Description

Technical Field

[0001] This utility model relates to the field of stress testing, specifically a stress meter device that can electrically and horizontally adjust the rotation direction of the stress meter. Background Technology

[0002] The principle of stress detection technology relies on X-rays emitted from an X-ray tube, which irradiate the sample and are reflected to a detector. The detector receives the signal and calculates the stress value at that point in the sample. Sometimes, when measuring the stress value at a specific point, it is necessary to rotate the stress meter horizontally by an angle (φ) before taking the measurement to accurately determine the stress state at that point. Currently, some existing stress meters lack the function of horizontally adjusting the rotation direction (φ), or while they have this function, it requires manual rotation. This is insufficient in terms of efficiency, accuracy, and automation to meet current stress testing requirements. Therefore, there is an urgent need for a stress meter device that can electrically adjust the horizontal rotation direction (φ). Utility Model Content

[0003] To solve the above problems, this utility model discloses a stress meter φ angle rotation device.

[0004] The specific technical solution is as follows:

[0005] A stress meter φ angle rotation device includes a support arm, a drive mechanism, a rotation mechanism, a transition plate, and left and right adjustment plates. The support arm is installed at the front end of a bracket, and the drive mechanism and the rotation mechanism are installed inside the support arm. The bottom of the rotation mechanism is connected to the transition plate, and the transition plate is connected to the left and right adjustment plates through a sliding structure. The left and right adjustment plates are connected to the stress meter assembly.

[0006] The drive mechanism includes a motor, a motor mounting base, a synchronous pulley A, a synchronous pulley B, a synchronous belt, a worm gear, a bearing A, and a bearing housing. The motor is fixed to the motor mounting base, which is installed inside the support arm. The output shaft of the motor is connected to the synchronous pulley A, which is connected to the synchronous pulley B via a synchronous belt. The worm gear is fixedly connected to the inner hole of the synchronous pulley B, and both ends of the worm gear are supported in the bearing housing by bearing A.

[0007] The rotating mechanism includes a rotating shaft, a worm gear, bearing B, a bearing cover, a locking nut, front and rear adjusting plates, and a lifting ring. The worm gear is fixedly installed on the outer side of the rotating shaft, and the worm gear meshes with the worm. The bottom of the rotating shaft is supported by a pair of bearings B, and the bearings B are positioned above each other by a bearing cover. The tightness of the bearings B is adjusted by the locking nut. The bottom end of the rotating shaft is connected to the front and rear adjusting plates, and the top end of the rotating shaft is provided with a lifting ring.

[0008] The front and rear adjustment plates are slidably connected to the upper end of the adapter plate via dovetail grooves. The middle part of the adapter plate is also provided with a dovetail groove structure and is slidably connected to the dovetail grooves of the left and right adjustment plates.

[0009] The cable is fixed to the lifting ring, and the rotation of the shaft drives the lifting ring, the adapter plate, the left and right adjustment plates, the stress meter assembly, and the cable to rotate synchronously.

[0010] The support arm has a stepped groove inside. After the bearings B are sleeved on the rotating shaft in pairs, the bottom end of the bearing abuts against the shoulder of the stepped groove. The top end of the bearing B protrudes at the top end of the stepped groove. The bearing cap is set in the shape of the bearing B at the top end of the stepped groove, and the bearing cap is fixedly connected to the support arm.

[0011] The rotating shaft is stepped and has a retaining ring in the middle.

[0012] The relative position of the vertex of the stress meter assembly to the center line of the rotating shaft is adjusted by the dovetail groove structure between the front and rear adjustment plates and the adapter plate, as well as between the adapter plate and the left and right adjustment plates.

[0013] The advantages of this utility model are: it has the ability to electrically adjust the angle. This device can rotate the stress meter assembly by ±90 degrees through the motor to meet the stress test at various angles. The lifting ring and the cable rotate synchronously with the stress meter assembly to ensure the stability and reliability of the cable and avoid the cable from being bent or loose, which would affect its use. Combined with the adjustment mechanism, the sliding of the front and rear adjustment plates and the left and right adjustment plates makes the vertex M in the stress meter assembly coincide with the center line of the rotating shaft in the rotation mechanism, ensuring the accuracy of the test.

The two ends of the worm gear 306 are supported in the bearing seat 308 by the bearing A307.

[0023] The rotating mechanism 4 includes a rotating shaft 401, a worm gear 402, a bearing B403, a bearing cover 404, a locking nut 405, a front and rear adjusting plate 406, and a lifting ring 407. The worm gear 402 is fixedly installed on the outer side of the rotating shaft 401, and the worm gear 402 meshes with the worm 306. The bottom of the rotating shaft 401 is supported by a pair of bearings B403, and the bearings B403 are positioned above the bearing cover 404. The tightness of the bearings B403 is adjusted by the locking nut 405. The bottom end of the rotating shaft 401 is connected to the front and rear adjusting plate 406, and the top end of the rotating shaft 401 is provided with a lifting ring 407.

[0024] The front and rear adjustment plates 406 are slidably connected to the upper end of the adapter plate 5 via dovetail grooves. The middle part of the adapter plate 5 is also provided with a dovetail groove structure and is slidably connected to the left and right adjustment plates 6 via dovetail grooves.

[0025] The cable 8 is fixed to the lifting ring 407. The rotation of the rotating shaft 401 drives the lifting ring 407, the adapter plate 5, the left and right adjustment plates 6, the stress meter assembly 7 and the cable 8 to rotate synchronously.

[0026] The support arm 1 has a stepped groove inside. After the bearings B403 are sleeved on the rotating shaft 401 in pairs, the bottom end of the bearings B403 abuts against the shoulder of the stepped groove.

The worm gear 306 meshes with the worm wheel 402 of the rotating mechanism 4 to drive the rotating shaft 401 to rotate, which in turn drives the adapter plate 5, the left and right adjustment plate 6 and the stress meter assembly 7 to rotate ±90 degrees. At the same time, the lifting ring 407 of the cable 8 fixed to the top of the rotating shaft 401 rotates accordingly to avoid twisting or loosening. Combined with the high transmission ratio of the worm gear and the closed-loop feedback of the servo motor, the angle is digitally controlled precisely.
