Novel workpiece flatness detecting and recording device

Abstract

The invention discloses a novel workpiece flatness detecting and recording device. The device comprises a pedestal and a recording card. A mobile arm and a mobile arm connecting rod are fixedly connected. A moving arm is fixedly provided with a slide block. A transverse screw rod is movably inserted into the mobile arm. A crank is movably installed on a rotation disc. An extrusion spring is located in a probe seat. A probe traverses the probe seat and is extended into a pedestal. A traction groove wheel is fixedly connected to one end of a traction rope. One side of a recording pen seat, whichis far away from the traction rope, is fixedly connected to a traction spring. One side of the traction spring, which is far away from the recording pen seat, is fixedly connected to a pen groove. Arecording pen is movably connected to a recording card. In the invention, an error recording card is set, workpiece errors can be continuously monitored on a large scale, error display is visual, simultaneously, the problems of workpiece damages and inaccurate measurement caused by the mechanical work of an electronic device are effectively avoided, usage is convenient, cost is low and the deviceis suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of precision machinery, in particular to a novel workpiece flatness detection and recording device. Background technique [0002] At present, many processed workpieces are required to have a certain degree of flatness to ensure the safety and accuracy of their use. However, most of the flatness detection devices used today are simple flatness detection rulers. The accuracy is limited, which may lead to large errors, so that the workpiece cannot meet the requirements of use, shorten its service life, and greatly increase the cost. In addition, the cost of most precision machining flatness detection devices is too high, which is not suitable for general use. And it needs very careful maintenance and use, which increases the cost. Therefore, it needs to be improved in order to better detect the flatness of the workpiece. [0003] In order to solve the above-mentioned problems, a deformation detection device wi...

Problems solved by technology

[0004] Although it solves the problem of workpiece flatness detection, the above-mentioned deformation detection device still has obvious defects during use: 1. It uses a variety of electronic components, which are costly and easily damaged, and difficult to maintain in the later stage; 2. . It is impossible to accurately record the unevenness of the workpiece, which is not conducive to the post-processing of the uneven part of the workpiece; 3. The cylinder used cannot accurately control the probe detection distance, which is easy to damage the workpiece and affect the measurement results.
