Description

Technical Field

[0001] This utility model belongs to the field of laser installation technology, specifically relating to a coaxial adjustment device for lasers. Background Technology

[0002] Laser tubes, due to their simple structure and superior performance, are widely used in scientific research, medical treatment, and industrial processing. They typically employ DC discharge excitation or radio frequency excitation to generate a laser beam through resonant cavity oscillation. However, the resonant cavity and water-cooling structure of current laser tubes are made of borosilicate glass, which is susceptible to damage from external impacts, and there are no alternative materials. Once subjected to external impact, the size and shape of the laser spot, the coaxiality of the beam emission position, and the laser power will all undergo irreversible changes. Therefore, the design and installation of coaxial adjustment and shock absorption protection for laser tubes are the most crucial and critical aspects of their use, and also the direct basis for determining whether a laser tube can be used in high-precision, high-requirement manufacturing fields.

[0003] Existing lasers are mainly fixed by sponge-like cushioning materials and tape or double-sided tape, which makes laser positioning inconvenient, prone to displacement during transportation, and risk of collision damage; the coaxial adjustment of the laser is also inconvenient. Summary of the Invention

Under the premise of ensuring the overall structural strength, a self-aligning mechanism is added to the structure to adjust the coaxiality between the laser's output port and the light transmission aperture, ensuring the positioning of the laser. Furthermore, a circular protective cover structure is added to the outer shell to increase the overall strength and related protective performance of the device. It has the advantages of convenient coaxiality adjustment, simple disassembly and assembly, and protection against impacts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coaxial adjustment device for a laser, comprising a laser and a front support base.

A frustum positioning part is set on the adapter to engage with the positioning hole on the front support, facilitating quick disassembly and maintenance of the laser.

[0008] A number of connecting posts are provided between the adapter and the tail support to slide and connect the self-aligning mechanism. The self-aligning mechanism is provided with a locking element to cooperate with the connecting posts to lock the position of the retainer and realize the positioning of the laser.

[0009] Furthermore, the retainer is provided with a plurality of crossbeam sleeves, which are slidably fitted onto the connecting column. The locking element includes a locking nut for clamping the crossbeam sleeves inward, and the locking nut is screwed onto the outer ring of the crossbeam sleeve.

[0011] Furthermore, the retainer has a ring structure, and the locking element includes a locking screw screwed onto the retainer, the locking screw being used to engage with the connecting rod.

[0012] The cage is screwed with a locking screw, which, in conjunction with the connecting rod, enables the cage to be positioned axially.

[0013] Furthermore, the self-aligning spacer includes spacer unit one and spacer unit two arranged opposite to each other, and spacer unit one and spacer unit two are connected by fastener one.

[0014] The spacer unit 1 and spacer unit 2 are connected by fastener 1 to cooperate with the shock-absorbing pad layer, which facilitates the adjustment of the laser direction by the self-aligning set screw.

[0015] Furthermore, the connecting mechanism includes a protective tube, the retainer is fixed on the protective tube, and the protective tube has a self-aligning hole, the position of which corresponds to the self-aligning set screw.

[0016] The protective tube is connected to the adapter and the tail support at both ends, respectively. The retainer is fixed by the protective tube, and the self-aligning hole is opened on the protective tube to facilitate the adjustment of the self-aligning screw.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] 1. This solution uses a self-aligning mechanism to adjust the laser and achieve the coaxiality requirement of the output port. The self-aligning set screw and self-aligning spacer are used to fix and adjust the direction and position of the laser. By increasing the number and size of the self-aligning mechanism, it can be applied to lasers of different sizes to achieve the fixing and coaxial adjustment requirements of glass lasers. The coaxiality adjustment is convenient.

[0025] 2. This solution uses the engagement of the frustum positioning part of the adapter with the front support base to position the laser front end, which simplifies disassembly and maintenance;

[0026] 3. For scenarios where the device needs both excellent strength and light weight, a solution using carbon fiber protective tubes is proposed.

Example 1

[0038] like Figure 1-5 As shown, a coaxial adjustment device for a laser includes a laser 1 and a front support 11. A shock-absorbing pad 17 is provided around the outer ring of the laser 1, and a self-aligning spacer is provided around the outer ring of the shock-absorbing pad 17. An adapter 8 is provided on the front side of the laser 1, and a frustum positioning part 21 for engaging with the front support 11 is provided on the adapter 8. An output slot 20 for engaging with the output port of the laser 1 is provided on both the adapter 8 and the front support 11. A tail support 2 is provided on the rear side of the laser 1. A connecting mechanism is provided between the adapter 8 and the tail support 2, and the connecting mechanism is connected to a self-aligning mechanism. The self-aligning mechanism includes a retainer 5 located around the outer ring of the laser 1, and a plurality of self-aligning set screws 15 are screwed onto the retainer 5. The inner ends of the plurality of self-aligning set screws 15 engage with the outer ring of the self-aligning spacer.

[0039] In the above scheme, a shock-absorbing pad 17 and a self-aligning spacer are provided on the outer ring of the laser 1. The shock-absorbing pad 17 is made of flexible material to reduce the rigid impact on the laser 1. A connecting mechanism is provided to position the self-aligning mechanism. The self-aligning mechanism's retainer 5 is provided with a self-aligning set screw 15 to adjust and position the self-aligning spacer, thereby achieving the positioning of the laser 1. A frustum positioning part 21 is provided on the adapter 8 to engage with the positioning hole on the front support 11, which facilitates the quick disassembly and maintenance of the laser 1. An exit hole slot 20 is provided on the adapter 8 and the front support 11 to allow the laser to pass through the exit hole.

[0040] Fastener 1 (24), Fastener 2, and Fastener 3 (12) include screws.

[0041] The proposed coaxial adjustment device for laser 1 includes a connecting column 4, a self-aligning mechanism, an adapter 8, a front support 11, and a rear support 2. It is used to solve the problems of inconvenient coaxial adjustment and circumferential fixing of laser 1, as well as the problem of shock absorption and coaxial adjustment after oscillation and displacement of laser 1 during movement.

[0042] like Figure 1 As shown, Figure 1 The outer protective tube 16 is omitted in this solution. The four connecting columns 4 are fixed by the flange 3 and the adapter 8 to form a circumferential protective structure around the laser 1. At the same time, the self-aligning mechanism is fixed on the four connecting columns 4 to form an overall optical cage system structure. The self-aligning mechanism has a silicone pad or rubber pad as a shock-absorbing pad layer 17 that contacts the laser 1 to achieve coaxial connection and concentric adjustment of the laser 1, thereby realizing the protection and shock absorption function of the laser 1.

[0043] First, the number of overall alignment mechanisms is determined based on the size and specifications of laser 1. This results in four connecting posts 4 and three alignment mechanisms, achieving the optimal configuration achievable with current technology. Key component parameters for this solution are as follows:

[0044] Laser 1 has the following specific parameters: wavelength: 10600nm, power: 50-500W. Alignment mechanism: optical cage system frame fixing structure.

[0045] Let's take a 300W laser as an example:

[0046] A 10600nm wavelength laser 1, with a laser beam diameter of 7mm, is first secured to four connecting posts 4 via the post holes on the adapter 8, ensuring the connecting posts 4 are horizontally fixed. A self-aligning retainer 5 is mounted on each connecting post 4, sliding back and forth on a support rod via a crossbeam sleeve 6. Four self-aligning screws 15 are distributed at 90° intervals along the circumference of the retainer 5, allowing for concentricity adjustment in four directions. The axial position of the retainer 5 on the connecting rod is secured by a locking device. Rubber pads are wrapped around the outer glass wall of the laser 1, evenly distributed front and back, and wrapped a total of three times. The laser 1 is fixed to the rubber pads by spacer units 13 and 14, which are connected by screws to prevent the laser 1 from sliding back and forth. Finally, the laser 1 is inserted into the connecting column 4, and the positions of the retainer 5 and the laser 1 are moved so that the axial positions of the retainer 5 and the self-aligning spacer coincide. The self-aligning spacer is then circumferentially fixed by the self-aligning set screw 15, thus forming a complete self-aligning mechanism. The whole structure forms an optical cage system, and the coaxial offset of the laser 1 is controlled by adjusting the depth of the upper, lower, left, and right set screws. The whole system achieves the effect of ring suspension locking protection, shock absorption, and buffering while allowing for coaxial adjustment.

[0047] The specific workflow is as follows:

[0048] like Figure 3 As shown, laser 1 is connected to spacer unit 13 and spacer unit 14 at the rubber pad. The self-aligning spacer, through self-aligning screws 15 and retainer 5, positions laser 1 within the self-aligning mechanism. The retainer 5 is equipped with four self-aligning screws 15 distributed 90° around the circumference, allowing for concentricity adjustment in four directions. The retainer 5 can slide axially on the connecting column 4 via the crossbeam sleeve 6. The self-aligning mechanism is fixed to the moving position on the connecting column 4 via the crossbeam sleeve 6 and locking nut 7. The remaining two self-aligning mechanisms are then installed and fixed in their designated positions. This ensures that the entire laser 1 is enclosed by the connecting column 4, achieving a protective and shock-absorbing effect. Finally, the self-aligning screws 15 near the front end of laser 1 are adjusted. The specific operation procedure is as follows: First, adjust the screws on the left and right sides to observe the positional offset of the light output port. Then adjust the screws on the other side. Next, adjust the screws on the top side to observe the positional offset of the light output port, and then adjust the screws on the bottom side. The cage 5 and the self-aligning spacer are circumferentially fixed by the self-aligning top screw 15, forming an optical cage system structure to achieve coaxial adjustment. Together with the shock-absorbing pad 17 and the protective tube 18, it achieves the effects of ring suspension locking protection and shock absorption.

[0049] Furthermore, the connecting mechanism includes a plurality of connecting posts 4, on which the self-aligning mechanism is slidably disposed, and the self-aligning mechanism is provided with a locking element for cooperating with the connecting posts 4.

[0050] A plurality of connecting posts 4 are provided between the adapter 8 and the tail support 2 to slide and connect the self-aligning mechanism. The self-aligning mechanism is provided with a locking element to cooperate with the connecting posts 4 to lock the position of the retainer 5, thereby achieving the positioning of the laser 1. The retainer 5 is a ring structure.

[0051] Furthermore, the retainer 5 is provided with a plurality of crossbeam sleeves 6, which are slidably sleeved on the connecting column 4. The locking member includes a locking nut 7 for clamping the crossbeam sleeves 6 inward, and the locking nut 7 is screwed onto the outer ring of the crossbeam sleeves 6.

[0052] The crossbeam sleeve 6 is set to slide with the connecting column 4, and the crossbeam sleeve 6 is clamped inward to the connecting column 4 by rotating the locking nut 7, thereby achieving the axial positioning of the cage 5.

[0053] The crossbeam sleeve 6 is fixed or integrally set with the retainer 5. The end of the crossbeam sleeve 6 has a tapered structure, preferably containing multiple tapered clamping plates. The locking nut 7 includes an inclined surface for engaging with the outer side of the clamping plates.

[0054] Furthermore, the self-aligning spacer includes a spacer unit 13 and a spacer unit 24 disposed opposite to each other, and the spacer unit 13 and the spacer unit 24 are connected by a fastener 24.

[0055] The spacer unit 13 and spacer unit 14 are connected by fastener 124 to cooperate with the shock-absorbing pad 17, which facilitates the adjustment of the laser 1 direction by the self-aligning screw 15.

[0056] Furthermore, the front support 11 and the rear support 2 are provided with mounting holes for connecting the second fastener.

[0057] Fastener 2 is connected by opening mounting holes, and the front support 11 and the rear support 2 are connected and fixed by fastener 2.

[0058] Furthermore, the front support 11 is connected to the galvanometer assembly 10 via a connector, and the light inlet of the galvanometer assembly 10 corresponds to the position of the light outlet slot 20.

[0059] The galvanometer assembly 10 is connected via connectors, making installation and maintenance convenient. The light inlet of the galvanometer assembly 10 corresponds to the light outlet slot 20 to conduct the laser emitted by the laser 1.

[0060] The connector includes a galvanometer connecting plate 9, and the two sides of the galvanometer connecting plate 9 are connected to the galvanometer assembly 10 and the front support base 11 by screws, respectively.

[0061] Furthermore, the adapter 8 and the tail support 2 are connected by a fastener 312 to an outer protective tube 16, and the connecting post 4 is located in the middle of the outer protective tube 16.

[0062] Fastener 312 is used to connect the two ends of the outer protective tube 16, and the outer protective tube 16 is used to protect the internal laser 1.

[0063] The outer protective tube 16 is a cylindrical structure. The tail support 2 includes an annular bracket and a flange 3 connected to the annular bracket. The adapter 8 and the flange 3 are connected to both ends of the outer protective tube 16. The whole tube wraps around the laser 1 to achieve the effect of protection and solve the problem that the laser 1 is easily bumped.

[0064] When this solution is applied to practical needs, multiple coaxial adjustment devices can be combined and arranged side by side and suspended on a load trolley to achieve the effect of moving the light source to process the entire surface. Example 2

[0066] Furthermore, the locking element includes a locking screw 22 screwed onto the retainer 5, the locking screw 22 being used to engage with the connecting rod.

[0067] The cage 5 is screwed with a locking screw 22, which, in conjunction with the connecting rod, enables the cage 5 to be positioned axially. Example 3

[0068] like Figure 7-8 As shown, Figure 8 The protective tube 18 is omitted. The coaxial adjustment device for a laser in this embodiment is further modified based on embodiment 1 as follows:

[0069] Considering the overall mass requirements of the device mounted on the load-moving platform, and the number of devices on the load, this embodiment proposes a solution using carbon fiber protective tubing 18 to reduce weight.

[0070] Carbon fiber protective tube 18 and carbon fiber connecting column 4 are used as the main support and protection structure. The connecting column 4 and locking components are removed. The protective tube 18 is used to position the cage 5. The high strength of carbon fiber is used to ensure the rigidity of the overall laser 1 and to make related coaxial adjustments. While meeting the strength requirements, it is also lightweight, which facilitates the movement of the entire device and its movement on a vehicle.

[0071] Furthermore, the connecting mechanism includes a protective tube 18, the retainer 5 is fixed on the protective tube 18, and the protective tube 18 has a self-aligning hole 23, the position of which corresponds to the self-aligning set screw 15.
