Auxiliary device for manufacturing long and thin cutter

Abstract

The invention relates to tooling equipment used in a cutter manufacture process, in particular to an auxiliary bracket which is applicable to the processing of long and thin cutter. The bracket comprises a base, wherein the base is provided with holes or slots which are arranged along the direction of up and down; a support bar is matched with the slots or the slots and moves along the direction limited by the holes and the slots; a positioning mechanism which limits the movement of the support bar is arranged between the base and the support bar; at least one end of the support bar is provided with an arc notch; and arc surfaces forming the arc notch is matched with the bar surface of the cutter to be machined. In the technology, the support rod can conveniently move up and down along the limit direction of the holes or the slots on the base; when the bar of a part to be machined is properly contacted with the arc notch on the support bar, the bar is fixed by the support bar of the positioning mechanism so that the arc notch of the support bar can support the bar body of the part to be machined constantly; the cutter to be machined is generally a deep hole drill; and under the supporting action of the support bar, the machining accuracy of the cutter to be machined can be ensured, and the yield can be effectively improved.

Description

technical field [0001] The invention relates to a tooling device used in the tool manufacturing process, in particular to an auxiliary bracket suitable for processing slender tools. Background technique [0002] In the process of grooving and relief grinding with a five-axis grinder for the integral alloy drill bit, because the tool is in a cantilever state, it is very easy to break the tool if the center frame is not used for the processing of the slender tool. Imported equipment is used in the prior art, such as figure 1 , 2 As shown, wherein the center frame includes a base 10, a semicircle center frame 20 is installed on the top of the base 10, and the semicircle center frame 20 is a block-shaped member. The rod body of the long tool 30 is located in the long groove 21, the long groove 21 opens upward, and the bottom of the base 10 is connected with a pneumatic lifting device 40. The pneumatic lifting device 40 can realize rapid lifting. Along a section of length H, p...

AI Technical Summary

Problems solved by technology

[0004] 1. It is not easy to adjust the semicircular center frame 20, and it takes a long time to adjust the work, which affects work efficiency;

[0005] 2. In the process of adjusting the semi-circular center frame 20, when the locking screw is tightened, it is easy to cause the tool to be deformed by force or the gap is too large and the support effect is poor, which affects the processing quality;

[0006] 3. Each machining tool of a diameter size requires a semi-circular center frame attachment of the corresponding size. When it comes to manufacturing tools of special specifications and sizes, the delivery cycle of imported accessories is too long to meet production needs;

[0007] 4. The semi-circular center frame 20 is complex in shape, requires high precision, and is difficult to manufacture
