[0026] The positioning device can only be positioned at a certain point on the exterior surface of the front and rear bumpers of the car. The contact area between the positioning device and the front and rear bumpers of the car is small, making it difficult to ensure the stability of the front and rear bumpers of the car after positioning. During the cutting process, the front and rear bumpers of the car are prone to relative movement, affecting the normal progress of the cutting process. Figures 1 to 3 As shown, a cutting and positioning device for front and rear bumpers of an automobile is proposed, comprising a working platform 1, a mounting platform 2 is vertically mounted on the rear side of the upper surface of the working platform 1, a cutting unit is arranged in the middle of the mounting platform 2, and the front and rear bumpers of the automobile are cut and processed by the cutting unit, a cylinder 19 is mounted on the top of the mounting platform 2, and the output end of the cylinder 19 is connected to the cutting unit, and the cylinder 19 is a self-locking cylinder commonly used in the existing market, and its output end can stay at any position and lock, which will not be described in detail here, and the cylinder 19 is opened to cause the cutting unit to adjust its position in the vertical direction, so as to cause the cutting unit to approach or move away from the front and rear bumpers of the automobile, thereby realizing flexible cutting processing of the front and rear bumpers of the automobile; two groups of supporting components are symmetrically arranged on the left and right sides of the upper surface of the mounting platform 2, and each group of supporting components is arranged on the front side A positioning unit is provided, and the connection support between the positioning unit and the mounting platform 2 is realized by a supporting component. The positioning unit includes a shell 5, and the supporting component includes a first supporting seat 3 installed on the upper surface of the mounting platform 2. A first supporting rod 4 is installed on the front side of the outer wall of the first supporting seat 3, and the first supporting rod 4 is connected to the rear side of the outer wall of the shell 5. Through the setting of the first supporting rod 4, the shell 5 can be stably installed on the outer wall of the first supporting seat 3; a groove body 6 is opened on the outer wall of the shell 5 from left to right, and a positioning component is rotatably arranged in the inner cavity of the groove body 6. A driving component is arranged on the top of the shell 5, and the driving component is used to promote the positioning component to adjust the rotation angle and position it, and the front and rear bumpers of the car with different curvature facades are positioned by adjusting the angle of the positioning component.

[0027] See also Figure 2As shown, the positioning assembly includes a rotating shaft 13 rotatably installed on the inner wall of the groove body 6 from front to rear through a bearing, and also includes a connecting seat 7 fixedly installed on the outer wall of the rotating shaft 13, a connecting plate 8 is vertically installed on the bottom end of the outer wall of the connecting seat 7, and a clamping plate 9 is installed on the bottom end of the outer wall of the connecting plate 8. Through the rotation of the connecting plate 8, the clamping plate 9, the connecting seat 7 and the rotating shaft 13 can be driven to rotate synchronously to realize the adjustment of the inclination angle of the clamping plate 9, and a sliding groove 10 is opened on the outer wall of the connecting plate 8 from front to rear.

[0028] See also Figure 2 As shown, the driving assembly includes a rotating seat 16 rotatably mounted on the upper surface of the shell 5 through a bearing, a screw 17 is threadedly connected to the inner cavity of the rotating seat 16, a driving seat 12 is installed at the bottom end of the outer wall of the screw 17, and a moving pin 11 is rotatably connected to the bottom end of the driving seat 12, and the moving pin 11 is slidably embedded in the inner cavity of the slide groove 10. The rotating seat 16 is rotated in situ to cause the screw 17 to move vertically along the shell 5 to adjust the vertical positions of the driving seat 12 and the moving pin 11. When the moving pin 11 moves along the inner cavity of the slide groove 10, it can cause the connecting plate 8 and the connecting seat 7 to rotate around the rotating shaft 13 to adjust the angle of the clamping plate 9; the outer wall of the screw 17 A limit block 14 is fixedly installed on the wall, and a limit slot 15 is provided on the inner wall of the slot body 6 in the vertical direction, and the limit block 14 is slidably embedded in the inner cavity of the limit slot 15. By moving the limit block 14 along the inner cavity of the limit slot 15 set in the vertical direction, it can be ensured that the screw rod 17 moves in the vertical direction without rotating, thereby realizing the vertical movement and adjustment of the screw rod 17 by driving the rotating seat 16; in addition, in order to facilitate the rotation of the rotating seat 16, a number of handles 18 are equidistantly arranged on the side wall of the rotating seat 16. In the present embodiment, four handles 18 are arranged. By driving the handle 18 to rotate, the rotating seat 16 can be driven to rotate more conveniently and quickly.

[0029] The specific steps for adjusting the positioning angle of the splint 9 are as follows: the driving handle 18 drives the rotating seat 16 to rotate, prompting the screw 17 to move upward along the inner cavity of the rotating seat 16. At this time, the limit block 14 installed at the bottom end of the outer wall of the screw 17 moves upward along the inner cavity of the limit groove 15, so as to prompt the driving seat 12 at the bottom end of the screw 17 to drive the moving pin 11 to slide along the inner cavity of the slide groove 10.

At this time, the splint 9 rotates synchronously with the connecting plate 8 to adjust the inclination angle of the splint 9, so that the lower surface of the splint 9 fits the outer wall of the front and rear bumpers of the car for large-area positioning.

[0030] See also Figure 1 and Figure 3As shown, the cutting unit includes a second support seat 20 installed at the output end of the cylinder 19, a motor 21 is installed on the rear side of the outer wall of the second support seat 20, the output end of the motor 21 is connected to the drive shaft 22 through a coupling, and a cutting disk 23 is installed on the front side of the outer wall of the drive shaft 22. The cylinder 19 is opened to adjust the position of the second support seat 20, the motor 21, the drive shaft 22 and the cutting disk 23 in the vertical direction, so as to make the cutting disk 23 approach or move away from the front and rear bumpers of the automobile, thereby realizing flexible cutting processing of the front and rear bumpers of the automobile. It is worth mentioning that the second support seat 20, the motor 21, the drive shaft 22 and the cutting disk 23 are all commonly used equipment for existing automobile cutting processing, which can meet the use requirements, and their models are not limited or elaborated here.

[0031] See also Figure 3 As shown, a second support rod 24 is vertically installed on the front side of the outer wall of the second support seat 20, and a protective shell 25 is installed on the front side of the second support rod 24. The protective shell 25 is sleeved on the outer wall of the cutting disk 23, and the drive shaft 22 extends to the front side into the inner cavity of the protective shell 25. Through the arrangement of the second support rod 24 and the protective shell 25, the outside of the cutting disk 23 can be protected. Under the premise that the cutting disk 23 operates normally, the safety hazard caused by the cutting disk 23 during the cutting operation can be avoided, and at the same time, the excessive upward scattering of debris generated during the cutting process can be avoided.

[0032] The working principle of the cutting and positioning device for front and rear bumpers of an automobile in this embodiment is as follows:

[0033] When the angle of the clamping plate 9 needs to be adjusted so as to fit the curved outer wall of the front and rear bumpers of the automobile, the driving handle 18 drives the rotating seat 16 to rotate, prompting the screw 17 to move upward along the inner cavity of the rotating seat 16. At this time, the limit block 14 installed at the bottom end of the outer wall of the screw 17 moves upward along the inner cavity of the limit groove 15, so as to prompt the driving seat 12 at the bottom end of the screw 17 to drive the moving pin 11 to slide along the inner cavity of the slide groove 10. The moving moving pin 11 prompts the connecting plate 8 and the connecting seat 7 to rotate around the rotating shaft 13. At this time, the clamping plate 9 follows the connecting plate 8 to rotate synchronously, so as to adjust the inclination angle of the clamping plate 9, so as to prompt the lower surface of the clamping plate 9 to fit the outer wall of the front and rear bumpers of the automobile for large-area positioning; by adjusting the two clamping plates 9 on both sides to different inclination angles respectively, the positioning requirements of the front and rear bumpers of the automobile with different inclination angles on the left and right sides are realized;

[0034] The driven shaft 22 and the cutting disc 23 are rotated by the turned-on motor 21, and the output end of the turned-on cylinder 19 moves downward, so that the second support seat 20, the motor 21, the driven shaft 22, and the cutting disc 23 move downward as a whole, so that the rotating cutting disc 23 gradually cuts the front and rear bumpers of the automobile;

[0035] In summary, compared with the single-point positioning method, the utility model adjusts the inclination angle of the splint 9 relative to the outer surface of the front and rear bumpers of the automobile to make the splint 9 better fit the front and rear bumpers of the automobile, so that the two form a stable positioning connection relationship, thereby ensuring the stability of the front and rear bumpers of the automobile during the cutting process, avoiding the problem of relative displacement of the front and rear bumpers of the automobile due to the poor stability of the single-point contact method, and effectively ensuring the normal and effective cutting process of the front and rear bumpers of the automobile.

[0036] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
