Description

Technical Field

[0001] The invention belongs to the technical field of aluminum tube processing and polishing, and in particular relates to a polishing device for aluminum tube processing. Background Art

[0002] Aluminum has excellent thermal conductivity and can dissipate heat into the air faster under the same conditions, effectively shortening the equipment preheating time and improving overall energy efficiency. The application of aluminum greatly improves the heat conduction efficiency of the radiator, allowing the heat dissipation aluminum equipment to dissipate heat into the air faster, effectively shortening the equipment preheating time and improving overall energy efficiency.

[0003] After aluminum is processed into heat dissipation aluminum tubes, a grinding device is usually required to grind the aluminum tube mouth from the original rough and unsmooth surface to a smooth aluminum tube suitable for processing, such as grinding the surface of the alloy bar to remove the oxide layer on the surface of the aluminum tube. During the grinding process, the existing device has different diameters of aluminum tubes to be polished, but it is not convenient to adjust the grinding clamp according to the required width, which leads to a limited application range of the device. In addition, it is not convenient to adjust the position of the grinding disc during grinding, and it cannot be used for aluminum tubes of different diameters. Summary of the invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a grinding device for aluminum tube processing, which at least partially solves the problems raised in the above background technology. By setting the grinding assembly, the sleeve can be driven to move up and down, thereby adjusting the position of the grinding piece in the horizontal direction, and the inside of aluminum tubes with different diameters can be ground. At the same time, the setting of the first clamping assembly and the second clamping assembly can also clamp and fix aluminum tubes with different diameters.

[0005] The technical solution adopted by the present invention is as follows: a grinding device for aluminum tube processing, comprising a base plate for supporting and fixing the aluminum tube, a first support plate and a fixing assembly being installed on the base plate, the first support plate being arranged on the outside of the fixing assembly and placed perpendicular to the base plate, a connecting plate being installed on the upper end of the first support plate, a driving assembly being installed on the bottom wall of the connecting plate, a grinding assembly being provided on the bottom wall of the driving assembly, and the grinding assembly being arranged above the fixing assembly.

The connecting rod is movably installed on any group of mounting plates, and the grinding piece is movably installed on one end of the connecting rod.

[0007] Furthermore, a limit groove is provided on the bottom wall of the turntable, a limit plate is movably engaged in the limit groove, and the polishing member is connected to the limit plate at the bottom.

[0008] In a further embodiment, a second support plate is installed on the bottom wall of the turntable, a third support plate is connected to the bottom wall of the second support plate, a first hydraulic rod is installed on the third support plate, and a movable end of the first hydraulic rod is connected to the bottom wall of the sleeve; The first hydraulic rod works to push the sleeve to move upward along the limit rod, the sleeve drives the mounting plate to move upward, and the mounting plate drives one end of the connecting rod to move upward. Since the movement of the grinding piece is limited by the limit plate and the limit groove, when one end of the connecting rod moves upward, the other end pushes the grinding piece to move outward along the limit groove, so that the inside of the aluminum tube with a larger diameter can be ground; The first hydraulic rod works to push the sleeve to move downward along the limit rod, the sleeve drives the mounting plate to move downward, the mounting plate drives one end of the connecting rod to move downward, when one end of the connecting rod moves downward, the other end of the connecting rod drives the grinding piece to move inward along the limit groove, so that the inside of the aluminum tube with a smaller diameter can be ground.

[0009] Among them, the bottom wall of the connecting plate is provided with an annular groove, and the driving assembly includes a motor and a clamping plate. The motor is arranged at the center position of the bottom wall of the connecting plate, and the output shaft end of the motor is connected to the center of the turntable. The upper end of the clamping plate is movably clamped in the annular groove, and the upper end of the clamping plate is provided with a ball to reduce the friction between the annular groove, and the lower end of the clamping plate is connected to the upper wall of the turntable; the motor drives the turntable to rotate, and the turntable drives the clamping plate to rotate along the annular groove, and at the same time drives the grinding part to rotate.

[0013] In a further embodiment, an elastic member is installed on the inner side wall of the clamping plate to facilitate clamping and fixing the aluminum tube; Pull the pulling plate and move it away from the baffle, the spring is stretched, and the pushing rod drives the clamping plate to move towards the arc plate. The spacing between the clamping plates becomes larger, and the lower end of the aluminum tube to be polished is placed on the upper wall of the pushing plate and arranged between the two groups of clamping plates. Then the pulling plate is released, and under the action of the spring, the pulling plate drives the clamping plate to move away from the arc plate through the pushing rod to clamp the lower end of the aluminum tube. After clamping, the second hydraulic rod works to drive the pushing plate to move up, and the pushing plate drives the clamping assembly to move up, and the polishing piece is inserted into the aluminum tube.

[0014] After adopting the above structure, the beneficial effects of the present invention are as follows: (1) When the grinding assembly moves upward, the sleeve drives the mounting plate upward, the mounting plate drives one end of the connecting rod upward, and the grinding piece moves outward along the limit groove, so that the inside of the aluminum tube with a larger diameter can be ground; when the grinding assembly moves downward, the sleeve drives the mounting plate downward, the mounting plate drives one end of the connecting rod downward, and the grinding piece moves inward along the limit groove, so that the inside of the aluminum tube with a smaller diameter can be ground.

[0015] (2) When the spring is stretched, the distance between the clamping plates becomes larger, and the lower end of the aluminum tube to be polished is placed on the upper wall of the pushing plate. After the spring returns to its initial state, the pulling plate drives the clamping plate to move away from the arc plate through the pushing rod, making it easier to clamp the lower end of the aluminum tube.
