Technical Field

[0001] This utility model relates to the field of wear-resistant plate welding technology, specifically a fixing device for welding wear-resistant plates. Background Technology

[0002] Wear-resistant steel plate, also known as wear-resistant steel plate, is a special type of steel plate designed for use under conditions of large-area wear. It is usually made by bonding a certain thickness of alloy wear-resistant layer with high hardness and excellent wear resistance to the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity through a welding method.

[0003] The prior art discloses a bimetallic wear-resistant plate welding and fixing mechanism with application number CN202323379899.6. The mechanism includes a processing table, in which bimetallic wear-resistant plates are stacked inside a groove. A welding device is installed on the processing table and slidably connected to a sliding rod. The sliding rod is installed between two baffles on the inner side of the processing table. At least one set of fixing mechanisms can be detachably connected to both baffles of the processing table. In this invention, by providing at least one set of detachably connected fixing mechanisms at the edge baffles of the processing table, the stacked bimetallic wear-resistant plates on the processing table can be pressed and fixed at any position on both sides. The adjustment direction is not limited by the processing table, allowing for free pressing and fixing of the bimetallic wear-resistant plates on the processing table. By installing a concave plate and bolt rod, the fixing mechanism can be quickly installed at the edge baffles of both sides of the processing table, enabling free disassembly and convenient use.

The metal horizontal plate 11 is threaded to the bottom surface of the metal frame 12, and the connector 2 is threaded to the upper end of the welding workbench 3. The metal horizontal plate 11 is installed on the upper end of the welding workbench 3, and the connector 2 is inserted into the inner wall surface of the metal horizontal plate 11. The connector 2 is inserted into the connection between the connector 2 and the welding workbench 3. Then, by rotating the nut, the metal horizontal plate 11 and the welding workbench 3 can be limited. The pushing assembly 13 is slidably connected to the upper end of the metal frame 12.

[0027] The actuating assembly 13 includes an electric push rod 131, a sliding metal plate 132, a supporting metal plate 133, a support frame 134, a limiting metal rod 135, a coil spring 136, and a connecting block 137. The connecting block 137 is inserted into the upper end of the support frame 134 and into the lower end of the piston rod inside the electric push rod 131. The connecting block 137 is inserted into the connection between the electric push rod 131 and the support frame 134, thereby enabling the support frame 134 and the electric push rod 131 to be connected. The electric push rod 131 and the support frame 134 are connected by a plug-in joint for easy disassembly and replacement. A helical spring 136 is installed at the lower end of the limiting metal rod 135 and at the upper end of the support frame 134. The helical spring 136 can push the limiting metal rod 135 downwards, thereby adjusting the distance between the support frame 134 and the limiting metal rod 135. A pin is provided at the connection between the support frame 134 and the limiting metal rod 135, which can secure the support frame 134... The limiting operation is performed between the 34 and the limiting metal rod 135. The support frame 134 is installed at the lower end of the internal piston rod of the electric push rod 131. The bearing metal plate 133 is installed at the lower end of the electric push rod 131. The electric push rod 131 is slidably connected to the inner surface of the upper end of the metal frame 12. There are four electric push rods 131. Two electric push rods 131 form a group. The two groups of electric push rods 131 are distributed front and back. Two electric push rods 131 on the same side are distributed on the left and right sides of the upper end of the metal frame 12. The sliding metal plate 132 is threaded to the surface of the bearing metal plate 133. The sliding metal plate 132 is slidably connected to the upper end of the metal frame 12. The bearing metal plate 133 is slidably connected to the top surface of the metal frame 12.

[0028] When in use, push the metal horizontal plate 11 upward so that the top surface of the metal horizontal plate 11 connects with the inner top surface of the welding workbench 3.

[0029] Push the connector 2 into the connection between the metal horizontal plate 11 and the welding workbench 3, and then rotate the nut. The nut rotates on the threaded rod surface of the connector 2, thereby limiting the position of the metal horizontal plate 11.

[0030] Push the metal frame 12 downward so that it is inserted into the outward end of the metal cross plate 11. Then rotate the nut to fix the metal frame 12 and the metal cross plate 11 with threads, thereby determining the position of the metal frame 12.

[0031] Pushing the limiting metal rod 135 upwards causes it to insert into the support frame 134. At the same time, the helical spring 136 is compressed between the limiting metal rod 135 and the support frame 134.

[0032] The supporting metal plate 133 is pushed downward, and the bottom surface of the supporting metal plate 133 is connected to the top surface of the metal frame 12. Then, a sliding metal plate 132 is slidably connected to the surface of the supporting metal plate 133. A threaded rod is inserted between the supporting metal plate 133 and the sliding metal plate 132, thereby determining the position of the supporting metal plate 133.

[0033] The electric push rod 131 is pushed downward, so that the electric push rod 131 and the supporting metal plate 133 are threaded together, and the piston rod inside the electric push rod 131 passes through the middle position of the metal frame 12.

[0034] The support frame 134 is pushed upward to connect the support frame 134 and the internal piston rod of the electric push rod 131. A plug-in block 137 is plugged into the connection point to fix the support frame 134 and the electric push rod 131.

[0035] A wear-resistant plate is placed on the top surface of the welding workbench 3. Then, the electric push rod 131 is activated, which pushes the support frame 134 and the limiting metal rod 135 downward. The bottom surface of the limiting metal rod 135 connects with the top surface of the wear-resistant plate, thereby enabling the welding operation of the wear-resistant plate.
