[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3 The utility model provides an embodiment: a positioning device for processing metal inserts of new energy vehicles, including a workbench 1, the top of the outer wall of the workbench 1 is fixedly connected to an electric slide rail 2, and the inner wall of the electric slide rail 2 is slidably connected to a movable plate 4. The electric slide rail 2 is a prior art, and a driving motor is provided inside it. The driving motor can control the movable plate 4 to move up and down inside it, so that it can contact the metal insert of the automobile, thereby grinding it. A positioning component 3 is provided on the inner wall of the top of the workbench 1.

[0032] Reference Figure 2 = Figure 3 The positioning assembly 3 includes a sliding block 31. Two sets of guide grooves are provided on the surface of the workbench 1. The sliding block 31 is slidably connected to the inner wall of the guide groove of the workbench 1. The bottom end of the sliding block 31 is I-shaped, and the vertical part of its surface fits with the guide groove on the surface of the workbench 1, so that the sliding block 31 can only move back and forth on the inner wall of the workbench 1. The sliding block 31 is provided with two groups. The bottom ends of the outer walls of the two groups of sliding blocks 31 are hinged with sliding rods 32. The sliding rods 32 hinged at the bottom ends of the two groups of sliding blocks 31 are obliquely diagonally corresponding. The outer wall of the sliding rod 32 away from the sliding block 31 is slidably connected to the connecting rod 33. The inner wall of the connecting rod 33 slides with two sets of sliding rods 32, so that one group of sliding rods 32 is inclined. When the inner wall of the connecting rod 33 moves, the other set of sliding rods 32 will also move on the inner wall of the connecting rod 33. The outer wall of the top of the sliding block 31 is elastically connected to the arc plate 36 through a limit spring 35. One end of the limit spring 35 is fixedly connected to the right outer wall of the arc plate 36, and the other end of the limit spring 35 is fixedly connected to the inner side wall of the sliding block 31. The function of the limit spring 35 is to apply an elastic support to the arc plate 36 when the arc plate 36 contacts the automobile metal insert. The right outer wall of the arc plate 36 is fixedly connected to the moving rod 34. By setting the moving rod 34, the position of the arc plate 36 after contact and movement is guided to avoid tilting.

[0033] Reference Figure 2-Figure 3The wedge block 38 passes through and is slidably connected to the inner wall of the left sliding block 31 through a return spring 37. The inner wall of the bottom end of the left sliding block 31 is elastically connected to a wedge block 38 by a return spring 37. The bottom end of the left sliding block 31 is provided with a connecting block, and the connecting block part slides on the surface of the workbench 1. The moving rod 34 passes through and is slidably connected to the inner wall of the sliding block 31. One end of the return spring 37 is fixedly connected to the inner wall of the left sliding block 31, and the other end of the return spring 37 is fixedly connected to the surface of the wedge block 38. The return spring 37 acts to automatically return to its position after the inclined surface of the wedge block 38 is squeezed and moved. The surface of the workbench 1 is provided with multiple groups of card slots, and the wedge block 38 is engaged with the inner wall of the card slot. The engagement between the two fixes the sliding block 31 in the position moved by the inner wall of the workbench 1, so that metal inserts of different sizes can be adjusted and fixed. The surface of the movable plate 4 is provided with a grinding assembly 5.

[0034] Reference Figure 1 and Figure 4 The grinding assembly 5 includes a motor 51, the output shaft of the motor 51 is fixedly connected to a rotating sleeve 52, the motor 51 is fixedly connected to the top of the outer wall of the moving plate 4, the rotating sleeve 52 is rotatably connected to the bottom end of the outer wall of the moving plate 4, the top of the inner wall of the rotating sleeve 52 is elastically connected to the sliding sleeve 54 through a connecting spring 53, one end of the connecting spring 53 is fixedly connected to the top of the inner wall of the rotating sleeve 52, and the other end of the connecting spring 53 is fixedly connected to the top of the outer wall of the sliding sleeve 54. The function of the connecting spring 53 is to automatically reset the position of the sliding sleeve 54 and the grinding head 57 after being squeezed and moved. The sliding sleeve 54 is slidably connected to the inner wall of the rotating sleeve 52, and the inner wall of the bottom end of the rotating sleeve 52 is elastically connected to the sliding sleeve 54. The wall is provided with a guide groove that fits the bottom end of the sliding sleeve 54, so that the sliding sleeve 54 can only move up and down on the inner wall of the rotating sleeve 52 and cannot separate from its inner wall. The rotating sleeve 52 passes through and is rotatably connected to the inner wall of the top of the shielding cover 55. The bottom end of the outer wall of the sliding sleeve 54 is detachably mounted with a grinding head 57 through a bolt 56. The bolt 56 can be removed by a special tool, so that the grinding head 57 can be easily disassembled and replaced, and the burrs of the metal inserts can be polished by rotating the grinding head 57. The bottom end of the outer wall of the movable plate 4 is fixedly connected to the shielding cover 55. By providing the shielding cover 55, the debris generated by the grinding head 57 during grinding is blocked.

[0035] Working principle: Place the automotive metal insert that needs to be polished on the surface of the workbench 1, and then directly push the left sliding block 31. The left sliding block 31 moves forward along the guide groove of the workbench 1. At this time, the sliding rod 32 hinged to the left sliding block 31 pushes the connecting rod 33 to move. At the same time, the other set of sliding rods 32 hinged to the right sliding block 31 also moves in the connecting rod 33, thereby driving the right sliding block 31 to move synchronously, so that the two sets of sliding blocks 31 can be relatively close or away to adapt to metal inserts of different sizes. In this process, the curved plate 36 will contact the metal inserts. The insert contacts and the metal insert is elastically supported and fixed under the elastic action of the limit spring 35. At the same time, the moving rod 34 guides the movement of the arc plate 36. At the same time, when the left sliding block 31 moves, the wedge block 38 will disengage from the slot at the current position of the workbench 1 and be squeezed by its inner wall, allowing it to move outward and allowing the return spring 37 to be elastically acted upon until the two sets of arc plates 36 clamp and fix the workpiece. At the same time, the wedge block 38 is engaged with the slot on the surface of the workbench 1 under the action of the return spring 37, thereby fixing the position of the left sliding block 31 after movement.

[0036] In the grinding assembly 5, motor 51 starts to rotate rotating sleeve 52, which in turn drives sliding sleeve 54 and grinding head 57. When grinding head 57 contacts the metal insert for grinding, it is squeezed and moves upward, driving sliding sleeve 54 upward within rotating sleeve 52, compressing connecting spring 53. Connecting spring 53 provides a reset force. Debris generated during the grinding process is blocked by shield 55 to prevent it from flying around. If the grinding head 57 needs to be replaced, it can be replaced by removing bolt 56 using a dedicated tool. This series of actions achieves the positioning and grinding of metal inserts for new energy vehicles.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
