Abstract

The invention discloses a device and method for measuring the radial run-out of a roller part based on synchronous belt drive. The device comprises two V-shaped supports, and the central part of the lower side of the roller part is provided with a synchronous belt drive device, and the upper side of the roller part is provided with an elastic compressing device. The lower side of the roller part is provided with a flexible gauge sensor, and a signal output end of the flexible gauge sensor is connected with a computer. The method comprises the steps: enabling two ends of the roller part to be respectively placed on the two support devices; starting the synchronous belt drive device to drive the roller part to rotate; driving the elastic compressing device to descend through an external pressing device, and pressing the roller part so that the roller part rotates stably; reading the maximum and minimum values of the flexible gauge sensor in one rotating circle of the roller part; and subtracting the minimum value from the maximum value to obtain the radial run-out of the roller part. The device and method are quick and automatic in measurement, is high in universality, and is high inmeasurement precision.

Example Embodiment

[0033] The device and method for measuring the radial runout of the roller workpiece based on the synchronous belt drive of the present invention will be described in detail below in conjunction with the embodiments and the drawings.
[0034] Such as figure 1 As shown, the device for measuring the radial runout of the roller workpiece based on the synchronous belt drive of the present invention includes two V-shaped support frames 2 for supporting the two ends of the roller workpiece 1 respectively. The lower middle part of the roller workpiece 1 is provided for driving the roller workpiece 1 Rotating timing belt driving device 3, on the upper side of the roller workpiece 1 is provided with an elastic pressing device 4 for pressing the roller workpiece 1 to make the roller workpiece 1 rotate stably, and on the lower side of the roller workpiece 1 is provided with a measuring roller workpiece 1 A flexible gauge sensor 5 with radial runout, and the signal output end of the flexible gauge sensor 5 is connected to a computer.
[0035] Such as figure 1 , figure 2 As shown, the timing belt drive device 3 includes a drive motor 3.2 respectively arranged on the support block 3.1 and a support plate 3.4 located on the front side of the drive motor 3.2, and the drive shaft 3.3 of the drive motor 3.2 penetrates the support plate 3.4 is connected to the driving pulley 3.5 located on the front side of the support plate 3.4. The front side of the support plate 3.4 is provided with a support shaft 3.6 on both sides symmetrically located above the main pulley 3.5. A driven pulley 3.7 is respectively installed on the supporting shaft 3.6, and the driving pulley 3.5 and the two driven pulleys 3.7 are connected together with a synchronous driving belt 3.8 for supporting and simultaneously driving the roller workpiece 1 to rotate. When the driving motor 3.2 is started, it drives the driving pulley 3.5 to rotate, so that the synchronous driving belt 3.8 rotates and drives the roller workpiece 1 to rotate.
[0036] Such as image 3 As shown, the elastic pressing device 4 includes a pressure plate 4.1 for pressing on the upper side of the roller workpiece 1, and a support column 4.2 is fixedly connected to the upper end surface of the pressure plate 4.1. The support column 4.2 The upper end penetrates through the through hole formed on the bottom surface of the connecting cover 4.5 and is fixedly connected to the spring support plate 4.3 located in the connecting cover 4.5, the spring support plate 4.3 is connected with a spring 4.4, and the upper end surface of the spring support plate 4.3 is used for Connect external external pressure device. The external pressure applying device is an air cylinder, a hydraulic cylinder, or a displacement table.
[0037] The measuring method based on the synchronous belt-driven roller workpiece radial runout measuring device of the present invention includes the following steps:
[0038] 1) Place both ends of the roller workpiece on two supporting devices;
[0039] 2) Start the synchronous belt drive device to drive the roller workpiece to rotate, including starting the drive motor to drive the driving pulley to rotate, and the synchronous driving belt connected to the driving pulley to drive the roller workpiece to rotate.
[0040] 3) Drive the elastic pressing device down through the external pressing device, and press the roller workpiece downward to ensure the stable rotation of the roller workpiece;
[0041] 4) Read the maximum and minimum values ​​on the flexible gauge sensor during one rotation of the roller workpiece through the computer;
[0042] 5) Subtract the minimum value from the maximum value to obtain the radial runout of the roller workpiece.
