Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and in particular relates to a full-automatic assembly line type lifting machine slide welding production line. Background Art

[0002] In existing industries, this process is mostly implemented in a fully manual mode or a manual + separate workstation mode to achieve production. The positioning of products in the welding process and other aspects still rely on auxiliary tooling positioning and manual spot welding to form the welding process.

[0003] Generally, the following two methods are used: 1. Manual mode: After the components are shaped by manual tooling or jig structures, they are fixed by spot welding in sequence, and then the welding operation is performed manually throughout the process according to the process and manufacturing requirements until the components are welded. 2. Manual + single workstation mode: Similar to the manual mode, the components are shaped by manual tooling or jig structures in the early stage, and then fixed by spot welding in sequence. The purpose is to effectively connect the components through spot welding, and then transport them to the fixed welding workstation by heavy-duty overhead cranes or transport trusses for large-volume welding work.

[0004] The lift slide has an irregular shape and is heavy, so manual assistance is usually required during welding to achieve effective welding. The main reason for this phenomenon is that the material form changes of the slide and other components, as well as shrinkage and deformation during welding, lead to the inability of traditional methods to effectively solve the problems of component material supply, component assembly welding, full process welding, finished product off-line, and compatible co-production of similar and different-level products.

[0005] In the Chinese patent application publication number CN109822175A, an automatic welding production line is disclosed, including a frame assembly, a feeding conveyor device arranged on the frame assembly, an input device arranged at the output end of the feeding conveyor device, a main conveyor belt arranged on one side of the input device, and a tinning device arranged on the main conveyor belt in sequence. However, in the actual production process, although this equipment can play the role of automatic operation, its transmission conveyor line can only be used for the transmission of small or light-weight workpieces. For large, irregular and heavy workpieces, it cannot achieve effective clamping, which will affect the actual welding point. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a fully automatic assembly line type lift slide welding production line, which solves the above-mentioned technical problems existing in the prior art.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] like Figure 1 As shown, an embodiment of the utility model provides a fully automatic assembly line type lift slide welding production line, including a transmission line 1, a rotating station 2, and a welding station 3.

[0036] like Figure 2 , Figure 3 , Figure 5 As shown, the transmission line 1 is used for transmitting the workpiece to be processed; it includes a working platform 11, a transmission component 12, and a lifting component 13. The working platform 11 is a strip structure, and the transmission component 12 is located on both sides of the working platform 11 for carrying and transmitting the workpiece to be processed; at this time, the transmission component 12 includes a driving gear member 121 and a transmission chain 122 located at the end, and the transmission chain 122 is driven by the driving gear member 121. At the same time, the upper part of the transmission chain 122 is used to carry the workpiece to be processed. This transmission method can greatly meet the weight transmission requirements of the workpiece to be processed, and can achieve a weight transmission of several hundred kilograms, which meets the transmission operation of heavy-weight workpieces.

[0037] The lifting assembly 13 is located in the middle of the working platform 11, including a lifting electric cylinder 131 and a clamping member 132 located in the left and right directions. A slide member 133 is arranged between the two sets of clamping members 132. The lifting electric cylinder 131 realizes lifting and lowering movements in the up and down directions. At the beginning, the lifting assembly 13 is placed as a whole below the working platform 11. When the transmission assembly 12 transfers the workpiece to be processed to the top of the lifting assembly 13, the lifting assembly 13 performs a lifting movement again, and the workpiece to be processed is separated from the transmission assembly 12 as a whole and lifted, which simultaneously plays a role of limiting the position during the transmission process. The setting of the clamping member 132 can effectively accommodate the problems of misalignment of the placement position and size deviation of the workpiece to be processed, ensuring the accuracy of welding.

[0038] The upper part of the slide 133 is used to support the workpiece to be processed, and two sets of clamping members 132 are used to clamp the two sides of the workpiece to be processed on the slide 133, reducing the sliding of the workpiece to be processed to the two sides. At the same time, the slide 133 realizes sliding displacement in the front and rear directions, that is, when the workpiece to be processed is located on the bearing surface of the slide 133. Buffers 1331 are provided on both sides of the slide 133, and the upper height of the buffer 1331 is higher than the upper surface of the slide 133. Therefore, the bottom of the workpiece to be processed does not directly contact the upper surface of the slide 133, reducing the friction between the slide 133 and the workpiece to be processed.

[0039] A first reference correction mechanism 14 and a second reference correction mechanism 15 are respectively arranged on both sides of the working platform 11, and the first reference correction mechanism 14 and the second reference correction mechanism 15 are respectively used to correct the position of the workpiece extending out of the two sides of the working platform 11 (during the transmission process of the transmission component 12, there will still be deviations in the transmission position, and a separate correction station is set for this purpose). After the correction position is completed, it is convenient for the rotating station 2 to clamp it as a whole.

[0040] like Figure 4 As shown, the first reference correction mechanism 14 and the second reference correction mechanism 15 use the same structural parts; the first reference correction mechanism 14 includes a first fixed seat 141, and a first conveyor belt 142 arranged in the front-to-back direction. The movement of the first conveyor belt 142 synchronously drives the movement of the first calibration plate 143 located above, so that the first calibration plate 143 can perform position calibration on the end of the workpiece to be processed, which makes the operation more convenient and does not affect the transmission operation of the transmission component 12 on the workpiece to be processed.

[0041] like Figure 6 , Figure 7 As shown, the rotating station 2 is located at the side of the transmission line 1, and includes an extended clamping arm 21 and a rotating motor 22 located at the end. The workpiece is clamped by the clamping arm 21, and the rotating direction of the clamping arm 21 is controlled by the rotating motor 22.

[0042] A clamping assembly 23 is disposed at the front end portion of the clamping arm 21 . The clamping assembly 23 includes a clamping block 231 at the top and a supporting bottom wheel 232 at the bottom.

[0043] The supporting bottom wheel 232 extends toward the middle to support the bottom of the workpiece to be processed. The clamping block 231 is located on the upper part of the workpiece to be processed and clamps the workpiece from the top and bottom directions. The clamping operation of the clamping assembly 23 realizes the clamping of the workpiece by the clamping arm 21.

[0044] The welding station 3 is located above the transmission line 1, and the clamping arm 21 clamps the workpiece to be processed, and the rotating motor 22 located at the end realizes multi-angle rotation, so that the welding station 3 can perform multi-angle welding operations on the workpiece to be processed clamped by the rotating station 2. That is, every time the rotating station 2 rotates an angle, the welding station 3 can weld the position displayed by the station.

[0045] There are multiple groups of transmission lines 1, and the transmission of the workpieces to be processed is achieved through the adjacent docking components 111, so that each group of transmission lines 1 and the rotating station 2 form a processing station, that is, the entire process from loading, clamping, rotation to welding forms a whole. A docking component 111 is provided at the front end of the transmission direction where the working platform 11 is located (located between the two groups of working platforms 11, which is convenient for the transmission of the workpieces to be processed). The workpieces to be processed located at the previous station are connected to the working platform 11 where the station is located through the docking component 111. According to different set programs, the process position of each set of welding is not the same, and the number of transmission lines 1 can be increased according to the actual needs of the production line.

[0046] The entire set of equipment does not require any personnel involvement during the actual production process. Only personnel who are not direct front-line participants in equipment maintenance and servicing are required, which greatly reduces the occurrence of such hazards.

[0047] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
