Description

Technical Field

[0001] This invention belongs to the field of aluminum tube clamping technology, and particularly relates to a rapid clamping device for cutting aluminum tubes. Background Technology

[0002] Aluminum tubes are hollow tubular metal materials made from pure aluminum or aluminum alloys through processes such as extrusion and stretching. They are lightweight, corrosion-resistant, have good thermal conductivity, and are easy to process. Cutting is one of the core steps in aluminum tube processing. Its necessity stems from the actual need to control the size and shape. The quality of the cut end face directly affects the reliability of subsequent processes such as welding and connection. The aluminum tube must be clamped during the cutting process, which is determined by both the material properties and processing requirements. The hollow and thin-walled structure of aluminum tubes results in insufficient rigidity. The cutting force applied by the tool during cutting can cause the tube to vibrate or shift. This can cause surface defects such as end face tilting and increased burrs, or even lead to cutting trajectory deviation or tube breakage. The aluminum tube is fixed in the machine tool table or special fixture by a clamping device. The mechanical force is used to counteract the reaction force generated by cutting, ensuring that the tube maintains positional accuracy during high-speed rotation or reciprocating motion. The evenly distributed clamping force avoids local stress concentration and prevents the thin-walled aluminum tube from deforming due to uneven force.

[0003] Chinese patent publication number 202021467247.1 discloses an aluminum tube clamping device, relating to the field of clamping device technology. It aims to solve the problems of poor adaptability to different tube diameters and the inability to clamp from the middle. The key technical points are: a base, a support arm fixedly mounted on the upper end of the base, a limit rod fixedly mounted between the base and the support arm, a cylinder fixedly mounted at the top of the support arm, a push rod slidably connected to the cylinder, a lifting platform fixedly mounted at the lower end of the push rod, a circular through hole at the left end of the lifting platform through which the limit rod passes, an upper clamping block fixedly mounted at the lower end of the lifting platform, a pressure sensor fixedly mounted on the clamping surface of the upper clamping block, a lower clamping block fixedly mounted at the upper end of the base corresponding to the position below the upper clamping block, and bolts mounted around the base. This aluminum tube clamping device enhances the applicability of the clamping device to aluminum tubes of stationary specifications, supports clamping from any part of the aluminum tube, and has the function of preventing over-clamping.

[0004] However, existing technologies have the following problems when used: Current aluminum tube cutting quick clamping devices typically require aluminum tubes to be passed through holes for fixation, resulting in poor clamping stability, inconvenient clamping and disassembly processes, and high labor intensity for operators, failing to meet the actual needs for rapid and stable clamping of aluminum tubes. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a rapid clamping device for aluminum tube cutting, comprising: A fixed base is provided on the top of the operating table, and the top of the fixed base is provided with a receiving cavity; A fixing seat is fixedly installed at one end of the inner cavity of the receiving cavity, and a locking hook is provided on one side of the fixing seat; A fixing ring is slidably disposed inside the receiving cavity. One end of the fixing ring is provided with a connecting part, one end of the connecting part is provided with a wrist, and one side of the wrist is provided with a hook. The hook, the connecting part, and the wrist form a limiting space that is adapted to the locking hook. The first limiting block and the second limiting block are respectively disposed at both ends of the inner sidewall of the receiving cavity to limit the rotational position of the fixing ring; The curved plates, set on both sides of the fixed base by adjusting the components, are used to support the aluminum tubes; The pressure plate is slidably positioned inside the fixing ring via a movable component, and is used to clamp and fix the aluminum tube in conjunction with the arc-shaped plate.

[0006] Furthermore, two sets of limiting hooks are fixedly connected to the other end of the fixing ring, and the limiting hooks are adapted to the first limiting block.

[0007] Furthermore, a sliding space for accommodating the fixing ring is provided between the second limiting block and the fixing seat.

[0008] Furthermore, the fixed base has an opening on the side near the fixed base to facilitate the movement of the hook.

[0009] Furthermore, both sides of the fixed base are provided with arc-shaped grooves, the bottom of the inner cavity of the arc-shaped groove is provided with a threaded groove, and the two ends of the inner cavity of the arc-shaped groove are provided with guide grooves.

[0010] Furthermore, the adjustment assembly includes a first screw, and the top of the arc-shaped plate has a groove. The first screw is rotatably disposed in the groove, and one end of the first screw passes through the inner cavity of the groove and is threadedly connected to the threaded groove.

[0011] Furthermore, guide rods are fixedly connected to both ends of the bottom of the arc-shaped plate, and the guide rods are slidably disposed in the inner cavity of the guide groove.

[0012] Furthermore, telescopic rods are fixedly connected to both ends of the inner sidewall of the fixed ring, the telescopic ends of the telescopic rods are fixedly connected to the pressure plate, a spring is fixedly connected between the fixed ring and the pressure plate, and a connecting groove is provided on the top of the pressure plate.

[0013] Furthermore, the movable component includes a second screw, and a screw hole is provided at the top center of the fixing ring. The second screw is threaded into the inner cavity of the screw hole, and one end of the second screw abuts against the connecting groove.

[0014] Furthermore, a first gap is provided between the limiting hook and the side wall of the fixing ring, the size of the second limiting block is adapted to the first gap, a second gap is provided in the middle of the first limiting block, and the two sets of telescopic rods are located within the second gap.

[0015] Compared with existing technologies, the aluminum tube cutting quick clamping device of the present invention has the following advantages: 1. The receiving cavity and the fixed ring are fitted with a clearance to limit the radial movement of the fixed ring and prevent it from shifting. When the fixed ring slides to the designated position, the L-shaped locking hook on the fixed base engages with the limiting space enclosed by the hook, connecting part and wrist, thereby limiting the axial movement of the fixed ring. An opening corresponding to the hook is opened on one side of the fixed base. The operator can use the opening to move the elastic wrist to separate the hook from the locking hook, which facilitates the quick pulling of the fixed ring to disassemble the aluminum tube. The second screw can be separated from the screw hole, which facilitates the rotation and opening of the fixed ring, making it convenient to clamp the aluminum tube. The overall operation does not require complicated steps, shortens the clamping and disassembly time, reduces the labor intensity of the operator, and meets the needs of rapid clamping.

[0016] 2. The arc-shaped plate is installed on both sides of the fixed base through the adjustment assembly. When the first screw is rotated, the arc-shaped plate moves up and down along the arc-shaped groove by means of the threaded engagement between the first screw and the threaded groove, and the guiding engagement between the guide rod and the guide groove. The support height can be adjusted according to the diameter of the aluminum tube, so that the arc-shaped surface of the arc-shaped plate fits the bottom of the aluminum tube. The pressure plate is connected to the fixed ring through the telescopic rod and spring. With the cooperation of the second screw of the moving assembly, rotating the second screw can push the pressure plate up and down, forming a clamping space with the arc-shaped plate that is suitable for aluminum tubes of different diameters and wall thicknesses, so as to achieve stable clamping of aluminum tubes of various specifications.

[0023] like Figures 1-8 As shown, the aluminum tube cutting quick clamping device includes: A fixed base 100 is provided on the top of the operating table 200, and a receiving cavity 130 is provided on the top of the fixed base 100; A fixing seat 140 is fixedly disposed at one end of the inner cavity of the receiving cavity 130, and a locking hook 141 is provided on one side of the fixing seat 140; A fixing ring 160 is slidably disposed inside the receiving cavity 130. One end of the fixing ring 160 is provided with a connecting part 170, and one end of the connecting part 170 is provided with a wrist 171. A hook 172 is provided on one side of the wrist 171. The hook 172, the connecting part 170 and the wrist 171 form a limiting space 173 that is adapted to the locking hook 141. The first limiting block 131 and the second limiting block 132 are respectively disposed at both ends of the inner sidewall of the receiving cavity 130 to limit the rotational position of the fixing ring 160; The curved plate 120 is set on both sides of the fixed base 100 through the adjustment component to support the aluminum tube; The pressure plate 190 is slidably disposed inside the fixing ring 160 via a movable component, and is used to clamp and fix the aluminum tube in conjunction with the arc plate 120.

[0024] In this application, the fixing base 100 can be fixed by the existing conventional fixing method of bolt connection, which ensures that the fixing base 100 will not shake during the aluminum tube cutting process and ensures the clamping stability. The receiving cavity 130 has a cylindrical structure, and its inner diameter is adapted to the outer diameter of the fixing ring 160, providing sliding installation space for the fixing ring 160, while limiting the radial movement of the fixing ring 160 and preventing the fixing ring 160 from shifting during the sliding process. The fixing seat 140 can be connected to the fixing base 100 by bolts to ensure the firmness of the connection between the fixing seat 140 and the fixing base 100, and to prevent the fixing seat 140 from loosening due to vibration during the cutting process. A locking hook 141 is integrally formed on one side of the fixing seat 140. The locking hook 141 has an L-shaped structure, and its end faces the outside of the receiving cavity 130. It is used to cooperate with the hook part 172 on the fixing ring 160 to realize the limiting and fixing of the fixing ring 160. The outer wall of the retaining ring 160 is clearance-fitted with the inner wall of the receiving cavity 130 to ensure that the retaining ring 160 can slide axially within the receiving cavity 130. One end of the retaining ring 160 has an integrally formed connecting portion 170, which has a cuboid structure. One end of the connecting portion 170 has an integrally formed wrist portion 171, which has a certain degree of elasticity and can undergo slight deformation to facilitate the engagement and disengagement of the hook portion 172 and the locking hook 141. Specifically, the retaining ring 160, the connecting portion 170, the wrist portion 171, and the hook portion 172 are integrally formed from beryllium copper alloy. The device features high strength and high elasticity. The hook 172, connecting part 170, and wrist part 171 form a limiting space 173 that is adapted to the locking hook 141. The size of the limiting space 173 matches the size of the locking hook 141. When the fixing ring 160 slides to the designated position in the receiving cavity 130, the locking hook 141 can be engaged in the limiting space 173 to achieve axial limiting of the fixing ring 160. The fixing ring 160 limits the aluminum tube to prevent it from moving during the cutting process. A cutting machine 210 is installed on the top of the operating table 200.

[0025] The first limiting block 131 and the second limiting block 132 are symmetrically arranged at both ends of the inner sidewall of the receiving cavity 130 to limit the rotation position of the fixing ring 160. Specifically, the first limiting block 131 and the second limiting block 132 are both arc-shaped. When the fixing ring 160 rotates in the receiving cavity 130, the end of the fixing ring 160 will abut against the first limiting block 131 or the second limiting block 132, thereby preventing the fixing ring 160 from continuing to rotate, ensuring that the fixing ring 160 is always in the correct clamping position, avoiding the aluminum tube clamping displacement caused by the rotation of the fixing ring 160, and the first limiting block 131 and the second limiting block 132 can limit the fixing ring 160 in the receiving cavity 130 to prevent the fixing ring 160 from shifting during rotation.

[0026] The curved surface of the arc plate 120 faces the top of the fixed base 100 and is used to support the aluminum tube from the bottom, providing stable support for the aluminum tube and preventing the cutting cut from being skewed due to gravity during the cutting process. The section assembly is used to adjust the height of the arc plate 120 according to aluminum tubes of different diameters, so that the arc plate 120 can be adapted to aluminum tubes of different specifications, improving the versatility of the device.

[0027] The bottom of the pressure plate 190 has an arc-shaped structure that fits the outer wall of the aluminum tube. It is used to clamp and fix the aluminum tube from the top of the aluminum tube in conjunction with the arc plate 120. The pressure plate 190 and the arc plate 120 are arranged opposite to each other, forming a clamping space. By adjusting the position of the pressure plate 190 by moving the component, it is possible to clamp aluminum tubes of different diameters and wall thicknesses.

[0028] In the example of this application, the other end of the fixing ring 160 is fixedly connected to two sets of limiting hooks 161, which are adapted to the first limiting block 131.

[0029] As a preferred example of this utility model, the limiting hook 161 and the fixing ring 160 are connected by an integral molding method. The two sets of limiting hooks 161 are symmetrically arranged on both sides of one end of the fixing ring 160. Their shape is adapted to the first limiting block 131. When the fixing ring 160 slides in the receiving cavity 130 to a position close to the first limiting block 131, the limiting hook 161 will engage with the first limiting block 131 and form a cooperation with the first limiting block 131, further restricting the rotation and axial movement of the fixing ring 160, and at the same time playing a positioning role for the sliding of the fixing ring 160.

[0030] In the example of this application, a sliding space 133 for accommodating the fixing ring 160 is provided between the second limiting block 132 and the fixing seat 140.

[0031] As a preferred example of this utility model, the thickness of the sliding space 133 is adapted to the thickness of the fixing ring 160, ensuring that the fixing ring 160 can slide into the sliding space 133, providing space for the axial rotation of the fixing ring 160, ensuring that the fixing ring 160 slides smoothly in the sliding space 133, avoiding jamming, and ensuring convenient operation when clamping and disassembling aluminum tubes.

[0032] In the example of this application, the fixed base 100 has an opening 150 on the side near the fixed base 140 to facilitate the movement of the hook 172.

[0033] As a preferred example of this utility model, the position of the opening 150 corresponds to the position of the hook 172. The size of the opening 150 is larger than the size of the hook 172, which makes it easier for the operator to reach into the opening 150 with their hand or a special tool and move the hook 172 to make the hook 172 slightly deformed, thereby separating the hook 172 from the locking hook 141. This facilitates the disassembly of the aluminum tube, improves the efficiency of aluminum tube clamping and disassembly, and reduces the labor intensity of the operator.

[0034] In the example of this application, both sides of the fixed base 100 are provided with arc-shaped grooves 110, the bottom of the inner cavity of the arc-shaped groove 110 is provided with a threaded groove 111, and the two ends of the inner cavity of the arc-shaped groove 110 are provided with guide grooves 112.

[0035] As a preferred example of this utility model, the arcuate groove 110 has the same arcuate direction as the arcuate plate 120 and is used to accommodate the arcuate plate 120. The threaded groove 111 is used to cooperate with the first screw 123 of the adjustment assembly to realize the height adjustment of the arcuate plate 120. Guide grooves 112 are provided at both ends of the inner cavity of the arcuate groove 110, which are used to cooperate with the guide rod 122 at the bottom of the arcuate plate 120 to guide the adjustment of the arcuate plate 120 and prevent the arcuate plate 120 from shifting during the adjustment process.

[0036] In the example of this application, the adjustment component includes a first screw 123, a groove 121 is provided on the top of the arc plate 120, the first screw 123 is rotatably disposed in the groove 121, and one end of the first screw 123 passes through the inner cavity of the groove 121 and is threadedly connected to the threaded groove 111.

[0037] As a preferred example of this utility model, the groove 121 has a cylindrical structure, and its inner diameter is adapted to the outer diameter of the first screw 123. The first screw 123 is rotatably mounted in the groove 121 via a bearing. The outer ring of the bearing is fixedly connected to the inner wall of the groove 121, and the inner ring of the bearing is fixedly connected to the first screw 123, ensuring that the first screw 123 can rotate smoothly in the groove 121 without axial movement. When the first screw 123 is rotated, due to the threaded engagement between the first screw 123 and the threaded groove 111, and the guiding engagement between the guide rod 122 and the guide groove 112, the arc plate 120 will be driven to move up and down along the arc groove 110, thereby realizing the adjustment of the height of the arc plate 120. According to the diameter of the aluminum tube to be cut, the first screw 123 is rotated to adjust the arc plate 120 to a suitable height, so that the arc surface of the arc plate 120 can fit against the bottom of the aluminum tube, ensuring the stability of the aluminum tube support; realizing the adaptable support for aluminum tubes of different diameters, improving the versatility of the device.

[0038] In the example of this application, guide rods 122 are fixedly connected to both ends of the bottom of the arc plate 120, and the guide rods 122 are slidably disposed in the inner cavity of the guide groove 112.

[0039] As a preferred example of this utility model, the guide rod 122 is connected to the arc plate 120 by welding. The outer diameter of the guide rod 122 is adapted to the inner diameter of the guide groove 112, and it is slidably disposed in the inner cavity of the guide groove 112, which can guide the movement of the arc plate 120.

[0040] In the example of this application, telescopic rods 191 are fixedly connected to both ends of the inner sidewall of the fixed ring 160. The telescopic end of the telescopic rod 191 is fixedly connected to the pressure plate 190. A spring 192 is fixedly connected between the fixed ring 160 and the pressure plate 190. A connecting groove 193 is provided on the top of the pressure plate 190.

[0041] As a preferred example of this utility model, the telescopic rod 191 adopts a conventional telescopic structure, including a fixed cylinder and a sliding rod, which is prior art and will not be described in detail. The fixed cylinder is welded and fixed to the inner wall of the fixed ring 160. One end of the sliding rod is slidably inserted into the fixed cylinder, and the other end is welded and fixed to the pressure plate 190 to limit the movement direction of the pressure plate 190, ensuring that the pressure plate 190 can only move up and down radially along the fixed ring 160, and preventing the pressure plate 190 from shifting. The spring 192 is sleeved on the outside of the telescopic rod 191, and its two ends are welded to the inner wall of the fixed ring 160 and the top of the pressure plate 190, respectively. When the spring 192 is in its natural state, the pressure plate 190 is in its initial position. When the pressure plate 190 is subjected to downward pressure, the spring 192 is compressed, generating an upward elastic force. When the pressure disappears, the spring 192 resets, driving the pressure plate 190 back to its initial position for easy clamping next time. The top of the pressure plate 190 is provided with a connecting groove 193, which is cylindrical in shape and is used to cooperate with the end of the second screw 181 of the moving component to ensure that the second screw 181 can stably push the pressure plate 190 to move and prevent the end of the second screw 181 from sliding with the pressure plate 190.

[0042] In the example of this application, the moving component includes a second screw 181, a screw hole 180 is provided at the top center of the retaining ring 160, the second screw 181 is threaded into the inner cavity of the screw hole 180, and one end of the second screw 181 abuts against the connecting groove 193.

[0043] As a preferred example of this utility model, the inner diameter of the screw hole 180 is adapted to the outer diameter of the second screw 181. The second screw 181 is threaded into the inner cavity of the screw hole 180. To prevent the end of the second screw 181 from scratching the pressure plate 190, a rubber pad can be provided at the end of the second screw 181. When the second screw 181 is rotated, due to the threaded engagement between the second screw 181 and the screw hole 180, the second screw 181 will move downward along the axial direction of the screw hole 180, and its end will abut against the pressure plate 190. Within the connecting groove 193, the pressure plate 190 is pushed downwards, compressing the spring 192 and the telescopic rod 191, causing the pressure plate 190 to engage with the arc plate 120 to clamp the aluminum tube. When the second screw 181 is rotated in the opposite direction, the second screw 181 moves upwards, the pressure disappears, the spring 192 returns to its original position, causing the pressure plate 190 to move upwards, releasing the aluminum tube. Furthermore, the second screw 181 can be separated from the screw hole 180, thereby allowing the fixing ring 160 to rotate and achieve the open state.

[0044] In the example of this application, a first gap 162 is provided between the limiting hook 161 and the side wall of the fixing ring 160, the size of the second limiting block 132 is adapted to the first gap 162, a second gap 163 is provided in the middle of the first limiting block 131, and two sets of telescopic rods 191 are located in the second gap 163.

[0045] As a preferred example of this utility model, the size of the second limiting block 132 is adapted to the first gap 162. When the fixing ring 160 slides to a position close to the second limiting block 132, the limiting hook 161 can slide smoothly on the second limiting block 132 through the first gap 162. A second gap 163 is provided between the two sets of first limiting blocks 131, and the two sets of telescopic rods 191 are located in the second gap 163. The size of the second gap 163 is larger than the outer diameter of the telescopic rod 191, ensuring that the telescopic rod 191 will not interfere with the first limiting block 131 during the rotation and retraction process of the fixing ring 160, thus ensuring the normal operation of the telescopic rod 191 and the pressure plate 190.

[0046] In practical use, depending on the diameter of the aluminum tube to be cut, the first screw 123 can be rotated with a screwdriver. Through the threaded engagement of the first screw 123 with the threaded groove 111 and the guiding engagement of the guide rod 122 with the guide groove 112, the arc plate 120 can be adjusted to a suitable height. Then, the aluminum tube is placed on the arc surface of the two arc plates 120, and the fixing ring 160 is pushed to slide in the receiving cavity 130, so that the fixing ring 160 is fitted on the outside of the aluminum tube until the end of the fixing ring 160 enters the sliding space 130. At this time, the locking hook 141 is engaged in the limiting space 173, and the fixing ring is fixed. 160 is fixed at the limit; then, the second screw 181 is screwed into the screw hole 180 and the pressure plate 190 is pushed to move downward, so that the pressure plate 190 cooperates with the arc plate 120 to firmly clamp the aluminum tube; after the aluminum tube is cut, the second screw 181 is rotated in the opposite direction and the second screw 181 is moved out of the screw hole 180, the spring 192 is reset, and the pressure plate 190 is moved upward to release the aluminum tube. Then, the hook part 172 is moved through the opening 150 to separate the hook part 172 from the locking hook 141. The fixing ring 160 is pulled to take out the cut aluminum tube, completing the clamping and cutting operation.

[0047] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
