Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please refer to Figure 1-6 As shown, this utility model provides an automotive parts processing fixture, including a base 1. The top of the base 1 has a groove 3, and a rotary table 4 is rotatably connected to its inner side. The bottom of the rotary table 4 is connected to a drive mechanism to facilitate its rotation. A fixed seat 10 is installed on the top of the rotary table 4. Two sets of slides 13 are slidably connected to the inner side of the fixed seat 10 and are connected to the fixed seat 10 through an adjustment mechanism to facilitate the adjustment of their spacing. The top of each set of slides 13 is provided with a positioning block 14. A V-shaped slot 15 is provided on the opposite side of each set of positioning blocks 14. An auxiliary fixing mechanism is provided above each set of slots 15.

[0023] Specifically, the drive mechanism can drive the rotary table 4 to rotate, thereby adjusting the angle of the fixed seat 10 and the automotive parts. The adjustment mechanism can drive the two sets of slide blocks 13 to slide inside the fixed seat 10 to adjust the spacing, so that the V-shaped slots 15 of the two sets of positioning blocks 14 can clamp parts of different sizes. The auxiliary fixing mechanism can press the parts from above to achieve multi-angle adjustable clamping. Thus, through the above structure, multi-angle adjustment and adaptive clamping of automotive parts of different sizes can be achieved, improving processing accuracy and efficiency. The structure is compact and easy to operate.

[0024] The adjustment mechanism includes a second motor 12. A bidirectional screw 11 is rotatably connected to the inner side of the fixed base 10. One end of the bidirectional screw 11 is connected to the output end of the second motor 12 installed on one side of the fixed base 10. Two sets of slide blocks 13 are threadedly connected to the bidirectional screw 11. Slider blocks 22 are provided at both ends near the bottom. Slide grooves 21 are provided on both sides of the fixed base 10 to facilitate the sliding of the sliders 22. By starting the second motor 12, it can drive the bidirectional screw 11 to rotate inside the fixed base 10. Since the two sets of slide blocks 13 are respectively engaged with the two reverse threads of the bidirectional screw 11, and the sliders 22 slide along the slide grooves 21 of the fixed base 10, the two sets of slide blocks 13 can move synchronously towards or away from each other. This can drive the V-shaped slot 15 of the positioning block 14 to quickly adjust the clamping distance to adapt to parts of different sizes. Thus, by setting it up, the clamping distance can be quickly and accurately adjusted to adapt to parts of different sizes, improving clamping efficiency and stability.

[0025] The auxiliary fixing mechanism includes a pressure plate 20, a vertical rod 16 rotatably connected to the top of the positioning block 14, a top plate 17 at the top of the vertical rod 16, and a screw 18 threadedly connected to the top plate 17. One end of the screw 18 is connected to a rocker arm 19, and the other end is rotatably connected to the pressure plate 20. By rotating the rocker arm 19, the screw 18 can rotate and rise on the top plate 17. The bottom end of the screw 18 can push the pressure plate 20 to move up and down along the vertical rod 16. When the part is placed in the V-shaped slot 15, the pressure plate 20 presses down to hold the top of the part. Together with the positioning block 14, it can form a three-point clamping, which enhances the fixing stability. Thus, by setting it up, it can effectively prevent the part from shifting during processing, and significantly improve the clamping stability and processing accuracy.

[0026] Rubber buffer pads are provided on the inner side of the slot 15 and the bottom of the pressure plate 20. The rubber buffer pads can prevent scratches on the surface of the parts, while increasing the friction to avoid slipping, thus taking into account both protection and clamping stability.

[0027] The drive mechanism includes a first motor 8. A transmission chamber 5 is located on the top inner side of the base 1, and a maintenance cover 9 is installed at the bottom of the chamber. A rotating shaft is rotatably connected to the inner side of the groove 3. One end of the rotating shaft is connected to the rotary table 4, and the other end extends to the inner side of the transmission chamber 5 and is connected to a worm gear 6. The worm gear 6 meshes with a worm 7 rotatably connected to the inner side of the transmission chamber 5. One end of the worm 7 is connected to the output end of the first motor 8 installed on one side of the transmission chamber 5. After the first motor 8 is started, it can drive the worm 7 to rotate. The worm 7 meshes with the worm gear 6, which can drive the rotating shaft, which is coaxial with the worm gear 6, to rotate in the groove 3. This can drive the rotary table 4 and the fixed seat 10 to rotate as a whole, so as to achieve precise adjustment of the processing angle. The maintenance cover 9 facilitates the maintenance of the worm gear and worm in the transmission chamber 5. Thus, by setting it up, the rotary table 4 can be rotated smoothly and accurately. The maintenance cover 9 makes maintenance more convenient and ensures long-term reliable operation.

[0028] The base 1 has mounting holes 2 at each of its four corners for fixing to the processing equipment. The mounting holes 2 facilitate the quick fixing of the fixture to the processing equipment, ensuring the stability of the fixture during the processing and improving the efficiency of assembly and disassembly.

[0029] Working principle: First, the fixture can be fixed to the processing equipment through the mounting holes 2 at the four corners of the base 1. Then, the workpiece to be processed is placed in the V-shaped slots 15 of the two sets of positioning blocks 14. After starting the second motor 12, it can drive the bidirectional screw 11 to rotate. Since the two sets of slide blocks 13 are respectively engaged with the two reverse threads of the bidirectional screw 11, and simultaneously the slider 22 slides along the slide groove 21 of the fixed base 10, the two sets of slide blocks 13 can move synchronously towards each other, thereby driving the V-shaped slots 15 of the positioning blocks 14 to move quickly. Adjust the clamping distance to accommodate parts of different sizes, then rotate the rocker arm 19, which can drive the screw 18 to rotate and descend on the top plate 17. The bottom end of the screw 18 can push the pressure plate 20 down along the upright 16 to form a three-point clamping with the V-shaped slot 15. During processing, the first motor 8 can drive the worm gear 7 and worm wheel 6 to drive the rotary table 4 to rotate to the required processing angle. The inspection cover plate 9 can maintain the transmission components at any time, thereby realizing the fast and accurate clamping and processing of parts of multiple angles and sizes, and thus completing the entire operation process.

[0030] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
