Abstract
The utility model discloses a kind of lathe tools, it comprises chuck and chuck lid, chuck have run through it stretch tool bore, the dismounting of chuck lid is connected to the Single port stretching tool bore; Stackingly in tool bore have at least two panels along the cutter of its hole wall slippage, to be provided with pre-fault trough at the side opening of cutter stretching, the groove trend of pre-fault trough and the sword of the cutter edge of a knife are to identical; Chuck offers the locating hole being communicated to cutter, has keeper to pass locating hole and compresses stacking cutter and stretching on tool bore hole wall.The purpose of this utility model is to provide a kind of after edge wear, and by eliminating pre-fault trough, cutting blade part, namely can reduce the original shape of blade, so that repair blade fast.
Description
Technical field
The utility model relates to a kind of sharpening of cutting edge, and as cutter, and annex, as holding cutter, more particularly, it relates to a kind of NC cutting tool.
Background technology
NC cutting tool is the instrument for machining in machine-building, also known as cutting element.The cutting element of broad sense both comprised cutter, also comprised grinding tool; " NC cutting tool " is except the blade cut simultaneously, also comprises the annex such as knife bar and handle of a knife.
Usual NC cutting tool adopts clip type, is namely be fixed on Digit Control Machine Tool;
Traditional clip type NC cutting tool comprises rotary type and fixed further;
Wherein, fixed NC cutting tool is clamping on the fixture of numerical control vehicle window, carries out chip, polishing by the high-speed rotation of object.
It is in the process of chip, and blade easily occurs wearing and tearing and even damages.
After blade and even edge of a knife fracture, its intrinsic cutting edge shape is destroyed, and is difficult to the shape of being repaired former blade by polishing.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of after edge wear, and by eliminating pre-fault trough, cutting blade part, namely can reduce the original shape of blade, so that repair blade fast.
For achieving the above object, the utility model provides following technical scheme:
A kind of lathe tools, it comprises chuck and chuck lid, described chuck have run through it stretch tool bore, stretch the Single port of tool bore described in described chuck lid dismounting is connected to;
Stackingly in tool bore have at least two panels along the cutter of its hole wall slippage, to be provided with pre-fault trough at the side opening of described cutter described stretching, the groove trend of described pre-fault trough and the sword of the described cutter edge of a knife are to identical;
Described chuck offers the locating hole being communicated to cutter, has keeper to pass described locating hole and compresses stacking cutter and stretching on tool bore hole wall.
Preferably, described locating hole is communicated to the side of described cutter, and another side that described keeper compresses described cutter relative positioning hole through locating hole is being stretched on tool bore hole wall.
Preferably, described locating hole is communicated to the side of described cutter, and the another side that described keeper compresses described cutter relative positioning hole through locating hole is being stretched on tool bore hole wall.
Preferably, described keeper is screw, and described locating hole is screwed hole, and described screw abuts the side of described cutter after screwing in screwed hole.
In addition, the two sides of described cutter all offer pre-fault trough.
Compared with prior art, blade operative portion of the present utility model is after breaking or occurring scar, directly by pre-fault trough cutoff tool mouth, namely the original state of the edge of a knife can be recovered fast, now by the burr that the pre-fault trough of simple processing removal stays when disconnecting, the repair of blade namely can be completed fast.

Accompanying drawing marks: 11, chuck; 111, tool bore is stretched; 112, chuck fixing hole; 113, deep gouge; 1131, locating hole; 12, chuck lid; 121, tool bore is allowed; 122, chuck lid fixing hole; 2, cutter; 21, the edge of a knife; 22, pre-fault trough; 3, chuck lid dog screw; 4, chuck dog screw.
Detailed description of the invention
Referring to figs. 1 through Fig. 6, the utility model numerically controlled lathe blade embodiments is described further.
As shown in Figure 1, a kind of lathe tools, it comprises chuck and chuck lid, chuck have run through it stretch tool bore, chuck covers the chuck lid fixing hole offering counterbore, chuck fixing hole is offered, by screwing in chuck lid fixing hole and chuck fixing hole by chuck lid dog screw, with the end face of geometrical clamp upper shield at chuck at the Single port place of stretching tool bore.
Meanwhile, cover at chuck and offer bore and be less than the tool bore that allows stretching tool bore bore, only have the edge of a knife of cutter to pass cutter relieving groove.Prevent cutter from breaking.
Preferably, stackingly in tool bore four are had along the cutter of its hole wall slippage stretching; This considers that cutter groove adopts the carbide alloy such as wolfram steel to make, and be difficult to cut off its pre-fault trough offered, and independent cutter is that appearance is scissile, therefore by stacking cutter, the while of providing enough intensity, also can cuts off pre-fault trough separately, rapidly.
Meanwhile, the groove trend of pre-fault trough and the sword of the cutter edge of a knife are to identical; The object of such design is, after edge of a knife fracture, cuts off pre-fault trough and is polishing a little just can reinvent the new edge of a knife to cutting off the burr that produces of pre-fault trough.
The side opening of chuck is provided with deep gouge, offers the locating hole being communicated to cutter in deep gouge, and chuck dog screw, while screw-in locating hole, can compress stacking cutter and stretch on tool bore hole wall.So that cutter and chuck are fixed, prevent in process, cutter produces and rocks, output defect ware.
Preferably, the locating hole of chuck side can be multiple, and this enforcement preferably adopts five chuck dog screws to be pressed on by cutter to stretch on the hole wall of tool bore, further enhances cutter and is pressed on stability when stretching on tool bore hole wall.
Simultaneously, all offer pre-fault trough in the two sides of cutter, so that more quick when the cutting off tool edge of a knife.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
