Abstract
The utility model relates to a stretching support device, which comprises a fixing outer sleeve, a support arm, a support wheel and a hydraulic cylinder, wherein, the middle part of the support arm is matched in a rotary mode with a pin post which can axially move in the fixing outer sleeve; the rear end of the support arm is connected with a piston rod of the hydraulic cylinder through a self-adaptive and locking mechanism; the rear end of the cylinder body of the hydraulic cylinder is hinged with a fixed support seat. The utility model can successively and respectively support a plurality of supported objects of curved surface bodies on the same position in a self-adaptive mode, and can automatically lock.
Description
The utility model relates to a kind of mechanical support member, particularly a kind of telescopic support device.
In mechanical device, needs according to production technology, often need to use a kind of flexible supporting member, successively support a plurality of supported objects respectively at same position, when especially the geometrical shape of supported object was curved surface such as cylindrical body, flexible supporting member was to adopt retractable support arm top that two supporting wheels are installed.When having two reels to rotate to the support arm position on the coiling machine as milling train, support by flexible support arm with deep bid.Though existing support arm is simple in structure, but rigidity is big, the position that two reels rotate to support arm differs 1～2mm respectively, the support arm that then existing rigidity is big two reels of just can not fitting well play a supportive role, and to force supported object to adapt to the position of support arm, very unfavorable to the work of coiling machine.
The purpose of this utility model is to provide a kind of improved telescopic support device, has self adaption and lock function, and can same position successively respectively self adaption support a plurality of curved surface supported objects, and can automatically lock.
For achieving the above object, the utility model adopts following technical proposals:
A kind of telescopic support device, comprise fixed jacket, support arm, supporting wheel and oil hydraulic cylinder, it is characterized in that support arm middle part and an energy axially displaced pin in fixed jacket is rotatably assorted, the support arm rear end is connected with the piston rod of oil hydraulic cylinder with locking framework by self adaption, and hydraulic cylinder body rear end and fixed bearing are hinged.
The above-mentioned self adaption and the structure of locking framework can be designed to: support arm rearward end and two friction posts are rotatably assorted, two wiping posts are by two stage clips and bolt and nut and piece is carved in one of clamping, there are ball recess and a bulb coupling in the rear end of carving piece, fixedly connected with the piston rod of oil hydraulic cylinder in the bulb rear end, there is friction board at the place, outer end of friction post.
Above-mentioned support arm is rotatably assorted by two linings and two friction posts.
Above-mentioned pin two ends are rotatably assorted by lining and two guide sleeves, and two guide sleeves cooperate with two guide plate slides with guide groove respectively.
In the said fixing overcoat stationary bushing is arranged, stationary bushing and friction board and guide plate be drive fit fixedly.
The utility model compared with prior art, have following conspicuous characteristics and advantage: the self adaption and the locking framework that have adopted support arm in the utility model, thereby can same position successively respectively self adaption support a plurality of curved surface supported objects, and can automatically lock.
The drawing of accompanying drawing is described as follows:
Fig. 1 is an embodiment's of the utility model a structural representation.
Fig. 2 is the sectional view at A-A place among Fig. 1.
An optimum implementation of the present utility model is: referring to Fig. 1 and Fig. 2, this telescopic support device includes fixed jacket 8, support arm 2, supporting wheel 1 and oil hydraulic cylinder 17, support arm 2 middle parts and an energy axially displaced pin 4 in fixed jacket 8 are rotatably assorted, the rear end of support arm is connected with the piston rod 16 of oil hydraulic cylinder 17 with locking framework by self adaption, and oil hydraulic cylinder 17 rear end of the cylinder block and fixed bearing 18 are hinged.The structure of self adaption and locking framework is: support arm 2 rearward end and two friction posts 11 are rotatably assorted, two friction posts 11 are by two stage clips 13 and bolt and nut 12 and piece 14 is carved in one of clamping, there are ball recess and bulb 15 couplings in the rear end of carving piece 14, fixedly connected with the piston rod 16 of oil hydraulic cylinder 17 in bulb 15 rear ends, there is friction board 9 at the place, outer end of friction post 11.Support arm 2 is rotatably assorted by two linings 10 and two friction posts 11.Pin 4 two ends are rotatably assorted by lining 5 and two guide sleeves 3, and two guide sleeves 3 are slidingly matched with two guide plates 6 with guide groove respectively.Stationary bushing 7 is arranged in the fixed jacket 8, and stationary bushing 7 and friction board 9 and guide plate 7 be drive fit fixedly.
Its working principle is: (one) telescopic support device is in holding state: stage clip 13 is under the effect of bolt and nut 12, the post 11 that will rub pushes carve piece 14 to, make between friction post 11 and the friction board 9 gap to occur, support arm 2 has a rotary freedom around pin 4, and supporting wheel 1 is in holding state.(2) release action: when piston rod 16 has thrust vertically (thrust is setting value), since friction post 11 with carve frictional resistance between the piece 14, friction post 11 promotion support arms 2, pin 4, guide sleeve 3 and supporting wheel 1 are moved as straight line along the guide groove in the guide plate 6.(3) self adaption action: in the supporting wheel 1 a certain take turns elder generation and supported object paste with, at this moment piston rod 16 continues to promote forward, force support arm 2 around pin 4 rotation (being with friction post 11), up to two supporting wheels 1 all paste with supported object and, support arm 2 relative stop motions.(4) lock out action: resistance is still less than the thrust of setting at this moment, and piston rod 16 continues to promote friction posts 11 and travels forward, and stage clip 13 pressurizeds make the post 11 that rubs be adjacent to friction board 9.When thrust was equal fully with resistance, motion stopped, whole device locking.(5) return action: piston rod 16 retreats, stage clip 13 decrements at first discharge, friction post 11 leaves friction board 9 and is being with support arm 2, pin 4, guide sleeve 3 and supporting wheel 1 to draw back with carving piece 14 together, and supporting wheel 1 leaves supported object, comes back to holding state.
