Moreover, the clamping structure is difficult to adapt to workpieces of different sizes and shapes, and the angle adjustment depends on experience without quantitative scale reference. Although there are adjustable clamps in the existing technology, they cannot simultaneously meet the requirements of high-precision angle positioning, rapid position adjustment and strong versatility. In view of this, there may be technical means to solve the above problems in the existing technology. However, this case aims to provide an alternative or replacement technical solution.

[0014] Beneficial effects

[0015] This utility model provides a fixing device for automotive parts production, which has the following advantages: This fixing device supports the rotation of the mounting shaft through a bearing seat, and achieves angle visualization with the help of a fixing ring and a scale ring. The positioning bolt presses the inner wall of the fixing ring to ensure stable locking of the clamping component at any angle. The second mounting bracket slides along the slide groove to adjust the spacing. Combined with the strip groove of the connecting adjustment structure and the connecting screw, the spacing of the mounting bracket can be finely adjusted and locked, adapting to workpieces of different sizes.

[0023] When fixing automotive parts during production, the workers first adjust the distance between the first mounting bracket 2 and the second mounting bracket 4 according to the specifications of the automotive parts, changing the position of the second mounting bracket 4 in the two sliding grooves 3. The distance between the second mounting bracket 4 and the first mounting bracket 2 is fixed by connecting the adjustment structure. Then, according to the specifications of the automotive parts, the position of the moving block 5 in the first mounting bracket 2 and the second mounting bracket 4 is precisely adjusted. Finally, the position of the moving block 5 is fixed by turning the fixing bolt 7 in the fixing bracket 6. Then, the positioning rod 12 on one side of the mounting shaft 9 is moved, causing the mounting shaft 9 to rotate in the bearing seat 8 until one end of the positioning rod 12 corresponds to the specified scale on the upper end of the scale ring 11. Finally, the positioning bolt 13 in the positioning rod 12 is turned until the bottom end of the positioning screw contacts the upper wall of the fixing ring 10, fixing the angle of the mounting shaft 9. This achieves the angle fixing of the clamping assembly. Finally, the workpiece is fixed by the clamping assembly.

[0024] In the specific implementation process, the clamping assembly includes: a clamping frame 14, a lead screw 15, and two clamping blocks 16;

[0025] The lower center of the clamping frame 14 is fixedly installed on the top of the mounting shaft 9. The two ends of the lead screw 15 are respectively embedded in the two side walls of the clamping frame 14 through bearings. The two clamping blocks 16 are respectively fitted on the upper two sides of the lead screw 15 and are located on the two sides inside the clamping frame 14.

[0026] When clamping and fixing the workpiece, place the workpiece above the clamping frame 14, and then turn the lead screw 15. With the internal thread of the lead screw 15 and the clamping block 16 engaged, the two clamping blocks 16 move synchronously towards the center until the workpiece is fixed on the upper end of the clamping frame 14.

[0027] In the specific implementation process, the connection adjustment structure includes: a first connecting plate 17, a second connecting plate 18, a strip groove 19, a connecting screw 20, and a connecting nut 21;

[0028] The first connecting plate 17 is fixedly installed on the side wall of the first mounting bracket 2, the second connecting plate 18 is fixedly installed at the center of the side wall of the second mounting bracket 4 and is located above the first connecting plate 17, the strip groove 19 is opened at the center of the upper end of the second connecting plate 18, the bottom end of the connecting screw 20 is fixedly installed on the upper end of the first connecting plate 17 and the top end is movable through the strip groove 19, and the connecting nut 21 is movably fitted on the upper end of the connecting screw 20.

[0029] When adjusting and fixing the position of the second mounting bracket 4, the connecting screw 20 can be moved within the slot 19 formed on the upper end of the second connecting plate 18, changing the overlap length between the second connecting plate 18 and the first connecting plate 17. After adjustment, the connecting nut 21 at the upper end of the connecting screw 20 is tightened until the bottom end of the connecting nut 21 contacts the upper wall of the second connecting plate 18. The position of the connecting screw 20 is fixed by the friction between the connecting nut 21 and the second connecting plate 18.

[0030] In the specific implementation process, the angle between the first mounting frame 2 and the second mounting frame 4 is 90 degrees. The first mounting frame 2 and the second mounting frame 4 are vertically distributed to form an L-shaped support structure, which takes into account both space utilization and torsional strength.

[0031] In the specific implementation process, the clamping block 16 and the lead screw 15 are connected by internal threads. The internal threads of the clamping block 16 are tightly engaged with the lead screw 15 to provide uniform clamping force and prevent loosening caused by processing vibration.

[0032] In the specific implementation process, the lead screw 15 adopts a bidirectional threaded lead screw. The bidirectional thread of the lead screw 15 drives the two clamping blocks 16 to move synchronously in opposite directions or in opposite directions.
