Abstract
The utility model belongs to the field of turning devices for thin-wall circular workpieces, and in particular relates to a special jig. The special jig comprises a soft claw and a hard claw fixed through a dowel. The soft claw comprises three fan-shaped jack catches. Each fan-shaped jack catch comprises a peripheral part and an inner core part. The peripheral part is located outside the inner core part and an outer gap is arranged between two adjacent peripheral parts. An inner gap communicated with the outer gap is arranged between two adjacent inner core parts. The special jig is characterized in that the gap of the inner gaps is greater than that of the outer gaps. According to the special jig provided by the utility model, the inner gaps among the fan-shaped jack catches are maximized under the premise of not reducing area of thrust surface.
Description
Technical field
The utility model belongs to the turning processing unit (plant) field of thin wall circular workpiece, relates in particular to a kind of anchor clamps.
Background technology
In thin wall circular class workpiece turning process, the most general processing mode is to adopt scroll chuck to carry out turning processing.For the bigger workpiece of some external diameters, because the contact-making surface of the relative workpiece of chuck is too small, require the operator to clamping force certain grasp will be arranged usually, but relatively more difficult in the practice process.Clamping force is excessive may to cause the workpiece unbalance stress to cause clamping distortion, and clamping force is too small may to be caused in the turning process workpiece to fly out causing security incident.
Lifting surface area increases the used scroll chuck of this workshop section in that clamping force is constant and then the suffered pressure of minimizing workpiece makes workpiece not produce deformation " fan-shaped claw " as far as possible at present.Be provided with outer crack between the adjacent peripheral part of fan-shaped claw, be provided with the inner width that connects with outer crack between the adjacent inner core, the gap of outer crack and inner width is identical.In reality is produced in batches, because thereby the too small easy card smear metal of inner width produces following shortcoming: for cleaning aluminium bits waste time more, it is defective that cleaning thoroughly can not produce shape, the lathe tool rust can make chip volume become big, yet lathe tool does not fully use and just carries out high-frequency tool changing, has a strong impact on the working (machining) efficiency of workpiece.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of special fixture, comprise soft pawl and hard pawl, described soft pawl and described hard pawl are fixed by pin, described soft pawl comprises 3 fan-shaped claws, described fan-shaped claw comprises peripheral part and inner core, crack outside described peripheral part is provided with between the outside and adjacent described peripheral part of described inner core, be provided with the inner width that connects with described outer crack between the adjacent described inner core, it is characterized in that: the gap of described inner width is greater than the gap in described outer crack.
The beneficial effects of the utility model are: the gap of inner width is greater than the gap in described outer crack in the utility model, increased the gap of fan-shaped claw inner width, guaranteed in the inner width maximization that makes under the prerequisite that does not reduce lifting surface area between the fan-shaped claw, thereby solved the problem that wastes time, produces defective work, high-frequency replacing blade that is produced by card aluminium bits; Adopt pin to connect between soft pawl and the hard pawl, the soft pawl under the different materials better is connected and the location with hard pawl.The utility model makes the inner width between the fan-shaped claw reach maximization under the prerequisite that does not reduce lifting surface area.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Among the figure, the soft pawl of 1-, the hard pawl of 2-, 3-pin, the fan-shaped claw of 4-, the outer crack of 5-, 6-peripheral part, 7-inner core, 8-inner width, 9-screw, 10-main shaft.
Shown in Fig. 1-2, soft pawl 1 and hard pawl 2 are fixing by pin 3, soft pawl 1 comprises 3 fan-shaped claws 4, fan-shaped claw 4 comprises peripheral part 6 and inner core 7, crack 5 outside peripheral part 6 is provided with between the outside and adjacent peripheral part 6 of inner core 7, be provided with the inner width 8 that connects with outer crack 5 between the adjacent inner core 7, the gap of inner width 8 is greater than the gap in outer crack 5.
As shown in Figure 3-4, soft pawl 1 and hard pawl 2 are fixing by pin 3, soft pawl 1 comprises 3 fan-shaped claws 4, fan-shaped claw 4 comprises peripheral part 6 and inner core 7, crack 5 outside peripheral part 6 is provided with between the outside and adjacent peripheral part 6 of inner core 7, be provided with the inner width 8 that connects with outer crack 5 between the adjacent inner core 7, the gap of inner width 8 is greater than the gap in outer crack 5.
Shown in Fig. 5-6, soft pawl 1 and hard pawl 2 are fixing by pin 3, soft pawl 1 comprises 3 fan-shaped claws 4, fan-shaped claw 4 comprises peripheral part 6 and inner core 7, crack 5 outside peripheral part 6 is provided with between the outside and adjacent peripheral part 6 of inner core 7, be provided with the inner width 8 that connects with outer crack 5 between the adjacent inner core 7, the gap of inner width 8 is greater than the gap in outer crack 5.
Make use-case
As shown in Figure 7, the installation steps of the special fixture in the utility model and lathe are as follows:
Utilize pin 3 to make soft pawl 1 and hard pawl 2 position and link, with suitable screw 9 special fixture is connected with the main shaft 10 of lathe then, adjust the gap in inner width 8 and outer crack 5 with hard pawl 2 and the tooth on the main shaft 10.
More than 3 embodiment of the present utility model are had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
