Description

Threaded ring

This invention relates to a threaded ring gauge, and more particularly to a threaded ring gauge that can be used to reduce the inner diameter of the inner measuring surface.

The conventional thread ring gauge is used to measure the thread of the screw or the screw according to the measuring thread of the inner measuring surface of the ring gauge body. Therefore, the precision of the thread ring gauge is extremely high, and the thread ring gauge is within the conventional thread ring gauge. The inner diameter of the measuring surface is divided into a fixed size mode and the inner diameter of the inner measuring surface can be reduced.

Wherein the screw ring gauge of the fixed size mode is a tapping thread of a predetermined size by a body, and the thread measuring ring of the fixed size manner cannot be changed within the fixed threading gauge, therefore, the inner threading gauge The thread and inner diameter of the measuring surface may wear due to long-term use, resulting in the inner diameter of the thread ring gauge becoming large and cannot be used continuously.

In addition, the thread ring gauge which can reduce the inner diameter of the inner measuring surface is, for example, the "thread ring gauge with flush pin" patent of U.S. Patent No. 1,447,448. The conventional thread ring gauge includes an adjustable fracture body and a sleeve, the fracture body having an inner measurement surface for contacting the object to be tested, the sleeve being disposed and tightly coupled to the sleeve a second hole in the two ends of the fracture body to avoid relative lateral movement of the hole, the thread ring gauge further comprising a device aligned with the sleeve, and the device partially extends into the sleeve for separation or pulling Near the ends of the fracture body.

In the above-mentioned conventional thread ring gauge, it is usually necessary to first adjust the inner diameter of the measuring surface within the body of the thread ring gauge by adjusting the adjusting screw until the inner diameter of the measuring surface of the thread ring gauge body is in accordance with the desired measurement. After the size, the crack is further filled with wax, and the solidified wax is used to determine the adjusting screw at a predetermined position. When the cured wax is cracked, the inner measuring surface of the thread ring body can be determined. The inner diameter is not a predetermined size, so the inner diameter of the measuring surface within the body of the thread ring gauge must be recalibrated.

Since the cured wax is extremely fragile, or the crack of the cured wax is caused by collision, drop, temperature change, the inner diameter of the measuring surface of the thread ring body must be recalibrated, otherwise the screw produced, The screw has the same specifications.

In general, the conventional fixed-size thread ring gauge has a limited service life, and the cost of the thread ring gauge is relatively high compared to the fixed size method. The thread ring gauge which can reduce the inner diameter of the inner surface of the measuring surface is extremely fragile due to the fact that the curing wax for determining the inner diameter of the measuring surface of the thread ring gauge is extremely fragile, resulting in cracking of the curing wax. At that time, it is necessary to correct and confirm the inner diameter of the measuring surface inside the body of the thread ring gauge. Moreover, since the tolerance of the inner diameter of the measuring surface of the thread ring gauge body is extremely small, usually about 8 μ, the adjustment has difficulty and is not easy. For the above reasons, it is necessary to further improve the above-described conventional thread ring gauge.

The present invention provides a threaded ring gauge, the main purpose of which is to facilitate the correction of the inner diameter of the measuring surface of the threaded ring gauge body.

A second object of the present invention is to fix the inner diameter of the measuring surface within the thread ring gauge to a corrected size.

In still another object of the present invention, the inner diameter of the measuring surface within the thread ring gauge can be repeatedly corrected so that the thread ring gauge has a long service life to reduce the cost of using the thread ring gauge.

A further object of the invention is to avoid axial displacement of the two ends of the threaded ring gauge.

In order to achieve the foregoing object, the technical means and the functions that can be achieved by the technical method include: a body, at least one adjusting component, at least one positioning slot and a gauge. The system is provided with an inner annular surface and an outer annular surface. The inner annular surface is provided with a thread for contact detection of the object to be tested, and a crack exists between the inner annular surface and the outer annular surface to form a first region of the body. a block and a second block, wherein the two blocks form the crack by the end surface, the first block has at least one first hole, and the second block has at least a second hole, the first and the first The two holes are located on the same axis and penetrate the end surface of the two blocks, and at least one hole penetrates the outer ring surface; the at least one adjusting element is disposed in the first hole and the second hole, and is used for separating or Pulling the two ends of the crack body and fixing them; at least one positioning groove is disposed at at least one end of the two ends of the body, and extends toward the outer ring surface to form an opening; the block gauge is placed Inside the positioning slot. Therefore, the present invention can conveniently correct the inner diameter of the measuring surface of the ring body and fix the inner diameter of the inner measuring surface, and the ring gauge can repeatedly correct the inner measuring surface. The diameter of the ring gauge has a long service life to reduce the cost of using the ring gauge, and the positioning groove of the present invention can further avoid axial displacement of the first block and the second block of the ring gauge. .

The inner diameter (D) of the measurement surface can be formed within a predetermined specification. When the inner ring surface 13 of the body 1 is worn due to wear, the inner diameter of the inner measuring surface becomes large (D1) does not meet the predetermined specification (D), the embodiment can still rotate the block gauge 4b horizontally by 90°. Therefore, the two parallel sides forming the second pitch B2 are firmly clamped by the two end faces of the first block 11 and the second block 12, respectively, and the inner ring surface 13 of the body 1 can be determined to be a set. The inner diameter D of the surface was measured.

Referring to FIG. 10, it is a thread ring gauge according to a fourth embodiment of the present invention. In this embodiment, the components of the thread ring gauge are substantially the same as those of the first embodiment, and details are not described herein again.

Referring to FIG. 11 again, the cross section (rectangular section) of the block gauge 4c includes three sets of parallel opposite sides, and the first set of spaced apart C1 and the second spacing are formed between the three sets of parallel opposite sides. C2 and the third pitch C3. For example, the size of the first pitch C1 is greater than the second pitch C2, and the size of the second pitch C2 is greater than the third pitch C3. In addition, as shown in FIG. 10, the three sets of parallel opposite sides of the positioning groove 3c are the same as the first first pitch C1. Thus, the two parallel sides of the first block 11 and the second block 12 are firmly clamped by the two parallel sides having the first first pitch C1, so that the inner ring surface 13 of the body 1 is firstly held. The inner diameter (D) of the measurement surface can be formed within a predetermined specification. When the inner ring surface 13 of the body 1 is worn due to wear, the inner diameter of the inner measuring surface becomes large (D1) does not meet the predetermined specification (D), the embodiment can still rotate the block gauge 4c horizontally by a predetermined angle. So that the two parallel sides forming the second pitch C2 are firmly clamped by the two end faces of the first block 11 and the second block 12, respectively, and the inner ring surface 13 of the body 1 can be determined to be a setting. The inner diameter D of the surface is measured. And the two parallel sides forming the third pitch C3 are firmly clamped by the two end faces of the first block 11 and the second block 12, respectively, and the inner ring surface 13 of the body 1 can also be determined. The inner diameter D of the surface is measured.

Referring to Fig. 12, a thread ring gauge according to a fifth embodiment of the present invention, in the present embodiment, the member of the thread ring gauge is substantially the same as that of the first embodiment, and details are not described herein again. In this embodiment, only the peripheral wall of the positioning groove 3d and the peripheral surface of the block gauge 4d are formed with a tapered surface, so that the positioning groove 3d and the inclined tapered surface of the block gauge 4d can be in contact with each other, and the inclined cone of the two contacts is simultaneously The threaded portion is screwed to the surface, so that the rotation of the positioning groove 3d by the block gauge 4d and the adjustment of the adjusting member 2 until the block gauge 4d is firmly clamped can also make the inner ring of the body 1 The surface 13 can be restored to the inner diameter D of the measured surface within the original setting.

In summary, the thread ring gauge of the present invention can clamp the block gauges 4a, 4b, 4c and 4d into the positioning grooves 3a, 3b, 3c and 3d, so that the thread ring gauge of the present invention can be worn due to wear. When the inner diameter of the inner measuring surface becomes large (D1) does not meet the predetermined specification (D), the inner annular surface 13 of the body 1 can be quickly and conveniently adjusted to a set measuring inner diameter (D). Moreover, when the block gauges 4a, 4b, 4c, and 4d correspond to the shape of the receiving groove formed by the positioning grooves 3a, 3b, 3c, and 3d, the thread ring gauge of the present invention can also avoid the body 1 The first block 11 and the second block 12 produce an axial offset. In addition, when the columnar cross-section of the block gauges 4b, 4c includes an array of parallel opposite sides, the pair of sides of the array can be designed as an array of equidistant decreasing distances, or by the hole wall of the positioning groove 3d. When the circumferential surface of the block gauge 4d is formed with a tapered surface and the threaded portion is screwed, the rotation of the positioning groove 3d by the block gauge 4d can also be used to achieve the rotation of the same block gauge 4d. The thread ring gauge of the present invention can effectively increase the usability.
