Abstract
The invention relates to a cutter clamp positioning structure. The cutter clamp positioning structure comprises a ram and a cutter clamp connected to the bottom of the ram. The cutter clamp positioning structure is characterized in that a shaft hole is formed in the lower end surface of the ram, a connecting shaft is arranged at the top end of the cutter clamp and extends into the shaft hole of the ram, and a step surface of the cutter clamp abuts against the bottom surface of the ram. A threaded hole is formed in the bottom surface of the shaft hole of the ram, a rod body of a bolt partially penetrates through the cutter clamp and then is connected to the threaded hole, and the cutter clamp is fixed to the bottom surface of the ram. The cutter clamp positioning structure carries out positioning and supporting through the cutter clamp step and an extending shaft of the cutter clamp, the bolt is used for positioning and preventing jumping, and vibration of the cutter clamp caused by reactive force on the cutter clamp and vibration caused by high-speed rotation of a lathe is effectively avoided. Therefore, the problem of instability caused when a cutter cuts a workpiece is resolved, and machining quality is improved.
Description
Technical field
The present invention relates to a kind of location structure, specifically a kind of cutter holder location structure being applicable in vertical tool holder.
Background technology
In vertical lathe, the positioning stablity of vertical cutter frame cutter holder is reliable, can realize in vertical lathe X-axis and Z axis and moving under reliable prerequisite, and be unlikely to not reach due to the workpiece size that the displacement of cutter holder and vibration make to process the requirement of expection.At present, the mode of cutter holder location is varied, and it is very long that the projecting shaft of common cutter holder all can be done, and difficulty of processing is large, cost is high, and the vibrations that machine tool high speed rotary course produces simultaneously also can cause the vibration of cutter holder, cause the not steady of cutting workpiece.In view of the problem of above-mentioned existence, in the urgent need to developing a kind of novel cutter holder location structure.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of cutter holder location structure simple in structure, ingenious, rational is provided, this structure can effectively solve existing cutter holder and locate irrational problem, effectively solves the problem of cutter holder vibration.
According to technical scheme provided by the invention: a kind of cutter holder location structure, comprise ram and be connected in the cutter holder of described ram bottom, be characterised in that: described ram lower surface offers axis hole, cutter holder top has a connecting axle, described connecting axle stretches in ram axis hole, and the step surface of cutter holder is resisted against in ram lower surface; Described ram axis hole bottom surface offers screwed hole, and bolt shank portion is connected on described screwed hole after running through cutter holder, and cutter holder is fixed on to ram bottom surface.
As a further improvement on the present invention, on described ram, on the face relative with axis hole, offer the through hole with counterbore.
The present invention compared with prior art, advantage is: the present invention adopts the projecting shaft positioning supports of cutter holder step and cutter holder, Bolt to position prevents from jumping, so just efficiently solve cutter holder and be subject to the effect of reaction force, rotate the vibrations that produce and the vibration of the cutter holder causing with machine tool high speed, thereby solved the not steady of Tool in Cutting workpiece, improved crudy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1, comprise ram 1, bolt 2, cutter holder 3, connecting axle 4, screwed hole 5, counterbore 6, through hole 7 etc.
As shown in Figure 1, a kind of cutter holder location structure of the present invention, comprise ram 1 and be connected in the cutter holder 3 of described ram 1 bottom, described ram 1 lower surface offers axis hole, cutter holder 3 tops have a connecting axle 4, described connecting axle 4 stretches in ram 1 axis hole, and the step surface of cutter holder 3 is resisted against in ram 1 lower surface; Described ram 1 axis hole bottom surface offers screwed hole 5, and bolt 2 shank portion are connected on described screwed hole 5 after running through cutter holder 3, and cutter holder 3 is fixed on to ram 1 bottom surface.
On described ram 1, on the face relative with axis hole, offer the through hole 7 with counterbore 6.
Operation principle of the present invention and the course of work are as follows: the connecting axle 4 that the cutter holder 3 in the present invention connects by its top one is installed in the axis hole of ram 1 lower end, and connecting axle 4 adopts basic shaft system, the step on cutter holder 3 and ram 1 with the matching relationship of axis hole
The present invention adopts the projecting shaft positioning supports of cutter holder step and cutter holder, Bolt to position prevents from jumping, so just efficiently solve cutter holder and be subject to the effect of reaction force, rotate the vibrations that produce and the vibration of the cutter holder causing with machine tool high speed, thereby solved the not steady of Tool in Cutting workpiece, improved crudy.
