Send device.
Background technology
Track-mounted conveying device is common conveying equipment on automatic production line, and existing track-mounted conveying device includes
Drive sprocket, driven sprocket, chain, track (shoe) and speed reducer, the track (shoe) are connected on chain, and chain ring is around drive sprocket
And driven sprocket, drive sprocket are driven by speed reducer.When in use, workpiece is directly placed on track (shoe), using track (shoe) with
Frictional force between workpiece drives workpiece motion s, in order to carry the weight of workpiece, while chain-driving track (shoe) can again moved,
Requiring chain has larger tension, and the power of corresponding speed reducer also requires larger, and energy consumption is larger, the difficult processing of each component
Degree is big and matching requirements are also higher.
The content of the invention
In order to solve that the power of existing track-mounted conveying device speed reducer is larger and the difficulty of processing of each component greatly and
The problem of matching requirements are higher, the present invention provide a kind of track-mounted work transfer device for assembly line, this is used for assembly line
Track-mounted work transfer device be provided with the trolley that is servo-actuated with track (shoe), reduce the power of speed reducer, reduce each component
Difficulty of processing and matching requirements.
The technical scheme is that:This is used for the track-mounted work transfer device of assembly line, including drive sprocket, driven
Sprocket wheel, chain, track (shoe) and speed reducer, the track (shoe) are connected on chain, and chain ring drives around drive sprocket and driven sprocket
Movable sprocket is driven by speed reducer, is connected with trolley on the track (shoe), and the trolley includes car body, be equipped with below car body bracket and
With there are two the axle of wheel, two wheels are located on the track of track (shoe) both sides;Bracket is connected to the upper end of bracket connecting pin
And can opposing brackets connecting pin be freely rotated, bracket be equipped with bar-shaped trough, bracket connecting pin can be with respect to bar-shaped trough play, vehicle
Body is connected on axle connecting pin, and axle connecting pin is equipped with square shaft section and circular shaft section, and square shaft section is adapted with axle, and car body connects
Circular shaft Duan Bingneng is met to rotate relative to circular shaft section.
Workpiece revolution driving cylinder and revolving platform are installed, revolving platform is located at gear-box on axle above the car body
Side, revolving platform are connected by rotating shaft with the gear in gear-box, and wheel and rack is meshed, rack and workpiece revolution driving gas
The piston rod of cylinder is connected.
The present invention has the advantages that:Due to taking above-mentioned technical proposal, there is provided the trolley being servo-actuated with track (shoe),
Workpiece is placed on trolley, is carried workpiece weight by trolley and is transferred to most of gravity on track by wheel, track branch
The weight of trolley and workpiece has been supportted, has reduced the light load of the pressure to track (shoe) and chain, track (shoe) and chain, it will be original
By frictional force drive workpiece become promote moving of car rolling friction, reduce the power of speed reducer, save the energy,
Also reduce difficulty of processing and the matching requirements of each component.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings:
As shown in Fig. 1~Fig. 3, this is used for the track-mounted work transfer device of assembly line, including drive sprocket 1, driven chain
Wheel 2, chain 3, track (shoe) 4 and speed reducer 5, the track (shoe) 4 are connected on chain 3, and chain 3 is around drive sprocket 1 and driven
Sprocket wheel 2, drive sprocket 1 are driven by speed reducer 5, and trolley 6 is connected on the track (shoe) 4, and the trolley 6 includes car body 7, car body
7 lower sections are equipped with the axle 10 of bracket 8 and band there are two wheel 9, and two wheels 9 are located on the track 11 of 4 both sides of track (shoe);Bracket
8 be connected to the upper end of bracket connecting pin 12 and can opposing brackets connecting pin 12 be freely rotated, bracket 8 be equipped with bar-shaped trough 22,
Bracket connecting pin 12 can be connected to respect to 22 play of bar-shaped trough, car body 7 on axle connecting pin 13, and axle connecting pin 13 is equipped with
Square shaft section 14 and circular shaft section 15, square shaft section 14 are adapted with axle 10, and car body 7 connects circular shaft section 15 and can opposite 15 turns of circular shaft section
It is dynamic.Due to taking above-mentioned technical proposal, there is provided the trolleies 6 being servo-actuated with track (shoe) 4, and workpiece is placed on trolley 6, by trolley 6
Most of gravity is simultaneously transferred to by wheel 9 on track 11 by carrying workpiece weight, and track 11 supports the weight of trolley 6 and workpiece
Amount reduces the light load of the pressure to track (shoe) 23 and chain 22, track (shoe) 23 and chain 22, by original by friction
Power drives workpiece to become the rolling friction that trolley 6 is promoted to move, and reduces the power of speed reducer 5, saves the energy, also reduces
The difficulty of processing of each component and matching requirements.
7 top of car body is equipped with workpiece revolution driving cylinder 16 and revolving platform 17, revolving platform 17 and gear-box 19
Above axle 10, revolving platform 17 is connected by rotating shaft 18 with the gear 20 in gear-box 19, and gear 20 is nibbled with 21 phase of rack
It closes, rack 21 is connected with the piston rod of workpiece revolution driving cylinder 16.To there is the workpiece of rotation requirement to provide power drive, work
The work of part revolution driving cylinder 16 can make 17 reciprocating rotation of revolving platform, and the technological requirements such as can adapt to paint, toast, detect.
