Description

TECHNICAL FIELD

[0002] Radial runout refers to the maximum variation of the distance between each point on the actual surface of the measured rotating surface in the same cross section and the reference axis. The measured radial runout value can be used to determine whether the current shaft part is within the set tolerance value and whether it meets the process standard. At the same time, more detailed detection is required for the overall detection of some shaft parts with high precision requirements.

[0003] In the prior art, when detecting radial runout, the worker usually clamps the workpiece between two top pins, and then detects by moving the detection pin along the axial distance of the shaft part surface.

When using a dial gauge for detection, the numerical value on the dial gauge is not obvious, and the part cannot be intuitively determined as qualified or not, which reduces the detection efficiency. Therefore, a device is needed that can automatically adjust the position of the detection pin according to the diameter of the shaft part and intuitively display the unqualified area to avoid poor practicality and low detection efficiency.

By using the inclined side of the pressure arc block 49, the shaft part can be quickly locked in several pressure arc blocks 49 during the clamping process. The damping pad further increases the fixation of the shaft part and improves the accuracy of the test data.

[0025] In this embodiment, as Figures 1 to 10 As shown, a method for using a radial runout detection device for shaft-type parts includes the following steps: S1: The operator places the shaft part horizontally between two inclined frames 33 and adjusts the distance between the two inclined frames 33 by controlling the self-locking rod 34, thereby controlling the height of the shaft part so that the center of one side is on the same horizontal line as the adjacent ejector pin 2. Then, by controlling the ejector pin 2 on one side, the shaft part is moved to the ejector pin 2 on the other side, so that the shaft part is located between the two ejector pin 2 and fixed. S2: When the operator clamps the shaft part between the two rotating pin seats 2 by moving the rotating pin seat 2, the end of the shaft part cooperates with the pressing arc block 49. This causes the sliding drive rod 46 to slide within the sliding track 42 via the L-shaped support rod 48 and the arc plate 47. Furthermore, through the cooperation of the connecting rod 45 and the arc groove 44, the reaction plate 43 rotates at the side end of the sliding seat 41, causing the drive bevel gear 511 to rotate synchronously. This causes the drive toothed rod 512 to move up and down on the limit frame 513 according to the diameter of the shaft part. This, in turn, causes the measuring arm 516 to move synchronously via the L-shaped connecting rod 515. When the diameter of the shaft part is greater than the initial value, the drive toothed rod 512 will move downwards; when the diameter is less than the initial value, the drive toothed rod 512 will move upwards. This ensures that the measuring arm 516, driving the probe 526, remains on the surface of the shaft part, and that the first spring... The spring telescopic rod 525 is in a charged state, and then the shaft part is rotated by the pin rotating seat 2. The electric push rod 524 is controlled to work and randomly select the test position on the surface of the shaft part. This causes the recording seat 521 to move along the measuring arm 516 through the square frame 523. When the runout range of the test area of ​​the shaft part exceeds the standard value, the probe 526 drives the first spring telescopic rod 525 to retract, thereby causing the contact block 527 to move down. This, in turn, cooperates with the squeezing block 531, thereby causing the recording pen 528 to move down under the cooperation of the contact ring 529 and the compression spring 530. When the runout range of the test area of ​​the shaft part is less than the standard value, the first spring telescopic rod 525 extends, thereby causing the contact block 527 to squeeze to the side of the control rod 532. This causes the control rod 532 to move horizontally under the action of the second spring telescopic rod 533, and then causes the recording pen 528 to move down under the action of the wedge block 534. S3: in the process of moving the recording seat 521 by the electric push rod 524, the synchronous control driving motor 64 unwinds the paper roll 61, and drives the winding roller 62 through the transmission belt 63 to wind the paper, thereby driving the auxiliary disc 65 to rotate synchronously, through the cooperation of the setting of the poking roller 66 and the poking plate 74, driving the poking block 72 to move away from the auxiliary frame 67 through the spring damping telescopic rod 73, and through the hinged rod 71, driving the two auxiliary blocks 68 to approach in the cooperation groove 69, thereby driving the two limiting rollers 70 to approach each other, ensuring that the unwinding roller 61 will not wrinkle when discharging paper, so that it can smoothly discharge paper, and in the process of continuous rotation of the auxiliary disc 65, the two limiting rollers 70 can always keep close, so that in the process of each descent of the recording pen 528, the paper can be recorded.
