AI Technical Summary
The edge cutting device of the existing automobile roof sunroof side pad is prone to slip up and down due to the transition section being too smooth during the edge cutting process, causing the edge cutting knife to slip up and down, causing deviation.
An edge cutting device including placing a box, a transition section and an edge cutting knife is designed. A tool groove with a transverse circumference is opened on the top wall of the transition section. The edge cutting knife moves horizontally along the groove, and is limited by the upper and lower direction of the groove to avoid up and down deviation.
By moving the edge cutting knife horizontally along the groove ring, we ensure that the edge cutting knife will not shift up and down during the edge cutting process, improving the edge cutting accuracy and stability.

DETAILED DESCRIPTION
[0017] The invention of the utility model is further described in detail below in conjunction with specific implementation methods.
[0018] like Figure 1 As shown, the trimming device of the utility model comprises a placing frame 1, and a surrounding area 3 surrounded by the placing frame 1 is provided with left and right transverse tracks 4, and the left and right transverse tracks 4 are provided with front and rear transverse tracks 5 that can move along the left and right transverse tracks 4. Figure 2As shown, a base column 6 is mounted on the front and rear transverse rails 5 and can move along the base column 6. The upper part of the base column 6 can rotate horizontally relative to the lower part. A lever 7 with one end facing inward and the other end facing outward is mounted on the top wall of the base column 6. A vertical cylinder 14 is mounted on the inner side wall of the base column 6. The top end of the vertical cylinder 14 is connected to the inner end of the lever 7 ( Figure 2 The outward end of the lever 7 ( Figure 2 The connecting rod 8 is hingedly connected to the outer edge of the placing frame 1 (right end in the middle), and the connecting rod 8 only turns up and down around the hinge point when subjected to external force; the outer end of the connecting rod 8 is equipped with a trimming knife 9 placed obliquely downward and inward. The inner periphery of the placing frame 1 extends obliquely upward and inwardly to the transition section 2, and a knife groove 15 arranged transversely and circumferentially is provided on the top wall of the transition section 2. The knife groove 15 is obliquely depressed inwardly and is crossed by the outer end of the connecting rod 8. The trimming process is described in detail below.
[0019] like Figure 3 and Figure 4 As shown, the sunroof side cushion embedding portion 13 is in the shape of a square frame, which is inserted into the square frame-shaped transition section 2, and the sunroof side cushion pasting portion 12 is placed on the top wall of the placement square frame 1. A hinge column 11 is provided outside the placement square frame 1, and a lateral rotatable pressing block 10 is installed on the hinge column 11. The pressing block 10 is composed of Figure 1 Status turns to Figure 3 The sunroof side pad sticking portion 12 is pressed in this state. Figure 2 The vertical cylinder 14 in the state extends upward, the base column 6, the lever 7 and the connecting rod 8 together serve as the lever 7 mechanism, and are driven by the vertical cylinder 14 to turn downward around the top wall of the base column 6. The trimming knife 9 is driven by the lever 7 mechanism to turn downward until the knife head partially presses the sunroof side cushion embedding portion 13 located just above the knife groove 15 into the knife groove 15, that is, Figure 5 As shown, the cutting edge knife 9 is tilted downward and faces inward. Figure 3 As shown, the base column 6 moves forward along the front and rear transverse rails 5, driving the trimming knife 9 to move forward along the knife groove 15 to trim the right part of the sunroof side guard pad embedded part 13. When the trimming is moved forward to the right front corner, the base column 6 rotates 90 degrees counterclockwise to make a circumferential lateral rotation, and the trimming knife 9 follows the rotation of the base column 6 and moves to the front of the sunroof side guard pad embedded part 13 to cut off the remaining edge at the corner. Then the front and rear transverse rails 5 move left along the left and right transverse rails 4, and the trimming knife 9 follows the left movement to trim the front of the sunroof side guard pad embedded part 13. Similarly, the trimming knife 9 completes the circumferential lateral movement in this step, and accordingly cuts off the remaining uncut edge of the sunroof side guard pad embedded part 13, thus completing the trimming process. During the circumferential lateral movement, the left and right transverse rails 4 and the front and rear transverse rails 5 jointly serve as a mobile drive device.
