Numerical control three-tip carpenter's drill tapping machine

Abstract

The invention discloses a digital control three points woodworking drills opening machine, which comprises a frame, a grinding wheel, a clamp device, a feeding device, a grinding wheel shape repairing device, a positioning machine, a stabilizer and a controller; the grinding wheel and the feeding device are arranged on the frame; the grinding wheel used for coping drills is connected with a grinding wheel drive motor; the clamp device is arranged on the feeding device, which comprises a clamping head, an index head and a clamping air cylinder, the clamp head used for fixing the drills and the index head used for controlling he angle of the drills are both connected with the clamping cylinder; the feeding device and the feeding motor are connected with each other and can be far or near from the grinding wheel; the clamping device and the feeding device and the grinding wheel repairing device are all connected with the controller. The invention can precede opening to all kinds of three points woodworking drills and the chamfer of key slot milling cutter, a vertical cutter and of part shapes, and the process accuracy and the efficiency is high; the safety is good and the operation is convenient.

Description

technical field [0001] The invention relates to a numerically controlled machine tool, in particular to a numerically controlled three-pointed woodworking drill for shedding processing of various three-pointed woodworking drills, keyway milling cutters, end mills and part-shaped chamfers, etc. machine. Background technique [0002] With the higher and higher requirements for machining precision, higher requirements are also put forward for various processing tools. At present, there are mainly three methods for woodworking drilling opening processing: the first is that the operator directly holds the drill bit 1 in his hand. Grinding on the grinding wheel 2, using manual feeding, see Figure 1; the second is to set the guide sleeve 3 at a fixed position in front of the grinding wheel 2, insert the drill bit 1 into the guide sleeve 3, and then use the manual feeding method, see Figure 2; The third is to add indexing pin 4 and locking bolt 5 on the basis of the original guide ...

[0002] With the higher and higher requirements for machining precision, higher requirements are also put forward for various processing tools. At present, there are mainly three methods for woodworking drilling opening processing: the first is that the operator directly holds the drill bit 1 in his hand. Grinding on the grinding wheel 2, using manual feeding, see Figure 1; the second is to set the guide sleeve 3 at a fixed position in front of the grinding wheel 2, insert the drill bit 1 into the guide sleeve 3, and then use the manual feeding method, see Figure 2; The third is to add indexing pin 4 and locking bolt 5 on the basis of the original guide sleeve, and set the guide sleeve 3 on the movable cross slide 6 for positioning. Although there is positioning in this way, the Since it is still manual operation, the speed of feed and the length of contact time with the grinding wheel cannot be consistent, the error of grinding is very large, and the control of end tooth runout is > 0.3mm

Moreover, in the existing processing methods, people operate on the front of the grinding wheel, and the phenomenon of sand particles collapsing into the eyes often occurs. If the feeding is too forceful, the grinding wheel will be broken, and safety accidents will also occur.

Therefore, the current methods of woodworking drilling opening processing all have the disadvantages of poor precision and poor safety.
