Description

Technical Field

[0001] This utility model relates to the field of cutting and fixing devices, and in particular to a cutting and fixing device for extruded aluminum tubes. Background Technology

[0002] Extruded aluminum tubes are produced by placing aluminum billets into a mold cavity or extrusion cylinder and then applying strong pressure to force them through the mold orifice, thereby obtaining aluminum tubes with the desired cross-sectional shape, size and mechanical properties. This process is carried out under high temperature and high pressure, and can produce aluminum tubes with diverse specifications and shapes. After the extruded aluminum tubes are produced, they need to be cut, and a cutting and fixing device is required for fixing.

[0003] Existing cutting and fixing devices for extruded aluminum tubes require different clamping components to handle aluminum tubes of various shapes, such as round and square tubes. Changing clamping components is cumbersome and results in low production efficiency. Therefore, we propose a cutting and fixing device for extruded aluminum tubes. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. When using existing cutting and fixing devices for extruded aluminum tubes, different clamping components are required to clamp aluminum tubes of different shapes, such as round and square tubes. Changing the clamping components is cumbersome, resulting in low production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting and fixing device for extruded aluminum tubes includes a mounting platform. A linear guide rail is provided at the top of the mounting platform. A lead screw is rotatably connected inside the linear guide rail. A slider is sleeved around the lead screw and inside the linear guide rail. A fixing platform is installed at the top of the slider. Electric cylinders are symmetrically installed at the top of the fixing platform. A clamping seat is installed at the output end of the electric cylinder. An air bladder is fixed on the inner side wall of the clamping seat. A clamping pad is adhered to the corresponding side of the air bladder. An installation groove is provided inside the fixing platform near the air bladder. A high-pressure air pump is installed inside the installation groove. A connecting pipe is provided at the output end of the high-pressure air pump extending to the air bladder.

[0007] As a preferred embodiment of this utility model, the slider is slidably connected to the linear guide rail and intersects with the screw thread.

[0008] The technical effect of adopting the above-mentioned further solution is that by sliding the slider to the linear guide rail and intersecting the screw thread, the screw can drive the slider to move inside the linear guide rail when it rotates, thereby driving the fixed table to move.

[0009] As a preferred embodiment of this utility model, a drive motor is installed inside the mounting platform near the linear guide rail, and the output end of the drive motor extends into the interior of the linear guide rail and is fixedly connected to the lead screw.

[0010] The technical advantage of adopting the above-mentioned further solution is that by extending the output end of the drive motor into the interior of the linear guide and fixing it to the lead screw, the drive motor can drive the lead screw to rotate, making it more convenient for the fixed platform to move.

[0011] As a preferred embodiment of this utility model, the clamping seat is adapted to the airbag, and the airbag and the clamping seat are fixed by adhesive bonding.

[0012] The technical effect of adopting the above-mentioned further solution is that by adapting the clamping seat to the airbag, it is more convenient for the staff to fix the airbag.

[0013] As a preferred embodiment of this utility model, the clamping pad is made of rubber and the thickness of the clamping pad is 2mm.

[0014] The technical effect of adopting the above-mentioned further solution is that the clamping pad made of rubber material can better clamp and fix the aluminum tube, and the clamping pad with a thickness of 2mm can effectively prevent the protrusion on the outside of the aluminum tube from damaging the airbag.

[0015] As a preferred embodiment of this utility model, a baffle is fixed to the bottom of the fixed platform near the outer side, and the height of the baffle is 25mm.

[0016] The technical effect of adopting the above-mentioned further solution is that, through the design of the baffle, the baffle can block the chips during cutting, so as to prevent the chips from entering the interior of the linear guide through the gap between the mounting table and the fixed table.

[0017] As a preferred embodiment of this utility model, the end of the connecting pipe away from the high-pressure air pump is connected to the airbag, and the connecting pipe is a telescopic flexible hose.

[0018] The technical effect of adopting the above-mentioned further solution is that by connecting the end of the connecting pipe away from the high-pressure air pump to the airbag, the high-pressure air pump can inflate the airbag through the connecting pipe.

[0019] As a preferred embodiment of this utility model, the mounting groove is adapted to the high-pressure air pump, and a plurality of through holes are equidistantly provided on the outer side wall of the fixing platform near the mounting groove, and the through holes are connected to the mounting groove.

[0020] The technical effect of adopting the above-mentioned further solution is that the high-pressure air pump can draw in external air through the through hole by connecting it to the mounting groove.

[0032] Example 1

[0033] like Figure 1-4 As shown, this utility model provides a technical solution: a cutting and fixing device for extruded aluminum tubes, including a mounting platform 1, a linear guide rail 2 at the top of the mounting platform 1, a lead screw 201 rotatably connected inside the linear guide rail 2, a slider 202 sleeved around the lead screw 201 and inside the linear guide rail 2, a fixing platform 3 mounted at the top of the slider 202, the lead screw 201 can drive the slider 202 and the fixing platform 3 to move together when rotating, an electric cylinder 301 is symmetrically mounted at the top of the fixing platform 3, a clamping seat 302 is mounted at the output end of the electric cylinder 301, the electric cylinder 301 can drive the clamping seat 302 to move forward. The displacement is used to initially clamp the aluminum tube. An airbag 303 is fixed on the inner wall of the clamping seat 302. A clamping pad 304 is glued to the corresponding side of the airbag 303. After the airbag 303 expands, it can cooperate with the clamping pad 304 to clamp and fix the aluminum tube for a second time. An installation groove 4 is opened inside the fixing platform 3 near the airbag 303. A high-pressure air pump 401 is installed inside the installation groove 4. The output end of the high-pressure air pump 401 extends to the airbag 303 and is provided with a connecting pipe 402. The high-pressure air pump 401 can deliver air to the inside of the airbag 303 through the connecting pipe 402, so that the airbag 303 can expand.

[0034] Example 2

[0035] like Figure 1-4As shown, the slider 202 is slidably connected to the linear guide rail 2 and threadedly intersecting with the lead screw 201. By sliding the slider 202 to the linear guide rail 2 and threadedly intersecting with the lead screw 201, the lead screw 201 can drive the slider 202 to move inside the linear guide rail 2 when it rotates, thereby driving the fixed platform 3 to move.

[0036] A drive motor 203 is installed inside the mounting platform 1 near the linear guide rail 2. The output end of the drive motor 203 extends into the interior of the linear guide rail 2 and is fixedly connected to the lead screw 201. By extending the output end of the drive motor 203 into the interior of the linear guide rail 2 and being fixedly connected to the lead screw 201, the drive motor 203 can drive the lead screw 201 to rotate, making it easier to move the mounting platform 3.

[0037] The clamping seat 302 is adapted to the airbag 303. The airbag 303 and the clamping seat 302 are fixed by adhesive. The adaptation of the clamping seat 302 to the airbag 303 makes it more convenient for the staff to fix the airbag 303.

[0038] The clamping pad 304 is made of rubber and has a thickness of 2mm. The clamping pad 304 made of rubber can effectively clamp and fix the aluminum tube, and the 2mm thick clamping pad 304 can effectively prevent the protrusion of the aluminum tube from damaging the airbag 303.

[0039] A baffle 305 is fixed to the bottom of the fixed platform 3 near the outer side. The baffle 305 is 25mm high. The design of the baffle 305 allows it to block the chips during cutting, preventing the chips from entering the interior of the linear guide rail 2 through the gap between the mounting platform 1 and the fixed platform 3.

[0040] The end of the connecting pipe 402 away from the high-pressure air pump 401 is connected to the airbag 303. The connecting pipe 402 is a telescopic hose. The connection between the end of the connecting pipe 402 away from the high-pressure air pump 401 and the airbag 303 allows the high-pressure air pump 401 to inflate the airbag 303 through the connecting pipe 402.

[0041] The mounting slot 4 is adapted to the high-pressure air pump 401. Several through holes 403 are equidistantly provided on the outer side wall of the fixed platform 3 near the mounting slot 4. The through holes 403 are connected to the mounting slot 4. Through the through holes 403, the high-pressure air pump 401 can draw in external air through the through holes 403.

[0042] The working process of this utility model is as follows: When using a cutting and fixing device for extruded aluminum tubes to fix the aluminum tubes, the operator first places the aluminum tube between the clamping seats 302 and turns on the electric cylinder 301. The electric cylinder 301 drives the clamping seats 302 to move relative to each other, so that the clamping seats 302 can initially clamp and fix the aluminum tube. Then, the high-pressure air pump 401 is turned on. The high-pressure air pump 401 delivers air into the airbag 303 through the connecting pipe 402, so that the airbag 303 can expand. This allows the airbag 303 to drive the clamping pad 304 to fix the aluminum tube for a second time. Whether it is a round or square aluminum tube, the airbag 303 can cooperate with the clamping pad 304 to clamp it. Compared with the existing cutting and fixing devices for extruded aluminum tubes, this device can clamp aluminum tubes of different shapes more conveniently, without the need to replace the clamping components, thus improving production efficiency.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
