Description

Technical Field

[0001] The utility model relates to the technical field of limit rings, in particular to a detection pin limit ring. Background Art

[0002] One of the functions of the detection pin is to detect the hole depth. The existing detection pin generally has a limit ring on its detection rod, which is used to be stuck on the top surface of the detection hole to limit the detection rod. Then, by observing the scale line on the lower part of the detection rod passing through the detection hole, it is judged whether the hole depth of the detection hole is qualified. However, the limit ring on the detection pin is generally fixedly connected to the detection rod as an integral whole and cannot be disassembled. When detecting the hole depth of detection holes of different depths, it is necessary to purchase and replace detection pins of different lengths, resulting in a high cost of use. In addition, when the distance between the bottom surface of the detection hole on some parts and other parts on the parts is small and is not sufficient to provide the conditions for observing the scale line, it is necessary to customize or purchase detection pins that meet the needs separately, which increases the detection cost.

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings.

[0026] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] The detection pin is generally provided with a limit ring, which is used to clamp on the top surface of the detection hole. Then, the detection rod is passed through the detection hole and the scale line is observed to determine whether the hole depth of the detection hole meets the requirements; Figure 1 When the distance L between the bottom surface of the detection hole 5 and other parts of the part 4 is too small, the position of the limit ring on the general detection pin cannot be adjusted because the limit ring is fixed and integrated with the detection rod 6. The limit ring is located above the detection hole 5, so it is impossible to judge whether the hole depth of the detection hole meets the requirements; in addition, the hole depths of the holes to be detected are inconsistent, and detection pins of different specifications and models need to be purchased, which increases the detection cost; therefore, the present application proposes a detection pin limit ring to realize the detachable function of the limit ring, and the limit ring can be fixed at any position on the limit rod to meet different detection requirements and reduce the detection cost.

[0028] Please refer to Figures 2 to 4 An embodiment of the utility model provides a detection pin limit ring, including an annular main body 1, one side of the inner ring surface of the annular main body 1 is provided with a fixing component 2 corresponding to the detection rod 6 for abutting the wall surface of the detection rod 6, and the other side is provided with a locking component 3 for cooperating with the fixing component 2, for fixing and locking the limit ring on the detection rod 6.

[0029] The ring-shaped body 1 is fixed at any position on the detection rod 6 by the cooperation between the fixing component 2 and the locking component 3, so as to meet the detection requirements of different detection holes 5 and reduce the cost of detection and procurement;

[0030] In a preferred embodiment, the fixing assembly 2 includes an arc plate 21, which is fixedly connected to the inner ring surface of the annular body 1 via a mounting block 22, and the arc plate 21 is used to abut against the wall surface of one side of the detection rod 6.

[0031] In a preferred embodiment, the locking assembly 3 includes an arc plate 2 31, a mounting sleeve 32 and a driving assembly, and the driving assembly is connected to the arc plate 2 31 via a connecting assembly; wherein,

[0032] The mounting sleeve 32 has a threaded front half on its inner wall surface for connection with the drive assembly;

[0033] The driving assembly includes a screw rod 33 threadedly sleeved inside the mounting sleeve 31, and a rotating hand wheel 34 is fixedly provided at one end of the screw rod 33 outside the mounting sleeve 32 for facilitating the rotation of the screw rod 33 inside the mounting sleeve 32;

[0034] The connecting assembly includes a shaft 35 slidably disposed inside the mounting sleeve 32, a bearing 36 is fixedly disposed on one end surface of the shaft 35 close to the screw 33, and the screw 33 is fixedly connected to the inner ring transmission surface of the bearing 36;

[0035] The shaft 35 is provided with a track along its length direction, and a roller is provided on the inner wall surface of the mounting sleeve 32 corresponding to the track, and the roller is embedded in the inner setting of the corresponding track;

[0036] The arc-shaped plate 2 31 is fixedly connected to an end of the shaft rod 35 away from the screw rod 35 .

[0037] In a preferred embodiment, the screw rod 33 , the mounting sleeve 32 , the bearing 36 and the shaft rod 35 are all coaxially arranged.

[0038] In a preferred embodiment, the height of the arc plate 1 21 and the arc plate 2 31 is greater than the height of the annular body 1 .

[0039] Among them, since the height of the arc plate 1 21 and the arc plate 2 31 is greater than the height setting of the annular body 1, that is, the top surface of the arc plate 1 21 and the arc plate 2 31 is higher than the top surface setting of the annular body 1, and the bottom surface of the arc plate 1 21 and the arc plate 2 31 is lower than the bottom surface setting of the annular body 1, it is convenient to adjust and position the position of the annular body 1 so that the distance between it and the scale line on the lower part of the detection rod 6 meets the requirements.

[0040] In a preferred embodiment, a layer of anti-skid rubber is fixedly provided on the inner wall surface of the arc plate 1 21 and the arc plate 2 31 to increase the friction between the detection rod 6 .

[0041] In a preferred embodiment, a mounting through hole is provided on a side of the annular body 1 away from the fixing assembly 2 , and one end of the mounting sleeve 32 is inserted into the mounting through hole and fixedly connected to the annular body 1 .

[0042] The working principle of the utility model is as follows: when in use, the annular body 1 is sleeved on the outside of the detection rod 6 and moved to the specified required position, and then the rotating hand wheel 34 is operated to drive the screw rod 33 to screw into the inside of the mounting sleeve 32, and the screw rod 33 moves toward the inside of the mounting sleeve 32, pushing the shaft rod 35 to slide toward the outside of the mounting sleeve 32. Due to the setting of the bearing 36, there will be no motion interference between the screw rod 33 and the shaft rod 33. During the sliding process of the shaft rod 35 toward the outside of the mounting sleeve 32, the arc plate 2 31 is driven to move in the direction close to the arc plate 1 21, thereby locking the detection rod 6 in the arc The annular body 1 is fixed on the detection rod 6 between the plate 1 21 and the arc plate 2 31 to complete the installation of the limit ring; conversely, when disassembling and adjusting the limit ring, the screw 33 is rotated in the opposite direction, and the screw 33 moves outward inside the installation sleeve 32, driving the shaft 35 to move inward inside the installation sleeve 32, and then driving the arc plate 2 31 to move away from the detection rod 6 to unlock the detection rod 6; the whole adjustment process is simple and convenient, and the position of the limit ring on the detection rod 6 can be adjusted to meet the detection of detection holes 5 at different positions and with different hole depths.
