Description

Technical Field

[0001] This article relates to a transplanting fixture for a laser marking machine. Background Technology

[0002] In the laser marking production process, to ensure marking accuracy, a transfer fixture is needed to position and clamp the workpiece before transferring it to the marking station of the laser marking machine. Existing technologies for transfer fixtures have the following core problems:

[0003] Poor adaptability: Traditional fixtures mostly use a single clamping structure, which can only be adapted to one type or size of workpiece. When the workpiece to be marked includes different sizes such as long strips and short strips, the fixture needs to be changed or complex adjustments need to be made, which leads to extended equipment downtime and seriously affects the continuous operation efficiency under high-speed marking conditions.

[0004] Insufficient clamping convenience: Although long strip workpieces are easy to manually hold and position due to their length, a stable clamping structure is required to prevent marking from shaking; short strip workpieces are short (usually 30-80mm) and the operating space is limited when manually picking them up and putting them down, which can easily lead to positioning deviations. In addition, traditional fixtures cannot adjust the position of the clamping area of ​​short strip workpieces, further reducing clamping efficiency.

[0005] Insufficient positioning accuracy and safety: The load-bearing structure of existing fixtures is mostly fixed, which can easily lead to problems of clamping too loosely or too tightly when there are slight differences in the size of the workpiece. This not only affects the marking quality but may also damage the workpiece. At the same time, some movable clamping structures lack stroke limits, which can easily lead to the risk of parts slipping off and threaten the safe operation of the equipment.

[0006] Therefore, there is an urgent need for a transfer fixture that can simultaneously adapt to both long and short workpieces, is easy to clamp, has precise positioning, and is safe and stable, in order to meet the operational requirements of high-speed laser marking machines. Utility Model Content

[0007] This invention aims to solve the technical problems of "poor adaptability, low clamping efficiency, insufficient positioning accuracy, and lack of operational safety" in the existing laser marking machine transfer fixtures. It provides a transfer fixture for laser marking machines that enables synchronous adaptation and clamping of long and short workpieces, shortens equipment downtime, and improves marking accuracy and operational safety.

[0008] A transfer fixture for a laser marking machine includes a base, a movable worktable, a long strip workpiece clamping area, and a short strip workpiece clamping area;

[0009] The lower surface of the worktable is slidably connected to the base via a worktable guide rail. The worktable can move along the extension direction of the worktable guide rail. The long strip workpiece clamping area and the short strip workpiece clamping area are both located on the upper surface of the worktable and are parallel to each other.

[0010] The long strip workpiece clamping area includes a clamping cylinder, several support blocks of equal height, and an outer clamping component; the head of the clamping cylinder is provided with an inner clamping component that can move radially along the workpiece, the inner clamping component includes two relatively movable inner clamping blocks, and the outer clamping component includes two relatively movable outer clamping blocks; the inner clamping component and the outer clamping component cooperate to achieve clamping and positioning of the long strip workpiece, and the support blocks are used to support the bottom of the long strip workpiece;

[0011] The short strip workpiece clamping area includes a support base, a rod cylinder, a slider, and a rod cylinder guide rail; the top of the support base is provided with several limiting units adapted to the shape of the short strip workpiece, and the limiting units are used to circumferentially limit the short strip workpiece; the bottom of the support base is fixedly connected to the cylinder body of the rod cylinder, the lower surface of the rod cylinder is fixedly connected to the slider, the slider is slidably disposed in the rod cylinder guide rail, and the rod cylinder guide rail is fixed to the upper surface of the worktable;

[0012] The push rod end of the rod cylinder is fixedly connected to the worktable. When the push rod of the rod cylinder extends or retracts, it can drive the bearing seat to move along the extension direction of the rod cylinder guide rail.

[0013] Furthermore, the end of the rod-driven cylinder guide rail is provided with a limiting baffle to restrict the movement stroke of the bearing seat, and the lower end of the limiting baffle is fixedly connected to the worktable. When the rod-driven cylinder pushes the bearing seat to the rightmost end, the end of the bearing seat will abut against the baffle, preventing the bearing seat from slipping off the guide rail. This prevents parts from falling off and being damaged, and workpieces from falling, ensuring the safety of the fixture operation during high-speed marking and reducing the risk of equipment failure.

[0014] Furthermore, the base is equipped with a rodless cylinder for driving the worktable to move along the worktable guide rail. The slider of the rodless cylinder is fixedly connected to the lower surface of the worktable, and the extension direction of the rodless cylinder is consistent with the extension direction of the worktable guide rail. By using the rodless cylinder, the clamping area of ​​the clamped workpiece can be accurately transferred to the marking station, reducing the time spent by manual labor or other driving methods, improving workpiece transfer efficiency and positioning accuracy, and adapting to high-speed marking rhythms.

[0015] Furthermore, the top of the support block is provided with an arc-shaped groove that fits the bottom of the elongated workpiece, and several of these support blocks are evenly distributed along the length of the elongated workpiece. The arc-shaped groove fits against the bottom of the elongated workpiece, evenly distributing the workpiece weight. This prevents bending or swaying caused by uneven local stress due to the workpiece's length. Simultaneously, the evenly distributed support blocks further improve the workpiece clamping stability, providing a foundation for subsequent high-precision marking.

[0016] Furthermore, the external clamping component includes a sliding assembly for driving the relative movement of the two external clamping blocks. The sliding assembly is limited internally by a sliding rod, and a positioning screw is provided on the outer wall of the sliding assembly. The sliding rod ensures precise movement of the external clamping blocks, and the positioning screw fixes the clamping position. This design is adaptable to long, strip-shaped workpieces of different radial dimensions, ensuring stable and non-shifting positions after clamping, preventing workpiece displacement during marking, and improving the adaptability and clamping reliability of the external clamping component.

[0017] Furthermore, a polyurethane buffer pad is provided on the side of the limiting baffle facing the support. The polyurethane buffer pad absorbs the impact force when the support abuts against the baffle, avoiding rigid contact. This reduces collision wear between the support and the baffle, extends their service life, reduces collision noise, makes the movement and stopping of the support smoother, and ensures the stability of short strip workpieces during clamping and loading.

[0018] Furthermore, cable chains are installed on both sides of the workbench, and the air hoses of both the rodless and rod-type cylinders are threaded through the cable chains. The cable chains can neatly store the air hoses, preventing them from becoming tangled, rubbed, or pulled as the workbench moves. This protects the air hoses from damage, reduces equipment downtime due to air hose failures, and improves the overall operational reliability of the fixture.

[0019] Beneficial effects:

[0020] This device is a transfer fixture for laser marking machines. By setting up long and short workpiece clamping areas in parallel on a movable worktable, two types of workpieces can be clamped simultaneously without changing the fixture. It effectively adapts to the needs of workpieces with varying models under high-speed marking conditions, greatly saves clamping time and improves the utilization rate of laser marking equipment.

[0021] In terms of loading and unloading, to address the problem of inconvenience in loading and unloading short strip workpieces, a rod-driven cylinder is used to move the carrier along the slide rail to the manual operation area. With the matching workpiece limit unit on the carrier, both the convenience of clamping and the accuracy of positioning are taken into account.

[0022] In terms of clamping, long strip-shaped workpieces are double-clamped by internal and external clamping components and supported by height-equal support blocks, while short strip-shaped workpieces are circumferentially limited by limiting units, effectively preventing workpiece wobbling or displacement and ensuring the positioning accuracy of laser marking. Simultaneously, a limiting baffle at the end of the rod-type cylinder guide rail prevents the support seat from slipping, and the stable clamping structure for both types of workpieces also prevents them from falling off, improving the safety and reliability of the fixture operation. The worktable can move along the guide rail, allowing simultaneous operation of the two clamping areas to reduce non-marking time, meeting the efficiency requirements of high-speed marking and further improving overall production efficiency.
