Description

Technical Field

[0001] This utility model belongs to the field of fatigue testing technology for special equipment, and in particular relates to a residual stress detection fixture for fatigue testing of special equipment. Background Technology

[0002] Special equipment refers to boilers, pressure vessels (including gas cylinders), pressure pipelines, elevators, lifting machinery, passenger ropeways, large amusement facilities, and special motor vehicles used in factories or plants that pose significant risks to personal and property safety. Some of these special equipment are equipped with special tempered glass due to their usage scenarios. During a period of use, the special tempered glass needs to undergo residual stress testing to test its fatigue level and determine its fatigue degree.

[0003] When using a residual stress tester to test special glass, the glass needs to be placed still, and in some cases, it is limited by tightening bolts. This means that the bolts need to be turned before and after the test, which is somewhat inconvenient. Therefore, a residual stress testing fixture for fatigue testing of special equipment is needed, which can quickly clamp and position the glass to be tested, so that the special glass can be easily disassembled and assembled, thereby improving the positioning efficiency during the testing of special glass. Summary of the Invention

[0004] The purpose of this invention is to provide a residual stress testing fixture for fatigue testing of special equipment, which can quickly clamp and position the glass to be tested, so as to facilitate the easy assembly and disassembly of the special glass, thereby improving the positioning efficiency during the testing of special glass and solving the technical problems mentioned in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A residual stress detection fixture for fatigue testing of special equipment includes a carrier plate; a detection platform is fixedly connected to the bottom of the carrier plate; a motor is fixedly installed on the top of the detection platform by bolts; a slide rod is slidably connected to the inner wall of the carrier plate; a crossbar is fixedly connected to the bottom end of the slide rod; a fixing block is welded to the surface of the crossbar; a rotating plate is fixedly connected to the output shaft of the motor by a flange; a connecting rod is rotatably connected between the rotating plate and the fixing block; a support base is welded to the top of the carrier plate; a T-shaped block is rotatably connected to the inner wall of the support base; a clamping block is provided on the surface of the T-shaped block; a positioning block is welded to the top of the carrier plate; a control box is fixedly installed on the top of the detection platform by bolts; a U-shaped block is welded to the top of the slide rod; a dial is integrally formed on the surface of the T-shaped block; and a residual stress detector is installed on the surface of the carrier plate.

[0006] Preferably, a pad strip is adhered to the inner wall of the positioning block.

[0007] Preferably, a bolt is installed between the T-block and the clamping block.

[0008] Preferably, the surface of the U-shaped block is provided with a groove that matches the dial shaft, and the end of the dial shaft extends into the inner cavity of the U-shaped block.

[0009] Preferably, the residual stress detector and the motor are both electrically connected to the control box via wires.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model places the glass on top of the carrier plate, and then drives the rotating plate to rotate through the motor. The rotating plate moves the fixed block and the crossbar through the connecting rod. Then the crossbar drives the U-shaped block to move the pivot shaft through the slide rod. The pivot shaft drives the clamping block to rotate through the T-shaped block and squeezes the glass to fit and position it against the positioning block. This can achieve the purpose of quickly clamping and positioning the glass to be tested, so as to facilitate the easy assembly and disassembly of special glass, thereby making the positioning efficiency better when testing special glass.

[0012] 2. This utility model uses a padding strip to protect the special glass from the positioning block, thus preventing crushing damage when the two are in direct contact.

[0013] 3. The bolts in this invention facilitate the assembly and disassembly of the T-block and the clamping block, making it easy to replace the clamping block when it is damaged, thereby improving the convenience of subsequent maintenance. Attached Figure Description

[0023] Figure 1-4This invention illustrates a residual stress testing fixture for fatigue testing of special equipment according to an embodiment of the present invention. It includes a carrier plate 1; a testing platform 2 is fixedly connected to the bottom of the carrier plate 1; a motor 3 is bolted to the top of the testing platform 2; a sliding rod 4 is slidably connected to the inner wall of the carrier plate 1; a crossbar 5 is fixedly connected to the bottom end of the sliding rod 4; a fixing block 6 is welded to the surface of the crossbar 5; a rotating plate 7 is fixedly connected to the output shaft of the motor 3 via a flange; a connecting rod 8 is rotatably connected between the rotating plate 7 and the fixing block 6; a support base 9 is welded to the top of the carrier plate 1; and the inner wall of the support base 9 can rotate. A T-shaped block 10 is connected, and a clamping block 11 is provided on the surface of the T-shaped block 10. A positioning block 12 is welded to the top of the carrier plate 1. A control box 14 is fixedly installed on the top of the detection platform 2 by bolts. A U-shaped block 16 is welded to the top of the slide rod 4. A dial shaft 17 is integrally formed on the surface of the T-shaped block 10. A dial groove adapted to the dial shaft 17 is opened on the surface of the U-shaped block 16. The end of the dial shaft 17 extends into the inner cavity of the U-shaped block 16. A residual stress detector 18 is installed on the surface of the carrier plate 1. The residual stress detector 18 and the motor 3 are electrically connected to the control box 14 by wires.

[0024] Working principle: When using this utility model, the user places the glass on the top of the carrier plate 1, and then the motor 3 drives the rotating plate 7 to rotate. The rotating plate 7 moves the fixed block 6 and the crossbar 5 through the connecting rod 8. Then, the crossbar 5 slides in the inner wall of the carrier plate 1 through the sliding rod 4, so that the sliding rod 4 drives the U-shaped block 16 to move the pivot 17. Then, the pivot 17 drives the clamping block 11 to rotate through the T-shaped block 10 and squeezes the glass to fit and position it against the positioning block 12. The glass is then clamped and positioned between the positioning block 12 and the clamping block 11. Then, the residual stress detector 18 detects the glass surface and transmits the data to the control box 14. If it is necessary to disassemble the glass, refer to the above steps. After the clamping block 11 is separated from the glass surface, the glass can be removed from the top of the carrier plate 1. This realizes the quick clamping and positioning of the glass to be tested, so as to facilitate the disassembly and assembly of special glass, thereby improving the positioning efficiency during the testing of special glass.

[0025] In summary, this residual stress testing fixture for fatigue testing of special equipment achieves rapid clamping and positioning of the glass to be tested by placing the glass on top of the carrier plate 1, and then rotating the rotating plate 7 via the motor 3. The rotating plate 7 moves the fixed block 6 and the crossbar 5 via the connecting rod 8. The crossbar 5 then moves the U-shaped block 16 to move the pivot 17 via the slide rod 4. The pivot 17 then moves the clamping block 11 via the T-shaped block 10 to rotate and press the glass to fit against the positioning block 12. This allows for convenient assembly and disassembly of the special glass, resulting in better positioning efficiency during the testing of special glass.
