Description

Technical Field

[0001] The utility model relates to the technical field of workpiece welding, in particular to a workpiece welding positioning and clamping device. Background Art

[0002] In the manufacturing field, when designing a complex structural part, different workpieces usually need to be welded to form a fixed integrated structure to ensure the overall stability. In the process of welding the workpieces, the positioning accuracy of the welding parts needs to be ensured. When the accuracy is not enough, the overall welding strength will be reduced. The current welding process is that the staff fixes one set of workpieces and then manually holds another set of workpieces for welding. This method will cause the workpieces to be not accurately positioned due to hand shaking, resulting in reduced product molding and increased scrap rate.

[0003] In view of this, a design or technical improvement is now proposed to solve the above problems.

[0004] The above contents are only used to assist in understanding the technical solution of the present utility model, and do not constitute an admission that the above contents are the closest prior art. Utility Model Content

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] like Figure 1-5 The workpiece welding positioning clamping device shown in the figure comprises two groups of support frames 1, a connecting frame plate 11 is arranged between the two groups of support frames 1, and two groups of placing table plates 2 are arranged above the connecting frame plate 11 and are respectively located between the two groups of support frames 1; a fixing frame 21 is arranged on the placing table plate 2, and a pressing plate 22 that can move up and down is arranged between the placing table plate 2 and the fixing frame 21. Since the conventional welding method for the workpiece requires the worker to hold a group of welding parts, it is easy for the hand to shake during manual alignment welding, which leads to misalignment deviation at the alignment of the workpiece, and the forming degree of the product after welding is not high. Therefore, by arranging two groups of placing table plates 2, the workpieces to be welded can be placed on the placing table plates 2 for alignment respectively, which eliminates the action of holding the workpiece by hand, so that the workpiece will not shake initially. Since the welding gun will exert a certain force on the docking part of the workpiece during the welding process, in order to prevent the workpiece from moving during welding by the welding gun, a pressing plate 22 is arranged so that the pressing plate 22 can cooperate with the placing table plate 2 to clamp the workpiece, thereby further improving the stability of the workpiece.

[0025] In one embodiment, limiting grooves 23 are provided on both sides of the fixing frame 21, and convex plates 24 slidably engaged with the limiting grooves 23 are provided on both sides of the pressing plate 22. The pressing plate 22 can change the relative distance with the placing table 2 by sliding inside the limiting grooves 23. When it is necessary to fix the workpiece, the pressing plate 22 can be lifted first to prevent the workpiece from being placed on the placing table 2, and then the pressing plate 22 can be lowered to achieve the purpose of clamping the workpiece.

[0026] In one embodiment, a fastening bolt 25 is also threadedly connected to the fixing frame 21, and the fastening bolt 25 movably engages with the surface of the pressing plate 22. Since the pressing plate 22 presses the workpiece by its own gravity, the workpiece may still be displaced during certain welding processes with greater force. Therefore, a fastening bolt 25 is further provided, and the upper surface of a pair of pressing plates 22 is engaged by rotating the fastening bolt 25, so that the pressing plate 22 can exert a stronger clamping and pressing effect on the workpiece to ensure better stability.

[0027] In one embodiment, a lifting rod 26 movably connected to the fixing frame 21 is further provided on the pressing plate 22. Since the pressing plate 22 is a plate-like structure and has a certain weight, it is difficult to lift it when it is necessary to open the pressing plate 22 to place a workpiece. Therefore, a lifting rod 26 is provided on the pressing plate 22 so that the staff can manually hold the lifting rod 26 to lift up the pressing plate 22, so as to facilitate the staff to place the workpiece on the placement table 2.

[0028] In one embodiment, the fixed frame 21 is rotatably connected to the support frame 1 through movable shafts 3 set on both sides, and outrigger frame plates 31 are set at both ends of the connecting frame plate 11. The outrigger frame plates 31 are threadedly connected with adjusting bolts 32 that movably engage with the lower surface of the placement table 2. Since some workpieces need to have a relative angle requirement when welding, movable shafts 3 are set on both sides of the fixed frame 21 so that the placement table 2 and the fixed frame 21 can rotate. Then, by rotating the adjusting bolts 32, it supports the lower surface of the placement table 2, thereby changing the inclination angle of the placement table 2, so as to drive the workpiece placed on the upper end thereof to adjust the angle, thereby ensuring that the device has higher applicability.

[0029] In one embodiment, a drop port 4 is further provided on the connecting frame plate 11 and is located between the two sets of placement plates 2. During the welding process of the workpiece, welding slag will fall, and thus a drop port 4 is provided on the connecting frame plate 11, so that the fallen welding slag can fall to the ground through the drop port 4 or be placed in a receiving trough at the lower end of the drop port 4 and then collected, which is convenient for subsequent cleaning work.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
