Since the birth of the machine tool, fixtures have always been a bottleneck for mechanical processing. Traditional special fixtures have long production preparation time, large maintenance workload, high cost, can not change the use, become an obstacle to the innovation and upgrading of mechanical parts, industrial products replacement.
In the last century, enterprises relied on the introduction of foreign technology to solve the fixture problem. Nowadays, through the innovation of scientific research personnel, the universal machine tool fixture independently developed by China can achieve 'all-in-one'. The aviation industry has heavy scientific research tasks, short production cycle, universal machine tool fixture. Used in military industrial enterprises, it can do more with less to improve machine efficiency, ensure processing quality, reduce production costs, and ensure product delivery.
From dependence on imports to independent research and development
In the 1960s, China introduced the combination of trough and hole system fixtures to solve the problem of long preparation period of fixtures. The trough combination fixtures have low precision and poor rigidity, which can not meet the needs of modern manufacturing. High, rigid, but not flexible. Enterprises using combination fixtures need to be equipped with a trough system and two sets of equipment. It is not only diversified, but also inconvenient to use.
At the beginning of this century, based on the advantages and disadvantages of the groove system and the hole combination fixture, China has developed a blue combination fixture that can be flexibly adjusted and rigidly positioned. However, the groove system, the hole system, and the blue combination fixture exist. A common defect, they are composed of three major systems, eight series, a hundred varieties, a combination of thousands of specifications of fixture components, and require the old technicians with long-term assembly experience to use.
Today, many companies use advanced five-axis machining centers to reduce the number of special fixtures used. Special fixtures have long production cycles, high manufacturing costs, slow response to process speeds, and high tooling storage costs have been qualitatively changed. But five-axis machining The center can only reduce the number of special fixtures used, but can not exclude special fixtures.
Until now, most of the manufacturing industry still uses the traditional special fixture to solve the clamping problem of the workpiece, and the fixture becomes the bottleneck of machining.
'All-in-one' universal machine tool fixture
Beijing Lanxinte Technology Co., Ltd. has many years of experience in the basic research of mechanical manufacturing, and independently developed a universal tool fixture that is 'all-in-one'. It subverts the tradition, breaks the bottleneck of tooling, and is a special fixture that is indispensable in processing. Production preparation time, from a few months to a few minutes, is a revolution in machine tools.
Lanxin special universal machine tool fixture can make shaped parts in a few minutes, regardless of square, round, shaped, long, short, flat, high, short, twisted. All kinds of space angle parts, can Instant response process, all-in-one. Shaped processing, can be completed on the day of the day.
Lan Xinte universal machine tool fixture works:
1, with rigid positioning parts to meet the point, line, surface, hole, arc, circular positioning requirements of the workpiece;
2, using the quick adjustment component to meet the arbitrary length requirements of the three-dimensional size of the workpiece;
3, using the integrated platform to meet the arbitrary spatial angle processing requirements of the workpiece;
4. Using hand, liquid, pneumatic components to quickly clamp the workpiece by squeezing, clamping, and pressing.
Lanxin special universal machine tool fixture linear adjustment accuracy is 0.01mm, repeat positioning accuracy is 0.005mm, angle accuracy is 'second' level adjustment, fixture component and base plate are combined with two pins and one positioning structure, mechanical strength and special fixture Beautiful.
The CNC machine tool modified with Lanxin special universal machine tool can be used not only as a three-axis machining center, but also as a five-axis machining center and an automatic line special machine. It is especially suitable for single-piece manufacturing of research institutes, small batches of military enterprises, and many varieties. Production, but also to meet the needs of mass production.
Lanxin special universal machine tool fixtures, first, completely changed the long manufacturing cycle of special fixtures, slow process response, high maintenance cost, and backward situation in which product transformation can not be reused. Second, the function of changing combination fixtures is insufficient, one-time purchase cost High, large area, must use professional and technical personnel to operate the defects; Third, make up for the five-axis machining center is expensive, solve the inconsistency of tooling fixtures, high cost of use and relatively low-end machine tool technicians.
At present, Lanxin special universal fixture machine tools have also been introduced. The universal fixture machine adopts six-axis three-linkage. Compared with the five-axis machining center, it lacks an infrequently used surface machining capability, and more than one shaped clamping with rigid requirements. Function, but with a sixth axis, the purchase cost is reduced by 1 million.
