Background technique
The defect that existing screw thread amplifier exists due to design, causes the screw rod in screw thread amplifier doing in linear reciprocating motion process, in internal thread mould, screw thread fall back and the initial position of screw thread and final position cannot the problems of determinacy and a putting property; Next is that there is certain error, validity is not high because screw rod is coarse thread trapezoidal thread.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of and reduce error, guarantees the determinacy of position in working procedure and conforming screw thread amplifier.
The purpose of this utility model has been come by following technical solution, this screw thread amplifier, comprises fixing frame and screw rod, and the two ends of described screw rod are overlapped respectively and had screw sleeve, screw sleeve is spacing to be fixed in screw sleeve positioning ring, and screw sleeve positioning ring is fixed on fixing frame; Be connected with nut with the described screw rod relation of being threaded, this nut is fixedly connected with rotating sprocket, is connected between this rotating sprocket with power input sprocket by chain, and this nut, rotating sprocket and power input sprocket are all positioned at the groove that fixing frame is offered; What be connected with described power input sprocket also has product stripping power input sprocket, and power input sprocket and product stripping power input sprocket are connected with oil motor and provide power by oil motor, and this oil motor is fixed on the side of fixing frame by oil motor fixed base; Be provided with the dog link rotated for preventing screw rod in the side of described screw rod, this dog link is fixed on relay stand.
As preferably, the described limit relay being positioned at screw rod both sides is fixed on limit relay seat, and be connected and fixed in slideway type between this limit relay seat and relay stand, relay stand is fixed on the bottom of fixing frame.
As preferably, described limit relay seat adds the adjustable screw for regulating limit relay, this adjustable screw is connected with adjustable screw fixed base, and adjustable screw fixed base is fixed on the side of relay stand.
The beneficial effects of the utility model are: screw rod two ends install the displacement distance that limit relay is conducive to controlling screw rod additional, guarantee determinacy and the conformity of the initial position of screw thread on plastic; By installing the adjustable screw error solved existing for screw motion additional.
Accompanying drawing explanation
Fig. 1 is exploded isometric structural representation of the present utility model.
Fig. 2 is main TV structure schematic diagram of the present utility model.
Label in accompanying drawing is respectively: 1, screw rod; 2, rotating sprocket; 3, power input sprocket; 4, chain; 5, fixing frame; 6, relay stand; 7, limit relay; 8, adjustable screw; 9, oil motor; 10, dog link; 11, nut; 12, screw sleeve; 13, limit relay seat; 14, screw sleeve positioning ring; 15, adjustable screw fixed base; 16, oil motor fixed base; 17, product stripping power input sprocket; 51, groove.
Embodiment
Below in conjunction with accompanying drawing, detailed introduction is done to the utility model: as shown in accompanying drawing 1,2, the utility model comprises fixing frame 5 and screw rod 1, the two ends of described screw rod 1 are overlapped respectively and are had screw sleeve 12, screw sleeve 12 is spacing to be fixed in screw sleeve positioning ring 14, and screw sleeve positioning ring 14 is fixed on fixing frame 5; Nut 11 is connected with described screw rod 1 relation of being threaded, this nut 11 is fixedly connected with rotating sprocket 2, be connected by chain 4 between this rotating sprocket 2 with power input sprocket 3, this nut 11, rotating sprocket 2 and power input sprocket 3 are all positioned at the groove 51 that fixing frame 5 is offered; What be connected with described power input sprocket 3 also has product stripping power input sprocket 17, power input sprocket 3 and product stripping power input sprocket 17 are connected with oil motor 9 and provide power by oil motor 9, power input sprocket 3 is driven by the initial driving force of oil motor 9, rotating sprocket 2 and the inside nut 11 is driven by chain 4, nut 11 original position that rotating sprocket is 2 li rotates, and screw rod 1 does not turn the Der Grundsatz der Maschinen only doing linear reciprocating motion.This oil motor 9 is fixed on the side of fixing frame 5 by oil motor fixed base 16; Be provided with the dog link 10 rotated for preventing screw rod in the side of described screw rod 1, this dog link 10 is fixed on relay stand 6.
The described limit relay 7 being positioned at screw rod 1 both sides is fixed on limit relay seat 13, and be connected and fixed in slideway type between this limit relay seat 13 and relay stand 6, relay stand 6 is fixed on the bottom of fixing frame 5; Add that at screw rod 1 two ends limit relay 7 is to control the displacement distance of screw rod 1, under certain velocity ratio, thus the determinacy of the initial position of screw thread and a putting property on guarantee plastic, thus solve oil motor 9 in internal thread mould, screw thread fall back and the initial position of screw thread and final position cannot the problems of determinacy and a putting property.
Described limit relay seat 13 adds the adjustable screw 8 for regulating limit relay, this adjustable screw 8 is connected with adjustable screw fixed base 15, and adjustable screw fixed base 15 is fixed on the side of relay stand 6; Because screw rod 1 is coarse thread trapezoidal thread, there is certain error, add an adjustable screw 8 below to regulate the position of limit relay 7 at two limit relays 7, solve the error brought.
The utility model is not limited to above-mentioned mode of execution; no matter do any change on its shape or material are formed; every employing structural design provided by the utility model, is all one distortion of the present utility model, all should thinks within the utility model protection domain.
