Description

Technical Field

[0001] The utility model relates to the technical field of dynamic balance detectors, in particular to a dynamic balance detector for fan testing. Background Art

[0002] Fans help circulate indoor air by generating airflow, dissipating heat, lowering the temperature, and providing a comfortable environment. After the fan is processed, a dynamic balancing tester is needed to detect whether there is imbalance or vibration when the fan rotates, and to detect possible problems inside the fan such as structural instability and shaft offset. This helps to detect potential faults in a timely manner and repair them, and can help manufacturers ensure that the quality of their products meets standards.

[0003] The dynamic balancing tester needs to clamp the fan blades and drive them to rotate. The sensor detects vibration, imbalance and rotation axis position, etc. Here, the fan blades need to be fixed on the drive motor used for detection, and tools such as clamps and screws are needed as fixings, which makes disassembly and assembly cumbersome and time-consuming. Therefore, we propose a dynamic balancing tester for fan testing to solve the existing problem. Utility Model Content

[0004] The purpose of the utility model is to address the problems existing in the background technology and to provide a dynamic balance detector for fan testing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dynamic balancing tester for fan testing, comprising a body, a mounting seat, a cone plate, a cone sleeve, a support ring, a clamping block 1 and a clamping block 2, wherein the upper end of the body is provided with a hydraulic rod 1 located inside the mounting seat, the upper end of the hydraulic rod 1 is provided with a motor, the upper end of the motor is provided with a cone plate, a support ring is provided above the mounting seat, a rotating ring rotatably mounted inside the ring seat is provided at the lower end of the support ring, a guide plate 1 distributed in a ring array is provided at the upper end of the support ring, a spring 1 is provided at one end of each of the springs, and a clamping block 1 is provided at one end of each of the springs.

[0006] When using a dynamic balancing tester for fan testing in this solution, the fan blades are placed on the outer side of the upper end of the clamping block 1. At this time, the hydraulic rod 1 drives the motor and the cone plate to lift. After the cone plate is lifted, the clamping block 1 is squeezed from the inside to the outside. Because the cone plate 1 is elastically supported by the spring 1, the cone plate 1 moves synchronously to the outside and squeezes the inner wall of the fan blade installation. The inner wall of the fan blade is supported, and because the support for the spring 1 is supported by the support ring, the support ring is rotatably installed inside the upper end of the mounting seat through the rotating ring. When the motor is running, the clamping block 1 and the fan blade are driven to rotate, and dynamic balancing detection is performed through the machine body.

[0007] Preferably, the lower end and outer walls of the rotating ring are rotatably mounted with balls distributed in a circular array. The outer wall of the cone plate is conical, and the lower end of the clamping block is curved. When the rotating ring rotates within the ring seat, the balls rotate on the inner wall of the upper end of the ring seat, reducing the rotational resistance of the rotating ring and providing effective rotational support for the rotating ring. The curved lower end of the clamping block reduces the resistance and wear experienced by the cone plate when passing through the clamping block.

[0008] Preferably, one end of the clamping block is provided with a guide rod 1 located within the spring 1 and slidably mounted within the guide plate 1. The front end of the body is provided with a control panel. The control panel displays detection data from the body sensor and controls the body. When the guide plate 1 is elastically supported by the spring 1, the guide rod 1 is slidably supported within the guide plate 1, and the clamping block 1 connected to the guide rod 1 is slidably guided, thereby limiting the spring 1 during the extension and retraction process, thereby preventing the spring 1 from deflecting during the extension and retraction process.

[0009] Preferably, a second hydraulic rod is provided at the upper end of the machine body, a fixed plate is provided at the upper end of the second hydraulic rod, and a cone sleeve is provided at the upper end of the fixed plate. The cone sleeve is driven to move longitudinally by the second hydraulic rod.

[0010] Preferably, the upper end of the body is provided with brackets arranged in an annular array and located outside the cone sleeve. A second guide plate is provided on the upper end of each bracket. Slide sleeves arranged in an annular array are embedded and mounted within the fixed plate. The upper end of the body is provided with support rods slidably mounted within the slide seat. A support platform is provided on the upper end of each support rod. The support platform is used to support objects. When the cone sleeve and fixed plate are raised synchronously, the positioning rod slides within the slide sleeve, ensuring the stability of the support platform and the stable longitudinal movement of the cone sleeve.

[0011] Preferably, one end of the second guide plate is provided with a second spring, one end of the second spring is provided with a second clamping block, one end of the second clamping block is provided with a connecting rod, and the lower end of the connecting rod is provided with a ball located inside the tapered sleeve. The connecting rod is connected to one end of the second clamping block. When the ball is squeezed by force, the friction and resistance of the tapered sleeve squeezing the ball are reduced, and the squeezing force is applied to the second clamping block through the ball and the connecting rod, achieving synchronous displacement of the second clamping block.

[0012] Preferably, one end of the second clamping block is provided with a second guide rod located inside the second spring and slidably mounted inside the second guide plate. The second guide plate elastically supports the second clamping block via the second spring and slidably guides the second clamping block via the second guide rod, thereby limiting the position of the second spring during the extension and retraction process and preventing the second spring from deflecting outwards during the extension and retraction process.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The utility model uses elastically mounted clamping blocks distributed in a ring array to synchronously move outward under the pressure of the cone plate. The clamping blocks support and clamp the center of the fan blade at multiple points. The fixing and disassembly processes are controlled by the motor-driven cone plate, and the cone plate is driven by the motor to rotate, driving the clamping structure and the clamped fan blade to rotate. The rotated fan blade is tested by the machine body (dynamic balancing tester). During the testing process, the fan is easy to disassemble and assemble, which provides assistance for testing.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-Figure 5As shown, the utility model proposes a dynamic balancing tester for fan testing, including a body 1, a mounting seat 4, a cone plate 5, a cone sleeve 6, a support ring 9, a clamping block 11 and a clamping block 2 3. The upper end of the body 1 is provided with a hydraulic rod 15 located inside the mounting seat 4, the upper end of the hydraulic rod 15 is provided with a motor 13, the upper end of the motor 13 is provided with a cone plate 5, a support ring 9 is provided above the mounting seat 4, the lower end of the support ring 9 is provided with a rotating ring 14 rotatably mounted inside the ring seat 7, the upper end of the support ring 9 is provided with a guide plate 10 distributed in a ring array, one end of the guide plate 10 is provided with a spring 12, and one end of each spring 12 is provided with a clamping block 11;

[0024] The lower end and the outer walls of both sides of the rotating ring 14 are rotatably mounted with rolling balls distributed in a ring array. The outer wall of the cone plate 5 is a conical surface, and the lower end of the clamping block 11 is an arc surface.

[0025] A guide rod 8 is provided at one end of the clamping block 11 and is located inside the spring 12 and is slidably installed inside the guide plate 10. A control panel 2 is provided at the front end of the body 1.

[0026] Implementation steps based on Example 1: The fan blades are usually integrated and sleeved on the outer wall of the output shaft of the motor, rotating with the motor. The sleeve is an annular structure as a whole. The fan blade annular mounting part is sleeved on the outer side of the upper end of the clamping plate. At this time, the hydraulic rod 15 drives the cone plate 5 to lift and squeezes the clamping block 11 by extrusion. The clamping block 11 applies the extrusion force to the spring 12, thereby driving the clamping block 11 to move away from each other, supporting the sleeve on the inner wall of the fan blade, and then fixing the fan blade, avoiding the use of additional fixing parts and fixing tools. The fan blade is conveniently fixed by extrusion, and when disassembling, it is only necessary to drive the cone plate 5 to descend by the hydraulic rod, so that the spring 12 releases the extrusion force, thereby ending the extrusion fixation of the fan blade;

[0027] At the same time, when the fan blades are fixed, the motor 13 drives the cone plate 5 to rotate, and the friction force drives the clamping block, the rotating ring 14 and the fan blades to rotate. A variety of dynamic balance detection sensors are arranged inside the body 1. The rotating fan blades are detected by the sensors to understand the dynamic balance of the fan blades. The detection process of the fan blades is convenient and time-saving.

[0028] like Figure 1-Figure 5 As shown, the dynamic balance detector for fan testing proposed by the present invention is compared with the first embodiment, and this embodiment further includes: a hydraulic rod 20 is provided at the upper end of the body 1, a fixing plate 21 is provided at the upper end of the hydraulic rod 20, and a cone sleeve 6 is provided at the upper end of the fixing plate 21;

[0029] The upper end of the body 1 is provided with brackets 23 distributed in an annular array and located outside the cone sleeve 6. The upper end of each bracket 23 is provided with a guide plate 24. The interior of the fixed plate 21 is embedded with a sliding sleeve 18 distributed in an annular array. The upper end of the body 1 is provided with a support rod 19 slidably installed inside the slide seat. The upper end of the support rod 19 is provided with a support platform 26.

[0030] A second spring 16 is provided at one end of the second guide plate 24, a second clamping block 3 is provided at one end of the second spring 16, a connecting rod 17 is provided at one end of the second clamping block 3, and a ball 22 located inside the tapered sleeve 6 is provided at the lower end of the connecting rod 17;

[0031] One end of the second clamping block 3 is provided with a second guide rod 25 located inside the second spring 16 and slidably mounted inside the second guide plate 24;

[0032] In this embodiment, the temperature of the motor 13 sometimes needs to be tested during the fan blade detection process. At this time, the fan needs to be detected as a whole. The fan is placed on the support platform 26, and the hydraulic rod 20 operates to drive the cone sleeve 6 to lift, thereby driving the cone sleeve 6 to squeeze the ball 22. The ball 22 is forced to drive the connecting rod 17 to pull the clamp 2 3. The clamp 2 3 is forced to apply a pulling force to the spring 2 16. The spring 2 16 is pulled up by the force, thereby driving the clamp 2 3 to clamp the outer wall of the fan. The fan is operated after power is turned on, and dynamic balance detection is performed through the sensor of the body 1 itself. The dynamic balance detection device can directly detect the fan blades and the entire fan, and the detection flexibility is improved.

[0033] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solutions of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
