Description

Technical Field

[0001] This utility model belongs to the field of cutting and positioning technology, specifically a positioning device for aluminum profile cutting and processing. Background Technology

[0002] Aluminum profiles are aluminum products of various shapes made primarily from aluminum and aluminum alloys through processes such as extrusion and casting. Due to their lightweight, high strength, corrosion resistance, and ease of processing, aluminum profiles are widely used in construction, transportation, electronics, machinery, and home furnishings. During processing, aluminum profiles need to be cut to the required length using cutting equipment. Traditionally, aluminum profile cutting involves a worker holding the profile in one hand and controlling the cutting equipment with the other. However, when cutting with one hand, only one side of the profile can be fixed in place. Towards the end of the cut, the unfixed side shifts, affecting the neatness of the cut and requiring recutting, repair, or grinding. Therefore, improvements are needed to address these issues. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for aluminum profile cutting and processing, comprising a convex mounting base, two limiting and fixing blocks symmetrically fixedly mounted on one side of the top of the convex mounting base, and a mounting block fixedly mounted in the middle of the other side of the top of the convex mounting base, the mounting block being located between the two limiting and fixing blocks, and two adjusting blocks symmetrically mounted on one side of the mounting block located on the two limiting and fixing blocks, the two adjusting blocks being aligned with the ends of the two limiting and fixing blocks respectively, a pressure block being fixedly mounted on the side of each adjusting block near the limiting and fixing blocks, and a clamping rubber pad being fixedly mounted on the end of each pressure block near the fixing block, and a motor for moving and adjusting the two adjusting blocks being mounted in the middle of the side of the mounting block away from the adjusting blocks.

[0004] Preferably, the mounting block has two right-angled trapezoidal mounting slots symmetrically opened on one side of the two limiting and fixing blocks. Both adjusting blocks are right-angled trapezoidal structures that match the right-angled trapezoidal mounting slots, and the two adjusting blocks are movably inserted into the two right-angled trapezoidal mounting slots. The inclined surfaces of the two adjusting blocks are provided with inverted convex inclined sliding grooves, and sliders are installed inside the two inverted convex inclined sliding grooves. The opposite sides of the right-angled trapezoidal mounting slots are provided with connecting slots, and pressing pins are movably inserted into the two connecting slots. The opposite ends of the two pressing pins are fixedly connected to the two sliders respectively.

[0005] Preferably, an inner cavity is provided between the opposite ends of the two connecting slots, located in the middle of the mounting block. A threaded shaft connected to the motor output end is rotatably mounted in the middle of the inner cavity. A U-shaped block is threadedly connected to the surface of the threaded shaft. The opposite ends of the two pressing pins extend into the inner cavity. A pressing arm is rotatably connected between the inside of the U-shaped block and the ends of the two pressing pins, so that the two pressing blocks and the clamping rubber pads thereon can be moved and adjusted synchronously, so that the two pressing blocks can be positioned and fixed by cooperating with the two limiting and fixing blocks through the clamping rubber pads thereon.

[0006] Preferably, two fixing plates are symmetrically fixedly installed at the center of the top of the convex mounting base. The two fixing plates are respectively aligned and parallel to the two limiting fixing blocks, and the two fixing plates are respectively fixedly connected to the two ends of the mounting block. Rollers are rotatably installed at equal distances between the opposite fixing plates and the limiting fixing blocks.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This positioning device has a double-sided adjustable synchronous fixing structure, which can be adjusted and fixed for aluminum profiles of different sizes, thereby ensuring the stability of both sides during aluminum profile cutting, effectively improving the neatness and quality of the aluminum profile cutting surface, and avoiding secondary processing after aluminum profile cutting. At the same time, this positioning device has a simple structural design, is convenient to use, and has stable and reliable adjustment and positioning. Its performance can meet the usage requirements of aluminum profile cutting and processing.

[0008] The aluminum profile is placed between two clamping rubber pads and two limiting blocks, while the aluminum profile is positioned on the surface of the roller. The aluminum profile can be easily moved by rotating the roller, so that the switching position of the aluminum profile is between the two limiting blocks.

[0009] Next, start the motor to rotate the threaded shaft. The rotation of the threaded shaft will cause the U-shaped block to move on its surface. The movement of the U-shaped block will squeeze the two extrusion arms and push the two extrusion pins to move toward the two adjusting blocks. The movement of the two extrusion pins will cause the slider to slide inside the inverted convex inclined slide groove and move the adjusting block out from the inside of the right-angled trapezoidal mounting groove.

[0010] The movement of the two right-angled trapezoidal mounting slots will cause the two pressure blocks and their clamping rubber pads to move toward the aluminum profile. Finally, the aluminum profile is positioned and fixed by the cooperation of the two limiting and fixing blocks, so that both sides of the aluminum profile cutting position can remain stable during the cutting process.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Depend on Figures 1 to 3 The present invention includes a convex mounting base 1. Two limiting and fixing blocks 2 are symmetrically fixedly mounted on one side of the top of the convex mounting base 1. A mounting block 3 is fixedly mounted in the middle of the other side of the top of the convex mounting base 1. The mounting block 3 is located between the two limiting and fixing blocks 2. Two adjusting blocks 4 are symmetrically mounted on one side of the mounting block 3, and the two adjusting blocks 4 are respectively aligned with the ends of the two limiting and fixing blocks 2. A pressure block 5 is fixedly mounted on the side of each adjusting block 4 near the limiting and fixing blocks 2. A clamping rubber pad 6 is fixedly mounted on the end of each pressure block 5 near the fixing block 2. A motor 7 for moving and adjusting the two adjusting blocks 4 is installed in the middle of the side of block 3 away from the adjusting block 4; two fixing plates 17 are symmetrically fixed in the middle of the top of the convex mounting base 1. The two fixing plates 17 are respectively aligned and parallel to the two limiting fixing blocks 2, and the two fixing plates 17 are respectively fixedly connected to the two ends of the mounting block 3. Rollers 18 are rotatably installed at equal distances between the opposite fixing plates 17 and the limiting fixing blocks 2, so as to facilitate the movement of the placed aluminum profile; by placing the aluminum profile on the surface of the roller 18, the aluminum profile can be easily moved by the rotation of the roller 18.

[0019] The mounting block 3 has two right-angled trapezoidal mounting slots 8 symmetrically opened on one side of the two limiting and fixing blocks 2. The two adjusting blocks 4 are both right-angled trapezoidal structures that match the right-angled trapezoidal mounting slots 8. The two adjusting blocks 4 are movably inserted into the two right-angled trapezoidal mounting slots 8. The inclined surfaces of the two adjusting blocks 4 are provided with inverted convex inclined sliding grooves 9. The sliding blocks 10 are installed inside the two inverted convex inclined sliding grooves 9. The opposite sides of the right-angled trapezoidal mounting slots 8 are provided with connecting slots 11. The two connecting slots 11 are movably inserted with pressing pins 13. The opposite ends of the two pressing pins 13 are fixedly connected to the two sliding blocks 10 respectively.

[0020] An inner cavity 12 located in the middle of the mounting block 3 is opened between the opposite ends of the two connecting slots 11. A threaded shaft 14 connected to the output end of the motor 7 is rotatably installed in the middle of the inner cavity 12. A U-shaped block 15 is threadedly connected to the surface of the threaded shaft 14. The opposite ends of the two extrusion pins 13 extend into the interior of the inner cavity 12. An extrusion arm 16 is rotatably connected between the interior of the U-shaped block 15 and the ends of the two extrusion pins 13, so that the two pressure blocks 5 and the clamping rubber pads 6 on them can be moved and adjusted synchronously, so that the two pressure blocks 5 can be positioned and fixed by cooperating with the two limiting and fixing blocks 2 through the clamping rubber pads 6 on them.

[0021] Specifically, the aluminum profile is placed between two clamping rubber pads 6 and two limiting fixing blocks 2, so that the switching position of the aluminum profile is between the two limiting fixing blocks 2. Then, the motor 7 is started to rotate the threaded shaft 14. The rotation of the threaded shaft 14 will cause the U-shaped block 15 to move on its surface. The movement of the U-shaped block 15 will squeeze the two extrusion arms 16 and push the two extrusion pins 13 to move towards the two adjusting blocks 4. The movement of the two extrusion pins 13 will cause the slider 10 to slide inside the inverted convex inclined slide groove 9 and cause the adjusting block 4 to move out from the inside of the right-angled trapezoidal mounting groove 8.

[0022] The movement of the two right-angled trapezoidal mounting slots 8 will cause the two pressure blocks 5 and the clamping rubber pads 6 on them to move toward the aluminum profile. Finally, the aluminum profile is positioned and fixed by the cooperation of the two limiting and fixing blocks 2, so that both sides of the aluminum profile cutting position can remain stable during the cutting process.

[0023] This positioning device features a dual-sided adjustable synchronous fixing structure, which can be adjusted and fixed for aluminum profiles of different sizes, thereby ensuring the stability of both sides during aluminum profile cutting. This effectively improves the neatness and quality of the cut surface of the aluminum profile and avoids secondary processing after aluminum profile cutting.

Its performance can meet the needs of aluminum profile cutting and processing.
