Description
Technical Field
[0001] This invention relates to the field of angle steel processing and manufacturing technology, specifically to an angle steel engraving device. Background Technology
[0002] In the field of angle steel processing, it is often necessary to engrave markings, specifications, or production batch information on the surface of angle steel to meet the needs of product identification and quality traceability. Currently, angle steel engraving is mostly done manually with marking and stamping or by handheld engraving machines. This method is not only labor-intensive and inefficient, but also makes it difficult to guarantee the consistency of the engraving position. It is easily affected by the operator's experience and condition, resulting in inconsistent product quality. To improve these problems, some companies have begun to use automated engraving equipment. However, existing equipment still has many shortcomings: First, the positioning, movement, and engraving actions of the equipment mostly rely on manual operation or semi-automatic control. The connection between each process requires manual intervention, resulting in a low degree of automation and difficulty in meeting the needs of large-scale continuous production. Second, the functional modules of the equipment are loosely arranged and occupy a large area, which is not conducive to the intensive use of workshop space. Third, the existing positioning methods are mostly single-sided positioning or simple clamping, which do not provide sufficient support and constraint for the two sides of the angle steel. During the engraving process, the workpiece is prone to displacement or rotation due to force, which seriously affects the engraving accuracy and consistency. Summary of the Invention

[0006] Preferably, both the first positioning plate and the second positioning plate are strip plates, and they are staggered in length direction; the guide plate and the lettering component mounted thereon are located at the position formed by the staggered arrangement of the first positioning plate and the second positioning plate.

[0008] Preferably, the positioning assembly further includes a base plate, a first bracket, and a second bracket; wherein the first bracket and the second bracket are both mounted on the base plate and are arranged with a relative distance between them; the first positioning plate and the second positioning plate are located between the first bracket and the second bracket, and the first positioning plate is mounted on the first bracket and the second positioning plate is mounted on the second bracket.
[0009] Preferably, the base plate is provided with a second guide rail, and the first bracket and the second bracket are slidably mounted on the second guide rail respectively; the first bracket and the second bracket are provided with a drive component that is connected to them in a transmission manner to drive them to move closer or further away synchronously.

Therefore, the structural design of this equipment realizes an automated process for continuous positioning and intermittent engraving of angle steel, effectively improving production efficiency while making the overall structure more compact and rational. Attached Figure Description
[0013] Figure 1 This is a schematic diagram of the structure of an angle steel engraving device proposed in this invention; Figure 2 This is a schematic diagram of an angle steel engraving device proposed in this invention in its working state. Detailed Implementation
[0014] Reference Figure 1 The present invention proposes an angle steel engraving device, comprising: a positioning component, a guide plate 1, and an engraving component 6, wherein: The positioning assembly includes a first positioning plate 2 and a second positioning plate 3. The first positioning plate 2 is arranged at an angle, and the second positioning plate 3 is symmetrically positioned on one side of the first positioning plate 2, with the second positioning plate 3 spaced apart from the first positioning plate 2 and arranged perpendicularly to each other. A guide plate 1 is located on the side of the first positioning plate 2 facing away from the second positioning plate 3, and the plane of the guide plate 1 is parallel to the plane of the first positioning plate 2; alternatively, the guide plate 1 is located on the side of the second positioning plate 3 facing away from the first positioning plate 2, and the plane of the guide plate 1 is parallel to the plane of the second positioning plate 3. The guide plate 1 has a first guide rail extending along its inclined direction, a carrier plate 4 slidably mounted to the first guide rail, and a first drive mechanism 5 driven by the carrier plate 4 to drive the carrier plate 4 to slide on the first guide rail. A lettering assembly 6 is mounted on the carrier plate 4. The lettering assembly 6 includes a lettering machine and a second drive mechanism; the second drive mechanism is driven by the lettering machine to drive the lettering machine to move two-dimensionally in a plane perpendicular to the first guide rail, thereby achieving character engraving on the surface of the workpiece.
[0015] Reference Figure 2During operation, the angle steel to be engraved is placed between the first positioning plate 2 and the second positioning plate 3. Since the two positioning plates are perpendicular to each other and arranged in a V-shape, the two sides of the angle steel are respectively attached to the inner sides of the two positioning plates, forming a double-sided positioning support based on the edge line of the angle steel. Subsequently, the first drive mechanism 5 is activated, driving the carrier plate 4 to slide along the first guide rail on the guide plate 1, driving the entire engraving assembly 6 to move along the inclined direction of the guide plate 1, so that the engraving machine reaches the preset engraving position; when the engraving machine is in place, the engraving machine is started, and at the same time the second drive mechanism is activated, driving the engraving machine to move relative to the positioning assembly in a plane orthogonal to the first guide rail, so that the engraving knife feeds perpendicular to the plane where the corresponding positioning plate is located, and engraves the mark on the side of the angle steel. Throughout the engraving process, the two positioning plates continuously provide stable support to both sides of the angle steel, ensuring that the workpiece does not shift or rotate under the engraving force. The first drive mechanism 5 and the second drive mechanism work together to realize the station switching of the engraving machine along the length of the angle steel and the feed control of a single engraving action, thereby completing the entire engraving operation.
[0016] Specifically: In this embodiment, the carrier plate 4 is further provided with guide rail pair A and guide rail pair B fixedly mounted on the slider of guide rail pair A; wherein, guide rail pair A, guide rail pair B and the first guide rail are orthogonal to each other in pairs to form independent motion trajectories along three orthogonal directions. The engraving machine is fixedly mounted on the slider of guide rail pair B. The second drive mechanism includes a second drive component A and a second drive component B, wherein the second drive component A is drivenly connected to the slider of guide rail pair A and is used to drive the slider to slide along the guide rail of guide rail pair A, and the second drive component B is drivenly connected to the slider of guide rail pair B and is used to drive the slider to slide along the guide rail of guide rail pair B. In operation, when the second drive component A drives the slider of guide rail pair A to slide, it can drive guide rail pair B and the engraving machine as a whole to move along the first direction; when the second drive component B drives the slider of guide rail pair B to slide, it can drive the engraving machine to move along the second direction; and when the first drive mechanism 5 drives the carrier plate 4 to slide along the first guide rail, it drives the engraving assembly 6 as a whole to move along the third direction. The three axes move independently and are not coupled, enabling precise positioning and flexible feeding of the engraving machine in three-dimensional space. This ensures accurate and controllable engraving trajectory and facilitates independent debugging and maintenance of each motion axis. Furthermore, guide rail pairs A and B adopt a stacked assembly structure, integrated on the carrier plate 4, resulting in a small overall footprint and facilitating miniaturization of the equipment. In addition, because the three guide rails are orthogonal to each other, the motion path of the engraving machine has a good geometric correspondence with the angle steel positioning reference, which simplifies the motion control algorithm, improves engraving positioning accuracy and repeatability, and thus ensures consistent engraving quality.
[0017] Furthermore, as a further preferred embodiment, this embodiment also includes a clamping cylinder 7 and a pressure block 8 fixedly connected to the telescopic end of the clamping cylinder 7; wherein, the clamping cylinder 7 is vertically positioned above the positioning assembly, and the pressure block 8 is horizontally positioned between the first positioning plate 2 and the second positioning plate 3. During engraving, the added clamping cylinder 7 and pressure block 8 allow the pressure block 8 to move downwards vertically after the angle steel is positioned between the first positioning plate 2 and the second positioning plate 3, so that the pressure block 8 presses against the inner side of the angle steel, thereby applying auxiliary clamping force to the angle steel during the engraving process. This structure, together with the first positioning plate 2 and the second positioning plate 3, forms an upper and lower clamping constraint, further limiting the warping, vibration, and displacement of the angle steel when subjected to engraving force, effectively ensuring the stability and consistency of the engraving quality.
[0018] As a further preferred option, in this embodiment, both the first positioning plate 2 and the second positioning plate 3 are strip plates, and they are staggered in length to form an open space on one side of the staggered area. The guide plate 1 and the engraving component 6 mounted on it are arranged parallel to the corresponding first positioning plate 2 or second positioning plate 3 at the position formed by the staggered first positioning plate 2 and the second positioning plate 3, so that the guide plate 1 and the engraving component 6 face the open space formed on one side of the staggered area. Thus, when the angle steel is placed between the two positioning plates, both ends of the angle steel are supported by different positioning plates, and the area to be engraved on one side corresponds exactly to the open space formed by the staggered two positioning plates. This ensures that the area is completely exposed within the working coverage of the engraving machine during engraving operations, without being obstructed by any positioning plate or guide plate 1, ensuring unobstructed operation and visibility of the engraving knife, facilitating quick loading and unloading of workpieces, and improving work efficiency.
[0019] As a further preferred embodiment, the positioning assembly in this embodiment also includes a base plate 9, a first bracket 10, and a second bracket 11. The base plate 9 is provided with a second guide rail; the first bracket 10 and the second bracket 11 are arranged at a relative distance and are slidably mounted on the second guide rail. The first bracket 10 and the second bracket 11 are provided with a drive assembly 12 that is connected to them to drive them to move synchronously closer or further apart. A first positioning plate 2 and a second positioning plate 3 are located between the first bracket 10 and the second bracket 11, with the first positioning plate 2 mounted on the first bracket 10 and the second positioning plate 3 mounted on the second bracket 11. This structural design allows for flexible adjustment of the spacing between the two positioning plates based on the specifications and dimensions of the angle steel to be engraved, especially the width of its two sides. This adapts to different types of angle steel without requiring changes to the positioning fixtures, thus improving the equipment's versatility and applicability. Furthermore, the synchronous movement of the two supports driven by the drive assembly 12 ensures that the first positioning plate 2 and the second positioning plate 3 always move symmetrically around their central plane. This maintains a constant edge position for the angle steel after insertion, ensuring consistency in the engraving reference when switching between different workpiece specifications and improving the repeatability of the engraving positioning. Simultaneously, the second guide rail provides guidance and constraint for the movement of the two supports, ensuring the parallelism and relative position stability of the two positioning plates during spacing adjustment, preventing inaccurate angle steel positioning due to skewness.
[0020] Furthermore, the drive assembly 12 includes a first screw and a second screw with opposite helical directions, a threaded sleeve with its two ends threadedly connected to the first screw and the second screw respectively, and a drive motor; wherein, the ends of the first screw and the second screw that are far apart from each other are connected to the first bracket 10 and the second bracket 11 respectively, a large gear is coaxially mounted on the threaded sleeve, and a small gear is mounted on the power output shaft of the drive motor, and the small gear meshes with the large gear. During operation, when the drive motor drives the threaded sleeve to rotate through the meshing transmission of the small gear and the large gear, since the first screw and the second screw have opposite helical directions, the rotation of the threaded sleeve will be synchronously converted into the first screw and the second screw moving in opposite or opposite directions in a linear motion along the axial direction, thereby driving the first bracket 10 and the second bracket 11 to move closer or further apart synchronously. This structural design employs a single drive motor as the power source, transmitting power to the threaded sleeve via gear meshing. This allows for the simultaneous symmetrical displacement of both supports, eliminating the need for separate drive components for each screw. This simplifies the drive system structure, reduces cost and control complexity, and results in a compact design conducive to miniaturized equipment layout. Furthermore, the threaded engagement between the screw and the threaded sleeve possesses a self-locking characteristic, maintaining the support position stably even after the drive motor stops. This eliminates the need for additional locking mechanisms, improving positioning reliability and safety. Moreover, the smooth gear meshing and precise transmission ratio ensure the synchronicity of the two screw movements and the consistency of displacement, thereby guaranteeing the positioning accuracy of the connected workpiece. Additionally, the axial dimension of this drive assembly 12 can be flexibly adjusted using the length of the threaded sleeve.
[0021] As a further preferred embodiment, this embodiment also includes a gantry frame 13; a positioning component is disposed below the crossbeam of the gantry frame 13; and a clamping cylinder 7 is fixedly installed on the crossbeam of the gantry frame 13.
[0022] As can be seen from the above, the present invention realizes fully automated collaborative operation from angle steel positioning and engraving station to single engraving action, and has the following advantages compared with the prior art: 1. By arranging the first positioning plate 2 and the second positioning plate 3 in a V-shape with vertical symmetry, the self-aligning positioning of the two sides of the angle steel through surface contact is achieved, which effectively constrains the offset and rotation during the engraving process. 2. By staggering the first positioning plate 2 and the second positioning plate 3, a clearance space is formed between the two positioning plates to accommodate the guide plate 1, so that the area of the angle steel to be engraved is fully exposed within the stroke range of the engraving knife to avoid structural interference, and it is also convenient to pick up and put down the angle steel. 3. The guide plate 1 and the corresponding positioning plate are arranged in parallel and the first guide rail extends in the inclined direction, so that the movement trajectory of the engraving component 6 driven by the carrier plate 4 along the angle steel edge is strictly consistent with the workpiece positioning reference, thus ensuring the engraving position accuracy in the length direction. 4. The lettering assembly 6 installed on the carrier plate 4 is driven by the second drive mechanism and can move in a plane orthogonal to the first guide rail, so that the lettering knife can feed perpendicularly to the plane of any positioning plate, thus having the ability to perform multi-faceted processing of lettering on both sides of the angle steel. 5. The system employs a double screw with opposite helical directions, a shared threaded sleeve, and a single motor gear drive. This not only achieves synchronous and symmetrical displacement of the two supports with a single power source, simplifying the drive system structure and reducing costs, but also utilizes the self-locking characteristic of the threads to ensure stable positioning without the need for an additional locking mechanism.
[0023] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
