Description

Technical Field

[0001] This utility model relates to the field of metal grid processing technology, and in particular to an assembly fixture for metal grids. Background Technology

[0002] Metal gratings possess advantages such as high strength, lightweight, corrosion resistance, wear resistance, simple and convenient installation, and ease of maintenance, making them widely used in civil and industrial applications. Metal gratings mainly consist of flat steel bars and crossbars. In existing technologies, the flat steel bars are typically arranged with pre-cut slots, and the crossbars are then hammered into the slots before welding. This manual method significantly limits the production efficiency of metal gratings in industrialized, large-scale production. Utility Model Content

[0003] The purpose of this invention is to provide an assembly fixture for metal grilles, which improves the assembly efficiency of metal grilles.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an assembly fixture for a metal grille, comprising a frame, a base, a lifting seat, and a lifting drive mechanism for driving the lifting seat to move up and down. The base is provided with an assembly station. The lifting seat is provided with multiple docking slots, a clamping plate located in the docking slot, a clamping drive mechanism for driving the clamping plate to move, a support plate located below the docking slot, and a connecting plate connecting the support plate and the clamping plate. The lifting seat is provided with a lower pressing seat located above the docking slot, and a lower pressing hydraulic cylinder for driving the lower pressing seat to move up and down. Multiple lower pressing blocks are fixed at the lower end of the lower pressing seat, and the multiple lower pressing blocks correspond one-to-one with the multiple docking slots.

[0005] By adopting the above technical solution, workers pre-place the grating frame with flat steel bars at the assembly station. The crossbars are placed in the mating slots and supported by a support plate below the slots. A clamping drive mechanism moves the clamping plate to clamp the crossbars against the inner wall of the mating slot. Simultaneously, a connecting plate connected to the clamping plate moves the support plate away from directly below the mating slot. The length of the mating slot matches the length of the crossbars. A lifting drive mechanism lowers the lifting seat, bringing the crossbars in the mating slots close to and aligned with the notch in the flat steel at the assembly station. At this point, a hydraulic cylinder lowers the pressure seat, and the pressure block enters the mating slot, pressing the crossbars into the notch in the flat steel, thus improving assembly efficiency.

[0006] It should be noted that the clamping plate's function is to initially clamp the crossbar; the clamping force is not set very high, only enough to initially fix the crossbar's position. During the subsequent pressing process of the lowering seat and lowering block, the lowering hydraulic cylinder applies a larger force, easily pressing down the clamped crossbar and moving it downwards to the flat steel.

[0007] A further feature of this invention is that the clamping drive mechanism includes a clamping hydraulic cylinder fixed to the lifting seat and a synchronization frame slidably connected to the lifting seat. The piston rod of the clamping hydraulic cylinder is fixed to the synchronization frame, and multiple clamping plates are all fixed to the synchronization frame.

[0008] By adopting the above technical solution, the clamping hydraulic cylinder drives the synchronous frame to move, and the synchronous frame drives all the clamping plates to move.

[0009] A further feature of this invention is that the synchronization frame is fixed with multiple sliders, the lifting seat has at least two grooves, and the multiple sliders are slidably connected in the grooves.

[0010] By adopting the above technical solution, the movement of the synchronization frame is made smooth.

[0011] A further feature of this invention is that the frame is fixed with four first guide columns, and the lifting seat is fixed with four first guide sleeves, the first guide sleeves being fitted onto the guide columns.

[0012] A further feature of this invention is that the lifting drive mechanism is a lifting drive hydraulic cylinder mounted and fixed on the frame, and the piston rod of the lifting drive hydraulic cylinder is fixed to the lifting seat.

[0013] A further feature of this invention is that the lifting seat is fixed with four second guide columns, and the lower pressing seat is fixed with four second guide sleeves, the second guide sleeves being fitted onto the second guide columns.

[0014] A further feature of this invention is that a top plate is fixed to the upper end of each of the four second guide columns, and the downward hydraulic cylinder is mounted and fixed on the top plate.

[0015] The beneficial effects of this utility model are as follows: By placing the grid frame with flat steel at the assembly station, the worker places the crossbar into the docking slot, the clamping drive mechanism drives the clamping plate to clamp the crossbar in the docking slot, and the downward hydraulic cylinder drives the downward pressing seat to descend. The downward pressing block in the downward pressing seat presses the crossbar into the notch of the flat steel, thus completing the entire assembly operation. By adopting a combination of manual feeding and machine assembly, the assembly efficiency and accuracy of metal grids are improved, and the product yield is increased. Attached Figure Description

Detailed Implementation

[0022] An assembly fixture for a metal grille, such as Figures 1 to 5 As shown, the system includes a frame 1, a base 2, a lifting seat 3, and a lifting drive mechanism 4 for raising and lowering the lifting seat 3. The base 2 has an assembly station 21 for placing the grille frame 9 with flat steel bars 91. The frame 1 is fixed with four first guide columns. The lifting seat 3 has four first guide holes 33, each containing a first guide sleeve fitted onto a first guide column. The lifting drive mechanism 4 is a lifting drive hydraulic cylinder mounted and fixed to the frame 1. The piston rod of the lifting drive hydraulic cylinder is fixed to the lifting seat 3. The piston rod of the lifting drive hydraulic cylinder can drive the lifting seat 3 to rise and fall.

[0023] Four second guide columns 6 are fixed on the lifting base 3. A top plate 61 is fixed to the upper end of the four second guide columns 6, and a downward hydraulic cylinder 8 is installed and fixed on the top plate 61. A downward pressing seat 7 is provided above the lifting base 3. The downward pressing seat 7 has four second guide holes, and a second guide sleeve is fixed in each guide hole. The second guide sleeve is fitted onto the second guide columns 6. The piston rod of the downward hydraulic cylinder 8 is fixed to the downward pressing seat 7 and is used to drive the downward pressing seat 7 to rise and fall.

[0024] Multiple pressing blocks 71 are fixed to the lower end face of the pressing seat 7. The lifting seat 3 has multiple docking slots 31, each corresponding to a notch on the flat steel 91. The lifting seat 3 has multiple clamping plates 34 located within the docking slots 31. The lifting seat 3 has a clamping drive mechanism 5, which includes a clamping hydraulic cylinder 51 fixed to the lifting seat 3 and a synchronization frame 52 slidably connected to the lifting seat 3. The piston rod of the clamping hydraulic cylinder 51 is fixed to the synchronization frame 52, and the multiple clamping plates 34 are also fixed to the synchronization frame 52. Multiple sliders are fixed to the synchronization frame 52. The lifting seat 3 has at least two sliding grooves 32, and the multiple sliders are slidably connected within these grooves. Connecting plates 35 are fixed to both sides of the lower end of the clamping plates 34, and a support plate 36 is fixed between the two connecting plates 35, located below the docking slots 31.

[0025] Working principle: The operator places the grating frame 9 with flat steel 91 in the assembly station 21 beforehand. The crossbar is placed in the docking slot 31 and held in place by the support plate 36 below the slot. The clamping drive mechanism 5 drives the clamping plate 34 to move, clamping the crossbar against the inner wall of the docking slot 31. Simultaneously, the connecting plate 35, connected to the clamping plate 34, moves the support plate 36 away from directly below the docking slot 31. The length of the docking slot 31 perfectly matches the length of the crossbar. The lifting drive mechanism 4 drives the lifting seat 3 to descend, bringing the crossbar in the docking slot 31 close to and aligned with the notch of the flat steel 91 in the assembly station 21. At this time, the downward hydraulic cylinder 8 drives the downward pressing seat 7 to descend. The downward pressing block 71 of the downward pressing seat 7 enters the docking slot 31, pressing down on the crossbar and forcing it into the notch of the flat steel 91, thus improving assembly efficiency.
