Abstract

The utility model relates to a clamping means for securing work-piece during machine processing, particularly a clamping means which is suitable to be used for processing an end shaft whose one end forms steps. The utility model comprises a clamping body 1 and fastening screws 3. The utility model is characterized in that the inner surface 3 of the clamping body 1 forms holes d 1 and d 2 with steps; a run off part 4 with a beta angle is arranged between the step hole d 2 and d 1.

Description

A kind of machining clip

The utility model relates to a kind of machining clip, and being specially adapted to an end is the end axle processing clip of step.

Clip (also claiming dop) is in the machining, especially a kind of clamping device of extensive use in cylindricalo grinding and turning.Its effect is to drive workpiece (for example axle) rotation.Hoop sleeve is at workpiece one end during use, and fastening with screw, be installed in then two top between, start headstock dial, stir clip, drive the workpiece rotation, thereby realize grinding or turning processing.

Clip commonly used is by circular chuck, heart carrier and two square clamps (seeing accompanying drawing 1, Fig. 2, Fig. 3) that vee-block is formed, and the clamping state was seen accompanying drawing 4 during it used.The thickness of this type of clip is at 12-20mm.Therefore, when the wide stage axle of clamping 4-20mm, because working method as shown in Figure 5, in process, grinding head grinding wheel 6 can't be ground to the root A place of stage axle 7.So need in the false add worker, car goes out clamping technology axle in advance, just can carry out grinding.After treating that external diameter all machines, remove technology shaft portion B again.Make the workpiece cutting length to increase like this, promptly the expense material is taken a lot of work again, and operating efficiency is not high yet.

The purpose of this utility model just is to provide a kind of end end shaft mechanical processing with the level clip that is applicable to, with overcome that prior art exists can't the whole external diameters of grinding band stage axle (or cylindrical) shortcoming, original technology of promptly taking a lot of work and taking material, to increase work efficiency, economical with materials reduces production costs.

The purpose of this utility model is realized by following technical scheme:

A kind of machine clip, be particularly useful for machining one end end axle with the level clip, it comprises clip body 1 and trip bolt 2, it is characterized in that the inner surface 3 on the clip body 1 is d1 with the level, d2, and has the escape 4 at band β angle between stepped hole d2 and d1.

The purpose of this utility model can also further be realized by following technical measures:

Aforesaid clip, the inner surface 3 of band stepped hole leaves the surface 5 that a width b is 1-3mm between its stepped hole d2 and the d1.

Aforesaid clip, angle β=30 of its escape 4 °-60 °

Aforesaid clip, its escape 4 is a straight trough.

The utility model has the advantages that: simple for structure, only need on the clip body, to process the band stepped hole, and the escape with certain angle β gets final product, promptly having solved in shortcoming that present technology can't process and the processing promptly the expense material takes a lot of work again, inefficient shortcoming, improve stock utilization again, reduced production cost.

Below in conjunction with Figure of description and embodiment the utility model is further described.

Embodiment:

Fig. 7 is one of embodiment of the present utility model.It is to be provided with stepped hole d1 and d2 on the inner surface 3 of clip body 1, and has escape 4 between hole d2 and the d1, and the form of groove 4 is for having angle beta, β=30 °-60 ° or be straight trough.Leave the surface 5 of certain width b between d2 and d1.b=1-3mm。

The β of present embodiment=60 ° b=1.5mm, the clip body is provided with trip bolt 2.

Claims

1, a kind of machining clip, being specially adapted to an end is the end axle processing clip of step, it comprises clip body (1) and trip bolt (2), the inner surface (3) that it is characterized in that clip body (1) is hole d1 with the level, d2, and is provided with the escape (4) at band β angle between stepped hole d2 and d1.

2, clip according to claim 1 is characterized in that leaving the surface (5) that a width b is 1-3mm between inner surface (3) its stepped hole d2 with stepped hole and the d1.

3, clip according to claim 1 is characterized in that angle β=30 °-60 ° of escape (4)

4, clip according to claim 1 is characterized in that escape (4) is a straight trough.
