Description

[0002] At present, regarding the relevant simulation test machines of reciprocating friction and wear testers, when designing, the test box adopts a sealed structure design, and uses a heating device to simulate the wear of test materials under different oil well oil and temperature conditions.

[0033] The core of the utility model is to provide a material wear test device, which can have a good cooling effect under high-speed friction conditions and can simulate erosion wear.

[0034] Please refer to Figures 1-4 A material wear experimental device includes a grinding component 1 and a spray component 2. The grinding component 1 includes a mounting plate 101 and a grinding column 102.

The spray component 2 includes a nozzle 201 for spraying toward the contact position between the grinding column 102 and the grinding disc 104, and a pump body 202 connected with the nozzle 201.

[0035] It should be noted that the present invention does not limit the specific structure of the driver 108. In some embodiments, the driver 108 is a motor, such as a DC brushed motor or a stepper motor. In this embodiment, the driver 108 is a brushless motor.

[0036] In addition, the embodiment of the present invention is not limited to the installation method between the main shaft 103 and the grinding disc 104. In some embodiments, the main shaft 103 and the grinding disc 104 can be fixedly connected by welding, and in other embodiments, a detachable connection is achieved by bolts.

[0037] In some embodiments, a frame 3 is also included, and the grinding assembly 1 and the spray assembly 2 are both installed on the frame 3. A control box 4 is provided on the frame 3, and a display is provided on the control box 4 for displaying experimental related data. At the same time, the electrical components of the device can be controlled by the display and the control box 4. This part will not be repeated.

[0038] In addition, the embodiment of the present invention does not limit the grinding method between the grinding column 102 and the grinding disc 104 .

[0039] In some embodiments, the grinding column 102 and the grinding disc 104 may be arranged vertically, that is, the axes of the grinding column 102 and the grinding disc 104 may be arranged parallel to each other, and the wear test may be achieved by contact between the end of the grinding column 102 and the plane of the grinding disc 104.

[0040] In other embodiments, the diameters of the grinding cylinder 102 and the grinding disk 104 may be arranged parallel to each other, and the wear test may be performed by contact between the end of the grinding cylinder 102 and the side of the grinding disk 104 .

[0041] In addition, the embodiment of the present invention does not limit the method of replacing the experimental materials of the grinding column 102 and the grinding disc 104.

[0042] In some embodiments, the wear tests on different materials can be carried out by disassembling and replacing the grinding cylinder 102 and the grinding disc 104 made of different materials.

[0043] In other embodiments, the material to be tested can be placed on the grinding column 102 and the grinding disc 104 respectively on the contact surface of the grinding column 102 and the grinding disc 104 through surface modification technology, surface alloying technology, surface coating technology or electrochemical treatment process, so as to complete the wear test of the required material.

[0044] During use, the main shaft 103 is mounted on the mounting plate 101, and the grinding disc 104 is mounted on the main shaft 103. At the same time, when the grinding column 102 is in contact with the grinding disc 104, a grinding experiment is carried out. A driving member 108 for driving the grinding disc 104 is also installed on the mounting plate 101. That is to say, the grinding disc 104 is driven by the driving member 108 to rotate at a high speed, so that friction is generated between it and the grinding column 102 to achieve the purpose of the wear test. The spray assembly 2 includes a nozzle 201 for spraying toward the contact position between the grinding column 102 and the grinding disc 104 and a pump body 202 connected to the nozzle 201. The coolant or erosion liquid is sprayed toward the contact position between the grinding column 102 and the grinding disc 104 through the pump body 202 to achieve the purpose of cooling the grinding position, avoid high temperature during the experiment, and affect the experimental results. The scouring of the fluid is used to achieve experimental effects such as scouring wear and corrosive wear, which can ensure the safety and reliability of the experiment and improve the accuracy of the experimental results.

[0045] Please refer to Figure 1 In order to avoid the danger caused by the splashing of debris generated during the experiment, in some embodiments, the mounting plate 101 is provided with a shell 105 for placing the grinding disc 104 inside, and the shell 105 is provided with an opening, that is, the shell 105 and the mounting plate 101 form a cavity for placing the grinding disc 104 and the grinding column 102 inside, so as to reduce the danger caused by the splashing of debris during the experiment and help reduce the pollution to the experimental environment.

[0046] It should be noted that the housing 105 of the embodiment of the present invention can be integrally formed with the mounting plate 101 .

[0047] In addition, an opening is provided on the shell 105 to facilitate replacement of the grinding disc 104 and the grinding column 102. In order to prevent debris from flying out through the opening, in some embodiments, a cover is hinged at the opening of the shell 105, that is, the opening is closed by the cover and is only opened when replacement is required.

[0048] It should be noted that, in the embodiment of the present invention, the hinge between the cover plate and the housing 105 is located at the upper edge of the cover plate, that is, the cover plate can automatically close the opening by the weight of the cover plate itself.

[0049] In addition, the hinge between the cover plate and the housing 105 may also be located on the side of the cover plate. In this case, by installing a torsion spring at the hinge between the cover plate and the housing 105, the cover plate can automatically close the opening.

[0050] Please continue to refer to Figure 4 In order to avoid the contamination of the experimental environment by the spray liquid and to reuse the spray liquid, in some embodiments, the shell 105 and the mounting plate 101 form a liquid collecting tank 106 located below the grinding disc 104, and the pump body 202 is connected to the liquid collecting tank 106 through a pipeline. That is to say, the spray liquid will eventually be collected by the liquid collecting tank 106 and then circulated through the pump body 202 to achieve the reuse of the spray liquid and reduce the cost of the experiment.

[0051] It should be noted that the liquid collecting tank 106 in the embodiment of the present invention is a space formed between the shell 105 and the mounting plate 101, and when the cover is closed, a closed space is formed inside it, which minimizes the environmental pollution and noise pollution of the experiment.

[0052] In addition, in order to further prevent the spray liquid from damaging the pump body 202 during the reuse process, a filtering structure can be set inside the liquid collection tank 106. The filtering structure is a filter plate made of filter material. The filter plate is placed inside the liquid collection tank 106 and above the connection position between the pump body 202 and the liquid collection tank 106. Therefore, when the spray liquid enters the liquid collection tank 106, it will be filtered under the action of the filter plate, thereby preventing debris generated during the experiment from damaging the pump body 202 during circulation.

[0053] Please refer to Figure 1 In order to further improve the rotational balance of the grinding disc 104 during the experiment, in some embodiments, the grinding disc 104 is provided with a plurality of through holes 107 distributed along the circumference of its axis, and a plurality of counterweights are detachably installed on the grinding disc 104 through the through holes 107. That is to say, the counterweights are installed and removed through the through holes 107 to try to distribute the weight at different positions on the grinding disc 104, thereby improving the dynamic balance of the grinding disc 104 during rotation and further improving the accuracy of the experimental results.

[0054] It should be noted that, in the embodiment of the present invention, the through holes 107 are divided into several groups, each group has several through holes 107, and the through holes 107 in each group are distributed in a circular array along the axis of the grinding disc 104, and the diameter of the circular ring formed by the several groups of through holes 107 gradually increases.

[0055] Please refer to Figure 2 In order to enable the device to adjust the distance between the grinding column 102 and the grinding disc 104 according to the needs of the experiment, in some embodiments, a push plate 5 is installed on the frame 3, and the grinding column 102 is detachably installed on the push plate 5. The shell 105 is provided with a grinding opening for the grinding column 102 to extend into the interior of the shell 105, and the frame 3 is provided with a pushing member 8 for controlling the push plate 5 to move along the axial direction of the grinding column 102. That is to say, the push plate 5 and the grinding column 102 are driven to move by the pushing member 8, so as to realize automatic feeding of materials during the wear test and ensure the effectiveness of the experiment.

[0056] It should be noted that the embodiment of the present utility model does not limit the specific structure of the pushing member 8.

[0057] In some embodiments, the pushing member 8 is a hydraulic cylinder, and the movement of the push plate 5 along the axis of the grinding column 102 is controlled by the extension and contraction of the hydraulic cylinder.

[0058] In other embodiments, the pushing member 8 is an electric cylinder, and the movement of the push plate 5 along the axis of the grinding column 102 is controlled by the extension and contraction of the electric cylinder.

[0059] In other embodiments, the pusher 8 is a screw slider structure, which drives the screw to rotate through a motor and causes the slider to slide along the screw, thereby controlling the push plate 5 to move along the axis of the grinding column 102.

[0060] In addition, the pushing member 8 in this embodiment can also be replaced by an electric cylinder.

[0061] Please refer to Figure 2 In order to ensure the stability of the push plate 5 during movement, in some embodiments, a limit rod 7 is fixed on the frame 3 and is arranged parallel to the axis of the grinding column 102. The push plate 5 and the limit rod 7 are slidably matched. That is, the limit rod 7 limits the push plate 5 to prevent the push plate 5 from bending during movement, thereby ensuring effective contact between the grinding column 102 and the grinding disc 104.

[0062] Please refer to Figure 2 In order to facilitate the disassembly of the grinding column 102, in some embodiments, the push plate 5 is provided with a mounting sleeve 6 for fixing the grinding column 102. That is to say, by placing the grinding column 102 inside the mounting sleeve 6, the installation of the grinding column 102 can be achieved, and disassembly is also extremely convenient.

[0063] It should be noted that, in the embodiment of the present invention, the grinding column 102 and the mounting sleeve 6 are fixed by interference fit.

[0064] In other embodiments, a through hole 107 is opened on the side of the mounting sleeve 6, and a threaded hole matching the through hole 107 is opened on the grinding column 102, and the grinding column 102 is installed and fixed by screwing bolts.

[0065] That is to say, the focus of the embodiment of the present invention is that the main shaft 103 is installed on the mounting plate 101, and the grinding disc 104 is installed on the main shaft 103, and at the same time, the grinding column 102 is brought into contact with the grinding disc 104 to carry out a grinding experiment. The mounting plate 101 is also provided with a driving member 108 for driving the grinding disc 104, that is, the driving member 108 drives the grinding disc 104 to rotate at a high speed, so that friction is generated between it and the grinding column 102, so as to achieve the purpose of the wear test. The spray assembly 2 includes a nozzle 201 for spraying toward the contact position between the grinding column 102 and the grinding disc 104 and a pump body 202 connected to the nozzle 201. The pump body 202 sprays the coolant or the erosion liquid toward the contact position between the grinding column 102 and the grinding disc 104, so as to achieve the purpose of cooling the grinding position, avoid high temperature during the experiment, and affect the experimental results. The erosion of the fluid is used to achieve experimental effects such as erosion wear and corrosion wear, which can ensure the safety and reliability of the experiment and improve the accuracy of the experimental results.
