Description

Measuring tools for measuring arc parts

technical field

The invention relates to a measuring tool, in particular to a measuring tool for measuring arc parts.

Background technique

In the production process, we often encounter the problem of measuring the inner diameter of the arc, especially for the arc parts less than 180 degrees. Usually, it cannot be measured with ordinary conventional measuring tools, or the accuracy is low during the measurement process. The size error of the measured arc is very large, and it cannot meet the production needs in severe cases.

Contents of the invention

The technical problem to be solved by the present invention is: when measuring arc parts less than 180 degrees, under normal circumstances, it cannot be measured with ordinary conventional measuring tools, or the accuracy is low during the measurement process, so that the size error of the measured arc is very large. If it is too large, it cannot meet the production needs in severe cases. A measuring tool for measuring arc parts is provided.

In order to overcome the defects existing in the background technology, the technical solution adopted by the present invention to solve its technical problems is: the present invention includes a ring measuring body, and the two ends of the ring measuring body are provided with a dial gauge mount, and the dial gauge A dial indicator is installed on the seat frame, and the cross bar is fixed at both ends of the ring measuring body. A high-precision level is arranged on the cross bar, and the high-precision level is placed in a groove milled on the cross bar. The precision level is connected with a ring part symmetrical adjustment bolt and a ring part horizontal adjustment bolt.

According to another embodiment of the present invention, it further includes that the dial gauge installed on the dial gauge mount is fixed by locking bolts.

According to another embodiment of the present invention, it further includes drilling a small hole in the center of the cross bar to connect the universal bar body.

According to another embodiment of the present invention, it further includes that the universal rod body is connected to the magnetic watch base, and is fixedly connected by bolts.

The beneficial effects of the present invention are: the structure of the present invention is simple and easy to maintain; the structure of the present invention can be made into a series of different measuring ranges; It is convenient, fast and easy to operate. the

Description of drawings

The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

Fig. 1 is a structural representation of the present invention;

Among them: 1. Ring measuring body, 2. Cross bar, 3. Dial gauge mount, 4. High-precision level, 5. Locking bolt, 6. Dial gauge, 7. Magnetic base, 8. Bolt, 9. The universal rod body, 10. The horizontal adjustment bolt of the ring part, and 11. The symmetrical adjustment bolt of the ring part.

Detailed ways

Fig. 1 is the structural representation of the present invention, comprises ring measuring body 1 among the figure, and described ring measuring body 1 two ends are provided with dial gauge mount 3, is installed with dial gauge 6 on dial gauge mount 3 , the crossbar 2 is fixed on the two ends of the ring measuring body 1, the crossbar 2 is provided with a high-precision level 4, and the high-precision level 4 is placed in a groove milled out on the crossbar 2, and the high-precision level 4 is connected with the ring part symmetrical adjustment bolt 11 and the ring part horizontal adjustment bolt 10. The ring measuring body 1 is a 1/4 ring, and the ring measuring body 1 is zero-calibrated through the standard circle with the same ring diameter, so that the dial gauge 6 is compressed to the maximum range, and the pointers of the dial gauge 6 on both sides must be consistent, and then the ring measuring body 1 part is installed on the magnetic table base 7, and the magnetic table base 7 is adsorbed at a suitable position of the measuring part. Roughly adjust the horizontal direction, then swing left and right, look at the dial gauge 6 on one side for fine adjustment and fixed level, then rotate the ring part of the device to make the pointers of the dial gauge 6 on both sides consistent, read out the gauge value, and compare it with the pre-calculated The table of the swing of the dial indicator and the change of the radius function of the circle where the arc is located can be used to obtain the radius of the arc at this time.

The dial gauge 6 installed on the dial gauge mount 3 is fixed by the locking bolt 5 . Dial gauge 6 can fine-tune the level and fix the level.

A hole is drilled in the center of the cross bar 2 to connect the universal rod body 9 . The universal rod body 9 is used to connect the magnetic table base 7 .

The universal rod body 9 is connected with the magnetic watch base 7 and is fixedly connected by bolts 8 . The magnetic table base 9 can be placed in each suitable position of the parts during work.

The structure of the present invention is simple and easy to maintain. The structure of the present invention can be made into a series of different measuring ranges. The measuring range can cover all arc parts from 50mm and above and less than 180 degrees. It is convenient and fast to measure the arc, and the actual operation Simple.
