technical field

The invention belongs to the technical field of measuring tool barrels, in particular to a needle roller and roller diameter detector for measuring the outer diameter and roundness of needle rollers and rollers.

Background technique

The outer diameter of the original needle roller and roller is measured using a lever micrometer with an accuracy of 0.001mm. Due to the low measurement accuracy of the lever micrometer in actual measurement, large errors and easy damage during use, the detection of product accuracy cannot be satisfied.

Contents of the invention

The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a needle roller and roller diameter detector which is convenient for detecting the outer diameter of needle rollers and rollers, improves measurement accuracy, and reduces human measurement errors.

The purpose of the present invention is accomplished through the following technical solutions, including a base, a measuring platform, and an instrument. The measuring platform is a concave structure and is fixed on the base; a lifting cylindrical rod is arranged on the inner bottom surface of the measuring platform , the lifting cylindrical rod is covered with a backing bracket, and a measuring backing is provided on the backing bracket; a platform for placing the measured piece is provided on the inner bottom of the measuring platform, and the platform for the measured piece is placed with the measuring backing and the instrument probe. On the same center line; the upper plane of the measuring platform is equipped with a watch barrel, and a watch barrel fine-tuning nut is arranged below the watch barrel, and an instrument is placed in the watch barrel, and the measuring head of the meter is fixed on the meter.

As a preference, the measuring platform is connected with measuring platform fastening screws, the lifting cylinder rod and the backing bracket are fixed by lifting fastening screws, the instrument and the meter cylinder are fixed by instrument fastening screws, and the meter cylinder and the measuring platform are fixed by The table barrel is fixed with fastening screws, and the backing bracket and the measurement backing are fixed by the backing bracket fastening screws.

Preferably, the four corners of the base are respectively provided with angle brackets to keep the instrument parallel.

The beneficial effects of the invention are: it is convenient to detect the outer diameter of the needle roller and the roller, improves the measurement accuracy, reduces the artificial measurement error, and the measurement speed is five times that of the original lever micrometer.

detailed description

The present invention will be described in detail below in conjunction with accompanying drawing: as shown in accompanying drawing 1, the present invention comprises base 2, measuring platform 4, instrument 11, and described measuring platform 4 is a concave structure, and is fixed on the base 2; The inner bottom surface of this measurement platform 4 is provided with a lifting cylindrical rod 7, which is covered with a backing bracket 6, and the backing bracket 6 is provided with a measurement backing 5; There is a measured piece placement platform 16, which is on the same center line as the measurement backer 5 and the instrument probe 14; There is a fine-tuning nut 9 for the watch barrel, and a meter 11 is placed in the watch barrel 10, and the meter measuring head 14 is fixed on the meter 11.

The measuring platform 4 is connected with the measuring platform fastening screw 3, the lifting cylindrical rod 7 and the backing bracket 6 are fixed by the lifting fastening screw 8, the instrument 11 and the table cylinder 10 are fixed by the instrument fastening screw 12, and the table cylinder 10 and the measurement platform 4 are fixed by the table cylinder fastening screw 13, and the backing bracket 6 and the measurement backing 5 are fixed by the backing bracket fastening screw 15.

The four corners of the base 2 are respectively provided with angle brackets 1 for keeping the instrument parallel.

The using method of the present invention is:

1. Before the measurement, according to the outer diameter of the standard part to be tested, the measuring backer 5 is raised above the measuring platform 4 and the measured part is placed on the platform 16, and the lifting fastening screw 8 is tightened;

2. Install the instrument 11 in the watch barrel 10, adjust the measuring platform 4 and the measuring backing 5 so that the measuring platform 4, the measuring backing 5 and the measuring head 14 are on the same center line, and tighten the fastening screw 3 of the measuring platform;

3. Put the measurement backer 5 and the measurement platform 4 close together and concentrically, and then fasten the fastening screws of the backer bracket;

4. Put the measured standard part on the measured part placement platform 16 of the measuring platform 4 and close to the measuring backer 5, the instrument probe 14 is in contact with the measured part, and the instrument 11 is close to the zero position to lock the instrument fastening screw 12 ;

5. Adjust the watch barrel fine-tuning nut 9 so that the meter 11 needle points to the zero position, and lock the watch barrel fastening screw 13;

6. Fine-tune the meter 11 fine-tuning nut. When measuring, the measured standard part is pushed in parallel from the outside to the inside to the measurement backer 5 to make the pointer accuracy of the meter 11 align with the zero position, which is used as a measurement digital line;

7. Remove the standard parts and inspect the product. When the digital line is measured, the difference between the meter 11 pointer and the zero position is the product precision error.

It can be understood that, for those skilled in the art, equivalent replacements or changes to the technical solutions and inventive concept of the present invention shall fall within the protection scope of the appended claims of the present invention.
