Description

Technical Field

[0001] This utility model belongs to the field of laser marking machine accessories, and in particular, it is a water pump tooling adapted to laser marking machines. Background Technology

[0002] To meet the quality traceability requirements of automotive parts, production batch information needs to be marked on the parts. Current methods for manufacturing batch information include: 1. Hanging paper barcode + laser marking of batch information on the part itself; 2. Inkjet printing on the part itself; 3. Laser marking of QR codes on the part itself.

[0003] Existing methods have the following problems: 1) Hanging paper barcodes is cumbersome: printing, affixing, and hanging barcodes, which are then removed after the customer scans them; 2) Inkjet printing on products: the marking information is easily damaged; 3) Laser marking: generally, batch information can be marked at the same focal point, but to meet the marking requirements at different heights or positions, separate processes or customized non-standard laser marking equipment are needed. Separate processes result in repetitive work, leading to cost waste; customized non-standard equipment requires significant investment.

[0004] For smaller parts, multiple markings on the same product can be achieved through tooling, fixtures, and equipment programming, allowing for one-time processing. Utility Model Content

The base plate has a window, the top plate is fixed to the base plate by multiple columns, and the handles are symmetrically arranged and fixed to the base plate.

[0008] Further defining the above technical solution, the structure of the parts lifting platform includes a cylinder with a stepped outer surface and a positioning groove on the top surface of the cylinder.

[0009] Further defining the above technical solution, the top of the part lifting platform is provided with a movable fixture base plate, the bottom of the fixture base plate is provided with a limiting shaft, the limiting shaft is slidably connected to the positioning groove cavity of the part lifting platform, the fixture base plate is provided with a limiting hole, the limiting hole is provided with a limiting pin, the outer side of the part lifting platform is provided with a pin seat, the limiting pin is slidably connected to the pin hole on the pin seat, and the limiting pin and the pin seat cooperate to limit the rotation of the fixture base plate.

[0015] like Figure 1 As shown, a water pump fixture adapted to a laser marking machine includes a base 1. The support surface of the base is provided with a left guide limiting mechanism 2, a right guide limiting mechanism 3 and a part lifting platform 4. The left guide limiting mechanism and the right guide limiting mechanism are used to guide the lifting of the part lifting platform and limit its height. The base is provided with a lifting cylinder 5, which is used to lift the part lifting platform.

[0016] like Figure 2 As shown, the structure of the base 1 includes a base plate 11, a top plate 12, columns 13, and handles 14. The base plate is provided with a window 15, which facilitates the passage of cylinder lines. The top plate is fixed to the base plate by multiple columns, and the symmetrically arranged handles are fixed to the base plate. This structure is simple, easy to move, and has good stability.

[0017] like Figure 2 and Figure 3As shown, the structure of the left guide limiting mechanism 2 includes a positioning block 21 and a limiting block 22. The positioning block is fixed to the top plate, and the limiting block is fixed to the top of the positioning block. The inner end face of the limiting block is an arc-shaped surface 23. The inner end of the limiting block can engage with the lower end of the part lifting platform for limiting. The inner end face of the limiting block is slidably connected to the outer circular surface of the upper end of the part lifting platform. The advantages of this structure are that it integrates guiding and limiting functions into one unit, which reduces the number of parts and helps to reduce production costs and achieve weight reduction.

[0018] The left guide limiting mechanism 2 and the right guide limiting mechanism 3 have the same structure;

[0019] like Figure 2 As shown, the structure of the lifting platform 4 includes a cylinder 41, the outer diameter of the upper part of the cylinder is smaller than the outer diameter of the lower part, so that the outer surface of the cylinder is stepped. The stepped surface 42 on the cylinder is used for limiting fit, and a positioning groove 43 is provided on the top surface of the cylinder. This structure is simple, has low production cost, strong versatility, and good stability.

[0020] like Figure 1 As shown, the lifting cylinder 5 is fixed to the bottom surface of the top plate, and the working end of the lifting cylinder is fixedly connected to the bottom surface of the lower truncated cone or connected to the hinge seat on the bottom surface of the lower truncated cone through a pin.

[0021] The upper truncated cone of this invention uses its internal positioning groove to position the part to be marked; when other parts cannot be positioned through the positioning groove, a fixture for other parts can be placed on the upper truncated cone. Figure 4 As shown, the top of the part lifting platform 4 is provided with a movable fixture base plate 6, which is used to fix the part fixture. The bottom of the fixture base plate is provided with a limiting shaft 7, which is slidably connected to the positioning groove cavity of the part lifting platform. The fixture base plate is provided with a limiting hole, and a limiting pin 8 is provided in the limiting hole. A pin seat 9 is provided on the outer side of the part lifting platform. The limiting pin is slidably connected to the pin hole on the pin seat. The limiting pin and the pin seat cooperate to limit the rotation of the fixture base plate. This structure is simple, has low production cost, and improves versatility.

[0022] During operation, the part is positioned on the lifting platform via the positioning slot. The laser marking machine is started, and after partial marking is completed on the part, the marking program stops. The equipment's PLC controls the solenoid valve to allow air into the cylinder, lifting the lifting platform. During lifting, the arc-shaped surface of the limit block and the cylinder piston rod provide guidance. When the inner end of the limit block contacts the step of the lifting platform, the part reaches the predetermined height, and the laser marking machine is restarted to complete the remaining marking. After marking is complete, the equipment's PLC controls the solenoid valve to start the cylinder, and the lifting platform returns to its original position, completing the workpiece marking and achieving multi-point marking on a single surface in one operation. This invention can automatically perform multi-layer marking on a single marking machine, reducing the number of workpiece rotations by one, lowering the operator's workload, preventing missed marking steps, and avoiding equipment investment and assembly line footprint.
