[0046] Figure 1 A schematic diagram showing the main structure of the adjustable laser testing device according to an embodiment of the present application is shown. Figure 2 A schematic side view showing the main structure of the adjustable laser testing device according to an embodiment of the present application, Figure 3 A schematic front view showing the main structure of the adjustable laser testing device according to an embodiment of the present application, Figure 4 A schematic top view of the main structure of the adjustable laser testing device according to an embodiment of the present application is shown. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjustable laser test device of the embodiment of the present application includes: a base plate 100, a slide rail 200 and a bearing 300. The base plate 100 is suitable for being placed on the top of the test platform, at least two slide rails 200 are slidably arranged on the top of the base plate 100, and at least two slide rails 200 can slide toward or away from each other, each slide rail 200 is provided with at least two bearings 300, the rotation direction of the bearing 300 is perpendicular to the length direction of the slide rail 200, and at least two slide rails 200 on each slide rail 200 can move toward or away from each other.

[0047] Therefore, by adjusting the distance between the two slide rails 200, lasers of different diameters can be adapted, and by adjusting the distance between the two bearings 300 on each slide rail 200, lasers of different lengths can be adapted. Specifically, the laser with a fixed sleeve is placed on four bearings 300, and can be rotated relative to the bearings 300 along the circumference of the laser, so as to test the laser. In addition, a limiter for the sliding of the slide rail 200 and the bearing 300 is provided on the laser testing device, so that the position of the slide rail 200 and the bearing 300 can be fixed to prevent the laser from slipping.

[0048] In a specific embodiment, the laser testing device further includes: two side panels 600, which are symmetrically arranged at the edge of the base plate 100 and located at both ends of the length direction of the slide rail 200, and are used to fix the slide rail 200 after the relative distance is determined.

[0049] Specifically, the length of the side plate 600 matches that of the bottom plate 100 , and the side plate 600 is fixed to the bottom plate 100 by using bolts.

[0050] Furthermore, in this specific embodiment, a plurality of first limiting holes 610 are provided on the surface of the base plate 100, and matching first fixing holes are provided at both ends of the length direction of the slide rail 200, and the length of the slide rail 200 is slightly smaller than the spacing distance between the two relative base plates 100, thereby ensuring that the slide rail 200 can slide between the two base plates 100.

[0051] When the slide rail 200 and the side wall are installed on the base plate 100 , the opening height of the first limiting hole 610 corresponds to the first fixing hole, and can be detachably fixed by using pins or bolts.

[0052] Furthermore, in this specific embodiment, the number of first limiting holes 610 is multiple and they are opened along the sliding direction of the slide rail 200. In this way, after adjusting the relative distance between the two slide rails 200, the slide rails 200 can be fixed at different positions on the side plate 600 by using pins to match lasers with different diameters.

[0053] In a specific embodiment, the laser test device further includes: a mounting frame, which is used to place the rotatable bearing 300 on the slide rail 200. The mounting frame includes: a mounting bracket 510 and a bearing pin 520. The bottom of the mounting bracket 510 can slide along the length direction of the slide rail 200, and the overall cross-section of the mounting bracket 510 is an inverted "T"-shaped structure, and a bearing pin mounting hole is opened in the middle for installing the bearing pin 520. The opening direction of the bearing pin mounting hole is the same as the length direction of the slide rail 200, so that the rotation direction of the bearing 300 module is perpendicular to the length direction of the slide rail 200, and the laser can be placed on four bearing 300 modules. The bearing pin 520 matches the bearing pin mounting hole, and the bearing pin 520 is set in the bearing pin mounting hole. The two ends pass through the bearing pin 520 and press the mounting hole, so that the bearing 300 can be rotatably set at any end of the bearing pin 520.

[0054] Specifically, the end of the bearing pin 520 facing the inner side of the bottom plate 100 is the bearing installation end, the bearing 300 is rotatably sleeved on the bearing installation end, and the end of the bearing pin 520 facing the outer side of the bottom plate 100 is the stopper installation end. In addition, a bearing 300 stopper is provided at the bearing installation end to limit the bearing 300.

[0055] In a specific embodiment, the mounting bracket 510 includes: a first bracket 511 and a second bracket 512, and the structure of the first bracket 511 is the same as that of the second bracket 512. The overall cross-section of the first bracket 511 is a "T"-shaped structure, including a mounting portion and a fixing portion connected at both ends and perpendicular to each other, and the mounting portion and the fixing portion are both in the shape of long strips, wherein a limiting groove is provided on a side wall where the mounting portion and the fixing portion are connected. The mounting portion of the first bracket 511 and the mounting portion of the second bracket 512 are connected by bolts to form a mounting bracket 510 with an overall cross-section in the shape of an inverted "T". Among them, the limiting grooves provided on the first bracket 511 and the second bracket 512 are in the same position and are used to install the bearing pin 520.

[0056] Furthermore, in this specific embodiment, the limiting groove runs through the first bracket 511 and the second bracket 512, and the cross section of the limiting groove is arc-shaped, which can match the bearing pin 520 and install the bearing pin 520 of the columnar structure. In addition, the cross-sectional arc of the limiting groove is 140 degrees, so after the first bracket 511 and the second bracket 512 are aligned and fixed with bolts, the limiting groove of the first bracket 511 and the limiting of the second bracket 512 can be combined into an ellipse. When the first bracket 511 and the second bracket 512 are separated by a certain distance, the limiting grooves of the first bracket 511 and the second bracket 512 can place a larger size of the bearing pin 520, thereby matching the specifications and sizes of more lasers.

[0057] Therefore, the splicing process of the mounting frame is as follows: align the first bracket 511 with the second bracket 512 to form an inverted "T"-shaped structure, and reserve a certain length of spacing distance between the first bracket 511 and the second bracket 512, then put the bearing pins 520 of different sizes between the limit grooves of the first bracket 511 and the second bracket 512, and finally fasten the first bracket 511 and the second bracket 512 with bolts.

[0058] In a specific embodiment, the laser testing device further includes: a bearing stopper 400. The stopper is a bearing structure, rotatably sleeved on the stopper mounting end of the bearing pin 520, located on the opposite side of the bearing 300, and the circumferential radius of the bearing stopper 400 is greater than the circumferential radius of the bearing 300.

[0059] Thus, the laser test device is placed on the detection platform, and the laser with the sleeve is placed on the four bearings 300 of the laser test device for rotation detection. Among them, the bearing 300 is rotatably arranged on the inner side of the mounting frame relative to the base plate 100, so that the laser can rotate in the horizontal direction. The bearing stopper 400 of the bearing 300 structure is rotatably arranged on the mounting frame and is located on the opposite side of the bearing 300, that is, the four bearing 300 modules are located on the inner side of the mounting frame, and the bearing stopper 400 of the four bearing 300 structures is located on the outer side of the mounting frame, and the circumferential radius of the bearing stopper 400 is greater than the circumferential radius of the bearing 300. When the two slide rails 200 slip off and slide back to back, the bearings 300 on the two slide rails 200 move back to back with the sliding of the slide rails 200, and the two ends of the laser located on the four bearings 300 will be located on the stopper with a larger circumferential radius, thereby preventing the laser from slipping off the bearing 300 and causing damage.

[0060] It should be noted that the laser is a cylindrical structure. Before the laser is detected, a sleeve is sleeved in the middle of the outer side of the laser machine. The sleeve has a hollow ring structure, which is convenient for rotating on four bearings 300 for detection. The sleeve has a certain thickness L. When the laser with the sleeve is placed on the bearing 300, the distance between the bearing 300 and the laser is the thickness L of the sleeve, and the circumferential radius difference I between the bearing limiter 400 and the bearing 300 module is slightly smaller than the sleeve thickness L. In this way, the open end of the sleeve with the laser is placed between the bearing 300 and the limiter of the mounting frame. When the slide rail 200 slides off and slides back to back, the laser will be directly located on the four bearing limiters 400 and will not fall off.

[0061] In a specific embodiment, the laser detector further includes: a first limiting portion. The first limiting portion is used to limit or fix the position of the bearing 300 on the slide rail 200. Specifically, two first limiting portions are sleeved on the slide rail 200 and are located on both sides of the rotation direction of the bearing 300. A plurality of second limiting holes are provided at the top of the slide rail 200 along the length direction, and the first limiting portion is provided with a second fixing hole adapted to the second limiting hole, so that the first limiting portion can be fixed on the slide rail 200 at a suitable position. In this way, according to the specifications of the laser, the positions of the two mounting frames provided with the bearing 300 on the slide rail 200 are adjusted on the slide rail 200 so that the laser can be properly installed.

[0062] In a specific embodiment, the laser testing device further includes: a second limiting portion 700, which can limit the slide rail 200 in the sliding direction and the vertical direction to prevent the slide rail 200 from slipping or tipping over. Specifically, the second limiting portion 700 includes a first blocking portion and a second blocking portion, and the first blocking portions are respectively arranged at both ends of the inner side of the side plate 600, so that the slide rail 200 is located between the two first limiting portions, so that the slide rail 200 can only slide on the bottom plate 100, and the slide rail 200 is prevented from slipping relative to the bottom plate 100. Two first blocking portions are arranged on the inner side of a side plate 600, and the two first blocking portions are respectively arranged at both ends of the side plate 600 relative to the slide rail 200, and the slide rail 200 between the two first limiting portions is limited to limit the sliding range of the slide rail 200 relative to the bottom plate 100. The second blocking portion is the same as the first blocking portion, both of which are long strip structures. The second blocking portion is arranged on the inner top of the side plate 600, along the length direction of the side plate 600, and above at least one end of the slide rail 200, to limit the slide rail 200 in the vertical direction to prevent the slide rail 200 from tipping over.

[0063] Therefore, there are two first blocking parts, which are respectively arranged at the two ends of the inner side of the side plate 600 in the length direction, and can limit the slide rail 200 in the sliding direction to prevent the slide rail 200 from sliding out of the bottom plate 100 of the plate-like structure. The second blocking part is arranged at the top of the inner side of the side plate 600, and can limit the slide rail 200 in the height direction to prevent the slide rail 200 of the test device from tipping over during the detection of the laser. The limiting structure combining the first blocking part and the second blocking part can limit in the vertical direction and the horizontal direction at the same time, ensuring that the slide rail 200 will not tip over and slide out of the bottom plate 100 during the detection of the laser test device.

[0064] Furthermore, in this specific embodiment, the first blocking portion is an elongated structure, which is arranged along the height direction of the side plate 600, so as to increase the contact area between the first blocking portion and the slide rail 200, reduce the force of the slide rail 200 when contacting the first blocking portion, and avoid damage to the slide rail 200. The two first blocking portions are symmetrically arranged on both sides of the length direction of the slide rail 200, and the two first blocking portions and the slide rail 200 are located in the same horizontal plane, so that the first blocking portions can limit the slide rail 200 in the horizontal direction. Among them, only two first limiting portions are needed to limit the slide rail 200 in the horizontal direction.

[0065] Furthermore, in this specific embodiment, the size of the laser is 1 / 3-1 / 2 of the length of the side plate 600, the length of the second blocking portion is 1 / 3 of the length of the side plate 600, and the two second blocking portions are arranged at both ends of the side plate 600, so as to ensure that the multiple second blocking portions can always limit the two ends of the slide rail 200. The inner sides of the two side plates 600 are provided with second blocking portions, so as to limit both ends of the slide rail 200, so as to prevent any end of the slide rail 200 from tipping over. The second blocking portion is located above any end of the slide rail 200, and the bottom of the second blocking portion is spaced from the top of the slide rail 200 by a preset distance, so as to ensure that the slide rail 200 will not contact and rub against the second blocking portion during the sliding process relative to the bottom plate 100. The preset distance between the second blocking portion and the slide rail 200 in the vertical direction is within the range of 1mm-2mm, so that the interval between the second blocking portion and any end of the slide rail 200 is so large that the slide rail 200 can be limited in the vertical direction.

[0066] Moreover, one end of the first blocking part in the length direction is connected to one end of the second blocking part in the length direction, and the first limiting part is perpendicular to the first blocking part, and the first blocking part and the second blocking part are integrally formed. The limiting structure composed of the first blocking part and the second blocking part is in a "﹃" shape, and is arranged at the corner position of the inner side of the side plate 600, and is aligned with the top and edge position of the side plate 600 respectively, and can simultaneously limit at least one end of the length direction of the slide rail 200 in the vertical direction and the horizontal direction to prevent the slide rail 200 from sliding out of the bottom plate 100 or tipping over. There are four limiting structures, which are respectively arranged at the corner positions of the inner sides of the two side plates 600, and the corner positions of the limiting structures can correspond to the corner positions of the side plates 600. The corner positions of the limiting structure and the corner positions of the side plates 600 are both rounded and corresponding. Improve the overall safety performance.

[0067] The second limiting portion 700 is made of plastic material, which has low rigidity, so that when the slide rail 200 contacts the limiting structure, the slide rail 200 is prevented from being damaged.

[0068] In a specific embodiment, two long strip-shaped first pads 120 are embedded on the top of the bottom plate 100. The two first pads 120 are arranged along the length direction of the side plate 600 and are parallel and perpendicular to the length direction of the slide rail 200. First sliders 220 are arranged at both ends of the length direction of the slide rail 200. The first sliders are located below the slide rail 200, so that the slide rail 200 slides on the first pads 120 through the first sliders 220.

[0069] Furthermore, in this specific embodiment, the distance between the two first pads 120 matches the length of the slide rail 200, and the first connection groove provided by the first slider 220 can be sleeved on the first pad 120 and slide along the length direction of the first pad 120, thereby avoiding direct friction between the slide rail 200 and the first pad 120 or the bottom plate 100, thereby extending the service life of the slide rail 200. In addition, the cross section of the first pad 120 is an inverted isosceles trapezoid, and the cross section of the first connection groove is a matching inverted isosceles trapezoid. The slide rail 200 provided with the first slider 220 passes through the two opposite first pads 120, further improving the stability of the installation of the slide rail 200.

[0070] In a specific embodiment, a second pad 210 is provided at the top of the slide rail 200 along the length direction, and the second pad 210 is a long strip structure, and a second slider 230 is provided at the bottom of the mounting frame. The second slider 230 is provided with a second connecting groove matching the second pad 210, so that the mounting frame can be slidably set on the slide rail 200 to avoid damage caused by friction between the mounting frame and the slide rail 200.

[0071] In a specific embodiment, when the laser is tested, the laser test device is placed on a flat optical test platform. A plurality of through holes arranged in an array are provided on the top of the optical test platform, and a plurality of matching third fixing holes 110 are provided on the bottom plate 100 of the laser test device, so that the laser test device can be fixed on the top of the optical test platform with bolts, ensuring that the laser test device will not shake when the laser is tested, thereby improving the accuracy of the laser test.

[0072] In a specific embodiment, two slide rails 200 are provided on the bottom plate 100 , which can hold at least one laser, and two rotatable bearings 300 are provided on each slide rail 200 , that is, it is best to test one laser each time.
