[0028] like Figure 1-3 As shown, this application provides a length protection detection device, comprising:
[0029] The detection component includes a base 11;
[0030] The movable components include a first slide groove 21, a slider 22, a support plate 23, a movable column 24, a first telescopic spring 25, a movable plate 26, and a rubber pad 27. The first slide groove 21 is located inside the lower end of the base 11. The slider 22 is slidably connected to the inside of the first slide groove 21. The support plate 23 is fixedly connected to the top of the slider 22. The movable column 24 is slidably connected to the center of both sides of the support plate 23. The first telescopic spring 25 is fixedly connected to both ends of the inner side of the support plate 23. The movable plate 26 is fixedly connected to the inner end of the movable column 24. The rubber pad 27 is fixedly connected to the inner side of the movable plate 26.
[0031] The first groove 21 is used to support and guide the slider 22. The slider 22 is used to support the support plate 23. The support plate 23 is used to support the computer precision rotating shaft and the movable column 24. The movable column 24 is used to support the movable plate 26. The first telescopic spring 25 is used to reset the movable plate 26. The movable plate 26 is used to support the rubber pad 27. The rubber pad 27 is used to protect the outside of the computer precision rotating shaft.
[0032] The detection assembly also includes a lead screw 12, a reciprocating motor 13, and a baffle 14. The lead screw 12 is rotatably connected to the lower end of the base 11, the reciprocating motor 13 is fixedly connected to the outer side of the base 11, and the lower end of the baffle 14 is threaded to the outer surface of the lead screw 12.
[0033] The lead screw 12 is used to drive the baffle 14 to move, the reciprocating motor 13 is used to drive the lead screw 12 to rotate, the baffle 14 is used to push the computer precision shaft, and there are scale lines on the upper side of the lower end of the base 11.
[0034] The support plate 23 has a U-shaped structure, and the other end of the first telescopic spring 25 is fixedly connected to the two outer ends of the movable plate 26.
[0035] When the movable plate 26 moves to both sides of the support plate 23, the movable plate 26 drives the first telescopic spring 25 to compress and generate elastic force.
[0036] The slider 22 is located above the lead screw 12, and the movable column 24 has a T-shaped structure.
[0037] The slider 22 moves on the upper end of the lead screw 12, and the movement of the slider 22 and the rotation of the lead screw 12 do not affect each other.
[0038] Working principle: When the precision computer spindle is manufactured and its length needs to be tested, to prevent damage during the length test, the movable column 24 is pulled outward. The movable column 24 moves outward, causing the movable plate 26 and rubber pad 27 to move outward. The movable plate 26 compresses the first telescopic spring 25, causing it to generate elastic force. The precision computer spindle is then placed inside the support plate 23. The pulling force on the movable column 24 is then stopped. Under the elastic force of the first telescopic spring 25, the movable plate 26 moves the rubber pad 27 inward to clamp and fix the precision computer spindle. At this time, when the baffle 14 pushes the precision computer spindle under the drive of the lead screw 12, the precision computer spindle drives the support plate 23 and the slider 22 to slide on the upper end of the base 11. During the sliding process, the precision computer spindle remains stationary relative to the support plate 23, thereby avoiding wear on the outer surface caused by the sliding of the precision computer spindle.
[0039] Please see Figure 4 As shown, this embodiment, based on the above embodiment, further includes:
[0040] The protective assembly includes a second slide 31, a pressure sensor 32, a second telescopic spring 33, a top plate 34, a third slide 35, a movable frame 36, and a third telescopic spring 37. The second slide 31 is respectively opened on one side of the baffle 14 and one side of the base 11. The pressure sensor 32 is fixedly connected to the inside of the second slide 31. The second telescopic spring 33 is fixedly connected to the outside of the pressure sensor 32. The top plate 34 is fixedly connected to the outside of the second telescopic spring 33. The third slide 35 is respectively opened on the top of the baffle 14 and the top of one side of the base 11. The movable frame 36 is slidably connected to the inside of the third slide 35. One end of the third telescopic spring 37 is fixedly connected to the top of the baffle 14 and the top of one side of the base 11.
[0041] The second slide 31 is used to place the pressure sensor 32 and guide the top plate 34. The pressure sensor 32 is used to measure the elastic force of the second telescopic spring 33. The second telescopic spring 33 generates elastic force under the drive of the top plate 34. The top plate 34 is used to contact both ends of the computer precision rotating shaft. The third slide 35 is used to guide the movable frame 36. The movable frame 36 is used to limit the movement distance of the top plate 34. The third telescopic spring 37 is used to reset the movable frame 36.
[0042] The pressure sensor 32 is electrically connected to the reciprocating motor 13 via a circuit, and the lower end of the third slide 35 is connected to the upper end of the second slide 31.
[0043] When the pressure sensor 32 measures that the elastic force of the second extension spring 33 is at the set value, the pressure sensor 32 controls the reciprocating motor 13 to stop starting.
[0044] The other end of the third telescopic spring 37 is fixedly connected to the bottom of the upper end of the movable frame 36, and the top plate 34 is located outside the baffle 14 and outside one side of the base 11.
[0045] The movable frame 36 can move along the third slide 35 to the inside of the second slide 31 and is located inside the top plate 34.
[0046] Working principle: The greater the pushing force applied to the computer precision spindle by the baffle 14 and the base 11, the greater the squeezing force on the computer precision spindle by the baffle 14 and the base 11, which can easily cause the computer precision spindle to bend. When the squeezing force is small, the two ends of the computer precision spindle cannot fit against the baffle 14 and the base 11, resulting in inaccurate measurement results. At this time, the movable frame 36 is moved downward to enter the second slide groove 31. When the outer side of the movable frame 36 fits against the inner side of the top plate 34, the elastic force of the second telescopic spring 33 is recorded. When the baffle 14 pushes the computer precision spindle... When the top plate 34 moves to one side of the base 11 to detect its length, it contacts both ends of the computer precision shaft. As the baffle 14 continues to push, the top plate 34 moves into the second slide groove 31 and drives the second telescopic spring 33 to compress. When the elastic force of the second telescopic spring 33 is equal to the recorded elastic force, the pressure sensor 32 controls the reciprocating motor 13 to stop starting, so that the baffle 14 does not push the computer precision shaft. This completes the fixation of both ends of the computer precision shaft without applying excessive force to both sides of the computer precision shaft, further protecting the computer precision shaft.
[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
