Embodiment 1

[0027] Example 1, see figure 1 , figure 2 with image 3 , a small-volume flexible grinding machine provided in this embodiment, which includes a cylinder body 1, a pneumatic rotor assembly 2, a grinding disc 3, an inner cylinder 4, an outer cylinder 5, a flexible elastic member 6 and an air nozzle 7, and the inner cylinder 4 is fixed Sleeved on the cylinder body 1, the pneumatic rotor assembly 2 is arranged in the inner cavity of the cylinder body 1 to form a pneumatic grinding assembly, and the grinding disc 3 is arranged on the pneumatic rotor assembly 2, and the grinding disc 3 is circular.

[0028] The air nozzle 7 is arranged on the top of the inner cylinder 4, and communicates with the inner cavity of the cylinder body 1 through an air passage. The inlet and outlet air ports 11 are connected, and the top of the cylinder body 1 is provided with a back air passage 12 communicating with the air nozzle 7 corresponding to the position of the air nozzle 7, and the outer wal...

Embodiment 2

[0030] Example 2, see Figure 4 with Figure 5 , a small-volume flexible grinding machine provided in this embodiment, which has basically the same structure as that of Embodiment 1, the difference is that it also includes a rotation-limiting assembly 8, the grinding disc 3 is square, and the rotation-limiting assembly 8 includes a rigid An inner ring 81, a rigid outer ring 82 and a flexible film 83, the rigid inner ring 81 is arranged at the center of the flexible disc and fixed on the grinding disc 3, and the rigid outer ring 82 is arranged on the flexible film 83 and fixed on the inner cylinder 4. Using flexible film 83, the sealing effect is good, and the dustproof effect can be improved.

Embodiment 3

[0031] Example 3, see Image 6 with Figure 7 , a small-volume flexible grinder provided in this embodiment has basically the same structure as that of Embodiment 2, the difference is that the structure of the rotation limiting assembly 8 is different, specifically, the rotation limiting assembly 8 includes a rigid inner ring 81. Rigid outer ring 82 and planar scroll spring 84. The rigid inner ring 81 is arranged at the center of the planar scroll spring 84 and fixed on the grinding disc 3. The rigid outer ring 82 is arranged on a plane The outer edge of the scroll spring 84 is fixed on the inner cylinder 4, and the planar scroll spring 84 is adopted, which has a good rotation-limiting effect and has a longer service life than the flexible film 83 in Example 2.

Abstract

The invention discloses a small-size flexible grinding machine. The small-size flexible grinding machine comprises a cylinder body, a pneumatic rotor assembly arranged in an inner cavity of the cylinder body, a millstone, an inner barrel, an outer barrel, a flexible elastic part and an air tap, wherein the millstone, the inner barrel, the outer barrel, the flexible elastic part and the air tap are arranged on the pneumatic rotor assembly. The small-size flexible grinding machine is reasonable in structural design, a traditional pneumatic grinding machine and a flexible connecting device are ingeniously combined to form an integrated structure, certain axial and radial floating strokes are achieved, the buffering and passive compensation effects are achieved, the millstone is well attached to a complex curved surface in a profiling mode in the grinding process, the consistency of the grinding action force can be well guaranteed, the situation that the millstone is kept its distance from the complex curved surface or the complex curved surface is polished uneven is avoided, the grinding and polishing quality is improved, the overall structure is compact, the overall length is effectively shortened, the occupied space is small, the size is small, matching installation and use with an industrial robot are facilitated, in addition, the air tap is arranged at the top of the inner cylinder so that built-in layout of an air pipeline can be realized, exposure is avoided, and the overall appearance is simple and attractive.

Description

technical field [0001] The invention relates to the technical field of pneumatic grinders, in particular to a small-volume flexible grinder. Background technique [0002] In manufacturing enterprises, product quality and production efficiency are the main factors to improve the competitiveness of enterprises. In order to improve the competitiveness of enterprises, automated production is gradually replacing manual processing. In the process of improving the degree of automation of enterprise production, industrial robots have played a major role in promoting effect. [0003] In order to improve the grinding efficiency of mass-produced castings, reduce production costs, and avoid the harm of metal dust to grinding workers, for mass-produced castings, industrial robots are usually used with grinding tools instead of manual grinding and polishing of burrs. [0004] The traditional way of using grinding tools and industrial robots is mostly rigid connection. The disadvantage of...
