Abstract
The invention relates to a bodywork locking device for positioning and locking the bodywork in the process of automatic laser welding the bodywork. It comprises a lifting device and positioning devices. Wherein, the lifting device is mounted at the tail of locking device; said positioning devices are mounted at two sides of feeding line, which comprise four groups at front, back, left and right. The lifting cam and connecting bar are mounted on rotational axle, via base bearing, to be fixed on two sides of fixing bracket of lifting device; the lifting cylinder is fixed on the fixing bracket; one end of piston rod of cylinder is connected to the connecting bar; the positioning cylinder is fixed on the fixing bracket of positioning device; another end of piston rod is connected to the positioning block. The invention has the advantages that: when the bodywork is fed to preset working position, the lifting device uplifts one end of it, and the pry body can contact the feeding line with four points, to avoid the worse contact between them caused by distortion; then the operating four positioning cylinders at two sides of bodywork, to support two beams of bodywork, therefore, the bodywork is fixed.
Description
Technical field
What the present invention relates to is the vehicle body-locking mechanism that vehicle body is positioned locking when body of a motor car laser welds automatically, belongs to the mechanical automation technical field.
Background technology
Body of a motor car generally all is that sled band vehicle body directly moves on conveyer on main bonding wire the time, and sled and vehicle body do not fix.When each station stops all be retaining on sled, and welding robot requires vehicle body to stablize when welding.So on body of a motor car sealing wire in the past, directly do not weld.After pipeline was delivered to car body the appointment station, transmission line body is whole to descend, and vehicle body is fallen on the weld jig, and welding robot welds again then, and after welding finished, pipeline was sent vehicle body into next station again vehicle body jack-up.This welding scheme not only pipeline is comparatively complicated, also requires each station that special-purpose weld jig is arranged, and production cost is higher,
Summary of the invention
The objective of the invention is to defective at above-mentioned existence, a kind of vehicle body-locking mechanism that vehicle body is positioned locking is proposed, lifting body in the vehicle body-locking mechanism independently is installed on the afterbody of vehicle body-locking mechanism, positioner in the vehicle body-locking mechanism is installed on the transmission line body both sides, is total to the quadruplet positioner all around.After sledge body band vehicle body was transported to the appointment station, lifting body made sledge body and pipeline become contact at 4 sledge body vehicle body one end jack-up, had avoided contacting with the bad of transmission line body because of the sledge body uses the distortion back for a long time; Four of the car body both sides positioning cylinder actions directly withstand on two crossbeams of vehicle body then, play the fixedly effect of vehicle body.Thereby effectively overcome existing in prior technology pipeline complexity, also required each station that special-purpose weld jig, defectives such as production cost height are arranged.
Technical solution of the present invention: it is characterized in that being made up of lifting body, positioner, wherein lifting body independently is installed on the afterbody of vehicle body-locking mechanism; Positioner is installed on the transmission line body both sides, is total to quadruplet all around; Jacking cam, connecting rod are loaded on the rotating shaft, and the jacking cylinder is fixed on the fixed mount, and one of cylinder piston rod is connected with connecting rod; Positioning cylinder is fixed on the positioner fixed mount, and the cylinder piston rod other end is connected with locating piece.
Advantage of the present invention: because the lifting body in the vehicle body-locking mechanism is the afterbody that independently is installed on vehicle body-locking mechanism, and the quadruplet positioner in the vehicle body-locking mechanism is installed on the transmission line body both sides, divides position all around.After sledge body band vehicle body was transported to the appointment station, lifting body made sledge body and pipeline become contact at 4 sledge body vehicle body one end jack-up, had avoided contacting with the bad of transmission line body because of the sledge body uses the distortion back for a long time; Four of the car body both sides positioning cylinder actions directly withstand on two crossbeams of vehicle body then, play the fixedly effect of vehicle body.The tool transmission line body is simple in structure in addition in the present invention, need not carry out vertical lift; Equipment cost is low; Characteristics such as maintenance is convenient.

Fig. 3 is the left view of lifting body
Fig. 4 is the front view of positioner
1 is lifting body among the figure, the 2nd, and positioner, the 3rd, jacking cam, the 4th, connecting rod, the 5th, jacking cylinder, the 6th, lifting body fixed mount, the 7th, rolling bearing units, the 8th, rotating shaft, the 9th, locating piece, the 10th, positioning cylinder, the 11st, positioner fixed mount.
The specific embodiment
The contrast accompanying drawing, its structure is made up of lifting body 1, positioner 2, and wherein lifting body 1 independently is installed on the afterbody of vehicle body-locking mechanism, and positioner 2 is installed on the transmission line body both sides, is total to quadruplet all around.
Jacking cam 3 in the lifting body 1, connecting rod 4 are loaded on the rotating shaft 8, rely on rolling bearing units 7 to be fixed in lifting body fixed mount 6 both sides, and jacking cylinder 5 is fixed on the lifting body fixed mount 6, and one of cylinder piston rod is connected with connecting rod 4.
Positioning cylinder 10 in the positioner 2 is fixed on the positioner fixed mount 11, and the cylinder piston rod other end is connected with locating piece 9.
During work, jacking cylinder 5 actions after sledge body band vehicle body enters the appointment station, drivening rod 4, rotating shaft 8, jacking cam 3 are around rolling bearing units 7 rotations, with a side jack-up of sledge body band vehicle body; Vehicle body is locked in four positioning cylinder 10 actions simultaneously.
Claims (4)
