Description

Technical Field

[0001] This utility model relates to the field of steel leaf spring transfer and processing, and in particular to a gripping structure for steel leaf spring transfer and processing. Background Technology

[0002] Leaf spring transfer processing refers to a series of operations during the manufacturing process of leaf springs, involving the transport of the springs from one processing stage or storage location to another, ensuring accurate, stable, and safe movement during the transfer. This process involves a specialized gripping structure, achieved through carefully designed mechanical grippers, robotic arms, and connecting bases. The mechanical grippers precisely hold the leaf springs according to their shape and size, the robotic arms provide flexible displacement and positioning functions, and the connecting base ensures a stable connection between the entire gripping structure and the transfer equipment. This efficiently completes the transfer of leaf springs between different processing stages, ensuring production continuity and product quality.

[0003] However, the current gripping structure usually cannot lubricate itself during operation, requiring staff to lubricate it regularly. This results in frequent maintenance and affects its lifespan. Furthermore, the current gripping structure is inconvenient to disassemble and install, making replacement time-consuming and laborious for staff.

[0004] In response to this technical problem, this application proposes a gripping structure for the transfer and processing of leaf springs. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a gripping structure for the transfer and processing of leaf springs. The aim is to enable the gripping structure to self-lubricate during operation, reducing the frequency of maintenance by workers and increasing its service life. Furthermore, the gripping structure is easy to disassemble and install, facilitating replacement by workers.

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

[0007] A gripping structure for transferring and processing leaf springs includes a mounting base, an insert plate inserted into the bottom side of the mounting base, and the mounting base and the insert plate connected by a snap-fit ​​assembly for removing the insert plate from the mounting base. A fixing tube is fixedly connected to the bottom side of the insert plate, and a gripper for gripping the leaf spring is connected inside the fixing tube through a drive assembly. The drive assembly opens and closes the gripper. A lubrication assembly for lubricating the gripper is provided on the outer wall of the fixing tube.

[0008] Furthermore, the buckle assembly includes two grooves formed on the bottom side of the insert plate, a telescopic rod is fixedly connected inside the groove, and an insert rod is fixedly connected to the end of the telescopic rod, the insert rod being inserted into the interior of the mounting base.

[0009] Furthermore, a first spring is sleeved on the outer wall of the telescopic rod, one end of the first spring is connected to one side inside the groove, and the other end of the first spring is connected to one end of the insertion rod. A lever is fixedly connected to the outer wall of the insertion rod.

[0010] Furthermore, the driving assembly includes a slide rod slidably connected inside the fixed tube, the bottom end of the slide rod being rotatably connected to the top end of the gripper, and a limit rod being fixedly connected to the bottom end of the fixed tube, the limit rod being disposed inside the gripper.

[0011] Furthermore, the slide bar is internally threaded with a threaded rod, and a motor is installed at the top of the inside of the fixed tube, with the drive end of the motor fixedly connected to the top of the threaded rod.

[0012] Furthermore, the lubrication assembly includes an oil reservoir fixedly connected to the outer wall of the fixed pipe, an oil storage box fixedly connected inside the oil reservoir, an air bladder provided on the bottom side inside the oil reservoir, and the bottom side of the oil storage box connected to the top side of the air bladder.

[0013] Furthermore, a push rod is slidably connected to the bottom side of the oil storage tank, a push plate is fixedly connected to the top of the push rod, the push plate is located on the bottom side of the airbag, a first impact rod is fixedly connected to the bottom side of the push rod, and a second impact rod is fixedly connected to the top side of the right-side gripper.

[0014] Furthermore, a second spring is sleeved on the outer wall of the push rod, one end of the second spring is connected to the bottom side of the oil reservoir, the other end of the second spring is connected to the top of the first impact rod, and an oil outlet pipe is fixedly connected to the bottom side of the airbag.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the first and second impact rods cause the gripper to push the push rod and push plate to squeeze the airbag during the expansion and contraction process. This causes the airbag to draw out the lubricating oil from the oil storage box, and the lubricating oil squeezed out of the airbag is dripped onto the gripper through the oil outlet pipe, thereby lubricating it. This allows the gripping structure to self-lubricate during operation, reducing the number of times the operator needs to maintain it and increasing its service life.

[0017] 2. In this utility model, by inserting the insertion rod into the mounting base and using the first spring to press the insertion rod against the mounting base, the entire gripping structure is installed on the transfer processing equipment, thereby making the gripping structure easy to disassemble and install, and convenient for workers to replace it.

[0025] 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.

[0026] Reference Figure 1 , Figure 2 and Figure 4This utility model provides an embodiment of a gripping structure for the transfer and processing of leaf springs, including a mounting base 1, an insert plate 5 inserted into the bottom side of the mounting base 1, a fixing tube 2 fixedly connected to the bottom side of the insert plate 5, and a gripper 4 for gripping the leaf spring connected inside the fixing tube 2. (Refer to...) Figure 3 Two grooves are provided on the bottom side of the insert plate 5. A telescopic rod 7 is fixedly connected inside the grooves. An insert rod 9 is fixedly connected to the end of the telescopic rod 7. The insert rod 9 is inserted into the inside of the mounting base 1. By inserting the insert rod 9 into the mounting base 1, the insert plate 5 is fixed on the mounting base 1, and the entire gripping structure is installed on the transfer processing equipment. A first spring 8 is sleeved on the outer wall of the telescopic rod 7. One end of the first spring 8 is connected to one side inside the groove, and the other end of the first spring 8 is connected to one end of the insert rod 9. A lever 10 is fixedly connected to the outer wall of the insert rod 9. The first spring 8 is used to press the insert rod 9 against the inside of the mounting base 1, and the lever 10 is used to disengage the insert rod 9 from the mounting base 1.

[0027] Reference Figure 4 and Figure 5The fixed tube 2 has a sliding rod 6 inside, the bottom end of which is rotatably connected to the top end of the gripper 4. A limiting rod 11 is fixedly connected to the bottom end of the fixed tube 2, and is located inside the gripper 4. The sliding rod 6 pushes the top end of the gripper 4 to move, and the limiting rod 11 inside the gripper 4 causes the middle end of the gripper 4 to rotate and slide around the limiting rod 11 when the top end of the gripper 4 moves, thus expanding or contracting the gripper 4. A threaded rod 12 is threaded inside the sliding rod 6. A motor 13 is installed at the top end of the fixed tube 2, and the drive end of the motor 13 is fixedly connected to the top end of the threaded rod 12. The motor 13 drives the threaded rod 12 to rotate, thus driving the sliding rod 6 to slide inside the fixed tube 2. An oil storage tank 3 is fixedly connected to the outer wall of the fixed tube 2. An oil storage box 17 is fixedly connected inside the oil storage tank 3. An airbag 18 is located on the bottom side of the inside of the oil storage tank 3. The bottom side of the oil storage box 17 is connected to the top side of the airbag 18. The airbag 18 is used to extract lubricating oil from the oil reservoir 17. A push rod 20 is slidably connected to the bottom side of the oil reservoir 3, and a push plate 19 is fixedly connected to the top of the push rod 20. The push plate 19 is located on the bottom side of the airbag 18. The push rod 20 pushes the push plate 19 upward to squeeze the airbag 18, causing it to spray out the internal lubricating oil. A first impact rod 15 is fixedly connected to the bottom side of the push rod 20, and a second impact rod 16 is fixedly connected to the top side of the right gripper 4. The second impact rod 16 is used to extract the lubricating oil from the oil reservoir 17. The first impact rod 15 is impacted, which in turn pushes the push rod 20 to slide upward. The outer wall of the push rod 20 is fitted with a second spring 21. One end of the second spring 21 is connected to the bottom side of the oil reservoir 3, and the other end of the second spring 21 is connected to the top of the first impact rod 15. The push rod 20 is reset by means of the second spring 21. The bottom side of the airbag 18 is fixedly connected to an oil outlet pipe 14. The oil outlet pipe 14 drips the lubricating oil squeezed out of the airbag 18 onto the gripper 4, thereby lubricating it.

[0028] Working principle: First, the mounting base 1 is fixed to the transfer processing equipment by welding or riveting. Then, the push plate 10 is pressed to retract the insertion rod 9 into the groove. Next, the insertion plate 5 is inserted into the mounting base 1. Then, the push plate 10 is released, allowing the insertion rod 9 to be inserted into the interior of the mounting base 1 under the action of the first spring 8, thus fixing the insertion plate 5 onto the mounting base 1. This allows the entire gripping structure to be installed on the transfer processing equipment. In use, the extended gripper 4 is placed on the top side of the leaf spring, with the left and right grippers 4 positioned on the left and right sides of the leaf spring. Then, the motor 13 is started to drive the threaded rod 12 to rotate, causing the sliding rod 6 to push the top of the gripper 4 to move. When the top of the gripper 4 is pushed by the sliding rod 6, the middle end of the gripper 4 will be at the limit rod 11. The clamping mechanism rotates and slides around the limiting rod 11 under the constraint, causing the two grippers 4 to move closer together until the leaf spring is clamped. The leaf spring can then be clamped to the area where it needs to be processed. When the leaf spring needs to be released, simply reverse the motor 13 to reverse the threaded rod 12, and repeat the above actions in reverse to release the grippers 4 and the leaf spring. During the contraction or release of the grippers 4, the second impact rod 16 will push the first impact rod 15 to slide upward, causing the push rod 20 to drive the push plate 19 to move upward, thereby squeezing the airbag 18. This causes the airbag 18 to draw out the lubricating oil from the oil reservoir 17 and drip the squeezed lubricating oil from the airbag 18 onto the grippers 4 through the oil outlet pipe 14, thus lubricating them.

[0029] 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.
