[0023] The following will be combined with the drawings in 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] like Figure 1 and Figure 2 As shown, the utility model provides an electric vehicle rear axle grinding processing equipment, including a support frame 1, two rotating sleeves 4 are rotatably arranged on both sides of the support frame 1, the two rotating sleeves 4 are symmetrically arranged, and the rotating sleeve 4 is rotatably connected to the support frame 1 through bearings. The bearings make the rotation of the rotating sleeve 4 more stable and at the same time make the rotation of the rotating sleeve 4 more flexible, reducing the friction between the support frame 1, and a rotating rod 3 is arranged in the rotating sleeve 4, and the rotating sleeve 4 is threadedly connected to the rotating rod 3, and four connecting rods 21 are fixedly installed on the rotating rod 3, and the locking wheel 2 is connected to the rotating rod 3 through the four connecting rods 21. The rotating rod 3 is moved to one end close to the fixed block 7 by rotating the locking wheel 2, and the rotation direction at this place is opposite to the rotation direction of the thread. A hand wheel 5 is fixedly installed on the rotating sleeve 4, and the rotating sleeve 4 is driven to rotate by rotating the hand wheel 5. The rotation direction at this place is opposite to the rotation direction of the thread, and the rotating sleeve 4 drives the rotating rod 3 to rotate.

[0026] Further, such as Figure 3 As shown, the end of the rotating rod 3 is provided with a top head 31 which cooperates with the limit block 6. The side opposite to the top head 31 and the limit block 6 is a plane. The rotating locking wheel 2 drives the rotating rod 3 to rotate into the rotating sleeve 4, so that the rotating rod 3 moves toward the end close to the fixed block 7. The movement of the rotating rod 3 drives the top head 31 to move, so that the top head 31 can push the limit block 6 to move, and the two ends of the rear axle are clamped to fix the rear axle. When the rear axle needs to be rotated, the rear axle is rotated by turning the hand wheel 5, so that the operator can easily turn the rotating sleeve 4 to adjust the grinding position of the rear axle of the electric vehicle, so as to facilitate the grinding.

[0027] Among them, Figure 4 and Figure 5 As shown, a fixed block 7 is fixedly provided at the end of the rotating sleeve 4, and a limit block 6 is slidably provided on the fixed block 7. A sliding groove 71 is opened on the fixed block 7, and the limit block 6 slides in the sliding groove 71. The sliding groove 71 is an arc-shaped structure, and the height of the arc-shaped structure is greater than the height of the limit block 6 near the fixed block 7. The height of the arc-shaped structure at this location is as shown in FIG. Figure 4The height indicated by the arrow shown in the figure enables the limit block 6 to slide in the sliding groove 71. The limit block 6 is provided with an inclined surface 62, and the inclined surface 62 cooperates with the plane of the top head 31. The rotating rod 3 pushes the top head 31 to approach the limit block 6, and the top head 31 pushes the limit block 6 to move away from the center of the fixed block 7. The plane opened by the top head 31 can be tightly pressed against the inclined surface 62, so that the top head 31 can more easily push the limit block 6 to move. The cross-sections at both ends of the limit block 6 are semicircular structures. The cross-sectional area of ​​the end of the limit block 6 close to the fixed block 7 is smaller than the cross-sectional area away from the fixed block 7, so that a plug-in groove can be formed between the two limit blocks 6. The plug-in groove accommodates the top head 31, so that the rotating rod 3 can more easily push the limit block 6 to move, and the top head 31 is inserted Into the insertion slot, then move, squeeze the limit block 6, the limit block 6 moves away from the center of the fixed block 7, and the two ends of the rear axle are clamped, so that the rear axle is connected to the rotating rod 3. A number of rubber strips 61 are provided on the limit block 6. The rubber strips 61 can increase the friction between the limit block 6 and the rear axle when the limit block 6 is inserted into the two ends of the rear axle, so that the connection between the rear axle and the rotating rod 3 is more stable, and the possibility of sliding of the rear axle of the electric vehicle during the grinding process is reduced. There are two limit blocks 6, and a number of springs 8 are fixedly installed between the two limit blocks 6. The spring 8 makes the movement of the limit block 6 more stable. At the same time, when the rotating rod 3 moves away from the fixed block 7, the limit block 6 is released from the clamping of the rear axle under the action of the elastic force of the spring 8.

[0028] Embodiment 2:

[0029] Based on the above-mentioned embodiment 1, a rotating wheel is fixedly installed on the rotating sleeve 4, and the rotating wheel is connected to the motor through a belt. By driving the motor to rotate, the output shaft of the motor drives the belt to rotate, and the belt drives the rotating wheel to rotate. The rotating wheel drives the rotating sleeve 4 to rotate, so that the internal rotating rod 3 drives the rear axle to rotate, so that the rear axle can be polished more conveniently, thereby improving the polishing accuracy and efficiency.

[0030] Working principle: First, place both ends of the rear axle of the electric vehicle on the support frame 1, insert the limit blocks 6 into the two ends of the rear axle of the electric vehicle, then rotate the locking wheel 2 to make the rotating rod 3 move in the direction close to the rear axle of the electric vehicle, and the top head 31 on the rotating rod 3 is inserted between the two limit blocks 6, and continue to rotate the locking wheel 2 so that the top head 31 hits the limit blocks 6, so that the two limit blocks 6 move in the direction close to the inner wall of the rear axle of the electric vehicle until the rubber strip 61 on the limit blocks 6 contacts the inner wall of the rear axle of the electric vehicle, stop rotating the locking wheel 2, so that the rotating rod 3 is connected to the rear axle of the electric vehicle, then, the rotating sleeve 4 and the rotating rod 3 are driven to rotate by rotating the hand wheel 5 (the rotating sleeve 4 and the rotating rod 3 can also be driven to rotate by the driving motor), and the rotating rod 3 drives the rear axle of the electric vehicle to rotate, which is convenient for grinding the rear axle of the electric vehicle, so that the grinding accuracy and efficiency are improved;

[0031] After the grinding is completed, the locking wheel 2 is rotated in the opposite direction, and the rotating rod 3 moves away from the rear axle of the electric vehicle. The rotating rod 3 drives the top head 31 to move, so that the top head 31 releases the fixation of the limit block 6. Under the action of the two springs 8, the two limit blocks 6 approach each other and contact the fixation of the limit blocks 6 on the rear axle of the electric vehicle, and the polished rear axle of the electric vehicle is taken out from the support frame.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
