1、Milling fixture design features First, the main types of milling machine fixture and structure of the form Milling fixture for machining parts on the main plane, groove, keyway, spline, and the gap as well as face shape. Usually as a result of milling fixture table together with the feed movement, i
2、n different ways according to the feed milling fixture can be divided into straight-line feed type, feed circular mode and rely on three types of feed-type. 1. Linear feed-type milling fixture This type of milling machine with the most. Fixture installed in the milling machine table, the processing
3、in a straight line with the feed table by way of movement. According to the workpiece quality, structure and production quantities will be designed as a one-piece fixture points more than the parallel and more than a row followed by clamping of the linkage approach, sometimes the use of sub-degree i
4、nstitutions, both to improve production efficiency. 2. Circle-type milling machine fixture feed Circle feed milling in the case of non-stop loading and unloading the workpiece, the general is a multi-tasking, and in the milling machine rotary table use. This fixture is compact and easy to operate, m
5、obile time and auxiliary time overlap is high-performance milling fixture, for use in high-volume production. 3. By mold milling fixture This module depends on the milling machine with a fixture used in dedicated or universal milling machines on the processing of various non-circular surface. On the
6、 role of mold is to make access to supplementary motor workpiece to form a profile campaign. Movement by way of the main feed through mode can be divided into straight-line milling machine fixture and circle into the feed to the two. Second, the design features of milling fixture As a result of mill
7、ing and cutting force cutting more and more intermittent cutting edge, easy processing of vibration, so they should pay attention to the design of milling machine fixture: clamping force to be sufficient self-locking and anti-stroke; fixture installation to be accurate and reliable , that is, when t
8、he processing installation and the proper use of directional keys on the knife device; specific folder have sufficient stiffness and stability, the structure must be reasonable. As a result of milling and cutting force cutting more and more intermittent cutting edge, easy processing of vibration, so
9、 they should pay attention to the design of milling machine fixture: clamping force to be sufficient self-locking and anti-stroke; fixture installation to be accurate and reliable , that is, when the processing installation and the proper use of directional keys on the knife device; specific folder
10、have sufficient stiffness and stability, the structure must be reasonable. 1. Directional keys Directional key position, also known as keys, installed on the bottom of the vertical slot fixture, generally with two, an in a straight line, the farther the distance, the higher the precision-oriented, w
11、ith screw fastening in the specific folder. Directional keys work with the milling machine with table-shaped slot in the machine tool fixture to determine the correct position; can absorb part of the cutting torque, reducing the load on clamping bolt to increase the stability of the fixture, so flat
12、 and some special drilling jig boring machine fixture is also frequently used. Directional keys are rectangular and round two. 2. Of the knife device Devices on the knife block and knife by the side of the foot of the fixture and tool used to determine the relative position. The structure of the for
13、m of a knife depends on the shape of the surface processing. Directional high-precision fixture should not be used or heavy directional keys, but in the specific folder on one elongated side processing as a base to look for is the installation location calibration fixture.Knife block on the pin and
14、screw fastener commonly used in the specific folder, its location should be easy-to-use plug-foot on the knife, without prejudice to the workpiece loading and unloading. On the knife when the knife cutter block with a plug in between the feet with the knife tool to avoid direct contact block or caus
15、e damage to the knife blade block premature wear. Cypriot Cypriot feet are flat feet and two-foot cylindrical plug, the thickness and diameter of 3 5mm, manufacturing tolerance h6. Side of the knife block and feet have been standardized (the design can be found in the relevant manual), use the total
16、 fixture Sedat map scale should be marked on the knife block size and the work surface and positioning the location between the components. Devices should be installed on the blade of the knife and is easy to cut one end of the workpiece. 3. Folder specific design To improve the milling fixture installed in the machine tool stability, reduce its intermittent cutting may be caused by vibration, not only in the specific folder have sufficient stiffne
