Description

Technical Field

[0001] The utility model relates to the technical field of depth detection tools, in particular to a quick depth detection tool for a flange bottom hole. Background Art

[0002] Sometimes, it is necessary to machine bottom holes on some workpieces, such as through holes and blind holes (i.e., holes that do not penetrate the workpiece). For blind holes, when using some drill bits for machining, due to the structure of the drill bit itself and the requirements of the bolts or other workpieces that need to be connected later, the bottom of the bottom hole is a tapered structure when machining the bottom hole. After machining, the depth of the bottom hole needs to be measured.

[0003] Since the bottom of the bottom hole is a conical structure, traditional detection tools such as latches cannot accurately measure the depth of the bottom hole and cannot quickly determine whether the bottom hole depth meets the standard. Therefore, it is necessary to design a device that can quickly detect the bottom hole depth. Utility Model Content

[0004] The purpose of the utility model is to provide a flange bottom hole depth quick detection tool, which can quickly and efficiently detect whether the bottom hole depth is qualified.

[0005] The embodiments of the present invention are realized through the following technical solutions: the flange bottom hole depth quick detection tool of the present invention includes a sleeve, an annular limiting ring arranged on the side wall of one end of the sleeve, and a push rod threadedly connected to the inner wall of the sleeve; the end of the push rod away from the limiting ring is conical, and the sleeve and the push rod are both inserted into the flange bottom hole.

[0006] Furthermore, a limiting plate is provided on the side wall of the push rod, and the limiting plate abuts against one end of the sleeve provided with a limiting ring.

[0007] Furthermore, a sliding hole is provided on the limiting ring, and a sliding rod is slidably provided in the sliding hole; the axial direction of the sliding rod is parallel to the axial direction of the sleeve.

[0008] Furthermore, a top plate is sleeved on the outer wall of the top rod, and the top plate is fixedly connected to the sliding rod.

[0009] Furthermore, the limiting ring is provided with a plurality of sliding holes distributed in a circumference, one of the sliding holes is provided with a sliding rod, and the plurality of sliding rods are all connected to the top plate.

[0010] Furthermore, a spring is provided between the limiting plate and the top plate.

[0011] Furthermore, a driving ring is threadedly connected to the outer wall of the push rod; and the driving ring abuts against a side of the top plate away from the limiting plate.

[0012] Furthermore, a scale is provided on the outer wall of the push rod near the drive ring.

[0013] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects: the flange bottom hole depth quick detection device of the present invention, when in use, selects a sleeve of appropriate outer diameter according to the diameter of the flange bottom hole, then threadedly connects the sleeve to the push rod, and finally directly inserts the sleeve and the push rod into the flange bottom hole, so that the tapered end of the push rod can be well inserted into the tapered hole at the bottom of the flange bottom hole, and then observes the gap between the limit ring and the flange end face. If there is a gap and the gap is within a certain range, it proves that the flange depth meets the standard (the depth of the bottom hole is within a certain range). If the limit ring is attached to the flange end face, it indicates that the depth of the bottom hole is too deep. If the gap between the limit ring and the flange end face is too large, the depth of the bottom hole is insufficient. Therefore, the depth of the flange bottom hole can be detected quickly and efficiently by this device. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example

[0026] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 4As shown, the quick depth detection fixture of the bottom hole 12 of the flange 11 of this embodiment includes a sleeve 21, an annular limiting ring 22 provided on the side wall of one end of the sleeve 21, and a push rod 23 threadedly connected to the inner wall of the sleeve 21; the end of the push rod 23 away from the limiting ring 22 is conical, and the sleeve 21 and the push rod 23 are both inserted into the bottom hole 12 of the flange 11. Specifically, when in use, a sleeve 21 of a suitable outer diameter is selected according to the diameter of the bottom hole 12 of the flange 11, and then the sleeve 21 is threadedly connected to the push rod 23. Finally, the sleeve 21 and the push rod 23 are directly inserted into the bottom hole 12 of the flange 11. The tapered end of the push rod 23 can be well inserted into the tapered hole at the bottom of the bottom hole 12 of the flange 11. Then, the gap between the limit ring 22 and the end face of the flange 11 is observed. If there is a gap and the gap is within a certain range, it proves that the depth of the flange 11 meets the standard (the depth of the bottom hole 12 is within a certain range). If the limit ring 22 is attached to the end face of the flange 11, it indicates that the depth of the bottom hole 12 is too deep. If the gap between the limit ring 22 and the end face of the flange 11 is too large, the depth of the bottom hole 12 is insufficient. Therefore, the depth of the bottom hole 12 of the flange 11 can be quickly and efficiently detected by this device.

[0027] In this embodiment, a limit plate 24 is provided on the side wall of the push rod 23, and the limit plate 24 abuts against one end of the sleeve 21 provided with a limit ring 22. Specifically, the limit plate 24 can limit the relative position of the sleeve 21 and the push rod 23, preventing the push rod 23 from exceeding the limit when connecting the sleeve 21.

[0028] In this embodiment, the retaining ring 22 is provided with a sliding hole 25, into which a sliding rod 26 slides; the axial direction of the sliding rod 26 is parallel to the axial direction of the sleeve 21. A top plate 27 is sleeved on the outer wall of the top rod 23, and the top plate 27 is fixedly connected to the sliding rod 26. The retaining ring 22 is provided with a plurality of sliding holes 25 distributed circumferentially, each of which is provided with a sliding rod 26, and the plurality of sliding rods 26 are connected to the top plate 27. Specifically, if the gap between the end face of the flange 11 and the limit ring 22 is too large, it indicates that the depth of the bottom hole 12 of the flange 11 is not enough. You can choose to deepen the bottom hole 12. At this time, you can insert the slide rod 26 into the slide hole 25, and make the slide rod 26 abut against the end face of the flange 11. Then you can make a mark on the slide rod 26. After taking it out, you can calculate the depth of the bottom hole 12 of the flange 11 that needs to be deepened by the mark on the slide rod 26, and then make the corresponding deepening depth mark on the flange 11. There is no need to re-measure the depth during subsequent processing.

[0029] In this embodiment, a spring 28 is provided between the limit plate 24 and the top plate 27. A drive ring 29 is threadedly connected to the outer wall of the top rod 23; the drive ring 29 abuts the side of the top plate 27 away from the limit plate 24. A scale 210 is provided on the outer wall of the top rod 23 near the drive ring 29. Specifically, by rotating the drive ring 29, the drive ring 29 compresses the top plate 27, which in turn compresses the slide rod 26. The reading can then be read directly from the scale 210 on the outer wall of the top rod 23, eliminating the need to mark the slide rod 26, making operation more convenient.

[0030] In summary, the flange 11 bottom hole 12 depth quick detection device of this embodiment, when in use, select a sleeve 21 of appropriate outer diameter according to the diameter of the flange 11 bottom hole 12, then thread the sleeve 21 with the push rod 23, and finally insert the sleeve 21 and the push rod 23 directly into the flange 11 bottom hole 12, the tapered end of the push rod 23 can be well inserted into the tapered hole at the bottom of the flange 11 bottom hole 12, and then observe the gap between the limit ring 22 and the end face of the flange 11. If there is a gap and the gap is within a certain range, it proves that the depth of the flange 11 meets the standard (the depth of the bottom hole 12 is within a certain range). If the limit ring 22 is attached to the end face of the flange 11, it indicates that the depth of the bottom hole 12 is too deep. If the gap between the limit ring 22 and the end face of the flange 11 is too large, the depth of the bottom hole 12 is not enough. Therefore, the depth of the bottom hole 12 of the flange 11 can be quickly and efficiently detected by this device.

[0031] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
