Abstract
The utility model relates to a central spindle pulling device for machining. The device comprises a lead screw, a front end steel pipe, a support steel pipe, a back end steel pipe, an inner screw thread steel pipe and a positioning open mouth, and is characterized in that one end of the support steel pipe is welded to the front end steel pipe and the other end is welded to the back end steel pipe so a support assembly is formed; the positioning open mouth is arranged in the front end steel pipe; rotating spanners are symmetrically welded to the inner screw thread steel pipe; the lead screw penetrates the inner screw thread steel pipe and the support assembly and is fixed on a tool or a workpiece via the positioning open mouth so as to prevent the support assembly from rotating; and a screw thread is arranged on the lead screw 1. The device is advantaged by low cost, simple structure, convenient use, practicability, high working efficiency and the like.
Description
technical field:
The utility model belongs to mechanical manufacturing field, relates in particular to a kind of machining depoling shaft device.
background technology:
In mechanical processing process, particularly, in precision optical machinery processing, whether very important for crudy the accurate positioning of workpiece is, therefore needs locating shaft to locate.After welding, be used for the locating shaft of location to be but difficult to successfully extract, relatively expend man-hour, also workman's operation is made troubles simultaneously, cause inefficiency, cost high.For this reason, we have designed the device of a kind of machining depoling axle.
summary of the invention:
The purpose of this utility model is exactly in order to overcome above-mentioned shortcoming, and the device of a kind of machining rational in infrastructure, easy to use depoling axle is provided.
It is to implement like this that the utility model solves the technical scheme that its technical problem adopts: a kind of machining depoling shaft device, comprise screw mandrel, front end steel pipe, supporting steel pipe, rear end steel pipe, inner thread steel pipe, rotary spanner, locating aperture, it is characterized in that: supporting steel pipe one end welding front end steel pipe, other end welding rear end steel pipe, composition bracket assembly, is provided with locating aperture on front end steel pipe; Rotary spanner is symmetrically welded on inner thread steel pipe; Screw mandrel, through inner thread steel pipe, bracket assembly, is fixed on frock or workpiece to prevent bracket assembly rotation by locating aperture.
On described screw mandrel 1, there is screw thread.
The utlity model has that cost is low, simple in structure, convenient and practical, operating efficiency advantages of higher.
brief description of the drawings:
Fig. 1 is the cutaway view of the front view of the utility model structure.
Fig. 2 is the top view of the utility model structure.
In figure: 1. screw mandrel, 2. front end steel pipe, 3. supporting steel pipe, 4. rear end steel pipe, 5. inner thread steel pipe, 6. rotary spanner, 7. locating aperture.
detailed description of the invention:
As shown in Figure 1 and Figure 2, a kind of machining depoling shaft device, comprises screw mandrel 1, front end steel pipe 2, supporting steel pipe 3, rear end steel pipe 4, inner thread steel pipe 5, rotary spanner 6, locating aperture 7, it is characterized in that:
Supporting steel pipe 3 one end welding front end steel pipes 2, other end welding rear end steel pipe 4, composition bracket assembly, is provided with locating aperture 7 on front end steel pipe 2; Rotary spanner 6 is symmetrically welded on inner thread steel pipe 5; Screw mandrel 1, through inner thread steel pipe 5, bracket assembly, is fixed on frock or workpiece to prevent bracket assembly rotation by locating aperture 7.
On described screw mandrel 1, there is screw thread.
Embodiment: while using depoling shaft device, the other end of screw mandrel 1 is connected with mandrel thread and ensures that screw mandrel 1 does not rotate, and by locating aperture 7, support is fixed on frock or workpiece, prevents bracket assembly rotation.Rotary spanner 7 rotates inner thread steel pipe 5, and now, due to the barrier effect of support, 5 of inner thread steel pipes rotate not do and move forward and backward, and are with moving mandrel outwards to move thereby realized screw mandrel 1, finally completes extracting of mandrel in frock.
