Background

The heat exchange tube of heat exchanger need be with the help of the welding bench when the welding, and the correlation technique is like the utility model patent of application number 202021680330.7 the manual welding bench of air conditioner heat exchanger, when using, need set up the work piece slope through the welding bench to when making the welding, the solder can carry out local downflow, guarantees welded quality.

In the actual production process, when welding the heat exchange tube of large-scale heat exchanger, as shown in fig. 1, generally utilize jacking cylinder 2 to promote to rotate platen 3 that sets up on base 1 and rotate, nevertheless promote platen 3 through jacking cylinder 2 alone and rotate, have great requirement to the length of jacking cylinder 2, and after length grow, the arm of force that platen 3 acted on jacking cylinder 2 also can increase to lead to the intensity of jacking cylinder 2 also can reduce.

Accordingly, the inventors have made extensive studies to obtain this.

SUMMERY OF THE UTILITY MODEL

The utility model provides a two stroke climbing mechanisms of welding bench for it is big to solve among the prior art welding bench jacking cylinder length, problem that intensity is low.

The utility model provides a following technical scheme: the utility model provides a two stroke climbing mechanism of welding bench, includes the base, the base rotates installs the platen, and pedestal mounting is used for driving platen pivoted jacking cylinder, it promotes the piece to slide on the base to be equipped with, the other end that jacking cylinder and platen are connected with promote the piece and rotate to be connected, be fixed with on the base and promote the cylinder, promote the cylinder the head with promote a fixed connection.

Preferably, the surface of base is equipped with the spout, promote piece and spout sliding connection.

Preferably, the bottom is provided with an opening in a penetrating manner, and the length direction of the opening is consistent with that of the sliding chute.

Preferably, pulleys are installed on two sides of the bottom of the pushing block, and the pulleys are in rolling connection with the bottoms of the sliding grooves.

Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses control the platen of welding bench among the prior art through the flexible of double cylinder, when the welding heat exchange tube and need incline the platen, arrange the platen surface in with the work piece, control the extension of jacking cylinder earlier, the extension of control push cylinder again to the lower extreme that drives the jacking cylinder slides right, makes the jacking cylinder can be with shorter length jack-up platen that makes progress.

Drawings

FIG. 1 is a schematic diagram of a prior art structure;

FIG. 2 is a schematic view of the present invention;

fig. 3 is the schematic view of the installation structure of the pushing block of the present invention.

In the figure: the device comprises a base 1, a jacking cylinder 2, a platen 3, a pushing cylinder 4, a sliding chute 5, a pushing block 6, a spring 7, a sliding block 8, a pulley 9 and an opening 10.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the lifting device comprises a base 1, a platen 3 used for placing a workpiece is rotatably arranged on the base 1, a sliding groove 5 is formed in the surface of the base 1, a pushing block 6 is arranged in the sliding groove 5 in a sliding mode, a jacking cylinder 2 is connected between the pushing block 6 and the platen 3, two ends of the jacking cylinder 2 are respectively connected with the pushing block 6 and the platen 3 in a rotating mode, the platen 3 is driven to rotate when the jacking cylinder 2 stretches out and draws back, a pushing cylinder 4 is arranged in the sliding groove 5, two ends of the pushing cylinder 4 are respectively fixedly connected with one end of the sliding groove 5 and the pushing block 6, and the pushing block 6 is pushed to slide in the sliding groove 5;

at the during operation, place the work piece on platen 3, upwards jack-up platen 3 through the extension of jacking cylinder 2, in the extension of jacking cylinder 2, promote the promotion piece 6 right through the extension of promotion cylinder 4, the lower extreme that promotes jacking cylinder 2 through promoting the piece 6 slides to the right end, thereby make jacking cylinder 2 can be with the ascending jack-up platen 3 of shorter length, the length of jacking cylinder 2 diminishes like this, platen 3 and the heavy object on its surface act on the arm of force length also corresponding shortening of jacking cylinder 2.

In order to make and promote the gliding more smooth and easy in spout 5 of piece 6, it is further, the bottom that promotes 6 both sides is equipped with two recesses, it is equipped with slider 8 to slide in the recess, the upper end fixed connection spring 7 of slider 8 and recess, and pulley 9 is installed to the lower extreme of slider 8, the bottom roll connection of pulley 9 and spout 5, through the setting of pulley 9, the sliding friction who promotes 6 and spout 5 bottoms changes the rolling friction of pulley 9 and spout 5 bottoms, when promoting cylinder 4 and promoting 6, effectively reduce the frictional force who promotes 6 and spout 5 bottoms, through the setting of spring 7, when there is small debris in the bottom of spout 5, spring 7 shrink cushions, make pulley 9 pass through small barrier smoothly.

Furthermore, the width of the pushing block 6 is consistent with that of the sliding groove 5, an opening 10 is formed in the bottom of the sliding groove 5 in a penetrating mode, when sundries or solder fall into the sliding groove 5, the sundries such as the solder can be conveniently swept into the opening 10, and the pushing block 6 is prevented from being blocked in sliding.
