Description

Technical Field

[0001] This utility model relates to the field of door and window processing technology, specifically a chamfering device for system door and window processing. Background Technology

[0002] Chamfering is an important step in the manufacturing process of aluminum alloy doors and windows. It mainly involves removing the sharp edges of the aluminum alloy doors and windows to make the edges smooth, thereby improving the aesthetics and safety of the doors and windows.

[0003] According to a public notice (No. CN120480714A) regarding a chamfering device for processing system doors and windows, the above application includes a base plate, a worktable fixedly connected to the top of the base plate, a control plate fixedly connected to the outer wall of the worktable, and a chamfering mechanism movably connected to the bottom of the worktable. An electric telescopic rod rotates a sleeve plate to make the suction pipe move in a circular motion, and a chamfering motor drives a rotating chamfering wheel to rotate, so that the chamfering wheel can grind and chamfer the frame of the door and window.

[0004] However, in actual use, the above-mentioned chamfering device can only chamfer one side of the edge at a time. Each workpiece needs to be positioned two or more times, that is, chamfer one side first, and then flip or rotate to chamfer the other side. The working time and processing cycle are doubled, and the production capacity is significantly reduced. The secondary clamping or flipping will bring fixture positioning errors, resulting in inconsistent chamfering on both sides, which affects the assembly gap and appearance. In view of this, we propose a chamfering device for system door and window processing. Utility Model Content

[0005] The purpose of this utility model is to provide a chamfering device for system door and window processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a chamfering device for processing system doors and windows, comprising a body, a cylinder fixedly connected to the top end face of the body, a mounting plate fixedly connected to the output end of the cylinder, and a chamfering assembly provided on the bottom end face of the mounting plate, the chamfering assembly comprising:

[0007] A servo motor, the output end of which is fixedly connected to a bidirectional screw, the side wall of which is threadedly connected to a frame, and the side wall of which is fixedly connected to an adjustment bracket;

[0008] The mounting frame has a chamfering motor fixedly connected to its end face, a chamfering wheel fixedly connected to the output end of the chamfering motor, a limit rod slidably connected to the inner wall of the mounting frame, an elastic telescopic rod fixedly connected to the inner wall of the mounting frame, and an abutment plate fixedly connected to the end face of the elastic telescopic rod.

[0009] A dust collection hood, wherein an air suction pipe is fixedly connected to the side wall of the dust collection hood;

[0010] A vertical frame is slidably connected to a sliding frame and a horizontal bar, and a clamping frame is fixedly connected to the end face of the vertical frame.

[0011] Preferably, a vertical rod is fixedly connected to the inner bottom surface of the machine body, and the vertical rod is slidably connected to the mounting plate to maintain the stability of the mounting plate's movement.

[0012] Preferably, the servo motor is fixedly connected to the side wall of the mounting plate, the frame is slidably connected to the inner top surface of the mounting plate, the side wall of the adjustment frame is provided with a through arc-shaped sliding groove, and a slot is provided at the edge of the sliding groove.

[0013] Preferably, the mounting bracket is slidably connected to the frame body, the limiting rod is slidably connected to the arc-shaped sliding groove, the end face of the limiting rod is fixedly connected to a handle, and the elastic telescopic rod includes a sleeve fixedly connected to the inner wall of the mounting bracket. The sleeve is sleeved with the movable rod, and a spring is provided inside the sleeve. One end of the spring abuts against the inner bottom surface of the sleeve, and the other end of the spring abuts against the movable rod.

[0014] Preferably, the dust hood is fixedly connected to the outer wall of the chamfered motor, and the suction pipe is fixedly connected to the air inlet of the external dust collection device. The suction pipe collects metal debris inside the dust hood.

[0015] Preferably, the sliding frame is slidably connected to the mounting plate, and the crossbar is fixedly connected to the side wall of the frame. The lateral movement of the frame and the crossbar causes the sliding frame to move laterally. The contact position between the crossbar and the sliding frame is a plane, so that the sliding frame always remains vertical.

[0016] Preferably, the inner top surface of the clamping frame is rotatably connected to rollers, and the number of rollers is set in several groups, with the several groups of rollers being equally spaced on the inner top surface of the clamping frame.

[0017] Compared with the prior art, this utility model provides a chamfering device for system door and window processing, which has the following beneficial effects:

[0018] 1. This system's chamfering device for door and window processing uses a chamfering assembly, two sets of chamfering motors, and chamfering wheels moving in opposite directions. The chamfering wheels contact the edges and corners of the aluminum alloy doors and windows, simultaneously grinding and chamfering both sides. A limiting rod engages with different slots, allowing for adjustments to the chamfering angle of the chamfering wheels to meet various production needs. A clamping frame holds the aluminum alloy doors and windows, forming a guide rail for the profile. A single adjustment completes the adjustment of the chamfering wheels and the guidance of the profile, eliminating the need for separate chamfering wheel and guide rail devices, thus simplifying the workflow.

[0019] 2. The chamfering device for door and window processing in this system uses rollers to ensure that when the workpiece contacts the clamping frame, it is not a surface friction but a rolling friction of the rollers. The rolling friction coefficient is much smaller than that of sliding friction. The workpiece can be easily pushed along the guide rail even when it is clamped, avoiding jamming and reducing friction damage, thus preventing scratches on the profile surface.

[0027] like Figures 1-6 As shown, this utility model provides a technical solution: a chamfering device for processing system doors and windows, including a body 1, a cylinder 2 fixedly connected to the top end face of the body 1, an installation plate 3 fixedly connected to the output end of the cylinder 2, and a chamfering component 4 provided on the bottom end face of the installation plate 3. The chamfering component 4 includes a servo motor 401, a bidirectional screw 402, a frame 403, an adjusting frame 404, an installation frame 405, a chamfering motor 406, a chamfering wheel 407, a limiting rod 408, an elastic telescopic rod 409, an abutment plate 410, a dust suction hood 411, an air suction pipe 412, a vertical frame 413, a sliding frame 414, a horizontal bar 415, and a clamping frame 416.

[0028] In one embodiment of this utility model, a servo motor 401 is fixedly connected to the side wall of the mounting plate 3. A bidirectional screw 402 is fixedly connected to the output end of the servo motor 401. A frame 403 is threadedly connected to the side wall of the bidirectional screw 402. An adjustment frame 404 is fixedly connected to the side wall of the frame 403. The frame 403 is slidably connected to the inner top surface of the mounting plate 3. A through arc-shaped groove is provided on the side wall of the adjustment frame 404. A slot is provided at the edge of the groove.

[0029] Mounting bracket 405 is slidably connected to frame 403. A chamfering motor 406 is fixedly connected to the end face of mounting bracket 405. A chamfering wheel 407 is fixedly connected to the output end of chamfering motor 406. A limit rod 408 is slidably connected to the inner wall of mounting bracket 405. An elastic telescopic rod 409 is fixedly connected to the inner wall of mounting bracket 405. An abutment plate 410 is fixedly connected to the end face of elastic telescopic rod 409. The limit rod 408 is slidably connected to arc-shaped groove. A handle 6 is fixedly connected to the end face of limit rod 408. Elastic telescopic rod 409 includes a sleeve fixedly connected to the inner wall of mounting bracket 405. The sleeve is sleeved with a movable rod. A spring is provided inside the sleeve. One end of the spring abuts against the inner bottom surface of the sleeve, and the other end of the spring abuts against the movable rod.

[0030] The dust hood 411 is fixedly connected to the outer wall of the chamfering motor 406. The side wall of the dust hood 411 is fixedly connected to the suction pipe 412. The suction pipe 412 is fixedly connected to the air inlet of the external dust collection device. The dust hood 411 shields the metal shavings generated during grinding to prevent them from flying. The suction pipe 412 collects the metal shavings inside the dust hood 411.

[0031] The vertical frame 413 is slidably connected to the sliding frame 414, which is slidably connected to the mounting plate 3. The vertical frame 413 is slidably connected to the horizontal bar 415, which is fixedly connected to the side wall of the frame 403. The horizontal movement of the frame 403 and the horizontal bar 415 causes the sliding frame 414 to move horizontally. The contact position between the horizontal bar 415 and the sliding frame 414 is a plane, so that the sliding frame 414 always remains vertical. The end face of the vertical frame 413 is fixedly connected to the clamping frame 416.

[0032] A vertical rod 5 is fixedly connected to the bottom surface of the inner part of the body 1. The vertical rod 5 is slidably connected to the mounting plate 3 to maintain the stability of the movement of the mounting plate 3.

[0033] Cylinder 2 controls the lowering of mounting plate 3 and chamfering assembly 4, allowing chamfering wheel 407 to contact the edges and corners of aluminum alloy doors and windows. Servo motor 401 drives bidirectional screw 402 to rotate, further driving two sets of chamfering motors 406 and chamfering wheel 407 to move towards each other, so that chamfering wheel 407 contacts the edges and corners of aluminum alloy doors and windows, and simultaneously grinds and chamfers both sides of aluminum alloy doors and windows, saving a lot of loading, unloading and turning time. The two chamfering wheels 407 are controlled by the same bidirectional screw 402, and the movement is symmetrical, ensuring that the chamfering depth, angle and width on both sides are consistent, avoiding positioning errors introduced by manual turning or multiple processes, and improving the fit and aesthetics of door and window assembly.

[0034] Push the handle 6 downwards to disengage the limit rod 408 from the slot. Then slide the limit rod 408 to slide within the arc-shaped groove. Through the elasticity of the elastic telescopic rod 409, the limit rod 408 engages with different slots, thereby changing the chamfer angle of the chamfering wheel 407, such as 30 degrees, 45 degrees, 90 degrees, etc. The chamfer angle is adjustable to adapt to various production needs. At the same time, the slot position is fixed and the corresponding angle is preset, so it can automatically reach the correct position each time it is switched, ensuring that the chamfer angle is consistent.

[0035] While the bidirectional screw 402 drives the frame 403 to move laterally, the frame 403 drives the vertical frame 413 to move laterally through the crossbar 415, further enabling the clamping frame 416 to clamp the aluminum alloy door and window. The clamping frame 416 forms the profile's push guide rail. After one adjustment, the adjustment of the chamfering wheel 407 and the guide rail device can be completed. There is no need to set the chamfering wheel 407 and the guide rail device separately, ensuring that the workpiece moves along the predetermined trajectory during the chamfering process. The workpiece is not easy to shake or deviate. The chamfering wheel 407 has more uniform contact with the edge corner of the profile, and the processing dimensions and angles are more stable.

[0036] In addition, rollers 7 are rotatably connected to the inner top surface of the clamping frame 416. Several sets of rollers 7 are arranged at equal intervals on the inner top surface of the clamping frame 416. When the workpiece contacts the clamping frame 416, it is not surface friction, but rolling friction of the rollers 7. The rolling friction coefficient is much smaller than that of sliding friction. The workpiece can be easily pushed along the guide rail in the clamped state, avoiding jamming, reducing friction damage and preventing scratches on the profile surface.

[0037] In this invention, during use, two sets of chamfering motors 406 and chamfering wheels 407 move towards each other, causing the chamfering wheels 407 to contact the edges and corners of the aluminum alloy doors and windows. Simultaneously, the two sides of the aluminum alloy doors and windows are ground and chamfered. The limiting rod 408 engages with different slots to change the chamfering angle of the chamfering wheels 407, adapting to various production needs. The clamping frame 416 clamps the aluminum alloy doors and windows, forming a guide rail for the profile. After one adjustment, the adjustment of the chamfering wheels 407 and the guidance of the profile can be completed, eliminating the need to separately set up the chamfering wheels 407 and the guide rail device, thus simplifying the workflow.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
