Description
Technical Field
The utility model belongs to the technical field of the automobile parts production welding, concretely relates to floating platform of self-balancing function is taken in welding.
Background
Generally, when spot welding fixtures are used in fixed spot welding machines for production, the spot welding fixtures need to be fixedly mounted on a platform. In order to compensate the loss of the electrode after spot welding or grinding at every time, the platform can float along the length direction of the electrode, the upper electrode and the lower electrode are attached to a product during spot welding, and when the existing floating platform is under the action of an eccentric force, the horizontal balance of the up-and-down floating of the platform completely depends on the precision of the guide pillar and the guide sleeve. The guide pillar and guide sleeve is easy to block when the gap is small, and the platform cannot be horizontally lifted when the gap is large, so that the phenomenon that the platform inclines to the side of the eccentric force occurs, and the welding quality is poor.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem to provide a floating platform of self-balancing function is taken in welding to the current situation of prior art, can improve floating platform stability and promote the welding quality.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the floating platform with the self-balancing function is characterized by comprising a frame and a floating bottom plate, wherein four groups of guide elements are arranged between the frame and the floating bottom plate, an air cylinder and a movable joint are arranged on the side part of the floating bottom plate, the air cylinder is connected with the frame and the floating bottom plate through the movable joint, each group of guide elements is provided with a spring, and a balancing element is arranged at the lower end of the floating bottom plate.
In the floating platform with the self-balancing function for welding, the guide element comprises guide pillars and guide sleeves, and a spring is arranged between each group of guide pillars and guide sleeves to offset the downward tensile force of the cylinder.
In the floating platform with the self-balancing function for the welding strip, the balancing element comprises bearing seats, a connecting shaft, a gear and a rack, the bearing seats are respectively arranged on the left and the right of a mounting plane of the frame, the connecting shaft is mounted between the two bearing seats, the gear is respectively mounted at the two ends of the connecting shaft, and the rack is mounted on the floating bottom plate through an adjusting block and meshed with the gear.
Compared with the prior art, the utility model has the advantages of mainly through guide pillar, guide pin bushing and spring, realize that the mechanism floats from top to bottom, through rack and pinion and connecting axle, realize that the mechanism keeps horizontal balance to effectively block dead phenomenon in welding process, improve floating platform stability and promote the welding quality.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
In the figure, 1 a floating bottom plate, 2 a frame, 3 a guide sleeve, 4 springs, 5 guide pillars, 6 air cylinders, 7 movable joints, 8 connecting shafts, 9 racks, 10 adjusting blocks, 11 gears and 12 bearing seats; 13 a guide element; 14 balancing elements.
As shown in fig. 1, 2 and 3, the floating platform with the self-balancing function for welding comprises a frame 2 and a floating bottom plate 1, wherein four groups of guide elements 13 are arranged between the frame 2 and the floating bottom plate 1, an air cylinder 6 and a movable joint 7 are arranged on the side of the floating bottom plate 1, the air cylinder 6 is connected with the frame 2 and the floating bottom plate 1 through the movable joint 7, a spring 4 is arranged on each group of guide elements 13, and a balancing element 14 is arranged at the lower end of the floating bottom plate 1, wherein the floating platform mainly utilizes the guide elements 13 to realize up-and-down floating, and utilizes the balancing element 14 to realize that a mechanism keeps horizontal balance.
Specifically, the guide element 13 comprises guide columns 5 and guide sleeves 3, the frame 2 and the floating bottom plate 1 use four groups of guide columns 5 and guide sleeves 3 as the guide element 13 to realize vertical up-and-down lifting action, the cylinder 6 is connected with the frame 2 and the floating bottom plate 1 through the movable joint 7 to provide power for the up-and-down movement of the floating bottom plate 1, the movable joint 7 is connected with a piston rod capable of effectively protecting the cylinder 6, and a spring 4 is arranged between each group of guide columns 5 and guide sleeves 3 to offset the downward pulling force of the cylinder 6; the balance element 14 comprises bearing seats 12, a connecting shaft 8, a gear 11 and a rack 9, the bearing seats 12 are respectively arranged on the left and the right of the installation plane on the frame 2, the connecting shaft 8 is arranged between the two bearing seats 12, and the gear 11 is respectively arranged at two ends of the connecting shaft 8; the rack 9 is arranged on the floating bottom plate 1 through an adjusting block 10 and is meshed with a gear 11, and the backlash is adjusted through the adjusting block 10.
The cylinder 6 is ejected to the upper limit position, and the floating bottom plate 1 is lifted to the upper limit position; the cylinder 6 retracts to the lower limit position, and the floating bottom plate 1 is lowered to the lower limit position; in the process of the up-and-down lifting movement of the floating bottom plate 1, the guide post 5, the movable joint 7, the rack 9 and the adjusting block 10 move together; because two pairs of gears 11 and the rack 9 are meshed, the four guide pillars 5 are ensured to move up and down synchronously all the time, and the floating bottom plate 1 can keep horizontal balance up and down movement no matter whether being subjected to eccentric force, thereby ensuring the integral quality of welding.
The embodiments described herein are merely exemplary and various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope and spirit of the invention as defined by the claims.
