Description
Technical field
The invention belongs to the technical field of piece-holder.
Background technology
Interior clamping device is a kind of mechanism realizing being carried out by inside workpiece clamping, and because the requirement of some workpiece to outer surface is higher or need to process the outer surface of workpiece, therefore can only adopt interior clamping.
Existing interior clamping device usually only carries out interior clamping to a point, under the effect of external force, although being not easily moved of workpiece, but easily rotate along hole or groove, cause Workpiece fixing inaccurate, man-hour is being added to outer surface of workpiece, also easily do not reach the requirement of design.
Summary of the invention
The invention provides a kind of interior clamping device with shell fragment, usually only carry out interior clamping to a point to solve existing interior clamping device, under the effect of external force, workpiece easily carries out the problem of rotating along hole or groove.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: a kind of interior clamping device with shell fragment, comprise base, clamping bar, adjustable ring, pole, be arranged on fixed station on base and one end and be fixed on hydraulic stem on base, the quantity of clamping bar is two, two clamping bars are all hinged on base, the quantity of fixed station is four, be located at the both sides of clamping bar respectively, through there being adjusting bolt on fixed station, adjusting bolt offsets with the side of clamping bar respectively, the side of clamping bar is provided with shell fragment, adjustable ring passes clamping bar and is positioned at the below of shell fragment, one end of pole is connected with shell fragment, the other end is connected with adjustable ring, the other end and the adjustable ring of hydraulic cylinder offset.
Principle of the present invention is: first turn adjusting bolt, by adjusting bolt, clamping bar is located in place, make the hole of clamping bar and workpiece or groove corresponding.Be enclosed within clamping bar by the hole of workpiece or groove again, adjustable ring is driven by hydraulic stem, the rising of adjustable ring and decline, controls the opening and closing of shell fragment on clamping bar.When shell fragment is in open configuration, clamping bar can by Workpiece clamping, and when shell fragment is in closure state, clamping bar by Workpiece clamping, but can not be in the state of unclamping, and can conveniently be unloaded from clamping bar by workpiece.
Compared with prior art, the invention has the advantages that: 1, the position of clamping bar is adjustable, can regulate according to the difference of relative position between workpiece holes or groove, can realize clamping in workpiece two points, workpiece was both not easily moved, also not easily rotate along hole, man-hour is being added to outer surface of workpiece, be convenient to location.2, control the clamping of workpiece by hydraulic stem and unclamp, can be used for hole or the groove of different size on clamping work pieces.
Further, described shell fragment is coated with rubber layer, reduces the inwall of shell fragment to hole on workpiece or groove and damage.
Further, the shell fragment that a clamping bar is arranged is at least two, the inwall of workpiece hole or groove is all contacted with shell fragment, and does not directly contact with clamping bar, because shell fragment has elasticity, the end of shell fragment can fully with the contact internal walls of workpiece hole or groove.
Further, the inwall of described adjustable ring is provided with roller, is Structure deformation between the inwall of adjustable ring and clamping bar, and make frictional force between the inwall of adjustable ring and clamping bar less, the wearing and tearing of adjustable ring and clamping bar are less.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
Fig. 1 is the structural representation of the interior clamping mechanism embodiment of band shell fragment of the present invention.
Detailed description of the invention
Reference numeral in Figure of description comprises: base 1, clamping bar 2, adjustable ring 3, pole 4, fixed station 5, hydraulic stem 6, shell fragment 7, adjusting bolt 8.
As shown in Figure 1, a kind of interior clamping device with shell fragment in the present embodiment, comprises base 1, clamping bar 2, adjustable ring 3, pole 4, is arranged on fixed station 5 on base 1 and one end and is fixed on hydraulic stem 6 on base 1.The quantity of clamping bar 2 is two, and two clamping bars 2 are all hinged on base 1, and the quantity of fixed station 5 is four, and corresponding two fixed station of clamping bar 25, two fixed stations 5 are located at the relative both sides of clamping bar 2.Through there being an adjusting bolt 8 on a fixed station 5, therefore corresponding two adjusting bolts 8 of clamping bar 2, adjusting bolt 8 offsets with the side of clamping bar 2 respectively, and two adjusting bolts 8 on a clamping bar 2 are 180 degree, intervals along corresponding clamping bar 2.The side of clamping bar 2 is provided with shell fragment 7, and the length of shell fragment 7 is greater than the length of side of hole or groove radius or 1/2nd, and the shell fragment 7 that a clamping bar 2 is arranged is at least two.Adjustable ring 3 is through clamping bar 2 and be positioned at the below of shell fragment 7, and the upper end of pole 4 is connected with shell fragment 7, and lower end is connected with adjustable ring 3 (adjustable ring 3, be similar to the structure opened an umbrella between pole 4 and shell fragment 7).The other end and the adjustable ring 3 of hydraulic cylinder offset, and the inwall of adjustable ring 3 is provided with roller.
In use, the adjusting bolt 8 of turn clamping bar 2 both sides, because clamping bar 2 and adjusting bolt 8 offset, therefore can position the clamping bar 2 of rotary state the present embodiment, makes two clamping bars 2 can simultaneously through the hole on workpiece or groove.Be enclosed within clamping bar 2 by the hole of workpiece or groove again, regulator solution depression bar 6, hydraulic stem 6 is extended, and adjustable ring 3 also can raise, and adjustable ring 3 promotes pole 4 and opens, and pole 4 is with spring plate 7 to open, until held out against in the hole of workpiece or groove.When needs unload workpiece, regulator solution depression bar 6, hydraulic stem 6 is shunk, and adjustable ring 3 also can reduce, and adjustable ring 3 promotes pole 4 closing, and pole 4 is with spring plate 7 to close, and when the contact internal walls of shell fragment 7 not with the groove of workpiece and hole, workpiece just can unload like a cork.
Shell fragment 7 is coated with rubber layer, and the inwall reducing hole or groove on shell fragment 7 pairs of workpiece damages.The shell fragment 7 that a clamping bar 2 is arranged is at least two, the inwall of workpiece hole or groove is all contacted with shell fragment 7, and does not directly contact with clamping bar 2, because shell fragment 7 has elasticity, no matter the shape of workpiece hole or groove is circular or square, the end of shell fragment 7 all can fully with the contact internal walls of workpiece hole or groove.The inwall of described adjustable ring 3 is provided with roller, is Structure deformation between the inwall of adjustable ring 3 and clamping bar 2, and make frictional force between the inwall of adjustable ring 3 and clamping bar 2 less, the wearing and tearing of adjustable ring 3 and clamping bar 2 are less, can use chronically.Two adjusting bolts 8 are 180 degree, the intervals (that is to say as being oppositely arranged) along corresponding clamping bar 2, being the stress balances in order to make clamping bar 2, making the state that clamping bar 2 keeps stable.
For a person skilled in the art, under the prerequisite not departing from structure of the present invention, can also make some distortion and improvement, these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
