Description
Technical field
The utility model belongs to machine tool technical field, particularly relates to a kind of boring cutter bar device for processing tapering arc blind hole that can use on numerically controlled lathe.
Background technology
In the process of tapering arc blind hole, because blind hole is comparatively dark and root shape complicated and size is less, traditional lathe and deep hole drilling and boring machine all do not possess processing conditions, can't process the shape and size in hole.Common way is on deep hole drilling and boring machine, utilize forming flat drill to process.Because the forming flat drill manufacturing cycle is long, costly, process is easily forged a knife, and require high, and crudy not easily ensures to operator's level of skill.Given this, a kind of boring cutter bar device for processing tapering arc blind hole of my company designs.
Summary of the invention
The purpose of this utility model overcomes above-mentioned deficiency of the prior art provides that a kind of structure is simple, low cost of manufacture, operating efficiency are high and the boring cutter bar device for processing tapering arc blind hole that the tapering blind hole crudy processed is high.
The technical solution of the utility model is achieved in that a kind of boring cutter bar device for processing tapering arc blind hole, comprise boring cutter bar, the counterweight part that described boring cutter bar comprises push type broach part, anti-interference part, the clamping part be connected with numerically-controlled slide on numerically controlled lathe and prevents knife bar from vibrating, described push type broach part is arranged on boring cutter bar foremost, described push type broach part front end offers the cutter groove installing cutter head, described cutter slot is outside boring cutter bar, and direction and boring cutter bar axis being parallel, described cutter head is vertically mounted in described cutter groove.
The bottom of the front end of described anti-interference part is provided with a curved tapers, and the transitional taper angle of described curved tapers is less than the blind hole cone angle of workpiece to be machined.
The cross section of described clamping sections transverse axis direction is an inverted asymmetrical T font structure, and the upper surface of T font structure is arcwall face.
The good effect that the technical solution of the utility model produces is as follows: described push type broach part is provided with cutter groove, and cutter slot is outside boring cutter bar, and direction and boring cutter bar axis being parallel, to ensure the smooth processing of product blind hole tapering, the rigidity of boring cutter bar can be increased again.The clamping position being designed with anti-interference part after push type broach position and being connected with numerically-controlled slide on numerically controlled lathe, product internal via shape and cutter numerical control processing track is taken into full account during described anti-interference partial design, knife bar is anterior, a bottom mill off part, and transitional taper angle that is anterior and bottom is less than blind hole cone angle, when preventing cutter from rotating and product interfere while improve the crudy of blind hole, the smooth processing of product tapering arc blind hole can be ensured, the rigidity of boring cutter bar can be increased again; Described clamping part is used for and number visits lathe saddle cooperation, the counterweight part preventing knife bar from vibrating is designed with after clamping part, described counterweight part is the counterweight part of knife bar as boring cutter bar lengthening certain length after clamping part, to prevent boring cutter bar device front end from stretching out long, thus when causing work, boring cutter bar rigidity deficiency is vibrated.

Detailed description of the invention
A kind of boring cutter bar device for processing tapering arc blind hole, as Fig. 1, 2, shown in 3, comprise for Tool-rest of Numerical Control Lathe match connect boring cutter bar, described boring cutter bar comprises push type broach part 1 foremost, the anti-interference part 2 of next-door neighbour's push type broach part, the clamping part 3 be connected with numerically-controlled slide on numerically controlled lathe and the counterweight part 4 preventing knife bar from vibrating, described push type broach part is arranged on boring cutter bar foremost, described push type broach part front end offers the cutter groove 5 installing cutter head, described cutter slot is outside boring cutter bar, and direction and boring cutter bar axis being parallel, described cutter head is vertically mounted in described cutter groove, utilize 3 M8 bolt presses.
The bottom of the front end of described anti-interference part is provided with a curved tapers, and the transitional taper angle of described curved tapers is less than the blind hole cone angle of workpiece to be machined.Anti-interference partial shape design time take into full account shape of product and numerical control processing track, when preventing cutter from rotating and product interfere, the smooth processing of product tapering arc blind hole can be ensured, the rigidity of boring cutter bar can be increased again.
The cross section of described clamping sections transverse axis direction is an inverted asymmetrical T font structure, and the upper surface of T font structure is arcwall face.Described counterweight part is the counterweight of knife bar as boring cutter bar lengthening certain length after clamping part, long to prevent boring cutter bar front end from stretching out, then operationally because rigidity deficiency is vibrated.
The using method of the utility model boring cutter bar device: on numerically controlled lathe, tapering arc blind hole divides two sections of machine-shapings, the boring cutter bar device machine-shaping in the machine-shaping of concrete See Figure 4:C section Common boring cutter bar, D section the present embodiment.
