Description

[0002] In the fields of machining and measurement, calipers are a commonly used precision measuring tool, widely applied to the dimensional measurement of various parts. However, during the manufacturing process of calipers, factors such as processing techniques, material properties, or accidental collisions during transportation can cause calipers to twist and deform. This twisting and deformation directly affects the measuring accuracy of the calipers, thereby impacting product quality and production efficiency.

Furthermore, traditional correction methods usually require multiple measurements and repeated adjustments, which are not only time-consuming and labor-intensive but also difficult to achieve high-precision correction results.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0030] Reference Figure 1 and 2 As shown, the caliper torsion calibration machine of this utility model includes:

[0031] Rack 1;

[0032] The caliper positioning mechanism 2 is used to clamp and position the caliper; the caliper positioning mechanism 2 includes a first clamping device 21 and a second clamping device 22 arranged opposite to each other;

[0033] A measuring mechanism 3 is disposed between the first clamping device 21 and the second clamping device 22 for measuring the torsion angle of the caliper. The measuring mechanism 3 includes a measuring arm 31, a positioning ring 32, a measuring base plate 33, a measuring frame 34, a lifting mechanism 35, and a laser rangefinder 36. The measuring arm 31 is mounted on the measuring base plate 33 through the positioning ring 32, so that the measuring arm 31 can rotate around the measuring base plate 33. The measuring base plate 33 is connected to the lifting mechanism 35 through the measuring frame 34. The laser rangefinder 36 is disposed on the measuring base plate 33.

[0034] The torsion correction mechanism 4 is connected to the first clamping device 21 and is used to rotate the caliper to achieve correction. The torsion correction mechanism 4 includes a rotating mechanism 41, a rotating clamp shaft 42 and a rotating clamp support 43. The rotating clamp shaft 42 is mounted on the frame 1 through the rotating clamp support 43. The output end of the rotating mechanism 41 is connected to the first clamping device 21 through the rotating clamp shaft 42.

[0035] Furthermore, the bottom of the second clamping device 22 is provided with a displacement adjustment mechanism 23. The second clamping device 22 is controlled to move through the displacement adjustment mechanism 23 to adjust the distance between it and the first clamping device 21. The displacement adjustment mechanism 23 allows the second clamping device 22 to flexibly adjust its position according to the size and shape of the caliper, thereby adjusting the distance between it and the first clamping device 21. This greatly improves the applicability of the caliper torsion caliper, enabling it to adapt to calipers of different specifications and sizes, enhancing the versatility and flexibility of the equipment, and reducing the equipment costs for enterprises.

[0036] like Figure 5 As shown, the displacement adjustment mechanism 23 includes a set of guide rails 231, a first servo motor 232, a lead screw 233, and a sliding seat 234. The lead screw 233 is positioned in the middle of the set of guide rails 231. One end of the lead screw 233 is connected to the output shaft of the first servo motor 232, and the other end is connected to the sliding seat 234 via a lead screw nut. The second clamping device 22 is mounted on the sliding seat 234 and slidably connected to the guide rails 231. The precise driving performance of the first servo motor 232 and the stable transmission of the lead screw 233 ensure the smooth movement of the second clamping device 22, improving the accuracy and reliability of caliper positioning. Furthermore, this displacement adjustment mechanism 23 has a high degree of automation, which can improve production efficiency, reduce manual intervention, and lower labor intensity.

[0037] like Figure 4 As shown, both the first clamping device 21 and the second clamping device 22 include a fixed frame 211, a caliper 212, and a connecting rod self-locking structure. The caliper 212 and the connecting rod self-locking structure are both mounted on the fixed frame 211. The caliper 212 is controlled by the connecting rod self-locking mechanism to achieve its opening and closing action. The fixed frame 211 provides stable support for the caliper 212, ensuring its stability during operation. Under the control of the connecting rod self-locking mechanism, the caliper 212 can firmly clamp the caliper, preventing it from loosening or shifting during measurement and calibration, thereby ensuring the measurement and calibration accuracy of the torsion caliper.

[0038] Preferably, the caliper 212 includes a lower jaw 213 and an upper jaw 214. The linkage self-locking structure includes a linkage assembly 215 and a cylinder 216. The lower jaw 213 is disposed at the bottom of the fixed frame 211, and the cylinder 216 is disposed at the top of the fixed frame 211 via a fixed seat. The upper jaw 214 is provided with a clamping switching rod 217, which is connected to the telescopic end of the cylinder 216 via the linkage assembly 215. The cylinder 216 drives the linkage assembly 215 to realize the clamping and releasing actions of the upper jaw 214, making the clamping process more automated and labor-saving. The clamping switching rod 217 can easily realize the switching of the clamping state, improve the operation convenience of the caliper 212, provide stable clamping force, and ensure the stability and reliability of the caliper during measurement and calibration.

[0039] Furthermore, the upper jaw 214 is surrounded by a bushing seat 218 on the outside of the clamping switching rod 217, and a guide post 219 is provided between the bushing seat 218 and the upper jaw 214. The bushing seat 218 provides stable support for the upper jaw 214, preventing it from shifting or shaking during movement; the guide post 219 ensures that the upper jaw 214 moves in the correct direction, improving the movement accuracy and reliability of the caliper 212. This structural design helps to further improve the clamping accuracy and stability of the caliper torsion setter.

[0040] Preferably, the linkage assembly 215 includes a two-hole clamping device plate 2151 and a three-hole clamping device plate 2152. One end of the three-hole clamping device plate 2152 is connected to the telescopic end of the cylinder 216, and the other end of the three-hole clamping device plate 2152 is connected to one end of the two-hole clamping device plate 2151. The middle positions of the two-hole clamping device plate 2151 are connected to the fixed frame 211 via hinge bases. The other end of the two-hole clamping device plate 2151 is connected to the clamping switching rod 217. The design of the linkage assembly 215 enables effective connection and force transmission between the cylinder 216 and the clamping switching rod 217. This structural design makes the movement of the caliper 212 more flexible and stable, ensuring a uniform distribution of clamping force and improving the clamping effect of the clamping device. Simultaneously, the connection between the hinge base and the fixed frame 211 ensures the motion accuracy and reliability of the linkage assembly 215, further improving the performance of the caliper torsion caliper.

[0041] Furthermore, the rotating shaft 42 of the caliper is provided with an angle scale 44. The angle scale 44 on the rotating shaft 42 of the caliper can intuitively display the real-time rotation position of the caliper 212, providing the operator with an accurate reference and further improving the accuracy and reliability of the calibration.

[0042] Furthermore, a protective cover 11 is provided on the frame 1 outside the first clamping device 21 and the second clamping device 22.

[0043] Preferably, the rotating mechanism 41 includes a second servo motor and a reducer, with the second servo motor and the reducer connected via a flange. The second servo motor features high precision and high response speed, ensuring the accuracy and stability of the rotation process; the reducer reduces the rotational speed and increases the torque, ensuring that the rotating shaft 42 of the caliper can rotate smoothly and powerfully. This rotating mechanism 41 improves the calibration accuracy and reliability of the caliper torsion checker, further enhancing the performance and quality of the equipment.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
