Description

Technical Field

[0001] This utility model relates to the field of mechanical component design, specifically to an adjustable mounting device for dual lasers. Background Technology

[0002] Currently, in the field of structured light measurement technology, lasers and cameras are used together to construct sensors. In applications such as wheelset inspection and gap difference measurement, using a single line laser often suffers from insufficient brightness and limited detection range. Therefore, using dual lasers has become a better choice, namely, deploying lasers on both sides of the object to be measured, with the two lasers projecting laser strips onto the surface of the object from the left and right sides respectively. During sensor assembly, this solution requires pre-adjustment to ensure that the light planes projected by the two lasers coincide, i.e., the two projected laser strips overlap. This makes the fixing and adjustment of the dual lasers a design challenge.

[0003] Existing adjustment and assembly tools place strict requirements on the skill level of assembly operators. For example, a dual-laser adjustment mounting base disclosed in patent document CN220749664U only allows manual adjustment of the laser's pitch angle via the rotating shaft 9 and the rotation angle via the clamping part 2. The adjustment process relies heavily on the operator's experience, resulting in unsatisfactory adjustment accuracy and efficiency. Furthermore, during the adjustment process, the laser is continuously subjected to the clamping force of the clamping part 2. After adjustment, the clamping part 2 needs to be removed, introducing variables into the laser before and after adjustment. This not only increases the instability of the adjustment but also adds steps to the production process.

[0004] Therefore, a device is needed to adjust the alignment of light planes more quickly and accurately. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this utility model provides an adjustable mounting device for dual lasers. This device, based on the rotation adjustment screw I, the pitch adjustment screw, and the rotation adjustment screw II, can finely adjust the spatial position relationship of the laser strips emitted by the two line lasers, so as to achieve the high overlap of the two laser strips.

[0006] The technical solution is as follows:

[0007] An adjustable mounting device for dual lasers includes: a first adjustment seat and a second adjustment seat respectively fixedly mounted on the two free ends of a support rod;

[0008] The first adjustment seat includes a support frame, a cross clamp, a clamping part I, a rotary adjustment screw I, a pitch adjustment screw, and a rotating shaft;

[0009] The support frame includes a base plate, upright plates, and a cover plate; there is a pair of upright plates, which are disposed opposite to each other between the base plate and the cover plate.

[0010] Therefore, a through hole I is provided at a relative position in the middle of the upright plate, and the rotating shaft is externally threaded, which passes through one through hole of the cross clamp and is screwed onto the upright plate; the other through hole of the cross clamp is used to install the laser to be adjusted, and a through hole II is provided at the cover plate position corresponding to the emitting end of the laser to be adjusted, and the diameter of the through hole II is larger than the outer diameter of the emitting end of the laser.

[0011] The height at which the laser to be adjusted is mounted on the cross clamp is less than the height of the laser to be adjusted; the free end of the laser to be adjusted is provided with a clamping part I, which can hold the laser to be adjusted and one end of which extends to form a protrusion I; the protrusion I is located between the two upright plates.

[0012] Two rotary adjusting screws I are provided, which are screwed onto a pair of upright plates respectively. The free ends of the two rotary adjusting screws I abut against the two sides of the protrusion I respectively. Under the action of external force, the rotary adjusting screws I can apply a pushing force to the protrusion, thereby driving the clamping part to rotate.

[0013] Two or more pitch adjusting screws are provided along the length of the cross clamp; they are screwed onto the cover plate respectively, and the free ends of each pitch adjusting screw abut against the upper surface of the cross clamp; under the action of external force, the pitch adjusting screws apply a pushing force to the cross clamp, causing the cross clamp to rotate.

[0014] The second adjusting seat includes a support, a clamping part II, and a rotating adjusting screw II;

[0015] The support has a through hole for mounting another laser to be adjusted, and the side wall has an opening along the length of the hole. A locking screw is provided at the opening to hold the laser. The top of the support is recessed to form a cavity.

[0016] The clamping part II is clamped on the top end of the laser to be adjusted, and one end of it extends to form a protrusion II; the clamping part II is disposed in the cavity;

[0017] Two rotary adjusting screws II are provided, which are screwed onto the side wall of the cavity respectively. The free ends of the two rotary adjusting screws II abut against the two sides of the protrusion II respectively. Under the action of external force, the rotary adjusting screws II can apply a pushing force to the protrusion II, thereby driving the clamping part II to rotate.

[0018] To achieve uniform force application, two pitch adjustment screws are provided at one end of the cross clamp along its width.

[0019] Furthermore, it also includes a linear screw slide, wherein the first adjustment seat and / or the second adjustment seat are disposed on the slider of the linear screw slide.

[0020] Preferably, both ends of the support rod are inclined inward at 20° to 60°.

[0021] Preferably, the relationship between the rotation angle and feed amount of the rotary adjusting screw I, the pitch adjusting screw and the rotary adjusting screw II is marked at their respective installation positions.

[0022] Preferably, the mounting positions of the rotary adjusting screw I, the pitch adjusting screw, and the rotary adjusting screw II are provided with a 360° angle scale ring in the coaxial circumferential direction.

[0023] Preferably, the upright plate is L-shaped, and the wider side of the upright plate is connected to the cover plate.

[0024] This design scheme uses rotary adjusting screw I, pitch adjusting screw, and rotary adjusting screw II to precisely adjust the pitch and rotation angles of the laser strips emitted by the two line lasers. The feed amount for each adjustment is accurately calculated using the screw pitch, eliminating reliance on subjective human judgment. In other words, by selecting the appropriate screw specifications, the exact angle of laser rotation corresponding to each full rotation of the screw during adjustment can be determined.

[0025] For example, using an M3×0.5 screw (0.5 refers to the screw pitch), rotating it 1 turn results in a feed of 0.5mm. Using the arc length formula: L=(n×π×r) / 180, we can derive the central angle n=(180L) / (πr), which means the laser rotated by 0.03 degrees.

[0026] Furthermore, once the laser is adjusted, the relevant tooling does not need to be disassembled and can be directly put into use, reducing production steps and avoiding unnecessary variables introduced by disassembling and adjusting components.

[0027] The laser adjustment device using this structure features high operability, high precision, clear adjustment direction, accurate adjustment data for reference, and high efficiency. Attached Figure Description

[0032] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] An adjustable mounting device for dual lasers, such as Figure 1 As shown, it includes: a first adjusting seat 1 and a second adjusting seat 3, which are respectively fixedly installed at the two free ends of the support rod 6;

[0034] like Figure 2 , 3 As shown, the first adjustment seat 1 includes a support frame 11, a cross clamp 12, a clamping part I 13, a rotary adjustment screw I 14, a pitch adjustment screw 15, and a rotating shaft 16;

[0035] The support frame 11 includes a base plate 17, upright plates 18, and a cover plate 19; there is a pair of upright plates 18, which are disposed opposite to each other between the base plate 17 and the cover plate 19.

[0036] The cross clamp includes two mutually perpendicular mounting holes that can clamp each other. One mounting hole is used to clamp the rotating shaft 16, and the other mounting hole is used to install the laser 4 to be adjusted.

[0037] Therefore, a through hole I is provided in the middle of the vertical plate 18 at a relative position, and the rotating shaft 16 is externally threaded, which passes through one through hole of the cross clamp 12 and is screwed onto the vertical plate 18; the other through hole of the cross clamp is used to install the laser to be adjusted 4, and a through hole II is provided at the position of the cover plate 19 corresponding to the emitting end of the laser to be adjusted 4, and the diameter of the through hole II is larger than the outer diameter of the emitting end of the laser.

[0038] The height of the cross clamp 12 for mounting the laser to be adjusted 4 is less than the height of the laser to be adjusted 4; the free end of the laser to be adjusted 4 is provided with a clamping part I 13, which can hold the laser to be adjusted 4 tightly and one end of which extends to form a protrusion I 20; the protrusion I 20 is located between the two vertical plates 18.

[0039] Two rotary adjusting screws I 14 are provided, which are screwed onto a pair of upright plates 18 respectively. The free ends of the two rotary adjusting screws I 14 abut against the two sides of the protrusion I 20 respectively. Under the action of external force, the rotary adjusting screws I 14 can apply a pushing force to the protrusion, causing the clamping part to rotate.

[0040] Two or more pitch adjusting screws 15 are provided along the length of the cross clamp 12; they are respectively screwed onto the cover plate 19, and the free ends of each pitch adjusting screw 15 abut against the upper surface of the cross clamp 12; under the action of external force, the pitch adjusting screw 15 applies a pushing force to the cross clamp, causing the cross clamp to rotate.

[0041] like Figure 4 As shown, the second adjusting seat 3 includes a support 32, a clamping part II 33, and a rotating adjusting screw II 34;

[0042] The support 32 has a through hole for mounting another laser 4 to be adjusted. The side wall has an opening along the length of the hole, and a locking screw is provided at the opening. The locking screw is used to hold the laser. The top of the support 32 is recessed to form a cavity.

[0043] The clamping part II33 is clamped on the top of the laser to be adjusted 4, and one end of it extends to form a protrusion II35; the clamping part II33 is disposed in the cavity;

[0044] Two rotating adjusting screws II34 are provided, which are screwed onto the side wall of the cavity respectively. The free ends of the two rotating adjusting screws II34 abut against the two sides of the protrusion II35 respectively. Under the action of external force, the rotating adjusting screws II34 can apply a pushing force to the protrusion II, driving the clamping part II to rotate.

[0045] To achieve uniform force application, two pitch adjustment screws 15 are provided at one end of the cross clamp 12 along its width. The pitch adjustment screws 15 are used to fine-tune the pitch angle of the laser.

[0046] In a specific implementation, it also includes a linear screw slide 5, with the first adjusting seat 1 and / or the second adjusting seat 3 disposed on the slider of the linear screw slide 5.

[0047] The linear lead screw slide 5 is used to achieve its linear motion and change the position of the laser to be adjusted.

[0048] Both ends of the support rod 6 are inclined inward at 20°~60°. The upright plate 18 is L-shaped, and the wider side of the upright plate 18 is connected to the cover plate 19.

[0049] To facilitate operator adjustments, the relationship between the rotation angle and feed rate of the rotary adjustment screws I 14, I 15, and II 34 is marked on their respective installation positions. That is, it indicates to the operator how many angles the laser rotates by rotating one full turn of the screw.

[0050] For example, using an M3×0.5 screw (0.5 refers to the screw pitch), rotating it 1 turn results in a feed of 0.5mm. Using the arc length formula: L=(n×π×r) / 180, we can derive the central angle n=(180L) / (πr), which means the laser rotated by 0.03 degrees.

[0051] In practice, a 360° circumferential angle scale ring can be provided on the coaxial circumferential direction at the installation positions of the rotary adjustment screw I14, the pitch adjustment screw 15, and the rotary adjustment screw II34.

[0052] The adjustment range of this structure has precise data for reference, resulting in high efficiency. Furthermore, after adjustment, the relevant tooling does not need to be disassembled and can be directly put into use with the laser, avoiding the influence of external factors.

[0053] The foregoing description of specific exemplary embodiments of this testing system is for illustrative and descriptive purposes.
