Multifunctional milling fixture and milling machine using multifunctional milling fixture

Abstract

The invention provides a multifunctional milling fixture and a milling machine using the functional milling fixture. The milling fixture consists of a fixing part, a clamping part connected with one end of the fixing part and a screw rod screwed on the clamping part, wherein the fixing part is cylindrical and is provided with a connecting surface formed by a circumferential surface; the clamping part is shaped as a long strip and is provided with a jointing surface and an open surface which are located at the two ends of a longitudinal length direction, and a clamping surface and a locking surface which are located between the jointing surface and the open surface and are adjoined, wherein the jointing surface is fit and connected with the connecting surface, the clamping surface is depressed along the length direction of the clamping part to form a clamping groove, the upper part of the clamping groove is wide and the lower part of the clamping groove is narrow; the part, penetrating through the locking surface, of the screw rod stretches into the clamping groove. The multifunctional milling fixture and the milling machine using the multifunctional milling fixture have the beneficial effects that the machining efficiency is high, the structure is simple, the use is facilitated, the clamping reliability and stability are high, front and back surface machining can be conducted after only one step of clamping and radian needed by a workpiece can be machined. The milling fixture can satisfy the demand of 360-degree rotary machining of T-shaped, L-shaped, trapezoidal and flat parts.

Description

【Technical field】 [0001] The invention relates to a milling fixture for a milling machine, in particular to a multifunctional milling fixture which can be installed on a milling machine table for 360-degree rotation to process T-shaped, L-shaped, trapezoidal and flat parts. 【Background technique】 [0002] With the development of science and technology, the requirements for the manufacturing accuracy of product parts are getting higher and higher, and there is an urgent need for ultra-precision machining equipment, especially ultra-precision machining machine tools. The design and manufacture of its core components will affect the machining accuracy and surface quality of parts. . In the design of processing machine tools, the workpiece clamping system is a very critical part, and its structural design and manufacturing accuracy will directly affect the dimensional accuracy and shape accuracy of the processed parts. [0003] In the milling process, we often encounter some ir...

AI Technical Summary

Problems solved by technology

One side of the workpiece needs to be clamped twice. For the workpiece that needs to be processed on the front and back sides, it needs to be clamped four times, which affects the machining accuracy of the parts, affects the production efficiency, and increases the physical fatigue of the workers.

[0008] 2. Increased risk factor

When the workpiece is clamped, if the clamping force is not enough, it will easily cause the workpiece to fly off, and because the two ends of the workpiece are padded to make the middle part suspended, the contact area of ​​the clamping is reduced, and the friction force is also reduced accordingly. It is easy to cause the workpiece to fall off and hit the milling cutter

[0009] 3. Inconvenient processing

Since the workpiece is clamped and fixed, it is pressed downwards on the workpiece with a code tool, and then locked on the workbench with bolts, and the workpiece is small, so the nuts of the bolts are generally higher than the workpiece, and the milling cutter is from the workpiece. The top of the rotation, so that the height of the nut hinders the milling cutter, so that the processing depth of the workpiece is affected

[0010] 4. The processing accuracy is not high and it is easy to produce waste products

Due to the need to add pads and secondary clamping when the workpiece is processed, it is easy to cause the slope ratio to be incorrect when the workpiece is processed, and there are steps on the surface of the workpiece, etc.

[0011] 5. Unable to process the arc required by the workpiece

For workpieces that need to be processed in radians, none of the above methods can meet this demand, which limits the breadth of processing and cannot meet production needs in time.
