Background technique
In the manufacturing process of city railway vehicle steel structure of car body, the corrugated plating of big component chassis skeleton, which mats formation to weld, to be used
Melt pole electrical arc spot welding is usually that people steps down in corrugated plating and main beam on corrugated plating by the weight of people itself in welding process
It compresses, is welded.In this case, because of the error of materials and parts, causing portion to rely solely on the gravity of people can not be by wave
Card and crossbeam pressure are tight.And welding is carried out in the case where materials and parts are not tight and will affect the quality of welding and the structural strength of component.
Utility model content
When the purpose of this utility model is for existing electric arc spot welding, corrugated floor is asked with what main beam contact surface did not pressed tightly
Topic, provide it is a kind of materials and parts can be pressed it is tight, to facilitate welding and guarantee the corrugated floor electric arc spot welding pressing device of welding quality.
To achieve the above object, the utility model provides a kind of chassis corrugated plating electric arc spot welding pressing device, and feature exists
In: including longitudinal movement part, pressing section and transverse shifting part, the longitudinal movement part includes crossbeam frame and upper
Lower sheave, respectively there are two hook arms, crossbeam frame both ends to distinguish each two pairs of setting below for installation respectively at crossbeam frame both ends
Vertical plate, top sheave are mounted between two pairs of vertical plates, and lower sheave is mounted between two hook arms；The pressing section includes liquid
Case, hydraulic cylinder, hydraulic push rod, profile-followed pressing plate, adjustable pressing block, support frame are pressed, hydraulic fluid tank is mounted on support frame upper plate, hydraulic cylinder
Lower end is fixedly mounted in support frame lower plate, and hydraulic push rod lower end is connected at the center of profile-followed pressing plate, is connected below profile-followed pressing plate
Adjustable pressing block is connect, a guide rod is respectively connect with profile-followed pressing plate both sides across support frame lower plate, is located at support frame lower plate or more on guide rod
Part is cased with spring；The transverse shifting part is that board ends respectively install a sliding block under support frame, below crossbeam frame
The sliding rail of installation one and sliding block cooperation.
The adjustable pressing block installation site corresponds to the groove of corrugated plating.
The fit form of the sliding block and sliding rail is the cooperation of dovetail groove type.
The lower sheave and car body side bar underclearance of the longitudinal movement part cooperate, and hold-down mechanism is prevented to be downwardly applied to
Crossbeam frame is jacked up by corrugated plating when pressure.
The utility model with chassis group become supporting track, make pressing device, pressing device can be formed along chassis into
Row longitudinal direction priming reaches any required position for carrying out electric arc spot welding on chassis.Board ends respectively install a sliding block under support frame,
The sliding rail of one with sliding block cooperation is installed below in crossbeam frame, need pressing section can along crossbeam frame transverse shifting
The position compressed extends downwardly briquetting, contacts with compacted position, and when compression, the hook arm in crossbeam frame is hooked in chassis group
At lower aerofoil on the reaction force of compression is provided, crossbeam frame is by corrugated plating top when hold-down mechanism being prevented to be downwardly applied to pressure
It rises.It is easy to operate, time saving, laborsaving using hydraulic compression mode.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model；
Fig. 2 is the front view of the utility model；
Fig. 3 is the side view of the utility model；
Fig. 4 is the partial enlarged view of Fig. 3.
Specific embodiment
- Fig. 4 referring to Fig.1, specific embodiment of the present invention include longitudinal movement part, pressing section and laterally move
Dynamic part, the longitudinal movement part includes crossbeam frame 1, top sheave 2, lower sheave 3,1 both ends connecting lateral plate of crossbeam frame
4, connecting bottom board 5 below both ends, respectively there are two hook arms 6, hook arm 6 to be made of two parts for installation respectively in two end side panels 4,
Length can be adjusted according to different automobile types.Front and back is each on bottom plate 5 below crossbeam frame both ends connects a pair of of vertical plate 7, and top sheave 2 is pacified
On top sheave axis 8 between two pairs of vertical plates 7, lower sheave 3 is mounted on the downslide on the connecting plate 9 between two hook arms 6
On wheel shaft 10, lower sheave 3 and chassis form the cooperation of 11 underclearances, crossbeam frame quilt when hold-down mechanism being prevented to be downwardly applied to pressure
Corrugated plating 12 jacks up.
The pressing section include hydraulic fluid tank 13, hydraulic cylinder 14, hydraulic push rod 15, profile-followed pressing plate 16, adjustable pressing block 17,
Support frame, hydraulic fluid tank are mounted on support frame upper plate 18, and hydraulic cylinder lower end is fixedly mounted in support frame lower plate 19, hydraulic push rod
Lower end is connected at the center of profile-followed pressing plate, and profile-followed pressing plate 16 connects adjustable pressing block 17 below, across support frame lower plate and with the shape
Pressing plate both sides respectively connect a guide rod 20, are located at support frame lower plate above section on guide rod and are cased with spring 21, the adjustable pressing block
Installation site corresponds to the groove of corrugated plating.
The transverse shifting part is that board ends respectively install a sliding block 22 under support frame, is installed below in crossbeam frame
One sliding rail 23 cooperated with sliding block.The fit form of the sliding block and sliding rail is the cooperation of dovetail groove type.
The course of work: when pushing entire pressing device, pressing device can be on corrugated plating generally longitudinally by top sheave 2
Mobile, lower sheave is not contacted with chassis composition lower part.When needing transverse shifting, support frame lower plate 19, entire pressing section are pushed
By sliding block along sliding rail transverse shifting, it is moved to required welding portion, the hydraulic push rod 15 for operating hydraulic cylinder moves downward, and drives
Corrugated plating is compressed downwards with the adjustable pressing block on type pressing plate 16, and when device compresses corrugated plating downwards, hook arm catches on chassis group
At compression purpose of the completion to chassis corrugated plating；When the hydraulic push rod of hydraulic cylinder moves upwards, drives and leave wave with type pressing plate
Card, spring 21 are sprung back, and increase stability when leaving corrugated plating with type pressing plate 4, to realize to corrugated plating different parts
Compress operation.
When not having pressure, pressing device manually pushes portraitlandscape that can move by operator, frictional force
Very little, it is manually very laborsaving when the two directions push, without the mobile pressing device of external force.
