Description

Technical Field

[0001] This utility model belongs to the technical field of cutting protection devices, and in particular relates to a product protection device for laser-weakening OK cut fixtures. Background Technology

[0002] When laser pulses are used to perform a drilling and weakening process on the workpiece, the drilling follows a preset trajectory. An OK cut is typically pre-made on the workpiece; the OK cut and the workpiece are integrally injection molded. The OK cut serves as a marker to prevent errors, removing redundant parts of the product design.

[0003] OK cut is a defect prevention marker that needs to be removed after processing. When existing laser pulses perform OK cuts on the workpiece, if there is still a part of the product in the cut-off optical path, it will suffer unacceptable damage. Therefore, this utility model proposes a product protection device for laser weakening die OK cuts to solve the above problems. Utility Model Content

[0004] This invention provides a product protection device for laser-weakened OK cuts on jigs, aiming to solve the problems mentioned in the background art.

[0005] This utility model is implemented as follows: a product protection device for laser-weakened OK cut fixtures, including a rotary self-locking cylinder.

[0006] The output end of the rotary self-locking cylinder is connected to the main connecting rod, and the main connecting rod is connected to the secondary connecting rod. The secondary connecting rod is provided with two support rods, one of which is provided with a clamping plug, and the other of which is provided with a protective baffle.

[0007] The clamping plug is used to clamp the part to be processed, and the protective baffle is used to block the laser pulse from directly hitting the body of the part to be processed;

[0008] The part to be processed is equipped with an OK cutter, which is removed by laser pulse.

[0009] Preferably, the clamping plug is connected to the secondary connecting rod by a fastening bolt.

[0010] Preferably, the protective baffle is connected to the secondary connecting rod by bolts.

[0011] Preferably, the rotary self-locking cylinder drives the main connecting rod and the auxiliary connecting rod to rotate.

[0012] Preferably, the two supports on the secondary connecting rod bypass the OK cut on the part to be processed.

[0013] Preferably, when the rotary self-locking cylinder rotates and drives the clamping plug to press the workpiece to be processed, the protective baffle will block the front of the workpiece body and be located behind the OK cut, so that the laser pulse can cut the OK cut without damaging the workpiece body.

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

[0015] The workpiece to be processed is mounted on a support device, and a rotary self-locking cylinder is also mounted on the support device. A laser pulse is positioned in front of the support device. First, the workpiece to be processed is mounted on the support device, and then the rotary self-locking cylinder is started to rotate. The rotation of the rotary self-locking cylinder drives the main connecting rod and the auxiliary connecting rod to rotate and press the workpiece to be processed. At this time, the clamping plug presses the workpiece to be processed onto the support device, while the protective baffle is located in front of the workpiece to be processed and after the OK cut. Then, the laser pulse is started to cut the OK cut. Since the protective baffle is located in front of the workpiece to be processed and after the OK cut, the laser beam of the laser pulse can pass through the OK cut but cannot pass through the protective baffle, thus the protective baffle achieves the purpose of protecting the workpiece to be processed.

[0029] Please see Figures 1 to 6 This utility model provides a technical solution: a product protection device for laser-weakened OK cut on a fixture, comprising a rotary self-locking cylinder 1; the output end of the rotary self-locking cylinder 1 is connected to a main connecting rod 2, the main connecting rod 2 is connected to a secondary connecting rod 3, the secondary connecting rod 3 is provided with two support rods, one of which is provided with a clamping plug 4, and the other is provided with a protective baffle 6; the clamping plug 4 is used to clamp the workpiece 7 to be processed, and the protective baffle 6 is used to block the laser pulse 9 from directly hitting the workpiece 7 to be processed; the workpiece 7 to be processed is provided with an OK cut 8, which is removed by the laser pulse 9.

[0030] In this embodiment, the part to be processed 7 is mounted on the support device, the rotary self-locking cylinder 1 is also mounted on the support device, and the laser pulse 9 is located in front of the support device; firstly, the part to be processed 7 is mounted on the support device (as shown in the attached figure). Figure 2 and attached Figure 5 (As shown in the attached diagram), and then the rotary self-locking cylinder 1 is started to rotate. The rotation of the rotary self-locking cylinder 1 drives the main connecting rod 2 and the auxiliary connecting rod 3 to rotate and press the workpiece 7 to be processed. At this time, the clamping plug 4 presses the workpiece 7 to be processed onto the support device, while the protective baffle 6 is located in front of the main body of the workpiece 7 and after the OK cut 8 (the state is as shown in the attached diagram). Figure 3 and attached Figure 6 As shown), then the laser pulse 9 is activated to cut off the OK cut 8. Since the protective baffle 6 is located in front of the main body of the part to be processed 7 and after the OK cut 8, the laser beam of the laser pulse 9 can pass through the OK cut 8 but cannot pass through the protective baffle 6, so the protective baffle 6 achieves the purpose of protecting the main body of the part to be processed 7.

[0031] Among them, the protective baffle 6 can be made of carbon plate; the distance between this protective position and the OK cut 8 is greater than 5mm (the space required for smoke dissipation and heat dissipation in laser processing), and greater than 3mm (the safety distance for anti-collision) is required; the rotation angle of the self-locking cylinder 1 that drives the main connecting rod 2 and the auxiliary connecting rod 3 to rotate is such that it can bypass the OK cut 8 and does not interfere with it during rotation; the path of the self-locking cylinder 1 that drives the main connecting rod 2 and the auxiliary connecting rod 3 to rotate is a semi-circular arc path.

[0032] For further details, please refer to Figure 1 The compression plug 4 is connected to the auxiliary connecting rod 3 by the fastening bolt 5.

[0033] In this embodiment, the clamping plug 4 is connected to the secondary connecting rod 3 by the fastening bolt 5, which prevents the clamping plug 4 from falling off the secondary connecting rod 3 and avoids affecting the clamping effect.

[0034] For further details, please refer to Figure 1 The protective baffle 6 is connected to the auxiliary connecting rod 3 by bolts.

[0035] In this embodiment, the protective baffle 6 is connected to the secondary connecting rod 3 by bolts, which prevents the protective baffle 6 from falling off the secondary connecting rod 3 and avoids affecting the shielding effect.

[0036] For further details, please refer to Figure 2 and Figure 3 The rotating self-locking cylinder 1 drives the main connecting rod 2 and the auxiliary connecting rod 3 to rotate.

[0037] For further details, please refer to Figures 1 to 6When the self-locking cylinder 1 rotates and drives the clamping plug 4 to clamp the workpiece 7 to be processed, the protective baffle 6 will block the front of the workpiece 7 and the back of the OK cut 8. In this way, the laser pulse 9 can cut the OK cut 8 without damaging the workpiece 7.

[0038] In this embodiment, the rotary self-locking cylinder 1 is activated to rotate. The rotation of the rotary self-locking cylinder 1 drives the main connecting rod 2 and the auxiliary connecting rod 3 to rotate and press the workpiece 7 to be processed. At this time, the clamping plug 4 presses the workpiece 7 to be processed onto the support device, while the protective baffle 6 is located in front of the main body of the workpiece 7 and after the OK cut 8 (the state is as shown in the attached figure). Figure 3 and attached Figure 6 As shown), then the laser pulse 9 is activated to cut off the OK cut 8. Since the protective baffle 6 is located in front of the main body of the part to be processed 7 and after the OK cut 8, the laser beam of the laser pulse 9 can pass through the OK cut 8 but cannot pass through the protective baffle 6, thereby protecting the baffle 6 to protect the main body of the part to be processed 7.

[0039] For further details, please refer to Figures 1 to 3 The two support rods on the secondary connecting rod 3 bypass the OK cutter 8 on the part to be processed 7.

[0040] In this embodiment, the rotation of the self-locking cylinder 1 drives the main connecting rod 2 and the auxiliary connecting rod 3 to rotate at an angle that can bypass the OK cut 8 and avoid interference during the rotation process.

[0041] The working principle and usage process of this utility model are as follows: The part to be processed 7 is installed on the support device, the rotary self-locking cylinder 1 is also installed on the support device, and the laser pulse 9 is located in front of the support device; first, the part to be processed 7 is installed on the support device (as shown in the attached figure). Figure 2 and attached Figure 5 (As shown in the attached diagram), and then the rotary self-locking cylinder 1 is started to rotate. The rotation of the rotary self-locking cylinder 1 drives the main connecting rod 2 and the auxiliary connecting rod 3 to rotate and press the workpiece 7 to be processed. At this time, the clamping plug 4 presses the workpiece 7 to be processed onto the support device, while the protective baffle 6 is located in front of the main body of the workpiece 7 and after the OK cut 8 (the state is as shown in the attached diagram). Figure 3 and attached Figure 6 As shown), then the laser pulse 9 is activated to cut off the OK cut 8. Since the protective baffle 6 is located in front of the main body of the part to be processed 7 and after the OK cut 8, the laser beam of the laser pulse 9 can pass through the OK cut 8 but cannot pass through the protective baffle 6, thereby protecting the baffle 6 to protect the main body of the part to be processed 7.
