Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum frame processing, and particularly relates to an angle deflection tracking assembly of an aluminum frame chamfering and polishing machine. Background Technique

[0002] At present, the frames of some doors and windows are formed by stamping and folding the edges after cutting the aluminum alloy plates, and then assembling the corner codes. After the aluminum alloy materials are cut, the cutting parts are often not flat enough or have burrs, which need to be polished smoothly. Otherwise, it will affect the subsequent corner assembly. After the corner assembly is completed, the aluminum alloy materials and the sharp points of the right angles also need to be polished to make the appearance of the aluminum alloy door and window frames flat and meet the installation standards while maintaining beauty. The existing technical means mostly use hand-held grinders or manual sandpapers for grinding. Grinding with a hand-held grinder requires fixing the aluminum alloy door and window frames, generally requiring the cooperation of multiple people, and there is no protection device, which is dangerous and the grinding is not standard.

[0003] For this reason, a grinding and polishing device for the production of aluminum alloy windows with the publication number of "CN218556646U" includes a workbench, a grinding disc, a polishing plate and a motor. A baffle is fixedly connected to the workbench. A circular through hole is opened on the workbench on one side of the baffle, and a square hole is opened on the workbench on the other side. First slide rails are fixedly connected to both sides of the square hole of the workbench, and a polishing plate is slidably connected to the first slide rails. A second connecting rod is fixedly connected below the workbench, and a base is fixedly connected below the second connecting rod. A grinding disc is arranged in the circular hole of the workbench. A first rotating shaft is fixedly connected below the grinding disc, and the first rotating shaft passes through the circular through hole on the base and is fixedly connected to the rotating shaft of the first motor. By installing clamping plates on both sides above the grinding disc, it not only restricts the displacement of the grinding material but also plays a protective role. The pressing plate is arranged on the polishing plate, which is more convenient when replacing the sandpaper. Both grinding and polishing are driven by the motor, and the working efficiency is high.

[0004] However, for the above-mentioned grinding and polishing device for the production of aluminum alloy windows, although clamping plates are installed on both sides above the grinding disc, which not only restricts the displacement of the grinding material but also plays a protective role, and the pressing plate is arranged on the polishing plate, which is more convenient when replacing the sandpaper, there are still the following obvious defects in the use process: when polishing the corners of the aluminum frame, due to the lack of corresponding tracking and limiting of the polishing angle of the aluminum frame corners, it is easy to have problems of inaccurate polishing angle and error when polishing the corners of the aluminum frame. Summary of the Invention

Locking fixing blocks are locked at both ends of the deflection shaft. The self-lubricating copper sleeve is fixed on both sides of the movable angle-tracking stopper, which can make the movable angle-tracking stopper track and slide-adjust according to the angle of the aluminum frame corner-throwing, avoiding errors in corner-throwing.

[0011] Preferably, at the bottom end of the piston rod of the cylinder part, there is a vertical pressing plate with one end in a triangular shape and extending into the hollowed-out surface of the movable angle-tracking stopper, which is used for downward positioning of the aluminum frame in the aluminum profile cavity, so as to keep it stable and firm during corner-throwing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model provides a technical solution: an angle deflection tracking assembly for an aluminum frame chamfer polishing machine, comprising:

[0023] A chamfering table surface 1, one end of the surface of the chamfering table surface 1 is formed with an aluminum material cavity 3 for chamfering the angle positioning of the aluminum frame workpiece and having a right-angle structure through a positioning angle bar 2. A strip-shaped limiting plate extending upward for limiting the side end of the aluminum frame is provided on the side of the aluminum material cavity 3, and one end of the strip-shaped limiting plate extends to a position close to the chamfering groove 4 and is located in the hollow cavity of the movable angle tracking block 5, strengthening the positioning effect during the chamfering of the aluminum frame and reducing the deviation caused by shaking. A chamfering groove 4 with a V-shaped structure is opened at the top corner end of the aluminum material cavity 3, and the corner of the chamfering groove 4 corresponds to the corner of the aluminum material cavity 3, facilitating the polishing wheel to polish the angle at the corner of the aluminum frame. A movable angle tracking block 5 with a hollowed-out surface slides on the corresponding upper end of the chamfering groove 4. The movable angle tracking block 5 can slide during the chamfering of the aluminum frame to perform a following movement during angle polishing, avoiding errors in the polished angle and eliminating the need for manual position adjustment of the angle of the chamfering flap 10.

[0024] On one side of the center position of one surface of the cross beam in the fixed bracket 6, there is a push-pull electromagnetic block 7 for angle deflection tracking of the aluminum frame corner throw. When an abnormal situation of the aluminum frame corner throw is detected, the circuit can be quickly disconnected to stop the operation of the corner throw machine. And by controlling the on-off of the current, the start and stop of the corner throw machine can be conveniently realized, so as to control the start and end of the aluminum frame corner throw processing process. At the same time, the push-pull electromagnetic block 7 can accurately control the angle of the aluminum frame corner throw by the corner throw machine. When current is passed through the coil, the coil generates a magnetic field, making the iron core become a temporary magnet. This magnet will attract another iron block (usually the iron block above or near the iron core), thus attracting them together. This attraction is the basis for the operation of the electromagnetic block. And when current passes through the coil, the iron core is attracted by the magnetic force and will move towards the coil direction, so that the moving part of the push-pull electromagnetic block 7 (usually the moving arm or push rod connected to the iron core) also moves together. This movement enables the push-pull electromagnetic block 7 to achieve the push-pull function, and then can accurately control the start and stop of the corner throw machine. And on one side of the push-pull electromagnetic block 7 and in the middle of one surface of the cross beam of the fixed bracket 6, there is a cylinder part 8 for downward pressing and positioning of the aluminum frame corner throw. The cylinder part 8 is provided with double piston rods and can make the vertical pressing plate 16 move horizontally downward to press and position the aluminum frame.

[0025] On one surface of the movable angle tracking stop block 5, there is a stop piece fixing plate 9 in the shape of an eight-character. There is a corner throw angle spacing left between the stop piece fixing plates 9. And through holes are provided on the stop piece fixing plates 9 for adjusting the size of the gap between the corner throw stop pieces 10. The inner side surface of the stop piece fixing plate 9 is fixed with corner throw stop pieces 10 for controlling the size adjustment of the aluminum frame corner throw. The corner throw stop pieces 10 are fixed on the inner side of the stop piece fixing plate 9 by adjusting the locking bolts passing through the stop piece adjustment screw holes, which is beneficial for positioning the corner of the aluminum frame that needs to be corner thrown. On one side of the movable angle tracking stop block 5 and at the vertical bottom end of the push-pull electromagnetic block 7, there is an outward extending connecting piece 11, which is beneficial for the movable penetration and fixation of the electromagnetic pull rod in the push-pull electromagnetic block 7.

[0026] On both sides of the 4-port of the chamfering groove, there are offset pivot seats 12. Between the inner sides of the offset pivot seats 12, there is a self-lubricating copper sleeve 13, which enables the movable angle tracking block 5 to deflect and slide on the offset pivot 14 through the self-lubricating copper sleeve 13 to adjust the polishing angle. The self-lubricating copper sleeve 13 is inserted into and fixed with an offset pivot 14 at the outer end of the offset pivot seat 12, which can play a role in adjusting the angle offset during the process of the movable angle tracking block 5 pressing tightly against the aluminum frame corner. It can automatically adjust the polishing angle according to the angle of the aluminum frame corner, making the angle thrown by the aluminum frame corner more accurate, without generating chamfering errors. The two ends of the offset pivot 14 are locked with locking and fixing blocks 15, which are used to limit the locking of the two ends of the offset pivot 14. The self-lubricating copper sleeve 13 is fixed on both sides of the movable angle tracking block 5, facilitating the effect of driving the movable angle tracking block 5 to slide and automatically adjust the tracking polishing angle, without the need for manual angle adjustment. The bottom end of the piston rod of the cylinder part 8 is fixed with a vertical pressure plate 16 with one end in a triangular shape and extending into the hollow side of the movable angle tracking block 5, which can make the triangular end of the vertical pressure plate 16 align and press against the aluminum frame corner, preventing the problem of excessive chamfering of the aluminum frame corner by the chamfering machine and further improving the accuracy of the aluminum frame chamfering.

[0027] On the crossbeam of the fixed bracket 6, there is an installation frame 17 fixed through a sheet plate. On the outer side of the installation frame 17, there is a fixed sheet plate, and the fixed sheet plate is fixed on one side of the middle part of the crossbeam of the fixed bracket 6 by screws. The push-pull electromagnet 7 is fixed inside the installation frame 17, and one end of the electromagnetic pull rod in the push-pull electromagnet 7 passes through the upper end of the installation frame 17 and is limited and sleeved with a return spring 18, which enables the electromagnetic pull rod to expand and contract and reset after passing current in the push-pull electromagnet 7, and plays a role in controlling the on-off start-stop, and is used to control the start-stop of the equipment switch, facilitating further improvement of the chamfering accuracy. And the bottom end of the electromagnetic pull rod movably passes through the connecting piece 11, and an active spring 19 is sleeved on the electromagnetic pull rod on the inner side and the upper side of the connecting piece 11, which enables the electromagnetic pull rod to move up and down actively. By controlling the on-off of the current, using the electromagnetic attraction and release actions to achieve the push-pull action, thereby controlling the start-stop or push-pull function of the equipment. Inside the aluminum material fixed cavity 3 and at the center position of the chamfering table 1, there is a horizontal pressure plate 20 slidably arranged for pressing tightly against the aluminum frame angle, which can strengthen the accurate positioning of the aluminum frame during chamfering.

[0028] Specifically, during use, first place the aluminum frame in the aluminum material fixed cavity 3, making the polished corners of the aluminum frame tightly press against the inner corners of the aluminum material fixed cavity 3. Then, use the sliding top plate to tightly fix the inner corners of the aluminum frame. Ensure that the outer corners of the aluminum frame are at the upper end of the inner cavity of the corner polishing groove 4. Fix the corner polishing piece 10 on the inner side of the movable angle tracking stop block 5 through the stop piece fixing plate 9 designed in an eight-character structure using screws, and adjust the gap size between the corner polishing pieces 10. Then, the outer corner of the aluminum frame that needs corner polishing can be placed in the gap between the corner polishing pieces 10, allowing the corner part that needs to be polished to protrude outside the gap. Connect the push-pull electromagnet block 7 to the corner polishing machine for power-on and start / stop control. At this time, the cylinder part 8 pushes the vertical pressure plate 16 downward, making the triangular end of it accurately press down on the edge of the aluminum frame corner for alignment. Subsequently, the polishing wheel in the corner polishing machine approaches the corner that needs to be polished and protrudes from the gap between the corner polishing pieces 10 for corner polishing work. At the same time, during the angle polishing of the polishing wheel, the movable angle tracking stop block 5 can automatically track and adjust the angle through the self-lubricating copper sleeve 13, and then realize the angle deflection tracking adjustment of the corner polishing piece 10 using the deflection shaft 14. Thus, there is no need for personnel to manually adjust the angle of the corner polishing piece 10, which can make the polishing angle of the aluminum frame corner more accurate and avoid the problem of errors in aluminum material corner polishing, further improving the quality and accuracy of aluminum frame corner polishing.
