Description

Technical Field

[0001] This utility model relates to the field of rotary worktable technology, specifically an adjustable rotary worktable for a laser engraving machine. Background Technology

[0002] After the workpiece is processed, it needs to be laser-engraved with corresponding patterns or related parameters on its surface. A laser engraving machine is a very useful device. Since the surface of a cylindrical workpiece is curved, when engraving some cylindrical workpieces, it is necessary to rotate the workpiece to achieve "unfolding" engraving (similar to "flattening" the cylindrical surface before processing).

[0003] Current rotary worktables, while able to rotate cylindrical workpieces after clamping and fixing them, cannot adjust the clamping position of the workpieces in real time. If it is necessary to engrave "continuous patterns around the entire circumference" or "patterns covering the clamping obstruction area", traditional worktables can only be stopped and re-clamped (changing the clamping position), which is quite troublesome. Utility Model Content

[0007] The drive assembly includes a motor, a driven gear mounted on the outer wall of the rotating tube, and a driving gear mounted on one end of the motor output shaft.

[0008] The driving gear meshes with the driven gear.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4The present invention provides an adjustable rotary worktable for a laser engraving machine, comprising: a base 1 and a rotating shaft 2 rotatably mounted on the top outer wall of the base 1; and an electric rotary table 3 mounted on the bottom inner wall of the base 1. The rotating component of the electric rotary table 3 is connected to the bottom of the rotating shaft 2, and a first conductive slip ring 4 is mounted on the outer wall of the rotating shaft 2. A controller 5 is mounted on one side outer wall of the base 1, and a mounting plate 6 is mounted on the top of the rotating shaft 2. A rotating tube 7 is rotatably mounted on one side outer wall of the mounting plate 6, and a second conductive slip ring 8 is mounted on the outer wall of the rotating tube 7. Multiple equally spaced moving components 9 are mounted on the outer wall of the rotating tube 7, and a drive component 10 is provided on one side outer wall of the mounting plate 6.

[0020] It should be noted that the workpiece 11 can be passed through the rotating tube 7, and multiple moving components 9 can be adjusted by the controller 5 to move closer to each other to clamp the workpiece 11. At this time, the rotating tube 7 can be rotated by the drive component 10, which in turn drives the workpiece 11 to rotate, making it convenient to perform "unfolding" engraving on the surface of the workpiece 11. When it is necessary to engrave "full-circumference continuous patterns" or "patterns covering the clamping and obstructing areas", multiple moving components 9 can be used to move the workpiece 11 in the rotating tube 7 in a synchronized manner, thereby changing the clamping position without stopping the machine and re-clamping, which is more convenient. The rotating shaft 2 can also be rotated by the electric rotary table 3, which can then drive the workpiece 11 to turn around and change position, making it convenient to engrave "full-circumference continuous patterns".

[0021] In a preferred embodiment, the moving component 9 includes an electric actuator 901, a mounting bracket 902 mounted on the piston rod end of the electric actuator 901, and a belt conveyor 903 mounted on the bottom of the mounting bracket 902.

[0022] It should be noted that the electric push rod 901 can push the belt conveyor 903 closer to the surface of the workpiece 11, thereby pressing the belt conveyor 903 onto the surface of the workpiece 11.

[0023] In a preferred embodiment, the drive assembly 10 includes a motor 1001, a driven gear 1002 mounted on the outer wall of the rotating tube 7, and a drive gear 1003 mounted on one end of the output shaft of the motor 1001; the drive gear 1003 meshes with the driven gear 1002.

[0024] It should be noted that the motor 1001 can drive the drive gear 1003 to rotate, which in turn drives the driven gear 1002 to rotate, which in turn drives the rotating tube 7 to rotate.

[0025] In a preferred embodiment, fixing holes are provided at all four corners of the bottom outer wall of the base 1.

[0026] It should be noted here that this is to facilitate the fixing of base 1.

[0027] In a preferred embodiment, the electric push rod 901 and the belt conveyor 903 are both connected to the inner slip ring rotor of the second conductive slip ring 8 via wires, and the inner slip ring stator of the second conductive slip ring 8 and the motor 1001 are both connected to the inner slip ring rotor of the first conductive slip ring 4 via wires.

[0028] It should be noted here that this can prevent the problem of wires getting tangled in rotating parts.

[0029] Working principle:

[0030] Workpiece clamping and initial positioning

[0031] The cylindrical workpiece 11 is passed through the inside of the rotating tube 7. The controller 5 issues a command to make multiple moving components 9 on the outer wall of the rotating tube 7 move synchronously: the electric push rod 901 extends, pushing the mounting bracket 902 and the belt conveyor 903 closer to the surface of the workpiece 11, until the belt surface of the belt conveyor 903 presses the workpiece 11 (the pressure is controlled by the stroke of the electric push rod to ensure stable clamping and no damage to the workpiece), thus completing the initial clamping.

[0032] Basic rotary engraving (unfolding processing)

[0033] Start drive assembly 10: Motor 1001 runs, driving drive gear 1003 to rotate, and through gear meshing, drives driven gear 1002 and rotating tube 7 to rotate synchronously (speed is adjusted by controller 5 to adapt to engraving precision requirements), and then through the friction of moving assembly 9, drives workpiece 11 to rotate, realizing "unfolding" engraving (that is, the cylindrical surface is "flattened" into a planar path for laser processing as it rotates).

[0034] Assisted repositioning: If it is necessary to carve continuous patterns around the entire circumference, the electric rotary table 3 drives the rotating shaft 2 to rotate (it can rotate 360°, and the accuracy is guaranteed by the parameters of the electric rotary table itself), which drives the mounting plate 6, the rotating tube 7 and the workpiece 11 to turn around as a whole, ensuring that there are no blind spots for carving at both ends of the workpiece.

[0035] The clamping position is adjusted in real time (avoiding obstructed areas).

[0036] When the laser is about to reach the clamping and blocking area of ​​a certain moving component 9, the controller 5 triggers an adjustment command:

[0037] All moving components 9 belt conveyors 903 start synchronously (with the same direction of rotation), and drive the workpiece 11 to move axially by the friction between the belt and the surface of the workpiece 11 (the moving distance is preset by the controller, such as 5mm), so that the original blocked area is removed from the clamping position.

[0038] Once the device is in place, the belt conveyor 903 stops, maintaining the clamped state, and the laser continues to engrave the previously blocked area without needing to stop the machine and re-clamp it.

[0039] Circuit connection and anti-tangling design

[0040] The electric push rod 901 and the belt conveyor 903 are connected to the slip ring rotor of the second conductive slip ring 8 (rotating with the rotating tube 7), and their stators are connected to the slip ring rotor of the first conductive slip ring 4 (rotating with the rotating shaft 2) through wires.

[0041] The stator of the first conductive slip ring 4 is connected to an external power supply and controller 5 to ensure that when the rotating tube 7 and the rotating shaft 2 rotate, there are no wires tangled in the power supply and signal transmission of each electric component, thus ensuring continuous operation.

[0042] Overall fixation and stability guarantee

[0043] The base 1 is fastened to the laser engraving machine table through the fixing holes (with diameter matching M8 bolts) at the four corners of the bottom, which avoids engraving deviation caused by the shaking of the base when the workpiece rotates and moves, and provides rigid support for the entire process.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
