Description

[0002] Some small-sized micro-tube materials need to be punched and engraved in the thin-walled hollow tube during processing. Since such micro-tube materials have the characteristics of large length-diameter ratio, thin tube wall, softness, and high surface smoothness, etc., good fixing and positioning are required when using laser to process the set surface. Because the tube diameter is very small, high radial height is required during processing. In the related art, a jig is generally used to limit the micro-tube material. Specifically, a limiting groove for accommodating the micro-tube material is formed on the surface of the jig. However, the limiting groove can only be axially limited. In the state that the processing area of the side wall of the micro-tube material faces downward, the micro-tube material needs to be adjusted in the circumferential direction, that is, the micro-tube material in the limiting groove is rotated so that the processing area of the side wall faces upward. Then, the material is clamped by a clamp to keep the posture. During clamping, the workpiece will also move slightly under the clamping force, which is easy to cause the posture to deviate, and further micro-adjustment is required. CONTENT OF THE UTILITY MODEL

[0031] The present application provides a rotating device, referring to Figures 1 to 4 The rotating device comprises a mounting seat 10, a mounting hole 11 is arranged on the mounting seat 10; a rotating part 20 is rotationally arranged in the mounting hole 11, and a through hole 24 for mounting a workpiece is arranged at the center of the rotating part 20; a damping part is arranged between the rotating part 20 and the mounting hole 11; a limiting part 31 is arranged at one end of the rotating part 20, and is used for radially limiting the workpiece; and a clamping part 32 is arranged at one side of the limiting part 31, and is used for clamping the workpiece along the radial direction with the limiting part 31.

[0032] In the embodiment, the mounting seat 10 is rotationally connected with the rotating part 20, the through hole 24 for mounting the workpiece is arranged at the center of the rotating part 20, the workpiece can be inserted into the through hole 24 and one end of the workpiece can be radially limited by the through hole 24, and the other end of the workpiece is clamped by the limiting part 31 and the clamping part 32 arranged at the other end of the rotating part 20, and is radially and axially limited. Then, the workpiece can be circumferentially adjusted by rotating the rotating part 20, and the damping part arranged between the rotating part 20 and the mounting hole 11 provides damping for the rotation of the rotating part 20, so that the rotating part 20 and the workpiece are kept in a set posture, and the mounting and adjusting process is relatively convenient. In the embodiment, the workpiece is first clamped and fixed, and then circumferentially adjusted, which can avoid the workpiece deviation caused by first circumferentially adjusting and then clamping, and the problem of frequent adjustment.

[0033] In some embodiments, the clamping member 32 is connected with the rotating member 20 along the radial direction, and the rotating device further comprises a spring connecting the rotating member 20 and the clamping member 32, and the spring is used to clamp the workpiece by the clamping member 32 and the limiting member 31. In the embodiment, a radial sliding groove can be arranged at the end of the rotating member 20, and the sliding groove extends to the side wall of the rotating member 20. The sliding groove can be a dovetail groove, and a protrusion adapted to the sliding groove is arranged on the clamping member 32, so that the sliding connection of the two can be achieved. A spring can also be arranged in the sliding groove, and an end plate is arranged at the opening of the sliding groove on the side wall of the rotating member 20. One end of the spring abuts against the protrusion, and the other end abuts against the end plate. The elastic force of the spring can provide the clamping force. It is worth noting that the clamping surfaces of the clamping member 32 and the limiting member 31 for clamping the workpiece are arranged along the radial direction to ensure the centering of the workpiece, and a limiting groove can also be arranged on the above-mentioned clamping surface, which is coaxial with the rotating member 20, so that the workpiece can be further centered.

[0034] In some embodiments, the clamping member 32 is connected with the limiting member 31 magnetically, and the rotating device further comprises a magnetic member 33 arranged on the clamping member 32 and / or the limiting member 31, and the magnetic member 33 is used to clamp the workpiece by the clamping member 32 and the limiting member 31. It is worth noting that the clamping member 32 and the limiting member 31 can also clamp the workpiece by magnetic attraction. The clamping member 32 and the limiting member 31 are detachably connected, and the magnetic member 33 can be arranged on the clamping surfaces of the two, and the magnetic member 33 can be a magnet. Of course, the material of either the clamping member 32 or the limiting member 31 can be made of the material such as carbon steel, and a magnet is arranged on the other, and the clamping process can also be completed by the magnetic force of the magnet. Of course, since carbon steel has high hardness, in order to avoid mechanical damage to the workpiece, the clamping member 32 and the limiting member 31 can also be made of high polymer materials such as engineering plastics, and a magnet is arranged on the clamping surface of each. It is worth noting that the magnet cannot be in direct contact with the workpiece when clamping the workpiece, and the magnet can be arranged in the area on both sides of the workpiece. Of course, the limiting groove described above can also be arranged in the embodiment, and the magnet described above can be arranged on both sides of the limiting groove. By detachably arranging the clamping member 32, when the workpiece is installed, the clamping member 32 does not block the through hole 24 in the line of sight, and the upper half of the end of the rotating member 20 is completely visible, and the workpiece is not easily damaged when the workpiece is assembled into the through hole 24, and the workpiece can be ensured to be loaded along the axial direction.

[0035] In some embodiments, the rotating member 20 is a stepped shaft, which comprises a first shaft segment 21 and a second shaft segment 22 connected to each other, the first shaft segment 21 has a smaller outer diameter than the second shaft segment 22, and the first shaft segment 21 is arranged in the mounting hole 11; the rotating device further comprises a circlip 41 arranged on the first shaft segment 21, and the mounting seat 10 is located between the circlip 41 and the second shaft segment 22. In this embodiment, a step is formed at the connection between the first shaft segment 21 and the second shaft segment 22, and the rotating member 20 can be axially positioned by the step and the circlip 41. Of course, an annular groove for mounting the circlip 41 also needs to be arranged on the second shaft segment 22.

[0036] Further, the ends of the first shaft segment 21 and the second shaft segment 22 are arranged outside the mounting hole 11, the limiting member 31 and the clamping member 32 are arranged at the end of the second shaft segment 22, and the outer periphery of the second shaft segment 22 is provided with anti-skid lines. Since the outer diameter of the second shaft segment 22 is larger, the area of the end thereof is larger, which can provide a larger mounting space and operation space for the limiting block and the clamping block. In addition, the second shaft segment 22 can also serve as a handle to facilitate manual rotation of the rotating member 20, and the anti-skid lines on the outer periphery of the second shaft segment 22 can be rolled and pressed to facilitate manual rotation.

[0037] Further, the limiting member 31 and the clamping member 32 are semicircular blocks, the limiting member 31 and the clamping member 32 cooperate with each other, the arc centers of the arc-shaped sides of the two blocks are concentric with the rotating member 20, and the sides of the clamping member 32 and the limiting member 31 for clamping the side wall of the workpiece are respectively provided with a buffer layer. The semicircular shape of the limiting member 31 and the clamping member 32 can keep the barycenter centered when they are mounted on the rotating member 20, avoiding large shaking and speed difference during rotation due to eccentricity. In addition, the above-mentioned buffer layer can be made of soft material, such as polyurethane and other high molecular materials, to reduce the impact of the clamping member 32 and the limiting member 31 on the side wall of the workpiece during clamping, and avoid deformation of the workpiece.

[0038] In some embodiments, the end of the rotating member 20 away from the limiting member 31 is provided with a pointed end 23, and the inner diameter of the through hole 24 at the pointed end 23 is smaller than the inner diameter of the other end. In this embodiment, the above-mentioned pointed end 23 is arranged at the end of the first shaft segment 21, the above-mentioned through hole 24 is arranged in a tapered manner at the pointed end 23, and is arranged in an expanded manner at one end of the second shaft segment 22, so as to load the workpiece and make the workpiece easily extend out of the pointed end 23, exposing the section to be machined. During the loading process of the workpiece, the end thereof located at the pointed end 23 is limited by the tapered structure of the through hole 24, but since there is still a certain gap between the workpiece and the above-mentioned tapered structure, the workpiece as a whole is still prone to swing, and the end of the workpiece away from the pointed end 23 is received by the limiting member 31, ensuring that the workpiece is centered, and then the clamping member 32 is installed, completing the clamping of the workpiece, so that the workpiece is completely limited in the axial and radial directions.

[0039] In some embodiments, the side of the mounting base 10 is further provided with a notch 12 in communication with the mounting hole 11, the notch 12 and the mounting hole 11 form a notch hole, and the rotating device further comprises a connecting piece provided on the mounting base 10, the connecting piece connects two side walls of the notch 12, and the connecting piece is used to adjust the distance between the two side walls.

Further, the laser processing equipment further comprises a motor in driving connection with the rotating piece 20 and a visual camera provided above the mounting base 10. In the embodiment, the motor described above can be a stepping motor, the motor and the rotating piece 20 can be driven through a transmission mechanism, and specifically, a driving wheel can be arranged on the rotating shaft of the motor, the driving wheel is in abutment with the outer periphery of the first shaft segment 21 to achieve transmission. The visual camera described above is used to identify a section to be processed on the workpiece, and when the section to be processed is in an upward posture, the motor can be stopped, so that automatic rotation adjustment of the workpiece can be achieved.
