Description

Technical Field

[0001] This utility model relates to the field of mechanical testing technology, and in particular to a device for detecting the installation position of an elastic retaining ring for holes. Background Technology

[0002] The brake control valve is a common component in hydraulic motors. It is very important to install the valve in place using a flexible retaining ring. If it is not installed properly, the brake control valve may fall off, causing damage to the component or the hydraulic motor.

[0003] In existing technologies, manual inspection is usually performed by rotating the snap ring clamp. However, manual inspection has large errors and low efficiency. On the other hand, the method of determining the installation position by contacting the detection head with the retaining ring and using sensors and probes may be affected by the surrounding electromagnetic environment, resulting in signal distortion and poor environmental adaptability. Utility Model Content

[0004] In view of this, the present invention proposes a hole elastic retaining ring installation position detection device, which aims to solve the problems existing in the prior art.

[0005] Specifically, the present invention provides a hole elastic retaining ring installation position detection device, comprising:

[0006] Guide sleeve for mating with the valve body plane;

[0007] A measuring shaft for detecting the mounting position of the elastic retaining ring for the hole is coaxially disposed inside the guide sleeve;

[0008] A spring for resetting the measuring shaft is provided outside the measuring shaft;

[0009] A retaining ring is provided inside the guide sleeve to axially limit the measuring shaft;

[0010] And a measuring head provided on the measuring shaft for engaging with the plane of the elastic retaining ring in the detection hole.

[0011] Based on the above scheme, the guide sleeve is a stepped shaft structure with a large outer diameter at one end and a small outer diameter at the other end;

[0012] The large-diameter end of the guide sleeve fits into the plane of the valve body, and the small-diameter end of the guide sleeve is provided with stepped surfaces of different heights along the radial or axial direction to serve as a detection reference surface.

[0013] Based on the above scheme, three stepped surfaces of different heights are provided radially on the end face of the small-diameter end of the guide sleeve.

[0014] Based on the above scheme, the measuring shaft slides relative to the guide sleeve.

[0015] Based on the above scheme, the inner side of the guide sleeve is provided with a spring seat hole for accommodating the spring, and the diameter of the spring seat hole is larger than the outer diameter of the spring.

[0016] Based on the above scheme, a boss for abutting the spring is provided at the end of the measuring shaft.

[0017] Based on the above scheme, it also includes: the measuring head is fixedly connected to the measuring shaft by screws, and a washer is provided between the measuring head and the screws to distribute pressure and protect the connection surface.

[0018] Compared with existing technologies, this invention inserts a measuring head into the detection hole, aligning it with the plane of the elastic retaining ring. Then, it presses down on the guide sleeve, ensuring a tight fit with the valve body plane. The installation position of the elastic retaining ring is determined by observing the T-face relationship between the measuring shaft and the guide sleeve of the corresponding model. This device is safe, reliable, and resets quickly, offering strong versatility for different product models. Furthermore, it features a simple structure, easy manufacturing, low cost, and reusability. Attached Figure Description

[0023] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specified, embodiments and features of the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figure 1 As shown, this application provides a specific embodiment of a hole elastic retaining ring installation position detection device, the hole elastic retaining ring installation position detection device comprising:

[0025] Guide sleeve 1 is used to fit with the valve body plane to ensure accurate positioning during testing;

[0026] A measuring shaft 2, which is used to detect the installation position of the elastic retaining ring for the hole, is coaxially arranged inside the guide sleeve 1.

[0027] A spring 3 is provided outside the measuring shaft 2 to reset the measuring shaft 2;

[0028] A retaining ring 4 is provided inside the guide sleeve 1 to axially limit the measuring shaft 2;

[0029] And a measuring head 5 provided on the measuring shaft 2 for extending into the detection hole and engaging with the plane of the elastic retaining ring for the hole.

[0030] Specifically, the measuring head 5 is fixedly connected to the measuring shaft 2 by a screw 6. When the screw 6 is used to tighten the measuring shaft 2, the head of the screw 6 presses directly on the surface of the measuring head 5, which can easily cause indentations, damage, or loosening of the surface. Therefore, in order to distribute the pressure and protect the connected surface, a washer 7 is placed between the measuring head 5 and the screw 6. This design also increases the contact area between the screw 6 and the measuring head 5, making the tightening more stable.

[0031] like Figure 2 As shown, the guide sleeve 1 provides guidance for the measuring shaft 2 in the direction of movement, ensuring that the measuring shaft 2 moves in a straight line and improving detection accuracy. Specifically, the guide sleeve 1 is a stepped shaft structure with a large outer diameter at one end and a small outer diameter at the other end. The large-diameter end of the guide sleeve 1 is in contact with the plane of the valve body. In order to provide multiple detection reference surfaces, three stepped surfaces of different heights, namely T1, T2, and T3, are radially distributed on the end face of the small-diameter end of the guide sleeve 1. T1, T2, and T3 are three different reference surfaces on the guide sleeve 1. Each T-surface represents a "qualified installation position" reference surface corresponding to a detection state or product model. The corresponding product code is engraved on the end face of T1, T2, and T3 near the outer edge.

[0032] During testing, the end face of measuring shaft 2 is compared with the T-face of the corresponding model. If the end face of the measuring shaft is flush with or lower than the T-face, it is considered qualified; otherwise, it is considered unqualified.

[0033] The aforementioned reference plane is a radial plane, which can make full use of space in the circumferential direction to satisfy the uniformity of stress distribution.

[0034] As another implementation of the T1, T2, and T3 surfaces on the guide sleeve 1, three stepped surfaces of different heights are distributed axially on the end face of the small-diameter end of the guide sleeve 1. The axial surfaces can provide better axial support and positioning, and enhance the stability of the structure.

[0035] As a specific implementation, the inner wall of the guide sleeve 1 is provided with a spring seat hole for accommodating the spring 3, the diameter of the spring seat hole being slightly larger than the outer diameter of the spring to allow the spring to extend and retract freely; a boss is provided at the end of the measuring shaft 2 for abutting the spring 3.

[0036] like Figure 3 As shown, the specific testing process during use is as follows:

[0037] 1. Insert measuring head 5: Insert measuring head 5 into the detection hole and mate it with the plane of the elastic retaining ring. This step ensures accurate contact point during detection.

[0038] 2. Press guide sleeve 1: Press the guide sleeve to make it fit tightly with the valve body plane. This step ensures accurate positioning during testing.

[0039] 3. Observe measuring shaft 2: Determine whether the installation position of the elastic retaining ring for the hole is qualified by observing the T-face relationship between the measuring shaft 2 and the guide sleeve 1 of the corresponding model.

[0040] Acceptance criteria: If the measuring shaft 2 is flush with or lower than the T-surface (T1 / T2 / T3) of the corresponding model of the guide sleeve 1, it indicates that the elastic retaining ring for the hole is installed in place, and the test result is qualified.

[0041] Non-compliance standard: If the measuring shaft 2 is higher than the T-face of the corresponding model of the guide sleeve 1, it indicates that the elastic retaining ring for the hole is not installed properly, and the test result is non-compliance.

[0042] This invention can conveniently and accurately detect the installation position of elastic retaining rings for various product holes; it has the following advantages: first, it has a simple structure, which improves work efficiency and detection accuracy; second, it has high versatility, can measure the installation position of elastic retaining rings for various product holes, and has strong practical value.

[0043] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
