset part of the weight of the lifting assembly, making the adjustment operation more effortless. As a redundant protection, the safety fall arrestor 7 can lock instantly in the event of an unexpected failure of the suspension system, preventing the equipment from falling and ensuring the safety of personnel and equipment.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
