[0028] The following will describe in detail the preferred embodiments of the present utility model with reference to the accompanying drawings, so as to more clearly understand the purpose, features and advantages of the present utility model. It should be understood that the embodiments shown in the drawings are not limitations on the scope of the present utility model, but only to illustrate the essential spirit of the technical solution of the present utility model.

[0029] In the following description, for the purpose of illustrating various disclosed embodiments, certain specific details are set forth to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the relevant art will recognize that the embodiments can be practiced without one or more of these specific details. In other instances, well-known devices, structures and techniques associated with the present application may not be shown or described in detail so as not to unnecessarily obscure the description of the embodiments.

[0030] References to "one embodiment" or "an embodiment" throughout the specification mean that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, appearances of "in one embodiment" or "in an embodiment" throughout the specification are not necessarily all referring to the same embodiment. Additionally, the particular features, structures, or characteristics may be combined in any manner in one or more embodiments.

[0031] In the following description, in order to clearly show the structure and working mode of the present utility model, many directional terms will be used for description. However, words such as "front", "rear", "left", "right", "outer", "inner", "outward", "inward", "up", "down", etc. should be understood as convenient terms and should not be understood as limiting terms.

[0032] Refer to Figures 1 to 4 , the present utility model provides a fixing device for laser processing, and the fixing device includes a base 1, a plurality of sliders 2 and a plurality of jaws 3.

[0033] Refer to Figure 1 , the base 1 is preferably a base 1 with a circular cross-section.

[0034] A plurality of sliders 2 are arranged on the base 1 along the circumferential direction, and the sliders 2 are slidably connected to the base 1 along the radial direction. The number of the sliders 2 can be determined according to the specifications of the product to be processed that needs to be supported and fixed. As Figure 1 shown, there are four sliders 2, and the four sliders 2 are arranged on the base 1 in the front, rear, left and right directions.

[0035] The number of the clamping jaws 3 is the same as that of the sliders 2. Refer to Figure 3 , a support groove for supporting the product is arranged on the left side of the clamping jaw 3. The left side, the front and rear sides and the top of the support groove are all open structures. A first clamping jaw groove 31 is arranged on the right side in the support groove. The length direction of the first clamping jaw groove 31 is the front and rear direction. Each clamping jaw 3 is detachably connected to the top of a corresponding slider 2.

[0036] When the utility model is in use, refer to Figure 1 and Figure 2 , the product 9 to be processed is supported on the support grooves of the clamping jaws 3. The position of each clamping jaw 3 can be adjusted by sliding the slider 2 on the base 1, so that each clamping jaw 3 jointly supports and fixes the product 9 to be processed. The edge of the product 9 to be processed is located above the first clamping jaw groove 31. Since the first clamping jaw groove 31 is arranged on the clamping jaw 3, it is avoided that the laser directly irradiates on the surface where the clamping jaw 3 and the product 9 to be processed are in contact with each other, resulting in processing errors. Instead, when the laser processes the outer contour of the product 9 to be processed, the laser can be injected into the first clamping jaw groove 31. Even if the surface of the first clamping jaw groove 31 is damaged, it will not affect the product. Without moving the product 9 to be processed and the fixing device, the laser can perform the internal processing and cutting of the product shape of the product 9 to be processed at one time, effectively reducing the laser processing error.

[0037] In an embodiment, refer to Figure 3 , a second clamping jaw groove 32 is arranged in the support groove. The length direction of the second clamping jaw groove 32 is the front and rear direction. The second clamping jaw groove 32 is located on the left side of the first clamping jaw groove 31. While the second clamping jaw groove 32 serves as a relief groove, the product edge will not be in contact here, which can reduce errors.

[0038] In an embodiment, the depth of the second clamping jaw groove 32 is deeper than that of the first clamping jaw groove 31.

[0039] The width of the second clamping jaw groove 32 is also preferably wider than that of the first clamping jaw groove 31.

[0040] In an embodiment, refer to Figure 1 and Figure 2 , a plurality of base chutes 11 are arranged on the base 1 along the circumferential direction. The length direction of the base chutes 11 is the radial direction. The top of the base chutes 11 is an open structure. The bottom of the slider 2 is inserted into the base chutes 11 and is slidably connected with the base chutes 11.

[0041] Preferably, the radial outer side of the base chute 11 is also an open structure, so that the slider 2 can be conveniently inserted into and taken out of the base chute 11.

[0042] In an embodiment, the base chute 11 is an inverted T-shaped chute.

[0043] Refer to Figure 3, The fixing device further includes a T-shaped block 4, which is detachably inverted at the bottom of the slider 2, that is, the horizontal section of the T-shaped block 4 is at the bottom and the vertical section is above the horizontal section. The T-shaped block 4 is slidably connected to the base chute 11 to realize the sliding connection between the slider 2 and the base 1.

[0044] In one embodiment, screw holes are respectively provided on the slider 2 and the T-shaped block 4, and the T-shaped block 4 is detachably connected to the slider 2 by an internal hexagonal screw.

[0045] The bottom surface of the slider 2 is generally larger than the top surface of the T-shaped block 4 and the base chute 11. When the slider 2 and the T-shaped block 4 are connected by an internal hexagonal screw 5, the horizontal section of the T-shaped block 4 and the bottom surface of the slider 2 clamp the two side walls of the base chute 11, realizing the positioning of the jaw 3 on the slider 2 on the base 1. When it is necessary to adjust the position of the jaw 3 on the base 1, loosen the internal hexagonal screw and slide the T-shaped block 4 in the base chute 11.

[0046] In one embodiment, referring to Figure 3 and Figure 4 , an avoidance groove 21 is provided on the slider 2, and the avoidance groove 21 is located above the screw hole of the slider 2.

[0047] The space of the avoidance groove 21 above the screw hole of the slider 2 facilitates the use of an internal hexagonal screw wrench to tighten and loosen the internal hexagonal screw.

[0048] In one embodiment, referring to Figure 3 , the T-shaped block 4 is located on the left side of the bottom of the slider 2, and the jaw 3 is located on the right side of the top of the slider 2.

[0049] After the above design, when the slider 2, the jaw 3 and the T-shaped block 4 are integrally fixed on the base 1, a larger-sized product 9 to be processed can be supported.

[0050] In one embodiment, a limit protrusion 22 is provided on the right side of the top of the slider 2, and the length direction of the limit protrusion 22 is the front-rear direction, and the right side surface of the jaw 3 abuts against the limit protrusion 22. This limit protrusion 22 facilitates the installation of the jaw 3.

[0051] When the jaw 3 is installed on the slider 2, a screw can be used for detachable connection.

[0052] In one embodiment, the height of the base chute 11 is higher than the height of the T-shaped block 4. So that when the horizontal section of the T-shaped block 4 and the bottom surface of the slider 2 clamp the two side walls of the base chute 11 to realize the positioning of the jaw 3 on the slider 2 on the base 1, the bottom of the T-shaped block 4 does not contact the inner bottom of the base chute 11, and the four "slider-jaw" are at the same height, keeping the product 9 to be processed horizontal and reducing the processing error.

[0053] In one embodiment, the bottom of the slider 2 has a downward connecting protrusion 23, the connecting protrusion 23 can extend into the base chute 11, and the T-shaped block 4 is detachably inverted at the bottom of the connecting protrusion 23. The height of the base chute 11 is higher than the total height of the T-shaped block 4 and the connecting protrusion 23.

[0054] So that the horizontal section of the T-shaped block 4 and the bottom surface of the slider 2 clamp the two side walls of the base chute 11. When positioning the jaws 3 on the slider 2 on the base 1, the bottom of the T-shaped block 4 does not contact the inner bottom of the base chute 11, and the four "slider-jaw" are at the same height, keeping the product 9 to be processed horizontal and reducing the processing error.
