[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model provides a laser detector for the smoothness of comb teeth, including a detection platform 1, a detection frame 3 installed on the top of the detection platform 1, a laser detector body 4 installed on the lower inner wall of the detection frame 3, two electric slide rails 2 fixedly connected to the top of the detection platform 1, and a fixed platform 5 slidably connected to the outer surface of the two electric slide rails 2. Through the cooperation of the detection platform 1, the electric slide rails 2 and the fixed platform 5, the detection position of the comb can be precisely adjusted. The top of the fixed platform 5 is provided with four fixing components 6.

[0026] The fixing component 6 includes a receiving groove 61 opened at the top of the fixing platform 5. The inner walls on both sides of the receiving groove 61 are fixedly connected to a slide rod 63. The outer surface of the slide rod 63 is slidably connected to a clamping block 64, and the clamping block 64 is slidably connected to the receiving groove 61. A return spring 62 is wound around the outer surface of the slide rod 63. The return spring 62 is located between the clamping block 64 and one inner wall of the receiving groove 61. The slide rod 63, the clamping block 64 and the return spring 62 form a basic clamping structure, which provides stable support and initial fixation for the comb, ensuring that the laser detector body 4 can accurately align with the detection area, and at the same time, the device can fix combs of different sizes.

[0027] Specifically, the two ends of the return spring 62 abut against the inner wall of the clamping block 64 and the receiving groove 61 respectively. The two ends of the return spring 62 directly abut against the inner wall of the clamping block 64 and the receiving groove 61, eliminating the force deviation caused by the spring installation gap, making the clamping block 64 slide along the slide rod 63 with uniform force, making the clamping and reset actions more stable, and improving the reliability and service life of the basic clamping structure.

[0028] like Figures 1 to 5As shown, the top of the fixed platform 5 is provided with a placement groove 51. Four clamping blocks 64 are symmetrically distributed in pairs with the placement groove 51 as the axis of symmetry. The clamping ends of the four clamping blocks 64 are all fixedly connected with protective soft pads 641. The placement groove 51 can quickly position the comb and avoid placement deviation. The four symmetrically distributed clamping blocks 64 can clamp the comb from both sides in all directions. With the protective soft pads 641, it can adapt to different sizes of combs and avoid scratching the surface of the comb during clamping, achieving flexible and precise clamping, and improving the adaptability and safety of the equipment.

[0029] Furthermore, the clamping block 64 includes two static locking blocks 642 fixedly connected to it. The two static locking blocks 642 are arranged in a mirror image. The bottom end of the static locking block 642 is provided with an inclined surface 647. A movable locking block 643 is slidably connected to the inclined surface 647. The top end of the movable locking block 643 is provided with a mating surface 644 adapted to the inclined surface 647. The inclined surface 647 of the static locking block 642 and the mating surface 644 of the movable locking block 643 form a precise sliding adaptation structure. When the movable locking block 643 is manually pushed, the mating surface 644 slides smoothly along the inclined surface 647, which can convert the manual pushing force into a vertical downward displacement, guiding the movable locking block 643 to move precisely down to abut against the top of the fixed platform 5. This provides precise guidance and force support for manual locking operation, ensuring smooth locking action and accurate positioning.

[0030] like Figures 1 to 5 As shown, a guide groove 649 is provided on the inclined surface 647, and a guide block 645 is fixedly connected to the mating surface 644 to cooperate with the guide groove 649. The sliding cooperation between the guide block 645 and the guide groove 649 can strictly limit the movement trajectory of the moving locking block 643, effectively preventing the moving locking block 643 from shifting laterally or detaching from the inclined surface 647 during manual pushing, ensuring that the moving locking block 643 always moves vertically downward along the preset direction, further improving the accuracy and stability of manual locking operation.

[0031] It is worth noting that both the guide block 645 and the guide groove 649 have a "T" shaped cross section. The inner wall of the guide groove 649 away from the clamping block 64 is provided with magnetic coating 648. The guide block 645 is made of iron. The moving locking block 643 is provided with a locking rubber pad 646 at the position corresponding to the fixed platform 5. The "T" shaped cross section of the guide block 645 and the guide groove 649 can achieve bidirectional limiting to prevent them from separating. The magnetic attraction force formed by the magnetic coating 648 and the iron guide block 645 can provide initial positioning for the moving locking block 643 in the loose state, preventing it from shaking on its own. When locking, the manual pushing force can easily overcome the magnetic attraction force. After locking, the magnetic attraction force and the high friction of the locking rubber pad 646 work together to effectively resist the vibration of the equipment during the testing process and prevent the moving locking block 643 from loosening. This not only enhances the locking stability but also avoids the rigid collision between the moving locking block 643 and the fixed platform 5, extending the service life of the components.

[0032] Working principle and process: The comb to be tested is placed in the placement slot 51 of the fixed platform 5. The return spring 62 releases its elastic force, pushing the clamping block 64 to slide along the slide rod 63 and the receiving slot 61. The protective soft pad 641 achieves flexible clamping and initial fixation of the comb. Then, the moving locking block 643 is manually pushed so that its contact surface 644 slides along the inclined surface 647 of the stationary locking block 642. The guide block 645 guides precisely along the guide groove 649 and overcomes the magnetic attraction force of the magnetic coating 648, driving the moving locking block 643 to tilt. Move downwards until the locking rubber pad 646 is firmly abutting the top of the fixed platform 5, completing the reliable locking; activate the electric slide rail 2 to move the fixed platform 5 and the fixed comb smoothly to directly below the laser detector body 4. The laser detector body 4 emits a laser to irradiate the surface of the comb teeth, and obtains the smoothness parameters of the comb teeth by analyzing the reflected light data; after the test is completed, manually pull the moving locking block 643 so that the locking rubber pad 646 gradually moves away from the top of the fixed platform 5 to release the lock, and then remove the comb that has been tested.
