Abstract

The invention discloses a multistage self-locking and positioning device, wherein multiple through holes are formed in the side wall of a positioning sleeve; positioning pins are arranged in the through holes; screw sleeves are fixedly installed on the outer ends of the through holes; limiting steps are arranged on the positioning pins; springs are installed in the through holes; one end of each spring is pressed against the inner end face of the corresponding screw sleeve; the other end of each spring is pressed against the left end face of the corresponding limiting step; the lower end of a drive rod stretches into a center hole in the positioning sleeve and is fixedly connected with the multistage self-locking and positioning device; the upper end of a screw rod stretches out of the positioning sleeve; a multistage cone dish (3) is provided with multiple cylindrical sections (31) and conical sections (32) at intervals, which are gradually shrunken or amplified from top to bottom or from bottom to top; the right ends of the positioning pins are provided with shafts; pulleys cooperating with the multiple cylindrical sections and conical sections are arranged on the shafts. By the adoption of the multistage self-locking and positioning device, the multistage cone dish is driven through the drive rod, so that the stretching length of each positioning pin is controlled; at the moment, various devices can be positioned quickly; moreover, when a roller moves to the cylindrical sections, the positioning pins implement automatic locking on the roller; therefore, the multistage self-locking and positioning device is flexible to operate and reliable in positioning.

Description

Multistage automatic locking positioning device
Technical field
The present invention relates to field of machining, particularly a kind of location swelling device that can realize quick location.
Background technology
Along with the development of Machining Technology, traditional scroll chuck location can not meet the process requirements of the part of configurations, and the clamping locate mode of part is a design focal point of manufacture field always.In a kind of peculiar part that need to position by hole site processing is processed, design the key that a kind of positioner that can be processed as locating surface by hole becomes processing technology.
Summary of the invention
The technical problem to be solved in the present invention has been to provide a kind of simple to operate flexible, and location is the location swelling device reliably.
For solving the problems of the technologies described above, the present invention has adopted a kind of multistage automatic locking positioning device, comprises positioning sleeve, alignment pin, multi-level cone dish, drive rod, spring and swivel nut, it is characterized in that: also comprise axle and roller; Be provided with a plurality of through holes on described positioning sleeve sidewall, in described through hole, be provided with alignment pin, described through hole outer end is installed with swivel nut, be provided with limited step on described alignment pin, described spring fitting is in through hole, and the one end withstands on the swivel nut inner face, and the other end withstands on the limited step left side; Described drive rod lower end is stretched in the positioning sleeve centre bore and is fixedly connected with the multi-level cone dish, and positioning sleeve is stretched out in the described bar of spiral shell upper end; Described multi-level cone dish is arranged at intervals with cylindrical section and conical section from top to bottom a plurality of or that dwindle gradually from the bottom to top or amplify; Described alignment pin right-hand member is provided with axle, is provided with the pulley be slidably matched with described cylindrical section and conical section on described axle.
As a further improvement on the present invention, on described positioning sleeve, the quantity of through hole is three, and described alignment pin is three.
The beneficial effect that the present invention has: the present invention is sub-packed in the through hole of decile on positioning sleeve inner chamber circumference by three alignment pins, drive the multi-level cone dish by drive rod, control the length of stretching out of alignment pin, can locate fast different devices, and, when roller moves to cylindrical section, alignment pin will automatically lock, so this device flexible operation, location is reliable, strong adaptability.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, positioning sleeve, 2, alignment pin, 3, the multi-level cone dish, 31, cylindrical section; 32, conical section; 4, drive rod, 5, axle, 6, roller, 7, spring, 8, swivel nut, 9, limited step.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Multistage automatic locking positioning device as shown in Figure 1, comprise positioning sleeve 1, alignment pin 2, multi-level cone dish 3, drive rod 4, spring 7 and swivel nut 8, it is characterized in that: also comprise axle 5 and roller 6; Be provided with a plurality of through holes on described positioning sleeve 1 sidewall, be provided with alignment pin 2 in described through hole, described through hole outer end is installed with swivel nut 8, be provided with limited step 9 on described alignment pin 2, described spring 7 is arranged in through hole, the one end withstands on swivel nut 8 inner faces, and the other end withstands on limited step 9 left sides; Described drive rod 4 lower ends are stretched in positioning sleeve 1 centre bore and are fixedly connected with multi-level cone dish 3, and positioning sleeve 1 is stretched out in the described bar of spiral shell 4 upper ends; Described multi-level cone dish 3 is arranged at intervals with cylindrical section 31 and conical section 32 from top to bottom a plurality of or that dwindle gradually from the bottom to top or amplify; Described alignment pin 2 right-hand members are provided with axle 5, are provided with the pulley 6 be slidably matched with described cylindrical section 31 and conical section 32 on described axle 5.
In the present embodiment, on described positioning sleeve 1, the quantity of through hole is three, and described alignment pin 2 is three, the also supporting increase of the axle 5 on it and roller 6.
During work, external force (as cylinder) drives drive rod 4, make multi-level cone dish 3 move down as required different distances, promoting alignment pin 2 by its conical surface outwards moves, when roller moves to different cylindrical sections 31, alignment pin 2 will be automatically locked at different extension elongations, thereby realize the fixing of positioner; While unloading positioner, external force (as cylinder) drives drive rod 4, and multi-level cone dish 3 is moved up, and moves inward under the effect of spring 7 by its alignment pin 2, thereby makes to locate swelling device and workpiece disengagement.
