AI Technical Summary

Technical Problem

In the existing technology, traditional pointer detectors are slow and have deviations when detecting taps. The small contact area between the pin and the tap causes the mounting base to shift, which can easily lead to the pin separating from the tap and falling off.

Method used

A CCD measuring instrument combined with a spring fixing assembly is used. The first and second pins contact the two ends of the tap, and the spring's reaction force is used to fix the tap, which is then used in conjunction with the CCD measuring instrument for testing.

Benefits of technology

It enables rapid and accurate tap testing, avoids shaking and pin falling during the testing process, and improves testing accuracy.

Description

Technical Field

[0001] This utility model belongs to the field of tap measurement technology, and in particular relates to a CCD tap measuring instrument with high accuracy. Background Technology

[0002] A tap is a tool used to machine internal threads. Different types of taps are available for different purposes. To ensure the accuracy of the internal threads, the condition of the tap is checked by a testing device during tap production. This ensures the accuracy of the tap and guarantees that it can accurately machine internal threads.

[0003] Currently, when inspecting taps, traditional pointer-type detectors are often used to slide on the surface of the tap to measure and detect the tap's data. However, this method is often slow and has a certain degree of deviation. In addition, during tap measurement, due to the small contact area between the pin and the tap, when the mounting base is impacted and shifts, the pin can easily separate from the tap and fall off. To solve these problems, there is an urgent need for a CCD tap measuring instrument with high accuracy. Utility Model Content

[0004] The purpose of this invention is to address the problem that current tap testing methods often involve sliding a traditional pointer-type detector on the surface of the tap to measure and detect its data. This method is often slow and prone to errors. Furthermore, during tap measurement, the small contact area between the pin and the tap makes it easy for the pin to separate from the tap and fall off when the mounting base is impacted and shifted. Therefore, this invention proposes a more accurate CCD tap measuring instrument.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a CCD tap measuring instrument with high precision measurement, comprising a worktable, a first mounting seat on the top surface of the worktable, a first pin at one end of the first mounting seat, a mounting frame fixedly connected to the top surface of the worktable, a CCD measuring instrument on the bottom surface of the mounting frame, a second mounting seat on the top surface of the worktable, and sliders on the bottom surfaces of both the first and second mounting seats, the sliders being slidably connected to the worktable through a groove opened in the worktable, and a fixing component inside the second mounting seat.

[0006] As a further description of the above technical solution:

[0007] The fixing component includes a connecting seat, one end of which is fixedly connected to a second mounting rod. A stop is fixedly connected to the outer wall of the second mounting rod, and a spring is provided on the outer wall of the second mounting rod.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the second mounting rod is slidably connected to a sliding sleeve, and a first mounting rod is fixedly connected to one side of the sliding sleeve. One end of the first mounting rod is fixedly connected to a mounting sleeve, and a second pin is fixedly connected inside the mounting sleeve.

[0010] As a further description of the above technical solution:

[0011] The spring is located between the stop block and the sliding sleeve. The mounting sleeve is slidably connected to the second mounting base through a through hole. The connecting seat is fixedly connected to the second mounting base through a through hole. A tap is provided between the second ejector pin and the first ejector pin.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by incorporating a spring, the tap is placed between the first and second ejector pins during use. Simultaneously, by pushing the first and second mounting bases, the first and second ejector pins come into contact with both ends of the tap, thereby fixing the tap. Then, a CCD measuring instrument is used for inspection. This design ensures that when fixing the tap, the spring action keeps the second ejector pin in close contact with one end of the tap, thus preventing the tap from shaking during inspection. Furthermore, the measuring instrument inspection provides a more accurate assessment of the tap's quality compared to traditional pointer-type inspection devices, and allows for faster data detection.
