Description

Technical Field

[0001] This application relates to the field of laser processing technology, and in particular to a laser marking and positioning device. Background Technology

[0002] A laser marking machine is a precision processing device that uses a laser beam to mark the surface of a material. It achieves permanent or semi-permanent marking through the high energy density of the laser. The marking effect is achieved by evaporating the surface material to expose the deeper material, thereby engraving exquisite patterns, trademarks, and text.

[0003] When existing laser marking machines are in operation, the laser marking content is preset in the CNC machine. The workpiece is placed on the positioning platform. Usually, two mutually perpendicular baffles fixed on the positioning platform are used to assist in the positioning of the workpiece, so that the position between the laser marking machine nozzle and the workpiece corresponds.

[0004] Regarding the aforementioned technologies, the inventors believe that existing laser marking machines can quickly position workpieces with relatively regular shapes, but when the workpiece has multiple bevels, the baffle is difficult to use for auxiliary positioning of workpieces with multiple bevels. It is necessary to rely on the operator's experience to adjust and position multiple workpieces with multiple bevels, resulting in low positioning efficiency for workpieces with multiple bevels. Utility Model Content

[0005] The purpose of this application is to provide a laser marking and positioning device to improve the problem of low positioning efficiency for multi-beveled workpieces.

[0006] The laser marking and positioning device provided in this application adopts the following technical solution:

[0007] A laser marking positioning device includes a positioning platform, with up to two positioning plates above the positioning platform and positioning rods below the positioning plates. The positioning platform has positioning holes for the positioning rods to be inserted. A limit block with a through hole is provided above the positioning plates. A positioning screw is provided above the positioning plates, and a positioning nut is provided through the through hole on the positioning screw. The positioning nut can fit against the limit block, and the limit block can rotate circumferentially around the positioning screw. A pad flush with the upper surface of the positioning plates is provided on the positioning platform.

[0008] By adopting the above technical solution, when a workpiece has two or more inclined surfaces, two mutually perpendicular positioning plates can be set next to it. By adjusting the limiting blocks on the positioning plates, they can be made to fit tightly against the adjacent inclined sides of the workpiece. Then, the limiting blocks are fixed, thereby achieving the purpose of assisting the workpiece in rapid positioning and improving the problem of low positioning efficiency for workpieces with multiple inclined surfaces.

[0009] Optionally, the limiting block is provided with a positioning sleeve, which is fixedly fitted with the through hole, and the inner side wall of the positioning sleeve is in contact with the positioning screw.

[0010] By adopting the above technical solution, the positioning sleeve is embedded and fixed in the through hole, and its smooth inner wall is closely fitted with the outer surface of the positioning screw. The positioning sleeve can reduce the friction between the limiting block and the positioning screw when the limiting block rotates, thereby facilitating the adjustment of the rotation angle of the limiting block.

[0011] Optionally, the limiting block is provided with a receiving groove for placing the positioning nut.

[0012] By adopting the above technical solution, a receiving groove is set on the limiting block so that the positioning nut can be accommodated in the receiving groove. This not only improves the structure of the limiting block but also reduces its weight and facilitates the adjustment of the rotation angle of the limiting block.

[0013] Optionally, an elastic ring is provided at the bottom of the receiving groove, which can abut against the positioning nut.

[0014] By adopting the above technical solution, when the positioning nut presses tightly against the limiting block, the elastic ring forms a buffer contact between the two, which can effectively reduce the direct wear between the limiting block and the positioning nut, and extend the service life while protecting the structure of both.

[0015] Optionally, the bottom of the receiving groove is provided with a retaining groove for the elastic ring to be fitted and secured.

[0016] By adopting the above technical solution, the retaining groove provided on the limiting block can be fitted with the elastic ring to achieve a stable installation of the elastic ring, ensuring its stability during use and effectively reducing the occurrence of the elastic ring detaching from the limiting block.

[0017] Optionally, the positioning holes are provided in a plurality of manner.

[0018] By adopting the above technical solution, multiple positioning holes allow the positioning plate to be installed in multiple positions on the positioning platform, enabling the positioning plate to adjust the position of the limiting block according to the workpiece size, thereby facilitating the fixing of the workpiece by the limiting block.

[0019] Optionally, the positioning nut is provided with an extension plate.

[0020] By adopting the above technical solution, an extension plate is set on the positioning nut, and the worker can directly turn the extension plate to adjust the mating depth with the positioning screw without the need for a torque wrench, thus conveniently adjusting the rotation angle of the limit block.

[0021] Optionally, several friction blocks are provided on both sides of the extension plate.

[0022] By adopting the above technical solution and setting friction blocks on both sides of the extension plate, the friction coefficient between the worker and the extension plate can be effectively increased by increasing the roughness of the contact surface, reducing slippage or slippage during tightening, and enabling the worker to adjust the positioning nut more stably.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When a workpiece has two or more inclined surfaces, two mutually perpendicular positioning plates can be set next to it. By adjusting the limiting blocks on the positioning plates, they can be made to fit tightly against the adjacent inclined sides of the workpiece. Then the limiting blocks are fixed to achieve the purpose of assisting the workpiece in rapid positioning and improve the problem of low positioning efficiency of workpieces with multiple inclined surfaces.

[0025] 2. An extension plate is installed on the positioning nut, allowing workers to directly screw the extension plate to adjust its engagement depth with the positioning screw without the need for a torque wrench, thus conveniently adjusting the rotation angle of the limit block;

[0026] 3. By setting friction blocks on both sides of the extension plate, the friction coefficient between the worker and the extension plate can be effectively increased by increasing the roughness of the contact surface, reducing slippage or slippage during tightening, and allowing the worker to adjust the positioning nut more stably.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail below.

[0032] A laser marking and positioning device, referring to Figure 1 and Figure 2The system includes a horizontal positioning platform 1, with up to two positioning plates 11 on top of the positioning platform 1. The positioning plates 11 are horizontal, and a positioning rod 12 is fixedly installed below the positioning plates 11 by welding. The positioning rod 12 is round. The positioning platform 1 is provided with positioning holes 13 for the positioning rod 12 to be inserted. There are several positioning holes 13. In this embodiment, the number of positioning rods 12 is preferably 3, and the number of positioning holes 13 is preferably 230.

[0033] Reference Figure 1 and Figure 2 A limiting block 2 is provided above the positioning plate 11. The limiting block 2 is in the shape of a long strip and has a through hole 25 in the middle. The through hole 25 is cylindrical. A positioning screw 14 is fixedly provided above the positioning plate 11 by welding. The positioning screw 14 is in the shape of a round rod and the other end of the positioning screw 14 connected to the positioning plate 11 is a threaded end.

[0034] Reference Figure 1 and Figure 2 A positioning nut 15 is provided through the through hole 25 of the positioning screw 14. The positioning nut 15 is threaded to the end of the positioning screw 14 and can fit with the limiting block 2. The limiting block 2 rotates around the positioning screw 14 with the axis of the positioning screw 14 as the center. By adjusting the thread fit depth between the positioning nut 15 and the positioning screw 14, the tightness or looseness between the limiting block 2 and the positioning plate 11 can be controlled.

[0035] Reference Figure 1 The positioning platform 1 is equipped with a pad 16 that is flush with the upper surface of the positioning plate 11. The pad 16 is horizontal. The first workpiece is placed on the pad 16. After the positioning is completed manually, the rotation angle of the two limit blocks 2 is adjusted so that they are in contact with the inclined surface of the workpiece. Subsequent workpieces only need to have their inclined surfaces abut against the limit blocks 2 after the fixed deflection angle to achieve rapid positioning, which effectively improves the problem of low positioning efficiency of multi-sloped workpieces.

[0036] Reference Figure 1 and Figure 2 An extension plate 3 is fixedly installed above the positioning nut 15 by welding. In this embodiment, the extension plate 3 is a vertical long plate. The number of extension plates 3 is preferably 2. The top height of the extension plate 3 exceeds the opening of the receiving groove 22, so that the worker can adjust the matching relationship between the positioning nut 15 and the limiting block 2 by turning the extension plate 3.

[0037] Reference Figure 2 Several friction blocks 31 are fixedly provided on both sides of the extension plate 3 by welding. In this embodiment, the friction blocks 31 are hemispherical in shape, and the number of friction blocks 31 is preferably 6. By increasing the roughness of the contact surface of the extension plate 3, the slippage or slippage phenomenon when turning the positioning nut 15 can be reduced.

[0038] Reference Figure 2 and Figure 3 The limiting block 2 is provided with a receiving groove 22 for placing the positioning nut 15, which improves the structure of the limiting block 2, reduces the weight of the limiting block 2, and facilitates the adjustment of the rotation angle of the limiting block 2. An elastic ring 23 is provided at the bottom of the receiving groove 22. When the mating depth between the positioning nut 15 and the positioning screw 14 is adjusted to achieve the fastening of the limiting block 2 and the positioning plate 11, the positioning nut 15 abuts against the elastic ring 23. In this embodiment, the material of the elastic ring 23 is preferably rubber, and the elastic ring 23 is in the shape of a flat ring.

[0039] Reference Figure 2 and Figure 3 The bottom of the receiving groove 22 is provided with a retaining groove 24 for the elastic ring 23 to be embedded and fixed. By setting the retaining groove 24, the elastic ring 23 is more stably fixed on the limiting block 2, reducing the impact of the thickness of the elastic ring 23 on the tight fit between the positioning nut 15 and the limiting block 2.

[0040] Reference Figure 3 The limiting block 2 is provided with a positioning sleeve 21, which is fixedly fitted with the through hole 25. The inner side wall of the positioning sleeve 21 is in contact with the positioning screw 14, and its smooth inner side wall is in close contact with the outer surface of the positioning screw 14. The positioning sleeve 21 can reduce the friction between the limiting block 2 and the positioning screw 14 when the limiting block 2 rotates, thereby facilitating the adjustment of the rotation angle of the limiting block 2.

[0041] The implementation principle of this application embodiment is as follows:

[0042] When performing laser marking on multi-sloped workpieces, the first workpiece is placed on the pad 16, and the position of the workpiece is manually adjusted. The rotation angle of the two limit blocks 2 is adjusted so that they fit with the inclined surface of the workpiece after positioning, and the deflection angle of the limit blocks 2 is fixed. Subsequent workpieces only need to have their inclined surface abut against the limit blocks 2 to achieve rapid positioning of the workpiece, effectively solving the problem of low positioning efficiency of multi-sloped workpieces.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
