Abstract
The utility model provides a floating tip device which comprises a base. A vertically upward guiding hole is formed in the base, the bottom of the guiding hole is provided with a plug, a guiding rod matched with the guiding hole in a sliding mode is arranged in the guiding hole, a spring is arranged between the bottom of the guiding rod and the plug, and a tip is arranged at the top of the guiding rod and provided with a limiting boss I preventing the tip from entering the guiding hole. When the floating tip device is used, a central hole at the lower end of a workpiece is aligned to the tip, the tip is downward pressed to perform downward motion, the guiding rod compresses the spring, a clamp clamps the workpiece at the position, and a machine tool begins to perform machining. After machining, the workpiece is released, the spring pressure enables the tip to perform upward motion, and feeding and discharging functions of an original mechanism arm are achieved. The floating tip device can utilize the original mechanism arm to achieve feeding and discharging of long workpieces and has the advantages of being simple in structure, low in manufacture cost and convenient to use.
Description
Technical field
The utility model relates to Machining Technology field, is specifically related to a kind of floating centre device.
Background technology
At present, in machining, when gear hobbing lathe automatic loading/unloading, some major axis tooth class workpiece are due to size reason, its length that enters gear-hobbing clamp has exceeded the design maximum stroke that standard machine tool loading and unloading manipulator promotes, and standard machine tool cannot carry out automatic loading/unloading.For this class workpiece, conventionally adopt method be exactly that the maximum lift stroke that increases loading and unloading manipulator is realized automatic loading/unloading function, but because the method need to redesign transformation to equipment, cost is high, the time of consumption is long, reforming technology complexity.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of floating centre device, has overcome above-mentioned weak point, has simple in structurely, and cost of manufacture is low, advantage easy to use.
The utility model discloses a kind of floating centre device, comprise base, described base is provided with pilot hole straight up, described pilot hole bottom is provided with plug, in described pilot hole, be provided with the guide post being slidably matched with pilot hole, between described guide post bottom and plug, be provided with spring, described guide post top is provided with top.
Further, described top being provided with prevents the top positive stop lug boss I that enters pilot hole.
Further, described plug and pilot hole threaded engagement.
Further, described be toply threaded with guide post.
Further, described guide post is provided with positive stop lug boss II, and described pilot hole is provided with the limited step for limiting positive stop lug boss II.
The beneficial effects of the utility model are: the utility model floating centre device, when use, workpiece lower end centre bore is aimed at top, and press down and make top moving downward, and make guide post Compress Spring, fixture is at this position clamping work pieces, and lathe starts processing; After machining, lax workpiece, spring pressure orders about top moving up, and has met the loading and unloading function that uses original manipulator.The utility model can utilize original manipulator to realize the loading and unloading to long class workpiece, has simple in structurely, and cost of manufacture is low, advantage easy to use.
Accompanying drawing explanation
In order to make object, technical scheme and the advantage of utility model clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model;
Schematic diagram when Fig. 2 is the utility model use;
Fig. 3 is the utility model A place enlarged diagram.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in the figure, the utility model floating centre device, comprise base 1, described base 1 is provided with pilot hole 2 straight up, described pilot hole 2 bottoms are provided with plug 3, in described pilot hole 2, be provided with the guide post 4 being slidably matched with pilot hole 2, between described guide post 4 bottoms and plug 3, be provided with spring 5, described guide post 4 tops are provided with top 6.Using the utility model to add man-hour to workpiece, workpiece lower end centre bore is aimed at top 6, press down and make top moving downward, and make guide post 4 Compress Springs 5, jig is at this position clamping work pieces, and lathe starts processing; After machining, lax workpiece, spring 5 pressure order about top 6 and move up, and have met the loading and unloading function that uses original manipulator.
In the present embodiment, described top 6 are provided with and prevent that top 6 enter the positive stop lug boss I 6a of pilot hole 2, and positive stop lug boss I 6a prevents that top 6 enter in pilot hole 2, cannot accurately position workpiece, causes mismachining tolerance.
In the present embodiment, described plug 3 and pilot hole 2 threaded engagement, facilitate plug 3 to pull down from base 1, changes the parts that damage.
In the present embodiment, described top 6 are threaded with guide post 4, for convenience detach, are convenient to plant maintenance.
In the present embodiment, described guide post 4 is provided with positive stop lug boss II 4a, and described pilot hole 2 is provided with the limited step 2a for limiting positive stop lug boss II 4a, limits at the stroke of pilot hole 2 for guide post 4.
Finally explanation is, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although by the utility model being described with reference to preferred embodiment of the present utility model, but those of ordinary skill in the art is to be understood that, can make various changes to it in the form and details, and not depart from the spirit and scope of the present utility model that appended claims limits.
