Description

[0001] This utility model relates to the field of profile processing technology, and in particular to a profile corner cutting mechanism. Background Technology

[0002] Door and window frames are assembled from various profiles. During the manufacturing process, after the profiles are cut to the specified length, the ends of the profiles need to be beveled. This allows the end faces of the two profiles to fit together at a predetermined angle. Existing door and window beveling machines can generally only cut 45° bevels. These machines cannot be adjusted to different angles to suit various needs, making them inflexible in use. Utility Model Content

[0006] Furthermore, the number of the corner cutting machine components is two; the corner cutting machine components are arranged sequentially along the conveying direction of the longitudinal straight module.

[0007] Furthermore, a protective device is provided on the front surface of the main frame; the protective device includes a fixed baffle fixed to the main frame and a lifting baffle slidably connected to the fixed baffle; a lifting assembly is provided between the lifting baffle and the fixed baffle.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figures 1 to 6 As shown, the corner-cutting mechanism of this utility model includes a main frame 5; a corner-cutting machine assembly 1 is provided on the main frame 5; the corner-cutting machine assembly 1 includes a corner-cutting motor 103, a rotating mechanism 104 for driving the corner-cutting motor 103 to rotate on a horizontal plane, a lifting linear module 105 for driving the rotating mechanism 104 to perform lifting and lowering movements, a transverse linear module 106 for driving the lifting linear module 105 to move laterally, and a longitudinal linear module 101 for driving the transverse linear module 106 to move longitudinally; a corner-cutting saw disc 102 is fixed to the output end of the corner-cutting motor 103.

[0023] A rack and guide rail are fixed on the main frame 5. The longitudinal linear module 101 mainly includes a motor, gears, and an outer housing for fixing the motor. The outer housing is slidably connected to the guide rail of the main frame 5. The gears mesh with the rack. The motor drives the gears to rotate, so that the longitudinal linear module 101 and the transverse linear module 106 perform longitudinal linear motion on the main frame 5. The transverse linear module 106 and the lifting linear module 105 are essentially no different from the prior art. The two ends of the transverse linear module 106 are respectively connected to the longitudinal linear module 101 and the lifting linear module 105. The two ends of the lifting linear module 105 are respectively connected to the transverse linear module 106 and the rotating mechanism 104. The rotating mechanism 104 is essentially no different from the prior art and can drive the chamfered motor 103 to rotate 360 ​​degrees on the horizontal plane.

[0024] The longitudinal linear module 101, the transverse linear module 106, and the lifting linear module 105 work together to move the corner saw 102 in the X, Y, and Z axis directions, thereby controlling the corner position of the corner saw 102 and cutting the profile. After the rotating mechanism 104 drives the corner saw motor 103 to rotate, the sawing angle of the corner saw 102 is adjusted so that the corner saw 102 can cut different angles.

[0025] In a preferred embodiment of this utility model, the number of the corner cutting machine components 1 is two; the corner cutting machine components 1 are arranged sequentially along the conveying direction of the longitudinal straight module 101;

[0026] Two corner cutting machine components 1 can simultaneously cut the two ends of the profile at any angle, improving corner cutting efficiency.

[0027] In a preferred embodiment of the present invention, a protective device 2 is provided on the front surface of the main frame 5; the protective device 2 includes a fixed baffle 203 fixed on the main frame 5 and a lifting baffle 202 slidably connected to the fixed baffle 203; a lifting assembly 201 is provided between the lifting baffle 202 and the fixed baffle 203.

[0028] Under normal operating conditions, the lifting baffle 202 is raised by the lifting assembly 201 to a height higher than the profile to block the chips flying out during profile cutting; when the corner cutting machine assembly 1 needs maintenance, the lifting assembly 201 lowers the lifting baffle 202, so that the lifting baffle 202 and the fixed baffle 203 are folded together, exposing the corner cutting machine assembly 1 for easy maintenance.

[0029] In a preferred embodiment of this utility model, the lifting assembly 201 includes a lifting guide rail 20101 fixed on a fixed baffle 203, a lifting slider 20103 slidably connected to the lifting guide rail 20101, and a long cylinder 20104 with one end fixed to the fixed baffle 203; a connecting strip 20102 is fixed to the other end of the long cylinder 20104; both the connecting strip 20102 and the lifting slider 20103 are fixed to the lifting baffle 202; the long cylinder 20104 pushes the connecting strip 20102, causing the lifting baffle 202 to slide up and down along the lifting guide rail 20101.

[0030] In a preferred embodiment of this utility model, a T-slot 20201 is provided on the end face of the lifting baffle 202; a strip groove 20102 is provided on the connecting strip 20102; the T-slot 20201 is composed of a horizontal groove 2020101 and an open groove 2020102; one end of the open groove 2020102 extends to the top surface of the lifting baffle 202; the other end of the open groove 2020102 is connected to the horizontal groove 2020101; the lifting baffle 202 and the connecting strip 20102 are connected and fixed by bolts and nuts; the head of the bolt is inserted into the interior of the horizontal groove 2020101; the bolt body passes through the open groove 2020102 and the strip groove 2010201 in sequence; and is then threadedly connected to the nut.

[0031] The width of the opening groove 2020102 is smaller than the diameter of the bolt head; the bolt and the lifting baffle 202 are snapped into the horizontal groove 2020101 by a snap-fit ​​method, which facilitates the assembly of the bolt and the lifting baffle 202; when connecting the lifting baffle 202 and the connecting strip 20102, first pass the bolt through the strip groove 2010201 from top to top, then slide the bolt along the direction of the opening groove 2020102, and the head of the bolt is inserted horizontally into the horizontal groove 2020101, while the bolt body is embedded in the opening groove 2020102. After adjusting the position of the bolt in the T-slot 20201 and the strip groove 2010201, the nut is locked. The assembly of the lifting baffle 202 and the connecting strip 20102 is simple and the disassembly and assembly efficiency is high.

[0032] In a preferred embodiment of this utility model, a long straight guide rail 204 is provided on the front surface of the fixed baffle 203; a horizontal slider is slidably connected to the long straight guide rail 204; an operating table 3 is fixed on the horizontal slider; the operating table 3 is an operating panel; the operating table 3 can slide on the long straight guide rail 204 to adjust the position of the operating table 3 on the fixed baffle 203.

[0033] In a preferred embodiment of this utility model, at least two clamping and conveying assemblies 4 are provided on the main frame 5; the clamping and conveying assembly 4 includes a clamping module and a longitudinal conveying module for driving the clamping module to move longitudinally.

[0034] The clamping module is not fundamentally different from existing technology, so it will not be described in detail. The clamping module can perform two actions: clamping and fixing the profile or loosening the clamping of the profile. The longitudinal conveying module is not fundamentally different from existing technology, so it will not be described in detail. The longitudinal conveying module is used to drive the clamping module to move and realize the conveying of the profile, automatically conveying the profile to the bottom of the corner cutting machine assembly 1.

[0035] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
