Description

Cutter spindle is to tool setting device

Technical field

The utility model relates to mechanical, and particularly a kind of cutter spindle is to tool setting device.

Background technology

In the process of workpiece, account for sizable ratio in the process-cycle non-cutting times such as work-handling, cutter adjustment, wherein the adjustment of cutter had both been wasted time and energy, and being difficult for again accurately also needs trial cut at last.Statistics shows, the processing of a workpiece, and the pure time kept in reserve approximately only accounts for 55% of total time, and account for 45% non-cutting times such as clamping and tool setting.Therefore, tool setting gauge just demonstrates great superiority.And there are shortcomings such as the tool setting precision is relatively poor, work is unreliable, the life-span short, and is with high costs in existing tool setting gauge.

Summary of the invention

Problems such as the purpose of the utility model is to provide a kind of cutter spindle to tool setting device, has solved relatively poor, unreliable, the life-span weak point of working of tool setting precision that prior art exists, and is with high costs.

The above-mentioned purpose of the utility model realizes through following technical scheme:

Cutter spindle comprises pedestal 1, pillar 2, guide pillar 3, gear 4, sliding sleeve 5, connecting plate 6, pressing plate 7, screw I 8, table cover 9, gripping sleeve 10, table 11, screw II 12, traveller 13, screw III 14, cutter 15, handle of a knife 16, broach shell 17, axle 18, jackscrew 19, handle 20, nut 21, screw IV 22 to tool setting device; Wherein, Be fixed with pillar 2 below the pedestal 1, guide pillar 3 is fixed on the pedestal 1 through screw IV 22, and sliding sleeve 5 cooperates with this guide pillar 3; Pressing plate 7 is connected with sliding sleeve 5 through screw I 8; Gear 4 is connected with sliding sleeve 5 through axle 18, nut 21, and meshes with tooth bar on the guide pillar 3, and handle 20 passes through jackscrew 19 and is connected with sliding sleeve 5; Sliding sleeve 5 is connected with table cover 9 through connecting plate 6, and this table overlaps 9 interior socket gripping sleeves 10 and holds out against through screw II 12, and this gripping sleeve 10 cooperates with the table bar of table 11, and traveller 13 is arranged at table cover 9 internal table bar lower ends , Broach shell 17 is fixed on the pedestal 1.

Described table 11 is dial gauge or amesdial.

The beneficial effect of the utility model is: the tool setting precision is good, and accuracy rating is at 0.01～0.005mm.Avoided the problem that the work of electronic type tool setting gauge is unreliable, the life-span is short.The price of existing electronic type tool setting gauge is 6～70,000 yuan, and this tool setting device cost is 2000～3000 yuan, and low cost of manufacture is practical.

The specific embodiment

Further specify the detailed content and the specific embodiment thereof of the utility model below in conjunction with accompanying drawing.

Referring to Fig. 1 to Fig. 4; The cutter spindle of the utility model comprises pedestal 1, pillar 2, guide pillar 3, gear 4, sliding sleeve 5, connecting plate 6, pressing plate 7, screw I 8, table cover 9, gripping sleeve 10, table 11, screw II 12, traveller 13, screw III 14, cutter 15, handle of a knife 16, broach shell 17, axle 18, jackscrew 19, handle 20, nut 21, screw IV 22 to tool setting device, wherein, is fixed with pillar 2 below the passive pedestal 1; Guide pillar 3 is fixed on the pedestal 1 through screw IV 22; Sliding sleeve 5 and these guide pillar 3 sockets, guide pillar 3 moves up and down sliding sleeve 5 above that, and pressing plate 7 is connected with sliding sleeve 5 through screw I 8; Gear 4 is connected with sliding sleeve 5 through axle 18, nut 21; And with guide pillar 3 engagement, handle 20 is connected with sliding sleeve 5 through jackscrew 19, is respectively applied for mobile or locks sliding sleeve 5; Sliding sleeve 5 is connected with table cover 9 through connecting plate 6; Cooperate gripping sleeve 10 in this table cover 9; This gripping sleeve 10 cooperates with the table bar of table 11, and holds out against through screw II 12, and table 11 is used to measure the variation of tool length; Traveller 13 is arranged at table cover 9 internal table bar lower ends and contacts with cutter 15, and screw III 14 avoids traveller to fall down; Broach shell 17 is fixed on the pedestal 1, is used to locate the handle of a knife 16 of tested milling cutter.

Described table 11 is dial gauge or amesdial.

When the utility model uses in reality, at first basic-cutter and measured cutter are respectively charged in the corresponding broach shell 17, clamping is firm on pedestal 1.The plate 6 drive tables that are rotationally connected then cover 9, gripping sleeve 10 and table 11 (dial gauge or amesdial), screw II 12, traveller 13, screw III 14 are rotated.Benchmark cutter and handle of a knife are inserted in the broach shell 17.Release handle 20 afterwards; Adjustment gear 4 moves up and down sliding sleeve 5, and connecting plate 6 is rotated back into traveller 13 centers and benchmark cutter shaft on the highest point of a knife point consistent location, makes sliding sleeve 5 simultaneously on the integer scale value a on the guide pillar 3; Tighten handle 20, make guide pin bushing 5 fixing on guide pillar 3.And then adjustment form 11, contact (certain decrement is arranged), traveller 13, the cutter 15 of table 11 are coupled together, let the pointer of table 11 reach zero-bit simultaneously.The tram of table 11 just mixes up like this.Write down the scale value of sliding sleeve 5 on guide pillar.Plate 6 is rotationally connected; Take basic-cutter 15 and handle of a knife 16 away, tested cutter and handle of a knife are together inserted in the tapered sleeve 17, adjust guide pin bushing 5 again; Guide pin bushing is fixed on an integer scale position b; Connecting plate 6 rotated back into make traveller 13 and the highest point of a knife point contact position of tested cutter,, calculate the mobile distance of actual axial length h=b-a+ table of tested cutter relative datum cutter again according to the rotation situation of table 11.
