Fig. 7 is the work flow diagram of the workpiece shipping method in the embodiment of the present invention.
Below in conjunction with 7 pairs of workpiece consigned using the workpiece conveying device 100 in the present embodiment to workpiece 200 of attached drawing
Shipping method is made an explanation, the specific steps are as follows:
Step S1 carries out initialization adjusting to support arm 20 and floatation element 30, so that two support arms 20 are relative to holding
The center line of trailing arm mounting plate 102b is symmetrical, and two floatation elements 30 are moved to the interposition of the stroke range of floatation element 30
Set place；
Workpiece conveying device 100 is moved near workpiece 200 by step S2, according to the height of workpiece 200 to lifting group
Part 102 carries out lifting moving, to be adjusted to the position of support arm 20 in the vertical direction；
Step S3 continues to move to workpiece conveying device 100 until support arm 20 is located at the underface of workpiece 200；
Step S4, according to the width of workpiece 200 to the spacing between support arm 20 and support arm mounting plate 102b's
Position on length direction is adjusted；
Step S5 adjusts position of the floatation element 30 on 20 length direction of support arm according to the length of workpiece 200
It is whole；
Step S6 allows lifting assembly 102 to continue to rise movement, until support arm 20 holds up workpiece 200, was rising
Cheng Zhong, while the position of floatation element 30 is finely adjusted, so that positioning pin 307 is accurately inserted into dowel hole；
Step S7, travelling workpiece conveying device and the position for adjusting support arm 20 and floatation element 30, so that at workpiece 200
At the surface of target position, lifting assembly 102 is allowed to carry out decline movement, until support arm 20 and workpiece 200 are detached from, under
During drop, while the position of floatation element 30 is finely adjusted, workpiece 200 is enabled accurately to be placed into target position
Place.
Wherein, in step S4 and step S5 according to the position of positioning pin 307 and dowel hole to support arm 20 and floating group
The position of part 30 is adjusted, and the location error of positioning pin 307 and dowel hole is not more than ± 5mm.
The method being finely adjusted in step S6 to the position of floatation element 30 includes following sub-step:
Mobile connecting rod 302a is moved to open position, so that float plate 306 is in quick condition by step S6-1；
Step S6-2 moves float plate 306, so that positioning pin 307 is inserted into dowel hole；
Mobile connecting rod 302a formula is moved to locked position, so that float plate 306 enters locking state by step S6-3.
During lifting assembly 102 continues to lift up, by whether there is interference to judge whether positioning pin 307 is inserted into
In dowel hole, interfere if it exists, illustrates that positioning pin 307 is already inserted into dowel hole, just lock floatation element, if not depositing
Then continue to be finely adjusted the position of floatation element 30 in interference until positioning pin 307 is inserted into dowel hole.
In step S7 during the transport of workpiece 200, the lower surface lowest part of workpiece 200 is not less than at a distance from ground
100mm。
After completing subjob delivery, floatation element is locked again and workpiece conveying device 100 is moved to specified work
Position or the delivery operation carried out next time prepare.
Embodiment action and effect
According to the workpiece conveying device of the present embodiment, due to for support workpiece and inciting somebody to action with mobile mechanism and support arm
Workpiece is moved to target position, therefore operating personnel is more convenient to the movement of workpiece laborsaving when carrying out operation, can be effective
Ground reduces operation intensity, it is only necessary to which a people can fulfil assignment, while workpiece will not generate shaking in operation process, also be not easy
It the accidents such as causes to fall, improves the safety of operation.Since with regulating mechanism, operating personnel is in operation without logical
The position of workpiece can be adjusted by crossing manpower, so that the positioning to workpiece is more accurate, more efficient, the operation of operation
When also more easily.
Due to being respectively used to telescopic support arm connecting rod, lateral adjustments component and vertical adjustment component
To position of the spacing, support arm between two support arms on the length direction of support arm mounting plate and floatation element along holding
Position on trailing arm length direction is adjusted, therefore there are three the adjusting function on direction for the regulating mechanism tool in the present embodiment
Can, further improve the precision and operating efficiency to location of workpiece positioning.
It, can be to the position of positioning pin when floatation element is in quick condition due to being additionally provided with floatation element on support arm
It sets and is further finely tuned, so that positioning pin more accurately can be inserted into dowel hole by operating personnel when operation
In, further improve homework precision.In addition, workpiece can be limited along horizontal when floatation element is in locking state
Displacement on direction improves the safety in operation process so that workpiece does not cause to shake.
Due to being respectively equipped with graduated scale on support arm mounting plate and support arm, operating personnel's energy in operation process
Enough positioning more accurate according to the instruction of scale, reduce the regulating time of support arm.
Due to being equipped with regulation handle on support arm connecting rod, lateral adjustments component and vertical adjustment component,
It is more convenient to the position adjustment of support arm and floatation element in operation process, it operates simpler.
Since support arm passes through support arm mounting plate by slot, the mounting height of support arm is significantly reduced, so that holding
The upper surface of floatation element on trailing arm is slightly above the upper surface of support arm mounting plate, so that workpiece can in operation process
It fully moves backward, until the lifting limit plate of support arm mounting plate is abutted against, so that the workpiece support in the present embodiment
Shipping unit center of gravity moves back, and increases the effective and safe load of the workpiece conveying device in the present embodiment, can be suitable for large scale
Heavy workpiece, security performance is stronger.
Frame structure is used by workpiece conveying device in this present embodiment, while reducing self weight and outer dimension
Bearing capacity is effectively promoted, therefore the space requirement of various complexity can be suitable for.
The preferred embodiment of the present invention has been described in detail above.It should be appreciated that the ordinary skill of this field is without wound
The property made labour, which according to the present invention can conceive, makes many modifications and variations.Therefore, all technician in the art
Pass through the available technology of logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Scheme, all should be within the scope of protection determined by the claims.
