Description

Technical Field

[0001] This utility model belongs to the technical field of steel structure processing equipment, and specifically relates to a swing clamping mechanism for conveying H-beams. Background Technology

[0002] H-beams, as structural profiles with optimized cross-sectional shape and excellent mechanical properties, are widely used in the foundations of building steel structures, industrial plants, bridges, and various heavy equipment. During their manufacturing process, processes such as welding assembly, drilling, cutting, and end milling all require precise conveying, positioning, and reliable clamping of the H-beams.

[0003] Traditional processes typically employ separate equipment: conveying is accomplished using roller conveyors, followed by clamping and positioning using independent hydraulic or pneumatic clamps. This method suffers from drawbacks such as the large space occupied by the conveyor rollers and positioning and clamping mechanisms, low positioning accuracy, and unstable clamping. For compact processing equipment, whether the design of the H-beam conveying, positioning, and clamping mechanisms can meet the support rigidity requirements of H-beam parts of different specifications will directly affect the cutting accuracy and processing efficiency of the equipment.

[0004] Therefore, developing a composite mechanism that integrates efficient conveying, precise positioning, and adaptive clamping functions, and can quickly adapt to the processing of various specifications of H-beams, has become the key to improving the automation level and processing efficiency of the production line. Utility Model Content

[0005] The purpose of this invention is to provide a swing clamping mechanism for transporting H-beams, so as to solve the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A swing clamping mechanism for conveying H-beams, comprising:

[0008] First pillar;

[0009] The first conveying roller and swing clamping mechanism include a support plate and a support base fixedly connected to the left end facade of the first column, a connecting seat and a side jaw installed on the left end of the support base, a cylinder support fixedly connected to the lower left end facade of the first column, a clamping cylinder swingingly connected to the cylinder support, two sets of inner swing rods symmetrically swingingly connected to the piston rod of the clamping cylinder, two sets of outer swing rods symmetrically connected to both sides of the support base, a pressing rod fixedly installed on the swing linkage mechanism formed by the two sets of inner and outer swing rods, and a first conveying roller unit spaced between the support base and the connecting seat, and a double sprocket and a chain drivenly connected to the input end of the first conveying roller unit, with the double sprockets connected to each other by a chain;

[0010] The first power transmission unit includes a first motor bracket fixedly connected to the lower left side of the first column, a first geared motor mounted on the first motor bracket, and a first motor sprocket connected to the output end of the first geared motor. The first motor sprocket and the double sprocket are connected by a chain.

[0011] The second column is symmetrically arranged on both sides of the H-beam steel part with the first column. The right end of the second column is provided with the same structure as the second conveying roller, the swing clamping mechanism and the second conveying power unit.

[0012] Furthermore, one end of the clamping cylinder is connected to the cylinder support via a first pin and can swing and rotate around the first pin; the two sets of inner swing rods are symmetrically arranged with the piston rod of the clamping cylinder and are connected via a second pin, and the two sets of inner swing rods can swing and rotate around the second pin.

The pressure rod is fixedly installed on the swing linkage mechanism composed of two sets of inner swing rods and two sets of outer swing rods. The vertical linear motion of the piston rod of the clamping cylinder can be converted into the left and right swinging clamping action of the pressure rod, thereby realizing the loosening and clamping of the outer side of the flange of the H-beam steel part.

[0014] Furthermore, a first conveying roller unit is connected between the support base and the connecting base through a bearing mounting hole. The first conveying roller unit includes multiple sets of conveying rollers. The conveying rollers are rotatably connected to the support base through a bearing assembly. The upper generatrices of the multiple sets of conveying rollers should be assembled to ensure coplanarity, and the H-beam part can be moved back and forth by contacting the bottom surface of the flange of the H-beam part.

[0015] Furthermore, the first and second columns can be fixedly installed on the base unit, which includes a bed, a first slide plate slidably connected to the bed in the front-back direction, a second slide plate slidably connected to the bed in the left-right direction, a first slide plate transmission mechanism for realizing the front-back movement of the first slide plate, and a second slide plate transmission mechanism for realizing the left-right movement of the second slide plate.

[0016] Furthermore, the first sliding plate is fixedly connected to the first column. The first sliding plate drives the first column to move back and forth, thereby enabling the positioning and clamping of the beveled H-beam steel parts.

[0017] Furthermore, the second sliding plate is fixedly connected to the second column. By moving the second column left and right through the second sliding plate, the positioning and clamping of H-beam steel parts of different specifications can be achieved.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model, through the symmetrical arrangement of the first and second columns, and by utilizing the first conveying roller and swing clamping mechanism and the second conveying roller and swing clamping mechanism symmetrically installed between the two columns, can realize the conveying, positioning and clamping of H-beam steel parts, thereby improving the positioning accuracy and processing efficiency of the equipment.
