Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A slider precision detector includes a fixed base 1, a dial fixing frame 6 is arranged above the fixed base 1, a micrometer 7 is arranged above the dial fixing frame 6, a ruby ​​probe 8 is arranged at the bottom of the micrometer 7, a positioning component 4 is arranged on the fixed base 1, and a wedge block 3 is arranged above the positioning component 4, the wedge block 3 is located inside the fixed base 1, and wire cutting rails 2 are arranged on the left and right sides of the wedge block 3, and a slider body 5 is installed outside the wire cutting rail 2;

[0028] The positioning assembly 4 includes a rotating rod 401 that passes through the fixed base 1, the end of the rotating rod 401 is fixedly connected to a connecting worm 403, and a transmission worm wheel 402 is provided on one side of the connecting worm 403, a lifting screw 404 is fixedly installed in the middle of the top of the transmission worm wheel 402, and a lifting sleeve 405 is installed on the outside of the lifting screw 404 through a screw nut, and the lifting sleeve 405 is installed at the bottom of the wedge block 3.

[0029] By adopting the above technical solution, the slider body 5 is installed on the wire cutting rail 2 and moves in the direction close to the ruby ​​probe 8 until the slider body 5 and the positioning rod on the table fixing frame 6 abut against each other. At this time, the ruby ​​probe 8 points to the wedge block 3, and the rotary rod 401 is rotated. The rotary rod 401 drives the connecting worm 403 to rotate, thereby driving the transmission worm wheel 402 to rotate through the connecting worm 403. At this time, the lifting sleeve 405 on the transmission worm wheel 402 drives the wedge block 3 to move upward under the action of the screw nut. At this time, the wedge block 3 pushes the wire cutting rail 2 to move to both sides until the wire cutting rail 2 and the groove of the slider body 5 abut against each other, and then the micrometer 7 measures the distance between it and the wedge block 3.

[0030] Specifically, Figure 3 As shown, the side of the wire cutting rail 2 close to the wedge block 3 is tightly attached to the wedge block 3, and the slope of the wedge block 3 is 5°, a guide groove 11 is provided at the connection between the wedge block 3 and the fixed base 1, and the wedge block 3 is lifted and lowered in the fixed base 1 through the guide groove 11, the wire cutting rail 2 is evenly distributed about the vertical center line of the wedge block 3, and the upper width of the wedge block 3 is smaller than the lower width of the wedge block 3, a mounting hole 9 is provided at the connection between the meter fixing frame 6 and the micrometer 7, and a fixing screw 10 is penetrated inside the meter fixing frame 6, and the fixing screw 10 is threadedly connected to the fixed base 1, a guide rod 12 is provided on the side of the wire cutting rail 2 away from the wedge block 3, and the guide rod 12 runs through the inside of the fixed base 1, and the slider body 5 is slidably connected to the wire cutting rail 2.

[0031] By adopting the above technical solution, when the wedge block 3 moves upward, it can slide in the guide groove 11, and at the same time, the wire cutting rail 2 slides laterally inside the fixed base 1 through the guide rod 12. Since the angle between the notch of the wire cutting rail 2 and the wedge block 3 is 5°, cot5°=B / C is approximately equal to 11.4, B is the moving distance of the wedge block 3 moving upward, and C is the lateral moving distance of the wire cutting rail 2, so that the lateral moving distance of the wire cutting rail 2 can be calculated, thereby obtaining the groove span of the slider body 5. Here, the slope ratio is used, and the micrometer 7 is used to measure the span data, and the detection accuracy can be about 0.0002mm. Similarly, the slope ratio can also reduce the error of the detection itself by about 11 times. Conversely, the span display is about 11 times larger than the original, further improving the span measurement accuracy.

[0032] Working principle: The slider body 5 is installed on the wire cutting rail 2 and moves toward the direction close to the ruby ​​probe 8 until the slider body 5 and the positioning rod on the table fixing frame 6 abut against each other. At this time, the ruby ​​probe 8 points to the wedge block 3, and the rotary rod 401 is rotated. The rotary rod 401 drives the connecting worm 403 to rotate, thereby driving the transmission worm wheel 402 to rotate through the connecting worm 403. At this time, the lifting sleeve 405 on the transmission worm wheel 402 drives the wedge block 3 to move upward in the guide groove 11 under the action of the screw nut. At this time, the wedge block 3 pushes the wire cutting rail 2 to move to both sides through the guide rod 12 until the wire cutting rail 2 and the groove of the slider body 5 abut against each other, and the upward movement distance of the wedge block 3 is measured to obtain the lateral movement distance of the wire cutting rail 2, thereby calculating the span of the slider body 5.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
