Description
Technical Field
The invention relates to a detection device for detecting the wear resistance of a sample.
Background
Wear resistance refers to the ability of a material to resist wear under certain friction conditions. The phenomenon of abrasion is common, and the cause of the phenomenon is in physical chemistry and mechanical aspects, and mainly comprises abrasive wear, adhesive wear, fatigue wear and corrosion wear. The wear resistance is almost related to all properties of the material, and under different wear mechanism conditions, different requirements are also placed on the material properties for improving the wear resistance. Abrasion resistance in the coatings industry refers to the resistance of a coating to tribomechanical or physical effects. In fact, the comprehensive effects of hardness, adhesion and cohesion of the coating are reflected. Under the same conditions, the wear resistance of the coating is better than that of the metal material, and the coating can buffer, absorb and release energy due to the viscoelastic effect. Has protective effect on the metal material. Many products need to be in direct contact with users in the use process or repeatedly rub and contact other objects, and the repeated contact can cause surface abrasion of the products to influence the attractive appearance and even the service performance of the products, so that the surface abrasion resistance of the products is an important quality index, and the surface abrasion resistance of the products needs to be tested in the quality control process of the products. The multipurpose friction machine for testing the surface wear resistance can generate abrasion through friction with the test head, and the surface wear resistance of a product can be judged through calculating related data such as abrasion loss, abrasion depth and the like. The traditional test is difficult to simulate the actual working condition, so the reliability and the accuracy of the result are insufficient.
For example, the invention of the chinese utility model patent with application number 201320573663.3, published on 4/2/2014, is named as "an improved device for testing wear resistance of plating layer", and includes a frame, a case holding device, and a plurality of roller sets disposed on one side of the frame, a fabric belt forms a closed loop around the roller sets, a to-be-tested case held by the case holding device contacts with the fabric belt, a control system is disposed above the frame, and the control system includes a control box, and a timer disposed on the control box.
The application is suitable for tribological performance tests of various covering layers such as electroplated layers, vacuum plating layers and the like. The test result of the plating layers with different hardness is obvious, the wear resistance of the plating layers is easy to distinguish, and the method has high reference value. The fabric belt is used as a friction material in the test, constant friction force is applied to the surface of a test piece, the fabric belt has good adaptability to the geometric shape of the work piece, and the wear resistance test can be performed on parts with complex shapes such as a watch case, a watch band and the like. However, the above patent application still has the following disadvantages:
the abrasion of a real working environment to a product cannot be completely simulated, for example, the influence of sand particles on the friction performance of a metal coating in abrasion environments such as sand-containing water or seawater and the like; different solutions also have influence on the friction performance of the metal coating at different temperatures; the stress angle of the test sample cannot be adjusted; the frictional properties of different stressed surfaces of the fabric belt cannot be tested.
For another example, the invention of the chinese utility model with application number 201420738034.6, published in 2015, 04, 15 and invented by the inventor is named as "a metal wear resistance testing device", which comprises a workbench, a sample fixing clamp and a testing head with height capable of being lifted, wherein the workbench is provided with a horizontal sliding rail and a hydraulic cylinder; the bottom of the sample fixing clamp is provided with a horizontal sliding chute matched with the horizontal sliding rail, and one side of the sample fixing clamp is fixedly connected with a piston rod of the hydraulic oil cylinder; a displacement sensor and a counter are arranged on the piston rod; the top of the test head is provided with a loading device; an annular liquid storage cylinder is sleeved on the outer side of the loading device, a plurality of spray holes are uniformly formed in the bottom of the liquid storage cylinder, and different solutions are stored in the liquid storage cylinder. Although the application solves the problem of test influence under the atmospheric condition and the solution not close to the working condition to a certain extent, the reliability and the test result are improved. However, the above patent application still has the following disadvantages:
the abrasion of a real working environment on a product cannot be completely simulated, for example, the influence of sand particles on the friction performance under the abrasion environment of sand-containing water or seawater and the like; the friction performance of the material is influenced by different solutions at different temperatures; the stress angle of the test sample cannot be adjusted; the friction performance of different stress surfaces of the sample cannot be tested; and a plurality of samples cannot be tested simultaneously, and the testing efficiency is low due to long testing time.

With the above configuration, the sample to be detected can be relatively moved with respect to the fluid and at least a part of the sample to be detected is continuously kept in contact with the fluid during the relative movement, so that the influence of the fluid on the wear resistance of the material of the sample to be detected can be simulated on at least a part of the sample to be detected. In addition, by introducing different fluids, such as pure water, sand-containing water, salt water (such as seawater), organic solution and the like into the fluid space, the influence relationship on the wear resistance under different environmental influence factors can be simulated, so that the wear resistance of the material of the detected sample can be detected more reliably and accurately.

In addition, when at least one detected sample is a plurality of detected samples, a plurality of detected samples can be detected in the detection device at the same time, so that the detection efficiency is greatly improved.
Preferably, the device for detecting the wear resistance of the sample according to the present invention further comprises a turntable disposed inside the inner housing and a rotating shaft for driving the turntable to rotate; the sample fixing clamp is rotatably arranged on the turntable.

Detailed Description
In order to make the purpose and technical solution of the embodiments of the present invention clearer, the technical solution of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention without any inventive step, are within the scope of protection of the invention.
Fig. 1 is a schematic view of a test apparatus for testing wear resistance of a sample according to a first embodiment of the present invention. The inspection apparatus includes an inner housing 1 and a sample fixing jig 2. The inner housing 1 defines a fluid space therein and is capable of containing a predetermined amount of fluid, subject to the capability of submerging at least a portion of a sample under test 3 (as an example of a sample under test) described below. In the present embodiment, the inner housing 1 includes a base 10, and an upper surface of the base 10 serves as a bottom surface 10a of the inner housing 1. In the present embodiment, the fluid includes pure water, water containing sand, brine (e.g., seawater), an organic solution, and the like. Further, the fluid space may be a closed space to prevent leakage of the fluid contained therein. However, it should be understood that the fluid space need not be closed, so long as a predetermined amount of fluid can be contained.
The detection device also comprises a rotating disc 14 arranged in the inner shell 1 and a rotating shaft 11 driving the rotating disc 14 to rotate, one end of the rotating shaft 11 is connected to the rotating disc 14, the other end is positioned at the opposite side of the one end relative to the base 10 and is connected with a motor 13 through a belt 12, and the rotating speed of the rotating shaft is controlled by the motor 13. The turntable 14 is cylindrical in shape. However, it is understood that the turntable 14 may be other shapes.
A sample holding fixture 2 is located in the fluid space. The sample fixing jig 2 is plural. However, it is understood that the sample holding jig 2 may be one. Further, in the present embodiment, a plurality of sample fixing jigs 2 are arranged on the turntable 14. Each sample holding jig 2 includes a pallet-shaped jig base 2 b.
As shown in fig. 1 and 2, a sample 3 to be tested is fixed on a sample fixing jig 2. In the present embodiment, the test sample 3 is also plural and box-shaped. Specifically, each of the samples 3 to be tested is fixed to the corresponding sample fixing jig 2. However, it is to be understood that there may be one test sample 3.
Thus, when the motor 13 drives the rotation shaft 11 to rotate, the turntable 14, the sample fixing jig 2 disposed on the turntable 14, and the inspected sample 3 fixed on the sample fixing jig 2 rotate together therewith. Thereby, the sample to be tested can be arranged displaceably in the chamber of the inner housing 1. Thus, when the sample 3 to be tested is moved within the chamber of the inner housing 1, the sample 3 to be tested is relatively moved with respect to the fluid contained in the inner housing 1.
In this description, a mode in which one sample 3 to be detected is fixed to a corresponding one of the sample fixing jigs 2 will be described as an example. As shown in fig. 2, the sample fixing jig 2 is rotatably fixed at its central portion on the turntable 14 by a bolt 2a, for example, on the outer circumference of the turntable 14. The sample fixing jig 2 can be rotated with respect to the outer circumference of the turntable 14 by the bolt 2a and fixed after being rotated by a predetermined angle corresponding to an angle of the to-be-detected sample 3 with respect to a bottom surface 10a (in the present embodiment, the bottom surface 10a is flush with a horizontal plane) described later. Both side ends of the sample fixing jig 2 and both side ends of the sample 3 to be inspected are provided with screw holes which can be aligned with each other, correspondingly.
Further, the spacer 4 is provided for adjusting the angle of the test sample 3 with respect to the bottom surface 10 a. The cushion block 4 is block-shaped. When the pad 4 is placed on the base 10 such that its lower surface is placed parallel to the bottom surface 10a, the upper surface of the pad 4 is inclined to some extent with respect to the bottom surface 10 a. Therefore, when the test specimen 3 is placed on the mat 4 such that one side surface of the test specimen 3 is placed in parallel on the upper surface of the mat 4, the test specimen 3 is inclined with respect to the bottom surface 10a to the same extent as the inclination of the mat 4 with respect to the bottom surface 10 a. In this case, the inclined sample 3 to be tested is fitted into the jig seat 2b of the sample fixing jig 2, and both side ends of the sample 3 to be tested and both side ends of the sample fixing jig 2 have screw holes aligned with each other. In this state, screws 2c (e.g., two in the present embodiment) are inserted into the screw holes from the side of the test specimen 3, thereby fixing the test specimen 3 to the corresponding specimen fixing jig 2.
In addition, in a similar manner to that described above, other samples 3 to be inspected are also fixed to the corresponding sample fixing jigs 2 at different angles with respect to the bottom surface 10a of the inner housing 1, respectively. Specifically, the mat 4 having the upper surface with different degrees of inclination may be fabricated so that the test specimen 3 has different angles of inclination with respect to the bottom surface 10a while being placed on the upper surface of the mat 4, as shown in fig. 1.
Further, the detection device according to the first embodiment of the present invention may include a temperature control device for controlling the temperature of the fluid in the inner case. Specifically, the temperature control device comprises a heater 6, a temperature control box 8 and a heating power supply 9 which are mutually connected to form a temperature control loop. In the present embodiment, the outer case 7 is disposed outside the inner case 1 with a space formed therebetween. The heater 6 is placed in the space and connected to the temperature control box 8 and the heating power supply 9 by wires, thereby heating the fluid inside the inner case 1. The temperature control box 8 can control the heating temperature of the fluid by the heater 6. In this way, the fluid inside the inner housing 1 may have a certain temperature.
The assembling operation of fixing the sample 3 to be tested to the sample fixing jig 2 and the operation of the testing apparatus will be described in detail with reference to the accompanying drawings.
First, the operation of fixing the test sample 3 is described. A plurality of blocks corresponding to the number of the samples 3 to be tested are respectively placed on the base 10 of the inner case 1 so that each block 4 has a different inclination angle with respect to the bottom surface 10a of the base 10. Then, the test samples 3 are placed one by one on the corresponding pads 4 so as to be inclined with respect to the bottom surface 10a by an amount determined by the inclination of the upper surface of the pad 4 with respect to the bottom surface 10 a. Then the sample 3 to be tested is moved close to the corresponding sample fixing jig 2 while being placed on the pad 4 and is fitted into the jig seat 2b of the sample fixing jig 2, and during this process, the sample fixing jig 2 can be rotated relative to the turntable 14 so that the screw holes of both side ends of the sample fixing jig 2 and the screw holes of both side ends of the sample 3 to be tested are aligned. Then, the screws 2c are inserted into the screw holes of the test specimen 3 and the specimen fixing jig 2, thereby fixing the plurality of test specimens 3 to the corresponding specimen fixing jigs 2, respectively. Then, the sample fixing jig 2 is fixed at its central portion to the turntable 14 by the bolts 2 a. Thereby, the sample fixing jig 2 is fixed in the turntable 14 together with the sample 3 to be tested at different angles with respect to the bottom surface 10 a. Thus, the assembling operation of the test sample 3 is completed.
Then, the operation of the detection device is described. A predetermined amount of fluid is contained in the chamber, i.e., the fluid space, of the inner housing 1, the predetermined amount being based on the ability to immerse at least a portion of the fixed sample 3 to be tested. The motor 13 drives the rotary shaft 11 to rotate through the belt 12, so that the rotary disk 14 and the sample fixing jig 2 fixed thereon and the sample 3 to be tested rotate together therewith, during which the sample 3 to be tested can make relative movement with respect to the fluid in the fluid space and at least a part of the sample 3 to be tested is kept in contact with the fluid continuously during the relative movement. At the same time, the heater 6 of the temperature control device can heat the fluid in the fluid space and the heating temperature is controlled.
With the detection apparatus for detecting wear resistance of a sample and the operation thereof configured above, the following technical effects can be achieved.
(1) In this embodiment, different fluids may be introduced into the chamber (fluid space) of the inner housing 1, so as to simulate different working environments of the sample 3 to be tested, for example, real environments where the fluid is water with different sand content, pure water, salt water (e.g. seawater), or organic solution. Therefore, by simulating the influence relationship of these environmental factors on the wear resistance of the material of the test sample 3 to a great extent, and thus by simulating these environments to a great extent, the wear resistance of the material of the test sample 3 under these environments can be detected more accurately and reliably.
(2) In this embodiment, the rotation speed of the rotating shaft 11 can be controlled by the motor 13, so that the influence relationship on the wear resistance of the material of the detected sample 3 in the same fluid at different rotation speeds can be simulated, and the wear resistance of the material of the detected sample 3 at different rotation speeds can be detected more accurately and reliably.
(3) In the present embodiment, a plurality of samples to be detected 3 may be provided in the detection apparatus at the same time. Therefore, the wear resistance of the inspected samples 3 of a plurality of different materials can be inspected at the same time. Therefore, the detection efficiency can be greatly improved.
(4) In the present embodiment, a plurality of samples 3 to be inspected may be simultaneously provided in the inspection apparatus, and each sample 3 to be inspected is fixed to the sample fixing jig 2 at a different angle with respect to the bottom surface 10a of the inner housing 1. Therefore, the influence relation of the wear resistance of the material of the detected sample 3 under different stress angles can be simulated, so that the wear resistance of the material of the detected sample 3 under different angles can be detected more accurately and reliably.
(5) In this embodiment, the detection means may comprise temperature control means for controlling the temperature of the fluid. Therefore, the influence relationship of the wear resistance of the material of the detected sample 3 at different temperatures can be simulated, for example, the wear resistance of the detected sample 3 at different temperatures in the four seasons of spring, summer, autumn and winter can be different, so that the wear resistance of the material of the detected sample 3 at different temperatures can be detected more accurately and reliably.
The first embodiment according to the present invention is substantially as described above. However, the present invention is not limited thereto. It should be understood that various modifications to the above-described arrangements may be suggested to those skilled in the art, which fall within the scope of the appended claims.
For example, in the above-described first embodiment, the sample fixing jig 2 includes the tray-shaped jig base 2b, and the sample 3 to be detected is fixed to the jig base 2b by the screws 2c, but the present invention is not limited thereto, and the sample fixing jig 2 may have other structures. For example, the sample fixing jig 2 may have a common snap ring structure, and the sample 3 to be detected may be fixed in the snap ring structure.
A detection apparatus according to a second embodiment of the present invention is described below with reference to fig. 3. Fig. 3 is a schematic view of a detection apparatus according to a second embodiment of the present invention.
As shown in fig. 3, the inspection apparatus includes a sealed fluid space defined by an inner housing 101 containing a predetermined amount of fluid and a pipe 101c fluidly connecting a fluid inlet 101a and a fluid outlet 101b of the inner housing 101, and a sample fixing jig 102. The inner housing 101 is fluidly connected to the fluid control device 104 via a conduit 101 c. The fluid control device 104 includes a fluid input/output portion 104a for inputting/outputting a fluid, a temperature control device 104b for controlling the temperature of the fluid, a flow rate control device 104c for controlling the flow rate of the fluid, and the like.
A sample holding fixture 102 is located within the fluid space, more specifically, within the inner housing 101. The sample holding jig 102 is immovably fixed in the chamber of the inner housing 101. The inspected sample 103 is fixed to the corresponding sample fixing jig 102 at different angles with respect to the bottom surface 1010a of the inner housing 101.
From this fluid control device 104, the fluid flows into the chamber of the inner housing 101 through the fluid inlet 101a, flows through the chamber of the inner housing 101 to which the sample fixing jig 102 and the sample 103 to be detected are fixed, and flows out of the inner housing 101 through the fluid outlet 101b and again flows into the fluid control device 104. In the fluid control device 104, the temperature and the flow rate of the fluid are controlled by a temperature control device 104b and a flow rate control device 104c, respectively. Thus, when the fluid flows from the fluid inlet 101a to the fluid outlet 101b via the inner housing 101, the sample 103 to be tested is relatively moved with respect to the fluid, and the relative movement is actually caused by the movement of the fluid without moving the sample 103 to be tested.
According to the detecting device of the second embodiment of the present invention, the influence relationship of the plurality of detected samples 103 on the wear performance of the material of the detected sample 103 under different flow rates, different temperatures and different angles can also be simulated, so that the wear performance of the material of the detected sample 103 can be detected more accurately and reliably. In addition, the wear resistance of a plurality of samples 103 to be detected can be detected simultaneously, and therefore, the detection efficiency can be improved.
Although the invention has been described in detail with reference to specific embodiments, it will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the scope of the embodiments described above.
