Description

Technical Field

[0001] The utility model relates to the technical field of processing tooling, in particular to an online detection tooling for the outer circle of a spiral rotor. Background Art

[0002] Currently, the existing device for measuring the outer diameter of a product usually uses a dial indicator, that is, the dial indicator is set on a magnetic base, and then the magnetic base is adsorbed on the machine tool, and the outer diameter of the measured product is measured by the dial indicator.

[0003] The general operation method is to first clamp the standard part on the machine tool with the help of external tools, adsorb the magnetic base on the machine tool, and measure the outer diameter of the standard part with the dial indicator. At this time, a standard value appears on the dial of the dial indicator. Then, with the help of external tools, remove the standard part from the machine tool, clamp the product to be processed on the machine tool in the same way, and process the product to be processed through the sharpening device until the outer diameter of the processed product reaches the standard value, and the processing of the processed product is completed.

[0004] Although the existing measuring devices can also measure the measured products, it is very easy to touch the micrometer probe during the replacement of standard parts and processed products. Once the micrometer probe is touched accidentally or unconsciously, the standard value measured for the standard part will become invalid, which will not only lead to the quality of the processed product not meeting the standards and the risk of batch defective products, but also the standard parts and processed products are loaded on the machine tools separately, making the processing process complicated and inconvenient to operate, resulting in low processing efficiency.

[0028] Hereinafter, only certain exemplary embodiments are briefly described. As will be appreciated by those skilled in the art, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and description are to be regarded as illustrative in nature and not restrictive.

[0030] The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention.

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides an online detection tool for the outer circle of a spiral rotor, comprising: a marking piece 1, a micrometer 2 and a positioning component.

[0033] Among them, the calibration part 1 is mainly used to inspect the processed product, the micrometer 2 is set in the calibration part 1 and is used to measure the measured object, and the positioning component is set adjacent to the micrometer 2 and fixedly connected to the calibration part 1. The positioning component mainly positions and fixes the micrometer 2. First, the calibration part 1 is placed on the standard part, and the micrometer 2 is used to measure and read the standard value. Then, the micrometer 2 and the calibration part 1 are positioned and fixed by the positioning component; the tooling is moved and placed on the processed product to realize the inspection and measurement of the processed product. As the processed product is processed, the size of the processed product gradually approaches the standard value until the size of the processed product is basically consistent with the standard value, and the processing process of the processed product is completed. The processed product is the product that needs to be processed, and its shape is basically consistent with the finished product, and its size is slightly larger than the finished product. The standard part is a simulated finished part, and its size and shape are basically consistent with the finished part.

[0034] Specifically, the calibration part 1 corresponds to the product being processed and the standard part. In this embodiment, the calibration part 1 preferably has a semicircular, three-dimensional structure. A through-hole is formed at the top of the calibration part 1, adjacent to one end thereof. A micrometer gauge 2 is positioned within the through-hole, the size of which matches the measuring rod of the micrometer gauge 2. The inner circumference of the calibration part 1 aligns with the outer circumference of the standard part, meaning that the inner diameter of the calibration part 1 is substantially identical to the outer diameter of the standard part. The calibration part 1 is made of Gcr15 quenched and tempered material.

[0035] A positioning assembly is provided at one end of the alignment part 1 adjacent to the through hole, and the positioning assembly includes a fixing portion 31 and a positioning portion 32. The fixing portion 31 fits with the end face of the alignment part 1, and a threaded hole 311 is provided therethrough, and a bolt (not shown in the figure) is provided in the threaded hole 311. The threaded hole 311 on the fixing portion 31 cooperates with the bolt to realize the position locking function between the measuring rod of the micrometer 2 and the alignment part 1; preferably, the fixing portion 31 is a semicircular three-dimensional structure. The positioning portion 32 is integrally formed and arranged at the bottom of the fixing portion 31, and one side wall of the positioning portion 32 fits with the measured component, and the positioning function is realized by the positioning portion 32 fitting with the measured component; preferably, the positioning portion 32 is a semicircular three-dimensional structure. The positioning assembly is made of Gcr15 tempered material.

[0036] like Figure 1As shown, the workpiece is a cylindrical body with a tapered, variable-pitch spiral. One end of the workpiece is a large end, and the other end is a small end. The large end is slightly larger than the small end. A calibration component 1 is placed on adjacent tooth crests. This calibration component 1 performs a detection function during the workpiece processing. Specifically, when the workpiece has not yet completed the processing step (has not yet reached the standard value), the inner circumference of the calibration component 1 does not align with the outer circumference of the workpiece. When the workpiece has completed the processing step (reached the standard value), the inner circumference of the calibration component 1 aligns with the outer circumference of the workpiece. Support columns are provided on the large and small ends, each with a center hole (not shown). The workpiece is connected to the machine tool through the center hole. The machine tool drives the workpiece to rotate. During the rotation of the workpiece, a sharpening device moving along the axis of the workpiece processes the workpiece.

[0037] When doing specific operations, such as Figure 2As shown, first place the tooling on the standard part so that the inner circumference of the corresponding calibration part 1 is aligned with the outer circumference of the standard part, and the side wall of the positioning portion 32 is aligned with the end face of the standard part. Then, use the dial gauge 2 to measure the standard part to obtain the required standard value of the large end of the processed product. At the same time, the threaded hole 311 on the fixing portion 31 is engaged with the bolt to lock the position of the dial gauge 2 and the calibration part 1, thus completing the process of obtaining the standard value. In the same way, obtain the required standard value of the small end of the processed product, and at the same time, lock the dial gauge 2 and the corresponding calibration part 1 through the fixing portion 31. After obtaining the required standard values ​​for the large and small ends of the product being processed, the tooling is placed on the product being processed in the same manner as the standard values ​​were obtained, so that the inner circumference of the corresponding reference part 1 corresponds to the outer circumference of the large end of the product being processed. At this time, the outer diameter of the large end of the product being processed is larger than the inner diameter of the corresponding reference part 1, the inner circumference of the corresponding reference part 1 does not fit the outer circumference of the large end of the product being processed, and the probe of micrometer 2 does not contact the outer circumference of the large end of the product being processed. As the large end of the product being processed is processed, the size gradually decreases, the inner circumference of the corresponding reference part 1 gradually fits the outer circumference of the large end of the product being processed, the probe of micrometer 2 gradually contacts the outer circumference of the large end of the product being processed, and the pointer of micrometer 2 moves. The large end of the product being processed continues to be processed until the inner circumference of the corresponding reference part 1 is completely fitted with the outer circumference of the large end of the product being processed and the pointer of micrometer 2 points to the standard value, thus completing the processing of the large end of the product being processed. The difference between machining the small end of a product and machining the large end is that the reference piece 1 used to inspect the small end corresponds to the small end. That is, when machining the large end, there is a reference piece 1 corresponding to the large end, and when machining the small end, there is a reference piece 1 corresponding to the small end. With the aid of tooling, the product can be machined accurately and efficiently.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
