Abstract
The invention belongs to the field of assembling clamps for cylindrical parts, and particularly discloses a clamp for the cylindrical parts. The clamp comprises a tile-shaped clamping plate, and further comprises a protection shell, a pushing block, transmission units and a driving gear; a through hole for the pushing block to move is formed in the protection shell, the pushing block is fixed to a rack, and a clamping plate is fixed to the pushing block and located outside the protection shell; each transmission unit comprises a driven gear, a first gear and a rack, wherein the driven gear and the first gear are coaxially arranged, and the first gear and the rack are meshed; and the transmission units are distributed along the circumference of the driving gear, and the driving gears and the driven gears are meshed. As the driven gears in all transmission units are meshed with the driving gears, when the driving gears rotate, all driven gears can be driven to rotate, and finally all clamping plates are driven to move, so that the aim that the clamping plates move at the same time is achieved, synchronization of the clamping plates is achieved, and the clamping effect is guaranteed.
Description
Technical field
The invention belongs to column assembling jig field, particularly relate to a kind of fixture for column.
Background technology
Column is part conventional in machine-building.Man-hour is added to cylinder, must grip it, to ensure its precision machining.Notification number is the patent of CN204248720U, disclose a kind of centring pneumatic fixture for column, comprise base, described base is square platy structure, the middle part of described base is provided with the circular groove for place work piece, the center of described circular groove is provided with alignment pin, the midpoint of the four edges of described base is provided with Pneumatic clamping mechanism, described Pneumatic clamping mechanism comprises cylinder, the piston rod of described cylinder is provided with the clamping plate of tile-type, the clamping face of described clamping plate is just to described circular groove.Although this patent can realize the clamping of column; but; during each clamping work pieces, all need four clamping devices to drive toward middle part, after machining simultaneously; also must four clamping devices be removed simultaneously; and in actual mechanical process, owing to being that it adopts hydraulic cylinder to control each clamping device, each Pneumatic clamping mechanism often can be caused asynchronous; cause clamping plate asynchronous, thus cause the effect of clamping bad.
So, be badly in need of a kind of column fixture of clamping plate energy synchronous clamping.
Summary of the invention
Object of the present invention is providing a kind of column fixture of clamping plate energy synchronous clamping.
In order to achieve the above object, base case of the present invention is: a kind of fixture for column, comprise the clamping plate of watt shape, wherein, also comprise containment vessel, pushing block, gear unit and driving gear, described containment vessel is provided with the through hole for pushing block movement, described pushing block is fixed on tooth bar, described Boards wall is on pushing block, and be positioned at the outside of containment vessel, described gear unit comprises driven gear, first gear and tooth bar, described driven gear and the first gear are coaxially arranged, described first gear and tooth bar engage each other, described gear unit is along driving gear circle distribution, and driving gear is meshed with driven pulley, described driving wheel is provided with turning handle.
The principle of this base case is: the clamping plate of multiple watts of shapes can form an annulus, thus column are clamped.Driving gear rotates, and drives driven pulley to rotate, because driven pulley and the first gear are coaxial, so driven pulley drives the first pinion rotation.First wheel and rack engagement, then the first gear driving rack moves up and down.Pushing block is fixed on tooth bar, then pushing block drives clamping plate to move up and down, thus has driven each clamping plate to move, and finally reaches the clamping of column and unclamps.
The beneficial effect of this base case is: due to the even driving gear engagement of the driven pulley in each gear unit, when driving gear rotates, each driven pulley can be driven to rotate, each clamping plate of final driving move, reach the object of clamping plate movement simultaneously, each clamping plate are formed synchronously, ensure that the effect of clamping.
Scheme two: based on this, scheme is preferred, the external diameter of described first gear is less than the external diameter of driven pulley.When the external diameter of the first gear is greater than driven pulley, easily cause the interference between each gear, meanwhile, the excessive installation being also not easy to gear of the first gear.
Scheme three: based on this, scheme is preferred, also comprises servomotor, and described driving gear is connected with the output of servomotor.Drive driving gear to rotate by servomotor, accurately can control the rotational angle of driving gear, controllability is stronger.
Scheme four: based on this, scheme is preferred, the quantity of described gear unit is 5, and under normal circumstances, the quantity of clamping plate is all set to odd number, and clamping effect is better.The quantity of clamping plate and the quantity of gear unit relative to, compared to 3 clamping plate, 5 more, clamping effect is better.When the quantity of clamping plate is greater than 5, cost can be strengthened again.

Fig. 1 is the structural representation of the present invention for the fixture embodiment of column;
Fig. 2 is the structural representation of Fig. 1 middle gear engagement place;
Fig. 3 is the front view of Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: containment vessel 110, the output shaft 120 of servomotor, driving gear 130, the first gear 140, tooth bar 150, clamping plate 160, pushing block 170, driven pulley 180.
As shown in Figure 1, Figure 3, a kind of fixture for column, comprises containment vessel 110, servomotor, driving gear 130, first gear 140, tooth bar 150, clamping plate 160, pushing block 170 and driven gear 180.Containment vessel 110 is provided with strip groove, and pushing block 170 can slide in strip groove.Clamping plate 160 are welded on pushing block 170, and clamping plate 160 are the clamping plate 160 of watt shape, and the quantity of clamping plate 160 is five, when five clamping plate 160 draw in, and can by column fixture.
The output shaft 120 of servomotor is arranged on driving gear 130, and driving gear 130 is meshed with driven gear 180, and driven gear 180 and the first gear 140 are coaxially installed, and the first gear 140 engages each other with tooth bar 150.Driven gear 180, first gear 140 and tooth bar 150 form gear unit, and the quantity of gear unit is five, and gear unit is along driving wheel 130 circle distribution, and the driven gear 180 in gear unit all engages each other with driving gear 130.As shown in Figure 2, the external diameter of driven gear 180 is three times of the first gear 140 external diameter.
During specific works, as shown in Figure 2, driven by servomotor driving wheel 130 rotates counterclockwise, then driven gear 180 rotates clockwise, and drives the first gear 140 to rotate clockwise, thus drives tooth bar 150 to move down, final drive clamping plate 160 moved down, and column were clamped.When column is unclamped by needs, control servomotor and rotate clockwise.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; 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.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
