Description

Technical Field

[0001] This utility model relates to marking fixtures, and particularly to marking fixtures, belonging to the field of tooling labeling technology. Background Technology

[0002] Marking fixtures are specialized process equipment used to engrave markings (such as characters, patterns, QR codes, serial numbers, etc.) on the surface of workpieces. They are widely used in machinery manufacturing, electronics, automotive, aerospace and other fields. Their core function is to achieve precise positioning, efficient processing and quality control of markings through mechanical, laser, electrochemical and other technologies, meeting the needs of product traceability, anti-counterfeiting, and aesthetics.

[0003] Publication No. CN220921299U discloses a marking fixture for a laser marking machine, comprising: a fixed frame and a laser marking mechanism disposed on the top of the fixed frame, and a rotating shaft disposed inside the fixed frame; the rotating shaft is located at one end of a worktable on the top of the fixed frame, the worktable being cross-shaped, the laser head of the laser marking mechanism being located on the top of the worktable, and a gear being disposed on the side of the rotating shaft inside the fixed frame; by setting the worktable to a cross shape, the fixture can clamp and laser mark multiple workpieces. Through the cooperation of the rotating groove, rotating rod, teeth, return spring, connecting plate, and arc-shaped sliding groove with the gear, the worktable can be driven to achieve the effect of picking up workpieces. Thus, after multiple workpieces to be marked are pre-clamped and fixed on the top of the worktable, laser marking can be performed continuously without repeatedly starting and stopping the equipment, making the operation simple and quick, thereby improving work efficiency.

[0004] However, in actual use, this type of tooling requires placing the workpiece on the tooling and manually rotating the threaded screw to center and clamp the workpiece. The positioning process is slow and labor-intensive. During marking, the worktable also needs to be rotated manually to ensure that the workpieces stop in sequence under the marking machine. It cannot complete the automated marking work. At the same time, the positioning accuracy of this device is low. During the marking process, manual observation is required to ensure the labeling position, which makes it difficult to ensure the accuracy of the labeling and affects the marking quality.

[0005] Therefore, a marking tooling solution was proposed. Utility Model Content

[0034] like Figure 1-9 As shown, this embodiment of the utility model provides a marking fixture, including...

[0035] Main structure; the main structure includes main frame 1, positioning frame 2, and support plate 11;

[0036] Positioning mechanism; The positioning mechanism includes a frame plate 3, a cylinder A4, a connecting plate A5, a connecting plate B6, a fixing plate 7, a connecting block 8, a pressure block A9, a position detector A10, a hydraulic rod A12, a connecting shaft 13, a pressure block B14, a position detector B15, an L-shaped plate 29, and a laser detector 30.

[0037] Labeling mechanism; The labeling mechanism includes Y-axis slide rail 16, groove block A17, top plate 18, extension plate 19, hydraulic rod B20, X-axis slide rail 21, groove block B22, cylinder B23, side plate 24, marking machine 25, vision detector 26, position detector C27, cover plate 28, and position detector D31.

[0038] Physical error-proofing mechanism; the physical error-proofing mechanism includes cylinder C32 and support plate 33.

[0039] In one embodiment, the positioning frame 2 is installed on the lower right side above the main frame 1, the support plate 11 is also installed on the upper right side of the main frame 1, the frame plate 3 is installed above the main frame 1, the cylinder A4 is hinged in the frame plate 3, the connecting plate A5 and the connecting plate B6 are hinged at the output end of the cylinder A4, the fixing plate 7 is installed in the frame plate 3, the connecting plate B6 is hinged to the fixing plate 7, the connecting block 8 is hinged in the fixing plate 7, the connecting block 8 is hinged to the connecting plate A5, the pressure block A9 is installed on the connecting block 8, the position detector A10 is set in the pressure block A9, the hydraulic rod A12 is hinged above the main frame 1 through a rotating shaft, the connecting shaft 13 is installed on the side of the support plate 11, the pressure block B14 is rotatably installed on the connecting shaft 13, the position detector B15 is installed on the pressure block B14, the L-shaped plate 29 is installed on the main frame 1, the laser detector 30 is installed in the L-shaped plate 29, and the position detector D31 is installed in the support plate 11.

[0040] In one embodiment, the Y-axis slide rail 16 is mounted on the support plate 11, the slot block A17 is slidably mounted on the Y-axis slide rail 16, the top plate 18 is mounted above the slot block A17, the extension plate 19 is mounted behind the top plate 18, the hydraulic rod B20 is hinged above the main frame 1 via a rotating shaft, the X-axis slide rail 21 is mounted on the top plate 18, the slot block B22 is slidably mounted on the X-axis slide rail 21, the cylinder B23 is mounted on the top plate 18, the side plate 24 is mounted on the side of the slot block B22, the marking machine 25 is mounted on the side of the side plate 24, the cover plate 28 is mounted on the top plate 18, the vision detector 26 is mounted inside the cover plate 28, and the position detector C27 is mounted on the back of the marking machine 25.

[0041] In one embodiment, the output end of the hydraulic rod A12 is hinged to the side of the pressure block B14 via a rotating shaft. When the hydraulic rod A12 is activated, it causes the internal piston rod to retract. At this time, under the mechanical coupling between the hydraulic rod A12 and the pressure block B14 and the main frame 1, the pressure block B14 will be driven to adjust its angle along the connecting shaft 13.

[0042] In one embodiment, the output end of the hydraulic rod B20 is hinged to the bottom of the extension plate 19 via a pivot, and the slot block B22 is connected to the output end of the cylinder B23. Activating the hydraulic rod B20 retracts the internal piston rod. Under the mechanical coupling between the hydraulic rod B20 and the main frame 1 and the extension plate 19, the top plate 18 and the slot block A17 slide forward along the Y-axis slide rail 16.

[0043] In one embodiment, there are two sets of groove block B22, side plate 24, and marking machine 25, which are arranged opposite each other on the upper part of the top plate 18. By controlling the two sets of cylinders B23, the marking machine 25 and groove block B22 on both sides are driven to slide along the X-axis slide rail 21, so that the spacing of the marking machine 25 can be flexibly adjusted according to the workpiece size.

[0044] In one embodiment, cylinder C32 is mounted on top plate 18, and support plate 33 is mounted on support plate 11. The first step of the marking operation is platform forward movement, and the second step is the extension of the marking head of the marking machine 25. The sequence of these two actions is fixed. If the sequence of steps is reversed, cylinder C32 will drive the internal piston rod to extend. When the platform forward movement is performed after the marking head of the marking machine 25 has extended, the piston rod of cylinder C32 interferes with the support plate 33, blocking the platform's forward movement and thus protecting the marking head of the marking machine 25 from collision.

[0045] In operation, this invention works as follows: First, the workpiece is placed on the customized positioning frame 2. Then, the workpiece is detected by the laser detector 30, and its position is adjusted to ensure it is in place. Next, the cylinder A4 is activated, causing the internal piston to extend. At this time, under the mechanical coupling of the connecting plate A5, connecting plate B6, and connecting block 8, the connecting block 8 and the pressure block A9 are adjusted in angle within the fixed plate 7, thereby causing the pressure block A9 to press against the surface of the workpiece. The position detector A10 detects whether the workpiece is in place. Simultaneously, the hydraulic rod A12 is activated, causing the internal piston rod to retract. At this time, under the mechanical coupling between the pressure block B14 and the main frame 1, the pressure block B14 is adjusted in angle along the connecting shaft 13, causing the pressure block B14 to press against the other side of the workpiece. The position detector also detects this. The device B15 performs position detection, then activates the hydraulic rod B20 and drives the internal piston rod to retract. Under the mechanical coupling between the hydraulic rod B20 and the main frame 1 and the extension plate 19, the top plate 18 and the groove block A17 will slide forward along the Y-axis slide rail 16, which will in turn drive the two sets of marking machines 25 above to move forward. By controlling the two sets of cylinders B23, the marking machines 25 and the groove block B22 on both sides will slide along the X-axis slide rail 21. Thus, the spacing of the marking machines 25 can be flexibly adjusted according to the workpiece size to ensure the accuracy of the position. After the marking machine 25 moves above the marking position, the marking work can be carried out. During this process, the vision detector 26 will monitor the marking process to ensure the normal operation of the marking work and avoid the occurrence of missing labels due to label detachment.

[0046] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
