Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment for aluminum square profile processing, specifically to a laser marking and positioning fixture for aluminum square profiles. Background Technology
[0002] Laser marking is a crucial step in the production and processing of aluminum square profiles. It is used to mark key information such as model number, specifications, and production batch number on the surface of the aluminum square profiles, facilitating subsequent traceability, identification, and use. Laser marking requires extremely high positioning accuracy. If the positioning deviation is too large, it will lead to the marking position being off-center, the information being blurred, or even the scrapping of the profile, increasing production costs.
[0003] Existing laser marking and positioning fixtures for aluminum square profiles are mostly fixed structures, only suitable for aluminum square profiles of a single specification and shape, resulting in poor versatility. For aluminum square profiles with irregular grooves or protrusions at the ends, traditional positioning fixtures cannot achieve precise axial and radial positioning, easily leading to profile wobbling and positioning misalignment. Furthermore, the limiting structures of existing fixtures are mostly fixed, unable to be flexibly adjusted according to the marking position requirements, thus limiting their applicability. In addition, some fixtures have unreasonable clamping structure designs, easily causing scratches and damage to the surface of the aluminum square profile during clamping, affecting the product's appearance quality, and insufficient clamping stability further affects marking accuracy.
[0004] Therefore, there is an urgent need for a laser marking and positioning fixture that can adapt to aluminum square profiles of different specifications and with different end shapes, with precise positioning, convenient adjustment, and effective protection of the profile surface, in order to solve the shortcomings of existing technologies. Utility Model Content
[0005] The purpose of this invention is to provide a laser marking and positioning fixture for aluminum square profiles. Addressing the problems of poor versatility, insufficient positioning accuracy, and easy damage to the profile surface in existing laser marking and positioning fixtures for aluminum square profiles, this invention provides a laser marking and positioning fixture for aluminum square profiles that achieves precise positioning of aluminum square profiles of different specifications and with different end shapes, improving marking accuracy and efficiency, while protecting the profile surface from damage and expanding the applicability of the fixture.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A laser marking and positioning fixture for aluminum square profiles includes a fixture table and a transverse positioning plate fixedly installed on one side of the fixture table. The transverse positioning plate has an adjustment slot along its length, and an adjustable limiting component is installed in the adjustment slot. The adjustable limiting component includes a limiting block slidably installed in the adjustment slot and a locking member installed on the side of the transverse positioning plate facing away from the aluminum square profile. The limiting block and the locking member are clamped and fixed to the transverse positioning plate by fasteners. A non-circular limiting block is detachably fixedly installed on the limiting block, and the outer contour of the non-circular limiting block is adapted to the non-circular groove or non-circular protrusion at the end of the aluminum square profile to be processed.
[0007] Furthermore, a clamping assembly is installed on the tooling table, the clamping assembly including a drive cylinder, a sliding positioning plate, and a guide rail; the top surface of the tooling table has a guide groove extending perpendicular to the surface of the transverse positioning plate, the guide rail is fixedly installed in the guide groove, and the sliding positioning plate slides in cooperation with the guide rail through a downwardly extending connecting part; the drive cylinder is fixedly installed at the bottom of the tooling table, and the piston rod end of the drive cylinder is fixedly connected to the connecting part, driving the sliding positioning plate to move toward or away from the transverse positioning plate.
[0008] Furthermore, multiple guide grooves are provided, and all guide grooves are symmetrically arranged with the longitudinal center line of the sliding positioning plate as the axis of symmetry, to ensure that the sliding positioning plate is subjected to uniform force and slides smoothly during movement, thereby improving clamping stability.
[0009] Furthermore, the connecting part extends through the guide groove to the bottom of the tooling table, and the lower end of the connecting part extends to both sides to form a reinforcing plate. The reinforcing plate and the sliding positioning plate are located on the upper and lower sides of the tooling table respectively, and the two are fixedly connected at the corresponding positions of each guide groove, which enhances the connection strength between the connecting part and the sliding positioning plate, avoids deformation and shaking of the sliding positioning plate during clamping, and ensures positioning accuracy.
[0010] Furthermore, the sliding positioning plate and the transverse positioning plate are arranged parallel to each other. Flexible protective pads are attached and fixed to the side surfaces of the transverse positioning plate and the sliding positioning plate facing the aluminum square profile. The flexible protective pads are made of soft materials such as rubber and silicone, which can not only avoid scratching or crushing the surface of the aluminum square profile during clamping, but also increase the friction of the contact surface and further improve the clamping stability.
[0011] Furthermore, the transverse positioning plate is provided with scale lines, and the scale values of the scale lines correspond to the axial pushing and positioning positions of the irregular-shaped limiting block on the aluminum square profile. This allows the operator to accurately adjust the position of the irregular-shaped limiting block according to the marking position requirements, thereby improving positioning efficiency and accuracy.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. High versatility: By setting adjustable limit components and detachable irregular limit blocks, the irregular limit blocks can be replaced according to the irregular structure of the end of the aluminum square profile to be processed, and the limit blocks can slide along the adjustment channel to adjust their position, adapting to aluminum square profiles of different specifications and different end irregular structures, greatly expanding the scope of application of the tooling and reducing the investment cost of production equipment.
[0013] 2. Precise positioning: The adjustable limit component achieves precise positioning through scale lines, and the locking part and the limit block work together to firmly fix the limit structure and avoid positioning deviation; the clamping component guides the sliding positioning plate to move smoothly through the guide rail, and the symmetrically arranged guide grooves ensure uniform clamping force, further improving positioning accuracy and ensuring the quality of laser marking.
[0014] 3. Protect the surface of the profile: The flexible protective pads on the horizontal positioning plate and the sliding positioning plate can effectively prevent scratches and pressure damage to the surface of the aluminum square profile during clamping and positioning, ensuring the appearance quality of the product and reducing the scrap rate of the profile.
[0015] 4. Convenient operation and high stability: The drive cylinder drives the sliding positioning plate to achieve automatic clamping, reducing the labor intensity of operators; the setting of the reinforcing plate enhances the connection strength of the clamping structure, avoids deformation and shaking of the sliding positioning plate, ensures long-term stable operation of the tooling, and improves production efficiency.

Detailed Implementation
[0017] The technical solutions of the present invention will now be described in full with reference to the accompanying drawings of the embodiments.
[0018] like Figure 1-2 As shown, the present invention provides a laser marking and positioning fixture for aluminum square profiles, including a fixture table 1, a transverse positioning plate 2, an adjustable limiting component 3, an irregularly shaped limiting block 4, and a clamping component 5. The specific structure and connection relationship of each component are as follows: The tooling table 1 is a rectangular plate structure made of high-strength steel to ensure the overall stability and load-bearing capacity of the tooling. Support feet can be installed on the bottom of the tooling table 1 for easy fixing and horizontal adjustment. A transverse positioning plate 2 is vertically fixed to the upper edge of the tooling table 1. The transverse positioning plate 2 is made of steel plate and has a through-slot 21 along its entire length. The adjustment slot 21 is rectangular and is used to assemble the adjustable limit assembly 3.
[0019] The adjustable limiting component 3 includes a limiting block 31 and a locking element 32. The size of the limiting block 31 is adapted to the adjusting channel 21 and can slide freely along the adjusting channel 21. The limiting block 31 has a threaded hole on the side facing the aluminum square profile for detachable and fixed installation of the irregularly shaped limiting block 4. The locking element 32 is a square pressure plate, the size of which is larger than the size of the adjusting channel 21 to prevent the locking element 32 from sliding into the adjusting channel 21. The limiting block 31 and the locking element 32 are clamped and fixed to the transverse positioning plate 2 by bolts (fasteners). When it is necessary to adjust the position of the limiting block 31, loosen the bolts, push the limiting block 31 to slide along the adjusting channel 21 to the designated position, and then tighten the bolts to complete the fixing of the limiting block 31. The operation is convenient.
[0020] The irregularly shaped limiting block 4 is made of wear-resistant plastic or aluminum alloy. Its outer contour is adapted to the irregularly shaped groove or protrusion at the end of the aluminum square profile to be processed. The irregularly shaped limiting block 4 is provided with a through hole corresponding to the threaded hole of the limiting block 31. The irregularly shaped limiting block 4 is fixed on the limiting block 31 by bolts. When processing aluminum square profiles with different irregular end structures, it is only necessary to remove the bolts and replace the corresponding irregularly shaped limiting block 4. It has strong versatility.
[0021] The clamping assembly 5 is installed on the fixture table 1 to clamp and fix the aluminum square profile, preventing the profile from shaking during the marking process. The clamping assembly 5 includes a drive cylinder 51, a sliding positioning plate 52, a guide rail 53, a connecting part 54, and a reinforcing plate 55. The top surface of the fixture table 1 has three guide grooves 11, which are symmetrically arranged about the longitudinal center line of the sliding positioning plate 52. The extension direction of the guide grooves 11 is perpendicular to the surface of the transverse positioning plate 2. The guide rail 53 is fixedly installed in the guide groove 11 by bolts. The guide rail 53 is adapted to the guide groove 11 to ensure that the guide rail 53 is firmly installed and does not loosen.
[0022] The sliding positioning plate 52 is a rectangular plate structure, which is parallel to and opposite to the transverse positioning plate 2. The bottom surface of the sliding positioning plate 52 is integrally formed with a downwardly extending connecting part 54. The lower end of the connecting part 54 is slidably engaged with the guide rail 53, so that the sliding positioning plate 52 can move smoothly along the guide rail 53. The connecting part 54 extends through the guide groove 11 to the bottom of the tooling table 1. The lower end of the connecting part 54 extends to both sides to form a reinforcing plate 55. The reinforcing plate 55 is a rectangular plate, which is parallel to the sliding positioning plate 52. The reinforcing plate 55 and the sliding positioning plate 52 are located on the upper and lower sides of the tooling table 1, respectively, and the two are fixedly connected at the corresponding positions of each guide groove 11 to enhance the connection strength between the connecting part 54 and the sliding positioning plate 52 and prevent the sliding positioning plate 52 from deforming or shaking during the clamping process.
[0023] The drive cylinder 51 is fixedly installed on the bottom of the tooling table 1 by a bracket. The piston rod end of the drive cylinder 51 is fixedly connected to the lower end of the connecting part 54. The drive cylinder 51 is a telescopic cylinder. Its piston rod is controlled to extend and retract through an external air circuit, thereby driving the sliding positioning plate 52 to move toward or away from the transverse positioning plate 2, realizing automatic clamping and loosening of the aluminum square profile, reducing the labor intensity of operators and improving production efficiency.
[0024] Both the transverse positioning plate 2 and the sliding positioning plate 52 have flexible protective pads (not shown in the figure) glued to the side of the aluminum square profile. The flexible protective pads are made of silicone pads with a thickness of 2-3mm. The silicone pads have a smooth and soft surface, which can not only prevent scratches and pressure damage to the surface of the aluminum square profile during clamping and positioning, but also increase the friction of the contact surface and further improve the clamping stability.
[0025] The top surface of the transverse positioning plate 2 is provided with scale lines (not shown in the figure). The scale lines are arranged along the extension direction of the adjustment channel 21. The scale value of the scale line corresponds to the axial pushing and positioning position of the irregular limit block 4 on the aluminum square profile. For example, the zero scale line corresponds to the marking start position of the aluminum square profile. The operator can accurately adjust the position of the limit block 31 according to the marking position requirements by referring to the scale line, thereby improving the positioning efficiency and accuracy.
[0026] The working process of this embodiment is as follows: 1. Preparation: Based on the irregular structure of the end of the aluminum square profile to be processed, select the corresponding irregular limiting block 4 and fix the irregular limiting block 4 on the limiting block 31 with bolts; refer to the scale line on the transverse positioning plate 2, loosen the bolts, push the limiting block 31 to slide along the adjusting through groove 21 to the designated position, and then tighten the bolts to complete the positioning and fixing of the adjustable limiting component 3.
[0027] 2. Profile placement: Place the aluminum square profile to be processed on the tooling table 1, so that the end of the aluminum square profile is in contact with the irregular limiting block 4 to achieve axial positioning of the aluminum square profile, and one side of the aluminum square profile is in contact with the transverse positioning plate 2 to achieve preliminary radial positioning.
[0028] 3. Clamping and fixing: The piston rod of the drive cylinder 51 is extended by controlling the external air circuit. The drive cylinder 51 pushes the connecting part 54 to slide along the guide rail 53, thereby driving the sliding positioning plate 52 to move towards the transverse positioning plate 2 until the flexible protective pad on the sliding positioning plate 2 is tightly attached to the other side of the aluminum square profile, clamping and fixing the aluminum square profile. The clamping force can be controlled by adjusting the air circuit pressure to avoid excessive force damaging the profile.
[0029] 4. Laser marking: After the aluminum square profile is clamped and fixed, the laser marking equipment is started to laser mark the aluminum square profile. During the marking process, the tooling is positioned stably, which can effectively prevent the profile from shaking and ensure the marking accuracy.
[0030] 5. Material Removal: After marking is completed, the piston rod of the control drive cylinder 51 retracts, causing the sliding positioning plate 52 to move away from the transverse positioning plate 2, loosening the clamping of the aluminum square profile, and taking out the processed aluminum square profile to complete one marking operation.
[0031] When processing aluminum square profiles of different specifications and with different end shapes, simply replace the corresponding irregular shape limit block 4 and adjust the position of the limit stop block 31 to quickly adapt to the requirements. The operation is convenient and highly versatile.
