Description

Technical Field

[0001] This utility model relates to the technical field of machining measurement devices, and particularly to a tooling for measuring the dimensions of incomplete circles. Background Technology

[0002] Due to design requirements, in the manufacturing of certain parts, it is necessary to machine incomplete circles (hereinafter referred to as arcs) on the parts.

[0003] Since the arc segments machined on a part cannot form a complete circle, they cannot be directly measured using measuring tools (such as an inside micrometer). Generally, when measuring this arc, a radius gauge or a three-dimensional coordinate measuring machine is used. However, the use of a radius gauge has great limitations, and the measurement error increases as the diameter of the circle increases. On the other hand, a three-dimensional coordinate measuring machine cannot be operated on the production site, and the operation is time-consuming and costly, and it cannot monitor the actual dimensions of the arc in real time during the machining process. Utility Model Content

[0004] In view of the above problems, this utility model provides a tooling for measuring the dimensions of an incomplete circle, the purpose of which is to reduce the difficulty of measuring the actual dimensions of the arc during the part processing.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A fixture for measuring the dimensions of an incomplete circle is provided, comprising: a fixture body detachably mounted on a part; a compensation component mounted on the fixture body and capable of being processed synchronously with the arc to be processed; wherein the straight line containing the centers of the compensation component and the arc to be processed can pass through the arc to be processed; and a measuring component for measuring the diameter between the compensation component and the arc to be processed.

[0007] Furthermore, the compensation component is telescopically mounted on the tooling body and can move along the radial direction of the arc.

[0008] Furthermore, a nut is welded onto the main body of the tooling, and the compensation component and the nut are connected by threads.

[0009] Furthermore, the tooling body is detachably mounted to the part using bolts.

[0010] Furthermore, the main body of the tooling is made of aluminum alloy.

[0011] Furthermore, the measuring component is an inside micrometer.

[0012] The beneficial effects of this utility model are as follows: by using this utility model, the arc can be measured in real time during the processing, eliminating the need for radius gauges and three-dimensional coordinate instruments; it greatly reduces the difficulty of measuring the actual size of the arc in real time during the processing of parts, improves the stability and accuracy of arc size measurement, and can effectively improve the product quality and stability of parts. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the overall structure of the dimensional measuring fixture provided in the embodiments of this application.

[0014] Among them, 1. Part; 11. Arc to be processed; 2. Tooling body; 3. Compensation component. Detailed Implementation

[0015] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0016] Reference Figure 1 As shown in the figure, this application discloses a tooling for measuring the dimensions of an incomplete circle, including: a tooling body 2, which is detachably mounted on a part 1; a compensation component 3, which is mounted on the tooling body 2 and can be processed synchronously with the arc 11 to be processed; wherein the straight line containing the center of the compensation component 3 and the arc 11 to be processed can pass through the arc 11 to be processed; and a measuring component for measuring the diameter between the compensation component 3 and the arc 11 to be processed.

[0017] In practical use, when machining an incomplete circle (i.e., arc) on part 1, the compensation component 3 is machined synchronously by a machining equipment (such as a milling machine / machining center), which can form a complete diameter between the compensation component 3 and the arc. The actual radius of the arc during the machining process can be obtained by directly measuring the diameter between the compensation component 3 and the arc through a measuring component.

[0018] By using this invention, the arc can be measured in real time during the processing, eliminating the need for radius gauges and three-dimensional coordinate instruments; this greatly reduces the difficulty of measuring the actual size of the arc in real time during the processing of part 1, improves the stability and accuracy of arc size measurement, and effectively enhances the product quality and stability of part 1.

[0019] Specifically, the compensation component 3 is telescopically mounted on the tooling body 2 and can move along the radial direction of the arc.

[0020] Among them, a nut is welded on the main body 2 of the tooling, and the compensation component 3 and the nut are connected by threads.

[0021] In practical use, the compensation component 3 has a certain length. After the arc machining measurement of the previous part 1 is completed, the compensation component 3 will be machined by the processing equipment and lose a certain amount. By manually turning the compensation component 3, the operator can move the compensation component 3 along the radial direction of the arc until the compensation component 3 can be processed synchronously with the next arc to be measured. The compensation component 3 can be repeated in multiple arc machining measurements.

[0022] Preferably, the tooling body 2 is detachably mounted on the part 1 by bolts. The tooling body 2 has a through hole for the bolts to pass through. The tooling body 2 is detachably mounted on the part 1 by bolts using the threaded hole on the connector.

[0023] In this embodiment, the tooling body 2 is made of aluminum alloy, which can ensure the strength of the tooling body 2 and reduce its weight.

[0024] Preferably, the measuring component is an inside micrometer.
