Description
Technical field
The utility model relates to a kind of lathe boring cutter clamping device, belongs to metal processing apparatus field.
Background technology
Bore hole on lathe at present, generally adopts equipment on turning-machine for setting-on cutting tools to adjust the method for elevation of the cutter center, adopts screw directly to compress knife bar simultaneously and fixes, and it exists following shortcoming:
1, adopt equipment on turning-machine for setting-on cutting tools to adjust elevation of the cutter center, in the time changing the outfit cutter, need to readjust centre-height, expend a large amount of time, efficiency is lower, and installation accuracy is low.
2, directly compress knife bar with screw, easily produce vibration when turning, workpiece does not reach the requirement of machining accuracy, makes point of a knife angle non-adjustable whole, and processing is inconvenient; In addition, screw directly contacts with knife bar, easily makes knife bar distortion or screw damage.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model aims to provide a kind of do not need to readjust while changing cutter center cutter height, both lathe boring cutter clamping devices that also laborsaving and mounting cutter precision is high that saves time.
To achieve these goals, this use is by the following technical solutions novel:
A kind of lathe boring cutter clamping device, comprise tool rest pedestal, also comprise the ER elastic collet chuck being arranged in tool rest pedestal and the locking nut that is positioned at ER elastic collet chuck outside, described tool rest pedestal comprises " protruding " font cuboid main body, in main body, be provided with the installing hole that boring bar and ER elastic collet chuck are installed, described installing hole is through hole, its one end is cylindrical installing hole, the other end is conical installing hole, the axis direction that described tool rest pedestal is installed nose end along taper shape is provided with clamping face, be arranged with locating surface in parallel with clamping face, the distance of clamping face and locating surface is less than tool rest pedestal width.
Described tool rest pedestal one side is provided with locating hole.
Described clamping face is through fine grinding and modifier treatment.
Described locating surface is through fine grinding and modifier treatment.
Described conical installing hole is through fine grinding and modifier treatment.
The tapering of the conical installing hole in described installing hole one end is 16 °.
Compared with prior art, the utlity model has following advantage:
1. ER elastic collet chuck and this tool rest pedestal are supported the use, for the bore hole of turning processing, have that clamping force is large, clamping range wide, precision advantages of higher, met the requirement to machining accuracy; While changing cutter, need not adjust again the distance (centre-height) between clamping face and locating surface, only need to change corresponding ER elastic collet chuck, just can the different cutter of quick and easy replacing.
2. on this tool rest pedestal, designed special positioning reference plane, guarantee that this positioning reference plane equates with lathe center is high all the time to the distance at pedestal taper hole center, when installation, do not need to adopt equipment on turning-machine for setting-on cutting tools or other any auxiliary adjustment measure, Cutting tool installation manner is convenient, fast, and installation accuracy is high; On tool rest pedestal, designed special clamping face, directly do not contacted knife bar, therefore knife bar is not yielding, has improved the service life of knife bar and pinching screw.
3. this tool rest utilizes the circumferential elastic force of ER elastic collet chuck, the knife bar that is fixedly clamped, to knife bar without any damage.Between ER elastic collet chuck and pedestal, adopt cone match simultaneously, guaranteed axiality between knife bar and tool rest pedestal taper hole, reduced the rigging error between each parts, reduced the impact of equipment error on part processing precision.
4. on tool rest, designed auxiliary positioning screw, can fast aligning boring cutter position of tool tip by adjusting screw, alleviate the dependence of workman being processed to experience.
5. this tool rest pedestal is through modifier treatment, durable in use; Locating surface, clamping face and taper hole all pass through fine grinding and process, and have guaranteed location, machining accuracy.
