[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0021] When the existing device performs jump detection, since the fixing frame of the micrometer is fixed to the supporting frame of the lead screw by tightening the bolts, when detecting different points, the bolts need to be tightened and loosened repeatedly, resulting in low detection efficiency.

[0022] Embodiment 1: A rapid detection device for assembling an optical image measuring instrument frame, such as Figure 1-Figure 3As shown, it includes a T-shaped first mounting frame 1, a T-shaped second mounting frame 2 is slidably connected to the right side of the first mounting frame 1, a tension spring is arranged between the second mounting frame 2 and the first mounting frame 1, and the tension spring is used to make the second mounting frame 2 move toward the first mounting frame 1, and the first mounting frame 1 and the second mounting frame 2 are both slidably connected with a T-shaped third mounting frame 3 and a first sliding rod 4, the third mounting frame 3 slides vertically, and the first sliding rod 4 slides horizontally, the third mounting frame 3 on the first mounting frame 1 and the third mounting frame 3 on the second mounting frame 2 are symmetrically distributed, and springs are arranged between the two third mounting frames 3 and the first mounting frame 1 and the second mounting frame 2, respectively, and the springs are used to reset the adjacent third mounting frames 3, and the first sliding rod 4 on the first mounting frame 1 and the first sliding rod 4 on the second mounting frame 2 The sliding rods 4 are symmetrically distributed, and springs are respectively arranged between the two first sliding rods 4 and the first mounting frame 1 and the second mounting frame 2, and the springs are used to reset the adjacent first sliding rods 4. The back sides of the two first sliding rods 4 are fixedly connected to the limit frame 5, and the limit frame 5 is composed of three rods perpendicular to each other. The upper side of the vertical rod of the limit frame 5 is fixedly connected to the fourth mounting frame 6, and the first mounting frame 1, the second mounting frame 2, the third mounting frame 3 and the fourth mounting frame 6 are all rotatably connected to symmetrically distributed rollers, which are used to facilitate the movement of the device along the support frame. A fixed seat 7 is fixedly provided on the left side of the left third mounting frame 3, and the upper side of the fixed seat 7 is rotatably connected to the first rotating rod 8, and the upper side of the first rotating rod 8 is rotatably connected to the second rotating rod 9, and a micrometer 10 is arranged on the right side of the second rotating rod 9.

[0023] like Figure 3 and Figure 4 As shown, a limiting block 11 is slidably connected inside the first mounting frame 1, and the second mounting frame 2 is provided with evenly distributed limiting grooves. The limiting block 11 is limitedly matched with the adjacent limiting grooves on the second mounting frame 2. When the limiting block 11 is inserted into the adjacent limiting groove on the second mounting frame 2, the second mounting frame 2 cannot move to the left. A spring is provided between the limiting block 11 and the first mounting frame 1, and the spring is used to move the limiting block 11 upward. The limiting block 11 is fixedly connected to a second sliding rod 12, and the second sliding rod 12 penetrates the first mounting frame 1.

[0024] like Figure 4 As shown, a first limiting column 13 is slidably connected inside the first mounting frame 1, and a spring is arranged between the first limiting column 13 and the first mounting frame 1. The spring is initially in a compressed state, and is used to enable the first limiting column 13 to limit the limiting block 11. The limiting block 11 is provided with a groove that cooperates with the first limiting column 13. When the first limiting column 13 is inserted into the groove of the limiting block 11, the limiting block 11 cannot move upward under the action of the adjacent spring.

[0025] like Figure 5As shown, the third mounting frame 3 is provided with evenly distributed limit grooves, and two limit frames 5 are slidably connected to the first mounting frame 1 and the second mounting frame 2 respectively. The limit frames 5 are limitedly matched with adjacent limit grooves on the adjacent third mounting frame 3. When the limit frames 5 are inserted into the adjacent limit grooves on the third mounting frame 3, the third mounting frame 3 cannot move downward.

[0026] like Figure 5 As shown, the upper side of the third mounting frame 3 is slidably connected with an inverted "mountain" shaped sliding frame 14, a spring is arranged between the sliding frame 14 and the adjacent third mounting frame 3, the spring is used to reset the sliding frame 14, the third mounting frame 3 is slidably connected with two first brake blocks 15 symmetrically distributed front and back, the two first brake blocks 15 are each provided with a spring and a thin rope between the adjacent sliding frames 14, the spring is initially in a compressed state, used to make the first brake blocks 15 apply pressure to the adjacent rollers, the thin rope is initially in a taut state, used to separate the adjacent first brake blocks 15 from the adjacent rollers, the rollers are composed of a cylinder and a round rod, the round rod serves as a rotating shaft, the first brake block 15 is frictionally matched with the round rod portion of the adjacent roller, when the first brake block 15 contacts the adjacent roller, the first brake block 15 relies on the friction between it and the adjacent roller to prevent the roller from rotating.

[0027] like Figure 3 and Figure 5 As shown, the back sides of the two third mounting frames 3 are slidably connected with limit rods 16, and a tension spring is arranged between the limit rods 16 and the adjacent third mounting frames 3, and the tension spring is used to reset the adjacent limit rods 16, and the sliding frame 14 is provided with evenly distributed limit grooves, and the limit rods 16 are limitedly matched with the adjacent limit grooves on the adjacent sliding frames 14. When the limit rods 16 are inserted into the adjacent limit grooves on the adjacent sliding frames 14, the sliding frame 14 cannot move upward.

[0028] When the device is used to detect the lead screw of the optical image measuring instrument to be assembled, the two third mounting frames 3 are first moved upward, the third mounting frames 3 move upward and compress the adjacent springs, and at the same time, the two third mounting frames 3 squeeze the adjacent limit frames 5 respectively, so that the two limit frames 5 move back to back, and the limit frames 5 drive the adjacent first sliding rods 4 to move, and the first sliding rods 4 compress the adjacent springs. When the distance between the rollers on the two third mounting frames 3 and the corresponding rollers on the first mounting frame 1 and the second mounting frame 2 is greater than the thickness of the support frame for installing the lead screw, the third mounting frames 3 are stopped from moving. At this time, the two first sliding rods 4 are respectively on the adjacent springs. Under the action of , the adjacent limiting frames 5 are driven to move toward each other, and the limiting frames 5 are inserted into the adjacent limiting grooves on the adjacent third mounting frames 3, thereby jamming the third mounting frame 3 and preventing the third mounting frame 3 from moving downward. Then, the second mounting frame 2 is pulled to the right, and the second mounting frame 2 stretches the adjacent tension spring. When the second mounting frame 2 moves, the second mounting frame 2 squeezes the limiting block 11, causing the limiting block 11 to move downward and compress the adjacent spring. When the distance between the two third mounting frames 3 is greater than the width of the support frame, the second mounting frame 2 is stopped from moving. At this time, the limiting block 11 moves upward under the action of the adjacent spring and is inserted into the adjacent limiting grooves on the second mounting frame 2.

[0029] The limiting block 11 moves upward and is inserted into the adjacent limiting groove on the second mounting frame 2, and then the device is moved so that the device moves upward from the lower side of the support frame to frame the support frame. When the upper side of each roller on the first mounting frame 1 and the second mounting frame 2 is aligned with the lower side of the support frame, the device stops moving and moves to the right so that the roller on the first mounting frame 1 contacts the lower side of the support frame. When the first mounting frame 1 moves, the first mounting frame 1 drives the adjacent first sliding rod 4 under the action of the spring adjacent to the first sliding rod 4 and drives the adjacent limiting frame 5 to move, and the limiting frame 5 drives the adjacent fourth mounting frame 6 to move. When the roller on the fourth mounting frame 6 contacts the left side of the support frame, the fourth mounting frame 6 drives the adjacent first sliding rod 4 and the adjacent limiting frame 5 to stop moving. At this time, the first mounting frame 1 continues to move. At this time, the first mounting frame 1 compresses the spring between the adjacent first sliding rod 4. At the same time, the first mounting frame 1 drives the adjacent third mounting frame 3 to gradually separate from the adjacent limiting frame 5. When the limiting frame 5 is separated from the limiting groove on the adjacent third mounting frame 3, the third mounting frame 3 on the left moves downward under the action of the adjacent spring until the lower side of the two rollers on the third mounting frame 3 contacts the upper side of the support frame.

[0030] After the lower sides of the two rollers on the left third mounting bracket 3 contact the upper side of the supporting bracket, the second sliding rod 12 is pulled downward, and the second sliding rod 12 drives the limit block 11 to move downward and compress the adjacent spring. During the downward movement of the limit block 11, after it contacts the first limit column 13, the limit block 11 squeezes the first limit column 13 to make it move rightward and compress the adjacent spring. When the limit block 11 moves until the groove on it is aligned with the first limit column 13, the second sliding rod 12 is stopped. At this time, the first limit column 13 is inserted into the groove of the limit block 11 under the action of the adjacent spring, thereby fixing the limit block 11. When the limit block 11 is separated from the adjacent grooves on the second mounting bracket 2 When the second mounting frame 2 is separated, the second mounting frame 2 moves to the left under the action of the adjacent tension spring, and the second mounting frame 2 drives the adjacent fourth mounting frame 6 to move to the left through the adjacent first sliding rod 4 and the adjacent limiting frame 5. When the left side of the roller on the fourth mounting frame 6 on the right side contacts the right side of the support frame, the fourth mounting frame 6 stops moving. At this time, the second mounting frame 2 drives the adjacent third mounting frame 3 to continue to move, so that the limiting groove on the third mounting frame 3 on the right side is separated from the adjacent limiting frame 5, so that the third mounting frame 3 on the right side moves downward under the action of the adjacent spring, so that the lower sides of the two rollers on the third mounting frame 3 on the right side contact the upper side of the support frame, and the installation of the device on the support frame is completed.

[0031] After the device is installed on the support frame, the device is moved forward and backward to the position for detecting the lead screw, and then the two sliding frames 14 are moved downward. The sliding frames 14 move downward and compress the adjacent springs. At the same time, the sliding frames 14 squeeze the adjacent limit rods 16. The two limit rods 16 move back to back and stretch the adjacent tension springs. When the sliding frame 14 moves downward, the two adjacent first brake blocks 15 are pushed downward by the front and rear adjacent springs respectively. When the first brake block 15 moves to contact the round rod part of the adjacent roller, it stops moving. At this time, the sliding frame 14 continues to move downward and will contact the first brake block 15 with the first brake block 15. The spring adjacent to the first brake block 15 is further compressed, and the adjacent thin rope is relaxed, thereby increasing the pressure of the first brake block 15 on the adjacent roller rod part, so that the first brake block 15 can brake the adjacent roller to avoid the movement of the device during detection. When the sliding frame 14 stops moving, the limit rod 16 is inserted into the adjacent limit groove on the sliding frame 14 under the action of the adjacent tension spring, thereby fixing the sliding frame 14, and then the first rotating rod 8 and the second rotating rod 9 are rotated to adjust the position of the micrometer 10 so that the probe of the micrometer 10 contacts the screw, thereby performing a jump detection on the screw.

[0032] After completing the detection of a point, rotate the first rotating rod 8 and the second rotating rod 9 to separate the probe of the micrometer 10 from the lead screw, then pull the two limit rods 16 in opposite directions, and stretch the adjacent tension springs when the limit rods 16 move. After the sliding frame 14 loses the limit of the adjacent limit rods 16, it moves upward under the action of the adjacent springs, and pulls the adjacent two first brake blocks 15 from the adjacent two rollers through the two adjacent thin ropes. Then, move the device forward and backward to the next detection point, and then move the sliding frame 14 downward to lock the rollers, and adjust the first rotating rod 8 and the second rotating rod 9 to make the probe of the micrometer 10 contact with the lead screw again. After all points are detected, push the second sliding rod 12 upwards, the second sliding rod 12 drives the limit block 11 to move, and the limit block 11 squeezes the first limit column 13. After the limit block 11 loses the limit of the first limit column 13, it is reinserted into the adjacent limit groove on the second mounting frame 2 under the action of the adjacent spring, and then the second mounting frame 2 is pulled to the right to separate the six rollers on the right side of the second mounting frame 2 from the support frame. When the distance between the two third mounting frames 3 is greater than the width of the support frame, move the device to the left to separate the six rollers on the left side from the support frame, and then move the device downward to remove the device from the support frame.

[0033] During testing, the multi-stage adjustment rod for fixing the micrometer is also fixed by tightening bolts, which results in low testing efficiency when the position of the micrometer needs to be adjusted frequently.

[0034] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 7 As shown, it also includes a second brake block 17, which is slidably connected to the first rotating rod 8, and a first sliding plate 18 is slidably connected to the first rotating rod 8. The first sliding plate 18 is located above the second brake block 17, and a spring is arranged between the first sliding plate 18 and the second brake block 17. The spring is used to make the second brake block 17 apply pressure to the fixed seat 7, and the second brake block 17 is frictionally matched with the fixed seat 7. When the second brake block 17 is tightly attached to the fixed seat 7, the friction force between the two is used to fix the fixed seat 7 and the first rotating rod 8.

[0035] like Figure 6 and Figure 7As shown, a second sliding plate 19 is slidably connected inside the first rotating rod 8, and the second sliding plate 19 is located above the first sliding plate 18. The second sliding plate 19 is threadedly connected to a first threaded rod 20 rotatably connected to the first sliding plate 18. A second limiting column 21 is slidably connected inside the first rotating rod 8, and a spring is arranged between the second limiting column 21 and the first rotating rod 8. The spring is initially in a compressed state, and is used to limit the second sliding plate 19 by the second limiting column 21. The second sliding plate 19 is provided with a groove that cooperates with the second limiting column 21 for limiting. When the second limiting column 21 is inserted into the groove of the second sliding plate 19, the second sliding plate 19 cannot move upward under the action of the spring adjacent to the first sliding plate 18.

[0036] like Figure 6 and Figure 8 As shown, a third brake block 22 is slidably connected to the rear side of the first rotating rod 8, and a third sliding plate 23 is slidably connected to the first rotating rod 8. The third sliding plate 23 is located in front of the third brake block 22. A spring is arranged between the third sliding plate 23 and the third brake block 22, and the spring is used to make the third brake block 22 apply pressure to the second rotating rod 9. The third brake block 22 and the second rotating rod 9 are frictionally matched. When the third brake block 22 and the second rotating rod 9 are in close contact, the friction force between the two enables the second rotating rod 9 and the first rotating rod 8 to be fixed.

[0037] like Figure 6 and Figure 8 As shown, a fourth sliding plate 24 is slidably connected in the first rotating rod 8, and the fourth sliding plate 24 is located in front of the third sliding plate 23. The fourth sliding plate 24 is threadedly connected to a second threaded rod 25 rotatably connected to the third sliding plate 23. A third limiting column 26 is slidably connected in the first rotating rod 8. A spring is arranged between the third limiting column 26 and the first rotating rod 8. The spring is initially in a compressed state, and is used to limit the fourth sliding plate 24 by the third limiting column 26. The fourth sliding plate 24 is provided with a groove that cooperates with the third limiting column 26 to limit the fourth sliding plate 24. When the third limiting column 26 is inserted into the groove of the fourth sliding plate 24, the fourth sliding plate 24 cannot move forward under the action of the spring adjacent to the third sliding plate 23.

[0038] The mechanism composed of the second brake block 17, the first sliding plate 18, the second sliding plate 19, the first threaded rod 20 and the second limiting column 21 has the same principle as the mechanism composed of the third brake block 22, the third sliding plate 23, the fourth sliding plate 24, the second threaded rod 25 and the third limiting column 26. Here, the mechanism composed of the second brake block 17, the first sliding plate 18, the second sliding plate 19, the first threaded rod 20 and the second limiting column 21 is explained. Before rotating the first rotating rod 8 and the second rotating rod 9, the first threaded rod 20 is rotated first, and the first threaded rod 20 drives the second sliding plate 19 to move to adjust the distance between the first sliding plate 18 and the second sliding plate 19. After the adjustment is completed, the first threaded rod 20 is pressed downward, and the first threaded rod 20 drives the first sliding plate 18 and the second sliding plate 19 to move downward. When the first sliding plate 18 moves downward, it gradually compresses the adjacent The spring causes the pressure of the second brake block 17 on the fixed seat 7 to gradually increase. When the second sliding plate 19 moves to contact the second limiting column 21, the second sliding plate 19 squeezes the second limiting column 21, and the second limiting column 21 moves to the left and compresses the adjacent spring. When the groove on the second sliding plate 19 is aligned with the second limiting column 21, the second limiting column 21 is inserted into the groove on the second sliding plate 19 under the action of the adjacent spring, thereby fixing the second sliding plate 19, thereby making it impossible for the fixed seat 7 and the first rotating rod 8 to rotate. When the second sliding plate 19 moves to align with the second limiting column 21, the compression amount of the spring between the first sliding plate 18 and the second brake block 17 is changed through the above-mentioned process of rotating the first threaded rod 20, thereby changing the pressure of the second brake block 17 on the fixed seat 7, thereby adjusting the fixing force between the fixed seat 7 and the first rotating rod 8.

[0039] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
