Three-dimensional measuring machine for the shoe mould

Abstract

The invention discloses a three-dimensional measuring machine of shoe die, which is characterized by the following: comprising surveying work assembling system, feeding control system, mechanical motor system and controlling PC machine; arranging the surveying work assembling system on the work bench of the mechanical motor system to fix the sample shoe; controlling the feeding direction of three axis movement and speed with the feeding control system; adjusting the measuring time-effect and accuracy; touching the sample shoe with the metering needle of needle measuring head on the mechanical control system; collecting coordinate on the surface of the sample shoe; sending a impulse signal to digital display meter at the time of touching the sample; receiving the impulse signal with digital display meter; recording; sending to the controlling PC machine; deacidizing a same three-dimensional die of the sample shoe with the inverting software on the controlling PC machine.

Description

Technical field: [0001] The invention relates to a three-dimensional measuring machine, in particular to a three-dimensional measuring machine for shoe molds and a measuring method. Background technique: [0002] We know that sports shoes are one of the essential daily necessities in every country, and it is also a pillar industry in the economically developed southeast coastal areas of our country, which can earn hundreds of millions of foreign exchange for our country every year. Shoe molds are an important piece of equipment in the shoe industry. The mold quality, production cycle, and cost are directly related to the production efficiency of sports shoes, the speed of new product sample opening, and the market competitiveness of product price performance. Our country is already a big country of shoe industry production now, but not a big country of technology. The production technology and process of shoe molds need to be improved urgently, especially in the past ten ye...

Problems solved by technology

[0006] Production practice has proved that this production method is suitable for some daily necessities\mechanical products with relatively simple appearance and structure, but it is used to deal with round and extremely irregular sole samples. The disadvantages are obvious: 1) Low efficiency, It takes two experienced hands more than two days to sort out a medium-difficulty 2D map, and it takes about seven days to construct a 3D model

The delivery cycle of a mold is only more than 20 days, including the time of mold trial and mold modification, because most of the cutting processes cannot greatly shorten the processing time under the current machine tool technology conditions, so under the same process, it can be Greatly improving the efficiency of three-dimensional input is equivalent to shortening the molding cycle of the mold; 2) almost all the sample soles are soft materials, and the shape changes continuously during the scanning measurement, so it is impossible to determine a suitable measurement state; When the bottom and surrounding areas are scanned separately, five groups of highly random placements cannot provide accurate correction benchmarks for the subsequent 2D image file arrangement; 3) Low modeling accuracy: 2D image arrangement is mainly based on photos and card boards Scanning is the main method, and there are many discrepancies with the sample to be tested, up to a few millimeters; because the pattern at the R corner where the outsole and the side meet cannot be normally handed over when drawing a 2D picture, the number of sections is insufficient and the position cannot be adjusted accurately. When it is necessary to adjust visually, it is seriously distorted. It is necessary to continue to adjust the shape after trial processing of the 3D model, and it must be repeated several times.

4) There is a strong dependence on the experience and technical level of designers. Among the labor costs of shoe mold production, design costs have always been high, accounting for more than 1 / 3

In addition, in order to shorten the mold-making timeliness and ensure the delivery time, the 3D designers who spend the longest timeliness need to work overtime or even overnight, which consumes a lot of physical energy

Leading to a high turnover rate of high-quality professionals, affecting the smooth development of the entire industry

5) The cost of trial processing is high

To achieve the accuracy of each 3D model within the range accepted by customers, it takes more than 20 hours of CNC trial cutting time. If there are multiple shoe models being developed in the mold factory at the same time, it will take up a lot of CNC resources, and this part It is a great waste that a portion of resources are not directly used in production and processing
