Description

Technical Field

[0001] The utility model relates to the technical field of titanium tube processing, in particular to a processing clamping device for preventing titanium tube deformation. Background Art

[0002] Titanium tubes are light, high in strength and have excellent mechanical properties. They are widely used in heat exchange equipment, such as shell-and-tube heat exchangers, coil heat exchangers, serpentine heat exchangers, condensers, evaporators and transmission pipelines. Many nuclear power industries use titanium tubes as standard tubes for their units.

[0003] During the processing of titanium tubes, the tube body is subjected to increased pressure, which makes it easy for the two ends to warp or deform, so a clamping device is needed to fix it. During processing, traditional clamping devices can easily allow debris to enter the drive mechanism, causing it to get stuck or generate loud noises. Therefore, the existing device needs to be improved to meet actual needs. Utility Model Content

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the utility model provides a clamping device for processing to prevent titanium tube deformation. The device has the function of clamping the head and tail ends of the titanium tube respectively, so as to achieve a better clamping effect and avoid deformation of the head and tail of the titanium tube during processing. At the same time, the U-shaped slider and the clamping plate with adjustable spacing are convenient for clamping and fixing titanium tubes of different diameters. The clamping plate and the U-shaped slider are protected by a rubber plate to avoid scratches on the outer circumference of the U-shaped slider by the inner wall of the clamping plate. The motor and the positive and negative threaded rods are arranged at the bottom of the base to avoid debris entering the motor or the positive and negative threaded rods to cause jamming or generate loud noise, etc., thereby solving the above-mentioned technical problems.

[0006] (II) Technical solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a clamping device for processing to prevent titanium tube deformation, comprising a base, a limiting plate is installed on the upper surface of the base, and a sliding groove is opened at the bottom end, a U-shaped slider is installed inside the limiting plate, a clamping plate is installed on the top of the U-shaped slider, and a moving block is installed on the bottom end, a vertical plate is installed at the bottom end of the base, a motor is installed on the side of the vertical plate, and positive and negative threaded rods are installed at the axis of the motor.

[0008] Preferably, four groups of vertical plates are relatively fixedly installed at the bottom end of the base, and motors are installed through the sides of two groups of vertical plates. Forward and reverse threaded rods are fixedly installed at the axis of the motor, and the other ends of the forward and reverse threaded rods are rotatably installed on the inner sides of the other two groups of vertical plates.

[0009] Through the above technical solution, the motor is first supported by two sets of vertical plates, and the vertical plates, motor, and positive and negative threaded rods are arranged at the bottom of the base. This is to prevent debris from entering the motor or positive and negative threaded rods and causing jamming or generating loud noise when processing the titanium tube.

[0010] Preferably, the moving blocks are relatively arranged in four groups, and two of the moving blocks are relatively threadedly installed on the outer circumference of the positive and negative threaded rods, and the top of the moving block is fixedly connected to the bottom of the U-shaped slider, and the U-shaped slider is arranged in four groups.

[0011] Through the above technical scheme, after starting the motor, the motor rotor end rotates to drive the positive and negative threaded rods to rotate, and the positive and negative threaded rods drive the two relative groups of moving blocks to move relative to each other on the outer circumference of the positive and negative threaded rods, drive the corresponding U-shaped sliders to move relative to each other, and drive the splints to move relative to each other, thereby achieving the effect of fixing and clamping the titanium tube. At the same time, the four groups of U-shaped sliders can clamp the head and tail ends of the titanium tube respectively at the same time, so that the clamping effect is better and the problem of deformation of the head and tail of the titanium tube during processing is avoided. At the same time, the adjustable spacing of the U-shaped sliders and splints is convenient for clamping and fixing titanium tubes of different diameters.

[0012] Preferably, four groups of limit plates are relatively fixedly installed on the upper surface of the base, and a U-shaped slider is slidably installed inside each group of limit plates.

[0013] Through the above technical solution, when the moving block drives the U-shaped slider to move, the top of the U-shaped slider slides synchronously inside the limiting plate, and the moving path of the top of the U-shaped slider is limited by the limiting plate, thereby maintaining the stability of the U-shaped slider's movement process.

[0014] Preferably, the interior of the bottom end of the U-shaped sliding block is slidably connected to the interior of the sliding groove.

[0015] Through the above technical solution, when the moving block drives the U-shaped slider to move, the bottom end of the U-shaped slider slides synchronously inside the slide groove, thereby increasing the stability of the bottom of the U-shaped slider when sliding.

[0016] Preferably, the clamping plates are provided in four groups and are fixedly mounted on the top of the U-shaped slider, and a rubber plate is fixedly mounted inside the clamping plates.

[0017] Through the above technical solution, when the U-shaped slider moves to drive the clamp to clamp the titanium tube, the clamp and the U-shaped slider are protected by the rubber plate to avoid the problem of the inner wall of the clamp scratching the outer peripheral surface of the U-shaped slider.

After starting the motor, the motor rotor end rotates to drive the positive and negative threaded rods to rotate, and the positive and negative threaded rods drive the two relative groups of moving blocks to move relative to each other on the outer circumference of the positive and negative threaded rods, drive the corresponding U-shaped sliders to move relative to each other, and drive the clamping plates to move relative to each other, thereby achieving the effect of fixing and clamping the titanium tube. At the same time, the four groups of U-shaped sliders can clamp the head and tail ends of the titanium tube respectively at the same time, so as to achieve a better clamping effect and avoid the problem of deformation of the head and tail of the titanium tube during processing. At the same time, the U-shaped sliders and clamping plates with adjustable spacing are convenient for clamping and fixing titanium tubes of different diameters.
