Description

Technical Field

[0001] This utility model belongs to the field of synchronization ring detection, and in particular relates to a bidirectional detection device for synchronization ring coordination height. Background Technology

[0002] The synchronizing ring is a crucial component of a synchronizer. Its design purpose is to synchronize the rotational speeds of the input and output shafts during gear shifting, thereby achieving smooth, shock-free gear changes. Synchronizing rings are typically made of wear-resistant, high-strength materials and consist of three parts: an outer ring, a middle ring (if applicable), and an inner ring. After the synchronizer is assembled, the height difference between the end faces of the outer ring and the inner ring, as well as the height difference between the middle ring and the inner ring, needs to be checked to ensure proper functioning.

[0003] In existing technologies, most methods use vernier calipers to measure the height difference between the outer and inner ring end faces, as well as the height difference between the middle and inner ring end faces, in a synchronizer. However, because the end faces of the outer, middle, and inner rings are not on the same axis, these two height differences cannot be accurately measured using vernier calipers, resulting in significant errors. In particular, measurements are only taken after the three rings of the synchronizer are tightly assembled; direct measurement with them stacked together also introduces noticeable errors. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a bidirectional detection device for the height of a synchronous ring, which aims to solve the problem of large detection errors in existing bidirectional detection devices for the height of a synchronous ring.

[0005] The present invention adopts the following technical solution:

[0006] The synchronous ring engagement height bidirectional detection device includes a machine base, on which a slide is provided. A fixed plate and a floating plate are mounted on the slide, wherein the floating plate is slidably installed. A compression spring is provided between the fixed plate and the floating plate. A fixed opening is provided on the floating plate, and an outer ring base is provided on the fixed opening. A middle opening is provided on the outer ring base. An inner ring support shaft is provided on the machine base facing the middle opening. An inner ring base is provided on the outer periphery of the inner ring support shaft. A middle ring base and a middle ring floating spring are respectively fitted on the upper and lower parts of the inner ring base. The middle ring floating spring supports the middle ring base. The inner ring base and the middle ring base are both located within the middle opening. A detection ring is provided on the outer periphery of the middle ring base. A pair of displacement sensors are provided on the fixed plate facing upwards. The sensing ends of the displacement sensors are respectively set towards the outer ring base and the detection ring. A pressing mechanism is provided on the machine base facing the floating plate.

[0007] Furthermore, the fixing plate has a groove corresponding to the inner ring support shaft, the bottom of the inner ring base is fixedly installed in the groove, and the middle ring floating spring is located in the groove.

[0008] Furthermore, the pressing mechanism includes a stand, and a downward cylinder is provided on the stand facing downward. The drive shaft of the downward cylinder is provided with a pressure plate for pressing down the outer ring, and a ring of pressure blocks is provided on the pressure plate.

[0009] Furthermore, the slide includes four slide rods, with the fixed plate fixed in the middle of the slide rods and the floating plate installed at the top through a limiting sleeve. Each slide rod is provided with a compression spring between the fixed plate and the floating plate.

[0010] Furthermore, the top of the central ring base has several limiting slots facing downwards.

[0011] The beneficial effects of this invention are as follows: When the outer ring, middle ring, and inner ring are fitted together, the height difference between the outer ring and the end face of the inner ring is equal to the value collected by the left displacement sensor plus the thickness of the outer ring base minus the height of the inner ring base. Similarly, the height difference between the middle ring and the end face of the inner ring is equal to the value collected by the right displacement sensor plus the height of the upper part of the detection ring minus the height of the inner ring base. Therefore, after the above calculations, the height difference between the outer ring and the end face of the inner ring, and the height difference between the middle ring and the end face of the inner ring, are displayed on the screen. Thus, it can be seen that when using this device to detect the synchronization ring fitting height, the above two height differences can be measured at once. The entire measurement process is relatively simple, time-saving, labor-saving, and has high measurement accuracy. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0019] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0020] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0021] Combination Figure 2-5 As shown, the synchronous ring engagement height bidirectional detection device includes a machine base 1, on which a slide is provided. A fixed plate 32 and a floating plate 31 are installed on the slide. The floating plate 31 is slidably installed. A compression spring 22 is provided between the fixed plate 32 and the floating plate 31. The floating plate 31 has a fixing opening. An outer ring base 5 is provided on the fixing opening. A middle opening is provided on the outer ring base 5. An inner ring support shaft 6 is provided on the machine base 1 facing the middle opening. An inner ring base 7 is provided on the outer periphery of the inner ring support shaft 6. A middle ring base 8 and a middle ring floating spring 81 are respectively fitted on the upper and lower parts of the inner ring base 7. The middle ring floating spring 81 supports the middle ring base 8. The inner ring base 7 and the middle ring base 8 are both located inside the middle opening. A detection ring 92 is provided on the outer periphery of the middle ring base 8. A pair of displacement sensors 10 are provided on the upper side of the fixed plate 32. The sensing ends of the displacement sensors 10 are respectively set towards the outer ring base 5 and the detection ring 92. A pressing mechanism is provided on the machine base 1 facing the floating plate 31.

[0022] The synchronizing ring is a crucial component of a synchronizer. Its design purpose is to synchronize the rotational speeds of the input and output shafts during gear shifting, thereby achieving smooth, shock-free gear changes. Synchronizing rings are typically made of wear-resistant, high-strength materials and consist of three parts: an outer ring, a middle ring, and an inner ring. After the synchronizer is assembled, the height difference between the end faces of the outer ring and the inner ring, as well as the height difference between the middle ring and the inner ring, needs to be checked to ensure proper functioning.

[0023] In this structure, the outer ring base 5, the middle ring base 8, and the inner ring base 7 are used to support and limit the outer ring 11, the middle ring 12, and the inner ring 13, respectively. When using this device to measure the mating height of the synchronization ring, the outer ring, the middle ring, and the inner ring need to be assembled on the outer ring base, the middle ring base, and the inner ring base as required. Specifically: First, place the bottom end face of the inner ring on the inner ring base, and position it using the stop of the inner ring base. Then, place the bottom end face of the middle ring on the outer conical surface of the inner ring, at which point the middle ring base is lifted by the floating spring of the middle ring, and there is a distance of about 2mm between it and the measuring surface (i.e., the bottom end face of the inner ring). Finally, place the bottom end face of the outer ring on the outer ring base, with a distance of about 4mm between the bottom end face of the outer ring and the measuring surface. At this point, the assembly and testing are completed. Then, the pressing mechanism can be used to press down the lower end face of the outer ring to detect the height difference between the two points mentioned above.

[0024] like Figure 2-3The pressing mechanism includes a stand 14, a downward cylinder 15 is provided on the stand 14 facing downward, and a pressure plate 16 for pressing down the outer ring is provided on the drive shaft of the downward cylinder 15. A ring of pressure blocks 17 is provided on the pressure plate 16.

[0025] When the pressing mechanism is used to press down the skirt of the outer ring, the operator first activates the button, and the downward cylinder starts working. The drive shaft of the downward cylinder drives the pressure plate to move downward. At this time, the pressure block at the bottom of the pressure plate contacts the skirt of the outer ring and pushes the outer ring downward a short distance. Simultaneously, the inner conical surface of the outer ring contacts the outer conical surface of the middle ring, pushing the middle ring downward a short distance, and the floating spring of the middle ring is compressed. In this embodiment, the set pressure of the downward cylinder is 150N. When the force is reached, the outer ring, middle ring and inner ring are tightly fitted together, and the downward cylinder stops working. The two displacement sensors collect data.

[0026] Since both displacement sensors are mounted on a fixed plate, in the diagram, the sensing end of the left displacement sensor faces the outer ring base 5, and the sensing end of the right displacement sensor faces the detection ring 92. The left and right displacement sensors are used to measure the distance from their sensing ends to the outer ring base and the detection ring, respectively. Because the inner ring base is fixedly mounted on the inner ring support shaft, the position of the inner ring base remains unchanged during the downward pressing process of the downward cylinder.

[0027] Therefore, when the outer ring, middle ring, and inner ring are tightly fitted together, the height difference between the outer ring and the inner ring end face is equal to the value collected by the left displacement sensor plus the thickness of the outer ring base minus the height of the inner ring base (a constant). The height difference between the middle ring and the inner ring end face is equal to the value collected by the right displacement sensor plus the height of the upper part of the detection ring minus the height of the inner ring base. Therefore, after the above series of calculations, the height differences between the outer ring and the inner ring end face, and the height differences between the middle ring and the inner ring end face, are displayed on the screen. It can be seen that when using this device to detect the synchronization ring fitting height, the above two height differences can be measured at once. The entire measurement process is relatively simple, time-saving, labor-saving, and has high measurement accuracy.

[0028] As a preferred structure, such as Figure 4 The fixing plate 32 has a groove 18 corresponding to the inner ring support shaft 6. The bottom of the inner ring base 7 is fixedly installed in the groove 18, and the middle ring floating spring 81 is located in the groove 18. In this structure, the inner ring base is installed in the groove, the middle ring floating spring is sleeved on the inner ring base, and the middle ring floating spring is located in the groove. The groove is mainly used for limiting and installing the middle ring floating spring.

[0029] As a specific structure, such as Figure 2-3The slide includes four slide rods 21. The fixed plate 32 is fixed in the middle of the slide rod 21, and the floating plate 31 is installed at the top through a limiting sleeve. A compression spring 22 is provided on each slide rod 21 between the fixed plate 32 and the floating plate 31.

[0030] In addition, such as Figure 6 The top of the central ring base 8 has several limiting slots 19 facing downwards. For example... Figure 1 In this design, a ring of toothed blocks 121 is formed on the bottom surface of the middle ring 12, and the number of limiting slots is the same as the number of toothed blocks. The middle ring is then placed on the middle ring base, with the toothed blocks aligned with the limiting slots. Next, the large end face of the middle ring is placed on the outer conical surface of the inner ring, at which point the toothed blocks are located within the limiting slots. The limiting slots serve to avoid the toothed blocks while simultaneously limiting the movement of the middle ring.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
