Description

Technical Field

[0001] The utility model relates to the technical field of laser processing auxiliary positioning, and more specifically, to a laser processing auxiliary positioning device. Background Art

[0002] Laser processing, also known as laser processing, is a process that uses a high-energy density light beam to irradiate the surface of a material to vaporize the material or change its color. The most common laser processing equipment is a laser marking machine, which is often used for laser processing of metal parts of printers, copiers and other products. In order to ensure the accuracy of laser processing of parts of printers, copiers and other products, an auxiliary positioning device needs to be set on the laser marking machine.

[0003] The existing auxiliary positioning devices usually only have a fixing effect on the parts. When both sides of the parts need to be laser processed, after the laser processing of one side of the part is completed, it needs to be disassembled and the other side needs to be fixed and processed again. This makes the operation very cumbersome and inconvenient to continuously complete the laser processing of both sides of the parts, which reduces the performance of the device. In view of this, we propose a laser processing auxiliary positioning device. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a laser processing auxiliary positioning device to solve the technical problem that the current laser processing auxiliary positioning device is not convenient for continuously completing the laser processing operation on both sides of the parts.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a laser processing auxiliary positioning device, comprising a placement frame, a rotating frame is rotatably installed on the top of the placement frame, mounting rods are arranged on the front and rear sides of the rotating frame, and two groups of clamping plates are slidably arranged between the two groups of rotating frames;

[0006] Clamping grooves are provided on opposite sides of the two groups of clamping plates, and a plurality of groups of limiting blocks are arranged inside the clamping grooves through springs, and the limiting blocks are distributed side by side.

[0007] When the utility model performs laser processing on parts of printers, copiers, etc., the parts can be clamped and fixed by two sets of clamping plates inside the rotating frame. After the laser processing of one side of the part is completed, the rotating frame can be used to drive the part to rotate 180 degrees and flip the other side upward. At this time, the other side of the part can continue to be laser processed. There is no need to repeatedly disassemble and assemble the parts, so continuous laser processing can be achieved on both sides of the parts, which greatly improves the convenience of using the device. When the part is circular, the limit block that touches the circular edge is subjected to the action force, and the corresponding spring will be compressed at this time. Then the limit blocks at different positions will be displaced to different degrees, so as to combine to form a circular contour that conforms to the part, thereby limiting the part to prevent it from displacing forwards and backwards in the clamping plate, thereby ensuring the stability of the circular part clamping.

[0008] Preferably, the placement rack comprises a bottom plate, four corners of the top of the bottom plate are provided with support rods, and a mounting frame is provided on the top of the support rods.

[0009] Preferably, a rotating shaft is rotatably arranged at the center of both sides of the installation frame through a bearing, and the rotating shaft is connected and fixed to the rotating frame.

[0010] Preferably, one group of the rotating shafts passes through one end of the mounting frame and is provided with a handle, and another group of the rotating shafts passes through one end of the mounting frame and is provided with a positioning structure.

[0011] Preferably, the positioning structure includes a concave frame and a positioning cylinder, the positioning cylinder is arranged on the rotating shaft, a positioning circular hole is opened on the positioning cylinder, the concave frame is arranged on the mounting frame, and the concave frame and the positioning cylinder are arranged symmetrically, a positioning pin is inserted into the top of the concave frame, and the positioning pin and the positioning circular hole are arranged symmetrically.

[0012] Preferably, rectangular through holes are formed at two ends of one side of the clamping plate, and the mounting rod passes through the rectangular through holes.

[0013] Preferably, fixing screw holes are provided at both ends of the top of the clamping plate, and the fixing screw holes are communicated with the rectangular through holes, and fixing bolts are screwed into the fixing screw holes.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model is designed to rotate a rotating frame and a clamping plate and other structures on a placement rack. When laser processing is performed on parts of printers, copiers, etc., the parts can be clamped and fixed by two sets of clamping plates inside the rotating frame. After the laser processing of one side of the part is completed, the rotating frame can be used to drive the part to rotate 180 degrees and flip the other side upward. At this time, the other side of the part can continue to be laser processed. There is no need to repeatedly disassemble and assemble the parts, and continuous laser processing can be achieved on both sides of the parts, which greatly improves the convenience of using the device and solves the technical problem that the current laser processing auxiliary positioning device is not convenient for continuously completing the laser processing of the two sides of the parts. Therefore, the utility model has the advantages of being easy and quick to use.

[0016] 2. The utility model also arranges several groups of springs and limit blocks side by side in the clamping plate. Therefore, when the component is circular, the limit block that touches the circular edge is subjected to force, and the corresponding spring will be compressed. Then the limit blocks at different positions will be displaced to different degrees, thereby combining to form a circular contour that conforms to the component, thereby limiting the component to prevent it from moving forward and backward in the clamping plate, thereby ensuring the stability of the clamping of the circular component.

When laser processing positioning is performed on parts of printers, copiers, etc., the parts are directly placed in the rotating frame 3, and then the two groups of clamping plates 6 are slid to clamp and fix the parts, and then the laser marking machine can perform laser processing on the parts. After the laser processing of this side of the parts is completed, the rotating frame 3 can be rotated 180 degrees, and the ground of the parts in the rotating frame 3 can be turned up, and the other side of the parts can be quickly laser processed. There is no need to repeatedly disassemble and assemble the parts, and continuous laser processing of both sides of the parts can be achieved, which greatly improves the convenience of using the device.

[0024] Specifically, the placement rack 1 includes a bottom plate 101, four corners of the top of the bottom plate 101 are arranged with support rods 102, a mounting frame 103 is arranged on the top of the support rods 102, and sufficient space is reserved between the bottom plate 101 and the mounting frame 103 to ensure that the rotating frame 3 can rotate normally.

[0025] Furthermore, a rotating shaft 2 is rotatably arranged at the center of both sides of the installation frame 103 through bearings. The rotating shaft 2 is connected and fixed to the rotating frame 3. With the cooperation of the rotating shaft 2, the rotating frame 3 is rotatably installed.

[0026] Furthermore, one end of one set of rotating shafts 2 passing through the installation frame 103 is provided with a handle 4, which facilitates people to hold and rotate the rotating frame 3, and another end of the other set of rotating shafts 2 passing through the installation frame 103 is provided with a positioning structure 5, which is used to fix the rotating frame 3.

[0027] It is worth noting that the positioning structure 5 includes a concave frame 501 and a positioning cylinder 503. The positioning cylinder 503 is arranged on the rotating shaft 2. A positioning circular hole 504 is opened on the positioning cylinder 503. The concave frame 501 is arranged on the mounting frame 103, and the concave frame 501 and the positioning cylinder 503 are arranged symmetrically. A positioning pin 502 is inserted into the top of the concave frame 501, and the positioning pin 502 and the positioning circular hole 504 are arranged symmetrically. When the rotating frame 3 rotates 180 degrees, the positioning pin 502 on the concave frame 501 can be directly passed through the positioning circular hole 504 of the positioning cylinder 503, and the rotating frame 3 can be fixed at this time.

[0028] It is worth mentioning that rectangular through holes 604 are opened at both ends of one side of the clamping plate 6 , and the mounting rod 301 passes through the rectangular through holes 604 . The clamping plate 6 can slide on the mounting rod 301 through the rectangular through holes 604 .

[0029] It is worth mentioning that fixing screw holes 605 are opened at both ends of the top of the clamping plate 6, and the fixing screw holes 605 are connected to the rectangular through hole 604. Fixing bolts 606 are screwed into the fixing screw holes 605. When the clamping plate 6 is displaced, the fixing bolts 606 can be screwed to press against the mounting rod 301, thereby fixing the clamping plate 6.

[0030] In an embodiment of the utility model, clamping grooves 601 are opened on opposite sides of the two groups of clamping plates 6, and a plurality of groups of limit blocks 603 are arranged inside the clamping grooves 601 through springs 602, and the limit blocks 603 are distributed side by side. When the component is circular, the limit blocks 603 that touch the circular edges are subjected to force. At this time, the corresponding springs 602 will be compressed, and then the limit blocks 603 at different positions will be displaced to different degrees, thereby combining to form a circular contour that conforms to the component, thereby limiting the component to prevent it from moving forward and backward in the clamping grooves 601 of the clamping plates 6, thereby ensuring the stability of the clamping of the circular component.

[0031] Working principle: This embodiment provides a laser processing auxiliary positioning device. When in use, when laser processing and positioning are performed on parts of printers, copiers, etc., the parts are directly placed in the rotating frame 3, and then two sets of clamping plates 6 are slid to clamp and fix the parts, and then the laser marking machine can perform laser processing on the parts. When the laser processing of this side of the parts is completed, the positioning pin 502 can be removed, and then the handle 4 is held to rotate the rotating frame 3 180 degrees, and the parts in the rotating frame 3 are turned upside down, and the positioning pin 502 is passed through the positioning circular hole 504 again. At this time, the rotating frame 3 can be fixed, and the other side of the parts can be quickly laser processed. There is no need to repeatedly disassemble and assemble the parts, and continuous laser processing can be achieved on both sides of the parts, which greatly improves the convenience of using the device.

[0032] Secondly, when the component is circular, the limit block 603 that touches the circular edge is subjected to force, and the corresponding spring 602 will be compressed. Then the limit blocks 603 at different positions will be displaced to different degrees, thereby combining to form a circular contour that conforms to the component, thereby limiting the component and preventing it from moving forward and backward in the clamping groove 601 of the clamping plate 6, thereby ensuring the stability of clamping the circular component.
