A conveying plate is converted to move time and again along a circular arc track in a certain direction to realize the aim of gradually transferring a former working procedure to a next working procedure. The utility model has the advantages of advancement, reasonableness, convenience, time saving, labor saving, stable transfer, regular workpiece arrangement, small ground occupying and convenient field management, etc., and is especially suitable for transferring medium and small-sized workpieces to the pipeline operation of mechanical processing.

Description

The automatic transfer device of workpiece

The utility model relates to the conveyer of the carrier with different processes and drawback movement, is the automatic transfer device of a kind of special transmission workpiece between the manufacturing procedure of front and back.

In mechanical industry, process complicated workpiece, generally all need through several roads manufacturing procedure.The workpiece of processing, generally all adopts working position apparatus car, working position apparatus frame, working position apparatus frame to wait to transmit to the transmission another procedure from one procedure.As process the cylinder block workpiece of motor cycle engine, generally transmit with the working position apparatus car.Whenever fill 100 processing works, the working position apparatus car just pushes next process and processes.If the cylinder block workpiece of processing motor cycle engine has 10 procedures, so, workpiece must remain on more than 1000 just can accomplish continuous production.The surface of workpiece workpiece when putting transmission is easy to clashing and breaking simultaneously, production site also very broad, it is chaotic that processing site seems easily, the working position apparatus car is carried out also effort, therefore when producing in enormous quantities the workpiece of each operation processing with the working position apparatus car wait transmit exist time-consuming, effort, floor area is big, field management is than defectives such as confusions.

The purpose of this utility model is that the conveying of a kind of practicality of design brings the transmission workpiece, and it has efficiently, is suitable for, and transmits steadily, saves time, and is laborsaving, and small investment, the efficient height, and advantage such as save space can overcome the shortcoming of existing working position apparatus transmission workpiece.

This programme is power with the electrical motor, adopts power drive, shelf and the supporting structure of existing load-transfer device.It drives circular movement that piston crank mechanism carries out with electrical motor and converts delivery board in a certain direction arc track motion once and again to after slowing down, be passed to the purpose of next procedure step by step by last process to realize processing work.

Accompanying drawing is a structural representation of the present utility model, among the figure:

1--shelf: 2--delivery board; The 3--piston crank mechanism; The 4--supporting base;

The 5--motor; The 6--chain; The 7--workpiece; The 8--drop-gear box; The 9--safety device

In conjunction with the accompanying drawings, the utility model is further described.

Shelf 1 is a skeleton structure, and last plane is made up of two parallel shaped steel, makes the length and the width of different size according to the distance between the operation.Adopt square tube, pipe or angle bar, shaped steel such as band iron are made.When processing medium and small workpiece, the length of shelf is the best to be no more than 3 meters.The width of shelf is the best than the big 5～20mm of workpiece of processing with big 10mm, but grade width of opening in the middle of it should be less than the width of workpiece.Delivery board 2 is to make with general plate, and the hardness of plate is unsuitable really up to the mark, generally uses plank, bakelite board, and carboard etc. are made, and use bakelite board the best.The width of delivery board is the best than the little 10～30mm of workpiece of processing with little 20mm, and the width of opening grade less than shelf, and an end of the following and connecting rod of delivery board is connected, and the other end of connecting rod links to each other with crank.The quantity of piston crank mechanism is selected according to the length of delivery board, can be with one, two, three, four.And should guarantee that each piston crank mechanism rotates synchronously.Be best generally with two piston crank mechanisms.Piston crank mechanism is fixed on the supporting base with the shelf connecting rod mechanism.The surface of supporting base is provided with inhibiting device, can be used to the position of adjust crank connecting rod mechanism on supporting base.Supporting base and shelf connecting portion have kidney shape groove, can be used to regulate the upper and lower position of supporting base at shelf, to guarantee that delivery board is higher than the frame plane when rise is advanced, are lower than the frame plane when decline is returned.Motor 5 is selected the motor of suitable power for use according to the workpiece weight of processing, and 2 or several piston crank mechanism must be synchronized with the movement, so adopt chain gear.Chain 6 can be selected the chain of Regular Bicycle for use.Drop-gear box 8 is installed between motor and the piston crank mechanism, selects reduction ratio for use 40: 1 or decides according to demand.The end that safety device 9 is contained in shelf adopts general limit switch.

Behind electric motor starting, drive piston crank mechanism and rotate by drop-gear box, chain, delivery board is also along with connecting rod is made circular movement.Connecting rod forwards preceding stop to, and delivery board is in the forward position of shelf and is lower than the shelf horizontal surface.When connecting rod forwarded vertex to, delivery board was also along with rising, and the workpiece that will place when exceeding the shelf horizontal surface on the top of the shelf holds up, and connecting rod is rotated further.During to the back stop, delivery board also and then reduces backward gradually, is reduced to when being lower than the shelf horizontal surface, and the workpiece that the delivery board pop-up also will be shelved on the top of the shelf.This is a course of conveying, and workpiece has been carried a step backward.Motor constantly rotates, and piston crank mechanism is also made circular movement repeatedly, and delivery board also just ceaselessly rises from shelf is anterior, falls to the shelf rear portion, and workpiece is transmitted step by step backward.Exceed the shelf horizontal surface from delivery board and be the distance that workpiece moves after on the top of the shelf to moving the chord length distance be lower than the circular movement that the shelf horizontal surface carried out backward.The adjustable-speed joint that workpiece moves is on the top of the shelf backward installed the supporting base of piston crank mechanism and delivery board, the height of stop is the same with the shelf level when high before supporting base is adjusted upward to delivery board, the distance that workpiece moves on the top of the shelf backward is the diameter of delivery board circular movement, so the speed that workpiece transmits backward is for the fastest.The vertex of adjusting to delivery board when motion downwards when supporting base is during a little more than the shelf horizontal surface, the speed that workpiece transmits is the slowest, and the vertex when conveyer moves is adjusted to when being lower than the shelf horizontal surface, bumps less than workpiece during the delivery board motion, workpiece can only stop on the top of the shelf, can not transmit backward.At the rear portion of shelf a safety device has been installed also.When delivery board is delivered to the place that safety device is housed on the shelf, worker to workpiece
