[0002] With the rapid development of intelligent and precise modern industry, the manufacturing industry has reached new heights in its requirements for product precision and quality. In actual production processes, positioners, as key equipment for adjusting and positioning workpieces during machining, handle workpieces that exhibit significant diversity in shape, size, and weight. Examples include complex curved surface components in the aerospace field and large castings and forgings in heavy machinery manufacturing; these workpieces vary greatly.
[0003] In some scenarios, during the workpiece loading process of traditional positioners, workers perform loading and alignment operations on the positioners. For workpieces with special shapes (such as irregular structural parts) or large weights, workers face many difficulties in loading and alignment, requiring repeated adjustments based on experience, consuming a lot of time and energy, and severely restricting production efficiency. Thus, using manual alignment for loading and alignment of positioners results in low alignment efficiency, accuracy, and reliability. Utility Model Content

[0005] In a first aspect, this utility model discloses a laser alignment device, which includes: a cross laser, a laser bracket, a support component, and an optical axis base; the cross laser is fixed on the laser bracket, and both the laser bracket and the optical axis base are mounted on the support component; the laser bracket can slide left and right along the support component and can rotate relative to the support component to adjust the laser emission direction of the cross laser; the optical axis base is used to fix on the positioner so as to align the loading of the positioner by the cross-shaped laser beam emitted by the cross laser.
[0006] Optionally, the laser bracket includes a housing that passes through a support member. The housing has a first through hole, a second through hole, a third through hole, and a fourth through hole. The cross laser is installed in the cavity of the housing, and the laser emission direction of the cross laser is aligned with the first through hole.

The channel formed by the first fixing part and the second fixing part allows the support component to pass through. The second fixing part includes a mounting base, which is provided with a second mounting hole. Screws are used to fix the optical axis base to the top of the positioner through the second mounting hole.
[0008] Optionally, an anti-slip component is provided in the area where the mounting base contacts the positioner, and the anti-slip component is located between the mounting base and the positioner.
[0009] Optionally, the width of the mounting base of the second fixing part is greater than the width of the first fixing part, and the two ends of the mounting base are respectively provided with second mounting holes.

[0020] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a laser alignment device and positioner proposed according to this utility model. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0022] The specific solution of the laser alignment device provided by this utility model is described in detail below with reference to the accompanying drawings.
[0023] like Figure 1 and Figure 2 As shown, Figure 1This is a top view schematic diagram of a laser alignment device provided in an embodiment of the present invention. Figure 2 A three-dimensional structural diagram of a laser alignment device provided in an embodiment of this utility model is shown below. Figure 1 and Figure 2 As shown, the laser alignment device 10 includes: a cross laser 101, a laser bracket 102, a support component 103, and an optical axis base 104. The cross laser 101 is fixed to the laser bracket 102, and both the laser bracket 102 and the optical axis base 104 are mounted on the support component 103. The laser bracket 102 can slide left and right along the support component 103 and can rotate relative to the support component 103 to adjust the laser emission direction of the cross laser. The optical axis base 104 is used to fix itself on the positioner so that the cross-shaped laser beam emitted by the cross laser can be used to align the loading of the positioner.
[0024] Specifically, the cross laser 101 can emit two mutually perpendicular laser beams to form a cross-shaped spot. The cross laser 101 can emit red visible laser light. In this embodiment of the invention, a cross line is projected onto the worktable of the positioner, and the center of the workpiece is quickly aligned through the intersection of the cross lines. The horizontal and vertical laser beams of the cross lines are consistent with the horizontal and vertical directions of the workpiece.
[0025] Furthermore, the laser bracket 102 is used to mount the cross laser 101, thereby fixing the cross laser to the support member 103. The support member 103 can be fixed to the positioner, so that the laser emission direction of the cross laser on the support member 103 can be aligned with the worktable of the positioner. In an optional embodiment of this invention, the laser bracket 102 includes a housing that passes through the support member 103. The housing has a first through hole, a second through hole, a third through hole, and a fourth through hole. The cross laser 101 is installed in the cavity of the housing, and the laser emission direction of the cross laser 101 is aligned with the first through hole. The laser emitted by the cross laser 101 is emitted through the first through hole. Screws pass through the second and third through holes to tighten the cross laser. The second and third through holes are opposite to each other, and the fourth through hole is opposite to the support member 103. The screws are tightened onto the support member 103 through the fourth through hole.
[0026] Specifically, the housing has an internal cavity containing space capable of accommodating the cross-shaped laser 101. For example... Figure 2As shown, the housing in this embodiment of the present invention can be a cuboid structure. The lower half of the housing can pass through the support member 103, and the upper half of the housing is used to install the cross-shaped laser 101. Multiple through holes are provided on the housing. The cross-shaped laser 101 is installed inside the cavity of the housing, with the laser emission direction of the cross-shaped laser 101 aligned with the first through hole. The laser emitted by the cross-shaped laser 101 exits through the first through hole. Second and third through holes are also provided on opposite sides of the housing. Two screws are screwed into the second or third through hole respectively to tighten the cross-shaped laser 101. The fourth through hole is opposite to the support member 103, and the screw passes through the fourth through hole and is tightened onto the support member 103. In this way, the cross-shaped laser 101 is relatively fixed within the housing, preventing it from shifting and improving alignment accuracy. In use, the housing is slid on the support member 103, and after aligning the position, the screw in the fourth through hole is tightened to fix the housing to the support member 103.
[0027] Furthermore, as an optional embodiment of this utility model, the optical axis base 104 includes a first fixing part 1040 and a second fixing part 1041. The first fixing part 1040 and the second fixing part 1041 are fitted together and installed on the support member 103. The first fixing part 1040 and the second fixing part 1041 are provided with first mounting holes 1042 at corresponding positions. Screws are used to fix the first fixing part 1040 and the second fixing part 1041 to the support member through the first mounting holes 1042. The channel 1045 formed by the first fixing part 1040 and the second fixing part 1041 is for the support member 103 to pass through. The second fixing part 1041 includes a mounting base 1044. The mounting base 1044 is provided with a second mounting hole 1043. Screws are used to fix the optical axis base 104 to the top of the positioner through the second mounting hole 1043.
[0028] Specifically, such as Figure 3 As shown, Figure 3This is a schematic diagram of the structure of an optical axis base 104 disclosed in an embodiment of the present invention. It consists of a first fixing part 1040 and a second fixing part 1041, which are separate structures. The first fixing part 1040 and the second fixing part 1041 cooperate with each other. First mounting holes 1042 are provided at opposite positions on both the first fixing part 1040 and the second fixing part 1041. Screws are screwed into the first mounting holes 1042 on the first fixing part 1040 and the second fixing part 1041 to fix them. It is worth noting that the first mounting hole 1042 on the first fixing part 1040 extends through the entire thickness of the first fixing part 1040, and the first mounting hole 1042 on the second fixing part 1041 extends to a certain depth within the second fixing part 1041 to allow screws to pass through it. The lower side of the first fixing part 1040 and the upper side of the second fixing part 1041 have an arched structure. After the first fixing part 1040 and the second fixing part 1041 are fixed by screws, the lower side of the first fixing part 1040 and the upper side of the second fixing part 1041 form a channel through which the support member 103 passes. When fixing the optical axis base 104, the lower side of the first fixing part 1040 and the upper side of the second fixing part 1041 of the optical axis base 104 are pressed tightly against the support member 103. Then, the screws are aligned with the first mounting holes 1042 on the first fixing part 1040 and the second fixing part 1041 and tightened to complete the installation of the optical axis base 104. For example, the channel formed by the lower side of the first fixing part 1040 and the upper side of the second fixing part 1041 can be a circular channel as shown in the figure.
[0029] Furthermore, such as Figure 3 As shown, the second fixing part 1041 includes a mounting base 1044, on which a second mounting hole 1043 is provided. Screws are used to fix the optical axis base 104 to the top of the positioner through the second mounting hole 1043. The top of the positioner has a mounting hole that matches the second mounting hole 1043 on the optical axis base 104, and the optical axis base 104 is fixed to the positioner by screws.
[0030] Furthermore, in order to improve the stability between the optical axis base 104 and the positioner, as an optional embodiment of this utility model, the width of the mounting base 1044 of the second fixing part 1041 is greater than the width of the first fixing part 1040, and the two ends of the mounting base 1044 are respectively provided with second mounting holes 1043.
[0031] Specifically, in this embodiment of the invention, the width of the first fixing part 1040 can be 50mm, and the lateral width of the mounting base 1044 of the second fixing part 1041 can be 80mm, significantly larger than the 50mm width of the first fixing part 1040. This width difference provides a more stable support foundation for the overall structure, ensuring stability even under high-intensity external forces. The mounting base 1044 has symmetrically distributed second mounting holes 1043 at both ends, with a hole diameter of M8. The hole walls of the second mounting holes 1043 are nickel-plated, which not only enhances the wear resistance of the threads but also effectively prevents rust, ensuring reliable connection. The second mounting holes 1043 adopt a countersunk hole design, and when paired with matching countersunk bolts, the bolt heads are flush with the surface of the mounting base 1044, improving the overall aesthetics and avoiding the risk of impact caused by protrusions. The wider mounting base 1044 of the second fixing part 1041, with its larger size, can better distribute load pressure, ensuring the stability and safety of the entire laser alignment device.
[0032] Furthermore, in order to further improve the stability between the optical axis base 104 and the positioner, as an optional embodiment of this utility model, an anti-slip component is provided in the area where the mounting base 1044 contacts the positioner, and the anti-slip component is disposed between the mounting base 1044 and the positioner.
[0033] Specifically, the area where the mounting base 1044 contacts the positioner is equipped with an anti-slip component. This anti-slip component is molded from a high-friction coefficient nitrile rubber composite material, with a textured surface forming a dense array of diamond-shaped protrusions. Each protrusion is 0.8mm high and has a 60° apex angle, effectively increasing the contact area and allowing for micro-deformation under pressure to embed into the fine grooves on the positioner surface. Furthermore, in this embodiment, the anti-slip component is integrally molded with the mounting base 1044 using a secondary injection molding process. The mating surface is double-fixed using both chemical adhesive and mechanical interlocking structures, ensuring it does not detach under long-term vibration. Its working surface is coated with a nano-scale silicon carbide coating, significantly improving wear resistance while maintaining a high coefficient of friction (static coefficient of friction ≥ 1.2). In practical applications, this anti-slip component effectively suppresses dynamic slippage caused by the rotation or tilting of the positioner. Furthermore, the anti-slip components are designed with drainage channels on their edges to effectively drain oil and water stains, preventing a decrease in the coefficient of friction due to liquid media and ensuring reliable anti-slip performance even in wet or oily environments. In this way, the anti-slip components guarantee the stability between the mounting base 1044 and the positioner, preventing the crosshair laser from shifting and thus improving the alignment accuracy of the laser alignment device.
[0034] Furthermore, as an optional embodiment of this utility model, the support component 103 is a support rod with a circular cross-section. The support rod has scales evenly arranged from the middle to the left and right sides. The laser bracket can slide left and right along the support rod from the middle position and can rotate relative to the support component 103 to adjust the laser emission direction of the cross laser.
[0035] Specifically, in this embodiment of the invention, the support component 103 is a cylindrical support rod made of high-strength aviation aluminum alloy, precision machined by CNC lathe, and its outer surface is hard anodized, possessing excellent wear resistance and corrosion resistance. The support rod has high-precision graduations evenly distributed from the center to both sides, with a minimum graduation of 1mm. The graduation lines are made using laser etching technology, resulting in clear lines that never fade, facilitating accurate measurement and positioning. The portion of the laser bracket's housing that contacts the cylindrical support rod is inlaid with a self-lubricating copper alloy bushing, ensuring a tight fit with the support rod. Furthermore, the laser bracket is also equipped with an angle indicator dial with clear angle graduations. Combined with a pointer, this allows for a direct display of the current laser emission direction angle, greatly facilitating precise adjustments by the operator according to actual needs. The channel formed by the lower side of the first fixing part 1040 and the upper side of the second fixing part 1041 can be... Figure 3 The circular channel shown can be adapted to the cylindrical support rod provided in this embodiment of the utility model.
[0036] Furthermore, as an optional embodiment of this utility model, the length of the support component 103 is greater than the width of the positioner's worktable.
[0037] Specifically, the support component 103 is forged from high-strength alloy steel and precision-machined and heat-treated to achieve a total length exceeding the width of the positioner's worktable. This length design not only provides a stable foundation for the worktable but also, when the positioner performs multi-angle rotation operations, the portion of the support component 103 extending beyond the worktable forms a stable "balance wing," enhancing the overall structure's anti-tipping capability and ensuring stable operation even under high-speed rotation or heavy-load conditions. Furthermore, the extended length of the support component 103 allows for a wider adjustment range for the crosshair laser, accommodating the alignment of workpieces of different sizes and improving the flexibility, range, and reliability of the laser alignment device. The extended length also provides ample installation space, facilitating the installation and fixing of various auxiliary equipment and sensors, greatly enhancing the flexibility and convenience of equipment use and effectively meeting the diverse operational needs of complex industrial scenarios.
[0038] Furthermore, as an optional embodiment of this utility model, there are two optical axis bases 104. The two optical axis bases 104 are respectively disposed at both ends of the support member 103 and the optical axis bases 104 can slide left and right relative to the support member 103 to adapt to the installation position of the positioner. The installation position is used to fix the optical axis bases 104. The laser bracket slides left and right on the support member 103 between the two optical axis bases 104 and can rotate relative to the support member 103.
[0039] Specifically, two optical axis bases 104 are symmetrically distributed at both ends of the support component 103. By pushing the optical axis bases 104, the optical axis bases 104 can slide left and right along the support component 103. The support component 103 is provided with scales, so as to precisely adjust the displacement of the optical axis bases 104 relative to the support component 103, ensuring that it can accurately adapt to the needs of different installation positions of the positioner.
[0040] The technical solution disclosed in this utility model embodiment provides intuitive laser line indication via a cross-shaped laser. The cross-shaped laser beam can provide horizontal and vertical indications for the loading of the positioner. By aligning the intersection of the vertical and horizontal laser beams of the cross-shaped laser beam with the center of the workpiece placed on the positioner's worktable, and aligning the horizontal and vertical laser beams with the horizontal and vertical directions of the workpiece, it becomes easier for the worker to place the workpiece in the correct position on the positioner. Thus, the laser alignment device provided in this utility model embodiment, with its emitted cross-shaped laser beam, provides guidance for the loading and alignment of the positioner. This improves the alignment efficiency, accuracy, and reliability of the positioner's loading process.
[0041] Based on the same concept, this utility model embodiment also provides a positioner, such as Figure 4 As shown, Figure 4 This is a schematic diagram of a positioner according to an embodiment of the present invention. The positioner includes a positioner body 20 and a laser alignment device 10 provided in the above embodiment of the present invention. The laser alignment device 10 is fixed to the top of the positioner body 20.
[0042] Specifically, the positioner consists of a core positioner body 20 and a laser alignment device 10 provided in this embodiment, forming a collaborative operating system. The laser alignment device 10 is fixed to the top of the positioner body 20 via an optical axis base, enabling quick and stable installation. Once the laser alignment device 10 is fixed to the top of the positioner body 20, the two work together in a highly efficient, interconnected manner. When the positioner body 20 performs multi-angle and multi-directional rotation and tilting movements for loading, the laser alignment device 10 can emit a high-precision cross laser beam in real time to dynamically calibrate and position the workpiece, effectively compensating for errors caused by the positioner's movement, improving the workpiece alignment accuracy, and thus enhancing the workpiece's processing precision.
[0043] The positioner provided in this embodiment of the invention utilizes a cross-shaped laser beam as a visual indicator. This cross-shaped laser beam provides both horizontal and vertical direction guidance for loading the positioner. By aligning the intersection of the vertical and horizontal laser beams of the cross-shaped laser beam with the center of the workpiece placed on the positioner's worktable, and by aligning the horizontal and vertical laser beams with the horizontal and vertical directions of the workpiece, the operator can more easily place the workpiece in the correct position on the positioner. Thus, the laser alignment device provided in this embodiment of the invention, with its emitted cross-shaped laser beam, provides guidance for the positioner's loading and alignment. This improves the efficiency, accuracy, and reliability of the positioner's loading and alignment process.
[0044] It should be noted that the positioner provided in this embodiment of the present invention is based on the same application concept as the laser alignment device in the above embodiment. Therefore, the specific implementation of this embodiment can refer to the implementation of the aforementioned laser alignment device and has the same or similar beneficial effects. Repeated parts will not be described again.
[0045] It should be noted that the order of the above embodiments of the present invention is merely for descriptive purposes and does not represent the superiority or inferiority of the embodiments. The processes depicted in the accompanying drawings do not necessarily require a specific or sequential order to achieve the desired result. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
