Description

Technical Field

[0001] This utility model relates to the field of testing tooling technology, and in particular to a multifunctional valve plate testing device. Background Technology

[0002] As a core functional component of a valve, the valve plate's surface flatness, sealing performance, and structural integrity directly affect the valve's overall performance and service life. Therefore, it is necessary to rigorously inspect the valve plate using specialized testing equipment to ensure product quality meets production standards. However, a multi-functional valve plate testing device still has some problems in its use:

[0003] During the inspection process, staff need to frequently disassemble and readjust the valve plate to inspect its back, sides, and concealed areas. This not only involves cumbersome procedures, significantly increasing labor costs and operational complexity, but also risks causing valve plate positioning deviations due to repeated disassembly and reassembly, and even secondary damage such as scratches on the valve plate surface. Furthermore, the blind spots in the inspection view created during repeated disassembly and reassembly make it difficult to ensure complete inspection coverage, potentially missing minute defects on the valve plate surface and adversely affecting the reliability of the inspection results.

[0004] Enterprises need to customize special testing fixtures for valve plates of different sizes, which not only significantly increases the investment cost of testing equipment, but also requires dedicated storage space for various fixtures, increasing site management costs. In addition, when testing valve plates of different sizes, it is necessary to frequently change fixtures and readjust them, which prolongs the test preparation time, reduces the overall test efficiency, and makes it difficult to meet the rapid testing needs of multiple batches and multiple specifications of valve plates in modern production. Utility Model Content

[0005] The purpose of this invention is to provide a multifunctional valve plate detection device, which solves the above-mentioned problems.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a multifunctional valve plate detection device, including a base plate, a support frame and a positioning rod. A guide rail is provided at the middle position of the top of the base plate, and sliders are provided at both ends of the top of the guide rail. A support frame is installed on the top of the sliders, and positioning sleeves are fixed at both ends of the support frame. A positioning rod is provided at one end of the two support frames opposite to each other.

[0007] Preferably, the positioning sleeve has a bearing inside, a retaining ring is installed at the end of the bearing, a rotating rod is fixed inside the bearing, and the positioning rod is fixed to one end of the rotating rod.

[0008] Preferably, the slider has screw holes at both ends, the support frame has pin holes at both ends, and pin holes are provided at the bottom of the pin holes. Pin holes are provided at the bottom of the pin holes. Pin holes are provided at both ends inside the slider and are located inside the two screw holes. Pin holes are provided inside pin holes and pin holes. Pin holes are provided inside the screw holes.

[0009] Preferably, the screw holes are symmetrical on both sides of the centerline of the slider, and the second pin hole is symmetrical on both sides of the bottom centerline of the support frame.

[0010] Preferably, the screw hole has an internal thread, the fixing bolt has an external thread, the screw hole is threaded to the fixing bolt, and the fixing pin is interference-fitted with pin hole one and pin hole two.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides a multifunctional valve plate detection device. A positioning rod is connected to a support frame via bearings. Utilizing the rolling characteristics of the bearings, the positioning rod can rotate freely around its own axis inside the support frame. When the valve plate is installed between two positioning rods, it can rotate synchronously with the positioning rods, enabling multi-angle and omnidirectional detection of the valve plate. This rotational detection mechanism overcomes the problem of limited detection angles under traditional fixed installation methods, effectively eliminating blind spots. It allows operators to complete the detection of all surfaces and parts of the valve plate without frequent disassembly and adjustment of the valve plate position, significantly reducing operational complexity and improving the convenience and completeness of the detection coverage.

[0013] 2. This utility model provides a multifunctional valve plate detection device. By applying external force to push the support frame fixed to the slider, the slider slides linearly along the top of the guide rail, driving the positioning rods to move synchronously, thus achieving dynamic adjustment of the distance between the two positioning rods. After the distance is adjusted to the target position matching the size of the valve plate to be tested, the fixing bolt is rotated. Through the threaded engagement between the fixing bolt and the screw hole, the fixing bolt protrudes downward from the bottom of the screw hole and tightly abuts against the top of the guide rail. The position of the support frame is fixed by static friction, completing the distance locking. It can be matched with valve plates of different sizes and specifications, broadening the applicability of the tooling, eliminating the need for separate special tooling for valve plates of different sizes, and reducing the investment cost of the detection equipment.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0021] Combination Figures 1 to 4 As shown, the present invention provides a multifunctional valve plate detection device, which includes a base plate 1, a support frame 4 and a positioning rod 6. A guide rail 2 is provided at the middle position of the top of the base plate 1, and sliders 3 are provided at both ends of the top of the guide rail 2. The support frame 4 is installed on the top of the sliders 3, and positioning sleeves 5 are fixed at both ends of the support frame 4. A positioning rod 6 is provided at one end of each of the two support frames 4 facing each other.

[0022] The positioning sleeve 5 has a bearing 42 inside, a retaining ring 43 is installed at the end of the bearing 42, a rotating rod 41 is fixed inside the bearing 42, and the positioning rod 6 is fixed to one end of the rotating rod 41.

[0023] The slider 3 has screw holes 31 at both ends inside, and the support frame 4 has pin holes 33 at both ends at the bottom. Pin holes 32 are provided at the bottom of pin holes 33. Pin holes 32 are located at both ends inside the slider 3 and inside the two screw holes 31. Pin holes 34 are provided inside pin holes 32 and pin holes 33. Pin bolts 35 are provided inside screw holes 31.

[0024] The screw hole 31 is symmetrical on both sides of the center line of the slider 3, and the pin hole 33 is symmetrical on both sides of the bottom center line of the support frame 4.

[0025] The screw hole 31 has an internal thread, and the fixing bolt 35 has an external thread. The screw hole 31 is threadedly connected to the fixing bolt 35, and the fixing pin 34 is interference-fitted with pin hole 1 32 and pin hole 2 33.

[0026] Specifically,

[0027] The fixing pin 34 is inserted into the pin hole 32 and the pin hole 33. The fixing pin 34 is interference-fitted with the pin hole 32 and the pin hole 33 to assemble the support frame 4 and the slider 3. After the assembly is completed, the axes of the rotating rods 41 on the two support frames 4 are concentric.

[0028] The hole for mounting the bearing 42 on the support frame 4 and the two pin holes 33 at the bottom of the support frame 4 must be in the same plane;

[0029] This device can be used to test valve plates of various models and specifications by simply adding a corresponding positioning shaft.

[0030] In the valve plate detection system, the core execution and positioning components include: a guide rail 2, a sliding slider 3, a support frame 4 fixedly connected to the slider 3, a built-in bearing 42, a positioning rod 6 for valve plate mounting, and a fixing pin 34 and a fixing bolt 35 for position locking. These components mechanically cooperate to form a complete valve plate positioning and adjustment system. The slider 3 and guide rail 2 form a sliding pair, the bearing 42 and positioning rod 6 form a rotating pair, and the fixing pin 34, fixing bolt 35, screw hole 31, pin hole one 32, and pin hole two 33 constitute the locking mechanism.

[0031] During testing, the valve plate is directly installed between two positioning rods 6. As the core supporting component of the valve plate, the positioning rods 6 must be spaced to match the size of the valve plate to ensure stability after installation.

[0032] Rotation detection implementation mechanism

[0033] Because the positioning rod 6 is connected to the support frame 4 via the bearing 42, the rolling characteristics of the bearing 42 allow the positioning rod 6 to rotate freely around its own axis inside the support frame 4. When the valve plate is installed between the positioning rods 6, it can rotate synchronously with the positioning rods 6, thereby realizing multi-angle and all-round detection of the valve plate, solving the problem of blind spots in detection during fixed installation, and improving the integrity of detection.

[0034] The spacing adjustment of the positioning rod 6 is based on the sliding mechanism of "slider 3-guide rail 2", and the specific process is divided into three stages:

[0035] When an external force is applied to push the support frame 4, since the support frame 4 is fixedly connected to the slider 3, the slider 3 will slide linearly along the top of the guide rail 2, causing the positioning rod 6 to move synchronously, thereby realizing the dynamic adjustment of the distance between the two positioning rods 6.

[0036] After the spacing of the positioning rods 6 is adjusted to the target position that matches the size of the valve plate to be tested, the fixing bolt 35 is rotated. The fixing bolt 35 gradually protrudes downward from the bottom of the screw hole 31 through the threaded engagement with the screw hole 31 until it is tightly abutted against the top of the guide rail 2. The static friction between the fixing bolt 35 and the guide rail 2, combined with the fixing pin 34, restricts the sliding of the slider 3 along the guide rail 2, thereby fixing the position of the support frame 4.

[0037] The core advantage of this adjustment system lies in its size adaptability: by adjusting the spacing of the positioning rods 6, valve plates of different sizes and specifications can be matched, ensuring the coaxiality and stability of the valve plates during installation, and providing a mechanical basis for subsequent testing.
