Multi-axis blade grinding production clamp

Abstract

The invention discloses a multi-axis blade grinding production clamp. The multi-axis blade grinding production clamp comprises a rotating base, an A-axis rotating assembly, a clamp body and a positioning and clamping assembly; the rotating base is used for driving the clamp body to move; the A-axis rotating assembly is arranged on the rotating base and can be driven by the rotating base to move, the A-axis rotating assembly is used for achieving rotation of the clamp body around the A axis, and the A-axis rotating assembly comprises a clamp mounting plate; the clamp body is arranged on the clamp mounting plate and is driven by the A-axis rotating assembly to move, and the clamp body is used for mounting the positioning and clamping assembly and clamping a blade; and the positioning and clamping assembly is arranged on the clamp body and used for clamping and positioning the blade. The multi-axis blade grinding production clamp has the following beneficial effects: six-axis movement control of the clamp can be realized; three rotating shafts are all designed on the clamp; and the clamp can be used for vertical grinding and transverse grinding, the vertical grinding can also be used for grinding left and right reference surfaces, and the clamp can basically correspond to machining forms of various requirements of all blades.

Description

technical field [0001] The invention relates to the technical field of jigs, in particular to a multi-axis blade grinding production jig. Background technique [0002] At present, there are three technical means to make the blade grinding shape in the market: [0003] The first way is to use a 5-6 axis tool grinder to process the blade, so as to shape the blade. The main purpose of this type of machine tool is to process integral tools, such as: integral milling cutters, drills, etc., when using it, design a set of special The fixture is used to clamp the blade, and the fixture is clamped on the equipment chuck, and then the blade is processed. This method is more suitable for the production of more complicated tools, because the 5-6 axis machine tool itself is powerful and the body The space design is also much larger than that of the blade-specific molding equipment, so it can produce a wide range of products. The first method has relatively large limitations, and the co...

Problems solved by technology

The problem with the second method is that the blade needs to be designed in two ways of vertical mounting and flat mounting, which reduces the production range to a certain extent; because it is a 5-axis machining method, there is an angle of freedom that requires the use of inserting Processed in the form of supplementary linkage processing

The above two problems make it possible to process a maximum of 6-7 parts in one-time clamping during blade production. If there are more, two clamping forms must be separated for processing.

However, when one axis must be processed with interpolation linkage, the surface quality of the insert will be inferior to that of the machining part without interpolation linkage, and the accuracy, efficiency, and applicable processing types will be further reduced, so this processing method is still available. There are certain limitations, especially when machining ultra-complex profiled inserts, this phenomenon will be very obvious

[0005] The third method is to divide the different parts of various blades into several processes for processing, and only process 1-2 parts in one-time clamping. This processing method is suitable for blades that are simple to process and require fewer parts to be processed. For forming Complicated blades are not suitable

The problem with the third method is that it is the original form of blade processing, and it is a backward production method. The corresponding slightly more complicated tools will complicate production management. The single production mode makes the corresponding production fixtures and materials very difficult. There are too many intermediate processes, and there are problems such as wasting too much manpower, material resources, and time. At present, this production method is being replaced by other more advanced production methods. In the future, this processing and production method should only exist in super large The special machine for mass production of simple shaped blades has the highest production efficiency, the lowest equipment investment and the lowest unit production cost when there is only one processing state and one processing position and basically no need to adjust the machine again The advantages
