Description

Technical Field

[0001] The utility model relates to the technical field of skylight frame track cutting, in particular to a cutting device for processing automobile aluminum alloy skylight frames. Background Art

[0002] The car sunroof is installed on the roof, which can effectively circulate the air in the car, increase the intake of fresh air, and bring health and comfort to the car owner. At the same time, the car window can also broaden the field of vision, and is also often used for mobile photography and video shooting. Car sunroofs can be roughly divided into: sliding type, built-in type, built-in flip-out type, panoramic type and curtain type, etc., and are mainly installed on commercial SUVs, sedans and other models. The frame for installing the sunroof glass is composed of guide rails, which are essential components for the installation of car sunroofs. During the production process of the guide rails, they need to be cut.

[0003] At present, most of the guide rails in the market are cut by ordinary aluminum alloy metal cutting machines. However, due to the complex cross-sectional shape of the guide rails, for example, a car sunroof disclosed in the patent network (publication number: CN112428800A) includes a guide rail, a first start unit and a second start unit arranged on the guide rail; it can be seen from the attached drawings that there are multiple tracks in the guide rail, so one side is relatively complex. Therefore, it is not easy for ordinary metal cutting machines to fix the guide rails, which can easily cause the guide rails to shake during cutting, resulting in insufficient cutting accuracy, which brings inconvenience to the later assembly of the sunroof, and at the same time, it is easy to cause the glass to run poorly in the sunroof frame. For this reason, we propose a cutting device for processing the aluminum alloy sunroof frame of an automobile to solve the problem of insufficient cutting accuracy caused by unstable fixing. Utility Model Content

[0004] The utility model provides a cutting device for processing an automobile aluminum alloy sunroof frame, so as to solve the problems raised in the background technology.

[0005] In order to solve the above problems, the utility model provides a cutting device for processing automobile aluminum alloy sunroof frame, comprising a workbench, a transfer platform, an upper clamping mechanism, a lower clamping mechanism, and a cutting mechanism. A guide rail to be cut is placed on the workbench, a support frame is installed on the top of the workbench, and a plurality of fixing rods are arranged in the support frame. The upper clamping mechanism is composed of two first electric telescopic rods, and an upper positioning plate that abuts against the upper surface of the guide rail is threadedly installed in the telescopic end of the first electric telescopic rod. The upper clamping mechanism is fixedly installed in the fixing rod. The transfer platform is arranged on one side of the workbench, and an L-shaped fixing plate is fixedly arranged in a side surface of the workbench close to the transfer platform. The lower clamping mechanism is composed of two second electric telescopic rods, and The telescopic end of the second electric telescopic rod is threadedly installed with a lower positioning plate that abuts against the track on the lower surface of the guide rail. The lower clamping mechanism is fixedly installed in the L-shaped fixed plate. The cutting mechanism is installed in the support frame and is located above the lower clamping mechanism and the transfer platform. The cutting mechanism consists of a driving motor, a threaded rod, and a cutting knife. The driving motor is installed in a side surface of the support frame. The threaded rod is rotatably installed in the support frame and one end is connected to the power output shaft of the driving motor. A connecting block is threadedly connected in the threaded rod. A third electric telescopic rod is fixedly installed at the bottom of the connecting block. The telescopic end of the third electric telescopic rod is installed with a fixed frame. The cutting knife is installed in the fixed frame, and the cutting knife is connected to the cutting motor.

[0006] Preferably, an upper clamping mechanism symmetrical to the lower clamping mechanism is provided above the lower clamping mechanism.

[0007] Preferably, the upper positioning plate threadedly mounted in the first electric telescopic rod matches the size and shape of the upper surface of the guide rail.

[0008] Preferably, the lower positioning plate in the second electric telescopic rod matches the size and shape of the track on the lower surface of the guide rail.

[0009] Preferably, two guide rods are symmetrically arranged on both sides of the threaded rod in the support frame, and the connecting block in the cutting mechanism is slidably connected to the two guide rods.

[0010] The beneficial effects of adopting the above technical solution are:

[0011] 1. The upper surface of the guide rail placed on the workbench can be pressed and positioned by the upper clamping mechanism. Since the upper positioning plate is threadedly installed in the first electric telescopic rod, it is easy to replace so that the upper positioning plate can fit, contact and squeeze the upper surfaces of different guide rails.

[0012] 2. The lower positioning plate can be inserted into the track on the lower surface of the guide rail through the lower clamping mechanism for pressing and positioning. Since the lower positioning plate is threadedly installed in the second electric telescopic rod, it is easy to replace so that the lower positioning plate can fit, contact and squeeze the tracks on the lower surfaces of different guide rails.

[0013] 3. By symmetrically arranging an upper clamping mechanism on the lower clamping mechanism, the cutting position of the cutting mechanism is made more stable, so that the guide rail will not shake during cutting, thereby improving the cutting accuracy.

[0014] 4. The transfer table makes it easy to quickly remove the cut guide rails, and also supports the lower part of the guide rails, further improving the stability of the guide rails when the cutting mechanism is cutting. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1-3 In the present embodiment, a cutting device for processing an automobile aluminum alloy sunroof frame comprises a workbench 1, a transfer platform 2, an upper clamping mechanism 3, a lower clamping mechanism 4, and a cutting mechanism 5. A guide rail 6 to be cut is placed on the workbench 1, a support frame 11 is installed on the top of the workbench 1, and a plurality of fixing rods 12 are arranged in the support frame 11. The upper clamping mechanism 3 is composed of two first electric telescopic rods 31, and an upper positioning plate 32 that abuts against the upper surface of the guide rail 6 is threadedly installed in the telescopic end of the first electric telescopic rod 31, and the upper clamping mechanism 3 is fixedly installed in the fixing rod 12, the transfer platform 2 is arranged on one side of the workbench 1, and an L-shaped fixing plate 13 is fixedly arranged in a side surface of the workbench 1 close to the transfer platform 2, and the lower clamping mechanism 4 is composed of two second electric telescopic rods 41, and the telescopic end of the second electric telescopic rod 41 A lower positioning plate 42 is threadedly installed to abut against the track 61 on the lower surface of the guide rail 6. The lower clamping mechanism 4 is fixedly installed in the L-shaped fixing plate 13. The cutting mechanism 5 is installed in the support frame 11 and is located above the lower clamping mechanism 4 and the transfer platform 2. The cutting mechanism 5 consists of a driving motor 51, a threaded rod 52, and a cutting knife 53. The driving motor 51 is installed in a side surface of the support frame 11. The threaded rod 52 is rotatably installed in the support frame 11, and one end is connected to the power output shaft of the driving motor 51. A connecting block 54 is threadedly connected in the threaded rod 52. A third electric telescopic rod 55 is fixedly installed at the bottom of the connecting block 54. A fixed frame 56 is installed at the telescopic end of the third electric telescopic rod 55. The cutting knife 53 is installed in the fixed frame 56, and the cutting knife 53 is connected to the cutting motor 57.

[0023] Through the above technical solution, the guide rail 6 to be cut is placed on the workbench 1. When it is moved to the length required to be cut, one end of the guide rail 6 is located in the transfer platform 2. At this time, the first electric telescopic rod 31 in the upper clamping mechanism 3 installed in the plurality of fixed rods 12 moves downward, driving the upper positioning plate 32 to be pressed against the upper surface of the guide rail 6. The downward movement length of each of the two first electric telescopic rods 31 in the upper clamping mechanism 3 is controlled by an external controller to ensure that the upper positioning plate 32 is pressed against the upper surface of the guide rail 6 and does not cause overpressure on the upper surface of the guide rail 6. Through the plurality of upper clamping mechanisms 3, the guide rail 6 can be stably pressed into the workbench 1 to keep it stable. Synchronously, the second electric telescopic rod 41 in the lower clamping mechanism 4 installed through the L-shaped fixed plate 13 drives the lower positioning plate 42 to move upward and insert into the lower surface of the guide rail 6. The moving length of each of the two second electric telescopic rods 41 in the lower clamping mechanism 4 is controlled by an external controller to ensure that the lower positioning plate 42 contacts the inner surface of the inner track 61 on the lower surface of the guide rail 6. The guide rail 6 can be stably clamped by the upper clamping mechanism 3 and the lower clamping mechanism 4, and then the cutting mechanism 5 is cooperated to perform cutting to improve the cutting accuracy. When the cutting mechanism 5 is working, the third electric telescopic rod 55 moves downward to drive the fixed frame 56 to move downward so that the cutting knife 53 contacts the guide rail 6. At this time, the cutting motor 57 drives the cutting knife 53 to rotate, and the driving motor 51 drives the threaded rod 52 to rotate, thereby driving the connecting block 54 to move in the threaded rod 52, and then driving the third electric telescopic rod 55 to move, so that the cutting knife 53 cuts the guide rail 6. After cutting, the guide rail 6 can be directly taken away from the transfer platform 2.

[0024] Preferably, an upper clamping mechanism 3 symmetrical to the lower clamping mechanism 4 is provided above the lower clamping mechanism 4 .

[0025] Through the above technical solution, the lower clamping mechanism 4 is located on one side of the cutting mechanism 5, and then through the symmetrical pressing and positioning of the upper clamping mechanism 3 and the lower clamping mechanism 4, the cutting part of the guide rail 6 is fixed more stably, making the cutting more stable and improving the cutting accuracy.

[0026] Preferably, the upper positioning plate 32 threadedly mounted in the first electric telescopic rod 31 matches the size and shape of the upper surface of the guide rail 6 .

[0027] Through the above technical solution, the threaded connection between the upper positioning plate 32 and the first electric telescopic rod 31 facilitates the replacement of the upper positioning plate 32 so that it can position the upper surface of the guide rail 6 of different shapes and sizes. The upper positioning plate 32 matches the size and shape of the upper surface of the guide rail 6, which can make it fit better when in contact, thereby improving the stability of the pressed positioning.

[0028] Preferably, the lower positioning plate 42 in the second electric telescopic rod 41 matches the size and shape of the track 61 on the lower surface of the guide rail 6 .

[0029] Through the above technical solution, the threaded connection between the lower positioning plate 42 and the second electric telescopic rod 41 facilitates the replacement of the lower positioning plate 42 so that it can be inserted into the track 61 of the guide rail 6 of different shapes and sizes. The lower positioning plate 42 matches the size and shape of the track 61 on the lower surface of the guide rail 6, which can make it fit more closely when in contact, thereby improving the stability of the pressed positioning.

[0030] Preferably, two guide rods 58 are symmetrically provided on both sides of the threaded rod 52 in the support frame 11 , and the connecting block 54 in the cutting mechanism 5 is slidably connected to the two guide rods 58 .

[0031] Through the above technical solution, the provision of the two guide rods 58 ensures the stability of the movement of the connecting block 54 in the threaded rod 52, thereby ensuring the stability of the movement of the cutting mechanism 5.

[0032] Finally, it should be noted that the above implementation cases are only used to illustrate the present invention, rather than to limit the technical solutions described in the present invention; therefore, although this specification has described the present invention in detail with reference to the above-mentioned embodiments, ordinary technicians in this field should understand that the present invention can still be modified or replaced by equivalents, and all technical solutions and improvements that do not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention; technologies not described in detail in the present invention are implemented with existing technologies.
