Description

Technical Field

[0001] The present invention relates to the technical field of rolling element testing, and particularly to a corrosion resistance testing device for rolling elements of a composite material machine tool spindle. Background Art

[0002] With the rapid development of modern manufacturing industry, as the core component of a machine tool, the performance of the machine tool spindle directly affects the machining accuracy, efficiency and stability. However, the machine tool spindles made of traditional metal materials have many limitations under high-speed, high-precision and complex working conditions, such as large weight, high coefficient of thermal expansion, limited fatigue resistance, etc. In recent years, the application of composite materials in the field of mechanical manufacturing has gradually attracted attention. By combining the characteristics of different materials, composite materials can significantly improve the performance of components. In these applications, composite materials are often exposed to extreme environments, such as high temperature and pressure and corrosive media. Especially in highly corrosive environments, the corrosion resistance of composite materials is particularly important. Therefore, evaluating and testing the corrosion resistance of rolling elements of a machine tool spindle is crucial for ensuring reliability and safety.

[0003] In the past, when testing the corrosion resistance of rolling elements of a machine tool spindle, they were generally placed on a sample rack, and a chemical agent spray head located above the sample rack was used to spray corrosion chemicals on the rolling elements. However, when the chemicals are sprayed from top to bottom, there will be a testing blind area in the area of the rolling elements of the machine tool spindle facing away from the chemical agent spray head, and the amount of chemicals contacted by the entire rolling elements of the machine tool spindle varies greatly, resulting in inaccurate testing results of the corrosion resistance of the samples. The existing solution is to manually turn the rolling elements regularly. When turning, the rolling elements are likely to fall off the sample rack, and secondly, the problem that the chemical agent reception amount at each position of the rolling elements cannot be well solved still cannot be solved.

[0004] Based on this, the inventor designed a corrosion resistance testing device for rolling elements of a composite material machine tool spindle to solve the above problems, and thus, this application is proposed. Summary of the Invention

[0005] The purpose of this application is to provide a corrosion resistance testing device for rolling elements of a composite material machine tool spindle, which solves the problem that the corrosion resistance test effect of the rolling elements in the prior art is not good due to the large difference in the amount of chemical agent contacted at each position.

[0041] The present invention will be described in detail below by referring to the drawings and in conjunction with embodiments.

[0042] Embodiment 1:

[0043] As Figure 1 and Figure 2 shown, the present application provides a corrosion - resistance test device for rolling elements of a composite - material machine - tool spindle, including a hanging rack 2 and a material - supporting net 3, and a driving mechanism 7 for driving the material - supporting net 3 to reciprocate along the length direction of the hanging rack 2, wherein:

[0044] A number of rope - passing structures are provided on the hanging rack 2 along its length direction;

[0045] The material supporting net 3 includes a plurality of net pocket segments 32 located below the hanging rack 2, and a plurality of stay cord segments 31 arranged at intervals with the net pocket segments 32. The main part of the stay cord segments 31 is located above the hanging rack 2, and both ends or one end of the stay cord segments 31 pass through the cord threading structure and are fixedly connected to the net pocket segments 32;

[0046] The stay cord segments 31 at both ends of the material supporting net 3 are in transmission connection with the output end of the driving mechanism 7.

[0047] In this embodiment, by providing the hanging rack 2, the material supporting net 3, and the driving mechanism 7, the driving mechanism 7 can drive the net pocket end of the material supporting net 3 to move back and forth along the length direction of the hanging rack 2. After the rolling parts 5 to be tested are placed on the net pocket segments 32, as the driving mechanism 7 drives the net pocket segments 32 to reciprocate, the rolling parts 5 to be tested can reciprocally roll within the net pocket segments 32, thereby ensuring that all positions thereof can fully and evenly receive the corrosion agent, and effectively solving the problem in the prior art that due to the large difference in the amount of agent contact at each position of the rolling parts, the corrosion resistance test effect is not good.

[0048] The core concept of this embodiment is to drive the net pocket segments 32 of the material supporting net 3 to reciprocate, and in combination with the rod-shaped shape characteristics of the rolling parts 5 to be tested, the rolling parts 5 to be tested placed on the net pocket segments 32 continuously reciprocally roll as the net pocket segments 32 reciprocate, forming the technical effect of performing the corrosion resistance test with the rolling parts 5 to be tested in a dynamic rolling state. Furthermore, it is ensured that not only all positions of the rolling parts 5 to be tested can receive the corrosion of the agent, but also the amount of agent received at each regional position of the rolling parts 5 to be tested is not much different. In addition, the rolling rolling parts 5 to be tested will also cause the atomized agent sprayed on the rolling parts 5 to be tested not to continuously condense and accumulate on the surface of the rolling parts 5 to be tested like the static rolling parts 5 to be tested receiving the sprayed atomized agent, and the continuously accumulated liquid medicine will gradually approach and stay in the area of the rolling part with side plates facing away from the agent nozzle 62 due to gravity, resulting in large differences in the corrosion time, agent concentration, and amount of agent at each position of the rolling parts 5 to be tested, and the corrosion resistance test result is not effective and accurate enough.

[0049] Specifically, in this embodiment, as Figure 2 shown, the hanging rack 2 includes a plurality of hanging rods 21 arranged in parallel on the same horizontal plane along the width direction of the hanging rack 2, and a plurality of the cord threading structures are distributed on the plurality of hanging rods 21 in a rectangular array;

[0050] A plurality of stay cord segments 31 are fixed at both ends of the net pocket segments 32. By providing a plurality of hanging rods 21 and fixing a plurality of stay cord segments 31 at both ends of the net pocket segments 32, the force balance of the net pocket segments 32 can be improved, and it is avoided that the rolling parts 5 to be tested roll out of the net pocket segments 32 during the repeated rolling process.

[0051] In this embodiment, the net bag section 32 is rectangular in shape as a whole and has a certain degree of flexibility. A number of net openings are arranged inside it, and the size of the net openings can be set according to needs, as long as it is verified that the rolling element 5 to be tested cannot pass through the net openings of the net bag section 32 and fall out of the net bag section 32.

[0052] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the mounting frame 2 is also provided with a plurality of pulleys 22 for reducing the friction resistance of the pull rope segment 31;

[0053] The pulleys 22 are all arranged below the main part of the pull rope section 31;

[0054] The rope threading structure is a rope threading hole 211 arranged on the hanging rod 21. The pulley 22 in this embodiment can effectively reduce the friction resistance of the pull rope segment 31, so that the driving mechanism 7 only needs lower power to drive the supporting net 3 to move back and forth; the rope threading structure in this embodiment can also be replaced with a circular hanging ear, and the pull rope segment 31 of the supporting net 3 can be passed through the hanging ear to achieve the same effect as the rope threading hole 211.

[0055] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, it also includes a synchronization mechanism, which includes a first synchronization component 41 and a second synchronization component 42 arranged on both sides of the supporting net 3;

[0056] The output end of the driving mechanism 7 is connected to the supporting net 3 through the first synchronous component 41 and the second synchronous component 42 of the synchronous mechanism. By setting the first synchronous component 41 and the second synchronous component 42, when the supporting net 3 moves back and forth, the pull rope segments 31 at both ends of the supporting net 3 can move synchronously.

[0057] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the first synchronization component 41 and the second synchronization component 42 have the same structure;

[0058] The first synchronous assembly 41 includes a first rotating shaft 411 and a plurality of first rope reels 412 arranged along the width direction of the hanging frame 2, and the second synchronous assembly 42 includes a second rotating shaft 421 and a plurality of second rope reels 422 arranged parallel to the first rotating shaft 411, and the pull rope segments 31 at both ends of the supporting net 3 are respectively connected to the first rope reel 412 and the second rope reel 422;

[0059] The first synchronous assembly 41 and the second synchronous assembly 42 further include a first synchronous wheel 413 and a second synchronous wheel 423 respectively fixed on the first rotating shaft 411 and the second rotating shaft 421;

[0060] The synchronization mechanism further includes a synchronization belt 43 disposed on the first synchronization wheel 413 and the second synchronization wheel 423 .

[0061] In this embodiment, through the synchronous belt 43 of the synchronization mechanism, the first rotating shaft 411 and the second rotating shaft 421 can be rotated clockwise or counterclockwise at the same time, and the first rotating shaft 411 and the second rotating shaft 421 are respectively provided with a first rope winding wheel 412 and a second rope winding wheel 422, so that when the first rotating shaft 411 and the second rotating shaft 421 rotate synchronously, the pull rope segments 31 at both ends of the material support net 3 can be released on one side and tightened on the other side, so as to avoid the situation where the material support net 3 as a whole is stretched straight after being driven by the driving mechanism 7.

[0062] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the driving mechanism 7 includes a driving motor 71, a driving wheel 73, a driven wheel 74 and a transmission belt 72;

[0063] The driving wheel 73 is mounted on the output shaft of the driving motor 71 , the driven wheel 74 is mounted on the first rotating shaft 411 or the second rotating shaft 421 , and the transmission belt 72 is arranged on the driving wheel 73 and the driven wheel 74 .

[0064] The driving mechanism 7 in this embodiment is a common mechanism in the prior art and will not be described in detail here.

[0065] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, it also includes a test box 1 with a cavity inside;

[0066] The hanging rack 2 and the supporting net 3 are both arranged in the test box 1 , the driving mechanism 7 is arranged outside the test box 1 , and the pull rope segments 31 at both ends of the supporting net 3 pass through the test box 1 and are transmission-connected with the driving mechanism 7 .

[0067] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, it also includes a reagent spraying mechanism 6 disposed in the test box 1;

[0068] The medicine spraying mechanism 6 includes a medicine inlet pipe 61 arranged above the hanging rack 2, and a plurality of medicine spray heads 62 connected to the medicine inlet pipe 61. The medicine spraying mechanism 6 in this embodiment is a common mechanism in the prior art and will not be described in detail here.

[0069] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the number of the medicine spray heads 62 is the same as the number of the net bag ends of the support net 3, and the medicine spray heads 62 are arranged just above the center of the net bag end;

[0070] The spraying area of ​​the chemical spray head 62 is conical, and the end of the net bag is completely located in the conical spraying area of ​​the chemical spray head 62. By arranging a chemical spray head 62 above each net bag segment 32 and making the net bag segment 32 completely located in the conical spraying area of ​​the chemical spray head 62, it can be ensured to the greatest extent possible that the amount of chemical received by the rolling parts 5 to be tested in each net bag segment 32 remains consistent, thereby improving the accuracy of the corrosion resistance test results.

[0071] Specifically, in the present embodiment, the support net 3 is made of corrosion-resistant nylon rope. The technicians can also replace the material of the support net 3 with carbon fiber rope or other materials as needed, which will not be elaborated here.

[0072] Embodiment 2:

[0073] like Figure 3 As shown, in this embodiment, an inverted roller is further provided at the bottom of the hanging rod 21, and the inverted supporting rollers 23 are located on both sides of the net bag section 32 and are arranged close to the rope threading structure.

[0074] In this embodiment, by setting the supporting roller 23, the supporting net 3 will not get stuck at the bottom of the hanging rod 21 during the reciprocating movement of the material supporting net 3 after being pulled, causing the rolling member 5 to be squeezed at the bottom of the hanging rod 21. Instead, sufficient rolling space is always reserved for the rolling member 5 to be tested, so as to facilitate its left and right rolling, thereby ensuring the corrosion resistance test effect of the entire device on the rolling member 5 to be tested.

[0075] The rest of the structure of this embodiment is the same as that of the above-mentioned embodiment 1 and will not be described again here.

[0076] It is to be understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, but the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
