Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a spot welding fixture for sheet metal parts processing. Background Technology

[0002] Sheet metal part spot welding fixtures are fixtures used to clamp and position sheet metal parts during electric welding. They can firmly position the sheet metal parts, prevent displacement, and facilitate precise spot welding. They are applicable to various sheet metal part processing scenarios.

[0003] However, when using spot welding fixtures, existing sheet metal spot welding fixtures usually adopt a fixed structure, which cannot be flexibly adjusted according to the size or shape of the workpiece. The installation position and angle of most fixtures are locked in a single direction, lacking a multi-degree-of-freedom adjustment mechanism. This means that when dealing with sheet metal parts of different sizes or irregular shapes, operators need to frequently change fixtures or manually adjust the position of the workpiece. This rigid structure cannot adapt to the production rhythm of multiple varieties and small batches, limiting its versatility and scope of application. At the same time, the adjustment function of existing fixtures relies on additional tools, which not only increases the complexity of operation but also prolongs the preparation time, seriously affecting the overall production efficiency. Furthermore, existing designs often cannot ensure the stable positioning of sheet metal parts during the spot welding process. Common clamping structures have the risk of loosening, leading to workpiece displacement or deformation. Especially in high-precision welding scenarios, the height adjustment of existing clamping columns is limited, making it impossible to achieve fine control. When the clamping force is unevenly distributed, it is easy to cause the welding point to shift or become incomplete, reducing the yield rate. Utility Model Content

[0004] The main purpose of this utility model is to provide a spot welding fixture for sheet metal parts processing, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A sheet metal part processing spot welding fixture includes a fixture working plate and sliding slots. The sliding slots are formed on both sides of the fixture working plate. Two mounting horizontal plates are provided on the upper end of the fixture working plate. Sliding blocks are integrally formed on both sides of the mounting horizontal plates. A rotating mounting plate is movably mounted on the upper end of the sliding blocks. A frame plate is fixedly mounted on the upper end of the rotating mounting plate. A lifting mounting plate is integrally formed on the upper end of the frame plate. A clamping structure is movably mounted on the outer side of the lifting mounting plate.

[0007] As a further embodiment of this utility model, the sliding block is movably connected into the sliding slot, and the mounting plate slides back and forth around the fixture working plate and the sliding slot via the sliding block.

[0008] As a further embodiment of this utility model, a rotating handle is fixedly installed at the upper end of the rotating mounting plate at the center of the frame plate, and the end of the rotating handle passes through the rotating mounting plate and is movably connected to the upper end of the mounting cross plate.

[0009] As a further embodiment of this utility model, the front of the frame plate is L-shaped, and the frame plates on both sides are symmetrically arranged and installed.

[0010] As a further embodiment of this utility model, the clamping structure includes a lifting clamping block, an adjusting knob, clamping columns, a side locking knob, and a lifting locking knob. The lifting clamping block is movably installed on the outside of the frame plate. The adjusting knob is threadedly installed on the upper end of the lifting clamping block. The two clamping columns movably penetrate through the inner sides of the lifting clamping block. The side locking knob is threadedly installed on both sides of the lifting clamping block. The lifting locking knob is threadedly installed on the side of the lifting clamping block adjacent to the frame plate.

[0011] As a further embodiment of this utility model, the top of the adjustment knob is movably connected to the top of the frame plate, the lifting and locking knob is movably connected to the center of the frame plate, and the end of the side locking knob penetrates into the lifting and pressing block and presses against the outside of the pressing column, with the pressing column located above the clamping work plate.

[0012] Compared with the prior art, the present invention has the following advantages: through the cooperation of the sliding block and the sliding groove, the mounting plate and the entire clamping mechanism can move back and forth along the working plate of the fixture. Combined with the rotation function driven by the rotating handle, the horizontal position and angle of the clamping structure can be easily adjusted. The multi-degree-of-freedom adjustment method greatly improves the fixture's adaptability to sheet metal parts of different sizes and shapes, and has strong versatility.

[0013] The clamping structure is ingeniously designed. The height of the lifting clamping block can be precisely controlled by adjusting the knob, thereby driving the clamping column to accurately press down onto the workpiece surface. The independent side locking knob and lifting locking knob are used to lock the extension position of the clamping column and the height of the entire clamping block, respectively, ensuring that the sheet metal parts are firmly clamped during spot welding, effectively preventing displacement, and ensuring the accuracy and quality of welding processing.

[0014] Each adjustment mechanism is designed to be operated manually with knobs or handles, and locking is quick. Operators can quickly clamp and position the workpiece without using complicated tools, which significantly reduces preparation time and improves production efficiency. It is especially suitable for multi-variety, small-batch production rhythms. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-3 As shown, a spot welding fixture for sheet metal parts processing is described. Please refer to it carefully. Figures 1-3 It includes a fixture working plate 1 and a sliding slot 2. The sliding slot 2 is opened on both sides of the fixture working plate 1. Two mounting horizontal plates 3 are provided on the upper end of the fixture working plate 1. Sliding blocks 4 are integrally formed on both sides of the mounting horizontal plates 3. A rotating mounting plate 5 is movably installed on the upper end of the sliding blocks 4. A frame plate 7 is fixedly installed on the upper end of the rotating mounting plate 5. A lifting mounting plate 8 is integrally formed on the upper end of the frame plate 7. A clamping structure 9 is movably installed on the outer side of the lifting mounting plate 8.

[0021] Please refer to this carefully. Figure 1 and Figure 2 The sliding block 4 is inserted into the sliding slot 2 for movable connection, and the mounting plate 3 slides back and forth around the fixture working plate 1 and the sliding slot 2 via the sliding block 4.

[0022] Specifically, the sheet metal parts to be welded are placed on top of the fixture work plate 1. By using the sliding block 4 to slide around the sliding slot 2, the mounting plate 3 can move back and forth above the fixture work plate 1, changing the front and back positions of the upper parts.

[0023] Please refer to this carefully. Figures 1-3 The upper end of the rotating mounting plate 5 is fixedly installed at the center of the frame plate 7 with a rotating handle 6. The end of the rotating handle 6 passes through the rotating mounting plate 5 and is movably connected to the upper end of the mounting plate 3.

[0024] Specifically, the rotating handle 6 is used to drive the rotating mounting plate 5 to rotate above the mounting plate 3, thereby changing the overall orientation of the upper components.

[0025] Please refer to this carefully. Figures 1-3The front of the frame panel 7 is L-shaped, and the frame panels 7 on both sides are symmetrically arranged and installed.

[0026] Please refer to this carefully. Figure 3 The clamping structure 9 includes a lifting clamping block 10, an adjusting knob 11, a clamping column 12, a side locking knob 13, and a lifting locking knob 14. The lifting clamping block 10 is movably installed on the outside of the frame plate 7. The adjusting knob 11 is threadedly installed on the upper end of the lifting clamping block 10. The two clamping columns 12 movably pass through the inside of the lifting clamping block 10 on both sides. The side locking knob 13 is threadedly installed on both sides of the lifting clamping block 10. The lifting locking knob 14 is threadedly installed on the side of the lifting clamping block 10 adjacent to the frame plate 7.

[0027] Please refer to this carefully. Figure 3 The top of the adjustment knob 11 is movably connected to the top of the frame plate 7, the lifting locking knob 14 is movably connected to the center of the frame plate 7, and the end of the side locking knob 13 passes through the lifting pressure block 10 and presses against the outside of the pressure column 12. The pressure column 12 is located above the clamping work plate 1.

[0028] Specifically, by adjusting the rotation of knob 11 at the top of frame plate 7, and then driving the lifting clamping block 10 to descend around frame plate 7 via threaded connection, the clamping column 12 descends and presses against the plate. Then, the lifting locking knob 14 is locked to clamp the sheet metal. The two clamping columns 12 can move up and down within the lifting clamping block 10 and are locked in place by the side locking knob 13. This changes the clamping height of the lower end of the clamping column 12 to accommodate the clamping of sheet metal parts of different heights. At the same time, the clamping position of the clamping column 12 is also changed by the rotation of the mounting plate 3 and the front and rear sliding and rotating mounting plate 5 to accommodate the clamping of sheet metal parts of different shapes.
