Embodiment 1

[0058] A kind of drill device of arbitrary shape hole of the present embodiment, comprises drill bit 5, side vane assembly and drill track disc 4; Motion is transformed into surface motion, such as figure 2 As shown, the first layer of the side blade combination is the active side blade 1, and the bottom layer is the driven side blade 3; the middle layers of side blades are the middle side blades 2; the connecting rod 6 and the connecting rod The shaft 61 is hinged. The number of layers of the middle side blade 2 can be adjusted according to the needs of the surface movement area of ​​the workpiece drilling. In this embodiment, the middle side blade 2 is one layer; the hinged connection can transfer the rotation mode of the prime mover down layer by layer The drill bit 5; the drill track disc 4 is stuck at the fixed connection between the side blade assembly and the drill bit 5, limiting the surface movement of the drill bit 5 to the shape set by the drill bit track disc 4; ...

Embodiment 2

[0065] A kind of arbitrarily shaped drill bit device of the present embodiment, the basic structure is the same as embodiment 1, and the improvement is that: the side blades are all in the shape of a triangular or quadrangular or pentagonal or hexagonal star, such as figure 1 , 4 As shown, the triangular star shape can be selected in this embodiment. Compared with the polygonal plate shape, the effect of the star shape is to reduce the visual obstruction of drilling personnel. The visual effect of the triangular star shape is the best, and the efficiency of surface movement is higher; The rod 6 and the connecting rod shaft 61 symmetrically hinge the three distal ends of the triangular star-shaped side blades of two adjacent layers. A driving blade shaft 11 is fixedly connected to the center of the upper surface of the driving side blade 1, and is detachably fixedly connected to the prime mover through the driving blade shaft 11; a driven blade shaft 31 is fixedly connected to ...

Embodiment 3

[0073] A kind of arbitrarily shaped drill bit device of the present embodiment, such as image 3 Shown, basic structure is with embodiment 2, and processing is as Figure 7 The shown arc-shaped hole workpiece 20, the steps are:

[0074] Step 1. Installation: insert the prime mover connecting shaft 7 into the groove of the prime mover power end, and detachably connect the driven blade shaft 31 with the fixed end of the drill bit 5;

[0075] Step 2, the design and installation of the drill track disc 4: take a square or circular panel, pierce an arc-shaped hole in its center, and fix it horizontally between two uprights;

[0076] Step 3, positioning: Insert the drill bit 5 into the arc hole, and stick the driven blade shaft 31 into one end of the arc hole;

[0077] Step 4. Drilling: The working end of the drill bit 5 is against the workpiece to be drilled, the prime mover is started, and a single hole is first drilled by holding the positioning block 8;

[0078] Step 5, push:...

Abstract

The invention discloses a drill bit device for holes in arbitrary shapes and a drilling method of the drill bit device, and belongs to the technical field of mechanical drilling. The drill bit device for the holes in the arbitrary shapes comprises a drill bit and further comprises a side blade assembly and a drill bit trajectory disc. The two ends of the side blade assembly are detachably and fixedly connected with a prime motor and the drill bit correspondingly, and point movement of the drill bit is converted into surface movement. The drill bit trajectory disc is clamped at the fixed joint of the side blade assembly and the drill bit, and surface movement of the drill bit is limited in the shape set by the drill bit trajectory disc. According to the drill bit device for the holes in the arbitrary shapes and the drilling method of the drill bit device, the side blade assembly and the drill bit trajectory disc synergistically act; the side blade assembly converts point movement of the drill bit into surface movement at first; then the shape of a machined drill hole is limited through the drill bit trajectory disc; the drill hole of which the shape is the same as that of the drill bit trajectory disc can be machined out by replacing the drill bit trajectory disc; the drilling efficiency and the drill bit universality are improved; and the manufacturing cost of the drill bit is far larger than that of the drill bit trajectory disc, and therefore, the manufacturing cost is also reduced.

Description

technical field [0001] The invention belongs to the technical field of mechanical drilling, in particular to a drill device for a hole with any shape and a drilling method thereof. Background technique [0002] In the field of drilling processing, when drilling long workpieces such as slide rails, the workpiece must be positioned first, and then the tool is used for drilling. However, the tools used in general drilling equipment are fixed in size and can only process holes of a single size. If the workpiece needs to process multiple types or sizes of holes, workers must repeatedly change different tools for processing in the same processing process, the degree of automation is low, and the drilling efficiency is low. When encountering the problem of machining arc holes, the machining of arc holes is mainly realized by milling, boring, turning, and EDM. Processing arc holes on non-metallic sheets can only be obtained by milling with a small-diameter arc milling cutter after...
