Abstract
The utility model discloses an elastic tensioning fixture, which is simple in structure, reliable in working and convenient in framework assembly and disassembly. The elastic tensioning fixture comprises a fixture core connected with a spindle, and one end of the fixture core is connected with a fixture core shaft connected with a sleeving framework. The elastic tensioning fixture is characterized in that an axial long groove is arranged on the fixture core shaft to divide the fixture core shaft into an upper fixture core shaft piece and a lower fixture core shaft piece, the length of the long groove is larger than the width of the sleeving framework, and convex plates protruding upwards and used for preventing the framework from slipping are arranged on the outer surfaces of the upper fixture core shaft piece and the lower fixture core shaft piece or on the outer surface of the upper fixture core shaft piece or the lower fixture core shaft piece. Because the axial long groove is arranged on the fixture core shaft, the fixture core shaft at sleeving section of the framework has elasticity with a certain tension force and resultant force. After the framework is sleeved in, the framework is fixed on the fixture core shaft by means of elasticity of the fixture core shaft and is blocked by the convex plates. The structure has the advantages of being reliable in connection and convenient in framework assembly and disassembly.
Description
Technical field
The utility model relates to a kind of frock on the automatic coil winding machine, comes the tool of clamping more specifically to the automatic coil winding machine driving shaft.
Background technology
When coil-winding; General elder generation is installed to the skeleton of coil on the tool (the fixedly frock of skeleton); Again tool is installed on the main shaft of automatic coil winding machine and by main shaft clamping back skeleton and rotates, implement coil-winding, after the wire-wound on the skeleton is good with main shaft; The skeleton that needs to wind coil takes off from tool, changes coiling again behind the empty skeleton.Therefore, the loading and unloading of skeleton on tool will be very frequent, will be directly connected to the operating efficiency and coiling quality of coiling for the connected mode of design framework and tool.And seem complicated on the connected mode of common skeleton and tool, and efficient is lower when loading and unloading, influences threading speed.
The utility model content
The purpose of the utility model provides a kind of simple in structure, reliable operation, the elastic tension formula tool that skeleton is easy to loading and unloading.
In order to reach above-mentioned requirements; The technical scheme that the utility model adopted is: it includes the tool core that is connected with main shaft; Be connected with the tool mandrel of socket skeleton at an end of tool core, it is characterized in that having on the tool mandrel axial elongated slot, the tool mandrel is divided into upper and lower tool mandrel sheet; The length of elongated slot is shaped on upper and lower tool mandrel sheet or the outer surface of one of them and prevents the skeleton slippage and the convex of epirelief greater than the width of socket skeleton.
Elastic tension formula tool according to such scheme is made owing on the tool mandrel, have axial elongated slot, makes the tool mandrel have the elasticity of certain opening and closing power in the skeleton section of being inserted in; When skeleton is inserted in the tool mandrel; Upper and lower tool mandrel sheet closes up, and utilizes the elasticity of tool mandrel after skeleton is inserted in, and two tool mandrel sheets open and block skeleton; On the tool mandrel, and there is convex to block skeletal fixation.This structure has and connects reliably, and the advantage that skeleton is easy to loading and unloading is even skeleton has the error also can secure fixation at length direction slightly.

Wherein: 1, tool core; 2, skeleton; 3, tool mandrel; 4, elongated slot; 5, go up tool mandrel sheet; 6, following tool mandrel sheet; 7, convex.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to describe.
Fig. 1, Fig. 2, Fig. 3 are the structural representations of elastic tension formula tool; From figure, find out; It includes the tool core 1 that is connected with main shaft; Be connected with the tool mandrel 3 of socket skeleton 2 at an end of tool core 1, on tool mandrel 3, have axial elongated slot 4, tool mandrel 3 is divided into tool mandrel sheet 5 and following tool mandrel sheet 6; The length of elongated slot 4 is greater than the width B of socket skeleton 2, on last tool mandrel sheet 5 and following tool mandrel sheet 6 or the outer surface of one of them, is shaped on to prevent skeleton 2 slippages and the convex 7 of epirelief is as shown in Figure 4.
