Description
Technical field
The utility model relates to a kind of dragging trolley more particularly to a kind of Pneumatic extension dragging trolley.
Background technique
For plates of automobile punching production material by expecting rack-mounted fortune, material rack trolley passes through cylinder by the dilatory exchange of cylinder
The eave tile of front end, which pulls, is dragged to material frame using on position, and cylinder rod has deformation under the action of long-term, and eave tile endurance is big
Desoldering phenomenon can be generated, cause production line can not normal use, maintenance mans' duration.
Therefore existing apparatus has the disadvantage in that
1, pneumatic cylinder actuation is not sufficiently stable, and having the deformation of cylinder chain extension bar often can not actuation；
2, the thin operation endurance of cylinder front-end hook is big, has desoldering often and falls the phenomenon that not being available, maintenance mans
Duration, brings constant to production, and production efficiency is low.
Utility model content
In order to solve the above-mentioned technical problem, the utility model provides a kind of Pneumatic extension dragging trolley.
The utility model is realized in this way:
A kind of Pneumatic extension dragging trolley, including trolley body and cylinder mechanism, the cylinder mechanism include cylinder block and
The cylinder piston slided in cylinder block, the cylinder piston is connect with the trolley body drives carriage walking；The trolley sheet
Body includes the wheel of sweep and bottom, and the sweep center is equipped with can be forward along the through slot in carriage walking direction and in through slot
The swing fixture block of swing, the swing fixture block bottom front are connect by elastic parts with the sweep, and fixture block stress is being swung
It drives elastic parts to stretch when turning forward, then makes to swing fixture block recovery vertical position by the contraction of elastic parts.
Further:
The swing fixture block includes being arranged in the through slot rear end and the therewith fixture block of clearance fit, and be located at the card
The block bottom left and right sides and a pair of bearings for being fixed on the sweep, two bearings centres pass through connection axis connection, the connection
Axis is fixed on the fixture block bottom, and is fixedly connected with the elastic parts.
The elastic parts includes compressed spring.
The trolley body is fixedly connected with the cylinder piston by nut.
The trolley body passes through flexible scalable balance guide rod and the cylinder block two with cylinder piston cooperation
Side connection.
The shape of the fixture block includes right angled triangle, rectangle.
The fixture block rear end is additionally provided with vertical stop block at the top of the sweep.Fixture block can be made preferably to restore vertically to make
Industry.
The utility model has the advantages that the Pneumatic extension dragging trolley of the utility model in use, can disappear
Except pneumatic cylinder actuation is not sufficiently stable, have often cylinder chain extension bar deformation can not actuation the phenomenon that；Pneumatic extension dragging trolley
It is withstood forces greatly when operation, does not have desoldering and fall phenomenon, maintenance working hour is short, maintains easily, improving productivity.
Detailed description of the invention
The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structure top view of the utility model.
Fig. 2 is the side view of trolley body.
Fig. 3 is the force diagram for swinging fixture block and expecting rack trolley.
Specific embodiment
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of Pneumatic extension dragging trolley, including trolley body 1 and cylinder mechanism 2, the cylinder
Mechanism 2 includes the cylinder piston 22 slided in cylinder block 21 and cylinder block 21, and the cylinder piston 22 connects with the trolley body 1
Tape splicing moves trolley 1 and walks；The trolley body 1 includes the wheel 12 of sweep 11 and bottom, and the sweep 11 is equipped with along trolley
The through slot 13 of direction of travel and the swing fixture block that can be swung forward in through slot 13, the swing fixture block bottom front pass through compression
Spring 15 is connect with the sweep 11, is driven compressed spring 15 to stretch when swinging fixture block stress and turning forward, is then passed through pressure
The contraction of contracting spring 15 makes to swing fixture block recovery vertical position.The swing fixture block include be arranged in 13 rear end of through slot and with
Clearance fit fixture block 14, and at left and right sides of 14 bottom of fixture block and be fixed on a pair of bearings of the sweep 11
16, connected by connecting shaft 17 among two bearings 16, the connecting shaft 17 is fixed on 14 bottom of fixture block, and with the pressure
Contracting spring 15 is fixedly connected.
When the 14 rear stress of fixture block, the bearing 16 drives fixture block 14 to turn forward, until fixture block 14 does not stress,
And it is set to restore vertical position by the effect of spring 15.
Wherein the trolley body 1 is fixedly connected with the cylinder piston 22 by nut.
The trolley body 1 passes through the scalable balance guide rod 3 and the cylinder parallel with 22 two sides of cylinder piston
The connection of 21 two sides of body.
The fixture block 14 is triangular structure of right angle.
Concrete operations are as follows:
Existing air-leg front-end hook is removed, 12 creative activity trolley 1 of iron plate 11 and wheel, trolley 1 are reused
Upper installation nut connect use with cylinder piston 22, swings fixture block using iron block 14 and the production of bearing 16 on trolley 1, reuses
The control of spring 15 swings fixture block activity, is walked in 11 two sides of sweep using bolt installation balance guide rod control trolley 1 and cylinder 2
Track installs balance guide rod casing in cylinder block left and right sides, makes scalable balance guide rod 3, cooperation cylinder piston 22 is flexible, really
Trolley 1 is protected to walk on the same line with cylinder piston 22.
As shown in figure 3, when expecting that the stop block under pallet underbody seat touches fixture block 14, due to gravity, fixture block 14
It is pressed downward by stop block, bearing 16 drives fixture block 14 to turn forward, and when stop block passes through dilatory fixture block, fixture block 14 is in bullet
The effect of spring 15 is lower to restore vertical work pattern.When dragging trolley operation, fixture block 14 can touch stop block, to form resistance
Gear effect, at this time under the action of cylinder mechanism 2, material rack trolley smoothly advances with trolley 1.
Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model
Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model
Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should
Cover in the scope of the claimed protection of the utility model.
