Precision machinery parts processing, why need special fixture in precision machining
, the priority is the guarantee of accuracy in the processing, the follow-up is testing process, is also a very important work, unqualified artifacts were detected, would not be out to the customer.
General location of the inspection we are using traditional fixture tools and standards, such as vernier caliper, micrometer, etc.
But some due to a special location, with the traditional detection tools to implement and operation, then it must according to his custom fixture, Xavier precision components co. , LTD. , is committed to precision machining of 15 years, which including custom fixture, customers simply submit drawings, ensure the quality of we can do it.
Like many of our inner circular cylindrical shaft parts processing, shall be carried out on the grinding machine, then positioning is to ensure precision machinery parts processing precision of the first working procedure.
Center hole is not only the positioning precision shaft parts processing and measuring datum, and cooperate with the tailstock top supporting artifacts, guarantee precision machining process benchmark.
Especially when grinding machine for grinding, is there a difference if the top depth of the hole size everywhere, can cause clamped tightly, not to fly out in the process of grinding precision machinery parts, easy to cause safety accidents, thus strengthening the top hole machining process detection is the key to solve this problem.
Adopt the traditional gauge or standard fixture can't satisfy the requirement of the rapid and accurate measurement.
To meet the requirements of precision machining production and testing, according to the technical requirements of the top hole, need to design a kind of special fixture, to finish the test.
According to the above analysis, can be used to compare measuring method using a dedicated fixture to top depth of the hole size.
Gage body is main body parts of fixture design, fixture other precision parts
are through with precision, and its connection with high dimension accuracy requirement.
Gauge design with threaded holes at the top and middle body, dial indicator by locking screws, limit screw ball head rod, prevent slipping and the measuring error caused by the.
Measuring head is the core component of fixture design, the highest precision machining accuracy, not only should cooperate with measured a benchmark, and cooperate with the gauge body precision assembly.
Bar at the top of the measuring head and the dial indicator measuring contact, contact requirements shall not have a central hole, the top surface roughness value is 0.
Fixture parts processing, need to be assembled, and then zero, behind began to measuring precision parts.
