Description

A shoe last measuring instrument

technical field

The utility model relates to the technical field of measuring instruments and measuring equipment, in particular to a shoe last measuring instrument.

Background technique

The shoe last is the forming mold of the shoe, also called the shoe mold; the shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits the foot and whether it can protect the foot.

Since the shoe last is an irregular geometric shape and mainly curved, it cannot be measured accurately with general measuring tools. At present, the commonly used measurement method is to fix the shoe last on the plasticine and measure it with a micrometer, vernier caliper, triangle ruler, cloth tape ruler, etc. However, the support of the shoe last is unstable, the measurement data is not accurate enough and the operation is difficult.

At present, due to the lack of an accurate positioning system, the three-dimensional detection device cannot be used for the standard measurement of the shoe last, and because of the lack of database support, the designed shoe last can only be made according to the designer's personal feeling. The size, shape curve, and straightness of the shoe last lack classification inspection standards, making it difficult to control the quality of the shoe last.

At present, there is still a lack of an effective measuring instrument and measuring method when testing batches of shoe lasts. At present, the traditional measurement method is still used for the detection of batches of finished shoe lasts, that is, various micrometers, calipers and other measuring rulers are used for measurement, and the traditional measurement method is used to measure batches of finished shoe lasts. The problem lies in: first, the measurement efficiency is low, which seriously restricts the efficiency of shoe last production; second, the quality of the finished shoe last after measurement is uneven, due to the limitation of measurement conditions, measurement standards and human factors, the same batch of finished products In the shoe last, the quality of the finished shoe last that has passed the test (the shape curve of the shoe last, the straightness, the front height of the shoe last, and the height of the last last) will be greatly different due to different factors, and the consistency of the finished shoe last is different. Third, for complex shoe lasts, existing measurement methods cannot meet the measurement requirements, and some parameters of shoe lasts cannot be measured.

At the same time, in order to meet the needs of three-dimensional measurement of irregular objects, an automatic image measuring instrument (also known as image probe coordinate measuring machine) is designed. This automatic image measuring instrument can meet the requirements of each parameter point of the finished shoe last. The requirements of precise measurement can also match the requirements of batch measurement, the measurement efficiency is high, and the consistency of the molded shoe last measurement is high. However, for the automatic image measuring instrument, its shortcomings are: First, the automatic image measuring instrument The cost is relatively expensive, ranging from hundreds of thousands to millions or tens of millions. The use of automatic image measuring instruments for measurement will inevitably increase the cost of production equipment; The pre-processing before the measurement of the shoe last has high requirements, and the use and applicable measurement range of the automatic image measuring instrument are limited.

Therefore, there is an urgent need for a shoe last measuring instrument that can measure and detect shoe lasts and is easy to use.
