Technical Field
[0001] The utility model relates to the technical field of factory inspection of rotor seats, and specifically relates to a device for detecting the surface hardness of rotor seats. Background Technique
[0002] A device for detecting the surface hardness of a rotor seat is a device used to detect the surface hardness of a rotor seat (usually a rotor component in mechanical equipment such as generators, pumps or motors). This device is crucial in the industrial field because it can ensure that the hardness of the rotor seat material meets the design requirements, thereby guaranteeing the working performance and service life of the mechanical equipment. Currently, during the factory process of the rotor seat, a hardness detection device is used to perform hardness detection on the surface of the rotor seat. Since during the hardness detection process of the rotor seat, if the surface hardness at one place is detected to be qualified, it cannot guarantee that the overall surface hardness of the rotor seat reaches the qualified standard. Therefore, during the hardness detection process of the rotor seat, it is necessary to continuously adjust the surface of the rotor seat to perform hardness detection on the surfaces of different regions of the rotor seat. Usually, when adjusting the surface of the rotor seat, when it comes to the operation of relevant technical personnel, on the one hand, it increases the workload and work intensity of the relevant technical personnel, and on the other hand, it also increases the investment in personnel costs, thereby reducing the use effect of the device for detecting the surface hardness of the rotor seat and indirectly affecting the detection efficiency of the surface hardness of the rotor seat.
[0003] Therefore, it is necessary to develop a device for detecting the surface hardness of rotor seats. Content of the Utility Model

The pass / fail standard is determined based on whether the rotor seat is damaged. After the hardness test of one surface of the rotor seat, a set of rotating rollers can rotate the rotor seat to adjust it to another surface for another hardness test. This process requires no technical personnel, reducing workload and labor costs, effectively improving the performance of the rotor seat surface hardness testing device and indirectly increasing the testing efficiency.

Left and right threaded rods 2 are rotatably connected to the upper part of the worktable 1. Moving blocks 201 are threadedly connected to both sides of the outer wall of the left and right threaded rods 2. A motor 202 is installed on one side of the outer wall of the worktable 1. The output shaft of the motor 202 is fixedly connected to one end of the left and right threaded rods 2 via a coupling. Moving seats 3 are installed on both sides of the center of the top of the worktable 1. Guide blocks 301 are installed at the bottom of the moving seats 3. The outer wall of the guide block 301 is slidably connected to the inner wall of the guide groove 101. The two sets of moving seats 3 are slidably set in the guide groove 101 on the worktable 1 by the guide blocks 301, and the bottom of the guide blocks 301 is fixed to the top of the moving blocks 201. The moving block 201 is set on the outer wall of the left and right threaded rods 2 by a threaded connection. According to the left and right threaded rods 2, the left and right threaded rods 2 are driven by the motor 202 to rotate forward or reverse, which can simultaneously drive the two sets of moving seats 3 to move outward or inward. A positioning clamp 302 is installed on the upper side of one outer wall of the moving seat 3. A ball bearing 303 is rotatably connected on the inner wall of one side of the positioning clamp 302. The ball bearing 303 is rotatably connected on the inner wall of the positioning clamp 302 on the moving seat 3, so that the rotor seat that needs to be tested for hardness is placed on the surface of the pressure sensor 102 on the worktable 1. The two sets of moving seats 3 are driven by the motor 202 to clamp the rotor seat. The setting of the ball bearing 303 ensures that the fixed rotor seat can be rotated.
[0024] An operating frame 4 is mounted on the top of the workbench 1. A hydraulic cylinder 401 is mounted on the top of the operating frame 4. A movable frame 5 is mounted inside the upper part of the operating frame 4. The top center of the movable frame 5 is fixedly connected to the output end of the hydraulic cylinder 401. Guide columns 501 are mounted on both sides of the top of the movable frame 5. The outer wall of the guide columns 501 is slidably connected to the inside of the operating frame 4. A pressure seat 502 is mounted at the bottom center of the movable frame 5. Mounting holes 503 are opened on both sides of the surface of the movable frame 5. Limiting columns 504 are slidably connected inside the mounting holes 503. A limiting ring 505 is set at the top of the limiting column 504. A roller 506 is mounted at the bottom of the limiting column 504. A spring 507 is set on the outer wall of the limiting column 504. The movable frame 5 is mounted and fixed at the output end of the hydraulic cylinder 401 on the operating frame 4. The limiting columns 504 on the two sets of rollers 506 are slidably connected to the mounting holes 503 on the movable frame 5. Any set of rollers 506 can be selected. A motor is installed at position 06 to drive the control roller 506 to rotate. A spring 507 is fitted on the outer wall of the limit post 504, and a pressure seat 502 is installed at the bottom of the moving frame 5. When the roller 506 in the reset state is lower than the pressure seat 502, the hydraulic cylinder 401 lowers the pressure seat 502. The roller 506 is in pre-contact with the upper surface of the rotor seat. The hydraulic cylinder 401 lowers again until the pressure seat 502 performs a hardness test on the surface of the rotor seat. When the pressure detected by the pressure sensor 102 reaches the qualified standard, the hydraulic cylinder 401 can be stopped from continuing to descend. The qualified standard is determined based on whether the rotor seat is damaged. After the hardness test of one surface of the rotor seat is completed, a set of rotating rollers 506 can rotate the rotor seat to adjust it to other surfaces for another surface hardness test. During this process, no relevant technical personnel are required to operate, reducing the workload and labor intensity of personnel involved, and also reducing personnel costs.
[0025] Working principle: When using this utility model, two sets of movable seats 3 are slidably set in the guide groove 101 on the worktable 1 by guide blocks 301, and the bottom of the guide blocks 301 is fixed to the top of the movable blocks 201, so that the movable blocks 201 are set on the outer wall of the left and right threaded rods 2 by threaded connection. According to the left and right threaded rods 2 having left and right threads, the motor 202 drives the left and right threaded rods 2 to rotate forward or reverse, which can synchronously drive the two sets of movable seats 3 to move outward or inward synchronously. By using the positioning clamps on the movable seats 3 A ball bearing 303 is rotatably connected to the inner wall of fixture 302, allowing the rotor seat requiring hardness testing to be placed on the surface of pressure sensor 102 on workbench 1. Motor 202 drives two sets of moving seats 3 to clamp the rotor seat. The ball bearing 303 ensures that the fixed rotor seat can rotate. The moving frame 5 is mounted and fixed at the output end of hydraulic cylinder 401 on operating frame 4, and the limiting posts 504 on the two sets of rollers 506 are slidably engaged with the mounting holes 503 on the moving frame 5. The selection of the two sets of rollers 506... A motor is installed at any set of rollers 506, allowing the motor to drive and control the rotation of the rollers 506. A spring 507 is fitted onto the outer wall of the limiting post 504, and a pressure seat 502 is installed at the bottom of the moving frame 5. When the rollers 506 are in the reset state and lowered below the pressure seat 502, the hydraulic cylinder 401 lowers the pressure seat 502, causing the rollers 506 to pre-contact the upper surface of the rotor seat. The hydraulic cylinder 401 then lowers again until the pressure seat 502 performs a hardness test on the rotor seat surface. When the pressure detected by the pressure sensor 102 reaches the acceptable standard, the hydraulic cylinder 401 stops descending. The acceptable standard is determined based on whether the rotor seat is damaged. After the hardness of one surface of the rotor seat is tested, a set of rotating rollers 506 can rotate the rotor seat to adjust it to other surfaces for another surface hardness test. This process requires no technical personnel, reducing workload and labor costs, effectively improving the performance of the rotor seat surface hardness testing device, and indirectly improving the testing efficiency.
