Description

Technical Field

[0001] The present application relates to the technical field of aluminum alloy door and window processing, and in particular to a clamping and fixing device for aluminum alloy door and window processing. Background Art

[0002] Aluminum alloy doors and windows are an important part of the building's outer protective structure, with lighting, ventilation, rain protection and anti-theft functions. At the same time, they must also meet the needs of the use environment, architectural style, and decoration. The performance of aluminum alloy doors and windows is inseparable from the good processing technology in its production and processing. When assembling aluminum alloy profiles used to make frames, clamping and fixing devices are required for positioning;

[0003] For example, a clamping and fixing device for aluminum alloy door and window processing with announcement number CN218518199U adopts the cooperation among a motor, a threaded rod, a lifting plate, bolts, nuts and a movable plate. By starting the motor, the threaded rod is rotated, and then the lifting range is limited by the limit of the movable groove and the limit rod. At the same time, the bolts and nuts cooperate with each other to ensure that the clamping adjustment is carried out according to the aluminum alloy doors and windows of different thicknesses, so that the movable plate clamps and fixes the surface of the doors and windows;

[0004] The device fixes the workpieces by relative movement between the fixed plate and the movable plate. When two workpieces need to be butt-jointed at a 45° angle, it is not convenient to flexibly adjust the angle between the fixed plate and the movable plate, resulting in low workpiece alignment accuracy, affecting product quality.

[0005] Therefore, the present application provides a clamping and fixing device for processing aluminum alloy doors and windows to meet the needs. Utility Model Content

Detailed implementation manners

[0027] As Figure 1 , Figure 2 shown, a clamping and fixing device for processing aluminum alloy doors and windows provided by an embodiment of this application includes the first fixing seat 1 and the second fixing seat 2. The first fixing seat 1 and the second fixing seat 2 are hinged through the hinge 3. Oblique cutouts are provided on the adjacent sides of the first fixing seat 1 and the second fixing seat 2. A positioning seat 101 is fixedly connected to the top of the first fixing seat 1, and a positioning hole is provided on the side wall of the positioning seat 101. A connecting seat 201 is fixedly connected to the top of the second fixing seat 2, a positioning rod 202 is inserted into the connecting seat 201, and a limiting piece 301 is fixedly connected to the end of the hinge 3;

[0028] The first fixing seat 1 and the second fixing seat 2 are connected through the hinge 3. The first fixing seat 1 and the second fixing seat 2 can only rotate relative to each other under the guidance of the hinge 3, and the rotation angle range is 90° - 270°. By respectively fitting the oblique cutouts on the first fixing seat 1 and the second fixing seat 2, the relative angle between the first fixing seat 1 and the second fixing seat 2 is 90 degrees, so that two workpieces can be quickly butted to the 90° alignment state. By inserting the positioning rod 202 into the positioning hole on the side wall of the positioning seat 101, the angle between the first fixing seat 1 and the second fixing seat 2 is stably maintained;

[0029] When the angle between the first fixing seat 1 and the second fixing seat 2 is adjusted to 180°, the positioning rod 202 can still be inserted into the through hole on the side wall of the positioning seat 101. Similarly, the first fixing seat 1 and the second fixing seat 2 can also be in a 270° angle;

[0030] The limiting piece 301 provided at the end of the hinge 3 can further limit the first fixing seat 1 and the second fixing seat 2 to make them in the same horizontal plane, ensuring that the two workpieces are in the same plane during assembly and improving the assembly accuracy.

[0031] In this embodiment, asFigures 2 - 5 As shown in the figure: A first threaded rod 102 penetrates through the center of the top of the first fixed seat 1, and a first clamping plate 103 is rotatably connected to the bottom of the first threaded rod 102;

[0032] A second threaded rod 203 penetrates through the center of the top of the second fixed seat 2, and a second clamping plate 204 is rotatably connected to the bottom of the second threaded rod 203;

[0033] A notch is provided on one side of the first fixed seat 1, and the first clamping plate 103 is arranged in the notch and can slide up and down. By rotating the first threaded rod 102, the position of the first clamping plate 103 can be adjusted to clamp and fix the workpiece;

[0034] Similarly, the second threaded rod 203 is used to adjust the position of the second clamping plate 204 inside the second fixed seat 2 to achieve clamping.

[0035] Through holes with the same diameter as the positioning rod 202 are provided on the front, rear, and right side walls of the positioning seat 101;

[0036] Positioning holes are provided on the front side, right side wall, and rear side of the positioning seat 101, corresponding to the 90°, 180°, and 270° angles of the positioning rod 202 relative to the positioning seat 101 respectively.

[0037] The oblique cutouts on the sides of the first fixed seat 1 and the second fixed seat 2 are both 45°;

[0038] The first fixed seat 1 and the second fixed seat 2 are positioned by the fitting of the oblique cutouts, which is convenient to keep a 90° angle between the first fixed seat 1 and the second fixed seat 2. When assembling the right-angled corners of aluminum alloy doors and windows, the workpieces can be respectively inserted into the notches inside the first fixed seat 1 and the second fixed seat 2, and the two workpieces can be aligned at a 45-degree angle through the angle, so as to keep the workpieces in a 90° angle position, with high assembly accuracy.

[0039] External threads are provided on the surface of the positioning rod 202, and the through hole on the outer side wall of the connecting seat 201 is an internal thread hole;

[0040] The positioning rod 202 and the connecting seat 201 are threadedly connected, and are not easily separated. Moreover, the positioning rod 202 is always limited by the thread, and the position of the positioning rod 202 is stable and accurate, so as to quickly align the positioning rod 202 with the positioning seat 101.

[0041] The axial length of the hinge 3 is the same as the height of the first fixed seat 1;

[0042] The limiting piece 301 at the end of the hinge 3 can simultaneously fit the first fixed seat 1 and the second fixed seat 2, maintaining a good limiting effect.

[0043] The limiting piece 301 is circular, the diameter of the limiting piece 301 is 1.5 times the diameter of the hinge, the number of the limiting pieces 301 is two, and the two limiting pieces 301 are respectively located at both ends of the hinge 3;

[0044] The limiting piece 301 is slidably connected between the first fixed seat 1 and the second fixed seat 2, and limits the position between the first fixed seat 1 and the second fixed seat 2 from the upper and lower sides, so as to keep the first fixed seat 1 and the second fixed seat 2 in the same horizontal plane.
