Technical Field

[0001] The utility model relates to the technical field of fixtures, and particularly relates to a laser marking fixture and a laser marking device. Background Art

[0002] In modern manufacturing, cylindrical parts are widely used in various mechanical equipment and products. These cylindrical parts include, but are not limited to, bearings, gear shafts, piston pins, connecting rods, bolts, bushings, etc. During the production process, these parts usually need to be laser marked to label important information such as dimensional specifications, production batches, material models, production dates, or specific scale marks. These marks not only facilitate subsequent assembly and use but also contribute to product traceability and quality control. Laser marking has become the preferred method for marking this information due to its advantages of high precision, permanence, and no impact on the surface integrity of the parts.

[0003] However, existing laser marking fixtures often have the problem of limited application scope. Most fixtures can only adapt to cylindrical parts with a specific diameter and are difficult to meet the requirements of parts with different diameters. This results in the need to frequently replace or adjust the fixtures on the production line, which not only increases production costs but also reduces production efficiency. Summary of the Utility Model

[0004] The main object of the utility model is to propose a laser marking fixture, aiming to solve the technical problem that the fixtures in the prior art cannot adapt to cylindrical parts with multiple diameters.

[0005] To achieve the above object, the laser marking fixture proposed by the utility model includes a bottom plate and a clamping assembly.

The first support plate has a first inner side facing the second support plate, and the second support plate has a second inner side facing the first support plate. Both the first inner side and the second inner side are arranged at an angle to the top surface of the bottom plate. A V-shaped groove for accommodating the cylindrical part is formed between the first inner side and the second inner side. The angle between at least one of the first inner side and the second inner side and the top surface of the bottom plate is adjustable to adjust the width of the groove opening of the V-shaped groove.

[0006] Optionally, the first support plate includes a first plate body and a first movable plate. The first plate body is inclined and fixed on the bottom plate. The first movable plate is located on the side of the first plate body facing the second support plate, and the first movable plate is rotatably connected to the first plate body through a rotating shaft.

[0007] The first support plate further includes an adjustment fixing member, which is respectively connected to the first plate body and the first movable plate. The adjustment fixing member is used to adjust the rotation position of the first movable plate relative to the first plate body and maintain this position.

[0008] Optionally, the adjustment fixing member includes:

[0009] A torsion spring, which is sleeved on the rotating shaft.

[0024] The present utility model provides a laser marking jig.

[0025] In the embodiments of the present utility model, as Figure 1 shown, the laser marking jig includes a bottom plate 1 and a clamping assembly 2. The clamping assembly 2 includes a first support plate 21 and a second support plate 22 provided on the bottom plate 1. The first support plate 21 has a first inner side surface 212a facing the second support plate 22, and the second support plate 22 has a second inner side surface 222a facing the first support plate 21. Both the first inner side surface 212a and the second inner side surface 222a are arranged at an angle to the top surface of the bottom plate 1. A V-shaped groove 3 for accommodating cylindrical parts is formed between the first inner side surface 212a and the second inner side surface 222a. The angle between at least one of the first inner side surface 212a and the second inner side surface 222a and the top surface of the bottom plate 1 can be adjusted to adjust the groove opening width of the V-shaped groove 3.

[0026] Specifically, the bottom plate 1 can be a flat plate structure made of metal materials (such as aluminum alloy, stainless steel, etc.) or high-strength engineering plastics, and its upper surface should be kept flat to ensure the stable installation of the clamping assembly 2.

[0027] The two support plates, namely the first support plate 21 and the second support plate 22, can be made of metal materials (such as aluminum alloy, stainless steel, etc.) or high-strength engineering plastics to provide sufficient strength and stiffness. The two inner sides, namely the first inner side 212a and the second inner side 222a, can be flat surfaces or arc surfaces with a small curvature to better fit the surface of the cylindrical part.

[0028] Both the first inner side 212a and the second inner side 222a are arranged at an angle to the top surface of the bottom plate 1. This angle can be an acute angle, usually between 30° and 60°, to form a stable support structure. A V-shaped groove 3 for accommodating the cylindrical part is formed between the two inner sides. The "V-shaped groove 3" means that the groove can be a standard V shape or an approximately V-shaped structure. Such a design can better adapt to cylindrical parts with different diameters.

[0029] The key feature of this embodiment is that the angle between at least one of the first inner side 212a and the second inner side 222a and the top surface of the bottom plate 1 can be adjusted. This adjustability can be achieved through various mechanisms, such as a hinge structure, a gear transmission mechanism, a hydraulic or pneumatic adjustment system, etc. By adjusting this angle, the groove opening width of the V-shaped groove 3 can be changed, so as to adapt to cylindrical parts with different diameters.

[0030] The advantage of this design is that it provides a flexible and efficient solution that can adapt to various cylindrical parts with different diameters. By simply adjusting, the opening width of the clamping groove can be changed without replacing the entire fixture or using multiple special fixtures. This not only improves production efficiency, reduces equipment costs, but also increases the flexibility of the production line. At the same time, the adjustable support structure ensures that parts of different sizes can be stably and accurately positioned, guaranteeing the accuracy and consistency of laser marking. The combination of this versatility and precision makes the fixture of the present utility model have a wide application prospect in various production environments.

[0031] Optionally, the first support plate 21 includes a first plate body 211 and a first movable plate 212. The first plate body 211 is fixedly inclined on the bottom plate 1. The first movable plate 212 is located on the side of the first plate body 211 facing the second support plate 22, and the first movable plate 212 is rotatably connected to the first plate body 211 through a rotating shaft 213. The axis of the rotating shaft 213 is parallel to the length direction of the V-shaped groove 3. The side surface of the first movable plate 212 facing the second support plate 22 forms the first inner side surface 212a.

[0032] The first support plate 21 further includes an adjusting and fixing member 214. The adjusting and fixing member 214 is respectively connected to the first plate body 211 and the first movable plate 212. The adjusting and fixing member 214 is used to adjust the rotating position of the first movable plate 212 relative to the first plate body 211 and maintain this position.

[0033] During installation, the first plate body 211 includes two opposite support blocks 211a. Then, one end of the rotating shaft 213 is rotatably arranged on one support block 211a, and the other end of the rotating shaft 213 is rotatably arranged on the other support block 211a. The first movable plate 212 has a through hole for the rotating shaft 213 to pass through. The rotating shaft is installed with interference in this through hole. When the rotating shaft 213 rotates relative to the first plate body 211, the first movable plate 212 will also rotate accordingly.

[0034] It can be understood that this structure ensures that the first plate body 211 always remains stable, provides a solid foundation for the entire support structure, and enhances the overall rigidity and stability. Secondly, the opening width of the V-shaped groove 3 can be precisely controlled only by adjusting the angle of the first movable plate 212. This local adjustment is not only more convenient to operate but also enables more precise angle control. Compared with the overall rotation of the first support plate 21, this design greatly reduces the force required during adjustment and improves the convenience and precision of operation.

[0035] It should be noted that the design of this application is not limited to this. In other embodiments, the first support plate 21 can also be integrally designed as a single plate, and then this plate is rotatably arranged on the bottom plate 1 as a whole.

[0036] Optionally, the adjusting and fixing member 214 includes:

[0037] A torsion spring 214a. The torsion spring 214a is sleeved on the rotating shaft 213. One end of the torsion spring 214a is fixedly connected to the first plate body 211, and the other end is fixedly connected to the first movable plate 212. The torsion spring 214a is used to make the first movable plate 212 rotate in the direction towards the first plate body 211.

[0038] Adjusting bolt 214b, which passes through the first plate body 211 and abuts against the outer side surface of the first movable plate 212.

[0039] The working principle of this embodiment is as follows: Screwing in or out the adjusting bolt 214b can change its abutting position with the outer side surface of the first movable plate 212. When the adjusting bolt 214b is screwed in, the end of the adjusting bolt 214b applies pressure to the first movable plate 212, overcoming the torsion force of the torsion spring 214a, causing the first movable plate 212 to rotate around the rotating shaft 213, thereby increasing the included angle between the first inner side surface 212a and the first plate body 211. Conversely, when the adjusting bolt 214b is screwed out, under the action of the torsion spring 214a, the first movable plate 212 will rotate towards the first plate body 211, reducing the included angle. In this way, the opening width of the V-shaped groove 3 can be precisely adjusted. After the adjustment is completed, the threaded connection between the adjusting bolt 214b and the first plate body 211 provides sufficient friction to automatically maintain the position of the first movable plate 212 without an additional locking mechanism.

[0040] The advantages of this design are that it provides a simple, reliable and precise adjustment mechanism. The use of the torsion spring 214a ensures that the first movable plate 212 always maintains tension, eliminates possible gaps and shakes, and improves the stability of positioning. The design of the adjusting bolt 214b allows the operator to make fine angle adjustments for precise control. At the same time, the self-locking characteristic of the threaded connection eliminates the need for an additional locking device, simplifies the structure, and improves reliability. This mechanism is simple to operate, convenient to maintain, and has a low cost.

[0041] Of course, the design of the present application is not limited to this. In other embodiments, an arc-shaped rack can also be provided on the first movable plate 212, and the gear meshing with it is fixed on the first plate body 211, and the angle of the first movable plate 212 is adjusted by rotating the gear. Or, a hydraulic cylinder or a pneumatic cylinder is used to push the first movable plate 212, and the angle is precisely adjusted by controlling the pressure.

[0042] Preferably, to reduce costs, the structure of the second support plate 22 is the same as the structure of the first support plate 21.

[0043] That is to say, the second support plate 22 includes structures such as a second plate body 221 and a second movable plate 222, and specific reference can be made to the description of the first support plate 21 above. Different from the first support plate 21, the second support plate 22 is movable on the bottom plate 1 instead of being fixed to the bottom plate 1. Specifically, the second plate body 221 of the second support plate 22 is slidably provided on the bottom plate 1, and the second plate body 221 slides relative to the bottom plate 1 in the length direction of the V-shaped groove 3 to adjust the length of the V-shaped groove 3.

[0044] During use, the operator first determines the required length of the V-shaped groove 3 according to the length of the cylindrical part to be processed, and manually pushes or pulls the second plate body 221 to slide it on the bottom plate 1. During the sliding process, the second plate body 221 moves along a preset direction, ensuring the smoothness and straightness of the movement. When the second plate body 221 slides to the required position, that is, the length of the V-shaped groove 3 matches the length of the part to be processed, the operator stops sliding. At this time, the length adjustment of the V-shaped groove 3 is completed, and the cylindrical part to be processed can be placed for laser marking.

[0045] It is not difficult to understand that compared with the detachable type (by disassembling and reinstalling the second plate body 221 at different positions), which requires a disassembly and reinstallation process, the sliding adjustment only needs to be re-locked after sliding in place, greatly shortening the adjustment time.

[0046] Generally speaking, the sliding adjustment method not only ensures the adjustment accuracy and stability, but also significantly improves the operation efficiency and flexibility of use. This design enables the jig to quickly adapt to cylindrical parts of different lengths, greatly enhancing the adaptability and efficiency of the production line, and providing an efficient, accurate and easy-to-operate solution for laser marking of cylindrical parts of various specifications.

[0047] Optionally, a slider 23 is provided on the side edge of the second plate body 221 close to the bottom plate 1, and a sliding groove 11 slidably connected to the slider 23 is provided on the bottom plate 1. The sliding groove 11 extends in the length direction of the V-shaped groove 3. It can be understood that the sliding cooperation mode of the slider 23 and the sliding groove 11 is easy to manufacture and assemble, reduces the production cost, and has a simple structure, which is easy to clean and replace worn parts.

[0048] It should be noted that the design of the present application is not limited to this. In other embodiments, the sliding groove 11 can also be provided on the second plate body 221, and the slider 23 can be provided on the bottom plate 1.

[0049] The present utility model also proposes a laser marking device, which includes a laser marking jig. The specific structure of the laser marking jig refers to the above embodiments. Since this laser marking device adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0050] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
