Description

Technical Field

[0001] The utility model relates to the technical field of reaming depth detection, in particular to a measuring tool for quickly detecting the effective depth of reaming. Background Art

[0002] Reaming is a process whereby a reamer removes a small amount of metal from the workpiece hole wall to improve dimensional accuracy and surface quality. Reaming is a widely used finishing method for holes and is a more economical and practical method for smaller holes compared to internal grinding and fine boring.

[0003] When processing a reaming process, the tolerance of the reaming depth is strictly required. Currently, the reaming depth is detected using a digital caliper to detect the effective reaming depth. However, the detection accuracy is low, which also causes the operator to repeatedly detect and modify the reaming depth.

[0004] Therefore, the present application proposes a rapid detection tool for the effective depth of reaming to solve the above problems. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a rapid detection of reaming effective depth gauge, which can realize rapid detection of reaming effective depth and save the operator's time of repeated corrections due to inaccurate detection of reaming effective depth.

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] A quick-detection reaming effective depth gauge, characterized in that it comprises a shell, an inner core, a locking mechanism, a spring, and a dial indicator. The upper end of the shell is provided with a movable groove, the notch of the movable groove is connected to the dial indicator through the locking mechanism, the testing end of the dial indicator extends into the movable groove of the shell and contacts the inner core inserted into the mounting groove provided on the shell, and a spring is provided between the top end of the inner core and the lower end of the locking mechanism.

[0008] The locking mechanism is a self-locking nut, the lower end of which is threadedly connected to the notch of the movable groove of the housing, and the locking hole on the self-locking nut is connected to the test end of the dial indicator.

[0009] The inner core consists of a vertical rod and an upper plate. The top of the vertical rod is connected to the upper plate as a whole. The diameter of the upper plate is larger than the diameter of the vertical rod. The upper plate is located in the movable groove. The vertical rod is connected to the installation groove. A spring is provided between the upper plate and the self-locking nut.

[0010] Specifically, the spring is located outside the test end of the dial indicator.

[0011] Specifically, the lower end of the vertical rod extends from the mounting slot of the shell.

[0012] Beneficial effects of the utility model:

[0013] When the utility model detects the effective depth of the reaming hole, the inspection tool is first assembled, wherein the size of the vertical rod of the inner core is set to be consistent with the effective depth size of the reaming hole, and then the bottom of the vertical rod of the inner core is inserted into the reaming hole of the product to be detected, and then the inspection tool is pressed down. When the bottom of the vertical rod moves to a point where it cannot move downward, the upper plate of the inner core will press the dial indicator, and the dial indicator can be used to read the value, that is, the effective depth of the reaming hole at this time is detected, thereby realizing rapid detection of the effective depth of the reaming hole and saving the operator's time for repeated corrections due to inaccurate detection of the effective depth of the reaming hole.

[0014] The utility model can quickly detect and improve the accuracy, reduces the time for selection and rework due to unqualified reaming depth, improves production efficiency, reduces defective rework, and saves labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] Example 1

[0023] As shown in the figure, a movable groove 11 is provided at the upper end of the shell 1, and the notch of the movable groove 11 is threadedly connected to the lower end of the self-locking nut 2, and the locking hole on the self-locking nut 2 is connected to the test end of the dial indicator 3, and the test end of the dial indicator 3 extends into the movable groove 11 of the shell 1 and contacts with the upper plate 42 of the inner core 4 inserted in the mounting groove provided on the shell 1. The inner core 4 is composed of an upper plate 42 and a vertical rod 41 connected as a whole. The inner core 4 has a T-shaped structure as a whole. The diameter of the upper plate 42 is larger than the diameter of the vertical rod 41. The upper plate 42 is located in the movable groove 11, the vertical rod 41 is connected to the mounting groove of the shell 1, and the lower end of the vertical rod 41 extends from the mounting groove of the shell 1. A spring 5 is provided between the upper plate 42 and the self-locking nut 2, and the spring 5 is located on the periphery of the test end of the dial indicator 3.

[0024] It should be noted that a self-locking nut 2 is used to mount the dial indicator 3 on the housing 1. The self-locking nut 2 used is an existing connecting component, so the principle diagram of the self-locking nut and its detailed description are not drawn in detail in this application.

[0025] Example 2

[0026] When using the present invention for inspection, first assemble the inspection fixture designed in this application, wherein the diameter size of the vertical rod 41 of the inner core 4 should be set to be consistent with the diameter size of the effective depth of the reaming hole 101, and then insert the bottom of the vertical rod 41 of the inner core 4 into the reaming hole 101 of the product 100 to be inspected, and then press down the inspection fixture. When the bottom of the vertical rod 41 moves to a point where it cannot move down, the upper plate 42 of the inner core 4 will push the test end of the dial indicator 3, and the reading can be taken by the dial indicator 3, that is, the effective depth of the reaming hole 101 at this time is detected, thereby realizing rapid detection of the effective depth of the reaming hole, saving the operator's time for repeated modifications due to inaccurate detection of the effective depth of the reaming hole; rapid detection and improved accuracy reduce the time for selection and rework due to unqualified reaming depth, thereby improving production efficiency, reducing defective rework, and saving labor costs.

[0027] It should be noted that when the reaming hole 101 is being processed, the diameter of the bottom of the reaming hole 101 will be small, which is smaller than the diameter set for the reaming hole 101 itself. Therefore, the effective depth of detection is to detect the hole depth of the reaming hole 101 according to the diameter size set for it. For example: for example, the diameter of the reaming hole is 8, and the diameter of the bottom of the reaming hole is 6. The effective depth of the reaming hole is to detect the hole depth when the diameter is 8.
