[0027] Hereinafter, embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and thus are only examples and cannot be used to limit the protection scope of the present application.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0029] In the description of the embodiments of the present application, technical terms such as "first XX" and "second XX", such as "first fixing portion" and "second fixing portion", are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features.

[0030] In order to improve the versatility of the fixture in laser processing so that the same fixture can clamp workpieces with different shapes, according to some embodiments of the present disclosure, a rotary fixture is provided, as Figure 1 Shows a three-dimensional schematic view of some embodiments of a rotary fixture according to the present disclosure, Figure 2 Shows a side schematic view of some embodiments of a rotary fixture according to the present disclosure, Figure 3 Shows an exploded schematic view of some embodiments of a rotary fixture according to the present disclosure.

[0031] The rotating fixture includes a base 1 and a fixing member 2 , wherein the fixing member 2 is rotatably supported on the base 1 with a first axis as a rotation center, and a plurality of first fixing portions 210 and a plurality of second fixing portions 220 are provided in the fixing member 2 .

[0032] It can be understood that the term "fixing part" recorded in the text refers to fixing the relative position relationship between the workpiece to be processed and the rotating fixture during the processing. In some documents, this limiting relationship is also referred to as positioning. For example, the workpiece can be locked and fixed to the corresponding fixing part by using a lock or other similar parts, or the workpiece can be fixed to the corresponding fixing part by using a groove or a bayonet support.

[0033] Among them, multiple first fixing parts 210 and multiple second fixing parts 220 are staggered and arranged around the first axis, so that when the fixing member 2 rotates along the first axis, the multiple first fixing parts 210 and multiple second fixing parts 220 can rotate around the first axis respectively to move to the processing stations in sequence.

[0034] Among them, the first fixing part 210 and the second fixing part 220 are respectively used to fix workpieces with different shapes, so that the workpieces with different shapes can be fixed by the same rotating fixture and moved to the processing station in sequence for processing. Compared with the traditional processing fixture, when performing laser processing, it is necessary to replace the type of fixture according to the different product shapes. The use of a rotating fixture with the aforementioned configuration can avoid the replacement of fixtures when laser processing workpieces with different shapes, thereby improving the efficiency of laser processing.

[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] In one or more embodiments of the present disclosure, Figures 1 to 3As shown, the fixing member includes a fixing plate 21 and a plurality of fixing arms 22. Each fixing arm 22 is connected to the fixing plate 21 in a divergent manner from the center of the fixing plate 21. The first fixing portion 210 is a fixing groove formed in the fixing plate 21. At least one pair of supporting seats 23 is provided on each fixing arm 22. Each supporting seat 23 is movable along the extending direction of the fixing arm 22. The upper surfaces of a pair of supporting seats 23 jointly define the second fixing portion 220. In the embodiment shown in the figure, the first fixing portion 210 is suitable for fixing a cylindrical workpiece with a smaller diameter, such as a ballpoint pen. And the second fixing portion is suitable for fixing a cylindrical workpiece with a larger diameter, such as a water cup. In some other embodiments different from those shown in the figure, the first fixing portion or the second fixing portion may have other structures different from those shown in the figure to be suitable for fixing workpieces with other different shapes. For example, when the workpiece to be processed is easily magnetically adsorbed, the first fixing portion or the second fixing portion can be configured as a planar structure with a magnet. When the workpiece to be processed is a planar product, the first fixing portion or the second fixing portion can be configured as a holding slot or an elastic clamping slot. In some embodiments of the present disclosure, the fixing arm 22 and the fixing plate 21 can be connected in many ways. For example, as shown in the figure, the fixing arm 22 and the fixing plate 21 are detachably connected by fasteners, or the fixing arm 22 is integrally provided on the fixing plate 21. The fixing arm 22 can be arranged above the fixing plate 21 as shown in the figure or arranged on the fixing plate 21 differently from the illustration, for example, arranged on the side of the fixing plate 21.

[0037] In one or more embodiments of the present disclosure, as Figures 1 to 3 shown, the fixing plate 21 is a disc, the first axis is the center line of the disc, the fixing groove (the first fixing portion 210) is arranged along the radial direction of the disc, each fixing arm 22 extends radially outward from the center of the disc, and the fixing groove (the first fixing portion 210) and the fixing arm 22 are circumferentially offset along the disc.

[0038] Figure 4 The side view of the fixing arm according to some embodiments of the present disclosure is shown. In one or more embodiments of the present disclosure, the supporting seats 23 on each fixing arm 22 have different supporting heights. For example, in the embodiment shown in the figure, a pair of supporting seats 23 is provided on each fixing arm 22, and the supporting heights of the two supporting seats 23 on each fixing arm 22 are different. Thus, by moving the distance between the two supporting seats 23, the support for workpieces with different shapes can be realized. For example, when the workpiece to be supported is frustum-shaped, since the taper of different frustums is different, by moving the distance between the two supporting seats 23, it can be realized that the central axis of the frustum with different tapers is kept parallel to the horizontal plane for convenient laser processing.

[0039] In one or more embodiments of the present disclosure, a V-shaped groove is formed on the upper surface of each support base 23, and the V-shaped groove defines a second fixing portion 220, so that the outer periphery of the columnar workpiece is supported through each V-shaped groove. In this embodiment, the support height of the support base 23 is defined by the side wall of the V-shaped groove.

[0040] In one or more embodiments of the present disclosure, the fixing grooves (the first fixing portions 210) and the fixing arms 22 are alternately arranged along the circumferential direction of the disc.

[0041] In one or more embodiments of the present disclosure, in a part not shown in the figure, a scale is further provided on the upper surface of the fixing arm 22, and the scale is arranged along the extending direction of the fixing arm 22, so as to facilitate determining the distance between a pair of support bases 23. When processing multiple workpieces with the same shape at the same time, the distance between a pair of support bases 23 can be quickly positioned.

In one or more embodiments, the fixing member 2 further includes a connecting member 24, and the connecting member 24 is fixedly connected to the center of the disc. Each fixing arm 22 is detachably connected to the connecting member 24 through a rabbet fit. For example, as shown in the figure, a rabbet portion 221 is provided on the fixing arm 22, so that it can be quickly rabbet-positioned and connected to the boss 241 on the side surface of the connecting member 24, thereby improving the assembly efficiency. By configuring the fixing arm 22 to be detachable, it is convenient for packaging and transportation.

[0043] In one or more embodiments of the present disclosure, a sliding groove 222 is formed on the fixing arm 22, and the support base 23 is slidably connected in the sliding groove through a slider 232.

[0044] Figure 6 The three-dimensional schematic view of another angle of the fixing disc according to some embodiments of the present disclosure is shown. In one or more embodiments of the present disclosure, the fixing disc 21 is detachably connected to the base 1. A fixing groove (the first fixing portion 210) is provided in the first end face of the fixing disc 21, and a plurality of groups of fixing holes 211 arranged in a divergent manner are provided in the second end face of the fixing disc 21, so that the fixing disc 21 can be turned over and used, and tools with other different shapes can be fixed through the fixing holes 211, further improving the application range of the present rotary fixture.

[0045] Figure 7Shows an exploded schematic diagram of a base according to some embodiments of the present disclosure. The rotary clamp further includes a motor 3, and the motor 3 is drivingly connected to the first fixing member 210. For example, as shown in the figure, it is drivingly connected to a rotating shaft 5 below the first fixing member through a belt 4. The output shaft 30 of the motor 3 outputs torque to the rotating shaft 5 through the belt, and drives the first fixing member 210 to rotate around the first axis. In a specific embodiment, the motor 3 is a stepper motor.
