Description

Technical Field

[0001] The utility model relates to the technical field of control devices, in particular to a temperature control device for a vacuum high-temperature creep testing machine. Background Technique

[0002] Creep refers to the phenomenon that under a certain temperature and a small constant external force, the strain of a material gradually increases with the extension of time. The creep performance of polymers reflects the dimensional stability and long-term load-bearing capacity of materials, and has important practicality. At present, there are many research instruments for the creep of materials such as metals and ceramics, but there are few studies on the development of creep meters for polymer materials, especially polymer membranes. According to the publication number: CN204556377U, a multi-specimen polymer material membrane creep testing machine is disclosed, belonging to the technical field of detection. The laser beam emitted by the laser in the displacement measurement module group is reflected by the plane mirror under the load and then reaches the photodetector. The data acquisition card sends the collected spot position information to the computer for display and processing. When a load is applied, the specimen between the upper fixture and the lower fixture undergoes creep. At this time, the plane mirror under the load undergoes displacement, and the displacement of the plane mirror is recorded by the photodetector to realize the test of the creep deformation amount of the specimen. The device of the utility model has simple operation, and the photodetector makes the measurement more accurate. The temperature control module can keep the temperature of the specimen consistent, and the displacement measurement module group is convenient for simultaneous measurement of multiple groups of specimens. However, the above technology still has some defects. For example, most of the heating devices of the existing creep testing machines are directly fixed in the middle of the fixed rod and cannot be adjusted as needed during use, so the practicability is poor and improvement is needed.

The motor 8 drives the threaded rod 9 to rotate, drives the rotating rod 10 to move up and down, and then accurately adjusts the position of the heating plate 23 to achieve precise control of the temperature of the specimen. The design of the sliding sleeve 14 and the screw rod 18 allows users to flexibly adjust the position of the pressing pad 20 according to experimental requirements, ensuring uniform heating of the specimen and avoiding problems such as local overheating or uneven cooling.

[0025] Support columns 2 are installed at the four corners of the bottom end of the base 1. The threaded rod 9 rotates inside the mounting plate 6 through the rotating groove 7.

The sliding rod 29 installed at the top end of the side plate 28 cooperates with the sliding groove 30 opened on the mounting plate 6, enabling the sliding rod 29 to smoothly slide in the sliding groove 30. This design not only achieves precise positioning and stable movement between components but also facilitates the user to adjust the positions of various components according to experimental requirements, improving the flexibility and applicability of the equipment. The side plates 28 are symmetrically distributed at the left and right ends of the fixing plate 27. The sliding rod 29 slides inside the mounting plate 6 through the sliding groove 30, ensuring the balance and stability of the structure. The sliding rod 29 slides inside the mounting plate 6 through the sliding groove 30. This mechanism allows the sliding rod 29 to smoothly move inside the mounting plate 6, thereby achieving precise positioning and adjustment of the equipment components.

[0028] Working principle: When in use, first place the base 1 at the required position, so that the support column 2 firmly supports the base 1. Then, pinch the pull handle 26 and pull it backward, so that the cover plate 25 rotates backward on the surface of the outer shell 22 through the hinge 24. When the cover plate 25 is completely opened, it is okay. At this time, connect the workpiece between the connecting block A3 and the connecting block B12. After the workpiece is connected, then pinch the pull handle 26 and pull it toward the outer shell 22, so that the cover plate 25 rotates through the hinge 24. When the cover plate 25 is completely closed, it is okay. During the use process, the heating plate 23 can heat the workpiece. And when it is necessary to tighten the workpiece, start the motor 8 at the top of the mounting plate 6, so that the threaded rod 9 rotates inside the mounting plate 6 through the rotating groove 7. And at this time, the rotating rod 10 rotates on the surface of the threaded rod 9 through the threaded groove 11, and drives the connecting block B12 to slide upward through the fixed plate 27. When the workpiece is tightened, it is okay. And when sliding upward, the fixed plate 27 can drive the sliding rod 29 to slide upward through the side plate 28, so that the sliding rod 29 slides upward inside the mounting plate 6 in the middle of the top plate 5 through the sliding groove 30 to play a limiting effect. And when it is necessary to adjust the height of the heating plate 23, pinch the turning handle 19 and rotate it, so that the screw rod 18 rotates inside the fixed block 16 through the rotating groove 17. When the pressure pad 20 is away from the fixed plane 13, it is okay. Then, pinch the sliding sleeve 14 and push and pull it, so that the sliding sleeve 14 slides on the surface of the fixed rod 4 through the sliding groove 15. When the sliding sleeve 14 slides to the required position, it is okay. Then, tighten the turning handle 19. And at this time, the screw rod 18 rotates on the side of the pressure pad 20. When the pressure pad 20 tightly fits on the surface of the fixed rod 4 through the fixed plane 13, the sliding sleeve 14 can be firmly fixed. And at this time, the sliding sleeve 14 firmly supports the outer shell 22 through the connecting rod 21.
