Description

Technical Field

[0001] The utility model belongs to the technical field of circlip installation, and particularly relates to a detection device for detecting whether a circlip is installed in place. Background Art

[0002] A circlip is a typical fastener, usually made of C-shaped elastic material, with functions of embedding, fastening, positioning and supporting.

[0003] In practical applications, the circlip must be installed in place, otherwise the shaft parts will become loose and fall off, causing equipment failures or accidents. Therefore, judging whether the circlip is in place is a prerequisite for using the circlip. In the prior art, for example, a circlip in-place detection tooling with the application number CN202021547146.5 can be coaxially sleeved on the shaft body with an installation cavity. The assembled circlip can be embedded in the installation groove at the bottom end of the installation cavity and can push the measuring column upward to enter the measurable area of the proximity switch. The utility model has low cost and simple structure, and can accurately judge whether the circlip is in place or enters the card slot.

[0004] However, due to the fixed inner diameter of the bottom installation groove of the above circlip in-place detection tooling, when detecting, only circlips of a fixed size can be detected. When the size of the circlip changes, the circlip cannot enter the installation groove for abutting, resulting in the situation that detection cannot be carried out.

[0005] Therefore, how to provide a detection device for detecting whether a circlip is installed in place is an urgent problem to be solved by those skilled in the art. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a detection device for detecting whether a circlip is installed in place, aiming to solve the problems mentioned in the background art.

[0016] Preferably, a groove is formed on the outer side of the lower end of the inner cylinder, and anti-slip patterns are provided at the bottom of the inner cylinder.

[0017] Preferably, a storage groove is formed on the inner side of the bottom end of the positioning sleeve, and limiting rods are circumferentially and arrayedly hinged inside the storage groove, and the tops of the limiting rods are movably abutted against the bottom of the inner cylinder.

Detailed implementation manners

[0028] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, 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 only used to explain the present utility model and are not used to limit the present utility model.

[0029] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0030] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the structure diagram of a snap ring installation in-place detection device provided by an embodiment of the present utility model includes;

[0031] Positioning cylinder 1;

[0032] Sliding groove 2, the sliding groove 2 is circumferentially and arrayedly opened on the inner wall of the positioning cylinder 1;

[0033] Lifting plate 3, the lifting plate 3 is slidably installed inside the sliding groove 2;

[0034] Positioning sleeve 4, the positioning sleeve 4 is fixedly installed at the edge of the bottom of the lifting plate 3;

[0035] Inner sleeve 5, the inner sleeve 5 is spirally installed from the outside to the inside on the inner side of the positioning sleeve 4 and its adjacent inner sleeve 5 in sequence.

[0036] In the embodiment of the present utility model, when in use, insert the hand into the middle of the innermost inner sleeve 5 and rotate it, thereby driving the inner sleeve 5 to descend, so that it can often abut against and detect a circlip capable of detecting the minimum diameter, or apply different downward forces, thereby driving other inner sleeves 5 with different quantities to move downward, so that the inner sleeve 5 extends out of the positioning sleeve 4, and thus corresponds to the diameter of the corresponding circlip;

[0037] By arranging a positioning sleeve 4 and an inner sleeve 5 with an adjustable extended position at the bottom of the lifting plate 3, corresponding adjustments can be made according to the position and size of the circlip, thereby expanding the applicable range of the current detection device and making the application range more extensive.

[0038] Such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in, as a preferred embodiment of the present utility model, a support sleeve 13 is spirally installed on the surface of the positioning cylinder 1, and the extended length of the support sleeve 13 is correspondingly set with the length values after the positioning sleeve 4 and the inner sleeve 5 extend.

[0039] In the embodiment of the present utility model, after the adjustment is completed, rotate the support sleeve 13 to make it descend along the positioning cylinder 1, and then align it with the currently extended inner sleeve 5 or positioning sleeve 4;

[0040] By arranging a liftable support sleeve 13 on the outside of the positioning cylinder 1, corresponding adjustments can be made according to the positions of the positioning sleeve 4 and the inner sleeve 5 with an adjustable extended position, thereby playing a supporting role for the positioning cylinder 1, and thus facilitating the contact and detection between the inner positioning sleeve 4 and the inner sleeve 5 with an adjustable extended position and the circlip.

[0041] Such as Figure 2 As shown in, as a preferred embodiment of the present utility model, a display head 6 is fixedly installed at the top of the positioning cylinder 1, a pressure detector 7 is fixedly installed at the bottom of the display head 6, a spring 9 is fixedly installed at the bottom of the pressure detector 7, a top plate 10 is fixedly installed at the bottom of the spring 9, and the bottom of the 101 is fixedly connected to the top of the lifting plate 3.

[0042] In the embodiment of the present utility model, during detection, make the support sleeve 13 contact the gasket at the installation position of the circlip, and make the extended inner sleeve 5 or positioning sleeve 4 contact the circlip. When the extended inner sleeve 5 or positioning sleeve 4 jacks up the lifting plate 3 and compresses the pressure detector 7 through the top plate 10 and the spring 9, and then displays on the display head 6, it can be determined that the circlip has not completely entered the groove at the installation position, and thus it can be determined that the current circlip is not installed in place, so that the installation situation of the circlip can be detected.

[0043] As shown in Figure 2 , Figure 3 and Figure 5 , as a preferred embodiment of the present utility model, the diameter value of the inner sleeve 5 gradually decreases from outside to inside, and the diameter value of the inner inner sleeve 5 is equal to the inner diameter value of the outer inner sleeve 5.

[0044] In the embodiment of the present utility model, when in use, by making the diameter value of the inner sleeve 5 gradually decrease from outside to inside, and the diameter value of the inner inner sleeve 5 is equal to the inner diameter value of the outer inner sleeve 5, various snap rings with different diameters can be frequently abutted.

[0045] As shown in Figure 2 and Figure 5 , as a preferred embodiment of the present utility model, a groove 8 is provided on the outer side of the lower end of the inner sleeve 5, and an anti-slip pattern is provided at the bottom of the inner sleeve 5.

[0046] In the embodiment of the present utility model, when in use, by providing a groove 8 on the outer side of the lower end of the inner sleeve 5, the position of the inner sleeve 5 can be conveniently constrained and limited, and by providing an anti-slip pattern at the bottom of the inner sleeve 5, the redundant inner sleeve 5 in the middle can be conveniently reversed and reset.

[0047] As shown in Figure 2 and Figure 3 , as a preferred embodiment of the present utility model, a receiving groove 11 is provided on the inner side of the bottom end of the positioning sleeve 4, and a limiting rod 12 is circumferentially and arrayedly hinged inside the receiving groove 11, and the top of the limiting rod 12 is movably abutted against the bottom of the inner sleeve 5.

[0048] In the embodiment of the present utility model, when in use, by providing a receiving groove 11 on the inner side of the bottom end of the positioning sleeve 4 and circumferentially and arrayedly hinging a limiting rod 12 inside the receiving groove 11, the top of the limiting rod 12 is movably abutted against the bottom of the inner sleeve 5, so as to constrain the inner sleeve 5 at different positions, and further avoid the situation of pulling too much or pulling wrongly when pulling out.

[0049] As shown in Figure 2 , as a preferred embodiment of the present utility model, the height value of the positioning sleeve 4 is greater than the height value of the inner sleeve 5, and the inner diameter value of the positioning sleeve 4 is equal to the diameter value of the outermost inner sleeve 5.

[0050] In the embodiment of the present utility model, when in use, by making the height value of the positioning sleeve 4 greater than the height value of the inner sleeve 5, the storage of the inner sleeve 5 is facilitated, and by making the inner diameter value of the positioning sleeve 4 equal to the diameter value of the outermost inner sleeve 5, the inner sleeve 5 can extend downward along the positioning sleeve 4.

[0051] In the above embodiment of the present utility model, a snap ring installation in-place detection device is provided. When in use, the extended length of the corresponding inner sleeve 5 is adjusted according to the diameter of the measured snap ring, so as to correspond to the position of the snap ring;

[0052] When making the adjustment, move the position of the limiting rod 12 inside the receiving groove 11, so as to release the restraint on the inner sleeve 5 at different positions;

[0053] Subsequently, insert the hand into the middle of the innermost inner sleeve 5 and rotate it, so as to drive the inner sleeve 5 to descend, so that it can often abut against and detect the snap ring with the smallest detectable diameter;

[0054] When the diameter of the snap ring corresponds to the middle inner sleeve 5, when rotating the innermost inner sleeve 5 and applying different forces downward, other different numbers of inner sleeves 5 are driven to move downward, so that the inner sleeve 5 extends out of the positioning sleeve 4, and the groove 8 on the side is exposed. Subsequently, fix the outermost extended inner sleeve 5 by hand, then press the bottom of the inner sleeve 5 on the inner side and rotate it in the reverse direction, so that the inner sleeve 5 on the inner side moves upward, so that only the outermost extended inner sleeve 5 extends out, so as to correspond to the diameter of the corresponding snap ring;

[0055] When the positioning sleeve 4 corresponds to the diameter of the snap ring, there is no need to rotate the inner sleeve 5, and directly align the positioning sleeve 4 with the top of the snap ring;

[0056] After the adjustment is completed, rotate the support sleeve 13 so that it descends along the positioning cylinder 1, so as to align with the currently extended inner sleeve 5 or positioning sleeve 4;

[0057] Subsequently, when detecting, make the support sleeve 13 contact the gasket at the snap ring installation position, and make the extended inner sleeve 5 or positioning sleeve 4 contact the snap ring. When the extended inner sleeve 5 or positioning sleeve 4 jacks up the lifting plate 3, and presses the pressure detector 7 through the top plate 10 and the spring 9, and then it is displayed on the display head 6, so as to determine that the snap ring has not completely entered the groove at the installation position, and further determine that the snap ring is not installed in place;

[0058] When there is no display, it means that the installation is in place.

[0059] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
