Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving processing, in particular to a fixed base for a laser engraving jig. Background Art

[0002] Laser engraving, also known as laser carving, is a process of locally removing the surface of a material using a laser beam with a high energy density to achieve an engraving effect. It has the characteristics of non-contact processing, high precision, wide application range, and fast processing speed. With the advent of the information age, existing communication devices are constantly evolving. For consumer electronics such as smart electronic devices, their appearance effect is very important and has a great impact on product sales, making laser engraving technology widely used in various industries such as electronics and automotive.

[0003] Before a laser engraving machine engraves a workpiece, a laser engraving positioning jig is required to position and place the workpiece to ensure the accuracy of the position where the workpiece is laser engraved. Then, the laser engraving positioning jig is installed on the base of the laser engraving machine. Subsequently, the parameters of the laser engraving machine are adjusted. After the parameters are adjusted, the laser head of the laser engraving machine starts to engrave the workpiece.

[0004] Currently, for the laser engraving jig and the base on the laser engraving machine table, they are generally fixed and connected by glue or bolts. However, since the laser engraving jig needs to be frequently taken out for adjustment or replacement, the following defects exist in the fixing method of the existing laser engraving jig and the machine table base:

[0005] 1. When the laser engraving jig and the machine table base are fixed with glue, it will occur that when the laser engraving jig is taken out and used again, it cannot be accurately fixed to the original position, resulting in the need for staff to readjust the laser engraving parameters, increasing the machine adjustment time and affecting work efficiency;

[0006] 2. When the laser engraving jig and the machine table base are fixed with bolts, although the fixing effect and the position accuracy effect are guaranteed, there will be trouble in disassembling the laser engraving jig, and the bolts will also become stripped when subjected to frequent screwing, resulting in affecting the fixing effect of the laser engraving jig and posing a hidden danger of position deviation of the laser engraving jig during the laser engraving process.

[0007] In summary, there are obvious defects in the fixing method of the laser engraving jig and the machine table base in the prior art, which urgently need to be improved.

[0008] Therefore, it is necessary to propose a new technical solution to solve the above problems. Content of the Utility Model

[0009] The utility model aims to provide a technical solution that can solve the defects of the existing fixing method of the laser engraving jig and the base to overcome the above situation.

[0010] To achieve the above object, the present utility model provides the following technical solution: A fixing base for a laser engraving jig, including the laser engraving jig and a base for fixedly placing the laser engraving jig;

[0011] On at least two sides of the side of the base facing the laser engraving jig, there are provided positioning posts, and on the side of the laser engraving jig facing the base, there are provided positioning holes corresponding to the positions of the positioning posts, and the positioning posts can be inserted and matched with the positioning holes.

[0012] As a further solution of the present utility model: Blind holes are provided at both ends of the base, and on both sides of the base near the blind holes, there are provided clamping mechanisms. The clamping mechanisms include telescopic rods fixedly arranged inside the blind holes. On the opposite ends of the two telescopic rods, there are fixed blocks. A spring is arranged between the telescopic rods and the fixed blocks. On the side of the fixed block near the base, there is an insertion end, and on the side of the insertion end away from the base, there is a clamping block;

[0013] On both sides of the lower end of the laser engraving jig, there are provided insertion grooves corresponding to the insertion ends, and in the insertion grooves, there are provided card slots corresponding to the clamping blocks;

[0014] Wherein, the width of the insertion groove is greater than or equal to the sum of the widths of the insertion end and the clamping block.

[0015] As a further solution of the present utility model: Notches are formed at both ends of the base, and the positions where the blind holes are opened and the positions of the clamping mechanisms are located in the notches.

[0016] As a further solution of the present utility model: On one side of the top ends of both the clamping block and the card slot, they are both inclined surfaces, and on one side of the lower end edge of the insertion groove, there is formed a guiding inclined surface corresponding to the top inclined surface of the clamping block.

[0017] As a further solution of the present utility model: On the side of the fixed block away from the base and near the bottom position, there is provided a lower pressing plate.

[0018] As a further solution of the present utility model: Fixing holes are provided at the four corners of the base, and installation bolts are arranged in the fixing holes.

[0019] Compared with the prior art, the beneficial effects of the present technical solution are as follows: When placing the laser engraving jig, the four positioning holes of the laser engraving jig are inserted and matched with the positioning posts on the base, so that the laser engraving jig is fixedly placed on the base. By setting the four positioning posts, when the laser engraving jig needs to be placed on the base again after being taken out, it can ensure that the position is the original position, and the installation is rapid, without the need to frequently adjust the laser engraving parameters, reducing the adjustment time and improving the laser engraving efficiency;

[0020] By the mutual abutment of the guiding inclined surface and the top inclined surface of the clamping block, as the laser engraving jig continues to be lowered, the insertion end and the clamping block gradually enter the insertion groove. After entering the insertion groove, the fixing block is pushed outward and reset by the spring, so that the clamping block is engaged with the clamping groove, thereby fixing the laser engraving jig, and the position of the laser engraving jig can be further fixed to prevent the laser engraving jig from shaking up and down;

[0021] When it is necessary to disassemble the laser engraving jig from the base, the staff can push the fixing block towards the middle of the base while holding the laser engraving jig, so that the fixing block drives the insertion end and the clamping block to move, thereby separating the clamping block from the clamping groove. Then, keep the position with both hands and lift the laser engraving jig upward to disassemble the laser engraving jig from the base.

[0022] The additional aspects and advantages of the present utility model will be partly given in the following description, partly will become obvious from the following description, or will be understood through the practice of the present utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] Please refer to Figures 1-4 , a fixing base for a laser engraving jig, including a laser engraving jig 1 and a base 2 for fixedly placing the laser engraving jig 1;

[0035] On at least two sides of the base 2 facing the laser engraving jig 1, there are positioning posts 3. On the side of the laser engraving jig 1 facing the base 2, there are positioning holes 11 that can correspond to the positions of the positioning posts 3, and the positioning posts 3 can be inserted and matched with the positioning holes 11.

[0036] Specifically, the numbers of both the positioning posts 3 and the positioning holes 11 are four. When placing the laser engraving jig 1, insert the four positioning holes 11 of the laser engraving jig 1 into the positioning posts 3 on the base 2, so as to fixedly place the laser engraving jig 1 on the base 2. With the arrangement of the four positioning posts 3, when the laser engraving jig 1 is taken out and then needs to be placed on the base 2 again, it can ensure that the position is the original position, and the installation is rapid, without the need to frequently adjust the laser parameters, reducing the adjustment time and improving the laser engraving efficiency.

[0037] Preferably, fixing holes 21 are provided at the four corners of the base 2, and installation bolts 4 are provided in the fixing holes 21;

[0038] By providing the fixing holes 21 on the base 2, the base can be fixedly installed on the laser engraving machine table by using the installation bolts 4, avoiding the laser engraving position error caused by the movement of the base 2.

[0039] More preferably, notches 22 are formed at both side ends of the base 2. When removing the laser engraving fixture 1 from the base 2, the staff can reach into the notches 22 with both hands and lift the laser engraving fixture 1 upward from the bottom of the laser engraving fixture 1, reserving space for the hands of the staff and facilitating the disassembly of the laser engraving fixture 1.

[0040] In the embodiment of the present utility model, blind holes 23 are provided at both side ends of the base 2, and clamping mechanisms 5 are arranged on both sides of the base 2 close to the blind holes 23. The clamping mechanism 5 includes a telescopic rod 51 fixed inside the blind hole 23. On the opposite side ends of the two telescopic rods 51, a fixed block 52 is fixedly connected. A spring 55 is arranged between the telescopic rod 51 and the fixed block 52. On the side of the fixed block 52 close to the base 2, an insertion end 53 is provided. On the side of the insertion end 53 away from the base 2, a clamping block 54 is provided. The telescopic rod 51 is composed of a fixed part and a telescopic part. The fixed part is fixedly installed in the blind hole 23, and one end of the telescopic part is movably arranged inside the oral cavity of the fixed part, and the other end extends outward to be connected with the fixed block 52. The spring 55 is located between the fixed part and the fixed block 52;

[0041] Insertion slots 12 corresponding to the insertion ends 53 are provided at both side ends of the lower end of the laser engraving fixture 1, and clamping slots 13 corresponding to the clamping blocks 54 are provided in the insertion slots 12;

[0042] Among them, the width of the insertion slot 12 is greater than or equal to the sum of the widths of the insertion end 53 and the clamping block 54, so that the insertion end 53 and the clamping block 54 can enter the insertion slot 12.

[0043] Specifically, during the process of placing the laser engraving fixture 1 on the base 2, the staff can simultaneously push the fixed block 52 towards the middle of the base 2 with both hands, align the positions of the insertion end 53 and the clamping block 54 with the insertion slot 12, and then release the hand pushing the fixed block 52 after putting down the laser engraving fixture 1. At this time, the spring 55 is used to push the fixed block 52 outward to reset, so that the insertion end 53 and the clamping block 54 move in the insertion slot 12, and further the clamping block 54 is engaged with the clamping slot 13, thereby fixing the laser engraving fixture 1, and further fixing the position of the laser engraving fixture 1 to prevent the laser engraving fixture 1 from shaking up and down;

[0044] When it is necessary to disassemble the laser engraving fixture 1 from the base 2, the staff can push the fixed block 52 towards the middle of the base 2 while holding the laser engraving fixture 1, so that the fixed block 52 drives the insertion end 53 and the clamping block 54 to move, and further the clamping block 54 is separated from the clamping slot 13. Then, keep the position with both hands and lift the laser engraving fixture 1 upward, and the laser engraving fixture 1 can be disassembled from the base 2.

[0045] Preferably, the position where the blind hole 23 is opened and the position of the clamping mechanism 5 are located in the notch 22; by opening the blind hole 23 on both side surfaces of the notch 22 on both sides of the base 2, the clamping mechanism 5 can be arranged in the notch 22, which is more convenient for the staff to carry out the disassembly operation.

[0046] Furthermore, one side of the top ends of the clamping block 54 and the clamping groove 13 are both arranged in an inclined surface, and a guiding inclined surface 14 corresponding to the inclined surface at the top end of the clamping block 54 is formed at the edge of one side at the lower end of the insertion groove 12.

[0047] Specifically, during the process of lowering the laser engraving jig 1 towards the base 2, by the mutual abutment of the guiding inclined surface 14 and the inclined surface at the top end of the clamping block 54, as the laser engraving jig 1 continues to be lowered, the insertion end 53 and the clamping block 54 gradually enter the inside of the insertion groove 12, and after entering the insertion groove 12, the clamping block 54 is clamped and matched with the clamping groove 13 through the spring 55, so that it is not necessary for the staff to manually push the fixing block 52 during the process of placing the laser engraving jig 1, making the installation of the laser engraving jig 1 more convenient.

[0048] Even further, a lower abutting plate 56 is arranged at a position near the bottom on the side of the fixing block 52 away from the base 2.

[0049] Specifically, during the process of disassembling the laser engraving jig 1, when the staff pushes the fixing block 52, the bottom of the hand can lean against the lower abutting plate 56, which is convenient for the staff to accurately push the fixing block 52 in a state without vision and makes the pushing more convenient.
