DETAILED DESCRIPTION

[0028] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] A cutting device for lamp housing processing, such as Figure 1 As shown, it includes a mounting frame 1, a support plate 2, a connecting plate 3, a placement plate 4, a cutting mechanism 5 and a rotating mechanism 6. Support plates 2 are welded to the upper sides of the left and right parts of the mounting frame 1, a connecting plate 3 is welded between the upper parts of the support plates 2, the middle part of the mounting frame 1 is rotatably connected to the placement plate 4, the connecting plate 3 is provided with a cutting mechanism 5, and the mounting frame 1 is provided with a rotating mechanism 6.

[0030] like Figure 1 and Figure 2 As shown, the cutting mechanism 5 includes a driving member 51, a rotating frame 52, a rotating member 53 and a laser cutting knife 54. The driving member 51 is connected to the middle part of the connecting fixed plate 3. The output shaft of the driving member 51 is rotatably connected to the rotating frame 52 through a connecting member. The lower part of the rotating frame 52 is rotatably connected to the rotating member 53, and the rotating member 53 is connected to the laser cutting knife 54.

[0031] When using the present invention, first place the mounting bracket 1 in the cutting area of ​​the lamp housing, and then place the lamp housing on the placement plate 4. After placement, according to the position of the lamp housing that needs to be cut, rotate and adjust the angle of the rotating bracket 52 and the rotating member 53, and then adjust the angle of the laser cutting knife 54. After the adjustment, start the driving member 51 on the connecting fixed plate 3 to drive the rotating bracket 52 and the rotating member 53 to rotate, so that the laser cutting knife 54 rotates, and adjust the direction of the laser cutting knife 54 so that the laser cutting knife 54 cuts the position of the lamp housing that needs to be cut, thereby playing the role of being able to adjust the angle and direction of the laser cutting knife 54 to facilitate cutting different parts of the lamp housing. The rotating mechanism 6 is used to control the rotation of the placement plate 4.

[0032] like Figure 1 and Figure 3 As shown, the rotating mechanism 6 includes a fixed frame 61, a fixed plate 62, a motor 63, a connecting shaft 64, a spur gear 65 and a rack 66. The fixed frame 61 is connected to the inner side of the right part of the mounting frame 1, and the lower sides of the left and right parts of the mounting frame 1 are connected to the fixed plates 62. The fixed frame 61 is connected to the motor 63, and the connecting shaft 64 is connected to the output shaft of the motor 63. The fixed plates 62 are rotatably connected to the connecting shaft 64, and the left and right parts of the connecting shaft 64 are connected to the spur gears 65. The lower sides of the left and right parts of the placement plate 4 are connected to the racks 66, and the spur gears 65 are meshed with adjacent racks 66.

[0033] By using the rotating mechanism 6 of the device, the placement plate 4 can be controlled to rotate. When the cutting position of the lamp shell needs to be adjusted, the motor 63 on the fixing frame 61 can be started to drive the connecting shaft 64 to rotate on the fixing plate 62, so that the spur gear 65 rotates and meshes with the rack 66, driving the placement plate 4 to rotate, thereby enabling the lamp shell to rotate, thereby expanding the cutting range of the lamp shell by the laser cutting knife 54.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a clamping mechanism 7, which includes a first telescopic component 71, a movable frame 72, a top block 73 and a rocker rod 74. The first telescopic component 71 is connected to the upper middle side of the placement plate 4, and the first telescopic component 71 is composed of a first telescopic rod and a first telescopic spring. Four movable frames 72 are slidably connected to the upper side of the placement plate 4, and the outer sides of the movable frames 72 are connected to the top blocks 73, and the movable frames 72 are rotatably connected to the first telescopic component 71 by rocker rods 74.

[0035] The clamping mechanism 7 of the device can be used to clamp the lamp housing. When the lamp housing is placed on the placement plate 4, the lamp housing squeezes the first telescopic rod in the first telescopic assembly 71 to contract, and the first telescopic spring contracts, causing the rocker arm 74 to rotate, pushing the movable frame 72 away from each other, so that the top block 73 contacts the inner wall of the lamp housing, thereby clamping and fixing the lamp housing to prevent the lamp housing from moving during cutting. After the lamp housing is cut, the lamp housing is moved upward, the first telescopic rod and the first telescopic spring rebound, driving the movable frame 72 to reset, so that the top block 73 is separated from the inner wall of the lamp housing for easy removal.

[0036] like Figure 1 and Figure 6 As shown, an auxiliary mechanism 8 is also included, and the auxiliary mechanism 8 includes a connecting frame 81, a guide frame 82, a moving block 83, a first spring 84 and a rotating rod 85. The upper sides of the front and rear parts of the mounting frame 1 are connected to the connecting frame 81, and the front and rear sides of the mounting frame 1 are connected to the guide frame 82. The moving blocks 83 are slidably connected to the guide frames 82. The left and right sides of the moving blocks 83 that are away from each other are connected to the first spring 84. The connecting frame 81 is rotatably connected to the rotating rod 85, and the rotating rod 85 is rotatably connected to the adjacent moving blocks 83.

[0037] The auxiliary mechanism 8 of the device can be used to assist in fixing the lamp housing. When the placement plate 4 rotates, the squeezed moving block 83 retracts inward on the guide frame 82, and the first spring 84 is squeezed and contracted, so that the rotating rod 85 rotates on the connecting frame 81, pressing and limiting the lamp housing, thereby fixing the lamp housing during rotation and preventing the lamp housing from shifting. After the placement plate 4 is reset, the first spring 84 rebounds, driving the moving block 83 to reset, so that the rotating rod 85 is reset.

[0038] like Figure 1 and Figure 7 As shown, it also includes a clamping mechanism 9, which includes a support frame 91, a rotating ring 92, a second telescopic component 93 and a rotating ball 94. The support frames 91 are connected to the sides of the support plates 2 that are close to each other, the support frames 91 are rotatably connected to the rotating ring 92, the rotating ring 92 is connected to the second telescopic component 93, the second telescopic component 93 is composed of a second telescopic rod and a second telescopic spring, and the lower side of the second telescopic component 93 is rotatably connected to the rotating ball 94.

[0039] By using the clamping mechanism 9 of the device, the lamp housing can be clamped. After the lamp housing is placed on the placement plate 4, the rotating ring 92 on the adjustment support frame 91 is rotated to drive the second telescopic component 93 to rotate, so that the rotating ball 94 contacts the lamp housing. When the lamp housing moves, the rotating ball 94 is pressed against the lamp housing by the second telescopic rod and the second telescopic spring in the second telescopic component 93, thereby clamping the lamp housing and preventing the lamp housing from detaching from the placement plate 4.

[0040] like Figure 1 and Figure 8 As shown, a locking mechanism 10 is also included, and the locking mechanism 10 includes a limiting block 101, a wedge frame 102, a second spring 103 and a connecting plate 104. Four limiting blocks 101 are connected to the upper side of the placement plate 4, and four connecting plates 104 are connected to the upper side of the placement plate 4. The connecting plates 104 and the limiting blocks 101 are both located outside the movable frame 72. The connecting plates 104 are slidably connected with wedge frames 102, and the lower sides of the wedge frames 102 are in contact with the placement plate 4. Two second springs 103 are connected between the wedge frames 102 and the connected connecting plates 104.

[0041] By using the locking mechanism 10 of the device, the lamp housing can be locked. When the lamp housing is placed on the placement plate 4, the lamp housing is located between the wedge frame 102 and the limit block 101, so that the lamp housing squeezes the wedge frame 102 to move inward on the connecting plate 104. Through the action of the second spring 103, the wedge frame 102 is always in contact with the lamp housing, thereby playing a role in locking the lamp housing and enhancing the stability of the lamp housing.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
