Abstract
The utility model relates to a cutter holder positioning structure. The cutter holder positioning structure comprises a ram and a cutter holder which is connected to the bottom of the ram. The cutter holder positioning structure is characterized in that an axle hole is formed in the lower end face of the ram, a connecting shaft is arranged at the top end of the cutter holder, the connecting shaft stretches into the axle hole of the ram, and the step surface of the cutter holder abuts against the surface at the bottom of the ram; a threaded hole is formed in the bottom face of the axle hole of the ram, a bolt bar body partially penetrates through the cutter holder and then is connected to the threaded hole, and thus the cutter holder is fixed on the bottom face of the ram. According to the cutter holder positioning structure, cutter holder steps and a cutter holder extending shaft are used for positioning and supporting, leaping is prevented through bolt positioning, in this way, the vibration problem of the cutter holder caused by the action of counter-acting force and the vibration generated by the high-speed rotation of a machine tool is effectively solved, so that the instability problem is solved when a cutter is used for cutting workpieces, and machining quality is improved.
Description
Technical field
The utility model 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 purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of cutter holder location structure simple in structure, ingenious, rational is provided, and this structure can effectively solve existing cutter holder and locate irrational problem, effectively solves the problem of cutter holder vibration.
The technical scheme providing according to the utility model: 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 further improvement of the utility model, on described ram, on the face relative with axis hole, offer the through hole with counterbore.
The utility model compared with prior art, advantage is: the utility model 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 utility model.
The specific embodiment
Below in conjunction with concrete drawings and Examples, the utility model is described in further detail.
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 utility model, 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 utility model and the course of work are as follows: the connecting axle 4 that the cutter holder 3 in the utility model 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 utility model 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.
