Detailed description of the specific implementation

[0047] The terms used in the following embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. As used in the specification and appended claims of the present application, the singular forms "a", "an", "the above", "the", and "this" are also intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" used in the present application refers to and includes any or all possible combinations of one or more of the listed items.

[0048] Hereinafter, the terms "first" and "second" are only used for descriptive purposes, and cannot be construed as implying or indicating relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0049] The technical solutions of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0050] See Figure 1 Figure 1 , an embodiment of the present application discloses a jaw 40 mechanism for assisting laser engraving, including: a fixing frame 10, a driving member 20, a deceleration assembly 30, and a jaw 40. The driving member 20 is a servo motor disposed at one end of the fixing frame 10. One end of the deceleration assembly 30 is connected to the driving member 20, and the other end is connected to the jaw 40, which functions to reduce the rotation speed when the driving member 20 drives, so as to improve the accuracy of rotational positioning.

[0051] See Figure 2 and Figure 3 Figure 2 and Figure 3 , the deceleration assembly 30 includes a connecting member 31 and a toothed groove member 32. One end of the connecting member 31 close to the driving member 20 is provided with a sleeve structure for sleeving and connecting the rotating end of the driving member 20. The toothed groove member 32 is sleeved on the connecting member 31. The other end of the connecting member 31 away from the driving member 20 is provided with a clamping groove 311 for slidably clamping the jaw 40. One end of the jaw 40 opposite to the toothed groove member 32 is provided with teeth 41, and the teeth 41 are located in the tooth grooves 321 of the toothed groove member 32. When the connecting member 31 rotates with the driving member 20, the jaw 40 is driven to rotate through the toothed groove member 32. Here, it is worth mentioning that during the process of the toothed groove member 32 driving the jaw 40 to rotate, the teeth 41 will generate a certain frictional resistance with the tooth grooves 321 to reduce the rotation speed transmitted from the driving member 20 to the jaw, so as to improve the accuracy of the rotational positioning of the jaw during the laser engraving process.

[0052] Specifically, one end of the driving member 20 sleeved by the connecting member 31 is provided with a first fixing hole 201. The connecting member 31 is correspondingly provided with a second fixing hole 312 corresponding to the first fixing hole 201. The corresponding jaw 40 mechanism further includes a second fixing member 70 for sequentially passing through the second fixing hole 312 and the first fixing hole 201 to fixedly connect the driving member 20 and the connecting member 31, and at the same time facilitate the disassembly of the driving member 20 and the connecting member 31. The tooth grooves 321 are arc-shaped grooves (as shown in Figure 3 Figure 3 ), the teeth 41 are arranged in parallel as multiple. During assembly, the multiple teeth 41 arranged in parallel are clamped and fixed in the toothed groove member 32, which can increase the stability of the jaw 40 when the jaw 40 rotates.

[0053] See Figure 2 Figure 2 , the jaw 40 includes a clamping and sliding member 42 and a clamping jaw 43. The clamping and sliding member 42 is used for clamping in the clamping groove 311, and one end is provided with teeth 41, and the other end is connected to the clamping jaw 43.

[0054] Among them, when assembling or adjusting the size of the jaw 40, the operator can insert the engaging slider 42 into the engaging groove 311 to slide and adjust the position of the engaging slider 42, so as to adjust the engaging size of the engaging jaw 43. After adjusting the engaging size, the toothed groove member 32 is covered on the teeth 41 to realize the meshing of the teeth 41 with the toothed groove member 32, so as to assemble the jaw 40 of this structure and flexibly adjust the size of the jaw 40.

[0055] See Figure 2 and Figure 3 , in order to increase the applicability of the jaw 40 mechanism to workpieces 80 of different sizes, in this embodiment, the engaging jaw 43 is provided with a plurality of adjusting and fixing holes 431 relative to the engaging slider 42, which can facilitate the operator to select different fixing holes to fix the engaging slider 42 and the engaging jaw 43 based on the sizes of different workpieces 80, so as to increase the applicability of the jaw 40 mechanism to workpieces 80 of different sizes.

[0056] Here, it is worth mentioning that a first abutting member 432 and a second abutting member 433 are provided on the engaging jaw 43, and the second abutting member 433 is farther from the central axis of the engaging jaw 43 than the first abutting member 432.

[0057] Among them, the first abutting member 432 and the second abutting member 433 are provided on the engaging jaw 43, which can be applicable to two different sizes of workpieces 80 at the same time, and with the cooperation of a plurality of adjusting and fixing holes 431 provided, the applicability of the jaw 40 mechanism to workpieces 80 of different sizes can be further increased.

[0058] In addition, see Figure 1 , in order to facilitate ensuring the stability of the workpiece 80 during engraving rotation, in this embodiment, a support assembly 50 is further included, which is arranged at the other end of the fixing frame 10 and is used to support the other end of the workpiece 80 away from the clamping jaw.

[0059] See also Figure 4 , the support assembly 50 includes a support frame 51 and a supporting component 52. The support frame 51 is used to connect to the other end of the fixing frame 10, and the supporting component 52 is located at one end of the support frame 51 close to the jaw 40. During laser engraving, one end of the workpiece 80 is used to be clamped and fixed in the jaw 40, and the other end of the workpiece 80 is used to be placed on the supporting component 52 to maintain the overall stability of the workpiece 80 during rotation.

[0060] See again Figure 5, the supporting component 52 includes rollers 521 and a first fixing member 522. Two rollers 521 are provided and are slidably abutted against the surface of the workpiece 80 for synchronously rotating with the rotation of the workpiece 80. The first fixing member 522 is used to indirectly abut and fix the rollers 521 to adjust the rotational flexibility of the rollers 521. Correspondingly, a through groove 511 for accommodating the two sliding rollers 521 is provided on the support frame 51. As Figure 6 shown, the two rollers 521 are exposed from the through groove 511. The first fixing member 522 is located on the side of the support frame 51 and is used to penetrate the support frame 51 to approach or abut the two rollers 521. For example, when it is necessary to reduce the rotational flexibility of the rollers 521, the two rollers 521 can be abutted by manually rotating the first fixing member 522.

[0061] See Figure 1 and Figure 5 , in order to facilitate adjusting the height of the supporting component 52 relative to the jaw, in this embodiment, a height adjustment component 60 is further included. The height adjustment component 60 includes a box body 61, an adjustment rod 62, a rotating member 63, and a moving member 64. One end of the box body 61 is fixed to the other end of the fixing frame 10. One end of the adjustment rod 62 is connected to the rotating member 63, and the other end is located inside the box body 61. The moving member 64 is located inside the box body 61 and is sleeved and connected to the adjustment rod 62.

[0062] Among them, a limiting member 65 is provided at the part where the adjustment rod 62 is sleeved with the moving member 64 (the outer shape can be as shown in Figure 5 ), and a limiting groove 642 is correspondingly provided on the moving member 64 to accommodate and engage the limiting member 65. A linear adjustment slot hole 611 is provided on one side of the box body 61. One end of the support frame 51 away from the supporting component 52 is connected to one end of the moving member 64 through the adjustment slot hole 611. The adjustment rod 62 rotates through the rotating member 63 and the limiting groove 642 engages the limiting member 65 to rotate relative to the moving member 64. The moving member 64 drives the support frame 51 to perform a linear motion relative to the adjustment slot hole 611 based on the rotation of the adjustment rod 62.

[0063] Specifically, the moving member 64 can be set as a lead screw. The moving member 64 is sleeved on the adjustment rod 62 and can move up and down on the moving member 64 with the rotation of the adjustment rod 62 based on the limitation of the limiting member 65. Of course, there is no limitation here as long as the same function is achieved.

[0064] In order to guide and limit the linear motion of the moving member 64, in this embodiment, the height adjustment component 60 further includes: a guide rod 66, which is fixed inside the box body 61 and is parallel to the adjustment rod 62. A through hole 643 is provided at the other end of the corresponding moving member 64 and is sleeved on the guide rod 66 through the through hole 643, which can play a role in guiding and limiting when the moving member 64 moves on the adjustment rod 62.

[0065] In summary, a jaw 40 mechanism for assisting laser engraving machines disclosed in the embodiments of the present application, by setting the deceleration assembly 30 to include a connecting member 31 and a toothed groove member 32, one end of the connecting member 31 is connected to the driving member 20, and the other end is provided with a clamping groove 311 to engage with the teeth 41 of the jaw 40, can achieve a certain effect of reducing the rotation speed when the driving member 20 rotates through the deceleration assembly 30, so as to improve the accuracy of rotational positioning; by setting the support assembly 50 to include a support frame 51 and a supporting assembly 52, it can be used to support the other end of the workpiece 80 in cooperation with the clamping of the jaw 40 during laser engraving; setting the supporting assembly 52 to include rollers 521 and a first fixing member 522, and the rollers 521 are provided in two, and the two rollers 521 are accommodated in the through groove 511, which can realize sliding support of one end of the workpiece 80 through the two rollers 521 to cooperate with the clamping jaw to drive the workpiece 80 to rotate, further ensuring the stability of the workpiece 80 during rotation; by setting the height adjustment assembly 60 to include a box body 61, an adjustment rod 62, a rotating member 63 and a moving member 64, one end of the adjustment rod 62 is connected to the rotating member 63, and the other end passes through the box body 61, the moving member 64 is sleeved on the adjustment rod 62 in the box body 61, the adjustment rod 62 can rotate relative to the moving member 64 through the rotation of the rotating member 63, and the moving member 64 drives the support frame 51 to perform a linear up and down movement relative to the adjustment slot hole 611 based on the rotation of the adjustment rod 62.
