Description

Technical Field

[0001] The invention belongs to the technical field of clamping tools, and in particular relates to a clamping tool and a clamping method for nitrogen spring processing. Background Art

[0002] The main principle of the clamping tool for nitrogen spring processing is to clamp the spring through the structure and design of the fixture and provide sufficient support to prevent it from moving or deforming. The tool must be able to provide sufficient clamping force to ensure that the spring does not deviate or move during the processing. At the same time, the tool should have high precision and consistency, and can accurately position and fix the spring to meet the processing requirements. The tool should have adjustable functions to adapt to springs of different shapes and sizes. The tool should choose wear-resistant and corrosion-resistant materials to ensure long-term stability and life. The clamping tool for nitrogen spring processing is usually made of high-strength, wear-resistant and corrosion-resistant materials, such as engineering plastics, alloy steel, etc. Choosing the right material can ensure that the tool has sufficient strength and stability. In summary, the clamping tool for nitrogen spring processing is a key tooling used to ensure the stability and precision of the spring during the nitrogen spring processing. They can provide reliable clamping and support forces to meet processing requirements by designing a reasonable fixture structure and using appropriate materials.

[0003] During the processing of nitrogen springs, sufficient stability is required to fix them for subsequent processing and testing. The existing clamping tools for nitrogen spring processing require operators to manually pick up and place them individually for processing and testing. At the same time, general fixtures can only fix a single nitrogen spring, resulting in low overall processing efficiency and high investment costs for the clamping tools. In addition, the nitrogen spring cannot be steered during processing, and can only be processed on one side, resulting in a long total processing time, which greatly reduces work efficiency. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a clamping tool and a clamping method for nitrogen spring processing.

[0005] The technical solution adopted to solve the above technical problems is: to provide a clamping tool for nitrogen spring processing, comprising a main body, a pillar is fixedly connected to the bottom of the main body, a base is fixedly connected to the bottom of the pillar, and a driving mechanism is installed on the top of the base; A clamping mechanism is installed at the bottom of the main body, and a plurality of limiting grooves are opened on both sides of the top of the main body; A plurality of fixing seats are fixedly connected to the middle end of the top of the main body, two rectangular grooves are provided on the top of the main body, and two rectangular openings are provided at the front end of the main body; A conveying mechanism is installed inside the two rectangular grooves, and an adjusting mechanism is installed inside the two rectangular grooves.

[0006] Furthermore, the driving mechanism includes two support plates fixedly connected to the top of the base, a first motor is fixedly connected between the two support plates, first driving shafts are fixedly connected on both sides of the first motor, the other ends of the two first driving shafts are fixedly connected to threaded rods, the outer walls of the two threaded rods are rotatably connected to threaded sleeves, and the outer walls of the two threaded sleeves are fixedly connected to two first fixed shafts.

[0007] Through the above technical solution, when in use, before the nitrogen spring is placed on the tooling, the driving mechanism is used to perform segmented adjustment so that the nitrogen spring can be transported, clamped, turned, and other operations can be performed, thereby improving the working performance of the clamping tooling. Specifically, the first motor between the two support plates is started to drive the threaded rods on the two first drive shafts to rotate, so that the first motor between the two support plates is started to drive the threaded rods on the two first drive shafts to rotate, and the two threaded sleeves can move on the threaded rods, thereby enabling relevant operations on the nitrogen spring to be performed, thereby greatly improving the working performance of the clamping tooling.

[0008] Furthermore, the clamping mechanism includes arc rods that are rotatably connected to the other ends of the two first fixed shafts, a support rod is rotatably connected between the two arc rods, a first connecting rod is fixedly connected to one side of the two arc rods, a second connecting rod is rotatably connected between the two first connecting rods, the other end of the second connecting rod is rotatably connected to a rectangular frame, and a fixed column is fixedly connected to the other side of the rectangular frame, a third connecting rod is rotatably connected between the tops of the two arc rods, and the other end of the third connecting rod is rotatably connected to a clamp seat, the outer walls of the bottoms of the two arc rods are fixedly connected to a connecting column, the other ends of the support rods are fixedly connected to the main body, the other ends of the fixed columns are fixedly connected to another rectangular frame, the outer wall of the clamp seat is slidably connected to the limiting groove, and the outer wall of the connecting column is fixedly connected to another plurality of arc rods.

[0009] Through the above technical scheme, when in use, the clamping mechanism can be adjusted by the driving mechanism so that the nitrogen spring can be clamped, which is convenient for the processing of the nitrogen spring, and a single clamp is used to clamp two nitrogen springs at the same time, thereby greatly improving the utilization efficiency of the clamping tooling. Specifically, as the threaded rod rotates, the threaded sleeve will drive the multiple arc rods to move to both sides with a certain arc, and through the connection of the first connecting rod and the second connecting rod, the multiple rectangular frames will move downward on the main body. At the same time, under the support of the support rod, the multiple arc rods will move with a certain arc, and then under the connection of the third connecting rod, the multiple clamping seats are pushed to slide in the corresponding limit grooves until they cooperate with the corresponding fixed seats to clamp the nitrogen spring, thereby achieving the clamping of the nitrogen spring, thereby greatly improving the working efficiency of the clamping tooling and improving the overall working efficiency.

[0010] Furthermore, the conveying mechanism includes an iron plate fixedly connected to one side of the main body, a second motor is fixedly connected to one side of the iron plate, a second driving shaft is fixedly connected to the output end of the second motor, two conveyor belts are rotatably connected to the outer wall of the second driving shaft, a plurality of conveyor shafts are rotatably connected to the inner walls of the two conveyor belts, two first helical gears are fixedly connected to the outer wall of the second driving shaft, the two conveyor belts are located inside the corresponding rectangular openings, the plurality of conveyor shafts are respectively located inside the corresponding rectangular grooves, and both ends of the plurality of conveyor shafts are rotatably connected to the main body.

[0011] Through the above technical scheme, when in use, the nitrogen spring can be transmitted through the transmission mechanism during processing, which reduces manual participation and thus speeds up work efficiency. Specifically, the second motor on one side of the iron plate is started to drive the two conveyor belts on the outer walls of the two second drive shafts to start rotating, and the first helical gear rotates therewith, and then multiple transmission shafts start to transmit, thereby driving multiple nitrogen springs to be transmitted to the tooling at a certain interval, thereby realizing the transmission of the nitrogen springs and greatly improving the processing efficiency of the nitrogen springs.

[0012] Furthermore, the adjustment mechanism includes two rotating shafts rotatably connected to corresponding rectangular frames, wherein a second helical gear is fixedly connected to the front end of one of the rotating shafts, a plurality of rubber rings are rotatably connected to the outer walls of the two rotating shafts, a plurality of second fixed shafts are rotatably connected inside the plurality of rectangular frames, a plurality of transmission wheels are rotatably connected to the outer walls of the plurality of second fixed shafts, a spur gear is fixedly connected to the outer walls of the two rotating shafts, the two first helical gears are respectively meshed with the corresponding second helical gears, and the outer walls of the plurality of rubber rings are respectively rotatably connected to the corresponding transmission wheels.

[0013] By means of the above technical scheme, when in use, after one side of the nitrogen spring is fixed and processed, it can be adjusted by the adjusting mechanism so that the nitrogen spring can be fully processed and operated, thereby improving the working performance of the clamping tooling. Specifically, as the threaded sleeve moves toward the middle end of the threaded rod, after the multiple transmission wheels on the multiple rectangular frames are higher than the height of the multiple transmission shafts, the second motor is started to drive the first helical gear to rotate, so that the second helical gear rotates along with it, and the rotating shaft rotates accordingly. At the same time, under the outer walls of the multiple rubber rings respectively connected with the corresponding transmission wheels, the two transmission wheels in one of the rectangular frames are driven to rotate in one direction, and under the rotation of the two spur gears, the other two transmission wheels are driven to rotate in the other direction, and under the obstruction of the fixed seat, the nitrogen spring can be slowly rotated about the center of the nitrogen spring itself under the rotation of the two, so as to realize the steering of the nitrogen spring. When the nitrogen spring is adjusted, it is clamped again for processing, and the operation is repeated until the processing is completed.

[0014] A clamping method for a clamping tool for nitrogen spring processing includes the following specific steps: Step 1: The nitrogen spring needs to be fixed with a clamping fixture during the processing. First, start the first motor between the two support plates to drive the threaded rods on the two first drive shafts to rotate. Since the two threaded sleeves are rotatably connected with the corresponding arc rods and connected with the connecting column, as the threaded rods rotate, the threaded sleeves will drive multiple arc rods to move to both sides with a certain arc. Through the connection of the first connecting rod and the second connecting rod, multiple rectangular frames will move downward on the main body. When the threaded sleeves are driven to move to a certain position on the threaded rods, the first motor stops moving, and at the same time, the second motor on one side of the iron plate is started to drive the two conveyor belts on the outer walls of the two second drive shafts to start rotating, and then multiple conveyor shafts start to transmit, thereby driving multiple nitrogen springs to be transmitted to the fixture at a certain interval to ensure that the position of the springs is correct and the clamp can firmly fix the springs; Step 2: When the nitrogen spring reaches a certain position, the second motor stops working, and then the first motor is started to continue to drive the rotation of the threaded rod. Under the support of the support rod, the multiple arc rods will move at a certain arc, and then under the connection of the third connecting rod, the multiple clamping seats are pushed to slide in the corresponding limit grooves until they cooperate with the corresponding fixed seats to clamp the nitrogen spring. Then the first motor stops working temporarily, and then ensure that the nitrogen spring remains stable and in the correct position during the clamping process, and the fixture firmly clamps the nitrogen spring to ensure that it will not move or shift during the processing, and then it is cut, polished and welded; Step 3: After one side of the nitrogen spring is processed, the first motor is started to move, driving the threaded sleeve to move toward the middle end of the threaded rod, and then the multiple clamps loosen the multiple nitrogen springs. Then, under the connection of the first connecting rod and the second connecting rod, the multiple rectangular frames will move upward until the multiple transmission wheels on the multiple rectangular frames are higher than the height of the multiple transmission shafts, so that they can fully support the nitrogen springs. At the same time, the second helical gear rises and meshes with the first helical gear. At this time, the first motor is stopped, and the second motor is started to drive the first helical gear to rotate, so that the second helical gear rotates accordingly, so that one of the rotating shafts rotates. Rotate, and at the same time, the outer walls of multiple rubber rings are respectively connected with the corresponding transmission wheels, driving the two transmission wheels in one of the rectangular frames to rotate in one direction. At the same time, under the meshing of the two spur gears, the other rotating shaft drives the other transmission wheel to rotate in the other direction, and under the blocking of the fixed seat, the nitrogen spring can slowly rotate around the center of the nitrogen spring itself under the rotation of the two, so as to realize the steering of the nitrogen spring, and then repeat the above steps to process it. After the processing is completed, release the clamping of the fixture in time, remove the processed nitrogen spring, and at the same time, ensure the cleaning and tidying of the fixture and the processing area to prepare for the next operation.

[0015] The beneficial effects of the present invention are as follows: (1) By designing a driving mechanism, a clamping mechanism, a transmission mechanism and an adjustment mechanism, the present invention can change the traditional clamping tool that can only clamp and fix one nitrogen spring when the clamping tool clamps the nitrogen spring, thereby increasing the performance of the clamping tool, and can turn the nitrogen spring when processing it, making the processing of the nitrogen spring more convenient and more comprehensive during testing, thereby greatly improving the working performance of the clamping tool; (2) By designing a driving mechanism and a clamping mechanism, the present invention can use a single tool to converge to the middle when the nitrogen spring enters the device, and can clamp two nitrogen springs at the same time, thereby greatly improving the utilization rate of the clamping tool and reducing the investment cost; (3) By designing a transmission mechanism and an adjustment mechanism, the present invention can allow the nitrogen spring to enter the tool by mechanical transmission, reducing manual participation, thereby greatly improving the overall work efficiency, and at the same time, the nitrogen spring can be rotated in the tool, so that the nitrogen spring can be more comprehensive during processing and testing, thereby greatly improving the working effect of the clamping tool.

[0023] A clamping method for a clamping tool for nitrogen spring processing includes the following specific steps: Step 1: The nitrogen spring needs to be fixed with a clamping fixture during the processing. First, the first motor 402 between the two support plates 401 is started to drive the threaded rods 404 on the two first drive shafts 403 to rotate. Since the two threaded sleeves 405 are rotatably connected with the corresponding arc rods 501, and under the connection of the connecting column 509, as the threaded rod 404 rotates, the threaded sleeve 405 will drive multiple arc rods 501 to move to both sides with a certain arc.

When the threaded sleeve 405 is driven to move to a certain position on the threaded rod 404, the first motor 402 stops moving at this time, and the second motor 1002 on one side of the iron plate 1001 is started at the same time to drive the two conveyor belts 1004 on the outer walls of the two second drive shafts 1003 to start rotating, and then multiple conveyor shafts 1005 start to transmit, thereby driving multiple nitrogen springs to be transmitted to the fixture at a certain interval to ensure that the position of the spring is correct and the clamp can firmly fix the spring; Step 2: When the nitrogen spring reaches a certain position, the second motor 1002 stops working, and then the first motor 402 is started to continue to drive the threaded rod 404 to rotate. Under the support of the support rod 502, the multiple arc rods 501 will move at a certain arc, and then under the connection of the third connecting rod 507, the multiple clamping seats 508 are pushed to slide in the corresponding limit grooves 6 until they cooperate with the corresponding fixed seats 7 to clamp the nitrogen spring. Then the first motor 402 stops working temporarily, and then ensures that the nitrogen spring maintains a stable and correct position during the clamping process, and the clamp firmly clamps the nitrogen spring to ensure that it will not move or shift during the processing, and then cut, grind and weld it; Step 3: After one side of the nitrogen spring is processed, the first motor 402 is started to move, driving the threaded sleeve 405 to move toward the middle end of the threaded rod 404, and then the multiple clamping seats 508 loosen the multiple nitrogen springs. Then, under the connection of the first connecting rod 503 and the second connecting rod 504, the multiple rectangular frames 505 will move upward until the multiple transmission wheels 1105 on the multiple rectangular frames 505 are higher than the height of the multiple transmission shafts 1005, so that they can fully support the nitrogen springs. At the same time, the second helical gear 1102 rises and meshes with the first helical gear 1006. At this time, the first motor 402 is stopped, and the second motor 1002 is started to drive the first helical gear 1006 to rotate, so that the second helical gear 1102 rotates accordingly. One of the rotating shafts 1101 is rotated, and at the same time, the outer walls of the multiple rubber rings 1103 are respectively connected to the corresponding transmission wheels 1105, driving the two transmission wheels 1105 in one rectangular frame 505 to rotate in one direction. At the same time, under the meshing of the two spur gears 1106, the other rotating shaft 1101 drives the other transmission wheel 1105 to rotate in the other direction, and under the obstruction of the fixed seat 7, the nitrogen spring can slowly rotate around the center of the nitrogen spring itself under the rotation of the two, so as to realize the steering of the nitrogen spring, and then repeat the above steps to process it. After the processing is completed, the clamping of the fixture is released in time, and the processed nitrogen spring is removed. At the same time, ensure that the fixture and the processing area are cleaned and tidied to prepare for the next operation.

9. A clamping method for a clamping tool for nitrogen spring processing according to any one of claims 1 to 8, characterized in that: The specific steps include: Step 1: The nitrogen spring needs to be fixed with a clamping tool during the processing. First, the first motor (402) between the two support plates (401) is started to drive the threaded rods (404) on the two first drive shafts (403) to rotate. Since the two threaded sleeves (405) are rotatably connected with the corresponding arc-shaped rods (501), and under the connection of the connecting column (509), as the threaded rods (404) rotate, the threaded sleeves (405) will drive the multiple arc-shaped rods (501) to move to both sides at a certain arc, and through the first connecting rod (503) and the second connecting rod (504). ), the plurality of rectangular frames (505) will move downward on the main body (1), and when the threaded sleeve (405) is driven to move to a certain position on the threaded rod (404), the first motor (402) stops moving, and at the same time the second motor (1002) on one side of the iron plate (1001) is started to drive the two conveyor belts (1004) on the outer walls of the two second drive shafts (1003) to start rotating, and then the plurality of conveyor shafts (1005) start to drive, thereby driving the plurality of nitrogen springs to be transmitted to the tooling at a certain interval, ensuring that the position of the springs is correct and the clamp can firmly fix the springs; Step 2: When the nitrogen spring reaches a certain position, the second motor (1002) stops working, and then the first motor (402) is started to continue to drive the threaded rod (404) to rotate. Under the support of the support rod (502), the multiple arc rods (501) will move at a certain arc, and then under the connection of the third connecting rod (507), the multiple clamping seats (508) are pushed to slide in the corresponding limit grooves (6) until they cooperate with the corresponding fixed seats (7) to clamp the nitrogen spring. Then the first motor (402) stops working temporarily, and then ensures that the nitrogen spring remains stable and in the correct position during the clamping process, and the clamp firmly clamps the nitrogen spring to ensure that it does not move or shift during the processing, and then it is cut, polished and welded; Step 3: After processing one side of the nitrogen spring is completed, the first motor (402) is started to move, driving the threaded sleeve (405) to move toward the middle end of the threaded rod (404), and then the multiple clamping seats (508) loosen the multiple nitrogen springs. Then, under the connection of the first connecting rod (503) and the second connecting rod (504), the multiple rectangular frames (505) will move upward until the multiple transmission wheels (1105) on the multiple rectangular frames (505) are higher than the height of the multiple transmission shafts (1005) so that they can fully support the nitrogen springs. At the same time, the second helical gear (1102) rises and meshes with the first helical gear (1006). At this time, the first motor (402) is stopped, and the second motor (1002) is started to drive the first helical gear (1006) to rotate, so that the second helical gear (1102) 2) Follow the rotation, so that one of the rotating shafts (1101) rotates, and at the same time, the outer walls of the multiple rubber rings (1103) are respectively connected to the corresponding transmission wheels (1105), driving the two transmission wheels (1105) in one of the rectangular frames (505) to rotate in one direction. At the same time, under the meshing of the two spur gears (1106), the other rotating shaft (1101) drives the other transmission wheel (1105) to rotate in the other direction, and under the obstruction of the fixed seat (7), the nitrogen spring can slowly rotate around the center of the nitrogen spring itself under the rotation of the two, so as to realize the steering of the nitrogen spring, and then repeat the above steps to process it. After the processing is completed, the clamping of the clamp is released in time, and the processed nitrogen spring is removed. At the same time, ensure that the clamp and the processing area are cleaned and tidied to prepare for the next operation.
