Technical Field

[0001] This utility model belongs to the field of testing device technology, specifically a steel ball impact resistance testing device. Background Technology

[0002] After hot-rolled wear-resistant steel balls are manufactured, they usually need to be sampled and tested according to batch. Impact resistance testing is carried out by using an impact resistance testing device to provide key data support for production process optimization and quality control.

[0003] Existing steel ball impact resistance testing devices typically involve fixing the steel ball and using a reciprocating impact hammer to repeatedly impact it in the test direction. After the reciprocating impact, the deformation of the steel ball is visually and determined by a laser detector to assess its impact resistance. However, the actual deformation is difficult to detect and assess, and laser detection is costly. There is a lack of a simple and intuitive testing method. Utility Model Content

[0004] The purpose of this invention is to provide a steel ball impact resistance 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: a steel ball impact resistance testing device, comprising a testing seat and a testing upper arm fixed above the testing seat. The top of the testing seat has a pre-reserved groove, and the interior of the testing seat has a liquid storage chamber communicating with the pre-reserved groove. An elastic membrane is fixedly connected inside the liquid storage chamber. A testing observation part is fixedly provided on the top of the testing seat, and a curved hole communicating with the testing observation part and the liquid storage chamber is provided inside the testing seat. Clamping and flipping mechanisms are provided on both sides of the testing seat, and these mechanisms control the steel ball being tested to flip up and down. The detection and observation section includes a transparent graduated tube, a piston rod, and a spring. The transparent graduated tube is connected to a curved hole. One end of the piston rod is movably sleeved in the transparent graduated tube, and the inner end of the piston rod is fixedly connected to the spring, which is also fixedly connected in the transparent graduated tube.

[0006] Preferably, the detection arm includes a hydraulic lifting mechanism and a hammer column, wherein the hydraulic lifting mechanism controls the hammer column to reciprocate downward and reciprocate to impact a steel ball fixed on the top of the detection seat.

[0007] Preferably, the clamping and flipping mechanism includes a clamping assembly and a flipping drive assembly, with the two clamping assemblies clamping the steel ball and the flipping drive assembly controlling the rotation of the clamping assembly.

[0008] Preferably, the clamping assembly includes an electric push rod, a connecting frame, an elastic clamping seat, and a through hole. The elastic clamping seat is fixed to the end of the connecting frame, and the through hole passes through the elastic clamping seat and communicates with the interior of the connecting frame. The movable end of the electric push rod is fixedly connected to the connecting frame.

[0009] Preferably, a negative pressure control mechanism is provided on one side of the connecting frame. The negative pressure control mechanism draws air from inside the connecting frame, so that the clamped steel ball is simultaneously adsorbed and fixed in the middle of the clamping assembly.

[0010] Preferably, the negative pressure control mechanism includes a connecting sleeve, a piston plate, and an electric push rod three. The connecting sleeve is connected to the side of the connecting frame, the piston plate is movably sleeved inside the connecting sleeve, and one end of the electric push rod three moves through the connecting sleeve and is fixedly connected to the piston plate. The electric push rod three drives the piston plate to draw air from the connecting frame in the connecting sleeve.

[0011] Preferably, the flipping drive assembly includes a mounting sleeve, a gear, a toothed plate, and a second electric push rod.

The second electric push rod is fixed to the side of the detection seat via a bottom support frame. The toothed plate is fixedly connected to the movable end of the second electric push rod.

[0012] The beneficial effects of this utility model are as follows: (1) This utility model utilizes a liquid storage chamber, an elastic membrane, and a detection and observation section to nest a steel ball in the liquid storage chamber before impact testing. The liquid level in the detection and observation section is recorded by pressing the elastic membrane. After impact treatment, the impact area is rotated downwards, and the steel ball is flipped over to compress the liquid in the storage chamber. By observing the change in liquid level in the detection and observation section before and after flipping, it is determined whether there is a depression or deformation in the impact area of ​​the steel ball. When the liquid level decreases before and after, it is determined that there is deformation due to impact. The liquid level difference reflects the degree of depression, and thus reflects the degree of deformation under impact. This simple and convenient method completes the intuitive detection of the impact resistance performance of the steel ball.

[0013] (2) This utility model utilizes a negative pressure control mechanism set on the outside of the clamping assembly. After clamping and fixing the steel balls on both sides, it further reduces the air pressure in the clamping assembly. With the through hole opened on the elastic clamping seat and connected to the connecting frame, after the through hole is sealed by the steel ball, the pressure difference established achieves the auxiliary adsorption and fixing of the steel ball. At the same time as clamping on both sides, adsorption and fixing are carried out, which improves the stability of the steel ball impact, avoids the deviation of the continuous impact area caused by the cheapness, ensures that the continuous impact is in the same area, and facilitates the detection of the local impact resistance performance of the steel ball under continuous impact.

[0019] The bottom of the hammer-shaped column has a rounded surface, which provides impact stability and avoids deformation of sharp edges.

[0020] The clamping and flipping mechanism includes a clamping assembly 8 and a flipping drive assembly 10. The two clamping assemblies 8 clamp the steel ball, and the flipping drive assembly 10 controls the rotation of the clamping assembly 8. The clamping assembly 8 includes an electric push rod 81, a connecting frame 82, an elastic clamping seat 83, and a through hole 84. The elastic clamping seat 83 is fixed to the end of the connecting frame 82, and the through hole 84 passes through the elastic clamping seat 83 and communicates with the interior of the connecting frame 82. The movable end of the electric push rod 81 is fixedly connected to the connecting frame 82. A negative pressure control mechanism 11 is provided on one side of the connecting frame 82. The negative pressure control mechanism 11 draws air from the inside of the connecting frame 82, so that the clamped steel ball is simultaneously adsorbed and fixed in the middle of the clamping assembly 8.

[0021] The clamping assembly 8 clamps the steel ball by abutting from both sides, and the elastic clamping seat 83 deforms elastically to adapt to the outer arc surface of the steel ball, increasing the contact area and providing fixation stability.

[0022] The negative pressure control mechanism 11 includes a connecting sleeve 111, a piston plate 112, and an electric push rod 113. The connecting sleeve 111 is connected to the side of the connecting frame 82. The piston plate 112 is movably sleeved inside the connecting sleeve 111. One end of the electric push rod 113 moves through the connecting sleeve 111 and is fixedly connected to the piston plate 112. The electric push rod 113 drives the piston plate 112 to draw air from the connecting frame 82 in the connecting sleeve 111.

[0023] The negative pressure control mechanism 11 reduces the air pressure in the connecting frame 82 to achieve auxiliary adsorption and fixation of the steel ball under the action of pressure difference.

[0024] The flip drive assembly 10 includes a mounting sleeve 101, a gear 102, a toothed plate 103, and an electric push rod 104. A support platform 9 is fixedly provided on the top of the detection seat 1. The mounting sleeve 101 is rotatably mounted in the support platform 9 through a bearing. One end of the electric push rod 101 is fixedly nested in the mounting sleeve 101. The gear 102 is fixedly sleeved on the outside of the mounting sleeve 101. The toothed plate 103 is meshed with the gear 102. The electric push rod 104 is fixed to the side of the detection seat 1 through a bottom support frame. The toothed plate 103 is fixedly connected to the movable end of the electric push rod 104.

[0025] The flip drive assembly 10 controls the rotation of the mounting sleeve 101 through the meshing of the gear 102 and the toothed plate 103, thereby realizing the rotation of the clamping assembly 8 and controlling the steel ball to flip precisely. The top of the support frame is provided with a sliding groove, and the bottom of the toothed plate 103 is provided with a slider. Stable sliding control is maintained through the sliding groove and the slider.

[0026] The working principle and usage process of this utility model are as follows: The steel ball to be tested is placed in the reserved groove 3 at the top of the testing seat 1, and the bottom of the steel ball is nested in the liquid storage cavity 4 and the elastic membrane 5 is pressed by gravity, so that the elastic membrane 5 is stretched and attached to the bottom of the steel ball, and the internal liquid is compressed. The liquid level changes in the detection observation part 7 connected through the curved hole 6 are recorded by the transparent scale tube 71. The clamping components 8 on both sides are activated. The electric push rod 1 81 drives the connecting frame 82 and the elastic clamping seat 83 to move synchronously and press against the outside of the steel ball to complete the initial clamping and fixing. Then, the electric push rod 3 113 in the negative pressure control mechanism 11 is activated, which drives the piston plate 112 to slide in the connecting sleeve 111, sucking the air inside the connecting frame 82 and establishing negative pressure, so that the steel ball blocking the through hole 84 is adsorbed and fixed on the elastic clamping seat 83 to complete the auxiliary clamping. The detection upper arm 2 is activated, and the hammer column in the detection upper arm 2 reciprocates to impact the top of the steel ball. After a period of impact treatment, the flipping drive component 1 is activated. 0. The electric push rod 104 controls the movement of the toothed plate 103 and drives the meshing gear 102 to rotate, thereby driving the mounting sleeve 101 to rotate. This causes the clamping assembly 8 installed inside the mounting sleeve 101 to rotate 180°, thus causing the area after the top impact treatment to flip downward and press down the elastic membrane 5. When the steel ball impact detection area shows a dented deformation, the piston rod 72 in the detection observation part 7 acts on the top of the liquid surface through the elastic action of the spring 73, giving the liquid downward pressure. This increases the liquid pressure in the storage chamber 4 through the curved hole 6, and the liquid pressure causes the elastic membrane 5 at the dented area of ​​the steel ball to deform and adhere to the dented area, increasing the internal volume of the storage chamber 4. The increase is due to the dented volume of the steel ball. The liquid in the detection observation part 7 is used to compensate and fill the storage chamber 4, lowering the liquid level. The change in liquid level before and after is observed to quantify the deformation and complete the impact detection. That is, when the liquid level changes before and after, an impact dent occurs. The greater the change in liquid level, the greater the impact dent, and the worse the impact resistance of the steel ball.
