Technical Field

[0002] The Stirling cryostat (hereinafter referred to as the cryostat), as an important component of infrared detectors, primarily functions to provide a stable ultra-low temperature operating environment for the detector's normal operation, thereby improving its performance. The cylinder and piston play a central role in the cryostat, and their condition directly affects the cryostat's efficiency and performance. The cylinder in the cryostat includes a compression cylinder and an expansion cylinder. The cylinder has a smooth inner wall to house the piston, which reciprocates within it and withstands gas pressure. The mating clearance between the cylinder and piston is at the micrometer level, therefore the design and manufacturing of the cylinder requires precise dimensions and a smooth inner wall to reduce friction and ensure the cryostat's efficiency and performance.

The efficiency and accuracy of this observation directly affect the operator's machining efficiency and quality. Currently, operators typically hold the cylinder block by hand and observe the inner wall of the cylinder under a 15x magnifying glass to confirm whether the machined cylinder block meets the requirements. However, hand-holding the cylinder block for observation cannot ensure its stability; the cylinder block is prone to shaking and wobbling, affecting the observation results and efficiency.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0030] In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms “center”, “longitudinal”, “transverse”, “length”, “width”, “thickness”, “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom”, “inner”, “outer”, “clockwise”, “counterclockwise” and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0031] In one aspect, asFigures 1 to 3 As shown, an embodiment of the present application provides a detection auxiliary tool 100, which comprises a bracket 110, a lifting block 121, a mounting block 131, a mounting shaft 140 and a bearing 150.

[0032] The lifting block 121 is arranged on the bracket 110 and can be adjusted in position along the vertical direction; the mounting block 131 is rotatably connected to the lifting block 121 around a first axis in the horizontal direction, the mounting shaft 140 is rotatably connected to the mounting block 131 around a second axis perpendicular to the first axis, and the second axis coincides with the central axis of the mounting shaft 140, that is, the mounting shaft 140 can rotate on the mounting block 131. The bearing 150 is detachably connected to one end of the mounting shaft 140, and the bearing 150 is used to bear the detection object.

[0033] It should be noted that in the embodiment, the detection object is a cylinder body 200. In other embodiments, the detection object can also be other products, which are not limited here. Hereinafter, the cylinder body 200 is taken as an example for description.

[0034] With the above detection auxiliary tool 100, the detection device is located above the tool, the cylinder body 200 is placed on the bearing 150, the mounting block 131 is first rotated to adjust the observation angle of the cylinder body 200, the position of the lifting block 121 is adjusted along the vertical direction after the observation angle is determined, to ensure that the inner wall of the cylinder body 200 is located at the focal point of the detection device, and to ensure the clarity of observation. Next, the mounting shaft 140 can be rotated to drive the cylinder body 200 to rotate, to realize comprehensive inspection of the inner wall of the cylinder body 200. Since the tool is placed on the table, and the cylinder body 200 is placed on the tool, it is more stable and will not shake and wobble, effectively improving the observation effect and efficiency.

[0035] In addition, the bearing 150 is detachably connected to one end of the mounting shaft 140, and the bearing 150 is used to bear the cylinder body 200. If different specifications of the cylinder body 200 need to use different bearings 150, the bearing 150 can be directly replaced at this time, improving the applicability of the detection auxiliary tool 100 and reducing the detection cost. For example, Figure 1 The bearing 150 in the idle state as shown is suitable for different specifications of the cylinder body 200.

[0036] It should be explained that during the observation of the inner wall of the cylinder body 200, the observation angle is usually changed to ensure the accuracy of observation. In the embodiment, the observation angle of the cylinder body 200 is realized by rotating the mounting block 131, and after the mounting block 131 is rotated, the height of the cylinder body 200 will change. Therefore, after the observation angle is adjusted, the lifting block 121 needs to be moved along the vertical direction to ensure that the inner wall of the cylinder body 200 is located at the focal point of the detection device.

[0037] In one embodiment, the detection auxiliary tool 100 further comprises a base 160, and the bracket 110 is arranged on the base 160. The supporting surface of the base 160 is larger than that of the bracket 110, which can ensure that the tool is stably placed on the table top.

[0038] In one embodiment, the number of the bracket 110 and the lifting block 121 is two, the two brackets 110 are arranged at intervals on the base 160, and the two lifting blocks 121 are arranged on the two brackets 110, respectively. The two ends of the mounting block 131 are rotatably connected with the two lifting blocks 121, so that the mounting block 131 can move more stably in the vertical direction. It can be understood that the first axis extends along the arrangement direction of the two brackets 110.

[0039] In one embodiment, the detection auxiliary tool 100 further comprises an adjusting member 122, which is connected with the bracket 110 and the lifting block 121 to adjust the position of the lifting block 121 in the vertical direction. Further, the adjusting member 122 is threadedly connected with the bracket 110 and rotatably connected with the lifting block 121, so as to drive the lifting block 121 to move in the vertical direction during rotation. Alternatively, the adjusting member 122 is a screw.

[0040] It can be understood that the bracket 110 is provided with a structure for limiting the rotation or horizontal movement of the lifting block 121, for example Figure 1 In this embodiment, the number of the adjusting member 122 is one, and the adjusting member 122 is connected with one of the brackets 110 and the corresponding lifting block 121. The other lifting block 121 moves synchronously under the action of the mounting block 131. Moreover, the other lifting block 121 can be manually assisted to rise and fall during vertical movement, so as to avoid being stuck.

[0041] In one embodiment, the detection auxiliary tool 100 further comprises a rotating shaft 132, which is rotatably connected with the lifting block 121 around the first axis, and the mounting block 131 is fixedly connected with the rotating shaft 132. As known from the above embodiment, the two ends of the mounting block 131 are connected with two rotating shafts 132, respectively, and the two rotating shafts 132 are rotatably connected with the two lifting blocks 121 through bearings. In other embodiments, the mounting block 131 can be formed with two columnar protrusions, and the two columnar protrusions are rotatably connected with the two lifting blocks 121 through two bearings.

[0042] In one embodiment, the detection auxiliary tool 100 further comprises a locking member 133 connected to the mounting block 131 and capable of abutting against the support 110, the locking member 133 being capable of locking and releasing the mounting block 131. When the locking member 133 locks the mounting block 131, the mounting block 131 is fixed relative to the support 110; when the locking member 133 releases the mounting block 131, the mounting block 131 is capable of rotating about the first axis. In this way, after the observation angle adjustment is completed, the mounting block 131 is locked by the locking member 133, so that the observation angle is fixed; when the observation angle needs to be adjusted, the mounting block 131 is released by the locking member 133, and then the mounting block 131 is rotated.

[0043] In actual application, the locking member 133 is threadedly connected with the rotating shaft 132, and the locking member 133 is capable of abutting against the support 110 during rotation, so as to lock and fix the rotating shaft 132. It can be understood that during the process of tightening the locking member 133, the locking member 133 will abut against the support 110, and a pressure parallel to the first axis will be generated between the locking member 133 and the support 110, corresponding to the pressure parallel to the first axis existing between the locking member 133 and the rotating shaft 132. When the pressure is large, the friction between the locking member 133 and the support 110 and the rotating shaft 132 will reach the effect of fixing the rotating shaft 132. Of course, in other embodiments, a damping structure can also be arranged between the mounting block 131 or the rotating shaft 132 and the lifting block 121 or the support 110, for providing damping for the rotation of the mounting block 131; at this time, the rotation of the mounting block 131 needs to exert a certain external force, but the mounting block 131 will not rotate again after the external force is removed.

[0044] In one embodiment, the detection auxiliary tool 100 further comprises a magnetic member 171 arranged at one end of the bearing member 150 or the mounting shaft 140, so as to enable the bearing member 150 to be adsorbed and fixed at one end of the mounting shaft 140. In actual application, the bearing member 150 is provided with a clamping portion 151 clamped by the cylinder body 200, and the end of the bearing member 150 away from the clamping portion 151 is used for adsorbing and fixing at one end of the mounting shaft 140.

[0045] For the specific arrangement form of the magnetic member 171, the following three examples can be referred to:

[0046] Example 1: The magnetic member 171 is arranged at one end of the mounting shaft 140; the detection auxiliary tool 100 further comprises a cooperating member 172 arranged on the bearing member 150, and the magnetic member 171 is capable of adsorbing the cooperating member 172, so as to adsorb and fix the bearing member 150. In this example, the bearing member 150 is preferably made of plastic material, so as to avoid scratching the cylinder body 200; the cooperating member 172 can be iron or a magnet, and is not limited herein.

[0047] In Example 2, the magnetic attraction member 171 is arranged at one end of the mounting shaft 140, and the magnetic attraction member 171 can attract and fix the bearing member 150; the clamping portion 151 of the bearing member 150 is covered with a flexible pad. In this example, the bearing member 150 is made of iron, and in order to avoid scratching the cylinder body 200, the flexible pad is arranged on the surface of the clamping portion 151.

[0048] In Example 3, the magnetic attraction member 171 is arranged at one end of the bearing member 150 away from the clamping portion 151, and the mounting shaft 140 is made of iron, so that the bearing member 150 is attracted and fixed to one end of the mounting shaft 140 by the magnetic attraction member 171.

[0049] In one embodiment, the bearing member 150 is further provided with a docking portion 152 at one end away from the clamping portion 151; one end of the mounting shaft 140 is provided with a limiting groove 141, and the docking portion 152 can be inserted into the limiting groove 141 to realize the connection between the bearing member 150 and the mounting shaft 140 and to limit the bearing member 150. Taking Example 1 as an example, the cooperating member 172 is arranged on the docking portion 152, and the magnetic attraction member 171 is arranged inside the mounting shaft 140 and below the limiting groove 141, so as to attract and fix the docking portion 152 after it is inserted into the limiting groove 141.

[0050] On the other hand, the application also provides a detection device, which comprises a workbench, a detection device and the detection auxiliary tool 100 in the above embodiments, the detection device and the detection auxiliary tool 100 are arranged on the workbench, and during the detection process, the detection device is located above the detection auxiliary tool 100.

[0051] In order to facilitate the understanding of the technical scheme of the application, the technical scheme of the application will be described in detail below with reference to the accompanying drawings. Figure 3 The detection process of the detection device will be described:

[0052] First, insert the cylinder body 200 into the corresponding bearing member 150, and then attract and fix the docking portion 152 of the bearing member 150 in the limiting groove 141 of the mounting shaft 140. Next, determine the observation angle, and rotate the mounting shaft 140 (mounting block 131) counterclockwise or clockwise according to the observation angle, and after the observation angle is adjusted, tighten the locking member 133 to fix the mounting block 131. Then, adjust the height of the cylinder body 200 by rotating the adjusting member 122 according to the picture observed by the detection device, until the picture observed is clear. Finally, rotate the mounting shaft 140 to realize comprehensive observation and detection of the inner wall of the cylinder body 200. When the observation angle needs to be changed later, loosen the locking member 133, and then repeat the above steps.
