Description

Technical Field

[0001] This utility model belongs to the field of reinforcing plate processing technology, and relates to automotive door hinge reinforcing plates, particularly a processing table for automotive door hinge reinforcing plates. Background Technology

[0002] A car door hinge reinforcement plate is a reinforcing structural component installed at the hinge position of a car door. It is usually made of metal and its main function is to enhance the connection strength between the door and the car body, improve the durability and stability of the door. The reinforcement plate can effectively distribute the pressure on the door hinge and prevent material fatigue, deformation or breakage caused by frequent opening and closing of the door. In the car manufacturing process, the welding of the door hinge reinforcement plate is a key step, which directly affects the strength and durability of the door. During welding, it is usually done on a processing table, so a processing table for car door hinge reinforcement plates is required.

[0003] Traditional machining tables are usually designed with a fixed height, which may cause workers of different heights to adopt unsuitable postures when operating them. Shorter workers may need to bend over or stand on tiptoe to weld, while taller workers may need to bend their knees or bend over. Working in an uncomfortable posture for a long time on a machining table with a fixed height can lead to problems such as muscle fatigue and joint pain. Fatigue not only affects the worker's work efficiency and concentration, but may also lead to a decline in welding quality and an increase in the defect rate. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a processing table for automotive door hinge reinforcement plates. The technical problem this utility model aims to solve is: how to make the processing table usable by workers of different heights and to achieve automatic collection of reinforcement plates.

[0005] The objective of this utility model can be achieved through the following technical solutions: A processing table for automotive door hinge reinforcement plates includes an operating table. Support seats are provided at both ends of the bottom of the operating table, and a base plate is fixed to the bottom of each support seat. A lifting mechanism for raising and lowering the operating table is provided at the bottom of the operating table. Two clamping plates are symmetrically arranged on the top of the operating table. A first moving mechanism for moving the two clamping plates is provided on the top of the operating table. A placement platform is fixed on the top of the operating table and located below the two clamping plates. A connecting plate is provided at one end of the top of the placement platform, and a second moving mechanism for moving the connecting plate is provided at the bottom of the placement platform. A collection mechanism for collecting automotive door hinge reinforcement plates is provided at one end of the bottom of the operating table. During use, the height of the operating table can be adjusted via the lifting mechanism, allowing it to be adjusted according to the worker's height. This avoids workers needing to bend over or stand on tiptoe, reducing muscle fatigue and joint pain caused by improper working posture, improving worker comfort and work efficiency. The collection mechanism automatically collects and processes the welded reinforcement plates, reducing manual collection time and improving work efficiency.

[0006] Preferably, the lifting mechanism includes a second bidirectional lead screw, which is disposed at the bottom of the operating platform. Both ends of the second bidirectional lead screw are rotatably connected to the inner sidewalls of two support seats. A first motor is fixed to the outer sidewall of one of the support seats, and the output shaft of the first motor is fixed to the second bidirectional lead screw. Two second lead screw nuts are symmetrically sleeved on the sidewall of the second bidirectional lead screw, and both second lead screw nuts are adapted to the second bidirectional lead screw. A connecting rod is rotatably connected to the top of each of the two second lead screw nuts. Two columns are penetrating the top of each of the two support seats. The four columns are arranged in pairs, and the same connecting shaft is fixed to the sidewalls of the two pairs of columns. One end of each of the two connecting rods is connected to one of the two support seats. A rotating connecting shaft drives a first motor to rotate a second bidirectional lead screw. This, in conjunction with two second lead screw nuts, causes one end of each of the two connecting rods to move closer or further apart. As the ends of the two connecting rods move closer or further apart, the angle between the two connecting rods and the second bidirectional lead screw gradually decreases or increases. This, combined with the two connecting shafts, causes the four columns to rise or fall, thus completing the height adjustment of the operating table. This allows for use by workers of different heights, eliminating the need for workers to bend over or stand on tiptoe for welding. It avoids prolonged periods of uncomfortable work posture, which can lead to muscle fatigue, joint pain, and other problems. This prevents negative impacts on worker efficiency and concentration, improves welding quality, and reduces the defect rate.

[0007] Preferably, the first moving mechanism includes two support plates, which are symmetrically fixed to one end of the top of the operating table. The inner sidewalls of the two support plates are rotatably connected to the same first bidirectional lead screw. The sidewalls of the first bidirectional lead screw are symmetrically fitted with two first lead screw nuts, and both first lead screw nuts are adapted to the first bidirectional lead screw. The two first lead screw nuts are respectively fixed to one end of two clamping plates. A slide block is fixed to the other end of the top of the operating table. Two sliders are symmetrically slidably connected to the top of the slide block, and the two sliders are respectively fixed to the other end of the two clamping plates. A second motor is fixed to the outer sidewall of one of the support plates, and the output shaft of the second motor is fixed to the first bidirectional lead screw. The second motor drives the first bidirectional lead screw to rotate, which, together with the two first lead screw nuts and the two sliders, drives the two clamping plates to move closer to each other until the two clamping plates are tightly fitted to both ends of the car door hinge and the reinforcing plate, thus completing the fixing of the car door hinge and the reinforcing plate.

[0008] Preferably, the second moving mechanism includes two support plates, which are symmetrically fixed at both ends of the bottom of the placement platform. The inner sidewalls of the two support plates are rotatably connected to the same lead screw, and one end of the lead screw passes through the outer sidewall of one of the support plates. A through groove is provided in the middle of the top of the placement platform. A third lead screw nut is slidably connected to the sidewall of the through groove. One end of the third lead screw nut is sleeved on the sidewall of the lead screw, and the third lead screw nut and the lead screw are adapted to each other. The other end of the third lead screw nut is fixed to the connecting plate. A gear is sleeved on one end of the lead screw. A rack is fixed to the outer sidewall of one of the first lead screw nuts, and the rack and gear mesh. The second motor drives the first bidirectional lead screw to rotate in the opposite direction. At this time, the two first lead screw nuts and the two clamping plates move away from each other at the same time. When the two clamping plates move away from each other, the fixation of the reinforcing plate is released. When the two first lead screw nuts move away from each other, one of the first lead screw nuts drives the rack to move. The movement of the rack, in conjunction with the gear, drives the lead screw to rotate. Under the restriction of the through groove, the connecting plate is moved by the third lead screw nut.

[0009] Preferably, the collection mechanism includes a through hole. A through hole is provided at the other end of the top of the operating table near the placement table. A guide plate is fixedly inclined to the inner wall of the through hole. When the connecting plate moves, the welded reinforcing plate can be moved towards the end near the through hole until the reinforcing plate is pushed out from the top of the placement table, falls through the through hole onto the top of the guide plate, and slides from the guide plate into the collection container for collection. This eliminates the need for manual collection and processing, saves time, and improves work efficiency.

[0010] Compared with the prior art, the processing table for the automotive door hinge reinforcement plate of this utility model has the following advantages: 1. In this utility model, the height of the operating table can be adjusted by the lifting mechanism. This allows the height of the operating table to be adjusted according to the height of the worker, avoiding the need for the worker to bend over or stand on tiptoe while working, reducing muscle fatigue and joint pain caused by improper working posture, and improving the worker's comfort and work efficiency.

[0011] 2. In this utility model, the connecting plate is moved by the second moving mechanism, and the collecting mechanism can automatically collect and process the welded reinforcing plate, reducing the time for manual collection and improving work efficiency.

[0012] 3. In this utility model, the welded reinforcing plate is processed by an automated mechanism, which avoids workers directly contacting the high-temperature reinforcing plate, reduces the risk of burns, and improves the safety performance of the equipment. Attached Figure Description

[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

A collection mechanism for collecting the car door hinge reinforcement plate is provided at one end of the bottom of the operating table 1.

[0017] Furthermore, the lifting mechanism includes a second bidirectional lead screw 15, which is disposed at the bottom of the operating platform 1. The two ends of the second bidirectional lead screw 15 are rotatably connected to the inner sidewalls of two support seats 2 respectively. A first motor 4 is fixed to the outer sidewall of one of the support seats 2, and the output shaft of the first motor 4 is fixed to the second bidirectional lead screw 15. Two second lead screw nuts 16 are symmetrically sleeved on the sidewall of the second bidirectional lead screw 15, and both second lead screw nuts 16 are adapted to the second bidirectional lead screw 15. A connecting rod 14 is rotatably connected to the top of each of the two second lead screw nuts 16.

[0018] Furthermore, each of the two support bases 2 has two columns 12 running through its top. The four columns 12 are arranged in pairs, and the same connecting shaft 13 is fixed to the side wall of the two sets of columns 12. One end of each of the two connecting rods 14 is rotatably connected to the two connecting shafts 13.

[0019] Furthermore, the first moving mechanism includes two support plates 8, which are symmetrically fixed to one end of the top of the operating table 1. The inner sidewalls of the two support plates 8 are rotatably connected to the same first bidirectional lead screw 9. The sidewalls of the first bidirectional lead screw 9 are symmetrically fitted with two first lead screw nuts 10, and both first lead screw nuts 10 are adapted to the first bidirectional lead screw 9. The two first lead screw nuts 10 are respectively fixed to one end of the two clamping plates 7. The other end of the top of the operating table 1 is fixed with a slide block 5. The top of the slide block 5 is symmetrically slidably connected with two sliders 6, and the two sliders 6 are respectively fixed to the other end of the two clamping plates 7. The outer sidewall of one of the support plates 8 is fixed with a second motor 11, and the output shaft of the second motor 11 is fixed to the first bidirectional lead screw 9.

[0020] Furthermore, the second moving mechanism includes two support plates 22, which are symmetrically fixed at both ends of the bottom of the placement platform 17. The inner sidewalls of the two support plates 22 are rotatably connected to the same lead screw 23, and one end of the lead screw 23 passes through the outer sidewall of one of the support plates 22. A through groove 21 is provided in the middle of the top of the placement platform 17. A third lead screw nut 24 is slidably connected to the sidewall of the through groove 21. One end of the third lead screw nut 24 is sleeved on the sidewall of the lead screw 23, and the third lead screw nut 24 and the lead screw 23 are adapted to each other. The other end of the third lead screw nut 24 is fixed to the connecting plate 25. A gear 26 is sleeved on one end of the lead screw 23. A rack 20 is fixed to the outer sidewall of one of the first lead screw nuts 10, and the rack 20 and the gear 26 mesh.

[0021] Furthermore, the collection mechanism includes a through hole 18. A through hole 18 is provided at the other end of the top of the operating table 1 near the placement table 17. A guide plate 19 is fixed obliquely to the inner wall of the through hole 18.

[0022] The working principle of this utility model is as follows: During use, the height of the operating platform 1 is first adjusted according to the worker's height. During adjustment, the power switch of the first motor 4 is turned on, driving the first motor 4 to rotate the second bidirectional lead screw 15. This, in conjunction with the two second lead screw nuts 16, causes one end of the two connecting rods 14 to move closer or further apart. As the ends of the two connecting rods 14 move closer or further apart, the included angle between the two connecting rods 14 and the second bidirectional lead screw 15 gradually decreases or increases. This, in conjunction with the two connecting shafts 13, causes the four columns 12 to rise or fall, thus completing the height adjustment of the operating platform 1. This modular design allows for use by workers of different heights, eliminating the need for bending over or tiptoeing during welding. This avoids prolonged periods of uncomfortable posture, which can lead to muscle fatigue and joint pain, thus improving worker efficiency and concentration, enhancing welding quality, and reducing defect rates. The car door hinge and reinforcing plate are placed on top of the placement platform 17, and the power switch of the second motor 11 is turned on. The second motor 11 drives the first bidirectional lead screw 9 to rotate, which, in conjunction with the two first lead screw nuts 10 and two sliders 6, moves the two clamping plates 7 closer together until the two clamping plates 7... Both ends of the connecting plate 25 and the reinforcing plate are tightly fitted together, thus completing the fixing of the car door hinge and the reinforcing plate. At this time, the connecting plate 25 is located at one end of the top of the placement platform 17. At this time, the worker can use a welding torch to weld the car door hinge and the reinforcing plate. After welding, the second motor 11 drives the first bidirectional lead screw 9 to rotate in the opposite direction. At this time, the two first lead screw nuts 10 and the two clamping plates 7 move away from each other simultaneously. When the two clamping plates 7 move away from each other, the fixing of the reinforcing plate is released. When the two first lead screw nuts 10 move away from each other, one of the first lead screw nuts 10 drives the rack. The rack 20 moves, and the gear 26 drives the lead screw 23 to rotate. Under the restriction of the through slot 21, the connecting plate 25 is moved by the third lead screw nut 24. The welded reinforcing plate can be moved to the end closer to the through hole 18 until the reinforcing plate is pushed out from the top of the placement table 17, falls through the through hole 18 onto the top of the guide plate 19, and slides from the guide plate 19 into the collection container for collection. No manual collection and processing is required, saving time and improving work efficiency. Since the surface temperature of the newly welded reinforcing plate is high, this can avoid burning workers and improve the safety performance of the device.

[0023] In summary, in this utility model, the height of the operating table 1 can be adjusted according to the worker's height, avoiding the need for the worker to bend over or stand on tiptoe while working, reducing muscle fatigue and joint pain caused by improper working posture, and improving the worker's comfort and work efficiency.
