Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Embodiment 1

[0033] See also Figure 1-Figure 8 A linear guide rail flatness detection device comprises a detection platform 1, a detection guide rail 2 is arranged at the top of the detection platform 1; a detection mechanism is arranged at the top of the detection platform 1, and the detection mechanism is used to detect the flatness of the detection guide rail 2;

[0034] The detection mechanism includes a moving component, a height adjustment component, an adapter component, a fixed component and a precision adjustment component. The moving component includes a sliding rail 21 and a sliding block 22. The sliding rail 21 is fixedly connected to the top of the detection platform 1, and the sliding block 22 is slidably connected to the outer side of the sliding rail 21. A laser emitting module 23 is arranged at the top of the moving component, and a height adjustment component is arranged between the laser emitting module 23 and the moving component. An adapter component is arranged on the rear side of the moving component. A laser receiving module 37 is fixedly connected to the top of the adapter component, and a precision adjustment component is arranged at the front end of the laser receiving module 37. Both the laser emitting module 23 and the laser receiving module 37 are powered by batteries. An indicator light is electrically connected to the laser receiving module 37. When a laser is received, the indicator light remains off, and when no laser is received, the indicator light lights up.

[0035] Furthermore, the adapter assembly includes a movable groove 32, which is arranged at the rear side of the sliding block 22, and the interior of the movable groove 32 is fixedly connected with a first guide rod 33, and the outer side of the first guide rod 33 is slidably connected with a follower plate 34, and the rear side of the follower plate 34 is fixedly connected with a front adapter seat 35, and the adapter seat 35 is provided with two groups, and the two groups of adapter seats 35 are respectively fixedly connected to the front and rear ends of the bearing seat 36, and the top of the bearing seat 36 is fixedly connected with the laser receiving module 37, and the bottom end of the adapter seat 35 is provided with a movable groove 62, and the inner wall of the movable groove 62 is fixedly connected with a second guide rod 38, and the outer side of the second guide rod 38 is slidably connected with a moving block 39, and the outer side of the second guide rod 38 is wrapped with The bottom end of the tension spring 40 and the moving block 39 are fixedly connected to the adapter block 41, the bottom end of the adapter block 41 is provided with an inclined surface, and a lubricating gasket 42 is fixedly connected to the inclined surface provided at the bottom end of the adapter block 41, and the lubricating gasket 42 is made of nylon. The end of the tension spring 40 close to the moving block 39 is fixedly connected to the moving block 39, and the end of the tension spring 40 away from the moving block 39 is fixedly connected to the inner wall of the moving groove 62. The adapter block 41 is provided with a first rotating groove 43 on one side close to the detection guide rail 2, and a roller 44 is rotatably connected inside the first rotating groove 43, and the roller 44 is fitted with the outer side of the detection guide rail 2. The bottom end of the bearing seat 36 is rotatably connected to two sets of rotating wheels 45, and the rotating wheels 45 are fitted with the top of the detection guide rail 2.

[0036] During operation, when the flatness of the linear guide is to be detected, the laser receiving module 37 needs to be fixed on the detection guide 2 to be detected first. When fixing the laser receiving module 37, it is only necessary to align the bottom end of the bearing seat 36 with the detection guide 2 and then press the bearing seat 36 and the laser receiving module 37 toward the detection guide 2. Under the action of pressure, the two sides of the detection guide 2 will squeeze the lubricating gasket 42 made of nylon material glued to the adapter block 41, and the friction between the adapter block 41 and the outer side of the detection guide 2 is reduced by the lubricating gasket 42. Under the action of the inclined surface combination opened at the bottom of the adapter block 41, the adapter block 41 moves away from the detection guide 2 under the action of the squeezing force, and no longer blocks the detection guide 2. When moving, block 41 drives the fixedly connected moving block 39 to move synchronously inside the moving groove 62, and pulls the tension spring 40 to produce elastic deformation. When the top of the detection guide rail 2 contacts the rotating wheel 45 rotatably connected to the bottom of the supporting seat 36, the two sides of the detection guide rail 2 no longer push the adapter block 41 to continue moving. At this time, the adapter block 41 and the moving block 39 move to their original positions under the action of the restoring force of the tension spring 40, so that the roller 44 fits against the outer side of the detection guide rail 2, and the supporting seat 36 and the laser receiving module 37 are fixed on the outer side of the detection guide rail 2. Through the combined action of the roller 44 and the rotating wheel 45, the sliding friction between the supporting seat 36 and the adapter block 41 and the detection guide rail 2 is converted into rolling friction, thereby reducing the wear on the detection guide rail 2 when the detection guide rail 2 is detected.

[0037] Further, the height adjustment component includes an extension block 24, which is fixedly connected to the bottom end of the laser emitting module 23, and the extension block 24 is inserted into the interior of the storage chamber 25, and the storage chamber 25 is opened at the top of the sliding block 22. A first screw sleeve 26 is fixedly connected to the inner wall of the extension block 24, and the first screw sleeve 26 is threadedly connected to the first screw rod 27. The bottom end of the first screw rod 27 is rotatably connected to the inner wall of the storage chamber 25, and a worm gear 28 is fixedly connected to the outer side of the first screw rod 27 near the bottom end, and the worm gear 28 is meshed with the worm 29. The front end of the worm 29 penetrates the sliding block 22 and extends to the outside of the sliding block 22 and is fixedly connected to the knob 30, and the worm 29 is rotatably connected to the inner wall of the storage chamber 25;

[0038] During operation, after the bearing seat 36 and the laser receiving module 37 are fixed to the outer side of the detection guide rail 2, in order to match the height of the laser emitting module 23 with that of the laser receiving module 37, the height of the laser emitting module 23 needs to be adjusted. When adjusting the height of the laser emitting module 23, it is only necessary to rotate the knob 30 to drive the worm 29 fixedly connected to the knob 30 to rotate synchronously. The rotation of the worm 29 drives the meshing worm wheel 28 to rotate synchronously. The rotation of the worm wheel 28 drives the fixedly connected first screw 27 to rotate, so that the first screw sleeve 26 threadedly connected to the outer side of the first screw 27 is rotated. It moves up and down and drives the fixedly connected extension block 24 to move synchronously, thereby adjusting the height of the laser emitting module 23. When the laser emitting module 23 is adjusted to the specified height, stop turning the knob 30. The stopper 31 fixedly connected inside the storage cavity 25 limits the downward movement distance of the extension block 24, thereby avoiding friction between the inner wall of the extension block 24 and the top of the first screw 27, and friction between the bottom end of the extension block 24 and the worm gear 28. The self-locking characteristics of the worm gear 28 and the worm 29 prevent the extension block 24 from automatically falling back.

[0039] During operation, when the flatness of the detection guide rail 2 is to be detected, the sliding block 22 is pushed to drive the laser emitting module 23 and the laser receiving module 37 to move synchronously. When there are protrusions or pits on the surface of the detection guide rail 2, the bearing seat 36 and the laser receiving module 37 will float up and down with the protrusions and pits. If the pits and protrusions are within the allowed range, the laser receiving module 37 can always receive the laser emitted by the laser emitting module 23. If the protrusions or pits are large, the laser receiving module 37 will not be able to receive the laser emitted by the laser emitting module 23 due to the large up and down floating distance, resulting in signal disconnection. The flatness of the detection guide rail 2 can be conveniently and quickly evaluated according to the number of times the laser receiving module 37 signal is disconnected in a single detection. When the laser receiving module 37 floats up and down, the adapter seat 35 drives the follower plate 34 to slide synchronously inside the active groove 32. The active groove 32 and the first guide rod 33 cooperate to enable the laser receiving module 37 and the laser emitting module 23 to maintain longitudinal freedom during the synchronous lateral movement.

[0040] Further, the fixed assembly includes a fixed baffle 46 and a movable baffle 47, the fixed baffle 46 is fixedly connected to the top of the detection platform 1, the movable baffle 47 is also arranged on the top of the detection platform 1, the bottom end of the movable baffle 47 is fixedly connected with a second screw sleeve 49, the second screw sleeve 49 is threadedly connected to the outside of the second screw rod 50, the second screw rod 50 is rotatably connected to the inner wall of the movable cavity 51, the movable cavity 51 is opened at the center position of the top of the detection platform 1 near the rear side, the rear end of the second screw rod 50 penetrates the detection platform 1 and extends to the outside of the detection platform 1 and is fixedly connected to the rotating button 52, the movable baffle 47 and the fixed baffle 46 are fixedly connected to the side of the detection guide rail 2 with an anti-skid pad 48, and the anti-skid pad 48 is made of rubber;

[0041] During operation, when the detection guide rail 2 is to be fixed, first one side of the detection guide rail 2 is fitted with the fixed baffle 46, and then the rotating button 52 is turned to drive the fixedly connected second screw 50 to rotate synchronously, so that the second screw 50 drives the threadedly connected second screw sleeve 49 to move, and then the movable baffle 47 fixedly connected to the second screw sleeve 49 is made close to the other side of the detection guide rail 2, and the detection guide rail 2 is clamped and fixed by the cooperation of the movable baffle 47 and the fixed baffle 46, and the anti-slip pad 48 made of rubber material glued on the movable baffle 47 and the fixed baffle 46 protects the outer side of the detection guide rail 2 while increasing the friction, thereby preventing the detection guide rail 2 from sliding during the detection process.

[0042] Furthermore, the precision adjustment component includes a receiving lens 61, which is fixedly connected to the front end of the laser receiving module 37, and a second rotating groove 60 is provided on the outer side of the front end of the receiving lens 61, and the second rotating groove 60 is rotatably connected to the rotating ring 59, and the rotating ring 59 is fixedly connected to the inner wall of the rotating plate 53. The inner wall of the rotating plate 53 is also provided with six groups of first slide grooves 54, and the interiors of the six groups of first slide grooves 54 are all slidably connected with one end of a slider 55, and the slider 55 is fixedly connected to the shielding baffle 56, and the other end of the slider 55 is slidably connected to the interior of the second slide groove 57, and the second slide groove 57 is designed in a regular hexagon, and the second slide groove 57 is provided on the bearing plate 58, and the bearing plate 58 is fixedly connected to the front end of the receiving lens 61. When detecting detection guide rails 2 of different specifications, , it is necessary to adjust the detection accuracy according to different requirements. When adjusting the detection accuracy, it is only necessary to rotate the rotating plate 53, and the shielding baffle 56 is driven to deflect with the slider 55 as the center through the first slide groove 54 opened on the rotating plate 53. The deflection amplitude of the six groups of shielding baffles 56 is controlled by the rotation angle of the rotating plate 53, and then the opening range of the supporting plate 58 is controlled, so that the laser will be blocked after exceeding the range and cannot be detected by the laser receiving module 37. The detection accuracy of the laser receiving module 37 is adjusted by controlling the opening size of the supporting plate 58, and then the detection guide rails 2 of different specifications are adapted. When the rotating plate 53 rotates, the rotating ring 59 fixedly connected to the rotating plate 53 rotates synchronously inside the second rotating groove 60;

[0043] The outside of the knob 30 and the rotating knob 52 are both provided with anti-slip grooves, and the front and rear sides of the inner wall of the storage cavity 25 near the bottom are fixedly connected with blocks 31. The anti-slip grooves provided on the outside of the knob 30 and the rotating knob 52 increase the friction force, making it convenient to rotate the knob 30 and the rotating knob 52.
