Description

Technical Field

[0001] This application relates to the field of calender manufacturing technology, and in particular to a calender body welding device. Background Technology

[0002] In the manufacturing process of the calender body, the welding and forming of the main frame is one of the important steps. The welding quality is related to the structural strength, stability and service life of the calender body.

[0003] Currently, in the welding process of the calender body, the loading and unloading of body parts generally rely on manual labor. Specifically, in the manual loading process, workers need to use trailers or forklifts to transport the body parts to be welded from the storage area to the welding area, and then move the parts onto the welding table. The handling process consumes a lot of physical strength for workers and is inefficient. In addition, workers are prone to fatigue during the handling process, which leads to unstable loading speed and thus affects the rhythm of the entire welding process.

[0004] Similarly, in the unloading stage after welding, workers need to move the welded machine parts off the welding table, a process that is also physically demanding and inefficient.

[0005] To address the aforementioned issues, a welding device for the body of a calender is now designed. Utility Model Content

[0034] 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.

[0035] This application provides a calender body welding device, which can solve the problem in related technologies that the loading and unloading of machine body parts in the welding process of calender body generally rely on manual labor, requiring manual handling of parts and resulting in low work efficiency.

[0036] Please see Figures 1-3 A calender body welding device includes: a welding station 1, and a welding robot 2 disposed on one side of the welding station 1. The welding station 1 is used to place the parts to be welded, and the welding robot 2 is used to weld the parts. A feeding mechanism 3 includes a mounting frame 31 disposed on one side of the welding station 1. A lifting platform 32 is slidably disposed on the mounting frame 31. A conveyor 33 is disposed on the other side of the lifting platform 32. A lifting component 34 is also disposed on the mounting frame 31. The lifting component 34 is used to drive the lifting platform 32 to rise and fall. The conveyor 33 is used to place the parts and to transport the parts to the welding station 1. The feeding mechanism 3 also includes a pushing unit 35, which is used to push the welded parts onto the conveyor 33.

[0037] In the initial state, the conveyor 33 is located below the mounting frame 31.

[0038] Loading process: The operator transfers the calender body parts to be welded from the trolley or forklift to the conveyor 33. Then, the lifting component 34 starts working, driving the lifting platform 32 to move up and down on the mounting frame 31, so that the height of the conveyor 33 matches the height of the welding station 1. When the height of the conveyor 33 is level with that of the welding station 1, the conveyor 33 starts and transports the parts placed on it to the welding station 1. Then, the welding robot 2 performs welding operations on the body parts placed on the welding station 1 according to the preset program and path.

[0039] Material unloading process: After welding is completed, the pushing unit 35 starts working and pushes the welded parts from the welding station 1 to the conveyor 33. At this time, the lifting component 34 drives the lifting platform 32 to rise and fall again, adjusting the conveyor 33 to the bottom of the mounting frame 31 so that the welded parts can be transferred to the trolley or forklift and transported to the next process or storage area.

[0040] By using welding station 1, welding robot 2, lifting platform 32, conveyor 33, lifting component 34 and pushing unit 35 in combination, automatic loading and unloading of machine parts is realized, eliminating the need for frequent manual handling of parts, greatly shortening the loading and unloading time, reducing waiting time in the production process, and thus improving the efficiency of the entire welding production process.

[0041] The combined use of conveyor 33 and lifting component 34 enables the parts to be placed on welding station 1, ensuring the consistency and stability of the parts placement position. This helps welding robot 2 to perform precise welding according to the preset program and improves the consistency of welding.

[0042] The lifting component 34 allows for flexible adjustment of the height of the lifting platform 32 and the conveyor 33 according to the size and welding requirements of different components, thus adapting to the welding needs of machine body components of different specifications and improving the versatility and adaptability of the equipment.

[0043] A welding robot is an automated device used in industrial production to perform welding tasks. It typically consists of a robot body, a control system, a welding power source, a welding torch, and sensors. It possesses high flexibility and can adapt to workpieces of different shapes and materials. Through programming, welding robots can quickly switch between different welding tasks; this is existing technology and will not be elaborated upon further.

[0044] like Figure 4 and Figure 6 As shown, the mounting frame 31 in this embodiment includes: a plurality of fixing plates 311 connected to the welding station 1; two columns 312 disposed opposite to each other between one side of the plurality of fixing plates 311; and a crossbeam 313 disposed between the top ends of the two columns 312.

[0045] Multiple fixing plates 311 serve to stabilize the entire mounting bracket foundation.

[0046] The two columns 312 are the main supporting structures, bearing the weight of the lifting platform 32 and the conveyor 33, ensuring the stability of the mounting frame in the horizontal direction, and enabling the lifting platform 32 to move smoothly up and down along the columns.

[0047] The crossbeam 313 strengthens the connection between the two uprights 312, improving the structural strength and stability of the entire mounting frame.

[0048] like Figure 4 and Figure 5 As shown, in one embodiment, the conveyor 33 includes two side plates 331 arranged opposite to each other on the side of the lifting platform 32 away from the mounting frame 31. One side plate 331 is connected to the lifting platform 32, and the other side plate 331 is provided with a drive motor 332 and a reducer 333. A plurality of rollers 334 are rotatably arranged between the two side plates 331, and a belt is provided for transmission between the plurality of rollers 334. The output shaft of the drive motor 332 is connected to the input shaft of the reducer 333, and the output shaft of the reducer 333 is provided with a rotating shaft 335. The other end of the rotating shaft 335 is connected to one end of any roller 334.

[0049] When the drive motor 332 starts, its output shaft begins to rotate, transmitting power to the reducer 333. The reducer 333 reduces and increases the torque of the power, then transmits it to the connected roller 334 via the rotating shaft 335. The roller 334 begins to rotate under the action of the power. Since the belt is connected to multiple rollers 334, the rotation of the roller 334 drives the belt to move, which in turn drives the other rollers 334 to rotate. At this time, the machine parts placed on the belt are transported to the welding station 1 along with the movement of the belt, completing the loading process. After welding is completed, the pushing unit 35 pushes the welded parts onto the conveyor 33. The conveyor 33 runs in reverse, transporting the parts to the next process or storage area, completing the unloading process.

[0050] like Figure 6 and Figure 7As shown, in one embodiment, the lifting component 34 includes a housing 341 disposed between multiple fixed plates 311. The housing 341 is located between two columns 312, and its top end is connected to the crossbeam 313. The lifting component 34 also includes a second drive motor 342 and a second reducer 343 disposed on the crossbeam 313, and a lead screw 344 rotatably disposed inside the housing 341. A movable cylinder 345 is threadedly connected to the outer side of the lead screw 344. Two transmission rods 346 are disposed opposite each other on the movable cylinder 345. The output shaft of the second drive motor 342 is connected to the input shaft of the second reducer 343, and the output shaft of the second reducer 343 is connected to one end of the lead screw 344. A through hole is provided on the housing 341, and the other end of the transmission rod 346 passes through the through hole and is connected to the lifting platform 32. A threaded groove adapted to the external thread of the lead screw 344 is opened inside the movable cylinder 345.

[0051] When the lifting platform 32 needs to be raised, the second drive motor 342 starts, and its output shaft drives the input shaft of the second reducer 343 to rotate. After the reducer 342 reduces the power and increases the torque, it drives the lead screw 344 to rotate through its output shaft.

[0052] Because the moving cylinder 345 is threadedly connected to the lead screw 344 and cannot rotate due to the constraint of the housing 341, the rotation of the lead screw 344 causes the moving cylinder 345 to move upward in a straight line along the lead screw 344. The movement of the moving cylinder 345 is transmitted to the lifting platform 32 through the transmission rod 346, causing the lifting platform 32 to rise. Conversely, when the lifting platform 32 needs to descend, the drive motor 342 reverses, causing the lead screw 344 to rotate in the opposite direction. The moving cylinder 345 then moves downward in a straight line along the lead screw 344, thereby causing the lifting platform 32 to descend.

[0053] The threaded drive has a self-locking property. When the drive motor 342 stops rotating, the lead screw 344 and the moving cylinder 345 will remain relatively stationary, and the lifting platform 32 will also remain stably in its current position, without descending on its own due to external forces. This ensures the safety of the lifting platform 32 during the lifting process.

[0054] The threaded transmission between the lead screw 344 and the moving cylinder 345 is smooth, reducing vibration and impact during the lifting process, enabling the lifting platform 32 to lift smoothly. For the conveyor 33 and machine body components placed on the lifting platform 32, it avoids displacement or damage of components due to vibration.

[0055] like Figure 6 and Figure 7 As shown, it should be further explained that the slide rails 4 are also provided on the two columns 312, and two sets of sliders 5 are arranged opposite to each other on the lifting platform 32, and the sliders 5 slide in cooperation with the corresponding slide rails 4.

[0056] When the lifting component 34 drives the lifting platform 32 to move up and down, the slider 5 on the lifting platform slides up and down along the slide rail 4 on the column 312. During the lifting process, the slide rail 4 provides precise guidance for the slider 5, ensuring that the lifting platform 32 can only move in a straight line in the vertical direction, without swaying or deviating to the left or right. At the same time, the sliding cooperation between the slider 5 and the slide rail 4 allows the lifting platform 32 to move up and down smoothly, reducing resistance during the movement.

[0057] like Figure 2 As shown, in this embodiment, there are two push units 35, which are arranged opposite each other on the side of the soldering station 1 away from the mounting bracket 31.

[0058] There are two push units 35, which are arranged opposite each other to form a symmetrical push force, so as to push the machine parts placed on the soldering station 1 more smoothly and effectively.

[0059] like Figure 2 and Figure 3 As shown, in one embodiment, the pushing unit 35 includes a housing 351 disposed at the bottom of the soldering station 1, a drive motor 3 and a reducer 3 disposed at one end of the housing 351, a lead screw 352 rotatably disposed inside the housing 351, and a push rod 353 slidably disposed on the soldering station 1. The output shaft of the drive motor 3 is connected to the input shaft of the reducer, and the output shaft of the reducer 3 is connected to either end of the lead screw 352. A movable cylinder 354 is threadedly connected to the lead screw 352. Two transmission rods 355 are disposed opposite each other on the movable cylinder 354. A through hole is provided on the housing 351, and the transmission rods 355 pass through the through hole and are connected to the push rod 353. A threaded groove adapted to the external thread of the lead screw 352 is provided inside the movable cylinder 354.

[0060] When it is necessary to push the component on the welding station 1, the drive motor 3 starts, and its output shaft drives the input shaft of the reducer 3 to rotate. After the reducer 3 reduces the power and increases the torque, it drives the lead screw 2 352 to rotate through its output shaft.

[0061] Since the movable cylinder 354 is threadedly connected to the lead screw 352 and cannot rotate due to the restriction of the housing 351, the rotation of the lead screw will cause the movable cylinder 354 to move linearly along the lead screw 352. The movement of the movable cylinder 354 is transmitted to the push rod 353 through the transmission rod 355, causing the push rod to slide on the welding station 1, thereby pushing the component on the welding station to the designated position. When it is necessary to stop pushing, the drive motor 3 stops rotating, the lead screw 352 and the movable cylinder 354 remain relatively stationary, and the push rod also stops moving.

[0062] By controlling the rotation direction and rotation time of the drive motor three, the pushing direction and pushing distance of the push rod can be easily adjusted to meet the pushing needs of parts of different sizes and shapes.

[0063] The threaded drive and sliding fit make the pushing unit 35 run smoothly, improving the comfort and reliability of the equipment.
