Aligning and leveling worktable for measuring cylindricity of slewing type workpiece

Abstract

The invention provides an aligning and leveling worktable for measuring the cylindricity of a slewing type workpiece. The aligning and leveling worktable is composed of an aligning knob (1), an aligning supporting seat (2), an aligning sliding block (3), an aligning tension spring (4), an aligning fixed supporting seat (5), a bearing (6), an outer cover (7), a fixed steel ball (8), leveling knobs(9), a leveling knob supporting seat (10), an inclined block (11), a leveling tension spring (12), leveling steel balls (13), a leveling fixed supporting seat (14), a connecting ring (15), a base (16), a worktable (17) and a vertical tension spring (18). The leveling steel balls are movable supporting points, and the fixed steel ball is a fixed supporting point. The two leveling knobs are adjusted to lead the worktable to realize the leveling function under the support of the two leveling steel balls and the fixed steel ball. When the aligning knob is adjusted, the connecting ring drives the worktable to precisely move along two vertical directions under the action of the aligning tension spring so as to realize the aligning function of the worktable. The structure of the aligning and leveling worktable is simple and practical.

Description

technical field [0001] The invention belongs to the technical field of measurement, and in particular relates to a self-aligning and leveling workbench for measuring the cylindricity of a rotary workpiece. Background technique [0002] The machinery industry has achieved 0.001μm feed technology and 0.005μm machining accuracy, and requires detection technology to adapt to it. It is of great social significance to develop high-precision cylindricity measuring instruments to meet the requirements of advanced manufacturing technology. [0003] At present, there are two kinds of adjustment tables used in cylindricity measuring instruments in the domestic and foreign markets: electric automatic adjustment and manual adjustment. At present, only the British Taylor company adopts the electric automatic adjustment method in the world, which is easy to adjust and has a high degree of automation. However, the structure is complicated, the installation and debugging are troublesome, the...

Problems solved by technology

At present, only the British Taylor company adopts the electric automatic adjustment method in the world. It is easy to adjust and has a high degree of automation. However, the structure is complicated, the installation and debugging are troublesome, the maintenance is cumbersome, and the cost is high, so it is not suitable for the domestic market.

In China, manual adjustment workbenches are generally used, but the adjustment workbenches currently used in the domestic market are designed as a two-layer structure for leveling and alignment, which has a large weight and height, and has a great impact on the measurement results when measuring cylindricity
