[0030] 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.

[0031] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of an electric vehicle frame parts processing fixture, comprising a base 1, a first mounting block 8 fixedly connected to the top left side of the base 1, and a second mounting block 10 fixedly connected to the top right side of the base 1. A fourth-axis rotary table 9 is mounted on both the left side of the second mounting block 10 and the right side of the first mounting block 8. A mounting plate 15 is provided in the middle of the fourth-axis rotary table 9. The mounting plate 15 facilitates subsequent processes. A quick-clamping exchange plate 14 is mounted at the top center of the mounting plate 15, enabling quick clamping and exchange of the exchange plate. The installation of 14 allows the fixing clamp 12 to be quickly replaced. The top left and right ends of the quick clamping exchange plate 14 are equipped with fixing clamps 12. The rear side of the top of the fixing clamp 12 is equipped with a connecting block 13. The left and right sides of the fixing clamp 12 are equipped with fixing mechanisms 2. The fixing mechanisms 2 are used to fix the fixing clamp 12. The front side of the base 1 is equipped with a slot plate 7. The inside of the slot plate 7 is equipped with a notice board 5. The four corners of the front side of the slot plate 7 are slidably connected with fixing rods 6. The installation of fixing rods 6 makes the slot plate 7 more stable.

[0032] Specifically, during the processing, first ensure that the two fourth-axis rotary tables 9 are installed securely. Then, place and firmly fix the mounting plate 15. Next, place the required electric vehicle frame accessories inside the fixing fixture 12 and ensure that they are firmly engaged for subsequent processing. When the fixing fixture 12 needs to be replaced, simply remove the quick-clamping exchange plate 14 and replace it. By installing the warning sign 5, the staff can be reminded, thereby reducing errors. Through the above procedures, the electric vehicle frame accessories can be quickly clamped, thus significantly improving work efficiency.

[0033] Reference Figure 1 , Figure 3 and Figure 5The fixing mechanism 2 includes two connecting rods 204, which are rotatably connected to the left and right ends of the fixing clamp 12 respectively. A pulley 201 is fixedly connected to the opposite side of the two connecting rods 204. A connecting rope 205 is fixedly connected to the top of the pulley 201. A connecting round rod 207 is fixedly connected to the top of the connecting rope 205. The installation of the connecting round rod 207 allows the top of the fixing clamp 12 to be lifted upward. The adjacent sides of the two connecting round rods 207 are fixedly connected to the top left and right sides of the fixing clamp 12 respectively. A limiting round plate 206 is fixedly connected to the opposite side of the two connecting round rods 207. A connecting round plate 202 is fixedly connected to the opposite side of the two pulleys 201. A locking rod 203 is slidably connected to the bottom of the connecting round plate 202. A turntable 3 is fixedly connected to the opposite side of the two connecting round plates 202. The installation of the turntable 3 facilitates the rotation of the connecting round plate 202.

[0034] Specifically, when processing electric vehicle parts of different sizes, first rotate the turntable 3 counterclockwise to make the connecting plate 202 start to rotate synchronously, which in turn drives the pulley 201 to rotate. At the same time, loosen the connecting rope 205 wrapped around the outside of the pulley 201, and you can lift the top of the fixing clamp 12 and place the electric vehicle frame parts inside it. Then, lower the top of the fixing clamp 12 and continue to rotate the turntable 3 so that the connecting rope 205 is rewound to the outside of the pulley 201. Since the connecting rod 207 is connected to the top of the fixing clamp 12, it can clamp different electric vehicle frame parts.

[0035] Reference Figure 1 , Figure 2 and Figure 3 The bottom four corners of the second mounting block 10 are all threaded with screws 11, and the bottom four corners of the base 1 are all fixedly connected with corner guards 4.

[0036] Specifically, the installation of screw 11 makes the second mounting block 10 more secure, and the installation of corner protectors 4 prevents damage to the base 1.

[0037] Working principle: During the processing, the two fourth-axis rotary tables 9 are first installed, and then the mounting plate 15 is placed and installed securely. The electric vehicle frame parts to be installed are placed inside the fixing fixture 12, which can then be clamped in place for easy subsequent processing. When the fixing fixture 12 needs to be replaced, the quick clamping exchange plate 14 can be removed and replaced. The installation of the warning sign 5 helps to remind the workers and reduce the occurrence of errors. Through the above process, the electric vehicle frame parts can be quickly clamped, thereby improving work efficiency.

[0038] When dealing with electric vehicle parts of different sizes, first rotate the turntable 3 in the opposite direction to make the connecting plate 202 start to rotate synchronously, which in turn makes the pulley 201 rotate as well. Then, loosen the connecting rope 205 wrapped around the outside of the pulley 201, and then lift the top of the fixing clamp 12. Then, place the electric vehicle frame part inside it, and then lower the top of the fixing clamp 12 and start rotating the turntable 3. Then, rewrap the connecting rope 205 around the outside of the pulley 201. Since the connecting rod 207 is connected to the top of the fixing clamp 12, the electric vehicle frame part can be clamped.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
