Description

Technical Field

[0001] This utility model relates to the field of detection device technology, specifically to a detection device for fan pulleys. Background Technology

[0002] The smoothness of the fan pulley groove directly affects the belt drive efficiency and service life. Rough surfaces or burrs on the groove surface exacerbate belt wear, increase transmission noise, and can even lead to uneven wear and breakage. This testing device, designed specifically for the structural characteristics of fan pulley grooves (primarily V-grooves and multi-wedge grooves), integrates mechanical positioning, sensor detection, and data visualization functions to achieve rapid and accurate detection of groove surface roughness (the core smoothness indicator). It is compatible with various fan pulleys with diameters of 50-500mm and groove depths of 3-20mm, and can be applied to production quality inspection, equipment maintenance, and other scenarios.

[0003] A prior art patent with publication number CN104215433A discloses a solution comprising: a driving wheel, a driven wheel, a belt, a pulley, and a sensing component; the belt connects the driving wheel and the driven wheel; the belt drives the pulley to rotate by friction; the sensing component is used to detect the rotational speed of the pulley and send a feedback signal to simulate the operation of the pulley under use conditions, so as to detect whether the pulley meets the usage standards, thereby reducing the maintenance costs required for devices using pulleys.

[0004] As existing devices are used, the shortcomings of this technology have gradually become apparent, mainly in the following aspects:

[0005] First, the existing fan pulley grooves have different wall orientations, which makes it impossible for the existing device to detect walls with different orientations, thus affecting the accuracy of the groove detection.

[0006] Secondly, because different types of fan pulleys have different diameters, existing detection devices cannot detect the grooves of fan pulleys with different diameters, thus reducing their applicability.

[0007] As can be seen from the above, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a detection device for fan pulleys. This device solves the problems of existing technologies failing to detect pulley grooves with different wall orientations due to varying wall orientations, thus affecting the accuracy of groove detection; and also addressing the limitation of existing detection devices for detecting pulley grooves with different diameters due to varying fan pulley diameters, thus reducing their applicability.

[0009] To achieve the above objectives, the present invention provides the following technical solution.

[0010] A fan pulley detection device includes a base on which a pulley support shaft is vertically rotatably mounted. The pulley support shaft is equipped with a pulley fixing assembly for securing pulleys of different diameters.

[0011] A vertical column is slidably mounted on one side of the base, and a horizontal column is slidably mounted on the vertical column. An angle adjustment shaft is rotatably mounted on the other end of the horizontal column. One end of the angle adjustment shaft is fixedly connected to a mounting base, and a dial indicator is detachably connected to the mounting base.

[0012] As an optimized solution, the pulley fixing assembly includes a support platform fixed to the pulley support shaft, a pressing platform that moves vertically up and down above the support platform, and tapered surfaces are respectively provided on the peripheral walls of the support platform and the pressing platform, with the small diameter ends of the support platform and the pressing platform facing each other.

[0013] As an optimized solution, the pressing table has a threaded hole along the axial direction, and the pulley support shaft has an external thread section that matches the threaded hole.

[0014] As an optimized solution, a rotary handle is fixedly connected to the upper end of the clamping table.

[0015] As an optimized solution, a drive motor is fixedly connected to the lower surface of the base, and the output shaft of the drive motor is fixedly connected to the lower end of the pulley support shaft.

[0016] As an optimized solution, a slide rail is horizontally fixed to the base, a slide block is slidably mounted on the slide rail, and the lower end of the vertical column is vertically fixed to the slide block.

[0017] As an optimized solution, a fixing knob is threaded onto the slide block, and the end of the fixing knob abuts against the slide rail.

[0018] As an optimized solution, the vertical column is fitted with a sliding sleeve along its vertical direction, and one end of the horizontal column is fixed to the side wall of the sliding sleeve.

[0019] As an optimized solution, a second fixing knob is horizontally threaded onto the side wall of the sliding sleeve, and a guide groove is vertically formed on the side wall of the vertical column, with the end of the second fixing knob abutting against the guide groove.

[0020] As an optimized solution, several height fixing slots are arranged in parallel from top to bottom in the guide groove, and the end of the second fixing knob abuts against one of the height fixing slots.

[0021] As an optimized solution, a fixing knob three is horizontally threaded to the end of the horizontal column near the angle adjustment shaft. Several angle fixing grooves are opened along the circumference of the angle adjustment shaft, and the end of the fixing knob three abuts against one of the angle fixing grooves.

[0022] As an optimized solution, the mounting base is provided with an insertion hole, the column end of the dial indicator is inserted into the insertion hole, and a fixing knob four is threadedly connected to the side wall of the mounting base, the end of the fixing knob four abutting against the column end of the dial indicator.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] The center hole of the fan pulley is horizontally inserted into the pulley support shaft and supported by the support platform. Then, the clamping sleeve is tightened to fix the fan pulley. The support platform and the clamping platform are respectively provided with conical surfaces on their peripheral walls. The small diameter ends of the support platform and the clamping platform are set opposite each other, which can fix the center hole of fan pulleys of different diameters. The conical surfaces can also be used to position and center the fan pulley, making fixing quick and easy.

[0025] By sliding the vertical column horizontally and the horizontal column vertically, the dial indicator can be matched to the height and position of the pulley groove of fans with different diameters.

[0026] The dial indicator can be adjusted by swinging and tilting its angle shaft, allowing it to be used to test the groove walls of fan pulleys facing different directions. By placing the dial indicator's testing end against the wall and driving the fan pulley to rotate via a drive motor, the smoothness of the surface can be tested. This method is convenient, fast, and expands the range of applications. Attached Figure Description
