A bimetallic steel sleeve hardness detection device

Abstract

This utility model discloses a bimetallic steel sleeve hardness testing device, including a housing. A rotary motor is fixedly installed on the bottom surface of the housing. A first bearing is embedded in the inner bottom wall of the housing. A rotating rod is fixedly connected to the inner ring of the first bearing. The output end of the rotary motor is connected to the bottom end of the rotating rod through the first bearing. A first bevel gear is fixedly connected to the top end of the rotating rod. Two sets of second bearings are embedded in the inner wall of the housing. This device drives the rotating rod and the first bevel gear to rotate through the rotary motor, which in turn drives the meshing second bevel gear and the threaded rod to rotate. This causes the moving plates on both sides to move the arc plates towards each other, achieving stable clamping of the steel sleeve. The electric push rod in the fixed frame drives the lifting frame to move up and down, which can adjust the height of the lifting frame to adapt to metal steel sleeves of different heights. This device solves the problem that the metal steel sleeve may shift at the moment the pressure head applies pressure, affecting the test data.

Description

Technical Field

[0001] This utility model relates to the field of metal sleeve testing technology, and in particular to a bimetallic sleeve hardness testing device. Background Technology

[0002] Metal sleeves are metal products made of high-quality steel and are widely used in machinery, automobiles, petroleum, chemical, power, construction and other fields. They are mainly used as wear-resistant, corrosion-resistant and high-strength materials, and can also be used as precision parts to improve the performance of equipment. Usually, in order to ensure the quality of metal sleeves, hardness testing is required to determine their performance.

[0003] Existing hardness testing equipment typically places a metal sleeve vertically onto a support platform and then uses an indenter to perform hardness testing. Since the contact between the metal sleeve and the support platform relies solely on simple placement, the metal sleeve may shift when pressure is applied by the indenter, affecting the test data. To address this issue, we propose a bimetallic sleeve hardness testing device. Utility Model Content

[0004] The purpose of this invention is to provide a bimetallic steel sleeve hardness testing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bimetallic steel sleeve hardness testing device includes a housing. A rotary motor is fixedly installed on the bottom surface of the housing. A first bearing is embedded in the inner bottom wall of the housing. A rotating rod is fixedly connected to the inner ring of the first bearing. The output end of the rotary motor is connected to the bottom end of the rotating rod through the first bearing. A first bevel gear is fixedly connected to the top end of the rotating rod. Two sets of second bearings are embedded in the inner wall of the housing. A threaded rod is fixedly connected to the inner ring of each of the two sets of second bearings. A second bevel gear is connected to the end of each of the two sets of threaded rods that is close to each other. Both sets of second bevel gears mesh with the first bevel gear. A movable plate is threadedly connected to the outer surface of each of the two sets of threaded rods. Two sets of movable openings are opened on the upper surface of the housing. A bearing assembly is provided on the upper surface of the housing. The movable openings and the bearing assembly are sequentially passed through the upper surfaces of the two sets of movable plates. An arc plate is connected to the side of each of the two sets of movable plates that is close to each other. A fixed frame is fixedly connected to the outer surface of the housing. An electric push rod is fixedly installed inside the fixed frame. A lifting frame is fixedly connected to the output end of the electric push rod. A measuring component is provided on the bottom surface of the lifting frame.

[0007] In a further embodiment, the support assembly includes a support platform, and two sets of pressure sensors are fixedly connected to the bottom surface of the support platform. The bottom surfaces of the two sets of pressure sensors are connected to the upper surface of the housing.

[0008] In a further embodiment, the measuring component includes a hydraulic rod located on the upper surface of the lifting frame, the output end of the hydraulic rod passing through the lifting frame and extending to the bottom surface of the lifting frame, the output end of the hydraulic rod being fixedly connected to a mounting plate, and a pressure head being fixedly connected to the bottom surface of the mounting plate.

[0009] In a further embodiment, two sets of support plates are fixedly connected to the inner bottom wall of the outer shell, and a third bearing is embedded inside each of the two sets of support plates. The inner rings of the two sets of third bearings are connected to the outer surface of the threaded rod.

[0010] In a further embodiment, the inner bottom wall of the outer shell is provided with two sets of limiting grooves, and the inner walls of the two sets of limiting grooves are slidably connected to the outer surface of the movable plate.

The sides of the two sets of sliders that are close to each other are connected to the outer surface of the lifting frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device drives a rotating rod and a first bevel gear to rotate via a rotary motor, which in turn drives a second bevel gear and a threaded rod to rotate. This causes the moving plates on both sides to move the arc plates towards each other, achieving stable clamping of the bimetallic steel sleeve. The electric push rod in the fixed frame drives the lifting frame to move up and down, allowing the height of the lifting frame to be adjusted to fit metal sleeves of different heights. This device solves the problem that the metal sleeve may shift at the moment the pressure head applies pressure, affecting the test data. Attached Figure Description

[0024] Please see Figure 1-5 In this utility model, a bimetallic steel sleeve hardness testing device includes a housing 1. A rotary motor 6 is fixedly installed on the bottom surface of the housing 1. A first bearing 7 is embedded in the inner bottom wall of the housing 1. A rotating rod 8 is fixedly connected to the inner ring of the first bearing 7. The output end of the rotary motor 6 is connected to the bottom end of the rotating rod 8 through the first bearing 7. A first bevel gear 9 is fixedly connected to the top end of the rotating rod 8. Two sets of second bearings 13 are embedded in the inner wall of the housing 1. Threaded rods 14 are fixedly connected to the inner rings of both sets of second bearings 13. A second bevel gear 15 is connected to the end of each set of threaded rods 14 that is close to each other. Both sets of second bevel gears 15 mesh with the first bevel gear 9. Moving plates 12 are threadedly connected to the outer surfaces of both sets of threaded rods 14. Two sets of movable openings 11 are provided on the upper surface of the housing 1. The upper surfaces of the two sets of movable plates 12 are connected to the movable opening 11 and the carrier component 2 in sequence. The sides of the two sets of movable plates 12 that are close to each other are connected to arc plates 18. The outer surface of the outer shell 1 is fixedly connected to the fixed frame 3. The inside of the fixed frame 3 is fixedly installed with an electric push rod 10. The output end of the electric push rod 10 is fixedly connected to the lifting frame 4. The bottom surface of the lifting frame 4 is provided with a measuring component 5. Through the cooperation of the rotary motor 6, the first bevel gear 9, the second bevel gear 15, the threaded rod 14 and the movable plate 12, the two sets of arc plates 18 can be moved closer or further apart to fix the steel sleeve. Through the cooperation of the fixed frame 3, the electric push rod 10 and the lifting frame 4, the measuring component 5 can be moved up and down to approach the steel sleeve. The movable opening 11 facilitates the movement of the movable plate 12.

[0025] The bearing assembly 2 includes a bearing platform 201. Two sets of pressure sensors 202 are fixedly connected to the bottom surface of the bearing platform 201. The bottom surfaces of the two sets of pressure sensors 202 are connected to the upper surface of the outer shell 1. The pressure on the bearing platform 201 is monitored in real time by the pressure sensors 202, thereby detecting the hardness of the steel sleeve.

[0026] The measuring component 5 includes a hydraulic rod 501, which is located on the upper surface of the lifting frame 4. The output end of the hydraulic rod 501 passes through the lifting frame 4 and extends to the bottom surface of the lifting frame 4. The output end of the hydraulic rod 501 is fixedly connected to a mounting plate 502. A pressure head 503 is fixedly connected to the bottom surface of the mounting plate 502. The hydraulic rod 501 drives the pressure head 503 to move downward through the mounting plate 502, which can apply pressure to the steel sleeve.

[0027] Two sets of support plates 16 are fixedly connected to the inner bottom wall of the outer casing 1. Each set of support plates 16 has a third bearing 17 embedded inside. The inner rings of the two sets of third bearings 17 are connected to the outer surface of the threaded rod 14. Through the cooperation of the support plates 16 and the third bearings 17, the threaded rod 14 can be supported, thereby improving the load-bearing capacity of the threaded rod 14.

[0028] The inner bottom wall of the outer casing 1 is provided with two sets of limiting grooves 19. The inner walls of the two sets of limiting grooves 19 are slidably connected to the outer surface of the movable plate 12. By sliding the movable plate 12 in the limiting grooves 19, the movable plate 12 can be limited and guided.

[0029] The two sets of arc plates 18 are fixedly connected to protective pads 20 on their close sides. Both sets of protective pads 20 are made of rubber. By providing protective pads 20, not only is the clamping stability enhanced, but the surface of the steel sleeve is also prevented from being pinched.

[0030] The outer surface of the fixed frame 3 is provided with symmetrical sliding openings 22. Sliding sliders 21 are slidably connected inside the two sliding openings 22. The sides of the two sets of sliding sliders 21 that are close to each other are connected to the outer surface of the lifting frame 4. By sliding the sliding sliders 21 in the sliding openings 22, the lifting height of the lifting frame 4 can be limited.

[0031] The working principle of this utility model is as follows:

[0032] During use, the rotary motor 6 drives the first bevel gear 9 to rotate, the rotating first bevel gear 9 drives the second bevel gear 15 to rotate, the rotating second bevel gear 15 drives the threaded rod 14 to rotate, and the rotating threaded rod 14 drives the moving plate 12 to move closer to each other, so that the moving plate 12 drives the arc plate 18 to clamp the metal steel sleeve on the support platform 201. Then, the electric push rod 10 drives the lifting frame 4 to move downward, so that the pressure head 503 approaches the top surface of the steel sleeve. Then, the hydraulic rod 501 drives the pressure head 503 to move downward through the mounting plate 502, applying pressure to the steel sleeve. At the same time, the pressure sensor 202 monitors the pressure on the support platform 201 in real time, thereby detecting the hardness of the steel sleeve.
