Abstract
The utility model provides an internal expanding formula anchor clamps, includes the holder, is equipped with center bore on the holder, is equipped with the core that rises that is used for pressing from both sides tight work piece in the center bore, the core that rises extends to outside the holder in following center bore, that pot head that the core that rises extended to the holder outside is equipped with the tight cover that rises, and the outside cover of the tight cover that rises is equipped with and is used for the location lid that it rises to prescribe a limit to tightly overlaps the radial position, and the location lid is connected with the holder is detachable. This application is risen by tight cover through the change and is adjusted the core that rises, has saved the process of original correction jack catch, change fast, labour saving and time saving.
Description
Technical field
The application relates to mechanical clamp field, especially a kind of internal expansion type fixture.
Background technology
Oild chuck is one the most common in industrial fixture, and oild chuck is evenly distributed with movable jaw, claw moving radially along chuck, thus is fixed by workpiece.In actual use, in order to adapt to the hydraulic cylinder of different endoporus, need to change claw, and once change claw, will ensure that the gripping center of claw and chuck axle center are unified, this needs the plenty of time to remove to revise claw, wastes time and energy.
Summary of the invention
The application provides a kind of internal expansion type fixture, solves prior art and is revising the problem wasted time and energy in claw process.
According to the first aspect of the application, the application provides a kind of internal expansion type fixture, and comprise holder, holder is provided with central shaft hole, is provided with the core that rises for clamping work pieces in central shaft hole, and the core that rises extends to outside holder in central shaft hole; That one end that the core that rises extends to outside holder is arranged with expansion sleeve, and the outside of expansion sleeve is arranged with the locating cover for limiting expansion sleeve radial position, and locating cover is connected with holder is detachable.
Preferably, the core that rises that one end extended to outside holder is provided with a conical surface portion, and the radius in conical surface portion reduces successively along bearing of trend; Expansion sleeve comprises the nesting part be set in outside conical surface portion, and the inwall of nesting part and the outer surface in conical surface portion match.
Preferably, expansion sleeve also comprises an extension extended radially outward, and extension and locating cover inwall abut against.
Preferably, locating cover comprises the abutting part abutted against with nesting part.
Preferably, the surface of locating cover is provided with some screws, is provided with the screw be spirally connected with holder in screw.
The beneficial effect of the application is, the application is provided with the core that rises for clamping work pieces in the central shaft hole of holder, and the core that rises extends to outside holder in central shaft hole; That one end that the core that rises extends to outside holder is arranged with expansion sleeve, and the outside of expansion sleeve is arranged with the locating cover for limiting expansion sleeve radial position, and locating cover is connected with holder is detachable.Therefore, regulating by changing expansion sleeve the core that rises, eliminating the process of original correction claw, changing speed fast, time saving and energy saving.
Accompanying drawing explanation
Fig. 1 is the sectional view of embodiment 1;
Fig. 2 is the structural representation of embodiment 1.
Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by detailed description of the invention.
Embodiment 1:
A kind of internal expansion type fixture, as depicted in figs. 1 and 2, comprise holder 1, holder 1 is provided with central shaft hole 11, is provided with the core 2 that rises for clamping work pieces in central shaft hole 11, and the core 2 that rises extends to the outside of holder 1 in central shaft hole 11.That one end that the core 2 that rises extends to outside holder 1 is arranged with expansion sleeve 3, the outside of expansion sleeve 3 is arranged with for limiting expansion sleeve 3 at the locating cover 4 of position in core 2 radial direction that rises, the surface of locating cover 4 is provided with some screws 42, the screw be spirally connected with holder 1 is provided with in screw 42, by coordinating of screw and screw 42, locating cover 4 is fixed on holder 1 removably.When expansion sleeve 3 changed by needs, pull down locating cover 4, replace new expansion sleeve 3 and be set in and rise on core 2.The inner ring radius of expansion sleeve 3 can change the gripping radius of the core 2 that rises, thus can be used for the workpiece of gripping different radii.
Further, the core 2 that rises that one end extended to outside holder 1 is provided with a conical surface portion 21, and the radius in conical surface portion 21 reduces successively along bearing of trend.Expansion sleeve 3 comprises the nesting part 31 be set in outside conical surface portion 21, and the inwall of nesting part 31 and the outer surface in conical surface portion 21 match.Because the radius in conical surface portion 21 reduces successively along bearing of trend, be convenient to expansion sleeve 3 and be set on the core 2 that rises or from the core 2 that rises and take off.
Further, expansion sleeve 3 also comprises an extension extended radially outward 32, and extension 32 and locating cover 4 inwall abut against, and locating cover 4 comprises the abutting part 41 abutted against with nesting part 31.Therefore, extension 32 and locating cover 4 abut against, and locating cover 4 and nesting part 31 abut against, against each other by two positions, place, and locating cover 4 can limit expansion sleeve 3 position diametrically better.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made.
Claims (5)
1. an internal expansion type fixture, comprises holder, and holder is provided with central shaft hole, it is characterized in that: be provided with the core that rises for clamping work pieces in central shaft hole, and the core that rises extends to outside holder in central shaft hole; That one end that the core that rises extends to outside holder is arranged with expansion sleeve, and the outside of expansion sleeve is arranged with the locating cover for limiting expansion sleeve radial position, and locating cover is connected with holder is detachable.
2. fixture according to claim 1, is characterized in that: the core that rises that one end extended to outside holder is provided with a conical surface portion, and the radius in conical surface portion reduces successively along bearing of trend; Expansion sleeve comprises the nesting part be set in outside conical surface portion, and the inwall of nesting part and the outer surface in conical surface portion match.
