Abstract
Description
Technical Field
[0001] The utility model relates to a tooling fixture for adjusting and measuring the size of a ring groove, and belongs to the technical field of mechanical processing and manufacturing. Background Art
[0002] The existing ring groove size and symmetry measurements are all completed by three-dimensional coordinate measuring machines, especially for V-grooves, which cannot be measured by ordinary rulers. However, for large-scale production, the size and symmetry of the ring groove of each part must be measured by a three-dimensional coordinate measuring machine, which is time-consuming, inefficient and costly. Summary of the Invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tooling fixture for adjusting and measuring the size of a ring groove.
[0004] A tooling fixture for adjusting and measuring the size of a ring groove, wherein a support block is connected to a base plate via a thread, the base plate has a through hole, and a workpiece to be measured is installed in the through hole of the base plate, a first positioning block is connected to a tooling body via two first bolts, the first positioning block has a through hole, a first top screw is used to connect the dial rod of a first detection meter to the first through hole, and a needle contact of the first detection meter contacts the workpiece to be measured, a second positioning block is connected to the tooling body via two second bolts, the second positioning block has a through hole, a second top screw is used to connect the dial rod of a second detection meter to the second through hole, and a needle contact of the second detection meter contacts the workpiece to be measured.
[0005] The tool body is placed on the base plate, and the V-groove of the tool body contacts the workpiece to be measured.
[0006] The present invention uses the standard ring groove as a benchmark and simplifies the measurement of the ring groove. It is aimed at parts with similar ring grooves. Since the "ring groove" type part is an annular cylinder with two inclined surface structures, the V-shaped ring groove symmetry accuracy and inclined surface angle accuracy are very high, and the production batch is large (for example, the tool handle has an annual output of more than 30,000 pieces).
[0007] The utility model selects a rectangular body as the basic body. When installing, it is only necessary to fit the bottom surface to the reference surface of the base plate, fit the V-groove to the outer circle of the measured part, and read the pointer reading of the measuring meter. The utility model well solves the principle of unified reference, fast installation and alignment, stable quality and high efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

It should be further understood that the term "comprising" used in the specification of the present utility model refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof. It should be understood that when an element or component is said to be "connected" to another element or component, it may be directly connected to the other element or component, or there may be intermediate elements or components. The term "and / or" used herein includes any unit and all combinations of one or more associated listed items.
[0014] Those skilled in the art will understand that unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art.
[0015] Example 1: Figure 1 、 Figure 2 As shown, a tooling fixture for adjusting and measuring the size of an annular groove, the tooling body 4 has a V-shaped groove, the tooling body 4 is placed on the base plate 1, the support block 2 is connected to the base plate 1 by a thread, the base plate 1 has a through hole, the workpiece 3 to be measured is installed in the through hole of the base plate 1, the first positioning block 5 is connected to the tooling body 4 by two first bolts 7, the first positioning block 5 has a through hole, the meter rod of the first detection meter 12 is connected to the first through hole by the first top screw 11, the meter needle contact of the first detection meter 12 contacts the workpiece 3 to be measured, the second positioning block 13 is connected to the tooling body 4 by two second bolts 14, the second positioning block 5 has a through hole, the meter rod of the second detection meter 6 is connected to the second through hole by the second top screw 8, the meter needle contact of the second detection meter 6 contacts the workpiece 3 to be measured, and the V-shaped groove of the tooling body 4 contacts the workpiece 3 to be measured.
[0016] Example 2: Figure 1 、 Figure 2As shown, a fixture for adjusting and measuring the ring groove size is provided. The position of the inspection table that has measured the standard part is fixed, and the workpiece 3 to be measured is directly measured. The ring groove size and symmetry can be quickly judged by the change of the measuring table pointer. It is convenient, fast, accurate and low-cost.
[0017] The positioning block includes a first positioning block 5 and a second positioning block 13. The steps of using the utility model are as follows: install the positioning blocks on the substrate 1 to be measured, install the measuring gauge including the first detection gauge 12 and the second detection gauge 6 on the positioning blocks, and fix them with the top screw, fit the outer circle of the standard part with the V-groove of the tool body 4, adjust the reading of the measuring gauge to 0, replace the standard part with the workpiece to be measured, fit the outer circle of the workpiece to be measured with the V-groove of the tool body 4, read the reading of the measuring gauge, and judge the size and symmetry of the ring groove. If the pointer rotates in the positive direction, it means that the size of the ring groove is reduced, otherwise, the size of the ring groove is increased. If the readings of the two measuring gauges are inconsistent, if the reading of the upper groove surface is greater than the reading of the lower groove surface, the position of the ring groove is offset downward, otherwise, it is offset upward.
[0018] Example 3: Figure 1 、 Figure 2 As shown, the tooling body has a conical surface or a V-shaped opening. The standard part is placed in the hole of the substrate. Two measuring pointer gauges are installed on the positioning block. The positioning block is installed on the measuring plate. The conical surface or V-shaped opening of the measuring plate fits the outer circle of the standard part. The first inspection gauge 12 measures the top of the V-groove of the standard part and the second inspection gauge 6 measures the bottom of the V-groove of the standard part. The pointer gauges of the first inspection gauge 12 and the second inspection gauge 6 are adjusted to 0.
[0019] Place the part to be measured into the hole, aligning the V-shaped opening of the measuring plate with the outer diameter of the part. Read the dial gauge reading. This allows for easy measurement of the symmetry of the circular V-groove of the part to be measured. It also allows for quick calculation of the remaining machining allowance, facilitating calculation of allowance during roughing and dimensions during finishing. This system is suitable for high-volume part production and offers low-cost performance.
[0020] As described above, the embodiments of the present invention have been described in detail. However, it is obvious to those skilled in the art that many variations are possible without departing from the inventive concept and effects of the present invention. Therefore, all such variations are included within the scope of protection of the present invention.
