[0034] It should be understood that the term “and / or” used in the present specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0036] See also Figure 1 and Figure 2 An embodiment of the utility model provides a laser detection device 100, comprising a detection member 10, a base 50, a laser support 30 and an adjustment assembly 40. The detection member 10 is used to detect the laser of the laser. The laser support 30 is provided on the base 50, and the laser support 30 is provided with a receiving groove 31, and the receiving groove 31 is used to limit the laser. The adjustment assembly 40 is slidably connected to the base 50 along a first direction to move in a direction close to or away from the laser support 30. The detection member 10 is provided on the adjustment assembly 40, and the adjustment assembly 40 includes a first adjustment member 41, and the first adjustment member 41 is used to adjust the position of the detection member 10 along a second direction, and the second direction is perpendicular to the first direction.

[0037] In an embodiment of the present invention, the adjustment component 40 drives the detection component 10 to move along the first direction, that is, the distance between the detection component 10 and the laser provided on the laser support 30 is increased or decreased, so as to facilitate observation of the concentricity offset of the laser through the detection component 10, thereby providing a basis for adjusting the concentricity of the laser; in addition, the adjustment component 40 can also adjust the position of the detection component 10 along the second direction to compensate for installation errors, production errors, etc., to ensure that the detection component 10 and the laser of the laser can be coaxial to a certain extent.

[0038] Specifically, the detection part 10 may include an optical sensor to measure the laser. The detection part 10 may also include a scale plate 13 to facilitate the user to observe the concentricity of the laser with the naked eye. The detection part 10 only needs to be able to detect the laser concentricity offset. This application does not impose any specific restrictions on the structure of the detection part 10.

[0039] The laser support 30 is used to support the position-limiting laser. It is understandable that the accommodating groove 31 is used to accommodate the position-limiting laser. The shape of the accommodating groove 31 can be adjusted according to the shape and size of the laser, and this application does not impose any specific restrictions.

[0040] The adjustment component 40 is used to drive the detection member 10 to move along the first direction. The adjustment component 40 can also fine-tune the position of the detection member 10 along the second direction so that the detection member 10 is coaxial with the laser of the laser. It can be understood that the second direction can be a horizontal direction, and the second direction can also be a vertical direction. This application does not impose specific restrictions. There are many structures of the first adjustment member 41. The first adjustment member 41 can include a gasket, and the position of the detection member 10 along the second direction can be fine-tuned by adding or reducing the gasket; the first adjustment member 41 can include a screw, and the position of the detection member 10 along the second direction can be adjusted by turning the screw. There are many other structures of the first adjustment member 41, and this application will not list them one by one.

[0041] See also Figures 2 to 4 In the embodiment of the present utility model, the first adjusting member 41 includes a first adjusting knob 411, a first fixing member 413, a rotating member 415 and a first connecting member 416. The first adjusting knob 411 is penetrated by the first fixing member 413 in a direction perpendicular to the second direction. The first adjusting knob 411 is threadedly connected to the first fixing member 413. The rotating member 415 is rotatably connected to the first fixing member 413. One side of the rotating member 415 abuts against one end of the first adjusting knob 411, and the other side of the rotating member 415 abuts against the first connecting member 416. The first connecting member 416 moves along the second direction under the drive of the rotating member 415, and the detection member 10 is arranged on the first connecting member 416.

[0042] In this way, by turning the first adjusting knob 411, the first adjusting knob 411 can be controlled to extend or shorten relative to the first fixing member 413, so that the rotating member 415 abutting against the first adjusting knob 411 rotates, and the rotating member 415 converts the displacement of the first adjusting knob 411 perpendicular to the second direction into a displacement along the second direction to adjust the position of the first connecting member 416 in the second direction, thereby adjusting the position of the detection member 10 connected to the first connecting member 416 along the second direction.

[0043] It can be understood that the direction perpendicular to the second direction can be the first direction or other directions perpendicular to the second direction, and this application does not impose any specific limitation.

[0044] Since the first adjusting knob 411 is threadedly connected to the first fixing member 413 , the first adjusting knob 411 can move relative to the first fixing member 413 when rotating, thereby enabling the first adjusting knob 411 to be extended and retracted.

[0045] It is worth noting that when the second direction is a vertical direction, the first connecting member 416 and the rotating member 415 can maintain contact with each other under the action of gravity, and the rotating member 415 and the first adjusting knob 411 can also maintain contact with each other under the action of the component force of gravity; when the second direction is a horizontal direction, the rotating member 415 and the first connecting member 416 and the first adjusting knob 411 can maintain contact with each other through magnetic force, and an elastic member can also be provided between the rotating member 415 and the first connecting member 416 and the first adjusting knob 411 to maintain contact between the rotating member 415 and the first connecting member 416 and the first adjusting knob 411, which are not listed one by one in this application.

[0046] For further information, see Figures 2 to 4 The first adjusting member 41 further includes a first sliding limiter 417 , which is slidably connected to the first fixing member 413 along the second direction, and the first connecting member 416 is disposed on the first sliding limiter 417 .

[0047] In this way, the first sliding limiter 417 can limit and guide the first connecting member 416 to avoid the poor detection effect of the detecting member 10 caused by the shaking of the first connecting member 416.

[0048] It can be understood that there are many ways to connect the first sliding limit member 417 and the first fixed member 413 in a sliding manner along the second direction. The first sliding limit member 417 can be provided with a sliding rail and the first fixed member 413 can be provided with a matching slider, or the first sliding limit member 417 can be provided with a slider and the first fixed member 413 can be provided with a sliding rail. This application does not specifically limit this.

[0049] For further information, see Figures 2 to 4The end of the first adjusting knob 411 that abuts the rotating member 415 is semicircular, and the position where the first connecting member 416 abuts the rotating member 415 is semicircular. The rotating member 415 includes a main body 4151 and two semi-cylindrical protrusions 4153. The two semi-cylindrical protrusions 4153 are respectively arranged in directions perpendicular to the second direction. The two semi-cylindrical protrusions 4153 are arranged on both sides of the main body 4151 and abut against the first adjusting knob 411 and the first connecting member 416 respectively.

[0050] In this way, since the end of the first adjusting knob 411 that abuts against the rotating member 415 is semicircular, and the side of the rotating member 415 that abuts against the first adjusting knob 411 is semi-cylindrical, the contact area between the first adjusting knob 411 and the rotating member 415 is effectively reduced, and the friction force when the first adjusting knob 411 rotates relative to the rotating member 415 is reduced, making it easier for the first adjusting knob 411 to adjust the angle of the rotating member 415. In addition, as the rotating member 415 rotates, the abutting position of the first adjusting knob 411 and the rotating member 415 will also There are slight changes, which reduce friction and facilitate the rotation of the rotating member 415; since the end of the first connecting member 416 that abuts the rotating member 415 is semicircular, and the side of the rotating member 415 that abuts the first connecting member 416 is also semi-cylindrical, it can also effectively reduce the contact area between the first connecting member 416 and the rotating member 415, thereby reducing the friction between the first connecting member 416 and the rotating member 415, and facilitating the change of the abutment position between the rotating member 415 and the first connecting member 416 during the rotation of the rotating member 415.

[0051] It can be understood that in other embodiments, the rotating member 415 may include a semi-cylindrical protrusion 4153, the main body 4151 may be abutted against the first connecting member 416 through the above-mentioned semi-cylindrical protrusion 4153, or the main body 4151 may be connected to the first adjustment knob 411 through the above-mentioned semi-cylindrical protrusion 4153. This application does not impose any specific restrictions.

[0052] See also Figure 4 In an embodiment of the present invention, the first adjusting member 41 also includes an auxiliary limiting member 418 and a connecting bolt 419. The auxiliary limiting member 418 is connected to the first fixing member 413. The auxiliary limiting member 418 is provided with a waist-shaped hole 4181 extending along the second direction. The connecting bolt 419 is passed through the waist-shaped hole 4181 and is bolted to the first sliding limiting member 417.

[0053] In this way, after the position adjustment of the first connecting member 416 along the second direction is completed, the auxiliary limiting member 418 can cooperate with the connecting bolt 419 to limit the relative position relationship between the first sliding limiting member 417 and the first fixed member 413, thereby limiting the movement of the first connecting member 416 along the second direction, reducing the probability of shaking of the first connecting member 416, and further limiting the first connecting member 416.

[0054] It can be understood that there are many ways to connect the auxiliary limiting member 418 to the first fixing member 413. The auxiliary limiting member 418 and the first fixing member 413 can be fixedly connected by welding, bonding, etc., or the auxiliary limiting member 418 and the first fixing member 413 can be detachably connected by screw connection, snap connection, etc., or the auxiliary limiting member 418 and the first fixing member 413 can be integrally formed. This application does not impose any specific restrictions.

[0055] See also Figures 1 to 4 In an embodiment of the present invention, the adjustment component 40 further includes a second adjustment member 43, which is used to adjust the position of the detection member 10 along the third direction. The third direction, the first direction, and the second direction are perpendicular to each other.

[0056] In this way, the adjustment component 40 further adjusts the position of the detection member 10 along the third direction, effectively compensating for installation errors, production errors, etc., and ensuring that the detection member 10 can be coaxial with the laser light of the laser.

[0057] It is understood that the second direction can be vertical and the third direction can be horizontal; the second direction can also be horizontal and the third direction can also be vertical, and this application does not impose specific limitations. Because the detection member 10 can move in the first, second, and third directions, respectively, the detection member 10 can achieve three-axis adjustment, effectively compensating for production errors and installation errors in different directions.

[0058] For details, please refer to Figures 1 to 4 The second adjusting member 43 includes a second adjusting knob 431, a second fixing member 433 and a second connecting member 435. The second adjusting knob 431 passes through the second fixing member 433 along the third direction. The second adjusting knob 431 is threadedly connected to the second fixing member 433. One end of the second adjusting knob 431 abuts against the second connecting member 435. The second connecting member 435 is also slidably connected to the second fixing member 433 along the third direction. The detection member 10 is arranged on the second connecting member 435.

[0059] In this way, the second adjusting knob 431 can be turned to extend or retract relative to the second fixing member 433, thereby adjusting the relative position relationship between the second connecting member 435 and the second fixing member 433, thereby adjusting the position of the detection member 10 along the third direction.

[0060] It can be understood that the detection member 10 can be directly provided on the second connecting member 435, that is, the detection member 10 is directly connected to the second connecting member 435, and the second adjusting member 43 is provided on the first adjusting member 41; the detection member 10 can also be indirectly provided on the second connecting member 435, that is, the detection member 10 is directly connected to the first adjusting member 41, and the first adjusting member 41 is provided on the second adjusting member 43. This application does not make specific restrictions.

[0061] See also Figure 1 and Figure 2 In the embodiment of the present invention, the detection part 10 includes a penetration plate 11 and a scale plate 13. The penetration plate 11 is provided with a laser through hole 111, and the scale plate 13 is provided with a scale. In the direction away from the laser support 30, the penetration plate 11 and the scale plate 13 are arranged in sequence at intervals.

[0062] In this way, the laser passes through the laser through hole 111 and is emitted onto the scale plate 13. The position of the detection component 10 is adjusted according to the scale on the scale plate 13, which not only detects the concentricity of the laser, but also calculates the divergence angle of the laser, making it convenient to use and adjust the laser.

[0063] See also Figure 1 In an embodiment of the present invention, the laser detection device 100 further includes a slide rail 20, the laser support 30 and the slide rail 20 are sequentially arranged on the base 50 along a first direction, and the adjustment assembly 40 is slidably connected to the slide rail 20 along the first direction.

[0064] In this way, the adjustment assembly 40 is slidably connected to the base 50 along the first direction.
