Embodiment 1

[0051] An automatic measuring device for axis degrees of shaft parts, see figure 1 , including a frame 1, a measuring mechanism 2, and a mounting mechanism 3. The measuring mechanism 2 is located above the mounting mechanism 3 , the measuring mechanism 2 is mounted on the vertical mounting surface of the frame 1 , and the mounting mechanism 3 is mounted on the horizontal mounting surface of the frame 1 .

[0052] Among them, see figure 1 The measuring mechanism 2 includes a measuring drive part 21 and a measuring sensing part 22. The measuring driving part 21 is used to drive the measuring sensing part 22 to move vertically up and down. The measuring sensing part 22 is used to contact and measure the workpiece to be measured. The measurement driving part 21 can be selected from a cylinder, and the cylinder can drive the measurement sensing part 22 to move vertically up and down. The measurement sensing part 22 can use a variable air gap inductance micrometer, which adopts a ...

Embodiment 2

[0066] Embodiment two: the difference with embodiment one is:

[0067] see Figure 4 as well as Figure 5 , in the middle position of mounting platform 31, be provided with lifting platform 8, four or more limit rods 9, in the present embodiment, the quantity of limit rods 9 selects 6, and all limit rods 9 ends are hinged on lifting platform 8 Above, the four limit rods 9 are evenly arranged in the circumferential direction on the table surface of the installation platform 31, the hinge axis core line of the limit rods 9 is horizontally arranged, and the swing plane of the limit rods 9 is a vertical plane. The limiting rods 9 can swing to the outside of the lifting platform 8 around their hinge points, and the mounting block 35 can be limited between the two limiting rods 9 .

[0068] see Figure 6 as well as Figure 7 , also includes the installation sleeve 10, the sleeve driving part 11, the shape of the installation sleeve 10 is cylindrical, the middle part of the insta...

Abstract

The invention provides an automatic measuring device for the coaxiality of shaft parts. The device comprises a rack, a measuring mechanism and a mounting mechanism, the measuring mechanism comprises a measuring driving part and a measuring sensing part, the measuring driving part is used for driving the measuring sensing part to vertically move up and down, and the measuring sensing part is used for being in contact with a workpiece to be measured and measuring; the mounting mechanism is positioned below the measuring mechanism; the mounting mechanism comprises a mounting table, a rotary driving part and a feeding part, more than two mounting pieces are arranged at the circumferential position of the mounting table, the mounting pieces are used for mounting workpieces to be measured, the rotary driving part is used for driving the mounting table to horizontally rotate, and the feeding part is used for feeding the workpieces to be measured; and the feeding part is used for driving the mounting table and the rotary driving part to horizontally move front, back, left and right. According to the technical scheme, the overall disassembly and assembly time of the workpiece during working is greatly saved, and the measurement efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of automatic measuring devices, in particular, to an automatic measuring device for axis degrees of shaft parts. Background technique [0002] Parts measurement is the measurement of cylindricity, parallelism, tolerance and other dimensions of mechanical parts. Its measurement accuracy determines whether the machine is good or bad, and is an important link to grasp product quality. The machinery manufacturing industry has always been known as the "heart of industry". Now my country's rapid economic development has an inseparable relationship with the machinery manufacturing industry. With the increasing proportion of machinery manufacturing in industry, machinery manufacturing has become an indispensable strategic industry in my country's economic system. [0003] Existing shaft parts measuring tooling structure such as a Chinese invention patent with publication number CN205783662A is a kind of bearing axi...
