Description

Technical Field

[0001] This utility model belongs to the field of guide impeller detection and positioning technology, and in particular relates to a detection tooling for guide impellers. Background Technology

[0002] Guide impellers are an important component in fluid machinery (such as pumps, compressors, and turbines), primarily functioning to guide and regulate fluid flow to improve equipment efficiency and performance. Guide impellers typically consist of a series of fixed blades arranged around a central axis, whose angles can be adjusted as needed to control the direction and velocity of the fluid, thereby optimizing machine efficiency. Traditional inspection methods for guide impellers have the following limitations:

[0003] Early inspection methods may not have been able to ensure the precise positioning of the guide impeller during the inspection process, resulting in inaccurate inspection results. This is especially true when detailed inspection of different positions of the guide impeller is required. If the workpiece is not securely and precisely fixed, it may shift or tilt, affecting the final inspection quality. Previous inspection devices often lacked effective design to support the easy rotation or movement of the guide impeller to the required inspection position during the inspection process. This forced operators to spend extra time and effort to adjust the workpiece position, reducing work efficiency.

[0004] To address these issues, we provide a testing fixture for guide impellers. Utility Model Content

[0005] The purpose of this invention is to provide a testing fixture for a guide impeller. By combining a conical tray with a positioning component and equipping it with a rotatable positioning roller to press and position the guide impeller, the invention solves the problem of insufficient practicality of existing testing devices.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a testing fixture for a guide impeller, including a mounting ring and positioning components evenly distributed around the annular surface of the mounting ring; the positioning components include a base plate fixed to the annular surface of the mounting ring by a support column, a cylinder fixed to the middle position of the base plate, a support plate fixed to the piston rod end of the cylinder, a base fixed to the middle of the outer side of the support plate, shaft seats symmetrically fixed to both sides of the base, and a positioning roller rotatably disposed between the shaft seats;

[0008] The inner ring of the mounting ring is fixed with a conical tray, and a limiting end is fixed at the center of the conical tray, which cooperates with the central hole of the guide impeller.

[0009] The present invention is further configured such that a kit is fixed to the back end of the support plate, a guide rod is inserted inside the kit, and a mounting seat is fixed to the end of the guide rod, and the mounting seat is fixed to the edge of the base plate.

[0010] The present invention is further configured such that the bearing seat has a Z-shaped structure, and reinforcing ribs are provided at equal intervals at the outer corners of the bearing seat, and a shaft is connected between the front end of the bearing seat and the positioning roller.

[0011] The present invention is further configured such that the positioning roller abuts against the periphery of the guide impeller, and the periphery of the positioning roller is provided with anti-slip textures at equal intervals.

[0012] The present invention is further configured such that a plurality of the positioning rollers are equidistantly arranged around the axis of the mounting ring and the conical tray, and the axis of the positioning rollers is parallel to the axis of the mounting ring and the conical tray.

[0013] The present invention is further configured such that the conical surface of the conical tray is provided with hollowed-out grooves at equal intervals around its center, and the conical surface of the conical tray is supported on the inner side of the inner ring blade surface of the guide impeller.

[0014] A tooling for inspecting guide impellers is used for positioning during guide impeller inspection.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model ensures that the guide impeller is fixed in position during the testing process by setting a limiting end and cooperating with the central circular hole of the guide impeller, avoiding unnecessary tilting or offset. Combined with the tight clamping of the guide impeller circumference by the positioning component, the stability and accuracy of the testing process are further enhanced. In addition, the equidistant hollow grooves on the conical tray not only provide stable support for the guide impeller, but also reduce the contact area and the damping effect on the guide impeller, making it easier to perform rotation testing, reducing the need for external force, and making the testing process smoother.

[0017] 2. By setting a rotatable positioning roller, this utility model allows the guide impeller to rotate freely while being securely positioned, making it convenient for operators to inspect the guide impeller from multiple angles without frequently adjusting the workpiece position, thereby improving inspection efficiency and accuracy.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example

[0027] Please see Figure 1-4 This utility model is a testing fixture for a guide impeller, including a mounting ring 100 and positioning components 300 equidistantly distributed around the annular surface of the mounting ring 100. The positioning components 300 include a base plate 301 fixed to the annular surface of the mounting ring 100 by a support column, a cylinder 302 fixed to the middle position of the base plate 301, a support plate 305 fixed to the piston rod end of the cylinder 302, a base 306 fixed to the middle of the outer side of the support plate 305, shaft seats 307 symmetrically fixed on both sides of the base 306, and a positioning roller 308 rotatably disposed between the shaft seats 307. The cylinder 302 drives the piston rod to push the support plate 305 outward, so that the positioning roller 308 fixed on the support plate 305 is tightly pressed against the periphery of the guide impeller, thereby limiting the positioning of the guide impeller. At the same time, the rotation of the positioning roller itself can facilitate the rotation of the guide impeller, thus facilitating the rotation of the guide impeller for multi-position testing.

[0028] The inner ring of the mounting ring 100 is fixed with a conical tray 200. A limiting end 201 is fixed at the center of the conical tray 200. The limiting end 201 cooperates with the central hole of the guide impeller. The limiting end 201 serves as the center point. When the limiting end 201 cooperates with the central hole of the guide impeller, the position of the guide impeller is determined. Combined with the limiting of the positioning component 300, it is ensured that the guide impeller will not tilt or deviate unnecessarily during the detection process, thereby improving the accuracy and efficiency of the detection.

[0029] Specifically, the positioning roller 308 is pressed against the periphery of the guide impeller, and the periphery of the positioning roller 308 is continuously and equidistantly provided with anti-slip textures. Several positioning rollers 308 are equidistantly arranged around the axis of the mounting ring 100 and the conical tray 200, and the axis of the positioning roller 308 is parallel to the axis of the mounting ring 100 and the conical tray 200. After the positioning roller 308 is pressed against the guide impeller, the planar position of the guide impeller is fixed, but it can rotate. The anti-slip textures on the periphery of the positioning roller 308 effectively improve the frictional damping between the guide impeller and the positioning roller 308, preventing the guide impeller from slipping. The positioning shaft 308 is distributed around the conical tray 200 and combined with the conical tray 200 to achieve stable positioning of the guide impeller.

[0030] The conical tray 200 has hollowed-out grooves equidistantly arranged around its center on its conical surface, and the conical surface of the conical tray 200 is supported on the inner side of the inner ring blade of the guide impeller. The conical tray 200 provides stable support for the guide impeller while reducing its contact area and reducing the damping effect on the guide impeller, thereby facilitating the rotation detection of the guide impeller during the testing process.

[0031] Furthermore, a kit 304 is fixed to the rear end of the support plate 305, and a guide rod is inserted inside the kit 304. A mounting seat 303 is fixed to the end of the guide rod, and the mounting seat 303 is fixed to the edge of the base plate 301. The guide system formed by the kit 304 and the guide rod is used to ensure the smooth movement of the support plate 305, while the mounting seat 303 is used to install and fix the guide rod.

[0032] The bearing seat 307 has a Z-shaped structure, and reinforcing ribs are provided at equal intervals at the outer corners of the bearing seat 307. This not only improves the durability of the bearing seat 307 itself, but also indirectly improves the stability of the positioning roller 308 during use and extends the service life of the equipment. A shaft is connected between the front end of the bearing seat 307 and the positioning roller 308 to realize the rotation of the positioning roller 308 relative to the bearing seat 307.

[0033] The operation process in this embodiment is as follows:

[0034] The inspection fixture for the guide impeller is used for positioning during the inspection of the guide impeller. When using the inspection fixture, the guide impeller to be inspected is first placed on the conical tray 200, and the central hole of the guide impeller is precisely matched with the limiting end 201 to determine its center position.

[0035] Next, cylinder 302 is activated, and the piston rod pushes the support plate 305 outward. During this process, the guide system formed by the guide rod and the kit 304 ensures that the support plate 305 can move smoothly along the preset path. As the support plate 305 moves, the positioning roller 308 fixed on the outer middle base 306 gradually approaches the circumferential surface of the guide impeller. The axis of the positioning roller 308 is parallel to the axis of the mounting ring 100 and the conical tray 200, and multiple positioning rollers 308 are equidistantly distributed around the guide impeller to ensure uniform pressure distribution. When the positioning roller 308 is tightly pressed against the circumference of the guide impeller, the anti-slip texture on it increases the friction and prevents the guide impeller from sliding or accidentally falling off during the testing process.

[0036] At this time, since the positioning roller 308 can rotate freely, it not only provides stable support and positioning for the guide impeller, but also allows the guide impeller to rotate when needed. This allows the inspector to conduct a comprehensive and detailed inspection of the guide impeller from different angles and positions without having to readjust or remove the guide impeller, which greatly improves work efficiency and inspection accuracy. Furthermore, throughout the inspection process, the conical tray 200 reduces the contact area with the inner ring of the guide impeller through the setting of its hollow groove, thereby reducing frictional resistance and facilitating the rotation operation of the guide impeller.
